Description

Plate-forme~élévatrice
La pressente invention concerne une plate-forme élévatrice qui peut être fixée à une structure fixe ou a un véhicule
Lorsqu'il est fixé a une structure, le dispositif peut servir à soulever des marchandises pour lés amener à un niveau plus élevé et les déplacer ensuite dans une direction horizontalee
Avec un véhicule, le nouveau dispositif pourrait servir à charger des marchandises sur un véhicule et à les en décharger et également à monter un fauteuil roulant avec son occupant sur un véhicule ou à l'en descendre.
Platform ~ lifting
The present invention relates to a lifting platform which can be fixed to a fixed structure or to a vehicle.
When attached to a structure, the device can be used to lift goods to bring them to a higher level and then move them in a horizontal direction
With a vehicle, the new device could be used to load and unload goods onto a vehicle and also to mount or dismount a wheelchair with its occupant on a vehicle.

Un avantage spécial du nouveau dispositif réside dans le fait que dans le cas où il est fixé à un véhicule, la plate forme fait partie de la caisse du véhicule et ntaugmente donc pas sensiblement le poids mort du véhicule, c'est-à-dire ne diminue pas sa capacité de transport qui est d'une importance spéciale dans le cas de véhicules motorisés de petite taille destinés au transport des invalides et de leurs fauteuils roulants. A special advantage of the new device lies in the fact that in the case where it is fixed to a vehicle, the platform forms part of the body of the vehicle and therefore does not appreciably increase the dead weight of the vehicle, i.e. does not reduce its transport capacity which is of special importance in the case of small motorized vehicles intended for the transport of invalids and their wheelchairs.

La pressente invention a pour objet un dispositif du type mentionné qui se distingue par une structure simple et par son prix de revient relativement faible. The object of the present invention is a device of the type mentioned which is distinguished by a simple structure and by its relatively low cost price.

Ce dispositif nouveau selon la présente invention comprend un élément formant plaque partir d'un des bords duquel s'détend un bras court sensiblement perpendiculaire au plan de l'élément formant plaque, deux bielles télescopiques étant articulées audit bras, une de ces bielles tant un vérin et les extrémités opposes desdites bielles étant articulées à un élément fixe, des moyens de commande classiques étant prévus pour raire fonctionner le vérin0
On comprendra que le terme '3fixe" désigne un état immobile par rapport aux déplacements de la plate-forme elévatrice et du vérin, le cas où le dispositif est fixé à un véhicule (qui n'est pas toujours "immobile") étant donc inclus dans ce terme.
This new device according to the present invention comprises a plate element from one edge of which extends a short arm substantially perpendicular to the plane of the plate element, two telescopic connecting rods being articulated to said arm, one of these connecting rods being a cylinder and the opposite ends of said connecting rods being articulated to a fixed element, conventional control means being provided to make the cylinder operate.
It will be understood that the term '3fixe' designates a stationary state with respect to the displacements of the lifting platform and of the jack, the case where the device is fixed to a vehicle (which is not always "stationary") being therefore included. in this term.

On va maintenant décrire la présente invention en se retirant aux dessins annexés, sur lesquels
les ligures 1, 2, 3, 4 sont des vues en élévation schématiques du nouveau dispositif a differents stades de lonctionnement ; et
la figure 5 est une vue en plan qui montre deux utilisations possibles du nouveau dispositif,
Le nouveau dispositif, dans son ensemble, est supporté par un elément fixe 1 qui peut être un montant, comme représenté sur les tigures 1-4, et qui peut être de n'importe quel type ou avoir n'importe quelle lorme et être, par exemple, le mur d'un immeubles
Au montant 1 sont articulées, aux points 2 et 3 qui se trouvent dans la partie supérieure extrême de l'élément 1, deux bielles telescopiques 4 et 50
La bielle 4 consiste en une partie extérieure 4a et en une partie intérieure extensible 4b. La bielle 5 est un vérin pneumatique ou hydraulique et consiste en une partie formant cylindre Sa et en une partie formant piston 5b qui comprend la tige de piston extensible. L'extrémité inférieure extrême de la partie 4b est coudée en 6 et est articulée en 7 à un bras court 8 qui s'étend depuis l'élément formant plaque 9 perpendiculairement au plan de cet élément 9.
We will now describe the present invention by withdrawing from the accompanying drawings, in which
Figures 1, 2, 3, 4 are schematic elevational views of the new device at different stages of operation; and
FIG. 5 is a plan view which shows two possible uses of the new device,
The new device, as a whole, is supported by a fixed element 1 which can be an upright, as shown in figures 1-4, and which can be of any type or have any shape and be, for example, the wall of a building
At the upright 1 are articulated, at points 2 and 3 which are located in the extreme upper part of the element 1, two telescopic connecting rods 4 and 50
The connecting rod 4 consists of an outer part 4a and an extensible inner part 4b. The connecting rod 5 is a pneumatic or hydraulic cylinder and consists of a part forming a cylinder Sa and a part forming a piston 5b which comprises the extendable piston rod. The extreme lower end of the part 4b is bent at 6 and is articulated at 7 to a short arm 8 which extends from the plate element 9 perpendicular to the plane of this element 9.

