Apparatus for fitting a golf club to a player
First Claim
1. Apparatus for fitting the length of a golf club and the club head-to-shaft angle to an individual person, which comprises:
- a fitting club having the overall configuration of a standard golf club with a shaft, grip and head;
said shaft including a first portion carrying said grip and a second portion connected to said head;
said first and second shaft portions relatively telescoping to vary the shaft length from grip to head;
said head mounted for pivoting about a pivot point at the connection of said shaft and head to vary the head-to-shaft angle;
means for determining the shaft length when said grip is held with the shaft telescoped to a selected length which comprises;
a generally "L" shaped electrically insulating panel;
a first leg of said panel extending into said second shaft portion and pivotable therewith;
a first series of spaced electrical contact areas along said first leg each representing a specific shaft length;
a first continuous electrical contact means along said first leg adjacent to said first series of spaced contacts;
a first movable connection contact secured to said second shaft portion for movement along said first series of contacts and said first continuous contact to connect therebetween;
electrical circuit means for generating a digital display corresponding to the one of said first spaced contacts engaged by said first movable connection contact to indicate the overall shaft length;
means for determining the head-to-shaft angle when said grip is held with said shaft at a selected angle to said head;
first display means for displaying indicia indicating the shaft length when said grip is held at a selected length and angular position;
second display means for displaying indicia indicating the head-to-shaft angle when said grip is held at a selected length and angular position;
whereby a person may hold the grip and assume a normal golf stance and said display means will display the actual shaft length and head-to-shaft angle so that the person can select a corresponding normal club.

Abstract
An apparatus for fitting golf club length and head-to-shaft angle to an individual person. The fitting club shaft is in two telescoping portions. A conventional grip is provided at the end of the first portion and the end of the second portion is pivotally connected to a conventional club head. A generally "L"shaped electrically insulating panel has one leg extending into the second shaft portion and the other leg extending into a cavity in the head. A first series of longitudinally spaced electrical contacts on the first end are adapted to be contacted by a connection contact on the movable first shaft portion to send an electrical signal indicating club length. A second series of spaced electrical contacts are radially arranged on the second leg about the shaft pivot point. The second series of contacts is adapted to be contacted by a second connection contact to send an electrical signal indicating head-to-shaft angle. A person grasps the fitting club grip and assumes a normal golf stance. A digital display provides a visible readout on an adjacent tower of the club length and head-to-shaft angle selected by the person. A rack attached to the tower carries a number of normal clubs having different lengths and angles, so that the person can select a club having dimensions corresponding to the display.
