Abstract
A rowing apparatus having an elongate frame, a seat mounted for slidable displacement along that frame and a handle/cable arrangement fixedly mounted to an axle journaled in the frame. The cable being wrapped about a reel mounted on that axle causes a rotation of that axle in a first direction upon a given displacement. The axle is likewise fitted with a spring which is tensioned upon the axle's rotation in a first direction. Upon the storage of sufficeint energy in that spring, the spring effects a counter rotation of the axle to return the cable and its associated handle to its rest position. The axle is fitted with a flywheel, and a means adapted for applying a frictional drag force thereto. The drag means is adapted for controlling the resistance of the handle to displacement outwardly from the frame and further, for controlling the force by which the handle is urged restoringly back to its rest position.
