Abstract

The tricycle is steered, by the lateral inclination of the driver's body, of the main part formed by a wheel (A), a pedal gear (B) and a seat (C). The seat stays balanced at its top point by a flexible articulation (5) on a transverse structure supporting the rear wheels. The rear structure is held in the vertical and transverse support position by two lateral arms (4) forming a triangulation. Rubber connections join the different parts. Inclination of the driver's body causes a pendular movement of the cycle front (2). This generates a front steering movement by two sliding tubes (1) with circular movement with a progressive amplitude on the two rear wheels.

Description

La présente invention concerne un dispositif permettant à une personne en assise basse sur un tricycle à propulsion manuelle de provoquer une direction progressive par une action sur les trois roues du véhicule. Cette action se fait sous l'impulsion de la bascule du corps du conducteur s'opposant à la force centrifuge et entraînant un mouvement pendulaire de l'assise, transformé en mouvement progressif sur l'arrière, pour actionner les roues. The present invention relates to a device allowing a person in a low seat on a manual propelled tricycle to cause a progressive steering by an action on the three wheels of the vehicle. This action is done under the impulse of the rocker of the driver's body opposing the centrifugal force and causing a pendulum movement of the seat, transformed into progressive movement on the back, to actuate the wheels.

Le matériel actuellement sur le marché utilise deux formes de direction: - une par le pivotement du médalier (pédalier à mains), qui crée des problèmes de confort ergonomique et de perte d'efficacité dans l'action. Le médalier ne se trouve plus dans l'alignement du corps du conducteur. The equipment currently on the market uses two forms of steering: - one by the pivoting of the medal (hand crank), which creates problems of ergonomic comfort and loss of efficiency in action. The medal is no longer in alignment with the driver's body.

- une autre par un pivot situé sous le siège, qui permet d'orienter la roue avant solidaire du siège, mais qui a une trop grande sensibilité aux imperfections de la route et ne permet pas un braquage suffisant.- another by a pivot located under the seat, which makes it possible to orient the front wheel secured to the seat, but which is too sensitive to road imperfections and does not allow sufficient steering.

De plus ces deux formes de direction ne sont pas très sécurisantes par leur sensibilité en direction linéaire, et par l'instabilité dans les virages. In addition, these two forms of steering are not very reassuring by their sensitivity in linear direction, and by the instability when cornering.

Le dispositif selon l'invention permet de remédier à ces inconvénients ou de les diminuer. The device according to the invention makes it possible to remedy these drawbacks or to reduce them.

Les dessins annexés illustrent I'invention l'invention:
La figure 1 représente une vue en perspective éclatée de l'invention.The accompanying drawings illustrate the invention the invention:
Figure 1 shows an exploded perspective view of the invention.

La figure 2 représente une vue de côté de l'invention.Figure 2 shows a side view of the invention.

La figure 3 représente une vue de dessus éclatée pour mieux discerner la direction progressive (1).Figure 3 shows an exploded top view to better discern the progressive direction (1).

La figure 4 représente une étude de la direction progressive (1) en démontrant le principe du mouvement à amplitude progressive provoqué par le basculement de la poutre avant.Figure 4 represents a study of the progressive direction (1) by demonstrating the principle of the movement with progressive amplitude caused by the tilting of the front beam.

En référence à ces dessins, le dispositif comprend une partie principale appelée poutre avant faite de deux longerons plats (2) sur lesquels sont fixés la roue avant (A), le médalier (B) et le siège arrière (C). Cet ensemble repose sur le sol au niveau de la roue, et est fixé sur un point d'articulation (5) placé au haut de la structure transversale arrière (6). With reference to these drawings, the device comprises a main part called the front beam made of two flat beams (2) on which the front wheel (A), the medal (B) and the rear seat (C) are fixed. This assembly rests on the ground at the wheel, and is fixed on a hinge point (5) placed at the top of the rear transverse structure (6).

La structure arrière (6) est maintenue transversalement en position d'appui vertical par deux bras (4) fixés sur la poutre (2) au niveau de la roue (A) et à chaque extrémité latérale de la structure arrière (6). The rear structure (6) is held transversely in the vertical support position by two arms (4) fixed on the beam (2) at the wheel (A) and at each lateral end of the rear structure (6).

