Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
261 words
A golf putter comprising: A) a shaft having an outer dimension; B) a sleeve having (1) a first end, (2) a second end, (3) a wall connecting said first and second ends together, (4) a longitudinal axis extending between said first and second ends, (5) a bore extending along said longitudinal axis, (6) an inner surface adjacent to said bore and having an inner dimension, and (7) a shaft-receiving hole defined through said wall and intersecting said bore, said shaft-receiving hole having an inner dimension which is larger than said shaft outer dimension; C) an insert element located in said sleeve bore and which includes (1) a first end, (2) a second end, (3) a wall connecting said insert element first end to said insert element second end, said insert element wall having an outer dimension which is smaller than the sleeve element inner dimension, (4) a first flange element on said insert element first end, (5) a second flange element on said insert element second end, (6) said first and second flange elements having outer dimensions which are essentially equal to the inner dimension of said sleeve element adjacent to said sleeve element bore and being attached to said sleeve element bore, (7) a club shaft-receiving hole defined in said insert element wall to be aligned with said sleeve element shaft-receiving hole when said insert element is in place in said sleeve element bore, said insert element shaft-receiving hole having a dimension which is essentially equal to the club shaft outer dimension to attach said insert element to said shaft.
