Rotate. Since the head 31 of the rotating portion 30 has the same shape as the rectangular portion 18a of the first shaft hole 18 and is formed to be slightly smaller, the rectangular portion 18a of the first shaft hole 18 is formed by the rotating portion 30. The first scissors piece 10 is separated from the second scissors piece 20.

Subsequently, as shown in FIG. 4B, the first scissors piece 10 is turned over, and the rectangular portion 18a of the first shaft hole 18 of the first scissors piece 10 is attached to the second scissors piece 20. Align with the position of the head 31 of 30. In this state, the head 31 of the rotating portion 30 is inserted into the rectangular portion 18a of the first shaft hole 18 of the first scissors piece 10, and the first shaft hole 18 of the first scissors piece 10 is inserted into the rotating portion 30. Align with the position of the first shaft portion 32 of. Since the circular portion 18b of the first shaft hole 18 of the first scissors piece 10 has the same shape as the first shaft portion 32 of the rotating portion 30 and is formed to have a slightly larger diameter, the first scissors piece 10 is the first. 2 Rotates with respect to the scissors piece 20.

As shown in FIG. 4B, due to the rotation of the first scissors piece 10 with respect to the second scissors piece 20, the first grip portion 11 and the second grip portion 21 overlap in the axial direction of the rotating portion 30, and the first It is assumed that the first surface 10a of the scissors piece 10 and the first surface 20a of the second scissors piece 20 face each other. In this state, as shown in FIG. 4C, the first surface 14a of the first tip-side flat portion 14 is in contact with the first surface 24a of the second tip-side flat portion 24, and the first grip portion The first surface 11a of 11 is in contact with the first surface 21a of the second grip portion 21. Further, the first cutting portion 17 of the first scissors piece 10 and the second cutting portion 27 of the second scissors piece 20 face in the same direction. Then, the convex portion 41 as an engaging portion protruding from the first surface 11a of the first grip portion 11 which is a flat surface is recessed in the first surface 21a of the second grip portion 21 which is a flat surface. It is housed in the recess 42 as the engaged portion.

As a result, in the first scissors piece 10 and the second scissors piece 20, the first grip portion 11 and the second grip portion 21 are overlapped in the axial direction of the rotating portion 30, and the first scissors piece 10 is the first. The first surface 10a and the first surface 20a of the second scissors piece 20 are connected so as to face each other.

At this time, the first shaft portion 32 having a circular cross section of the rotating portion 30 is located in the circular portion 18b having a circular cross section in the first shaft hole 18. Further, the head portion 31 having a substantially rectangular cross section of the rotating portion 30 is located so as to intersect the rectangular portion 18a having a substantially rectangular cross section of the first shaft hole 18, as shown in FIG. 4 (b). As shown, the first scissors piece 10 is connected to the second scissors piece 20 in a retaining state in the second recess 19b on the second surface 10b side.

As a result, the first scissors piece 10 and the second scissors piece 20 are connected by the rotating portion 30, and the first grip portion 11 and the second grip portion 21 are stored so as to overlap in the axial direction of the rotating portion 30. It is considered to be a form. In this storage mode, the rotation of the first scissors piece 10 and the second scissors piece 20 around the rotating portion 30 is restricted by the engagement of the convex portion 41 and the concave portion 42 as the engaging structure.

According to the scissors of the present embodiment, the following effects can be obtained.
(1) In the above embodiment, the second scissors piece 20 is rotated with respect to the first scissors piece 10, and the longitudinal direction of the rectangular portion 18a of the first shaft hole 18 formed in the first scissors piece 10 is set. When it matches the longitudinal direction of the head 31 of the rotating portion 30 attached to the second scissors piece 20, the first scissors piece 10 and the second scissors piece 20 are separated. Subsequently, the first scissors piece 10 is turned over with respect to the second scissors piece 20, and the rectangular portion 18a of the first shaft hole 18 of the first scissors piece 10 is fitted into the rotating portion 30 attached to the second scissors piece 20. The first scissors piece 10 is rotated. At this time, if the longitudinal direction of the rectangular portion 18a of the first shaft hole 18 and the longitudinal direction of the head 31 of the rotating portion 30 intersect, the head 31 is the second recess 19b of the first scissors piece 10. It is housed inside, and the first scissors piece 10 and the second scissors piece 20 are connected in a retaining state.

