TRICYCLE WITH PROPULSION CONTINUES MU BY THE GAME OF THE RAMEUR

摘要

The device of the invention can be used for reproducing the activity of person practicing rowing on a road or a track. The movement transmission during the forward travel is made by applying a pulling force on the oar (2); a cable (3) is mechanically attached to the oar (2) via a pulley (Y) and the cable (3) transmits the force towards the first chain (4); the latter transmits the force to the tooth sprocket (A) and drives the transmission axis and thus the rear wheel(s). The movement transmission during the return travel, when the oarsman comes back to the initial position, is made using a cable (8) mechanically connected to the seat on one end and to the second transmission end (6) on the other end. During the return travel of the oarsman, the pulling force applied on the foot board, due to the action of the folding legs, will drive the tooth sprocket B in the same manner. The propulsion of the tricycle is ensured by the successive pulling forces applied on both chains (4, 6) respectively installed on the tooth sprockets A and B. The inactive ends of the chains (4, 6), during the successive operation of sprockets A then B as free wheels, are connected by an elastic link (5) which is guided by the pulley Z.
