Description

La présente invention concerne tous les types de rames ferroviaires comportant au moins un véhicule ferroviaire muni de :

  • une caisse munie d'au moins un plancher fixe délimitant un couloir de circulation s'étendant suivant la longueur du véhicule,
  • une plateforme s'étendant entre deux faces latérales de la caisse, déposée en regard d'une ouverture de la caisse normalement fermée par un vantail, et mobile verticalement par rapport au plancher, entre une position haute dans laquelle la plateforme est alignée avec le plancher et une position basse dans laquelle la plateforme est désalignée avec le plancher, la position basse correspondant à une situation d'embarquement / de débarquement, et
  • au moins un passage mobile entre le plancher et la plateforme mobile.
The present invention relates to all types of railway trains comprising at least one railway vehicle provided with:
  • a box provided with at least one fixed floor defining a corridor of traffic extending along the length of the vehicle,
  • a platform extending between two lateral sides of the box, deposited opposite an opening of the box normally closed by a leaf, and movable vertically with respect to the floor, between a high position in which the platform is aligned with the floor and a low position in which the platform is misaligned with the floor, the low position corresponding to a loading / unloading situation, and
  • at least one movable passage between the floor and the mobile platform.

Les véhicules ferroviaires ont avantageusement un dispositif d'accès comprenant une plateforme d'accès mobile verticalement et un passage mobile entre la plateforme et un plancher fixe du véhicule. La plateforme est mobile verticalement par rapport au plancher afin d'une part, de s'ajuster à la hauteur du quai pour les phases d'embarquement et de débarquement et d'autre part, en phase de circulation du véhicule, de placer à la même hauteur la plateforme et les planchers. Ainsi, un tel dispositif permet aux personnes à mobilité réduite d'accéder au véhicule depuis des quais de différentes hauteurs de façon autonome, mais aussi de pouvoir circuler dans l'ensemble du véhicule ferroviaire.Railway vehicles advantageously have an access device comprising a vertically movable access platform and a movable passage between the platform and a fixed floor of the vehicle. The platform is movable vertically with respect to the floor in order to adjust to the height of the platform for the loading and unloading phases and, in the vehicle circulation phase, to place the same height the platform and the floors. Thus, such a device allows people with reduced mobility to access the vehicle from docks of different heights independently, but also to be able to circulate throughout the railway vehicle.

Le document FR2918339 ou EP 2011 714 décrit un véhicule ferroviaire comportant une telle plateforme mobile verticalement par rapport à la caisse, associée à une rampe mobile assurant la jonction entre la plateforme d'accès et le plancher fixe de l'espace voyageurs. L'inclinaison de la rampe varie avec les déplacements verticaux de la plateforme d'accès. Dans certains cas, l'ajustement de la hauteur de la plateforme à la hauteur du quai peut induire un grand déplacement vertical de la plateforme, se répercutant par une forte inclinaison de la rampe. Cependant, les spécifications techniques d'interopérabilité préconisent une pente maximale de 12%. Afin de respecter ces spécifications, la longueur de la rampe doit être assez importante et peut nécessiter la suppression de sièges dans les extrémités de l'espace voyageurs.The document FR2918339 or EP 2011 714 describes a railway vehicle comprising such a platform movable vertically relative to the body, associated with a movable ramp connecting the access platform and the fixed floor of the passenger compartment. The inclination of the ramp varies with the vertical movements of the access platform. In some cases, adjusting the height of the platform to the height of the platform can induce a large vertical displacement of the platform, reflected by a steep slope of the ramp. However, the technical specifications for interoperability recommend a maximum slope of 12%. In order to meet these specifications, the length of the ramp must be quite large and may require the removal of seats in the ends of the passenger compartment.

US 5,316,432 décrit un dispositif formant à la fois un escalier et un ascenseur mais ne permettant pas la liaison entre d'une plateforme mobile et d'un plancher, notamment lorsqu'ils sont au même niveau. US5,316,432 describes a device forming both a staircase and an elevator but not allowing the connection between a mobile platform and a floor, especially when they are at the same level.

In the circulation phase of the railway vehicle 1, the platform 18 is aligned with the floors 15 and 16 as shown in FIG. figure 1 .

