ABSTRACT:
A golf club includes an articulated release joint connecting the lower and upper sections of the shaft in alignment. The release joint includes a lower link fixed to the lower section of the shaft and an upper link fixed to the upper section of the shaft. The links are pivotally connected for relative rotation in response to impact on the shaft to permit the lower section to rotate relative to the upper section to relieve the stress of impact. The pivot is on a threaded hinge pin which is adjustable to vary the friction within the release joint and thereby the responsiveness of the joint to impact on the shaft.
