Abstract

The mobile vehicle sill consists of a base (23), designed to be fixed to the floor of the vehicle, and carrying a longitudinal mobile sill (22). The means for the displacement of the sill are also fitted to the base and consist of an adjustable length jack (56), which extends longitudinally, roughly parallel to the sill, and which is connected to the base and the sill by hinge assemblies (28A, 28B), which transform the movement of the jack into movement and displacement of the sill.

Description

La présente invention concerne un module de seuil mobile pour véhicule, destiné notamment à réduire une lacune entre une porte d'accès à un véhicule ferroviaire et un quai, et un agencement de ce module dans un véhicule ferroviaire.The present invention relates to a mobile threshold module for a vehicle, intended in particular to reduce a gap between an access door to a railway vehicle and a dock, and an arrangement of this module in a railway vehicle.

On connaít déjà dans l'état de la technique un module de seuil mobile pour véhicule, destiné notamment à réduire une lacune entre une porte d'accès à un véhicule ferroviaire et un quai, du type comprenant une embase, destinée à être fixée sur un plancher du véhicule, portant un seuil mobile longitudinal et des moyens de déplacement de ce seuil mobile, voir entre autres DE-AS-1 163 886 or DE-GM-94 03 982.We already know in the state of the art a mobile threshold module for vehicle, intended in particular to reduce a gap between a vehicle access door railway and a platform, of the type comprising a base, intended to be fixed on a floor of the vehicle, carrying a longitudinal movable threshold and moving means of this movable threshold, see inter alia DE-AS-1 163 886 or DE-GM-94 03 982.

Un véhicule ferroviaire équipant notamment une rame de métro comporte habituellement de larges portes d'accès, ménagée dans les parois latérales de ce véhicule, obturables par des vantaux coulissants ou louvoyants-coulissants. Le bord inférieur longitudinal d'une porte d'accès est délimité par une partie du plancher formant seuil. Lorsque le véhicule ferroviaire est à quai, le seuil des portes d'accès est parfois relativement éloigné du bord de ce quai libérant ainsi un espace ou lacune entre le seuil et le quai pouvant s'avérer dangereux pour les voyageurs franchissant la porte.A railway vehicle equipping in particular a subway train comprises usually wide access doors, formed in the side walls of this vehicle, can be closed by sliding or sliding-sliding leaves. The bottom edge longitudinal of an access door is delimited by a portion of the threshold floor. When the railway vehicle is at the dock, the threshold of the access doors is sometimes relatively far from the edge of this wharf thus releasing a gap or gap between the threshold and the wharf may be dangerous for travelers crossing the door.

On a donc proposé dans l'état de la technique de réduire ou supprimer cet espace indésirable entre le quai et le seuil d'une porte d'accès de véhicule ferroviaire en prolongeant ce seuil à l'aide de moyens fixes ou mobiles (escamotables lorsque le véhicule circule). Les moyens fixes de prolongement du seuil font saillie en permanence à l'extérieur du véhicule et risquent donc de heurter un obstacle anormalement proche des voies de circulation du véhicule ferroviaire. Les moyens mobiles de prolongement du seuil, comprenant par exemple un module du type précité, fonctionnent généralement suivant une cinématique complexe et sont relativement encombrants.It has therefore been proposed in the state of the art to reduce or eliminate this undesirable space between the platform and the threshold of a rail vehicle access door in extending this threshold using fixed or mobile means (retractable when the vehicle flows). The fixed means of extension of the threshold protrude permanently to the outside of the vehicle and may therefore hit an obstacle that is abnormally close to traffic lanes of the railway vehicle. The mobile means of extension of the threshold, comprising for example a module of the aforementioned type, generally operate following a complex kinematics and are relatively bulky.

L'invention a notamment pour but de réduire ou supprimer l'espace indésirable entre le quai et le seuil d'une porte d'accès de véhicule ferroviaire à l'arrêt le long de ce quai.The purpose of the invention is in particular to reduce or eliminate space undesired between the platform and the threshold of a railway vehicle access door stationary on along this wharf.

