Description

FAUTEUIL ELECTRIQUE POUR LE TRANSPORT DES HANDICAPES PAR UN ACCOMPAGNATEUR ELECTRIC ARMCHAIR FOR THE TRANSPORT OF DISABLED PERSONS BY AN ACCOMPANIATOR
Cette présente invention est relative à un nouveau concept de fauteuil roulant électrique pour le transport des personnes handicapées par un accompagnateur.This present invention relates to a new concept of electric wheelchair for the transportation of disabled persons by an attendant.
Equipé d'éléments de commandes fixes à l'arrière pour la conduite par un accompagnateur. Entièrement pliable et dépliable sans outils, il peut être transporté ou 5 rangé sans difficultés. Doté d'un châssis articulé, il comporte en outre un système d'amortisseur.Equipped with fixed controls at the rear for driving by an attendant. Completely foldable and unfoldable without tools, it can be transported or stored without difficulty. Equipped with an articulated frame, it also comprises a damper system.
On connaît :We know :
- des fauteuils roulants électriques pour le transport des personnes handicapées par un accompagnateur, pas ou peu facilement pliables. Ces fauteuils sont encombrants, 10 lourds et ne comportent pas de système d'amortisseur. Ils sont peu transportables et, de part leur complexité, ils sont coûteux.- electric wheelchairs for the transport of disabled people by an attendant, not or not easily foldable. These chairs are bulky, heavy and do not have a damper system. They are not very transportable and, because of their complexity, they are expensive.
L'invention se différencie des autres fauteuils roulants électriques par une structure articulée, simple et entièrement pliable. Sa base en forme de H permet de recevoir à l'avant deux roulettes, un repose-pieds escamotable et réglable, au milieu une petite 15 batterie et à l'arrière un bloc moteur oscillant comportant un amortisseur. La partie supérieure de cette base, qui supporte le siège, est maintenue par deux bras de force obliques encaissant la charge principale avec un cadre supérieur comportant des éléments de verrouillage, à l'extrémité de ce cadre se situent les poignées de commandes.The invention differs from other electric wheelchairs by an articulated structure, simple and fully foldable. Its H-shaped base allows to receive at the front two wheels, a retractable and adjustable footrest, in the middle a small battery and at the rear an oscillating engine block comprising a damper. The upper part of this base, which supports the seat, is held by two oblique force arms encasing the main load with an upper frame having locking elements, at the end of this frame are the control handles.
20 Ce fauteuil est facile à plier et ranger. Il offre aussi une structure solide ne se dégradant pas par des pliages et des dépliages intensifs. Il est capable, par son système, de supporter de lourdes charges. Son équilibre et sa stabilité sont optimum en raison d'une base offrant un centre de gravité très bas. Il comble donc un besoin insatisfait dans la gamme des fauteuils existants pour le transport des personnes 25 handicapées ou des personnes à mobilité réduite. Les dessins annexés (Figure 1) illustrent l'invention :20 This chair is easy to fold and store. It also offers a solid structure that does not degrade by intensive folding and unfolding. It is able, by its system, to support heavy loads. Its balance and stability are optimum because of a base with a very low center of gravity. It therefore fills an unmet need in the range of existing wheelchairs for the transport of persons with disabilities or persons with reduced mobility. The appended drawings (FIG. 1) illustrate the invention:
En référence aux Figures (1) le châssis 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), 30 des roulettes (7) et le repose-pieds (8). De part et d'autre du châssis (1), deux pattes (9) supportent la partie intermédiaire qui est composée de deux bras de force (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 de force (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 10 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 15 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 ).With reference to Figures (1), the H-shaped frame (1) constitutes the main base of the assembly. It supports the electric motor unit, oscillating (2), the drive wheels (3), all regulated by the damper (4), a plate (5) supports the small battery (6), wheels (7) and the footrest (8). On either side of the frame (1), two lugs (9) support the intermediate portion which is composed of two 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 arms of force (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 hinged 15 for height adjustment, depending on the size of the attendant. The locking in the chosen position is effected by the cam system (21).

L'entraînement 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 de ce boitier, un arbre en prise directe entraîne 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 châssis (1) reçoit la batterie d'alimentation du moteur, légère et rechargeable.The wheelchair drive is done by an electric motor, inside the block (2), controlled by an electronic, coupled to a speed reduction gearbox. At the exit of this 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 can roll 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 obtenu par l'accélérateur-variateur de commande (17) 30 qui se trouve sur le guidon du fauteuil. Une poignée de frein actionne deux freins (23).The speed setting is achieved by the control throttle (17) 30 located on the wheelchair handlebars. A brake handle operates two brakes (23).
