Field of the Invention
[0001] The present invention relates to a hinge and, more particularly, to a hinge having
a damping device capable of different damping actions.
Background of the Invention
[0002] US Patent No. 8,561,262 B1 discloses a damping device for a hinge assembly. According to its specification,
the damping hinge assembly includes a housing (10), an arm (12), at least one spring
(14), a maintaining member (16), a damper (18), and an adjustment member (20). The
arm (12) is pivotally connected to the housing (10). The housing (10) includes a chamber
(36). The spring (14) is mounted in the chamber (36) of the housing (10) and serves
to provide a resilient closing force when the housing (10) is pivoted with respect
to the arm (12) and is thereby being closed with respect thereto.
[0003] The maintaining member (16) is fixedly mounted in the chamber (36) of the housing
(10) and has a path (72) for receiving the damper (18). The damper (18) is mounted
in the path (72) of the maintaining member (16) and corresponds to the arm (12). The
damper (18) has a piston rod (76). The adjustment member (20) is movably mounted to
the maintaining member (16) and has a protruded portion (92) to correspond to the
piston rod (76) of the damper (18). When the adjustment member (20) has been displaced
with respect to the maintaining member (16) to a first position, the protruded portion
(92) of the adjustment member (20) is aligned with the piston rod (76) of the damper
(18). Therefore, when the housing (10) is being closed with respect to the arm (12)
in this state, the damper (18) is pushed and displaced by the arm (12). As a result,
the piston rod (76) of the damper (18) is pressed against the protruded portion (92)
of the adjustment member (20) and is thereby retracted to produce a damping effect.
If the adjustment member (20) has been displaced with respect to the maintaining member
(16) to a second position instead, the protruded portion (92) of the adjustment member
(20) will not correspond in position to the piston rod (76) of the damper (18), and
if the housing (10) is subsequently closed with respect to the arm (12), the piston
rod (76) of the damper (18) will not be pressed against the protruded portion (92)
of the adjustment member (20) and hence will not produce any damping effect.
[0004] In short, the piston rod (76) of the damping device can produce a damping effect
when the adjustment member (20) has been displaced with respect to the maintaining
member (16) to the first position, but if the adjustment member (20) has been displaced
with respect to the maintaining member (16) to the second position, the piston rod
(76) of the damping device cannot be pressed against the protruded portion of the
adjustment member to produce the damping effect. In other words, the damping function
of the damping device only has an ON state and an OFF state. Lacking a damping function
adjusting mechanism, the damping device of the aforesaid US Patent still leaves room
for improvement.
Summary of the Invention
[0005] The present invention relates to a hinge which has a damping device capable of different
damping actions.
[0006] According to one aspect of the present invention, a hinge includes a hinge arm, a
hinge cup, at least one spring, a retainer, a damper, and an adjusting member. The
hinge cup is pivotally connected to the hinge arm and includes a room. The at least
one spring is mounted in the room of the hinge cup and serves to provide a resilient
closing force when the hinge cup is pivoted with respect to the hinge arm and is thereby
being closed with respect thereto. The retainer is mounted in the room of the hinge
cup and has a channel. The damper is mounted in the channel of the retainer, corresponds
to the hinge arm, and has a piston rod. The adjusting member is movably mounted to
the retainer and includes a surface, a first contact portion, and a second contact
portion. The first contact portion and the surface define a first distance therebetween
while the second contact portion and the surface define a second distance therebetween.
The first distance is greater than the second distance. When the adjusting member
has been displaced with respect to the retainer to a first position, the first contact
portion of the adjusting member corresponds to the piston rod of the damper, and when
the hinge cup is subsequently closed with respect to the hinge arm, the damper is
pushed and displaced by the hinge arm such that the piston rod of the damper is pressed
against the first contact portion of the adjusting member and produces a damping effect.
When the adjusting member has been displaced with respect to the retainer to a second
position, the second contact portion of the adjusting member corresponds to the piston
rod of the damper, and when the hinge cup is subsequently closed with respect to the
hinge arm, the damper is pushed and displaced by the hinge arm such that the piston
rod of the damper is pressed against the second contact portion of the adjusting member
and produces a damping effect.
[0007] Preferably, the adjusting member has an engaging portion, the retainer has an upper
portion, and the upper portion has a peripheral portion provided with a first engaging

the second engaging part of the retainer.
