Abstract

One embodiment of a golf club head having movable weights includes a body with a face plate positioned at a forward portion of the golf club head, a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion of the golf club head and a skirt positioned around a periphery of the golf club head between the sole and the crown. Two or more weight ports are formed in the body and at least two weights are configured to be retained at least partially within the weight ports.

Claims

1. A wood-type golf club head comprising:

a body comprising a face plate positioned at a forward portion of the golf club head, a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion of the golf club head and a skirt positioned around a periphery of the golf club head between the sole and the crown, wherein the body defines an interior cavity;

two or more weight ports formed in the body; and

at least one weight having a weight mass and configured to be retained at least partially within one of the weight ports;

wherein the head includes a golf club head center of gravity having a z-axis generally perpendicular to the ground when the head is ideally positioned,

and wherein a golf club head moment of inertia about the head center of gravity z-axis multiplied by the weight mass is between about 2.5 g²·

mm² and about 72 g²·

mm².

2. The wood-type golf club head according to claim 1, wherein the golf club head moment of inertia about the head center of gravity z-axis multiplied by the weight mass is between about 2.5 g²·

mm² and about 3.6 g²·

mm².

3. The wood-type golf club head according to claim 1, wherein the golf club head moment of inertia about the head center of gravity z-axis multiplied by the weight mass is between about 3.6 g²·

mm² and about 18 g²·

mm².

4. The wood-type golf club head according to claim 1, wherein the golf club head moment of inertia about the head center of gravity z-axis multiplied by the weight mass is between about 18 g²·

mm² and about 72 g²·

mm².

5. The wood-type golf club head according to claim 1, wherein the at least one weight comprises two or more weights having a weights mass, and wherein the golf club head moment of inertia with two or more weights multiplied by the weights mass is between about 2.5 g²·

mm² and about 3.6 g²·

mm².

6. The wood-type golf club head according to claim 1, wherein the at least one weight comprises two or more weights having a weights mass, and wherein the golf club head moment of inertia with two or more weights multiplied by the weights mass is between about 3.6 g²·

mm² and about 18 g²·

mm².

7. The wood-type golf club head according to claim 1, wherein the at least one weight comprises two or more weights having a weights mass, and wherein the golf club head moment of inertia with two or more weights multiplied by the weights mass is between about 18 g²·

mm² and about 72 g²·

mm².

8. The wood-type golf club head according to claim 1, wherein the at least one weight comprises three or more weights having a weights mass, and wherein the golf club head moment of inertia with three or more weights multiplied by the weights mass is between about 2.5 g²·

mm² and about 3.6 g²·

mm².

9. The wood-type golf club head according to claim 1, wherein the at least one weight comprises three or more weights having a weights mass, and wherein the golf club head moment of inertia with three or more weights multiplied by the weights mass is between about 3.6 g²·

mm² and about 18 g²·

mm².

10. The wood-type golf club head according to claim 1, wherein the at least one weight comprises three or more weights having a weights mass, and wherein the golf club head moment of inertia with three or more weights multiplied by the weights mass is between about 18 g²·

mm² and about 72 g²·

mm².

11. The wood-type golf club head according to claim 1, wherein the at least one weight comprises four or more weights having a weights mass, and wherein the golf club head moment of inertia with four or more weights multiplied by the weights mass is between about 2.5 g²·

mm² and about 3.6 g²·

mm².

12. The wood-type golf club head according to claim 1, wherein the at least one weight comprises four or more weights having a weights mass, and wherein the golf club head moment of inertia with four or more weights multiplied by the weights mass is between about 3.6 g²·
