Abstract

A golf club is provided and includes an upstanding shank portion and a lower head portion carried by the lower end of the shank portion. The head includes top, bottom, front, rear and inner and outer sides and the shank portion extends upwardly from the head at a point on the top side thereof adjacent the front and inner sides of the head at an angle upwardly and outwardly inclined from the inner side of the head. The inner and outer sides generally parallel each other and the outer side, rear and top sides are substantially mutually right-angularly disposed. The front side or face is rearwardly and upwardly inclined and the bottom side of the head is slightly convex with the axis of curvature thereof disposed in a vertical plane extending at generally right angles to a vertical plane containing the shaft portion of the club.

Claims

1. A golf club including an upstanding shaft portion having an enlarged head supported from its lower end, said head including top and bottom sides, generally parallel opposite inner and outer sides and front and rear sides, said shaft portion being slightly upwardly and outwardly inclined from the inner side of said head and being joined to the top side of said head adjacent said front side and said inner side thereof, said outer, rear and top sides being substantially mutually right angularly disposed, said front side being at least slightly rearwardly and upwardly inclined relative to said rear side, said bottom side being cylindrically convex about a front-to-rear extending axis, the radius of curvature of said convex bottom side being less than the maximum spacing between said top and bottom sides and the spacing between said inner and outer sides, said front side being inclined more than ten degrees relative to a vertical plane containing said shaft portion.