The scissors in the stored form are in a state in which the first grip portion 11 and the second grip portion 21 are overlapped in the axial direction of the rotating portion 30. Therefore, the width dimension of the scissors is substantially the same as the width dimension of the first scissors piece 10 or the second scissors piece 20. The width of the scissors is smaller than that of the scissors used, and the entire scissors can be made compact. Scissors with excellent storability can be obtained.

(2) In the scissors in the storage form, the convex portion 41 projecting from the first surface 11a of the first grip portion 11 engages with the concave portion 42 formed on the first surface 21a of the second grip portion 21. Therefore, the relative rotation of the first scissors piece 10 and the second scissors piece 20 around the rotating portion 30 is regulated. Therefore, in the stored state, the first blade portion 13 and the second blade portion 23 overlap, and the state in which the first grip portion 11 and the second grip portion 21 overlap is maintained, and the first cutting portion 17 and the second cutting portion 17 and the second cutting portion are maintained. It is suppressed that 27 is inadvertently exposed. Along with obtaining scissors with excellent storability, safety in the storage form is improved, and convenience of carrying is improved.

(3) In the scissors of the above embodiment, the engaging structure that regulates the rotation of the first scissors piece 10 and the second scissors piece 20 is a convex portion 41 and a second grip portion that are projected from the first grip portion 11. It is composed of a recess 42 recessed in 21. With a simple structure such as a convex portion 41 and a concave portion 42, the relative rotation of the first scissors piece 10 and the second scissors piece 20 can be regulated.

(4) The first surface 11a of the first grip portion 11 is formed as a flat surface except for the convex portion 41, and the first surface 21a of the second grip portion 21 is a flat surface except for the concave portion 42. Is formed as. Further, in the storage form, the first surface 11a of the first grip portion 11 and the first surface 21a of the second grip portion 21 are in contact with each other, and the first surface 14a of the first tip end side flat portion 14 of the first blade portion 13 is brought into contact with each other. The first surface 24a of the second tip-side flat portion 24 of the second blade portion 23 is in contact with the first surface 24a. Therefore, in the stored state, a gap is unlikely to be formed between the first scissors piece 10 and the second scissors piece 20, and the shape can be made compact. Further, the rattling of the first scissors piece 10 and the second scissors piece 20 is suppressed, and the storage form can be stabilized.

(5) The first grip portion 11 has a thickness of about 5 to 10 mm, and the second grip portion 21 also has a thickness of about 5 to 10 mm. Therefore, the first grip portion 11 and the second grip portion 21 gripped by the user have an appropriate thickness, and are comfortable to use.

(6) The first blade portion 13 has a shape in which a first tip end side flat portion 14 on the tip end side and a first base end side flat portion 15 on the base end side are continuously provided via a first inclined portion 16. It is fixed in a state of being inserted into the intermediate portion in the thickness direction of the first grip portion 11. Further, the second blade portion 23 has a shape in which the second tip end side flat portion 24 on the tip end side and the second base end side flat portion 25 on the base end side are continuously provided via the second inclined portion 26. The blade is fixed in a state of being inserted into the intermediate portion in the thickness direction of the second grip portion 21. Therefore, even when the scissors are stored, the thickness of the first grip portion 11 and the second grip portion 21 in an overlapping state is absorbed by the first inclined portion 16 and the second inclined portion 26, and the second. 1 The first surface 24a of the tip-side flat portion 14 and the second tip-side flat portion 24 can be brought into contact with each other.

