ABSTRACT:
BACKGROUND OF THE INVENTION
Golf rules and the size of golf bags limit the number of clubs a golfer can carry. The speed of putts on putting greens vary depending on a number of different conditions. Some greens are fast and others are slow. Many golfers feel there is an appropriate putter for each of these different greens. Putters may vary with the softness or hardness of the putting face.
A number of different approaches to providing interchangeable golf heads are suggested in prior art patents such as Wheeler 3,524,646 and Evancho 3,424,459. Neither of these putters, however, allow use of the conventional putter head but instead, require special heads and shafts. What is needed is a golf club shaft that will interchangeably fit into any putter head shank.
SUMMARY OF THE INVENTION
Any desired club head, and in particular putter club heads, can be interchangeably connected to the conventional shaft which has been slightly modified to releasably engage the shank.
A rod extends the length of the hollow shaft and threadably engages a conical wedge on its lower end which is adapted to move in and out of the lower end of the hollow shaft which has been longitudinally slotted around its periphery to allow the side wall of the shaft to be pressed outwardly by the wedge against the interior wall of the hollow shank. A control assembly is provided on the upper end of the rod to allow for rotation of the rod to cause the wedge to move in and out of the lower end of the hollow shaft. A cap is placed over the upper end of the shaft obscuring the nut locked onto the shaft for rotating the shaft.
It is thus seen that a conventional golf club shaft could be modified by serrating the lower end to provide slots and adding a rod extending the length of the shaft and providing a wedge on the lower end. The maximum diameter of the wedge is substantially equal to the outer diameter of the shaft which in turn is substantially equal to the interior diameter of the club head shank. Thus, the thickness of the shaft wall is sufficient to allow for a friction fit connection between the shaft and the club head shank by pulling the wedge tight into the lower end of the shaft by operation of the nut on the upper end of the shaft which bears against the upper end of the shaft.
