ABSTRACT:
An extensible and retractable golf club is provided, including interior and exterior telescoping hollow shaft members slidably interconnected, a handle securely attached to the free end of the exterior shaft member, a club head securely attached to the free end of the interior shaft member, and a locking mechanism which temporarily maintains the two telescoping shaft members in a desired position relative to each other. The locking mechanism includes first and second pieces which are transferrable from an open position, wherein the two pieces are axially aligned and the two telescoping shaft members slidable relative to each other, to a closed position, wherein the two pieces are not axially aligned and the two telescoping shaft members are not slidable relative to each other. Transfer of the two pieces of the locking mechanism from the open to the closed position is accomplished by twisting the shaft members relative to each other less than one full revolution.
