US 5,709,613 A · Adjustable back-shaft golf putter

Abstract

A golf putter is provided whose hosel is connected horizontally to the rear surface of the putter head and curves 90.degree. to vertical, attaching to a putter shaft. Two threaded pegs are set into the rear surface of the putter head, and a number of variable weights having threaded holes accommodate the threaded pegs can be interchangeably mounted onto the rear surface of the putter head in order to adjust the putter balance and weight characteristics as desired. In addition, the angle between the shaft and the vertical can be varied to any angle for either a right- or a left-handed golfer. In a first embodiment, the putter head comprises a recess in its rear surface into which the hosel is rotatably mounted and a threaded bore extending from the top surface down through to the recess. The hosel, which has holes around the circumference of its end, is placed into the recess and a threaded screw is inserted through the bore and into one of the hosel holes, thereby setting the hosel and its attached shaft at a desired angle. In another embodiment, the horizontal region of the hosel is composed of two portions joined by fitted ratchet teeth and set together at a desired angle by a threaded screw that extends horizontally through the horizontal region of the hosel. The hosel can be set so that the shaft angle may be set at no less than 10.degree. from vertical to conform with U.S. Golf Association rules and regulations.

Dependent claims

An adjustable golf putter comprising:

an elongated linear shaft;
a putter head having a top surface, a from surface defining a substantially planar surface for contacting a golf ball, a rear surface opposed to said front surface, a recess in said rear surface and a threaded bore for accommodating a threaded screw extending downward through said putter head from said top surface into said recess;
and
a substantially L-shaped hosel having a first end for attachment to said shaft along a substantially vertical axis and a second end for attachment to said rear surface of said putter head along a substantially horizontal axis, said second end of said hosel comprising a plurality of holes about its circumference for receiving said threaded screw;
and
weight means removably mounted on said rear surface of said putter head for adjusting the weight and balance of said golf putter:
whereby said hosel can be rotated about said substantially horizontal axis within said recess in said putter head to set said attached shaft at a desired angle from vertical and said screw can be threaded into said threaded bore and inserted into one of said holes in said hosel to set said hosel within said recess and said attached shaft at said desired angle from vertical.
