Dans la suite, les termes d'orientation s'entendent en référence au repère orthogonal usuel des véhicules ferroviaires, représenté sur les Figures, et dans lequel on distingue :

  • un axe longitudinal X, orienté de l'arrière vers l'avant,
  • un axe transversal Y, orthogonal à l'axe X en étant orienté de la droite vers la gauche et définissant avec l'axe X un plan horizontal, et
  • un axe vertical Z, orthogonal aux axes X et Y en étant orienté du bas vers le haut, ledit axe vertical Z définissant avec l'axe longitudinal X un plan longitudinal et avec l'axe transversal Y un plan transversal.
In the following, the orientation terms are understood with reference to the usual orthogonal reference frame of railway vehicles, shown in the figures, and in which there are:
  • a longitudinal axis X, oriented from the rear towards the front,
  • a transverse axis Y, orthogonal to the X axis being oriented from right to left and defining with the X axis a horizontal plane, and
  • a vertical axis Z, orthogonal to the X and Y axes being oriented from bottom to top, said vertical axis Z defining with the longitudinal axis X a longitudinal plane and with the transverse axis Y a transverse plane.

La direction d'élongation E-E' est notamment confondue avec la direction longitudinale X.The elongation direction E-E 'is notably coincident with the longitudinal direction X.

Le châssis 12 délimite l'habitacle 16 vers le bas en définissant un plancher de l'habitacle 16.The frame 12 delimits the cockpit 16 downwards by defining a floor of the cockpit 16.

La carrosserie 14 comprend un pavillon 20 délimitant l'habitacle 16 vers le haut et deux parois latérales 22 (seule la paroi latérale 22 gauche étant visible sur la Figure 1) délimitant l'habitacle 16 vers la gauche et vers la droite.The bodywork 14 comprises a roof 20 defining the cockpit 16 upwards and two side walls 22 (only the left side wall 22 being visible on the Figure 1 ) delimiting the passenger compartment 16 to the left and to the right.

These through openings 24, 26, 28 include large openings 24 forming doors. access to the passenger compartment 16, intermediate openings 26 forming windows closed by windows (not shown), and small openings 28 in the form of slots elongate in the longitudinal direction X, said openings 28 being disposed above the windows 26 .

A l'intérieur de chaque ouverture 28 est logé un boîtier d'aération identique au boîtier 30 représenté sur la Figure 2.Inside each opening 28 is housed a ventilation box identical to the housing 30 shown in FIG. Figure 2 .

Ce boîtier 30 est passif, c'est-à-dire qu'il ne comprend aucun actionneur motorisé. Il est de préférence obtenu par fabrication additive de matière plastique.This housing 30 is passive, that is to say it does not include any motorized actuator. It is preferably obtained by additive manufacturing of plastics material.

Comme visible sur les Figures 2 et 3, ce boîtier 30 est allongé suivant la direction longitudinale X et présente une première face latérale 32 et une deuxième face latérale 34 espacées l'une de l'autre suivant la direction transversale Y. Il comprend également un cadre 36 sensiblement plan interposé entre les faces latérales 32, 34, ledit cadre 36 s'étendant suivant un plan longitudinal sensiblement perpendiculaire à la direction transversale Y. Par « s'étendant suivant un plan longitudinal », on comprend que les dimensions principales du cadre 36 sont mesurées selon des directions parallèles audit plan.As visible on Figures 2 and 3 this housing 30 is elongate in the longitudinal direction X and has a first lateral face 32 and a second lateral face 34 spaced from each other in the transverse direction Y. It also comprises a substantially plane frame 36 interposed between the faces 32, 34, said frame 36 extending in a longitudinal plane substantially perpendicular to the transverse direction Y. By "extending in a longitudinal plane", it is understood that the main dimensions of the frame 36 are measured in directions parallel to said plan.

