Abstract

According to one aspect of the present invention there is provided an adjustable connector including at least two parts, each having a main body with a bore having a longitudinal axis therein, wherein an external surface of the main body of a first part is configured to bear against an internal surface of the bore of a second part when the first part is at least partially inserted into the bore of the second part to form a connection, characterized in that the positioning of the bores with respect to the main bodies is such that when the parts are connected to each other, rotation of one part with respect to the other changes the inclination of the longitudinal axes of the bores with respect to one another.

First claim

I claim:

1. An adjustable connector to connect a golf club head and a golf club shaft, the adjustable connector comprising:
a first part having an outer wall configured to be inserted into a hosel of a golf club head and configured to rotate inside the hosel between a first plurality of rotational positions, said first part having a first internal inclined bore; and
a second part configured to be coupled to a shaft and having an outer wall received in said first internal inclined bore, said second part being rotatably repositionable within said first internal inclined bore between a second plurality of rotational positions, said second part having a second internal inclined bore configured to receive the shaft; and
wherein the first internal inclined bore includes a spline, key detail, or ridges and grooves that inhibit rotation of the second part with respect to first part when the second part is received within the first internal inclined bore.

2. An adjustable connector as claimed in claim 1 wherein the first and the second inclined bores are inclined with respect to a longitudinal axis of the bore of that part.

3. An adjustable connector as claimed in claim 1 wherein the outer wall of the first part is a straight-sided cylinder.

4. An adjustable connector as claimed in claim 1 wherein at least one part includes a marking configured to indicate the orientation of the part.

5. An adjustable connector as claimed in claim 1 wherein at least one part is configured to be releasably connected to either the golf club shaft or the golf club head.

6. An adjustable connector as claimed in claim 1 wherein the second part is slidably received within the first part.

7. An adjustable connector as claimed in claim 1 , wherein rotating the first part through the first plurality of rotational positions changes a first angular relationship between the golf club head and the golf club shaft.

8. An adjustable connector as claimed in claim 7 , wherein rotating the second part through the second plurality of rotational positions changes a second angular relationship between the golf club head and the golf club shaft, wherein the second angular relationship is independent of the first angular relationship.

9. An adjustable connector as claimed in claim 8 , wherein the first and second angular relationships are a lie angle of a golf club head and a loft angle of said golf club head.

10. An adjustable connector as claimed in claim 8 , wherein the first and second angular relationships are a loft angle of a golf club head and a face angle of said golf club head.

11. An adjustable connector to connect a golf club head and a golf club shaft, the adjustable connector comprising a pair of radially nested mutually independently rotatable members, one of said members having an outer wall disposed within the golf club head and the other of said members having a bore having the golf club shaft disposed therein, both members having inclined bores whereby two angular relationship parameters between said golf club head and said golf club shaft may be adjusted independently of each other; and
wherein the at least one of the rotatable members includes a spline, key detail, or ridges and grooves that inhibits relative rotation between the rotatable members when in the radially nested arrangement.

12. An adjustable connector as claimed in claim 11 wherein the inclined bores are inclined with respect to a longitudinal axis of the bore of that member.

13. An adjustable connector as claimed in claim 11 wherein at least one member includes a marking configured to indicate the orientation of the member.

14. An adjustable connector as claimed in claim 13 , wherein the marking includes a sequence of numbers.

15. An adjustable connector as claimed in claim 14 , wherein the sequence of numbers is arranged around one or more of a rim of the first part and a rim of the second part.

16. An adjustable connector as claimed in claim 11 wherein at least one member is configured to be releasably connected to either the shaft or the head.

17. An adjustable connector as claimed in claim 11 , wherein the two angular relationship parameters are two of the following: a lie angle of the head, a loft angle of the head, and a face angle of the head.
