Brief Patent Description - Full Patent Description - Patent Application Claims
PRIORITY CLAIM [0001] Pursuant to the provisions of 35 U.S.C. .sctn. 119(e)(1), Applicant claims the priority of U.S. Provisional Patent Application Ser. No. 60/597,292, filed Nov. 21, 2005. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates generally to golf clubs having detachable heads and shafts. More particularly, the invention pertains to a golf club and a related kit in which various selected club heads and shafts may be interchanged and adapted to suit the needs of the user. [0004] 2. Description of the Prior Art [0005] Golf clubs having removable shafts are well represented in the prior art. For example, in U.S. Pat. No. 5,388,827, granted to Reynolds, Jr., three embodiments of a golf putter with a removable shaft are disclosed. A keyway engaged by various shaft locking means, prevents the shaft from rotating. A screw or a double threaded allen bolt threadably engages the lower end of the shaft, and secures it within a bore in the club head. [0006] In U.S. Pat. No. 6,890,269, issued to Burrows, a temporary golf club shaft-component connection is illustrated. A compression nut, an adapter insert with a lower pin, an adapter socket, and an anchor member are used to secure the lower tip of a shaft within the hosel of a club head. Splines are provided on the adapter insert and spline grooves are provided within the adapter socket. [0007] A golf club having an aligning and quick connect-disconnect coupling between the golf club shaft and the club head is shown in U.S. Pat. No. 5,039,098, to Pelz. This arrangement uses an angular alignment surface on the lower end of the shaft which cooperates with an angular alignment stop formed within the heel of the golf club head. A bore, provided within the end of the shaft, is engaged by a machine screw to secure the shaft within the hosel of the club. SUMMARY OF THE INVENTION [0008] The present invention comprises a golf club kit having selectively interchangeable heads and shafts. In this manner, the golfer may experiment with different combinations of golf club heads and shafts, to obtain the optimum golf club construction for the needs of that golfer. In addition, the golf club construction allows the selected shaft to be quickly and easily re-positioned into a plurality of rotational positions with respect to the selected club head, again to optimize the performance of the golf club for the golfer. [0009] The upper face of a club head includes a shaft hosel, provided with a recessed sleeve therein. The recessed sleeve includes sidewalls, an open top, and an open bottom. A receiver, having a bore provided with a plurality of spline grooves, is secured within the sleeve. The receiver fits snugly within the sleeve and may be epoxy glued or welded to resist rotation or accidental removal. A recessed, elongated screw port is provided in the lower face of the club head. The screw port is axially aligned with the open bottom in the floor of the sleeve and the bore in the receiver. [0010] The club shaft includes a conventional hand grip on its upper end and a hosel connector on its lower end. The hosel connector has a lower portion provided with a plurality of external splines. The lower portion is also provided with a threaded bore having an open end. The upper portion of the hosel includes a circumferential flange, having an downwardly and outwardly flaring, arcuate sidewall. [0011] The hosel connector of a selected shaft is inserted into the receiver of a selected club head in a selected rotational position. The threaded end of a headed screw is passed upwardly through a passageway in the upper end wall of the screw port. The screw end is threadably installed within the bore of the hosel connector. The head of the screw tightens against the end wall, and the hosel connector flange is compressed securely against the upper end of the receiver.