La première face latérale 32 est disposée à l'extérieur de l'habitacle 16. Elle est inclinée vers le bas, c'est-à-dire que la direction normale à ladite face latérale 32 et orientée depuis cette dernière à l'opposé du boîtier 30 a une composante selon la direction verticale Z pointant vers le bas.The first lateral face 32 is disposed outside the passenger compartment 16. It is inclined downwards, that is to say that the direction normal to said lateral face 32 and oriented from the latter to the opposite of the Case 30 has a component in the vertical direction Z pointing downwards.

La première face latérale 32 est en particulier sensiblement plane et forme avec le plan longitudinal un angle α compris entre 0 et 20°.The first lateral face 32 is in particular substantially plane and forms with the longitudinal plane an angle α of between 0 and 20 °.

La première face latérale 32 est allongée suivant la direction longitudinale X.The first lateral face 32 is elongate in the longitudinal direction X.

La première face latérale 32 présente un bord supérieur 41 et un bord inférieur 42 sensiblement horizontaux. La première face latérale 32 présente encore deux bords d'extrémité longitudinale 43 (Figure 4) chacun sensiblement compris dans un plan transversal.The first side face 32 has an upper edge 41 and a lower edge 42 substantially horizontal. The first lateral face 32 still has two longitudinal end edges 43 ( Figure 4 ) each substantially in a transverse plane.

La deuxième face latérale 34 est disposée à l'intérieur de l'habitacle 16. Elle est inclinée vers le haut, c'est-à-dire que la direction normale à ladite face latérale 34 et orientée depuis cette dernière à l'opposé du boîtier 30 a une composante selon la direction verticale Z pointant vers le haut.The second lateral face 34 is disposed inside the passenger compartment 16. It is inclined upwards, that is to say that the direction normal to said lateral face 34 and oriented from the latter opposite the housing 30 has a component in the vertical direction Z pointing upwards.

La deuxième face latérale 34 est en particulier sensiblement plane et forme avec le plan longitudinal un angle β compris entre 0 et 45°.The second lateral face 34 is in particular substantially plane and forms with the longitudinal plane an angle β between 0 and 45 °.

La deuxième face latérale 34 est allongée suivant la direction longitudinale X. Elle a une extension suivant ladite direction X inférieur à l'extension de la première face latérale 32 suivant la direction X.The second lateral face 34 is elongate in the longitudinal direction X. It has an extension along said direction X less than the extension of the first lateral face 32 in the direction X.

La deuxième face latérale 34 présente un bord inférieur 44 et un bord supérieur 45 sensiblement horizontaux. Le bord 44 est disposé plus haut que le bord inférieur 42 de la première face 32. Le bord 45 est disposé plus haut que le bord supérieur 41 de la première face 32.The second side face 34 has a lower edge 44 and a substantially horizontal upper edge 45. The edge 44 is disposed higher than the lower edge 42 of the first face 32. The edge 45 is disposed higher than the upper edge 41 of the first face 32.

La deuxième face latérale 34 présente encore deux bords d'extrémité longitudinale 46 chacun sensiblement compris dans un plan transversal. Ces bords 46 sont encadrés longitudinalement par les bords 43 de la première face 32.The second lateral face 34 further has two longitudinal end edges 46 each substantially in a transverse plane. These edges 46 are bordered longitudinally by the edges 43 of the first face 32.

Le cadre 36 comprend un bord supérieur 50, un bord inférieur 51, et deux bords d'extrémité longitudinale 52. Les bords 50, 51 encadrent verticalement les bords supérieurs 41, 45 et les bords inférieurs 42, 44 des première et deuxième faces 32, 34, et les bords 52 encadrent longitudinalement les bords d'extrémité longitudinale 43, 46 des première et deuxième faces 32, 34.The frame 36 comprises an upper edge 50, a lower edge 51, and two longitudinal end edges 52. The edges 50, 51 vertically enclose the upper edges 41, 45 and the lower edges 42, 44 of the first and second faces 32, 34, and the edges 52 flank longitudinally the longitudinal end edges 43, 46 of the first and second faces 32, 34.

