Summary of the Invention

[0007] Incidentally, in the case of the scissors described in Patent Document 1, the center of each insertion hole of the multiple attachments is the same as the center of the through hole. Also, if the attachment is composed of multiple divided parts, the center of each of the multiple divided parts is the same as the center of the through hole. Therefore, the smaller the size of the insertion holes of the attachments attached to a pair of handles, the larger the distance between the insertion holes becomes, and the larger the distance between the user's thumb and index or middle finger inserted into the two insertion holes. As a result, there is a problem that the scissors become less convenient to use for users with small hands. Furthermore, if a user is wearing gloves such as work gloves, which increases the actual size of the fingers inserted into the insertion holes, and then removes the gloves, the size of the fingers inserted into the insertion holes decreases, the scissors become less convenient to use. [Means for solving the problem]

[0008] The following describes various types of scissors designed to solve the above problems. [Aspect 1] A pair of blades, a connecting shaft that connects the pair of blades so that they can be opened and closed, and a pair of handles provided at the base ends of the pair of blades, each having an insertion hole through which the user's fingers can be inserted, The device comprises an attachment that is detachably mounted on the inner circumferential surface of the insertion hole of at least one of the pair of handle portions, and which adjusts the size of the insertion hole, When the portion of one of the handles to which the attachment is attached is adjacent to the other handle portion when the pair of blades are closed, The attachment is provided on the portion of the inner circumferential surface excluding the portion on the adjacent side. scissors.

[0009] According to this configuration, the size of the insertion hole can be reduced by attaching an attachment to the inner circumferential surface of the insertion hole. Furthermore, the attachment is not provided on the adjacent portion of the inner circumferential surface of the insertion hole. Therefore, while reducing the size of the insertion hole by attaching the attachment, it is possible to suppress the increase in the distance between the user's thumb and index or middle finger. Thus, it is possible to improve usability while reusing the scissor body.

[0010] [Aspect 2] The attachment is formed of an elastic material. The scissors described in Embodiment 1.

[0011] According to this configuration, the attachment can be easily attached to and detached from the inner circumferential surface of the insertion hole in the handle by elastically deforming the attachment. [Aspect 3] The aforementioned handle portion is A handle body having a through hole, It includes an annular member having the aforementioned insertion hole and provided so as to cover the inner circumferential surface of the through hole, The attachment is configured to be detachably attached to the annular member. The scissors described in Embodiment 1 or Embodiment 2.

[0012] According to this configuration, by using a different material for the ring-shaped component than the handle body, it becomes possible to provide a different tactile feel to the part that touches the user's fingers when using the scissors without attaching an attachment.

[0013] [Aspect 4] When the aforementioned attachment is referred to as the first attachment, The first attachment is detachably attached to the inner circumferential surface and includes a second attachment for adjusting the size of the insertion hole. Scissors as described in any one of Embodiments 1 to 3.

[0014] According to the same configuration, by attaching the second attachment to the inner peripheral surface of the first attachment, the size of the insertion hole can be further reduced. This can improve the usability for smaller-handed users.

[0015] [Aspect 5] On the inner peripheral surface of the insertion hole, a fitting portion extending along the circumferential direction of the insertion hole is provided. On the outer peripheral surface of the attachment, a fitting groove extending along the fitting portion and fitting into the fitting portion is provided. The scissors according to Aspect 2.

[0016] Since the attachment is formed of an elastic material, the attachment can be easily attached to and detached from the inner peripheral surface of the insertion hole. On the other hand, when an external force acts on the attachment and the attachment elastically deform, it becomes easier to drop off from the handle portion.

[0017] In this regard, according to the above configuration, by fitting the fitting portion provided on the inner peripheral surface of the insertion hole and the fitting groove provided on the outer peripheral surface of the attachment, the detachment of the attachment from the handle portion can be suppressed.

[0018] [Aspect 6] When the fitting portion is used as the first fitting portion and the fitting groove is used as the first fitting groove, a second fitting portion extending along the circumferential direction of the insertion hole is provided in the first fitting portion. In the first fitting groove, a second fitting groove extending along the second fitting portion and fitting into the second fitting portion is provided. The scissors according to Aspect 5.

[0019] According to the same configuration, in addition to the fitting of the first fitting portion and the first fitting groove, the second fitting portion and the second fitting groove are also fitted. This can further suppress the detachment of the attachment from the handle portion.

