Description

La présente invention a pour objet un élévateur destiné à transporter des personnes entre un niveau inférieur et un niveau supérieur particulièrement destiné à être installé dans des habitations pour faciliter l'accès à l'étage des utilisateurs dont la mobilité est réduite telle que des personnes handicapées âgées par exemple.The present invention relates to an elevator for transporting people between a lower level and a higher level particularly intended to be installed in homes to facilitate access to the floor of users whose mobility is reduced such as people with disabilities elderly for example.

Dans ce domaine, on connaît bien des élévateurs comprenant une cabine ou une plate-forme horizontale apte à être translatée verticalement dans une cage verticale depuis un niveau inférieur jusqu'à un niveau supérieur et inversement par des moyens d'actionnement ; c'est le cas, par exemple, du brevet français FR 2.584.694 décrivant un ascenseur hydraulique avec une cabine. L'ascenseur hydraulique comporte une cabine qui est en liaison, par l'intermédiaire des moyens de support et de poulies de renvoi, avec un cylindre hydraulique déplaçable dans la direction de la course de la cabine, ladite cabine pouvant être montée et descendue par l'amenée et l'évacuation d'un liquide de travail. L'amenée du liquide de travail au cylindrique hydraulique s'effectue au moyen d'une pompe entraînée par un moteur. Ainsi, la tige dé piston du cylindre hydraulique ancrée de façon fixe avec son extrémité supérieure, qui peut sortir sous l'effet de l'apesanteur pour faire monter la cabine, est reliée à son extrémité à une poulie guidant le moyen de support ancré de façon fixe à l'une de ses extrémités et ancré sur la cabine à son autre extrémité.In this field, elevators are well known comprising a cabin or a horizontal platform able to be translated vertically in a vertical cage from a lower level to a higher level and vice versa by actuating means; this is the case, for example, of the French patent FR 2,584,694 describing a hydraulic lift with a cab. The hydraulic lift comprises a cabin which is connected, by means of the support means and return pulleys, with a hydraulic cylinder movable in the direction of travel of the cabin, said cabin being able to be raised and lowered by the supplying and discharging a working liquid. The working fluid is fed to the hydraulic cylinder by means of a pump driven by a motor. Thus, the piston rod of the hydraulic cylinder anchored in a fixed manner with its upper end, which can come out under the effect of weightlessness to raise the cabin, is connected at its end to a pulley guiding the anchored support means of fixed at one end and anchored to the cabin at the other end.

Bien que les moyens d'actionnement de ce type d'élévateur présente un volume limité, l'installation de ce type d'élévateur nécessite des travaux de gros oeuvre dans l'habitation qui grèvent considérablement le coût de pose de ce type d'élévateur.Although the actuating means of this type of elevator has a limited volume, the installation of this type of elevator requires structural work in the house that significantly increase the cost of laying this type of elevator .

Un autre élément est également connu de DE-A-4234490 , élévateur dit hydraulique dont la cabine est en liaison avec le piston d'un cylindre hydraulique afin de monter et descendre ladite cabine par l'amenée et respectivement l'évacuation d'un liquide de travail au cylindre hydraulique ; c'est le cas, par exemple, du brevet allemand DE 3.136.739 . Le cylindre hydraulique est en liaison, par l'intermédiaire d'une pompe, avec un accumulateur de pression conçu sous forme de cylindre, dont le piston est chargé par un contrepoids à travers la tige du piston.Another element is also known from DE-A-4234490 hydraulic elevator, whose cabin is connected to the piston of a hydraulic cylinder in order to raise and lower said cabin by the supply and respectively the evacuation of a working liquid to the hydraulic cylinder; it's the case, for example, of the German patent DE 3.136.739 . The hydraulic cylinder is connected, via a pump, with a pressure accumulator designed in the form of a cylinder, the piston of which is loaded by a counterweight through the piston rod.

On observera ainsi que la longueur du cylindre hydraulique correspond à la course maximale de la cabine de sorte que la hauteur d'élévation de la cabine est particulièrement limitée.It will thus be observed that the length of the hydraulic cylinder corresponds to the maximum stroke of the cabin so that the elevation height of the cabin is particularly limited.

