Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 239 words
A golf club adapted to be mounted on a shaft of a golf club comprising an elongated body formed from a moldable resilient material, said body having a longitudinal axis and an external surface having a substantially circular cross sectional configuration throughout the length of said body, an elongated cavity disposed coaxially to the longitudinal axis of said body and adopted to receive a club shaft, the internal surface of the cavity being substantially circular in cross section and of uniform diameter, said grip at approximately three inches from the upper end thereof having a first diameter of approximately 0.860 inches, the diameter of said grip progressively increasing from said first diameter towards the cap end of said grip at a rate of approximately 0.030 inches per inch of length for a distance of approximately two inches from said first diameter, said diameter continually increasing progressively toward the cap end of said grip to a maximum diameter greater than one inch located adjacent the cap end, the lower two-thirds of said grip decreasing in diameter, from said first diameter, at a rate of 0.02 inches per inch of length of the grip toward the end opposite the end cap, whereby the grip at the upper one-third thereof provides a secure feel for a more confident grip with a golfer's hand and better control of the golf club, and the lower two-thirds thereof discourages overcontrolling the club with other hand.
