Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the structure of the pivot portion of scissors.

(Prior Art) In scissors consisting of a pair of scissor components in which a blade body and a handle body are continuously formed in the front and rear, the pair of scissors components are pivoted at the intersection between the blade body and the handle body. It is worn. In scissors such as pruning shears, the pivot connection is generally made using metal bolts and nuts.

(Problem to be solved by the invention) However, in the above-mentioned scissors, metal bolts and nuts are used to pivot the pair of scissor components, so when not in use, the scissors can be placed on a desk, etc. In such cases, the surface of the desk, etc. may come into contact with the head of the bolt or the nut, causing scratches on the surface of the desk, etc., and the touch of the desk, etc., may not be good to the touch. In addition, the metal bolts and nuts are susceptible to rust,
It also looks inferior in appearance. Furthermore, inconvenient situations such as loosening of bolts and nuts occurred during the work.

The present invention aims to eliminate such drawbacks.

(Means for Solving the Problems) A pair of scissors consisting of a pair of scissors components having a blade body and a handle body, the pair of scissors components being pivotally connected with metal bolts and nuts, and having a metal bolt and a nut. Scissors characterized in that the bolt head and nut are capped with a synthetic resin cap.

(Function) When using the scissors of the present invention, when placing the scissors on a desk etc. when not in use, or when holding the scissors with one hand, the synthetic resin cap is used instead of the hard metal bolt or nut. It comes into contact with surfaces such as desks or hands.

(Example) Hereinafter, the present invention will be explained with reference to the embodiments shown in the drawings.

A and B are a pair of scissor constituent members that constitute the scissors, and the blade bodies 1a and 1b and the handle body 2a and
2b is formed.

3 is a metal bolt that pivotally connects the pair of scissors constituent members A and B, 3a is a bolt head, and 3b is a bolt shaft. 4 is a metal nut for fastening the bolt 3. A cap 5 is made of synthetic resin and caps the head 3a of the bolt 3, the nut 4, and the portion A of the bolt shaft 3b protruding from the nut 4. The cap 5 preferably has a hemispherical shape. Furthermore, it is aesthetically preferable if the cap is made of a synthetic resin having a color such as orange or red.

These pair of scissors constituent members A and B are arranged so that the pivot holes 6a and 6b bored at the intersection of both members A and B are in contact with each other in a state where they are opposed to each other. The bolt 3 that continuously passes through the shaft 6b is inserted, and the nut 4 is attached to the bolt shaft 3b, thereby being pivotally connected. In this case, the bolt 3 is formed into a cylindrical shape in which the portion through which the holes 6a and 6b are inserted can slide on the peripheral walls of the holes 6a and 6b, and the nut 4 is screwed into the male threaded portion of the protruding tip. Both components are pivotally connected to each other so as to be rotatable about the bolt shaft 3b. A portion of the bolt head 3a, nut 4, and bolt shaft 3b that protrudes from both structural members after being pivoted is covered with a cap 5 made of synthetic resin. The reason why we did this after pivoting was because if we used bolts 3 and nuts 4 covered with caps 5 made of synthetic resin in advance, we would not be able to securely fasten both parts, which would result in looseness when cutting. Because it will be.

(Effects of the invention) According to the invention, the part of the bolt and nut used for pivoting that protrudes from both structural members constituting the scissors is covered with a cap made of synthetic resin. It will not damage the top of your desk even when placed on top of a desk, and it will not damage your hands when shaking off leaves and twigs with scissors. By covering the bolts and nuts with the cap, loosening during work can be prevented. It is possible to prevent rust on nuts, etc., and even if rust occurs on nuts, etc., it will not be exposed, so it can be kept in a good appearance. A design effect can be achieved by coloring the cap with a good color scheme. You can use off-the-shelf metal bolts and nuts that are commonly used.
It does not reduce the strength of nuts, etc., and the scissors will not be damaged even if the front or back side of the scissors is placed on a desk. It also has other remarkable effects.