Afin de remédier à cet inconvénient, on a déjà imaginé des dispositifs d'entraînement hydrostatiques permettant de grandes longueurs de course. C'est le cas, par exemple, du brevet européen EP 0.374.500 décrivant un système élévateur à ciseaux, utilisable notamment dans les garages pour lever des véhicules, comportant deux paires de bras montés en ciseaux, l'une des extrémités libres d'un bras d'une paire étant articulée autour d'un axe fixe solidaire du sol, l'autre extrémité étant articulée autour d'un axe coulissant le long de l'un des bords latéraux du châssis élévateur, l'autre bras ayant une extrémité articulée autour d'un axe fixe solidaire du bord latéral du châssis élévateur, et son autre extrémité articulée autour d'un axe coulissant le long du sol. Les deux bras d'une paire sont montés de manière pivotante selon un axe qui supporte une bielle, reliée de manière pivotante aux extrémités des deux vérins hydrauliques servant d'organe d'actionnement, selon un axe excentré de son axe de montage, pouvant tourner de 90° entre une position globalement horizontale et une position où elle sera bloquée en rotation. La bielle est avantageusement munie de roulettes afin que celles-ci permettent une montée rapide de l'axe de rotation qui lie les deux bras d'une paire entre eux, lorsque le châssis élévateur est en position base. De plus, l'existence de la bielle elle-même permet également, grâce à sa rotation, par démultiplication, une montée rapide de l'axe de rotation qui lie les deux bras d'une paire entre eux.In order to remedy this drawback, hydrostatic drive devices have already been devised which allow long stroke lengths. This is the case, for example, with the European patent EP 0.374.500 describing a scissor lift system, particularly usable in garages for lifting vehicles, comprising two pairs of scissor-mounted arms, one of the free ends of an arm of a pair being articulated around a fixed axis integral with the ground, the other end being hinged about an axis sliding along one of the lateral edges of the lifting frame, the other arm having an end articulated about a fixed axis integral with the lateral edge of the lifting frame, and its other end articulated around an axis sliding along the ground. The two arms of a pair are pivotally mounted on an axis which supports a connecting rod, pivotally connected to the ends of the two hydraulic cylinders acting as an actuating member, along an eccentric axis of its mounting axis, which can rotate 90 ° between a generally horizontal position and a position where it will be locked in rotation. The rod is advantageously provided with rollers so that they allow a rapid rise in the axis of rotation which binds the two arms of a pair between them, when the lift frame is in the base position. In addition, the existence of the rod itself also allows, thanks to its rotation, by reduction, a rapid rise in the axis of rotation which links the two arms of a pair between them.

Ce type d'élévateur présente l'inconvénient de nécessiter des travaux de gros oeuvre et de terrassement au fond de la cage pour réaliser une cuvette située sous le niveau inférieur pour accueillir le dispositif d'entraînement hydrostatique, ce qui grève considérablement les coûts de pose de tels élévateur. A défaut, la plate-forme de l'élévateur ne peut affleurer le niveau du sol lorsque l'élévateur est en position inférieure, les bras et l'organe d'actionnement étant disposés en dessous de la plate-forme.This type of elevator has the disadvantage of require structural work and earthworks at the bottom of the cage to make a bowl located below the lower level to accommodate the hydrostatic drive device, which significantly affect the costs of installation of such elevator. Otherwise, the platform of the elevator can not flush with the ground when the elevator is in the lower position, the arms and the actuating member being arranged below the platform.

L'un des buts de l'invention est donc de remédier à cet inconvénient en proposant un élévateur de conception simple et peu onéreuse évitant la réalisation d'une cuvette au fond de la cage de l'élévateur.One of the aims of the invention is therefore to overcome this disadvantage by proposing a lift of simple and inexpensive design avoiding the realization of a bowl at the bottom of the cage of the elevator.

