View Patent ↗Disclosed herein is a golf club including a shaft, a club head and several devices for releasably connecting the shaft to the club head.
1. A golf club comprising:
a shaft;
a club head; and
a connection system releasably connecting the shaft to the club head, said connection system further comprises;
a first hosel part, distinct from the shaft wherein the shaft passes through, is connected to the shaft,
a second hosel part, distinct from the first hosel part wherein the shaft passes through, is formed integrally with the club head, and
a hosel insert, distinct from the first and second hosel part, is disposed between the two hosel parts to alter a loft or lie of the golf club, wherein the hosel insert is askew, and wherein an entire tip end of the shaft is able to be removed upward out a top of the second hosel part.
2. The golf club of claim 1 , wherein the hosel insert has a top line and a bottom line, wherein the top line is not parallel to the bottom line.
3. The golf club of claim 1 , wherein a first side of the hosel insert and a second side of the hosel insert have different lengths.
4. The golf club of claim 3 , wherein the first side of the hosel insert is opposite to the second side of the hosel insert.
5. The golf club of claim 1 , wherein the first hosel part further comprises a first serrated surface located near a bottom of the first hosel part;
the second hosel part further comprises a second serrated surface located near a top of the second hosel part, and
the hosel insert further comprises a third serrated surface located near a top of the hosel insert and a fourth serrated surface located near a bottom of the hosel insert.
6. The golf club of claim 5 , wherein the first serrated surface and the third serrated surface are adapted to engage one another to prevent axial rotation between the first hosel part and the hosel insert, and
wherein the second serrated surface and the fourth serrated surface are adapted to engage one another to prevent axial rotation between the second hosel part and the hosel insert.
7. The golf club of claim 6 , wherein the first serrated surface and the third serrated surface are the only contacting surface between the first hosel part and the hosel insert, and
wherein the second serrated surface and the fourth serrated surface are the only contacting surfaces between the second hosel part and the hosel insert.
8. A golf club comprising:
a shaft;
a club head; and
a connection system releasably connecting the shaft to the club head;
said connection system further comprises;
a first hosel part, having a substantially tubular shape, distinct from the shaft wherein the shaft passes through, is connected to the shaft;
a second hosel part, formed integrally with the club head wherein the shaft passes through, forms a hosel portion of the club head; and
a hosel insert, in the shape of a ring, distinct from the first and second hosel part, is disposed between the two hosel parts,
wherein the hosel insert is askew and wherein an entire tip end of the shaft is able to be removed upward out a top of the second hosel part.
9. The golf club of claim 8 , wherein the first hosel part further comprises a first congruent surface located near a bottom of the first hosel part;
the second hosel part further comprises a second congruent surface located near a top of the second hosel part, and
the hosel insert further comprises a third congruent surface located near a top of the hosel insert and a fourth congruent surface located near a bottom of the hosel insert.
10. The golf club of claim 9 , wherein the first congruent surface and the third congruent surface are adapted to engage one another to prevent axial rotation between the first hosel part and the hosel insert, and
wherein the second congruent surface and the fourth congruent surface are adapted to engage one another to prevent axial rotation between the second hosel part and the hosel insert.
11. The golf club of claim 10 , wherein the hosel insert has a top line and a bottom line, wherein the top line is not parallel to the bottom line.
12. The golf club of claim 11 , wherein a first side of the hosel insert and a second side of the hosel insert have different lengths.
