Description

La présente invention concerne une structure de marchepieds pour véhicules ferroviaires ou routiers, en général, et porte, plus particulièrement, sur un dispositif de commande du déplacement d'une marche articulée d'accès à un véhicule et sur un dispositif d'accès à un véhicule, notamment ferroviaire, comportant un tel dispositif de commande.The present invention relates to a step structure for vehicles railway or road, in general, and relates, more particularly, to a device for control of the movement of an articulated step for access to a vehicle and on a device for accessing a vehicle, in particular a rail vehicle, comprising such a ordered.

Les dispositifs d'accès à un véhicule de l'art antérieur nécessitent la mise en oeuvre d'une marche mobile.Access devices to a vehicle of the prior art require the implementation work of a mobile step.

Une telle solution de l'art antérieur présente l'inconvénient majeur de devoir motoriser la marche mobile.Such a solution of the prior art has the major drawback of having to motorize the mobile step.

Le document DE 94 03 982 montre un dispositif d'accès à un véhicule ferroviaire. Ce dispositif d'accès est articulé et se rétracte sous l'effet d'une poussée horizontale induite par les vantaux de porte, en fin de phase de fermeture de ces vantaux, le dispositif d'accès sortant automatiquement à l'ouverture des vantaux de porte.Document DE 94 03 982 shows a vehicle access device rail. This access device is articulated and retracts under the effect of a push horizontal induced by the door leaves, at the end of the closing phase of these leaves, the access device coming out automatically when the door leaves are opened.

Pour ce faire, le dispositif d'accès à un véhicule provoque un mouvement de rentrée et de sortie de la marche d'accès en utilisant le louvoiement de la porte et les efforts induits par la porte.To do this, the vehicle access device causes a movement of entering and exiting the access step using the wiggling of the door and the efforts induced by the door.

Un but de l'invention est de fournir un dispositif de commande de déplacement d'une marche articulée d'accès à un véhicule et un dispositif d'accès à un véhicule, notamment ferroviaire, dont la conception générale permet un fonctionnement en toute sécurité, et dont la structure est simple et peu encombrante.An object of the invention is to provide a movement control device an articulated access step to a vehicle and a vehicle access device, especially rail, whose general design allows full operation safety, and whose structure is simple and compact.

Elle a donc pour objet un dispositif de commande du déplacement d'une marche articulée d'accès à un véhicule, le dispositif comportant un bras de commande, un bras intermédiaire et un bras de sortie ou de rentrée de la marche d'accès articulée, ledit dispositif de commande provoquant un mouvement de rentrée et de sortie de ladite marche d'accès articulée en utilisant le mouvement de louvoiement de la porte d'accès dudit véhicule et les efforts induits par ladite porte d'accès, une première extrémité F du bras de commande étant en appui contre l'un des vantaux en position rentrée de la marche, ledit bras intermédiaire étant monté à rotation par l'une de ses extrémités sur une deuxième extrémité E du bras de commande, ledit bras de sortie ou de rentrée de la marche articulée étant monté à rotation par l'une de ses extrémités B sur la marche articulée, ledit dispositif de commande comportant au moins un ressort sollicitant la marche à l'état sortie, caractérisé en ce que ledit bras de sortie ou de rentrée de ladite marche articulée est monté à rotation par l'autre de ses extrémités C sur le châssis du véhicule et comporte deux demis bras articulés par leur extrémité D se faisant face, ledit bras intermédiaire étant monté à rotation par l'une de ses extrémités aux extrémités D desdits deux demis bras constituant ledit bras de sortie ou de rentrée se faisant face, lesdits ressorts étant maintenus par leur extrémité supérieure G à un élément de poutre fixé à la caisse du véhicule et étant monté par leur autre extrémité aux extrémités D desdits deux demis bras constituant ledit bras de sortie ou de rentrée se faisant face, ladite marche étant articulée à son extrémité basse O et lesdits deux demis bras constituant ledit bras de sortie ou de rentrée étant susceptibles de s'arc-bouter sous l'effet dudit ressort de manière à bloquer par arc-boutement ladite marche articulée lorsqu'elle est en position sortie.It therefore relates to a device for controlling the movement of a step articulated vehicle access, the device comprising a control arm, an arm intermediate and an exit or re-entry arm of the articulated access step, said control device causing a movement in and out of said articulated access step using the wiggle movement of the access door of said vehicle and the forces induced by said access door, a first end F of the control arm bearing against one of the leaves in the retracted position of the step, said intermediate arm being rotatably mounted by one of its ends on a second end E of the control arm, said output or re-entry arm of the articulated step being rotatably mounted by one of its ends B on the step articulated, said control device comprising at least one spring biasing the operating in the extended state, characterized in that said outlet or re-entry arm of said articulated step is rotatably mounted by the other of its ends C on the chassis of the vehicle and comprises two half-arms articulated by their ends D facing each other, said intermediate arm being rotatably mounted by one of its ends at the ends D said two half-arms constituting said exit or re-entry arm facing each other, said springs being held by their upper end G to a beam element fixed to the body of the vehicle and being mounted by their other end at the ends D said two half-arms constituting said facing outward or backwardward arm, said step being articulated at its lower end O and said two half arms constituting said exit or re-entry arms being capable of bracing under the effect of said spring so as to block by bracing said articulated step when it is in position exit.