[0020] [Aspect 7] A pair of blades, a connecting shaft that connects the pair of blades so that they can be opened and closed, and a pair of handles provided at the base ends of the pair of blades, each having a through hole, It comprises an annular attachment having an insertion hole through which the user's fingers can be inserted, and which is detachably configured to be attached to the inner circumferential surface of the through hole of at least one of the pair of handle portions, When the portion of one of the handles to which the attachment is attached is adjacent to the other handle portion when the pair of blades are closed, The center of the insertion hole is located closer to the adjacent portion than the center of the through hole into which the attachment is mounted. scissors.

[0021] With this configuration, the size of the hole through which the fingers are inserted can be reduced by attaching an attachment to the inner circumferential surface of the through hole. Furthermore, the center of the attachment's insertion hole is positioned closer to the adjacent part than the center of the through hole in the handle to which the attachment is attached. Therefore, while reducing the size of the hole through which the fingers are inserted by attaching the attachment, it is possible to suppress the widening of the gap between the user's thumb and index or middle finger. Thus, the usability can be improved to a suitable degree while reusing the scissor body.

[0022] [Aspect 8] When the aforementioned attachment is designated as the first attachment and the aforementioned insertion hole as the first insertion hole, It has a second insertion hole through which the user's fingers can be inserted, and a second annular attachment detachably configured on the inner circumferential surface of the first insertion hole, The center of the second insertion hole is located closer to the adjacent portion than the center of the through hole into which the second attachment is mounted. The scissors described in Embodiment 7.

[0023] According to this configuration, by attaching the second attachment to the inner circumferential surface of the first insertion hole, the size of the hole through which the fingers are inserted can be further reduced. Furthermore, the center of the insertion hole of the second attachment is located closer to the adjacent part than the center of the through hole. Therefore, while further reducing the size of the hole through which the fingers are inserted by attaching the second attachment, it is possible to suppress the increase in the distance between the user's thumb and index or middle finger. [Effects of the Invention]

[0024] According to the present invention, it is possible to improve the user-friendliness of the scissors while still utilizing the existing scissor body. [Brief explanation of the drawing]

[Figure 10] Figure 10 is a plan view centered on the first handle portion of the scissors according to the second embodiment. [Figure 11] Figure 11 is a plan view showing the first handle portion of Figure 10 with the attachment mounted. [Modes for carrying out the invention]

[0026] <First Embodiment> The first embodiment will be described below with reference to Figures 1 to 9. As shown in Figure 1, the scissors 10 comprises a scissor body 11, first attachments 40, 60, and second attachments 50, 70.

[0027] <Scissors body 11> As shown in Figure 1, the scissors body 11 has a well-known configuration and comprises a pair of blades 12, 13 (first blade 12, second blade 13), a connecting shaft 14, a first handle 20, and a second handle 30.

[0028] The connecting shaft 14 connects the first blade 12 and the second blade 13 so that they can be opened and closed relative to each other. The first handle portion 20 is provided at the base end of the first blade 12 and has an insertion hole 24 through which the user's fingers (for example, thumb) can be inserted.

[0029] The second handle portion 30 is provided at the base end of the second blade 13 and has an insertion hole 34 through which the user's fingers (for example, the index finger and middle finger) can be inserted. As shown in Figures 4 to 6, the first handle portion 20 comprises a handle portion body 21 having a through hole 22 and an annular member 23 having an insertion hole 24 and provided to cover the inner circumferential surface 22a of the through hole 22.

[0030] In the following, the portion of the first handle portion 20 that is adjacent to the second handle portion 30 when the pair of blades 12 and 13 are closed is referred to as the adjacent portion 25. (Handle body 21) As shown in Figures 5 and 6, the through-hole 22 has a roughly semicircular shape in plan view.

[0031] The inner circumferential surface 22a of the through hole 22 has a portion that extends toward the adjacent portion 25 along the longitudinal direction of the scissors 10 (left-right direction in Figure 5). A first projection 22A is formed on the inner circumferential surface 22a of the through hole 22, projecting inward along the entire circumference of the through hole 22. A second projection 22B is provided on the portion of the first projection 22A excluding the adjacent portion 25, projecting inward and extending along the circumferential direction of the through hole 22.

