ABSTRACT:
The invention comprises a golf practice swing apparatus. The apparatus has a base support with a main pole extending upward at a slight angle toward the position where a golfer would normally stand. A swing arm is mounted on the main pole and pivotally mounted to rotate on an axis perpendicular to the length of the main pole and in a plane parallel to the main pole. The swing arm has a spring biased lever pivotally mounted to the lower end of the swing arm to pivot in generally the same plane as the swing arm rotates. A club head is mounted to the lower end of the lever and a club shaft is pivotally mounted to the club head and projects toward the position the golfer would normally stand. The club head lies in the general plane of the swing with its face perpendicular to the plane. The swing arm has a pivotally mounted section to allow the lever arm and club head to swing out of the plane to one side in a direction toward the golfer, but prevents the lever arm and club head from swinging out of the plane in the opposite direction toward the pole. The golfer may swing the shaft to swing the club head in a normal golf swing. With light laterally urging of the shaft toward the pole by the golfer while performing the swing, the apparatus will maintain the club head in the same plane of the swing arm throughout the swing and maintain the club face perpendicular to the line of travel while swinging the club in the normal back swing and forward swing. This gives the golfer the feel of swinging a club in the same plane and the club face perpendicular to the line of travel for an entire golf swing.
