[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings.

[0019] [First embodiment] 1 to 7, a pattern cutting aid (hereinafter referred to as "aid A10") according to a first embodiment of the present invention will be described. Aid A10 comprises a guide member 10, a first holding body 21, a second holding body 22, two protrusions 23, a restoring force generating means 30, and a cover 40. Aid A10 is made of a material containing resin, except for the restoring force generating means 30. However, the material of aid A10 is not limited to this.

[0020] In the description of the auxiliary tool A10, the direction in which the first holder 21 protrudes from the guide member 10 is referred to as the "first direction Z." The direction perpendicular to the first direction Z is referred to as the "second direction X." The direction perpendicular to the first direction Z and the second direction X is referred to as the "third direction Y."

[0021] 1 and 2, the guide member 10 extends in the second direction X. The guide member 10 is made of a transparent resin material, for example, including polycarbonate. The guide member 10 is provided with a slit 11, a cutting reference portion 12, a plurality of positioning portions 13, a groove 14, and a plurality of support holes 15.

[0022] As shown in FIG. 5 , the slit 11 penetrates the guide member 10 in the first direction Z. The slit 11 extends in the third direction Y. The guide member 10 has a first surface 101 and a third surface 102 facing the third direction Y. The first surface 101 and the third surface 102 define the slit 11. The first surface 101 and the third surface 102 face each other.

[0023] 2, when viewed in the first direction Z, the slit 11 is connected to the first holding body 21. As a result, the guide member 10 has a boundary 103 that is a border between the slit 11 and the first holding body 21. The boundary 103 is two points located on opposite sides of the slit 11 in the third direction Y.

[0024] 2, the position of the cutting reference portion 12 in the second direction X is equal to the position of the boundary 103 in the second direction X. In the assisting tool A10, the cutting reference portion 12 includes two lines positioned on opposite sides of the slit 11 in the third direction Y. The two lines extend in the third direction Y and reach both edges of the guide member 10 in the third direction Y.

[0025] As shown in FIG. 2, the multiple positioning portions 13 are located away from the slit 11 in the second direction X. All of the multiple positioning portions 13 are located on the opposite side of the slit 11 in the second direction X with the first holder 21 as the reference. Each of the multiple positioning portions 13 is spaced a predetermined distance from the cutting reference portion 12 in the second direction X. In the assisting device A10, one of the multiple positioning portions 13 includes a line extending in the third direction Y. The multiple positioning portions 13 reach both edges of the guide member 10 in the third direction Y.

[0026] 2, the plurality of positioning portions 13 include two, a first positioning portion 131 and a second positioning portion 132. However, the number of the plurality of positioning portions 13 is not limited to this and can be freely set. The second positioning portion 132 is located between the first holder 21 and the first positioning portion 131 in the second direction X.

[0027] 6 and 7, groove 14 is recessed in first direction Z on the side opposite to the side where first holding body 21 protrudes from guide member 10, and extends in second direction X. Groove 14 is located on the opposite side of first holding body 21 with slit 11 as the reference in second direction X. Groove 14 is connected to slit 11.

[0028] 3, the plurality of support holes 15 are positioned around the groove 14 when viewed in the first direction Z. The plurality of support holes 15 penetrate the guide member 10 in the first direction Z.

[0029] As shown in FIGS. 1 and 4 , the first holding body 21 protrudes from the guide member 10 in the first direction Z as described above. The first holding body 21 is located between the slit 11 and the plurality of positioning portions 13 in the second direction X. In the auxiliary tool A10, the first holding body 21 is integrally molded with the guide member 10. Therefore, the material of the first holding body 21 is the same as the material of the guide member 10. Alternatively, the first holding body 21 may be joined to the guide member 10 and made of a material different from that of the guide member 10.

[0030] 2, 4, and 7, the first holding body 21 has a first holding surface 211. The first holding surface 211 faces the side facing the second holding body 22 in the second direction X.

[0031] As shown in Figures 1 and 2, second holder 22 is located on the opposite side of first holder 21 from the multiple positioning portions 13 in second direction X. Second holder 22 faces first holder 21. Second holder 22 is made of a resin material containing, for example, ABS resin. As shown in Figures 2 and 7, second holder 22 has a base portion 221, a lever portion 222, and a connecting portion 223.

