DETAILED DESCRIPTION
[0009] Referring generally to the Figures, an apparatus for cutting a circular pattern in
a sheet material and components thereof are shown according to an exemplary embodiment.
[0010] Referring to FIG. 1, a cutting apparatus 10 is shown according to an exemplary embodiment.
The apparatus 10 shown in FIG. 1 is configured to facilitate making circular cuts
in a sheet of material (e.g., a sheet of fabric). However, in other embodiments the
apparatus 10 may be configured to cut another desired (i.e., non-circular) shape in
a sheet of material, including other symmetrical shapes such as an oval, hexagon,
rectangle, triangle, and the like. The apparatus 10 includes a cutting device 12 (e.g.,
carriage, cutting tool, etc.) and a cutting template 14 (e.g., board). The cutting
template 14 includes a flat top surface 16, a raised outer edge 18 bordering rear
and side portions of the top surface 16, and a plurality of channels 20 (e.g., grooves,
guides, etc.) formed in the top surface 16 and through the template 14. Each of the
channels 20 is configured to receive the cutting device 12. The channels 20 are configured
to guide the cutting device 12 around the circumference of the channel's 20 predetermined
radius to make a circular cut. For instance, a material to be cut may be folded in
half and placed underneath the template 14. The cutting device 12 may then be placed
into one of the channels 20. The selected channel 20 is configured to guide the movement
of the cutting device 12 from one end of the channel 20 to the other. The movement
of the cutting device 12 causes a semi-circular cut through both halves of the sheet
material when a blade 34 (shown in FIG. 3) of the device 12 is extended, causing a
wholly circular pattern to be cut within the material. In other embodiments in which
the apparatus 10 is configured to cut a non-circular shape in the sheet of material,
the channels 20 may be configured (e.g., shaped) accordingly.
[0011] Referring to FIGS. 2-7, the cutting device 12 of the apparatus 10 is shown according
to an exemplary embodiment. The cutting device 12 is configured to move between a
first position (i.e., a retracted position) in which the blade 34 (e.g., rotary blade)
is retracted within the device 12 (shown in FIGS. 2-4), and a second position (i.e.,
a cutting, extended, or exposed position) in which the blade 34 is projected from
the device 12 to make a cut (shown in FIGS. 5-7). The cutting device 12 includes a
base 22, a handle 24 rotatably coupled to the base 22, and a blade cartridge 36 housing
the blade 34. The handle 24 is configured to be manipulated (e.g., held, received,
operated, moved, etc.) by an operator of the apparatus 10, including to move the device
12 within the channel 20 when the cutting device 12 is in the second position. The
handle 24 is freely rotatable relative to the base 22 and about a vertical axis provided
by the base 22, including as a cut is being performed within one of the channels 20.
The rotatable handle 24 allows a user of the apparatus 10 to maintain a comfortable
hand position and/or grip on the handle 24 as the user tracks the device 12 within
the channels 20 in the template 14.
[0012] Referring still generally to FIGS. 2-7, the handle 24 includes a body 70 having a
skirt 76 and a flange 72. The body 70, including the skirt 76 and the flange 72, may
be a single piece. The body 70 has an annular shape, having an opening formed therethrough
that is configured to receive at least a portion of the base 22 (see FIG. 8). The
handle 24 also includes a cap 26 removably coupled to and covering an open top end
of the body 70. For instance, the cap 26 and a portion of the body 70 may each include
corresponding threads configured to mate the cap 26 with the body 70. The handle 24
is sized and shaped to enable a user of the apparatus 10 to grip the handle 24 while
tracking the device 12 within the channels 20 of the template 14 when the device 12
is in the second position. The skirt 76, for instance, has a smaller maximum diameter
than the cap 26 or the flange 72, enabling a user to grip the handle 24 more easily
at the skirt 76. The skirt 76 is V-shaped, decreasing in diameter from a top end of
the skirt 76 (i.e., at or near the cap 26) to the lower end of the skirt 76 (i.e.,
at the flange 72).
[0013] In addition to being rotatable, the handle 24 is configured to move axially relative
to the base 22, along the vertical axis provided by the base 22. When a downward (e.g.,
compressive) force is applied to the handle 24 while the device 12 is in the first
position (shown in FIG. 4), the blade 34 of the cutting device 12 is moved from the
retracted position to the cutting position (as shown in FIG. 5). For instance, a manual
force may be applied by the user at the cap 26. Downward movement of the handle 24
forces the blade cartridge 36 downward in the same direction as the handle 24, causing
the blade 34 of the blade cartridge 36 to extend to the cutting position (as shown
in FIGS. 5 and 7). When the blade 34 is extended, the cutting device 12 may be used
to cut a desired pattern within a sheet of material. The handle 24 is spring-loaded
to return the device 12 (e.g., the blade 34) to the first position when the force
is removed.
