ABSTRACT:
The invention concerns a sporting and exercise apparatus movable by muscular force including a frame having for the user an elongated platform supported by at least two wheels and a mechanical hand lever-drive for converting a lever motion into a rotary motion of at least one of the wheels. The lever drive has at least one hand lever hinged on the frame and having a toothed segment interconnecting a first and a second rotatable shaft each having a first and a second gear in which each first gear is supported on the shaft by free wheel units and in which a drive pinion is fixedly connected to the second shaft so that either forward or rearward movement of the hand lever will actuate one of the first gears and impart drive torque in the direction of movement of the apparatus while the other first gears torque is limited due to the action of the corresponding free wheel unit.
