Abstract

A golf club head includes a striking face, a sole portion, a top portion, a hosel, a rear surface, a loft no less than 40°, a virtual vertical plane, and a center of gravity. The striking face has a face center, a leading edge, and a virtual striking face plane. The hosel includes an internal bore configured to receive a golf shaft and includes a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf shaft. The rear surface is opposite the striking face and has an upper portion and a lower portion, the lower portion including a forward-extending recess. The insert covers the recess forming a hollow portion. The virtual vertical plane is perpendicular to the striking face plane and passes through the face center. The center of gravity is spaced a distance from the virtual vertical plane in the heel-to-toe direction.

First claim

We claim:

1. A golf club head that, when oriented in a reference position, comprises:
a striking face having a face center and a leading edge;
a sole portion;
a top portion;
a rear portion;
a loft L no less than 40°;
a virtual vertical plane perpendicular to a striking face plane and passing through the face center;
a club head center of gravity spaced from the virtual vertical plane in a heel-to-toe direction by a distance D 1 that is equal to or less than (0.08 mm/°)*L; and
a hosel comprising a virtual hosel axis and an internal bore configured to receive a golf shaft, the internal bore including a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf club shaft, the hosel further comprising an auxiliary recess extending sole-ward from the abutment surface of the internal bore, wherein the auxiliary recess comprises a width between 4 mm and 10 mm.

2. The golf club head of claim 1 , wherein the internal bore comprises a depth that is no greater than 30 mm.

3. The golf club head of claim 1 , wherein the auxiliary recess comprises a depth between 4 mm and 7 mm.

4. The golf club head of claim 1 , wherein the width of the auxiliary recess tapers in a sole-ward direction along the virtual hosel axis.

5. The golf club head of claim 1 , wherein the auxiliary recess is at least partially filled with a material having a density less than a density of the hosel.

6. The golf club of claim 1 , wherein D 1 is equal to or less than (0.075 mm/°)*L.

7. The golf club of claim 1 , wherein D 1 is equal to or less than (0.065 mm/°)*L.

8. The golf club of claim 1 , further comprising a bounce angle θ measured in the virtual vertical plane, no less than 4°.

9. The golf club of claim 1 , further comprising a sole taper angle in the heel-to-toe direction no less than 0.10 times loft (0.10*L).

10. A golf club head that, when oriented in a reference position, comprises:
a striking face having a face center and a leading edge;
a sole portion;
a top portion;
a rear portion;
a loft L no less than 40°; and
a hosel comprising a virtual hosel axis and an internal bore configured to receive a golf shaft, the internal bore including a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf club shaft, the internal bore comprising a depth no greater than 30 mm, and the hosel further comprising an auxiliary recess extending sole-ward from the abutment surface of the internal bore, the auxiliary recess including a depth between 4 mm and 7 mm.

11. The golf club head of claim 10 , further comprising:
a virtual vertical plane perpendicular to a striking face plane and passing through the face center; and
a club head center of gravity spaced from the virtual vertical plane in a heel-to-toe direction by a distance D 1 that is equal to or less than (0.08 mm/°)*L.

12. The golf club head of claim 11 , wherein D 1 is equal to or less than (0.075 mm/°)*L.

13. The golf club head of claim 11 , wherein D 1 is equal to or less than (0.065 mm/°)*L.

14. The golf club head of claim 10 , wherein the auxiliary recess comprises a width between 4 mm and 10 mm.

15. The golf club head of claim 14 , wherein the width of the auxiliary recess tapers in a sole-ward direction along the virtual hosel axis.

16. The golf club head of claim 10 , wherein the auxiliary recess is at least partially filled with a material having a density less than a density of the hosel.

17. The golf club head of claim 16 , wherein the material includes a density no greater than 7 g/cm 3 .

18. The golf club head of claim 16 , wherein the material includes a density no greater than 4 g/cm 3 .

19. The golf club head of claim 10 , further comprising a sole taper angle in the heel-to-toe direction no less than 0.10 times loft (0.10*L).

20. The golf club head of claim 10 , further comprising a bounce angle θ measured in the virtual vertical plane, no less than 4°.
