Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a grip for a golf club.

Conventional technology and problems Traditionally, natural rubber or synthetic rubber (styrene-butadiene rubber, butadiene rubber, isobrene rubber, etc.) has been used as grips for golf clubs.
The so-called rubber grip, which is manufactured by vulcanization molding of a material whose main ingredients are the like, and the so-called leather grip, which is made by wrapping natural leather or synthetic leather in a spiral shape around the surface of the club shaft, are widely known.
However, in the case of the above-mentioned rubber grips and leather grips, it was difficult to distinguish the degree of wear on the grip surface, and as the amount of wear increased with long-term use, the grip surface became slippery.
This caused the swing to become unstable. Furthermore, the golf club may slip out of the user's hand during the swing, which is dangerous.

On the other hand, there are two-layer grips with an inner layer made of synthetic resin and an outer layer made of synthetic rubber for the purpose of weight reduction, and two-layer structure grips with an inner layer made of soft rubber and an outer layer made of hard rubber for the purpose of increasing the cushioning effect. has also been known for a long time. However, these grips are not intended to detect the degree of wear on the outer layer; therefore, the outer and inner layers are generally made of the same colored material, making it difficult to distinguish the degree of wear on the grip surface. It was becoming difficult.

Purpose of the Invention In view of the above-mentioned drawbacks of the prior art, it is an object of the present invention to provide a grip for a golf club in which the degree of wear on the grip surface can be easily and clearly discerned.

Structure of the invention According to the invention, the cylindrical grip main body has a multilayer structure consisting of at least two or more layer parts concentric with the outer peripheral surface thereof, and the two adjacent layer parts have different colors. This is achieved by a grip for a golf club characterized by the following.

Embodiments of the invention Hereinafter, embodiments of the invention will be described with reference to the drawings.

1 to 6 show an embodiment of the present invention. First, referring to FIGS. 1 to 3, the golf club grip 11 attached to the club shaft 10 includes a grip body 12 having a cylindrical shape with a bottom.
2 is two layer parts 13 and 14 concentric with the outer peripheral surface.
It has a multilayer structure consisting of two layer parts 1 and 1.
3 and 14 are colored in different colors. Although the colors can be freely selected, here, the inner layer portion 13 is colored red and the outer layer portion 14 is colored black.

Here, the two layer parts 13, 14 are based on styrene-butadiene rubber, and the grip is manufactured by a vulcanization molding method. To explain this manufacturing method, first, a vulcanizing agent, a pigment, a vulcanization accelerator, a reinforcing agent, etc. are added to styrene-butadiene rubber, the mixture is kneaded, and then rolled out with a roller to form a rubber sheet. In this case, if a red pigment is added, a red rubber sheet will be obtained, and if a black pigment is added, a black rubber sheet will be obtained. Next, a red rubber sheet, which will become the inner layer, is wrapped around the core of the grip mold, and a black rubber sheet, which will become the outer layer, is further covered around its outer periphery. At this time, by changing the number of turns of the rubber sheet, the inner layer portion and the outer layer portion can be made to have arbitrary thicknesses. Thereafter, this grip material is placed in a grip mold, and heated and pressurized to vulcanize and mold the grip.

When the surface of the grip 11 constructed as described above is worn out due to long-term use, the black outer layer portion 14 is worn out and becomes red, as shown in FIGS. 4 to 6, for example. Inner layer part 13
This makes it possible to clearly distinguish the degree of wear on the grip surface. Therefore, it becomes easy to judge when to replace the grip, and the grip can be replaced before the grip surface becomes slippery.

Although one embodiment has been described above, the present invention is not limited to only the aspects of the above embodiment.
For example, as shown in FIG.
It is also possible to have a multilayer structure consisting of three layer parts 15, 16, and 17. In this embodiment, the three layer sections 15, 16, and 17 may all have different colors, but the outermost layer section 15 and the innermost layer section 17 may have the same color and the middle layer section 16 may have a different color. It's okay. With such a multilayer structure of three or more layers, it becomes possible to detect the degree of wear on the grip surface step by step.

Further, the outer layer of the grip body may have a design pattern made of slits or irregularities. Further, the outer shape of the grip main body is not limited to a circular cross section, but may be, for example, a polygonal cross section.

Further, the material for each layer of the grip main body is not limited to one having styrene-butadiene rubber as a main component, but other rubber materials, synthetic resins, etc. can be arbitrarily selected and used.

Effects of the invention As is clear from the above explanation, the grip for a golf club according to the invention has a cylindrical grip main body having a multilayer structure consisting of at least two or more layers concentric with the outer peripheral surface of the grip body, and two layers adjacent to each other. Since the layer portions are characterized by different colors, it is possible to provide a grip for a golf club in which the degree of wear on the grip surface can be easily and clearly distinguished. Therefore, it is now possible to easily judge when it is time to replace the grip, and by replacing the grip before the grip surface becomes slippery, it is possible to stabilize the swing and prevent the club shaft from coming off during the swing. This means that you can do it.
