Description

La présente invention concerne une voiture à deux étages pour véhicule ferroviaire, comprenant au moins une sortie d'évacuation d'urgence.The present invention relates to a two-stage car for a railway vehicle, comprising at least one emergency evacuation exit.

Généralement, dans une voiture à deux étages, l'évacuation d'urgence des passagers de l'étage supérieur est réalisée au travers d'une fenêtre de cet étage supérieur, qui doit préalablement être brisée au moyen d'un marteau prévu à cet effet. Une échelle de corde est ensuite suspendue pour permettre la descente des passagers.Generally, in a double-decker car, the emergency evacuation of passengers from the upper floor is carried out through a window in this upper floor, which must first be broken by means of a hammer provided for this purpose. . A rope ladder is then suspended to allow the passengers to descend.

Une telle évacuation est parfois difficile à mettre en oeuvre, puisque le bris de la fenêtre est une opération qui peut être complexe, qu'il existe un risque de blessure avec des débris de verre, que l'installation de l'échelle de corde peut être fastidieuse dans une situation d'urgence, et qu'il existe un risque de chute de passagers descendant par l'échelle de corde.Such an evacuation is sometimes difficult to implement, since the breaking of the window is an operation which can be complex, that there is a risk of injury with broken glass, that the installation of the rope ladder can be tedious in an emergency situation, and that there is a risk of falling passengers descending by the rope ladder.

L'invention a notamment pour but de remédier à ces inconvénients en fournissant une sortie d'évacuation d'urgence, pour l'évacuation de l'étage supérieur, plus simple et plus sécurisée.The invention particularly aims to remedy these drawbacks by providing an emergency evacuation outlet, for the evacuation of the upper floor, simpler and more secure.

A cet effet, l'invention a notamment pour objet une voiture à deux étages de véhicule ferroviaire, comprenant un étage supérieur et un étage inférieur séparés par un plancher intermédiaire, caractérisé en ce que :

  • le plancher intermédiaire comporte un cadre délimitant une ouverture de passage pour une personne,
  • l'ouverture de passage est obturée au moins en partie par une trappe amovible,
  • la trappe amovible comporte au moins un loquet mobile entre une position en saillie depuis un bord respectif de la trappe et une position escamotée, et un mécanisme de déplacement du loquet, le mécanisme de déplacement comprenant une serrure et une clé correspondant à la serrure, tel que l'actionnement de la clé dans la serrure entraîne le déplacement du loquet, et
  • le cadre comporte, pour chaque loquet mobile, une gâche complémentaire.
To this end, the subject of the invention is in particular a car with two stages of a railway vehicle, comprising an upper stage and a lower stage separated by an intermediate floor, characterized in that:
  • the intermediate floor includes a frame delimiting a passage opening for a person,
  • the passage opening is closed at least in part by a removable hatch,
  • the removable hatch comprises at least one movable latch between a projecting position from a respective edge of the hatch and a retracted position, and a latch movement mechanism, the movement mechanism comprising a lock and a key corresponding to the lock, such actuation of the key in the lock causes the latch to move, and
  • the frame includes, for each movable latch, a complementary strike.

Une telle trappe est simple à ouvrir et permet une évacuation vers le premier étage, moins périlleuse qu'une descente à travers une fenêtre de l'étage supérieur.Such a hatch is simple to open and allows evacuation to the first floor, less dangerous than a descent through a window of the upper floor.

La trappe est fermée au moyen d'un outil formant clé, cet outil étant généralement rangé dans un boitier à n'ouvrir qu'en cas d'urgence, si bien qu'il est peu probable qu'un passager ouvre cette trappe en dehors d'une situation d'urgence.The hatch is closed by means of a key-forming tool, this tool generally being stored in a case to be opened only in an emergency, so that a passenger is unlikely to open this hatch outside of an emergency.

Une voiture selon l'invention peut comporter l'une ou plusieurs des caractéristiques suivantes, prises seules ou selon toutes combinaisons techniquement envisageables.

