Patent ID: 8157666

Claim:
A golf swing teaching device, for preventing medial rotation of a golfers right arm in a backswing and in particular during a downswing of a swing of a golfer's club and consequently assisting in delivering a club head on a path approaching a golf ball in which the path is slightly on the inside (to the left) or square to an intended target line, the golf swing teaching device comprising: a lower elongated member which, in use, attaches to, and extends along, a lower part of the golfer's right arm below an elbow joint of the right arm; an upper elongated member which, in use, attaches to, and extends along, an upper part of the right arm above the elbow joint; an elbow joint which pivotally joins the lower and upper elongated members together, with relative movement of the upper and lower elongated members being restricted to within a single plane; a rigid counter acting elongated member pivotally attached to and mounted on the lower and upper elongated members and wherein the counter acting elongated member extends from a pivotal attachment on the lower elongated member through a pivotal attachment on the upper elongated member; a holding device which, in use, attaches to a waist of the golfer which includes an elongated pivoting arm having an elongated opening with rigid walls wherein the elongated opening is located at the end opposite to the pivoting end of the pivoting arm with the elongated pivoting arm attaching to a ratchet device (which allows pivoting in only one direction) by means of a pivoting shaft with the ratchet device attaching to a rounded elongated base section extending in opposite directions, away from the ratchet device and wherein the rounded elongated base section attaches to the waist of the golfer, and whereby the elongated opening allow the counter acting elongated member to slide into, move around and slide out of the elongated opening at certain stages before and during the golf swing with the holding device together with the counter acting elongated member inserted into the elongated opening of the pivoting arm acting as a resistance force during the downswing preventing movement of the end of the counter acting elongated member away from the golfers torso and movement of the counter acting elongated member out of the elongated opening and free of the holding device, thereby to prevent medial rotation of the golfer's right arm during the downswing.