[0014] Still referring generally to FIGS. 2-7, the base 22 has an annular disc shape, having
an opening 32 formed through the center of the base 22 to allow the blade 34 to extend
out from the base 22 to make a cut. The base 22 includes projections 30 (e.g., guides)
configured to interface with the channels 20 of the template 14, guiding movement
of the cutting device 12 within the channels 20 when the cutting device 12 is in the
cutting position. The projections 30 are intended to guide the blade 34 within the
channels 20, being positioned in line with the cutting path of the rotary blade 34.
The projections 30 may have a width approximately equal to the width of the channels
20 to prevent the blade 34 from wandering into the sides of the channels 20. By aligning
(e.g., centering) the blade 34 within the channels 20, the projections 30 may prevent
damage to the template 14 and/or the blade 34. The projections 30 include chamfers
60 in the illustrated embodiment. The chamfers 60 are intended to interface with complementary
features of the channels 20 to align the projections 30 (i.e., the cutting device
12) within the channels 20. The chamfers 60 may aid in aligning (e.g., centering)
the blade 34 within the corresponding channel 20 when the blade 34 is in the extended
position within the channel 20. In other embodiments, the projections 30 and the channels
20 may have other complementary shapes configured to align the projections 30 (and
the blade 34) within the channels 20. The base 22 also includes a flat bottom surface
74 configured to interface with the top surface 16 of the template 14 when the projections
30 are positioned within one of the channels 20. Tabs 28 are positioned opposite each
other on a top side of the base 22. The tabs 28 are intended to assist the user in
moving the cutting device 12 within the channels 20 by providing an indication of
the direction of the blade 34 when the blade 34 is not visible (e.g., is positioned
within one of the channels 20).
[0015] Referring now to FIGS. 8 and 9, the cutting device 12 is shown in further detail
and according to an exemplary embodiment. FIG. 8 shows a cross-sectional view of the
cutting device 12 when the cutting device 12 is between the first and second positions
(i.e., with the blade 34 partially extended). FIG. 9 shows a cross-sectional view
of the cutting device in the first position, but with the cap 26 removed. The blade
cartridge 36 is positioned within the cutting device 12. In an exemplary embodiment,
the blade cartridge 36 is a single unit configured to be removed and replaced when
the blade 34 requires replacement. The blade cartridge 36 provides a case for the
blade 34 so that a user of the cutting device 12 may remove the blade 34 without touching
the blade 34. The blade cartridge 36 includes a tab 38 having an annular flange 40,
as well as a housing 42 configured to store the blade 34. When the cutting device
12 is in the first (i.e., resting) position (as shown in FIG. 9), the tab 38 extends
vertically above the body 70 into an area that is typically covered by the cap 26.
The cap 26 includes a pocket 80 that is sized and shaped to accommodate the tab 38
when the cap 26 is coupled to the body 70 (as shown in FIG. 8). The tab 38 is configured
to be grasped by a user of the cutting device 12 to remove and replace the blade cartridge
36, and thus the blade 34. For instance, the cap 26 may be removed (as shown in FIG.
9) to reveal the tab 38. In an exemplary embodiment, the tab 38 is positioned parallel
to and on the same two-dimensional plane as the rotary blade 34.
[0016] Still referring to FIGS. 8 and 9, the base 22 includes a skirt 46 configured to receive
the blade cartridge 36. The cutting device 12 includes a spring 44 or other form of
biasing member positioned between the flange 40 of the blade cartridge 36 and the
skirt 46. The spring 44 is configured to push against both the flange 40 and the skirt
46, driving apart the blade cartridge 36 and the base 22 (i.e., the skirt 46) in absence
of an oppositional force (i.e., a force applied by a user of the device 12 to cut).
The spring 44 is configured to return the device 12 to the first (i.e., retracted)
position after the cut has been made. The flange 40 is captured within a pocket 78
formed by the body 70 and the cap 26, such that the body 70 and the cap 26 (i.e.,
the handle 24) are also driven upward by the force of the spring 44. The skirt 46
forms an annular outer rib 48 positioned at or near a top end of the skirt 46. An
inner surface of the handle 24 includes a shelf 58. The rib 48 is configured to provide
a stop for the shelf 58 (i.e., for the handle 24) against the force of the spring
44, preventing the handle 24 and/or the blade cartridge 36 from being de-coupled from
the base 22 by the force of the spring 44 by interfacing with the shelf 58 (as shown
in FIG. 9).