A cet effet, et conformément à l'invention, il est proposé un élévateur entre un niveau inférieur et un niveau comprenant une cabine ou une plate-forme sensiblement horizontale apte à être translatée verticalement dans une cage verticale depuis le niveau inférieur jusqu'au niveau supérieur et inversement, par des moyens d'actionnement positionnés sous la plate-forme remarquable en ce que lesdits moyens d'actionnement comprennent d'une part au moins une paire de bras montés en ciseaux, c'est-à-dire articulés autour d'un axe dans leur partie médiane, les extrémités libres d'un premier bras d'une paire étant articulées autour d'un axe fixe solidaire de la cage et respectivement à la plate-forme autour d'un axe coulissant le long de l'un des bords latéraux de la plate-forme et les extrémités libres du second bras étant articulées autour d'un axe fixe solidaire du bord latéral de ladite plate-forme et respectivement à la cage autour d'un axe coulissant, de telle sorte que l'axe d'articulation du second bras à la plate-forme, l'axe médian d'articulation des bras d'une paire et l'axe d'articulation du premier bras à la cage ne soient jamais alignés, et d'autre part un organe d'actionnement coopérant avec au moins l'un des bras, l'actionnement dudit organe procurant la rotation du premier bras depuis une première position où ledit second bras s'étend au dessus de l'axe coulissant jusqu'à une seconde position inférieure où ledit premier bras s'étend en dessous dudit axe coulissant, assurant ainsi la translation de la plate-forme depuis une première position où elle s'étend au niveau supérieur de l'habitation jusqu'à une seconde position où elle s'étend au niveau inférieur sous ledit axe coulissant, et inversement.For this purpose, and according to the invention, there is provided an elevator between a lower level and a level comprising a cabin or a substantially horizontal platform able to be translated vertically in a vertical cage from the lower level to the level higher and vice versa, by actuating means positioned under the platform remarkable in that said actuating means comprise on the one hand at least one pair of scissor-mounted arms, that is to say articulated around an axis in their median part, the free ends of a first arm of a pair being hinged about a fixed axis integral with the cage and respectively at the platform about an axis sliding along the axis; one of the lateral edges of the platform and the free ends of the second arm being hinged about a fixed axis integral with the lateral edge of said platform and respectively to the cage about a sliding axis, such so that the axis of articulation of the second arm to the platform, the median axis of articulation of the arms of a pair and the axis of articulation of the first arm to the cage are never aligned, and d on the other hand an actuating member cooperating with at least one of the arms, the actuation of said member providing rotation of the first arm from a first position where said second arm extends above the sliding axis to a second lower position where said first arm extends below said sliding axis, thus ensuring the translation of the platform from a first position where it extends to the upper level of the dwelling to a second position where it s extends to the lower level under said sliding axis, and vice versa.

L'organe d'actionnement consiste, de préférence, en un vérin dont le corps est solidaire de la cage et dont la tige est articulée à une bielle articulée à l'un des bras de la paire de telle manière que les axes d'articulation de la bielle à la tige du vérin, de la bielle au premier bras et dudit premier bras à la cage ne soit jamais alignés.The actuating member consists, preferably, in a jack whose body is secured to the cage and whose rod is articulated to a rod articulated to one of the arms of the pair in such a way that the hinge pins from the connecting rod to the rod of the jack, from the rod to the first arm and from the first arm to the cage are never aligned.

Par ailleurs, et de manière particulièrement avantageuse, la cage est constituée d'une ossature comprenant deux montants arrières, deux longerons inférieurs et des traverses arrières, les extrémités libres du premier bras d'une paire étant articulées autour d'un axe fixe solidaire de l'extrémité arrière des longerons inférieurs et respectivement au plateau autour d'un axe coulissant le long de l'un des bords latéraux de la plate-forme et les extrémités libres du second bras étant articulées autour d'un axe fixe solidaire du bord latéral de la plate-forme et respectivement audit longeron inférieur autour d'un axe coulissant le long d'une lumière longitudinale pratiquée dans ledit longeron.Furthermore, and particularly advantageously, the cage consists of a frame comprising two rear uprights, two lower longitudinal members and rear cross members, the free ends of the first arm of a pair being hinged about a fixed axis integral with the rear end of the lower longitudinal members and respectively to the plate about an axis sliding along one of the lateral edges of the platform and the free ends of the second arm being articulated around a fixed axis integral with the lateral edge of the platform and respectively to said lower spar around an axis sliding along a longitudinal slot in said spar.