A cet effet, l'invention a pour objet un module du type précité, caractérisé en ce que les moyens de déplacement comportent un vérin de longueur réglable, s'étendant longitudinalement sensiblement parallèlement au seuil mobile, relié à l'embase et au seuil mobile par au moins un ensemble articulé transformant les variations de longueur du vérin en déplacements en translation du seuil mobile.For this purpose, the subject of the invention is a module of the aforementioned type, characterized in that the moving means comprise a cylinder of adjustable length, extending longitudinally substantially parallel to the movable threshold, connected to the base and the threshold mobile by at least one articulated assembly transforming the length variations of the jack in displacements in translation of the mobile threshold.

Suivant d'autres caractéristiques de ce module :

  • le seuil mobile comprend des moyens élastiques de rappel en position escamotée comportant au moins un ressort de traction reliant l'embase et ce seuil mobile ;
  • les moyens élastiques de rappel comprennent, pour chaque polygone articulé, au moins un ressort de traction, de préférence trois ressorts de traction, s'étendant entre les deux sommets libres de ce polygone articulé ;
  • les deux côtés consécutifs portant un sommet libre sont matérialisés par des ferrures formant bielles munies de charnons de réception de broches d'articulation matérialisant les sommets du polygone.
According to other features of this module:
  • the articulated assembly forms, in a plane substantially parallel to the longitudinal direction of the movable threshold and to the moving direction of this movable threshold, an articulated polygon provided with at least two consecutive sides comprising two non-consecutive vertices articulated on integral supports the base and the movable threshold, respectively, and a common free vertex displaceable parallel to the longitudinal direction of the movable threshold, connected to one end of the jack;
  • the polygon is a hexagon having two free vertices defining a longitudinal diagonal of the hexagon of variable length;
  • the moving threshold moving means comprise two articulated polygons having two close free peaks connected to both ends of the longitudinal cylinder;
  • the displacement means of the movable threshold comprise a first rod coupling the free vertex not connected to the jack of a first articulated polygon with the free vertex connected to this jack of the second articulated polygon, the free vertex connected to the jack of the first articulated polygon being mounted sliding freely in translation in a longitudinal guiding slot formed in the first rod, and a second rod coupling the free vertex not connected to the jack of the second articulated polygon with the free vertex connected to the jack of the first articulated polygon, the free vertex connected to the jack the second articulated polygon being mounted to slide freely in translation in a longitudinal guiding slot formed in the second bead wire;
  • the movable threshold comprises resilient return means in the retracted position comprising at least one traction spring connecting the base and the movable threshold;

L'invention a également pour objet un agencement d'un module tel que défini ci-dessus dans un véhicule ferroviaire comprenant un plancher muni d'un partie formant un seuil longitudinal fixe délimitant un bord inférieur longitudinal d'une porte d'accès au véhicule, caractérisé en ce que le seuil mobile est déplaçable en translation sensiblement transversalement à la direction longitudinale des seuils, entre une position escamotée sous le seuil fixe et une position saillante prolongeant de seuil fixe.The invention also relates to an arrangement of a module as defined above in a railway vehicle comprising a floor having a portion forming a a fixed longitudinal threshold delimiting a longitudinal lower edge of an access door to the vehicle, characterized in that the movable threshold is displaceable in translation substantially transversely to the longitudinal direction of the thresholds, between a position retracted under the fixed threshold and a protruding position prolonging fixed threshold.

Suivant une autre caractéristique de cet agencement, le vérin s'étend sous le seuil fixe.According to another characteristic of this arrangement, the jack extends under the fixed threshold.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins dans lesquels :

  • la figure 1 est une vue en élévation d'un véhicule ferroviaire dans lequel sont agencés des modules selon l'invention;
  • la figure 2 est une vue de détail, en coupe transversale, du seuil d'une porte d'accès au véhicule représenté sur la figure 1 ;
  • la figure 3 est une vue de dessus de la figure 2 montrant le seuil mobile en position saillante ;
  • la figure 4 est une vue en coupe suivant la ligne 4-4 de la figure 3 ;
  • la figure 5 est une vue similaire à la figure 3 montrant le seuil mobile en position escamotée.
The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the drawings in which:
  • Figure 1 is an elevational view of a railway vehicle in which are arranged modules according to the invention;
  • Figure 2 is a detail view, in cross section, of the threshold of a vehicle access door shown in Figure 1;
  • Figure 3 is a top view of Figure 2 showing the movable threshold in the projecting position;
  • Figure 4 is a sectional view taken along the line 4-4 of Figure 3;
  • Figure 5 is a view similar to Figure 3 showing the movable threshold in the retracted position.

