Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grip to be used by covering a handle portion of a bicycle, a grip of sports equipment such as a golf club, a ski pole or the like.

[0002]

2. Description of the Related Art A conventional grip used for this kind of application is composed of the same member as a whole, but when the constituent member is a soft elastic member, it is relatively fit when gripped. However, when it is gripped with a strong grip force, the direction of action of the force is not fixed due to deformation, which not only gives an unstable feeling, but also has the drawback that it is fragile and easily damaged, and when the constituent material is a hard member of synthetic resin, Contrary to the above, on the other hand, there is a lack of a fit when gripped, and there is no conformability when strongly gripped, so there are drawbacks such as scratches on the palm and fingers.

According to the present invention, even though the grip surface is a hard surface, there is a moderate amount of elastic deformation, so that a fit feeling when gripped and a holding stability when firmly gripped can be secured, and palms, fingers, etc. It is an object of the present invention to provide a grip used for a handle, a grip, etc., which is less likely to be scratched.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and an inner surface layer of a shaft hole in which the cross section of the grip body at a right angle to the shaft is closely fixed to the outer periphery of the shaft to be inserted and fixed. And an intermediate layer that covers the outer periphery of the inner surface layer, and an outer peripheral layer that covers the outer periphery of the intermediate layer, the intermediate layer being formed of a shock absorbing member, and the inner surface layer and the outer peripheral layer. The gist is a grip used for a handle, a grip, etc., which is characterized by being formed of a synthetic resin member which is relatively harder than the intermediate layer.

[0005]

As described above, the grip has a three-layer structure perpendicular to the axis, and in particular, the intermediate layer is made of a shock absorbing member and the outer peripheral layer is made of a synthetic resin member relatively harder than the intermediate layer to enhance the outer peripheral strength. In addition, when the grip is gripped, the palm comes into contact with the hard surface, but it is appropriately deformed by the elasticity of the intermediate layer, and acts so as to give an optimal fit and stability of holding.

1 is a front view showing an example of a grip used for a bicycle handle, FIG. 2 is an enlarged sectional view taken along the line AA of FIG. 1, and FIG. It is an expanded sectional view in the AA line of FIG. 1 of another Example.

In the grip of the present invention, as shown in FIGS. 1 and 2, an inner surface layer 3 of an axial hole 2 in which a cross section perpendicular to an axis of a grip body 1 is adhered to an outer periphery of a shaft to be inserted and fixed, and the inner surface layer. The intermediate layer 4 is formed of three layers, that is, an intermediate layer 4 that covers the outer periphery of the intermediate layer 3 and an outer layer 5 that covers the outer periphery of the intermediate layer 4. The intermediate layer 4 is a high-performance thermoplastic elastomer {for example, Lavalon (Mitsubishi Petrochemical Co., Ltd. Company trademark), Septon (trademark of Kuraray Co., Ltd.), Gelnac (trademark of Nippon Automation Co., Ltd.)}, and the inner surface layer 3 and the outer peripheral layer 5 are made of the same hard polyurethane resin or It is made of hard rubber.

The grip constructed as described above is manufactured by sequentially forming a coating by an ordinary insert molding means.

In another embodiment of the grip shown in FIG. 3, the cross section of the grip body 1 perpendicular to the axis is the inner surface layer 3 of the shaft hole 2 which is bonded to the outer circumference of the shaft to be inserted and fixed, and the outer circumference of the inner surface layer 3. Is formed of three layers, that is, an intermediate layer 4 that covers the inner layer 4 and an outer layer 5 that covers the outer periphery of the intermediate layer 4. The intermediate layer 4 is formed of a high-performance thermoplastic elastomer, and the inner surface layer 3 and the outer layer are formed. Reference numeral 5 is a structure in which the intermediate layer 4 is partially penetrated by the communicating slits 6 and is formed of the same hard polyurethane resin.

In the grip having the above-described structure, first, a cylindrical body to be the intermediate layer 4 is molded by injection molding means so as to partially open a communication hole or a communication slit 6 parallel to the axis. It is manufactured by supporting it in the space of the grip molding die in a suspended state and molding it to form the inner surface layer 3 and the outer peripheral layer 5.

The grip of each of the above embodiments is used for a handle of a bicycle, an electric drill, a chainsaw, a golf club,
It is used by fixing it to the grip of tennis rackets, badminton rackets, bats, ski poles, fishing rods, etc.

[0012]

According to the above-described grip of the present invention, the cross section of the grip body perpendicular to the axis covers the inner surface layer of the shaft hole which is bonded to the outer circumference of the shaft to be inserted and fixed, and the outer circumference of the inner surface layer. It is formed of three layers, an intermediate layer and an outer peripheral layer that covers the outer periphery of the intermediate layer, the intermediate layer is formed of a shock absorbing member, and the inner surface layer and the outer peripheral layer are synthetic resins that are relatively harder than the intermediate layer. By forming it with a member, while strengthening the outer circumference strength, when gripping the grip, the palm touches the hard surface, but it is appropriately deformed by the elasticity of the intermediate layer to give an optimal fit and holding stability. it can.

Further, since the inner surface layer is also made of a synthetic resin member which is relatively harder than the intermediate layer, the fixing to the shaft or the like to be inserted and fixed becomes reliable.

Further, if the inner surface layer and the outer peripheral layer are formed so as to partially penetrate the intermediate layer, it is possible to provide a grip excellent in durability without rotating each layer individually.