  • La voiture comporte un outil de déverrouillage en forme de T, comprenant une branche principale s'étendant entre une extrémité libre formant la clé et une extrémité liée à deux branches de préhension.
  • Au moins une branche de préhension est reliée à la branche principale par une liaison pivot d'axe perpendiculaire à la branche principale et à cette branche de préhension.
  • L'étage inférieur est équipé de sièges comprenant chacun un dossier et une assise, l'ouverture de passage étant agencée au moins en partie au-dessus de l'assise d'au moins l'un des sièges.
  • L'étage inférieur est délimité transversalement par des parois munies de fenêtres, l'ouverture de passage étant agencée de sorte qu'un plan transversal passant par cette ouverture de passage passe également par l'une des fenêtres.
  • Les fenêtres d'au moins l'une des parois étant alignées entre deux fenêtres d'extrémités, l'ouverture de passage est agencée de sorte que ledit plan transversal passe par l'une des fenêtres d'extrémité.
  • Ledit plan transversal est un plan médian de l'ouverture de passage et également un plan médian de la fenêtre correspondante.
  • La trappe comporte au moins une poignée de préhension.

The invention also relates to a rail vehicle comprising at least one two-stage car as defined above, the at least one car comprising a first class zone and a second class zone, the first and second class zones comprising identical intermediate floors comprising identical passage openings, and in which:
  • in the first class area, a transverse part of the passage opening is covered by a first additional floor element,
  • in the second class area, two opposite transverse parts of the passage opening are covered by respective second additional floor elements,
  • the hatches in the first and second class areas have identical dimensions.

De manière optionnelle, le véhicule ferroviaire comprend, pour chaque élément de plancher additionnel, une traverse de support respective, connectée au cadre, et sur laquelle l'élément de plancher additionnel repose en partie, chaque plancher intermédiaire comprenant au moins un rail de support de sièges passant par la traverse de support correspondante.Optionally, the rail vehicle comprises, for each additional floor element, a respective support crossmember, connected to the frame, and on which the additional floor element partially rests, each intermediate floor comprising at least one support rail. seats passing through the corresponding support crossmember.

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 figures annexées, parmi lesquelles :

  • [Fig 1] La figure 1 est une vue partielle en coupe longitudinale d'une voiture à deux étages selon un premier exemple de mode de réalisation de l'invention ;
  • [Fig 2] La figure 2 est une vue en coupe transversale de la voiture de la figure 1 ;
  • [Fig 3] La figure 3 est une vue similaire à la figure 2 d'une voiture à deux étages selon un deuxième exemple de mode de réalisation de l'invention ;
  • [Fig 4] La figure 4 est une vue en perspective d'une trappe équipant la voiture de la figure 1.
The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the appended figures, among which:
  • [ Fig 1 ] The figure 1 is a partial view in longitudinal section of a two-story car according to a first exemplary embodiment of the invention;
  • [ Fig 2 ] The figure 2 is a cross-sectional view of the car from the figure 1 ;
  • [ Fig 3 ] The figure 3 is a view similar to the figure 2 a double-decker car according to a second exemplary embodiment of the invention;

On a représenté sur la figure 1 une voiture à deux étages selon un premier exemple de mode de réalisation. Cette voiture à deux étages est désignée par la référence générale 10.We have represented on the figure 1 a double-decker car according to a first exemplary embodiment. This double-decker car is designated by the general reference 10.

La voiture à deux étages 10 est de conception générale classique à l'exception des éléments de l'invention décrits ci-après.The double-decker car 10 is of conventional general design with the exception of the elements of the invention described below.

La voiture à deux étages 10 comporte un étage supérieur 12 agencé au-dessus d'un étage inférieur 14.The two-stage car 10 has an upper stage 12 arranged above a lower stage 14.

