Abstract

Some embodiments include a golf club head with a tapered sole weight. Other embodiments for related club heads and methods are also disclosed.

Claims

1. A golf club head comprising:

a sole weight; and

a body comprising;

a sole comprising an interior sole surface and an exterior sole surface; and

a sole weight port comprising;

a port top comprising an interior port top surface and an exterior port top surface, the exterior port top surface having a taper of plus or minus approximately 1-30 degrees with respect to a horizontal plane when the golf club head is at an address position, and the interior port top surface having a taper of plus or minus approximately 1-89 degrees with respect to the exterior port top surface;

one or more port side walls; and

a weight-receiving cavity opening to the exterior sole surface and bounded by the exterior port top surface and the one or more port side walls,

wherein the sole weight is conformal with the weight-receiving cavity.

2. The golf club head of claim 1, wherein the sole weight port is integral with the sole.

3. The golf club head of claim 1, wherein the body has a volume of no more than 350 cubic centimeters.

4. The golf club head of claim 1, wherein the body comprises a face having a loft angle of approximately 14-45 degrees relative to a vertical plane perpendicular to the horizontal plane when the golf club head is at the address position.

5. The golf club head of claim 1, wherein the body comprises a face having a loft angle of approximately 17-31 degrees relative to a vertical plane perpendicular to the horizontal plan when the golf club head is at the address position.

6. The golf club head of claim 1, wherein the body comprises a front end and a rear end, and the sole weight port is located closer to the rear end than the front end.

7. The golf club head of claim 1, wherein the body comprises a rear end, and a side of the one or more port side walls of the sole weight port extends to the rear end.

8. The golf club head of claim 1, wherein the sole weight comprises a width greater than a maximum thickness of the sole weight.

9. The golf club head of claim 1, wherein the port top includes a threaded screw-receiving portion.

10. The golf club head of claim 1, wherein the sole weight remains uncovered within the sole weight port.

11. The golf club head of claim 1, wherein the sole weight has a different density than the sole weight port.

12. The golf club head of claim 1, wherein the sole weight has a tapered cylindrical shape and comprises a first portion having a first density and a second portion having a second density different from the first density, and the first and second portions are tapered such that a first thickness of the first portion at a first side of the sole weight is greater than a second thickness of the first portion at a second side of the sole weight.

13. A golf club head comprising:

a sole weight comprising a first portion having a first density and a second portion having a second density different than the first density, the first and second portions are tapered such that a first thickness of the first portion at a first side of the sole weight is greater than a second thickness of the first portion at a second side of the sole weight; and

a body comprising;

a sole comprising an interior sole surface and an exterior sole surface; and

a sole weight port comprising;

a port top comprising an interior port top surface and an exterior port top surface;

one or more port side walls; and

a weight-receiving cavity opening to the exterior sole surface and bounded by the exterior port top surface and the one or more port side walls,

wherein the sole weight has a uniform thickness and is conformal with the weight-receiving cavity.

14. The golf club head of claim 13, wherein the body has a volume of no more than 350 cubic centimeters.

15. The golf club head of claim 13, wherein the body comprises a face having a loft angle of approximately 14-45 degrees relative to a vertical plane perpendicular to a horizontal plane when the golf club head is at an address position.

16. The golf club head of claim 13, wherein the body comprises a face having a loft angle of approximately 17-31 degrees relative to a vertical plane perpendicular to a horizontal plan when the golf club head is at an address position.

17. The golf club head of claim 13, wherein the body comprises a front end and a rear end, and the sole weight port is located closer to the rear end than the front end.

18. The golf club head of claim 13, wherein the body comprises a rear end, and a side of the one or more port side walls of the sole weight port extends to the rear end.

19. The golf club head of claim 13, wherein a width of the sole weight is greater than a thickness of the sole weight.

20. The golf club head of claim 13, wherein the port top includes a threaded screw-receiving portion.

21. The golf club head of claim 13, wherein the sole weight remains uncovered within the sole weight port.

22. The golf club head of claim 13, wherein the sole weight has a cylindrical shape and comprises gearing teeth for non-rotatable positioning of the sole weight in the weight-receiving cavity in two or more orientations.

23. The golf club head of claim 13, wherein the sole weight has a regular polygon cross section for non-rotatable positioning of the sole weight in the weight-receiving cavity in two or more orientations.

24. A method comprising:

providing a golf club head comprising;

a sole weight; and

a body comprising;

a sole comprising an interior sole surface and an exterior sole surface; and

a sole weight port comprising;

a port top comprising an interior port top surface and an exterior port top surface, the exterior port top surface having a taper of plus or minus approximately 1-30 degrees with respect to a horizontal plane when the golf club head is at an address position, and the interior port top surface having a taper of plus or minus approximately 1-89 degrees with respect to the exterior port top surface;

one or more port side walls; and

a weight-receiving cavity opening to the exterior sole surface and bounded by the exterior port top surface and the one or more port side walls,

wherein the sole weight is conformal with the weight-receiving cavity.

25. The method of claim 24, wherein providing the golf club head comprises:

providing the golf club head such that the body has a volume of no more than 350 cubic centimeters, and the sole weight has a width greater than a maximum thickness of the sole weight, wherein;

the sole weight remains uncovered within the sole weight port, and

the sole weight has a different density than the sole weight port.
