Abstract

A golf club head includes a striking face having a face center and a virtual striking face plane generally parallel to the striking face. The golf club head further includes a sole portion, a top portion, a rear portion, and a loft L no less than 40°. A virtual vertical plane perpendicular to the striking face plane passes through the face center. A club head center of gravity is spaced from the virtual vertical plane in the heel-to-toe direction by a distance D1 that is no greater than 6.0 mm. The golf club head further includes a hosel including an internal bore configured to receive a golf shaft. The internal bore includes a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf club shaft. The hosel further comprises an auxiliary recess extending sole-ward from the abutment surface of the internal bore.

First claim

We claim:

1. A golf club head that, when oriented in a reference position, comprises:
a striking face having a face center, a leading edge, and a virtual striking face plane generally parallel to the striking face;
a sole portion having a sole width D 8 that is between 14 mm and 20 mm;
a top portion;
a rear portion;
a loft L no less than 40°;
a virtual vertical plane perpendicular to the 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 no greater than 6.0 mm; and
a hosel comprising a virtual hosel axis and an internal bore configured to receive a golf club 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 (i) extending sole-ward from the abutment surface of the internal bore and (ii) tapering in width in a sole-ward direction,
wherein the club head comprises a blade-type golf club head comprising an upper blade portion having a substantially uniform thickness and a lower muscle portion.

2. The golf club head of claim 1 , wherein the auxiliary recess comprises a depth, measured in a direction of the hosel axis, of no less than 5 mm.

3. The golf club head of claim 1 , wherein the distance D 1 is no greater than 5.0 mm.

4. The golf club head of claim 1 , further comprising a point P 1 located at an intersection of the leading edge and the virtual vertical plane, wherein the center of gravity is vertically spaced from the point P 1 by a distance D 3 such that: D 3 ≥29.5 mm)−(0.3 mm/°)×L.

5. The golf club head of claim 1 , wherein the auxiliary recess is at least partially filled.

6. The golf club head of claim 1 , wherein the hosel has a hosel upper end, and a distance D 4 , measured from the hosel upper end to a virtual ground plane along the virtual hosel axis, is no greater than 75 mm.

7. The golf club head of claim 1 , further comprising a maximum top line thickness D 5 no greater than 5.70 mm.

8. A golf club head that, when oriented in a reference position, comprises:
a striking face having a face center, a leading edge, and a virtual striking face plane generally parallel to the striking face;
a sole portion;
a top portion;
a rear portion;
a loft L no less than 40°;
a virtual vertical plane perpendicular to the 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 no greater than 6.0 mm;
a hosel comprising a virtual hosel axis and an internal bore configured to receive a golf club 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; and
a point P 1 located at an intersection of the leading edge and the virtual vertical plane, wherein the center of gravity is vertically spaced from the point P 1 by a distance D 3 that is no greater than 17 mm,
wherein the club head comprises a blade-type golf club head comprising an upper blade portion having a substantially uniform thickness and a lower muscle portion.

9. The golf club head of claim 8 , wherein the sole portion further comprises a sole width D 8 that is between 14 mm and 20 mm.

10. The golf club head of claim 8 , wherein the auxiliary recess comprises a depth, measured in a direction of the hosel axis, of no less than 5 mm.

11. The golf club head of claim 8 , wherein the distance D 1 is no greater than 5.0 mm.

12. The golf club head of claim 8 , wherein: D3≥29.5 mm)−(0.3 mm/°)×L.

13. The golf club head of claim 8 , wherein:
the hosel has a hosel upper end; and
a distance D 4 , measured from the hosel upper end to a virtual ground plane along the virtual hosel axis, is no greater than 75 mm.

14. The golf club head of claim 8 , further comprising a maximum top line thickness D 5 no greater than 5.70 mm.

15. A golf club head that, when oriented in a reference position, comprises:
a striking face having a face center, a leading edge, and a virtual striking face plane generally parallel to the striking face;
a sole portion;
a top portion;
a rear portion;
a loft L no less than 40°;
a virtual vertical plane perpendicular to the 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 no greater than 6.0 mm; and
a hosel comprising a virtual hosel axis and an internal bore configured to receive a golf club 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, the auxiliary recess tapering in width in a sole-ward direction,
wherein the club head comprises a blade-type golf club head comprising an upper blade portion having a substantially uniform thickness and a lower muscle portion.

16. The golf club head of claim 15 , wherein the auxiliary recess comprises a depth, measured in a direction of the hosel axis, of no less than 5 mm.

17. The golf club head of claim 15 , wherein the distance D 1 is no greater than 5.0 mm.

18. The golf club head of claim 15 , further comprising a point P 1 located at an intersection of the leading edge and the virtual vertical plane, wherein the center of gravity is vertically spaced from the point P 1 by a distance D 3 such that: D3≥29.5 mm)−(0.3 mm/°)×L,
