Background
[0002] The flight characteristics of a golf ball after being struck by a golf club are dependent
on not only on the swing of the golf club but also on the golf club itself. For example,
flight characteristics of the golf ball, such as fades, draws, launch angles, ball
spin, and speed are impacted by the design of the golf club. By adjusting one or more
design properties of the golf club, the flight characteristics of the golf ball can
be improved, thereby increasing golf club performance. In some examples, adjusting
a center of gravity (CG) and/or a moment of inertia (MOI) of a head of the golf club
through selective weight placement impacts the flight characteristics of the golf
ball. However, these adjustable weights need to be both securely attached to the golf
club head and selectively moveable. As such, improvements to adjustable weight assemblies
for golf club heads are desired.
Summary
[0003] In an aspect, the technology relates to a golf club head including: a body having
an outer surface; a recessed channel defined in the outer surface of the body; and
a weight assembly including: a weight at least partially disposed within the recessed
channel and configured to slide therein; a cover adapted to releasably secure the
weight within the recessed channel, the cover including: a first end and an opposite
second end; a rabbet extending at least partially between the first end and the second
end, the rabbet formed by at least two walls sized and shaped to at least partially
receive the weight and allow the weight to slide therein, wherein one or more of the
at least two walls have a retention rib extending therefrom, the retention rib elongated
in a direction between the first end and the second end and discontinuous in the elongated
direction; and a fastener receiver disposed opposite of the rabbet; and a fastener
coupling the cover to the body at the fastener receiver, wherein the fastener is configured
to move the cover between at least two positions, a first position whereby the weight
is selectively slidable relative to the body and a second position whereby the weight
is secured relative the body.
[0004] In an example, the retention rib includes a first rib and a second rib separated
by a gap, the gap configured to allow the weight to be at least partially received
within the rabbet. In another example, the gap is disposed proximate the first end
of the cover. In yet another example, a slit is formed in the weight, the slit slidably
engages with the retention rib. In still another example, the retention rib extends
from an outer wall of the at least two walls of the cover. In an example, the retention
rib is disposed proximate a distal end of the outer wall. In another example, both
the first end and the second end of the cover define an end wall, the end walls of
the first and second ends are devoid of a projection.
[0005] In another aspect, the technology relates to a golf club head including: a body having
an outer surface; a recessed channel defined in the outer surface of the body; and
a weight assembly including: a weight at least partially disposed within the recessed
channel and configured to slide therein, wherein a slit is defined in the weight;
a cover adapted to releasably secure the weight within the recessed channel, the cover
including: a first end and an opposite second end; a rabbet extending at least partially
between the first end and the second end, the rabbet formed by at least an outer wall
of the cover, wherein a retention rib extends from the outer wall and configured to
slidably engage with the slit of the weight; and a fastener receiver disposed opposite
of the rabbet; and a fastener coupling the cover to the body at the fastener receiver,
wherein the fastener is configured to move the cover between at least two positions,
a first position whereby the weight is selectively slidable relative to the body and
a second position whereby the weight is secured relative the body.
[0006] In an example, the retention rib and the fastener receiver are disposed on opposite
sides of the cover. In another example, the retention rib includes at least two discrete
sections. In yet another example, at least one hollow is defined in the weight opposite
of the slit. In still another example, the at least one hollow includes a hollow fully
defined in the weight and a hollow partially defined in the weight. In an example,
the rabbet engages the weight such that the weight moves with the cover between the
at least two positions. In another example, the fastener is the only component of
the weight assembly that extends into an interior cavity of the body.
[0007] In another aspect, the technology relates to a golf club head including: a body having
an outer surface; a recessed channel defined in the outer surface of the body; and
a weight assembly including: a weight at least partially disposed within the recessed
channel and configured to slide therein; a cover adapted to releasably secure the
weight within the recessed channel, the cover including: an outside surface and an
opposite inside surface; a first end and an opposite second end, wherein an end wall
is defined at both the first end and the second end; a rabbet extending at least partially
between the first end and the second end, the rabbet sized and shaped to at least
partially receive the weight and allow the weight to slide therein, wherein the end
walls of the first and second ends define a terminal end of the rabbet, and wherein
a thickness of the cover at the end walls between the outside surface and the inside
surface is equal to a thickness of the cover at a midpoint of the rabbet between the
outside surface and the inside surface; and a fastener receiver disposed opposite
of the rabbet; and a fastener coupling the cover to the body at the fastener receiver,
wherein the fastener is configured to move the cover between at least two positions,
a first position whereby the weight is selectively slidable relative to the body and
a second position whereby the weight is secured relative the body.
[0008] In an example, a retention rib configured to engage the weight extends from at least
one of the end walls. In another example, a retention rib configured to engage the
weight extends from both of the end walls. In yet another example, the retention rib
has a square-shaped cross-section. In still another example, the retention rib is
discontinuous and a gap is formed within the retention rib. In an example, a length
of the rabbet is about three times a length of the gap of the retention rib.

Detailed Description
[0011] The technologies described herein contemplate a golf club head, such as a fairway
metal, driver, or other golf club head, that includes an adjustable weight assembly.
Through the weight balance of the golf club head, the flight characteristics of the
golf ball can be improved, thereby increasing golf club performance. In the examples
described herein, the weight assembly enables for the CG and/or MOI of a head of the
golf club to be adjusted through selective weight placement to impact the flight characteristics
of the golf ball, such as fades, draws, launch angles, ball spin, and speed. Additionally
or alternatively, the weight assembly enables for the swing weight of the golf club
head to be adjustable (e.g., increasing or decreasing the weight of the club head).
[0012] In examples, the present technologies provide a golf club head with a recessed channel
defined therein. A slidable weight is disposed at least partially within the channel
and secured therein by a cover and a fastener. The cover is configured to retain the
weight within the channel indirectly so that the fastener never engages with the weight.
This configuration enables for the size, shape, and/or density of the weight to be
defined so that the CG and MOI of the golf club head can be finely tuned. Additionally,
the cover includes additional features that increase securement of the weight within
the channel and reduce undesirable rattling or movement during the golf club swing.
Furthermore, the weight assemblies described herein allow for the weight to be adjusted
quickly and easily without requiring any component to be fully detached from the club
head. Thereby reducing lost or misplaced components during club head adjustment. In
an aspect, the weight is engaged with the cover so that the two components can move
together with respect to the golf club head. Additionally, the weight is restricted
from tilting relative to the cover so as to reduce or prevent binding of the weight
within the channel.
[0013] FIG. 1 is a perspective view of a sole 102 of a golf club head 100 with an exemplary
weight assembly 104. The golf club head 100 is a metalwood-type golf club head having
a body 106 that includes a striking face 108 positioned towards the front of the club
head 100 and having a lower edge 110 and an upper edge 112 (e.g., shown in FIG. 8)
each extending between a toe 114 and heel 116 of the club head 100. The sole 102 extends
from the lower edge 110 on the bottom side of the club head 100 and a crown 118 extends
from the upper edge 112 on the top of the club head 100. The sole 102, the striking
face 108, and the crown 118 are coupled together so as to define an outer surface
120 of the body 106 with an interior cavity 122 (shown in FIG. 2) formed within. A
hosel 124 is disposed at the heel 116 and is configured to couple to a shaft (not
shown). In some examples, a skirt 126 (shown in FIG. 8) may also form a portion of
the club head 100 and is positioned between the crown 118 and the sole 102. In such
examples and for purposes of this application, the crown 118 may still be considered
to be attached or coupled to the sole 102, via the skirt 126. Furthermore, the body
106 may form any type club head, such as an iron-type club head or hybrid-type club
head, as required or desired.
[0014] In operation, the sole 102 generally provides the lower surface of the club head
100 when the club head 100 is placed in an address position. The club head 100 defines
a center of gravity (CG) and a moment of inertia (MOI) that impact flight characteristics
of a golf ball (not shown) when hit with the striking face 108. The weight assembly
104 is coupled to the club head 100 such that the CG and/or the MOI of the club head
100 can be selectively adjusted as required or desired. In the example, the weight
assembly 104 includes a movable weight 128, a cover 130 configured to secure the weight
128 in place, and a fastener 132 for coupling the weight assembly 104 to one or more
other portions of the club head 100. In some examples, the weight 128 may be formed
from tungsten. In examples, the weight 128 may be between about 2 grams to 15 grams.
In some specific examples, the weight 128 may be about 9 grams.
[0015] A recessed elongated channel 134 is formed in the outer surface 120 of the club head
100. More specifically, the channel 134 is substantially linear and defined in the
sole 102 of the club head 100. In other examples, the channel 134 may be defined at
any other location of the body 106 (e.g., the crown 118 or the skirt 126) as required
or desired. The channel 134 is sized and shaped to receive at least a portion of the
weight 128 so that the weight 128 can be slidable therein. In the example, the channel
134 extends substantially linearly in a toe 114 - heel 116 direction so that the CG
and the MOI of the club head 100 can be adjusted (by selectively moving the weight
128) for fade or draw bias. The channel 134 can be angularly offset from the plane
of the striking face 108 as illustrated in FIG. 1. In other examples, the channel
134 may extend substantially parallel to the striking face 108. In the example, the
fastener 132 is positioned proximate to the heel side of the channel 134. In other
examples, the fastener 132 may be positioned at any other location relative to the
channel 134 to enable the weight assembly 104 to function as described herein. For
example, at approximately a midpoint of the channel 134 as described in reference
to FIG. 26 or proximate the toe side of the channel 134.
[0016] In operation and through use of the fastener 132, the cover 130 is coupled to the
body 106 and extends at least partially over the channel 134 so as to selectively
secure the weight 128 to the club head 100. Additionally, the cover 130 covers at
least a portion of the channel 134 so as to reduce dust and dirt from accumulating
therein. However, the fastener 132 is separate from the weight 128 and only indirectly
(e.g., via the cover 130) secures the weight 128 to the club head 100. In examples,
the fastener 132 and the cover 130 are adapted to retain the weight 128 in the channel
134 only by contact with the cover 130 such that the fastener 132 never engages the
weight 128. As described herein, when the fastener 132 indirectly retains the weight
128, the fastener 132 never engages the weight 128 directly and it is a separate component
(e.g., the cover 130) that directly engages the weight 128 for securement to the club
head 100.
[0017] The cover 130 may be loosened or completely removed, via the fastener 132, from the
club head 100 to enable the weight 128 to slide within the channel 134 and selectively
adjust the CG and the MOI as required or desired. Because the weight 128 is selectively
moveable, the weight assembly 104 (e.g., the fastener 132, the weight 128, and the
cover 130) enables the movement of the weight 128, while also securing the weight
128 to one or more portions of the club head 100 so that undesirable movement (e.g.,
during a club swing) is reduced or prevented. By separating the fastener 132 from
the weight 128, the size, shape, and/or density of the weight 128 may be configured
so that the CG and the MOI of the club head 100 may be more finely tuned, thereby
increases the performance of the golf club head 100. The weight assembly 104 is described
further below.
[0018] FIG. 2 is a cross-sectional view of the golf club head 100 taken along line 2-2 in
FIG. 1 and showing the weight assembly 104 in a locked configuration 136. FIG. 3 is
a cross-sectional view of the weight assembly 104 taken along line 3-3 in FIG. 2.
Referring concurrently to FIGS. 2 and 3, when the weight assembly 104 is in the locked
configuration 136, the cover 130 is disposed within the channel 134 and the weight
128 is secured within the channel 134 such that movement is restricted. In the example,
to lock the cover 130 to the body 106, the fastener 132 may be a threaded bolt that
threadingly engages with a nut 138 positioned within the heel end of the channel 134.
In some examples, the nut 138 may be integrally formed within the body 106.
[0019] When the cover 130 is in the locked configuration 136, an exterior surface 140 of
the cover 130 is substantially aligned (e.g., flush) with the outer surface 120 of
the body 106. Additionally, the fastener 132 defines a fastener axis 142. In the example,
the fastener axis 142 is disposed at an angle 144 relative to a plane 146 that is
normal to the exterior surface 140 of the cover 130 proximate the fastener 132. The
angle 144 defines the orientation that the cover 130 may move relative to the body
106. The angle 144 may be between about 0° (e.g., aligned with the plane 146) and
about 88°. In examples, the angle 144 may be between about 20° and 50°. In one example,
the angle 144 may be about 45°.
[0020] In the example, only a single fastener 132 is used to couple the cover 130 to the
body 106 and the fastener 132 is positioned at the heel end of the weight assembly
104. As such, to connect the toe end of the cover 130 to the body 106, the cover 130
may include one or more projections 148 that extend from the toe end. The projection
148 is sized and shaped to be received within one or more corresponding chambers 150
defined at the toe end of the channel 134. When the weight assembly 104 is in the
locked configuration 136, the projection 148 is received at least partially within
the chamber 150 and engaged therewith. By engaging the cover 130 to the body 106 at
a position opposite from the fastener 132, when the weight 128 is positioned away
from the fastener 132, the cover 130 still enables securement of the weight 128 within
the channel 134 and reduces or prevents movement of the weight 128 in the locked configuration
136. In the example, the projection 148 extends in the toe-heel direction of the cover
130 and includes at least one oblique surface 152 that frictionally engages with a
corresponding at least one oblique surface 154 of the chamber 150. In some examples,
the oblique surfaces 152, 154 may be substantially parallel to the fastener axis 142.
In other examples, the oblique surfaces 152, 154 may be oriented at a different angle
than the fastener axis 142 (e.g., steeper or shallower angles). Additionally or alternatively,
the projection 148 and chamber 150 may extend substantially orthogonal to the toe-heel
direction (e.g., in and out of the page of FIG. 2).
[0021] The cover 130 may also be engaged with the body 106 at one or more intermediate positions
between the fastener 132 and the opposite end. A seat 156 may protrude into the channel
134 at a location between the toe end and the heel end, for example, proximate a midpoint
location of the channel 134. The seat 156 is sized and shaped to be received within
a corresponding notch 158 defined in the cover 130. When the weight assembly 104 is
in the locked configuration 136, the seat 156 is received at least partially within
the notch 158 and engaged therewith. This engagement of the cover 130 to the body
106 at a position away from the fastener 132, also secures the weight 128 within the
channel 134 and reduces or prevents movement of the weight 128 in the locked configuration
136. In the example, the seat 156 extends in the toe-heel direction of the channel
134 and includes at least one oblique surface 160 that frictionally engages with a
corresponding at least one oblique surface 162 of the notch 158. In some examples,
the oblique surfaces 160, 162 may be substantially parallel to the fastener axis 142.
In other examples, the oblique surfaces 160, 162 may extend at angle relative to the
bottom of the channel 134 between about 3° and 88°. In one example, the oblique surfaces
160, 162 may extend at an angle relative to the bottom of the channel 134 of about
30°.
[0022] A cam 164 may also protrude into the channel 134 at a location between the toe end
and the heel end, for example, between the seat 156 and the chamber 150. The cam 164
is sized and shaped to receive within a corresponding cutout 166 defined in the cover
130. When the weight assembly 104 is in the locked configuration 136, the cam 164
is received at least partially within the cutout 166. The cam 164 and the cutout 166
are described further below in reference to FIG. 4.
[0023] In the example, the cover 130 is substantially L-shaped with a long leg 168 and a
short leg 170. In the locked configuration 136, the long leg 168 forms the exterior
surface 140 and the short leg 170 extends within the channel 134. The channel 134
is formed from two opposing sidewalls 172, 174 and a bottom track 176 offset from
the outer surface 120 of the body 106. The long leg 168 of the cover 130 opposes the
track 176 of the channel 134 and the short leg 170 of the cover 130 is adjacent to
one of the sidewalls 172. The seat 156 and the cam 164 may protrude from the sidewall
172 of the channel 134 and the corresponding notch 158 and cutout 166 may be defined
in the short leg 170 of the cover 130. When the weight 128 is secured within the channel
134 and in the locked configuration 136, the weight 128 is compressed between cover
130 and one or more walls (e.g., the sidewall 174 and/or the track 176) of the channel
134. As such, the weight 128 is frictionally secured to one or more portions of the
club head 100 by the weight assembly 104.
[0024] Additionally, the weight 128 may be slidably coupled to the cover 130. The long leg
168 of the cover 130 may include a flange 178 extending therefrom. The flange 178
is sized and shaped to be received at least partially within a corresponding groove
180 defined in the weight 128. In the locked configuration 136, a portion of the weight
128 is not covered by the cover 130 and exposed within the channel 134 such that the
portion forms part of the outer surface 120 of the body 106. This enables for the
location of the weight 128 within the channel 134 to be easily determined by visual
inspection.
[0025] FIG. 4 is a cross-sectional view of the club head 100 taken along line 2-2 in FIG.
1 and showing the weight assembly 104 in an unlocked configuration 182. FIG. 5 is
a cross-sectional view of the weight assembly 104 taken along line 5-5 in FIG. 4.
Referring concurrently to FIGS. 4 and 5, when the weight assembly 104 is in the unlocked
configuration 182, at least a portion of the cover 130 is lifted and raised out of
the channel 134 such that the weight 128 is selectively slidable (e.g., along a toe-heel
direction 184) within the channel 134. In the example, the fastener 132 may be coupled
to the cover 130 (e.g., with a lock washer 186 (shown in FIG. 16)), so that the cover
130 moves along the fastener axis 142 (shown in FIG. 2) upon rotation of the fastener
132. The cover 130 and the fastener 132 may be completely removed from the body 106
as required or desired so as to completely remove the weight 128 from the channel
134. However, in examples, moving the weight assembly 104 between the locked configuration
136 (shown in FIGS. 2 and 3) and the unlocked configuration 182 does not require that
the weight assembly 104 be uncoupled from the body 106. As such, in the unlocked configuration
182, the cover 130 may remain coupled to the body 106 so that it is less likely that
the components become lost or misplaced. In some examples, the fastener 132 and/or
the nut 138 may include a hard stop (not shown) that prevents the fastener 132 from
being completely de-threaded from the club head 100 as required or desired.
[0026] Since only a single fastener 132 is used to couple the cover 130 to the body 106
and the fastener 132 is positioned at the heel end of the weight assembly 104, the
cam 164 may be used to assist the toe end of the cover 130 with lifting from the channel
134 in the unlocked configuration 182. This enables the weight 128 to more easily
slide to positions away from the fastener 132. In the example, the cam 164 extends
in the toe-heel direction of the channel 134 and includes at least one camming surface
188 that slidingly engages with a corresponding camming surface 190 of the cutout
166. As the cover 130 moves from the locked configuration 136, where the cam 164 is
received within the cutout 166, toward the unlocked configuration 182, the camming
surfaces 188 190 slide against one another to lift the toe end of cover 130. In some
examples, when the weight assembly 104 is in the unlocked configuration 182, a portion
of the cover 130 may be supported on the cam 164. The camming surfaces 188, 190 may
be substantially parallel to the fastener axis 142.
[0027] Additionally, in the unlocked configuration 182, the notch 158 may lift away from
the seat 156 to disengage the oblique surfaces 160, 162 (shown in FIG. 2). In the
unlocked configuration 182, the notch 158 may lift partially or completely for the
seat 156. The projection 148 may also lift away from the chamber 150. However, the
projection 148 may remain at least partially engaged with the chamber 150 so that
the weight 128 cannot slide out of the toe end of the cover 130 and remain within
the channel 134 in the unlocked configuration 182. Furthermore, because the weight
128 is engaged with the cover 130 (e.g., the flange 178 and the groove 180), the weight
128 moves with the cover 130 between the locked configuration 136 and the unlocked
configuration 182. This enables the weight 128 to be more easily slidable in the unlocked
configuration 182.
[0028] In some examples, one or more of the weight 128, the cover 130, and the channel 134
may include complementary features (e.g., corresponding detents 192 on the cover 130
and recesses (not shown) on the weight 128) that index the location of the weight
128 to the channel 134 and/or the cover 130. These complementary indexing features
may provide tactile and/or audible feedback when the weight 128 is moved. Additionally,
the complementary indexing features may also provide increased resistance to the relative
movement between the weight 128 and the channel 134 and/or cover 130 when the weight
assembly 104 is in the locked configuration 136.
[0029] FIG. 6 is a perspective view of the sole 102 of the golf club head 100 with another
weight assembly 200. FIG. 7 is a cross-sectional view of the weight assembly 200 taken
along line 7-7 in FIG. 6. Certain components are described above, and thus, are not
necessarily described further. Referring concurrently to FIGS. 6 and 7, the weight
assembly 200 includes a recessed channel 202 defined within the sole 102 of the body
106 of the club head 100, however, the channel 202 extends substantially linearly
in a front-rear direction so that the CG and the MOI of the club head 100 can be adjusted
for launch angle bias. The channel 202 can be substantially orthogonal to the striking
face 108 as illustrated in FIG. 6. In other examples, the channel 202 may extend at
either an acute or obtuse angle relative to the striking face 108. The weight assembly
200 also includes a slidable weight 204, a cover 206, and a fastener 208. In this
example, the fastener 208 is positioned proximate to the rear of channel 202 and opposite
of the striking face 108. In other examples, the fastener 208 may be positioned at
any other location relative to the channel 202 to enable the weight assembly 200 to
function as described herein. For example, at approximately a midpoint of the channel
202 or proximate the striking face 108 side of the channel 202.
