  • Patent number: 5188367
    Abstract: A generally rigid golf club suspension rod rotatably suspends a golf club head by a universal connector. Rotation of the rigid rod is transmitted through a knuckle to a circular gear mounted for rotation about a substantially horizontal axis. The circular gear is supported on a carriage for movement longitudinally of a horizontally disposed housing and the circular gear is in mesh with a longitudinally extending fixed rack such that swinging of the golf club and rotation of the suspension rod drives the carriage to the left or right in the direction of the swing path of the golf club depending upon whether the player is in the back swing or the fore swing. The universal connector gives a normal feel to the player handling the golf club, and the longitudinal movement of the carriage provides realistic elliptical swing paths for the golf club head in the backward and forward swings of the golf club.