Le dispositif comprend également des passages mobiles 21 et 22 visibles en détail sur les figures 2 et 3. Le passage mobile 21 réalise la jonction entre le plancher 15 et la plateforme mobile 18 et le passage mobile 22 réalise la jonction entre le plancher 16 et la plateforme mobile 18. Ainsi, ces passages mobiles forment un chemin plan ou ascendant/descendant dont la ligne de plus grande pente s'étend suivant la longueur du véhicule.The device also comprises movable passages 21 and 22 visible in detail on the Figures 2 and 3 . The movable passageway 21 makes the junction between the floor 15 and the mobile platform 18 and the movable passageway 22 connects the floor 16 to the mobile platform 18. Thus, these movable passages form a planar or ascending / descending path whose line greater slope extends along the length of the vehicle.

Les passages 21 et 22 sont symétriques l'un de l'autre par rapport à un plan transversal du véhicule. Dans un autre exemple de réalisation, les passages 21 et 22 sont décalés.The passages 21 and 22 are symmetrical to one another with respect to a transverse plane of the vehicle. In another embodiment, the passages 21 and 22 are shifted.

Le passage mobile 21 (respectivement 22) entre la plateforme mobile 18 et le plancher fixe 15 (respectivement 16) comprend deux marches mobiles 24 et 25 (respectivement 27 et 28), ou plus de deux marches.The movable passage 21 (respectively 22) between the mobile platform 18 and the fixed floor 15 (respectively 16) comprises two movable steps 24 and 25 (respectively 27 and 28), or more than two steps.

Des mains courantes 30 adaptées aux personnes à mobilité réduite sont fixées sur des parois du véhicule de part et d'autre des passages mobiles 21 et 22.Handrails 30 adapted to persons with reduced mobility are fixed on vehicle walls on either side of the mobile passages 21 and 22.

Dans la suite, seul le passage 21 sera décrit en détails, le passage 22 étant structurellement et cinématiquement identique au passage 21.In the following, only the passage 21 will be described in detail, the passage 22 being structurally and kinematically identical to the passage 21.

Le dispositif d'accès comprend un système d'entraînement 29, visible sur la figure 4, comportant deux paires de poutres 31 et 31'. Chaque paire de poutres 31 et 31' est articulée en ciseaux et placée au-dessous de la plateforme 18, entre la caisse 3 du véhicule et la plateforme 18. Un actionneur, non représenté, est relié entre les poutres d'une même paire pour assurer leur rapprochement ou leur écartement. Cet actionneur est par exemple pneumatique, hydraulique, ou électrique. En cas de panne ou manque d'énergie, l'actionneur est manoeuvrable manuellement en mode dégradé.The access device comprises a drive system 29, visible on the figure 4 , having two pairs of beams 31 and 31 '. Each pair of beams 31 and 31 'is articulated in scissors and placed below the platform 18, between the body 3 of the vehicle and the platform 18. An actuator, not shown, is connected between the beams of the same pair for ensure their approximation or their separation. This actuator is for example pneumatic, hydraulic, or electric. In case of failure or lack of energy, the actuator is manually operable in degraded mode.

Les marches mobiles 24 et 25 sont portées par des moyens d'entraînement 32. Ces moyens d'entraînement 32 sont ici un portique d'entraînement comprenant deux bielles parallèles 33A et 33B. Les deux bielles 33A et 33B sont placées chacune de part et d'autre du passage 21, de sorte que l'ensemble formé possède une symétrie par rapport à un plan médian transversal.The moving steps 24 and 25 are carried by drive means 32. These drive means 32 are here a drive gantry comprising two parallel links 33A and 33B. The two rods 33A and 33B are each placed on either side of the passage 21, so that the assembly formed has a symmetry with respect to a transverse median plane.

Comme illustré sur la figure 4, dans les notations des références annotées sur les dessins annexés, la lettre A indique le côté latéral du passage 21 considéré, sachant que le même chiffre suivi de la lettre B indique le même organe, mais symétrique sur l'autre côté latéral du passage 21.As illustrated on the figure 4 in the notations of references annotated in the accompanying drawings, the letter A indicates the lateral side of the passage 21 considered, knowing that the same number followed by the letter B indicates the same organ, but symmetrical on the other lateral side of the passage 21 .