[0030] In this example, the channel 202 is formed by two opposing sidewalls, a cover sidewall
210 and an undercut sidewall 212, and a bottom track 214 offset from the outer surface
120 of the body 106. A partial wall 216 also extends from the bottom track 214. Here,
the cover 206 is located adjacent to the cover sidewall 210 and includes an angled
surface 218. As such, when the weight assembly 200 is in a locked configuration (e.g.,
FIG. 7), the cover 206 generates a compressive force 220 along the angled surface
218 that acts in both a downward direction and a transverse direction to secure the
weight 204 between the cover 206 and the undercut sidewall 212. Accordingly, the weight
204 is frictionally secured to one or more portions of the club head 100 by the weight
assembly 200 and at least partially underneath the angled surface 218 and the undercut
sidewall 212. The weight 204 is at least partially trapezoidal in cross-sectional
shape so that the undercuts of the sidewall 212 and the cover 206 assist in retaining
the weight 204 within the channel 202. Additionally, the cover 206 engages with the
partial wall 216 so that the portion of the cover 206 away from the fastener 208 is
restricted from moving within the channel 202 (e.g., bending or flexing) towards the
undercut sidewall 212. Furthermore, the partial wall 216 is substantially parallel
to the fastener axis (not shown) of the fastener 208 so that the cover 206 is guided
between the locked and unlocked configuration. In some example, the weight assembly
200 may include the seat/notch interface as described above to further engage the
cover 206 within the channel 202 and increase the securement of the weight 204 to
one or more portions of the club head 100.
[0031] FIG. 8 is a perspective view of the golf club head 100 with another weight assembly
300. Certain components are described above, and thus, are not necessarily described
further. In this example, the club head 100 includes the skirt 126 positioned between
the crown 118 and the sole 102, opposite of the striking face 108. The weight assembly
300 includes a recessed channel 302 defined within the skirt 126 of the body 106 of
the club head 100 and extends along the rear perimeter of the club head 100 such that
the channel 302 has a curved shape. The weight assembly 300 also includes a slidable
weight 304, a cover 306, and a fastener 308. In this example, the fastener 308 is
coupled to the heel 116 side of the body 106. In other examples, the fastener 308
may be coupled to the toe 114 side of the body 106 as required or desired. The weight
assembly 300 may include one or more of the weight assembly features described herein
to enable the CG and the MOI of the club head 100 to be adjustable for fade-draw bias,
while securing the weight 304 in a locked configuration (as shown in FIG. 8).
[0032] FIG. 9 is a perspective view of the sole 102 of the golf club head 100 with another
weight assembly 400. FIG. 10 is a top view of the golf club head 100 shown in FIG.
9 with a portion of the crown 118 removed. Certain components are described above,
and thus, are not necessarily described further. Referring concurrently to FIGS. 9
and 10, the weight assembly 400 includes a recessed channel 402 defined within the
sole 102 of the body 106 of the club head 100 that extends substantially linearly
in the toe 114 - heel 116 direction. The weight assembly 400 also includes a slidable
weight 404, a cover 406, and a fastener 408. The channel 402 includes a bottom track
410 that the weight 404 is slidable on. In this example, the fastener 408, and also
a nut 412 that the fastener 408 couples to, are offset from the track 410 and positioned
towards the rear of the body 106. By offsetting the fastener 408 from the track 410,
the length of the track 410 can be extended in the toe-heel direction so that the
weight 404 can be positioned at a greater number of locations on the sole 102. In
other examples, the fastener 408 may be offset from the track 410 and positioned towards
the front and the striking face 108 of the body 106 as required or desired.
[0033] In this example, one or more support ribs 414 may extend from the channel 402 and
within the interior cavity 122 of the body 106. The support ribs 414 are substantially
orthogonal to the length of the channel 402. The support ribs 414 provide structural
strength to the channel 402 so that the channel 402 is resistant to deformation when
the cover 406 compresses the weight 404 therein. In some examples, the support ribs
414 may extend the entire distance between the sole 102 and the crown 118 within the
interior cavity 122.
[0034] FIG. 11 is a cross-sectional view of the weight assembly 400 taken along line 11-11
in FIG. 9. FIG. 12 is a cross-sectional view of the weight assembly 400 taken along
line 12-12 in FIG. 9. Certain components are described above, and thus, are not necessarily
described further. Referring concurrently to FIGS. 11 and 12, the weight assembly
400 is illustrated in a locked configuration so that the weight 404 is secured within
the channel 402. In this example, the weight 404 includes an elastomeric material
416 (e.g., a rubber-based material) that engages with the channel 402 and/or the cover
406 and further increase securement of the weight 404 in the locked configuration.
Additionally, the elastomeric material 416 decreases rattling of the weight 404 within
the channel 402 during the swing of the club head.
[0035] In this example, the channel 402 is formed from two opposing sidewalls 418, 420 and
the track 410. One sidewall 420 may include an elongate fin 422 extending into the
channel 402. The weight 404 is sized and shaped to be received at least partially
within the channel 402 and includes a bottom surface 424 that is positioned adjacent
to the track 410 and a slot 426 that engages with the fin 422. Additionally, opposite
of the slot 426, the weight 404 includes a groove 428 that engages with a flange 430
of the cover 406. The elastomeric material 416 may be coupled to the weight 404 so
that the material 416 extends from the bottom surface 424 and also into the slot 426.
In one example, the elastomeric material 416 may be a unitary piece that extends through
one or more holes within the weight 404. In other examples, the elastomeric material
416 may be adhered to one or more external surfaces of the weight 404. In still other
examples, at least a portion of the elastomeric material 416 may form the weight 404
itself.
[0036] In operation, when the cover 406 is in the locked configuration, the flange 430 engages
with the groove 428 of the weight 404 and compresses the weight 404 into the channel
402. As such, the elastomeric material 416 may engage with the track 410 and the fin
422 of the channel 402. By engaging the elastomeric material 416 in more than one
location, securement of the weight 404 within the channel 402 increases. This reduces
undesirable movement and rattling of the weight 404 within the channel 402. In some
examples, the elastomeric material 416 may deform when compressed within the channel
402. Since the cover 406 engages with only a portion of the weight 404, when the cover
406 is lifted 432 for the unlocked configuration (not shown), the weight 404 can rotate
434 within the channel 402 so that the elastomeric material 416 may disengage from
the track 410 and the fin 422. This rotational movement 434 enables the weight 404
to be more easily slidable within the channel 402 while in the unlocked configuration
because the elastomeric material 416 is at least partially positioned away from the
channel surfaces. In some examples, the elastomeric material 416 extending from the
bottom surface 424 may be only proximate the groove 428 so as to increase rotational
movement 434 of the weight 404.
[0037] The cover 406 is substantially L-shaped in cross-section (see FIG. 12) and receives
at least a portion of the weight 404 therein. The cover includes a first leg 436 that
has the flange 430 and a second leg 438 that is adjacent to the sidewall 418 of the
channel 402. The flange 430 may be substantially parallel to the second leg 438 so
as to increase the structural rigidity of the cover 406 in the lengthwise direction.
The second leg 438 may extend at least partially within a depression 440 of the track
410 so as to decrease bending of the cover 406 while in the locked configuration.
Additionally, in the example, a projection 442 of the cover 406 may be substantially
cylindrical in shape. The projection 442 is received within a corresponding cylindrical
chamber 444. This projection 442 and chamber 444 structure increases the engagement
of the cover 406 with the body 106 in the locked configuration (as illustrated in
FIG. 11). In some examples, a projection axis 446 of the projection 442 may be substantially
parallel to a fastener axis 448. This orientation guides the movement of the cover
406 between the locked configuration and the unlocked configuration. In some examples,
the projection 442 may include a tapered nose. In this example, the weight 404 and
the channel 402 may include complementary features 450 that index the location of
the weight 404 to the channel 402.
[0038] FIG. 13 is a cross-sectional view of another weight assembly 500. Certain components
are described above, and thus, are not necessarily described further. Similar to the
example described in FIGS. 9-12, in this example, the weight assembly 500 includes
a recessed channel 502 defined within the body 106 of the club head. The weight assembly
500 also includes a slidable weight 504 and a cover 506. The cover 506 is shown in
a locked configuration and a slot 508 of the weight 504 is engaged with a fin 510
of the channel 502. However, in this example, a bottom surface 512 of the weight 504
is positioned directly against a track 514 of the channel 502. Additionally, in this
example, the bottom surface 512 of the weight 504 includes a hollow 516. The hollow
516 reduces fictional sliding forces on the weight 504, when the weight assembly 500
is in the unlocked configuration (not shown). The hollow 516 also enables for the
size and shape of the weight 504 to be formed while maintaining the required or desired
mass and/or density of the weight 504. In some examples, an elastomeric material (not
shown) may be disposed at least partially within the hollow 516.
[0039] FIG. 14 is a perspective view of the sole 102 of the golf club head 100 with another
weight assembly 600. Certain components are described above, and thus, are not necessarily
described further. The weight assembly 600 includes a recessed channel 602 defined
within the sole 102 of the body 106 of the club head 100. The channel 602 has a substantially
curved shape in the toe 114 - heel 116 direction so that the CG and the MOI of the
club head 100 can be adjustable for fade-drawn bias. In some examples, the curve of
the channel 602 matches the rear perimeter of the body 106, where the sole 102 and
the crown 118 are coupled together. The weight assembly 600 also includes a slidable
weight 604, a cover 606, and a fastener 608.
[0040] In this example, the fastener 608 is positioned in the concave area of the curved
channel 602 and towards the striking face 108 of the body 106. This position enables
the weight 604 to be positioned adjacent to the rear perimeter of the body 106 and
increase the adjustability of the CG and MOI of the club head 100, when compared to
having the fastener 608 positioned in the convex area of the curved channel 602 and
the weight 604 being closer to the striking face 108. Additionally, the weight 604
may slide completely from the toe 114 side to the heel 116 side and be located at
any position of the channel 602 even adjacent to the fastener 608. In other examples,
the fastener 608 may be positioned in the convex area of the curved channel 602 as
required or desired. The fastener 608 is also positioned at approximately the midpoint
of the channel 602. In other examples, the fastener 608 may be offset from the midpoint
of the channel 602, or two or more fastener 608 may be used to couple the cover 606
to the body 106 (e.g., at each end of the channel 602).
[0041] FIG. 15 is a cross-sectional view of the club head 100 taken along line 15-15 in
FIG. 14 and showing the weight assembly 600. FIG. 16 is a cross-sectional view of
the weight assembly 600 taken along line 16-16 in FIG. 14. FIG. 17 is a cross-sectional
view of the weight assembly 600 taken along line 17-17 in FIG 14. Certain components
are described above, and thus, are not necessarily described further. Referring concurrently
to FIGS. 15-17, the weight assembly 600 is illustrated in a locked configuration and
the weight 604 includes a bottom surface 610 and a groove 612. A tab 614 is disposed
adjacent to the groove 612. Additionally, the weight 604 includes an elastomeric material
614. In this example, the elastomeric material 614 is coupled to the weight 604 and
extends from the bottom surface 610 and also into the groove 612. The elastomeric
material 614 is oversized relative to the channel 602 (e.g., between a 0.1 millimeter
and 1.0 millimeter overlap) so that the material 614 may deform while being compressed
within the channel 602. In other examples, the elastomeric material 614 may be adhered
to the exterior surface of the weight 604. In yet other examples, the elastomeric
material 614 may at least partially form the weight 604 itself.
[0042] The cover 606 is substantially C-shaped with a flange 616 that engages with the groove
612 of the weight 604. Additionally, the cover 606 includes a top leg 618 and a side
leg 620 that is opposite of the flange 616. The top leg 618 has a thickness that is
greater than the flange 616 and the side leg 620 so as to increase the structural
rigidity of the cover 606 in a lengthwise direction. The fastener 608 is coupled to
the cover 606 by a lock washer 186 that enables the fastener 608 to rotate relative
to the cover 606 while allowing the cover 606 to move along a fastener axis 622 to
raise and lower the cover 606 relative to the channel 602.
[0043] In operation, when the cover 606 is in the locked configuration, the flange 616 of
the cover 606 is engaged within the groove 612 of the weight 604. This compresses
the weight 604 between the cover 606 and a bottom track 624 of the channel 602. In
the locked configuration, the elastomeric material 614 engages with both the cover
606 and the channel 602 to increase the securement of the weight 604 to one or more
portion of the club head 100. In some examples, a plurality of grooves 626 are defined
within the track 624 that the elastomeric material 614 deforms into the grooves 626
to facilitate securement of the weight 604 within the channel 602. Additionally, the
tab 614 of the weight 604 may be positioned proximate the outer surface 120 of the
body 106 so that the position of the weight 604 may be visible. When the weight assembly
600 is in the unlocked configuration (not shown), the cover 606 is lifted at least
partially out of the channel 602 so that the weight 604 may be selectively slidable
therein, for example, via the tab 614.
[0044] Each end of the cover 606 may include a substantially cylindrical projection 628
that is received within a corresponding cylindrical chamber 630 of the channel 602.
The projections 628 extend along a projection axis 632 that is substantially parallel
to the fastener axis 622. This orientation guides the movement of the cover 606 between
the locked configuration and the unlocked configuration. In some examples, the projections
628 may include a tapered nose. Additionally, the chamber 630 may be open into the
interior cavity 122 of the body 106 as illustrated in FIGS. 15 and 16. In other examples,
the chamber 630 may be closed off from the interior cavity 122. One or more support
ribs 634 may also extend from the track 624 and within the interior cavity 122 as
required or desired.
[0045] FIG. 18 is an exploded perspective view of the golf club head 100 with another weight
assembly 700. Certain components are described above, and thus, are not necessarily
described further. Similar to the example described in FIGS. 14-17, in this example,
the weight assembly 700 includes a recessed channel 702 defined within the body 106
of the club head 100 and the channel 702 has a substantially curved shape in the toe
114 - heel 116 direction. In some examples, the curve of the channel 702 matches the
rear perimeter of the body 106, where the sole 102 and the crown 118 are coupled together.
The weight assembly 700 also includes a slidable weight 704, a cover 706, and a fastener
708. At each end of the cover 706, projections 710 may extend for engagement within
the channel 702.
[0046] FIG. 19 is a cross-sectional view of the weight assembly 700 taken along line 19-19
in FIG. 18. Certain components are described above, and thus, are not necessarily
described further. The weight assembly 700 is illustrated in the locked configuration
in FIG. 19 and a bottom surface 712 of the weight 704 is positioned directly against
a track 714 of the channel 702. Additionally, in this example, the bottom surface
712 of the weight 704 includes a hollow 716. The hollow 716 reduces frictional sliding
forces on the weight 704, when the weight assembly 700 is in the unlocked configuration
(not shown). The hollow 716 also enables for the size and shape of the weight 704
to be formed while maintaining the required or desired mass and/or density of the
weight 704. In some examples, an elastomeric material (not shown) may be disposed
at least partially within the hollow 716.
[0047] Additionally, the cover 706 includes an angled surface 718 that abuts the weight
704. As such, when the weight assembly 700 is in a locked configuration (e.g., FIG.
19), the cover 706 generates a compressive force 720 along the angled surface 718
that acts in both a downward direction and a transverse direction to secure the weight
704 between the cover 706 and an undercut sidewall 722 of the channel 702. As such,
the weight 704 is frictionally secured by the weight assembly 700 to one or more portions
of the club head 100.
[0048] FIG. 20 is a partial cross-sectional perspective view of another weight assembly
800. FIG. 21 is another cross-sectional view of the weight assembly 800. Certain components
are described above, and thus, are not necessarily described further. Referring concurrently
to FIGS. 20 and 21, the cross-sectional views are substantially along a front-rear
direction of the golf club head and, for example, similar to the examples described
above in reference to FIGS. 16 and 17. The weight assembly 800 includes a recessed
channel 802 defined within the body 106. The weight assembly 800 also includes a slidable
weight (not shown), a cover 804, and a fastener 806. In this example, the channel
802 is defined by a bottom track 808 and two opposing sidewalls 810, 812. The bottom
track 808 includes an elastomeric material 814 coupled thereto and that extends at
least partially into the channel 802. The elastomeric material 814 engages with the
weight and further increases securement of the weight within the channel 802 in the
locked configuration. Additionally, the elastomeric material 814 decreases rattling
of the weight during the swing of the club head. Additionally or alternatively, the
elastomeric material 814 may be coupled to one or more of the sidewalls 810, 812 as
required or desired. In still other examples, the elastomeric material 814 can be
coupled to the cover 804.
[0049] In this example, the elastomeric material 814 extends along the longitudinal length
of the channel 802. At each end 816 of the elastomeric material 814, a portion of
the material may extend into an undercut area 818 within the channel 802 so as to
secure the elastomeric material 814 within the channel 802. In other examples, the
elastomeric material 814 may be adhered within the channel 802 or the cover 804 as
required or desired. The end 816 of the elastomeric material 814 may be offset 820
from a projection 822 of the cover 804 so that the elastomeric material 814 does not
interfere with the movement of the cover 804 between the locked and unlocked configurations
as described herein.
[0050] FIG. 22 is a perspective view of the sole 102 of the golf club head 100 with another
weight assembly 900 in a locked configuration. FIG. 23 is a cross-sectional view of
the weight assembly 900 taken along line 23-23 in FIG. 22. Certain components are
described above, and thus, are not necessarily described further. Referring concurrently
to FIGS. 22 and 23, the weight assembly 900 is illustrated in a locked configuration
and includes a recessed channel 902 defined within the sole 102 of the body 106 of
the club head 100. The channel 902 has a substantially curved shape in the toe 114
- heel 116 direction so that the CG and the MOI of the club head 100 can be adjustable
for fade-drawn bias. In some examples, the curve of the channel 902 matches the rear
perimeter of the body 106, where the sole 102 and the crown 118 are coupled together.
The weight assembly 900 also includes a toe-side slidable weight 904, a heel-side
slidable weight 906, a toe side cover 908, a heel side cover 910, and a fastener 912.
[0051] In this example, the fastener 912 is disposed within the channel 902 and divides
the weight assembly 900 approximately in half. By positioning the fastener 912 within
the channel 902 the size of the weight assembly 900 on the club head 100 is reduced.
Additionally, the mass of the fastener 912 is moved further rearward from the striking
face 108 than those examples described above. The weights 904, 906 extend from the
inner convex side of the covers 908, 910 as illustrated in FIG. 22. In other examples,
the weights 904, 906 may extend from the outer concave side of the covers 908, 910
as required or desired. In this example, two slidable weights 904, 906 are described
since the fastener 912 prevents a weight from sliding completely from the toe side
to the head side of the channel 902 and back. In some examples, the weight assembly
900 may include only one slidable weight and the fastener 912 and the covers 908,
910 are configured to allow the weight to pass between the toe 114 side and the heel
116 side. In other examples, the weight assembly 900 may include only one slidable
weight that requires the assembly to be completely disassembled so as to move the
weight from the toe side to the head side and back. In still other examples, the weights
904, 906 may be completely removable from the channel 902 as required or desired.
[0052] One end of each cover 908, 910 is engaged with the channel 902, for example, with
the projection/channel interface as described herein, while the other opposite end
of each cover 908, 910 is engaged with the fastener 912. In the example, the fastener
912 includes a washer 914 that is disposed below the head. The washer 914 is a substantially
cylindrical flange extending from the threaded shaft that engages with both corresponding
groove 916 within the covers 908, 910. When the weight assembly 900 is in the locked
configuration the covers 908, 910 are disposed within the channel 902 and secured
in place with the fastener 912, via the grooves 916, so that the weights 904, 906
cannot slide within the channel 902 and are locked in place. Additionally, the covers
908, 910 are flush with the outer surface 120 of the body 106. In some examples, the
portion of the covers 908, 910 that define the grooves 916 may extend all the way
to a bottom track 918 of the channel 902 so that overtightening of the fastener 912
is reduced or prevented.
[0053] FIG. 24 is a perspective view of the sole 102 of the golf club head 100 with the
weight assembly shown 900 in an unlocked configuration. FIG. 25 is a cross-sectional
view of the weight assembly 900 taken along line 25-25 in FIG. 24. Certain components
are described above, and thus, are not necessarily described further. Referring concurrently
to FIGS. 24 and 25, the weight assembly 900 is illustrated in an unlocked configuration.
When the weight assembly 900 moves from the locked configuration (shown in FIGS. 22
and 23), the fastener 912 is rotated so as to lift at least partially out of the channel
902. This movement of the fastener 912 also lifts the ends of the covers 908, 910
that are engaged with the washer 914 at least partially out of the channel 902 so
as to enable the weights 904, 906 to slide within the channel 902. In some examples,
the weights 904, 906 may be engaged with the respective cover 908, 910 so as to lift
away from the track 918 for ease of movement.
