Abstract

The car (2) has a case (4), an access door (8), a floor (6), and an access system (10) to access the car by the access door. The access system includes a chassis (18) rotatably mounted relative to the case along a horizontal axis (X), and a threshold (17) extending from the floor and rotatably mounted relative to the floor about another horizontal axis (Y), where the former axis is offset from the latter axis. The threshold rests on the chassis so that the rotation of the chassis about the former axis causes rotation of the threshold around the latter axis.

Description

La présente invention concerne une voiture de véhicule ferroviaire comprenant une caisse, une porte d'accès, un plancher et un système d'accès pour accéder à la voiture par la porte d'accès, ledit système d'accès comprenant un châssis monté rotatif par rapport à la caisse selon un premier axe sensiblement horizontal,The present invention relates to a rail vehicle car comprising a body, an access door, a floor and an access system for accessing the car through the access door, said access system comprising a frame rotatably mounted by relative to the body in a first substantially horizontal axis,

Le domaine de l'invention se rapporte aux véhicules ferroviaires, et plus particulièrement aux systèmes d'accès équipant les voitures de véhicules ferroviaires.The field of the invention relates to railway vehicles, and more particularly to access systems fitted to railway carriages.

Afin de faciliter la montée et la descente des voitures, notamment lorsque le véhicule ferroviaire se trouve à quai et qu'une lacune, c'est-à-dire un espace, existe entre la voiture et le quai, il est connu de munir les voitures de systèmes d'accès capables de s'incliner pour compenser au moins la lacune verticale, et ainsi réduire la marche formée entre le quai et la voiture.In order to facilitate the ascent and descent of the cars, especially when the railway vehicle is at the quay and a gap, that is to say a gap, exists between the car and the quay, it is known to provide the access systems cars capable of tilting to compensate for at least the vertical gap, and thus reduce the step formed between the dock and the car.

On connaît ainsi de FR 2 976 891 une voiture de véhicule ferroviaire comportant un système d'accès comprenant un caisson rotatif dont la surface supérieure forme, conjointement à un marchepied coulissant dans le caisson, une rampe d'accès entre la voiture et le quai.We thus know FR 2 976 891 a rail vehicle car comprising an access system comprising a rotary box whose upper surface forms, together with a sliding step in the box, a ramp between the car and the dock.

Toutefois, le système d'accès en question présente un inconvénient.However, the access system in question has a disadvantage.

En effet, le caisson est particulièrement volumineux. Ainsi, pour que sa rotation puisse être autorisée, la partie de la caisse de la voiture qui se trouve au voisinage du système d'accès nécessite un aménagement particulier. Notamment, la partie de la caisse se situant sous le caisson doit être dégagée, de sorte que la rotation du caisson vers le bas soit possible. L'installation du système d'accès sur une voiture préexistante est alors complexe et coûteuse, voire irréalisable.Indeed, the box is particularly bulky. Thus, for its rotation can be authorized, the part of the body of the car that is in the vicinity of the access system requires special development. In particular, the part of the box located under the box must be clear, so that the rotation of the box down is possible. The installation of the access system on a pre-existing car is then complex and expensive, or even unfeasible.

L'un des objets de l'invention est de proposer un système d'accès simple, peu coûteux et facile à installer.One of the objects of the invention is to provide a simple access system, inexpensive and easy to install.

A cet effet, l'invention concerne une voiture de véhicule ferroviaire du type précité, caractérisée en ce que le système d'accès comprend un seuil s'étendant à partir du plancher et monté rotatif par rapport au plancher autour d'un deuxième axe horizontal, le premier axe étant décalé dudit deuxième axe, le seuil reposant sur le châssis de sorte que la rotation du châssis autour du premier axe entraîne la rotation du seuil autour du deuxième axe.To this end, the invention relates to a rail vehicle car of the aforementioned type, characterized in that the access system comprises a threshold extending from the floor and rotatably mounted relative to the floor around a second horizontal axis , the first axis being offset from said second axis, the threshold resting on the frame so that the rotation of the frame about the first axis causes the rotation of the threshold around the second axis.

  • the Figure 1 is a schematic representation in perspective of an access system of a rail vehicle car according to the invention;

La Figure 1 illustre une voiture 2 de véhicule ferroviaire selon l'invention.The Figure 1 illustrates a car 2 of a railway vehicle according to the invention.

La voiture 2 comprend une caisse 4 formant la partie inférieure de la structure de la voiture 2 et sur laquelle est aménagé un plancher 6 pour la circulation des passagers dans la voiture 2. Le plancher 6 est sensiblement plan et horizontal et s'étend selon une direction longitudinale D de la voiture 2.The car 2 comprises a box 4 forming the lower part of the structure of the car 2 and on which is arranged a floor 6 for the circulation of the passengers in the car 2. The floor 6 is substantially flat and horizontal and extends according to a longitudinal direction D of the car 2.

La voiture 2 comprend également une porte d'accès 8 et un système d'accès 10 permettant aux passagers de monter et descendre de la voiture 2 par la porte d'accès 8, notamment pour rejoindre un quai 12 ferroviaire dont les bords sont hachurés sur la Figure 1.The car 2 also includes an access door 8 and an access system 10 allowing the passengers to get on and off the car 2 through the access door 8, in particular to reach a railway platform 12 whose edges are hatched on the Figure 1 .

