Description

La présente invention concerne un pont pour fauteuil orthopédique électrique, notamment pour faciliter l'accès à des véhicules, tel que décrit dans la première partie de la revendication 1.The present invention relates to a bridge for an electric orthopedic chair, in particular for facilitating access to vehicles, as described in the first part of claim 1.

Elle concerne également une rampe pour fauteuil orthopédique pour permettre la montée ou la descente d'escaliers telle que décrite dans la première partie de la revendication 10.It also relates to a ramp for an orthopedic chair to allow the ascent or descent of stairs as described in the first part of claim 10.

Un pont du type ci-dessus est connu du brevet US-A 4,528,711. Il présente cependant l'inconvénient d'être assez encombrant dans sa position repliée et de ne pas pouvoir être manoeuvré aisément par le conducteur du fauteuil.A bridge of the above type is known from US-A 4,528,711. However, it has the disadvantage of being quite bulky in its folded position and of not being able to be easily operated by the driver of the wheelchair.

Le brevet US-A 4,539,781 décrit, quant à lui, une rampe qui permet de faire gravir des escaliers à un fauteuil orthopédique.Patent US-A 4,539,781 describes, for its part, a ramp which makes it possible to climb stairs to an orthopedic chair.

Les ponts existants pour le chargement des fauteuils orthopédiques sont, soit rigides, coulissant dessous, soit rétractables à l'arrière pour les remorques de véhicules ou pour les gros véhicules. Quant à ceux destinés aux automobiles, ils comportent un système à vérin particulièrement onéreux, en raison de l'utilisation de la force motrice, électrique ou à compression, du véhicule transporteur.The existing bridges for loading orthopedic chairs are either rigid, sliding underneath, or retractable at the rear for vehicle trailers or for large vehicles. As for those intended for automobiles, they comprise a particularly expensive jack system, due to the use of the motive force, electric or compression, of the carrier vehicle.

La présente invention a pour but de remédier à ces inconvénients. L'invention telle qu'elle est caractérisée dans les revendications résout les problèmes liés à l'utilisation de véhicules particuliers équipés de vérins ou rampes non démontables, en proposant un dispositif fait de pièces légères toutes repliables et escamotables, susceptibles d'être contenues dans une caisse avec poignée transformable en remorque tractable par le fauteuil électrique.The object of the present invention is to remedy to these disadvantages. The invention as characterized in the claims solves the problems associated with the use of private vehicles fitted with non-removable jacks or ramps, by proposing a device made of light parts, all of which are foldable and retractable, which may be contained in a body with handle transformable into a trailer towable by the electric wheelchair.

Ces problèmes sont résolus par l'objet des revendications 1 et 10, les revendications dépendantes concernant des modes avantageux de réalisation de l'invention.These problems are solved by the subject of claims 1 and 10, the dependent claims relating to advantageous embodiments of the invention.

Les avantages inhérents à la présente invention résident essentiellement en ce qu'elle permet de charger un fauteuil roulant orthopédique, dans des conditions de sécurité satisfaisantes, dans des véhicules de type break, en utilisant l'énergie de traction propre du fauteuil, ainsi que de le déplacer sur des escaliers, sans auxiliaires d'accompagnement.The advantages inherent in the present invention lie essentially in that it makes it possible to load an orthopedic wheelchair, under satisfactory safety conditions, in station wagon vehicles, using the chair's own traction energy, as well as move it on stairs, without accompanying aids.

L'invention est exposée ci-après en détail à l'appui du dessin annexé, dans lequel :

  • la figure 1 représente une vue en perspective d'un rail du pont selon l'invention ;
  • la figure 2 représente une vue en coupe transversale du même pont au niveau d'une entretoise ;
  • la figure 3 représente une vue latérale d'une rampe d'escalier selon l'invention ;
  • la figure 4 représente une vue en coupe transversale du dispositif de serrage d'un élément de la rampe d'escalier.
The invention is set out below in detail in support of the appended drawing, in which:
  • FIG. 1 represents a perspective view of a rail of the bridge according to the invention;
  • Figure 2 shows a cross-sectional view of the same bridge at a spacer;
  • Figure 3 shows a side view of a stair rail according to the invention;
  • Figure 4 shows a cross-sectional view of the clamping device of an element of the stair railing.

Le pont de chargement représenté dans les figures 1 et 2 a pour avantage d'être léger, indéformable aux intempéries et facile à manier.The loading bridge shown in Figures 1 and 2 has the advantage of being light, non-deformable in bad weather and easy to handle.

Si on se réfère à la figure 1, on voit que chaque rail se compose de quatre éléments de sections en U de largeur décroissante, emboîtables en position de repli. Le premier élément 38, le plus large, de ces rails comporte à son extrémité des crochets 39 arrondis à 90°, destinés à servir de points d'arrimage au véhicule. L'élément suivant 40 s'emboîte dans l'élément 38, l'assemblage étant maintenu par une patte de maintien 41 fixée à la face inférieure de l'élément 40.If we refer to Figure 1, we see that each rail consists of four elements of U-shaped sections of decreasing width, nestable in the folded position. The first element 38, the widest, of these rails comprises at its end hooks 39 rounded at 90 °, intended to serve as points lashing to the vehicle. The next element 40 fits into the element 38, the assembly being maintained by a retaining tab 41 fixed to the underside of the element 40.

