Description

DOMAINE TECHNIQUETECHNICAL AREA

L'invention s'inscrit dans le domaine des accessoires de matériels ferroviaires roulants.The invention falls within the field of accessories for railway rolling stock.

L'invention porte plus particulièrement sur une baie de fenêtre et sur un matériel ferroviaire roulant comprenant une telle baie de fenêtre.The invention relates more particularly to a window opening and to railway rolling stock comprising such a window opening.

ART ANTERIEUR ET INCONVENIENTS DE L'ART ANTERIEURPRIOR ART AND DRAWBACKS OF PRIOR ART

Dans la plupart des matériels ferroviaires roulants, et en particulier dans les véhicules ferroviaires destinés à transporter des voyageurs, les fenêtres sont la plupart du temps équipées de stores à enroulement autour d'un arbre dont l'axe est parallèle à l'axe longitudinal du véhicule. Ces stores sont actionnables manuellement et mobiles de bas en haut entre une position d'obturation de la fenêtre et une position de dégagement de la fenêtre.In most railway rolling stock, and in particular in railway vehicles intended to transport passengers, the windows are usually fitted with roller blinds around a shaft whose axis is parallel to the longitudinal axis of the vehicle. These blinds are manually operable and movable from bottom to top between a closed position of the window and a release position of the window.

Cependant, les fenêtres équipant ces véhicules ferroviaires s'étendent la plupart du temps au niveau d'au moins deux sièges passagers. Ainsi, un passager désirant abaisser le store bouchera la vue au passager voisin dont le siège est également en vis-à-vis de la fenêtre. Cette situation peut être source de conflit entre les voyageurs.However, the windows fitted to these railway vehicles most of the time extend to the level of at least two passenger seats. Thus, a passenger wishing to lower the blind will obstruct the view of the neighboring passenger whose seat is also opposite the window. This situation can be a source of conflict between travelers.

En outre, les systèmes d'enroulements des stores sont complexes à mettre en œuvre et sont fragiles. Un système d'enroulement défectueux risque ainsi de provoquer l'enroulement brusque du store vers sa position de dégagement. Enfin, le matériau composant le store nécessite une tenue mécanique spécifique à l'enroulement autour de l'arbre, tout en respectant les différentes normes de sécurité imposées. La fabrication des stores est donc couteuse, et l'offre pour les matériaux composant ces stores est particulièrement limitée.In addition, blind winding systems are complex to implement and are fragile. A faulty winding system thus risks causing the blind to roll up suddenly towards its release position. Finally, the material making up the awning requires a specific mechanical resistance to the winding around the shaft, while respecting the various imposed safety standards. The manufacture of blinds is therefore expensive, and the supply of the materials making up these blinds is particularly limited.

Le document FR 3 067 293 A1 décrit une baie de fenêtre d'un matériel, comportant une ouverture encadrée par des bords d'encadrement et qui s'étend selon un axe longitudinal définissant sa largeur et au moins un axe transversal définissant sa hauteur, laquelle baie comporte au moins un volet d'occultation relié à au moins l'un des bords de ladite baie par des moyens de liaison, où en ce qu'elle comprend des moyens de variation de l'intensité lumineuse d'au moins une portion d'interaction visuelle de l'ouverture destinée à être en vis-à-vis d'un usager, configurés pour faire passer le volet au moins depuis une position de dégagement de la hauteur de ladite portion d'interaction visuelle de l'ouverture, à une position d'occultation au moins partielle de ladite portion d'interaction visuelle.The document FR 3 067 293 A1 describes a window opening of a material, comprising an opening framed by framing edges and which extends along a longitudinal axis defining its width and at least one transverse axis defining its height, which opening comprises at least one shutter concealment connected to at least one of the edges of said bay by connecting means, or in that it comprises means for varying the light intensity of at least a visual interaction portion of the opening intended to face a user, configured to cause the shutter to pass at least from a position clear of the height of said visual interaction portion of the opening, to a position of concealment at least partial of said visual interaction portion.