[0054] In some examples, the covers 908, 910 and the fastener 912 may be completely removed
from the body 106 as required or desired so as to completely remove the weights 904,
906 from the channel 902. However, moving the weight assembly 900 between the locked
configuration) and the unlocked configuration does not require that the weight assembly
900 be uncoupled from the body 106. As such, in the unlocked configuration, the covers
908, 910 remain coupled to the body 106 so that it is less likely that the components
become lost or misplaced.
[0055] In this example, when the covers 908, 910 are in the unlocked configuration, the
ends of the covers 908, 910 that are opposite of the fastener 912 and engaged with
the channel 902 (e.g., with the projection/channel interface) remain engaged with
the channel 902 and may form a pivot point that the covers 908, 910 rotate about.
In other examples, the ends of the covers 908, 910 that are opposite of the fastener
912 may lift at least partially out of the channel 902 as described herein. For example,
through a cam and cutout interface as described above.
[0056] FIG. 26 is a perspective view of the sole 102 of the golf club head 100 with another
weight assembly 1000. FIG. 27 is a cross-sectional view of the weight assembly 1000
taken along line 27-27 in FIG. 26. Certain components are described above, and thus,
are not necessarily described further. Referring concurrently to FIGS. 26 and 27,
the weight assembly 1000 includes a substantially linear recessed channel 1002 defined
within the sole 102. The weight assembly 1000 also includes a slidable weight 1004,
a cover 1006, and a fastener 1008. In this example, the fastener 1008 may be positioned
at approximately the midpoint of the channel 1002 and offset towards the rear of the
club head 100. By positioning the fastener 1008 at a midpoint location, the distance
between the fastener 1008 and the far end(s) of the cover 1006 is reduced so that
the engagement between the cover 1006 and the channel 1002 is increased for securement
of the weight 1004.
[0057] Similar to the example described above in reference to FIGS. 6 and 7, the channel
1002 is formed by two opposing sidewalls, a cover sidewall 1010 and an undercut sidewall
1012, and a bottom track 1014 offset from the outer surface 120 of the body 106. A
partial wall 1016 also extends from the bottom track 1014. The cover 1006 is located
adjacent to the cover sidewall 1010 and includes an angled surface 1018. As such,
when the weight assembly 1000 is in a locked configuration (e.g., FIG. 27), the cover
1006 generates a compressive force along the angled surface 1018 that acts in both
a downward direction and a transverse direction to secure the weight 1004 between
the cover 1006 and the undercut sidewall 1012. Accordingly, the weight 1004 is frictionally
secured by the weight assembly 1000 and at least partially underneath the angled surface
1018 and the undercut sidewall 1012. Additionally, the cover 1006 completely engages
with the partial wall 1016 via a groove 1020 so that the portion of the cover 1006
away from the fastener 1008 is restricted from moving within the channel 1002 (e.g.,
bending or flexing) towards the undercut sidewall 1012. Furthermore, the partial wall
1016 is substantially parallel to the fastener axis (not shown) of the fastener 1008
so that the cover 1006 guides the movement between the locked and unlocked configuration.
[0058] FIG. 28 is an exploded perspective view of the sole 102 of the golf club head 100
with another weight assembly 1100. FIG. 29 is a cross-sectional view of the weight
assembly 1100. Certain components are described above, and thus, are not necessarily
described further. Referring concurrently to FIGS. 28 and 29, the weight assembly
1100 includes a substantially linear recessed channel 1102 defined within the sole
102. The weight assembly 1100 also includes a slidable weight 1104, a cover assembly
1106, and a fastener 1108. In this example, the fastener 1108 may be positioned at
approximately the midpoint of the channel 1102 and offset towards the rear of the
club head 100. As described above, when the cover assembly 1106 is in the locked configuration,
the cover assembly 1106 is coupled to the body 106 so that the weight 1104 is be secured
within the weight assembly 1100 without movement or rattling. In this example, the
cover assembly 1106 is a four piece assembly including a fastener member 1110, two
opposing longitudinal members 1112, and a transverse member 1114.
[0059] When the cover assembly 1106 is moved towards the locked configuration (e.g., FIG.
29), the fastener 1108 is tightened to the body 106. The fastener 1108 engages with
the fastener member 1110 and moves the fastener member 1110 along the fastener axis
(not shown) and into the channel 1102. The fastener member 1110 has a tapered surface
that engages with both of the longitudinal members 1112 so that as the fastener member
1110 is pulled down within the channel 1102, the longitudinal members 1112 are also
pulled down within the channel 1102 and generate a compressive force 1116 along an
angled surface 1118. The compressive force 1116 acts in both a downward direction
and a transverse direction on the transverse member 1114 to position the transverse
member 1114 within the channel 1102 and compress the weight 1104 between the transverse
member 1114 and a sidewall 1120 of the channel.
[0060] Additionally, to reduce or prevent pull-out of the weight assembly 1100 from the
body 106, the transverse member 1114 may engage with an undercut 1122 of the channel
1102. The compressive force 1116 from the longitudinal members 1112 lock the transverse
member against the undercut 1122 so as to prevent movement. Additionally or alternatively,
a portion of the weight 1104 may engage with the sidewall 1120 of the channel 1102
so as to reduce pull out of the weight assembly 1100 from the body 106. Additionally,
the fastener member 1110 also pushes the longitudinal members 1112 away from the fastener
1108 (e.g., arrows 1124) so that ends 1126 of the members 1112 can engage with a corresponding
chamber 1128 in the channel 1102 and also reduce pull out of the weight assembly 1100
from the body 106.
[0061] FIG. 30 is a perspective view of the sole 102 of the golf club head 100 with another
weight assembly 1200. FIG. 31 is a cross-sectional view of the weight assembly 1200
taken along line 31-31 in FIG. 30. Certain components are described above, and thus,
are not necessarily described further. Referring concurrently to FIGS. 30 and 31,
the weight assembly 1200 is illustrated in an unlocked configuration and includes
a recessed channel 1202, a slidable weight 1204, a cover 1206, and a fastener 1208.
The structure, size, shape, and orientation of the channel 1202, the weight 1204,
and the fastener 1208 may be similar to any of the examples described above. In this
example, however, a width 1210 of the cover 1206 is extended towards the striking
face 108 so that the cover 1206 forms a greater portion of the sole 102 and does not
only cover a portion of the channel 1202.
[0062] In some examples, the cover 1206 may form greater than or equal to 75% of the surface
area of the sole 102. In other examples, the cover 1206 may form greater than to equal
to 50% of the surface area of the sole 102. In still other examples, the cover 1206
may form greater than or equal to 25% of the surface area of the sole 102. In still
further examples, the cover 1206 may be between about 10% and 90% of the surface area
of the sole 102. In other examples, the cover 1206 may be between about 25% and 75%
of the surface area of the sole 102.
[0063] By enlarging the cover 1206 of the weight assembly 1200, the golf club head structure
that forms the sole 102 of the body 106 can be reduced. In some examples, the cover
1206 can be manufactured from a lighter weight material (e.g., composite materials,
plastics, etc.) than the material that the body 106 is manufactured from. As such,
the weight saved by the configuration of the sole construction can be used at other
locations on the club head 100 as required or desired and further enable adjustment
of the CG and MOI of the club head 100 for improving golf ball flight characteristics.
In some examples, the weight saved by the sole construction can be included back into
the slidable weight 1204. For example, the cover 1206 may reduce the weight of the
sole construction by 11 grams or more, some or all of which mass that can then be
included at least partially into the weight 1204.
[0064] The cover 1206 can include a projection 1212 extending therefrom that is configured
to engage with a corresponding chamber 1214 within each end of the channel 1202 for
increasing the structural rigidity of the cover 1206 connection as described in the
examples above. In one example, the projection 1212 may be substantially cylindrical
and parallel to a fastener axis 1216. At the opposite side of the cover 1206 from
the fastener 1208, the cover 1206 includes a brace 1218 adjacent to an extended edge
1220 that frictionally engages with the remaining sole 102 of the club head 100 to
secure the edge 1220 to the body 106. In some examples, the brace 1218 may extend
at an angle that is substantially parallel to the fastener axis 1216 so as to guide
the movement of the cover 1206 between the locked and unlocked configurations as described
herein. The brace 1218 may include one or more brackets 1222 for increasing the structural
rigidity of the brace 1218.
[0065] FIG. 32 is a perspective view of the sole 102 of the golf club head 100 with another
weight assembly 1300. Certain components are described above, and thus, are not necessarily
described further. Similar to the example described in FIGS. 30 and 31, the weight
assembly 1300 includes an enlarged cover 1302 that selectively secures a slidable
weight 1304 to one or more portions of the club head 100. In this example, however,
a fastener 1306 is positioned more towards the striking face 108 and adjacent to an
extended edge 1308 of the cover 1302. This example increases the securement of the
edge 1308 to the body 106 of the golf club head 100. In other examples, the fastener
1306 may be positioned at any other location on the cover 1302 as required or desired.
For example, towards the toe side 114, towards the heal side 116, centered on the
cover 1302, etc.
[0066] FIG. 33 is a perspective view of the sole 102 of the golf club head 100 with another
weight assembly 1400. Certain components are described above, and thus, are not necessarily
described further. Similar to the example described in FIGS. 30-32, the weight assembly
1400 includes an enlarged cover 1402 that selectively secures a slidable weight 1404
to one or more portions of the club head 100. In this example, however, the cover
1402 has an extended edge 1406 that is substantially V-shaped. Additionally, the cover
1402 is symmetrical in the toe 114-heel 116 direction. In other examples, the cover
1402 may be asymmetrical in the toe 114 - heel 116 direction as required or desired.
[0067] FIG. 34 is a perspective view of the sole 102 of the golf club head 100 with another
weight assembly 1500. Certain components are described above, and thus, are not necessarily
described further. Similar to the example described in FIGS. 30-33, the weight assembly
1500 includes an enlarged cover 1502 that selectively secures a slidable weight 1504
to one or more portions of the club head 100. In this example, however, the cover
1502 is asymmetrical in the toe side 114 direction. In other examples, the cover 1502
may be asymmetrical in the heel side 116 direction as required or desired.
[0068] FIG. 35 is a perspective view of the sole 102 of the golf club head 100 with another
weight assembly 1600. Certain components are described above, and thus are not necessarily
described further. Similar to the example described in FIGS. 30-34, the weight assembly
1600 includes an enlarged cover 1602 that selectively secures a slidable weight 1604
to one or more portions of the club head 100. In this example, however, the cover
1602 has an extended edge 1606 that is substantially C-shaped. Additionally, the cover
1602 is symmetrical in the toe 114 - heel 116 direction. In other examples, the cover
1602 may be asymmetrical in the toe 114 - heel 116 direction as required or desired.
[0069] FIG. 36 is a perspective view of the sole 102 of the golf club head 100 with another
weight assembly 1700. FIG. 37 is an exploded perspective view of the weight assembly
1700. Certain components are described above, and thus, are not necessarily described
further. Referring concurrently to FIGS. 36 and 37, a recessed channel 1702 is defined
within the sole 102 of the body 106 of the club head 100. The channel 1702 has a substantially
curved shape in the toe 114 - heel 116 direction so that the CG and the MOI of the
club head 100 can be adjusted for fade-draw bias (e.g., the "F" and "D" indicia on
a cover 1706 of the weight assembly 1700). In the example, the curve of the channel
1702 substantially corresponds to the rear outer perimeter of the body 106, where
the sole 102 and the crown 118 are coupled together, and opposite of the striking
face 108. The weight assembly 1700 includes a slidable weight 1704, a cover 1706,
and a fastener 1708.
[0070] In this example, the cover 1706 is substantially U-shaped with a toe end 1710 and
an opposite heel end 1712. The fastener 1708 is coupled to the cover 1706 by a lock
washer 1714 (e.g., a retainer clip) and it is positioned on the inner concave side
of the cover 1706 at approximately a midpoint between the ends 1710, 1712. The fastener
1708 is a threaded bolt that threadingly engages with a nut 1716 formed within the
sole 102 of the body 106. The lock washer 1714 enables the cover 1706 to linearly
move M (e.g., raise and lower) along a fastener axis 1718 (shown in FIG. 38) with
respect to the recessed channel 1702 upon rotation of the fastener 1708. The fastener
1708 is offset from the recessed channel 1702 towards the front and the striking face
108 of the body 106. By offsetting the fastener 1708 from the recessed channel 1702,
the length of the recessed channel 1702 can be extended in the toe-heel direction
so that the weight 1704 can be positioned at a greater number of locations on the
sole 102. Additionally, by positioning the fastener adjacent the inner concave side
of the cover 1706, the weight 1704 is disposed closer to the outer perimeter of the
body 106 so that the weight 1704 increases the adjustability of the CG and MOI of
the club head 100.
[0071] Each end 1710, 1712 of the cover 1706 includes a projection 1720 extending therefrom.
The projections 1720 are sized and shaped to be received within a corresponding chamber
1722 defined at the ends of the recessed channel 1702 and within the sole 102 of the
body 106. The projection 1720 may be substantially cylindrical in shape and increases
the engagement of the cover 1706 with the body 106 so that the weight 1704 is restricted
from moving or rattling when secured within the recessed channel 1702 by the cover
1706. A projection axis 1724 of the projection 1720 (shown in FIG. 38) is substantially
parallel to the fastener axis 1718 so as to facilitate guiding the movement of the
cover 1706 relative to the recessed channel 1702.
[0072] In operation, the weight assembly 1700 is selectively moveable between at least three
configurations to enable the CG and the MOI of the club head 100 to be adjustable.
More specifically, in a first or locked configuration, the cover 1706 is at least
partially disposed within the recessed channel 1702 so that the weight 1704 is secured
within the channel 1702 and movement is restricted. This locked configuration is illustrated
in FIG. 36. When the weight assembly 1700 is in the locked configuration, the projection
1720 is received at least partially within the chamber 1722 and engaged therewith.
By engaging the cover 1706 to the body 106 at its ends 1710, 1712, when the weight
1704 is positioned away from the fastener 1708, the cover 1706 still enables securement
of the weight 1704 within the channel 1702 and reduces or prevents movement of the
weight 1704 in the locked configuration. The locked configuration is used when swinging
the golf club head 100.
[0073] Additionally, the weight assembly 1700 can be positionable into at least two other
configurations that enable the weight 1704 to be selectively slidable with the recessed
channel 1702 and that enable the weight 1704 to be completely removable from the weight
assembly 1700 and the club head 100. In a second or weight moving configuration, the
cover 1706 is partially raised out of the recessed channel 1702 so that the position
of the weight 1704 can be adjusted. However, the weight 1704 is still retained within
the weight assembly 1700 and cannot be completely removed from the club head 100.
This configuration is illustrated in FIG. 40 and described further below. In a third
or weight removal configuration, the cover 1706 is positioned so that the weight 1704
can be completely removed, for example, so that a different weight (e.g., having a
different mass) can be used with the club head 100 so as to adjust the swing weight.
This configuration is illustrated in FIG. 41 and described further below. In each
of the three configurations, however, the cover 1706 remains coupled to the body 106
so that the cover 1706 does not have to be completely removed. In some examples, however,
the weight assembly 1700 may include a fourth configuration (not illustrated), whereby
the cover 1706 is completely removable from the body 106 as required or desired.
[0074] A partial wall 1726 is disposed within the recessed channel 1702. The weight 1704
has a corresponding recess 1728 (shown in FIG. 38) so that the weight 1704 can slide
along the partial wall 1726. The partial wall 1726 at least partially prevents the
weight 1704 from being completely removed when the weight assembly 1700 is in the
weight moving configuration. In some examples, the weight 1704 may include at least
one locating feature 1730 (FIG. 37). The feature 1730 is sized and shaped to engage
with one or more of a plurality of locating lugs 1732 (shown in FIG. 39) that extend
from the cover 1706 when the weight assembly 1700 is in the locked configuration.
The locating lugs 1732 and feature 1730 facilitate locating the weight 1704 at specific
locations within the recessed channel 1702. In the example, the locating lugs 1732
are substantially frustoconical in shape and the locating features 1730 have a corresponding
recessed shape. In other examples, the lugs 1732 and features 1730 can have any other
shape and/or size that enable the cover 1706 and the weight 1704 to function as described
herein.
[0075] FIG. 38 is a cross-sectional view of the weight assembly 1700 taken along line 38-38
in FIG. 36. Certain components are described above, and thus, are not necessarily
described further. As described above, the weight 1704 is secured within the recessed
channel 1702 by the cover 1706. The fastener 1708 positions and secures the cover
1706 to the body 106 of the golf club head, and thus, the fastener 1708 only retains
the weight 1704 indirectly. In some examples, a washer (not shown) may be positioned
on the fastener 1708 and between the body 106 and the cover 1706. The recessed channel
1702 is formed in cross-section by a bottom track wall 1734 and a side wall 1736 arranged
in a substantially L-shape configuration with a corner 1738. In the example, the corner
1738 has an angle that is equal to or less than 90°. In another aspect, the corner
1738 has an angle that less than 90° so that the side wall 1736 is undercut. As such,
when the weight assembly 1700 is in the locked configuration, the cover 1706 wedges
the weight 1704 into the corner 1738 and against the side wall 1736 to frictionally
secure the weight 1704 within the recessed channel 1702 and at least partially underneath
the side wall 1736.
[0076] Adjacent to the corner 1738 and on the bottom track wall 1734, the partial wall 1726
extends in an upward direction and has a height H
1. The weight 1704 has a corresponding recess 1728 that receives at least a portion
of the partial wall 1726. The partial wall 1726 at least partially contains the weight
1704 within the weight assembly 1700 when in the locked and weight sliding configurations.
The weight 1704 also includes a tail 1740 that projects from the recessed channel
1702 and out from underneath the cover 1706. The tail 1740 of the weight 1704 provides
structure for a user to grasp and slide the weight 1704 as required or desired. The
tail 1740 is also visible on the outer surface of the club head so that its position
is easily determined by visual inspection. In this example, the tail 1740 is at least
partially corresponds to the shape of the bottom track wall 1734 of the recessed channel
1702. In other examples, the tail 1740 can have any other size and/or shape as required
or desired.
[0077] FIG. 39 is an inside surface 1742 view of the cover 1706 of the weight assembly 1700
(shown in FIGS. 36-38). The cover 1706 is substantially U-shaped with a concave side
that receives the fastener at an aperture 1744. Proximate the convex side, the inside
surface 1742 has the plurality of locating lugs 1732 that are configured to engage
with the locating feature 1730 within the weight 1704 (shown in FIG. 37). When engaged
(e.g., in the first, locked configuration), the cover 1706 wedges the weight in the
corner of the recessed channel and against the side wall. However, when the cover
1706 raised out of the recessed channel, the locating lugs 1732 disengage from the
weight so that the weight can be moved (e.g., in the weight sliding configuration)
or so that the weight can be completely removed (e.g., in the weight removal configuration).
[0078] Each end 1710, 1712 of the cover 1706 includes the projection 1720 that, in addition
to the fastener, secures the cover 1706 to the body of the club head. In the example,
the projection 1720 engages with the chamber 1722 (shown in FIG. 37) in all three
configurations (e.g., locked, weight moving, and weight removal) of the weight assembly.
Furthermore, the projection 1720 also at least partially defines each of the three
configurations. The projection 1720 is substantially cylindrical in shape and is configured
to extend through the sole of the body and into the interior cavity of the club head
via the chamber 1722. In the example, the projection 1720 includes a plurality of
flexible arms 1746 circumferentially spaced to form the substantially cylindrical
projection 1720. As illustrated, the projection 1720 includes three discrete flexible
arms 1746. In other examples, the projection 1720 may include any other number of
flexible arms 1746 (e.g., 2, 4, 5, etc.) as required or desired.
[0079] FIG. 40 is a cross-sectional view of the weight assembly 1700 taken along line 40-40
in FIG. 36 and in a weight sliding configuration. The projection 1720 has a distal
end 1748 (relative to the inside surface 1742 of the cover 1706) that is formed as
a tapered nose so that the cover 1706 can be press fit into the body 106 of the golf
club head and extend all the way into the interior cavity 122 and through the chamber
1722. For example, the flexible arms 1746 can radially deflect so as to extend through
the chamber 1722 and snap into place. This connection allows the cover 1706 to be
secured to the body 106 and completely removed as required or desired. The cover 1706,
however, does not need to be removed to adjust the weight 1704. The distal end 1748
includes at least one stop 1750 that extends radially outward on the projection 1720.
In the example, the stop 1750 is formed as part of the tapered nose. The projection
1720 also has a proximal end 1752 (relative to the inside surface 1742 of the cover
1706) that is formed as a substantially cylindrical post. The proximal end 1752 frictionally
engages with the chamber 1722 when the cover 1706 is in the locked configuration.