[0032] 6 and 7, the base 221 is disposed in the groove 14 of the guide member 10. The base 221 is slidable along the groove 14 in the second direction X. The base 221 has a second holding surface 221A. The second holding surface 221A faces the first holding surface 211 of the first holding body 21.

[0033] 5 to 7, lever portion 222 protrudes from base portion 221 in the first direction Z on the side where first holding body 21 protrudes from guide member 10. Lever portion 222 is located closer to restoring force generating means 30 than first holding body 21 in the second direction X.

[0034] 2 and 7, the connecting portion 223 protrudes from the base portion 221 on the side opposite to the side facing the first holding body 21 in the second direction X. The connecting portion 223 is adjacent to the lever portion 222.

[0035] As described above, the base 221 is slidable in the second direction X along the groove 14 of the guide member 10, and therefore the second holder 22 is movable in the second direction X. When the second holder 22 is moved in the second direction X toward the first holder 21, the second holder 22 moves to a position where the second holding surface 221A of the base 221 can come into contact with the first holding surface 211 of the first holder 21. As shown in FIGS. 2 and 3 , when the second holding surface 221A is brought into contact with the first holding surface 211, the base 221 overlaps with the slit 11 of the guide member 10 as viewed in the first direction Z.

[0036] 1 and 4, the two protrusions 23 protrude from the guide member 10 in the first direction Z on the side where the first holding body 21 protrudes from the guide member 10. The dimension of each of the two protrusions 23 in the first direction Z is smaller than the dimension of the first holding body 21 in the first direction Z. In the auxiliary tool A10, the two protrusions 23 are integrally molded with the guide member 10. Therefore, the material of the two protrusions 23 is the same as the material of the guide member 10.

[0037] 2, the two protrusions 23 include a first protrusion 231 and a second protrusion 232. The first protrusion 231 and the second protrusion 232 are located on opposite sides of the first holder 21 in the third direction Y. Furthermore, the first protrusion 231 and the second protrusion 232 are located at the boundary 103 of the guide member 10. The first protrusion 231 is located closer to the third surface 102 of the guide member 10 than to the first surface 101 of the guide member 10 in the third direction Y. Therefore, the first surface 101 is located on the opposite side of the first protrusion 231 from the first protrusion 231 in the third direction Y with respect to the first holder 21.

[0038] 5, the first protrusion 231 has a second surface 231A positioned away from the guide member 10. The second surface 231A is inclined toward the slit 11 in the first direction Z as it approaches the first surface 101 of the guide member 10 in the third direction Y. The inclination angle of the second surface 231A with respect to the third direction Y is, for example, 30°.

[0039] As shown in Figure 5, when viewed in the second direction X, a first extension line L1 extending from the first surface 101 of the guide member 10 and a second extension line L2 extending from the second surface 231A of the first protrusion 231 intersect at an intersection P1 on the opposite side of the slit 11 of the guide member 10 from the side on which the first retaining body 21 is located in the first direction Z.

[0040] 5, the second protrusion 232 has a fourth surface 232A positioned away from the guide member 10. The fourth surface 232A is inclined toward the slit 11 in the first direction Z as it approaches the third surface 102 of the guide member 10 in the third direction Y. The inclination angle of the fourth surface 232A with respect to the third direction Y is, for example, 30°.

[0041] As shown in Figure 5, when viewed in the second direction X, the third extension line L3 extending from the third surface 102 of the guide member 10 and the fourth extension line L4 extending from the fourth surface 232A of the second protrusion 232 intersect at an intersection P2 on the opposite side of the slit 11 of the guide member 10 from the side on which the first retaining body 21 is located in the first direction Z.

[0042] As shown in FIGS. 1, 2, and 7, the restoring force generating means 30 is located on the opposite side of the first holding body 21 with respect to the second holding body 22. The restoring force generating means 30 is in contact with the second holding body 22. When the second holding body 22 is moved in the second direction X away from the first holding body 21, the restoring force generating means 30 generates a restoring force in the second direction X toward the first holding body 21. This restoring force causes the second holding body 22 to move to a position where it can contact the first holding body 21. Furthermore, when the second holding surface 221A of the base 221 of the second holding body 22 contacts the first holding surface 211 of the first holding body 21, a compressive force in the second direction X acts on the first holding surface 211, and a reaction force to this compressive force acts on the second holding surface 221A. As a result, the first holding surface 211 and the second holding surface 221A press against each other.