Le rail 40 est muni à sa face inférieure et en son centre d'un perçage 42 pour le passage d'un téton 43 solidaire d'une entretoise 44 qui réunit les rails 40 disposés parallèlement, aux trois quarts de leur longueur. Les rails suivants 45 et 46 sont imbriqués selon le même processus que les deux précédents. Pour des raisons de risque de fléchissement, d'état de déclivité de la route ou du véhicule, les rails 38 - 40 - 45 - 46 doivent être déployés par pièces de 2, 3 ou 4 éléments ne dépassant jamais 2 mètres.The rail 40 is provided at its lower face and in its center with a bore 42 for the passage of a stud 43 secured to a spacer 44 which joins the rails 40 arranged in parallel, three-quarters of their length. The following rails 45 and 46 are nested according to the same process as the previous two. For reasons of risk of deflection, of declivity of the road or of the vehicle, the rails 38 - 40 - 45 - 46 must be deployed in pieces of 2, 3 or 4 elements never exceeding 2 meters.

Si on se réfère à la figure 2, on voit que l'entretoise 44 est constituée d'une cornière en U renversé 47 dans laquelle sont vissés des tétons 43 destinés à recevoir les rails 40 à des intervalles calculés en fonction des dimensions d'écartement des roues du fauteuil orthopédique.Referring to Figure 2, we see that the spacer 44 consists of an inverted U angle 47 in which are screwed studs 43 for receiving the rails 40 at intervals calculated according to the spacing dimensions wheels of the orthopedic chair.

Cette cornière 47 est destinée à recevoir en son centre, articulés par des goupilles 48, des pieds télescopiques 49 formés de tubes 50 et 51 emboîtables bloqués par des vis papillons 52. Les rails 40, de même que les rails 38, 45 et 46 sont percés à chaque embout et en leurs extrémités pour recevoir en position de montage des rivets plats à collerettes 53 dans lesquels s'enclavent des clips 54, de manière à assurer la rigidité de l'ensemble.This angle iron 47 is intended to receive at its center, articulated by pins 48, telescopic legs 49 formed of interlocking tubes 50 and 51 locked by butterfly screws 52. The rails 40, as well as the rails 38, 45 and 46 are drilled at each end piece and at their ends to receive in the mounting position flat rivets with flanges 53 in which clips 54 are enclosed, so as to ensure the rigidity of the assembly.

Si on se réfère à la figure 3, on voit que la rampe selon l'invention se compose de plaques 59 de longueur réglable et d'équerres 57 de section en forme de L dont les faces internes sont aptes à venir en appui sur la face supérieure et la contre-marche des marches d'un escalier. Sur chaque équerre sont montés deux supports de plaque 55 destinés à recevoir chacun une plaque 59. Chaque support 55 est constitué par deux profilés en U 56 reliés entre eux par une entretoise 561 de sorte que l'ouverture des U constitue deux rainures parallèles distantes de la largeur des plaques 59. Ces profilés en U 56 comportent des vis de fixation 562 des plaques 59, et ils sont assemblés deux à deux au moyen d'un axe 563 solidaire du sommet de l'équerre 57 et permettant le pivotement de l'un par rapport à l'autre, l'axe 563 se confondant avec le sommet de l'équerre 57.If we refer to Figure 3, we see that the ramp according to the invention consists of plates 59 of adjustable length and brackets 57 of L-shaped section whose internal faces are adapted to bear on the face upper and the step of the steps of a staircase. On each bracket are mounted two plate supports 55 intended to each receive a plate 59. Each support 55 is constituted by two U-shaped profiles 56 connected to each other by a spacer 561 so that the opening of the U constitutes two parallel grooves distant from the width of the plates 59. These sections in U 56 comprise fixing screws 562 of the plates 59, and they are assembled two by two by means of an axis 563 secured to the top of the bracket 57 and allowing the pivoting of one relative to the other, the axis 563 merging with the top of the bracket 57.

Une toise 571 est montée en rotation sur un des bras de l'équerre 57, par exemple à l'aide d'une goupille. Cette toise 571 est destinée à venir se bloquer en appui sur la plaque 59, par exemple dans une encoche ménagée à cet effet dans ladite plaque. Les plaques 59 peuvent être munies à leur face inférieure de coussinets de mousse 591 destinés à venir en appui sur l'arête des marches de l'escalier. La plaque d'amorce peut être équipée d'un crampon en caoutchouc 592 connu en soi. De préférence, la longueur des plaques 59 est réglable entre 46 cm et 70 cm pour recouvrir, avec les supports de plaque 55, 2 à 3 marches de hauteur moyenne.A height rod 571 is mounted in rotation on one of the arms of the bracket 57, for example using a pin. This height rod 571 is intended to come to bear in abutment on the plate 59, for example in a notch provided for this purpose in said plate. The plates 59 may be provided at their lower face with foam pads 591 intended to come to bear on the edge of the steps of the staircase. The primer plate can be fitted with a rubber stud 592 known per se. Preferably, the length of the plates 59 is adjustable between 46 cm and 70 cm to cover, with the plate supports 55, 2 to 3 steps of average height.

Si on se réfère à la figure 4, on voit que le dispositif de serrage et d'assemblage des éléments de la rampe d'escalier comporte les profilés en U 56 en position latérale, soudés entre eux sur l'entretoise 561 sur laquelle coulissent les plaques 59, les profilés en U 56 étant munis de leurs vis de fixation 562.Referring to FIG. 4, it can be seen that the device for clamping and assembling the elements of the stair railing comprises the U-shaped profiles 56 in the lateral position, welded together on the spacer 561 on which the plates 59, the U-shaped profiles 56 being provided with their fixing screws 562.