This engagement facilitates the cover 1706 securing the weight 1704 within the recessed
channel 1702 (in addition to the fastener). Additionally, at least one rib 1754 extends
radially on the projection 1720. The rib 1754 is positioned between the distal end
1748 and the proximal end 1752, and offset a distance Di from the stop 1750.
[0080] To move the weight assembly 1700 from the locked configuration (shown in FIG. 36),
when the cover 1706 secures the weight 1704 within the recessed channel 1702, to the
weight moving configuration (shown in FIG. 40) that enables the weight 1704 to slide
within the recessed channel 1702, the threaded fastener 1708 is rotated so that the
cover 1706 raises out of the recessed channel 1702. When the rib 1754 engages with
an end wall 1756 of the chamber 1722, further movement of the cover 1706 is restricted
and the cover 1706 is raised to a height H
2 relative to the body 106 of the club head. As such, the cover 1706 indicates that
the weight assembly 1700 is in the weight moving configuration. To move the weight
assembly 1700 past the weight moving configuration to the weight removal position,
additional force can be induced into the weight assembly 1700 (e.g., via rotation
of the fastener 1708) to overcome the engagement between the rib 1754 and the chamber
1722 until the flexible arm 1746 flexes and the cover 1706 can further raise out of
the recessed channel 1702.
[0081] FIG. 41 is a cross-sectional view of the weight assembly 1700 taken along line 40-40
in FIG. 36 and in a weight removal configuration. Once the engagement of the rib 1754
and the end wall 1756 is forcefully overcome (e.g., via rotation of the fastener 1708
driving movement of the cover 1706), the weight assembly 1700 can move from the weight
moving configuration (shown in FIG. 40) to the weight removal configuration. In the
weight removal configuration, the weight 1704 can be completely removed from the recessed
channel 1702 because the cover 1706 is raised even further out of the recessed channel
1702. When the stop 1750 engages with the end wall 1756 of the chamber 1722, further
movement of the cover 1706 is restricted and the cover 1706 is raised to a height
H
3. The height H
3 is greater than the height H
2 of the prior weight sliding configuration (shown in FIG. 40). As such, the cover
1706 indicates that the weight assembly 1700 is in the weight removal configuration
and the weight 1704 can be completely removed. In some examples, the weight assembly
1700 can be moved past the weight removal configuration and allow the cover 1706 to
be completely removed. If this is the case, additional force is induced into the weight
assembly 1700 to overcome the engagement between the stop 1750 and the chamber 1722
until the flexible arm 1746 flexes and the cover 1706 can be completely removed. In
the example, the stop 1750 is radially larger than the rib 1754, so that the force
required to completely remove the cover 1706 is greater than the force required to
move between the weight moving configuration and the weight removal configuration.
[0082] Because the rib 1754 at least partially defines the weight moving configuration and
the stop 1750 at least partially defines the weight removal configuration, the distance
D
1 (shown in FIG. 40) between the rib 1754 and the stop 1750 defines the height that
the cover 1706 rises between the two different configurations H
2 and H
3. In an aspect, the distance Di may be about five millimeters. Additionally, in an
example, the distance Di may be at least equal to the height H
1 of the partial wall 1726 (shown in FIGS. 37 and 38), so that in the weight removal
configuration, the weight 1704 can be lifted off of the partial wall 1726 and removed
from the weight assembly 1700. In other examples, either the rib 1754 or the stop
1750 may be completely removed from the cover 1706 so that the cover 1706 moves between
only two configurations as required or desired.
[0083] FIG. 42 is a perspective view of a sole 1802 of another golf club head 1800 with
another weight assembly 1804 in a locked configuration. The golf club head 1800 is
a fairway-metal type golf club head having a body 1806 that includes a striking face
1808 with a lower edge 1810 and an upper edge 1812 (shown in FIG. 43), each extending
between a toe 1814 and a heel 1816. The sole 1802 extends from the lower edge 1810
on the bottom side of the club head 1800 and a crown 1818 extends from the upper edge
1812 on the top of the club head 1800. The sole 1802, the striking face 1808, and
the crown 1818 are coupled together so as to define an outer surface 1820 of the body
1806 with an interior cavity 1822 (shown in FIG. 44) formed within. A hosel 1824 is
disposed at the heel 1816 and is configured to couple to a shaft (not shown). The
functions of the components (e.g., sole, striking face, crown, hosel, etc.) of the
fairway-metal type club head 1800 are similar to the component functions described
above in the metalwood-type golf club head examples of FIGS. 1-41. However, fairway-metal
type golf club heads 1800 may strike golf balls directly off the ground surface, thereby
requiring or desiring a substantially smooth outer surface 1820 of the sole 1802 without
any protruding portions. As illustrated in FIG. 42, the club head 1800 is a fairway-metal
type club head, however, the body 1806 may form any type club head, such as an iron-type
club head, hybrid-type club head, or metalwood-type club head (e.g., examples illustrated
in FIGS. 1-41), as required or desired. Furthermore, the features of the weight assembly
1804 described below can additionally or alternatively be utilized in any type club
head described herein as required or desired.
[0084] In this example, a recessed channel 1826 is defined within the sole 1802 of the body
1806 of the club head 1800. The channel 1826 extends in the toe 1814- heel 1816 direction
so that the CG and the MOI of the club head 1800 can be adjusted for fade-draw bias
(e.g., the "F" and "D" indicia on a cover 1830 of the weight assembly 1804). The weight
assembly 1804 includes a slidable weight 1828 disposed at least partially within the
channel 1826, a cover 1830 that extends at least partially over the channel 1826,
and a fastener 1832 configured to couple the cover 1830 to the body 1806. The fastener
1832 retains the weight 1828 in the recessed channel 1826 indirectly via the cover
1830 so that the weight 1828 can be used to adjust the CG and the MOI of the club
head 1800. In this example, the weight assembly 1804 and the recessed channel 1826
are located at a frontal section of the golf club head 1800. By "frontal section,"
it is meant that the weight 1828 is closer to the striking face 1808 than the rearmost
outer perimeter of the body 1806, where the sole 1802 and the crown 1818 are coupled
together farthest from the striking face 1808.
[0085] As illustrated in FIG. 42, the weight assembly 1804 is in a locked configuration
with the cover 1830 at least partially disposed within the recessed channel 1826,
and the weight 1828 secured within the channel 1826 and movement is restricted. When
the cover 1830 and weight assembly 1804 are in the locked configuration, the weight
1828 is completely disposed within the channel 1826 and no portion of the weight 1828
extends above the outer surface 1820 of the body 1806. Additionally, the cover 1830
has an exterior surface 1834 that when the cover 1830 and weight assembly 1804 are
in the locked configuration, the exterior surface 1834 of the cover 1830 aligns with
the outer surface 1820 of the body 1806 and no portion of the cover 1830 extends above
the outer surface 1820 of the body 1806. Because the weight assembly 1804 is completely
disposed within the recessed channel 1826 and at least aligned with, or below, the
outer surface 1820 of the body 1806, the smoothness of the outer surface 1820 of the
club head 1800 is maintained so as to promote good ground interaction.
[0086] FIG. 43 is a perspective view of the sole 1802 of the golf club head 1800 with the
weight assembly 1804 in an unlocked configuration. Certain components are described
above, and thus, are not necessarily described further. Via rotation of the fastener
1832, the cover 1830 can be raised at least partially out of the recessed channel
1826 and into the unlocked configuration. In the unlocked configuration, the weight
1828 is selectively slidable within the channel 1826 so as to adjust the CG and the
MOI as required or desired. In this example, the weight 1828 is engaged with the cover
1830 so that the weight 1828 moves with the cover 1830 between the unlocked configuration
and the locked configuration and raises at least partially out of the recessed channel
1826 when in the unlocked configuration. It should be appreciated, that while FIGS.
42 and 43 illustrate and describe the weight assembly 1804 in two different configurations,
a locked configuration and an unlocked configuration, the weight assembly 1804 could
be moveable between more than two configurations as required or desired. For example,
the weight assembly 1804 can move between at least three configurations, a locked
configuration, a weight moving configuration, and a weight removal configuration,
as described above in reference to FIGS. 36-41.
[0087] FIG. 44 is a cross-sectional view of the golf club head 1800 with the weight assembly
1804 taken along line 44-44 in FIG. 42. FIG. 45 is a partial perspective cross-sectional
view of the weight assembly 1804 taken along line 44-44 in FIG. 42. Referring concurrently
to FIGS. 44 and 45, certain components are described above, and thus, are not necessarily
described further. The fastener 1832 is a threaded bolt that threadingly engages with
a nut 1836 formed within the sole 1802 of the body 1806. The fastener 1832 is coupled
to the cover 1830 by a lock washer 1838 so that linear movement (e.g., via rotation
of the fastener 1832) is transferred to the cover 1830 and the cover 1830 can move
in and out of the recessed channel 1826 as described herein.
[0088] In this example, the channel 1826 is defined by a bottom track 1840 and two opposing
sidewalls 1842, 1844. A first sidewall 1842 is adjacent the striking face 1808 and
a second sidewall 1844 is adjacent to the rear of the sole 1802. The cover 1830 is
substantially L-shaped with a long leg 1846 and a short leg 1848. The short leg 1848
includes a portion that couples to the fastener 1832 and both the short leg 1848 and
the fastener 1832 are positioned adjacent the second sidewall 1844. The short leg
1848 also includes a flange 1850. The weight 1828 includes a groove 1852 that is sized
and shaped to receive the flange 1850. The weight 1828 is slidably engaged with the
cover 1830 and with the flange 1850 received at least partially within the groove
1852. This engagement between the cover 1830 and the weight 1828 enables the weight
1828 to move (e.g., raise out and lower back into the channel 1826) with the cover
1830 between the locked configuration (shown in FIG. 42) and the unlocked configuration
(shown in FIG. 43), while also enabling the weight 1828 to slide relative to the cover
1830 in the toe-heel direction when the weight assembly is in the unlocked configuration.
When the cover 1830 is in the locked configuration, the long leg 1846 also substantially
covers the weight 1828 so as to increase the smoothness of the outer surface 1820
of the club head 1800.
[0089] The bottom track 1840 includes a plurality of bosses 1854 extending into the channel
1826. In this example, there are three bosses 1854, each which corresponds respectively
to a fade bias position of the weight 1828, a draw bias position of the weight 1828,
and a center-neutral position of the weight 1828. Additionally, the first sidewall
1842 includes a plurality of dimples 1856 that correspond to the plurality of bosses
1854. The weight 1828 includes a hollow 1858 that is sized and shaped to receive the
boss 1854 and a position indicator 1860 that is sized and shaped to be received within
the dimple 1856. In operation, when the weight assembly 1804 is in the unlocked configuration
(shown in FIG. 43), the weight 1828 is raised above the bosses 1854 so that it can
be selectively moved between the bosses 1854 and the dimples 1856 of the channel 1826.
Once the weight 1828 is positioned, the weight assembly 1804 can be moved to the locked
configuration (shown in FIG. 42) and the selected boss 1854 is received at least partially
within the hollow 1858 of the weight 1828, and the position indicator 1860 is received
at least partially within the selected dimple 1856.
[0090] In this example, at least a portion of the position indicator 1860 of the weight
1828 is visible on the outer surface 1820 of the club head 1800, when the weight assembly
1804 is in the locked configuration. This allows the user to easily visually verify
the position of the weight 1828 on the club head 1800. It should be appreciated that
while three bosses 1854 and dimples 1856 are illustrated and described, any other
number of bosses and dimples locating features may be provided to define the position
of the weight 1828 within the recessed channel 1826. For example, five sets of bosses
and dimples may be provided. Additionally, the position indicator 1860 has a cutout
so that when the cover 1830 is raised to the unlocked configuration (shown in FIG.
43), the position indicator 1860 can slide completely out of the dimple 1856 and move
above the first sidewall 1842 to adjust the position of the weight 1828.
[0091] The cover 1830 can also include one or more projections 1862 that are sized and shaped
to be received within a corresponding chamber 1864 of the recessed channel 1826. The
projections 1862 are configured to increase the engagement of the cover 1830 with
the body 1806 so that the weight 1828 is restricted from moving or rattling when secured
within the recessed channel 1826 by the cover 1830. In some examples, the projections
1862 may be similar to the projections described above in reference to FIGS. 36-41
and include one or more flexible arms, a tapered nose, a stop, and at least one rib.
[0092] FIG. 46 is a bottom view of the golf club head 1800 with another weight assembly
1900. FIG. 47 is a perspective cross-section view of the golf club head 1800 with
the weight assembly 1900 taken along line 47-47 in FIG. 46. Referring concurrently
to FIGS. 46 and 47, certain components are described above, and thus, are not necessarily
described further. Similar to the example described in FIGS. 42-45, the weight assembly
1900 includes a cover 1902 that selectively secures a slidable weight 1904 within
a recessed channel 1906. The weight 1904 is engaged with the cover 1902 so that the
weight 1904 moves with the cover 1902 between two or more configurations. In this
example, however, the cover 1902 completely covers the weight 1904 within the channel
1906, when the cover 1902 is in a locked configuration. The cover 1902 can be formed
from an at least partially transparent material so that the position of the weight
1904 is visible to the user.
[0093] FIG. 48 is a perspective view of another golf club head 2000. FIG. 49 is a bottom
view of the club head 2000 with another weight assembly 2002. Referring concurrently
to FIGS. 48 and 49, the golf club head 2000 is an iron-type golf club head that includes
a striking face 2004 configured to strike a golf ball. The striking face 2004 is connected
to a top line portion 2006, a toe portion 2008, and a heel portion 2010. The toe portion
2008 and the heel portion 2010 are also at least in part connected to the top line
portion 2006. The heel portion 2010 is connected to a hosel 2012 that is configured
to couple to a shaft (not shown). The striking face 2004 is also connected to a sole
2014. The golf club head 2000 also includes a back portion 2016 that is attached at
least partially to the sole 2014, the top line portion 2006, the toe portion 2008,
and the heel portion 2010.
[0094] The components of the golf club head 2000, such as the striking face 2004, the top
line portion 2006, the toe portion 2008, the heel portion 2010, and the back portion
2016 may be of a metallic material, such as a steel. The components of the golf club
head 2000 may be formed through a casting process. Some of the components may be cast
as a single piece and the remainder of the components may be attached subsequent to
the casting process. For instance, the sole 2014, the top line portion 2006, the toe
portion 2008, the heel portion 2010, and the back portion 2016 may be cast as a single
piece. The striking face 2004 may then be attached to that single piece via welding
or any other suitable process for attaching two club head components to one another.
In such an example, the striking face 2004 may be an insert.
[0095] In operation, the sole 2014 generally provides the lower surface of the club head
2000 when the club head 2000 is placed in an address position. The club head 2000
defines a center of gravity (CG) and a moment of inertia (MOI) that impact flight
characteristics of the golf ball when hit with the striking face 2004. The weight
assembly 2002 is coupled to the club head 2000 such that the CG and/or the MOI of
the club head 2000 can be selectively adjusted as required or desired. In this example,
the weight assembly 2002 includes a movable weight 2018, a cover 2020 configured to
secure the weight 2018 in place, and a fastener 2022 for coupling the weight assembly
2002 to one or more portions of the club head 2000. A recessed elongated channel 2024
is formed in the sole 2014 of the club head 2000 and is sized and shaped to receive
at least a portion of the weight 2018. Similar to the examples described above, the
fastener 2022 is adapted to retain the weight 2018 in the channel 2024 only indirectly
by the cover 2020. Additionally, the cover 2020 can be loosened or completely removed,
via the fastener 2022, to enable the weight 2018 to slide within the channel 2024
and selectively adjust the CG and the MOI as required or desired.
[0096] In this example, the fastener 2022 is positioned at the toe end of the weight assembly
2002 and aligned with the channel 2024. In other examples, the fastener 2022 may be
positioned at the heel end of the weight assembly 2002 as required or desired.
[0097] FIG. 50 is a cross-section view of another weight assembly 2100. FIG. 51 is a schematic
view of the weight assembly 2100. Referring concurrently to FIGS. 50 and 51, a recessed
channel 2102 is defined within a body 2104 of a club head (e.g., club heads 100, 1800,
and/or 2000 described above). The weight assembly 2100 includes a slidable weight
2106 and a cover 2108. A fastener (not shown) is used to retain the weight 2106 within
the channel 2102. In this example, the cover 2108 includes an inside surface 2110
that engages with at least a portion of the weight 2106, when the weight 2106 is secured
within the channel 2102. In this example, at least a portion of the inside surface
2110 of the cover 2108 includes a friction material liner 2112. The friction material
2112 is configured to frictionally engage with the weight 2106 when the cover 2108
is in a locked configuration. By frictionally engaging the weight 2106 with the cover
2108, the weight 2106 is secured within the channel 2102 while reducing or preventing
the weight 2106 from rattling therein. In the example, the friction material can be
a soft metal material, such as brass.
[0098] The friction material 2112 may include a plurality of grooves 2114 on the mating
surface with the weight 2106. In this example, the grooves 2114 may be triangular
in shape, although, other shapes are also contemplated herein. When a clamp load 2116
is applied to the friction material 2112, the material yields to hold the weight 2106
in place (as shown in FIG. 51) and match the particular surface combination of the
channel 2102, weight 2106, and cover 2108. Once the deformation takes place and contact
stress is established, the friction material 2112 will not deform further. By frictionally
engaging the weight 2106 with the cover 2108, the weight 2106 can be positioned at
any location within the channel 2102 and indexing features do not need to be included.
Additionally, by removing the indexing features, the weight 2106 and channel 2102
have more substantially flat surfaces, which increases manufacturing efficiencies.
[0099] In this example, the cover 2108 may also include one or more protruding notches 2118
that engage with a corresponding cavities 2120 within the body 2104. The notches 2118
may be substantially circular in shape. The notches 2118 and cavities 2120 are described
further below in reference to FIGS. 52 and 53. It should be appreciated that while
the friction material 2112 is illustrated as being coupled to the cover 2108, the
friction material 2112 can additionally or alternatively be coupled to the weight
2106.
[0100] FIG. 52 is a top view of the cover 2108 of the weight assembly 2100 (shown in FIG.
50). FIG. 53 is a side view of the cover 2108. Referring concurrently to FIGS. 52
and 53 certain components are described above, and thus, are not necessarily described
further. The cover 2108 includes a plurality of protruding notches 2118 that engage
with corresponding cavities 2120 within the body 2104. By engaging the cover 2108
at a plurality of locations, the cover 2108 is restricted or prevented from bowing
out of alignment with the outer surface of the body 2104 when securing the weight.
As illustrated in FIG. 53, the side cavities may be tapered so as to accept the cover
1206 sliding in at an angle.
[0101] FIG. 54 is a bottom view of another golf club head 2200 with another weight assembly
2202 in a locked configuration. The golf club head 2200 includes a body 2204 having
a sole 2206, and with the weight assembly 2202 disposed on the sole 2206. The body
2204 also includes a striking face and a crown (both not shown), such that the body
2204 has an outer surface 2208. In an aspect, the golf club head 2200 can be a fairway-metal
type golf club head, however, the body 2204 can form any type club head, such as an
iron-type club head, hybrid-type club head, or driver or other metal-wood type club
head (e.g., one or more of the examples illustrated in FIGS. 1-53). Additionally,
the functions of the components (e.g., sole, striking face, crown, hosel, etc.) of
the club head 2200 are similar to the component functions described above in FIGS.
1-53. Furthermore, the features of the weight assembly 2202 described below can additionally
or alternatively be utilized in any type club head described herein, and as required
or desired.
[0102] In this example, a recessed channel 2210 is defined within the sole 2206 of the body
2204 of the club head 2200. The recessed channel 2210 extends in a toe-heel direction
so that the CG and MOI of the club head 2200 can be adjusted (e.g., for fade-draw
bias). The weight assembly 2202 includes a slidable weight 2212 disposed at least
partially within the channel 2210, a cover 2214 that extends at least partially over
the channel 2210, and a fastener 2216 configured to couple the cover 2214 to the body
2204. The fastener 2216 retains the weight 2212 in the recessed channel 2210 indirectly
via the cover 2214 so that the weight 2212 can be used to adjust the CG and MOI of
the club head 2200.
[0103] As illustrated in FIG. 54, the weight assembly 2202 is in a locked configuration
with the cover 2214 at least partially disposed within the recessed channel 2210 and
the weight 2212 secured within the channel 2210 so as to restrict movement. When the
cover 2214 and the weight assembly 2202 are in the locked configuration, at least
a portion of the weight 2212 is visible between the body 2204 and the cover 2214.
This configuration enables the user to more easily determine the placement of the
weight 2212 within the recessed channel 2210. The weight assembly 2202 can also be
moved into an unlocked configuration as described herein. For example, via rotation
of the fastener 2216, the cover 2214 can be raised at least partially out of the recessed
channel 2210 and enable the weight 2212 to be repositioned.
[0104] In this example, the weight 2212 overlaps and engages with the cover 2214 so that
both move together between the locked configuration and the unlocked configuration.
