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.

Claims

1. A new and improved golf club with a quick release head comprising, in combination:

a shaft having an upper handle end and a lower hosel end formed in a tubular configuration, the hosel end having a bore centrally formed therein, screw threads formed within the bore extending from the hosel end of the shaft inwardly a predetermined distance;

a head having a toe, heel, face, back and sole plate at the lower head end and having an upwardly extending hosel at the hosel end and having a bore formed within the hosel end, the interior diameter of the bore of the hosel being essentially the same as the internal bore in the shaft and the exterior diameter of the hosel being essentially the same as the exterior diameter of the shaft at the hosel end, the hosel having a diametric aperture extending therethrough;

a coupling rod having a threaded upper end with screw threads mated with the screw threads in the bore of the shaft and a length not greater than the length of the threaded portion of the shaft and having a lower end formed with a diametric aperture extending therethrough in alignment with the diametric aperture in the hosel;

a quick release pin positioned through the apertures of the hosel and rod to secure a preselected head in operative association with the rod and shaft;

the upper handle end of the shaft being formed with an interior shaft component with a plurality of diametric holes in axial alignment through one wall of the shaft and having a diametrically enlarged upper extent for receiving a grip, the upper extent comprising an exterior component having a single hole adapted to be aligned with a preselected one of the plurality of holes in the interior shaft component and a supplemental quick release pin positioned through the apertures of the interior and exterior components at the upper handle end of the shaft; and

a spring pin extending through apertures in the shaft and the rod at a location to offset the diameter to ensure a proper rotational orientation between the shaft and the rod.

2. A golf club with a quick release head comprising:

a shaft having an upper handle end and a lower hosel end formed in a tubular configuration, the hosel end having a bore centrally formed therein, screw threads formed within the bore extending from the hosel end of the shaft inwardly a predetermined distance;

a head at the lower head end and having an upwardly extending hosel at the hosel end and having a bore formed within the hosel end, the interior diameter of the bore of the hosel being essentially the same as the internal bore in the shaft and the exterior diameter of the hosel being essentially the same as the exterior diameter of the shaft at the hosel end, the hosel having a diametric aperture extending therethrough;

a coupling rod having a threaded upper end with screw threads mated with the screw threads in the bore of the shaft and having a lower end formed with a diametric aperture extending therethrough in alignment with the diametric aperture in the hosel; and

a quick release pin positioned through the apertures of the hosel and rod to secure a preselected head in operative association with the rod and shaft.

3. The golf club as set forth in claim 2 wherein the upper handle end of the shaft being formed with an interior shaft component with a plurality of diametric holes in axial alignment through one wall of the shaft and having a diametrically enlarged upper extent for receiving a grip, the upper extent comprising an exterior component having a single hole adapted to be aligned with a preselected one of the plurality of holes in the interior shaft component and a supplemental quick release pin positioned through the apertures of the interior and exterior components at the upper handle end of the shaft.

4. The golf club as set forth in claim 2 and further including:

a spring pin extending through apertures in the shaft and the rod at a location to offset the diameter to ensure a proper rotational orientation between the shaft and the rod.
