Abstract

Aspects of this invention relate to structures and methods for connecting golf club heads to shafts in a releasable and adjustable manner allowing independent adjustability of face angle, loft angle, and lie angle of a club head. Assemblies for connecting the club head and shaft may include: (a) a hosel assembly; (b) an adjustment member; and (c) a securing system for releasably and adjustably securing the hosel assembly and adjustment member to the club head. The face angle, loft angle, and lie angle may be independently adjusted by releasing the securing system and rotating the different structures or exchanging the original parts with different parts.

First claim

We claim:

1. A golf club, comprising:
a shaft;
a golf club head that includes a hosel opening that provides access to a club head chamber defined in the club head, wherein the hosel opening is located below a crown surface of the golf club head;
a hosel assembly including a first end and a second end opposite the first end, the first end including an open first end that defines an interior chamber for receiving the shaft, and the second end including an outer surface that defines a rotation inhibiting structure;
an adjustment member that defines an exterior surface with an exterior rotation-inhibiting structure and an interior surface with an interior rotation-inhibiting structure, wherein the interior rotation inhibiting structure cooperatively engages with the rotation-inhibiting structure on the hosel assembly, and further wherein changing the rotational position of the adjustment member with respect to the hosel assembly provides independent adjustment of a face angle of the golf club head;
one or more sleeve inserts configured to adjust the location of the hosel assembly within a club head chamber, thereby providing independent adjustment of a lie angle of a golf club head, wherein the sleeve inserts include an exterior portion generally cylindrical in shape and fitting into and engaging the interior of the club head chamber, and further includes an interior portion generally cylindrical in shape and accepting and engaging the hosel assembly directly and the adjustment member directly, and wherein the one or more sleeve inserts are non-rotational with respect to the hosel assembly and the adjustment member; and
a securing system for releasably securing the adjustment member and one of the one or more sleeve inserts with the hosel assembly.

2. A golf club according to claim 1 , wherein the second end of the hosel assembly includes an inner surface that engages a securing member of the securing system.

3. A golf club according to claim 2 , wherein the inner surface includes threads to engage to threads on the securing member.

4. A golf club according to claim 1 , wherein the hosel assembly further includes an expanded portion that provides a stop that prevents the hosel assembly from extending into a golf club head and provides a strong base for securing the hosel assembly.

5. A golf club according to claim 1 , wherein the second end of the hosel assembly is tapered to provide a smooth transition between the hosel assembly and a golf club head.

6. A golf club according to claim 1 , wherein the adjustment member defines an opening sized such that a securing member of the securing system is able to freely pass through the opening to engage the hosel assembly.

7. A golf club according to claim 1 , wherein the exterior rotation-inhibiting structure is defined by an exterior tooth extending along the longitudinal axis of the exterior surface of the adjustment member.

8. A golf club according to claim 1 , wherein the interior rotation-inhibiting structure is defined by an interior tooth extending along the longitudinal axis of the interior surface of the adjustment member.

9. A golf club, comprising:
a shaft;
a golf club head that includes a hosel opening that provides access to a club head chamber defined in the club head, wherein the hosel opening is located below a crown surface of the golf club head;
a hosel assembly including a first end and a second end opposite the first end, the first end including an open first end that defines an interior chamber for receiving the shaft and located below the crown surface of the golf club head, and the second end including an outer surface that defines a rotation inhibiting structure, wherein the hosel assembly engages the hosel opening;
an adjustment member that defines an exterior surface with an exterior rotation-inhibiting structure, and an interior surface with an interior rotation-inhibiting structure, wherein the interior rotation inhibiting structure cooperatively engages with the rotation-inhibiting structure on the hosel assembly, and further wherein changing the rotational position of the adjustment member with respect to the hosel assembly provides independent adjustment of a face angle of the golf club head;
one or more sleeve inserts providing independent adjustment of a lie angle of the golf club head, wherein the sleeve inserts include an exterior portion generally cylindrical in shape and fitting into and engaging the interior of the club head chamber, and further includes an interior portion generally cylindrical in shape and accepting and engaging the hosel assembly directly and the adjustment member directly, and wherein the one or more sleeve inserts are non-rotational with respect to the hosel assembly and the adjustment member; and
a securing system for releasably securing the adjustment member and one of the one or more sleeve inserts with the hosel assembly.

10. A golf club according to claim 9 , wherein the second end of the hosel assembly includes an inner surface that engages a securing member of the securing system.

11. A golf club according to claim 10 , wherein the inner surface includes threads to engage to threads on the securing member.

12. A golf club according to claim 9 , wherein the hosel assembly further includes an expanded portion that provides a stop that prevents the hosel assembly from extending into the golf club head and provides a strong base for securing the hosel assembly.

13. A golf club according to claim 9 , wherein the second end of the hosel assembly is tapered to provide a smooth transition between the hosel assembly and the golf club head.

14. A golf club according to claim 9 , wherein the adjustment member defines an opening sized such that a securing member of the securing system is able to freely pass through the opening to engage the hosel assembly.

15. A golf club according to claim 9 , wherein the exterior rotation-inhibiting structure is defined by an exterior tooth extending along the longitudinal axis of the exterior surface of the adjustment member.

16. A golf club according to claim 9 , wherein the interior rotation-inhibiting structure is defined by an interior tooth extending along the longitudinal axis of the interior surface of the adjustment member.

17. A golf club according to claim 9 , wherein the sleeve inserts are non-rotational with respect to the hosel assembly and the adjustment member.