[0043] In the assisting device A10, the restoring force generating means 30 is a coil spring that can be compressed in the second direction X. The coil spring is made of, for example, stainless steel. One end of the coil spring is inserted into the connecting portion 223 of the second holding body 22. This brings the restoring force generating means 30 into contact with the second holding body 22 and into a state where it is held by the second holding body 22.

[0044] As shown in Figs. 5 to 7, the cover 40 covers a portion of the guide member 10. The base portion 221 and the connecting portion 223 of the second holding body 22 and the restoring force generating means 30 are housed in the cover 40. The cover 40 is made of a resin material containing, for example, ABS resin. As shown in Fig. 4, the cover 40 has a main portion 41, a wall portion 42, and a plurality of support portions 43.

[0045] As shown in FIGS. 1 and 2, the main portion 41 extends in the second direction X. The base portion 221 and the connecting portion 223 of the second holding body 22 and the restoring force generating means 30 are covered by the main portion 41. As shown in FIG. 7, the main portion 41 has an opening 411 and an inner surface 412. As shown in FIGS. 5 to 7, the opening 411 penetrates the main portion 41 in the first direction Z. The opening 411 extends in the second direction X. The lever portion 222 of the second holding body 22 is inserted through the opening 411. The lever portion 222 is exposed to the outside through the opening 411. As shown in FIG. 7, the inner surface 412 is located on the opposite side of the base portion 221 of the second holding body 22 with respect to the restoring force generating means 30 in the second direction X. The inner surface 412 faces the restoring force generating means 30. The restoring force generating means 30 is in contact with the inner surface 412.

[0046] 1 and 4, the wall portion 42 protrudes from the main portion 41 in the first direction Z on the side where the first holder 21 protrudes from the guide member 10. The wall portion 42 is located on the opposite side of the first holder 21 with respect to the second holder 22 in the second direction X. The wall portion 42 faces the lever portion 222 of the second holder 22.

[0047] 4, the plurality of support portions 43 protrude from the main portion 41 on the side opposite to the side where the first holder 21 protrudes from the guide member 10 in the first direction Z. As shown in FIG. 3, the plurality of support portions 43 are individually inserted into the plurality of support holes 15 of the guide member 10. This allows the cover 40 to be held by the guide member 10.

[0048] Next, the use state of the assisting tool A10 will be described with reference to FIGS.

[0049] First, as shown in FIGS. 8 and 9 , the auxiliary tool A10 is attached to the blade 50. The blade 50 is one of various commercially available cutter knives. The auxiliary tool A10 is attached in the following manner. First, the lever portion 222 of the second holder 22 and the wall portion 42 of the cover 40 are firmly pinched with the fingers to move the second holder 22 away from the first holder 21 in the second direction X. Next, the blade 50 is inserted into the slit 11 of the guide member 10 and brought into contact with the first holding surface 211 of the first holder 21. Finally, when the fingers are released from the lever portion 222 and the wall portion 42, the second holder 22 moves toward the first holder 21 due to the restoring force of the restoring force generating means 30, and the second holding surface 221A of the base portion 221 of the second holder 22 comes into contact with the blade 50. As a result, a compressive force in the second direction X acts on the blade 50, and the blade 50 is sandwiched between the first holding surface 211 and the second holding surface 221A. This completes the attachment of the assisting tool A10.

[0050] Next, as shown in Fig. 8, one of the multiple positioning portions 13 of the guide member 10 is aligned with the finished line 61 of the paper pattern 60. In the example shown in Fig. 8, the first positioning portion 131 is aligned with the finished line 61. In this state, when the paper pattern 60 is cut with the blade 50 while the auxiliary tool A10 is moved along the finished line 61 so that the first positioning portion 131 does not deviate from the finished line 61, cutting lines 62 are formed on the paper pattern 60 and equally spaced seam allowances 63 are set on the paper pattern 60. At this time, the cutting reference portion 12 of the guide member 10 passes over the cutting line 62.

