发明名称 Golf club swing alignment device
摘要 A device for providing visual feedback to the golf player of his grip during his golf stroke in maintaining proper alignment of the golf club face and the golf ball while increasing the air resistance the player encounters during the golf stroke. The device comprises a finned member for securement to the shaft of a conventional golf club adjacent the head. Certain of the fins include surfaces having visually perceptible indicia thereon, e.g., colors. The device is arranged so that one of the fins is oriented in a direction whereupon certain indicia are not visible if the club head is in a desired orientation, but will be visible if the club head is in another orientation, e.g., open or closed. The fins provide wind resistance during the swing. A weight may be secured to one of the fins.
