ABSTRACT:
A motor-less exercise treadmill including a main frame comprising a pair of spaced side-rail members having a bracket mounted transversely at a front end thereof, a U-shaped tubular rail mounted on the bracket having a grasp-rail and a pair of height adjustable front legs so as to permit the raising or lowering of the front end of the main frame, a generally rectangular platform support frame mounted substantially along the length and intermediate the side-rail members, a generally planar slider bed mounted on the platform support frame intermediate the side-rail members, a front and rear roller journaled transversely generally at the front and rear ends of the side-rail members, a pair of static rear legs substantially horizontally suspending the main frame from the floor surface, a first flywheel rigidly connected to the front roller and adapted to form a first pulley having a first end of an endless belt entrained thereabout, a second end of the belt entrained about a smaller diameter second pulley mounted forward of the first pulley on the frame and rigidly connected by an axle to a second flywheel, the first flywheel rotates at a speed determined by a user walking or running on the tread-belt, the first pulley to second pulley gear ratio causes the second flywheel to rotate at a faster speed than the first flywheel generating a centrifugal force transmitted rearwardly through the axle to the second pulley and through the drive belt to the first flywheel and front roller to impart a control to the momentary response of the tread-belt in relation to the user increasing or decreasing his or her walking or running speed thereon.