[0051] As shown in Fig. 9, when the assisting tool A10 is attached to the blade 50, the blade 50 can be supported by either of the two protrusions 23. The example shown in Fig. 9 is a case where the blade 50 is supported by the first protrusion 231. In this case, the blade 50 contacts the second surface 231A of the first protrusion 231. In this state, when the blade 50 is moved in the third direction Y toward the second protrusion 232, the blade 50 contacts the first surface 101 of the guide member 10. At this time, when viewed in the second direction X, the tip of the blade 50 substantially coincides with the position of the intersection P1 between the first extension line L1 and the second extension line L2.

[0052] 9 , when the blade 50 is supported by the second protrusion 232, the blade 50 comes into contact with the fourth surface 232A of the second protrusion 232. When the blade 50 is moved in this state toward the first protrusion 231 in the third direction Y, the blade 50 comes into contact with the third surface 102 of the guide member 10. At this time, when viewed in the second direction X, the tip of the blade 50 substantially coincides with the position of the intersection P2 of the third extension line L3 and the fourth extension line L4.

[0053] Next, the function and effect of the assisting tool A10 will be described.

[0054] The assisting tool A10 includes a guide member 10 provided with a slit 11 and a first positioning portion 131, a first holder 21 protruding from the guide member 10 in the first direction Z, and a second holder 22 facing the first holder 21. The first holder 21 is positioned between the slit 11 and the first positioning portion 131 in the second direction X. The second holder 22 is positioned on the opposite side of the first positioning portion 131 relative to the first holder 21 in the second direction X, and is movable in the second direction X to a position where it can contact the first holder 21. When the second holder 22 is brought into contact with the first holder 21, the second holder 22 overlaps the slit 11 as viewed in the first direction Z. With this configuration, the blade 50 can be inserted through the slit 11 and then sandwiched between the first holder 21 and the second holder 22. This allows the auxiliary tool A10 to be attached to the blades 50 of various cutter knives. Furthermore, as shown in Fig. 8, when the first positioning portion 131 is aligned with the finished line 61 of the paper pattern 60 and the auxiliary tool A10 is moved along the finished line 61 while cutting the paper pattern 60 with the blade 50, it is possible to set evenly spaced seam allowances 63 on the cut paper pattern 60. Therefore, with the auxiliary tool A10, it is possible to cut the paper pattern 60 after setting evenly spaced seam allowances 63, and by being attachable to various blades 50, it is possible to improve convenience.

[0055] The auxiliary tool A10 further includes a restoring force generating means 30 that is located on the opposite side of the first holder 21 with respect to the second holder 22 in the second direction X and that contacts the second holder 22. With this configuration, the second holder 22 can be pressed against the first holder 21 by the restoring force of the restoring force generating means 30. This allows the blade 50 to be firmly sandwiched between the first holder 21 and the second holder 22 with a relatively simple structure.

[0056] The assisting device A10 further includes a cover 40 that covers a portion of the guide member 10 and houses the restoring force generating means 30. The second holding body 22 has a base 221 housed in the cover 40 and a lever portion 222 that protrudes from the base 221 on the side from which the first holding body 21 protrudes in the first direction Z. The lever portion 222 protrudes to the outside through an opening 411 provided in the cover 40. With this configuration, even when the base 221 is housed in the cover 40, the second holding body 22 can be moved in the second direction X by pressing a finger against the lever portion 222.

[0057] The cover 40 has an inner surface 412 facing the restoring force generating means 30. The restoring force generating means 30 is in contact with the inner surface 412. With this configuration, the inner surface 412 serves as a fixed end of the restoring force generating means 30, so that even when the second holding body 22 is moved in the second direction X away from the first holding body 21, a compressive force in the second direction X can be introduced into the restoring force generating means 30. This ensures that a restoring force is generated in the restoring force generating means 30.

[0058] The guide member 10 is provided with a groove 14 that is recessed on the side opposite to the side from which the first holding body 21 protrudes in the first direction Z and extends in the second direction X. The base 221 of the second holding body 22 is disposed in the groove 14. With this configuration, when the second holding body 22 moves in the second direction X, the movement of the second holding body 22 in the third direction Y can be restricted.