[0032] The handle body 21 is formed of, for example, a hard resin. (Annular member 23) As shown in Figures 4, 7, and 9, the annular member 23 has a roughly semicircular shape in plan view.

[0033] As shown in Figures 7 and 9, a first groove 23A is formed on the outer circumferential surface 23a of the annular member 23, extending along the circumferential direction of the annular member 23 and fitting into the first protruding portion 22A of the handle body 21. The first groove 23A is provided around the entire circumference of the annular member 23.

[0034] The first groove 23A is provided with a second groove 23B that extends along the circumferential direction of the annular member 23 and fits into the second protruding portion 22B of the handle body 21. The second groove 23B is located in the center of the annular member 23 in the width direction and is provided in the portion corresponding to the second protruding portion 22B in the circumferential direction.

[0035] As shown in Figures 7(b) and 7(c), the width of the first groove 23A is greatest on the adjacent portion 25 side and gradually decreases as it moves away from the adjacent portion 25. The width of the second groove 23B gradually increases as it approaches both ends in the extending direction of the second groove 23B.

[0036] As shown in Figures 4, 7, and 9, a first fitting portion 24A is formed on the inner circumferential surface 24a of the through hole 24, extending along the circumferential direction of the through hole 24. The first fitting portion 24A is provided around the entire circumference of the through hole 24.

[0037] The first fitting portion 24A is provided with a second fitting portion 24B that protrudes inward and extends along the circumferential direction of the insertion hole 24. The second fitting portion 24B is located in the center of the annular member 23 in the width direction and is provided in the portion corresponding to the second protruding portion 22B in the circumferential direction.

[0038] As shown in Figure 7(a), the width of the first fitting portion 24A is greatest on the adjacent portion 25 side and gradually decreases as it moves away from the adjacent portion 25. The width of the second fitting portion 24B gradually increases as it approaches both ends in the extending direction of the second fitting portion 24B.

[0039] As shown in Figure 9, the first fitting portion 24A is curved such that the outer part of the insertion hole 24 is located closer to the outer circumference of the insertion hole 24 in the axial direction of the insertion hole 24 (up and down direction in Figure 9). The annular member 23 is formed from an elastic material such as an elastomer.

[0040] The outer circumferential surface 23a of the annular member 23 is joined to the inner circumferential surface 22a of the through hole 22. In this embodiment, the annular member 23 is integrally formed with the handle body 21 by insert molding. As shown in Figures 1 to 5, the second handle portion 30 has a handle body 31 and an annular member 33 similar to the handle body 21 of the first handle portion 20. Therefore, to avoid redundant explanations, each component of the second handle portion 30 is assigned a code that is the same as the code "2*" of the corresponding component of the first handle portion 20 plus "10".

[0041] <First attachment 40, 60> As shown in Figures 3, 8, and 9, the first attachment 40 adjusts the size of the insertion hole 24 and is detachably attached to the inner circumferential surface 24a of the insertion hole 24 of the first handle portion 20. In other words, the first attachment 40 is detachably attached to the annular member 23.

[0042] The first attachment 40 is provided on the inner circumferential surface 24a of the insertion hole 24, excluding the portion that constitutes the adjacent portion 25. In this embodiment, the first attachment 40 has a substantially arc shape when viewed from above.

[0043] As shown in Figures 8 and 9, the outer circumferential surface 41 of the first attachment 40 is provided with a first fitting groove 41A that extends along the first fitting portion 24A and fits into the first fitting portion 24A.

[0044] The first fitting groove 41A is provided with a second fitting groove 41B that extends along the second fitting portion 24B and fits into the second fitting portion 24B. The second fitting groove 41B is located in the center of the first fitting groove 41A in the width direction.

[0045] As shown in Figures 8(a) to 8(c), the widths of the first fitting groove 41A and the second fitting groove 41B are gradually increased as they approach both ends in the extending direction of the second fitting groove 41B. As shown in Figure 9, the inner circumferential surface 42 of the first attachment 40 is curved such that the outer surface is located further outward in the axial direction of the insertion hole 24 (up and down direction in Figure 9).

[0046] The first attachment 40 is made of an elastic material. In this embodiment, the first attachment 40 is made of the same material as the annular member 23. The outer circumferential surface 41 of the first attachment 40 is pressed against the inner circumferential surface 24a of the annular member 23.