Le boîtier 30 comprend en outre une plaque inférieure 54, une première plaque supérieure 56, une deuxième plaque supérieure 58, et deux plaques d'extrémité longitudinale 60.The housing 30 further comprises a lower plate 54, a first upper plate 56, a second upper plate 58, and two longitudinal end plates 60.

La plaque inférieure 54 est sensiblement plane. Elle s'étend transversalement depuis la première face latérale 32 jusqu'à la deuxième face latérale 34 en s'étendant à travers le cadre 36. Elle relie en particulier le bord inférieur 42 de la première face 32 au bord inférieur 44 de la deuxième face 34. Elle est inclinée par rapport au cadre 36 et forme avec le cadre 36, dans un plan transversal, un angle γ compris entre 0 et 45°.The lower plate 54 is substantially flat. It extends transversely from the first lateral face 32 to the second lateral face 34 extending through the frame 36. It connects in particular the lower edge 42 of the first face 32 to the lower edge 44 of the second face 34. It is inclined relative to the frame 36 and forms with the frame 36, in a transverse plane, an angle γ between 0 and 45 °.

La première plaque supérieure 56 est sensiblement plane. Elle s'étend transversalement depuis la première face latérale 32 jusqu'au cadre 36 en reliant le bord supérieur 41 de la première face 32 au cadre 36.The first top plate 56 is substantially planar. It extends transversely from the first lateral face 32 to the frame 36 by connecting the upper edge 41 of the first face 32 to the frame 36.

La deuxième plaque supérieure 58 est sensiblement plane. Elle s'étend transversalement depuis la deuxième face latérale 34 jusqu'au cadre 36 en reliant le bord supérieur 45 de la deuxième face 34 au cadre 36.The second upper plate 58 is substantially flat. It extends transversely from the second lateral face 34 to the frame 36 by connecting the upper edge 45 of the second face 34 to the frame 36.

Chacune des plaques d'extrémité longitudinale 60 s'étend transversalement depuis la première face latérale 32 jusqu'à la deuxième face latérale 34 en s'étendant à travers le cadre 36. Elle relie en particulier un bord d'extrémité longitudinale 43 respectif de la première face 32 à un bord d'extrémité longitudinale 46 respectif de la deuxième face 34.Each of the longitudinal end plates 60 extends transversely from the first side face 32 to the second side face 34 extending through the frame 36. In particular, it connects a respective longitudinal end edge 43. from the first face 32 to a respective longitudinal end edge 46 of the second face 34.

Comme visible sur la Figure 4, chaque plaque d'extrémité longitudinale 60 présente un premier tronçon 62 arqué, à concavité orientée vers la première face 32, suivi immédiatement d'un deuxième tronçon 64 transversal en contact avec la deuxième face 34. Elle présente également, à l'interface entre les premier et deuxième tronçons 62, 64, un point de rebroussement 66.As visible on the Figure 4 each longitudinal end plate 60 has a first arcuate section 62 with concavity oriented towards the first face 32, immediately followed by a second transverse section 64 in contact with the second face 34. It also has, at the interface between the first and second sections 62, 64, a cusp 66.

En référence à la Figure 4, lesdites plaques 54, 56, 58, 60 délimitent entre elles un espace de circulation d'air 68 entre les première et deuxième faces latérales 32, 34.With reference to the Figure 4 said plates 54, 56, 58, 60 delimit between them an air circulation space 68 between the first and second lateral faces 32, 34.

Le boîtier 30 définit intérieurement, dans l'espace de circulation d'air 68, une pluralité de conduits 70 accolés les uns aux autres suivant la direction longitudinale X, chaque conduit 70 débouchant dans la première face latérale 32 à travers une première ouverture 72, et dans la deuxième face latérale 34 à travers une deuxième ouverture 74.The housing 30 internally defines, in the air circulation space 68, a plurality of ducts 70 contiguous to each other in the longitudinal direction X, each duct 70 opening into the first side face 32 through a first opening 72, and in the second side face 34 through a second opening 74.

