Abstract

A hosel fitting for connecting a shaft to one of a plurality of club heads comprises a first portion of a tubular structure configured to be affixed to the end of the shaft and a second portion of the tubular structure configured to be received by a bore in a club head. The second portion of the tubular portion can be configured to extend down into the bore. The hosel fitting can also comprise a fastener receiving portion for receiving a fastener configured to affix the hosel fitting to any one of the plurality of club heads.

Claims

1. A hosel fitting for connecting a shaft to one of a plurality of club heads comprising:

a first portion of a tubular structure configured to be affixed to the end of the shaft;

a second portion of the tubular structure configured to be received by a bore in a club head, the second portion of the tubular portion extending downwardly into the bore;

a fastener receiving portion for receiving a fastener configured to affix the hosel fitting to any one of the plurality of club heads; and

wherein the bore, hosel fitting, and shaft are always substantially in line.

2. The hosel fitting of claim 1, wherein the fastener receiving portion comprises a female-threaded fastener receiver configured to receive a male-threaded fastener.

3. The hosel fitting of claim 2, wherein the male-threaded fastener comprises a bolt.

4. The hosel fitting of claim 1, wherein the fastener receiving portion comprises a male-threaded fastener receiver configured to receive a female-threaded fastener.

5. The hosel fitting of claim 1, wherein the second portion of the tubular structure is configured to extend downwardly into the bore until it contacts a base of the bore.

6. A golf club assembly, comprising:

a fastener;

a club head comprising a bore;

a shaft; and

a hosel fitting for connecting the shaft to the club head, the hosel fitting having;

a first portion of a tubular structure configured to be affixed to the end of the shaft;

a second portion of the tubular structure configured to be received by the bore in the club head, the second portion of the tubular portion extending downwardly into the bore;

a fastener receiving portion for receiving the fastener, the fastener configured to affix the hosel fitting the club head, wherein the bore, hosel fitting, and shaft are always substantially in line.

7. The golf club assembly of claim 6, wherein the fastener receiving portion comprises a female-threaded fastener receiver, and wherein the fastener is a male-threaded fastener.

8. The golf club assembly of claim 7, wherein the male-threaded fastener comprises a bolt.

9. The golf club assembly of claim 6, wherein the fastener receiving portion comprises a male-threaded fastener receiver, and wherein the fastener comprises a female-threaded fastener.

10. The golf club assembly of claim 6, wherein the bore comprises a base, and wherein the second portion of the tubular structure is configured to extend downwardly into the bore until it contacts the base of the bore.

11. The golf club assembly of claim 10, wherein the bore further comprises an aperture in the base, wherein the fastener is configured to extend through the aperture to mate with the fastener receiving portion.

12. The golf club assembly of claim 6, wherein the bore is configured to orient the shaft properly when the shaft is connected to the club head using the hosel fitting.

13. The golf club assembly of claim 6, wherein the fastener is configured to allow the club head to be exchange with a differnet club head.

14. The golf club assembly of claim 13, wherein the different club head comprises a different center of gravity relative to the first club head.

16. The golf club assembly of claim 6, wherein the club head comprises a recess substantially below the bore, the recess configured so that the fastener will not strike the ground when the golf club assembly is swung.

17. The golf club assembly of claim 6, wherein the golf club head is a wood type golf club head.

18. The golf club assembly of claim 6, wherein the golf club head is an iron type golf club head.

19. The golf club assembly of claim 6, wherein the golf club head is a hybrid type golf club head.

15. The golf cub assembly, wherein the fastener allows the shaft to be exchange with a different shaft.

20. A system for fitting a golfer fro a golf club, comprising:

at least one club head comprising a bore;

a fastener; and

at least one shaft assembly comprising a shaft and a hosel fitting, the hosel fitting comprising;