On comprend bien que, contrairement aux dispositifs de l'art antérieur, où la tige du dispositif d'entraînement hydrostatique est solidaire de la paroi inférieure de la cabine, en appui sur le sol sous le niveau inférieur, le vérin permettant d'entraîner la plate-forme depuis le2 niveau inférieur jusqu'au niveau supérieur et inversement s'étend au dessus dudit niveau inférieur de sorte que la pose d'un tel élévateur dans une habitation ne nécessite pas de travaux de terrassement pour la réalisation d'une cuvette.It is well understood that, unlike the devices of the prior art, where the stem of the hydrostatic drive device is integral with the lower wall of the cabin, resting on the ground below the lower level, the jack allowing to drive the platform from the lower level 2 to the upper level and conversely extends above said lower level so that the installation of such a lift in a dwelling does not require earthworks for the realization of a bowl .

De manière particulièrement avantageuse, l'un des bras de chaque paire de bras est constitué de deux segments, un premier segment et un second segment s'étendant linéairement et parallèlement dans deux plans verticaux distincts, lesdits segments étant reliés par un axe fixe solidaire des extrémités libres respectives des premier et second segments et traversant le premier bras de la paire.Particularly advantageously, one of the arms of each pair of arms consists of two segments, a first segment and a second segment. extending linearly and parallel in two distinct vertical planes, said segments being connected by a fixed axis integral with the respective free ends of the first and second segments and passing through the first arm of the pair.

En référence aux figures 1 à 3, l'élévateur suivant l'invention entre un niveau inférieur et un niveau supérieur d'une habitation comprend une plate-forme sensiblement horizontale 1 apte à être translatée verticalement dans une cage verticale 2 depuis le niveau inférieur 3 jusqu'au niveau supérieur 4 et inversement par des moyens d'actionnement positionnés sous ladite plate-forme 1. La cage 2 est constituée d'une ossature 5 comprenant deux montants avants 6a et deux montants arrières 6b, deux longerons inférieurs 7,7' et des traverses avants 8a et deux traverses arrières 8b. Les longerons inférieurs 7,7' de la cage 2 s'étendent au dessus du niveau inférieur 3 de l'habitation afin d'augmenter le débattement vertical de la plate-forme 1 comme il sera détaillé plus loin. La plate-forme horizontale 1 est constituée d'un plateau globalement rectangulaire 9 comprenant sur ses bords latéraux et sur son bord transversal arrière des rambardes 10 classiquement constituées de montants et de longerons formant des garde-corps.With reference to Figures 1 to 3 , the elevator according to the invention between a lower level and an upper level of a dwelling comprises a substantially horizontal platform 1 able to be translated vertically in a vertical cage 2 from the lower level 3 to the upper level 4 and inversely by actuating means positioned under said platform 1. The stand 2 comprises a frame 5 comprising two front uprights 6 and has two rear uprights 6b, two lower side members 7,7 'and 8 of the front cross members a and two rear rails 8 b . The lower longitudinal members 7,7 'of the cage 2 extend above the lower level 3 of the dwelling to increase the vertical movement of the platform 1 as will be detailed below. The horizontal platform 1 consists of a generally rectangular plate 9 comprising on its lateral edges and on its rear transverse edge railings 10 conventionally consist of uprights and rails forming railings.

