JPS5914143Y2 - Handle of a handy tool with a convex pattern on the mouthpiece - Google Patents

Description

[Detailed Description of the Invention] This invention relates to the handle of a handy tool such as a pocket knife, a hunting knife, etc., in which a plastic material formed in a convex pattern is embedded in the metal part of the pommel head, that is, the base part.

Regarding a handle in which a colored pattern of plastic is embedded in the grip of the handle of a utility tool, there is an idea previously proposed by the applicant in Utility Model Application No. 54-59662.

However, although the invention of Utility Model Application No. 54-59662 fixes a color pattern on the grip of the handle of a handy tool, it has the disadvantage that it cannot be seen when the handy tool is actually used.

This idea fixes the color pattern as a convex pattern on the base of the handle, which compensates for the above-mentioned drawbacks, and at the same time makes the surface of the base non-slip, eliminating the risk of bending or folding the blade. The purpose of providing handles for useful tools was made in 1973.
This invention relates to an improvement of the invention of No. 4-59662.

This invention will be explained in detail based on illustrated embodiments.

In FIG. 1, 1 is a pocket knife 1, and 2 is a blade of the pocket knife 1.

3 is the handle of the pocket knife 1, and 4 is the metal part of the pommel head of the pocket knife 1, that is, the mouthpiece.

41 is a plastic material fixed to both surfaces of the base portion 4 to form a pattern.

The plastic material 41 is made by pouring a molten material into linear grooves 42 dug at an appropriate depth on both surfaces of the mouthpiece 4.
After that, it is cured and fixed at room temperature.

In this case, the plastic material 41 is formed with a protrusion 44 slightly higher than the surface of the base portion 4 .

Furthermore, when fixing a complex pictorial pattern or flower pattern instead of a simple line pattern as in the illustrated embodiment, a protrusion 44 is provided on the cross section of each linear portion constituting the pattern. It is formed to prevent slipping when using part 2.

Moreover, the linear groove portion 4 before the plastic material 41 is introduced into the linear groove portion 4
A cut groove part 43 is provided on a part or all of the bottom edge of the base part 2 so as to cut into the side wall of the mouthpiece part 4, so that the plastic material 41 is not easily peeled off.

In addition, the mouthpiece 4 of the pocket knife 1 etc. is usually made of copper-based non-ferrous metal material, and has a metallic color with a slight yellowish tint. It is formed using colored materials to enhance its aesthetic appearance.

Furthermore, since the cap part 4 is made of a metal material, if it is difficult to form the linear groove part 42, an appropriate method can be used instead of forming the linear groove part 42 on the line of the diagram forming the pattern. A pattern is formed by continuous bottomed holes 45 spaced apart at a certain interval.

Even in this case, the plastic material 41 forms a protrusion 44 that protrudes slightly higher than the surface of the mouthpiece 4, and also forms a part or all of the bottom edge of each bottomed hole 45 on the side wall of the mouthpiece 4. A notched groove portion 43 is formed to cut into the plastic material 41 and prevent the plastic material 41 from easily peeling off.

Since this invention is constructed as claimed in the utility model registration based on the above-mentioned embodiment, the colored pattern fixed on the mouthpiece of a handy tool such as a pocket knife is always visible to the user's eyes. Even when using it, it will not be hidden in your hand and out of sight.

In addition, the mouthpiece of a knife, etc. is the part where you apply the most force when bending or folding the blade, or when cutting something with the blade, so it often slips and the tip of your hand is forced into the diameter hole. However, since the protrusion is provided on the base to fix the pattern, the handle of the highly practical tool can be used safely without slipping when using the blade. were able to provide the following.

Claims (2)

[Scope of utility model registration request] (1) In the handle of a handy tool, a pattern is formed by providing a linear groove 42 on the surface of the mouthpiece 4 that forms the metal part of the handle head, and a cut groove 43 is formed in the bottom line of the linear groove 42. The handle of the handy tool is characterized in that a colored plastic material 41 is buried and fixed in such a way that its upper surface protrudes slightly higher than the surface of the mouthpiece 4. (2) The handle of the utility tool according to claim (1), which is formed by continuous bottomed holes 45 with linear grooves 42 spaced apart from each other.