Le dispositif de commande d'une marche articulée d'accès à un véhicule selon l'invention satisfait également à l'une au moins des caractéristiques suivantes:

  • ledit bras de commande est monté pivotant à l'extrémité A du seuil fixe de la porte d'accès,
  • lesdits bras sont des bielles,
  • lesdits bras sont des cames.
The device for controlling a hinged access step to a vehicle according to the invention also satisfies at least one of the following characteristics:
  • said control arm is pivotally mounted at the end A of the fixed threshold of the access door,
  • said arms are connecting rods,
  • said arms are cams.

Un avantage du dispositif selon l'invention est sa simplicité, sa fiabilité, son faible coût, son absence de motorisation, son faible encombrement, sa maintenance aisée.An advantage of the device according to the invention is its simplicity, its reliability, its low cost, its absence of motorization, its small size, its easy maintenance.

Un autre avantage du dispositif selon l'invention est qu'il ne comporte pas d'élément "FUSIBLE" sur le nez de marche.Another advantage of the device according to the invention is that it does not include "FUSE" element on the stair nosing.

Un autre avantage du dispositif selon l'invention est la synchronisation des mouvements de la porte et de la marche articulée.Another advantage of the device according to the invention is the synchronization of door movements and articulated step.

Un autre avantage du dispositif selon l'invention est qu'il est très sécuritaire, à savoir :

  • il sort dès le début du déboítement de la porte, c'est-à-dire avant que les passagers ne puissent sortir,
  • il se ferme après le coulissement des vantaux, c'est-à-dire alors que les voyageurs sont bien descendus de cette marche articulée,
  • la marche articulée, lorsqu'elle est en position sortie, est bloquée par arc-boutement des leviers sous l'effet du ressort et ne peut de ce fait rentrer intempestivement,
  • en cas de rupture de l'un des ressorts, celui qui est disposé à l'autre bout de la marche articulée est suffisant pour assurer la sortie de la marche articulée (cas de la porte double).
Another advantage of the device according to the invention is that it is very safe, namely:
  • it leaves from the start of the dislocation of the door, that is to say before the passengers can leave,
  • it closes after the sliding of the leaves, that is to say when the travelers are well descended from this articulated step,
  • the articulated step, when it is in the extended position, is blocked by bracing of the levers under the effect of the spring and cannot therefore inadvertently return,
  • in the event of one of the springs breaking, the one at the other end of the articulated step is sufficient to ensure the exit from the articulated step (case of the double door).

D'autres caractéristiques et avantages de l'invention apparaítront à la lecture qui va suivre de la description, faite en référence aux dessins annexés sur lesquels:

  • la figure 1 est une vue de profil en coupe partielle d'une porte d'accès d'un véhicule ferroviaire dont le palier est équipé d'un dispositif d'accès conforme à l'invention, le dispositif d'accès au véhicule étant en position rétractée,
  • la figure 2 est une vue d'une partie de la porte de la figure 1 dans laquelle le dispositif d'accès au véhicule est en position active déployée,
  • les figures 3 et 4 représentent, à plus grande échelle, le dispositif d'accès au véhicule des figures 1 et 2, respectivement.
Other characteristics and advantages of the invention will appear on reading the following description, made with reference to the accompanying drawings in which:
  • Figure 1 is a partial sectional side view of an access door of a rail vehicle whose bearing is equipped with an access device according to the invention, the vehicle access device being in retracted position,
  • FIG. 2 is a view of part of the door of FIG. 1 in which the vehicle access device is in the deployed active position,
  • Figures 3 and 4 show, on a larger scale, the vehicle access device of Figures 1 and 2, respectively.