De manière connue, les quais 12 ne présentent pas tous la même hauteur, et l'espacement entre les rails et le quai 12 est également différent d'un quai 12 à un autre. En outre, pour certains quais 12, l'espacement du quai aux rails et la hauteur de quai sont variables d'une portion du quai à l'autre. Les lacunes horizontale 14 et verticale 16 (Figure 2) entre le quai 12 et la voiture 2, qui correspondent à l'espacement horizontal, respectivement vertical entre le quai 12 et la voiture 2 sont donc variables.In a known manner, the platforms 12 do not all have the same height, and the spacing between the rails and the platform 12 is also different from one platform 12 to another. In addition, for certain platforms 12, the spacing of the platform to the rails and the platform height are variable from one portion of the platform to the other. The horizontal 14 and vertical 16 gaps ( Figure 2 ) between the platform 12 and the car 2, which correspond to the horizontal spacing, respectively vertical between the platform 12 and the car 2 are variable.

Le système d'accès 10 est agencé sur l'un des bords de la voiture 2 entre le plancher 6 et l'encadrement de la porte d'accès 8 et est adapté pour combler les lacunes horizontale 14 et verticale 16 entre le quai 12 et la voiture 2, et ce pour un grand nombre de quais 12.The access system 10 is arranged on one of the edges of the car 2 between the floor 6 and the frame of the access door 8 and is adapted to fill the horizontal gaps 14 and vertical 16 between the platform 12 and the car 2, and this for a large number of platforms 12.

A cet effet, le système d'accès 10 comprend un seuil 17 et un châssis 18 monté rotatif par rapport à la caisse 4 autour d'un premier axe X.For this purpose, the access system 10 comprises a threshold 17 and a frame 18 rotatably mounted relative to the body 4 about a first axis X.

Le seuil 17 forme une rampe d'accès inclinable pour la circulation des passagers entre le bord de la voiture 2 et le plancher 6.The threshold 17 forms a tilting ramp for passenger traffic between the edge of the car 2 and the floor 6.

Le seuil 17 se présente sous la forme d'une planche rigide, rectangulaire et sensiblement plane. Le seuil 17 est monté rotatif par rapport au plancher 6 autour d'un deuxième axe Y au niveau de l'un de ses bords. Le deuxième axe Y est parallèle à la direction longitudinale D et au premier axe X. Le seuil 17 est déplaçable en rotation entre une position haute dans laquelle le seuil 17 forme une pente inférieure ou égale à -8% avec le plan horizontal passant par le deuxième axe Y, et une position basse dans laquelle le seuil 17 forme une pente supérieure ou égale à +8% avec le plan horizontal passant par le deuxième axe Y.The threshold 17 is in the form of a rigid board, rectangular and substantially flat. The threshold 17 is rotatably mounted relative to the floor 6 around a second axis Y at one of its edges. The second axis Y is parallel to the longitudinal direction D and the first axis X. The threshold 17 is displaceable in rotation between a high position in which the threshold 17 forms a slope less than or equal to -8% with the horizontal plane passing through the second axis Y, and a low position in which the threshold 17 forms a slope greater than or equal to + 8% with the horizontal plane passing through the second axis Y.

Le seuil 17 présente une dimension selon la direction longitudinale D qui est sensiblement égale à la largeur de l'encadrement de la porte d'accès 8. En outre, le seuil 17 s'étend sensiblement depuis le plancher 6 jusqu'au bord de la voiture 2. Le seuil 17 est en appui sur le châssis 18 au niveau de son bord libre opposé au deuxième axe de rotation Y, de sorte que la rotation du châssis 18 autour du premier axe X entraîne la rotation du seuil 17 autour du deuxième axe Y.The threshold 17 has a dimension along the longitudinal direction D which is substantially equal to the width of the frame of the access door 8. In addition, the threshold 17 extends substantially from the floor 6 to the edge of the 2. The threshold 17 is supported on the frame 18 at its free edge opposite the second axis of rotation Y, so that the rotation of the frame 18 about the first axis X causes the rotation of the threshold 17 around the second axis Y.

Le seuil 17 repose sur le châssis 18 par l'intermédiaire d'une liaison autorisant une translation libre du seuil 17 par rapport au châssis 18 selon au moins une direction perpendiculaire au deuxième axe Y. Ceci est décrit plus en détail dans ce qui suit.The threshold 17 rests on the chassis 18 via a link allowing a free translation of the threshold 17 relative to the frame 18 in at least one direction perpendicular to the second axis Y. This is described in more detail in the following.

Le châssis 18 présente une forme générale parallélépipédique. Le châssis 18 comprend ainsi une face supérieure s'étendant sensiblement selon un plan P, une face inférieure, et quatre faces latérales dont deux faces orthogonales à la direction longitudinale D quelle que soit la position du châssis 18.The frame 18 has a generally parallelepipedal shape. The frame 18 thus comprises an upper face extending substantially in a plane P, a lower face, and four lateral faces, two faces orthogonal to the longitudinal direction D regardless of the position of the frame 18.

Le châssis 18 est monté rotatif entre :

  • une position haute correspondant à la position haute du seuil 17 et dans laquelle l'extrémité de la face supérieure du châssis 18 orientée vers le quai 12 est pivotée vers le haut par rapport au plan horizontal passant par le premier axe X, et
  • une position basse correspondant à la position basse du seuil 17 et dans laquelle l'extrémité de la face supérieure du châssis 18 orientée vers le quai 12 est pivotée vers le fond de la caisse 4 par rapport au plan horizontal passant par le premier axe X.
The frame 18 is rotatably mounted between:
  • a high position corresponding to the high position of the threshold 17 and in which the end of the upper face of the frame 18 facing the platform 12 is pivoted upwards with respect to the horizontal plane passing through the first axis X, and
  • a low position corresponding to the low position of the threshold 17 and wherein the end of the upper face of the frame 18 facing the platform 12 is pivoted towards the bottom of the body 4 relative to the horizontal plane passing through the first axis X.

