Abstract

A club head and hosel assembly providing adjustable loft angles wherein the adjustment ring is located within a housing in the hosel and a one-way ratchet engagement is used to adjust the loft angle by alternately rotating the club head in one direction and then the other with respect to the hosel.

Claims

1. A golf club head and hosel assembly having adjustable loft angles which comprises:

a club head, a ring member, a hosel, and a nut for attaching said hosel and said ring member to said club head;

said club head having a heel portion from which a threaded cylindrical post extends and having a plurality of teeth formed in said heel portion at a base of said post,

said hosel having a gear housing formed at one end thereof, said gear housing being sufficiently deep to receive and enclose said ring member in said housing when said housing and said ring member are assembled with said club head, and a plurality of teeth at a base of said gear housing for engaging said ring member,

said ring member having first and second ends having first and second axially extending surfaces and having first and second sets of teeth formed, respectively said first and second ends of said surfaces for engaging, respectively, said teeth in said heel portion and said teeth in said gear housing,

said ring member being assembled with said club head and said hosel such that said first and second sets of teeth in said ring member engage, respectively, said teeth in said heel portion of said club head and said teeth in said gear housing and said ring member is protectively enclosed and concealed from view within said gear housing, and

said nut member being threadedly tightened on said post to thereby hold said assembly together.

2. The golf club head and hosel assembly of claim 1 wherein said assembly consists essentially of said club head, said ring member, said hosel, and said nut.

3. The golf club and hosel assembly of claim 1 wherein loft index markings are present on said club head and said hosel.

4. The golf club head and hosel assembly of claim 1 wherein said teeth in said heel portion, said sets of teeth in said ring member and said teeth in said gear housing provide a one-way interlocking engagement wherein by loosening said nut and rotating said club head in a first direction, said teeth in said heel portion rotate with respect to said first set of teeth in said ring member, and by rotating said club head in an opposite second direction, said second set of teeth in said ring member rotate with respect to said teeth in said gear housing.

5. The golf club head and hosel assembly of claim 4 wherein said hosel includes a ridge member extending from an outer surface thereof.

6. The golf club head and hosel assembly of claim 5 wherein said assembly further comprises a locking lever, said lever having a housing formed therein for receiving and engaging said nut in multiple positions such that by rotating said lever, said nut can be tightened and loosened and said lever can aligned with said hosel when said nut is tightened.

7. The golf club and hosel assembly of claim 6 wherein said club head is perimeter weighted.

8. The golf club head and hosel assembly of claim 6 wherein said club head and said hosel are aligned in an incrementally reduced offset alignment.

9. An improved golf club with adjustable loft angles comprising a golf club shaft and a golf club head and hosel assembly, said golf club head and hosel assembly including a club head, a ring member, a hosel, and a nut for attaching said hosel and said ring member to said club head;

said club head having a heel portion from which a threaded cylindrical post extends and having a plurality of teeth formed in said heel portion at a base of said post,

said hosel having a gear housing formed at one end thereof, and gear housing being sufficiently deep to receive and enclose said ring member in said housing when said housing and said ring member are assembled with said club head, and a plurality of teeth at a base of said housing for engaging said ring member,

said ring member having first and second end and having first and second axially extending surfaces and having first and second sets of teeth formed respectively, in said first and second ends of said surfaces for engaging, respectively, said teeth in said heel portion and said teeth in said gear housing,

said ring member being assembled with said club head and said hosel such that said first and second sets of teeth in said ring member engage, respectively, said teeth in said heel portion of said club head and said teeth in said gear housing and said ring member is protectively enclosed and concealed from view within said gear housing, and

said nut member being threadedly tightened on said post to thereby hold said assembly together.

10. The golf club of claim 9 wherein said golf club head and hosel assembly consists essentially of said club head, said ring member, said hosel and said nut.

11. The golf club of claim 9 wherein loft index markings are present on said club head and said hosel.

12. The golf club of claim 9 wherein said golf club shaft is a collapsible shaft.

13. The golf club shaft of claim 12 wherein said teeth in said heel portion, said sets of teeth in said ring member and said teeth in said gear housing provide a one-way interlocking engagement wherein by loosening said nut and rotating said club head in a first direction, said teeth in said heel portion rotate with respect to said first set of teeth in said ring member, and by rotating said club head in an opposite second direction, said second set of teeth in said ring member rotate with respect to said teeth in said gear housing.

14. The golf club of claim 12 wherein said golf club shaft includes three telescopic sections.

15. The golf club of claim 14 wherein said hosel includes a ridge member extending from an outer surface thereof.

16. The golf club of claim 14 wherein said golf club further comprises a cap at an end of said shaft opposite said hosel.

17. The golf club of claim 14 wherein said assembly further comprises a locking lever, said lever having a housing formed therein for receiving and engaging said nut in multiple positions such that by rotating said lever, said nut can be tightened and loosened and said lever can be aligned with said hosel when said nut is tightened.

18. The golf club of claim 17 wherein said club head is perimeter weighted.

19. The golf club of claim 17 wherein said club head and said hosel are aligned in an incrementally reduced offset alignment.
