Description

La présente invention a pour objet un dispositif de mise en position d'une personne notamment d'une personne handicapée.The present invention relates to a device for positioning a person, in particular a disabled person.

Les personnes handicapées, par exemple à la suite d'accidents cardio-vasculaires, sont excessivement dépendantes et les moyens mis à leur disposition pour les rendre un peu plus autonomes sont peu nombreux.People with disabilities, for example following cardiovascular accidents, are excessively dependent and there are few means available to them to make them a little more independent.

On connait des fauteuils qui ont une assise mobile entre deux positions l'une dans laquelle la personne est assise et l'autre dans laquelle elle est quasiment en position debout.Armchairs are known which have a movable seat between two positions, one in which the person is seated and the other in which he is almost in a standing position.

Ce type de fauteuil médical ne permet aucune variante puisque le dossier est fixe par rapport à l'assise. Notamment, il n'est pas possible de réaliser un plan de couchage or chacun sait que la position assise est quand même une position fatigante.This type of medical chair does not allow any variation since the backrest is fixed relative to the seat. In particular, it is not possible to make a sleeping plan, but everyone knows that the sitting position is still a tiring position.

Aussi faut-il une aide de façon continue à la disposition de l'handicapé ce qui n'est pas toujours facile y compris pour l'handicapé qui n'acquiert aucune autonomie.So there is a need for continuous help available to the disabled, which is not always easy, even for the disabled who does not acquire any autonomy.

De même les fauteuils existants ont un repose-pieds qui ne participe pas à d'autres fonctions que celle de soutenir les pieds de l'handicapé lorsque celui-ci est en position de repos ou surtout lorsque le fauteuil est amené à être déplacé.Likewise, existing armchairs have a footrest which does not participate in any other function than that of supporting the feet of the handicapped person when the latter is in the rest position or especially when the armchair has to be moved.

De plus les fauteuils existants ont des mécanismes complexes et coûteux pour réaliser les différentes manoeuvres ce qui augmente les prix de revient et qui, parallèlement, en interdit l'accès aux plus démunis.In addition, the existing armchairs have complex and expensive mechanisms for carrying out the various maneuvers, which increases the cost prices and which, at the same time, prohibits access to them for the most disadvantaged.

La présente invention a pour objet un dispositif de positionnement notamment d'un handicapé entre une position allongée totale et une position quasi debout avec toutes les positions intermédiaires, dont le mécanisme de manoeuvre est simplifié de façon à le rendre encore plus fiable et à diminuer le prix de revient, dont l'utilisation reste simple avec possibilité de commande à la voix par exemple, dont les différents mouvements peuvent être programmés, qui peut être associé à d'autres appareils de transitique d'handicapés, qui présente toutes les garanties de sécurité quant au freinage pour l'immobilisation par rapport au sol lors du relevage vers la position quasi debout, qui est réglable en hauteur en fonction de la taille de la personne handicapée et notamment de sa hauteur de jambe, et dont l'assise elle-même peut être ajustée en fonction de la corpulence de la personne afin de permettre un passage dans la position quasi debout dans les meilleures conditions.The present invention relates to a device for positioning in particular a disabled person between a total lying position and an almost upright position with all the intermediate positions, the operating mechanism of which is simplified so as to make it even more reliable and to reduce the cost price, the use of which remains simple with the possibility of voice control for example, whose different movements can be programmed, which can be associated with other transitic devices for the disabled, which has all the safety guarantees as regards braking for immobilization with respect to the ground during lifting to the position almost upright, which is adjustable in height according to the size of the disabled person and in particular his leg height, and whose seat itself can be adjusted according to the body size of the person in order to allow a passage in the almost upright position in the best conditions.

