Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a scissors, in particular, a scissors that can be held without dropping a piece to be cut when the work is cut.
[0002]
[Prior art]
In general, as shown in FIG. 9, the Western bowl 10 is pivotally supported by a support shaft 13 in a state where two blade bodies 11 and 12 cross each other, and the support shaft 13 serves as a fulcrum S. X-shaped structure. The rubbing state between the blade edges 11 a and 12 a of the blade bodies 11 and 12 is maintained by the support shaft 13.
[0003]
In such a scissors 10, it is difficult to reduce the thickness due to the need for the support shaft 13, and three points including two blade bodies 11 and 12 and the support shaft 13 as components constituting the scissors 10 are included. Is required as compared with the Japanese style iron without the support shaft 13, and there is a problem in that it takes time to assemble the collar 10. Corresponding to such a problem, a saddle having no support shaft has been proposed (for example, see Japanese Patent Publication No. 1-48782).
[0004]
First, the scissors without the above-described support shaft will be described with reference to FIGS.
[0005]
FIG. 4 shows a scissor 1 that does not have a support shaft. This scissor 1 is made up of a first blade body 2 and a second blade body 3 made of thin plate materials that are stacked so as to intersect the X-shape. The blade edges 21 and 31 facing each other are formed on the side edges of the front half portions of the blade bodies 2 and 3, and the handles 22 and 32 having the holes 22a and 32a through which the fingertips can pass are formed in the latter half portion. ing.
[0006]
Tongue pieces 24 and 34 partitioned from the periphery by C-shaped slits 23a and 33a are formed at the centers of the intersecting portions 23 and 33 of these blades 2 and 3 that are overlapped with each other. (See FIG. 5). These tongue pieces 24 and 34 are displaced in the direction of the mating blades 2 and 3 to be overlaid. That is, as shown in FIG. 8A, the tongue piece 24 formed on the first blade body 2 is in the direction of the second blade body 3, and the tongue piece 34 formed on the second blade body 3 is the first piece. Each blade 2 is displaced in the direction of the blade 2 by an amount e that is equal to or very close to the thickness t within a range not exceeding the thickness t of each blade 2, 3.
[0007]
Further, the portions 23b and 33b in which the respective tongue pieces 24 and 34 are continuous with the surroundings are in positions opposite to each other with respect to the tongue pieces 24 and 34, respectively. For example, as clearly shown in FIG. 5, the portion 23 b where the tongue piece 24 of the first blade body 2 continues is located closer to the blade edge 21, and the portion 33 b where the tongue piece 34 of the second blade body 3 continues. Is located closer to the handle 32.
[0008]
Of these tongue pieces 24, 34, a raised portion 24 a is formed at the center of one tongue piece 24, and a small hole 34 a is formed at the center of the other tongue piece 34. The raised portion 24a formed on the one tongue piece 24 protrudes in a direction not exceeding the displacement amount e in the direction opposite to the above-described displacement direction of the tongue piece 24.
[0009]
When the scissors 1 are assembled with the blade bodies 2 and 3 configured in this way, the tongue pieces 24 and 34 that protrude by the displacement amount e are overlapped with each other and the blade pieces 2 and 3 face each other and overlap each other. (See FIG. 8B). Next, the tongues 24 and 34 are forced to be elastically deformed so as to temporarily increase the amount of displacement e, and the tips of the tongues 24 and 34 are made to be slits 23a and 33a of the counterpart blade body. Then, as shown in FIG. 8 (c), the blades 2 and 3 are shifted in the directions of the arrows opposite to each other, and the tips of the tongue pieces 24 and 34 are inserted into the opposite back sides of the tips. Subsequently, when the blades 2 and 3 are further shifted in the direction of the arrow, the raised portion 24a of the tongue piece 24 and the small hole 34a of the tongue piece 34 eventually coincide with each other, and each elastic deformation has been caused until then. The tongue pieces 24 and 34 are restored, and the raised portions 24a are fitted into the small holes 34a.
[0010]
[Problems to be solved by the invention]
By the way, when a cut object such as paper is cut by the aforementioned scissors, the cut object is divided into two parts. As a result, one of the divided pieces can be grasped by the remaining hand. The cut piece falls on the desk or the like. This tendency is particularly remarkable when the piece to be cut is a small piece such as a corner of paper or the like. Accordingly, there is a possibility that the fallen cut piece may be mixed with other materials on the desk, and the cut piece needs to be selected and picked up from other materials, resulting in troublesome work.
[0011]
It is to be noted that a long body is provided in which a holding body is provided so as to face the outer surface of one blade body and the inner surface of the other blade body, and when a cut object such as a branch is cut, the piece to be cut is held by the opposite holding body Japanese cypress is known (see, for example, Japanese Utility Model Publication No. 62-22126).
[0012]
However, when the object to be cut is cut with such a scissors, the piece to be cut is held by the opposing holding members only after the cutting of the object to be cut is completed. Therefore, when cutting an object having a thickness equal to or less than the polymerization distance of the blade edge of the blade body, for example, paper or the like, immediately after the cutting, the sandwiching bodies are facing each other at a slight distance without contacting each other, There was a drawback that the piece to be cut could not be securely clamped.
[0013]
The present invention has been made in view of such problems, and provides a ridge that can securely hold a piece to be cut even when the piece to be cut is thin paper or the like.