[0059] Auxiliary tool A10 has a first protrusion 231 that protrudes from guide member 10 on the side from which first holder 21 protrudes in first direction Z. First protrusion 231 is located at boundary 103 between first holder 21 and slit 11 of guide member 10 in second direction X. With this configuration, when blade 50 is inserted into slit 11, blade 50 is supported by first protrusion 231, thereby preventing portions of guide member 10 located around slit 11 from being damaged by blade 50.

[0060] The guide member 10 has a first surface 101 that faces the third direction Y and defines the slit 11. The first surface 101 is located on the opposite side of the first protrusion 231 in the third direction Y with the first holder 21 as the reference. The first protrusion 231 has a second surface 231A that is located away from the guide member 10 in the first direction Z. The second surface 231A is inclined more toward the slit 11 in the first direction Z as it approaches the first surface 101 in the third direction Y. With this configuration, when the blade 50 is brought into contact with the entire second surface 231A, the blade 50 can be maintained in an attitude inclined at a predetermined angle with respect to the third direction Y when the assisting tool A10 is attached to the blade 50 (see FIG. 9 ).

[0061] As viewed in the second direction X, a first extension line L1 extending from the first surface 101 of the guide member 10 and a second extension line L2 extending from the second surface 231A of the first protrusion 231 intersect in the first direction Z on the side opposite to the side on which the first holder 21 is located, with the slit 11 of the guide member 10 as the reference. With this configuration, as shown in Fig. 9, the first surface 101 restricts the movement of the blade 50 in the third direction Y, and can also restrict the amount of protrusion of the blade 50 from the slit 11 on the side opposite to the side on which the first holder 21 protrudes in the first direction Z.

[0062] The guide member 10 is provided with a second positioning portion 132 located between the first holding body 21 and the first positioning portion 131 in the second direction X. By adopting this configuration, the equally spaced seam allowances 63 set on the pattern 60 can be selected from a plurality of dimensions.

[0063] Second Embodiment A pattern cutting aid according to a second embodiment of the present invention (hereinafter referred to as "aid A20") will be described with reference to Figure 10. In these figures, elements that are the same as or similar to the above-described aid A10 are given the same reference numerals, and duplicated explanations will be omitted.

[0064] In the assisting tool A20, the configuration of the guide member 10 is different from that of the assisting tool A10.

[0065] 10, the guide member 10 is formed with a window 16 that penetrates in the first direction Z and extends in the second direction X. The window 16 is located on the opposite side of the first holder 21 from the slit 11 of the guide member 10 in the second direction X. Each of the multiple positioning portions 13 is divided into two in the third direction Y with the window 16 as the reference.

[0066] Next, the function and effect of the assisting tool A20 will be described.

[0067] The auxiliary tool A20 includes a guide member 10 having a slit 11 and a first positioning portion 131, a first holder 21 protruding from the guide member 10 in the first direction Z, and a second holder 22 facing the first holder 21. The first holder 21 is located between the slit 11 and the first positioning portion 131 in the second direction X. The second holder 22 is located on the opposite side of the first holder 21 from the first positioning portion 131 in the second direction X, and is movable in the second direction X to a position where it can contact the first holder 21. When the second holder 22 is brought into contact with the first holder 21, the second holder 22 overlaps the slit 11 as viewed in the first direction Z. Therefore, the auxiliary tool A20 also makes it possible to cut the pattern 60 after setting equally spaced seam allowances 63, and by being attachable to various blades 50, it is possible to improve convenience. Furthermore, the assisting tool A20 has the same configuration as the assisting tool A10, and thus has the same effects as the assisting tool A10.

[0068] In the auxiliary tool A20, a window 16 is provided in the guide member 10. Each of the plurality of positioning portions 13 is divided into two in the third direction Y with the window 16 as a reference. With this configuration, the finished line 61 of the paper pattern 60 can be seen through the window 16. This allows any of the plurality of positioning portions 13 to be aligned with the finished line 61 with high precision.

[0069] The present invention is not limited to the above-described embodiment, and the specific configuration of each part of the present invention can be freely designed and modified in various ways. [Explanation of symbols]