Chaque première ouverture 72 s'étend depuis le bord inférieur 42 jusqu'au bord supérieur 41 de la première face 32, et chaque deuxième ouverture 74 s'étend depuis le bord inférieur 44 jusqu'au bord supérieur 45 de la deuxième face 34. Ainsi, pour chaque conduit 64, la première ouverture 72 est disposée plus bas que la deuxième ouverture 74.Each first opening 72 extends from the lower edge 42 to the upper edge 41 of the first face 32, and each second opening 74 extends from the lower edge 44 to the upper edge 45 of the second face 34. for each duct 64, the first opening 72 is arranged lower than the second opening 74.

La paroi inférieure 54 définit un fond de ces conduits 70.The bottom wall 54 defines a bottom of these ducts 70.

Lesdits conduits 70 sont séparés les uns des autres par des séparateurs 76 présentant chacun une section horizontale en forme de T dont le pied 78 est orienté sensiblement transversalement. Ces séparateurs 76 sont disposés en quinconce, successivement les uns aux autres suivant la direction longitudinale X, le pied 78 du T étant dirigé alternativement vers la première face 32 et vers la deuxième face 34. Ainsi, chaque conduit 70 comprend une partie de conduit présentant une section principale, prise selon un plan horizontal, en forme de chicane, c'est-à-dire présentant au moins un point d'inflexion. Dans l'exemple représenté, cette partie de conduit constitue l'intégralité du conduit 70. Le plan horizontal comprend la direction longitudinale X et la direction transversale Y.Said conduits 70 are separated from each other by separators 76 each having a T-shaped horizontal section whose foot 78 is oriented substantially transversely. These separators 76 are arranged in staggered rows, successively to each other in the longitudinal direction X, the foot 78 of the T being directed alternately towards the first face 32 and towards the second face 34. Thus, each duct 70 comprises a portion of duct presenting a main section, taken along a horizontal plane, in the form of a chicane, that is to say having at least one point of inflection. In the example shown, this duct portion constitutes the entirety of the duct 70. The horizontal plane comprises the longitudinal direction X and the transverse direction Y.

En variante, chaque conduit 70 comprend une partie de conduit présentant une section principale, prise dans un plan vertical, en forme de chicane, c'est-à-dire présentant au moins un point d'inflexion. Le plan vertical comprend la direction verticale Z et la direction transversale Y.Alternatively, each duct 70 comprises a duct portion having a main section, taken in a vertical plane, in the form of a chicane, that is to say having at least one point of inflection. The vertical plane includes the vertical direction Z and the transverse direction Y.

Plus généralement, chaque conduit 70 comprend une partie de conduit présentant une section principale, prise dans un plan principal parallèle à la direction transversale Y, en forme de chicane.More generally, each duct 70 comprises a duct portion having a main section, taken in a main plane parallel to the transverse direction Y, in the shape of a chicane.

Lorsque le pied 78 du T est orienté vers la deuxième face 34, la barre 80 du T affleure la première face 32. Lorsque le pied 78 du T est orienté vers la première face 32, la barre 80 du T s'étend sensiblement parallèlement à la deuxième face 34, en léger retrait vers l'intérieur du boîtier 30 relativement à ladite deuxième face 34. Par « en léger retrait », on comprend que la distance de la barre 80 du T à la deuxième face 34 est par exemple inférieure à 50 mm, de préférence à 30 mm.When the foot 78 of the T is oriented towards the second face 34, the bar 80 of the T is flush with the first face 32. When the foot 78 of the T is oriented towards the first face 32, the bar 80 of the T extends substantially parallel to the second face 34, slightly inwardly withdrawing from the housing 30 relative to said second face 34. By "slightly shrinking", it is understood that the distance from the bar 80 of the T to the second face 34 is for example less than 50 mm, preferably 30 mm.

