Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to scissors, and more specifically, to an improvement of so-called western scissors, in which a pair of blade plates are rotatably attached to each other through eyelets.

<Prior Art> Conventionally, this type of scissors has a pair of blade plates whose fulcrum portions are rotatably connected to each other through eyelets. Therefore, if play occurs after long-term use, the cutting edge moves in the axial direction of the eyelet, resulting in poor sliding and poor cutting quality.

In addition, since the scissors have a pair of blade plates that are pivoted to each other through eyelets, there is a problem in that if the blade edge becomes chipped or curls, the blade plate cannot be replaced and used again. There is also.

<Problems to be solved by the invention> The present invention focuses on western scissors that have the above-mentioned problems, and aims to ensure the sliding of a pair of blade plates despite having a removable shaft-mounted structure. It is to do so.

<Means for solving the problem> The technical means taken to solve the above problem is to create an engaging part that slides a pair of blade plates against each other and engages with the fulcrum part of the blade plate. A pair of scissors is proposed in which an elastic clamp is formed into a U-shaped cross section, and the engaging part of the elastic clamp is engaged with the fulcrum part of a pair of blade plates for clamping.

<Operation> The present invention consists of the above-mentioned means, in which the elasticity of the elastic scoop presses a pair of double-edged blade plates toward the sliding surface side, and while the cutting edges of the blade plates are partially forcedly slid together, The pair of blade plates rotates around the fulcrum part of the blade plate and the engagement part of the elastic arm. Moreover, if the clamping pressure parts of the elastic clamps that clamp the fulcrum parts of the pair of blade plates are expanded in opposite directions, the elastic clamps are removed from the pair of blade plates.

<Example> An embodiment of the present invention will be described based on the drawings.

The pair of blade plates 2, 2 of the scissors 1 are made of stainless steel,
The elastic arm piece 5 is formed symmetrically from steel or other material, and has an engaging part 4 that engages with the fulcrum part 3 of the blade plates 2, 2.

The pair of double-edged plates 2, 2 are configured to slide against each other, and have their cutting edges 2a, 2a curved in a slightly concave shape so that even thick materials can be cut.

The elastic piece 5 is made of a desired elastic material and has a cross section U.
It is formed into a shape of
a is formed to be inclined inward, and an engaging portion 4 that engages with the fulcrum portion 3 of the blade plates 2, 2 is formed on the inner surface of both the clamping pressure portions 5a, 5a.

The engaging portion 4 is a convex portion 4a or concave portion rotatably engaged with a concave portion 3a or a convex portion, which is the fulcrum portion 3 of the pair of blade plates 2, 2.

Therefore, the elasticity of the clamping pressure parts 5a, 5a of the elastic clamp piece 5 causes the pair of double-edged blade plates 2, 2 to slide together and be pressed to both sides, and the cutting edges 2 of the blade plates 2, 2 are pressed against each other.
While forcibly sliding the blade plates 2, 2a together, the recess 3a, which is the fulcrum 3 of the blade plates 2, 2, and the elastic clamp 5
A pair of blade plates 2, 2 rotate around a convex portion 4a, which is an engaging portion 4.

Moreover, if both the clamping pressure parts 5a, 5a of the elastic clamp pieces 5, which clamp the fulcrum parts 3 of the pair of blade plates 2, 2, are expanded in opposite directions, the engaging part 4 of the elastic clamp parts 5 can be expanded in opposite directions. The convex part 4a or the concave part comes off from the convex part of the concave part 3a which is the fulcrum part 3 of the pair of blade plates 2, 2, and the elastic arm piece 5 comes off from the pair of blade plates 2, 2.

<Effects> In the present invention, a pair of blade plates are slid against each other, and the engaging part that engages with the fulcrum part of the blade plates is formed into an elastic arm with a U-shaped cross section. By engaging the fulcrum parts of the pair of blade plates and pressing them together, the elasticity of the elastic clamps presses the blade plates towards the sliding surface side, forcing the blade edges to partially slide against each other. If the pair of blade plates is rotated around the fulcrum part of the blade plate and the engaging part of the elastic lever, no backlash will occur, the sliding condition will be improved, and the cutting edge will be improved.

Furthermore, by expanding the clamping pressure parts of the elastic clamps against the pair of blade plates in mutually opposite directions, the elastic clamps can be easily removed from the blade plates, causing damage to either the pair of blade plates or the elastic clamps. Only the parts that have been removed can be replaced and used, providing a convenient pair of scissors.
