发明名称 Golf swing alignment device
摘要 A grid-like reference system for obtaining a properly aligned golf stance includes a plurality of lines and a plurality of frames for holding opposite ends of each line on the ground in a predetermined relationship. A stance position line is established which extends from in front of the golfer and under the golf ball to behind the golfer to reference placement of the golfer's heels. A toe alignment line is established substantially perpendicular to the stance position line as a reference for placement of the golfer's toes and, a pair of substantially parallel swing plane lines are established to straddle the golf ball to direct the swing of the golf club.