L'étage supérieur 12 et l'étage inférieur 14 sont séparés par un plancher intermédiaire 16, qui forme donc un plancher pour l'étage supérieur 12 et un plafond pour l'étage inférieur 14.The upper stage 12 and the lower stage 14 are separated by an intermediate floor 16, which therefore forms a floor for the upper stage 12 and a ceiling for the lower stage 14.

L'étage supérieur 12 comporte des sièges supérieurs 18 destinés à recevoir des passagers.The upper floor 12 has upper seats 18 intended to receive passengers.

L'étage inférieur 14 comporte des sièges inférieurs 20 destinés à recevoir des passagers. Chaque siège inférieur 20 comporte un dossier 20a et une assise 20b.The lower stage 14 includes lower seats 20 intended to receive passengers. Each lower seat 20 has a back 20a and a seat 20b.

Le plancher intermédiaire 16 selon l'invention comporte un cadre 22 (visible sur la figure 4) délimitant une ouverture de passage 24 pour une personne. Cette ouverture de passage 24 permet l'évacuation des passagers depuis l'étage supérieur 12 vers l'étage inférieur 14.The intermediate floor 16 according to the invention comprises a frame 22 (visible on the figure 4 ) delimiting a passage opening 24 for a person. This passage opening 24 allows the evacuation of passengers from the upper stage 12 to the lower stage 14.

Dans l'exemple décrit, le cadre 22 présente une longueur de 859 mm, une largeur de 760 mm, et une hauteur de 49 mm. Le cadre 22 comporte par ailleurs un rebord intérieur 23 de 20 mm de large et de 19 mm de hauteurIn the example described, the frame 22 has a length of 859 mm, a width of 760 mm, and a height of 49 mm. The frame 22 also has an inner rim 23 20 mm wide and 19 mm high

Le cadre 22 est par exemple réalisé en aluminium.The frame 22 is for example made of aluminum.

L'ouverture de passage 24 est obturée au moins en partie par une trappe amovible 26. Cette trappe 26 est en position fermée lorsqu'elle repose sur le rebord intérieur 23.The passage opening 24 is closed at least in part by a removable hatch 26. This hatch 26 is in the closed position when it rests on the inner rim 23.

Comme cela est représenté sur la figure 4, la trappe amovible 26 comporte au moins un loquet 28 mobile entre une position en saillie depuis un bord 30 respectif de la trappe 26 et une position escamotée. En position escamotée, le loquet 28 est escamoté dans le bord 30.As shown in the figure 4 , the removable hatch 26 comprises at least one movable latch 28 between a projecting position from a respective edge 30 of the hatch 26 and a retracted position. In the retracted position, the latch 28 is retracted into the edge 30.

Le cadre 22 comporte, pour chaque loquet mobile 28, une gâche complémentaire 32 destinée à recevoir ce loquet mobile 28 en position en saillie. Cette gâche 32 présente par exemple une forme générale oblongue.The frame 22 comprises, for each movable latch 28, a complementary keeper 32 intended to receive this movable latch 28 in the projecting position. This keeper 32 has for example a generally oblong shape.

La trappe 26 présente par exemple une forme générale rectangulaire, et comporte par exemple au moins un loquet mobile 28 sur chaque bord 30 de ce rectangle.The hatch 26 has for example a generally rectangular shape, and comprises for example at least one movable latch 28 on each edge 30 of this rectangle.

En variante, au moins l'un des bords 30 ne comporte pas de loquet mobile 28. Dans ce cas, l'un de ces bords 30 sans loquet mobile 28 comporte une saillie fixe. Ainsi, lors de la mise en place de la trappe 26, la trappe 26 est inclinée pour insérer la saillie fixe dans une gâche 32 correspondante, avant de basculer la trappe en position de fermeture. La trappe 26 est ensuite verrouillée dans le cadre 22 grâce à chaque loquet mobile 28.As a variant, at least one of the edges 30 does not have a movable latch 28. In this case, one of these edges 30 without movable latch 28 has a fixed projection. Thus, during the installation of the hatch 26, the hatch 26 is inclined to insert the fixed projection in a corresponding keeper 32, before tilting the hatch in the closed position. The hatch 26 is then locked in the frame 22 by each movable latch 28.

