ABSTRACT:
A versatile swing training machine for developing muscular strength and coordination to perform athletic swings typical of baseball, golf, hockey, or tennis. A drive arm pivotably carried on a frame is engaged and forcibly driven in rotation by a partially guided hand-held swing implement, against a variable resistance developed by a resistance element and imparted through a linkage mechanism. The resistance element may include a fluid damping device and a mechanical spring, which also assists the return swing of the drive arm. The linkage mechanism transmits linearly developed resistance and translates it to torsional resistance on the drive arm, equally for right and left-handed swings. Optimum training resistance is gradually maximized through the acceleration zone of the swing and tapers off during the followthrough, being effective for the full forward swing. The backswing is relatively unresisted. Adjustments accommodate various swing positions as well as individual differences in height and reach.
