Definitions

  • the present invention relates to a vehicle, in particular a railway vehicle, comprising at least one upper room and one lower room respectively for passengers, a side wall comprising a first zone located in the upper room, and at least a second zone located in the lower room, and a ventilation system adapted to create at least a first air flow along the first zone, and at least a second air flow along the second zone.
  • the hopper forms a horizontal opening providing permanent communication between the upper room and the lower room.
  • the hopper is arranged adjacent to the side wall, and the first air flow descends towards the hopper, while the second air flow rises towards the hopper, there is a risk of anarchic circulation of the air flows between the upper room and the lower room likely to have very negative consequences on the thermal comfort of passengers. In other words, the temperature and ventilation settings selected for the upper room will potentially negatively influence the atmosphere in the lower room, and vice versa.
  • an object of the invention is to provide a vehicle comprising a permanent hopper and improving the thermal comfort of passengers present in the upper room or the lower room.
  • the vehicle 10 is a railway vehicle.
  • the vehicle 10 is for example a road vehicle, in particular a bus or a coach, a ship or an aircraft.
  • the vehicle 10 comprises a body structure 12 defining an upper room 14 and a lower room 16.
  • the vehicle 10 can have more than two levels.
  • the vehicle 10 comprises a floor 18 of the lower room 16, a floor 20 of the upper room 14 and a ceiling 22.
  • the vehicle 10 also comprises two side walls 24, 26 opposite in a transverse direction T substantially parallel to the floor 20.

  • the ventilation system 36 is also adapted to create two transverse air flows 58, 60, directed one towards the other, substantially along the floor 18.
  • the ventilation system 36 is also adapted to create two transverse air flows 62, 64, directed towards each other, along the ceiling 22.
  • the ventilation system 36 is advantageously masked by the plurality 32 of trim members in a manner known per se.
  • the hopper 30 has for example a rectangular shape in view along the elevation direction V.
  • the hopper 30 is advantageously surrounded at least partially by a balustrade 66.
  • the hopper 30 is transversely adjacent to the side wall 24. In other words, the hopper 30 is closer to the side wall 24 than to the side wall 26. For example, the hopper 30 is located less than 50 cm from the side wall 24.
  • the hopper 30 does not extend beyond the median plane P towards the side wall 26.
  • the balustrade 66 comprises for example a portion 68 located on the side opposite the side wall 24 with respect to the hopper 30 in the transverse direction T.
  • the portion 68 of the balustrade is for example substantially perpendicular to the transverse direction T.
  • the trim member 34 is fixed to the side wall 24 and extends from the first zone 38 to the second zone in the direction of elevation V.
  • the covering member 34 projects transversely with respect to the first zone 38 and to the second zone 42.
  • the covering member advantageously has a transverse extension E measured from the side wall 24, for example between 5 cm and 35 cm.
  • the trim member 34 defines a first guide surface 70 adapted to deflect the first airflow 40 and form a third airflow 72 located above the floor 20 and oriented substantially transversely.
  • the trim member also defines a second guide surface 74 adapted to deflect the second airflow 44 and form a fourth airflow 76 located below the floor 20 and oriented substantially transversely.
  • the covering member 34 comprises an upper part 78 adjacent to the first zone 38 and defining the first guide surface 70, an intermediate part 80, and a lower part 82 adjacent to the second zone 42 and defining the second guide surface 74.
  • the trim member 34 advantageously extends along the windows 46, 48 in the longitudinal direction L. As a variant, it extends longitudinally along several windows.
  • the trim member 34 has, for example, a generally rectangular shape in view along the transverse direction T.
  • the covering member 34 is adapted so that the third airflow 72 is directed towards an upper half of the portion 68 of the balustrade 66. According to a variant not shown, the covering member is configured so that the third airflow is directed above the balustrade 66.
  • first guide surface 70 and the second guide surface 74 respectively comprise proximal surfaces 84, 86 relative to the side wall 24 in the transverse direction T, the proximal surfaces being concave.
  • only one of the guide surfaces comprises such a concave proximal surface.
  • the first guide surface 70 and the second guide surface 74 respectively comprise flats 88, 90 substantially parallel to the transverse direction T.
  • only one of the guide surfaces comprises such a flat.
  • the first guide surface and the second guide surface respectively comprise distal surfaces 92, 94 with respect to the side wall 24 according to the transverse direction T, the distal surfaces respectively forming spouts projecting relative to the intermediate part 80 in the transverse direction T.
  • only one of the guide surfaces forms such a beak.
  • one and/or the other of the distal surfaces 92, 94 are rounded around the longitudinal direction L and do not form a beak.
  • the intermediate part 80 defines for example a substantially planar surface 96 connecting the first guide surface 70 to the second guide surface 74.
  • the covering member 34 is adapted so that the third flow of air 72 is directed towards an upper half of the portion 68 of the balustrade 66.
  • the covering member is configured so that the third flow of air is directed above the balustrade 66.
  • the ventilation system 36 creates the first flow of air 40 which descends along the window 46, the second flow of air 44, which rises along the window 48, as well as the other airflows 54, 56, 58, 60, 62 and 64.
  • the covering member 34 In the absence of the covering member 34, there would be a risk that the first airflow 40 would continue its downward stroke through the hopper 30, crossing the second airflow 44 which would continue its upward stroke. through the hopper. This would create an anarchic circulation of the air flows, in which the settings, in particular of temperature, desired for the upper room 14 would be communicated to the lower room 16, and vice versa.
  • the covering member 34 is adapted to prevent such anarchic circulation.
  • first guide surface 70 deflects the first airflow 40 and forms the third airflow 72 oriented transversely.
  • second guide surface 74 deflects the second air flow 44 and forms the fourth air flow 76 also oriented transversely and located under the floor 20.
  • the fourth air flow 76 remains overwhelmingly in the lower room 16.
  • the fourth air flow 76 is deflected for example downwards (arrow F1) on the figure 1 when it encounters a flow (arrow F2) resulting from the deflection of the air flow 56 by the floor 20.
  • the third flow of air 72 abuts on the portion 68 of the balustrade 66. Due to the presence of the fourth flow of air 76 and the flow materialized by the arrow F1, the third flow of air 72 goes mainly upwards and therefore remains in the upper room 14.
  • the third air flow 72 passes directly above the balustrade 66.
  • the air flow 54 descends along the window 50 and forms a roll (arrows F5 and F6). Airflow 54 eventually rises along balustrade 66.
  • the airflows 62, 64 meet and descend. However, these descending flows do not pass through the hopper 30 in the direction of the lower room 16 due to the presence of opposing air flows from the third air flow 72 and the flow represented by the arrow F6.
  • the proximal surfaces 84, 86 are used to detach respectively the first air flow 40 and the second air flow 44 from the first zone 38 and from the second zone 42.
  • the flats 88, 90 give their directions respectively to the third flows of air 72 and to the fourth air flow 76.
  • the nozzles formed by the distal surfaces 92, 94 allow focusing of the third air flow 72 and of the fourth air flow 76 and prevent part of these flows diffuse towards the hopper 30.
  • the covering member 34 thanks to its reduced transverse extension E, is compact and does not bother travelers when they take the stairs 28.
  • the covering member advantageously made up of a single piece, is easily installed and is inexpensive.
  • it does not require any particular adaptation of the other parts of the vehicle 10.
