Abstract

A golf club includes a shaft and a club head. The club head includes a body member having a ball striking face, a heel, a toe, a back, a crown, a sole, and a hosel region located at the intersection of the ball striking face, the heel and the crown. The sole includes a channel extending from the hosel region toward the toe. An insert is received within the channel. The club head further includes means for detachably securing the insert to the channel. A second insert configured for being received within the channel may be provided.

Claims

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 extending rearward from the ball striking face, a sole extending rearward from the ball striking face opposite the crown, a heel, a toe opposite the heel, and a hosel region located at an intersection of the ball striking face, the heel and the crown;

the sole including a channel extending from the hosel region toward the toe, wherein the channel includes a heel portion and a toe portion, and

an insert received within the channel, wherein the insert has an exposed surface that is recessed with respect to an outer surface of the sole adjacent the channel between a front edge of the channel and the ball striking face.

2. The golf club head for a metal wood type club of claim 1, wherein the channel is located in a forward region of the golf club head, wherein the forward region of the golf club head is a forward 30% of a breadth defined in a front-to-rear direction of the golf club head.

3. The golf club head for a metal wood type club of claim 1, wherein a toe side edge of the channel is located within a range of 65% to 100% of a length of the golf club head in a heel-to-toe direction.

4. The golf club head for a metal wood type club of claim 1, wherein the channel has a maximum width in a front-to-rear direction of the golf club head of less than or equal to 25 mm.

5. The golf club head for a metal wood type club of claim 1, wherein the front edge of the channel is parallel to a portion of a rear edge of the channel.

6. The golf club head for a metal wood type club of claim 1, wherein a width of the channel defined in a front-to-rear direction varies along a length of the channel defined in a heel-to-toe direction.

7. The golf club head for a metal wood type club of claim 1, wherein the insert has a thickness, defined in a sole-to-crown direction, that decreases as the insert extends away from the hosel region.

8. The golf club head for a metal wood type club of claim 1, wherein the insert includes a groove in the exposed surface.

9. 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 extending rearward from the ball striking face, a sole extending rearward from the ball striking face opposite the crown, a heel, a toe opposite the heel, and a hosel region located at an intersection of the ball striking face, the heel and the crown;

the sole including a channel extending from the hosel region toward the toe of the body member, wherein the channel has an elongated shape with a length defined in a heel-to-toe direction being greater than a width defined in a front-to-rear direction and extending across a centerline of the golf club head, and wherein the channel comprises a hosel-side edge, a toe-side edge, a first sidewall extending between the hosel-side edge and the toe-side edge, and a second sidewall extending between the hosel-side edge and the toe-side edge; and

an insert located within the channel, wherein the insert has a thickness less than a depth of the channel thereby forming a recess in the sole.

10. The golf club head for a metal wood type club claim 9, wherein the channel is located in a forward region of the golf club head, and wherein the forward region of the golf club head is a forward 30% of a breadth defined in a front-to-rear direction of the golf club head.

11. The golf club head for a metal wood type club of claim 9, wherein the channel is located in a forward region of the golf club head, and wherein the forward region of the golf club head is a forward 20% of a breadth defined in a front-to-rear direction of the golf club head.

12. The golf club head for a metal wood type club of claim 9, wherein the insert includes one or more grooves.

13. The golf club head of claim 9, wherein the recess extends along a majority of the length of the channel.

14. The golf club head of claim 9, wherein the channel has a maximum width of the golf club head of less than or equal to 25 mm.

15. The golf club head for a metal wood type club of claim 9, wherein the first sidewall of the channel is parallel to the second sidewall of the channel.

16. A golf club head for a metal wood type club, the golf club head comprising:

a body member having a ball striking face, a heel, a toe, a back, a crown, a sole, and a hosel region located at an intersection of the ball striking face, the heel, and the crown;

wherein the sole includes a channel extending from the hosel region toward the toe and includes;

a hosel-side edge extending in a front-to-rear direction, a toe-side edge extending in the front-to-rear direction, a first sidewall extending between the hosel-side edge and the toe-side edge, and a second sidewall extending between the hosel-side edge and the toe-side edge, wherein the first sidewall of the channel is parallel to the second sidewall of the channel,

wherein the channel is located in a forward region of the golf club head, wherein the forward region of the golf club head is a forward 30% of a breadth of the golf club head; and

an insert located within the channel, the insert including an exposed surface, wherein a portion of the exposed surface of the insert is recessed with respect to an outer surface of the sole.

17. The golf club head of claim 16, wherein the channel has a maximum width in the front-to-rear direction of the golf club head of less than or equal to 25 mm.

18. The golf club head for a metal wood type club of claim 16, wherein the exposed surface of the insert includes a groove.

19. The golf club head for a metal wood type club of claim 16, wherein the channel is substantially trapezoidally-shaped.

20. The golf club head for a metal wood type club of claim 16, wherein the insert comprises at least one protrusion, and the channel comprises at least one notch, and wherein the at least one protrusion is received into the at least one notch of the channel.
