发明名称 Golf swing training device
摘要 A passive golf swing training apparatus used in teaching a golfer the proper fore and aft alignment of the golfer's club in conjunction with a pair of adjustable guide rails that can be set to conform with the particular lie of a golf club. The apparatus provides guidance for the club during the first half of the back stroke from the setup position to the horizonal position. A trigger means, located at the horizonal position, is tripped by the shaft of the golf club, allowing the apparatus to collapse, thereby removing the apparatus as an obstruction on the down stroke.
