Abstract

Abstract An improved wood-type golf club having a club head in which a recess is formed, the recess being filled with an insert, a dense weighting means within the insert, and a layer of an impact resistant resin within the insert holding the weighting means therein, the weighting means being positioned to provide a center of gravity for the club head which is closer to the leading edge of the club face than in the absence of the weighting means.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 106 words
A wood-type golf club comprising a club head having a recess in the striking area, an insert filling said recess, a dense disk weighting means within said insert, a layer of an impact resistant resin within said insert covering one face and at least a portion of the periphery of said disk, the layer of resin having a smoothly contoured, uninterrupted surface forming part of the striking face of said club, the disk weighting means being positioned to provide a center of gravity for said club head which is closer to the leading edge of the club face than in the absence of said weighting means.
Claim 2
Dependent Claim 106 words
A wood-type golf club comprising a club head having a recess in the striking area, an insert filling said recess, a dense disk weighting means within said insert, a layer of an impact resistant resin within said insert covering one face and at least a portion of the periphery of said disk, the layer of resin having a smoothly contoured, uninterrupted surface forming part of the striking face of said club, the disk weighting means being positioned to provide a center of gravity for said club head which is closer to the leading edge of the club face than in the absence of said weighting means.
Claim 3
Dependent Claim 30 words
The golf club of claim 1 in which said weighting means is positioned so that center of gravity is substantially in the plane which bisects the shaft of the club.
Claim 4
Dependent Claim 29 words
The golf club of claim 1 which includes an annular recess in said insert forwardly of said weighting means for anchoring said layer of resin within said annular recess.
Claim 5
Dependent Claim 38 words
The golf club of claim 1 in which said insert includes an angular taper in said recess for locking said layer of resin therein, said recess having a larger diameter at its base than at its striking face.

Claim 7
Dependent Claim 104 words
A wood-type golf club comprising a club head having a wedge-shaped recess therein in the striking area, a wedge-shaed insert received within said recess, said insert having a bore with a relatively shallow recess at its innermost extremity, a weighting disc overlying and closing off said shallow recess, a layer of adhesive in said shallow recess securing said disc thereagainst, said bore in said insert having a flared portion of increased diameter spaced from said striking face, and a layer of impact resistant resin filling said bore about said disc and having a large diameter radius surface forming the striking area of said club.
Claim 8
Dependent Claim 104 words
A wood-type golf club comprising a club head having a wedge-shaped recess therein in the striking area, a wedge-shaed insert received within said recess, said insert having a bore with a relatively shallow recess at its innermost extremity, a weighting disc overlying and closing off said shallow recess, a layer of adhesive in said shallow recess securing said disc thereagainst, said bore in said insert having a flared portion of increased diameter spaced from said striking face, and a layer of impact resistant resin filling said bore about said disc and having a large diameter radius surface forming the striking area of said club.
Claim 9
Dependent Claim 29 words
The golf club of claim 6 which includes an annular groove in said insert between said shallow recess and said striking face for receiving said resin in locking engagement.
