Abstract

A weight system including a weight channel formed in the body, the weight channel comprising a first wall and a second wall, an adjustable weight comprising a first member, a second member, and a fastener, the first member and the second member configured such that rotation of the fastener in a first direction forces the first member towards the second member and rotation of the fastener a second direction, opposite the first direction, forces the first member away from the second member; wherein the first member and the second member are configured to engage the weight channel when the fastener is rotated in the second direction, locking the adjustable weight in place in the weight channel; and wherein the adjustable weight is unlocked and free to slide along the channel when the fastener is rotated in the first direction.

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, said body having a center of gravity;
wherein said body comprises a coordinate system with an x-axis located horizontal to said face, a y-axis located vertical to said face, and a z-axis located through said face; and
a weight system configured to adjust a location of said center of gravity of said body;
wherein said weight system comprises:
a weight channel formed in said body, said weight channel comprising a first wall and a second wall, said first wall spaced from said second wall, wherein said first wall comprises an access port along a majority of said weight channel;
an adjustable weight comprising a first member, a second member, and a fastener, said first member comprising a first bore to receive said fastener, said second member comprising a second bore to receive said fastener, said first member and said second member configured such that rotation of said fastener in a first direction forces said first member towards said second member and rotation of said fastener in a second direction, opposite said first direction, forces said first member away from said second member;
wherein said first member and said second member are configured to engage said weight channel when said fastener is rotated in said second direction, locking said adjustable weight in place in said weight channel; and
wherein said adjustable weight is unlocked and free to slide along said channel when said fastener is rotated in said first direction.

2. The golf club head of claim 1 , wherein said second bore of said second member comprises female threads to engage said fastener.

3. The golf club head of claim 2 , wherein said first bore of said first member is smooth allowing said fastener to rotate relative to said first member without translating relative to said first member.

4. The golf club head of claim 1 , wherein said first member comprises a first weight body and a first plurality of engaging arms extending outwards from said first weight body, and said second member comprises a second weight body and a second plurality of engaging arms extending outwards from said second weight body, wherein said first plurality of engaging arms are configured to engage said second wall and said second plurality of engaging arms are configured to engage said first wall when said adjustable weight is locked in place.

5. The golf club head of claim 4 , wherein said first weight body comprises a first weight body width, said first weight comprises a first weight width, said access port comprising an access port width, wherein said first weight width is greater than said first weight body width, wherein said access port width is substantially constant along said channel, wherein said access port width is greater than said first weight body width, and wherein said first weight width is greater than said access port width.

6. The golf club head of claim 4 , wherein said first weight body is configured to abut said second weight body when said adjustable weight is locked in said weight channel.

7. The golf club head of claim 1 , wherein said first wall is substantially parallel to said second wall.

8. A golf club head, comprising:
a body having a face, a sole, a crown, and a skirt joining said face, sole, and crown, said body having a center of gravity;
wherein said body comprises a coordinate system with an x-axis located horizontal to said face, a y-axis located vertical to said face, and a z-axis located through said face; and
a weight system configured to adjust a location of said center of gravity of said body;
wherein said weight system comprises:
a weight channel formed in said body, said weight channel comprising a first wall and a second wall, said first wall spaced from said second wall, wherein said first wall comprises an access port along a majority of said weight channel;
an adjustable weight comprising a first member, a second member, and a fastener, said first member comprising a first bore to receive said fastener, said second member comprising a second bore to receive said fastener, said first member and said second member configured such that rotation of said fastener in a first direction forces said first member towards said second member and rotation of said fastener in a second direction, opposite said first direction, forces said first member away from said second member;
wherein said first member and said second member are configured to engage said weight channel when said fastener is rotated in said second direction, locking said adjustable weight in place in said weight channel;

wherein said adjustable weight is unlocked and free to slide along said channel when said fastener is rotated in said first direction; and
wherein said first member comprises a first weight body and a first plurality of engaging arms extending outwards from said first weight body, and said second member comprises a second weight body and a second plurality of engaging arms extending outwards from said second weight body, wherein said first plurality of engaging arms and said second plurality of engaging arms are configured to engage said weight channel when said adjustable weight is locked in place.

9. The golf club head of claim 8 , wherein said first plurality of engaging arms are configured to engage said second wall and said second plurality of engaging arms are configured to engage said first wall when said adjustable weight is locked in place.

10. The golf club head of claim 9 , wherein said first wall is substantially parallel to said second wall.

11. The golf club head of claim 8 , wherein each of said first plurality of engaging arms and said second plurality of engaging arms comprise protrusions, wherein said first wall and said second wall of said weight channel comprises depressions, wherein said protrusions are configured to engage said depressions when said adjustable weight is locked in place.

12. The golf club head of claim 8 , wherein said first plurality of engaging arms and said second plurality of engaging arms are configured to deflect as said fastener is rotated in a second direction.

13. The golf club head of claim 12 , wherein said first weight body is configured to abut said second weight body when said adjustable weight is locked in said weight channel.

14. The golf club head of claim 8 , wherein said first weight body is located adjacent said first wall, said second weight body is located adjacent said second wall, wherein said first plurality of engaging arms is configured to engage said second wall and wherein said second plurality of engaging arms is configured to engage said first wall when said fastener is rotated in said second direction.

15. A golf club head, comprising:
a body having a face, a sole, a crown, and a skirt joining said face, sole, and crown, said body having a center of gravity;
wherein said body comprises a coordinate system with an x-axis located horizontal to said face, a y-axis located vertical to said face, and a z-axis located through said face; and
a weight system configured to adjust a location of said center of gravity of said body;
wherein said weight system comprises:
a weight channel formed in said body, said weight channel comprising a first wall and a second wall, said first wall spaced from said second wall, wherein said first wall comprises an access port along a majority of said weight channel;
an adjustable weight comprising a first member, a second member, and a fastener, said first member comprising a first bore to receive said fastener, sa
