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 lace 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 all interior cavity;

two or more weight ports formed in the body; and

at least one weight configured to be retained at least partially within one of the weight ports;

wherein the head includes a golf club head origin positioned on the face plate at a geometric center of the face plate, the head origin including an x-axis tangential to the face plate and generally parallel to the ground when the head is ideally positioned, and

wherein the head includes a golf club head center of gravity having an x-axis generally parallel to the origin x-axis, and wherein a golf club head moment of inertia about the head center of gravity x-axis divided by the golf club head mass without the at least one weight is between about 800 mm² and about 4,000 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 x-axis divided by the mass of the golf club head without the at least one weight is between about 800 mm² and about 1,100 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 x-axis divided by the mass of the golf club head without the at least one weight is between about 1,100 mm² and about 1,600 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 x-axis divided by the mass of the golf club head without the at least one weight is between about 1,600 mm² and about 4,000 mm².

5. The wood-type golf club head according to claim 1, wherein the at least one weight comprises two or more weights, and wherein the golf club head moment of inertia divided by the mass of the golf club head without the two or more weights is between about 800 mm² and about 1,100 mm².

6. The wood-type golf club head according to claim 1, wherein the at least one weight comprises two or more weights, and wherein the golf club head moment of inertia divided by the mass of the golf club head without the two or more weights is between about 1,100 mm² and about 1,600 mm².

7. The wood-type golf club head according to claim 1, wherein the at least one weight comprises two or more weights, and wherein the golf club head moment of inertia divided by the mass of the golf club head without the two or more weights is between about 1,600 mm² and about 4,000 mm².

8. The wood-type golf club head according to claim 1, wherein the at least one weight comprises three or more weights, and wherein the golf club head moment of inertia divided by the mass of the golf club head without the three or more weights is between about 800 mm² and about 1,100 mm².

9. The wood-type golf club head according to claim 1, wherein the at least one weight comprises three or more weights, and wherein the golf club head moment of inertia divided by the mass of the golf club head without the three or more weights is between about 1,100 mm² and about 1,600 mm².

10. The wood-type golf club head according to claim 1, wherein the at least one weight comprises three or more weights, and wherein the golf club head moment of inertia divided by the mass of the golf club head without the three or more weights is between about 1,600 mm² and about 4,000 mm².

11. The wood-type golf club head according to claim 1, wherein the at least one weight comprises four or more weights and wherein the golf club head moment of inertia divided by the mass of the golf club head without the four or more weights is between about 800 mm² and about 1,100 mm².

12. The wood-type golf club head according to claim 1, wherein the at least one weight comprises four or more weights and wherein the golf club head moment of inertia divided by the mass of the golf club head without the four or more weights is between about 1,100 mm² and about 1,600 mm².

13. The wood-type golf club head according to claim 1, wherein the at least one weight comprises four or more weights, and wherein the golf club head moment of inertia divided by the mass of the golf club head without the four or more weights is between about 1,600 mm² and about 4,000 mm².
