发明名称 GOLF SWING PRACTICE BOARD AND METHOD OF USE
摘要 A golf swing training system and method includes a golf club, a light connected to or incorporated in the golf club, and a graphical display upon which a light is projected when a golfer swings the club. The graphics include various markings that indicate foot position and that can be observed to generate the desired golf swing. The golfer moves the clubhead and then the light along a first line until the light reaches a point at the top of the golfer's backswing. As the golfer begins the downswing, a third line provides a visual indication of the orientation of the club shaft at a midpoint of the downswing, when the shaft is parallel to the ground, and then the golfer swings the clubhead to impact the ball on plane and square to the target line, and other markings indicate foot position.