La figure 1 est une vue de profil en coupe partielle d'une porte d'accès 1 d'un véhicule ferroviaire dont le palier 2 est équipé d'un dispositif d'accès 3 au véhicule 4 conforme à l'invention.Figure 1 is a partial sectional side view of an access door 1 of a railway vehicle whose level 2 is equipped with an access device 3 to the vehicle 4 according to the invention.

Le dispositif d'accès 3 au véhicule 4 est disposé sous le seuil fixe 5 de la porte d'accès 1 et est en position rentrée.The vehicle access device 3 4 is disposed under the fixed threshold 5 of the door access 1 and is in the retracted position.

Le dispositif d'accès 3 au véhicule 4 est articulé de manière à se rétracter sous l'effet d'une poussée horizontale induite par les vantaux 6 de la porte 1, en fin de phase de fermeture de ces vantaux 6 de la porte 1.The access device 3 to the vehicle 4 is articulated so as to retract under the effect of a horizontal thrust induced by the leaves 6 of door 1, at the end of the closing of these leaves 6 of door 1.

Le dispositif d'accès 3 au véhicule 4 sort automatiquement à l'ouverture des vantaux 6 de porte 1.The access device 3 to the vehicle 4 automatically exits when the door leaves 6 1.

Le dispositif d'accès 3 au véhicule 4 comprend, dans l'espace disponible sous le seuil fixe 5 de la porte d'accès 1, une marche 7 articulée à son extrémité basse 0.The access device 3 to the vehicle 4 comprises, in the space available under the fixed threshold 5 of the access door 1, a step 7 articulated at its lower end 0.

La marche articulée 7 est ainsi susceptible de combler, en position sortie, de l'ordre de 70% de la lacune 8 entre le seuil 5 de la porte d'accès 1 et le quai 9.The articulated step 7 is thus capable of filling, in the extended position, with around 70% of the gap 8 between threshold 5 of access door 1 and platform 9.

Il est clair que le pourcentage de la lacune comblée varie en fonction de la valeur même de la lacune.It is clear that the percentage of the gap filled varies according to the very value of the gap.

La figure 2 correspond à la vue de profil en coupe partielle de la figure 1 dans laquelle le dispositif d'accès au véhicule est en position sortie.Figure 2 corresponds to the partial sectional profile view of Figure 1 in which the vehicle access device is in the extended position.

Le dispositif d'accès au véhicule comprend :

  • la marche articulé 7 capable de supporter les charges induites par les voyageurs et par les chariots et
  • deux dispositifs de commande 10 à bielles ou à cames, conjugués, provoquant les mouvements de rentrée et de sortie de la marche articulée 7.
The vehicle access device includes:
  • the articulated step 7 capable of supporting the loads induced by the travelers and by the carriages and
  • two control devices 10 with rods or cams, combined, causing the movements in and out of the articulated step 7.

Chacun de ces dispositifs de commande 10 est muni d'un bras de commande 12, d'un bras intermédiaire 11 et d'un bras de sortie ou de rentrée 13 de la marche articulée 7.Each of these control devices 10 is provided with a control arm 12, an intermediate arm 11 and an exit or re-entry arm 13 of the articulated step 7.

Le bras de commande 12 est monté pivotant à l'extrémité A du seuil fixe 5 de la porte d'accès 1.The control arm 12 is pivotally mounted at the end A of the fixed threshold 5 of the access door 1.

Le bras de sortie ou de rentrée 13 de la marche articulée 7 est monté libre en rotation, par l'une de ses extrémités libres B, sur la marche articulée 7 et est également monté libre en rotation par l'autre de ses extrémités C sur le châssis du véhicule ferroviaire.The exit or re-entry arm 13 of the articulated step 7 is mounted free in rotation, by one of its free ends B, on the articulated step 7 and is also freely mounted in rotation by the other of its ends C on the vehicle chassis rail.

Le bras de sortie ou de rentrée 13 de la marche articulée 7 comporte, par exemple, deux demis bras articulés c'est à dire solidaires entre eux et montés libres en rotation par leurs extrémités D se faisant faces.The exit or re-entry arm 13 of the articulated step 7 comprises, by example, two articulated half arms, that is to say integral with each other and mounted free in rotation by their ends D facing each other.