Dans l'exemple de la Figure 1, le châssis 18 se trouve dans une position de repos dans laquelle le plan P est sensiblement parallèle au plancher 6. Dans la position de repos du châssis 18, le seuil 17 est légèrement incliné par rapport au plancher 6.In the example of the Figure 1 , the frame 18 is in a rest position in which the plane P is substantially parallel to the floor 6. In the rest position of the frame 18, the threshold 17 is slightly inclined with respect to the floor 6.

L'axe X est sensiblement horizontal, c'est-à-dire que l'axe X est sensiblement parallèle à la direction longitudinale D de la voiture 2. L'axe X est décalé verticalement par rapport au plancher 6 en direction du fond de la caisse 4 de la voiture 2. En outre, le premier axe X est décalé du deuxième axe Y en direction du bord de la voiture 2 sur lequel le système d'accès 10 se trouve. Le premier axe X et le deuxième axe Y ont une position relative telle que la position haute du châssis 18 corresponde à la position haute du seuil 17, et telle que la position basse du châssis 18 corresponde à la position basse du seuil 17.The X axis is substantially horizontal, that is to say the X axis is substantially parallel to the longitudinal direction D of the car 2. The X axis is vertically offset from the floor 6 towards the bottom of the car. the body 4 of the car 2. In addition, the first axis X is offset from the second axis Y towards the edge of the car 2 on which the access system 10 is located. The first axis X and the second axis Y have a relative position such that the high position of the frame 18 corresponds to the high position of the threshold 17, and such that the low position of the frame 18 corresponds to the low position of the threshold 17.

En outre, le premier axe X est décalé latéralement du centre de gravité du châssis 18 en direction du bord opposé de la voiture 2, de sorte que l'extrémité du châssis 18 qui est dirigée vers le quai 12 tend à pivoter vers le fond de la caisse 4 sous l'effet du poids du châssis 18.In addition, the first axis X is shifted laterally from the center of gravity of the frame 18 towards the opposite edge of the car 2, so that the end of the frame 18 which is directed towards the platform 12 tends to pivot towards the bottom of the body 4 under the effect of the weight of the frame 18.

Le châssis 18 comprend des patins de support 20 sur lesquels le seuil 17 repose et sur lesquels le seuil 17 glisse lorsque le châssis 18 pivote. Ceci est décrit plus en détail dans ce qui suit.The frame 18 comprises support pads 20 on which the threshold 17 rests and on which the threshold 17 slides when the frame 18 pivots. This is described in more detail in the following.

Dans l'exemple des Figures, le châssis 18 comprend trois patins de support 20. Les patins de support 20 sont situés sur la face supérieure du châssis et à proximité de son bord orienté en direction du quai 12. Chaque patin de support 20 se présente sous la forme d'une portion d'anneau ou de disque et est en saillie par rapport à la face supérieure du châssis 18. Via les patins de support 20, le seuil 17 repose sur le châssis 18 par l'intermédiaire d'une liaison linéaire rectiligne.In the example of the figures, the frame 18 comprises three support pads 20. The support pads 20 are located on the upper face of the frame and near its edge oriented towards the platform 12. Each support pad 20 presents itself in the form of a ring or disc portion and protrudes from the upper face of the frame 18. Via the support pads 20, the threshold 17 rests on the frame 18 via a link rectilinear linear.

Le système d'accès 10 comprend également deux mécanismes de rotation 22 pour la mise en rotation du châssis 18 autour du premier axe X. Les deux mécanismes de rotation 22 sont identiques l'un à l'autre et sont situés sur les faces latérales opposées du châssis 18 en regard l'un de l'autre et qui sont orthogonales au premier axe de rotation X.The access system 10 also comprises two rotation mechanisms 22 for rotating the chassis 18 around the first axis X. The two rotation mechanisms 22 are identical to each other and are located on the opposite lateral faces. of the frame 18 facing one another and which are orthogonal to the first axis of rotation X.

Chaque mécanisme de rotation 22 comprend un organe de commande 24 déplaçable, un mécanisme de conversion 26 pour la conversion du mouvement de l'organe de commande 24 en mouvement de rotation du châssis 18, et un actionneur 28 de l'organe de commande 24.Each rotation mechanism 22 comprises a displaceable control member 24, a conversion mechanism 26 for converting the movement of the control member 24 into a rotational movement of the frame 18, and an actuator 28 of the control member 24.

En référence à la Figure 2, l'organe de commande 24 comprend une glissière 30 solidaire de la face latérale du châssis 18 et s'étendant selon une direction de coulissement C associée sensiblement parallèle au plan P. En outre, l'organe de commande 24 comprend un chariot 32 monté coulissant dans la glissière 30.With reference to the Figure 2 , the control member 24 comprises a slideway 30 integral with the lateral face of the frame 18 and extending in a sliding direction C associated substantially parallel to the plane P. In addition, the control member 24 comprises a carriage 32 mounted sliding in the slideway 30.

Le chariot 32 comprend un galet de guidage 34 engagé dans la glissière 30 et assurant à la fois le guidage du chariot 32 le long de la glissière 30 et son maintien dans la glissière 30. Le chariot 32 comprend également un galet d'appui 35 au contact du mécanisme de conversion 26.The carriage 32 comprises a guide roller 34 engaged in the slide 30 and ensuring both the guiding of the carriage 32 along the slideway 30 and its retention in the slide 30. The carriage 32 also comprises a support roller 35 at contact of the conversion mechanism 26.