OBJECTIF DE L'INVENTIONOBJECTIVE OF THE INVENTION

L'invention vise donc à proposer un baie de fenêtre d'un matériel ferroviaire roulant simple et peu couteuse à mettre en œuvre, et limitant les situations de conflit entre voyageurs.The invention therefore aims to provide a window opening of a material simple and inexpensive to implement, and limiting conflict situations between passengers.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Il est tout d'abord précisé que sur les figures, les mêmes références désignent les mêmes éléments quelle que soit la figure sur laquelle elles apparaissent et quelle que soit la forme de représentation de ces éléments. De même, si des éléments ne sont pas spécifiquement référencés sur l'une des figures, leurs références peuvent être aisément retrouvées en se reportant à une autre figure.It is first of all specified that in the figures, the same references designate the same elements regardless of the figure in which they appear and regardless of the form of representation of these elements. Similarly, if elements are not specifically referenced in one of the figures, their references can easily be found by referring to another figure.

Il est également précisé que les figures représentent essentiellement trois modes de réalisation de l'objet de l'invention mais qu'il peut exister d'autres modes de réalisation qui répondent à la définition de l'invention.It is also specified that the figures essentially represent three embodiments of the subject of the invention but that there may be other embodiments which correspond to the definition of the invention.

La baie de fenêtre 1a, 1b, 1c qui va être décrite ci-après concerne une baie de fenêtre d'un matériel ferroviaire roulant, mais il est entendu que cette baie de fenêtre 1a, 1b, 1c peut s'appliquer à tout type de matériel fixe ou roulant, ou de façade.The window bay 1a, 1b, 1c which will be described below relates to a window bay of railway rolling stock, but it is understood that this bay of window 1a, 1b, 1c can be applied to any type of fixed or rolling equipment, or facade.

Le matériel ferroviaire roulant comprend au moins une voiture motrice de tête, et une pluralité de voitures reliées entre-elles. Alternativement, le matériel ferroviaire roulant est un unique véhicule avec un poste de conduite à chaque extrémité et une salle centrale. Un tel matériel ferroviaire roulant peut être un train de voyageurs, dont les voitures comprennent des baies de fenêtres vitrées 1a, 1b, 1c pour permettre aux usagers de regarder le paysage.The railway rolling stock comprises at least one lead motor car, and a plurality of cars connected to each other. Alternatively, rolling stock is a single vehicle with a driving position at each end and a central room. Such railway rolling stock can be a passenger train, the cars of which include bay windows 1a, 1b, 1c to allow users to watch the landscape.

La baie de fenêtre 1a - 1c comprend une ouverture 2 encadrée par des bords d'encadrement 3, 4, 5, 6. Typiquement, l'ouverture 2 présente une surface globalement rectangulaire avec le cas échéant des bords arrondis. Cette ouverture 2 s'étend selon un axe longitudinal X définissant sa largeur, et selon au moins un axe transversal Y définissant sa hauteur.The window opening 1a - 1c comprises an opening 2 framed by framing edges 3, 4, 5, 6. Typically, the opening 2 has a generally rectangular surface with, where appropriate, rounded edges. This opening 2 extends along a longitudinal axis X defining its width, and along at least one transverse axis Y defining its height.

Avantageusement, mais de manière non limitative, l'ouverture est fermée par une vitre encadrée par les bords d'encadrement 3, 4, 5, 6 et qui, de manière connue, peut comporter des motifs 27, ou bien avoir reçu un traitement isolant thermique. La vitre s'étend donc selon l'axe longitudinal X définissant sa largeur, et selon au moins l'axe transversal Y définissant sa hauteur.Advantageously, but in a non-limiting manner, the opening is closed by a window framed by the framing edges 3, 4, 5, 6 and which, in a known manner, may comprise patterns 27, or else have received an insulating treatment. thermal. The window therefore extends along the longitudinal axis X defining its width, and along at least the transverse axis Y defining its height.

