Abstract

A golf club head with a variable center of gravity is disclosed herein. More specifically, the present invention discloses a wedge type golf club head wherein the center of gravity of the golf club head is adjustable along an x-axis in a heel to toe direction utilizing weights that are placed substantially near a sole portion of the golf club head. The resulting golf club head may generally have a more toe biased center of gravity location, especially when compared to a traditional golf club head.

Claims

1. A wedge type golf club head comprising:

a striking face portion located at a frontal portion of said wedge type golf club head;

a backing portion located behind said striking face portion; and

a sole muscle portion located at a bottom of said wedge type golf club head between said striking face portion and said backing portion, wherein said sole muscle portion further comprises only one of a cavity having an opening and one or more weights shaped to at least partially fit in said cavity, wherein said wedge type golf club head has a center of gravity greater than about 28 mm from an intersection point between a hosel bore axis and a ground plane along an x-axis.

2. The wedge type golf club head of claim 1, wherein said wedge type golf club head has a center of gravity greater than about 30 mm from an intersection point between a hosel bore axis and a ground plane along an x-axis.

3. The wedge type golf club head of claim 2, wherein said wedge type golf club head has a center of gravity greater than about 33 mm from an intersection point between a hosel bore axis and a ground plane along an x-axis.

4. The wedge type golf club head of claim 1, wherein said opening of said cavity is opened towards a bottom sole portion of said sole muscle portion.

5. The wedge type golf club head of claim 4, further comprising a cover, adapted to conceal said cavity.

6. The wedge type golf club head of claim 5, wherein a perimeter of said cover is smaller than a perimeter of said cavity.

7. The wedge type golf club head of claim 1, wherein said opening of said cavity is opened towards a rear portion of said sole muscle portion.

8. The wedge type golf club head of claim 1, further comprising a weight pocket located at an upper toe portion of said backing portion of said wedge type golf club head.

9. The wedge type golf club head of claim 8, further comprising a weight pad, located congruently within said weight pocket.

10. A golf club head comprising:

a striking face portion located at a frontal portion of said golf club head;

a backing portion located behind said striking face portion; and

a sole muscle portion located at a bottom of said golf club head between said striking face portion and said backing portion, wherein said sole muscle portion further comprises only one of a cavity having an opening and one or more weights shaped to at least partially fit in said cavity, wherein said opening of said cavity is opened towards a bottom sole portion of said sole muscle portion, and wherein said golf club head has a center of gravity greater than about 28 mm from an intersection point between a hosel bore axis and a ground plane along an x-axis.

12. The golf club head of claim 10, wherein said one or more weights have a density greater than about 17 g/cm³.

13. The golf club head of claim 12, wherein said one or more weights are biased towards a toe portion of said cavity.

14. The golf club head of claim 12, wherein said one or more weights are biased towards a heel portion of said cavity.

15. The golf club head of claim 14, further comprising a weight pocket located at an upper toe portion of said backing portion of said golf club head.

16. The golf club head of claim 15, further comprising a weight pad, located congruently within said weight pocket.

11. (canceled)

17. A golf club head comprising:

a striking face portion located at a frontal portion of said golf club head;

a backing portion located behind said striking face portion;

a sole muscle portion located at a bottom of said golf club head between said striking face portion and said backing portion, only one of a weight pocket located at an upper toe portion of said backing portion of said golf club head, and

a weight pad, located congruently within said weight pocket,

wherein said wedge type golf club head has a center of gravity greater than about 28 mm from an intersection point between a hosel bore axis and a ground plane along an x-axis.