[0008] Preferably, the adjusting member further includes a third contact portion, the third
contact portion and the surface define a third distance therebetween, and the second
distance defined between the second contact portion and the surface is greater than
the third distance. When the adjusting member has been displaced with respect to the
retainer to a third position, the third contact portion of the adjusting member corresponds
to the piston rod of the damper, and when the hinge cup is subsequently closed with
respect to the hinge arm, the damper is pushed and displaced by the hinge arm such
that the piston rod of the damper is pressed against the third contact portion of
the adjusting member and produces a damping effect. In addition, the adjusting member
preferably has an engaging portion, the retainer preferably has an upper portion,
and the upper portion preferably has a peripheral portion provided with a first engaging
part, a second engaging part, and a third engaging part. When the adjusting member
has been operated and thereby displaced with respect to the retainer to the first
position, the engaging portion of the adjusting member is engaged with the first engaging
part of the retainer. When the adjusting member has been operated and thereby displaced
with respect to the retainer to the second position, the engaging portion of the adjusting
member is engaged with the second engaging part of the retainer. When the adjusting
member has been operated and thereby displaced with respect to the retainer to the
third position, the engaging portion of the adjusting member is engaged with the third
engaging part of the retainer. Preferably, the retainer further has a lower portion
opposite the upper portion and has a main body connected between the upper portion
and the lower portion of the retainer, the lower portion has a peripheral portion
provided with a lip, and the adjusting member is movably mounted between the upper
portion and the lip of the lower portion of the retainer. Preferably, the adjusting
member further includes an operating portion. It is also preferable that the upper
portion of the retainer has a first mark, a second mark, and a third mark, and that
the adjusting member further includes a pointed portion which corresponds to the first
mark when the adjusting member has been displaced with respect to the retainer to
the first position, the second mark when the adjusting member has been displaced with
respect to the retainer to the second position, and the third mark when the adjusting
member has been displaced with respect to the retainer to the third position.
[0009] Preferably, the hinge cup further includes a pair of sidewalls, a bottom wall connected
between the pair of sidewalls, a front end wall connected between the front ends of
the pair of sidewalls, and a rear end wall connected between the rear ends of the
pair of sidewalls, wherein the pair of sidewalls, the bottom wall, the front end wall,
and the rear end wall jointly define the room.
[0010] Alternatively, it is preferable that the hinge cup further includes a pair of sidewalls
and a front end wall connected between the front ends of the pair of sidewalls, that
each of the sidewalls has a shaft hole adjacent to the front end wall so that the
shaft holes correspond to each other, that the hinge arm includes a pair of cam portions
and a bushing connected between the pair of cam portions, and that the hinge arm is
pivotally connected to the hinge cup by a shaft passing through the shaft hole of
each of the sidewalls and the bushing of the hinge arm.
[0011] Preferably, the at least one spring includes a pair of springs which are in the form
of torsion springs and each of which includes a winding portion. Preferably, the hinge
cup further includes a pair of sidewalls and a bottom wall connected between the pair
of sidewalls, each of the sidewalls has a pin hole so that the pin holes correspond
to each other, the bottom wall includes a pair of lugs each having a through hole
corresponding to the pin holes of the pair of sidewalls, each respective springs is
mounted between a corresponding one of the pair of sidewalls and a corresponding one
of the pair of lugs and is connected to the hinge cup by a respective pin which passes
through the pin hole of the corresponding one of the pair of sidewalls, the winding
portion of the each respective spring, and the through hole of the corresponding one
of the pair of lugs.
[0012] Preferably, the hinge cup includes a pair of sidewalls, each of the sidewalls has
a positioning hole so that the positioning holes correspond to each other, the retainer
has two lateral sides each provided with an engaging element, and each of the engaging
elements corresponds to and is engaged in a corresponding one of the positioning holes
such that the retainer is fixed in the room of the hinge cup.
[0013] One of the features of the embodiments of the present invention is that the adjusting
member has at least two contact portions which enable the piston rod of the damper
to provide different damping actions. A user can choose the desired damping action
to satisfy the operational needs in closing a door of a piece of furniture (or the
like).

Detailed Description of the Invention
[0015] FIG. 1 shows how a hinge 10 and a damping device 12 in an embodiment of the present
invention are applied to a cabinet 14 (e.g., a cupboard or a similar piece of furniture).
The cabinet 14 has a fixed portion 16 and a door 18. The door 18 can be opened and
closed with respect to the fixed portion 16.
[0016] The hinge 10 includes a hinge cup 20, a hinge arm 22, and at least one spring 24.
