Abstract

A golf club head comprising a club head body removably coupled at different times with various attachment members in a recess of the club head body. In some embodiments, the golf club head comprises different characteristics when coupled with different attachment members. In some embodiments, different attachment members alter characteristics, such as bounce height, while maintaining other characteristics, such as loft angle and/or bounce angle.

First claim

The invention claimed is:

1. A golf club head comprising:
a partial club head body configured to be removably coupled at different times with a first attachment member and a second attachment member in a recess of the partial club head body;
a back cavity separate from the recess;
a custom tuning port weight comprising a top end;
wherein the partial club head body further comprises a front surface, a rear surface, a top portion, a toe portion, a heel portion, a sole portion having a sole surface, and a trailing edge between the sole surface and the rear surface;
wherein the back cavity comprises a top and a bottom;
wherein the recess is positioned entirely within the sole surface;
wherein a complete club head body is formed when the first or the second attachment member is coupled with the partial club head body to form the sole surface of the golf club head;
wherein the first or the second attachment member comprises at least 40% of the sole surface, wherein the sole surface extends entirely from a toe portion to a heel portion of the complete club head body;
wherein:
when the partial club head body is coupled with the first attachment member, the complete club head body comprises:
a first sole portion;
a loft angle;
a bounce angle; and
a first bounce height;

and
when the partial club head body is coupled with the second attachment member, the complete club head body comprises:
a second sole portion;
the loft angle;
the bounce angle; and
a second bounce height different than the first bounce height;

wherein the back cavity has an opening at the top of the back cavity and is closed at the bottom of the back cavity;
wherein the first attachment member comprises an asymmetric edge;
wherein the second attachment member comprises an asymmetric edge;
wherein the custom tuning port weight is disposed in the back cavity such that the top of the custom tuning port weight is exposed,
and the custom tuning port weight is separate from the recess;
wherein the recess comprises a recess edge;
wherein the recess edge is asymmetric in relation to the asymmetric edge of either the first attachment member or the second attachment member;
wherein the recess edge comprises a recess front edge and a recess rear edge, and the recess rear edge is coincident with the trailing edge of the golf club head;
wherein the first attachment member or the second attachment member is disposed in the recess in a single orientation.

2. The golf club head of claim 1 , wherein the first or the second attachment member comprises at least 50% of the sole surface.

3. The golf club head of claim 1 , wherein the first or the second attachment member comprises at least 60% of the sole surface.

4. The golf club head of claim 1 wherein:
when the partial club head body is coupled with the first attachment member, the complete club head comprises:
a first bounce width;

and
when the partial club head body is coupled with the second attachment member, the complete club head comprises:
a second bounce width different than the first bounce width;
wherein the first or second bounce width is measured from a front of the bounce to a rear of the bounce.

5. The golf club head of claim 1 wherein:
the first attachment member comprises a first weight and the second attachment member comprises a second weight different than the first weight.

6. The golf club head of claim 1 wherein:
the first attachment member comprises a first shape and the second attachment member comprises a second shape different than the first shape.

7. The golf club head of claim 1 wherein:
the first attachment member comprises a first mass distribution and the second attachment member comprises a second mass distribution different than the first mass distribution.

8. The golf club head of claim 1 wherein:
the club head body comprises a first material and the first attachment member and second attachment member comprise the first material.

9. The golf club head of claim 1 wherein:
the club head body comprises a first material and the first attachment member and second attachment member both comprise a second material different from the first material.

10. The golf club head of claim 1 wherein:
the partial club head body comprises a body alignment aid configured to facilitate coupling the partial club head body to the first attachment member or the second attachment member.

11. The golf club head of claim 1 wherein:
the bounce angle is greater than or equal to approximately 0 degrees, or less than or equal to approximately 20 degrees.

12. The golf club head of claim 1 wherein:
the first bounce height is greater than or equal to approximately 0.500 centimeters or less than or equal to approximately 0.635 centimeters.

13. A golf club head comprising:
a partial club head body configured to be removably coupled at different times with a first attachment member and a second attachment member in a recess of the partial club head body;
a back cavity separate from the recess;
a custom tuning port weight comprising a top end;
wherein the partial club head body further comprises a front surface, a rear surface, a top portion, a toe portion, a heel portion, a sole portion having a sole surface, and a trailing edge between the sole surface and the rear surface;
wherein the back cavity comprises a top and a bottom;
wherein the recess is positioned entirely within the sole surface;
wherein a complete club head body is formed when the first or the second attachment member is coupled with the partial club head body to form a sole surface of the golf club head;
wherein the first or the second attachment member comprises at least 40% of the sole surface, wherein the sole surface extends entirely from a toe portion to a heel portion of the complete club head body;
wherein:
when the partial club head body is coupled with the first attachment member, the complete club head body comprises:
a first sole portion having a first sole width;
a loft angle;
a bounce angle; and
a first bounce height;

and
when the partial club head body is coupled with the second attachment member, the complete club head body comprises:
a second sole portion having a second sole width;
the loft angle;
the bounce angle; and
a second bounce height different than the first bounce height;

wherein the back cavity has an opening at the top of the back cavity and is closed at the bottom of the back cavity;
wherein the first attachment member comprises an asymmetric edge;
wherein the second attachment member comprises an asymmetric edge;
wherein the custom tuning port weight is disposed in the back cavity such that the top of the custom tuning port weight is exposed,
and the custom tuning port weight is separate from the recess;
wherein the recess comprises a recess edge;
wherein the recess edge is asymmetric in relation to the asymmetric edge of either the first attachment member or the second attachment member;
wherein the recess edge comprises a recess front edge and a recess rear edge, and the recess rear edge is coincident with the trailing edge of the golf club head;
wherein the first attachment member or the second attachment member is disposed in the recess in a single orientation; and
wherein the first sole width is different than the second sole width.

14. The golf club head of claim 13 wherein:
when the partial club head body is coupled with the first attachment member, the complete club head comprises:
a first bounce width;

and
when the partial club head body is coupled with the second attachment member, the complete c