[0017] When a downward force is applied to the handle 24, the blade cartridge 36, and thus
the blade 34, are shifted similarly to expose the blade 34. The cap 26 includes a
projection 50 configured to engage the tab 38 of the blade cartridge 36 when the handle
24 is depressed. The cap 26 also includes interfaces 82 configured to engage the flange
40, and interfaces 84 configured to engage the body 70, moving the cartridge 36 and
the body 70 along with the cap 26. The cap 26 is configured to mate with a lip 52
formed by the body 70.
[0018] Referring to FIG. 10, the blade cartridge 36 is shown according to an exemplary embodiment.
As described previously, the cartridge 36 includes the cylindrical (e.g., annular)
housing 42 configured to house the blade 34. The housing 42 includes a track 54 configured
to provide a guide for the blade 34, preventing the blade 34 from twisting or moving
from side to side. The track 54 may also match with corresponding components of the
base 22 to align the blade cartridge 36 relative to the base 22. Similarly, the blade
cartridge 36 includes a guide 56 configured to match with a corresponding feature
of the base 22 to align the blade cartridge 36 relative to the base 22. In an exemplary
embodiment, the blade cartridge 36 is "keyed" (e.g., interlocked, mated, etc.) to
the base 22 such that the blade 34 cuts tangent to the circular pattern.
[0019] Referring to FIGS. 11-14, the template 14 of the cutting apparatus 10 is shown according
to an exemplary embodiment. As shown in FIGS. 11 and 12, the plurality of channels
20 are semi-circular in shape, with each of the plurality of channels 20 providing
a different predetermined circular cutting radius. The predetermined cutting radii
associated with each of the channels 20 corresponds to the radius of the circular
material pattern that will be produced using a selected channel 20. The channels 20
are arranged on the template 14 according to their cutting radius, in ascending order
from a front portion of the template 14 to a rear portion of the template 14 (i.e.,
at or near the rear raised edge 18). In an exemplary embodiment, the cutting radii
range from a minimum radius of approximately 5.08 centimeters (2 inches) to a maximum
diameter of approximately 15.24 centimeters (6 inches). In other embodiments, the
radii of the channels 20 may be larger or smaller, depending on the particular application.
In some embodiments, for instance, the template 14 may be manipulatable by an operator
of the apparatus 10 to create a custom channel having an operator-determined cutting
radius. As noted previously, in other embodiments the apparatus 10 may be configured
to cut another desired (i.e., non-circular) shape in a sheet of material. In such
embodiments, the channels 20 may be configured according to the desired shape. For
instance, in embodiments in which the desired cutting shape is an oval, the channels
20 may each be semi-ovular in shape.
[0020] Referring particularly to FIGS. 12-14, the template 14 includes a stop 64 formed
on a bottom surface 62 of the template 14. The stop 64 is formed across a length of
the bottom surface 62. The stop 64 is raised relative to the bottom surface 62 in
order to provide alignment for a sheet of fabric to be cut by the cutting device 12.
The stop 64 extends across the length of the template 14 and across each of the channels
20. However, the channels 20 are continuous and formed entirely through the template
14. Thus, as shown in FIG. 13, the stop 64 may be formed from a plurality of stop
strips positioned between each of the channels 20. In an exemplary embodiment, the
stop 64 is positioned across the diameter of each of the plurality of channels 20,
such that the portion of each of the channels 20 that is positioned above the stop
64 (according to the orientation of FIG. 12) has a semi-circular shape. Thus, if a
sheet of material is folded in half and the material's fold line is aligned with the
stop 64, the cutting device 12 is configured to make a circular shape within the material
through any of the channels 20.
[0021] Referring to FIGS. 13 and 14, the raised edge 18 is formed around a rear end and
the sides of the template 14. The raised edge 18 is configured to provide a handle
for an operator to manipulate the template 14. For instance, the raised edge 18 includes
ledges 66 (shown in FIG. 13) at each side of the template 14 for lifting the template
14. The raised edge 18 also includes a ledge 68 at a rear edge of the template 14.
The ledges 66 and 68 may be one continuous ledge formed at the top of the raised edge
18.
