Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the structure of the handle of a so-called western scissor in which a pair of scissors are crossed and supported in an X shape.

[Prior Art] Conventionally, as scissors of this type, there are those shown in FIGS. 8 to 10, for example. In this scissors, a pair of scissors pieces 1 and 2 made of metal are rotatably supported by an opening / closing center shaft portion 3, and a tip end side of the opening / closing center shaft portion 3 is a blade portion 4 and a coaxial portion. The pedestals 5 and 6 are located closer to the base end side than 3. In the handle shafts 5 and 6, the support plate portions 7 and 8 extending continuously from the opening / closing center shaft portion 3 to the blade portions 4 have finger rings 9,1.
0 is provided. The two finger hooking rings 9 and 10 are juxtaposed along a plane P including the opening and closing direction A of the two scissoring pieces 1 and 2, and when the both scissoring pieces 1 and 2 are closed, The side surfaces 9a, 10a are in contact with each other.

In order to bring the finger hook rings 9 and 10 into contact with each other in this manner, the support plates 7 and 8 are provided with bent portions 11 and 16, respectively.

[Problems to be solved by the invention] In the case of the handle portions 5 and 6 having the bent portions 11 and 16 on the support plate portions 7 and 8 as described above, bend the support plate portions 7 and 8 respectively. The work was necessary and the work was very troublesome.

By the way, depending on the size and shape of both finger hook rings 9 and 10, it may be necessary to widen the width of both support plate portions 7 and 8, but if the width is widened, it is difficult to bend the support plate portions 7 and 8. There was a problem.

Further, there is a problem that the sharpness is not ideal in a state immediately before the tips of the blade edges of the blade portions are overlapped by closing both scissors pieces.

Therefore, the present invention is the one in which the sharpness is improved to a state just before the tip of the cutting edge is superposed by devising the structure and shape of both supporting portions.

Configuration of the Invention [Means for Solving the Problems] In view of this object, the present invention rotatably supports a pair of scissor pieces by an opening / closing center shaft portion, and the tip side of the opening / closing center shaft portion is a blade portion. In addition, the base end side of the opening / closing center shaft is a handle, and the handle plate provided on both handle shafts extending from the opening / closing center shaft is provided with a finger ring, and when both scissor pieces are closed, In the scissors in which the inner side surfaces of the scissor pieces can be brought into contact with each other, only one of the support plate portions is bent in a direction orthogonal to a plane including the opening / closing direction of the scissor pieces. A portion is provided, and both finger hook rings are arranged side by side along a plane including the opening / closing direction of both scissor pieces, and the bending portion and the other of the other portions facing the bending portion are within the rotation operation range of both scissor pieces. The gist is that the scissor pieces are brought into contact with each other at their contact points, and the blade portions of both scissor pieces can be pressed against each other by this contact.

[Operation] In the present invention, one of the support plate portions 7 and 8 of the handle portions 5 and 6 is attached to one support plate portion 8 in a direction orthogonal to the plane P including the opening / closing direction A of the scissor pieces 1 and 2. By providing the bent portion 11 that is bent, the contact point portions 14 and 15 of both the support plate portions 7 and 8 come into contact with each other, and the force causes the both blade portions to be further pressed against each other. There is. Therefore, the sharpness is improved.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIGS. 1 to 3, a pair of scissor pieces 1 and 2 formed of a metal plate are rotatably supported by an opening / closing center shaft portion 3, and the tip end side of the opening / closing center shaft portion 3 is a blade portion. 4, and the handle portions 5 and 6 are located on the base end side of the coaxial portion 3. Support plate parts 7 and 8 are continuously extended from the opening / closing center shaft part 3 to the blade part 4 on the handle parts 5 and 6, respectively.
Finger rings 9 and 10 are provided at the ends of 7 and 8.

The support plate portion 8 of the handle portion 6 of one scissor piece 2 is provided with a bent portion 11 which is bent in a direction orthogonal to a plane P including the opening / closing direction A of both scissor pieces 1 and 2, and the other The support plate portion 7 of the handle portion 5 of the scissors piece 1 extends parallel to the same plane P. Therefore, both finger hook rings 9 and 10 are arranged side by side along the same plane P, and both scissor pieces
When 1 and 2 are closed, the inner side surfaces 9a and 10a of both finger hook rings 9 and 10 can come into contact with each other.

The sizes and shapes of the finger hook rings 9 and 10 are different from each other, so that the width of the support plate portion 7 of the one handle 5 is wider than the width of the support plate 8 of the other handle 6 accordingly. ing.

Now, as shown in FIG. 4, when both scissors pieces 1 and 2 are opened to some extent, as shown in FIG.
Side faces 12 and 1 of both support plate parts 7 and 8 facing each other at both handle parts 5 and 6 in the vicinity.
3, the support plates 7 and 8 are pushed apart in the direction of the arrow in FIG. 5 by contacting each other, and the force causes the blades 4 to be pressed against each other.

As shown in FIG. 6, in a state immediately before the scissors pieces 1 and 2 are closed to each other and the tips of the cutting edges 4a of the blade portions 4 are overlapped with each other, as shown in FIG. At the bent portion 11 where the portions 7 and 8 intersect with each other, the contact point portions 14 and 15 of the support plate portions 7 and 8 contact each other and the contact point portions 14 and 15 are spread in the arrow direction of FIG. The two blade portions 4 are pressed against each other by the force. Therefore, the sharpness is improved.

In particular, in this embodiment, since the bent portion 11 is provided only on one support plate portion 8 of the support plate portions 7 and 8 of the both handle portions 5 and 6, a comparison with the case of the conventional art is made. Then, only one supporting plate portion 8 needs to be bent, and the labor of bending work can be saved.

EFFECTS OF THE INVENTION According to the present invention, it is possible to save the labor of bending work of one handle portion and to perform only the bending work of the other handle portion, which facilitates the bending work.

Further, according to the present invention, the other scissor piece facing the bent portion is brought into contact at the contact point portion, and the blade portions of both scissor pieces can be brought into pressure contact with each other by this contact, so that when the opening / closing operation is performed. In the above, since the two blade portions are pressed against each other, sharpness can be improved.