Furthermore, this engagement is such that the weight 2212 is reduced or prevented
from twisting and tilting relative to the cover 2214 when raising and lowering with
respect to the recessed channel 2210. As such, the weight 2212 is prevented from binding
within the recessed channel 2210 during weight adjustment, and thereby, increasing
performance of the weight assembly 2202.
[0105] FIG. 55 is a perspective, cross-sectional, view of the weight assembly 2202 taken
along line 54-54 in FIG. 54. FIG. 56 is a cross-sectional view of the cover 2214 taken
along line 54-54 in FIG. 54. Referring concurrently to FIGS. 55 and 56, the cover
2214 has a shelf 2218 that is configured to slidably engage with the weight 2212.
In the example, the shelf 2218 is open in a direction that faces towards the striking
face of the club head and away from the fastener 2216. Additionally, the shelf 2218
extends within the cover 2214 in a toe-heel direction. It is appreciated, however,
that the shelf 2218 can be defined within the cover 2214 in any other orientation
and/or direction as required or desired to achieve the adjustable weight functionality
as described herein. When the cover 2214 is in the unlocked position, the weight 2212
is raised relative to the club head such that the weight 2212 is selectively slidable
within the shelf 2218 and the recessed channel 2210 (shown in FIG. 54). Conversely,
when the cover 2214 is in the locked position, the weight 2212 is disposed at least
partially within the recessed channel 2210 and the shelf 2218, and secured therein,
so as to restrict or prevent movement of the weight 2212. In the example, the shelf
2218 provides an overlap for the cover 2214 with the weight 2212 so as to reduce the
weight 2212 from binding within the recessed channel.
[0106] The shelf 2218 includes an outer wall 2220 and an opposite inner wall 2222. As described
herein, the outer wall and inner wall of the shelf 2218 are in reference to the interior
cavity of the body 2204 of the club head (shown in FIG. 54). As such, the outer wall
2220 is disposed proximate an exterior surface 2224 of the cover 2214. The weight
2212 is configured to be slidably received at least partially between the outer wall
2220 and the inner wall 2222 of the shelf 2218 and against an inner wall 2226 of the
shelf 2218. The three walls of the shelf 2218 retain the weight 2212 within the cover
2214 so that the position of the weight 2212 is restricted or prevented from tilting
relative to the cover 2214 when being moved between the locked configuration and unlocked
configuration. This configuration restricts the weight 2212 from binding within the
weight assembly 2202, and thus, increases performance of the weight assembly 2202.
[0107] In the example, this position of the weight 2212 within the cover 2214 can be measured
by a tilt angle 2228 that is defined as an angular position of the weight 2212 relative
to the outer wall 2220 of the shelf 2218. In an aspect, the tilt angle 2228 is substantially
the same in both the unlocked configuration and the locked configuration. In another
aspect, the tilt angle 2228 is substantially parallel to the outer wall 2220 of the
shelf 2218 in both the unlocked configuration and the locked configuration. The weight
2212 has an outer surface 2230 that is positioned directly against the outer wall
2220, the inner wall 2222, and the inner wall 2226 of the cover 2214 when received
within the shelf 2218. As such, the outer surface 2230 of the weight 2212 maintains
its position directly against the walls of the shelf 2218 in both the unlocked configuration
and locked configuration.
[0108] The weight 2212 includes a position indicator 2232 that extends at least partially
out of the shelf 2218. The position indicator 2232 can be used to selectively slide
the weight 2212 when the weight assembly 2202 is in the unlocked configuration. When
in the locked configuration, the position indicator 2232 is visible between the cover
2214 and the body of club head so that the user can easily determine the weight characteristics
of the club head. Additionally, the position indicator 2232 can be disposed within
dimples (e.g., the dimples 1856 shown in FIG. 45) of the recessed channel. The weight
2212 also includes a hollow 2234 that is sized and shaped to receive a boss (e.g.,
the boss 1854 shown in FIG. 45) of the recessed channel. In the example, the hollow
2234 is disposed adjacent the inner wall 2222 of the shelf 2218.
[0109] The cover 2214 can also include one or more projections 2236 that are sized and shaped
to be received within a corresponding chamber (not shown) of the recessed channel.
The projection 2236 is configured to increase the engagement of the cover 2214 with
the golf club head body so that the weight 2212 is restricted from moving or rattling
when secured within the recessed channel by the cover 2214. The projection 2236 can
also be used to limit the extraction of the cover 2214 from the body 2204 (shown in
FIG. 54) to create a soft stop before completely unscrewing and extracting the cover
2214 from the body. In some examples, the projection 2236 may be similar to the projections
described above in reference to FIGS. 36-41 and include one or more flexible arms,
a tapered nose, a stop, and at least one rib.
[0110] In the example, a width 2238 of the outer wall 2220 relative to the inner wall 2226
is greater than a width 2240 of the inner wall 2222. This configuration enables the
weight 2212 to be retained within the shelf 2218 without tilting and binding up within
the weight assembly 2202. Additionally, the weight 2212 includes the hollow 2234 and
the position indicator 2232 that can extend out from the shelf 2218 and enable the
function of the weight assembly 2202 as described herein. For example, the inner wall
2226 enables the hollow 2234 of the weight 2212 to engage with corresponding structure
within the recessed channel. In an aspect, the width of the outer wall is between
approximately 2 to 4 times greater than the width of the inner wall. In another aspect,
a ratio of the width 2238 of the outer wall 2220 to the width 2240 of the inner wall
2222 is greater than, or equal to, 2:1. In yet another aspect, the ratio of the width
2238 of the outer wall 2220 to the width 2240 of the inner wall 2222 is greater than,
or equal to, 3:1. In still another aspect, the ratio of the width 2238 of the outer
wall 2220 to the width 2240 of the inner wall 2222 is between approximately 2:1 and
4:1. It should be appreciated that other ratio values are also contemplated herein
and may not be expressly listed above.
[0111] FIG. 57 is a perspective view of the weight 2212. FIG. 58 is a schematic top plan
view of the weight 2212. Referring concurrently to FIGS. 57 and 58, as well as FIG.
54, at least a portion of the weight 2212 is exposed and visible between the exterior
surface of the cover 2214 and the outer surface 2208 of the body 2204, when the weight
assembly 2202 in the locked configuration. That is, a gap is formed at least partially
between a portion of the cover 2214 and the body 2204, and the weight 2212 at least
partially fills this gap. For example, the position indicator 2232 may be exposed
and visible on the golf club head 2200. This configuration enables the position of
the weight 2212 to be easily determined. However, the weight 2212 is not entirely
exposed and visible. By reducing the portions of the weight 2212 exposed on the golf
club head 2200, the smoothness between the outer surface 1820 of the club head 2200
and the cover 2214 is increased. As such, the golf club head 2200 has increased performance
(e.g., striking golf balls directly off the ground surface, aerodynamic performance,
etc.), while also including the weight adjustable function via the weight assembly
2202 as described herein.
[0112] In the example, between approximately 0% and 30% of the weight 2212 is exposed and
visible between the outer surface 2208 of the body 2204 and the exterior surface of
the cover 2214 in the locked configuration. In an aspect, between approximately 10%
and 20% of the weight 2212 is exposed between the outer surface 2208 of the body 2204
and the exterior surface of the cover 2214 in the locked configuration. In yet another
aspect, approximately 16% of the weight 2212 is exposed. It should be appreciated
that other percentage values are also contemplated herein and may not be expressly
listed above. Although not shown in the figures, the weight 2212 can be completely
invisible without departing from the scope and content of the present invention.
[0113] With reference to FIG. 57, the percentage of the weight 2212 visible and exposed
(e.g., portion 2242) may be based on the outer surface area 2230 of the weight 2212.
As used herein, the outer surface 2230 of the weight 2212 includes more than one side
of the weight shape and the entire outer perimeter as illustrated in FIG. 57. For
example, in an aspect, between approximately 0% and 30% of the outer surface 2230
of the weight 2212 is exposed between the outer surface 2208 of the body 2204 and
the exterior surface of the cover 2214 in the locked configuration. In another aspect,
between approximately 10% and 20% of the outer surface 2230 of the weight 2212 is
exposed between the outer surface 2208 of the body 2204 and the exterior surface of
the cover 2214 in the locked configuration. In yet another aspect, approximately 16%
of the outer surface 2230 the weight 2212 is exposed. It should be appreciated that
other percentage values are also contemplated herein and may not be expressly listed
above.
[0114] With reference to FIG. 58, the percentage of the weight 2212 visible and exposed
(e.g., portion 2244) may be based on a planar surface area 2246 of the weight 2212.
As used herein, the planar surface area 2246 is the surface area only on one projection
side of the weight shape (e.g., top planar area). While the top planar area is illustrated
in FIG. 58, other weight sides (e.g., right planar area, left planar area, etc.) are
also contemplated herein. For example, in an aspect, between approximately 0% and
30% of the planar surface area 2246 of the weight 2212 is exposed between the outer
surface 2208 of the body 2204 and the exterior surface of the cover 2214 in the locked
configuration. In another aspect, between approximately 10% and 20% of the planar
surface area 2246 of the weight 2212 is exposed between the outer surface 2208 of
the body 2204 and the exterior surface of the cover 2214 in the locked configuration.
In yet another aspect, approximately 16% of the planar surface area 2246 the weight
2212 is exposed. It should be appreciated that other percentage values are also contemplated
herein and may not be expressly listed above.
[0115] FIG. 59 is a schematic perspective view of an exemplary test mule 2300 with another
weight assembly 2302. FIG. 60 is a cross-sectional view of the weight assembly 2302
taken along line 60-60 in FIG. 59. FIG. 61 is another cross-sectional view of the
weight assembly 2302 taken along line 61-61 in FIG. 59. Referring concurrently to
FIGS. 59-61, the test mule 2300 represents a golf club head as described herein and
can be utilized to test and develop features of the weight assembly 2302 as required
or desired. The club head that the test mule 2300 represents can be any type of club
head described herein as required or desired, such as, but not limited to, a metalwood-type
golf club head, a fairway-metal type club head, an iron-type club head, or a hybrid-type
club head. In an aspect, the club head that the test mule 2300 represents is a metalwood-type
club head with a striking face, a sole extending from a lower edge of the striking
face, and a crown extending from an upper edge of the striking face (all three components
not shown in FIGS. 59-60). In an aspect, a transition area where the sole and the
crown couple together opposite the striking face is known as a skirt of the club head,
and the weight assembly 2302 is disposed at least partially on the skirt. As such,
the weight assembly 2302 is disposed at a rear perimeter of the club head and proximate
where the sole and the crown couple together. In an aspect, the weight assembly 2302
is disposed substantially at a rear portion of the club head opposite the striking
face. One example of a weight assembly disposed on a skirt of a golf club head is
shown in FIG. 8 and described above. In the example, the test mule 2300 includes a
body 2304 having an outer surface 2306 that represents the body of the club head.
Additionally, a bracket 2307 is coupled to the body 2304 to facilitate testing and
development, and the bracket 2307 is not representative of the club head. In an aspect,
the bracket 2307 is substantially triangular in shape.
[0116] In this example, a recessed channel 2308 is defined in the outer surface 2306 of
the body 2304. The channel 2308 extends along a curve in a generally toe-heel direction
so that the CG and the MOI of the club head can be adjusted via the weight assembly
2302. The weight assembly 2302 includes a weight 2310 disposed at least partially
within the channel 2308 and configured to slide therein, a cover 2312 that extends
at least partially over the channel 2308, and a fastener 2314 configured to couple
the cover 2312 to the body 2304. The fastener 2314 is configured to retain the weight
2310 in the recessed channel 2308 indirectly via the cover 2312 and so that the weight
2310 can be used to adjust the CG and the MOI of the club head.
[0117] Similar to the examples described above, the weight assembly 2302 is configured to
move between at least a locked configuration, shown in FIGS. 59 and 61, and an unlocked
configuration, shown in FIG. 60. In the locked configuration, the cover 2312 is at
least partially disposed within the recessed channel 2308, and the weight 2310 is
secured within the channel 2308 with movement restricted. In the unlocked configuration,
the fastener 2314 enables the cover 2312 to move along a fastener axis so that the
weight 2310 can slide relative to cover 2312 and the body 2304. In an aspect, from
the locked configuration, the fastener 2314 may be rotatable between about 2-3 turns
to release the cover 2312 from the locked configuration and enable the weight 2310
to slide at least partially within the recessed channel 2308. In another aspect, the
fastener 2314 may rotate about 2½ turns to enable the weight 2310 to slide within
the weight assembly 2302.
[0118] The cover 2312 has a first end 2316 and an opposite second end 2318. The fastener
2314 is coupled to the first end 2316 (e.g., via a lock washer) of the cover 2312
and so that the fastener 2314 is used for attaching the cover 2312 to the body 2304.
The second end 2318 of the cover 2312 includes a projection 2320. The projection 2320
of the second end 2318 is configured to engage with a corresponding chamber 2322 defined
at the end of the recessed channel 2308. In the locked configuration, the fastener
2314 secures the first end 2316 of the cover 2312 to the body 2304, while the projection
2320 of the second end 2318 engages with the chamber 2322 of the channel 2308 so that
a position of the weight 2310 within the recessed channel 2308 is retained between
the first end 2316 and the second end 2318 of the cover 2312. When the weight assembly
2302 is moved towards the unlocked configuration, the fastener 2314 is used to move
the cover 2312 along the fastener axis and raise the cover 2312 at least partially
out of the recessed channel 2308. This configuration enables the weight 2310 to slide
and be repositioned on the body 2304 of the golf club head. In this example, the projection
2320 extends in a direction that is substantially parallel to the fastener axis so
that the cover 2312 can uniformly raise out of the recessed channel 2308. In an aspect,
the chamber 2322 is formed as an undercut in a sidewall of the recessed channel 2308,
and this undercut engages with the projection 2320 of the cover 2312. The fastener
2314 is at the opposite end of the undercut.
[0119] To assist in positioning the weight 2310 at preselected positions within the recessed
channel 2308, the cover 2312 includes at least one locating lug 2324 that extends
from an inner surface of the cover 2312. The weight 2310 includes a corresponding
hollow 2326 shaped and sized to receive at least a portion of the locating lug 2324.
As illustrated in FIG. 60, the cover 2312 has three spaced apart locating lugs 2324
so that the hollow 2326 can selectively engage the lug 2324 at three discrete locations
within the recessed channel 2308. In an aspect, the locating lug 2324 may not be symmetrical,
for example, one side of the lug 2324 can have a steeper angled side than an opposite
more shallower angle side. Furthermore, in this example, the weight 2310 has a first
inclined surface 2332 on one end and a second inclined surface 2334 on the opposite
end proximate the side of the hollow 2326. The first and second inclined surfaces
2332, 2334 are different and configured to engage with one of the steeper or shallower
angled sides of the locating lug 2324. This configuration allows for the weight 2310
to be positioned between two locating lugs 2324 and selectively engage therewith.
As such and as illustrated in FIG. 60, the weight 2310 can engage with the cover 2312
at two more discrete locations within the recessed channel 2308 and between pairs
of locating lugs 2324. When the locating lug(s) 2324 is engaged with the weight 2310,
the weight 2310 is retained more tightly within the cover 2312 to reduce or prevent
rattling and further movement of the weight 2310 in the locked configuration. Additionally,
one or more of the locating lugs 2324 can define a position of the weight 2310 on
the golf club head. In other aspects, the cover 2312 can have five spaced apart locating
lugs 2324. Other numbers of locating lugs 2324 are also contemplated herein. It should
also be appreciated that in other examples, a locating lug 2324 may be provided for
every discrete location of the weight 2310 as required or desired.
[0120] In this example, the weight 2310 is slidably engaged with the body 2304 within the
recessed channel 2308. The body 2304 includes a partial wall 2328 that is disposed
within the recessed channel 2308. The partial wall 2328 extends from a bottom of the
recessed channel 2308, and the weight 2310 includes a recess 2330 shaped and sized
to receive at least a portion of the partial wall 2328. By slidably engaging the partial
wall 2328 and the recess 2330 of the weight 2310, the weight 2310 does not move with
the cover 2312 when the cover is moved towards the unlocked configuration. This retention
of the weight 2310 within the recessed channel 2308 enables the locating lugs 2324
of the cover 2312 to disengage with the weight 2310 and allow the weight 2310 to slide
and change positions. Additionally, the orientation of the weight 2310 within the
recessed channel 2308 can be held by the partial wall 2328 when the cover 2312 is
in the unlocked configuration so that the weight 2310 can slide more easily to different
positions.
[0121] FIG. 62 is a schematic perspective view of another test mule 2400 with another weight
assembly 2402. FIGS. 63A-E are cross-sectional views of the weight assembly 2402 taken
along line 63-63 in FIG. 62 and with a weight 2410 in a variety of different positions.
FIG. 64 is another cross-sectional view of the weight assembly 2402 taken along line
64-64 in FIG. 62. Referring concurrently to FIGS. 62-64, and similar to the example
described above in FIGS. 59-61, the test mule 2400 represents a club head that can
be any type of club head described herein as required or desired, and in an aspect,
the weight assembly 2402 is disposed on a skirt of the club head and at a rear perimeter
where the sole and the crown couple together. The test mule 2400 includes a body 2404
having an outer surface 2406 that represents the club head and a bracket 2407. A recessed
channel 2408 is defined in the outer surface 2406 of the body 2404. The weight assembly
2402 includes the weight 2410 disposed at least partially within the channel 2408
and configured to slide therein, a cover 2412 that extends at least partially over
the channel 2408, and a fastener 2414 configured to couple the cover 2412 to the body
2404. The cover 2412 has a first end 2416 and an opposite second end 2418. The fastener
2414 is coupled to the first end 2416 (e.g., via a lock washer) of the cover 2412
and so that the fastener 2414 is used for attaching the cover 2412 to the body 2404.
The second end 2418 of the cover 2412 includes a projection 2420. The projection 2420
of the second end 2418 is configured to engage with a corresponding chamber 2422 defined
at the end of the recessed channel 2408 and to secure the second end 2418 to the body
2404.
[0122] In this example, to assist in positioning the weight 2410 at preselected positions
within the recessed channel 2408, the body 2404 includes at least one locating lug
2424 disposed within the recessed channel 2408. In an aspect, the locating lug 2424
extends from a back wall of the recessed channel 2408 relative to the outer surface
2406. In another aspect, the locating lug 2424 is substantially symmetrical with two
similarly angled sides. The weight 2410 includes a corresponding hollow 2426 shaped
and sized to receive at least a portion of the locating lug 2424. Furthermore, in
this example, the weight 2410 has inclined surfaces 2432 on each end proximate the
side of the hollow 2426. The inclined surfaces 2432 are similar to each other and
configured to engage with the angled sides of the locating lugs 2424. As illustrated
in FIGS. 63 A-E, the cover 2412 has three spaced apart locating lugs 2424 so that
the weight 2410 is selectively positionable at five discrete locations within the
recessed channel 2408. Other numbers of locating lugs 2424 are also contemplated herein.
The locating lugs 2424 are not evenly spaced apart in the heel-toe direction of the
club head and have two different spacing distances. In the example, the locating lug
2424 proximate the fastener 2414 is spaced further apart from the locating lug 2424
in the middle than the locating lug 2424 proximate the projection 2420. In an aspect,
the spacing between the fastener locating lug 2424 and the middle locating lug 2424
is approximately double the spacing between the projection locating lug 2424 and the
middle locating lug 2424. Additionally, in some examples, the locating lugs 2424 can
be substantially cone-shaped.
[0123] Starting with FIG. 63A, the weight 2410 is disposed adjacent to the fastener 2414
and the hollow 2426 is engaged with the locating lug 2424 proximate the fastener 2414.
As such, a portion of the weight 2410 is positioned on both sides of locating lug
2424. The weight assembly 2402 is in a locked configuration so that the position of
the weight 2410 relative to the body 2404 is secured. In some aspects, the far side
of the weight 2410 can be positioned directly against a portion of an end wall of
the recessed channel 2408 and/or a portion of the cover 2412 that couples to the fastener
2414. Moving next to FIG. 63B, the weight assembly 2402 can be moved to an unlocked
configuration (e.g., at least partially raising the cover 2412 out of the recessed
channel 2408 to enable sliding movement of the weight 2410) for repositioning the
weight 2410 and adjusting the CG and/or MOI of the club head. Once the weight 2410
is repositioned, the weight assembly 2402 can be moved into the locked configuration
(as shown) to secure the position of the weight 2410. In this position, the weight
2410 is disposed between two locating lugs 2424 such that the hollow 2426 does not
have a locating lug 2424 received therein. Rather, the inclined surfaces 2432 are
engaged with a respective locating lug 2424.
