Grip jacket and grip for cutting tool

Abstract

Provided are a grip jacket which facilitates formation of a grip, is not easily separated, and is replaceable, and a grip for a cutting tool which exerts an excellent anti-slip effect, does not require insert molding, is low in cost, and is suitable for housing a folding blade as well. The grip jacket (10) to be mounted on a grip body to complete the grip for a cutting tool is made of an elastic body, and has a single-piece construction, with a pair of jacket side sections (110) interconnected by the intermediary of a jacket back section (120). Each jacket side section (110) has a thick-walled section (111) provided along an inner side of its open end (110c), and the thick-walled section (111) is provided with a fitting pocket (112) to be fitted with a fitting protrusion provided on the grip body side. The jacket back section (120) has, on its inner surface, a positioning protrusion (121) to be inserted into a fitting hole provided at the back section of the grip body for performing positioning.

Description

technical field [0001] The invention relates to a handle sheath and a handle for cutting tools. Background technique [0002] Conventionally, a handle has been provided as a handle of a saw such as a hand saw, and an elastic body is used for a part of the handle and the like for the purpose of anti-slip and the like. [0003] For example, Japanese Utility Model Publication No. 1-41577 (Patent Document 1) discloses a saw handle, in which anti-slip elastic bodies (2) are respectively bonded and installed on a part of both sides of the saw handle (1). [0004] In addition, Japanese Patent Application No. 6-39402 (Patent Document 2) discloses a saw handle, which respectively covers the handle main body (5), (5) divided into two parts with elastic bodies (1), (1), The two are then integrally joined. [0005] In addition, Japanese Patent No. 7-11925 (Patent Document 3) discloses a folding saw handle, which allows elastic body to flow into the lower part of each hard part (6) of ...

AI Technical Summary

Problems solved by technology

In addition, there is a situation where the part of the saw body (5) covering the elastic body (1) is not suitable for setting the saw blade storage groove (8)

[0018] In addition, in the case of the folding saw handle of Patent Document 3, since the soft part (7) at the lower part of each hard part (6) of the handle divided into two parts needs to be implemented by insert molding, molds or molds are required for manufacture. Insert molding work, there are labor and time-consuming problems

Of course, since the two divided parts are integrally fixed with screws, screws are necessary as parts, and there is also a problem that fixing work with screws is required.

[0019] In addition, in the case of the saw handle shown in the aforementioned Patent Document 4, the inside and outside of the substantially U-shaped handle body (4) is still covered by the elastic body (5), and it is substantially difficult to configure it by methods other than insert molding.

In the case of insert molding, the space inside and outside the U-shaped handle body (4) is easily filled with the elastic body (5) to form a thick wall, so there is a disadvantage that the amount of raw materials used increases.

In addition, it is also possible to use a part of the inner space of the U-shaped handle body (4) as a cavity (8) to reduce the amount of raw materials used, but in this case, a core part is required, and the mold relationship becomes complicated. Molding work also becomes complicated

[0020] In addition, the handle of the cutting tool shown in the above-mentioned Patent Document 5 does not use screws, etc., does not perform insert molding, etc., and can cover the entire handle portion (120) of the cutting tool body (100) by dividing the handle body (210), (220), but Handles not suitable for housing of folding blades
