Golf club with two piece hosel
View Patent ↗The exemplary embodiment of the present invention comprises a non-contiguous hosel for attaching a golf club shaft to a golf club head. In an exemplary embodiment, two inserts are used to form a hollow shaft receptacle, or hosel. The two inserts are placed at substantially opposite portions of the club head. The placement of the inserts may be manipulated to vary the lie or loft angle of the golf club. In other embodiments, the two inserts may be joined, or multiple inserts may be used, in order to form a non-contiguous hosel.
1. A golf club, comprising:
a substantially hollow club head comprising a body having a face, a neck, a crown, and a sole;
an elongate club shaft;
a first insert operatively connected to a first part of said club head to pass said club shaft, said first insert comprising a first density;
a second insert operatively connected to a second part of said club head substantially opposite said first insert to pass said club shaft, said second insert comprising a second density; and
wherein a ratio of said second density to said first density is between 10:1 and 3:1;
and wherein the first insert and the second insert are arranged to substantially prevent movement of the shaft, including movement of the shaft in a transverse direction, relative to the substantially hollow club head.
2. The apparatus according to claim 1 , wherein said first and second inserts form a non-contiguous hosel that covers only a predetermined portion of said golf club shaft that passes through said club head.
3. The apparatus according to claim 1 , wherein said first and second inserts allow said club shaft to pass at a selectable lie angle.
4. The apparatus according to claim 1 , wherein said first and second inserts allow said club shaft to pass at a selectable loft angle.
5. The apparatus according to claim 1 , wherein said first and second inserts form a hosel from a substantially minimum amount of material necessary to create a shaft receptacle.
6. The apparatus according to claim 1 , wherein said first part of said club head comprises a predetermined crown portion of said club head.
7. The apparatus according to claim 1 , wherein said second part of said club head comprises a predetermined sole portion of said club head.
8. The apparatus according to claim 1 , wherein said first and second inserts are formed from one of a polymer, a metal, an alloy, and a plastic.
9. The apparatus according to claim 1 , wherein said first insert is formed from at least one of cellulose, glass-filled ABS, graphite, titanium, aluminum, or thermoplastics.
10. The apparatus according to claim 1 , wherein said first and second inserts are formed from substantially different material.
11. The apparatus according to claim 1 , wherein said first and second inserts are adhesively bonded to said club head.
12. The apparatus according to claim 1 , wherein said club shaft is adhesively bonded to said first and second inserts.
13. The apparatus according to claim 1 , wherein said second insert is formed from at least one of cellulose, glass-filled ABS, graphite, titanium, aluminum, or thermoplastics.
14. A golf club, comprising:
a substantially hollow club head comprising a body having a face, a neck, a crown, and a sole;
at least two inserts operatively connected to predetermined parts of said body to form a non-contiguous hosel inside said club head, wherein the first insert comprises a first density and the second insert comprises a second density;
an elongate club shaft configured and dimensioned to pass through each of said inserts; and
wherein a ratio of the second density to the first density is at least 2:1;
and wherein the at least two inserts are arranged to substantially resist motion of the shaft, including transverse motion, relative to the substantially hollow club head.
15. The apparatus according to claim 14 , wherein said inserts have one of:
similar lengths; and
different lengths.
16. The apparatus according to claim 14 , wherein said inserts have one of:
similar thickness; and
different thickness.
17. The apparatus according to claim 14 , wherein said inserts include perforations.