On a représenté sur la figure 1 un véhicule ferroviaire 10 muni de modules M selon l'invention.FIG. 1 shows a railway vehicle 10 provided with modules M according to the invention.

Ce véhicule 10 comprend deux parois latérales 12, dont une seule est visible sur la figure 1, dans laquelle sont ménagées des portes 14 d'accès à l'intérieur du véhicule, par exemple au nombre de trois. Ces portes d'accès 14 sont obturables au moyen de vantaux louvoyants-coulissants 16 déplaçables le long de la paroi latérale 12 entre des positions de fermeture et d'ouverture de ces portes 14.This vehicle 10 comprises two side walls 12, only one of which is visible in FIG. 1, in which doors 14 are provided for access to the interior of the vehicle, for example three in number. These access doors 14 are closable by means of sliding-sliding leaves 16 movable along the side wall 12 between closing and opening positions of these doors 14.

On notera que dans ce qui précède et ce qui suit le terme "porte" désigne une ouverture dans une paroi du véhicule.Note that in what precedes and what follows the term "door" means a opening in a wall of the vehicle.

Sur la figure 2, on a représenté une plate-forme sensiblement horizontale formant un plancher 18 du véhicule 10. Ce plancher 18 comporte une partie formant un seuil longitudinal fixe 20 délimitant un bord inférieur longitudinal d'une porte d'accès 14.In Figure 2, there is shown a substantially horizontal platform forming a floor 18 of the vehicle 10. This floor 18 comprises a part forming a fixed longitudinal threshold 20 delimiting a longitudinal lower edge of an access door 14.

Le seuil fixe 20 est destiné à être prolongé, vers l'extérieur du véhicule 10 par un seuil longitudinal mobile 22, en forme générale de becquet, du module M. Ce module comporte une embase 23, portant le seuil mobile 22, fixée de façon connue en soi sur le plancher.The fixed threshold 20 is intended to be extended towards the outside of the vehicle 10 by a movable longitudinal threshold 22, in the general shape of spoiler, of the module M. This module comprises a base 23, carrying the movable threshold 22, fixed in a manner known per se on the floor.

Bien entendu, le véhicule 10 comporte autant de seuils fixes 20 et mobiles 22 que de portes d'accès 14, donc autant de modules M que de portes d'accès. Of course, the vehicle 10 comprises as many fixed and movable thresholds 22 than access doors 14, so as many modules M as access doors.

Le seuil mobile 22 est déplaçable en translation, sensiblement transversalement à la direction longitudinale des seuils 20, 22 entre une position escamotée sous le seuil fixe 20, telle que représentée sur la figure 5, et une position saillante prolongeant le seuil fixe 20, telle que représentée sur les figures 2 et 3. La direction de déplacement du seuil mobile 22 est représentée par une flèche F sur les figures 2, 3 et 5.The mobile threshold 22 is displaceable in translation, substantially transversely to the longitudinal direction of the thresholds 20, 22 between a position retracted under the fixed threshold 20, as shown in FIG. 5, and a position protruding extending the fixed threshold 20, as shown in Figures 2 and 3. The direction of movement of the movable threshold 22 is represented by an arrow F on the Figures 2, 3 and 5.

En se référant notamment à la figure 2, on voit que lorsque le seuil mobile 22 est en position saillante, ce dernier s'étend entre le seuil fixe 20 et un quai 24 de circulation des voyageurs, de manière à réduire autant que possible l'espace entre ce seuil mobile 22 et ce quai 24.Referring in particular to FIG. 2, it can be seen that when the moving threshold 22 is in projecting position, the latter extends between the fixed threshold 20 and a platform 24 of movement of passengers, so as to reduce as far as possible the space between this threshold mobile 22 and this dock 24.

Sur la figure 2 on a également représenté le vantail 16 d'obturation de la porte 14 associée aux seuils fixe 20 et mobile 22 dans une position ouverte (traits pleins), correspondant à la position saillante du seuil mobile 22 illustrée sur la figure 2, et dans une position fermée (traits mixtes), correspondant à la position escamotée du seuil mobile 22 illustrée sur la figure 5.FIG. 2 also shows the leaf 16 closing the door 14 associated with fixed thresholds 20 and movable 22 in an open position (solid lines), corresponding to the projecting position of the movable threshold 22 illustrated in FIG. 2, and in a closed position (mixed lines), corresponding to the retracted position of the moving threshold 22 shown in Figure 5.

