Abstract

An exemplary golf club head having an increased amount of discretionary mass may be realized by utilizing improved drop angles, an improved average crown height, and/or articulation points. The discretionary mass may be placed low and deep in the club head to improve the location of the center of gravity as well as the inertial properties. A preferred break length may also be utilized to further improve the depth of the center of gravity. In one example, the center of gravity may be positioned to substantially align the sweet spot with the face center of the club head.

First claim

The invention claimed is:

1. A golf club head comprising:
a volume no less than 200 cm 3 ;
a top portion;
a rear portion having an outer surface;
a strike face comprising an outer surface, a top edge, a face center, and a center apex, wherein the center apex is a point of intersection between an imaginary vertical traversing plane, oriented substantially perpendicular to the strike face and passing through the face center, and the top edge of the strike face, the golf club head having a rearmost point specific to the imaginary vertical traversing plane;
a hosel having a hosel centerline, wherein the club golf head is oriented relative to an imaginary horizontal ground plane so that the hosel centerline is in an imaginary vertical hosel plane generally parallel to the top edge of the strike face, the hosel centerline oriented at an angle of 60° relative to the imaginary horizontal ground plane;
a first imaginary vertical line extending from the center apex to the imaginary horizontal ground plane; and
a first horizontal distance, in a direction perpendicular to the imaginary vertical hosel plane, between the first imaginary vertical line and the outer surface of the rear portion of the golf club head, the first horizontal distance being measured at a height between about 1 mm and about 15 mm relative to the imaginary horizontal ground plane and vertically spaced from a rear-most point of the club head, the first horizontal distance being between about 90 mm and about 110 mm.

2. The golf club head of claim 1 further comprising:
a center of gravity; and
wherein a point of intersection between the outer surface of the strike face and an imaginary line perpendicular to the strike face and passing through the center of gravity of the golf club head is substantially coincident with the face center.

3. The golf club head of claim 1 , wherein the strike face further comprises a face height between about 43 mm and about 61 mm.

4. The golf club head of claim 3 , wherein the strike face further comprises a face length between about 94 mm and about 115 mm.

5. The golf club head of claim 4 , wherein the center of gravity located a third horizontal distance between about 12 mm and about 38 mm from the imaginary vertical hosel plane.

6. The golf club head of claim 5 , wherein the center of gravity is located a vertical distance between about 20 mm and about 33 mm from the imaginary horizontal ground plane.

7. The golf club head of claim 1 further comprising an imaginary coordinate system having an origin located at the center of gravity of the golf club head, the coordinate system having an x-axis, a y-axis, and a z-axis, wherein the golf club head has a moment of inertia of at least about 3700 gcm2 about the z-axis.

8. The golf club head of claim 7 , wherein the golf club head has a moment of inertia of at least about 2300 g*cm 2 about the y-axis.

9. The golf club head of claim 8 , wherein the center of gravity is located a third horizontal distance between about 12 mm and about 38 mm from the imaginary vertical hosel plane.

10. The golf club head of claim 9 , wherein the center of gravity is located a vertical distance between about 20 mm and about 33 mm from the imaginary horizontal ground plane.

11. A wood-type golf club head comprising:
a top portion;
a rear portion having an outer surface;
a strike face comprising an outer surface, a top edge, a face center, and a center apex, wherein the center apex is a point of intersection between an imaginary vertical traversing plane, oriented substantially perpendicular to the strike face and passing through the face center, and the top edge of the strike face, the golf club head having a rearmost point specific to the imaginary vertical traversing plane;
a hosel having a hosel centerline, wherein the club golf head is oriented relative to an imaginary horizontal ground plane so that the hosel centerline is in an imaginary vertical hosel plane generally parallel to the top edge of the strike face, the hosel centerline oriented at an angle of 60° relative to the imaginary horizontal ground plane;
a first imaginary vertical line extending from the center apex to the imaginary horizontal ground plane; and
a first horizontal distance, in a direction perpendicular to the imaginary vertical hosel plane, between the first imaginary vertical line and the outer surface of the rear portion of the golf club head, the first horizontal distance being measured at a height between about 1 mm and about 15 mm relative to the imaginary horizontal ground plane and vertically spaced from a rear-most point of the club head, the first horizontal distance being between about 90 mm and about 110 mm.

12. The golf club head of claim 11 further comprising:
a center of gravity; and
wherein a point of intersection between the outer surface of the strike face and an imaginary line perpendicular to the strike face and passing through the center of gravity of the golf club head is substantially coincident with the face center.

13. The golf club head of claim 11 , wherein the strike face further comprises a face height between about 43 mm and about 61 mm.

14. The golf club head of claim 13 , wherein the strike face further comprises a face length between about 94 mm and about 115 mm.

15. The golf club head of claim 14 , wherein the center of gravity located a third horizontal distance between about 12 mm and about 38 mm from the imaginary vertical hosel plane.

16. The golf club head of claim 15 , wherein the center of gravity is located a vertical distance between about 20 mm and about 33 mm from the imaginary horizontal ground plane.

17. The golf club head of claim 11 further comprising an imaginary coordinate system having an origin located at the center of gravity of the golf club head, the coordinate system having an x-axis, a y-axis, and a z-axis, wherein the golf club head has a moment of inertia of at least about 3700 gcm2 about the z-axis.

18. The golf club head of claim 17 , wherein the golf club head has a moment of inertia of at least about 2300 g*cm 2 about the y-axis.

19. The golf club head of claim 18 , wherein the center of gravity is located a third horizontal distance between about 12 mm and about 38 mm from the imaginary vertical hosel plane.

20. The golf club head of claim 19 , wherein the center of gravity is located a vertical distance between about 20 mm and about 33 mm from the imaginary horizontal ground plane.
