i Dispositif de maintien à niveau des nacelles des fauteuils roulantsi Leveling device for wheelchair gondolas
DESCRIPTIONDESCRIPTION
la présente invention à pour objet le maintien à niveau et assiette constante des nacelles des fauteuils roulants, ainsi qu'au maintien à la même hauteur, par rapport au niveau du sol ou de la marche de l'escalier mécanique sur lequel se trouve la personne the object of the present invention is to maintain the level and constant attitude of the nacelles of wheelchairs, as well as to maintain it at the same height, relative to the ground level or the step of the escalator on which the person is located.
animant la propulsion, de la poignée de guidage et de propulsion du dit fauteuil. animating the propulsion, the guide handle and propulsion of said chair.
Le secteur technique de l'invention est celui des appareils, appareillages et procédés Mis en oeuvre pour le transport des adultes et des enfants au moyen de fauteuils The technical sector of the invention is that of apparatus, apparatus and processes used for the transport of adults and children by means of armchairs.
Roulants et autres appareils de transport. Rolling stock and other transport devices.
Le transport des adultes et enfants au moyen de fauteuils roulants, présente des inconvénients bien connus lorsqu'il s'agit de propulser l'ensemble à un niveau 15 supérieur ou inférieur en utilisant un escalier mécanique -Lorsque le fauteuil se trouve positionné sur l'escalator, dans le sens de la montée, les roues avant se trouvent à deux marches au dessus des roues arrières, et le passager est allongé dans la nacelle qui est déséquilibrée, sa tête étant plus basse que le niveau de ses pieds... De plus la poignée de guidage et de propulsion du fauteuil se trouve de ce fait 20 beaucoup plus basse que son niveau habituel et oblige la personne qui anime l'opération, à se livrer à des contorsions dangereuses pour ramener l'ensemble fauteuil nacelle à une position horizontale, telle qu'on obtient lorsque les roues avant et arrière du fauteuil sont en position horizontales.il en va de même, mais en sens inverse lorsque le fauteuil se trouve positionné sur l'escalier mécanique dans le sens de la descente. La présente invention vise à apporter une solution radicale et à éliminer le danger Provoqué par cette situation.A cet effet, le dispositif (figl) est constitué d'un châssis (1) équipé de roues(8) et d'un ensemble tubulaire(2) sur lequel est fixée une armature (3) qui supporte la nacelle du fauteuil. L'ensemble pivote autour d'un axe essieu The transport of adults and children by means of wheelchairs has well-known drawbacks when it comes to propelling the assembly to a higher or lower level using an escalator -When the wheelchair is positioned on the escalator, in the upward direction, the front wheels are two steps above the rear wheels, and the passenger is lying in the basket which is unbalanced, his head being lower than the level of his feet ... De the more the guide and propulsion handle of the chair is therefore much lower than its usual level and obliges the person leading the operation to engage in dangerous contortions in order to bring the platform chair assembly back to a position horizontal, as obtained when the front and rear wheels of the chair are in the horizontal position; the same is true, but in the opposite direction when the chair is positioned on the stairs mechanical in the direction of descent. The present invention aims to provide a radical solution and to eliminate the danger caused by this situation. To this end, the device (figl) consists of a chassis (1) fitted with wheels (8) and a tubular assembly ( 2) on which is fixed a frame (3) which supports the chair nacelle. The assembly pivots around an axle axis
(7) et les amplitudes des mouvements sont amorties et freinées par un frein 30 amortisseur(6). (7) and the amplitudes of the movements are damped and braked by a damping brake (6).
A l'extérieur du tube(2) coulisse un autre tube(5) qui constitue la poignée de Guidage et de propulsion du fauteuil. Ce tube(5) qui coulisse à l'extérieur du tube (2) vient buter sur un piston(l0) (fig2) coulissant lui aussi à l'intérieur du tube(5) (fig2) lequel piston(l 0) est fixé au moyen d'un filetage(l 2) sur le tube(2).La bielle 35 (4) est reliée, à une extrémité, au tube(5) par une platine(5 bis) au moyen d'un axe pivotant(5 ter) et à son autre extrémité, au châssis(l) par une platine(l3) et axe On the outside of the tube (2) slides another tube (5) which constitutes the Guidance and propulsion handle of the chair. This tube (5) which slides outside the tube (2) abuts on a piston (l0) (fig2) also sliding inside the tube (5) (fig2) which piston (l 0) is fixed by means of a thread (l 2) on the tube (2). The connecting rod 35 (4) is connected, at one end, to the tube (5) by a plate (5 bis) by means of a pivoting axis ( 5b) and at its other end, to the frame (l) by a plate (l3) and axis
pivotant(9) (fig2).swivel (9) (fig2).
Lorsque les roues arrières sont en position haute par rapport aux roues avant(fig3) la Bielle(4) pousse le tube(5) qui se trouve de ce fait propulsé vers l'extérieur(haut) du Tube(2). A l'inverse, lorsque les roues arrières du fauteuil sont en position basse par rapport aux roue avant(fig4), la bielle(4) tire sur le tube(5) qui coulisse sur le tube(2) qui de ce When the rear wheels are in the high position relative to the front wheels (fig3) the connecting rod (4) pushes the tube (5) which is therefore propelled towards the outside (top) of the tube (2). Conversely, when the rear wheels of the chair are in the low position relative to the front wheel (fig4), the connecting rod (4) pulls on the tube (5) which slides on the tube (2) which therefore
fait se trouve propulsé vers l'intérieur(bas) du tube(2). fact is propelled towards the inside (bottom) of the tube (2).
Ce dispositif permet, d'une part: De maintenir l'armature(3) (figl) sur laquelle est fixée la nacelle du fauteuil, et ce Quelque soient les positions des roues avant ou arrière, aussi bien à la montée qu'à 10 la descente de l'escalier mécanique, et d'autre part: maintenir l'extrémité du tube(5) qui est en fait la poignée de guidage et de propulsion du fauteuil, toujours à la même distance du sol ou de la marche de l'escalier mécanique sur laquelle se trouve la This device allows, on the one hand: To maintain the frame (3) (figl) on which is fixed the nacelle of the wheelchair, and this Whatever the positions of the front or rear wheels, both when climbing or at 10 the descent of the escalator, and on the other hand: maintain the end of the tube (5) which is in fact the guide and propulsion handle of the chair, always at the same distance from the ground or from the step escalator on which the
personne qui guide et propulse le fauteuil. person who guides and propels the chair.
Le blocage et le déblocage de l'ensemble constitué par le tube(2) et le tube(5) se fait 15 au moyen d'un levier(1l5) (fig5 et 6) prolongé d'un doigt(19) (fig6) lequel pénètre The blocking and unblocking of the assembly constituted by the tube (2) and the tube (5) is done by means of a lever (1l5) (fig5 and 6) extended by a finger (19) (fig6) which enters
dans le tube(5) solidaire du tube(2). in the tube (5) integral with the tube (2).
La désolidarisation du tube(5) du tube(2) s'obtient par la pression exercée par The separation of the tube (5) from the tube (2) is obtained by the pressure exerted by
L'accompagnateur, sur le levier(15) au niveau du ressort(16). The guide, on the lever (15) at the spring (16).
La resolidarisation entre le tube(5) et le tube(2) s'effectue automatiquement par la 20 poussée exercée par le ressort(16) sur le levier(15), lorsque les trous(20) et(21) se The connection between the tube (5) and the tube (2) takes place automatically by the thrust exerted by the spring (16) on the lever (15), when the holes (20) and (21) are