Chaque bielle 33A et 33B comprend une première extrémité articulée par rapport à la plateforme 18 au moyen d'une articulation 35A, 35B, et une seconde extrémité articulée par rapport au plancher 15 au moyen d'une articulation 34A, 34B. En référence à la figure 4, l'articulation 35 est fixée en partie supérieure du système d'entraînement 29. La partie supérieure du système d'entraînement 29 est solidaire de la plateforme 18.Each connecting rod 33A and 33B comprises a first end hinged to the platform 18 by means of a hinge 35A, 35B, and a second end hinged to the floor 15 by means of a hinge 34A, 34B. With reference to the figure 4 , the articulation 35 is fixed in the upper part of the drive system 29. The upper part of the drive system 29 is integral with the platform 18.

Dans la suite, seul un côté latéral du passage 21 sera décrit en détails.In the following, only one lateral side of the passage 21 will be described in detail.

La bielle 33A est montée coulissante par rapport au plancher 15 dans une direction longitudinale grâce à une coulisse 36A prévue à son extrémité articulée. La coulisse 36A comprend une lumière oblongue 38A formée dans une potence 41A solidaire de la partie basse 4 de la caisse 3. L'articulation 34A est montée coulissante dans la lumière oblongue 38A. A son extrémité articulée sur la plateforme 18 par l'articulation 35A, la bielle 33A est fixe en translation.The rod 33A is slidably mounted relative to the floor 15 in a longitudinal direction by a slide 36A provided at its articulated end. The slide 36A comprises an oblong slot 38A formed in a bracket 41A secured to the lower part 4 of the box 3. The hinge 34A is slidably mounted in the oblong slot 38A. At its articulated end on the platform 18 by the articulation 35A, the connecting rod 33A is fixed in translation.

En variante, non représentée, la potence 41A est fixée à la partie basse 4, par l'intermédiaire d'une pièce d'attache.Alternatively, not shown, the bracket 41A is fixed to the lower part 4, via a fastener.

Dans une variante, la coulisse 36A est située sur la tranche latérale de la plateforme 18. La bielle 33A a alors son extrémité articulée fixe en translation sur le plancher 15.In a variant, the slide 36A is located on the lateral edge of the platform 18. The rod 33A then has its articulated end fixed in translation on the floor 15.

Chaque marche 24 et 25 comporte latéralement et de chaque côté, un flanc 43A, 44A. Chaque flanc est solidaire de la marche correspondante et réalise un angle droit avec la surface supérieure de la marche correspondante. La bielle 33A s'étend sous chaque marche 24 et 25 contre les surfaces au regard des flancs 43A et 44A. Elle est articulée sur chaque flanc 43A, 44A par des articulations notées respectivement 46A et 47A. Ces articulations 46A et 47A sont montées coulissantes par exemple dans des lumières oblongues 48A et 49A, visibles en figure 4, et s'étendant longitudinalement.Each step 24 and 25 comprises laterally and on each side, a flank 43A, 44A. Each side is integral with the corresponding step and makes a right angle with the upper surface of the corresponding step. The connecting rod 33A extends under each step 24 and 25 against the surfaces facing the flanks 43A and 44A. It is articulated on each flank 43A, 44A by joints respectively noted 46A and 47A. These articulations 46A and 47A are slidably mounted, for example in oblong slots 48A and 49A, visible in figure 4 , and extending longitudinally.

Chaque marche 24 et 25 est également pourvue d'une contremarche 24C, 25C transversale, et d'une tranche 24D, 25D transversale. Dans le sens courant de montée d'une marche, la contremarche désigne la paroi visible à l'avant de la marche et la tranche la paroi à l'arrière. De même, le plancher 15 comprend une contremarche 15C. Respectivement, un système de notations analogue est utilisé pour les marches 27 et 28 et le plancher 16. La plateforme 18 comprend une première tranche 18D transversale et adjacente à la marche 25, et une deuxième tranche 18D' transversale et adjacente à la marche 28.Each step 24 and 25 is also provided with a transverse riser 24C, 25C transverse, and a slice 24D, 25D transverse. In the usual direction of climbing a step, the riser designates the visible wall at the front of the step and slice the wall at the back. Similarly, the floor 15 comprises a riser 15C. Respectively, a similar notation system is used for the steps 27 and 28 and the floor 16. The platform 18 comprises a first transverse portion 18D and adjacent to the step 25, and a second portion 18D 'transverse and adjacent to the step 28.

