Description

La présente invention concerne un emmarchement à marches escamotables pour porte d'accès et de sortie d'un véhicule ferroviaire de transport de voyageurs, à partir de ou vers des quais à au moins deux niveaux différents, comprenant une marche supérieure mobile sous l'effet d'un premier vérin entre une position rentrée à l'inté­rieur du véhicule et une position sortie horizontale proche d'un niveau supérieur de quai, et une marche inférieure mobile entre une position rentrée à l'intérieur du véhicule et une position sortie horizontale correspondant à un niveau inférieure de quai.The present invention relates to a step with retractable steps for access and exit door of a rail passenger vehicle, from or to platforms at at least two different levels, comprising an upper step movable under the effect a first jack between a position retracted inside the vehicle and a horizontal extended position close to an upper platform level, and a movable lower step between a position retracted inside the vehicle and a corresponding horizontal extended position at a lower platform level.

Il s'applique notamment à des véhicules ferroviaires destinés à circuler sur des réseaux, soit nationaux, soit internationaux, dont les hauteurs normalisées de quai au-dessus de la voie sont différentes.It applies in particular to rail vehicles intended to run on networks, either national or international, whose standardized platform heights above the track are different.

La demanderesse a fabriqué pour les wagons de la ligne à très grande vitesse Paris-Lyon un emmarchement comprenant une marche inférieure fixe et une marche supérieure mobile autour d'un axe horizontal entre une position rentrée à l'intérieur du wagon et une position sortie horizontale, sous l'effet d'un vérin agissant sur un polygone articulé relié à un bras faisant un angle fixe avec la surface de la marche mobile, à l'encontre de la résistance d'un ressort, jusqu'au dépassement d'une position de point mort au-delà de laquelle le ressort tend à maintenir la marche soit en position sortie, soit en position rentrée au repos.The plaintiff has manufactured for the wagons of the very high speed line Paris-Lyon a step comprising a fixed lower step and a movable upper step around a horizontal axis between a position returned inside the wagon and a position horizontal exit , under the effect of a jack acting on an articulated polygon connected to an arm making a fixed angle with the surface of the movable step, against the resistance of a spring, until a position is exceeded in neutral beyond which the spring tends to maintain walking either in the extended position or in the retracted position at rest.

Un tel emmarchement ne convient cependant pas pour permettre la montée et la descente des voyageurs à partir de, ou vers, des quais de hauteurs différentes au-dessus de la voie, dans des conditions de confort suffisantes pour la grande majorité du public, notamment pour les jeunes enfants ou les personnes âgées. En particulier, les projets de train à très grande vitesse pour le Nord de la France, destinés à emprunter les réseaux belges et anglais et le tunnel sous la Manche, imposent de prévoir des emmarchements entièrement escamotables, permettant au public de monter et de descendre facilement des voitures, avec des quais de gare plus élevés par rapport à ceux du réseau français de 210 mm pour le réseau belge et de 365 mm pour le réseau anglais, l'écartement entre le bord de la caisse du véhicule et le bord du quai étant par ailleurs notablement moindre pour le réseau anglais que pour les réseaux français et belge.However, such a step is not suitable for allowing passengers to get on and off from or to platforms of different heights above the track, in conditions of sufficient comfort for the vast majority of the public, in particular for young children or the elderly. In particular, the very high speed train projects for the North of France, intended to use the Belgian and English networks and the Channel Tunnel, require the provision of fully retractable steps, allowing the public to get on and off easily cars, with station platforms higher than those of the French network of 210 mm for the Belgian network and 365 mm for the English network, the spacing between the edge of the vehicle body and the edge of the platform being also significantly less for the English network than for the French and Belgian networks.