La baie de fenêtre 1a - 1c comprend au moins un volet d'occultation 7, 7', 8, 8', 9, 9', 10, 10' relié par des moyens de liaison à au moins l'un des bords 3, 4 de ladite baie de fenêtre 1a - 1c. Le volet 7, 7', 8, 8', 9, 9', 10, 10' peut être réalisé dans un matériau rigide, par exemple un matériau plastique, ou bien dans un matériau souple, par exemple un matériau textile. Préférentiellement, chaque volet 7, 7', 8, 8', 9, 9', 10, 10' est relié respectivement au bord supérieur 3 et au bord inférieur 4 de la baie de fenêtre 1a - 1c. Les bords supérieur 3 et inférieur 4 sont en vis-à-vis et s'étendent parallèlement à l'axe longitudinal X de l'ouverture 2. En outre, les termes « supérieur » et « inférieur » sont à comprendre relativement au(x) usager(s) assis à proximité de la baie de fenêtre 1a - 1c, le bord supérieur 3 étant ainsi, pour l'usager, plus haut que le bord inférieur 4.The window opening 1a - 1c comprises at least one shutter 7, 7', 8, 8', 9, 9', 10, 10' connected by connecting means to at least one of the edges 3, 4 of said window opening 1a - 1c. The flap 7, 7', 8, 8', 9, 9', 10, 10' can be made of a rigid material, for example a plastic material, or else of a flexible material, for example a textile material. Preferably, each flap 7, 7', 8, 8', 9, 9', 10, 10' is respectively connected to the upper edge 3 and to the lower edge 4 of the window opening 1a - 1c. The upper 3 and lower 4 edges face each other and extend parallel to the longitudinal axis X of the opening 2. In addition, the terms “upper” and “lower” are to be understood relative to the(x ) user(s) seated near the window opening 1a - 1c, the upper edge 3 thus being, for the user, higher than the lower edge 4.

Selon l'invention, la baie de fenêtre 1a - 1c comprend des moyens de variation de l'intensité lumineuse 11a, 11b, 11c d'au moins une portion d'interaction visuelle 12, 12' de l'ouverture 2 destinée à être en vis-à-vis d'un usager, ces moyens étant configurés pour faire passer le volet 7, 7', 8, 8', 9, 9', 10, 10' au moins depuis une position de dégagement de la hauteur de ladite portion d'interaction visuelle 12, 12' de l'ouverture 2, à une position d'occultation au moins partielle de ladite portion d'interaction visuelle 12, 12' de l'ouverture 2.According to the invention, the window opening 1a - 1c comprises means 11a, 11b, 11c for varying the light intensity of at least one visual interaction portion 12, 12' of the opening 2 intended to be in vis-à-vis a user, these means being configured to cause the flap 7, 7', 8, 8', 9, 9', 10, 10' to pass at least from a position clearing the height of said visual interaction portion 12, 12' of opening 2, at a position at least partially concealing said visual interaction portion 12, 12' of opening 2.

La portion d'interaction visuelle 12, 12' de l'ouverture 2, dont deux sont représentées respectivement sur les figures 1 à 3 et 5, est la portion de l'ouverture 2 à travers laquelle un usager peut regarder, par exemple pour observer le paysage. En particulier, la portion d'interaction visuelle ne représente pas nécessairement l'intégralité de la portion d'ouverture en regard du passager, mais cette portion d'interaction visuelle définit une portion d'ouverture à travers laquelle le passager peut voir au moins en partie, par exemple vers l'extérieur. Pour éviter les conflits entre deux usagers qui partagent la même ouverture 2, il est important que chaque usager puisse contrôler de manière indépendante l'occultation de la portion d'ouverture 2 qui est directement en regard dudit usager, car s'est en dégageant cette portion d'ouverture 2 que l'usager pourra par exemple observer le paysage, et c'est en occultant cette portion d'ouverture 2 que l'usager pourra, par exemple, se protéger du soleil.The visual interaction portion 12, 12' of the opening 2, two of which are represented respectively on the figures 1 to 3 and 5 , is the portion of the opening 2 through which a user can look, for example to observe the landscape. In particular, the visual interaction portion does not necessarily represent the entire portion of the opening facing the passenger, but this visual interaction portion defines an opening portion through which the passenger can see at least part, for example outwards. To avoid conflicts between two users who share the same opening 2, it is important that each user can independently control the concealment of the portion of opening 2 which is directly opposite said user, because by releasing this opening portion 2 that the user can for example observe the landscape, and it is by concealing this opening portion 2 that the user can, for example, protect himself from the sun.