La tige de piston. de la partie 5b est articulée en 10 au bras 8o Le dispositif comporte les commandes cl-assiques pour le vérin 5, c'est-à-dire une petite pompe actionnée soit par un moteur électrique (ou le moteur du véhicule, si le dispo- sitif est supporté par un véhicule) 9 et l'agencement de valve dirigeant le fluide sous pression sur l'un ou l'autre côté du piston du vérin 50
Le fonctionnement de ce nouveau dispositif apparaît clairement dans les figures 1-4. Â partir de la position entierement rappelée représentée sur la figure t, on actionne le dispositif en dirigeant le fluide sous pression de manière a provoquer l'extension du vérin Sa Par suite du déplacement vers le bas du piston et du déplacement vers l'extérieur de la tige 5b, la bielle 4 est amenée pivoter vers l'extérieur, -comme on peut le voir sur la figure 2, et si le déplacement vers l'extérieur de la tige 5b de piston continue, la partie inferieure 4b de la bielle 4 se déplace également jusqu'à ce que cette bielle se trouve dans sa position d'extension0
Lorsque la tige 4b a atteint sa position d'extension extrême (fig. 3), mais que le déplacement vers l'extérieur de la partie formant piston 5b du vérin 5 continue, le bras court 8 pivote dans la direction de la flèche X jusqugà ce qu'il atteigne la position représentée sur la figure 4 il en résulte que la plaque 9, laquelle est fixée rigidement au bras 8 perpendiculairement à ce dernier, prend une position horizontale et forme une plate formensur laquelle on peut placer une charge,ou bien se comporte comme une rampe sur laquelle un invalide peut venir (ou être amené) dans son fauteuil roulant.
The piston rod. of part 5b is articulated in 10 to the arm 8o The device comprises the cl-assic controls for the jack 5, that is to say a small pump actuated either by an electric motor (or the vehicle engine, if available) - sitive is supported by a vehicle) 9 and the valve arrangement directing the fluid under pressure on either side of the piston of the jack 50
The operation of this new device is clearly shown in Figures 1-4. From the fully recalled position shown in Figure t, the device is actuated by directing the fluid under pressure so as to cause the extension of the cylinder Sa Following the downward movement of the piston and the outward movement of the rod 5b, the connecting rod 4 is brought to pivot outwards, as can be seen in FIG. 2, and if the displacement towards the outside of the piston rod 5b continues, the lower part 4b of the connecting rod 4 also moves until this connecting rod is in its extended position0
When the rod 4b has reached its position of extreme extension (fig. 3), but the displacement towards the outside of the piston-forming part 5b of the jack 5 continues, the short arm 8 pivots in the direction of the arrow X up to what it reaches the position shown in FIG. 4 it follows that the plate 9, which is rigidly fixed to the arm 8 perpendicularly to the latter, takes a horizontal position and forms a flat platform on which a load can be placed, or else behaves like a ramp on which an invalid can come (or be brought) in his wheelchair.

En actionnant convenablement le vérin, on peut inverser le déplacement décrit jusqu'à ce que la position reprësentée en traits interrompus sur la figure 4 soit atteinte, c'estFàwdire la position où la plate-forme 9 se trouve à son niveau le plues haut, les marchandises pouvant être déplacées de celle-ci ou bien le fauteuil roulant pouvant etre déplacé vers l'intérieur du véhicule concernés
La figure 5 montre l'utilisation du nouveau dispositif dans deux exemples différents.On a représenté un véhicule A à moteur dont la carrosserie, selon la moitié supérieure de la figure 5 (au-dessus de la ligne en traits mixtes) peut être celle d'un camion, tandis que selon la moitié inférieure du dessin, elle peut être celle d'une fourgonnetteo La paroi latérale 20 du camion est supportée par deux des nouveaux dispositifs indiqués d'une façon générale par la référence 210 Les deux dispositifs 21 sont actionnés simultanément de la manière décrite et, lorsque l'on abaisse la paroi latérale 20, celle-ci forme une plate-forme large sur laquelle on peut placer des marchandises pour les soulever jusqu'au niveau de la plateforme du camion de manière qu'on puisse facilement les pousser sur celle-ci.
By properly actuating the jack, the displacement described can be reversed until the position shown in broken lines in FIG. 4 is reached, that is to say the position where the platform 9 is at its highest level, goods which can be moved therefrom or the wheelchair which can be moved inside the vehicle concerned
Figure 5 shows the use of the new device in two different examples. A motor vehicle A is shown, the bodywork of which, along the upper half of Figure 5 (above the dashed line) can be that of 'a truck, while according to the lower half of the drawing, it can be that of a van The side wall 20 of the truck is supported by two of the new devices indicated generally by the reference 210 The two devices 21 are actuated simultaneously as described and, when the side wall 20 is lowered, this forms a wide platform on which goods can be placed to lift them up to the level of the platform of the truck so that could easily push them on it.

Selon la moitie-inférieure de la figure 5, la porte carrière d'une fourgonnette est divise (horizontalement; en deux parties, seule la partieinférieure etant représentée. Cette porte arrière est supportée par un seul dispositif 22 et, lorsqu'elle est abaissée, la porte 23 forme une rampe prête à recevoir un fauteuil roulant et son occupant. Dans ce cas, un seul dispositif 22 surfit pour supporter la rampe 230
Bien que l'exemple de la figure 5 montre l'utilisation d'un nouveau dispositif sur un véhicule, il va de soi que ce dispositif pourrait être utilisé de nombreuses façons diffé- rentes, par exemple avec des stores, dans des magasins, etc,, où il serait supporté par un mur de l'immeuble.
According to the lower half of FIG. 5, the quarry door of a van is divided (horizontally; into two parts, only the lower part being shown. This rear door is supported by a single device 22 and, when lowered, the door 23 forms a ramp ready to receive a wheelchair and its occupant. In this case, a single device 22 surfaces to support the ramp 230
Although the example in Figure 5 shows the use of a new device on a vehicle, it goes without saying that this device could be used in many different ways, for example with blinds, in shops, etc. ,, where it would be supported by a wall of the building.