The hinge cup 20 is pivotally connected to the hinge arm 22 and is mounted to the
door 18 of the cabinet 14. The hinge arm 22, on the other hand, is mounted to the
fixed portion 16 of the cabinet 14. When the door 18 of the cabinet 14 is closed (or
opened) with respect to the fixed portion 16, the hinge cup 20 is closed (or opened)
with respect to the hinge arm 22. The at least one spring 24 and the damping device
12 are mounted in the hinge cup 20. In the course in which the hinge cup 20 is opened
with respect to the hinge arm 22, the hinge cup 20 responds to the force generated
by the at least one spring 24 and is subjected to an opening force, and in the course
in which the hinge cup 20 is closed with respect to the hinge arm 22, the hinge cup
20 responds to the force generated by the damping device 12 and is subjected to a
dampened closing force.
[0017] As shown in FIG. 1 and FIG. 2, the hinge cup 20 includes a pair of sidewalls 26,
a bottom wall 28, a front end wall 30, and a rear end wall 32. The pair of sidewalls
26 have a pair of corresponding shaft holes 34 adjacent to the front end wall 30,
a pair of corresponding pin holes 36, and a pair of corresponding positioning holes
38 (only one of the positioning holes 38 is shown in FIG. 2 due to limitation of the
viewing angle). The bottom wall 28 extends and is connected between the bottoms of
the pair of sidewalls 26. The front end wall 30 extends and is connected between the
front ends of the pair of sidewalls 26. The rear end wall 32 extends and is connected
between the rear ends of the pair of sidewalls 26. The pair of sidewalls 26, the bottom
wall 28, the front end wall 30, and the rear end wall 32 jointly define a room 40.
The bottom wall 28 includes a pair of lugs 42 within the room 40, each lug 42 having
a through hole 44 corresponding to the pin holes 36 of the sidewalls 26.
[0018] The hinge arm 22 includes a pair of cam portions 46 (only one of the cam portions
46 is shown in FIG. 2 due to limitation of the viewing angle) and a bushing 48. The
bushing 48 is connected between the cam portions 46. A shaft 50 passes through the
shaft holes 34 of the hinge cup 20 and the bushing 48 of the hinge arm 22 such that
the hinge arm 22 is pivotally connected to the hinge cup 20.
[0019] The at least one spring 24 is mounted at a proper position in the room 40 of the
hinge cup 20. When the hinge cup 20 is pivoted with respect to the hinge arm 22 in
order to be closed with respect thereto, the at least one spring 24 provides a resilient
closing force in the last part of the closing movement. In one preferred embodiment,
the at least one spring 24 is implemented by a pair of springs 24, but the number
of the at least one spring 24 is not limited to two. The pair of springs 24 are in
the form of torsion springs, each including a first rod 52a, a second rod 52b, and
a winding portion 54 connected between the first rod 52a and the second rod 52b. Each
respective spring 24 is mounted between a corresponding sidewall 26 and a corresponding
lug 42 and is connected to the hinge cup 20 and secured in the room 40 by a respective
pin 56 passing sequentially through the pin hole 36 of the corresponding sidewall
26, the winding portion 54 of the each respective spring 24, and the through hole
44 of the corresponding lug 42. In addition, the first rod 52a of each spring 24 presses
against a corresponding cam portion 46 of the hinge arm 22.
[0020] Preferably, the first rod 52a of each spring 24 is mounted with a protective cover
60, and each protective cover 60 is made of plastic, for example, and has a columnar
curved surface 62. Thus, thanks to the protective covers 60, the first rods 52a of
the springs 24 will press against the respective cam portions 46 of the hinge arm
22 in an indirect manner to prevent product reliability issues which may otherwise
occur if the cam portions 46 of the hinge arm 22 are in direct contact with and therefore
subject to wear by the first rods 52a of the springs 24. Moreover, after the hinge
10 is used for a while, the columnar curved surface 62 of each protective cover 60
typically has an increased area of contact, and hence of friction, between itself
and the corresponding cam portion 46, thereby stepping up the product's reliability
in use.
[0021] As shown in FIG. 2 and FIG. 3, the damping device 12 includes a retainer 64, a damper
66, and an adjusting member 68.
[0022] The retainer 64 is mounted in the room 40 of the hinge cup 20. The retainer 64 includes
an upper portion 70, a lower portion 72 opposite the upper portion 70, and a main
body 74 connected between the upper portion 70 and the lower portion 72.
[0023] As shown in FIG. 2, the upper portion 70 has a surface provided with a first mark
76a, a second mark 76b, and a third mark 76c. In addition, as shown in FIG. 3, the
upper portion 70 has a peripheral portion facing the rear end wall 32 of the hinge
cup 20 and provided with a first engaging part 78a, a second engaging part 78b, and
a third engaging part 78c. Preferably, the first mark 76a, the second mark 76b, and
the third mark 76c are words, numbers, or graphic marks through which an operator
can know and identify each damping action the damping device 12 is capable of.