Ainsi, si une ouverture 2 s'étend sur deux sièges passagers, cette dernière comporte deux portions d'interaction visuelle 12, 12' associées aux deux usagers respectifs.Thus, if an opening 2 extends over two passenger seats, the latter comprises two visual interaction portions 12, 12' associated with the two respective users.

Selon l'invention, chaque usager peut donc choisir d'occulter ou de dégager la portion d'interaction visuelle 12, 12' associée, sans agir sur l'occultation ou le dégagement de la portion d'interaction visuelle 12, 12' associée à l'usager voisin, en agissant sur les moyens de variations d'intensité lumineuse 11a - 11c qui seront décrits en détail ci-après.According to the invention, each user can therefore choose to conceal or clear the associated visual interaction portion 12, 12', without acting on the concealment or clearing of the visual interaction portion 12, 12' associated with the neighboring user, by acting on the light intensity variation means 11a - 11c which will be described in detail below.

Selon un premier mode de réalisation de l'invention en référence à la figure 1, la baie de fenêtre 1a comprend un volet 7, 7' pour chaque portion d'interaction visuelle 12, 12' associée à l'usager considéré.According to a first embodiment of the invention with reference to the figure 1 , the window opening 1a comprises a flap 7, 7' for each visual interaction portion 12, 12' associated with the user in question.

La baie de fenêtre 1a comprend en outre deux rails respectivement supérieur 13 et inférieur 14 montés en regard l'un de l'autre sur les bords respectivement supérieur 3 et inférieur 4 de la baie 1a. Comme représenté sur la figure 1, la longueur des rails 13, 14 et la largeur de l'ouverture 2 sont identiques, si bien que les extrémités opposées des rails ne débordent pas de la baie de fenêtre 1a. De manière alternative, comme représenté sur la figure 2, les rails présentent une longueur supérieure à la largeur de l'ouverture 2 et s'étendent donc au-delà des bords latéraux 5, 6 de la baie de fenêtre 1b.The window opening 1a further comprises two respectively upper 13 and lower 14 rails mounted opposite one another on the respectively upper 3 and lower 4 edges of the opening 1a. As shown on the figure 1 , the length of the rails 13, 14 and the width of the opening 2 are identical, so that the opposite ends of the rails do not project beyond the window opening 1a. Alternatively, as shown in the picture 2 , the rails have a length greater than the width of the opening 2 and therefore extend beyond the side edges 5, 6 of the window opening 1b.

Chaque volet 7, 7' est relié aux bords supérieur 3 et inférieur 4 de la baie 1a par l'intermédiaire d'un axe de guidage 15, 15' sur lequel ledit volet 7, 7' est monté : les extrémités opposés 17, 18 ; 17', 18' de l'axe de guidage 15, 15' du volet considéré 7, 7' coopèrent avec les deux rails respectifs 13, 14. Plus précisément, cet axe de guidage 15 s'étend parallèlement à l'axe transversal Y de l'ouverture 2 et comprend deux bouts d'arbres 150, 151; 150', 151' solidaires des extrémités opposées supérieure 70, 70' et inférieure 71, 71' du volet 7, 7', et passant par l'axe longitudinal Z, Z' du volet 7, 7'. L'extrémité 17, 17' du bout d'arbre supérieur 150, 150' coopère à translation avec le rail supérieur 13, tandis que l'extrémité 18, 18' du bout d'arbre inférieur 151, 151' coopère à translation avec le rail inférieur 14. L'axe de guidage 15, 15' et les rails 13, 14 forment les moyens de variation de l'intensité lumineuse 11a dans le premier mode de réalisation de l'invention.Each flap 7, 7' is connected to the upper 3 and lower 4 edges of the opening 1a via a guide pin 15, 15' on which said flap 7, 7' is mounted: the opposite ends 17, 18 ; 17', 18' of the guide pin 15, 15' of the considered flap 7, 7' cooperate with the two respective rails 13, 14. More precisely, this guide pin 15 extends parallel to the transverse axis Y of the opening 2 and comprises two shaft ends 150, 151; 150', 151' integral with the upper 70, 70' and lower 71, 71' opposite ends of the flap 7, 7', and passing through the longitudinal axis Z, Z' of the flap 7, 7'. The end 17, 17' of the upper shaft end 150, 150' cooperates in translation with the upper rail 13, while the end 18, 18' of the lower shaft end 151, 151' cooperates in translation with the lower rail 14. The guide pin 15, 15' and the rails 13, 14 form the light intensity variation means 11a in the first embodiment of the invention.

