Abstract

Device intended to simplify the forward movement of an apparatus for handicapped persons, patented under No. 88/000,51 and granted on 27.10.89. This assembly consists of two free wheels, two notched levers, two rods with special orifices, and two rollers. When a handicapped person bears on the notched lever or levers, these set the free wheels in rotation, by way of the rods, which free wheels mesh and advance the apparatus one step. The rods which comprise orifices of special shapes make it possible to adjust the length of the steps in a virtually instantaneous manner, and they are used for traction and as a counterweight.

Description

Ce certificat d'addition se rattachant au brevet
N 8800051, délivré le e7/10/89 est destiné à simplifier le système de traction et de rappel des leviers C2 de 1'apparei' et à remplacer les poulies à cliquet à deux gorges C15) par deux roues dentées genre roue libre, à supprimer les deux contrepoids C2O, leurs deux tubes anti bal ancement C19) et les poulies d'élévation C185. Les câbles de traction C3) sont remplacés par des tringles à orifices de formes spéciales.This certificate of addition relating to the patent
N 8800051, issued on e7 / 10/89 is intended to simplify the traction and return system of the C2 levers of the device and to replace the ratchet pulleys with two grooves C15) by two toothed freewheels, remove the two counterweights C2O, their two anti-anchoring tubes C19) and the elevation pulleys C185. The traction cables C3) are replaced by rods with orifices of special shapes.

C e t t e nouvelle disposition diminue d'une façon importante les dimensions du mécanisme C5D, aussi bien en surface qu'en hauteur, ainsi que son poids. This new arrangement considerably reduces the dimensions of the C5D mechanism, both in terms of surface and height, as well as its weight.

Ce dispositif est composé de de deux roues libres, lesquelles lorsqu'elles sont enclenchées entrainent la roue dentée C11) et provoquent
l'avancée d'un pas de l'appareil.This device is composed of two free wheels, which when engaged cause the gear C11) and cause
one step forward of the device.

b) de deux leviers à crans. b) two notched levers.

de de deux tringles qui reliant les leviers aux roues libres servent à la fois à la traction et de contrepoids de rappel. of two rods which connect the levers to the freewheels are used both for traction and as a return counterweight.

d) de deux galets. d) two rollers.

FONCTIONNEMENT :
Lorsque l'on appuie sur le ou les leviers, les tringles, dans les orifices desquels les dents des roues libres pénètrent, entraînent en rotation les roues libres, lesquelles font tourner la roue dentée C11) et provoquent l'avancée d'un pas de l'appareil.OPERATION:
When the lever (s) are pressed, the rods, into the orifices of which the teeth of the freewheels penetrate, rotate the freewheels, which rotate the toothed wheel C11) and cause a step of the device.

Les orifices des tringles d'après leurs formes permettent un léger débattement vers l'avant et vers l'arrière, de changer de cran sur les leviers, et de pouvoir ainsi régler la longueur des pas. The holes of the rods according to their shapes allow a slight deflection forwards and backwards, to change notch on the levers, and thus to be able to adjust the length of the steps.

Les leviers se relèvent d'eux même, ramenés par le poids des tringles faisant office de contrepoids. The levers are raised by themselves, brought down by the weight of the rods acting as a counterweight.

Les deux galets servent à maintenir les tringles appliquées contre les roues libres.  The two rollers are used to hold the rods applied against the freewheels.