[0014]
[Means for Solving the Problems]
In the present invention, the first blade body and the second blade body each having a blade edge on the side edge of the first half portion and a handle on the second half portion are overlapped so as to face each other at the blade edge and intersect in an X shape, In the scissors that form a fulcrum at the intersection, the substantially central portion of the clamping member is pivotally supported on the inner surface of the front half of one blade body, and the clamping member faces the cutting edge of the other blade body. An object to be cut by a pair of blades has a protrusion that can be brought into contact with the vicinity of the rear edge of the edge of the other blade immediately before the cutting of the object to be cut by the pair of blades near the rear edge of the side edge . At the time of cutting, the protruding part of the clamping member is brought into contact with the vicinity of the rear edge of the blade edge of the other blade body, and the clamping member is forced in the direction in which the front edge of the side edge contacts the blade edge front edge of the other blade body. It is made to rotate, and a to-be-cut piece is clamped between the side edge front end part of a clamping member, and the blade edge front end part of the other blade body. It is intended.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0016]
It should be noted that the same reference numerals are used for the same elements as the elements constituting the kite 1 shown in FIGS. 4 to 8, and the detailed description thereof is omitted to avoid duplication.
[0017]
FIG. 1 shows a scissors 1A according to the present invention, and a clamping member 4 is pivotally supported at the substantially central portion thereof on the inner surface of a first blade body 2 constituting the scissors 1A. And the clamping member 4 is provided so that the side edge 41 which faces the blade edge 31 of the 2nd blade body 3 may keep a fixed distance from the blade edge 21 of the 1st blade body 2, and when the blade edges 21 and 31 are closed, The blade edge 31 of the two blade body 3 is superposed on the blade edge 21 of the first blade body 2, and contacts the vicinity of the front end portion of the side edge 41 of the clamping member 4 at that time, as will be described later.
[0018]
Further, in the vicinity of the rear end portion of the side edge 41 of the sandwiching member 4, a protruding portion 41a slightly exceeding the extension line 41j of the side edge 41 is formed, and this protruding portion 41a has a pair of blade bodies 2, 3 is in contact with the vicinity of the rear end portion of the blade edge 31 of the second blade body 3 immediately before the completion of the cutting of the workpiece P such as paper, and the front edge portion of the side edge 41 of the clamping member 4 is the blade edge of the second blade body 3. It is rotated in a direction in contact with the front end portion of 31. Then, when the cutting by the cutting edges 21 and 31 is completed, they are superposed, and at this time, the vicinity of the rear end portion of the cutting edge 31 is in contact with the protruding portion 41a of the holding member 4 and the side edge 41 of the holding member 41 The front end portion is set so as to contact the front end portion of the blade edge 31.
[0019]
Furthermore, the side edge 41 of the clamping member 41 is formed with a concave portion 41b having a certain length from the protruding portion 41a toward the front.
[0020]
Therefore, when cutting the workpiece P such as paper using such a ridge 1A, the protruding portion 41a of the clamping member 41 comes into contact with the rear end portion of the blade edge 31 of the second blade body 3 immediately before the completion of cutting. When the cutting edges 21 and 31 are still closed and the cutting operation is continued, the clamping member 4 is pressed by the cutting edge 31 of the second blade body 3 as shown in FIG. Then, the front edge portion of the side edge 41 is forcibly rotated in the direction approaching the front end portion of the blade edge 31 of the second blade body 3 (the arrow direction in FIG. 2A).
[0021]
As a result, when the cutting of the workpiece P is completed, the front end portion of the side edge 41 of the clamping member 4 and the front end portion of the cutting edge 31 of the second blade body 3 come into contact with each other, and the cut piece P1 (see FIG. 2 (b)) can be securely held without dropping.
[0022]
In this case, when the workpiece P is cut on the rear end side of the cutting edges 21 and 31, the workpiece P is not cut off, and it is not necessary to sandwich the cutting piece in this state. Therefore, the recessed part 41b formed in the rear end part of the side edge 41 of the clamping member 4 indicates that the workpiece P is not clamped at the start of cutting. Further, when the workpiece P is a small piece such as a corner of paper or the like, if it is cut at the latter half of the cutting edges 21 and 31 of the blades 2 and 3, the workpiece P is cut between the tip of the clamping member 4. Since it cut | disconnects without pinching the piece P1, the recessed part 41b is calling attention so that it may not cut | disconnect by the latter half part of the blade edge | tips 21 and 31 which are the vicinity.
[0023]
In addition, since the to-be-cut | disconnected piece P1 can be clamped if the front-end part of the side edge 41 of the clamping member 4 and the front-end part of the blade edge | tip 31 of the blade body 3 contact | abut, the blade edge | tip 31 of the blade body 3 has a fixed blade edge angle. Further, the side edge 41 of the clamping member 4 may also be an inclined surface other than the plane orthogonal to the inner surface of the first blade body 2, and the shape of the blade edge 31 and the tip of the clamping member 4 The surface shape is not limited.
[0024]
Further, in the above-described embodiment, the pinching member 4 is provided on the rod 1 that does not have a support shaft. However, the pinching member 4 may be provided on the general rice bran shown in FIG.
[0025]
【The invention's effect】
As described above, according to the present invention, even when a thin object such as paper is cut, the front edge of the side edge of the clamping member and the other blade that are forcibly rotated when cutting is completed. The piece to be cut can be securely sandwiched between the front end portion of the cutting edge of the body without dropping.
