GOLF PUTTER WITH CONSTRAINDED LIE ANGLE ADJUSTABILITY

摘要

Disclosed are systems and methods of adjusting the playing orientation of the head of a golf club. An adjustment to the axis of the shaft in reference to the vertical plane is constrained within minimum and maximum limits, so as to conform to current and proposed changes to the United States Golf Association (USGA) rules of play. The fine adjustment within these constraints cannot be readily made, and all adjustable parts are firmly fixed, so there is no reasonable likelihood of them working loose during a round. The adjustments to the club are designed such that during a stipulated round, the playing characteristics of a club cannot be purposely changed by adjustment or by other means.

主权项

1. An adjustable golf club comprising:
a golf club shaft; a clubhead comprising:
a hollow body wherein a bottom surface of said body defines an upper boundary confine of a cavity with said hollow body, and a top surface of said body provides a crown with an opening disposed on said crown such that a proximal end of said club shaft is able to protrude through said opening;a retaining plate that attaches to said body wherein a top surface of said plate defines the lower boundary confine of said cavity with said hollow body, and a bottom surface of said plate provides a sole;a rocker member disposed within said cavity comprising:
a cylindrical rocker pivot that allows the assembly to rotate about a pivot center;a toe rocker arm that extend forward from a pivot center;a heel rocker arm that extends rearward from said pivot center; and,a cylindrical bore that extends from a top portion into said rocker member to retain a distal end of said club shaft;wherein the confines of said cavity allow said rocker member limit single plane rotation about said pivot center constrained by interference between said rocker arms and the confines of said cavity at minimum and maximum angular limits; and,a lie adjustor that facilitates adjustment of the rotational position of said rocker member in a plane parallel to a striking face of said golf club within said constraints of said rocker arm interference and rigidly locks the rotation of said rocker member in place between said minimum and maximum angular limits to establish a club lie angle.