Le mécanisme de conversion 26 comprend une surface de guidage 36. La surface de guidage 36 est solidaire de la caisse 4 de la voiture 2.The conversion mechanism 26 comprises a guide surface 36. The guide surface 36 is integral with the body 4 of the car 2.

La surface de guidage 36 est au contact du galet d'appui 35. Plus spécifiquement, le galet d'appui 35 est en appui sur la surface de guidage 36 et est déplaçable le long de la surface de guidage 36. Le galet d'appui 35 est maintenu plaqué contre la surface de guidage 36 sous l'effet du poids du châssis 18.The guide surface 36 is in contact with the support roller 35. More specifically, the support roller 35 bears on the guide surface 36 and is displaceable along the guide surface 36. The support roller 35 is held pressed against the guide surface 36 under the effect of the weight of the frame 18.

La surface de guidage 36 comprend trois portions de guidage 38, 40, 42 rectilignes consécutives. La surface de guidage 36 forme ainsi un trajet de guidage du galet d'appui 35 qui est continu.The guide surface 36 comprises three straight guide portions 38, 40, 42. The guide surface 36 thus forms a guide path of the support roller 35 which is continuous.

Plus spécifiquement, la surface de guidage 36 comprend :

  • une première portion de guidage 38 s'étendant sensiblement parallèlement au plancher 6 ;
  • une deuxième portion de guidage 40 inclinée par rapport à la première portion de guidage 38; et
  • une troisième portion de guidage 42 inclinée par rapport à la première portion de guidage 38.
More specifically, the guiding surface 36 comprises:
  • a first guide portion 38 extending substantially parallel to the floor 6;
  • a second guide portion 40 inclined relative to the first guide portion 38; and
  • a third guide portion 42 inclined relative to the first guide portion 38.

Les deuxième et troisième portions de guidage 40, 42 sont situées de part et d'autre de la première portion de guidage 38.The second and third guide portions 40, 42 are located on either side of the first guide portion 38.

Comme on le verra par la suite, la rotation du châssis 18 est induite par le déplacement du chariot 32 et du galet d'appui 35 le long des portions de guidage 38, 40, 42. Les deuxième et troisième portions de guidage 40, 42 sont respectivement associées à un sens de rotation donné du châssis 18. Le sens de rotation du châssis 18 correspondant est fonction de l'inclinaison des portions de guidage 40, 42, qui est la même pour les deux portions de guidage 40, 42.As will be seen later, the rotation of the frame 18 is induced by the displacement of the carriage 32 and the support roller 35 along the guide portions 38, 40, 42. The second and third guide portions 40, 42 are respectively associated with a given direction of rotation of the frame 18. The direction of rotation of the corresponding frame 18 is a function of the inclination of the guide portions 40, 42, which is the same for the two guide portions 40, 42.

Dans l'exemple illustré, les deuxième et troisième portions de guidage 38, 40 sont inclinées de façon à former une pente positive par rapport au plancher 6. La deuxième portion de guidage 40 est associée au sens de rotation de châssis 18 dans lequel le bord du châssis 18 orienté vers le quai 12 pivote vers le fond de la caisse 4, et la troisième portion de guidage 42 est associée à l'autre sens de rotation du châssis 18.In the illustrated example, the second and third guide portions 38, 40 are inclined so as to form a positive slope relative to the floor 6. The second guide portion 40 is associated with the direction of frame rotation 18 in which the edge of the frame 18 facing the platform 12 pivots towards the bottom of the body 4, and the third guide portion 42 is associated with the other direction of rotation of the frame 18.

En variante, les deuxième et troisième portions de guidage 40, 42 sont inclinées de façon à former une pente négative par rapport au plancher 6. En pratique, l'inclinaison des deuxième et troisième portions de guidage 40, 42 est choisie en fonction des caractéristiques de l'actionneur 28.In a variant, the second and third guide portions 40, 42 are inclined so as to form a negative slope with respect to the floor 6. In practice, the inclination of the second and third guide portions 40, 42 is chosen according to the characteristics of the actuator 28.

L'actionneur 28 est solidaire du châssis 18 et est propre à mettre en mouvement l'organe de commande 24.The actuator 28 is integral with the frame 18 and is able to set the control member 24 in motion.

Dans l'exemple illustré, l'actionneur 28 est un actionneur linéaire s'étendant sensiblement selon la direction de coulissement C. Plus spécifiquement, l'actionneur 28 est un vérin comprenant un piston et une tige dont une extrémité est fixée au chariot 32 et dont l'autre extrémité est engagée dans le piston.In the illustrated example, the actuator 28 is a linear actuator extending substantially in the direction of sliding C. More specifically, the actuator 28 is a jack comprising a piston and a rod whose end is fixed to the carriage 32 and whose other end is engaged in the piston.

En outre, le système d'accès 10 comprend un marchepied 44 monté coulissant dans le châssis 18 et un nez d'appui 45.In addition, the access system 10 comprises a step 44 slidably mounted in the frame 18 and a support nose 45.

Le marchepied 44 est adapté pour combler les lacunes horizontale 14 et verticale 16 entre la voiture 2 et le quai 12.The step 44 is adapted to fill the horizontal gaps 14 and vertical 16 between the car 2 and the platform 12.