[0124] In FIG. 63C, the hollow 2426 of the weight 2410 is engaged with the locating lug
2424 in the middle. In this position, one of the inclined surfaces 2432 is also engaged
with the locating lug 2424 proximate the projection 2420. In FIG. 63D, the hollow
2426 of the weight 2410 is engaged with the locating lug 2424 proximate the projection
2420. In this position, one of the inclined surfaces 2432 is engaged with the locating
lug 2424 in the middle. Lastly, in FIG. 63E, the weight 2410 is disposed adjacent
to the projection 2420 and between the locating lug 2424 and an end wall of the recessed
channel 2408. The hollow 2426 does not have a locating lug 2424 received therein and
one of the inclined surfaces 2432 is engaged with the locating lug 2424 proximate
the projection 2420. In the example, the far side of the weight 2410 can be positioned
directly against a portion of an end wall of the recessed channel 2408 and/or a portion
of the cover 2412 proximate the projection 2420. When the locating lug(s) 2424 is
engaged with the weight 2410, the weight 2410 is retained more tightly within the
recessed channel 2408 to reduce or prevent rattling and further movement of the weight
2410 in the locked configuration. Additionally, one or more of the locating lugs 2424
can define a position of the weight 2410 on the golf club head. In the example, by
shifting the locating lug 2424 proximate the projection 2420 inward, the weight 2410
can more easily slide between all positions without binding. It should be appreciated,
that the spacing of the locating lugs 2424 can take on any other configuration as
required or desired. For example, the recessed channel 2408 can have five spaced apart
locating lugs 2424 such that in each position the hollow 2426 of the weight 2410 engages
with a locating lug 2424. In other examples, three similarly spaced locating lugs
2424 can be used.
[0125] Additionally, the weight 2410 is slidably engaged with the cover 2412. The cover
2412 includes a flange 2428 that extends from an interior of the cover 2412 and the
weight 2410 includes a groove 2430 shaped and sized to receive at least a portion
of the flange 2428. By slidably engaging the flange 2428 and the groove 2430 of the
weight 2410, the weight 2410 is configured to move with the cover 2412 when moved
towards the unlocked configuration. This movement of the weight 2410 enables the weight
2410 to disengage with the locating lugs 2424 and so that the weight 2410 can slide
and change positions.
[0126] FIG. 65 is a partial perspective view of an exemplary recessed channel 2500 within
a body 2502 of a test mule. FIG. 66 is another partial perspective view of the recessed
channel 2500. Referring concurrently to FIGS. 65 and 66, the body 2502 is illustrated
schematically and the test mule represents a club head that can be any type of club
head described herein as required or desired. The recessed channel 2500 is configured
to receive a slidable weight 2504 and a cover (not shown) is configured to selectively
retain the weight 2504 in different positions. The cover is coupled to the body 2502
with a fastener (not shown) that defines a fastener axis. The recessed channel 2500
includes a chamber 2506 that is sized and shaped to receive a corresponding projection
(not shown) of the cover. The chamber 2506 is defined on the opposite end of the recessed
channel 2500 from the fastener location so that both ends of the cover are engaged
with the body 2502 and increase the retention of the weight 2504.
[0127] In this example, the recessed channel 2500 includes a lip 2508 proximate the chamber
2506. The lip 2508 extends into the recessed channel 2500 and is configured to engage
with the cover at a corresponding duct (not shown). As such, when the cover is moved
towards an unlocked configuration that allows the weight 2504 to slide within the
recessed channel 2500, the end of the cover opposite the fastener remains at least
partially engaged with the body 2502 to reduce or prevent the end of the cover from
becoming loose relative to the body 2502. The lip 2508 is elongated in a direction
that is substantially parallel to the fastener axis to enable movement of the cover
as described herein. The lip 2508 can be positioned at a top wall of the recessed
channel 2500, as illustrated in FIG. 65, at a bottom wall of the recessed channel
2500, as illustrated in FIG. 66, or both.
[0128] FIG. 67 is a schematic perspective view of another test mule 2600 with another weight
assembly 2602. FIG. 68 is a cross-sectional view of the weight assembly 2602 in a
first configuration taken along line 67-67 in FIG. 67. FIG. 69 is a cross-sectional
view of the weight assembly 2602 in a second configuration taken along line 67-67
in FIG. 67. Referring concurrently to FIGS. 67-69, and similar to the examples described
above in FIGS. 59-64, the test mule 2600 represents a club head that can be any type
of club head described herein as required or desired, and in an aspect, the weight
assembly 2602 is disposed on a skirt of the club head and at a rear perimeter where
the sole and the crown couple together. The test mule 2600 includes a body 2604 having
an outer surface 2606 that represents the club head and a bracket 2607. A recessed
channel 2608 is defined in the outer surface 2606 of the body 2604. In this example,
however, the weight assembly 2602 includes a cover 2610 that is configured to be selectively
oriented within the recessed channel 2608 and secured to the body 2604 to at least
partially define a weight position of the club head and to adjust the CG and the MOI
of the club head.
[0129] In this example, the weight assembly 2602 includes the cover 2610 that is removably
coupled to the body 2604 and at least partially within the recessed channel 2608.
The cover 2610 has a first end 2612 and an opposite second end 2614. A fastener 2616
is mounted (e.g., via a lock washer) on the first end 2612 of the cover 2610 and is
configured to couple to the body 2604. Additionally, a first weight 2618 is disposed
at the first end 2612 of the cover 2610. In this example, the first weight 2618 defines
the first end 2612 of the cover 2610 itself and is removable from the second end 2614
of the cover 2610 so that different mass weights 2618 are interchangeable and can
form the cover 2610 as required or desired. The second end 2614 of the cover 2610
includes a projection 2620 extending therefrom.
[0130] Each end of the recessed channel 2608 has a chamber 2622 and a fastener receiver
2624. The chamber 2622 is configured to engage with the projection 2620 of the cover
2610 and the fastener 2616 is configured to couple to the fastener receiver 2624.
By having the recessed channel 2608 symmetrical at each end, the cover 2610 can be
selectively coupled to the body 2604 so that the first weight 2618 can be oriented
in either the first configuration (shown in FIG. 68) or the second configuration (shown
in FIG. 69). In the first configuration, the first end 2612 of the cover 2610 is disposed
on the heel side of the club head so that the first weight 2618 is positioned towards
the heel side of the body 2604. In this configuration, the fastener 2616 is secured
to the fastener receiver 2624 on the heel side and the projection 2620 of the cover
2610 engages with the chamber 2622 at the toe side. This leaves the fastener receiver
2624 on the toe side and the chamber 2622 on the heel side unused by the cover 2610.
Conversely, in the second configuration, the first end 2612 of the cover 2610 is disposed
on the toe side of the club head so that the first weight 2618 is positioned towards
the toe side of the body 2604. In this configuration, the fastener 2616 is secured
to the fastener receiver 2624 on the toe side and the projection 2620 of the cover
2610 engages with the chamber 2622 at the heel side. This leaves the fastener receiver
2624 on the heel side and the chamber 2622 on the toe side unused by the cover 2610.
In this example, the cover 2610 has a dog-bone type shape so that is position within
the recessed channel 2608 can be switched as required or desired.
[0131] Additionally or alternatively, a second weight 2626 may be coupled to a corresponding
weight chamber 2628 defined in the body 2604 and within the recessed channel 2608.
The weight chamber 2628 is positioned at both ends of the recessed channel 2608 proximate
the fastener receiver 2624 and is covered by the cover 2610 when coupled to the body
2604. As such, the second weight 2626 is secured by the cover 2610 within the weight
chamber 2628 and indirectly retained by the fastener 2616 of the weight assembly 2602.
In an aspect, the second weight 2626 may thread at least partially into the weight
chamber 2628. It should be appreciated that the position and use of the second weight
2626 does not necessarily need to correspond to the orientation of the cover 2610
and as illustrated in FIGS. 68 and 69. For example, the second weight 2626 can be
used opposite of the first weight 2618 and retained at least partially by the second
end 2614 of the cover 2610. In another example, only the first weight 2618 and no
second weight 2626 can be utilized. In still another example, a pair of second weights
2626 may be used in the pair of weight chambers 2628. By using more than one weight
2618, 2626 the CG and the MOI of the club head can be more finely tuned as required
or desired.
[0132] FIG. 70 is a schematic perspective view of another test mule 2700 with another weight
assembly 2702. FIG. 71 is a partial cross-sectional view of the weight assembly 2702
in an unlocked configuration. FIG. 72 is a partial cross-sectional view of the weight
assembly 2702 in a locked configuration. Referring concurrently to FIGS. 70-72, and
similar to the examples described above in FIGS. 59-64 and 67-69, the test mule 2700
represents a club head that can be any type of club head described herein as required
or desired, and in an aspect, the weight assembly 2702 is disposed on a skirt of the
club head and at a rear perimeter where the sole and the crown couple together. The
test mule 2700 includes a body 2704 having an outer surface 2706 that represents the
club head. A recessed channel 2708 is defined in the outer surface 2706 of the body
2704. In this example, however, the weight assembly 2702 includes a cover 2710 that
is pivotably coupled to the body 2704 and a slidable weight 2712 to adjust the CG
and the MOI of the club head. In an aspect, the cover 2710 is lighter in density than
the weight 2712 so that a larger amount of mass can be used to manipulate the CG and
the MOI.
[0133] In this example, the cover 2710 has a first end 2714 and an opposite second end 2716.
A fastener 2718 is mounted on the first end 2714 of the cover 2710 (e.g., via a lock
washer) and is configured to secure the first end 2714 to the body 2704 of the club
head. The second end 2716 of the cover 2710 is pivotably coupled to the body 2704.
The weight 2712 is slidably coupled to the cover 2710 and is movable between the first
end 2714 and the second end 2716. In operation, the cover 2710 is pivotable about
its second end 2716 between at least a locked configuration and an unlocked configuration
(shown in FIG. 70). In the locked configuration, the fastener 2718 secures the first
end 2714 of the cover 2710 to the body 2704 and the weight 2712 is disposed at least
partially within the recessed channel 2708 and retained therein by the cover 2710.
The position of the weight 2712 within the recessed channel 2708 between the first
end 2714 and the second end 2716 of the cover 2710 is thereby retained indirectly
by the fastener 2718. In the unlocked configuration, the first end 2714 of the cover
2710 pivots out of the recessed channel 2708 to enable the weight 2712 to be repositioned
(e.g., slide along the cover 2710) as required or desired. The unlocked configuration
is illustrated in FIG. 70 and the weight 2712 moves with the cover 2710.
[0134] The second end 2716 of the cover 2710 can include a hook 2720 that pivotably engages
with a post 2722 in the body 2704. The hook 2720 includes a hard stop 2724 that is
configured to engage with the body 2704 in the unlocked position so as to define the
pivot limit of the cover 2710. The hard stop 2724 can be tapered on one end so that
the second end 2716 of the cover 2710 is more easily inserted into the body 2704 during
assembly. In other example, the second end 2716 of the cover 2710 can be pivotably
coupled to the body 2704 with a pin connection (not shown). The recessed channel 2708
can include one or more locating lugs 2726 to assist in positioning the weight 2712
as required or desired. In aspects, the weight 2712 can be positionable in two, four,
or six discrete positions at least partially defined by the locating lugs 2726. In
this example, the weight 2712 is slidably engaged with the cover 2710 and pivots therewith.
In other examples, the weight can be slidably engaged with the body so that it does
not pivot with the cover. This example is described below in reference to FIG. 73.
[0135] FIG. 73 is a cross-sectional view of another weight assembly 2750 that can be used
with the test mule 2700 (shown in FIG. 70). In this example, the weight assembly 2750
includes a pivotable cover 2752 and a slidable weight 2754. However, in this example,
the weight 2754 is slidably engaged at least partially within the recessed channel
2708 of the body 2704 so that the weight 2754 does not pivot with the cover 2752.
The weight assembly 2750 includes a rail 2756 that secures the weight 2754 to the
body 2704 while still enabling the weight 2754 to slide. In the locked configuration
as illustrated in FIG. 73, the cover 2752 secures the position of the weight 2754
relative to the body 2704 via the rail 2756.
[0136] FIG. 74 is an exploded perspective view of another test mule 2800 with another weight
assembly 2802. Similar to the examples described above in FIGS. 59-64 and 67-72, the
test mule 2800 represents a club head that can be any type of club head described
herein as required or desired, and in an aspect, the weight assembly 2802 is disposed
on a skirt of the club head and at a rear perimeter where the sole and the crown couple
together. The test mule 2800 includes a body 2804 having an outer surface 2806 that
represents the club head and a bracket 2807. A recessed channel 2808 is defined in
the outer surface 2806 of the body 2804. In this example, however, the weight assembly
2802 includes a cover 2810 that is coupled to the body 2804 via a fastener 2812 that
is disposed proximate a center of the cover 2810. The cover 2810 is configured to
secure a slidable weight 2814 while enabling a position of the weight 2814 to be selectively
adjusted. The weight 2814 has an elongated U-shape so as to accommodate the center
mounted fastener 2812 and a portion of the weight 2814 can be disposed on both sides
of the fastener 2812. The cover 2810 has projections 2816 at each end to engage with
the recessed channel 2808. The recessed channel 2808 includes locating lugs 2818 to
assist in positioning the weight 2814 and dimples 2820 that receive at least a portion
of a position indicator 2822 of the weight 2814.
[0137] FIG. 75 is a perspective view of a sole 2902 of another golf club head 2900 with
another weight assembly 2904. FIG. 76 is a cross-sectional view of the weight assembly
2904 taken along line 76-76 in FIG. 75. FIG. 77 is a cross-sectional view of the weight
assembly 2904 taken along line 77-77 in FIG. 75. Referring concurrently to FIGS. 75-77,
the golf club head 2900 is a metalwood-type golf club head having a body 2906 that
includes a striking face 2908 with a lower edge 2910 and an upper edge (not shown)
extending between a toe 2912 and a heel 2914. The sole 2902 extends from the lower
edge 2910 on the bottom side of the club head 2900 and a crown 2916 extends from the
upper edge on the top of the club head 2900. The sole 2902, the striking face 2908,
and the crown 2916 are coupled together so as to define an outer surface 2918 of the
body 2906 with an interior cavity 2920 formed within. A hosel 2922 is disposed at
the heel 2914 and is configured to couple to a shaft (not shown). The functions of
the components (e.g., sole, striking face, crown, hosel, etc.) of the metalwood-type
club head 2900 are similar to the component functions described above. The body 2906
may form any type club head, such as a fairway-metal type club head, an iron-type
club head, or a hybrid-type club head as required or desired. Furthermore, the features
of the weight assembly 2904 described below can additionally or alternatively be utilized
in any type club head described herein as required or desired.
[0138] In this example, a recessed channel 2924 is defined within the sole 2902 of the body
2906 of the club head 2900. The channel 2924 extends in the toe 2912 - heel 2914 direction
so that the CG and the MOI of the club head 2900 can be adjusted for fade-draw bias.
In an aspect, the recessed channel 2924 may be defined in a transition area where
the sole 2902 and the crown 2916 couple together opposite the striking face 2908 and
known as a skirt of the club head 2900. As such, the recessed channel 2924 and the
weight assembly 2904 are disposed at a rear perimeter of the club head 2900 and proximate
where the sole 2902 and the crown 2916 couple together. In an aspect, the recessed
channel 2924 and the weight assembly 2904 are disposed substantially at a rear perimeter
portion of the club head 2900 opposite the striking face 2908.
[0139] The weight assembly 2904 includes a slidable weight 2926 disposed at least partially
within the recessed channel 2924 and configured to slide therein, a cover 2928 that
extends at least partially over the channel 2924 and adapted to releasably secure
the weight 2926 within the recessed channel 2924, and a fastener 2930 configured to
couple the cover 2928 to the body 2906. The fastener 2930 retains the weight 2926
in the recessed channel 2924 indirectly via the cover 2928 and so that the weight
2926 can be used to adjust the CG and the MOI of the club head. Similar to the examples
described above, the weight assembly 2904 is configured to move between at least a
locked configuration, shown in FIG. 79 and described further below, and an unlocked
configuration, shown in FIG. 80 and described further below. In the locked configuration,
the cover 2928 is at least partially disposed within the recessed channel 2924, and
the weight 2926 is secured within the channel 2924 with its movement restricted. In
the unlocked configuration, the fastener 2930 enables the cover 2928 to move along
a fastener axis 2932 so that the weight 2926 is released and can slide relative to
cover 2928 and the body 2906. Additionally, in this example, the cover 2928 can also
at least partially rotate relative to the recessed channel 2924 and the body 2906
towards a weight removal configuration, shown in FIG. 81 and described further below.
[0140] The body 2906 includes a partial wall 2934 that is disposed within the recessed channel
2924. The partial wall 2934 extends from a bottom of the recessed channel 2924, and
the weight 2926 includes a recess 2936 shaped and sized to receive at least a portion
of the partial wall 2934. By slidably engaging the partial wall 2934 and the recess
2936 of the weight 2926, the weight 2926 does not move with the cover 2928 when the
cover is moved towards the unlocked configuration. To assist in positioning the weight
2926 at preselected positions within the recessed channel 2924, the cover 2928 includes
at least one locating lug 2938 that extends from an inner surface of the cover 2928.
The weight 2926 includes a corresponding hollow 2940 shaped and sized to receive at
least a portion of the locating lug 2938. As such, when the weight 2926 is engaged
with the cover 2928, the weight 2926 is retained more tightly within the cover 2928
to reduce or prevent rattling and further movement of the weight 2926 in the locked
configuration. In the example, the inner surface of the cover 2928 includes an oblique
surface 2942 that is configured to engage with a corresponding oblique surface 2944
on the weight 2926. The oblique surfaces 2942, 2944 taper in a direction such that
their height above the bottom wall of the recessed channel 2924 is larger and increases
along a direction that is away from the partial wall 2934. This configuration urges
the weight 2926 in a direction towards the top wall of the recessed channel 2924 and
induces a compression force on the weight 2926 between the cover 2928 and the recessed
channel 2924 for securing the weight 2926 therein.
[0141] In this example, the cover 2928 is formed from a first portion 2946 and a second
portion 2948. The fastener 2930 engages with the first portion 2946 via a lock-washer
(not shown) such that the entire cover 2928 is linearly moveable along the fastener
axis 2932. The second portion 2948 has a first end 2950 that is rotatably coupled
to the first portion 2946 and an opposite second end 2952 that has a projection 2954.
Similar to the other examples described herein, the projection 2954 is configured
to engage with a corresponding chamber 2956 defined in the body 2906 and within the
recessed channel 2924, so that when the weight assembly 2904 is in the locked configuration,
the second end 2952 more tightly secures the weight 2926 within the recessed channel
2924. By enabling the second portion 2948 of the cover 2928 to rotate relative to
the first portion 2946 when the second end 2952 is not engaged with the recessed channel
2924, access to the weight 2926 is increased and allows for the weight 2926 to be
completely removed from the club head 2900 as required or desired and as illustrated
in FIG. 81.
[0142] FIG. 78 is an exploded view of the cover 2928 of the weight assembly 2904 (shown
in FIGS. 75-77). The cover 2928 includes the first portion 2946 that couples to the
fastener 2930 and the second portion 2948. In the example, the first portion 2946
and the second portion 2948 may be discrete and separable from one another. In other
examples, the first portion 2946 and the second portion 2948 may be fixed to each
other, while still being rotatable relative to one another. The first portion 2946
has a first end 2958 with a bore that is shaped and sized to receive and couple to
the fastener 2930. The bore extends in a direction along the fastener axis 2932. The
first portion 2946 also has an opposite second end 2960 that is configured to rotatably
couple to the second portion 2948. The second end 2960 has a cylinder 2962 that is
spaced away from the first end 2958 and that extends in a direction that is substantially
orthogonal to the fastener axis 2932. The cylinder 2962 rotatably engages the second
portion 2948 and defines a rotation axis for the second portion 2948 to rotate relative
to the first portion 2946.
[0143] The second portion 2948 extends between the first end 2950 and the second end 2952.
The first end 2950 has a hook 2964 that rotatably engages with the cylinder 2962 of
the first portion 2946 such that the rotation axis of the second portion 2948 is substantially
orthogonal to the fastener axis 2932. In an aspect, an outer surface 2966 of the hook
2964 is rounded so that the second portion 2948 can rotate around the cylinder 2962.
The hook 2964 is formed at least partially by an arm 2968 that is elongated and engages
with a sidewall of the bore of the first portion 2946 so that rotation of the second
portion 2948 is partially limited. This configuration allows the second portion 2948
to move with the first portion 2946 when the first portion 2946 linearly moves along
the fastener axis 2932. In some examples, the hook 2964 can snap-fit around the cylinder
2962 so that in order to separate the two portions 2946, 2948, a separation force
is required. The second end 2952 of the second portion 2948 includes the projection
2954. Extending between the first end 2950 and the second end 2952 of the second portion
2948, a cutout 2970 is formed that is sized and shaped to at least partially receive
the weight 2926 (shown in FIGS. 76 and 77). Within the cutout 2970, the locating lugs
2938 and the oblique surface 2942 of the cover 2928 are formed.
[0144] FIG. 79 is a perspective view of the weight assembly 2904 in a locked configuration.