L'élévateur comprend, par ailleurs, deux paires de bras 11 et 12 montés en ciseaux, c'est-à-dire une paire de bras articulés autour d'un axe dans leur partie médiane, respectivement articulés sur les bords latéraux de la plate-forme 1. Les extrémités libres du premier bras 11a d'une paire 11 sont articulés autour d'un axe fixe 13 solidaire de l'extrémité arrière du longeron inférieur 7 de l'ossature 5 de la cage 2 et respectivement à la plate-forme 1 autour d'un axe 14 coulissant le long de l'un des bords latéraux de ladite plate-forme 1 à travers une lumière longitudinale 15. Les extrémités libres du second bras 11b sont articulées autour d'un axe fixe 16 solidaire du bord latéral de la plate-forme 1 et respectivement dans la partie médiane du longeron inférieur 7 de l'ossature 5 de la cage 2 autour d'un axe 17 coulissant à travers une lumière longitudinale 18 pratiquée dans la partie médiane dudit longeron inférieur 7. On notera que, les paires de bras 11 et 12 étant articulées sur les bords latéraux de la plate-forme 1, l'espace situé sous cette dernière est entièrement libre, ce qui permet à ladite plate-forme 1 de s'étendre au niveau inférieur 3 sans que des travaux de terrassement soient nécessaires.The elevator comprises, moreover, two pairs of scissor-mounted arms 11 and 12, that is to say a pair of arms articulated about an axis in their central part, articulated respectively on the lateral edges of the plate. 1. The free ends of the first arm 11a of a pair 11 are hinged about a fixed axis 13 secured to the rear end of the lower spar 7 of the frame 5 of the cage 2 and respectively to the platform. form 1 about an axis 14 sliding along one of the lateral edges of said platform 1 through a longitudinal slot 15. The free ends of the second arm 11b are hinged about a fixed axis 16 integral with the side edge of the platform 1 and respectively in the median part of the lower spar 7 of the frame 5 of the cage 2 about an axis 17 sliding through a longitudinal slot 18 formed in the middle portion of said lower spar 7. It should be noted that, the pairs of arms 11 and 12 being articulated on the side edges of the platform 1, the space below the latter is completely free, which allows said platform 1 to extend to the lower level 3 without earthworks are necessary.

L'élévateur comprend, par ailleurs, un vérin 19 qui est alimenté par un moteur hydraulique, non représenté sur les figures, de manière à actionner ladite plate-forme 1. Ce vérin 19 s'étend verticalement le long du montant arrière 6a de l'ossature 5 de la cage 2, au-dessus du longeron inférieur 7, et la tige 20 dudit vérin 19 est articulée à une bielle 21 articulée au premier bras 11a de la paire entre l'articulation dudit premier bras 11a autour de l'axe fixe 13 solidaire de l'extrémité arrière du longeron inférieur 7 de l'ossature 5 de la cage 2 et l'axe d'articulation des premier et second bras 11a et 11b montés en ciseaux de sorte que les axes d'articulation de la bielle 21 à la tige 20 du vérin 19, de la bielle 21 au premier bras et dudit premier bras 11a à la cage 2 ne soient jamais alignés. Ainsi, la translation verticale de la tige 20 du vérin 19 entraîne la rotation du premier bras depuis une première position où ledit second bras s'étend au dessus des longerons inférieurs 7,7' de l'ossature 5 de la cage 2 jusqu'à une seconde position inférieure où ledit premier bras 11a s'étend en dessous desdits longerons inférieurs 7,7' procurant ainsi la translation de la plate-forme 1 depuis une première position où elle s'étend à l'étage supérieur 4 de l'habitation jusqu'à une seconde position où elle s'étend à l'étage inférieur 3 sous les longerons inférieurs 7,7' de l'ossature 5 de la cage 2.The elevator comprises, moreover, a jack 19 which is powered by a hydraulic motor, not shown in the figures, so as to actuate said platform 1. This jack 19 extends vertically along the rear upright 6 a of the frame 5 of the cage 2, above the lower beam 7 and the rod 20 of said cylinder 19 is articulated to a connecting rod 21 articulated to the first arm 11a of the pair between the hinge of said first arm 11a around the fixed shaft 13 secured to the rear end of the lower beam 7 of the frame 5 of the cage 2 and the axis of articulation of the first and second arms 11a and 11b connected in scissors so that the axes articulation of the connecting rod 21 to the rod 20 of the jack 19, the rod 21 of the first arm and said first arm 11a to the cage 2 are never aligned. Thus, the vertical translation of the rod 20 of the jack 19 causes the rotation of the first arm from a first position where said second arm extends above the lower longitudinal members 7,7 'of the frame 5 of the cage 2 to a second lower position where said first arm 11a extends below said lower side members 7,7 'and providing the translation of the platform 1 from a first position where it extends on the upper floor 4 of the housing to a second position where it extends to the lower floor 3 under the lower longitudinal members 7,7 'of the frame 5 of the cage 2.

