Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
A weighting attachment for removably mounting to a golf club having a head, a shaft and a shank connecting the head to a lower end of the shaft, comprising: a weighted mass having an exterior surface and a bore formed through the mass with end openings along a bore axis to frictionally receive said shank therein; said mass having an access slot formed therein in open communication with the bore including the end openings that evolve laterally and pivotally from the bore axis forming a side entrance opening in the exterior surface of the mass which is transverse to the bore axis; and said access slot having a width sufficient to enable the weighted mass to be inserted onto the shank by initially laterally moving and pivoting the mass with respect to the shaft axis to pass the lower end of the shaft into the side entrance opening and through the access slot to the bore and then moving the mass longitudinally along the shaft until the shank is frictionally received in the bore.
Claim 2
Dependent Claim
174 words
A weighting attachment for removably mounting to a golf club having a head, a shaft and a shank connecting the head to a lower end of the shaft, comprising: a weighted mass having an exterior surface and a bore formed through the mass with end openings along a bore axis to frictionally receive said shank therein; said mass having an access slot formed therein in open communication with the bore including the end openings that evolve laterally and pivotally from the bore axis forming a side entrance opening in the exterior surface of the mass which is transverse to the bore axis; and said access slot having a width sufficient to enable the weighted mass to be inserted onto the shank by initially laterally moving and pivoting the mass with respect to the shaft axis to pass the lower end of the shaft into the side entrance opening and through the access slot to the bore and then moving the mass longitudinally along the shaft until the shank is frictionally received in the bore.
Claim 3
Dependent Claim
36 words
The weight attachment as defined in claim 1 wherein the width of the access slot is great enough to accommodate the diameter of the lower end of the shaft but not the diameter of the shank.
Claim 4
Dependent Claim
38 words
The weight attachment as defined in claim 1 wherein the mass bore is tapered from end to end to correspond to a shank having a progressively increasing diameter from the lower end of the shaft to the head.
Claim 5
Dependent Claim
77 words
The weight attachment as defined in claim 1 wherein the access slot has a first section communicating with the entire length of the bore including the end openings that pivotally evolve from the bore axis in a first plane containing the bore axis and a second section communicating with the first section that laterally evolves from the bore axis to the side opening in a second plane that transversely intersects the bore axis and the first plane.
Claim 6
Dependent Claim
30 words
The weight attachment as defined in claim 4 wherein the access slot forms two opposed L-shaped openings in the extErior surface communicating between the entrance opening and the bore openings.
Claim 7
Dependent Claim
18 words
The weight attachment as defined in claim 1 wherein the weighted mass is elongated along the bore axis.
