ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates generally to golf equipment and, in particular, to a golf club head with a notch for making loft and lie adjustments.
U.S. Pat. No. 4,512,577 to Karsten Solheim discloses an iron type golf club having a club head and a shaft. The club head includes a body, and a narrowed neck which connects the body to a hosel which receives the lower end of the shaft. The narrowed neck has a maximum dimension at its mid section that is smaller than the outside diameter of the hosel. When adjusting loft and lie angles of the club head, bending occurs at the narrowed neck. While the club head disclosed in the Solheim patent permits satisfactory loft and lie adjustments, it is recognized that further improvements are possible.
SUMMARY OF THE INVENTION
A golf club head according to an improvement includes a front face arranged for impact with a golf ball, a heel portion and a toe portion. A hosel having a neck connected to the heel portion of the body has an outside diameter. The hosel contains a bore for receiving one end of a golf club shaft having a longitudinal axis, and the bore has a desired orientation relative to the body. The hosel neck has an outer peripheral surface including an upper surface and a lower surface when viewed from a direction which is generally normal to the front face. A notch is formed only in the lower surface of the hosel neck and extends around only a portion of the hosel neck. The notch has a depth that varies along its length. A critical dimension measured between the upper surface of the hosel neck and a point on the depth of the notch is less than the outside diameter of the hosel so that the desired orientation of the bore relative to the body may be adjusted by bending the neck at the notch. The hosel has a top edge disposed at an acute angle to the shaft longitudinal axis when viewed in the direction which is generally normal to the front face.