(7) The rotating portion 30 has a head portion 31 having a substantially rectangular cross section and a first shaft portion 32 having a circular cross section connected to the head portion 31, and is attached to the second scissors piece 20 in advance. The first shaft hole 18 formed in the first scissors piece 10 is formed in a shape in which a rectangular portion 18a having the same shape as the head 31 and a circular portion 18b having the same shape as the first shaft portion 32 overlap. Therefore, by rotating the first scissors piece 10 with respect to the second scissors piece 20, the first scissors piece 10 and the second scissors piece 20 can be easily separated and easily connected. can. The work of using the scissors as a usage form or a storage form can be easily performed.

(8) Since the first scissors piece 10 and the second scissors piece 20 are separable, when sharpening the first cutting portion 17 of the first scissors piece 10 or the second cutting portion 27 of the second scissors piece 20, etc. Easy to work with. Further, when dirt adheres to the periphery of the first shaft hole 18 and the second shaft hole 28, that is, the portion where the first scissors piece 10 and the second scissors piece 20 overlap, the dirt can be easily removed.

The above embodiment can be changed as follows. The above embodiment and the following modified examples can be applied in combination with each other within a technically consistent range.
The engaging structure that regulates the movement of the first scissors piece 10 and the second scissors piece 20 in the storage form is recessed in the convex portion 41 and the second grip portion 21 protruding from the first surface of the first grip portion 11. It is not limited to the configuration of the recess 42. As long as the first scissors piece 10 and the second scissors piece 20 do not rotate relative to each other around the rotating portion 30, the engaging structure thereof is not particularly limited. For example, as shown in FIGS. 5A and 5B, a recess 52 recessed inward is formed on the peripheral edge of the second finger hook hole 22 on the first surface 21a side of the second grip portion 21. A bent portion 51 bent so as to be inclined toward the first surface 11a may be formed at the base end portion of the first grip portion 11. Even with such scissors, as shown in FIG. 6, if the first scissors piece 10 is turned over so that the first surface 10a of the first scissors piece 10 and the first surface 20a of the second scissors piece 20 face each other. good. At this time, assuming that the first grip portion 11 and the second grip portion 21 overlap each other in the axial direction of the rotating portion 30, the first grip is made in the recess 52 formed in the peripheral portion of the second finger hook hole 22. The bent portion 51 formed in the portion 11 is accommodated so as to be fitted. As a result, the relative rotation of the first scissors piece 10 and the second scissors piece 20 is restricted in the stored state of the scissors.

The engaging structure may have a shape as shown in FIGS. 7 (a) and 7 (b). As shown in FIG. 7A, the side edge of the first blade portion 13 of the first scissors piece 10 facing the first cutting portion 17 is orthogonal to the first surface 13a of the first blade portion 13. A locking portion 60 extending toward the second surface 13b is formed in the shape. The locking portion 60 extends from the tips of the first locking portion 61 and the first locking portion 61 orthogonal to the first surface 13a of the first blade portion 13 to the second surface 13b of the first blade portion 13. The two locking portions 62 are formed in an L-shaped cross section. The distance between the second surface 13b of the first blade portion 13 and the upper surface of the second locking portion 62 is formed to be slightly larger than the thickness of the second blade portion 23.

Even with such scissors, as shown in FIG. 7B, the tightening at the rotating portion 30 is removed, the second scissors piece 20 is turned over, and the second surface 10b and the second scissors of the first scissors piece 10 are turned over. The second surface 20b of the piece 20 may face each other. At this time, assuming that the first grip portion 11 and the second grip portion 21 overlap each other in the axial direction of the rotating portion 30, the second blade portion 23 is placed between the second locking portion 62 and the first blade portion 13. The side edge of the second blade portion 23 comes into contact with the first locking portion 61, and the relative rotation of the first scissors piece 10 and the second scissors piece 20 is restricted.