Après activation du système d'entraînement 29, d'une part, la plate-forme 18 est déplacée entre une première position P1, correspondant à une position haute de la plate-forme 18 visible sur la figure 5, et une seconde position P2, correspondant à une position basse de la plateforme 18 visible sur la figure 6, et d'autre part, les marches 24 et 25 sont déplacées par l'intermédiaire du portique d'entraînement 32 sous l'effet de son entraînement par la plateforme 18.After activation of the drive system 29, on the one hand, the platform 18 is moved between a first position P1, corresponding to a high position of the platform 18 visible on the figure 5 , and a second position P2, corresponding to a low position of the platform 18 visible on the figure 6 and, on the other hand, the steps 24 and 25 are moved through the drive gantry 32 as a result of being driven by the platform 18.

En référence à la figure 4, lorsque la plate-forme 18 est dans la position haute P1, la plate-forme 18 est alignée avec le plancher 15, 16. Le train est alors soit en circulation, soit à l'arrêt.With reference to the figure 4 when the platform 18 is in the high position P1, the platform 18 is aligned with the floor 15, 16. The train is then either in circulation or at a standstill.

Lorsque la plateforme 18 est dans la position basse P2, la plateforme 18 est désalignée avec le plancher 15, 16. Dans ce cas, la marche 24, respectivement 25, est dans une position intermédiaire Pi1, respectivement Pi2, les positions intermédiaires Pi1, Pi2, étant comprises entre la position haute P1 et la position basse P2. Le train est alors dans une situation d'embarquement / de débarquement.When the platform 18 is in the low position P2, the platform 18 is misaligned with the floor 15, 16. In this case, the step 24, respectively 25, is in an intermediate position Pi1, respectively Pi2, the intermediate positions Pi1, Pi2 , being between the high position P1 and the low position P2. The train is then in a situation of embarkation / disembarkation.

De plus, les marches 24, 25 sont guidées en translation verticale lors de leurs déplacements. En référence à la figure 6, le guidage en translation verticale est assuré par l'appui des surfaces de contact transversales, entre la contremarche 24C de la marche 24 et la tranche 25D de la marche 25, entre les tranches 24D de la marche 24 et la tranche 15C du plancher 15, et entre la contremarche 25C de la marche 25 et la tranche 18D de la plateforme 18. Ces surfaces de contact sont propres à coopérer pour assurer le guidage en translation verticale des marches 24 et 25. Un raisonnement analogue s'appliquant pour les marches 27 et 28, les contremarches 27C, 28C et 16C, les tranches 27D, 28D et 18D' et le plancher 16, la description correspondante ne sera donc pas détaillée par la suite.In addition, the steps 24, 25 are guided in vertical translation during their movements. With reference to the figure 6 , the vertical translation guidance is provided by the support of the transverse contact surfaces, between the riser 24C of the step 24 and the edge 25D of the step 25, between the slices 24D of the step 24 and the slice 15C of the floor 15 and between the riser 25C of the step 25 and the edge 18D of the platform 18. These contact surfaces are adapted to cooperate to provide vertical translation guidance of the steps 24 and 25. Similar reasoning applying to the steps 27 and 28, the risers 27C, 28C and 16C, the slices 27D, 28D and 18D 'and the floor 16, the corresponding description will therefore not be detailed later.

En variante, chaque flanc 43A et 44A comporte sur sa surface extérieure deux pions notés 51A et 52A pour le flanc 43A et notés 53A et 54A pour le flanc 44A, reçus dans des rails, non visibles, ménagés verticalement dans la caisse 3 du véhicule pour assurer un guidage en translation vertical par rapport à la caisse 3.In a variant, each flank 43A and 44A has on its outer surface two pegs 51A and 52A for the flank 43A and noted 53A and 54A for the sidewall 44A, received in rails, which are not visible, arranged vertically in the body 3 of the vehicle for ensure vertical translational guidance with respect to the body 3.