Le seuil mobile 22 est déplaçable en translation de préférence à l'aide des moyens 26 logés sous le seuil fixe 20.The mobile threshold 22 is displaceable in translation preferably with the help of means 26 housed below the fixed threshold 20.

Ces moyens de déplacement 26 comprennent deux ensembles articulés formant chacun, dans un plan sensiblement parallèle à la direction longitudinale des seuils 20,22 et à la direction de déplacement du seuil mobile 22 (par exemple le plan des figures 3 et 5), un polygone articulé 28A,28B.These displacement means 26 comprise two articulated assemblies each forming in a plane substantially parallel to the longitudinal direction of the thresholds 20,22 and the direction of movement of the movable threshold 22 (for example the plane of the figures 3 and 5), an articulated polygon 28A, 28B.

On rappellera les définitions suivantes concernant un polygone.The following definitions for a polygon will be recalled.

Deux sommets d'un polygone sont dits consécutifs lorsqu'ils forment les extrémités d'un côté de ce polygone, et deux côtés d'un polygone sont dits consécutifs lorsqu'ils ont un sommet commun. Les diagonales d'un polygone sont les segments qui joignent deux sommets non consécutifs. Un polygone est convexe lorsque tous les points de ce polygone sont situés d'un même côté d'une droite joignant deux sommets consécutifs quelconques.Two vertices of a polygon are said to be consecutive when they form the ends of one side of this polygon, and two sides of a polygon are said to be consecutive when they have a common summit. The diagonals of a polygon are the segments that join two non-consecutive vertices. A polygon is convex when all points of this polygon are located on the same side of a line joining two vertices any consecutive.

Les polygones 28A,28B comportent des côtés articulés entre eux au niveau des sommets de ces polygones.The polygons 28A, 28B have sides articulated with each other at the level vertices of these polygons.

Dans l'exemple décrit, chaque polygone 28A,28B forme un hexagone convexe et comporte deux sommets 30A,30B,32A,32B, dits sommets libres, définissant une diagonale longitudinale (parallèle à la direction longitudinale des seuils 20,22) de longueur variable. Chaque sommet libre 30A,30B,32A,32B forme un sommet commun à deux côtés consécutifs 36A,36B,38A,38B,40A,40B,42A,42B. Ces deux côtés consécutifs comportent deux sommets non consécutifs 44A,44B,46A,46B,48A,48B,50A,50B articulés sur des supports 52A,52B,54A,54B solidaires de l'embrase 23 et du seuil mobile 22 respectivement. On notera que les supports 52A,52B,54A,54B forment des côtés longitudinaux opposés des polygones 28A,28B.In the example described, each polygon 28A, 28B forms a convex hexagon and has two vertices 30A, 30B, 32A, 32B, so-called free vertices, defining a longitudinal diagonal (parallel to the longitudinal direction of the thresholds 20,22) of variable length. Each free vertex 30A, 30B, 32A, 32B forms a vertex common to two consecutive sides 36A, 36B, 38A, 38B, 40A, 40B, 42A, 42B. These two consecutive sides have two non-consecutive vertices 44A, 44B, 46A, 46B, 48A, 48B, 50A, 50B articulated on supports 52A, 52B, 54A, 54B integral with the fuse 23 and the movable threshold 22 respectively. It will be noted that the supports 52A, 52B, 54A, 54B form sides opposite longitudinal axes of the polygons 28A, 28B.

Les sommets libres 30A,30B,32A,32B sont déplaçables parallèlement à la direction longitudinale des seuils 20,22, par déformation des polygones 28A,28B.The free apices 30A, 30B, 32A, 32B are movable parallel to the longitudinal direction of the thresholds 20, 22, by deformation of the polygons 28A, 28B.

En se référant à la figure 2, on voit que les deux côtés consécutifs d'un polygone 28A,28B portant un sommet libre 30A,30B,32A,32B sont matérialisés par des ferrures R formant bielles munies de charnons C de réception de broches d'articulation B matérialisant les sommets du polygone. Ces broches B s'étendent sensiblement perpendiculairement à un plan parallèle aux polygones.Referring to Figure 2, we see that the two consecutive sides of a polygon 28A, 28B bearing a free vertex 30A, 30B, 32A, 32B are materialized by fittings R forming rods provided with knuckles C for receiving articulation pins B materializing the vertices of the polygon. These pins B extend substantially perpendicular to a plane parallel to the polygons.

