DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventional grips used for this kind of application are formed entirely of the same member, but when the constituent members are soft elastic members, they are relatively fit when grasped. However, when gripping with a strong grip force, it deforms and the direction of action of the force is not determined, not only giving a sense of instability, but also has a drawback that it is brittle and easy to break, and when the constituent material is a hard member made of synthetic resin, Contrary to the above, there is a drawback that there is no fit when gripping, and there is no deformation when gripping strongly, so that there is no adaptability and scratches are applied to palms, fingers and the like. In addition, the place of Jiko 59-24618
If the intermediate layer is made of urethane foam resin, the inner layer and outer
What was formed with vinyl chloride resin is known.

According to the present invention, the inner surface layer and the outer peripheral layer are formed more than the intermediate layer.
The same synthetic resin member that is relatively hard
Is partially penetrated continuously into the intermediate layer,
Each layer each other are integrated with the not rotate individually, there is elastic deformation of the modest despite gripping surface is a hard surface, and fit when gripped, held stability when squeezed is ensured It is an object of the present invention to provide a grip that can be used for a handle, a grip portion, and the like, and that does not scratch the palm, fingers, and the like.

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and has a grip body in which a cross section perpendicular to the axis is formed on an inner surface layer of a shaft hole which is tightly fixed to the outer periphery of a shaft to be inserted and fixed. And an intermediate layer that covers the outer periphery of the inner layer, and an outer layer that covers the outer periphery of the intermediate layer. The intermediate layer is formed of a shock absorbing member, and the inner layer and the outer layer In a grip used for a handle, a grip portion, or the like formed of a synthetic resin member relatively harder than the intermediate layer , the inner surface layer and the outer peripheral layer partially penetrate the intermediate layer.
The same synthetic resin that is continuous and relatively harder than the intermediate layer
A gist used for a handle, a grip portion, or the like formed of a member .

[0005]

[Action] The cross section perpendicular to the shaft of the grip as described above to a three-layer structure, comprising in particular a relatively hard synthetic resin member than the intermediate layer an outer layer with the intermediate layer and the shock absorbing member, the inner surface
The outer layer and the outer layer are partially penetrated through the
Formed of the same synthetic resin member that is relatively harder than the
The strength of the inner layer and outer layer is
Each layer can rotate individually by cooperating with the inter-layer.
When the grip, such as the handle and grip portion, is not durable , the palm contacts the hard surface, but it is appropriately deformed by the elasticity of the intermediate layer to provide optimal fit and holding stability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a grip according to the present invention .
FIG. 2 is a front view showing an example of a loop, and FIG.
It is an expanded sectional view.

As shown in FIGS. 1 and 2, the grip of the present invention has an inner surface layer 3 of a shaft hole 2 in which a cross section perpendicular to the axis of a grip body 1 is bonded to the outer periphery of a shaft to be inserted and fixed, and the inner surface layer. 3 an intermediate layer 4 for covering the outer periphery of which is formed of three layers of the outer layer 5 covering the outer periphery of the intermediate layer 4, the inner surface layer and the outer
The peripheral layer is formed by partially penetrating and continuously passing through the intermediate layer.
The intermediate layer 4 is made of the same synthetic resin member which is relatively hard, and the intermediate layer 4 is made of a high-performance thermoplastic elastomer. The inner surface layer 3 and the outer peripheral layer 5 are formed of the same hard polyurethane resin or hard rubber.

[0008] The grip constructed as described above is manufactured by successively forming a cover by a usual insert molding means.

In the grip constructed as described above, first, a cylindrical body serving as the intermediate layer 4 is formed by injection molding means so as to partially open a communication hole or a communication slit 6 parallel to an axis. It is manufactured by supporting this in the space of the grip forming die in a suspended state and forming the inner surface layer 3 and the outer peripheral layer 5.

The grip of the above embodiment is used by being fixed to a handle of a bicycle, an electric drill, a chain saw or the like, or a grip portion of a golf club, a tennis racket, a badminton racket, a bat, a ski pole, a fishing rod or the like. .

[0011]

According to the grip according to the present invention described above, the cross section perpendicular to the axis of the grip body covers the inner surface layer of the shaft hole that is bonded to the outer periphery of the shaft to be inserted and fixed, and the outer periphery of the inner surface layer. An intermediate layer and an outer layer covering the outer periphery of the intermediate layer are formed of three layers, the intermediate layer is formed of a shock absorbing member, and the inner surface layer and the outer peripheral layer are relatively hard synthetic resin than the intermediate layer. In the handle used for the handle formed by the member, the grip part, etc. , the inner surface layer and the outer peripheral layer are
The intermediate layer is partially penetrated continuously to be relatively
Made of the same hard synthetic resin material, inner layer, outer circumference
Each layer is individually rotated by linking the layer strength to the intermediate layer.
When gripping grips such as durable handles and grips that do not move , the palm touches a hard surface but is moderately deformed by the elasticity of the middle layer to give optimal fit and holding stability Can be.

The inner layer and the outer layer are formed of the same synthetic resin member which is relatively harder than the intermediate layer, and the intermediate layer is partially formed of the inner layer.
Since the surface layer and the outer peripheral layer are linked to each other, they can be inserted and fixed , and can be firmly fixed to a shaft or the like.

Further, the inner layer and the outer layer are partially penetrated through the intermediate layer so that the same synthetic resin which is relatively harder than the intermediate layer is formed.
Since it is formed of a grease member, each layer can be integrated with each other to provide a grip having excellent durability without being individually rotated.
