Description

[0001] Mechanism for propelling human-powered vehicles by levers that pivot on a horizontal axis and / or two parallel and symmetrical vertical axes

[0002] Technical field to which the invention relates

[0003] The present invention relates to a mechanism that converts the alternating thrust of levers with the muscular force of the legs into a circular motion to propel land vehicles, sea vehicles, light aircraft, sports equipment, electric generators or anything that requires motive power.

[0004] Purpose of the invention

[0005] • Increase the vehicle's thrust, which reduces effort and increases its efficiency in terms of speed and time.

[0006] • Reduce the impact of fossil fuels on the economy and the environment.

[0007] • Allow light aircraft and gliders to fly without:

[0008] - Combustion engine.

[0009] - Electric motor and the necessary heavy batteries which increase the aircraft load.

[0010] - Towing by aircraft of gliders, cars or other means used in this field.

[0011] • Motivate individuals and groups to be physically active, which will benefit their health.

[0012] • Opening of a new field for land and aeronautical team sports. State of the prior art

[0013] There are many inventions for the propulsion of vehicles by human power, and the closest to the current invention, which falls under the international classification (B62M 1 / 30 and B62IVI 1 / 24), including the American document (US20070085297A1), and most of them are similar and close in terms of performance and content, and one of its most important disadvantages is that it depends only on a horizontal axis (HX) around which levers rotate, and which imposes a position that makes the vehicle raised and exposes it to strong air resistance that limits its effectiveness and requires the user to make an additional effort.

[0014] On the other hand, the present invention is characterized by the position of two parallel and symmetrical vertical axes (VX 1 and VX 2) where the user can be completely lying on his back or on his stomach, which reduces the height of the vehicle and thus weakens the air resistance facing the vehicle and its user, in order to provide better performance regarding the user's effort and improve the travel and flow of the vehicle.

[0015] Also, the present invention is distinguished from the previous one by the methods of collecting the driving forces of the users on a horizontal axis (HX) and / or two parallel and symmetrical vertical axes (VX 1 and VX 2).

[0046] Presentation of the invention and method of implementation

[0047] The present invention relates to a mechanism comprising a frame (10), levers (7), pedals (19, 17, 13), clutches (01), and / or freewheels, gears and / or pulleys, rotation shafts (8, 9, 11, 14, 15), and / or thrust shafts of the levers (20) which convert the reciprocating thrust movement into a rotational movement of the various land vehicles, marine vehicles, gliders, sports equipment, generators or anything that needs motive power, by the muscular effort of the legs of at least one user in a vertical position (standing) and / or a user in a horizontal position (sitting) or even completely lying on the back or stomach in order to push the levers (7) up and down and / or thrust forward which bounce back and forth less than half a turn around a horizontal axis (HX) and / or two parallel and symmetrical vertical axes (VX1 and VX2),(both axes *HX1 and HX2* can be inclined at an angle if required) where the levers (7) are coupled to the clutches (1) and / or the freewheels (not shown in the figures). In operation, they are held in the thrust stroke by at least one of the shafts (15,14,11,8) associated with the guide gears (2) and / or the pulleys (not shown in the figures) 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. The driving force is directed to the gearbox, the driving wheels, the propellers, etc., via chains, gears, shafts or belts, depending on the manufacturing requirements of the vehicle.,