Il va de soi que la position inférieure de la plate-forme 1 peut être confondue avec le plan des longerons 7,7' inférieurs de l'ossature 5 de la cage 2 sans pour autant sortir du cadre de l'invention. Néanmoins, on comprend bien que pour un même débattement vertical de la plate-forme 1, il conviendra de prévoir un vérin 19 dont le débattement de la tige 20 est plus important.It goes without saying that the lower position of the platform 1 may be confused with the plane of the longitudinal members 7,7 'of the frame 5 of the cage 2 without departing from the scope of the invention. Nevertheless, it is clear that for the same vertical movement of the platform 1, it will be necessary to provide a jack 19, the movement of the rod 20 is greater.

En référence à la figure 4, on observera que l'un des bras de chaque paire de bras 11,12 montés en ciseaux, le second bras 11b par exemple, est constitué de deux segments, un premier segment 11'b s'étendant depuis le longeron inférieur 7 jusqu'au premier bras 11b de la paire 11 et un second segment 11b s'étendant depuis le premier bras 11a de la paire 11 jusqu'à la plate-forme 1. Ces segments 11'b et 11"b s'étendent linéairement et parallèlement dans deux plans verticaux distincts et sont reliés par un axe fixe 22 solidaire des extrémités libres respectives des premier et second segments 11'b, 11"b et traversant le premier bras 11a de la paire 11. Ainsi, les premier et second segments 11'b et 11"b sont articulés autour d'un axe 2 traversent le premier bras 11a.With reference to the figure 4 it will be observed that one of the arms of each pair of scissor-mounted arms 11, 12, the second arm 11b, for example, consists of two segments, a first segment 11 ' b extending from the lower spar 7 to the first arm 11b of the pair 11 and a second segment 11b extending from the first arm 11a of the pair 11 to the platform 1. These segments 11'b and 11 "b extend linearly and in parallel in two separate vertical planes and are connected by a fixed shaft 22 secured to the respective free ends of first and second segments 11'b, 11 "b and passing through the first arm 11a of the pair 11. Thus, the first and second segments 11'b and 11 "b are hinged about an axis 2 through the first arm 11a.

Selon une variante d'exécution particulièrement avantageuse, représentée en traits pointillés sur la figure 4, les extrémités libres des bras 11b de la première paire 11 de bras sont solidarisées aux extrémités libres respectives des bras 12b de la seconde paire 12 de bras par une barre de liaison 23 de telle manière que la rotation du premier bras 11a de la première paire 11 procurée par l'actionnement du vérin 19 entraîne simultanément la rotation du premier bras 12a de la seconde paire 12. A cet égard, on notera que les bras 11a et 12a des paires 11 et 12 font saillie à l'arrière de la plate-forme 1 afin de permettre le passage de la barre de liaison 23 derrière la plate-forme lorsqu'elle est déplacée depuis le niveau inférieur 3 jusqu'au niveau supérieur 4 et inversement, ladite barre de liaison 23 s'étendant dans le plan de la plate-forme 1 lorsque cette dernière se situe au niveau des longerons inférieurs 7,7' de l'ossature 5.According to a particularly advantageous variant embodiment, represented in dotted lines on the figure 4 , the free ends of the arms 11b of the first pair 11 of arms are secured to the respective free ends of the arms 12b of the second pair of arms 12 by a connecting bar 23 so that the rotation of the first arm 11 has of the first pair 11 provided by actuating the actuator 19 simultaneously drives rotation of the first arm 12 a of the second pair 12. In this regard, it is noted that the arms 11a and 12a of pairs 11 and 12 protrude to the rear of the platform form 1 to allow the passage of the connecting bar 23 behind the platform when moved from the lower level 3 to the upper level 4 and vice versa, said connecting bar 23 extending in the plane of the platform 1 when the latter is located at the lower longitudinal members 7,7 'of the frame 5.