As another example of the engaging structure, for example, a band piece is attached to at least one of the first scissors piece 10 and the second scissors piece 20, and the first grip portion 11 and the second grip portion 21 are attached. In the storage form in which the rotating portion 30 is stacked in the axial direction, a band piece may be wound around the first scissors piece 10 and the second scissors piece 20. By doing so, the movement of the first scissors piece 10 and the second scissors piece 20 is restricted.

-The formation position of the engaging structure is not particularly limited. The convex portion 41 of the above embodiment is formed on the tip end side of the first finger hook hole 12 of the first grip portion 11, and the concave portion 42 is formed on the tip end side of the second finger hook hole 22 of the second grip portion 21. However, the formation positions of the convex portion 41 and the concave portion 42 are not limited to this. It may be the base end side of the first grip portion 11 and the base end side of the second grip portion 21, and is an intermediate portion between the tip end side and the base end side of the first blade portion 13 and the second blade portion 23. You may. Similarly, the bent portion 51 shown in FIGS. 5 (a) and 5 (b) may be formed at a position other than the base end portion of the first grip portion 11. In this case, the recess 42 may be formed at a predetermined position of the second scissors piece 20 facing the bent portion 51 in the stored state. Further, the locking portion 60 shown in FIGS. 7 (a) and 7 (b) may be provided on the second scissors piece 20 instead of the first scissors piece 10. Even if the locking portion 60 is provided not on the first blade portion 13 of the first scissors piece 10, but on the first grip portion 11 of the first scissors piece 10 or the second grip portion 21 of the second scissors piece 20. good. As long as the movement of the first scissors piece 10 and the second scissors piece 20 that can be placed in the stored state can be restricted, the forming position of the engaging structure is not particularly limited.

In this case, the nut 36 may be removed, the bolt 35 may be removed from the first shaft hole 18 and the second shaft hole 28, the first scissors piece 10 may be turned over, and the bolt 35 and the nut 36 may be connected again.

When the bolt 35 and the nut 36 are connected, the first scissors piece 10 and the second scissors piece 20 may not be connected by the bolt 35 and the nut 36 in the storage form. Even when the first scissors piece 10 and the second scissors piece 20 are not connected by the rotating portion 30 (bolt 35 and nut 36), for example, by winding the band piece, the first scissors piece 10 and the first scissors piece 20 and the first scissors piece 20 2 The movement of the scissors piece 20 is restricted. Alternatively, the movement of the first scissors piece 10 and the second scissors piece 20 may be restricted by forming the locking portions 60 as shown in FIG. 7 at a plurality of locations. In this case, the storage form in which the first grip portion 11 and the second grip portion 21 are overlapped with each other in the axial direction of the rotating portion 30 (bolt 35 and nut 36) is the first grip portion 11 and the second grip portion 11. It is assumed that the portion 21 overlaps in the opening direction of the first shaft hole 18 and the second shaft hole 28 into which the rotating portion 30 is inserted.

The engaging structure is not limited to the one that regulates rotation, and the first grip portion 11 and the second grip portion 21 are maintained in a state of being overlapped in the axial direction of the rotating portion 30, and the first scissors piece 10 to the first scissors piece 10 to the first. 2 Anything that regulates the movement of the scissors piece 20 may be sufficient. The shape of the engaging structure is not particularly limited as long as the first scissors piece 10 and the second scissors piece 20 do not move relative to each other in the stored state.

If the first grip portion 11 and the second grip portion 21 are overlapped with each other in the axial direction of the rotating portion 30, the first surface 10a and the second scissors piece 20 of the first scissors piece 10 may be stored. The first surface 20a is not opposed to each other, and the second surface 13b of the first blade portion 13 and the first surface 23a of the second blade portion 23 may be opposed to each other as in the usage pattern.

-In the above embodiment, the first shaft hole 18 has a shape in which the rectangular portion 18a and the circular portion 18b at the intermediate portion in the longitudinal direction of the rectangular portion 18a overlap. However, the shape of the first shaft hole 18 is not limited to this.
