Abstract

PROBLEM TO BE SOLVED: To provide scissors with a simple structure in which a punching operation by a pointed end part can be safely performed by closing its entire body and the pointed end can be not exposed when the pointed end is not used. SOLUTION: A passage part is formed by forming guide surfaces parallel to both surfaces in the substantially central part of a pivot 13. The connecting hole 15 of a half body 10B pivotally supported by the pivot 13 comprises first and second round holes 15b spaced by a prescribed distance and having the same diameter as that of the pivot 13 and a slot for connecting the first and second round holes 15b together. Thus, the position of a supporting point is changed by the pivot 13 of the half body 10B having a pointed end part 16. Accordingly, the pointed end part 16 can be located at the same position as that of the end of the edge part 11a of the other half body 10A or can protrude more than this end.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to scissors, and more particularly to scissors that are used when children or students work or that housewives use in the kitchen.

[0002]

2. Description of the Related Art "Scissors" are not limited to those for work or kitchen use, and various kinds of scissors have already been proposed and used. In particular, not only the function of "cutting" but also various functions to which a specific function is added have been proposed. As one of them, there has been proposed one in which the tip of a blade portion is sharpened so as to perform drilling at the "pointed portion".

[0003] "Scissors" having such "points"
When closed, the "tip" overlaps the blade of the other half-body (half of the scissors, which integrates the blade with the glasses to insert the fingers), ensuring safety when not in use It is something to do. In order to make a hole with the "point", the pair of halves are opened to expose the entire "point", and in this state, work is carried out with scissors.

However, opening a pair of halves means that the blades of each halves are exposed, and these blades hit the palm, sometimes causing pain, and the feeling of use is extremely poor. . In particular, in school work using empty cans, it is necessary to make holes in the body of the can, etc.At that time, it is necessary to put a lot of power into the entire open scissors, so you will feel great pain In some cases, the work itself may not be possible.

[0005] For this reason, it has been considered that a cap may be put on a portion other than the "pointed end portion", particularly on the blade portion, so as to relieve pain at the time of working. Eventually, it will be in the same state as without the cap.

[0006] The same can be in the kitchen. In other words, when trying to pierce various packs, especially in the case of elderly people with weak power, you will not be able to apply power without holding the entire open scissors with your hands, so you will feel pain due to the blade part and work It happens that you cannot do it.

[0007] The inventors of the present invention have studied how to make use of the advantages of the "sharp end" which can be perforated, without causing the above-mentioned pain and safe use. As a result of various studies, the present invention has been completed.

[0008]

SUMMARY OF THE INVENTION The present invention has been made on the basis of the above circumstances, and the problem to be solved is to provide a "pointed end" for making a hole at the tip of the blade. However, it is to provide scissors that are safe and easy to use.

That is, first, the object of the invention according to claim 1 is that the drilling operation by the “pointed end” can be performed with the whole closed, and the operation can be performed safely. The purpose of the present invention is to provide a scissor having a simple structure that allows the "point" to be left unexposed when the point is not used.

Another object of the present invention is to provide a scissor which is useful for processing a vinyl-coated electric wire, in addition to achieving the same object as in the above-mentioned claim 1. is there.

[0011]

Means for Solving the Problems In order to solve the above problems, first, means according to the first aspect of the present invention will be described with reference numerals used in the following description of embodiments. "The blades 11a and 11b and the glasses 12a and 1
A pair of half bodies 10A and 10B, each of which is integrated with the other half body 10B, which is openably and closably connected by a single pivot 13; By forming guide surfaces 14a and 14b that are parallel to each other on substantially both sides of the central portion of the passage 13, a passage portion 14 is formed. Being Axis 1
The first and second round holes 15a and 15b having the same diameter as 3 and a long hole 15c for connecting the first and second round holes 15a and 15b are formed. By changing the position of the fulcrum by the pivot 13, the pointed end 16 is made to be the same position as the tip of the blade 11a of the other half body 10A, or can be projected from this tip. "Scissors 10".

b, and the contact between the two is made by the first round hole 15a and the second round hole 15a.
Since the operation is always performed within the distance between the round holes 15b, a stable closed state can be always created.

Therefore, according to the scissors 10 of the first aspect, the drilling operation by the "pointed end portion 16" can be performed with the whole closed, and the operation can be performed safely.
When not using the “tip 16”, the “tip 1”
6 "can be left unexposed.

In order to solve the above-mentioned problem, a means adopted by the invention according to claim 2 is that the scissors 10 according to claim 1 are described as “the root portion of the pointed end portion 16 and the other half body. The concave portion 1 is formed in a portion facing the blade portion 11a of 10A.
7 ".

That is, the scissors 10 according to claim 2 of the present invention.
In this case, the concave portion 17 is formed at the root of the pointed end portion 16, which is convenient when it is desired to peel off the vinyl coating of the electric wire used for the work.

That is, a vinyl-coated electric wire is inserted into the recess 17 and “cut” using the scissors 10.
With the work done, the vinyl sheath can be cut or cut without cutting the conductor inside.

In the following embodiment, as shown in FIG. 2, when the tip 16 is projected,
