Abstract

A lifting device (A) vertically displaces a support (6) for an articulated arm (7,12) with a platform (10,11) mounted at the free end. The lifting device is in the form of a screw (1) driven in rotation by an electric motor/reduction gear unit (4,5). The arm carrying the platform is articulated to permit the platform to be swung across the doorway when it is in the raised position. Once in the lowering position the arm is trapped in guides to prevent rotation. Control facilities comprising control switches and limit switches are accessible either from the vehicle or from the lift itself. A guide (15) in the floor of the vehicle controls the motion of the platform inside the vehicle. The platform is equipped with an anchoring device.

Description

La présente invention concerne un nouveau dispositif destiné à être monté sur des véhicules pour permettre le levage de charges diverses, notamment de fauteuils roulants de handicapés. The present invention relates to a new device intended to be mounted on vehicles to allow the lifting of various loads, in particular wheelchairs for the disabled.

De par sa réalisation, le dispositif de l'invention n'a pas besoin d'être adapté à un type de fauteuil particulier et il peut être utilisé aussi pour des personnes à faible mobilité qui autrement ne pourraient pas monter ni descendre sans grande difficulté d'un véhicule. By virtue of its embodiment, the device of the invention does not need to be adapted to a particular type of chair and it can also be used for people with low mobility who otherwise could not get on or off without great difficulty. 'a vehicle.

Le dispositif de l'invention permet aussi la manutention de charges diverses, et en outre, il peut facilement être escamoté lorsqu'il n'est pas utilisé. The device of the invention also allows the handling of various loads, and in addition, it can easily be retracted when not in use.

Conformément à l'invention, le dispositif de levage, notamment de fauteuils de handicapés et autres charges, sur véhicules, comporte près d'une ouverture de porte du véhicule un vérin pour le déplacement vertical d'une pièce de support d'un bras articulé au moins en deux parties à l'extrémité libre duquel est montée une plate-forme. According to the invention, the lifting device, in particular for wheelchairs for the disabled and other loads, on vehicles, comprises, near a door opening of the vehicle, a jack for the vertical movement of a support piece of an articulated arm. at least in two parts at the free end of which is mounted a platform.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit. Various other characteristics of the invention will also emerge from the detailed description which follows.

Une forme de réalisation de l'objet de l'invention est représentée, à titre d'exemple non limitatif, au dessin annexé. An embodiment of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawing.

La fig-. 1 est une perspective schématique en partie éclatée du dispositif de l'invention. The fig-. 1 is a partially exploded schematic perspective of the device of the invention.

La fig. 2 est une perspective, analogue à la fig. 1, lorsque le dispositif est escamoté. Fig. 2 is a perspective, similar to FIG. 1, when the device is retracted.

Le dispositif comporte une vis 1 montée sur le panneau de côté A du véhicule par un palier 2 et sur le plancher par une crapaudine 3. La vis 1 est mise en rotation par un moto-réducteur électrique 4 par l'intermédiaire d'un renvoi d'angle 5. Un écrou 6 solidaire d'un bras articulé 7 est monté sur la vis. L'écrou ne peut tourner qu'en partie supérieure de la vis grâce à un guidage 8 constitué par exemple par une tige ou une rainure suivie par un doigt non représenté. The device comprises a screw 1 mounted on the side panel A of the vehicle by a bearing 2 and on the floor by a clamp 3. The screw 1 is rotated by an electric gear motor 4 via a reference angle 5. A nut 6 secured to an articulated arm 7 is mounted on the screw. The nut can only rotate in the upper part of the screw thanks to a guide 8 constituted for example by a rod or a groove followed by a finger not shown.

A l'extrémité du bras est disposée une plateforme 9 munie de rebords basculants 10 et d'un dispositif d'arrimage 11. L'àssemblage est constitué par une noix 12 et une tige cylindrique 13 permettant la rotation plate-forme/bras et la descente du bras lorsque la plate-forme repose sur le plancher. Les mouvements bras/caisse et plate-forme/bras sont limités par des butées non représentées. At the end of the arm is disposed a platform 9 provided with tilting flanges 10 and a lashing device 11. The assembly consists of a nut 12 and a cylindrical rod 13 allowing the platform / arm rotation and the lowering of the arm when the platform rests on the floor. Arm / body and platform / arm movements are limited by stops not shown.