La présente invention a donc pour but de procurer un emmarche­ment à marches entièrement escamotables permettant un accès facile des wagons à la grande majorité du public dans des gares de niveaux de quai différents et à écartements entre profil des wagons et bord de quai différents, une marche inférieure ne dépassant pas l'écartement latéral de la marche supérieure en position sortie dans le cas de l'arrêt dans les gares présentant les quais les plus hauts, de façon à ne laisser subsister qu'un faible intervalle entre le bord de la marche supérieure et ces quais, tout en adaptant le profil du wagon à celui de tels quais. Il a encore pour but d'assurer une stabilité complète des marches dans leurs différentes positions, d'assurer la priorité de l'ouverture et de la fermeture de l'emmarchement par rapport à la porte, d'interdire l'ouverture de la porte si l'emmarchement ne s'ouvre pas et le démarrage de la rame si l'emmarchement reste en position ouverte, à la suite de pannes du dispositif de commande, tout en permettant alors une commande manuelle.The present invention therefore aims to provide a step with fully retractable steps allowing easy access of the wagons to the vast majority of the public in stations of different platform levels and with spacings between profile of the wagons and different platform edge, a step lower not exceeding the lateral spacing of the upper step in the extended position in the case of stopping in stations with the highest platforms, so as to leave only a small gap between the edge of the upper step and these platforms, while adapting the profile of the wagon to that of such platforms. It also aims to ensure complete stability of the steps in their different positions, to ensure the priority of the opening and closing of the step relative to the door, to prohibit the opening of the door if the step does not open and the start of the train if the step remains in the open position, following failures of the control device, while allowing manual control.

L'emmarchement selon l'invention est caractérisé en ce que :

  • A) le premier vérin d'entraînement de la marche supérieure agit sur deux palonniers d'axe vertical parallèles entraînant deux premiers chariots roulant sur des rails horizontaux jusqu'à des butées, à l'encontre de la résistance d'un ressort d'axe horizontal lié d'une part à un point fixe, d'autre part à un bras horizontal de l'un des palonniers, jusqu'à dépassement d'une position de point mort, les extrémités des bras correspondants des deux palonniers étant solidarisées par une tige de conjugaison, et
  • B) la marche inférieure est mobile,
    • a) entre la position rentrée à l'intérieur du véhicule et une première position sortie faisant contre-marche pour la marche supérieure en position sortie, sous l'effet du même vérin agissant sur les mêmes palonniers entraînant deux seconds chariots roulant sur des rails horizontaux jusqu'à des butées, à l'encontre de la résistance d'un ressort d'axe horizontal jusqu'à dépassement de sa position de point mort, les extrémités des bras correspondants des deux palonniers étant solidarisées par une tige de conjugai­son ; et
    • b) entre la première position sortie et une position horizontale correspondant à au moins un niveau inférieur de quai, sous l'effet d'un second vérin entraînant la rotation de cette marche inférieure autour de paliers horizontaux solidaires des seconds chariots et traversant l'extrémité inférieure de cette marche, jusqu'à une position de butée limitée par une bielle de retenue, à l'encontre de la résistance d'un ressort d'axe dans un plan vertical lié d'une part à un axe horizontal fixe, d'autre part à un bras susceptible de pivoter autour d'un axe horizontal, et solidarisé par une bielle avec un point de cette marche inférieure au-dessus de son palier horizontal, jusqu'à dépassement d'une position de point mort de ce dernier ressort.
The step according to the invention is characterized in that:
  • A) the first upper step drive cylinder acts on two parallel vertical axis spreaders driving two first carriages rolling on horizontal rails up to stops, against the resistance of an axis spring horizontal linked on the one hand to a fixed point, on the other hand to a horizontal arm of one of the spreaders, until a neutral position is exceeded, the ends of the corresponding arms of the two spreaders being secured by a conjugation stem, and
  • B) the bottom step is mobile,
    • a) between the retracted position inside the vehicle and a first extended position acting as a counter-step for the upper step in the extended position, under the effect of the same actuating cylinder on the same lifting beams driving two second carriages rolling on horizontal rails up to stops, against the resistance of a spring with a horizontal axis until it exceeds its neutral position, the ends of the corresponding arms two spreaders being secured by a connecting rod; and
    • b) between the first extended position and a horizontal position corresponding to at least one lower platform level, under the effect of a second jack causing the rotation of this lower step around horizontal bearings integral with the second carriages and passing through the end lower of this step, up to a stop position limited by a retaining rod, against the resistance of an axis spring in a vertical plane linked on the one hand to a fixed horizontal axis, on the other hand to an arm capable of pivoting about a horizontal axis, and secured by a connecting rod with a point of this lower step above its horizontal bearing, until a neutral position of this latter spring is exceeded .

