Abstract

The present invention is directed at a quick release connection system to facilitate customization of golf clubs. It can be used to interchange shafts, removable weights, or soleplates quickly and easily. Teeth are disposed on the inside of a frame so that a shaft may be inserted with minimal resistance, but cannot be removed without specific steps which may require the use of a simple tool. Strengthening and interlock devices are provided to ensure performance quality akin to traditional golf clubs.

Claims

1. A connection system for assembling a golf club comprising

a plurality of angularly disposed teeth arranged on a first portion of the golf club, said teeth are sized and dimensioned to allow the insertion of a second portion of the golf club into a body of the golf club and resists the withdrawal of said second portion,

wherein said teeth form an acute angle with the direction of insertion.

2. The connection system of claim 1, wherein the first portion comprises a hosel.

3. The connection system of claim 1, wherein the first portion comprises a frame disposed within the hosel.

4. The connection system of claim 1, wherein the first portion comprises a frame disposed on a shaft.

5. The connection system of claim 1, wherein the first portion comprises a sole plate.

6. The connection system of claim 1, wherein the second portion comprises a shaft.

7. The connection system of claim 1, wherein the second portion comprises a removable weight.

8. The connection system of claim 1, wherein the second portion comprises a body portion of the club head.

9. The connection system of claim 1, further comprising a plug.

10. The connection system of claim 1, wherein a channel is scored from the second portion, wherein said channel is adapted to retain said teeth.

11. The connection system of claim 1, further comprising a first and a second interlock devices, wherein said first and second interlock devices interact to prevent rotation of the second portion of the golf club.

12. The connection system of claim 1, further comprising a sliding release collar.

13. The connection system of claim 12, further comprising a removing tool, wherein the removing tool is adapted to push the sliding release collar.

14. The connection system of claim 12, further comprising a removing tool, wherein the removing tool is adapted to pull the sliding release collar.

15. The connection system of claim 1, further comprising a second plurality of teeth.
