Abstract

The subject of the invention relates to a lifting apparatus for a handicapped wheelchair or the like. It consists of the combination of a double-action jack 4 moved hydraulically, whose rod 6 is connected to endless chains 7, 7% which are parallel and engage on toothed wheels 8, 8%, 9, 9% whose shaft 14 drives a radially implanted arm 15, at the end of which is mounted the pivoting carrying element of the chair 16. It is intended to allow progressive immersion and raising of a chair supporting a handicapped person or to allow him to reach planes of different levels.

Description

L'objet de l'invention concerne un appareil de levage pour fauteuil d'handicapé ou similaire. The object of the invention relates to a lifting device for a disabled person's chair or the like.

Il est destiné à permettre l'immersion progressive et le relèvement d'un fauteuil supportant un handicapé ou de lui faire atteindre des plans de niveaux différents. It is intended to allow the progressive immersion and the raising of a wheelchair supporting a handicapped person or to make him reach plans of different levels.

Il existe divers appareillages par treuils ou encore par câbles pour permettre une immersion progressive à des profondeurs diverses d'un handicapé ou malade sans quitter son siège ou son brancard, mais ces dipositifs sont complexes, d'un encombrement important et d'une maniabilité difficile. There are various devices by winches or cables to allow progressive immersion at various depths of a disabled or sick person without leaving their seat or stretcher, but these devices are complex, of considerable bulk and difficult to handle .

Le dispositif suivant l'invention supprime ces inconvénients et permet avec un mécanisme simplifié et fiable, d'un encombrement réduit d'assurer l'immersion ou le relevage d'un siège plongé dans une piscine. The device according to the invention eliminates these drawbacks and allows, with a simplified and reliable mechanism, a reduced size to ensure the immersion or the lifting of a seat immersed in a swimming pool.

Il est constitué par la combinaison d'un vérin à double effet mû hydrauliquement, dont la tige est reliée à des chaînes sans fin paralléles se crantant sur des roues dentées dont l'arbre entra?ne un bras radialement implanté à l'extrémité du quel est monté l'élément porteur tourillonnant du fauteuil. It is made up of a combination of a hydraulically-driven double-acting cylinder, the rod of which is connected to parallel endless chains, notched on toothed wheels, the shaft of which drives an arm radially implanted at the end of which is mounted the swiveling support element of the chair.

Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des forme de réalisation de l'objet de l'invention
La figure 1 est une vue d'ensemble vu en élévation et en coupe du dispositif de levage.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 is an overall view in elevation and in section of the lifting device.

Les figures 2, 3, 4 représentent le fauteuil de levage mû mécaniquement. Figures 2, 3, 4 show the mechanically driven lifting chair.

Les figures 5, 6 montrent schématiquement vu en élévation en en plan le mécanisme d'entraînement. Figures 5, 6 schematically show in plan elevation the drive mechanism.

La figure 7 est une vue en perspective du dispositif utilisable pour le levage des brancards. Figure 7 is a perspective view of the device used for lifting stretchers.

L'appareil est constitué par un chassis 1 monté sur organe- de roulement 2 avec tiges d'ancrage 3 évitant son déplacement lorsqu'il est sur son aire d'utilisation.  The device consists of a chassis 1 mounted on the rolling member 2 with anchor rods 3 preventing it from moving when it is in its area of use.

Il comporte un vérin ou cylindre 4 avec piston 5 dont la tige 6 formant vérin est reliée aux chaînes sans fin 7, s7" se crantant sur les roues dentées 8, 9, 8', 9'. It comprises a jack or cylinder 4 with piston 5, the rod 6 of which forms a jack is connected to the endless chains 7, s7 "which are notched on the toothed wheels 8, 9, 8 ', 9'.

Ce piston 5 est actionné par un fluide telle de 1 'eau
Ce fluide est amené par la canalisation 10 dans la vanne à 8 voies 12. L'évacuation s'effectue par la canalisation 11 dans le collecteur 13.This piston 5 is actuated by a fluid such as water
This fluid is brought through line 10 into the 8-way valve 12. Evacuation takes place through line 11 into the manifold 13.