A cet effet le dispositif de mise en position d'une personne, selon l'invention, notamment d'une personne handicapée, entre une position allongée et une position quasi debout avec toutes les positions intermédiaires, comprend un bâti pouvant être monté sur roues et se caractérise en ce qu'il comprend une assise horizontale mobile grâce à des premiers moyens moteurs entre deux positions extrêmes l'une de couchage et l'autre de relevage, un dossier mobile grâce à des seconds moyens moteurs entre deux positions extrêmes, l'une horizontale pour coopérer avec l'assise en formant un plan de couchage et l'autre inclinée en arrière par rapport à la verticale de façon à former un fauteuil avec l'assise.To this end, the device for positioning a person, according to the invention, in particular a disabled person, between a lying position and an almost upright position with all the intermediate positions, comprises a frame which can be mounted on wheels and is characterized in that it comprises a movable horizontal seat thanks to the first drive means between two extreme positions, one for lying down and the other for lifting, a movable backrest thanks to second drive means between two extreme positions, the one horizontal to cooperate with the seat by forming a sleeping plane and the other inclined backwards with respect to the vertical so as to form a chair with the seat.

Selon un mode de réalisation particulier de l'invention le dispositif comprend un bras monté par l'une de ses extrémités à rotation par rapport au bâti grâce à un axe transversal et muni à son extrémité libre d'un deuxième axe de rotation parallèle au premier, une plaque d'assise supportant l'assise proprement dite et solidaire de ce deuxième axe, des moyens de couplage étant interposés entre ces deux axes.According to a particular embodiment of the invention, the device comprises an arm mounted by one of its ends for rotation relative to the frame thanks to a transverse axis and provided at its free end with a second axis of rotation parallel to the first , a seat plate supporting the seat itself and integral with this second axis, coupling means being interposed between these two axes.

Selon un mode de réalisation particulier de l'invention les moyens de couplage comprennent un premier pignon fixe coaxial au premier axe et solidaire du bâti, un second pignon libre et coaxial au deuxième axe et une chaîne, montée parallèlement au bras, coopérant avec ces deux pignons.According to a particular embodiment of the invention, the coupling means comprise a first fixed pinion coaxial with the first axis and integral with the frame, a second free pinion and coaxial with the second axis and a chain, mounted parallel to the arm, cooperating with these two gables.

Selon une caractéristique particulière de l'invention le bras est réglable en longueur de façon à adapter la hauteur de relevage en position quasi debout à la morphologie de l'handicapé.According to a particular characteristic of the invention, the arm is adjustable in length so as to adapt the lifting height in the almost upright position to the morphology of the disabled.

L'assise comprend par ailleurs une partie avant munie de moyens d'escamotage progressif lorsque l'assise est en position relevée. Ces moyens d'escamotage peuvent avantageusement comprendre au moins un bras solidaire de la partie avant, monté pivotant par rapport à la plaque d'assise dans le plan vertical de façon que cette partie avant s'incline lorsque l'assise est relevée.The seat also comprises a front part provided with progressive retraction means when the seat is in the raised position. These retracting means can advantageously comprise at least one arm secured to the front part, pivotally mounted relative to the seat plate in the vertical plane so that this front part tilts when the seat is raised.

Selon un mode de réalisation préféré de l'invention, les premiers moyens moteurs comprennent une crosse solidaire du bras dont l'extrémité libre reçoit de façon articulée l'extrémité du piston d'un vérin dont le corps est articulé par rapport au bâti.According to a preferred embodiment of the invention, the first drive means comprise a stick secured to the arm, the free end of which receives in an articulated manner the end of the piston of a jack whose body is articulated relative to the frame.

De même le dossier est monté à rotation par rapport à un troisième axe parallèle aux premier et second axes, solidaire de l'arrière de la plaque d'assise.Similarly, the backrest is mounted for rotation relative to a third axis parallel to the first and second axes, secured to the rear of the seat plate.

Les seconds moyens moteurs appliqués au dossier comprennent au moins un premier pignon libre monté coaxialement par rapport au deuxième axe, au moins un second pignon solidaire du dossier et solidaire du troisième axe, une chaîne reliant ces premier et second pignons, des moyens de blocage du dossier en position relevée et au moins un levier pivotant, solidaire du premier pignon coopérant avec le bâti pour amener le dossier en position de couchage lorsque l'assise est elle-même en position basse.The second drive means applied to the backrest comprise at least a first free pinion mounted coaxially with respect to the second axis, at least a second pinion secured to the folder and secured to the third axis, a chain connecting these first and second gables, means for blocking the file in the raised position and at least one pivoting lever, integral with the first pinion cooperating with the frame to bring the file into the sleeping position when the seat is itself in the low position.