Selon une première variante, les extrémités des bouts d'arbres 17, 17', 18, 18' sont aplaties pour pouvoir coulisser chacune dans une rainure longitudinale 140, 210, 220 du rail considéré 14, 21, 22 (voir figures 4, 6a et 6b). Selon une seconde variante, les extrémités des bouts d'arbres 17, 17', 18, 18' comprennent des patins ou des roulettes 28 (voir figure 3) pour coopérer à translation avec les rails considérés 21, 22.According to a first variant, the ends of the ends of shafts 17, 17', 18, 18' are flattened in order to be able to slide each in a longitudinal groove 140, 210, 220 of the considered rail 14, 21, 22 (see figure 4 , 6a and 6b ). According to a second variant, the ends of the shaft ends 17, 17', 18, 18' comprise pads or rollers 28 (see figure 3 ) to cooperate in translation with the considered rails 21, 22.

L'usager peut ainsi faire translater le volet considéré 7, 7' entre ses positions de dégagement et d'occultation partielle de la portion d'interaction visuelle associée 12, 12', lequel volet 7, 7' s'étend sur toute la hauteur de l'ouverture 2, quelle que soit sa position. En outre, afin de ne pas interagir avec la portion d'interaction visuelle 12, 12' associée à l'autre usager, la largeur du volet 7, 7', c'est-à-dire sa dimension selon une direction parallèle à l'axe longitudinal X de l'ouverture 2, est inférieure ou égale, préférentiellement inférieure, à la largeur de l'ouverture 2. De manière avantageuse, chaque rail 13, 14 peut également comprendre une butée (non représentée sur la figure 1) située au voisinage du milieu dudit rail 13, 14, et qui bloque le déplacement du volet 7, 7' au-delà de cette butée. Le mouvement de chaque volet 7, 7' est donc confiné entre le bord latéral considéré 5, 6 de la baie de fenêtre 1 et les butées.The user can thus translate the relevant flap 7, 7' between its positions of release and partial concealment of the associated visual interaction portion 12, 12', which flap 7, 7' extends over the entire height of opening 2, whatever its position. In addition, in order not to interact with the visual interaction portion 12, 12' associated with the other user, the width of the flap 7, 7', that is to say its dimension in a direction parallel to the longitudinal axis X of the opening 2, is less than or equal to, preferably less than, the width of the opening 2. Advantageously, each rail 13, 14 can also include a stop (not shown on the figure 1 ) located in the vicinity of the middle of said rail 13, 14, and which blocks the movement of the flap 7, 7 'beyond this stop. The movement of each flap 7, 7' is therefore confined between the considered side edge 5, 6 of the window opening 1 and the stops.

Selon un deuxième mode de réalisation de l'invention en référence aux figure 2 à 4, la baie de fenêtre 1b comprend des premier 7, 7' et second 8, 8' volets pour chaque portion d'interaction visuelle 12, 12' associée à l'usager considéré. Sur la figure 2, les volets 7' et 8' sont dans leur position d'obturation de la portion d'interaction visuelle 12', tandis que les volets 7 et 8 sont dans une position intermédiaire entre la position de dégagement et la position d'obturation de la portion d'interaction visuelle 12.According to a second embodiment of the invention with reference to the figure 2 to 4 , the window opening 1b comprises first 7, 7' and second 8, 8' flaps for each visual interaction portion 12, 12' associated with the user in question. On the picture 2 , the flaps 7' and 8' are in their position for closing off the portion visual interaction 12 ', while the flaps 7 and 8 are in an intermediate position between the release position and the closed position of the visual interaction portion 12.

