Abstract

A golf club head is provided with a body that has an address position with a zero degree bounce portion on the sole and a center sole position with a multi-relief surface of the sole having a negative bounce portion. The negative bounce portion may comprise a negative 0.5 to a negative 4.0 degree surface. In one embodiment, the multi-relief surface may comprise the negative bounce portion and a cutaway portion extending to the back of the sole, which may have a depth of about 0.05 to 0.5 inch from a regular sole surface. In another embodiment, the golf club head includes a weight system to adjust the center of gravity. In one embodiment, the weight system is a tube having a weight at one end that may be inserted into the golf club head to move the center of gravity at least forward and backward within 6 mm and up and down within 6 mm. Preferably, the tube is angled downward toward the face by at least 3 degrees.

Claims

1. A golf club head, the golf club head comprising:

a body having a face, a sole, a crown, and a skirt joining the face, sole and crown, the body having a center of gravity;

the 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,

a weight system for the club head, wherein the center of gravity is adjustable along both the z-axis and the x-axis.

2. The golf club head of claim 1, wherein the weight system further comprises a cavity, wherein the cavity is offset from the x-axis.

3. The golf club head of claim 2, wherein the cavity is offset from the x-axis by 0 to 90 degrees.

4. The golf club head of claim 2, wherein the cavity for placement within the club head is formed within a plane defined by the y-axis and the z-axis to adjust the center of gravity, and wherein the tube is angled downward toward the face of the club head by about 3 to about 7 degrees from the z-axis.

5. The golf club head of claim 4, wherein the center of gravity is movable within a 6 mm distance along the z-axis.

6. The golf club head of claim 5, wherein the center of gravity is movable within a 4 mm distance along the z-axis.

7. The golf club head of claim 4, wherein the center of gravity is movable within a 6 mm distance along the y-axis.

8. The golf club head of claim 7, wherein the center of gravity is movable within 12 mm distance along the y-axis.

9. The golf club head of claim 4, wherein the center of gravity is movable within a 2 mm distance along the x-axis.

10. The golf club head of claim 9, wherein the center of gravity is movable within a 0.5 mm distance along the x-axis.

11. A golf club head, the golf club head comprising:

a body having a face, a sole, a crown, and a skirt joining the face, sole and crown, the body having a center of gravity;

the 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,

a weight system for the club head wherein the weight system further comprises a cavity, wherein the cavity is offset from the x-axis by 0 to 90 degrees.

12. The golf club head of claim 11, wherein the weight system comprises two or more cavities all placed along the same plane, offset from the x axis by 0 to 90 degrees.

13. The golf club head of claim 11, wherein the cavities mimic an angle of an insert to connect the cavities.

14. The golf club head of claim 11, wherein the insert is a tube.

15. The golf club head of claim 14, wherein multiple inserts varying in weight may be placed within the tube at various positions to move the center of gravity to the desired location.

16. The golf club of claim 15, wherein the tube is flappable, such that the weight is moveable to the other end of the club head to move the center of gravity for a desired different ball flight.
