Detailed description of a preferred embodiment of the invention

In accordance with the purpose of this invention, the tricycle for the movement and transport of a person is designed to displace a single person, with possibilities of sports and recreational use, and with comfort in the driving posture, protection against possible accidents, some outstanding dynamic qualities, and an advantage of the energy used for its displacement.

As can be seen in Figure 1, the tricycle (1) for the movement and transport of a person from the invention is constituted by a tubular frame (2) of lightweight material, which in addition to serving to hold the rest of components, completely surrounds the person conducting it, and It is also equipped with a safety belt (3), providing in this way protection in case of fall, collision or overturn.

This frame moves along the ground by three wheels, one front wheel (4) that is directional, and two rear wheels (5) and (6) by which the movement is transmitted from the pedals (7), through the corresponding wheels free (30,30 ') change plates (31) mounted freewheel envelopes double-acting, pinions (8) of the gearshift, located in the axle (8 '), through the corresponding free wheels (21.21 '), double cardan labels (22.22') and bearings (23.23 ').

As can also be seen in Figure 2, the axle height of the rear wheels and in the middle of them is located the seat (9), which is attached to the frame (2) by means of elastic bonding means (10) (in this preferred embodiment constituted by rubber studs) to improve the comfort of the march, and also on some rails (11) where you can move in the direction of the longitudinal axis (1 ') of the tricycle (1), to adjust its most suitable position for the user.

The three wheels (4), (5) and (6) have about brakes with independent control for each of them. The brake of the front wheel (4) is operated with either foot using the brake pedal (12), and the wheel brakes (5) and (6) backs are operated with each of the hands (13) to each of the corresponding hands. In this way, the user can help yourself in a controlled way, to keep the direction in curves and make acrobatic turns.

The pedals (7), instead of being the classics of full rotation, are "reciprocating", which are achieved important advantages

The longitudinal travel of each pedal (7) is only about 20 centimeters instead of the classic 35 centimeters in the case of complete rotation. Taking into account that the last centimeters of leg extension are where more strength can be done, it is possible to greatly improve the motor performance of the tricycle (1).

The path of those 20 centimeters of the pedal (7) It is effective in approximately 94% of it. However in the Classic bicycle, 35 centimeters only in a little more than fifty%.

In the case of the classic bicycle, the feet have of traveling a circumference of approximately 110 centimeters, while with this type of pedals (7) type "reciprocating" only they will have to perform a "reciprocating" movement of an arc Approximate 21 centimeters ("reciprocating" complete 42 centimeters) with which the effort that the user's muscles and joints is noticeably inferior in the model of the present invention than in the classic models.

Having this type of pedals (7), allows the user can pedal with total comfort, and even with a only foot (any of them), which is very useful in case of injury of any of the legs. Also allows of course pedal with both feet at once.

As can be seen in Figure 4, optionally, by a simple set of pulleys and cables (15) braided steel, the handlebar (14) can be enabled to also be able to reproduce the "reciprocating" movement of pedals (7) exercised by the user's feet, and therefore "pedal with your hands" if necessary, or even with all four limbs at the same time, like a paddle.

The rear wheels (5) and (6) can be found equipped with mechanisms (in this preferred embodiment constituted by two sliding bearings (23,23 '), two joints double cardan (22,22 '), two ball joints (5,25') and some levers (24)) which allow vascular in the upper axes (20,20 ') and so vary the angle of inclination, so that this increases the support base while lowering the center of gravity further of the tricycle set (1) and thus be able to achieve greater stability, as seen in figures 2 and 3.

The tricycle (1) of the invention can also have automatic orientation wheels (16) that help in the realization of "little horses" and other stunts, such and as seen in figure 6.

Additionally, it may also be endowed in the lower part of the seat (9) of an engine, a generator, a regulator and a battery (not shown), with which manages to accumulate the energy of the descents and braking, to return it in accelerations and climbs, in addition to using it for lighting and accessories.

Similarly, the tricycle (1) of the invention can also incorporate the following elements, accessories and benefits:

-

Windshield, sun and rain.

-

Wide fenders in all three wheels.

-

Angle variator with respect to ground, rear wheels, automatic.

-

Electric lighting.

-

March electric back

The invention shown may present the most relevant configuration and components for such functions. You can use the components that have been described or any other components suitable for performing the same type of purpose

The invention, within its essentiality, can be put into practice in other embodiments that differ only in detail from that indicated by way of example, at which will also achieve the protection sought. May, thus, this invention be carried out with the means, components and most suitable accessories, the component elements being able to be replaced by other technically equivalent ones, because everything remains this included in the claims.