Comme visible sur les figures 2 et 3, le dispositif d'accès comprend en outre un tiroir 63 coulissant par rapport à la plateforme dans le plan de celle-ci et disposé entre le vantail 10 et la plateforme 18 dans l'espace d'accès 6 pour combler l'espace entre le vantail 10 et la plateforme 18. La caisse 3 comprend deux glissières sensiblement verticales 66 et 67 dont le profil épouse la forme du vantail 10. Les glissières 66 et 67 sont écartées l'une de l'autre d'une distance égale à la largeur du tiroir obturateur 63. Le tiroir 63 comporte de part et d'autre de son bord faisant face au vantail 10 des galets reçus à coulissement dans les glissières 66 et 67. Le tiroir obturateur 63 est monté coulissant horizontalement et parallèlement à la plateforme 18 dans la direction normale au vantail 10 grâce à des coulisses 69 et 70 portés par la plateforme 18.As visible on Figures 2 and 3 , the access device further comprises a slide 63 sliding relative to the platform in the plane thereof and disposed between the leaf 10 and the platform 18 in the access space 6 to fill the space between the leaf 10 and the platform 18. The box 3 comprises two substantially vertical slides 66 and 67 whose profile matches the shape of the leaf 10. The slides 66 and 67 are spaced apart from each other by a distance equal to the width 63. The drawer 63 comprises on either side of its edge facing the leaf 10 of the rollers slidably received in the slideways 66 and 67. The shutter slide 63 is slidably mounted. horizontally and parallel to the platform 18 in the normal direction to the leaf 10 through slides 69 and 70 carried by the platform 18.

Le dispositif d'accès comprend une palette comble-lacune 77 motorisée par rapport à la caisse 3 du véhicule entre une position rétractée dans la caisse, illustrée sur la figure 2, et une position sortie hors de la caisse illustrée sur la figure 3.The access device comprises a fill-gap gap 77 motorized relative to the body 3 of the vehicle between a retracted position in the body, illustrated on the figure 2 , and a position taken out of the box shown on the figure 3 .

Dans sa position rétractée, la palette 77 est entièrement escamotée dans la caisse 3 du véhicule au-dessous de la plateforme 18. En position sortie, la palette 77 fait saillie hors de la caisse 3 en travers d'une lumière ménagée dans la caisse sous le vantail 10. Un deuxième système d'entraînement, non représenté, de type hydraulique, pneumatique ou électrique permet le déplacement de la palette comble-lacune 77 entre ces deux positions.In its retracted position, the pallet 77 is completely retracted into the body 3 of the vehicle below the platform 18. In the extended position, the pallet 77 protrudes out of the box 3 across a light formed in the box under the leaf 10. A second drive system, not shown, of the hydraulic, pneumatic or electric type allows the displacement of the gap-gap pallet 77 between these two positions.

La caisse 3 comprend sous la plateforme 18 des rails 78 et 79 disposés perpendiculairement à l'ouverture 9 et écartés d'une distance égale à la largeur de la palette 77. La palette 77 est montée coulissante sur les rails 78 et 79, elle est également montée pivotante autour d'un axe longitudinal situé sous le seuil de l'ouverture 9 lorsqu'elle est dans sa position sortie, c'est-à-dire en fin de course de son déplacement en translation le long des rails 78 et 79.The box 3 comprises under the platform 18 rails 78 and 79 arranged perpendicular to the opening 9 and spaced apart by a distance equal to the width of the pallet 77. The pallet 77 is slidably mounted on the rails 78 and 79, it is also pivotally mounted about a longitudinal axis located below the threshold of the opening 9 when in its extended position, that is to say at the end of its travel in translation along the rails 78 and 79 .