La trappe 26 comporte par ailleurs un mécanisme de déplacement du loquet 28, de type classique. Le mécanisme de déplacement comprenant une serrure 34 et une clé 36 correspondant à la serrure 34, tel que l'actionnement de la clé 36 dans la serrure 34 entraîne le déplacement de chaque loquet 28. La clé est par exemple une clé à section transversale polygonale, par exemple carrée.The hatch 26 also comprises a mechanism for moving the latch 28, of the conventional type. The movement mechanism comprising a lock 34 and a key 36 corresponding to the lock 34, such that the actuation of the key 36 in the lock 34 causes the displacement of each latch 28. The key is for example a key with polygonal cross section , for example square.

Le mécanisme comporte par exemple un élément rotatif lié en rotation avec la serrure 34, et, pour chaque loquet 28, une tringle reliant ce loquet 28 à l'élément rotatif.The mechanism comprises for example a rotary element linked in rotation with the lock 34, and, for each latch 28, a rod connecting this latch 28 to the rotary element.

La clé 36 est portée par un outil de déverrouillage 38 en forme de T, comprenant une branche principale 40 s'étendant entre une extrémité libre formant la clé 36, et une extrémité liée à deux branches de préhension 42.The key 36 is carried by a T-shaped unlocking tool 38, comprising a main branch 40 extending between a free end forming the key 36, and one end linked to two gripping branches 42.

Au moins l'une des branches de préhension 42 est reliée à la branche principale 40 par une liaison pivot 44 d'axe perpendiculaire à la branche principale 40 et à cette branche de préhension 42. De préférence, les deux branches de préhension 42 sont ainsi articulées par rapport à la branche principale 40, si bien que l'outil de déverrouillage 38 est repliable.At least one of the gripping branches 42 is connected to the main branch 40 by a pivot connection 44 of axis perpendicular to the main branch 40 and to this gripping branch 42. Preferably, the two gripping branches 42 are thus articulated with respect to the main branch 40, so that the unlocking tool 38 is foldable.

L'outil de déverrouillage 38 peut ainsi être rangé dans un boîtier prévu à cet effet, disposé à l'étage supérieur 12 de la même manière qu'un boîtier de rangement de marteau brise-vitre de l'état de la technique.The unlocking tool 38 can thus be stored in a box provided for this purpose, arranged on the upper stage 12 in the same manner as a glass breaker hammer storage box of the prior art.

La trappe 26 comporte par ailleurs au moins une poignée de préhension 45, permettant de soulever la trappe 26 et la manipuler pour l'extraire du cadre 22.The hatch 26 also comprises at least one grip handle 45, making it possible to lift the hatch 26 and handle it to extract it from the frame 22.

Comme cela est notamment représenté sur la figure 2, et également sur la figure 3 qui sera décrite ultérieurement, l'ouverture de passage 24 est agencée au moins en partie au-dessus de l'assise 20b d'au moins l'un des sièges inférieurs 20. Ainsi, en passant par l'ouverture de passage 24, un passager peut descendre sur l'assise 20b avant de descendre au sol. La descente par le passage 24 est ainsi simplifiée.As shown in particular in the figure 2 , and also on the figure 3 which will be described later, the passage opening 24 is arranged at least in part above the seat 20b of at least one of the lower seats 20. Thus, passing through the passage opening 24, a passenger can descend on seat 20b before descending to the ground. The descent through passage 24 is thus simplified.

Comme cela est représenté sur la figure 1, l'étage inférieur 14 est délimité transversalement par des parois munies de fenêtres 46, l'ouverture de passage 24 étant agencée de sorte qu'un plan transversal 48 passant par cette ouverture de passage 24 passe par l'une des fenêtres 46.As shown in the figure 1 , the lower stage 14 is delimited transversely by walls provided with windows 46, the passage opening 24 being arranged so that a transverse plane 48 passing through this passage opening 24 passes through one of the windows 46.

