Description

Cette présente invention est relative à un nouveau concept de fauteuilThis present invention relates to a new concept of chair

roulant léger à assistance électrique et économique en énergie, n'employant que des petites batteries pour le transport des personnes handicapées ou à mobilité réduite.  light-weight electric-powered and energy-efficient light-duty wheel, using only small batteries for the transport of disabled persons or persons with reduced mobility.

- Equipé d'éléments de commandes fixes à l'arrière, il est facile à conduire pour 5 l'accompagnateur. Doté d'un chassis entièrement pliable sans outils, il peut être transporté ou rangé sans difficultés. Des roues à bandages larges, souples et adhérentes permettent de rouler partout.  - Equipped with fixed controls in the back, it is easy to drive for the attendant. With a fully foldable frame without tools, it can be transported or stored without difficulties. Wheels with wide bandages, flexible and adherent allow to roll everywhere.

On connaît: - des fauteuils roulants, manuels, pliables, à roues étroites, que l'on doit généralement 10 pousser, et qui sont généralement très difficiles à manoeuvrer suivant la charge, la pente et l'état du terrain.  There are known: wheelchairs, manual, foldable, narrow-wheeled, which one must generally push, and which are generally very difficult to maneuver according to the load, the slope and the state of the ground.

- des fauteuils roulants électriques, peu ou non pliables, que seul le passager conduit par un joystick. Dans de rares cas, cette commande est amovible et installée à l'arrière. Ces fauteuils sont lourds, peu économiques en énergie d'où l'emploi de 15 grosses batteries, ils sont encombrants, peu transportables et coûteux. Ces deux versions de fauteuil ne peuvent rendre le même service que l'invention proposée puisque ce nouveau fauteuil roulant pliable à assistance électrique facilite la conduite pour l'accompagnateur, ce dernier n'ayant plus à pousser. De plus il est facile à ranger. Cette invention comble donc un besoin insatisfait dans la gamme actuelle 20 des fauteuils roulants pour le transport des handicapés, ou des personnes à mobilité réduite.  - electric wheelchairs, little or no folding, only the passenger driven by a joystick. In rare cases, this control is removable and installed at the back. These chairs are heavy, uneconomical energy from where the use of 15 large batteries, they are bulky, not transportable and expensive. These two chair versions can not provide the same service as the proposed invention since this new foldable electric wheelchair facilitates driving for the attendant, the latter no longer having to push. In addition it is easy to store. This invention thus fills an unsatisfied need in the current range of wheelchairs for the transport of handicapped persons, or persons with reduced mobility.

L'invention se différencie des autres fauteuils roulants électriques par une structure légère, articulée, entièrement pliable. II possède à l'arrière un guidon comportant des éléments de commandes fixes, freins et accélérateur. Des roues 25 larges, souples et adhérentes autorisent ce nouveau fauteuil à circuler sur des terrains non macadamisés, accidentés ou pentus, en toute sécurité. Pourvu d'une motorisation Hi-Tech' légère et économique en énergie d'où besoin que d'une petite batterie, il permet de véhiculer facilement et en tout confort des personnes handicapées ou à mobilité réduite sans effort pour l'accompagnateur.  The invention differs from other electric wheelchairs by a light structure, articulated, fully foldable. It has at the rear a handlebar with fixed control elements, brakes and accelerator. Wide, flexible and adherent wheels allow this new chair to circulate on non-tarmac, hilly or steep terrain, safely. Equipped with a Hi-Tech motorisation 'light and energy-saving, where only a small battery is needed, it can easily and comfortably transport people with disabilities or reduced mobility without effort for the guide.

Les dessins annexés (Figure 1) illustrent l'invention: En référence aux Figures (1) le chassis en forme de H (1) constitue la base principale de l'ensemble. Elle supporte le bloc moteur électrique, oscillant (2), les roues motrices (3), le tout régulées par l'amortisseur (4), une plaque (5) supporte la petite batterie (6), des roulettes (7) et le repose-pieds (8) .  The accompanying drawings (FIG. 1) illustrate the invention. Referring to FIGS. (1), the H-shaped frame (1) constitutes the main base of the assembly. It supports the electric motor unit, oscillating (2), the driving wheels (3), all regulated by the damper (4), a plate (5) supports the small battery (6), casters (7) and the footrest (8).

