Abstract

A flexible grip of elastomeric material for a golf club is disclosed. The grip has a groove or pocket therealong on the inner surface and an aperture through the closed end of the grip coincident with the groove. Upon installation of the grip onto the club shaft, a rigid strip is inserted through the aperture and into the groove or pocket. The thickness of the strip is chosen to cause a raising of the outer surface of the grip to form a rib therealong. The interior groove or pocket is formed by a rib formed on a core or mandrel employed in molding of the grip. Upon removal of the mandrel after molding, the groove or pocket and aperture are left in the grip for receiving the rigid strip.

First claim

The invention claimed is:

1. A flexible grip for use on a golf club comprising:
(a) an elongated tubular member formed of elastomeric material having a substantially closed end and an open end adapted for being received over the shaft of the golf club wherein the substantially closed end has an aperture therein on an outer surface of the grip when the substantially close end is closed, and wherein the aperture and closed end are at a longitudinal end of the grip;
(b) a void formed in the tubular member, wherein the void extends at least a portion of the length of the member, wherein the aperture communicates with the void; and,
(c) a strip of rigid material, wherein upon assembly of the grip onto the club shaft, the strip is inserted through the aperture into the void whereby the region of the outer periphery of the grip over the void is raised to form a rib along the outer periphery of the grip.

2. The grip of claim 1 , wherein the strip has a width in the range of 2 to 9 millimeters.

3. The grip of claim 1 , wherein the strip has a thickness in the range of 0.127 to 1.016 millimeters.

4. The grip of claim 1 , wherein the strip is formed of one of (i) metal, (ii) plastic, and (iii) composite material.

5. The grip of claim 1 , wherein the strip has the thickness thereof varied along the length thereof.

6. The grip of claim 1 , wherein the tubular member is formed of elastomeric material having a durometer hardness in the range of 25-75 on the Shore “A” scale.

7. The flexible grip of claim 1 , wherein the void comprises a pocket formed intermediate the inner and outer periphery of the tubular member.

8. The grip of claim 7 , wherein the strip has a width in the range of 2 to 9 millimeters.

9. The grip of claim 7 , wherein the strip has a thickness in the range of 0.127 to 1.016 millimeters.

10. The flexible grip of claim 1 , wherein the void comprises a groove formed on the inner periphery of the tubular member.
