I. FIELD OF THE INVENTION
Generally, a cutting guide having a seam allowance recess which can be used with a cutting tool to cut a piece of material.
II. BACKGROUND OF THE INVENTION
Conventional cutting guides used measure and cut material typically have a square or rectangular shape with a thickness sufficient to guide a cutting tool along one side to cut material extending beyond the periphery of the cutting guide. The cutting guide may also provide on one or both surfaces a set of visible marks spaced at intervals useful for measurement or placement of the cutting guide on the piece of material to be cut. An example of a conventional cutting guides is described in U.S. Pat. No. 6,925,724.
A substantial problem with conventional cutting guides can be that the surface(s) which engage the piece of material to be cut are substantially flat while the piece of material to be cut may include a seam along with a seam allowance which results in a raised portion in the material to be cut. Placing a conventional cutting guide on a seam, a seam allowance, or other raised area, point or support in the piece of material to be cut can cause a conventional cutting guide to wobble, pivot, or otherwise move in relation to the raised area in the piece of material.
Movement of the cutting guide in relation to a raised area in the piece of material to be cut results in corresponding movement of the side of the cutting guide along which the cutting tool engages to cut the piece of material. If the cutting guide shifts in position as the cutting tool cuts the piece of material a unintended irregularity can be created in the edge of the cut material. Additionally, movement of the cutting guide can result in disengagement of the cutting tool with the cutting guide. The cutting tool may then be free to travel across the material in an unintended direction or cut the hand of the cutting tool user.
Another substantial problem with conventional cutting guides can be that, there is no means other than visible marks on the cutting guide to assist in determining placement of the cutting guide on the piece of material to be cut. Typically, the placement of a conventional cutting guide on a piece of material to be cut is determined by matching visible marks on the cutting guide (or the corners of the cutting guide) with a stitching line or seam in the material to be cut. Additionally, once the placement of the cutting guide on the piece of material to be cut is determined there may be no cutting guide element to fix the placement of the cutting guide in relation to piece of material to be cut. As a result, determination of the location at which to place the conventional cutting guide may be uncertain and the cutting guide may move from the location before cutting of the piece of material is complete.
The inventive cutting guide with a seam allowance recess and inventive methods of using the inventive cutting guide with a seam allowance recess addresses each of the foregoing problems associated with conventional cutting guides and conventional methods of using a cutting guide.
II. SUMMARY OF THE INVENTION
Accordingly, a broad object of the invention can be to provide a cutting guide having a recess of sufficient dimension to receive a seam, a seam allowance, or other raised portion of a piece of material to be cut. The raised portion of the piece of material being received within the recess of the cutting guide reduces or eliminates any point or support on which the cutting guide can pivot or wobble and allows the cutting guide to engage the piece of material to be cut outside of a raised portion with greater uniformity.
A second broad object of the invention can be to provide a recess in a cutting guide of sufficient dimension to receive a seam allowance. The recess can further provide a pair of opposed sides one of which be located to abut the seam allowance to fix the location of the cutting guide in relation to the piece of material to be cut.
Naturally, further objects of the invention are disclosed throughout other areas of the specification, drawings, photographs, and claims.

IV. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A cutting guide (6) having a seam allowance (2) recess (13) and methods of cutting a piece of material (1) with such cutting guide (6).
Now referring primarily to FIG. 1, a particular method of cutting a piece of material (1) is illustrated. In one step the inventive method includes providing a piece of material (1) having a seam allowance (2) at which a pair of materials (3) join at a seam (4). The pair of materials (3) for the purposes of this invention means any manner of materials which can be joined by stitching or sewing (or other method such as application of heat or pressure) usually near the edge of the materials such as woven fabric whether of natural or synthetic fibers, leather, cloth, plastic, or the like. The area between the edge of the pair of materials (3) (or plurality of materials) and the stitching line or seam (4) is referred to herein as the seam allowance (2). The seam allowance (2) can range from about one-quarter inch wide (about 6.35 mm) to as much as several inches wide. Typically, however, the seam allowance (2) will have a range of about one-quarter inch and about five eighths inch. For the purposes of this invention the term “seam allowance (2)” also includes the flaps of material (5) between the edge of the pair of materials (3)(or plurality of materials) and the seam (4)(or stitching line) at which the pair of materials (3) (or plurality of materials) join. In another step of the inventive method, the flaps of material (5) can be folded or located on one side of the seam (4) at which the pair of materials (3)(or plurality of materials) join.