Il répond en outre de préférence à au moins l'une des caractéristiques suivantes :
- la marche supérieure mobile est solidarisée avec au moins une biellette entraînant la rotation d'un support de joint de porte entre une position de fermeture et un position d'ouverture.
- Il est muni de détecteurs de position interdisant le départ de la rame en position non complètement rentrée des marches.
- Le nez de la marche inférieure mobile est munie de poignées permettant sa manoeuvre manuelle.It also preferably meets at least one of the following characteristics:
- The movable upper step is secured with at least one link causing the rotation of a door seal support between a closed position and an open position.
- It is fitted with position detectors preventing the train from leaving in the not fully retracted position.
- The nose of the mobile lower step is provided with handles allowing its manual operation.

Il est décrit ci-après, à titre d'exemple et en référence aux figures schématiques du dessin annexé, un emmarchement à marches escamotables convenant pour des wagons circulant sur des réseaux à trois hauteurs de quai différentes, telles que celles des quais des réseaux français, anglais et belge, selon l'invention.

  • La figure 1 représente en coupe verticale l'emmarchement en position rentrée, porte fermée, pendant la marche de la rame.
  • La figure 2 est un schéma fonctionnel en plan du vérin de commande, des palonniers, de deux des chariots qu'ils entraînent.
  • La figure 3 est une vue partielle également en plan de ce même vérin, de l'un des palonniers et de l'un des chariots correspon­dants, avec le ressort assurant la stabilité en position ouverte ou fermée des marches.
  • La figure 4 représente en coupe verticale l'emmarchement en position d'accès à un quai du niveau le plus élevé (par exemple quai du réseau anglais), porte ouverte, la marche supérieure seule étant accessible aux voyageurs et la marche inférieure lui servant de contre-marche.
  • La figure 5 représente en coupe verticale l'emmarchement en position d'accès à des quais d'un niveau inférieur, la marche inférieure étant au niveau d'un quai de hauteur intermédiaire (par exemple quai du réseau belge) et à mi-hauteur entre la marche supérieure et un quai de hauteur encore inférieure (par exemple quai du réseau français).
  • La figure 6 est une vue analogue à celle de la figure 5, montrant le ressort assurant le maintien de la marche inférieure en position, soit de contre-marche, soit horizontale pour l'accès un quai de niveau inférieur.
It is described below, by way of example and with reference to the schematic figures of the accompanying drawing, a step with retractable steps suitable for wagons running on networks at three different platform heights, such as those of the platforms of French networks , English and Belgian, according to the invention.
  • Figure 1 shows in vertical section the step in the retracted position, door closed, while the train is running.
  • FIG. 2 is a functional diagram in plan of the control jack, spreaders, two of the carriages they drive.
  • FIG. 3 is a partial plan view also of this same jack, of one of the lifting beams and of one of the corresponding carriages, with the spring ensuring the stability in the open or closed position of the steps.
  • FIG. 4 shows in vertical section the step in the access position to a platform of the highest level (for example platform of the English network), door open, the upper step alone being accessible to travelers and the lower step serving it counter step.
  • Figure 5 shows in vertical section the step in the access position to docks of a lower level, the bottom step being at a quay of intermediate height (for example quay of the Belgian network) and halfway up between the upper step and an even lower platform (eg platform on the French network).
  • Figure 6 is a view similar to that of Figure 5, showing the spring ensuring the maintenance of the lower step in position, either counter-step, or horizontal for access to a lower level platform.

Dans la figure 1, comme dans les figures 4, 5 et 6, sont représentés trois niveaux de quai, 1 (par exemple du réseau anglais), 2 (par exemple du réseau belge) et 3 (par exemple du réseau français) et le plancher 4 du véhicule en face de la porte 5. La porte d'accès étant fermée, la marche supérieure 6 est rentrée à l'intérieur de la caisse et la marche inférieure 7 prolonge vers le bas la porte par sa surface inférieure.In Figure 1, as in Figures 4, 5 and 6, three platform levels are represented, 1 (for example from the English network), 2 (for example from the Belgian network) and 3 (for example from the French network) and the vehicle floor 4 opposite the door 5. The access door being closed, the upper step 6 is tucked inside the body and the lower step 7 extends the door downwards by its lower surface.

A l'intérieur et sous le plancher en face de la porte est disposé le châssis 8 comprenant quatre arbres de guidage tels que 9 pour des chariots tels que 10 et 11, ainsi que deux palonniers, dont seul l'un 12 est visible. Le vérin pneumatique horizontal 13 est porté par un support 13A, et l'extrémité de sa tige est reliée par un bras 14A à l'axe du palonnier 12.Inside and under the floor in front of the door is arranged the frame 8 comprising four guide shafts such as 9 for carriages such as 10 and 11, as well as two lifting beams, of which only one 12 is visible. The horizontal pneumatic cylinder 13 is carried by a support 13A, and the end of its rod is connected by an arm 14A to the axis of the lifter 12.

