Abstract
Abstract An improved golf club comprising a shaft with a head at the tip end and a grip at the butt end, the grip adapted to be held by the hands of the player and formed of an elastomeric material having a plurality of curved grooves, the grooves being in a first set oriented generally axially at the butt end of the grip and therebeyond in a second set generally axially on the bottom surface and generally circumferentially on the top surface and further including a third set of grooves oriented generally circumferentially at the tip end of the grip.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
323 words
A grip positionable over the butt end of a golf club shaft and adapted to be held by the hands of a golfer, the grip having a front surface and a bottom surface oriented on the club shaft such that said front surface is engaged predominantly by both the heel of one hand of the golfer and the inner surface of the thumb of another hand of the golfer and said bottom surface is engaged predominantly by the inner surfaces of the remaining fingers of each of the hands during the address of the golf ball, the grip being fabricated of an elastomeric material and of a generally cylindrical configuration with a generally closed butt end of an enlarged exterior diameter and with an open tip end of a generally reduced exterior diameter for being removably fit over the butt end of the shaft, the interior of the grip being of an essentially common diameter for frictional engagement with the butt end of the shaft over which it is placed, the exterior diameter of the grip being of a decreasing diameter from the butt end to the tip end, the grip being formed with a plurality of smoothly curved, generally continuous grooves oriented to prevent slippage, the grooves being oriented generally axially over the length of the grip adjacent to the butt end for between about 26 percent and about 31 percent of the length of the grip, the grooves being oriented generally circumferentially over the length of the grip adjacent the tip end for between about 19.5 and about 23.5 percent of the length of the grip with between about 38.5 percent and about 47.5 percent of the central length of the grip having generally circumferential grooves on its front surface and generally axial grooves on its bottom surface, said generally circumferential grooves across the central length being curved with their centers of curvature facing the tip end side of the grip.

Claim 3
Dependent Claim
23 words
The grip as set forth in claim 1 wherein the grooves are about 0.025 inches in depth and about 0.030 inches in width.
Claim 4
Dependent Claim
27 words
The grip as set forth in claim 2 wherein the majority of the grooves are spaced between about 0.220 and about 0.240 inches from center to center.
Claim 5
Dependent Claim
208 words
A golf grip adapted to be placed on a club shaft and held by the hands of a golfer, the grip having a front surface and a bottom surface oriented on the club shaft such that said front surface is engaged predominantly by both the heel of one hand of the golfer and the inner surface of the thumb of another hand of the golfer and said bottom surface is engaged predominantly by the inner surfaces of the remaining fingers of each of the hands during the address of the golf ball, the grip having a butt end and a tip end and formed of an elastomeric material having a plurality of smoothly curved continuous grooves, the grooves being in a first set oriented generally axially at the butt end of the grip and therebeyond in a second set generally axially on the bottom surface and generally circumferentially on the front surface, the circumferential grooves being curved with their centers of curvature facing the tip end side of the grip whereby said circumferential grooves serve to substantially preclude axial movement of said hands thereadjacent while said generally axial grooves serve to substantially preclude circumferential movement between said hands and said grip during a stroke of a golf ball.
Claim 6
Dependent Claim
208 words
A golf grip adapted to be placed on a club shaft and held by the hands of a golfer, the grip having a front surface and a bottom surface oriented on the club shaft such that said front surface is engaged predominantly by both the heel of one hand of the golfer and the inner surface of the thumb of another hand of the golfer and said bottom surface is engaged predominantly by the inner surfaces of the remaining fingers of each of the hands during the address of the golf ball, the grip having a butt end and a tip end and formed of an elastomeric material having a plurality of smoothly curved continuous grooves, the grooves being in a first set oriented generally axially at the butt end of the grip and therebeyond in a second set generally axially on the bottom surface and generally circumferentially on the front surface, the circumferential grooves being curved with their centers of curvature facing the tip end side of the grip whereby said circumferential grooves serve to substantially preclude axial movement of said hands thereadjacent while said generally axial grooves serve to substantially preclude circumferential movement between said hands and said grip during a stroke of a golf ball.
Claim 7
Dependent Claim

Claim 9
Dependent Claim
27 words
The golf grip as set forth in claim 4 and further including a third set of grooves oriented generally circumferentially at the tip end of the grip.
Claim 10
Dependent Claim
235 words
A golf club comprising a shaft with a head at a tip end and a grip at a butt end, the grip adapted to be held by the hands of a golfer, the grip having a front surface and a bottom surface oriented on the club shaft such that said front surface is engaged predominantly by both the heel of one hand of the golfer and the inner surface of the thumb of another hand of the golfer and said bottom surface is engaged predominantly by the inner surfaces of the remaining fingers of each of the hands during the address of the golf ball, the grip being formed of an elastomeric material having a plurality of smoothly curved, continuous grooves, the grooves being in a first set oriented generally axially at the butt end of the grip and, therebeyond, in a second set generally axially on the bottom surface and generally circumferentially on the front surface, the circumferential grooves of the second set being curved with their centers of curvature facing the tip end side of the grip and further including a third set of grooves oriented generally circumferentially at the tip end of the grip, whereby the circumferential grooves serve to substantially preclude axial movement of said hands thereadjacent while said generally axial grooves serve to substantially preclude circumferential movement between said hands and said grip during a stroke of a golf ball.