Again referring primarily to FIG. 1, the particular method of cutting a piece of material (1) can further include the step of providing a cutting guide (6). The cutting guide (6) can include (as further described below) a body (7) with a top surface (8) disposed in substantially parallel opposed relation to a bottom surface (9) having a thickness (10) sufficient to guide a cutting tool (11) along one of a plurality of sides (12) of the body (7). A recess (13) having a pair of opposed sides (14)(15) and a cross member (16) can be disposed in the bottom surface (9) (or top surface (8)) of the body (7) of the cutting guide (6). The recess (13) can define a passage (17) which communicates with at least one of the plurality of sides (12) of the body (7) of the cutting guide (6). The recess (13) can have dimensions sufficient to receive the seam allowance (2) of the pair of materials (3)(or plurality of materials) joined at the stitching line or seam (4) and as to certain embodiments the recess (13) can receive the seam allowance (2) with the flaps of the material (5) located or folded to one side of the seam (4).
Again referring primarily to FIG. 1, the particular method of cutting a piece of material (1) can further include the step of engaging the bottom surface (9) (or the top surface (8)) depending on which surface (8)(9) the recess (13) is disposed in) of the cutting guide (6) with the piece of material (1) such that the seam allowance (2) can be received within the recess (13) disposed in the cutting guide (6). By receiving the seam allowance (2) in the recess (13), the bottom surface (9) (or the top surface (8)) of the cutting guide (6) can engage the piece of material (1) on either side of the seam allowance (2). Particular embodiments of the method can further include the step of abutting one of the pair of opposed sides (14)(15) of the recess (13) against the seam (4) of the piece of material (1).
Again referring primarily to FIG. 1, the particular method of cutting a piece of material (1) can further include the step of guiding a cutting tool (11) along one or more of the plurality of sides (12) of the cutting guide (6) engaged with the piece of material (1) to receive the seam allowance (2) in the recess (13) and in a further step cutting the piece of material (1) extending beyond one or more of the plurality of sides (12) with the cutting tool (11) guided along one said plurality of sides (12) of the cutting guide (6).
Now referring primarily to FIGS. 2-5, which show a particular embodiment of an inventive cutting guide (6). The cutting guide (6) can include a body (7) having a top surface (8) disposed in substantially parallel opposed relation to a bottom surface (9) having a thickness (10) sufficient to guide a cutting tool (11)(as shown in FIG. 1 as an example) along one of a plurality of sides (12) of the body (7). The cutting guide (6) can further include a recess (13) having a pair of opposed sides (14)(15) with a cross member (16) coupled between the opposed sides (14)(15) disposed in the bottom surface (9) of said body (7), the recess (13) defining a passage (17) which communicates with at least one of the plurality of sides (12) of said body (7), the recess (13) having dimensions sufficient to receive a seam allowance (2) of a pair of materials (3) joined at a seam (4) with the bottom surface (9) engaged with the pair of materials (3) on either side of the seam allowance (2)(also see FIG. 1). As to a particular embodiment of the cutting guide (6) shown in FIGS. 2-5, the body can have substantially square or rectangular configuration. The body (7) can be generated from a wide and numerous variety of materials such as metal, plastic, wood, or the like. The recess (13) disposed in the bottom surface (9) or the top surface (8) of the cutting guide (6) can, as non-limiting examples, be generated by molding the cutting guide (6) with the recess (13) as one piece in a mold, fabricating the cutting guide (6) in two or more layers which can be assembled to provide the recess (13), or cutting the recess (13) into the body (7) by removing material from the body (7). The thickness (10) of the body (7) sufficient to guide a cutting tool (11) while typically in the range of about one eighth inch to about five eighths inch is not so limited, and depending upon the application, the body (7) can have a greater or lesser thickness (10). Similarly, while the opposing sides (14)(15) of the recess (13) will typically be located in opposed relation a distance apart (32) in the range of about one-quarter inch and about three quarters inch, the invention is not so limited, and depending upon the application the opposing sides (14)(15) of the recess can be a greater or lesser distance (32) apart. The opposed sides (14)(15) will typically connect with the bottom surface (9) (or the top surface (8)) of the body (7) in substantially perpendicular relation and further connect with the cross member (16) in substantially perpendicular relation to provide a recess (13) of open square or rectangular configuration. The depth (18) of the recess (13) will typically be in a range of about one sixteenth inch and about five sixteenths inch; however, the invention is not so limited, and the dimensional relations of the recess (13) can be adjusted such that the seam allowance (2) (typically comprising the thickness of the two flaps of material (5) folded to one side of the seam (4) and the thickness of the joined material (3)) can be received within the recess (13) coincident with engagement of the bottom surface (9) (or the top surface (8)) with the surface of the joined pair of materials (3). Locating the seam allowance (2) within the recess (13) allows one of the surfaces (8)(9) of the cutting guide (6) to engage the joined pair of materials (3) without the seam allowance (2) acting as a point or support on which the cutting guide (6) pivots, wobbles or otherwise prevents fixed engagement of the cutting guide (6) with the joined pair of materials (3)(see also FIG. 1).