In the locked configuration, the fastener 2930 is tightened to the body 2906 of the
club head so that the cover 2928 is engaged to the body 2906 and at least partially
within the recessed channel 2924 to secure a position of the weight 2926 within the
recessed channel 2924. In the locked configuration, the fastener 2930 retains the
weight 2926 in the recessed channel 2924 indirectly via the cover 2928. The first
end of the first portion 2946 of the cover 2928 is secured to the body 2906 by the
fastener 2930. The second end of the second portion 2948 of the cover 2928 is secured
to the body 2906 via the projection 2954 (shown in FIG. 78) such that rotation of
the second portion 2948 relative to the first portion 2946 is prevented. Between the
first portion 2946 and the second portion 2948, the hook 2964 and cylinder 2962 (shown
in FIG. 78) engagement restricts the portions 2946, 2948 from separating from one
another in the locked configuration. In order to release the weight 2926 from its
secured position, the fastener 2930 is used to move the weight assembly 2904 towards
the unlocked configuration described below in reference to FIG. 80.
[0145] FIG. 80 is a perspective view of the weight assembly 2904 in an unlocked configuration.
In the unlocked configuration, the fastener 2930 is loosened with respect to the body
2906 of the club head. When the fastener 2930 is loosened, the cover 2928 linearly
moves along the fastener axis 2932 (shown in FIG. 78) and at least partially raises
out of the recessed channel 2924. In the unlocked configuration, the cover 2928 releases
the weight 2926 so that the weight 2926 may slide within the recessed channel 2924.
The first end of the first portion 2946 of the cover 2928 remains secured to the body
2906 by the fastener 2930 in the unlocked configuration.
[0146] In some examples, the second end of the second portion 2948 of the cover 2928 can
remain partially engaged to the body 2906 via the projection 2954 (shown in FIG. 78)
in the unlocked configuration so that rotation of the second portion 2948 relative
to the first portion 2946 remains restricted and the weight 2926 cannot be removed
from the recessed channel 2924. However, the weight 2926 is still enabled to slide
and be repositioned as required or desired. In this example, to disengage the projection
2954 from the recessed channel 2924, the fastener 2930 is used to further raise the
cover 2928 along the fastener axis 2932 so as to position the cover 2928 in a weight
removal configuration as described below in reference to FIG. 81. In other examples,
in the unlocked configuration the cover 2928 is raised such that the projection 2954
is disengaged from the recessed channel 2924 without any further movement along the
fastener axis 2932. In this example, the cover 2928 is positioned such that it can
be moved towards a weight removal configuration without further movement via the fastener
2930 as described below in reference to FIG. 81.
[0147] FIG. 81 is a perspective view of the weight assembly 2904 in a weight removal configuration.
In the weight removal configuration, the first portion 2946 of the cover 2928 is raised
at least partially out of the recessed channel 2924 such that the projection 2954
of the second portion 2948 is disengaged from the chamber 2956 defined within the
recessed channel 2924. This disengagement enables the second portion 2948 of the cover
2928 to open towards the weight removal configuration by rotating relative to the
first portion 2946 and in an outwards direction relative to the body 2906 of the club
head. The fastener 2930 does not need to be used to open the second portion 2948 of
the cover 2928. The rotation of the second portion 2948 is around a rotation axis
that is substantially orthogonal to the fastener axis 2932 (shown in FIG. 78). By
opening the cover 2928 the weight 2926 can be completely removed from the recessed
channel 2924 as required or desired. Additionally, when the second portion 2948 is
rotated relative to the first portion 2946 of the cover 2928, the hook 2964 and cylinder
2962 engagement (shown in FIG. 78) restricts the portions 2946, 2948 from separating
from one another in the weight removal configuration.
[0148] FIG. 82 is a perspective view of a sole 3002 of another golf club head 3000 with
another weight assembly 3004. FIG. 83 is a cross-sectional view of the weight assembly
3004 taken along line 83-83 in FIG. 82. Referring concurrently to FIGS. 82 and 83,
the golf club head 3000 includes a body 3006, a striking face 3008, a lower edge 3010,
an upper edge (not shown), a toe 3012, a heel 3014, a crown 3016, an outer surface
3018, an interior cavity 3020, and a hosel 3022, the functions of which are similar
to the component functions described above. The body 3006 may form any type club head
as described herein, such as, a metalwood-type club head, a fairway-metal type club
head, an iron-type club head, or a hybrid-type club head as required or desired. Furthermore,
the features of the weight assembly 3004 described below can additionally or alternatively
be utilized in any type club head described herein as required or desired.
[0149] In this example, a recessed channel 3024 is defined within the sole 3002, and/or
a transition area (e.g., skirt) where the sole 3002 and the crown 3016 couple together.
The channel 3024 extends in the toe 3012 - heel 3014 direction so that the CG and
the MOI of the club head 3000 can be adjusted for fade-draw bias. In an aspect, the
recessed channel 3024 and the weight assembly 3004 are disposed substantially at a
rear perimeter portion of the club head 3000 opposite the striking face 3008.
[0150] The weight assembly 3004 includes a slidable weight 3026 disposed at least partially
within the recessed channel 3024 and configured to slide therein, a cover 3028 that
extends at least partially over the channel 3024 and adapted to releasably secure
the weight 3026 within the recessed channel 3024, and a fastener 3030 configured to
couple the cover 3028 to the body 3006. Similar to the examples described above, the
weight assembly 3004 is configured to move between at least a locked configuration,
shown in FIG. 85 and described further below, and an unlocked configuration, shown
in FIG. 86 and described further below. In the locked configuration, the cover 3028
is at least partially disposed within the recessed channel 3024, and the weight 3026
is secured within the channel 3024 with its movement restricted. In the unlocked configuration,
the fastener 3030 enables the cover 3028 to move along a fastener axis 3032 so that
the weight 3026 can slide relative to cover 3028 and the body 3006. Additionally,
in this example, the cover 3028 can also at least partially rotate relative to the
recessed channel 3024 and the body 3006 towards a weight removal configuration, shown
in FIG. 87 and described further below. Additionally, the body 3006 includes a partial
wall 3034 that slidably engages the weight 3026 and the cover 3028 includes at least
one locating lug 3036 to facilitate positioning of the weight 3026.
[0151] FIG. 84 is a perspective view of the cover 3028 of the weight assembly 3004 (shown
in FIGS. 82 and 83). With continued reference to FIG. 83, the cover 3028 has a first
end 3038 and an opposite second end 3040. The second end 3040 has a projection 3042,
which similar to the other examples herein, the projection 3042 is configured to engage
with a corresponding chamber 3044 defined in the body 3006 and within the recessed
channel 3024. As such, when the weight assembly 3004 is in the locked configuration,
the second end 3040 more tightly secures the weight 3026 to the body 3006. In some
examples, a duct 3046 is defined in the cover 3028 that is configured to engage with
a corresponding lip (not shown) that extends from the recessed channel 3024. This
duct and lip feature facilitates the sliding engagement of the second end 3040 of
the cover 3028 with the recessed channel 3024 within the body 3006 and as described
further above in reference to FIGS. 65 and 66. The first end 3038 of the cover 3028
engages with an enlarged head 3048 of the fastener 3030 and the fastener 3030 is freely
rotatable relative to the cover 3028. In this example, the fastener 3030 is not coupled
to the cover 3028 with a lock-washer, and the fastener 3030 is devoid of a lock-washer.
[0152] The first end 3038 of the cover 3028 has a holder 3050 defined on an inner surface
of the cover 3028 that is shaped and sized to receive the enlarged head 3048 of the
fastener 3030. The holder 3050 has an inner surface 3052 that is larger than the enlarged
head 3048 so that the enlarged head 3048 is freely rotatable within the holder 3050.
In the example, the inner surface 3052 has a first sidewall 3054 that is substantially
parallel to the fastener axis 3032 and an opposite second sidewall 3056 that is tapered
relative to the fastener axis 3032. In an aspect, the second sidewall 3056 is oriented
so as to increase the gap between the first sidewall 3054 and the second sidewall
3056 in a direction that is towards an outer surface of the cover 3028. When the fastener
3030 is tightened to or loosened from the body 3006 of the club head, the enlarged
head 3048 is positioned against the first sidewall 3054 of the inner surface 3052,
as illustrated in FIG. 83. This configuration aligns cover 3028 along the fastener
axis 3032 so that the cover 3028 can linearly move along the fastener axis 3032 and
engage or disengage the projection 3042 relative to the chamber 3044. However, when
the fastener 3030 is loosened from the body 3006 (e.g., the enlarged head 3048 raised
from the body 3006 along the fastener axis 3032) and the cover 3028 is disengaged
from the body 3006, the second end 3040 of the cover 3028 can also be angled away
from the body 3006 via the orientation of the second sidewall 3056. This movement
of the cover 3028 enables the cover 3028 to at least partially rotate around the fastener
axis 3032 towards a weight removal configuration as illustrated in FIG. 87 and described
further below.
[0153] The inner surface 3052 of the holder 3050 also includes an outer axial wall 3058
that is substantially orthogonal to the fastener axis 3032. The outer axial wall 3058
confines the enlarged head 3048 within the holder 3050 in an axial direction along
the fastener axis 3032 so that when the enlarged head 3048 is loosened and raised
relative to the body 3006 of the club head, corresponding linear movement is induced
on the cover 3028 even without use of a lock-washer. The outer axial wall 3058 can
include an aperture 3060 so that a tool (not shown) can access the enlarged head 3048.
In an aspect, the aperture 3060 has a diameter that is less than a diameter of the
enlarged head 3048. An opposite inner axial wall 3062 is configured to at least partially
hook around the enlarged head 3048 so that when the enlarged head 3048 is tightened
and lowered relative to the body 3006, corresponding linear movement is induced on
the cover 3028 even without use of a lock-washer. Additionally, the holder 3050 is
a protruding component of the cover 3028 (e.g., via the inner axial wall 3062) with
an outer surface 3064 that extends at least partially circumferentially around the
fastener axis 3032. As such, the outer surface 3064 is curved and at least partially
cylindrical in shape. In an aspect, the outer surface 3064 is curved and extends at
least 180° around the fastener axis 3032. The outer surface 3064 facilitates rotation
of the cover 3028 relative to the body 3006, when the cover 3028 is at least partially
raised out of the recessed channel 3024.
[0154] In the example, the holder 3050 is accessible from either the top or bottom of the
cover 3028 and allows the fastener 3030 to be at least partially inserted into the
holder 3050 (e.g., the enlarged head 3048). When the cover 3028 is coupled to the
body 3006 via the fastener 3030 and at least partially inserted within the recessed
channel 3024, the holder 3050 is at least partially inserted within the recessed channel
3024 because it is a protruding feature so that the cover 3028 is restricted or prevented
from being decoupled from the enlarged head 3048 without completely withdrawing the
holder 3050 from the recessed channel 3024.
[0155] FIG. 85 is a perspective view of the weight assembly 3004 in a locked configuration.
In the locked configuration, the fastener 3030 is tightened to the body 3006 of the
club head so that the cover 3028 is engaged to the body 3006 and at least partially
within the recessed channel 3024 to secure a position of the weight 3026 within the
recessed channel 3024. In the locked configuration, the fastener 3030 retains the
weight 3026 in the recessed channel 3024 indirectly via the cover 3028. The first
end of the cover 3028 is secured to the body 3006 by the fastener 3030. The second
end of the cover 3028 is secured to the body 3006 via the projection 3042 (shown in
FIG. 83) such that rotation of the cover 3028 is prevented. In order to release the
weight 3026 from its secured position, the fastener 3030 via access by the aperture
3060 is used to move the weight assembly 3004 towards the unlocked configuration described
below in reference to FIG. 86.
[0156] FIG. 86 is a perspective view of the weight assembly 3004 in an unlocked configuration.
In the unlocked configuration, the fastener 3030 is loosened with respect to the body
3006 of the club head. When the fastener 3030 is loosened, the cover 3028 linearly
moves along the fastener axis 3032 (shown in FIG. 83) and at least partially raises
out of the recessed channel 3024 by the fastener head engaging with the outer axial
wall of the holder 3050. In the unlocked configuration, the cover 3028 releases the
weight 3026 so that the weight 3026 may slide within the recessed channel 3024. The
first end of the cover 3028 remains secured to the body 3006 by the fastener 3030
in the unlocked configuration.
[0157] In some examples, the second end of the cover 3028 can remain partially engaged to
the body 3006 via the projection 3042 in the unlocked configuration so that rotation
of the cover 3028 remains restricted and the weight 3026 cannot be removed from the
recessed channel 3024. However, the weight 3026 is still enabled to slide and be repositioned
as required or desired. In this example, to disengage the projection 3042 from the
recessed channel 3024, the fastener 3030 is used to further raise the cover 3028 along
the fastener axis 3032 so as to position the cover 3028 in a weight removal configuration
as described below in reference to FIG. 87. In other examples, in the unlocked configuration
the cover 3028 is raised such that the projection 3042 is disengaged from the recessed
channel 3024 without any further movement along the fastener axis 3032. In this example,
the cover 3028 is positioned such that it can be moved towards a weight removal configuration
without further movement via the fastener 3030 as described below in reference to
FIG. 87.
[0158] FIG. 87 is a perspective view of the weight assembly 3004 in a weight removal configuration.
In the weight removal configuration, the first end 3038 of the cover 3028 is raised
at least partially out of the recessed channel 3024 such that the projection 3042
of the second end 3040 is disengaged from the chamber 3044 defined within the recessed
channel 3024. This disengagement enables the second end 3040 of the cover 3028 to
be opened towards the weight removal configuration by angling away from the body 3006
of the club head and rotating it around the fastener axis of the fastener 3030. For
example, the fastener head is positioned against the second sidewall 3056 (shown in
FIG. 83) to angle the second end 3040 away from the body 3006 and the second end 3040
can be rotated around the fastener 3030. By opening the cover 3028, the weight 3026
can be completely removed from the recessed channel 3024 as required or desired. Additionally,
the holder 3050 (shown in FIG. 83) of the fastener 3030 is still at least partially
projecting into the recessed channel 3024 so that the cover 3028 cannot be completely
removed from the body 3006 of the club head without further movement of the fastener
3030. This configuration enables both the cover 3028 and the fastener 3030 to remain
coupled to the body 3006 in the weight removal configuration.
[0159] FIG. 88 is a perspective view of a sole 3102 of another golf club head 3100 with
another weight assembly 3104. The golf club head 3100 includes a body 3106, a striking
face 3108, a lower edge 3110, an upper edge (not shown), a toe (not shown), a heel
3112, a crown 3114, an outer surface 3116, an interior cavity (not shown), and a hosel
3118, the functions of which are similar to the component functions described above.
The body 3106 may form any type club head as described herein, such as, a metalwood-type
club head, a fairway-metal type club head, an iron-type club head, or a hybrid-type
club head as required or desired. Furthermore, the features of the weight assembly
3104 described below can additionally or alternatively be utilized in any type club
head described herein as required or desired.
[0160] In this example, a channel 3120 is defined by the body 3106 and the channel 3120
is a through-opening that extends through the body 3106 between a toe-side opening
3122 and a heel-side opening 3124. In some examples, the channel 3120 may be separated
from the interior cavity of the body 3106 by a channel wall. In other examples, the
channel 3120 may be at least partially open into the interior cavity of the body 3106.
The channel 3120 may be disposed within the sole 3102, and/or a transition area where
the sole 3102 and the crown 3114 couple together (e.g., skirt). The channel 3120 extends
in the toe-heel direction so that the CG and the MOI of the club head 3100 can be
adjusted for fade-draw bias. In an aspect, the channel openings 3122, 3124 are disposed
substantially at a rear perimeter portion of the club head 3100 opposite the striking
face 3108 and a front-rear centerline of the club head 3100.
[0161] The weight assembly 3104 includes a slidable weight 3126 slidably engaged with a
cover 3128 and a fastener 3130 configured to couple the cover 3128 to the body 3106.
The cover 3128 has a first end 3132 and an opposite second end 3134. The fastener
3130 is coupled to the first end 3132 (e.g., via a lock-washer) and the cover 3128
extends in a direction that is along the fastener axis. Both the first end 3132 and
the second end 3134 of the cover 3128 have an outer surface that is shaped and sized
to align with and not extend from the outer surface 3116 of the club head 3100 when
secured thereto. Similar to the examples described above, the weight assembly 3104
is configured to move between at least a locked configuration (not illustrated) and
an unlocked configuration (shown in FIG. 88). In the locked configuration, the cover
3128 inserted within the channel 3120 so that the weight 3126 is completely disposed
within the channel 3120 and within the body 3106 of the club head 3100. The position
of the weight 3126 on the cover 3128 is secured within the channel 3120 when the weight
assembly 3104 is in the locked configuration. As such, the fastener 3130 retains the
weight 3126 in the channel 3120 indirectly via the cover 3128. In the unlocked configuration,
the fastener 3130 enables the cover 3128 to be at least partially withdrawn from the
channel 3120 and along the fastener axis so that the weight 3126 is at least partially
extracted from the channel 3120. When the weight 3126 is extracted from the body 3106,
the weight 3126 can slide relative to cover 3128 for removal and/or repositioning
on the cover 3128. As such, the position of the weight 3126 on the cover 3128 is adjustable
so that the weight assembly 3104 is used to adjust the GC and MOI of the club head
3100.
[0162] In this example, an inner surface of the cover 3128 includes at least one locating
lug 3136 spaced along the fastener axis. The weight 3126 includes one or more corresponding
hollows 3138 shaped and sized to receive at least a portion of the locating lug 3136.
Additionally, when the locating lug 3136 is engaged with the hollow 3138, the weight
3126 is retained more tightly by the cover 3128 to reduce or prevent rattling and
further movement of the weight 3126 in the locked configuration. In an aspect, the
cover 3128 can include a shelf 3140 that the weight 3126 is supported by. The shelf
3140 allows the weight 3126 to be extracted from within the channel 3120 when the
weight assembly 3104 is moved into the unlocked configuration.
[0163] In some examples, the first end 3132 of the cover 3128 may be engaged at least partially
with the channel 3120 so that the cover 3128 is coupled to the body 3106 of the club
head 3100 in the unlocked configuration. In other example, the cover 3128 can be completely
removable from the body 3106 of the club head 3100 as required or desired. By securing
the slidable weight 3126 within the body 3106 of the club head 3100 aerodynamic performance
of the outer surface 3116 of the club head 3100 can be increased.
[0164] FIG. 89 is a perspective view of a sole 3202 of another golf club head 3200 with
another weight assembly 3204 in a locked configuration. The golf club head 3200 includes
a body 3206, a striking face 3208, a lower edge 3210, an upper edge (not shown), a
toe (not shown), a heel 3212, a crown 3214, an outer surface 3216, an interior cavity
(not shown), and a hosel 3218, the functions of which are similar to the component
functions described above. The body 3206 may form any type club head as described
herein, such as, a metalwood-type club head, a fairway-metal type club head, an iron-type
club head, or a hybrid-type club head as required or desired. Furthermore, the features
of the weight assembly 3204 described below can additionally or alternatively be utilized
in any type club head described herein as required or desired.
[0165] In this example, a channel 3220 is defined by the body 3206 for supporting the weight
assembly 3204. The channel 3220 can include a first channel 3222 and a second channel
3224 that are in communication with one another. The first channel 3222 is defined
in the sole 3202 of the body 3206 and extends in a front-rear direction of the club
head 3200 with the striking face 3208 being the front of the club head 3200. The second
channel 3224 is defined in the sole 3202, and/or a transition area (e.g., skirt) where
the sole 3202 and the crown 3214 couple together. The second channel 3224 extends
in the toe-heel direction so that the CG and the MOI of the club head 3200 can be
adjusted for fade-draw bias. In an aspect, the second channel 3224 is disposed substantially
at a rear perimeter portion of the club head 3200 opposite the striking face 3208.
As such, the first channel 3222 and the second channel 3224 are oriented in substantially
orthogonal directions and on different planes of the club head 3200.
[0166] The weight assembly 3204 includes a slidable weight 3226 (shown in FIG. 91) slidably
engaged with a cover 3228 and a fastener 3230 configured to couple the cover 3228
to the body 3206. In this example, the cover 3228 includes a fastener tab 3232 and
a weight tray 3234. The fastener tab 3232 is sized and shaped to be received within
the first channel 3222 and the weight tray 3234 is sized and shaped to be received
within the second channel 3224. The fastener 3230 is coupled to the fastener tab 3232
(e.g., via a lock washer) and the weight tray 3234. The fastener 3230 is configured
to cooperate with both the fastener tab 3232 and the weight tray 3234 to retain and
secure the weight 3226 within the body 3206 of the club head 3200. Similar to the
examples described above, the weight assembly 3204 is configured to move between at
least a locked configuration, shown in FIG. 89, and an unlocked configuration, shown
in FIG. 90 and described further below. In the locked configuration, the cover 3228
is at least partially disposed within the recessed channel 3220, and the weight 3226
is secured within the body 3206 of the club head 3200 with its movement restricted.