Les deux polygones articulés 28A,28B comportent deux sommets libres rapprochés 32A,32B reliés aux deux extrémités d'un vérin de longueur réglable. Ce vérin 56, de type classique, par exemple de type électrique, s'étend longitudinalement sensiblement parallèlement aux seuils 20, 22. Les variations de longueur du vérin 56 sont transformées en déplacements en translation du seuil mobile 22 dans la direction F grâce aux polygones articulés 28A, 28B.The two articulated polygons 28A, 28B comprise two free vertices close 32A, 32B connected to both ends of a cylinder of adjustable length. This cylinder 56, of conventional type, for example of the electric type, extends longitudinally substantially parallel to the thresholds 20, 22. The length variations of the jack 56 are transformed into displacements in translation of the movable threshold 22 in the direction F through articulated polygons 28A, 28B.

En variante, les moyens de déplacement 26 peuvent ne comporter qu'un seul polygone articulé relié à une extrémité du vérin, l'autre extrémité de ce vérin étant reliée à l'embase 23.In a variant, the displacement means 26 may comprise only one articulated polygon connected to one end of the jack, the other end of this jack being connected to the base 23.

Les deux polygone articulés 28A,28B sont reliés entre eux au moyen de deux tringles 58,60, superposées en considérant la figure 4. On notera, sur cette figure, que le vérin 56 s'étend entre ces deux tringles 58,60.The two articulated polygons 28A, 28B are interconnected by means of two 58,60 rods, superimposed considering Figure 4. It will be noted in this figure, that the cylinder 56 extends between these two rods 58,60.

Une première tringle 58 couple le sommet libre 32A non relié au vérin 56 d'un premier polygone articulé 28A avec le sommet libre 30B relié à ce vérin 56 du second polygone articulé 28B. Le sommet libre 30B relié au vérin 56 du premier polygone articulé 28A est monté coulissant librement en translation dans une lumière longitudinale de guidage 62 ménagée dans la première tringle 58.A first rod 58 couples the free vertex 32A not connected to the jack 56 of a first articulated polygon 28A with the free vertex 30B connected to this cylinder 56 of the second Articulated polygon 28B. The free vertex 30B connected to the jack 56 of the first polygon articulated 28A is mounted to slide freely in translation in a longitudinal lumen guide 62 formed in the first rod 58.

La seconde tringle 60 couple le sommet libre 32B non relié au vérin 56 du second polygone articulé 28B avec le sommet libre 30A relié au vérin 56 du premier polygone articulé 28A. Le sommet libre 30B relié au vérin 56 du second polygone articulé 28B est monté coulissant librement en translation dans une lumière longitudinale de guidage 64 ménagée dans la seconde tringle 60.The second rod 60 couples the free vertex 32B not connected to the jack 56 of the second articulated polygon 28B with the free vertex 30A connected to the cylinder 56 of the first Articulated polygon 28A. The free vertex 30B connected to the jack 56 of the second articulated polygon 28B is mounted to slide freely in translation in a longitudinal lumen of guide 64 formed in the second rod 60.

Le seuil mobile 22 est rappelé élastiquement en position escamotée à l'aide de moyens comprenant, de préférence, pour chaque polygone articulé 28A,28B, au moins un ressort de traction 66, par exemple trois ressorts de traction 66, s'étendant entre les deux sommets libres 30A,30B,32A,32B de ce polygone articulé 28A,28B. Les ressorts de traction 66 relient entre eux les supports 52A,52B,54A,54B des ensembles articulés.The movable threshold 22 is resiliently returned to the retracted position with the aid of means preferably comprising, for each articulated polygon 28A, 28B, at least one traction spring 66, for example three traction springs 66, extending between the two free vertices 30A, 30B, 32A, 32B of this articulated polygon 28A, 28B. The springs of Traction 66 interconnects the supports 52A, 52B, 54A, 54B articulated assemblies.

Le fonctionnement du seuil mobile 22 du véhicule ferroviaire selon l'invention est très simple.The operation of the mobile threshold 22 of the railway vehicle according to the invention is very simple.

