Golf club grip

Abstract

A golf club grip having a double construction includes a cylindrical inside layer part made of a first rubber having a first hardness, and a cylindrical outside layer part made of a second rubber having a second hardness lower than the first hardness, which part covers the cylindrical inside layer part. The cylindrical inside layer part has a length 1 to 4 cm longer than the length of a half of the entire length of the grip. The cylindrical inside layer part is provided with a plurality of longitudinal projecting strips formed on the outer peripheral surface thereof, and the plurality of longitudinal projecting strips extend from the proximal end side of the cylindrical inside layer part to a portion of 70 to 80% of the entire length of the cylindrical inside layer part along the axis line direction of the cylindrical inside layer part, and are formed at fixed intervals in the circumferential direction. The cylindrical outside layer part is provided with a plurality of circumferential grooves, which are formed at fixed intervals in the axis line direction, on the outer peripheral surface of a portion covering a portion of the cylindrical inside layer part in which the longitudinal projecting strips are formed. The cylindrical outside layer part is provided with a plurality of longitudinal grooves formed on the outer peripheral surface on the distal end side of the circumferential grooves.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This Application claims priorities from Japanese Patent Application No. 2010-259676 filed Nov. 22, 2010, Japanese Patent Application No. 2010-276828 filed Dec. 13, 2010, Japanese Patent Application No. 2011-95899 filed Apr. 22, 2011, and Japanese Patent Application No. 2011-95900 filed Apr. 22, 2011, which are incorporated herein by reference in their entirety.BACKGROUND OF THE INVENTION[0002]The present invention relates to a golf club grip.[0003]Generally, a golf club is formed with a head, a shaft, and a grip. The conventional grip is formed of rubber, the main component of which is, for example, natural rubber. By forming the grip of such a material, the grip feel at the time when a golfer grips a golf club is improved, the anti-slipping effect of the grip is improved, and the resistance to deterioration in the grip is improved.[0004]Japanese Utility Model Application Publication No. 62-9476 discloses a grip that is formed of a materia...

AI Technical Summary

Benefits of technology

[0014]The grip described in Japanese Utility Model Registration No. 2533541 solves problems in Japanese Utility Model Application Publication No. 62-9476 and Japanese Utility Model Application Publication No. 62-82066, and is configured so that because, on the proximal end side of grip gripped by the hand serving as the axis of swing (the left hand for a right-handed person), the inside layer part formed of a soft material is deformed, the grip can be gripped surely, the grip feel is good, and the ball hitting feeling is satisfactorily transmitted from the inside layer part formed of a hard material to the hand on the distal end side (the right hand). However, it has been desired to further improve the grip feel and the ball hitting directivity.

Problems solved by technology

However, when this grip is mounted on the shaft, the solvent for mounting (white gas) takes a long time to vaporize.

To examine this phenomenon, the portion in which the grip is in contact with the shaft was observed by cutting the grip one week after the grip had been mounted, and as a result, it was found that the inner peripheral surface of grip was wet (the solvent did not vaporize sufficiently).

That is, the force for bonding the grip to the shaft was weak.

However, the boundary of color is unclear, for example, because colors are mixed in the joint portion of rubber products having different colors, and no grip in which colors are divided clearly is found.
