ABSTRACT:
A pivoting drive system for the application of rectilinear drive force, wherein the rectilinear force is converted to a rotational force. The apparatus employs a frame on which are mounted pedals for rectilinear motion. The pedals are linked with a cable linkage and when moved along rectilinear paths cause the cable linkage to move. The cable linkage is wrapped several times around dual wrap spools which turn as the cable linkage is moved. A unidirectional clutching mechanism incorporated with the wrap spools causes a pivot axis to rotate unidirectionally on rotation of the wrap spools. The pivot axis may be connected with a sprocket and drive chain assembly to provide propulsion force, for example, to a bicycle wheel.
