Abstract
Abstract A golf club is described, the golf club having a grip with a weighted element integrally attached to the distal end. The weighted element is fixedly secured within the grip and is shaped in the form of an inverted cup, with flanges described from a central spherical portion. The grip itself is of a resilient material and completely encloses the weighted element, including both sides of the flanges. When the grip is secured on the shaft of a golf club, this completely symmetrical weighted grip provides a leverage and balance that permits greater control and tempo in a golfer's swing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
192 words
A golf club comprising: a shaft, a club head on one side of said shaft and a grip portion on the distal end of said club opposite said club head; said shaft having a certain distribution of weight; said grip portion including a weight assembly on said distal end of said shaft; said weight assembly comprising at least two longitudinal portions located about said distal golf shaft end in spaced relationship, each longitudinal upper portion having a portion positioned entirely behind said shaft, the combined mass of said longitudinal portions being disposed equally about said shaft end, said longitudinal portions being spaced from one another, thereby creating a gap, said gap being filled with resilient material to permit limited expansion during assembly; said upper portions each having a flange depending therefrom, said flanges surrounding said shaft at said distal end; said weight assembly being encompassed by a resilient grip material, and adhesively secured to said shaft, thereby maintaining the relative immobility of said weight assembly and preventing movement of said weight relative to said shaft; whereby said weight displaces the weight distribution on said shaft to a point closer said distal end.
Claim 2
Dependent Claim
192 words
A golf club comprising: a shaft, a club head on one side of said shaft and a grip portion on the distal end of said club opposite said club head; said shaft having a certain distribution of weight; said grip portion including a weight assembly on said distal end of said shaft; said weight assembly comprising at least two longitudinal portions located about said distal golf shaft end in spaced relationship, each longitudinal upper portion having a portion positioned entirely behind said shaft, the combined mass of said longitudinal portions being disposed equally about said shaft end, said longitudinal portions being spaced from one another, thereby creating a gap, said gap being filled with resilient material to permit limited expansion during assembly; said upper portions each having a flange depending therefrom, said flanges surrounding said shaft at said distal end; said weight assembly being encompassed by a resilient grip material, and adhesively secured to said shaft, thereby maintaining the relative immobility of said weight assembly and preventing movement of said weight relative to said shaft; whereby said weight displaces the weight distribution on said shaft to a point closer said distal end.
Claim 3
Dependent Claim
21 words
The golf club of claim 1 wherein an adhesive means is disposed directly adjacent said shaft along the entire grip portion.
Claim 4
Dependent Claim
20 words
The golf club of claim 1 wherein said flanges and said resilient material provides a tight fit on said shaft.
Claim 5
Dependent Claim
29 words
The golf club of claim 1 wherein said weight assembly has a mass distributed equally about a central axis, said axis corresponding to the central axis of said shaft.
Claim 6
Dependent Claim
46 words
The golf club of claim 1 wherein said weight assembly has a plurality of pin heads extending from an upper face of said upper portion, said pin heads being covered by said resilient grip material thereby impeding movement of said weight assembly on said golf club.
Claim 7
Dependent Claim
177 words
A golf club comprising: a shaft, a club head on one side of said shaft and a grip portion on the distal end of said club opposite said club head; said shaft having a fulcrum point intermediate said club head and said grip; said grip portion including a weight assembly on said distal end of said shaft; said weight assembly having a central portion positioned entirely behind said shaft; said central portion having an opening therethrough and an outer periphery, the mass of said central portion being disposed equally about said opening, said central portion having a flange depending from said outer periphery of said central portion and surrounding said shaft at said distal end; a plurality of pins extending from an upper face of said central portion; said weight assembly being encompassed by a resilient grip material, including said pins, thereby maintaining the relative immobility of said weight and preventing lateral movement of said weight relative to said shaft; whereby said weight displaces said fulcrum point on said shaft to a point closer said distal end.
Claim 8
Dependent Claim
177 words
A golf club comprising: a shaft, a club head on one side of said shaft and a grip portion on the distal end of said club opposite said club head; said shaft having a fulcrum point intermediate said club head and said grip; said grip portion including a weight assembly on said distal end of said shaft; said weight assembly having a central portion positioned entirely behind said shaft; said central portion having an opening therethrough and an outer periphery, the mass of said central portion being disposed equally about said opening, said central portion having a flange depending from said outer periphery of said central portion and surrounding said shaft at said distal end; a plurality of pins extending from an upper face of said central portion; said weight assembly being encompassed by a resilient grip material, including said pins, thereby maintaining the relative immobility of said weight and preventing lateral movement of said weight relative to said shaft; whereby said weight displaces said fulcrum point on said shaft to a point closer said distal end.
