Abstract
A golf club with a quick release head comprising a shaft which has an upper handle end a lower hosel end formed in a tubular configuration. The hosel end has a bore centrally formed therein. Screw threads formed within the bore extend from the hosel end of the shaft inwardly a predetermined distance. A head at the lower head end has an upwardly extending hosel at the hosel end and a bore formed within the hosel end. The interior diameter of the bore of the hosel is essentially the same as the internal bore in the shaft and the exterior diameter of the hosel is essentially the same as the exterior diameter of the shaft at the hosel end. The hosel has a diametric aperture which extends therethrough. A coupling rod has a threaded upper end with screw threads matable with the screw threads in the bore of the shaft and a lower end formed with a diametric aperture extends therethrough in alignment with the diametric aperture in the hosel. A quick release pin is positionable through the apertures of the hosel and rod to secure a preselected head in operative association with the rod and shaft.