Le véhicule comprend également un système de commande non représenté. Ce système comprend tout ou partie des moyens suivants :

  • un moyen de détection de la hauteur d'un quai 80 par rapport à la caisse 3, qui comprend par exemple un capteur de distance ou une caméra,
  • un moyen de détection de masse située au niveau de chaque passage mobile 21 et 22, qui est par exemple un capteur de force capacitif ou piézoélectrique,
  • un moyen de détection d'obstacle situé à l'extrémité de la palette comble-lacune 77, et
  • un calculateur pour calculer à partir de la hauteur du quai 80 détectée, une position optimale de la plateforme 18, c'est-à-dire celle qui garantit une pente inférieure à 12% de la palette mobile comble-lacune 77 lorsqu'elle est sortie et pivotée, et
  • des moyens d'asservissement de la plate-forme 18 pour son déplacement jusqu'à la position optimale calculée, correspondant à la position d'embarquement / de débarquement.
The vehicle also comprises a control system not shown. This system includes all or some of the following means:
  • means for detecting the height of a platform 80 with respect to the body 3, which comprises, for example, a distance sensor or a camera,
  • mass detection means located at each movable passage 21 and 22, which is for example a capacitive or piezoelectric force sensor,
  • obstacle detection means located at the end of the gap-gap pallet 77, and
  • a calculator for calculating from the height of the platform 80 detected, an optimal position of the platform 18, that is to say the one which guarantees a slope less than 12% of the gap-gap pallet 77 when it is output and rotated, and
  • servo means of the platform 18 for its movement to the calculated optimum position, corresponding to the embarkation / disembarkation position.

Donnée également uniquement à titre d'exemple, une utilisation possible de l'invention est détaillée dans la partie suivante.Also given by way of example only, a possible use of the invention is detailed in the following section.

Dans un premier temps, en se référant aux figures 1 et 2, le véhicule ferroviaire est en phase de circulation. La plateforme 18 est en position haute de sorte qu'il n'y a pas de dénivelé entre la plateforme 18 et chacun des planchers 15 et 16. Des personnes à mobilité réduite peuvent alors se déplacer de façon autonome dans l'ensemble du véhicule ferroviaire.At first, by referring to figures 1 and 2 , the railway vehicle is in circulation phase. The platform 18 is in a high position so that there is no difference in level between the platform 18 and each of the floors 15 and 16. From reduced mobility can then move autonomously throughout the rail vehicle.

Dans un deuxième temps, en se référant aux figures 7 à 11, le véhicule ferroviaire arrive au quai 80 et un procédé d'ajustement de l'accès démarre.In a second step, referring to Figures 7 to 11 , the railway vehicle arrives at platform 80 and an access adjustment process starts.

Les personnes à mobilités réduites se placent sur la plateforme 18. La présence d'une personne ou d'un objet sur un des passages mobiles 21 et 22 provoque la mise en attente du procédé d'ajustement du fait du capteur de force placé sous le passage 21. Le capteur de position mesure la hauteur du quai 80 par rapport à la caisse 3. L'information est ensuite traitée par le calculateur. A partir de cette information, le calculateur calcule la position optimale de la plateforme 18. Enfin, la plateforme 18 est déplacée en translation verticale par rapport au quai 80, vers la position calculée, via le système d'entraînement 29 en ciseaux placé sous la plateforme 18. Le mouvement de la plateforme 18 entraîne, par l'intermédiaire du portique 32 d'entraînement articulé, les passages 21 et 22 à se déformer pour former ainsi des escaliers, simultanément, le tiroir obturateur 63 est entraîné en translation verticale le long des glissières 66 et 67. Le tiroir 63 coulisse alors parallèlement à la plateforme 18 afin d'épouser le profil galbé du vantail 10 et garantir une obturation totale entre la plateforme 18 et le vantail 10.The persons with reduced mobility are placed on the platform 18. The presence of a person or an object on one of the movable passages 21 and 22 causes the setting process to be put on hold due to the force sensor placed under the 21. The position sensor measures the height of the platform 80 relative to the body 3. The information is then processed by the computer. From this information, the computer calculates the optimal position of the platform 18. Finally, the platform 18 is moved in vertical translation relative to the platform 80, to the calculated position, via the scissor drive system 29 placed under the platform 18. The movement of the platform 18 drives, through the hinged gantry 32, the passages 21 and 22 to be deformed to thereby form stairs, simultaneously, the shutter slide 63 is driven in vertical translation along slides 63 and 67. The slide 63 then slides parallel to the platform 18 in order to match the curved profile of the leaf 10 and ensure complete closure between the platform 18 and the leaf 10.

