Vehicle operated by gravity in conjunction with other forces applied in parallel. The said vehicle is composed of the chassis seated onto 3 or 4 wheels (two big rear driving wheels and one or two front small driven wheels). At the inclined section of the chassis, the wheeled carriage is caused, uniquely, by the operator's weight to drive chains and ratchet gears. The previous gears rotate an element whereto another gear is connected transfering motion to another chain which operates another gear causing a connected-to-the-wheel shaft to move. The wheel carriage and the operator return upon propulsion of feet. If required, for greater speed, muscular force can be added to the existing mechanism. Thanks to its easy handling, said vehicle can be used as a transporting means, for riding, entertainment, and exercising purposes. Manufactured in various sizes, it can be employed by all ages, men and women. Free of wheels, it can be utilized for moving boats, pumping water or otherwise, as dictated. |