Plus particulièrement, les fenêtres d'au moins l'une des parois étant alignées entre deux fenêtres d'extrémités, l'ouverture de passage 24 est agencée de sorte que ledit plan transversal 48 passe par l'une des fenêtres d'extrémité.More particularly, the windows of at least one of the walls being aligned between two end windows, the passage opening 24 is arranged so that said transverse plane 48 passes through one of the end windows.

Ainsi, si l'évacuation de la voiture 10 doit s'effectuer par une fenêtre, l'ouverture de passage 24 se situe à proximité immédiate de cette fenêtre. En revanche, si l'évacuation peut s'effectuer par la sortie principale, l'ouverture de passage 24 est proche de la sortie.Thus, if the evacuation of the car 10 must take place through a window, the passage opening 24 is located in the immediate vicinity of this window. On the other hand, if the evacuation can be carried out by the main exit, the passage opening 24 is close to the exit.

De préférence, le plan transversal 48 est un plan médian de l'ouverture de passage 24, et un plan médian de la fenêtre 46 correspondante.Preferably, the transverse plane 48 is a median plane of the passage opening 24, and a median plane of the corresponding window 46.

Avantageusement, la trappe 26 est recouverte par un tapis (non représenté) fixé au sol par des moyens amovibles (attaches Velcro ou boutons pression) ou aisément destructibles (collage d'intensité modérée).Advantageously, the hatch 26 is covered by a carpet (not shown) fixed to the ground by removable means (Velcro fasteners or snaps) or easily destructible (bonding of moderate intensity).

Il est à noter qu'un véhicule ferroviaire comporte généralement au moins une zone de première classe et au moins une zone de seconde classe (moins luxueuse que la zone de première classe).It should be noted that a railway vehicle generally comprises at least one first class zone and at least one second class zone (less luxurious than the first class zone).

Il est avantageux d'utiliser le même plancher intermédiaire 16 pour une zone de première classe que pour une zone de seconde classe, pour des raisons de standardisation. L'ouverture de passage 24 se trouve donc au même endroit dans une zone de première classe et dans une zone de seconde classe. Or, les sièges ne sont pas disposés de la même manière dans une zone de première classe (voir figure 2) et dans une zone de seconde classe (voir figure 3).It is advantageous to use the same intermediate floor 16 for a first class zone as for a second class zone, for reasons of standardization. The passage opening 24 is therefore in the same place in a first class area and in a second class area. However, the seats are not arranged in the same way in a first class area (see figure 2 ) and in a second class area (see figure 3 ).

L'ouverture de passage 24 est donc prévue suffisamment large pour couvrir les deux cas de figure, cette ouverture de passage 24 étant en partie obturée par au moins un élément de plancher additionnel qui sera recouvert par un siège 18.The passage opening 24 is therefore provided wide enough to cover both cases, this passage opening 24 being partly closed by at least one additional floor element which will be covered by a seat 18.

Le premier mode de réalisation décrit, représenté sur les figures 2 et 4, correspond à une zone de première classe, et le second mode de réalisation qui sera ultérieurement décrit, représenté sur la figure 3, correspond à une zone de seconde classe.The first embodiment described, represented on the figures 2 and 4 , corresponds to a first class area, and the second embodiment which will be later described, shown in the figure 3 , corresponds to a second class area.

Conformément au premier mode de réalisation, une partie transversale de l'ouverture de passage 24 est recouverte par un premier élément de plancher additionnel 50. Ce premier élément de plancher additionnel 50 repose sur le rebord 23 dans ladite partie transversale.According to the first embodiment, a transverse part of the passage opening 24 is covered by a first additional floor element 50. This first additional floor element 50 rests on the flange 23 in said transverse part.