Ce palonnier entraîne le chariot 10 par l'intermédiaire d'un galet 15 glissant dans un guide 15A et le chariot 11 par l'intermédiaire d'un galet 16 glissant dans un guide 16A.This lifter drives the carriage 10 via a roller 15 sliding in a guide 15A and the carriage 11 via a roller 16 sliding in a guide 16A.

La commande du vérin 13 entraîne une rotation des palonniers 12, 40 (figure 2) dont les bras munis des galets tels que 15, 15B glissent sur le guide 15A, solidaire des chariots 9 et 10, leur imprimant un mouvement de translation vers la gauche de la figure. Les tiges de conjugaison telles que 17 (figure 2), liée aux bras 14B du palonnier 12 et 41 du palonnier 40, assurent la synchronisation des mouvements des palonniers 12 et 40. Les chariots sont amenés en butée sur les butoirs 18 et 18A, dont la position est réglable, après une course d'environ 110 mm, et repoussent hors de la caisse du véhicule les marches 6 et 7. La marche 6 entraîne alors par l'intermédiaire de deux biellettes, dont seule l'une 20 est visible, la rotation du volet 21 support du joint de porte 22, qui dégage l'ouverture de la porte et libère la surface totale de la marche 6, qui permet alors la descente sur le quai 1 ou la montée à partir de celui-ci. La marche 7, repoussée comme la marche 6, mais dont le fond reste parallèle à la paroi du wagon, forme alors contre­marche, en supportant la butée 39 solidaire de la marche 6 (figure 4).The actuator of the actuator 13 causes a rotation of the lifting beams 12, 40 (FIG. 2) whose arms provided with rollers such as 15, 15B slide on the guide 15A, integral with the carriages 9 and 10, imparting a translational movement to the left of the figure. The conjugation rods such as 17 (FIG. 2), linked to the arms 14B of the spreader 12 and 41 of the spreader 40, ensure the synchronization of the movements of the spreaders 12 and 40. The carriages are brought into abutment on the buffers 18 and 18A, of which the position is adjustable, after a stroke of approximately 110 mm, and pushes the steps 6 and 7 out of the vehicle body. The step 6 then drives via two links, only one of which is visible, the rotation of the flap 21 supporting the door seal 22, which releases the opening of the door and frees the total surface of the step 6, which then allows the descent on the platform 1 or the ascent from the latter. Step 7, pushed back like step 6, but whose bottom remains parallel to the wall of the wagon, then forms a riser, supporting the stop 39 integral with step 6 (Figure 4).

Le maintien en positions rentrée ou sortie de la marche supé­rieure 6 est assuré grâce au ressort 30 (figures 2-3). Celui-ci est fixé d'une part à un point fixe 31 solidaire du châssis 8 fixe, d'autre part à un point 32 du bras 14B du palonnier 12. Dans la position 30, il maintient la marche en position rentrée. Après rotation du palonnier 12 amenant le galet 15 du chariot 10 dans la position 15C, il prend la position 30A, dépassant la position de point mort par rapport à l'axe du palonnier 12, et maintient la marche 6 en position sortie. Le maintien en position rentrée ou sortie de la marche 7 est assuré par le même ressort, ou par un ressort analogue au niveau des chariots inférieurs tels que 11.Maintaining in the retracted or exited positions of the upper step 6 is ensured by means of the spring 30 (Figures 2-3). This is fixed on the one hand to a fixed point 31 secured to the fixed frame 8, on the other hand to a point 32 of the arm 14B of the lifter 12. In position 30, it maintains the step in the retracted position. After rotation of the lifter 12 bringing the roller 15 of the carriage 10 to the position 15C, it takes the position 30A, exceeding the neutral position relative to the axis of the lifter 12, and maintains the step 6 in the extended position. Maintaining the retracted or exiting position of the step 7 is ensured by the same spring, or by a similar spring at the level of the lower carriages such as 11.

