Abstract

A golf club head having integrally attached weight members is disclosed and claimed. The club head body defines at least a toe chamber and a heel chamber. Weights of variable mass are positioned within the chambers, moving the club head center of gravity back and down.

Claims

1. A wood-type golf club head, comprising:

a body including a face, a sole, a crown, and a skirt, wherein the body comprises a toe and a heel and defines an interior volume;

a first elongated chamber within the body accessible from the exterior at the heel and extending towards the toe;

a first weight member positioned within the first chamber;

a second elongated chamber within the body accessible from the exterior at the toe and extending towards the heel,

a second weight member positioned within the second chamber;

wherein one of the first and second weight members is located closer to the face than the other.

2. The golf club head of claim 1, wherein the first and second elongated chambers extend longitudinally substantially parallel to the face.

3. The golf club head of claim 1, wherein the face is a face insert coupled to the body.

4. The golf club head of claim 1, wherein at least one of the first and second weight members comprises tungsten.

5. The golf club head of claim 1, wherein the golf club head has a center of gravity located from 10 millimeters to 50 millimeters behind the face.

6. The golf club head of claim 5, wherein the golf club head has a center of gravity located from 20 millimeters to 35 millimeters behind the face.

7. The golf club head of claim 1, further comprising a third weight member coupled to the sole.

8. The golf club head of claim 1, the first weight member has a mass from 1 to 50grams and the second weight member has a mass from 1 to 50 grams.

9. The golf club head of claim 1, wherein the first weight member has a first mass and the second weight member has a second mass greater than the first mass.

10. The golf club head of claim 1, wherein the first weight member has a first mass and the second weight member has a second mass less than the first mass.

11. A wood-type golf club head, comprising:

a body including a face, a crown, and a skirt, the body comprising a toe and a heel and defining an interior volume;

a first chamber accessible from the exterior at a heel side of the body extending toward the toe side of the body;

a first weight member coupled within the first chamber;

a second chamber accessible from the exterior at a toe side of the body extending toward the heel side of the body;

a second weight member coupled within the first chamber,

wherein one of the first or second chambers is located closer to the face than the other chamber, and wherein the first weight member has a first mass and the second weight member has a second mass greater than the first mass.

12. The golf club head of claim 11, wherein the first mass is from 1gram to 50 grams and the second mass is from 1 gram to 50 grams.

13. The golf club head of claim 11, wherein the body further comprises a third weight member.

14. The golf club head of claim 13, wherein the body further comprises a sole, and wherein the third weight member is coupled to the sole.

15. A wood-type golf club head, comprising:

a body including a face, a crown, and a skirt, the body comprising a toe and a heel and defining an interior volume;

a first chamber accessible from the exterior at a heel side of the body extending toward the toe side of the body;

a first weight member coupled within the first chamber;

a second chamber accessible from the exterior at a toe side of the body extending toward the heel side of the body;

a second weight member coupled within the first chamber;

wherein one of the first or second chambers is located closer to the face.

16. The golf club head of claim 15, wherein the first weight member has a first mass and the second weight member has a second mass greater than the first mass.

17. The golf club head of claim 15, wherein the first weight member has a first mass and the second weight member has a second mass less than the first mass.

18. The golf club head of claim 15, further comprising a third weight member coupled to the sole.

19. The golf club head of claim 15, wherein at least one of the first and second chambers are angled relative to the body and face.
