Mechanism for propelling human-powered vehicles by means of levers that pivot on a horizontal axis and/or two parallel and symmetrical vertical axes

A vehicle propulsion mechanism comprising:

• a chassis;
• levers,
• pedals;
• clutches and/or freewheels;
• gears and/or pulleys;
• rotation shafts;
• thrust shafts of the levers which convert the reciprocating thrust movement into a rotation movement of the various land vehicles, marine vehicles, gliders, sports equipment, generators or anything that needs driving force, by the muscular effort of the legs of at least one user in a vertical (standing) position and/or a user in a horizontal sitting position or even completely lying on their back or stomach in order to push the levers up and down and/or push forward which bounce back and forth less than half a turn around a horizontal axis (HX) and/or two vertical axes parallel and symmetrical (VX1 and VX2) (the two axes*HX1 and HX2* can be inclined at an angle if necessary) where the levers are coupled to the clutches and/or the freewheels, and in operation, they are maintained in thrust stroke by at least one of the shafts associated with the gears of the guide and/or pulleys or their substitute, but in the return stroke by means of a return spring, or its equivalent having no grip, which results in a continuous rotational movement in one direction, wherein the driving force is directed to the gearbox, drive wheels, propellers, etc., via chains, gears, shafts or belts, depending on the manufacturing needs of the vehicle.
