ABSTRACT:
A putter having a head, the angle of which is adjustable relative to the shaft, includes a shaft having a lower end secured to a rotatable member rotatably disposed within a bore in the golf club head. The bore includes a longitudinally-elongate upper portion adjacent the upper surface of the head which restricts the range of motion of the shaft. The upper portion prevents movement of the shaft about the axis of the head and restricts the pivotal movement of the shaft to between about 30 degrees and 90 degrees relative to the head. A resilient locking member selectively locks and unlocks the rotatable member within the golf club head, thereby selectively permitting adjustment of the golf club shaft-head angle. Since the locking member is resilient, a golfer is able to adjust the angle merely by applying weight or force.