In the unlocked configuration, the fastener 3230 releases the cover 3228 from the
body 3206 so that the weight assembly 3204 can move towards a weight adjustment configuration,
shown in FIG. 91 and described further below. In the weight adjustment configuration,
the position of the weight 3226 within the weight tray 3234 can be adjusted as required
or desired.
[0167] In the locked configuration, both the fastener tab 3232 and the weight tray 3234
are positioned within the body 3206 of the club head 3200 so that they are not protruding
and aligned with the outer surface 3216 of the club head 3200. Additionally, the weight
3226 is completely disposed within the body 3206 of the club head 3200, and secured
therein, in the locked configuration. The fastener 3230 retains the weight 3226 in
the recessed channel 3220 indirectly via the cover 3228 and so that the weight 3226
can be used to adjust the CG and the MOI of the club head 3200.
[0168] FIG. 90 is a perspective view of the weight assembly 3204 in an unlocked configuration.
In the unlocked configuration, the fastener 3230 is loosened such that it at least
partially raises out of the first channel 3222 along the fastener axis. Because the
fastener tab 3232 is coupled to the fastener 3230, the fastener tab 3232 also raises
at least partially out of the first channel 3222. In the example, the fastener 3230
is positioned towards a front section of the first channel 3222. This movement of
the fastener 3230 and the fastener tab 3232, however, does not correspond to the weight
tray 3234 moving within the second channel 3224. Rather, once the weight assembly
3204 is in the unlocked configuration, the user can utilize the fastener tab 3232
to pull the weight tray 3234 at least partially out of the second channel 3224 and
access the weight 3226 as illustrated in FIG. 91. In the unlocked configuration, the
weight 3226 may still be disposed completely within the body 3206 of the club head.
[0169] FIG. 91 is a perspective view of the weight assembly 3204 in a weight adjustment
configuration. FIG. 92 is a cross-sectional view of the weight assembly 3204 taken
along line 92-92 in FIG. 91. Referring concurrently to FIGS. 91 and 92, the weight
tray 3234 has a first end 3236 with a pool 3238 that is sized and shaped to receive
the weight 3226 and allow the weight to be selectively positionable (e.g., via sliding)
therein. A second end 3240 of the weight tray 3234 threadably engages with the fastener
3230 so that the fastener 3230 can rotate relative thereto. A slot 3242 is defined
between the first channel 3222 and the second channel 3224 so that the fastener 3230
can extend between the two and couple to both the fastener tab 3232 and the weight
tray 3234. The slot 3242 extends in a similar front-rear direction to the first channel
3222 so that the weight assembly 3204 can be linearly movable in a rearwards direction
towards the weight adjustment configuration when the weight assembly 3204 is unlocked
(e.g., disengage the fastener tab 3232 from the first channel 3222).
[0170] In operation, when the weight assembly 3204 is unlocked and then moved towards the
weight adjustment configuration, the first end 3236 of the weight tray 3234 projects
from the body 3206 so that the weight 3226 is accessible within the pool 3238 and
its position can be adjusted. In some examples, the weight 3226 can be completely
removable from the weight assembly 3204 as required or desired in the weight adjustment
configuration.
[0171] FIG. 93 is a perspective view of a sole 3302 of another golf club head 3300 with
another weight assembly 3304. FIG. 94 is a perspective view of the weight assembly
3304. Referring concurrently to FIGS. 93 and 94, the golf club head 3300 includes
a body 3306, a striking face 3308, a lower edge 3310, an upper edge (not shown), a
toe (not shown), a heel 3312, a crown 3314, an outer surface 3316, an interior cavity
(not shown), and a hosel 3318, the functions of which are similar to the component
functions described above. The body 3306 may form any type club head as described
herein, such as, a metalwood-type club head, a fairway-metal type club head, an iron-type
club head, or a hybrid-type club head as required or desired. Furthermore, the features
of the weight assembly 3304 described below can additionally or alternatively be utilized
in any type club head described herein as required or desired.
[0172] In this example, a recessed channel 3320 is defined within the sole 3302, and/or
a transition area (e.g., skirt) where the sole 3302 and the crown 3314 couple together.
The channel 3320 extends in the toe-heel direction so that the CG and the MOI of the
club head 3300 can be adjusted for fade-draw bias. In an aspect, the recessed channel
3320 and the weight assembly 3304 are disposed substantially at a rear perimeter portion
of the club head 3300 opposite the striking face 3308.
[0173] The weight assembly 3304 includes an insert 3322 that is configured to be inserted
into the recessed channel 3320 and coupled to the body 3306 of the club head 3300.
The insert 3322 has one or more weights coupled thereto. In this example, a first
weight 3324 and a second weight 3326 are coupled to the insert 3322. The first weight
3324 may be a different mass than the second weight 3326. An actuator 3328 is also
coupled to the insert 3322 and disposed between the weights 3324, 3326. In the example,
the actuator 3328 is rotatable relative to the insert 3322 with an enlarged head 3330
and a leadscrew 3332. The enlarged head 3330 is captured within the insert 3322 and
the leadscrew 3332 extends in a direction away from the insert 3322. The actuator
3328, however, is not used to couple the weight assembly 3304 to the body 3306 of
the club head 3300. Rather, the insert 3322 includes a locking member 3334 configured
to selectively engage with the body 3306 of the club head 3300 and secure the weight
assembly 3304 within the recessed channel 3320. The locking member 3334 is engaged
with the leadscrew 3332 and has a pair of opposing ends 3336 that project from the
insert 3322.
[0174] In operation, the weight assembly 3304 is configured to move between a locked configuration,
shown in FIG. 95 and described further below, and an unlocked configuration, shown
in FIG. 96 and described further below. In the locked configuration, the insert 3322
is secured within the recessed channel 3320 via the ends 3336 of the locking member
3334 so that the weights 3324, 3326 are coupled to the golf club head 3300. In the
unlocked configuration, the ends 3336 of the locking member 3334 disengage with the
body 3306 of the club head 3300 so that the insert 3322 can be removed from the recessed
channel 3320. Once the insert 3322 is removed, one or more of the weights 3324, 3326
can be changed out and replaced to adjust the weight in the weight assembly 3304.
In other examples, the insert 3322 can be flipped around and inserted back into the
recessed channel 3320 so as to adjust the position of the weights 3324, 3326 within
the golf club head 3300.
[0175] FIG. 95 is a cross-sectional view of the weight assembly 3304 taken along line 93-93
in FIG. 93 in a locked configuration. In the locked configuration, the actuator 3328
is rotated such that the locking member 3334 is positioned substantially orthogonal
to the rotation axis and in a linear orientation. This position of the locking member
3334 as illustrated in FIG. 95, results in the ends 3336 projecting from the insert
3322 and engaging with corresponding chambers 3338 defined in the body 3306 of the
club head and within the recessed channel 3320. The locking member 3334 engaging with
the body 3306 couples the weight assembly 3304 to the club head and secure the position
and orientation of the weights 3324, 3326. The actuator 3328 is rotatable so as to
move the locking member 3334 towards an unlocked configuration as described below
to enable the insert 3322 to be removed and decoupled from the body 3306 of the club
head.
[0176] FIG. 96 is a cross-sectional view of the weight assembly 3304 taken along line 93-93
in FIG. 93 in an unlocked configuration. The locking member 3334 is a flexible member
such that when the actuator 3328 is rotated, the rotational movement of the leadscrew
3332 induces corresponding linear movement on the center of the locking member 3334.
As such, the locking member 3334 can curve so as to retract the ends 3336 into the
insert 3322. This retraction of the ends 3336 of the locking member 3334 disengages
the ends 3336 from the chambers 3338 and allows the weight assembly 3304 to be removed
from the recessed channel 3320 and the body 3306 of the club head. In the example,
the ends 3336 of the locking member 3334 are stiffer relative to the middle section
so that the ends 3336 are able to engage and secure to the recessed channel 3320.
[0177] The unlocked configuration allows the weights 3324, 3326 to be replaced or for the
insert 3322 to be reinserted into the recessed channel 3320 in a flipped position
and adjust the GC and MOI of the club head. The insert 3322 can include a pair of
stops 3340 that engage with the ends 3336 of the locking member 3334 so as to help
impart the curve into the locking member 3334 in the unlocked configuration. In this
example, the weight assembly 3304 can be substantially systematical in both the toe-heel
direction and sole-crown direction so that the insert 3322 can be used to reposition
the weights 3324, 3326 within the body 3306. Additionally, the shape and size of the
recessed channel 3320 enables the locking member 3334 to move as described herein.
[0178] FIG. 97 is a bottom view of a sole 3402 of a golf club head 3400 with another weight
assembly 3404. FIG. 98 is a perspective cross-sectional view of the golf club head
3400 taken along line 97-97 in FIG. 97 and in an locked configuration. FIG. 99 is
another perspective cross-sectional view of the golf club head 3400 taken along line
97-97 in FIG. 97 and in an unlocked configuration. Referring concurrently to FIGS.
97-99, the golf club head 3400 is a fairway-metal type golf club head having a body
3406 that includes a striking face 3408 with a lower edge 3410 and an upper edge 3412
extending between a toe 3414 and a heel 3416. The sole 3402 extends from the lower
edge 3410 on the bottom side of the club head 3400 and a crown 3418 extends from the
upper edge 3412 on the top of the club head 3400. The sole 3402, the striking face
3408, and the crown 3418 are coupled together so as to define an outer surface 3420
of the body 3406 with an interior cavity 3422 formed within. A hosel 3424 is disposed
at the heel 3416 and is configured to couple to a shaft (not shown). The functions
of the components (e.g., sole, striking face, crown, hosel, etc.) of the fairway-metal
type golf club head 3400 are similar to the component functions described above. The
body 3406 may form any type club head, such as a metalwood-type club head, an iron-type
club head, or a hybrid-type club head as required or desired. Furthermore, the features
of the weight assembly 3404 described below can additionally or alternatively be utilized
in any type club head described herein as required or desired.
[0179] In this example, a recessed channel 3426 is defined within the sole 3402 of the body
3406 of the club head 3400. The channel 3426 extends in the toe 3414 - heel 3416 direction
so that that the CG and the MOI of the club head 3400 can be adjusted for fade-draw
bias. The weight assembly 3404 includes a slidable weight 3428 disposed at least partially
within the channel 3426 and configured to slide therein, a cover 3430 that extends
at least partially over the channel 3426 and adapted to releasably secure the weight
3428 within the channel 3426, and a fastener 3432 configured to couple the cover 3430
to the body 3406. The fastener 3432 retains the weight 3428 in the recessed channel
3426 indirectly via the cover 3430 so that the weight 3428 can be used to adjust the
CG and the MOI of the club head 3400. In this example, the weight assembly 3404 and
the recessed channel 3426 are located at a frontal section of the golf club head 3400.
[0180] Similar to the examples described above, the weight assembly 3404 is configured to
move between at least two positions via the fastener 3432, for example, a locked configuration,
shown in FIG. 98, and an unlocked configuration, shown in FIG. 99. In the locked configuration,
the cover 3430 is at least partially disposed within the recessed channel 3426 in
a secured position, and the weight 3428 is secured within the channel 3426 with its
movement restricted. When the weight assembly 3404 is in the locked configuration,
the weight 3428 is completely disposed within the channel 3426 and no portion of the
weight 3428 extends above the outer surface 3420 of the body 3406. Because the weight
3428 is completely disposed within the recessed channel 3426 and at least aligned
with, or below, the outer surface 3420 of the body 3406, the smoothness of the outer
surface 3420 of the club head 3400 is maintained so as to promote good ground interaction.
In the unlocked configuration, the fastener 3432 enables the cover 3430 to move along
the fastener axis towards a raised position so that the weight 3428 is released and
can slide relative to the cover 3430 and the body 3406. The fastener 3432 is coupled
to cover 3430 with a retaining clip 3433. The retaining clip 3433 is configured to
couple the fastener 3432 to the cover 3430 so that the fastener 3432 can rotate around
the fastener axis and relative to the cover 3430, however, the fastener 3432 and cover
3430 are coupled together for corresponding linear movement along the fastener axis.
In an aspect, the retaining clip 3433 includes a lock washer. In this example, the
cover 3430 includes a retention rib 3434 that is configured to slidably engage with
a slit 3435 defined in the weight 3428. The retention rib 3434 improves retention
of the weight 3428 with the cover 3430 and as the weight assembly 3404 moves between
configurations. The retention rib 3434 is described in further detail below.
[0181] FIG. 100 is another bottom view of the sole 3402 of the golf club head 3400. The
weight assembly 3404 (shown in FIGS. 97-99) is not shown for clarity. The recessed
channel 3426 is defined by a bottom track 3436 and two opposing sidewalls 3438, 3440.
A first sidewall 3438 is adjacent the striking face 3408 and a second sidewall 3440
is adjacent to the rear of the sole 3402. A nut 3442 is formed within the sole 3402
of the body 3406 proximate the second sidewall 3440. The nut 3442 is configured to
engage the fastener 3432 so that the cover 3430 (both shown in FIGS. 97-99) is directly
coupled to the body 3406. Additionally, the recessed channel 3426 is defined by two
opposing end walls 3444, 3446. A toe end wall 3444 is located on the toe side of the
club head 3400 and a heel end wall 3446 is located on the heel side of the club head
3400. In this example, no chambers or openings are defined at the ends of the recessed
channel 3426 and the cover 3430 does not have any corresponding projections. In an
aspect, the fastener 3432 is the only component of the weight assembly 3404 that extends
into the interior cavity of the body 3406, for example, via the nut 3442. This configuration
of the club head 3400 reduces dirt and debris from accumulating within the channel
3426 and within the body 3406.
[0182] The bottom track 3436 includes a plurality of bosses 3448 projecting into the channel
3426. In this example, there are five bosses 3448 equally spaced in the toe-heel direction.
The bosses 3448 are configured to selectively engage with the weight 3428 when in
the locked configuration (shown in FIG. 98) and so as to assist with positioning and
retaining the weight 3428 within the recessed channel 3426 as described herein. In
the example, the bosses 3448 can have a substantially frustoconical shape. Additionally,
the first sidewall 3438 includes a plurality of dimples 3450 that correspond to the
plurality of bosses 3448. The dimples 3450 are configured to selectively engage with
the weight 3428 when in the locked configuration and so as to assist with positioning
and retaining the weight 3428 within the recessed channel 3426 as described herein.
In the example, there are five bosses 3448 and five dimples 3450 so that the weight
3428 is selectively positionable at five predefined positions. It should be appreciated
that any other number of predefined positions, (e.g., three) can be utilized as required
or desired.
[0183] Between the first sidewall 3438 and the end walls 3444, 3446, the recessed channel
3426 is defined by an oblique wall 3452. The oblique walls 3452 are formed at the
terminal end of the channel 3426 in the toe-heel direction. Because the projections
and chambers have been eliminated from the weight assembly 3404 when compared to prior
examples, the oblique walls 3452 are configured to engage with the cover 3430 and
secure the ends of the cover 3430 when in the locked configuration.
[0184] FIG. 101 is an inside surface view of the cover 3430 and the weight 3428 of the weight
assembly 3404 (shown in FIGS. 97-99). FIG. 102 is a side view of the cover 3430 and
the weight 3428. Referring concurrently to FIGS. 101 and 102, the cover 3430 has a
first end 3454 and an opposite second end 3456. A rabbet 3458 is formed on one side
of the cover 3430 and extends at least partially between the first end 3454 and the
second end 3456. The rabbet 3458 is defined by at least an outer wall 3460 that forms
an exterior surface of the cover 3430 and a sidewall 3462 of the cover 3430. The rabbet
3458 is sized and shaped to at least partially receive the weight 3428 and allow the
weight 3428 to slide therein. An end wall 3464 is defined at both the first end 3454
and the second end 3456 and define a terminal end of the rabbet 3458. A fastener receiver
3466 is disposed opposite of the rabbet 3458 on the cover 3430 and is configured to
support the fastener 3432 (shown in FIGS. 97-99) at an aperture 3468. The fastener
3432 couples the cover 3430 to the body of the club head at the fastener receiver
3466.
[0185] The retention rib 3434 projects from the outer wall 3460 within the rabbet 3458 and
is elongated extended in a direction between the first end 3454 and the second end
3456 of the cover 3430. The retention rib 3434 is configured to engage the weight
3428 so as to improve the retention of the weight 3428 to the cover 3430. The retention
rib 3434 is shaped and sized to be at least partially received within the slit 3435
(shown in FIGS. 98-99) of the weight 3428. This engagement between the weight 3428
and the cover 3430 via the retention rib 3434 enables the weight 3428 to move with
the cover 3430 between the locked and unlocked configuration and so that the weight
3428 can be slidably repositioned when in the unlocked configuration. In this example,
the retention rib 3434 is discontinuous in the elongated direction so that the weight
3428 can be completely removed from the weight assembly as required or desired.
[0186] In the example, the retention rib 3434 can include two discrete sections, a first
rib 3470 and a second rib 3472 separated by a gap 3474 that is configured to allow
the weight 3428 to be at least partially removably received within the rabbet 3458.
As shown in FIG. 101, the retention rib 3434 is disposed proximate a distal end of
the outer wall 3460 and on the opposite side of the cover 3430 from the fastener receiver
3466. As such, the retention rib 3434 is spaced 3476 from the sidewall 3462 of the
cover 3430. The retention rib 3434 extends from each of the end walls 3464 and the
gap 3474 is disposed proximate the second end 3456 of the cover 3430. In another aspect,
the gap 3474 can be disposed proximate the first end 3454 of the cover 3430, or proximate
a midpoint of the cover 3430. In other aspects, the gap 3474 can be disposed at one
of the end walls 3464 such that the retention rib 3434 only extends from one end wall
3464, or more than one gap 3474 can be present within the retention rib 3434. In still
another example, two or more parallel retention ribs 3434 can be used as required
or desired.
[0187] The cover 3430 has an outside surface 3478 that is configured to align with the outer
surface of the club head when in the locked configuration, and an opposite inside
surface 3480 that faces the recessed channel 3426 (shown in FIG. 100) of the club
head. A thickness 3482 of the cover 3430 is defined between the outside surface 3478
and the inside surface 3480 in a direction that is substantially parallel to a fastener
axis of the fastener 3432 (shown in FIGS. 97-99). The thickness 3482 of the cover
3430 at the end walls 3464 is substantially equal to the thickness 3482 of the cover
3430 at a midpoint of the rabbet 3458 between the first end 3454 and the second end
3456. As such, the end walls 3464 of the cover 3430 are devoid of any projections
and engage directly with the recessed channel 3426 of the club head.
[0188] At least one hollow 3484 is defined in the weight 3428 and in a surface that is opposite
of the slit 3435 (shown in FIGS. 98-99). The hollow 3484 is sized and shaped to engage
with the boss 3448 disposed within the channel 3426 (both shown in FIG. 100). In the
example, the hollow 3484 includes a fully defined hollow 3484 and two partially defined
hollows 3484 that flank the fully defined hollow 3484. This configuration enables
for use of a more elongated weight 3428 while accommodating an increase in the amount
of weight positioning locations, e.g., five and as illustrated in the depicted example.
[0189] FIG. 103 is another inside surface view of the cover 3430. FIG. 104 is a cross-sectional
view of the cover 3430 taken along line 104-104 in FIG. 103. Referring concurrently
to FIGS. 103 and 104, certain components are described above, and thus, are not necessarily
described further. The rabbet 3458 is formed by the outer wall 3460 and the sidewall
3462. The retention rib 3434 is disposed proximate the distal end of the outer wall
3460. A shelf 3486 extends from the distal end of the sidewall 3462 and is configured
to at least partially support the weight 3428 (shown in FIGS. 101-102). The retention
rib 3434 and the shelf 3486 extend in substantially orthogonal directions. In the
example, the retention rib 3434 has a substantially square-shaped cross-section. It
should be appreciated that the retention rib 3434 can have any other cross-sectional
shape as required or desired.
[0190] In this example, the rabbet 3458 has a length 3488 that is defined between the end
walls 3464 at the first and second ends of the cover 3430. The gap 3474 of the retention
rib 3434 also has a length 3490 that is defined between the two sections of the rib.
In an example, the length 3488 of the rabbet 3458 is between about two to four times
the length 3490 of the gap 3474. In an aspect, the length 3488 of the rabbet 3458
is about three times the length 3490 of the gap 3474. As shown in FIG. 103, the retention
rib 3434 has an arcuate shape in plan view that corresponds to the elongated shape
of the rabbet 3458 defined within the cover 3430.
[0191] The end walls 3464 at each end of the cover 3430 have their inner surface aligned
with the inner surface of the sidewall 3462 such that the end walls 3464 directly
engage with the recessed channel 3426 (shown in FIG. 100) without the use of projections.
Each end of the cover 3430 also includes a chamfer 3492 that corresponds to the oblique
walls 3452 (shown in FIG. 100) of the channel 3426 which enables the ends of the cover
to securely engage with the club head in the locked configuration and reduce weight
rattling therein.