Par ailleurs, une première traverse de support 52 s'étend au travers du cadre 22, reposant sur le rebord 23, le premier élément de plancher additionnel 50 étant connecté à cette première traverse de support 52.Furthermore, a first support cross member 52 extends through the frame 22, resting on the rim 23, the first additional floor element 50 being connected to this first support cross member 52.

En variante, le premier élément de plancher additionnel et la première traverse de support sont formés par un unique élément.As a variant, the first additional floor element and the first support cross-member are formed by a single element.

La première traverse de support 52 comporte un rebord 54 destiné à recevoir un bord de la trappe 26.The first support cross-member 52 has a flange 54 intended to receive an edge of the hatch 26.

Le plancher intermédiaire 16 comprend un premier rail 56 de support de sièges, passant par la première traverse de support 52, parallèlement à cette première de support, ce premier rail 56 étant fixé à cette traverse de support 52. Un second rail 57, parallèle au premier rail 56, est fixé au plancher intermédiaire 16, de l'autre côté de l'ouverture de passage 24, au-delà de cette ouverture de passage 24.The intermediate floor 16 comprises a first rail 56 for supporting seats, passing through the first support crosspiece 52, parallel to this first support, this first rail 56 being fixed to this support crosspiece 52. A second rail 57, parallel to the first rail 56, is fixed to the intermediate floor 16, on the other side of the passage opening 24, beyond this passage opening 24.

On notera que les dimensions du passage non obturé par le premier élément de plancher additionnel et la traverse de support sont suffisantes pour permettre le passage de personnes. Ces dimensions correspondent à celles de la trappe 26, qui est la même pour les zones de première et de seconde classes.Note that the dimensions of the passage not blocked by the first additional floor element and the support cross member are sufficient to allow the passage of people. These dimensions correspond to those of the hatch 26, which is the same for the first and second class areas.

Dans le second mode de réalisation, correspondant à la zone de seconde classe et étant représenté sur la figure 3, deux parties transversales de l'ouverture de passage 24 sont recouvertes par des seconds éléments de plancher additionnels 58 respectifs.In the second embodiment, corresponding to the second class area and being represented on the figure 3 , two transverse parts of the passage opening 24 are covered by respective second additional floor elements 58.

De la même façon que dans le premier mode de réalisation, chaque second élément de plancher additionnel 58 est connecté à une seconde traverse de support 60.In the same way as in the first embodiment, each second additional floor element 58 is connected to a second support cross-member 60.

Deux rails de support de sièges passent alors chacun sur l'une respective des secondes traverses de support 60.Two seat support rails then each pass over a respective one of the second support crosspieces 60.

Les secondes traverses de support 60 comportent chacune un rebord destiné à recevoir un bord de la trappe 26.The second support sleepers 60 each have a rim intended to receive an edge of the hatch 26.

La trappe 26 présente les mêmes dimensions que celle équipant la zone de première classe.The hatch 26 has the same dimensions as that fitted to the first class area.

On notera que l'invention n'est pas limitée aux modes de réalisation précédemment décrits, et pourrait présenter diverses variantes complémentaires.It will be noted that the invention is not limited to the embodiments described above, and could present various complementary variants.

En particulier, les zones de première et de seconde classes peuvent être agencées dans une même voiture ou dans des voitures distinctes.In particular, the first and second class areas can be arranged in the same car or in separate cars.

Conformément à une variante, seules des voitures d'extrémité du véhicule ferroviaire sont munies d'ouvertures de passage 24 telles que décrites précédemment.According to a variant, only end cars of the rail vehicle are provided with through openings 24 as described above.

Il est également à noter qu'une évacuation classique par une fenêtre du second étage reste envisageable, dans le cas où une évacuation par l'étage inférieur ne serait pas possible.It should also be noted that a conventional evacuation through a window on the second floor remains possible, in the event that an evacuation through the lower floor is not possible.