Accessoirement, en référence à la figure 1, l'élévateur comporte au niveau supérieur 4 un portillon 24 pivotant autour de charnières 25 solidaires des montants avants de l'ossature 5 de la cage 2 de telle manière que ledit portillon 24 soit fermé, empêchant l'accès à la cage 2, lorsque la plate-forme 1 se situe au niveau inférieur 3 afin d'empêcher toute chute depuis le niveau supérieur 4.Incidentally, with reference to figure 1 , the elevator comprises at the upper level 4 a gate 24 pivoting about hinges 25 secured to the front legs of the frame 5 of the cage 2 such that said gate 24 is closed, preventing access to the cage 2, when platform 1 is located at the lower level 3 to prevent any fall from the upper level 4.

On observera que le déplacement vertical de la plate-forme 1 dans la cage 2 n'est pas linéaire mais légèrement courbe de sorte que, lorsque ladite plate-forme 1 se situe au niveau inférieur 3 ou au niveau supérieur 4, ladite plate-forme 1 est séparée du plancher du niveau inférieur 3 ou supérieur par un espace. Afin d'empêcher qu'un utilisateur ne se coince le pied dans cet espace et ne se blesse, le bord avant de la plate-forme 1 comprend avantageusement une bavette 26 rétractable, précontrainte par des moyens élastiques et apte à coulisser le long de rails 27 positionnés sous ladite plate-forme 1 afin de combler ledit espace.It will be observed that the vertical displacement of the platform 1 in the cage 2 is not linear but slightly curved so that, when said platform 1 is at the lower level 3 or the upper level 4, said platform 1 is separated from the floor of the lower level 3 or higher by a space. In order to prevent a user from getting caught in this space and getting injured, the front edge of the platform 1 advantageously comprises a retractable flap 26, prestressed by elastic means and able to slide along rails. 27 positioned under said platform 1 to fill said space.

Il va de soi que le vérin 9 pourra être substitué par tout autre organe d'actionnement bien connu de l'homme de l'art sans sortir du cadre de l'invention, l'axe d'articulation de l'organe d'actionnement au bras 11a et l'axe d'articulation dudit bras 11a à la cage 2 ne devant alors jamais être aligné verticalement.It goes without saying that the cylinder 9 may be substituted by any other actuator well known to those skilled in the art without departing from the scope of the invention, the axis of articulation of the actuating member the arm 11a and the axis of articulation of said arm 11a to the cage 2 does never before then be aligned vertically.

Par ailleurs, il va de soi que les moyens d'actionnement de ladite plate-forme horizontale peuvent ne comprendre qu'une paire de bras montés en ciseaux, les extrémités libre d'un premier bras d'une paire étant articulé autour d'un axe fixe solidaire de la cage et respectivement au plateau autour d'un axe coulissant et les extrémités libre du second bras étant articulées autour d'un axe fixe solidaire de ladite plate-forme et respectivement à l'ossature de la cage autour d'un axe coulissant.Moreover, it goes without saying that the actuating means of said horizontal platform may not to understand that a pair of arms mounted scissors, the free ends of a first arm of a pair being articulated around a fixed axis integral with the cage and respectively to the plate about a sliding axis and the free ends of the second arm being articulated around a fixed axis integral with said platform and respectively to the frame of the cage around a sliding axis.

Enfin, il va de soi que la plate-forme horizontale de l'élévateur pourra être substituée par une cabine et que les exemples que l'on vient de donner ne sont que des illustrations particulières en aucun cas limitatives quant au domaine d'application de l'invention.Finally, it goes without saying that the horizontal platform of the elevator may be substituted by a cabin and that the examples that we have just given are only particular illustrations in no way limiting as to the scope of application of the invention.
