Abstract

The device has a body (1) fixed to a chassis receiving a piston (2), where piston slides inside the body. A spring (3) is received in the piston and the body, and is set in contact with a tampon (4) that locks a wheel of a wheel chair. A cable (5) is provided below a stretcher and connected to the piston, where the cable is arranged below a base of the wheel chair. The cable is stretched and is not stretched to unlock and lock the wheel, when the person is seated in the arm chair and person raises from the chair, respectively.

Description

La présente invention, concerne un dispositif de sécurité, pour bloquerThe present invention relates to a security device for blocking

automatiquement les roues d'un fauteuil roulant médical, lorsque la personne se lève. Lorsque la personne se lève, elle prend appuie sur le fauteuil, et si la personne ne pense pas à mettre les freins manuels, le fauteuil part en arrière et c'est la chute, entraînant souvent 5 de graves séquelles (col du fémur...) L'invention concerne un dispositif permettant de remédier à cela, sert à ce que le fauteuil ne recule pas, reste stable, et sécurise au mieux la personne. Les dessins annexés illustrent l'invention. Le premier dessin (page 1/4) représente l'ensemble du dispositif installé en vue arrière 10 Le dessin (page 2/4) est une vue de dessus. Lorsque la personne s'assoie sur le fauteuil, le câble (1) sous l'assise se tend et libère les tampons (2), et donc lorsque la personne se lève les tampons bloquent les roues. Le dessin (page 3/4) en coupe explique le mécanisme du dispositif bloquant les roues.  automatically the wheels of a medical wheelchair, when the person gets up. When the person gets up, she presses on the chair, and if the person does not think to put the manual brakes, the chair goes back and is the fall, often resulting in serious sequelae (neck of the femur .. The invention relates to a device for remedying this, is used so that the chair does not move back, remains stable, and best secures the person. The accompanying drawings illustrate the invention. The first drawing (page 1/4) represents the entire device installed in rear view. The drawing (page 2/4) is a view from above. When the person sits on the chair, the cable (1) under the seat is stretched and releases the pads (2), and so when the person gets up the pads block the wheels. The drawing (page 3/4) in section explains the mechanism of the device blocking the wheels.

15 Un corps (1) fixé au châssis du fauteuil reçoit le piston coulissant (2) qui par la pression du ressort (3) met le tampon (4) au contact de la roue et la bloque. Le schéma (2) explique le déblocage des freins, lorsque la personne s'assoie. Le câble (5) se tend, fait rentrer le piston coulissant (2) et le tampon (4) débloque la roue du fauteuil.A body (1) fixed to the frame of the chair receives the sliding piston (2) which by the pressure of the spring (3) puts the buffer (4) in contact with the wheel and blocks it. Diagram (2) explains the release of the brakes, when the person sits. The cable (5) stretches, retracts the sliding piston (2) and the buffer (4) releases the wheel of the chair.

20 Le dessein 4/4 explique le déblocage du système, pour le déplacement du fauteuil a vide. Deux manettes de frein (1) ; une manette placée à chaque poignée du fauteuil permet le déblocage des roues. La poignée (1) tend le câble (2) le piston coulissant rentre dans le corps (4) libérant les roues.The design 4/4 explains the unlocking of the system, for moving the vacuum chair. Two brake levers (1); a handle placed at each handle of the chair allows the unlocking of the wheels. The handle (1) tends the cable (2) the sliding piston enters the body (4) releasing the wheels.

25 Le dispositif à possibilité d'être installé sur tous les fauteuils et la sécurité qu'il offre permet d'éviter les chutes actuellement très nombreuses en maison de retraite notamment.The device with the possibility of being installed on all the armchairs and the safety that it offers makes it possible to avoid the falls currently very numerous in retirement home in particular.
