Abstract

An Adjustable Golf Club adapted to serve the functions of a plurality of golf clubs has a single easily manipulated locking device accommodating adjustment of the club length, loft and lie angle. The club has a blade with a ball striking face, a curved hosel extending from the heel of the blade, a shaft with a fitting slidably receiving the hosel, and a locking screw securing the hosel in a number of related positions to reproduce the lengths, lofts and lie angles of, for example, Nos. 2-10 irons. Indicia on the hosel registers with a window in the fitting to identify the iron number for each adjusted position.

Claims

1. An adjustable golf club for simultaneously adjusting the length, loft, and lie angles of the club thereby being adapted to serve the functions of a set of successively numbered golf clubs wherein these clubs decrease in length and increase in loft and lie angles from the lowest numbered club to the highest numbered club, said adjustable golf club comprising an elongated shaft, a hand grip on one end of the shaft, a fitting on the other end of the shaft having a curved passage therethrough substantially coplanar with the shaft axis and rearwardly directed relative to the shaft, a club head having a striking face, a rear surface, a top surface, a sole surface, a toe end and a heel end, an elongated curved hosel extending from the heel end of the club head upwardly and rearwardly therefrom and defining an acute lie angle and with its curvature being in a plane of curvature inclined relative to a vertical plane perpendicular to the plane of the striking face of the club head, said hosel being slidably mounted in said curved passage of the fitting, means on the fitting for locking the hosel in fixed position in said passage, said hosel length and said curvature of the hosel being such as to simultaneously change the effective length of the club, the lie angle of the sole relative to the axis of the shaft and the loft angle of the striking face of the club head to reproduce the club lengths, lie angles, and loft angles of said set of golf clubs when said fitting is locked to the hosel in the appropriate position.

2. The adjustable golf club of claim 1 including indicia spaced along the length of the hosel and a window in said fitting registering with said indicia whereby the indicia exposed in the window will identify the setting of the adjustable club.

3. The adjustable golf club of claim 1 wherein said means on the fitting locking the hosel in fixed position in the passage is a clamp on the fitting.

4. The adjustable golf club of claim 1 wherein the hosel is the arc of a circle struck from a fixed center on a radius of 12 cm.

5. The adjustable golf club of claim 1 wherein the club is an iron and has a club head with a blade.

6. The adjustable golf club of claim 1 wherein the inclination of the plane of curvature relative to the vertical plane perpendicular to the plane of the striking face of the club head, is 86°
