Abstract

An improved hand grip 10 comprises a molded base structure 14 having a cap 16 and a body 18 for forming an inner layer 22 and an outer layer 24 molded on the body 18. The body 18 has an inner surface 26 with a plurality of radial grooves 28 spaced apart along the length of the body 18 in the form of groove clusters 30.

Claims

1. An improved hand grip, comprising a molded base structure having a cap and a body for forming an inner layer, and an outer layer disposed on said body, said body having an inner surface with a plurality of radial grooves therein for facilitating vibration damping.

2. The improved hand grip according to claim 1, wherein said plurality of radial grooves on said inner surface of said body are spaced apart axially along a length of the grip at distances to form groove clusters.

3. The improved hand grip according to claim 1, wherein said inner and outer layers comprise a rubber material.

4. The improved hand grip according to claim 1, wherein said inner layer has a durometer value in the range of about 55 to about 75 on a Shore A scale.

5. The improved hand grip according to claim 4, wherein said outer layer has a durometer value in the range of about 28 to about 48 on a Shore A scale.

6. The improved hand grip according to claim 5, wherein said inner and outer layers comprise a rubber material.

7. The improved hand grip according to claim 1, wherein said plurality of radial grooves on said inner surface of said body are spaced apart at equal distances on the grip.

8. The improved hand grip according to claim 6, wherein said grip comprises a golf club grip.

9. In a molded golf club grip, the improvement comprising a plurality of radial grooves on an inner surface thereof for enhanced vibration damping.

10. A method for making an improved hand grip, comprising the steps of:

providing a molded base structure having a cap and a body for forming a first inner layer having a durometer value ranging from about 55 to about 75 on a Shore A scale;

providing a plurality of radial grooves on an inner surface of the body; and

molding an outer layer on the body, the outer layer having a durometer value ranging from about 28 to about 48 on a Shore A scale.

11. A method as recited in claim 10, wherein the inner and outer layers are formed of a rubber material.