De part et d'autre du chassis (1), deux pattes (9) supportent la partie intermédiaire qui est composée de deux bras obliques (10) articulés dans les pattes (9). Le blocage en position oblique des deux bras (10) est fait automatiquement lorsque ceux-ci sont déployés en butée et par une action de poussée vers le bas; et 5 inversement vers le haut pour le déblocage. Ces deux bras obliques (10) supportent une assise (11) qui se trouve déportée vers l'avant, un dossier réglable (12) et deux accoudoirs (13). Deux autres bras (19) assurent la position horizontale de l'assise (11). Le blocage de ces deux bras s'effectue par un système de blocage par cames (21) qui vient s'agripper dans les pattes (20) en forme de crochets. A l'autre extrémité supérieure de ces bras (19) un poste de commande (14) comportant deux poignées (15) avec un frein (16) et un accélérateur-variateur (17). Sur le dessus, se trouve un témoin de décharge de la batterie (18). A l'intérieur de ce boitier (14) - non visible il y a une partie de l'électronique et le système de freinage de sécurité contre une mauvaise utilisation. L'ensemble du poste de commande (14) est articulé pour le réglage en hauteur, en fonction de la taille de l'accompagnateur. Le verrouillage dans la position choisie s'effectue par le système à cames (21).  On both sides of the frame (1), two lugs (9) support the intermediate portion which is composed of two oblique arms (10) articulated in the lugs (9). The locking in the oblique position of the two arms (10) is done automatically when they are deployed in abutment and by a pushing action downwards; and conversely upward for unlocking. These two oblique arms (10) support a seat (11) which is deported forward, an adjustable backrest (12) and two armrests (13). Two other arms (19) provide the horizontal position of the seat (11). The locking of these two arms is effected by a cam locking system (21) which is gripped in the tabs (20) in the form of hooks. At the other upper end of these arms (19) a control station (14) having two handles (15) with a brake (16) and an accelerator-variator (17). On top, there is a battery discharge indicator (18). Inside this box (14) - not visible there is a part of the electronics and the safety braking system against misuse. The entire control station (14) is articulated for height adjustment, depending on the size of the attendant. The locking in the chosen position is effected by the cam system (21).

La figure 3 illustre le fauteuil entièrement replié.  Figure 3 illustrates the fully folded chair.

Figuré par les flèches, les possibilités de réglage de l'inclinaison du dossier (12), du cale-pieds (8), et de son inclinaison.  Figured by the arrows, the possibilities of adjusting the inclination of the backrest (12), the footrest (8), and its inclination.

L'entrainement du fauteuil roulant est fait par un moteur électrique, à l'intérieur du bloc (2), régulé par une électronique, couplé à un boitier réducteur de vitesse. A la sortie du boitier, un arbre en prise directe entraine les deux roues motrices (3) à bandages 25 larges, souples et adhérents qui absorbent les imperfections du terrain et permettent de rouler partout. A l'intérieur de ces deux roues (3), un différentiel autorise une rotation facile à 360 du fauteuil. La plaque (5) sur le chassis (1) reçoit la batterie d'alimentation du moteur, légère et rechargeable.  The training of the wheelchair is done by an electric motor, inside the block (2), regulated by an electronic, coupled to a gearbox gearbox. At the exit of the housing, a direct drive shaft drives the two drive wheels (3) 25 broad bandages, flexible and adherent that absorb the imperfections of the terrain and allow to drive everywhere. Inside these two wheels (3), a differential allows easy rotation to 360 of the chair. The plate (5) on the chassis (1) receives the engine power battery, light and rechargeable.

Le réglage de la vitesse est obtenue par l'accélérateur-variateur de commande (17) 30 qui se trouve sur le guidon du fauteuil. Une poignée de frein actionne deux freins à disques hydrauliques (23).  Speed adjustment is achieved by the throttle control (17) 30 located on the wheelchair handlebars. A brake handle operates two hydraulic disc brakes (23).

Selon une variante non illustrée, un rupteur mécanique agissant directement sur les freins permet au fauteuil de stopper en cas de mauvaise manipulation.  According to a variant not shown, a mechanical switch acting directly on the brakes allows the chair to stop in case of mishandling.

Dans le cadre de cette invention, de nombreuses améliorations peuvent être 35 apportées à ce nouveau concept de fauteuil.  In the context of this invention, many improvements can be made to this new chair concept.
