Abstract

A golf club head is presented comprising a sole including a removable panel secured to the sole via a non-threaded attachment assembly. Further, the removable panel may have a large surface area relative to its thickness, resulting in a chip-like or wafer-like weight member. This design allows the mass of the removable panel to be spread substantially along the surface of the sole as opposed to in the interior of the club head. The golf club head may comprise more than one removable panel. A removable panel of the present invention may generally comprise one or more discrete areas of higher basis weight or higher density. Even further, the removable panel may generally be releasably attached via a quick disconnect mechanism that allows easy interchangeability.

Claims

1. A golf club head comprising:

a hosel, a face, a crown, and a sole;

wherein said sole further comprises one or more removable panels releasably attached to said sole, and

wherein said hosel further comprises a shaft adjustment mechanism to adjust a shaft angle of said golf club head;

said shaft adjustment mechanism further comprises;

a sleeve adapted to connect to a distal end of a shaft via a shaft bore;

a plurality of shaft slots, located within a hosel bore, each allowing said sleeve to be connected to said golf club head at a different orientation; and

a plurality of separators, interposed between said plurality of shaft slots, securing said sleeve to said club head,

wherein an angular attribute of a longitudinal axis of said shaft bore is offset from an angular attribute of a longitudinal axis of said sleeve; and

wherein said one or more removable panels comprises a first material having a first density, and said first density is greater than a second density of a second material, used to form the remainder of said sole.

2. The golf club head of claim 1, wherein a location of said removable panel is placed near a heel portion of said sole.

3. The golf club head of claim 1, wherein a location of said removable panel is placed near a toe portion of said sole.

4. The golf club head of claim 1, wherein a location of said removable panel is placed near a back portion of said sole.

5. The golf club head of claim 1, wherein said plurality of shaft slots is arranged in a linear fashion in a front to back direction.

6. The golf club head of claim 1, wherein said shaft adjustment mechanism is a toothed joint.

7. The golf club head of claim 1, wherein said shaft adjustment mechanism is a circular joint.

8. A golf club head comprising:

a hosel, a face, a crown, and a sole;

wherein said sole further comprises one or more removable panels releasably attached to said sole, and

said shaft adjustment mechanism further comprises;

a sleeve adapted to connect to a distal end of a shaft via a shaft bore;

wherein an angular attribute of a longitudinal axis of said shaft bore is offset from an angular attribute of a longitudinal axis of said sleeve; and

wherein said one or more removable panels comprises a first material having a first density, and said first density is greater than a second density of a second material, used to form the remainder of said sole.

9. The golf club head of claim 8, wherein a location of said removable panel is placed near a heel portion of said sole.

10. The golf club head of claim 8, wherein a location of said removable panel is placed near a toe portion of said sole.

11. The golf club head of claim 8, wherein a location of said removable panel is placed near a back portion of said sole.

12. The golf club head of claim 8, wherein said one or more removable panels are connected to said sole utilizing a quick disconnect mechanism.

13. The golf club head of claim 8, further comprising a vibration dampening layer interposed between said removable panel and said sole.

14. The golf club head of claim 8, wherein said removable panel is connected to said sole utilizing a quick disconnect mechanism.

15. The golf club head of claim 14, wherein said quick disconnect mechanism further comprises;

a bore shaft protruding from said sole of said golf club head;

a plurality of teeth providing a male component between said sole and said removable panel; and

a score line providing a female component between said sole and said removable panel;

wherein said plurality of teeth and said score line engages one another to resist withdrawal of said removable panel from said golf club head.

16. The golf club head of claim 15, wherein said plurality of teeth is angularly disposed with respect to said bore shaft.

17. A golf club head comprising:

a hosel, a face, a crown, and a sole;

wherein said sole further comprises one or more removable panels releasably attached to said sole, and

wherein said hosel further comprises a shaft adjustment mechanism to adjust a shaft angle of said golf club head;

said shaft adjustment mechanism further comprises;

a sleeve adapted to connect to a distal end of a shaft via a shaft bore;

a plurality of shaft slots, located within a hosel bore, each allowing said sleeve to be connected to said golf club head at a different orientation; and

a plurality of separators, interposed between said plurality of shaft slots, securing said sleeve of said shaft to said club head,

wherein an angular attribute of a longitudinal axis of said shaft bore is offset from an angular attribute of a longitudinal axis of said sleeve.

18. The golf club head of claim 17, wherein said removable panel is connected to said sole utilizing a quick disconnect mechanism.

19. The golf club head of claim 18, wherein said quick disconnect mechanism further comprises;

a bore shaft protruding from said sole of said golf club head;

a plurality of teeth providing a male component between said sole and said removable panel; and

a score line providing a female component between said sole and said removable panel;

wherein said plurality of teeth and said score line engages one another to resist withdrawal of said removable panel from said golf club head.