Enfin, les mouvements de la plate-forme sont guidés par deux doigts 14 solidaires de cette dernière se déplaçant dans un rail 15 solidaire du plancher. Finally, the movements of the platform are guided by two fingers 14 integral with the latter moving in a rail 15 integral with the floor.

Une rambarde repliable 16 permet à une personne à mobilité réduite de se maintenir sur la plate-forme, lors de la montée à l'intérieur du véhicule. A folding guardrail 16 allows a person with reduced mobility to remain on the platform when climbing inside the vehicle.

L'ensemble vis 1, écrou6, moto-réducteur 4 est renfermé dans un boîtier 18 qui est avantageusement percé d'un trou 19 pour le passage d'une manivelle 17 permettant la commande du renvoi d'angle 5 d-c de la vis t en cas de panne du moteur 4. The set of screws 1, nut 6, gear motor 4 is enclosed in a housing 18 which is advantageously pierced with a hole 19 for the passage of a crank 17 allowing the control of the bevel gear 5 dc of the screw t in engine failure 4.

Comme l'illustre la fig. 2 en position escamotée, le bras 7 se trouve sous l'assise 21 d'un siège repliable qui peut être relevé comme montré par la fig. 1. Dans cette position, la plate-forme 9 repose sur le plancher du véhicule, les rebordsbasculants 10 étant disposés à plat ou éventuellement insérés dans une trappe. As illustrated in fig. 2 in the retracted position, the arm 7 is located under the seat 21 of a folding seat which can be raised as shown in FIG. 1. In this position, the platform 9 rests on the vehicle floor, the tilting edges 10 being arranged flat or possibly inserted in a hatch.

Lorsqu'il y a lieu d'utiliser le dispositif de levage le moteur 4 est actionné pour que l'écrou 6 soit amené dans la position haute représentée à la fig. 1. Cela a pour effet de soulever la plate-forme 9. On fait alors pivoter l'écrou 6 dans le sens pour lequel la plate-forme 9 est amenée à l'extérieur de l'ouverture de porte 22. On actionne à nouveau le moto-réducteur 4 pour faire descendre la plate-forme jusqu'au sol, ce qui permet de mettre en place une charge sur la plate-forme par exemple une chaise roulante a d'un handicapé.  When it is necessary to use the lifting device, the motor 4 is actuated so that the nut 6 is brought into the high position shown in FIG. 1. This has the effect of lifting the platform 9. The nut 6 is then pivoted in the direction for which the platform 9 is brought outside the door opening 22. It is actuated again the gear motor 4 to lower the platform to the ground, which allows to put a load on the platform for example a wheelchair has a disabled.

Cette chaise roulante est immobilisée au moyen du dispositif d'arrimage 11 et les rebords basculants 10 sont relevés pour empêcher tout déplacement de la chaise roulante ou autre charge. Le moto-réducteur 4 est ensuite de nouveau actionné de sorte que le bras 7 soulève la charge jusqu'au dessus du plancher du véhicule pour permettre l'introduction des doigts de guidage 14 dans le rail 15. This wheelchair is immobilized by means of the securing device 11 and the tilting edges 10 are raised to prevent any movement of the wheelchair or other load. The gear motor 4 is then actuated again so that the arm 7 lifts the load up to the top of the vehicle floor to allow the introduction of the guide fingers 14 into the rail 15.

Bien que cela ne soit pas représenté, les rebords articulés 10 sont munis de verrous pour les maintenir en position relevée, et ces verrous comportent des détecteurs de position, par exemple des micro-contacts électriques qui interdisent toute manoeuvre du moto-réducteur 4 tant qu'ils ne sont pas en position relevée alors que la plateforme est sortie du véhicule. D'autres organes de sécurité sont également prévus pour empêcher le démarrage du véhicule lorsque la plate-forme est sortie ou pour empêcher le fonctionnement du dispositif si le frein de stationnement du véhicule n'est pas serré. Although this is not shown, the hinged edges 10 are provided with latches to keep them in the raised position, and these latches include position detectors, for example electrical micro-contacts which prohibit any operation of the gear motor 4 as long as '' they are not in the raised position while the platform is out of the vehicle. Other safety devices are also provided to prevent the vehicle from starting when the platform is out or to prevent the device from operating if the vehicle's parking brake is not applied.

L'invention n'est pas limitée à l'exemple de réalisation, représenté et décrit en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre.  The invention is not limited to the embodiment, shown and described in detail, because various modifications can be made without departing from its scope.