Le marchepied 44 comprend une palette 46 sensiblement plane et montée coulissante dans le châssis 18 selon une direction parallèle au plan P du châssis 18. La palette 46 est montée coulissante entre une position déployée dans laquelle tout ou partie de la palette 46 forme une rampe d'accès s'étendant entre le bord de la voiture 2 et le quai 12, et une position rétractée dans laquelle la palette 46 est rétractée dans le châssis 18 et le marchepied 44 ne fait pas saillie en dehors de la voiture 2.The step 44 comprises a pallet 46 substantially flat and slidably mounted in the frame 18 in a direction parallel to the plane P of the frame 18. pallet 46 is slidably mounted between an extended position in which all or part of the pallet 46 forms an access ramp extending between the edge of the car 2 and the platform 12, and a retracted position in which the pallet 46 is retracted in the frame 18 and the step 44 does not protrude outside the car 2.

Le nez d'appui 45 est adapté pour venir au contact du quai 12 en position déployée du marchepied 44. Le nez d'appui 45 est situé à l'extrémité de la palette 46 et est venu de matière avec la palette 46. Le nez d'appui 45 présente une forme recourbée vers le bas.The support nose 45 is adapted to come into contact with the platform 12 in the deployed position of the step 44. The support nose 45 is located at the end of the pallet 46 and is integral with the pallet 46. The nose support 45 has a curved shape downwards.

Le système d'accès 10 comprend en outre un système de détection et commande 48 configuré pour évaluer les lacunes horizontale 14 et verticale 16 et pour commander le déploiement du marchepied 44 et l'actionnement des mécanismes de rotation 22 en fonction des lacunes horizontale 14 et verticale 16 détectées. Plus spécifiquement, le système de détection et commande 48 est configuré pour commander les mécanismes de rotation 22 et le marchepied 44 de sorte que l'espacement entre l'arête du quai 12 et le bord de la palette 46 du marchepied 44 soit inférieur ou égal à 15 mm, et de préférence sensiblement nul.The access system 10 further comprises a detection and control system 48 configured to evaluate the horizontal and vertical gaps 14 and to control the deployment of the step 44 and the actuation of the rotation mechanisms 22 as a function of the horizontal gaps 14 and vertical 16 detected. More specifically, the detection and control system 48 is configured to control the rotation mechanisms 22 and the step 44 so that the spacing between the edge of the platform 12 and the edge of the pallet 46 of the step 44 is less than or equal to at 15 mm, and preferably substantially zero.

Le fonctionnement du système d'accès 10 va maintenant être décrit en référence aux Figures 1 à 3.The operation of the access system 10 will now be described with reference to Figures 1 to 3 .

Lorsque la voiture 2 est en circulation sur une voie, la porte d'accès 8 est fermée, le marchepied 44 est en position rétractée, le châssis 18 se trouve dans sa position de repos et le seuil 17 est en appui sur le châssis 18. Le galet d'appui 35 des chariots 32 des mécanismes de rotation 22 se trouve en appui sur la première portion 38 de la surface de guidage 36 correspondante.When the car 2 is in circulation on a track, the access door 8 is closed, the step 44 is in the retracted position, the chassis 18 is in its rest position and the threshold 17 bears on the chassis 18. The support roller 35 of the carriages 32 of the rotation mechanisms 22 is supported on the first portion 38 of the corresponding guide surface 36.

Lorsque la voiture 2 se trouve en gare et que la porte d'accès 8 est ouverte ou que son ouverture est commandée, le système de détection et commande 48 détecte la lacune horizontale 14 et la lacune verticale 16.When the car 2 is at the station and the access door 8 is open or its opening is controlled, the detection and control system 48 detects the horizontal gap 14 and the vertical gap 16.

En fonction des lacunes 14, 16 détectées, le système de détection et commande 48 commande les mécanismes de rotation 22 simultanément de façon à adapter l'inclinaison du seuil 17 à la lacune verticale 16.Depending on the gaps 14, 16 detected, the detection and control system 48 controls the rotation mechanisms 22 simultaneously so as to adapt the inclination of the threshold 17 to the vertical gap 16.

Plus spécifiquement, pour chaque mécanisme de rotation 22, le système de détection et commande 48 commande l'actionneur 28 linéaire de façon à mettre en mouvement l'organe de commande 24, ce qui, via le mécanisme de conversion 26 associé, met en rotation le châssis 18 autour du premier axe X et modifie l'inclinaison du seuil 17.More specifically, for each rotation mechanism 22, the detection and control system 48 controls the linear actuator 28 to move the control member 24, which, via the associated conversion mechanism 26, rotates the frame 18 around the first axis X and modifies the inclination of the threshold 17.

En référence aux Figures 1 à 3, le système de détection et commande 48 commande le déplacement de la tige dans le piston du vérin de l'actionneur 28, ce qui se traduit par le déplacement du chariot 32 dans la glissière 30 associée via le galet de guidage 34. En se déplaçant, le chariot 32 entraîne en déplacement le galet d'appui 35 le long de la surface de guidage 36.With reference to Figures 1 to 3 , the detection and control system 48 controls the displacement of the rod in the piston of the jack of the actuator 28, which is translated by the displacement of the carriage 32 in the associated slideway 30 via the guide roller 34. In moving, the carriage 32 drives the support roller 35 along the guiding surface 36 in displacement.

En fonction de l'inclinaison du seuil 17 souhaitée, le galet d'appui 35 est déplacé le long de l'une ou l'autre des deuxième et troisième portions de guidage 40, 42.Depending on the inclination of the desired threshold 17, the support roller 35 is moved along one or the other of the second and third guide portions 40, 42.