Chaque séparateur 76 présente deux cornes 82 faisant chacune saille depuis une extrémité de la barre 80 du T, vers l'intérieur du boîtier 30, en particulier en s'écartant du pied 78, jusqu'à une extrémité libre 84 disposée à sensiblement mi-distance des faces 32, 34.Each separator 76 has two horns 82 each projecting from one end of the bar 80 of the T, towards the inside of the housing 30, in particular by moving away from the foot 78, to a free end 84 arranged at substantially distance of the faces 32, 34.

Pour chaque corne 82 interposée entre le pied 78 du T dudit séparateur 76 et le pied 78 du T d'un autre séparateur 76, cette extrémité libre 84 est disposée longitudinalement sensiblement aux deux-tiers de la distance entre lesdits pieds 78. Pour chaque corne 82 interposée entre le pied 78 du T dudit séparateur 76 et l'une des plaques d'extrémité longitudinale 60, sans autre séparateur 76 interposé entre ladite corne 82 et ladite paroi 60, l'extrémité libre 84 est disposée longitudinalement sensiblement aux deux-tiers de la distance entre le pied 78 du T dudit séparateur 76 et le point du premier tronçon 62 le plus éloigné dudit pied 78.For each horn 82 interposed between the foot 78 of the T of said separator 76 and the foot 78 of the T of another separator 76, this free end 84 is disposed longitudinally substantially two-thirds of the distance between said feet 78. For each horn 82 interposed between the foot 78 of the T of said separator 76 and one of the longitudinal end plates 60, without other separator 76 interposed between said horn 82 and said wall 60, the free end 84 is disposed longitudinally substantially two-thirds the distance between the foot 78 of the T of said separator 76 and the point of the first section 62 furthest from said foot 78.

Le point de rebroussement 66 de chaque plaque d'extrémité longitudinale 60 est par ailleurs disposé longitudinalement sensiblement aux deux-tiers de la distance entre le pied 78 du T du séparateur 76 le plus proche de ladite plaque 60 et le point du premier tronçon 62 le plus éloigné dudit pied 78.The cusp 66 of each longitudinal end plate 60 is also disposed longitudinally substantially two-thirds of the distance between the foot 78 of the T of the separator 76 closest to said plate 60 and the point of the first section 62. further away from said foot 78.

Ainsi, la section principale de chaque conduit 70 présente une forme méandreuse, c'est-à-dire que la sinuosité de ladite section principale est supérieure à 1,50.Thus, the main section of each duct 70 has a meandering shape, that is to say that the sinuosity of said main section is greater than 1.50.

Dans l'exemple représenté, un évidement 86 est ménagé dans chaque corne 82 de chaque séparateur 76 dont le pied 78 est orienté vers la première face 32. Cet évidement 86 est traversant et débouche dans l'extrémité libre 84. Il présente une hauteur, prise selon une direction perpendiculaire à la plaque 54, maximale au niveau de l'extrémité libre 84, ladite hauteur allant décroissante depuis l'extrémité libre 84 jusqu'à la barre 80 du T. Cet évidement 86 est en particulier sensiblement en forme de demi-disque.In the example shown, a recess 86 is formed in each horn 82 of each separator 76 whose foot 78 is oriented towards the first face 32. This recess 86 is through and opens into the free end 84. It has a height, taken in a direction perpendicular to the plate 54, maximum at the free end 84, said height decreasing from the free end 84 to the bar 80 of T. This recess 86 is in particular substantially shaped half -disk.

Cet évidement 86 permet d'augmenter le drainage vers l'extérieur de l'eau captée par les parois du conduit 70.This recess 86 makes it possible to increase the drainage towards the outside of the water captured by the walls of the duct 70.

En référence à la Figure 5, chaque conduit 70 présente également une section transversale, prise selon un plan transversal, de hauteur décroissante depuis la première face latérale 32 jusqu'à la deuxième face latérale 34, ladite hauteur étant mesurée selon une direction perpendiculaire à la plaque 54.With reference to the Figure 5 each duct 70 also has a cross section, taken along a transverse plane, decreasing in height from the first lateral face 32 to the second lateral face 34, said height being measured in a direction perpendicular to the plate 54.

