Abstract

A golf club head having a body having a first receptacle having a first aperture, a second receptacle having a second aperture, and a first weight retention member affixed to the first receptacle, the first weight retention member having an opening, at least a portion of the first weight retention member extending through the first aperture into the hollow golf club interior; a second weight retention member affixed to the second receptacle, at least a portion of the second weight retention member extending through the second aperture into the hollow golf club interior; and a third weight retention member extending between the first weight retention member and the second weight retention member, the third weight retention member extending through the opening of the first weight retention member, at least a portion of the third weight retention member located in the hollow golf club head interior.

First claim

We claim:

1. A golf club head comprising:
a body having a face, a sole, a crown, and a skirt joining said face, sole and crown;
a hollow golf club interior within said body;
said body having a coordinate system with an x-axis located horizontal to the club face, a y-axis located vertical to the club face, and a z-axis located through the club face;
said body having a center of gravity;
wherein said body comprises a first receptacle, said first receptacle comprising a first aperture;
wherein said body comprises a second receptacle, said second receptacle comprising a second aperture; and
a weight retention system configured to receive a weighted insert, said weight retention system comprising:
a first weight retention member affixed to said first receptacle, said first weight retention member comprising an opening, at least a portion of said first weight retention member extending through said first aperture into said hollow golf club interior;
a second weight retention member affixed to said second receptacle, at least a portion of said second weight retention member extending through said second aperture into said hollow golf club interior; and
a third weight retention member extending between said first weight retention member and said second weight retention member, said third weight retention member extending through said opening of said first weight retention member, at least a portion of said third weight retention member located in said hollow golf club head interior;

wherein a majority of said body, by weight, is formed from a first material having a first density;
wherein said weighted insert comprises a heavy end and a lighter end, wherein said third weight retention member is configured to receive said weighted insert in both a first configuration and a second configuration, wherein said first configuration comprises said heavy end of said weighted insert adjacent said second weight retention member and said second configuration comprises said lighter end of said weighted insert adjacent said second weight retention member;
wherein at least a portion of said first receptacle is located on said sole;
wherein at least a portion of said second receptacle is located on said sole;
wherein said first weight retention member is permanently affixed to said first receptacle and wherein said second weight retention member is permanently affixed to said second receptacle;
wherein said first receptacle includes a first shelf, wherein said first weight retention member includes an inner surface and an outer surface opposite said inner surface, wherein said inner surface of said first weight retention member abuts said first shelf, and wherein at least a portion of said outer surface of said first weight retention member is substantially flush with an external surface of said sole;
wherein said first weight retention member and said second weight retention member are formed from a second material, said second material having a second density and wherein said second density is less than said first density;
wherein said second receptacle comprises a second shelf, wherein at least a portion of said first shelf is angled relative to at least a portion of said second shelf, wherein said third weight retention member couples said first weight retention member to said second weight retention member, forcing said first weight retention member against said first shelf and said second weight retention member against said second shelf and wherein said first shelf and said second shelf are recessed towards said hollow golf club interior from said sole.

2. A golf club head comprising:
a body having a face, a sole, a crown, and a skirt joining said face, sole and crown;
a hollow golf club interior within said body;
said body having a coordinate system with an x-axis located horizontal to the club face, a y-axis located vertical to the club face, and a z-axis located through the club face;
said body having a center of gravity;
wherein said body comprises a first receptacle, said first receptacle comprising a first aperture, wherein at least a portion of said first receptacle is located on said sole;
wherein said body comprises a second receptacle, said second receptacle comprising a second aperture, wherein at least a portion of said second receptacle is located on said sole; and
a weight retention system configured to receive a weighted insert, said weight retention system comprising:
a first weight retention member affixed to said first receptacle, said first weight retention member comprising an opening, at least a portion of said first weight retention member extending through said first aperture into said hollow golf club interior;
a second weight retention member affixed to said second receptacle, at least a portion of said second weight retention member extending through said second aperture into said hollow golf club interior; and
a third weight retention member extending between said first weight retention member and said second weight retention member, said third weight retention member extending through said opening of said first weight retention member, at least a portion of said third weight retention member located in said hollow golf club head interior;

wherein a majority of said body, by weight, is formed from a first material having a first density;
wherein said first weight retention member and said second weight retention member are formed from a second material, said second material having a second density;
wherein said second density is less than said first density.

3. The golf club head of claim 2 , wherein at least a portion of said first receptacle and at least a portion of said second receptacle are located on said skirt.

4. The golf club head of claim 2 , wherein said first receptacle includes a first shelf, wherein said first weight retention member includes an inner surface and an outer surface opposite said inner surface, wherein said inner surface of said first weight retention member abuts said first shelf, and wherein at least a portion of said outer surface of said first weight retention member is substantially flush with an external surface of said sole.

5. The golf club head of claim 4 , wherein said second receptacle comprises a second shelf, wherein at least a portion of said first shelf is angled relative to at least a portion of said second shelf, wherein said third weight retention member couples said first weight retention member to said second weight retention member, forcing said first weight retention member against said first shelf and said second weight retention member against said second shelf.

6. The golf club head of claim 5 , wherein said first shelf and said second shelf are recessed towards said hollow golf club interior from said sole.

7. The golf club head of claim 4 , wherein said second receptacle comprises a second shelf, wherein at least a portion of said first shelf is angled relative to at least a portion of said second shelf, wherein said third weight retention member couples said first weight retention member to said second weight retention member, forcing said first weight retention member against said first shelf and said second weight retention member against said second shelf and wherein said first shelf and said second shelf are recessed towards said hollow golf club interior from said sole.

8. The golf club head of claim 2 , wherein said first weight retention member is permanently affixed to said first receptacle and wherein said second weight retention member is permanently affixed to said second receptacle.

9. The golf club head of claim 2 , wherein said first weight retention member and said second weight retention member are formed fiber reinforced pl