Les liaisons souples entre la poutre (2), la structure arrière (6), et les bras latéraux (4) sont en caoutchouc, réglables en dureté par compression pour permettre la liberté contrôlée du mouvement de bascule de la poutre (2).  The flexible connections between the beam (2), the rear structure (6), and the lateral arms (4) are made of rubber, adjustable in compression hardness to allow controlled freedom of the rocking movement of the beam (2).

Quand le conducteur bascule son corps dans le sens du changement de direction, afin de s'opposer à la force centrifuge qu'il va générer, il incline la poutre (2) sur laquelle il est solidaire. Le point d'articulation (5) étant situé derrière le haut du dossier du siège (C), la poutre (2) s'écarte de l'axe du tricycle dans un mouvement circulaire, et crée alors un mouvement de direction sur la roue avant en inclinant celle-ci. When the driver tilts his body in the direction of change of direction, in order to oppose the centrifugal force that he will generate, he inclines the beam (2) on which he is secured. The articulation point (5) being located behind the top of the seat back (C), the beam (2) moves away from the axis of the tricycle in a circular movement, and then creates a steering movement on the wheel before by tilting it.

Ce mouvement de la poutre est utilisé aussi de la base du siège en son point (R) en regard de la médiane de la structure arrière (6). Ce mouvement, étudié sur la FIG. 4, est transformé par un ensemble de deux tubes coulissants attachés par des liaisons souples d'une part à la partie basse arrière du siège pour le tube extérieur (X), d'autre part à la partie médiane de la structure arrière pour le tube intérieur (Y). Au repos, l'ensemble est en axe sur la position P 1. Quand la poutre bascule, le point (R) du siège en S 1 passe par les positions S2, S3, S4 et S5. Le tube extérieur (X) coulisse dans le tube intérieur (Y), et les points d'attache des biellettes de direction (8) passent par les positions P2, P3, P4 et P5. This movement of the beam is also used from the base of the seat at its point (R) opposite the median of the rear structure (6). This movement, studied in FIG. 4, is transformed by a set of two sliding tubes attached by flexible connections on the one hand to the lower rear part of the seat for the outer tube (X), on the other hand to the middle part of the rear structure for the tube interior (Y). At rest, the assembly is in axis on position P 1. When the beam tips, the point (R) of the seat in S 1 passes through positions S2, S3, S4 and S5. The outer tube (X) slides in the inner tube (Y), and the attachment points of the steering rods (8) pass through positions P2, P3, P4 and P5.

La FIG. 4 montre que l'extrémité du tube extérieur (X) en (R), en raison de son déplacement coulissant et circulaire, crée un mouvement à amplitude progressive sur les biellettes de direction (8) fixées à l'autre extrémité en (P). Les biellettes réglables transmettent le mouvement aux deux bras de direction (7) en (V). FIG. 4 shows that the end of the outer tube (X) at (R), due to its sliding and circular movement, creates a movement of progressive amplitude on the steering rods (8) fixed at the other end at (P) . The adjustable links transmit the movement to the two steering arms (7) at (V).

Le décalage angulaire des deux biellettes, créé lors du mouvement coulissant du tube (X), aligne les axes des roues en un seul centre (centre de rotation instantanée) pour éviter le ripage sur le sol. The angular offset of the two links, created during the sliding movement of the tube (X), aligns the axes of the wheels in a single center (instantaneous center of rotation) to avoid slipping on the ground.

La structure de base (poutre (2), structure arrière (6), bras latéraux (4) et repose pied (E)) est réalisée en plats d'aluminium marine, reliés entre eux par vissage sur des tubes légers. Le siège (C) est en polyester, et l'ensemble est modulable en fonction de la taille du conducteur. The basic structure (beam (2), rear structure (6), side arms (4) and footrest (E)) is made of marine aluminum plates, interconnected by screwing on light tubes. The seat (C) is made of polyester, and the assembly can be adjusted according to the size of the driver.

Selon une variante non illustrée, le même principe est utilisé pour des personnes utilisant la force des pieds. Dans ce cas, un pédalier traversant l'axe de la roue remplace le médalier (B). According to a variant not illustrated, the same principle is used for people using the force of the feet. In this case, a crankset crossing the axis of the wheel replaces the medal (B).

Ce dispositif selon l'invention est particulièrement destiné pour le modèle explicité aux personnes handicapées (entre autres paraplégiques), pour la variante aux personnes n'ayant pas d'équilibre, et pour toutes personnes désireuses de sensations nouvelles.  This device according to the invention is particularly intended for the model explained to disabled people (among others paraplegics), for the variant for people without balance, and for all people wishing for new sensations.