Le dispositif selon l'invention comprend de plus selon un perfectionnement un repose-pieds escamotable entre une position basse, dans laquelle il est dissimulé à l'intérieur du bâti et une position haute dans laquelle il est juxtaposé à l'assise lorsque celle-ci est en position basse de façon à former un plan de couchage complet.The device according to the invention further comprises, according to an improvement, a retractable footrest between a low position, in which it is concealed inside the frame and a high position in which it is juxtaposed with the seat when the latter is in the low position so as to form a complete sleeping surface.

The chain is arranged along the longitudinal axis parallel to the slide.

Le dispositif est complété par des moyens de freinage 86. Ces moyens de freinage sont représentés en détail sur la figure 4 et comprennent de chaque côte du bâti, à l'avant, un levier 88 pivotant par rapport au bâti et pressé vers le sol par des moyens de rappel, en l'occurence un ressort, de façon qu'un patin disposé à l'extrémité libre du levier assure le freinage par frottement. Il est également prévu des moyens de relevage de ces leviers lorsque le dispositif doit être déplacé. Ces moyens de relevage peuvent être réalisés par l'homme de l'art à l'aide de câbles reliés à la crosse notamment.The device is completed by braking means 86. These braking means are shown in detail in FIG. 4 and comprise on each side of the frame, at the front, a lever 88 pivoting relative to the frame and pressed towards the ground by return means, in this case a spring, so that a shoe disposed at the free end of the lever ensures braking by friction. Means are also provided for lifting these levers when the device has to be moved. These lifting means can be made by those skilled in the art using cables connected to the stock in particular.

Le fonctionnement du dispositif selon l'invention est décrit ci-après en faisant apparaître les avantages liés au dispositif et plus particulièrement au mode de réalisation préféré retenu.The operation of the device according to the invention is described below, showing the advantages linked to the device and more particularly to the preferred embodiment adopted.

Lorsque le dispositif assure la fonction lit, le dossier, l'assise y compris sa partie avant, et le repose-pieds sont dans un même plan. Dans ce cas, l'assise 12 est en position basse, le levier 70 coopère avec la came de guidage du bâti pour allonger le dossier, le vérin est en position d'extension et le parallélogramme est en saillie maximum si bien que le câble 81 est tendu tandis que les différents brins de la glissière sont en position d'extension.When the device performs the bed function, the backrest, the seat including its front part, and the footrest are in the same plane. In this case, the seat 12 is in the low position, the lever 70 cooperates with the guide cam of the frame to lengthen the backrest, the jack is in the extended position and the parallelogram is projecting as much as the cable 81 is stretched while the different strands of the slide are in the extended position.

Dès lors, l'handicapé peut agir sur les premiers moyens moteurs 42 pour passer de la position lit à la position fauteuil. Dans ce but, il commande le vérin électrique dont le piston par traction exerce un effort sur la crosse ce qui fait pivoter le bras 22 de l'assise autour du premier axe 26 transversal. Le levier 70 et son galet 72 quittent la came de guidage dont le profil assure le pivotement du dossier par rapport au troisième axe de rotation 60 jusqu'à ce que les moyens de verrouillage assurent le blocage en position du dossier par rapport à l'assise.Therefore, the disabled can act on the first motor means 42 to move from the bed position to the chair position. To this end, it controls the electric actuator, the piston of which exerts a force on the stick, which makes the arm 22 of the seat pivot around the first transverse axis 26. The lever 70 and its roller 72 leave the guide cam whose profile ensures the pivoting of the backrest relative to the third axis of rotation 60 until the locking means ensure the blocking in position of the backrest relative to the seat .

