Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 292 words
A golf club having a high radius of gyration comprising a hollow shaft, a hosel, and a club head; said club head comprising first and second portions, said first portion being of a metallic material having a high modulus of elasticity, said first portion forming an integral sole plate and between 30 to 100% of the face area of the club head, said sole plate covering the complete bottom surface of the club head, said sole plate having a first upwardly directed integral member forming an attachment post over which said hollow shaft snugly fits, and a second upwardly directed integral member forming a guiding post in assembly of the club head, said sole plate including a peripherally extending ridge having a height greater than the thickness of the center of the sole plate and being a minor portion of the total height of the club head, said second portion of said club head being of a non-metallic material having a density substantially less than the density of said first portion such that said second portion forms a minor portion of the weight of the club head, said second portion being secured to said first portion along the peripherally extending ridge and along said guiding post, said second portion being spaced from said first portion in the area of the face plate to form a cavity therebetween, said second portion having an aperture extending through a neck portion thereof, said hosel being adapted to snugly fit within said aperture over said shaft and extend to the sole plate, said first portion and second portion of said club being located with respect to each other so the relative weights and distributions of the first and second portions create a high radius of gyration.
Claim 2