Dans l'exemple illustré, pour abaisser le seuil 17, c'est-à-dire pour augmenter la pente qu'il forme avec le plancher 6, le galet d'appui 35 est déplacé en direction de la deuxième portion de guidage 40. Du fait de l'inclinaison de la deuxième portion de guidage 40 par rapport à l'horizontale, le déplacement du galet d'appui 35 se traduit par un pivotement du châssis 18 autour du premier axe X vers le fond de la caisse 4 sous l'effet du poids du châssis 18.In the example shown, to lower the threshold 17, that is to say to increase the slope it forms with the floor 6, the support roller 35 is moved towards the second guide portion 40. Due to the inclination of the second guide portion 40 relative to the horizontal, the displacement of the support roller 35 results in a pivoting of the frame 18 around the first axis X towards the bottom of the body 4 under the effect of chassis weight 18.

La rotation du châssis 18 autour du premier axe X entraîne le déplacement des patins de support 20 et de la liaison du châssis 18 au seuil 17 vers le fond de la caisse 4. Le seuil 17 pivote ainsi autour du deuxième axe Y, son bord opposé au plancher 6 pivotant vers le fond de la caisse 4, et glisse sur les patins de support 20 du fait du décalage du premier axe X par rapport au deuxième axe Y.The rotation of the frame 18 around the first axis X causes the displacement of the support pads 20 and the connection of the frame 18 to the threshold 17 towards the bottom of the box 4. The threshold 17 thus pivots about the second axis Y, its opposite edge the floor 6 pivoting towards the bottom of the body 4, and slides on the support pads 20 due to the shift of the first axis X relative to the second axis Y.

A l'inverse, pour élever le seuil 17, c'est-à-dire pour diminuer la pente qu'il forme avec le plancher 6, le galet d'appui 35 est déplacé le long de la troisième portion de guidage 42.Conversely, to raise the threshold 17, that is to say to reduce the slope that it forms with the floor 6, the support roller 35 is displaced along the third guide portion 42.

La commande simultanée des deux mécanismes de rotation 22 permet de répartir les efforts entre les deux mécanismes 22, ainsi que de compenser le couple appliqué au châssis 18 par l'actionneur 28 de chaque mécanisme de rotation 22 et tendant à faire tourner le châssis autour d'un axe vertical, ce qui se traduirait par des efforts nuisibles appliqués à chacun des chariots 32 si seul l'un des mécanismes de rotation 22 était présent.Simultaneous control of the two rotation mechanisms 22 distributes the forces between the two mechanisms 22, as well as compensating the torque applied to the frame 18 by the actuator 28 of each rotation mechanism 22 and tending to rotate the frame around a vertical axis, which would result in harmful efforts applied to each of the carriages 32 if only one of the rotation mechanisms 22 was present.

Parallèlement et/ou préalablement à la commande de la rotation du châssis 18, le système de détection et commande 48 commande le déploiement du marchepied 44 par rapport au châssis 18 sur une longueur de course telle que, lorsque le châssis 18 est pivoté, le nez d'appui 45 vienne au contact du quai 12 à proximité de son arête.In parallel and / or prior to the control of the rotation of the frame 18, the detection and control system 48 controls the deployment of the step 44 with respect to the frame 18 over a running length such that, when the frame 18 is pivoted, the nose 45 comes into contact with the dock 12 near its edge.

Dans cette configuration, les rampes d'accès respectivement formées par la palette 46 du marchepied 44 et le seuil 17 sont sensiblement dans la continuité l'une de l'autre, et les lacunes horizontale 14 et verticale 16 sont comblées par le marchepied 44.In this configuration, the ramps respectively formed by the pallet 46 of the step 44 and the threshold 17 are substantially in continuity with one another, and the horizontal and vertical gaps 14 and 14 are filled by the step 44.

En outre, le bord du seuil 17 opposé au deuxième axe Y et la palette 46 sont à une distance l'un de l'autre inférieure ou égale à 15 mm, et de préférence sont au plus proche l'un de l'autre. Ceci permet de limiter le ressaut pour passer de la palette 46 du marchepied 44 au seuil 17, et donc de rendre ce passage réalisable par les personnes à mobilité réduite ou les usagers en fauteuil roulant (souvent désignés par l'acronyme UFR) et ce sans assistance extérieure.In addition, the edge of the threshold 17 opposite the second axis Y and the pallet 46 are at a distance from each other less than or equal to 15 mm, and preferably are closer to one another. This makes it possible to limit the projection to move from the pallet 46 of the step 44 to the threshold 17, and thus to make this passage achievable by the persons to reduced mobility or wheelchair users (often referred to by the acronym UFR) without external assistance.

Par ailleurs, le bord de la palette 46 du marchepied 44 et l'arête du quai 12 sont situés à une distance l'un de l'autre inférieure ou égale à 20 mm, et de préférence sont au plus proche l'un de l'autre. Ceci permet de limiter le ressaut pour passer du quai 12 à la palette 44, et donc de rendre ce passage réalisable pour des personnes à mobilité réduite ou les usagers en fauteuil roulant et ce sans assistance extérieure. En outre, le seuil 17 est adapté pour former une pente comprise entre -8% et +8%. Ces valeurs sont prescrites et correspondent aux valeurs limites des pentes que les personnes à mobilité réduite ou les usagers en fauteuil roulant peuvent franchir sans assistance extérieure..Furthermore, the edge of the pallet 46 of the step 44 and the edge of the platform 12 are located at a distance from each other less than or equal to 20 mm, and preferably are at the closest one of the 'other. This makes it possible to limit the projection to go from the platform 12 to the pallet 44, and thus to make this passage feasible for persons with reduced mobility or wheelchair users and without outside assistance. In addition, the threshold 17 is adapted to form a slope of between -8% and + 8%. These values are prescribed and correspond to the limit values for slopes which people with reduced mobility or wheelchair users can cross without outside assistance.