[0024] The lower portion 72 has a peripheral portion provided with a lip 80 and has two
lateral sides each provided with an engaging element 82. Each engaging element 82
is engaged with a corresponding positioning hole 38 of the hinge cup 20 such that
the retainer 64 is mounted and fixed in the room 40 of the hinge cup 20. The main
body 74 has a channel 84.
[0025] The damper 66 corresponds to and is movably mounted in the channel 84 of the retainer
64. When the hinge cup 20 is being closed with respect to the hinge arm 22, the damper
66 mounted in the channel 84 of the retainer 64 corresponds to and can be pressed
and displaced by the hinge arm 22.
[0026] Preferably, the damper 66 has a piston rod 86 which corresponds to and can be pressed
against the adjusting member 68. When the piston rod 86 is in a normal state, in which
it is not pushed by an external force, a damping medium (not shown) in the damper
66 keeps the piston rod 86 jutting out of the damper 66 so that the piston rod 86,
once pushed by an external force, can provide a damping action against the external
force. As the principle of the damping action of the damper 66 is readily understandable
by a person skilled in the art, further description is omitted herein for the sake
of simplicity.
[0027] Referring to FIG. 2∼FIG. 4, the adjusting member 68 is movably mounted to the retainer
64 and is located between the upper portion 70 and the lower portion 72 (the lip 80)
of the retainer 64. The adjusting member 68 includes an upper frame 88, a lower frame
90 opposite the upper frame 88, and a lateral plate 92 connected between the upper
frame 88 and the lower frame 90 and having a surface 94. The adjusting member 68 is
movably engaged with the retainer 64 via one of the upper frame 88 and the lower frame
90.
[0028] In addition, the upper frame 88 of the adjusting member 68 has a pointed portion
96, an operating portion 98, and an engaging portion 100. When the adjusting member
68 is adjusted by being displaced with respect to the retainer 64, the engaging portion
100 can be selectively disposed in the first engaging part 78a, the second engaging
part 78b, or the third engaging part 78c of the retainer 64 so as to engage loosely
with and be positioned in that engaging part. In the meantime, the pointed portion
96 is moved to point to a corresponding one of the first mark 76a, the second mark
76b, and the third mark 76c of the retainer 64 in order for the operator to know the
position to which the adjusting member 68 has been adjusted. The operating portion
98 makes it easy for the operator to turn the adjusting member 68, i.e., to displace
the adjusting member 68 with respect to the retainer 64.
[0029] Referring to FIG. 4 and FIG. 5, the lateral plate 92 of the adjusting member 68 has
a first contact portion 102, a second contact portion 104, and a third contact portion
106. The distance between the surface 94 of the lateral plate 92 and the first contact
portion 102 is defined as the first distance D1. The distance between the surface
94 of the lateral plate 92 and the second contact portion 104 is defined as the second
distance D2. The distance between the surface 94 of the lateral plate 92 and the third
contact portion 106 is defined as the third distance D3. The first distance D1 is
greater than the second distance D2, and the second distance D2 is greater than the
third distance D3.
[0030] Referring to FIG. 6 in conjunction with FIG. 3, when the adjusting member 68 is operated
via the operating portion 98 and displaced with respect to the retainer 64 to a first
position, the engaging portion 100 becomes engaged with the first engaging part 78a
(see FIG. 4). Consequently, the pointed portion 96 of the adjusting member 68 points
to the first mark 76a, and the piston rod 86 of the damper 66 corresponds to the first
contact portion 102 (see FIG. 6). In this state, a first space S1 is formed between
the damper 66 and the hinge arm 22.
[0031] Referring to FIG. 7 in conjunction with FIG. 3, when the adjusting member 68 is operated
via the operating portion 98 and displaced with respect to the retainer 64 to a second
position, the engaging portion 100 becomes engaged with the second engaging part 78b.
Consequently, the pointed portion 96 of the adjusting member 68 points to the second
mark 76b, and the piston rod 86 of the damper 66 corresponds to the second contact
portion 104. In this state, a second space S2 is formed between the damper 66 and
the hinge arm 22.
[0032] Referring to FIG. 8 in conjunction with FIG. 3, when the adjusting member 68 is operated
via the operating portion 98 and displaced with respect to the retainer 64 to a third
position, the engaging portion 100 becomes engaged with the third engaging part 78c.
Consequently, the pointed portion 96 of the adjusting member 68 points to the third
mark 76c, and the piston rod 86 of the damper 66 corresponds to the third contact
portion 106. In this state, a third space S3 is formed between the damper 66 and the
hinge arm 22.
