In the field of the muscular propulsion vehicles different means of transport are known, the motion of whose is given to the action of the limbs onto mechanical devices. In particular pedal devices are known, as for instance the bicycles or similar, in which the push action is alternatively given to a limb or to the other with periodic action. The push to determine the propulsion is generally determined to the action on the pedal of the muscular force of stretching of a leg, with push action distributed over a circumference arc described to the motion of the pedal. This modality of working determines, however, a partial exploitation of the potential of the muscular force of the transport means user, such as is provided the action given alternatively to a single leg. Moreover, the push action in the known means is actuated only onto a circumference arc of the motion transmission device to the kinematic chain.
Subject-matter of the invention is a new vehicle able to better exploit the use of the muscular force of the user of the device to produce the motion, with contemporary use of the legs and of the arms and having propulsion push action and traction distributed onto all the circumference of the mechanism determining the circular motion. Other aim reaches to the invention is to have a vehicle that use simultaneously more muscular groups, with advantages for the harmonic development of the muscular masses take up in the motion. Further aim reaches to the invention is to have a vehicle with practical and comfortable use, able to reach good speed of march.
Further characteristics and advantages of the invention will be better understood from the following description of a preferred embodiment but not exclusive also illustrated in an indicative and not limiting way in the drawings of sheets 1, 2 and 3. In particular in sheet 1
The vehicle with contemporary stretching and contraction action of the lower and upper limbs consists of a mechanism 1 equipped with a connecting rod 2 connected at one of its end with a seat 3 by a pin 4 and support fork of the pin 5, fixed in the outside back part of the seat. At the other end of the connecting rod 2 is connected, by a pin 6, a plate 7. Said plate 7 rotates around a central pin 8. On the same pin rotates and is fixed integral with the plate 7 a crown wheel 9 connected, by chain 10, to a sprocket-wheel 11 with free wheel device 12 and to the back driving wheels. The central pin 8 and the pin 13 of the sprocket-wheel 11 are supported onto a frame 14 positioned onto four wheels. The crown wheel 9, the sprocket-wheel 11 and the chain 10 can to be realized like a transmission, i.e. with more crowns and different sprocket-wheels, on the base of the known art and to be realized to a man skilled in the art. The seat 3 is put onto a slide 15 placed onto guides 16 inside the frame 14 of the vehicle. The guides 16 can be equipped with bearings 17 to make easy the sliding onto the guides.
The seat 3 is, moreover, equipped with a belt 18 to stop the user body at the back of the seat 3. Onto the frame 14 is present, moreover, a toe-clip device 19, to be regulated on the base of the sizes of the legs of the user at the maximum stretching. In the same manner is present onto the invented vehicle a driving device 20 to drive the front wheels to be regulated on the base of maximum extension of the arms. Reserve devices, like the braking device, lighting devices, the direction devices and others to complete the vehicle are arranged on the base of the technics known the art and are easily actuated to a man skilled in the art. In working phase the vehicle provides the contemporary push of arms and legs with stretching of these and the sliding of the seat 3 from the advanced position to the backward position in the way of the back wheels.
The translation motion of the seat 3 is transmitted by the connecting rod 2 to the plate 7 determining its rotation. The crown wheel 9, jointed with the plate 7, is so also it puts in rotation and it transmits the motion by the chain 10 to the sprocket-wheel 11 and to the back driving wheels determining the going on of the vehicle. At the end of stroke of the slide 15 and at the outside dead point of the plate 7 the contraction phase of the limbs begins. The vehicle user by the toe-clip device 19 and the driving device 20 determines the advancement of the slide 15 in opposite way at the motion of the going, with the motion of the seat 3 making easy in the dragging movement in this phase of the of the belt 18.
With the return of the seat in the in initial position the connecting rod 2 drags the plate 7 making complete the rotation and transmitting the motion to the back wheels also in this phase. Periodically repeating the motion with the stretching and the contraction of the limbs the translation motion of the seat is determined in one way and in the other one. This movement is transformed in rotation and in advancement of the vehicle. In the phases in which no push or contraction are actuated to the user and consequently the seat 3 is not moved, the free wheel device 12 permits the motion continuity. The invented device may, of course, be realized in similar embodiments with three or two wheels, having however in these cases less stability. The invented subject-matter has, moreover, the possibility to be used like gymnastic apparatus simply changing the driving wheels with gear wheels for going resistance. The invented subject-matter so created is possible of a lot of modifications and variations, all part of the present inventive concept. All the details, moreover, are to be changed with other technically equivalent.
