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, said body having a toe and a heel, said body defining an interior volume;

said body including a first chamber in a heel side of said body extending from said heel portion of said skirt into said body and a second chamber in a toe side of said body extending from said toe portion of said skirt into said body;

a first weight member coupled within said first chamber; and

a second weight member coupled within said second chamber;

wherein;

one of said chambers is located closer to said face than the other of said chambers; and

said first weight member has a mass from 25 grams to 50 grams and said second weight member has a mass from 1 gram to 25 grams.

2. The golf club head of claim 1, wherein said chambers are accessible from outside said body.

3. The golf club head of claim 2, wherein said chambers extend longitudinally into said body substantially parallel to said face.

4. The golf club head of claim 2, wherein said chambers extend inward from said skirt.

5. The golf club head of claim 1, wherein said interior volume has a volume from 100 cubic centimeters to 250 cubic centimeters.

6. The golf club head of claim 5, wherein said interior volume has a volume from 150 cubic centimeters to 200 cubic centimeters.

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

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

9. The golf club head of claim 1, wherein said first weight member has a mass from 1 gram to 50 grams and said second weight member has a mass from 1 gram to 50 grams.

10. 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 said face.

11. The golf club head of claim 10, wherein the golf club head has a center of gravity located from 20 millimeters to 35 millimeters behind said face.

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

13. The golf club head of claim 1, wherein:

said first chamber is not longitudinally aligned with at least one chamber in said toe; and

said second chamber is not longitudinally aligned with at least one chamber in said heel.

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

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

a first chamber in a heel side of the body extending from the heel into the body, wherein a first weight member is coupled within the first chamber;

a second chamber in a toe side of the body extending from the toe into the body, wherein a second weight member is coupled within the second chamber; and

wherein one of the first or second chambers is located closer to the face than the other of the chambers, and wherein the chambers extend inward from the skirt; and

the first weight member has a first mass and the second weight member has a second mass less than the first mass.

15. The golf club head of claim 14, wherein the first mass is from 25 grams to 50 grams and the second mass is from 1 gram to 25 grams.

16. The golf club head of claim 14, wherein the body further comprises a third weight member.

17. The golf club head of claim 16, wherein the third weight is in the sole.