En vue du départ du véhicule ferroviaire, la palette 46 du marchepied 44 est rétractée dans le châssis 18 et le châssis 18 est pivoté par les mécanismes de rotation 22 jusqu'à sa position de repos, ce qui ramène le seuil 17 dans sa position initiale.For the departure of the railway vehicle, the pallet 46 of the step 44 is retracted into the frame 18 and the frame 18 is pivoted by the rotation mechanisms 22 to its rest position, which brings the threshold 17 back to its initial position. .

Dans une voiture 2 selon l'invention, l'association du seuil 17 du châssis 18 et la mise en rotation du seuil 17 autour du deuxième axe Y par la mise en rotation du châssis 18 autour du premier axe X permettent de diminuer le débattement du système d'accès 10 lors de son fonctionnement, et donc l'aménagement de la caisse 4 requis pour le fonctionnement du système d'accès 10. Le système d'accès 10 est donc plus aisé à installer sur des voitures existantes, et peut être installé sur des voitures sur lesquelles les systèmes connus ne peuvent pas être installés.In a car 2 according to the invention, the combination of the threshold 17 of the frame 18 and the setting in rotation of the threshold 17 around the second axis Y by the rotation of the frame 18 around the first axis X make it possible to reduce the deflection of the access system 10 during its operation, and therefore the development of the box 4 required for the operation of the access system 10. The access system 10 is easier to install on existing cars, and can be installed on cars where known systems can not be installed.

Par ailleurs, la rampe d'accès formée par le marchepied 44 et le seuil 17 est aisée à franchir pour les personnes à mobilité réduite ou les UFR (Usagers en fauteuil roulant) sans assistance extérieure., et ce pour un grand nombre de quais.In addition, the access ramp formed by the step 44 and the threshold 17 is easy to cross for people with reduced mobility or UFR (wheelchair users) without outside assistance, and this for a large number of platforms.

En outre, les mécanismes de rotation 22 sont de conception simple et fiable du fait de l'utilisation d'un mécanisme de conversion 26 convertissant le mouvement de coulissement du chariot 32 en un mouvement de rotation du châssis 18.In addition, the rotation mechanisms 22 are of simple and reliable design because of the use of a conversion mechanism 26 converting the sliding movement of the carriage 32 into a rotational movement of the frame 18.

Par ailleurs, la disposition de la première portion de guidage 38 a pour effet que dans la position de repos du châssis 18, l'effort appliqué à l'actionneur 28 par le poids du châssis 18 est moindre.Furthermore, the provision of the first guide portion 38 has the effect that in the rest position of the frame 18, the force applied to the actuator 28 by the weight of the frame 18 is less.

En variante, le premier axe X et le deuxième axe Y sont décalés verticalement l'un de l'autre de sorte qu'en position de repos du châssis 18, le seuil 17 s'étende sensiblement horizontalement. Ceci permet de minimiser la rotation du châssis 18 à effectuer pour déplacer le seuil 17 jusqu'à sa position haute ou sa position basse, et ainsi à limiter encore l'aménagement de la caisse 4 au niveau du système d'accès 10.Alternatively, the first axis X and the second axis Y are offset vertically from each other so that in the rest position of the frame 18, the threshold 17 extends substantially horizontally. This makes it possible to minimize the rotation of the frame 18 to be made to move the threshold 17 to its high position or its low position, and thus to further limit the arrangement of the box 4 at the level of the access system 10.

En variante, la surface de guidage 36 des mécanismes de rotation 22 ne comprend pas de première portion de guidage 38. Les deuxième et troisième portions de guidage 40, 42 sont successives.In a variant, the guide surface 36 of the rotation mechanisms 22 does not comprise a first guide portion 38. The second and third guide portions 40, 42 are successive.

Ceci permet de minimiser la course du chariot 32 nécessaire pour opérer la rotation du châssis 18 depuis sa position de repos, et donc de minimiser les dimensions de l'actionneur 28. En outre, dans cette variante, l'effort repris par l'actionneur 28 en position du repos du châssis 18 et dû au poids du châssis 18 est limité du fait qu'il est projeté sur la surface de guidage 36, qui est inclinée par rapport à la verticale.This makes it possible to minimize the stroke of the carriage 32 necessary to operate the rotation of the frame 18 from its rest position, and therefore to minimize the dimensions of the actuator 28. In addition, in this variant, the force taken up by the actuator 28 in the rest position of the frame 18 and due to the weight of the frame 18 is limited because it is projected on the guide surface 36, which is inclined relative to the vertical.

En variante, la surface de guidage 36 est solidaire du châssis 18. En outre, l'actionneur 28 et l'organe de commande 24, c'est-à-dire le chariot 32 munis des galets 34, 35, sont solidaires de la caisse 4. Plus spécifiquement, la glissière 30 et le vérin de l'actionneur 28 s'étendent sensiblement horizontalement. En outre, le galet d'appui 35 est situé sous la surface de guidage 36 et reprend le poids du châssis. Cette variante constitue une alternative de réalisation d'un système d'accès 10 d'une voiture 2 selon l'invention.In a variant, the guide surface 36 is integral with the frame 18. In addition, the actuator 28 and the control member 24, that is to say the carriage 32 provided with the rollers 34, 35, are integral with the 4. More specifically, the slide 30 and the cylinder of the actuator 28 extend substantially horizontally. In addition, the support roller 35 is located under the guiding surface 36 and takes the weight of the frame. This variant constitutes an alternative embodiment of an access system 10 of a car 2 according to the invention.