Toujours en référence à la Figure 5, le boîtier d'aération 30 comprend également un dispositif d'encliquetage 90 pour l'encliquetage du boîtier 30 à un contour de la fente 28 dans laquelle il est logé.Still referring to the Figure 5 , the ventilation housing 30 also comprises a detent device 90 for snapping the housing 30 to a contour of the slot 28 in which it is housed.

Ce dispositif d'encliquetage 90 comprend des premières lamelles 92 formées dans la plaque 58 et des deuxièmes lamelles 94 formées dans une nervure 96 faisant saillie transversalement depuis le cadre 36 en direction de la deuxième face latérale 34, ladite nervure 96 étant disposée en-dessous de la plaque 54.This latching device 90 comprises first slats 92 formed in the plate 58 and second slats 94 formed in a rib 96 projecting transversely from the frame 36 towards the second lateral face 34, said rib 96 being disposed below. of the plate 54.

Chacune desdites lamelles, respectivement 92, 94, comprend une base 98 solidaire du reste de la plaque 58, respectivement du reste de la nervure 96, et une extrémité libre 100 opposée, l'extrémité libre 100 étant plus proche du cadre 36 que la base 98. Chaque lamelle 92, 94 s'étend sensiblement transversalement depuis sa base 98 jusqu'à son extrémité libre 100.Each of said strips, respectively 92, 94, comprises a base 98 integral with the remainder of the plate 58, respectively of the remainder of the rib 96, and an opposite free end 100, the free end 100 being closer to the frame 36 than the base 98. Each lamella 92, 94 extends substantially transversely from its base 98 to its free end 100.

La base 98 forme une articulation de pivotement de la lamelle, respectivement 92, 94, relativement au reste de la plaque 58, respectivement relativement au reste de la nervure 96, autour d'un axe de rotation longitudinal.The base 98 forms a hinge pivoting of the blade, respectively 92, 94, relative to the remainder of the plate 58, respectively relative to the remainder of the rib 96, about a longitudinal axis of rotation.

L'extrémité libre 100 porte un ergot 104 faisant saillie relativement au reste de la plaque 58, respectivement relativement au reste de la nervure 96, à l'opposé de l'espace de circulation d'air 68. Lorsque la lamelle 92, 94 est au repos, cet ergot 104 est à une distance du cadre 36 sensiblement égale à l'épaisseur du contour de la fente 28, de préférence légèrement inférieure à ladite épaisseur. L'ergot 104 présente une première face 106 en regard du cadre 36, ladite face 106 étant sensiblement parallèle à ladite face 36. L'ergot 104 présente également une deuxième face 108 biseautée opposée au cadre 36.The free end 100 carries a lug 104 protruding from the remainder of the plate 58, respectively relative to the remainder of the rib 96, opposite the air circulation space 68. When the plate 92, 94 is at rest, this lug 104 is at a distance from the frame 36 substantially equal to the thickness of the contour of the slot 28, preferably slightly less than said thickness. The lug 104 has a first face 106 facing the frame 36, said face 106 being substantially parallel to said face 36. The lug 104 also has a second beveled face 108 opposite to the frame 36.

Chaque lamelle 92, 94 porte également une manette 110 faisant saillie relativement au reste de la plaque 58, respectivement relativement au reste de la nervure 96, en direction de l'espace de circulation d'air 68 et vers la deuxième face latérale 34. Cette manette 110 permet à un utilisateur d'agir sur la lamelle 92, 94 de manière à rétracter l'ergot 104 vers l'intérieur de l'espace de circulation d'air 68.Each strip 92, 94 also carries a lever 110 protruding relative to the rest of the plate 58, respectively relative to the remainder of the rib 96, in the direction of the air circulation space 68 and towards the second lateral face 34. The lever 110 allows a user to act on the slide 92, 94 so as to retract the lug 104 inwardly of the air flow space 68.