La tige 6 du vérin actionne 1' engrenage -8 dont l'arbre 14 entraine le bras de levage 15. Les engrenages 8, B" sont reliés par l'arbre 14, et les engrenages 9, 9' sont relies par l'arbre 19. La tête de la tige 6 du piston comporte un arbre 18 qui est relié aux chaines 7, 7'. The rod 6 of the actuator actuates the gear -8 whose shaft 14 drives the lifting arm 15. The gears 8, B "are connected by the shaft 14, and the gears 9, 9 'are connected by the shaft 19. The head of the piston rod 6 has a shaft 18 which is connected to the chains 7, 7 '.

Le circuit hydraulique peut être à basse pression. The hydraulic circuit can be at low pressure.

Il agit sur le piston 5 qui se déplace dans le corps- -du -venn 4 qui, vu ses dimensions, lui permet de développer une grande puissance.It acts on the piston 5 which moves in the body-of the -venn 4 which, given its dimensions, allows it to develop great power.

Le bras 15, qui porte le siège 16, pivote sur angle de très grande amplitude. The arm 15, which carries the seat 16, pivots on a very large angle.

Pour éviter le balancement du siège 15 on ;tLre une liaison par chaine entre l'axe qui porte le siège et l'axe de pivotement au bras. To prevent the seat 15 from rocking, tLre a chain link between the axis carrying the seat and the pivot axis on the arm.

Le levier 17 qui commande l'appareil actionne la van- ne à quatre voies 12, ce qui permet d'alimenter suivant sa posi- tion, soit un côté du piston 11, soit l'autre par le conduit 20
Le levier commande la vanne 12 et permet suivant sa position d'alimenter, soit une face, soit l'autre au piston à double effet. En position médiane l'appareil s'arrete de fonc- tionner. Il reprend sa marche à nouveau suivant qu'on veut monter ou descendre.The lever 17 which controls the apparatus actuates the four-way valve 12, which makes it possible to supply, depending on its position, either one side of the piston 11 or the other via the conduit 20
The lever controls the valve 12 and allows, depending on its position, to supply either one face or the other to the double-acting piston. In the middle position, the device stops operating. It resumes walking again depending on whether you want to go up or down.

L'opérateur qui assure la manoeuvre est toujours maître de la situation. The operator who ensures the maneuver is always in control of the situation.

Le même entrainement, figure 7, peut être utilise mur 1 t immersion des brancards dans une piscine ou similaire A -tet effet, le bras moteur 21 est relié au bras porteur 22 par une monture rigide 23 suspendue librement aux points 24, 25.L'arbre 26 transmet le mouvement de rotation du bras 21 au bras 22. The same drive, FIG. 7, can be used wall 1 t immersion of the stretchers in a swimming pool or the like For this purpose, the driving arm 21 is connected to the carrying arm 22 by a rigid frame 23 suspended freely at points 24, 25.L the shaft 26 transmits the rotational movement from the arm 21 to the arm 22.

Cette plate-forme 23 peut supporter un brancard ou tout autre ustensile approprié. This platform 23 can support a stretcher or any other suitable utensil.

Sous l'action du vérin L, la chaine 7, 7' est entra;-
née et fait tourner le bras 15 à couple constant. L'angle de rota
tion décrit par le bras 15 est fonction du diamètre des engre
nages 8, 8', 9, 9', et- de la course de la tige 6 du vérin.Under the action of the jack L, the chain 7, 7 'is entered; -
born and rotates arm 15 at constant torque. The angle of rota
tion described by the arm 15 is a function of the diameter of the gear
strokes 8, 8 ', 9, 9', and- of the stroke of the rod 6 of the jack.

Le rotation du bras 15 est supérieure à 900 et peut
dépasser 1800.The rotation of the arm 15 is greater than 900 and can
exceed 1800.

Toutefois les formes, dimensions et dispositions des
différents éléments, pourront varier dans la limite des équiva
lents, comme d'ailleurs les matières utilisées pour leur fabri
cation, sans changer pour cela, la conception générale de l'in
vention qui vient d'être décrite. However the forms, dimensions and arrangements of
different elements, may vary within the limit of equivalents
slow, like the materials used to make them
cation, without changing for that, the general conception of the in
vention which has just been described.