[0033] FIG. 9A∼FIG 9C illustrate how the hinge 10 and damping device 12 in an embodiment
of the present invention work after the adjusting member 68 has been adjusted to the
first position.
[0034] When the adjusting member 68 has been adjusted to the first position and the hinge
cup 20 is in an open state with respect to the hinge arm 22 (i.e., the state shown
in FIG. 9A), the hinge cup 20 can be pivoted with respect to the hinge arm 22 from
the open state to a closed state due to the fact that the hinge arm 22 is pivotally
connected to the hinge cup 20 via the shaft 50. During the closing process, the first
rods 52a of the springs 24 press against the cam portions 46 of the hinge arm 22 via
the protective covers 60 respectively, wherein the protective covers 60 serve to protect
either the first rods 52a of the springs 24 or the cam portions 46 of the hinge arm
22. Moreover, the springs 24 provide a resilient closing force in the last part of
the closing movement.
[0035] When the hinge cup 20 being closed with respect to the hinge arm 22 goes through
the last part of the closing movement (i.e., the state shown in FIG. 9B), the hinge
arm 22 pushes the damper 66 in a manner corresponding to the first space S1 such that
the piston rod 86 is pressed against the first contact portion 102 of the adjusting
member 68. More specifically, only when the hinge cup 20 has been closed with respect
to the hinge arm 22 to a first predetermined angle θ1 will the hinge arm 22 be able
to push the damper 66 and thereby displace the damper 66 in the channel 84 of the
retainer 64. By virtue of the damping medium 108 in the damper 66, the piston rod
86 produces a damping effect until the hinge cup 20 enters a closed state with respect
to the hinge arm 22 (i.e., the state shown in FIG. 9C). The damping medium 108 may
include a piston 110 and an elastic element 112. Preferably, the damping medium 108
further includes a damping medium fluid. In practice, the damping medium in the damper
66 is not limited to the above and can be designed as needed.
[0036] FIG. 10 illustrates how the hinge 10 and damping device 12 in an embodiment of the
present invention work after the adjusting member 68 has been adjusted to the second
position.
[0037] As in the case with the first position, when the adjusting member 68 has been adjusted
to the second position and the hinge cup 20 is being closed with respect to the hinge
arm 22 and goes through the last part of the closing movement, the hinge arm 22 pushes
the damper 66 in a manner corresponding to the second space S2 such that the piston
rod 86 is pressed against the second contact portion 104 of the adjusting member 68.
More specifically, only when the hinge cup 20 has been closed with respect to the
hinge arm 22 to a second predetermined angle θ2 will the hinge arm 22 be able to push
the damper 66, causing the damper 66 to displace in the channel 84 of the retainer
64. As a result, the piston rod 86 produces a damping effect until the hinge cup 20
enters a closed state with respect to the hinge arm 22.
[0038] FIG. 11 illustrates how the hinge 10 and damping device 12 in an embodiment of the
present invention work after the adjusting member 68 has been adjusted to the third
position.
[0039] As in the case with the first or the second position, when the adjusting member 68
has been adjusted to the third position and the hinge cup 20 is being closed with
respect to the hinge arm 22 and goes through the last part of the closing movement,
the hinge arm 22 pushes the damper 66 in a manner corresponding to the third space
S3 such that the piston rod 86 is pressed against the third contact portion 106 of
the adjusting member 68. More specifically, only when the hinge cup 20 has been closed
with respect to the hinge arm 22 to a third predetermined angle θ3 will the hinge
arm 22 be able to push the damper 66, causing the damper 66 to displace in the channel
84 of the retainer 64. As a result, the piston rod 86 produces a damping effect until
the hinge cup 20 enters a closed state with respect to the hinge arm 22.
[0040] According to the above, the adjusting member 68 can be adjusted in position with
respect to the retainer 64 so that, when the hinge cup 20 is being closed with respect
to the hinge arm 22 and goes through the last part of the closing movement, the hinge
arm 22 can push the damper 66 in a way corresponding to the adjustment, allowing the
damper 66 to produce the desired damping effect, e.g., the damping effect needed when
a door of a cabinet is being closed, with a view to protecting the door (or the cabinet)
and eliminating noise which may otherwise be generated when the door is being closed
with respect to the fixed portion of the cabinet.
[0041] It should be pointed out that the damping device 12 has at least two contact portions
102, 104, 106 which are differently spaced from the surface 94 of the adjusting member
68 and which therefore enable selective adjustment of the damping action of the damping
device 12 to satisfy different damping needs. While the present invention has been
disclosed by way of the foregoing preferred embodiments, those embodiments are not
intended to be restrictive of the present invention. The scope of patent protection
sought for the invention is defined by the appended claims.