Le bras intermédiaire 11 est monté libre en rotation par l'une de ses extrémités sur les extrémités D du bras de sortie ou de rentrée 13 se faisant face et est monté à rotation par l'autre de ses extrémités sur l'une des extrémités E du bras de commande 12.The intermediate arm 11 is mounted to rotate freely at one of its ends on the ends D of the exit or re-entry arm 13 facing each other and is mounted at rotation by the other of its ends on one of the ends E of the control arm 12.

Dans la position représentée sur la figure 1, l'autre extrémité F du bras de commande 12 est en appui de façon libre en rotation, contre l'un des vantaux 6 de la porte 1.In the position shown in Figure 1, the other end F of the arm control 12 is free to press against one of the leaves 6 of the door 1.

Les dispositifs de commande 10 à bielles ou à cames comportent chacun au moins un ressorts 14 assurant l'automatisme des mouvements, et, plus particulièrement, sollicite la marche à l'état sortie.The control devices 10 with connecting rods or cams each comprise at minus a spring 14 ensuring the automation of the movements, and, more particularly, requests walking in the output state.

En effet, les ressorts 14 sont maintenus par leur extrémité supérieure G à un élément de poutre fixé à la caisse du véhicule 4 et sont montés à rotation par leur autre extrémité H aux extrémités D du bras de sortie ou de rentrée 13 se faisant face.Indeed, the springs 14 are held by their upper end G at a beam element fixed to the body of the vehicle 4 and are rotatably mounted by their other end H at the ends D of the exit or re-entry arm 13 facing each other.

La marche articulée 7, lorsqu'elle est en position sortie, est bloquée par arc-boutement des deux demis bras constituant le bras de sortie ou de rentrée 13 sous l'effet du ressort et ne peut de ce fait rentrer intempestivement.The articulated step 7, when in the extended position, is blocked by bracing of the two half-arms constituting the exit or re-entry arm 13 under the effect of the spring and cannot therefore return unexpectedly.

Le nombre de ressorts 14 et les efforts déployés par ces ressorts 14 sont principalement dépendants de la masse de la marche articulé 7, des frottements et des efforts induits par le dispositif d'accès 3 sur les vantaux 6 de la porte 1.The number of springs 14 and the forces exerted by these springs 14 are mainly dependent on the mass of the articulated step 7, friction and forces induced by the access device 3 on the leaves 6 of the door 1.

Le principe de fonctionnement du dispositif d'accès va maintenant être exposée en référence aux figures 3 et 4, lesquelles représentent le dispositif d'accès au véhicule des figures 1 et 2, respectivement.The operating principle of the access device will now be explained with reference to Figures 3 and 4, which show the vehicle access device Figures 1 and 2, respectively.

Rentrée de la marche articulée 7: Return from articulated step 7:

En fin de phase de fermeture de la porte 1 (phase de louvoiement), les vantaux 6 entrent en contact avec l'extrémité F des bras de commande 12 rotatifs du dispositif d'accès 3.At the end of the door 1 closing phase (weaving phase), the leaves 6 come into contact with the end F of the rotary control arms 12 of the device access 3.

La poussée induite par les vantaux 6 provoque la rotation de ces bras de commande 12 qui entraínent mécaniquement la rentrée la marche articulée 7.The thrust induced by the leaves 6 causes the rotation of these arms of control 12 which mechanically drives reentry the articulated step 7.

Sortie la marche articulée 7:Exit articulated step 7:

En début de phase d'ouverture de la porte 1 (phase de louvoiement), les vantaux 6 libèrent la poussée exercée sur les bras de commande 12.At the start of the door 1 opening phase (weaving phase), the leaves 6 release the thrust exerted on the control arms 12.

Cette action, couplée à celle induite par les ressorts de rappel 14, provoque la rotation automatique des bras de commande 12 qui entraínent mécaniquement la sortie de la marche articulée 7.This action, coupled with that induced by the return springs 14, causes the automatic rotation of the control arms 12 which mechanically drive the output of the articulated step 7.

Dans le cas où le seuil d'accès au véhicule ne comporte qu'une porte simple, les caractéristiques de l'unique ressort de rappel sont doublées.In the case where the vehicle access threshold has only a single door, the features of the unique return spring are doubled.
