Abstract

The present invention relates to a scissor with a new structure that can be prevented from accidentally injuring the blade of the scissors or damage of the blade of the scissors.

According to the present invention, the handle 2 is provided at one side thereof and the pair of blade members 6 and 7 having the blades 4 formed at the other side thereof are rotatably coupled to the hinge shaft 8 to allow the user to rotate the hinge shaft 8. By holding the handle 2 and rotating the blade members 6 and 7 in the direction of opening or folding, the blade members 6 and 7 can be cut in the scissors to cut various objects using the blades 4. It is provided with a spring 10 for pressing the blade members (6,7) in the mutually adjacent direction, so that when the user releases the handle (2), the blade members (6,7) are automatically rotated in the adjacent direction to be folded A new structure of scissors is provided to prevent this from happening.

Description

Scissors {scissors}

The present invention relates to scissors, and more specifically, as the use of scissors for a long time, the hinge shaft for hinge-bonding the blade members of the scissors bend, or the thread formed around the hinge shaft is worn out to fix the hinge shaft It is about the scissors of the new structure which can prevent it.

In general, the scissors are configured by hinge-pairing a pair of blade members having a handle on one side and a blade formed on the other side, by rotating the user in the direction to open the blade member or the folding member, that is, It is designed to cut various objects by using a blade, by scissoring.

By the way, the scissors are configured to hinge through the blade members by forming a through hole in the hinge engaging portion of the blade member and fitting the hinge shaft into the through hole. And, in the case of expensive scissors such as hairdressing scissors, by screwing the nut-shaped knob to the end of the hinge shaft formed with a screw in the circumference, by turning or locking this knob, it is possible to adjust the degree of close contact with the blade members. It is configured to be.

However, in the case of using the scissors for a long time, the thread formed around the hinge shaft is worn out by contacting the inner circumferential surface of the through hole, so that the strength of the hinge shaft is gradually weakened, and in severe cases, the middle portion of the hinge shaft is bent so that the scissors cannot be used. There was a problem. Particularly, in the case of beauty scissors, in some cases, a large amount of hair should be cut at once, and at this time, the hinge axis is bent due to excessive force applied to the hinge axis while the scissors are twisted.

In addition, these scissors are used to lock or loosen the knob frequently according to the user's preference. As a result, the inner circumferential surface of the knob and the screw portion of the hinge shaft are worn down, so that the knob is loose, so that the knob can be easily released or escaped from the hinge shaft. There was a problem.

The present invention is to solve the above problems, the purpose of the present invention is to use the scissors for a long time, the hinge shaft for hinge-bonding the blade member of the scissors is bent, or the thread formed around the hinge axis is fixed to the hinge shaft It is to provide a new structure of scissors to prevent the knob from falling out.

According to the present invention, a pair of blade members 6 and 7 having a handle 2 at one side thereof and a blade 4 at the other side thereof, and a through hole formed at an intermediate portion of the blade members 6 and 7. A hinge shaft 12 fitted to (8,10) to hinge the blade members 6 and 7 to each other, and a knob coupled to an end of the hinge shaft 12 to fix the hinge shaft 12. In the scissors configured to include (14), the inner end of the knob 14, the coupling end pipe 16 is inserted into the through holes (8, 10) is extended, so that the circumference of the hinge shaft 12 Scissors of a new structure are provided to prevent direct contact with the inner surfaces of the through holes 8, 10.

According to another feature of the present invention, the hinge shaft 12 is cut in both sides in the longitudinal direction from the tip portion thereof, when the screw formed on the hinge shaft 12 or knob 14 is worn, the hinge shaft 12 Scissors are provided, characterized in that the ends of the hinges 12 are brought into close contact with the threads of the hinge shaft 12 and the knob 14 to prevent the knob 14 from being released or dislodged.

Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows.

1 to 3 illustrate the scissors according to the present invention, which illustrates the beauty scissors used when painting the hair charcoal.

The scissors are provided with handles 2 on one side and first and second blade members 6 and 7 having blades 4 formed on the other side thereof, and through holes formed in the middle of the blade members 6 and 7. A hinge shaft 12 fitted to (8,10) to hinge the blade members 6 and 7 to each other, and a knob coupled to an end of the hinge shaft 12 to fix the hinge shaft 12. It is composed of (14), and the user can cut the hair sandwiched between the blade (4) by grasping the handle (2), the same as the conventional hairdressing scissors. At this time, the hinge shaft 12 is fitted on the outside of the first blade member 6, the end thereof extends to the through hole 10 of the second blade member 7, the knob 14 is configured in the shape of a nut And screwed to the end of the hinge shaft 12.

In addition, a coupling end pipe 16 inserted into the through holes 8 and 10 extends on the inner surface of the knob 14. The coupling end pipe 16 has a screw formed therein and is screwed to the outside of the hinge shaft 12. When the knob 14 is screwed to the hinge shaft 12, the end portion thereof has a first end. It extends up to the through hole 8 of the blade member 6 and has a length sufficient to be inserted.

In addition, the coupling end pipe 16 has a cross-sectional shape of a quadrangular shape, and the through hole 8 of the first blade member 6 also has a cross-section of a quadrangular shape. Inserted into and coupled to the through hole 8 of the blade member 6, the first blade member 6 and the coupling end pipe 16 are configured to move integrally. At this time, the coupling end pipe 16 is chamfered corner portion, it is configured so that the second blade member 7, the coupling end pipe 16 is fitted can be smoothly rotated.

Therefore, since the hinge shaft 12 does not directly contact the inner circumferential surfaces of the through holes 8 and 10 by the coupling end pipe 16, even if the scissors are used for a long time, the threads of the hinge shaft 12 may be worn or damaged. In this case, the strength of the hinge shaft 12 can be prevented from weakly easily bent. In particular, since the end of the coupling end pipe 16 is inserted into the through hole 8 of the first blade member 6 and coupled, the knob 14 and the first blade member 6 are fixed to each other as a single object. , Since the coupling end pipe 16 and the first blade member 6 absorb the external force acting on the hinge shaft 12, there is an advantage that the hinge shaft 12 can be more surely prevented from bending.

In addition, as shown in FIG. 3, the hinge shaft 12 has a slot 18 formed in the front end thereof in the longitudinal direction, and is cut in both sides about the slot 18 to open the front end in both sides. It is configured to be. Therefore, when the screw formed on the hinge shaft 12 or the knob 14 is worn out and loosened, the knob shaft 12 is brought into close contact with each other by bringing the ends of the hinge shaft 12 into close contact with each other. Since the (14) can be prevented from being released or escaped, there is an advantage that the scissors can be used for a long time.

As described above, according to the present invention, the coupling end pipe 16 is inserted into the through holes 8 and 10 of the blade members 6 and 7 on the inner surface of the knob 14, By configuring the circumferential surface to prevent direct contact with the inner surfaces of the through holes 8 and 10, as the scissors are used for a long time, the hinge shaft 12 that hinges the blade members of the scissors is bent, The scissors of the new structure can be provided to prevent the thread 14 formed around the hinge shaft 12 from being worn out so that the knob 14 fixing the hinge shaft 12 can be pulled out.