Again referring primarily to FIGS. 2-8, particular embodiments of the cutting guide (6) shown further includes a recess (13) which defines a passage (17) which communicates between at least two of the plurality of sides (12) of the body (7). Where the body (7) has a substantially rectangular configuration with two pairs of opposed sides (19)(20) and a corresponding two pairs of diagonally opposed corners (21)(22) the recess (13) can define a passage (17) which communicates between one of the two pairs of diagonally opposed corners (21)(22) of the body (7). Referring specifically to FIGS. 7 and 8, as to particular embodiments, the pair of opposed sides (14)(15) of the recess (13) can be located a distance from the diagonal axis (23) which runs between diagonally opposed corners (21) (broken line shown in FIG. 7 as an example). Now referring specifically to FIGS. 2-5, as to other embodiments of the invention, one of the opposed sides (14) of the recess (13) can intersect with both of the diagonally opposed corners (21) such that the longitudinal midline (33) of the recess (13) communicates with at least one of the plurality of sides (12) of the body (7).
Now referring primarily to FIGS. 9 and 10, which shows a particular embodiment of the cutting guide (6) which provides a body (7) having a substantially rectangular configuration with two pairs of opposed sides (19)(20) in which the recess (13) disposed in the bottom surface (9) defines a passage (17) which communicates between one of the two pairs of opposed sides (19) of said body (7).
Each of the embodiments of the invention shown in FIGS. 1-8 provide a recess (13) having substantially linear parallel opposed sides (24); however, the invention is not so limited and as shown for example in FIGS. 11-12 the recess (13) as to certain embodiments can provide opposed sides (14)(15) having an amount of curvature (25).
Now referring primarily to FIGS. 13-18, certain embodiments of the invention can further include a second recess (26) having a pair of opposed sides (14)(15) and a cross member (16) disposed in the bottom surface (9) of the body (7) (or the top surface (8)). The second recess (26) can have dimensions sufficient to receive the seam allowance (2) of a pair of materials (3) joined at a seam (4) with said bottom surface (9) engaged with said pair of materials (3) on either side of said seam allowance (2). As to the embodiment shown in FIGS. 13-14, the second recess (26) defines a second passage (27) which can communicate between said first recess (13) and at least one of said plurality of sides (12) of the body (7). Extending the second recess (26) would result in an embodiment which defines a second passage (27) which communicates with the first recess (13) and two of the plurality of sides (12) of the body (7). Certain embodiments can provide the body (7) having a substantially rectangular configuration with two pairs of opposed sides (19)(20) and a corresponding two pairs of diagonally opposed corners (21)(22) in which the second recess (26) defines a passage which communicates between one of the two pairs of opposed sides (19) and the first recess (13) communicates between the second of the two pairs of opposed sides (20) (not shown). Again, certain embodiments can provide a second recess (26) which defines a passage (27) which communicates between one of said two pairs of diagonally opposed corners (21)(22). One of said opposed sides (14) of the second recess (26) which communicates between one of said two pairs of diagonally opposed corners (21) of the body can intersect both of said diagonally opposed corners (21).
Now referring primarily to FIGS. 15 and 16, certain embodiments of the invention can provide a first recess (13) and a second recess (27) disposed on opposed sides of the body (7) of the cutting guide (6). Each of the first recess (13) and the second recess (27) can have a pair of opposed sides (14)(15) and a cross member (16) defining a first passage (17) and a second passage (27) each of which communicates with at least one of said plurality of sides (12) of said body (7) with each recess (13)(27) having dimensions sufficient to receive a seam allowance (2) of a pair of materials (3) joined at a seam (4) with the corresponding top surface (8) or bottom surface (9) engaged with said pair of materials (3) on either side of said seam allowance (2). While the embodiment shown in FIGS. 15 and 16, show the first recess (13) and the second recess (27) disposed in the opposed top and bottom surfaces (7)(8) having substantially the same overlaying configuration; the invention is not so limited, and the first recess (13) can have substantially different configuration or placement on the top surface (8) than the second recess (27) disposed in the bottom surface (9).
Now referring primarily to FIGS. 17 and 18, certain embodiments of the inventive cutting guide (6) can provide a elongate rectangular body (7) having a thickness sufficient to guide a cutting tool (11)(as shown in FIG. 1) along one of a plurality of sides (12) of the body (7). A plurality of recesses (28) having a pair of opposed sides (19)(20) and a cross member (16) can be disposed in the bottom surface (9)(or the top surface (8) or both surfaces) of the body (7). Each of the plurality of recesses (28) can define a corresponding plurality of a passages (29) which communicates between opposed sides (30)(31) of the body (7). Each of the plurality of recesses (28) can have dimensions sufficient to receive a seam allowance (2) of a pair of materials (3) joined at a seam (4) with the corresponding surface (8)(9) engaged with said pair of materials (3) on either side of said seam allowance (2).
As to each of the examples of the inventive cutting guides (6) shown in the Figures, the bottom surface (9) or the top surface (8) or both can further include graphic indicia or numeric indicia (not shown) imprinted or applied to the surface for instruction, placement or measurement.
