Abstract

A golf club head may include a body member having a ball striking face, a crown, a toe, a heel, a sole, a back, and a hosel region located at the intersection of the ball striking face, the heel, the crown and the sole. The crown may have a relatively round rear-side edge profile, as viewed from above. The sole may have a relatively square rear-side edge profile, as viewed from below. The rear-side edge of the sole may extend rearwardly beyond the rear-side edge of the crown along at least a portion of the back, as viewed from above. Further, the heel may have an airfoil-like surface in the forward portion of the heel. A golf club including the golf club head is also provided.

First claim

What is claimed is:

1. A golf club head for a metal wood type club, the golf club head comprising:
a body member having a ball striking face, a crown, a toe, a heel, a sole, a back and a hosel region located at an intersection of the ball striking face, the heel, the crown and the sole;
the crown having a relatively round rear-side edge profile, as viewed from above; and
the sole having a rear-side edge, wherein the rear-side edge has a relatively square profile as viewed from below, wherein the sole includes a toe-side corner and a heel-side corner, wherein the toe-side corner and the heel-side corner extend beyond the crown as viewed from above and the sole further includes a central portion of the rear-side edge of the sole that is covered by the crown as viewed from above.

2. The golf club head of claim 1 , wherein the club head includes a breadth that ranges from approximately 105 mm to approximately 125 mm.

3. The golf club head of claim 1 , wherein the club head includes a breadth that ranges from approximately 112 mm to approximately 116 mm.

4. The golf club head of claim 1 , wherein the club head includes a breadth that ranges from approximately 115 mm to approximately 118 mm.

5. The golf club head of claim 1 , wherein the crown includes a shortened hosel fairing that extends from the hosel region at an angle of from approximately 10 degrees to approximately 80 degrees from a moment-of-impact trajectory direction.

6. The golf club head of claim 1 , wherein the golf club head has a volume of 400 cc or greater and a club breadth-to-face length ratio of 0.90 or greater.

7. The golf club head of claim 1 , wherein the heel has an airfoil surface in a forward portion of the heel.

8. The golf club head of claim 1 , wherein a substantially U-shaped, concave groove is provided between the relatively round rear-side edge of the crown and the relatively square rear-side edge of the sole.

9. A golf club comprising:
a shaft; and the golf club head according to claim 1 , wherein the golf club head is secured to a first end of the shaft.

10. A golf club head for a metal wood type club, the golf club head having a volume of 400 cc or greater and a club breadth-to-face length ratio of 0.90 or greater, the golf club head comprising:
a body member having a ball striking face, a crown, a toe, a heel, a sole, a back, wherein the back includes a rearwardly tapered projection that extends from the heel to the toe along a lower portion of the back;
the sole having a rear-side edge, wherein the rear-side edge has a relatively square profile as viewed from below, and further wherein the rear-side edge of the sole rearwardly juts beyond the crown, forming a toe-side corner where the rearwardly tapered projection meets the toe and a heel-side corner where the rearwardly tapered projection meets the heel and furthermore the rearwardly tapered projection includes a central portion that is covered by the crown when viewed from above.

11. The golf club head of claim 10 , wherein the crown has a relatively round rear-side edge profile, as viewed from above.

12. The golf club head of claim 10 , wherein the club head includes a breadth that ranges from approximately 105 mm to approximately 125 mm.

13. The golf club head of claim 10 , wherein the back includes a substantially U-shaped, concave groove that extends across the entirety of the back.

14. The golf club head of claim 10 , further including a hosel region located at the intersection of the ball striking face, the heel, the crown and the sole and an elongated hosel fairing that extends from the hosel region at an angle of from approximately 10 degrees to approximately 80 degrees from a moment-of-impact trajectory direction.

15. A golf club comprising: a shaft; and the golf club head according to claim 10 , wherein the golf club head is secured to a first end of the shaft.

16. A golf club head for a metal wood type club, the club head comprising:
a body member having a ball striking face, a crown, a toe, a heel, a sole, a back, wherein the back includes a rearwardly tapered projection that extends from the heel to the toe along a lower portion of the back;
the crown having a relatively round rear-side edge profile, as viewed from above,
the sole having a relatively square rear-side edge profile as viewed from below,
wherein the rearwardly tapered projection includes a toe-side corner and a heel-side corner that extend rearwardly beyond the crown when viewed from above and a central portion of the rearwardly tapered projection that is covered by the crown when viewed from above.

17. The golf club head of claim 16 , wherein the club head includes a breadth that ranges from approximately 105 mm to approximately 125 mm.

18. The golf club head of claim 16 , wherein the club head includes a breadth that ranges from approximately 112 mm to approximately 116 mm.

19. The golf club head of claim 16 , wherein the club head includes a breadth that ranges from approximately 115 mm to approximately 118 mm.

20. The golf club head of claim 16 , wherein the golf club head has a volume of 400 cc or greater and a club breadth-to-face length ratio of 0.90 or greater.

21. The golf club head of claim 16 , wherein the heel has an airfoil surface in a forward portion of the heel.

22. The golf club head of claim 16 , wherein a substantially U-shaped, concave groove is provided between the relatively round rear-side edge of the crown and the relatively square rear-side edge of the sole.

23. A golf club comprising:
a shaft; and the golf club head according to claim 16 , wherein the golf club head is secured to a first end of the shaft.
