Description

5 Technical field to which the invention relates The present invention relates to a mechanism that converts the reciprocating thrust of levers with the muscular force of the legs into a circular motion to 10 propel land vehicles, sea vehicles, light aircraft, sports equipment, electrical generators or anything that requires motive power. Purpose of the invention 15   • Increase the thrust of the vehicle, which reduces effort and increases its efficiency in terms of speed and time. • Reduce the consequences of fossil fuels on the economy and the environment. •Allow light aircraft and gliders to fly without: 20 - Combustion engine. - Electric motor and heavy batteries required which increase the load of the aircraft. - Towing of gliders by plane, car or other means used in this field. • Motivate individuals and groups to be physically active, which will benefit 25 their health. • Opening of a new field for land and aeronautical team sports. 2026204873   23 Jun 2026 State of the prior art There are many inventions for vehicle propulsion by human power, and the closest to the current invention, which falls under the international classification (B62M 1 / 30 and B62M 1 / 24), include the American document 5   (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 only depends on a horizontal axis (HX) around which levers rotate, and which imposes a position which makes the vehicle elevated and exposes it to strong air resistance which limits its efficiency and requires the user to make 10 additional effort. 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 the back or on the stomach, which reduces the height of the vehicle and thus weakens the air resistance facing the vehicle and its user, 15 in order to provide better performance regarding the user's effort and to improve the travel and flow of the vehicle. 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). 20 Brief description of the drawings Fig -1- Perspective view of the horizontal axis (HX) mechanism operated by a 25 single user.

In operation, they are maintained in thrust stroke by at least one of the shafts (15,14,11,8) associated with the gears of the guide (2) and / or pulleys (not shown in the figures) or their substitute, but in the 20 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, drive wheels, propellers, etc., via chains, gears, shafts or belts, depending on the manufacturing needs of the vehicle. 25 The accompanying figures and protective elements show some methods of manufacturing the mechanism for purposes of clarification, not restriction.
