Abstract

A golf club head comprises a body and at least one self-extracting pressed weight assembly. The body comprises 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. The body defines an interior cavity. The weight assembly comprises at least three components and is configured for a press fit engagement with the golf club head. The assembly has a drive portion and a threaded portion.

First claim

The invention claimed is:

one or more recesses for receiving and retaining one or more removable weights;
the one or more removable weights configured to substantially conform to the one or more recesses of the club head, the one or more removable weights ranging from about 1 gram to about 25 grams, wherein the one or more removable weights comprises (a) a head for receiving an engagement end of a tool, and (b) a body extending from the head and configured to cooperatively engage the one or more recesses;
wherein the one or more recesses have a combined volume between about 0.3 cm 3 and about 15 cm 3 ;
wherein at least one of the one or more removable weights has a head origin x-axis coordinate between about −10 mm and about 10 mm, and a head origin y-axis coordinate greater than about 50 mm;
wherein the golf club head has a golf club head center of gravity with a CG head origin z-axis coordinate less than about 0 mm, a CG head origin y-axis coordinate less than about 50 mm, and a CG head origin x-axis coordinate greater than about −10 mm and less than about 10 mm;
wherein the golf club head has a face with a face thickness that varies;
wherein the golf club head has a coefficient of restitution greater than about 0.8 and less than 1.0; and
wherein the golf club head has a volume between about 250 cm 3 and about 500 cm 3 , a moment of inertia about a head center of gravity z-axis (Izz), and a moment of inertia about a head center of gravity x-axis (Ixx), and a summation of Izz and Ixx is between about 740 kg·mm 2 about 1000 kg·mm 2 .

2. The golf club head of claim 1 , wherein the golf club head has a crown areal weight less than about 0.35 g/cm 2 over more than about 50% of the crown surface area, and the crown is formed from a metal alloy.

3. The golf club head of claim 1 , wherein the golf club head has a sole areal weight less than about 0.35 g/cm 2 over more than about 50% of the sole surface area.

4. The golf club head of claim 1 , wherein at least a portion of the golf club head is formed of a non-metallic composite material having a composite portion areal weight of less than about 0.35 g/cm 2 .

5. The golf club head of claim 4 , wherein the non-metallic composite portion of the golf club head includes at least a portion of a crown, and more than about 50% of the crown surface area is formed of the non-metallic composite material.

6. The golf club head of claim 4 , wherein the non-metallic composite portion of the club head includes at least a portion of a sole and has a composite sole portion areal weight of less than about 0.35 g/cm 2 .

7. The golf club head of claim 1 , wherein the thickness of a portion of the face is greater than about 3.0 mm, and the CG head origin z-axis coordinate is less than about −2 mm.

8. The golf club head of claim 1 , wherein the thickness of a portion of the face is less than about 2.3 mm, and the CG head origin z-axis coordinate is less than about −2 mm.

9. The golf club head of claim 1 , wherein the one or more recesses for receiving the one or more removable weights includes two or more recesses for receiving two or more removable weights including at least a first weight having a first mass and a second weight having a second mass, and the first mass is at least three times the second mass; and
wherein the two or more recesses have a combined volume between about 0.3 cm 3 and about 15 cm 3 .

10. The golf club head of claim 9 , wherein at least one of the two or more removable weights has a head origin y-axis coordinate greater than about 20 mm and less than about 50 mm.

11. The golf club head of claim 10 , wherein the first mass is between about 1 gram and about 3 grams, and the second mass is between about 6 gram and about 18 grams.

12. A golf club head comprising:
one or more recesses for receiving and retaining one or more removable weights;
the one or more removable weights configured to substantially conform to the one or more recesses of the club head, the one or more removable weights ranging from about 1 gram to about 25 grams, wherein the one or more removable weights comprises (a) a head for receiving an engagement end of a tool, and (b) a body extending from the head and configured to cooperatively engage the one or more recesses;
wherein the one or more recesses have a combined volume between about 0.3 cm 3 and about 15 cm 3 ;
wherein at least one of the one or more removable weights has a head origin x-axis coordinate between about −10 mm and about 10 mm, and a head origin y-axis coordinate greater than about 50 mm;
wherein the golf club head has a golf club head center of gravity with a CG head origin z-axis coordinate less than about 0 mm, a CG head origin y-axis coordinate less than about 50 mm, and a CG head origin x-axis coordinate greater than about −10 mm and less than about 10 mm;
wherein the golf club head has a face with a face thickness that varies;
wherein the golf club head has a coefficient of restitution greater than about 0.8 and less than 1.0; and
wherein the golf club head has a volume between about 250 cm 3 and about 500 cm 3 , a moment of inertia about a head center of gravity z-axis (Izz) between about 250 kg·mm 2 and about 600 kg·mm 2 , and a moment of inertia about a head center of gravity x-axis (Ixx) between about 140 kg·mm 2 and about 400 kg·mm 2 .

13. The golf club head of claim 12 , wherein the golf club head has a crown areal weight less than about 0.35 g/cm 2 over more than about 50% of the crown surface area.

14. The golf club head of claim 12 , wherein at least a portion of the crown is formed of a non-metallic composite material.
