Abstract
A wind-drag type exercise rowing unit includes a generally horizontally extending frame on which a wind-drag type flywheel is mounted. A seat and a foot rest unit are fixed on the frame for supporting an operator. A large belt pulley is mounted on the frame and connected to a rope sheave by means of a one-way clutch. An endless belt is carried on the large belt pulley and a small belt pulley which is secured to the flywheel. A rope is wound around the sheave and secured to the same at one end to a handle at the other end. When the handle is pulled away from the sheave, the sheave is rotated in a direction which causes the clutch to unlock the large belt pulley from the sheave. When the rope is released, the sheave is returned to its static position by a spiral spring. The return rotation of the sheave causes the large belt pulley to be locked on the sheave so that the large belt pulley rotates synchronously with the sheave, thereby driving the small belt pulley and the flywheel. The higher the rotational speed of the flywheel, the greater the air resistance encountered by the fan-type blades of the flywheel. As a result, the rotation of the sheave can be transferred smoothly and quietly to the flywheel by means of the belt and the belt pulleys.