En variante, en référence à la Figure 2, le seuil 17 comprend une rampe 50 inclinée (en pointillés sur la Figure 2) située à son extrémité libre opposée au plancher 6. La rampe 50 s'étend sensiblement sur toute la largeur du seuil 17 et est adaptée pour faciliter le franchissement du saut formé entre le seuil 17 et la palette 44 et qui est notamment dû à l'épaisseur du seuil 17. Dans certains modes de réalisation de cette variante, la planche formant le seuil 17 est légèrement raccourcie de sorte que la rampe 50 se trouve intégralement dans la voiture 2 lorsque la porte d'accès 8 est fermée.Alternatively, with reference to the Figure 2 , the threshold 17 comprises an inclined ramp 50 (dashed on the Figure 2 ) at its free end opposite the floor 6. The ramp 50 extends substantially over the entire width of the threshold 17 and is adapted to facilitate the crossing of the jump formed between the threshold 17 and the pallet 44 and which is particularly due to the Threshold thickness 17. In some embodiments of this variant, the board forming the threshold 17 is slightly shortened so that the ramp 50 is fully in the car 2 when the access door 8 is closed.

En variante, en référence à la Figure 3, le châssis 18 comprend un bossage de support 52 en remplacement des patins de support 20. De la même manière que les patins de support 20, le bossage 52 est situé au niveau de l'extrémité de la face supérieure du châssis 18 qui est orientée en direction du quai 12. Le bossage 52 s'étend sur tout ou partie de la largeur du châssis 18. Le seuil 17 repose sur le bossage 52 au niveau d'une ligne de contact, de sorte que le châssis 18 et le seuil 17 sont liés par une liaison linéaire rectiligne de la même manière que précédemment.Alternatively, with reference to the Figure 3 , the frame 18 comprises a support boss 52 replacing the support pads 20. In the same way as the support pads 20, the boss 52 is located at the end of the upper face of the frame 18 which is oriented towards the platform 12. The boss 52 extends over all or part of the width of the frame 18. The threshold 17 rests on the boss 52 at a nip, so that the frame 18 and the threshold 17 are linked by a straight linear connection in the same manner as before.

De manière générale, le seuil 17 est en appui verticalement sur le châssis 18 tout en pouvant glisser par rapport au châssis 18 pour compenser le mouvement relatif du seuil 17 et du châssis 18 dû au décalage du premier axe X et du deuxième axe Y.In general, the threshold 17 bears vertically on the frame 18 while being able to slide relative to the frame 18 to compensate for the relative movement of the threshold 17 and the frame 18 due to the offset of the first axis X and the second axis Y.

En variante, la surface de guidage 36 est montée sur le chariot 32 de l'organe de commande 24. L'organe de commande 24 est monté coulissant sur le châssis 18.In a variant, the guide surface 36 is mounted on the carriage 32 of the control member 24. The control member 24 is slidably mounted on the frame 18.

Dans cette variante, le galet d'appui 35 n'est pas porté par le chariot 32. Le galet d'appui 35 est solidaire de la caisse 4. La surface de guidage 36 portée par le chariot 32 est en appui sur le galet d'appui 35, de telle manière que le coulissement du chariot 32 entraîne la rotation du châssis 18.In this variant, the support roller 35 is not carried by the carriage 32. The support roller 35 is integral with the body 4. The guide surface 36 carried by the carriage 32 is supported on the support roller 35, so that the sliding of the carriage 32 causes the chassis 18 to rotate.

Dans cette variante, le déplacement du chariot 32 le long de la glissière 30 induit le déplacement de la surface de guidage 36 relativement au galet d'appui 35, à l'inverse du mode de réalisation principal décrit précédemment dans lequel le chariot 32 déplace le galet d'appui 35 relativement à la surface de guidage 36.In this variant, the displacement of the carriage 32 along the slide 30 induces the displacement of the guide surface 36 relative to the support roller 35, unlike the main embodiment previously described in which the carriage 32 moves the bearing roller 35 relative to the guide surface 36.

En variante encore, le premier axe X et le deuxième axe Y sont disposés de telle que sorte que le seuil 17 soit en position haute ou en position basse lorsque le châssis 18 est en position de repos. Ceci permet de supprimer la portion de guidage 38, 40, 42 de la surface de guidage 36 correspondant au sens de rotation du châssis 18 qui n'est plus requis pour le fonctionnement du système d'accès 10. Comme précédemment, ceci permet de minimiser l'encombrement des actionneurs 28.In another variant, the first axis X and the second axis Y are arranged such that the threshold 17 is in the up position or in the low position when the frame 18 is in the rest position. This makes it possible to eliminate the guide portion 38, 40, 42 of the guiding surface 36 corresponding to the direction of rotation of the frame 18 which is no longer required for the operation of the access system 10. As previously, this makes it possible to minimize the size of the actuators 28.

Dans d'autres modes de réalisation, les modes de réalisation décrits précédemment et techniquement compatibles entre eux sont combinés.In other embodiments, the embodiments previously described and technically compatible with each other are combined.