[0047] The first attachment 60 has the same configuration as the first attachment 40. Therefore, a redundant explanation of the first attachment 60 will be omitted. <Second attachment 50, 70> As shown in Figures 1, 2, and 9, the second attachment 50 adjusts the size of the insertion hole 24 and is detachably attached to the inner circumferential surface 42 of the first attachment 40. In this embodiment, the second attachment 50 has a substantially arc shape in plan view.

[0048] As shown in Figure 9, the outer circumferential surface 51 and inner circumferential surface 52 of the second attachment 50 are curved such that the outer surface is located further outward in the axial direction of the insertion hole 24 (up and down direction in Figure 9).

[0049] The second attachment 50 is made of an elastic material. In this embodiment, the second attachment 50 is made of the same material as the annular member 23. The outer circumferential surface 51 of the second attachment 50 is pressed against the inner circumferential surface 42 of the first attachment 40.

[0050] The second attachment 70 has the same configuration as the second attachment 50. Therefore, a redundant explanation of the second attachment 70 will be omitted. <Operation of the First Embodiment> As shown in Figures 3 and 4, the size of the insertion hole 24 can be reduced by attaching the first attachment 40 to the inner circumferential surface 24a of the insertion hole 24. Furthermore, the first attachment 40 is not provided on the portion of the inner circumferential surface 24a of the insertion hole 24 that constitutes the adjacent portion 25. Therefore, while reducing the size of the insertion hole 24 by attaching the first attachment 40, it is possible to suppress an increase in the distance between the user's thumb and index or middle finger.

[0051] <Effects of the First Embodiment> (1) The first attachment 40 is provided on the inner circumferential surface 24a, excluding the portion that constitutes the adjacent portion 25.

[0052] With this configuration, the effects of the first embodiment described above are achieved, making it possible to improve usability while reusing the scissor body 11. (2) By elastically deforming the first attachment 40, the first attachment 40 can be easily attached to and detached from the inner circumferential surface 24a of the insertion hole 24 of the first handle portion 20.

[0053] (3) The first handle portion 20 includes a handle body 21 having a through hole 22 and an annular member 23 that is detachably attached to the inner circumferential surface 22a of the through hole 22 and has an insertion hole 24. Therefore, by making the material of the annular member 23 different from that of the handle body 21, it is possible to make the part that touches the user's fingers feel different from that of the handle body 21 when the scissors 10 is used without attaching the first attachment 40.

[0054] In particular, in this embodiment, the annular member 23 is formed from the same material as the first attachment 40. Therefore, the tactile feel of the part that touches the user's fingers can be made consistent whether the scissors 10 is used with the first attachment 40 attached or without the first attachment 40 attached. Thus, usability can be further improved.

[0055] (4) By attaching the second attachment 50 to the inner circumferential surface 42 of the first attachment 40, the size of the insertion hole 24 can be further reduced. This improves usability for users with smaller hands.

[0056] (5) Since the first attachment 40 is made of an elastic material, the first attachment 40 can be easily attached to and detached from the inner circumferential surface 24a of the insertion hole 24. On the other hand, when an external force is applied to the first attachment 40, the first attachment 40 undergoes elastic deformation, making it more likely to detach from the first handle portion 20.

[0057] In this respect, according to this embodiment, the first fitting portion 24A provided on the inner circumferential surface 24a of the insertion hole 24 and the first fitting groove 41A provided on the outer circumferential surface 41 of the first attachment 40 engage with each other, thereby preventing the first attachment 40 from falling off the first handle portion 20.

[0058] (6) In addition to the first fitting groove 41A and the first fitting portion 24A fitting together, the second fitting groove 41B and the second fitting portion 24B fitting together. This further prevents the first attachment 40 from falling off the first handle portion 20.

[0059] <Second Embodiment> The second embodiment will now be described with reference to Figures 10 and 11. This embodiment differs from the first embodiment in that the scissors do not have an annular member 23, and that the first attachment 40 and the second attachment 50 are replaced by an attachment 140. The following description will focus on the differences from the first embodiment.

[0060] As shown in Figure 10, the scissors are equipped with a first handle portion 20. The first handle portion 20 has a through hole 22 through which a finger can be inserted. The through hole 22 has a roughly semicircular shape in plan view. As shown in Figure 11, the attachment 140 is annular and has an insertion hole 143 through which the user's fingers can be inserted. The attachment 140 is detachably attached to the inner circumferential surface 22a of the through hole 22 of the first handle portion 20.