Lorsque la rame doit s'arrêter dans un gare dont le quai est à un niveau inférieur 2 ou 3 (réseaux belge ou français), les marches 6 et 7 subissent en premier lieu la translation décrite ci-dessus, puis la marche inférieure 7 est mise en position d'accès ou de sortie comme suit.When the train has to stop at a station whose platform is at a lower level 2 or 3 (Belgian or French networks), the steps 6 and 7 undergo first the translation described above, then the lower step 7 is entry or exit position as follows.

Le vérin pneumatique 23, relié d'une part au point fixe 24 solidaire du châssis 8, d'autre part au point 25 de la zone médiane de la marche 7, fait pivoter cette dernière autour de paliers tels que 26, cette rotation étant limitée par deux bielles telles que 27 reliant le point 25 de la marche à un point fixe 28 du châssis 8, de façon que la surface supérieure de la marche 7 devienne horizontale, au niveau du quai 2. La marche 7 permet alors un accès à niveau au quai 2 et sert de marche intermédiaire pour l'accès au quai 3 (figure 5).The pneumatic cylinder 23, connected on the one hand to the fixed point 24 integral with the chassis 8, on the other hand at point 25 of the middle zone of the step 7, makes the latter pivot around bearings such as 26, this rotation being limited by two connecting rods such as 27 connecting the point 25 of the step to a fixed point 28 of the chassis 8, so that the upper surface of the step 7 becomes horizontal, at the platform 2. The step 7 then allows level access to the platform 2 and serves as an intermediate step for access to the platform 3 (Figure 5).

La stabilité de la marche inférieure 7 en position relevée ou horizontale est assurée grâce au ressort 33 (figure 6), fixé d'une part à l'axe fixe 34, d'autre part à l'extrémité d'un bras 35, pivotant autour d'un axe 36 et dont l'extrémité est reliée par une bielle 37 à un point 38 solidaire de la marche 7. Dans la posi­tion 33, il maintient la marche en position relevée. Dans la position 33A, après dépassement de la position de point mort par rapport à l'axe 36, il la maintient en position horizontale.The stability of the bottom step 7 in the raised or horizontal position is ensured by the spring 33 (FIG. 6), fixed on the one hand to the fixed axis 34, on the other hand at the end of an arm 35, pivoting around an axis 36 and the end of which is connected by a connecting rod 37 to a point 38 integral with the step 7. In position 33, it maintains the step in the raised position. In position 33A, after passing the neutral position relative to the axis 36, it maintains it in a horizontal position.

La fermeture de l'emmarchement est obtenue par les manoeuvres inverses des précédentes, sous l'effet de la manoeuvre des vérins 23 pour le relevage de la marche inférieure 7, puis 13 pour le retour des marches 6 et 7 à l'intérieur de la caisse du véhicule. En position de circulation de la rame, la marche inférieure 7 est appuyée sur les butées 39 solidaire de la marche supérieure 6 et 40 solidaire du châssis 8.The closing of the step is obtained by the reverse maneuvers of the previous ones, under the effect of the actuation of the jacks 23 for the raising of the bottom step 7, then 13 for the return of the steps 6 and 7 inside the vehicle body. In the train running position, the bottom step 7 is supported on the stops 39 secured to the top step 6 and 40 secured to the chassis 8.

Afin de permettre la manoeuvre de la marche 7 en cas de panne d'air comprimé, un certain espace est maintenu entre la face inférieure de la marche supérieure 6 et le nez de la marche inférieure 7 en position rentrée, grâce à des cales 39, 40. Le nez de cette marche est muni de deux poignées de commande manuelle, non représentées. La marche 6 est également munie des poignées de commande manuelles.In order to allow the operation of the step 7 in the event of a compressed air failure, a certain space is maintained between the lower face of the upper step 6 and the nose of the lower step 7 in the retracted position, thanks to shims 39, 40. The nose of this step is provided with two manual control handles, not shown. Step 6 is also equipped with manual control handles.

Pour éviter tout risque d'accident en cas de non-fonction­nement du retour de l'emmarchement en position fermée, compte tenu des différences de gabarit des tunnels des différents réseaux, l'emmarchement est muni de capteurs de position n'autorisant le démarrage de la rame qu'en position rentrée. Par contre, un blocage de l'emmarchement n'interdit pas l'ouverture manuelle de la porte.To avoid any risk of accident in the event of non-operation of the return of the step in the closed position, given the differences in the size of the tunnels of the different networks, the step is equipped with position sensors that do not allow the start of the train only in the retracted position. On the other hand, blocking the step does not prevent the manual opening of the door.
