ABSTRACT:
An adjustable golf putter includes a shaft having a lower end, a pivotal pin attached to the lower end, and a head pivotally retaining the pivot pin. The pivotal pin is pivotally disposed through a slot which is formed through an upper surface of the head and extends downwardly to a longitudinal duct. A supporting member and notches of an abutment are disposed in the duct of the head and only allow movement along the longitudinal axis of the head by abutting against the pivotal pin. A pair of locking members are disposed through the head and abut against the shaft locking the shaft in a selected angular position. The pivotal pin extending in a first direction inserts through the slot and is disposed in the duct. The pivotal pin pivotally lodges within the notches by rotating the pivotal pin roughly 90 degrees from the first direction to a second direction. The support member is then inserted preventing vertical movement of the pivotal pin. Locking members lock the shaft in the selected angular position. The range of movement of the shaft relative to the head is restricted to a single plane movement. Movement along the longitudinal axis of the head is restricted to roughly 30 degrees to 90 degrees relative to the head. Locking members are inserted through the head to selectively lock and unlock the pivotal pin within the head, thereby selectively permitting adjustment of the golf club shaft-head angle.
