发明名称 GOLF PRACTICE AID
摘要 A practice aid for use by a golfer practicing hitting a golf ball (B) out of a sand trap. A disc (D) of predetermined diameter is placed on the top of the sand (S) with its leading edge either touching the underside of the golf ball or resting slightly behind it. When practicing a bunker shot, the golfer swings their club so it enters the sand immediately behind the trailing edge of the disc and passes through the sand beneath both the disc and the golf ball. The force imparted to the sand by the club causes the ball to fly out of the bunker on a cushion of sand. The disc provides an indication to the golfer as to how far behind the golf ball their club should enter the sand in order to hit the golf ball out of the sand trap.