[0061] The attachment 140 has a semicircular shape in plan view and includes a straight section 144 that extends along the longitudinal direction of the scissors 10 (left-right direction in Figure 11) and semicircular arc sections 145 connected to both ends of the straight section 144. The thickness of the arc sections 145 is greater than the thickness of the straight section 144.

[0062] The center A of the through hole 143 is located closer to the adjacent portion 25 than the center B of the through hole 22. The attachment 140 is formed from an elastic material such as an elastomer.

[0063] The outer circumferential surface 141 of the attachment 140 is pressed against the inner circumferential surface 22a of the through hole 22. Since the second handle portion 30 has the same configuration as the first handle portion 20, its explanation will be omitted.

[0064] <Operation of the second embodiment> As shown in Figure 11, the size of the hole through which the fingers are inserted can be reduced by attaching the attachment 140 to the inner circumferential surface 22a of the through hole 22. Furthermore, the center A of the insertion hole 143 of the attachment 140 is located closer to the adjacent part 25 than the center B of the through hole 22. Therefore, by attaching the attachment 140, it is possible to reduce the size of the hole through which the fingers are inserted while suppressing an increase in the distance between the user's thumb and index or middle finger.

[0065] <Effects of the second embodiment> (7) The center A of the insertion hole 143 is located closer to the adjacent portion 25 than the center B of the through hole 22 into which the attachment 140 is installed.

[0066] With this configuration, the effects of the second embodiment described above are achieved, and the ease of use for the user can be pleasantly improved while reusing the scissor body 11. <Variation> This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0067] In the second embodiment, when the attachment 140 and insertion hole 143 exemplified are referred to as the first attachment 140 and first insertion hole 143, the scissors may also include a second attachment that is detachably configured to be attached to the inner circumferential surface of the first attachment 140. Although not shown in the figures, the second attachment is annular and has a second insertion hole through which the user's fingers can be inserted, and is detachably configured to be attached to the inner circumferential surface of the first insertion hole 143. The center of the second insertion hole should be located closer to the adjacent portion 25 than the center B of the through hole 22 into which the second attachment is mounted.

[0068] With this configuration, by attaching the second attachment to the inner circumferential surface of the first insertion hole 143, the size of the hole through which the fingers are inserted can be further reduced. Furthermore, the center of the insertion hole of the second attachment is located closer to the adjacent portion 25 than to the center B of the through hole 22. Therefore, while further reducing the size of the hole through which the fingers are inserted by attaching the second attachment, it is possible to suppress the increase in the distance between the user's thumb and index or middle finger.

[0069] In the second embodiment, the through-hole 22 is not limited to a semicircular shape in plan view, but can be appropriately changed to a circular shape including an oval or a polygonal shape including a rectangle. Furthermore, the attachment 140 can also be appropriately changed to match the shape of the through-hole 22.

[0070] The second fitting groove 41B can also be omitted from the outer circumferential surface 41 of the first attachment 40 in the first embodiment. In this case, the second fitting portion 24B can be omitted from the inner circumferential surface 24a of the insertion hole 24 of the annular member 23.

[0071] The first fitting groove 41A can also be omitted from the outer circumferential surface 41 of the first attachment 40. In this case, the first fitting portion 24A can be omitted from the inner circumferential surface 24a of the insertion hole 24 of the annular member 23.

[0072] In the first embodiment, the second attachment 50 can be omitted. The annular member 23 and the handle body 21 may be formed separately, and the annular member 23 may be attached to the handle body 21 so as to cover the inner circumferential surface of the handle body 21.

[0073] The annular member 23 may be made of a different material than the first attachment 40. In this case, for example, the annular member 23 may be made of a harder material than the first attachment 40.

[0074] The annular member 23 can be omitted in the first handle portion 20. That is, the first handle portion 20 may consist only of the handle body 21. In this case, the through hole 22 exemplified in the first embodiment functions as a through hole through which a finger can be inserted.

[0075] The attachment material is not limited to elastic materials, but may also be made of a rigid resin material. The attachment may be provided on only one of the first handle portion 20 and the second handle portion 30.

[0076] In the first embodiment, the insertion hole 24 is not limited to a semicircular shape in plan view, but can be changed as appropriate to a circular shape including an oval or a polygonal shape including a rectangle.