Lorsque le véhicule 10 circule, le seuil mobile 22 est en position escamotée sous le seuil fixe 20, comme cela est représenté sur la figure 5. Le seuil mobile 22 épouse la forme générale externe de la paroi latérale 12 du véhicule. La longueur du vérin 56 est minimale.When the vehicle 10 is traveling, the mobile threshold 22 is in the retracted position below the fixed threshold 20, as shown in Figure 5. The mobile threshold 22 wife the general external shape of the side wall 12 of the vehicle. The length of the jack 56 is minimal.

On notera que le seuil mobile 22 a une forme générale creuse de manière à former un logement pour les moyens de déplacement 26, notamment lorsque ce seuil mobile 22 est en position escamotée.It will be noted that the mobile threshold 22 has a generally hollow shape so as to forming a housing for the moving means 26, especially when this threshold mobile 22 is in the retracted position.

Lorsque le véhicule 10 est à quai, pour permettre la montée ou la descente de voyageurs, le vérin 56 est actionné à l'aide de moyens de commande classiques de manière à atteindre sa longueur maximale comme cela est représenté sur la figure 3. Les polygones articulés 28A,28B transforment les déplacements longitudinaux des extrémités du vérin 56 en déplacements transversaux en translation du seuil mobile 22, de manière à placer ce dernier dans sa position saillante telle que représentée sur les figures 2 et 3. Une fois le vantail 16 ouvert, les voyageurs peuvent franchir la porte 14 en toute sécurité du fait que le seuil mobile 22 s'étend entre le seuil fixe 20 et le bord du quai 24.When the vehicle 10 is at the dock, to allow the ascent or descent of travelers, the jack 56 is actuated by means of conventional control means of in order to reach its maximum length as shown in FIG. Articulated polygons 28A, 28B transform the longitudinal displacements of the extremities of the jack 56 in transverse displacements in translation of the mobile threshold 22, so as to place the latter in its projecting position as shown in FIGS. 2 and 3. Once the leaf 16 is open, travelers can cross the door 14 in complete safety. the moving threshold 22 extends between the fixed threshold 20 and the edge of the platform 24.

Parmi les avantages de l'invention, on notera les suivants.Among the advantages of the invention, the following will be noted.

L'invention permet de réduire, voire de supprimer, l'espace indésirable entre le quai et le seuil fixe d'une porte d'accès d'un véhicule ferroviaire, ceci avec des moyens simples et peu encombrants (le vérin est logé sous le seuil fixe 22). Les ferrures R munies de charnons d'articulation C reliés entre eux par des broches B résistent efficacement au poids des voyageurs marchant sur le seuil mobile 22.The invention makes it possible to reduce or even eliminate the undesired space between the platform and the fixed threshold of an access door of a railway vehicle, this with simple and compact (the cylinder is housed under the fixed threshold 22). R fittings provided hinge knuckles C connected to each other by B-pins are effectively resistant to weight of passengers walking on the moving threshold 22.

Par ailleurs, en cas de panne, notamment électrique, le vérin électrique 56 peut être débrayé facilement à l'aide de moyens classiques, les ressorts de rappel 66 assurant le retour du seuil mobile 22 en position escamotée. Ces ressorts 66 permettent également un rattrapage automatique des jeux susceptibles d'apparaítre au niveau des articulations des polygones 28A,28B.Moreover, in the event of a breakdown, in particular electrical failure, the electric jack 56 can be easily disengaged using conventional means, the return springs 66 ensuring the return of the movable threshold 22 in the retracted position. These springs 66 also allow a automatic adjustment of the games likely to appear at the joints of the polygons 28A, 28B.

De plus, les tringles 58, 60 de couplage des polygones articulés 28A, 28B coordonnent efficacement les déformations de ces polygones.In addition, the rods 58, 60 for coupling the articulated polygons 28A, 28B effectively coordinate the deformations of these polygons.

Enfin, le module M, comportant l'embase 23 portant le seuil mobile 22 et les moyens 26 de déplacement de ce seuil 22, forme un tout qui peut être commercialisé indépendamment du véhicule. Ainsi, le module peut être monté sur des véhicules variés, ferroviaires ou non.Finally, the module M, comprising the base 23 carrying the movable threshold 22 and the means 26 for moving this threshold 22, forms a whole that can be marketed regardless of the vehicle. Thus, the module can be mounted on various vehicles, railways or not.