La palette comble-lacune 77 coulisse également le long des coulisses 78 et 79 pour sortir en saillie de la caisse 3 sous le vantail 10.The gap-gap pallet 77 also slides along the slides 78 and 79 to protrude out of the box 3 under the leaf 10.

Dans un premier cas, illustré par les figures 7 et 8, où la hauteur du quai 80 est égale ou légèrement supérieure à celle de la palette 77, la palette 77 vient en butée contre le quai avant la fin de sa course (figures 7-8).In the first case, illustrated by Figures 7 and 8 , where the height of the platform 80 is equal to or slightly greater than that of the pallet 77, the pallet 77 abuts against the platform before the end of its travel ( Figures 7-8 ).

Le moyen de détection d'obstacle présent à l'extrémité de la palette 77 le détecte et provoque l'arrêt de la sortie de la palette 77.The obstacle detection means present at the end of the pallet 77 detects it and stops the output of the pallet 77.

Dans un deuxième cas, illustré en figures 9 et 10, où la hauteur du quai 80 est inférieure à celle de la palette 77, la palette comble-lacune 77 se déplace transversalement jusqu'à la fin de sa course. Elle se trouve alors parallèle et au-dessus du quai 80. Lorsque la fin de course de la palette 77 est atteinte, la palette 77 pivote autour de l'axe longitudinal afin de former une pente douce entre la caisse 3 et le quai 80. Alors, la palette 77 pivote et vient buter contre le quai 80, situation représentée en figure 11.In a second case, illustrated in Figures 9 and 10 , where the height of the platform 80 is less than that of the pallet 77, the gap-gap pallet 77 moves transversely until the end of its stroke. It is then parallel and above the platform 80. When the end of travel of the pallet 77 is reached, the pallet 77 pivots around the longitudinal axis to form a gentle slope between the body 3 and the platform 80. Then, the pallet 77 pivots and abuts against the platform 80, a situation represented in figure 11 .

Le vantail 10 s'ouvre alors, permettant à tous les voyageurs, valides et à mobilité réduite, de sortir du véhicule ferroviaire.The leaf 10 opens then, allowing all the travelers, valid and with reduced mobility, to leave the railway vehicle.

En variante, le tiroir 63 est monté coulissant par rapport à la plateforme 18 et un organe élastique est interposé entre le tiroir 63 et la plateforme 18 pour solliciter élastiquement le tiroir obturateur contre le vantail 10. L'extrémité libre du tiroir 63 comporte une surface d'appui suiveuse appliquée contre la surface du vantail 10 et propre à glisser sur cette surface du vantail 10 en sollicitant le tiroir 63 à l'encontre de l'action de l'organe élastique.Alternatively, the slide 63 is slidably mounted relative to the platform 18 and a resilient member is interposed between the slide 63 and the platform 18 to resiliently urge the shutter slide against the leaf 10. The free end of the drawer 63 comprises a follower bearing surface applied against the surface of the leaf 10 and adapted to slide on this surface of the leaf 10 by biasing the slide 63 against the action of the elastic member.

En variante, non représentée sur les dessins annexés, la palette comble-lacune 77 est portée par la plateforme 18. Les rails 78, 79 sont alors disposés sous la plateforme 18, de telle sorte que la palette 77 est montée coulissante sur les rails 78, 79 et susceptible de se déplacer vers sa position sortie au travers de l'ouverture 9. La position sortie de la palette comble-lacune 77 implique alors au préalable une position ouverte du vantail 10.Alternatively, not shown in the accompanying drawings, the gap-gap pallet 77 is carried by the platform 18. The rails 78, 79 are then arranged under the platform 18, so that the pallet 77 is slidably mounted on the rails 78 , 79 and able to move to its extended position through the opening 9. The position of the exit pallet gap-gap 77 then implies beforehand an open position of the leaf 10.
