Hair scissors

Abstract

To provide hair scissors in which the blades slide against each other, thereby reducing frictional resistance at the pivot point and improving operability and durability. [Solution] In a hair scissors in which a first blade 1 and a second blade 2 are rotatably connected, a recess is formed on the contact sliding surface of one of the blades, and a low-friction member 3 is fixed in the recess. The surface of the low-friction member is positioned to be substantially flush with the surface of the blade, and the other blade performs an opening and closing operation while sliding against the low-friction member.

Description

Technical Field

[0001] The present invention relates to hairdressing scissors used by barbers or beauticians, and particularly to a structure for reducing frictional resistance at a rotation fulcrum portion where blade bodies slide against each other.

Background Art

[0002] Conventional hairdressing scissors have a structure in which a first blade body and a second blade body are rotatably connected at a rotation fulcrum portion, and perform opening and closing operations while bringing the contact surfaces of both blade bodies into sliding contact with each other.

[0003] However, in this structure, since the metals slide while being in direct contact with each other, wear occurs after long-term use, which may lead to an increase in opening / closing resistance and a decrease in operability. Problem to be Solved by the Invention

[0004] The present invention aims to reduce the frictional resistance at the rotation fulcrum portion in hairdressing scissors whose blade bodies slide against each other, so as to smooth the opening and closing operations, reduce the burden on the user, and improve durability. Means for Solving the Problem

[0005] The hairdressing scissors according to the present invention are hairdressing scissors in which a first blade body and a second blade body are rotatably connected at a rotation fulcrum portion, characterized in that a recess is formed on the contact sliding surface of the first blade body or the second blade body with the other blade body, and a low-friction member is fixed in the recess.

[0006] The low-friction member is disposed in the recess, and is provided such that its surface is substantially flush with the surface of the blade body.

[0007] The low-friction member is made of a fluororesin material, and is fixed in the recess with an adhesive. Effects of the Invention

[0008] According to the present invention, direct sliding contact between metals at the contact portion between the blade bodies is reduced, and the frictional resistance during opening and closing can be lowered.

[0009] This allows for smoother opening and closing of hair scissors, reducing strain on the user's fingers.

[0010] Furthermore, it can suppress wear between the blades and improve the durability of hair scissors. [Brief explanation of the drawing]

[0011] [Figure 1] This figure shows the first blade of the hair scissors according to the present invention and the second blade of the hair scissors according to the present invention.

[0012] [Figure 2] This is a perspective view of the hair scissors according to the present invention in the open state.

[0013] [Figure 3] This is an enlarged view of the pivot point.

[0014] [Figure 4] This is a cross-sectional view AA in Figure 1. [Modes for carrying out the invention]

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0016] The hair scissors according to this invention comprises a first blade 1 and a second blade 2, and these first blade 1 and second blade 2 are rotatably connected at a pivot point by a screw 4.

[0017] A groove 5 is formed on the contact sliding surface of either the first blade body 1 or the second blade body 2 with the other blade body.

[0018] A low-friction member 3 is fixed within the groove 5 using an adhesive. Preferably, the low-friction member 3 is made of a fluororesin material.

[0019] The low-friction member 3 is fixed within the groove 5 with adhesive and is positioned so that its surface is substantially flush with the blade surface.

[0020] In this configuration, when the first blade 1 and the second blade 2 perform opening and closing operations, the other blade moves while sliding against the low-friction member 3. Therefore, direct contact between metals is reduced, and frictional resistance during opening and closing can be reduced.

[0021] The low-friction member 3 is preferably provided near the pivot point and can be formed in an arc shape or a fan shape. [Explanation of Symbols]