Simultanément, les moyens moteurs 78 entraînent la chaîne ce qui provoque la rentrée des glissières de façon télescopique, et a pour conséquence de replier le parallélogramme 74 et d'abaisser le repose-pieds proprement dit.Simultaneously, the motor means 78 drive the chain which causes the retraction of the slides telescopically, and has the consequence of folding the parallelogram 74 and lowering the footrest itself.

Durant la rotation du bras 22, la plaque d'assise 30 reste horizontale et s'écarte du cadre 20 du bâti 10. Durant ce déplacement, la partie avant 52 s'escamote par pivotement des bras 56 autour de l'axe transversal 58, l'extrémité frontale de cette partie avant 52 continuant à reposer sur le cadre 20. L'assise est donc dissociée de la partie avant ce qui réduit sa portée afin que seul le fessier de l'handicapé vienne en appui sur ladite assise. Si l'handicapé poursuit le mouvement il se retrouve dans une position quasi debout dans laquelle la hauteur de l'assise par rapport au sol est sensiblement égale à sa hauteur de jambes.During the rotation of the arm 22, the seat plate 30 remains horizontal and moves away from the frame 20 of the frame 10. During this movement, the front part 52 is retracted by pivoting the arms 56 around the transverse axis 58, the front end of this front part 52 continuing to rest on the frame 20. The seat is therefore dissociated from the front part which reduces its range so that only the buttocks of the disabled come to bear on said seat. If the handicapped person continues the movement, he finds himself in an almost upright position in which the height of the seat relative to the ground is substantially equal to his leg height.

Durant tout ce mouvement les moyens de freinage 86 ont assuré l'immobilisation du dispositif par rapport au sol.During all this movement the braking means 86 ensured the immobilization of the device relative to the ground.

La commande de ces différents mouvements s'effectue à l'aide de boutons de commande dans le cas où l'handicapé a l'usage de l'un de ses memebres supérieurs. Dans le cas contraire, il est également possible d'installer une commande à la voix ou par un pressostat commandé à la bouche.The control of these different movements is carried out using control buttons in the case where the disabled person has the use of one of his superior members. Otherwise, it is also possible to install a voice control or a mouth-operated pressure switch.

Selon une variante de l'invention, il est également possible de modifier les dimensions en largeur du dossier, de l'assise, du repose-pieds pour atteindre les dimensions standard d'un lit tout en gardant un châssis identique.According to a variant of the invention, it is also possible to modify the width dimensions of the backrest, the seat, the footrest to reach the standard dimensions of a bed while keeping an identical frame.

L'ensemble du dispositif est bien sûr habillé de façon à lui donner un aspect esthétique convenable et à assurer le confort de l'handicapé.The whole device is of course dressed so as to give it a suitable aesthetic appearance and to ensure the comfort of the disabled.

De même des accoudoirs solidaires de la plaque d'assise et relevables peuvent être associés au dispositif de façon simple.Likewise armrests integral with the seat plate and liftable can be associated with the device in a simple manner.

Ce dispositif est représenté dans le mode de réalisation principal avec des roues mais il est également possible d'adapter à l'arrière un train de roues de grand diamètre avec poignée circulaire pour assurer à l'handicapé un déplacement autonome à l'aide de ses membres supérieurs.This device is shown in the main embodiment with wheels, but it is also possible to adapt a large diameter wheel set with circular handle at the rear to ensure that the disabled person can move independently using his upper members.

De plus, le bras de longueur réglable permet de régler la tension de la chaîne en même temps qu'il permet de régler la position debout en fonction de la longueur des jambes de l'hanidcapé.In addition, the adjustable length arm allows you to adjust the chain tension at the same time as it allows you to adjust the standing position according to the length of the legs of the hanidcape.

De même, les diamètres des pignons et la longueur du levier permettent de modifier la vitese angulaire du dossier pendant la descente ainsi que l'effort de relevage tout en faisant varier l'angle d'inclinaison du dossier.Likewise, the diameters of the pinions and the length of the lever make it possible to modify the angular speed of the backrest during the descent as well as the lifting effort while varying the angle of inclination of the backrest.