La baie de fenêtre 1b comprend deux paires de rails respectivement supérieure 19 et inférieure 20 montées en regard l'une de l'autre sur les bords respectivement supérieur 3 et inférieur 4 de la baie 1b. En outre, chaque paire de rails 19, 20 comprend des premier 21 et second 22 rails, disposés de telle sorte que les premiers rails 21 des paires de rails respectives 19, 20 sont en regard, et que les seconds rails 22 des paires de rails respectives 19, 20 sont également en regard. Enfin, les rails 21, 22 de chaque paire de rails 19, 20 sont parallèles.The window opening 1b comprises two pairs of respectively upper 19 and lower 20 rails mounted facing each other on the respectively upper 3 and lower 4 edges of the opening 1b. In addition, each pair of rails 19, 20 comprises first 21 and second 22 rails, arranged such that the first rails 21 of the respective pairs of rails 19, 20 are opposite, and that the second rails 22 of the pairs of rails respective 19, 20 are also opposite. Finally, the rails 21, 22 of each pair of rails 19, 20 are parallel.

Dans ce deuxième mode de réalisation et à l'instar du premier mode de réalisation, chaque volet 7, 7', 8, 8' est relié aux bords supérieur 3 et inférieur 4 de la baie 1b par l'intermédiaire d'un axe de guidage 15, 15', 16, 16' sur lequel ledit volet 7, 7', 8, 8' est monté, l'axe de guidage 15, 15', 16, 16' de chaque volet 7, 7', 8, 8' étant formé par deux bouts d'arbres 150, 150', 151, 151', 160, 160', 161, 161' tels que décrits ci-dessus. Plus précisément, les extrémités opposées 150, 150'; 151, 151' de l'axe de guidage 15, 15' du premier volet 7, 7' coopèrent à translation avec les premiers rails 21 en vis-à-vis des paires de rails supérieure 19 et inférieure 20, tandis que les extrémités opposées 160, 160', 161, 161' de l'axe de guidage 16, 16' du second volet 8, 8' coopèrent à translation avec les seconds rails 22 en vis-à-vis des paires de rails supérieure 19 et inférieure 20. Les deux axes de guidage 15, 15', 23, 23' et les deux paires de rails 19, 20 forment les moyens de variation de l'intensité lumineuse 11b dans le deuxième mode de réalisation de l'invention.In this second embodiment and like the first embodiment, each flap 7, 7', 8, 8' is connected to the upper 3 and lower 4 edges of the bay 1b via an axis of guide 15, 15', 16, 16' on which said flap 7, 7', 8, 8' is mounted, the guide pin 15, 15', 16, 16' of each flap 7, 7', 8, 8' being formed by two shaft ends 150, 150', 151, 151', 160, 160', 161, 161' as described above. Specifically, opposite ends 150, 150'; 151, 151' of the guide pin 15, 15' of the first flap 7, 7' cooperate in translation with the first rails 21 facing the pairs of upper 19 and lower 20 rails, while the opposite ends 160, 160', 161, 161' of the guide pin 16, 16' of the second flap 8, 8' cooperate in translation with the second rails 22 facing the pairs of upper 19 and lower 20 rails. The two guide pins 15, 15', 23, 23' and the two pairs of rails 19, 20 form the light intensity variation means 11b in the second embodiment of the invention.

L'usager peut ainsi faire translater les deux volets 7, 7', 8, 8' entre leurs positions de dégagement et d'occultation partielle de la portion d'interaction visuelle associée 12, 12', lequel volet 7, 7', 8, 8' s'étend sur toute la hauteur de l'ouverture 2, quelle que soit la position dudit volet 7, 7', 8, 8'. En particulier, grâce à la présence des deux volets 7, 7', 8, 8', l'usager peut faire varier à sa guise la surface occupée par les deux volets 7, 7', 8, 8' disposés en position d'occultation partielle de la portion d'interaction visuelle associée 12, 12'. Cette surface d'occultation peut être diminuée lorsque les deux volets 7, 8; 7', 8' sont en partie superposés (partie gauche des figures 2 et 3) ou augmentée lorsque les deux volets ne sont pas superposés (partie droite des figures 2 et 3).The user can thus translate the two flaps 7, 7', 8, 8' between their positions of release and partial concealment of the associated visual interaction portion 12, 12', which flap 7, 7', 8 , 8' extends over the entire height of the opening 2, regardless of the position of said flap 7, 7', 8, 8'. In particular, thanks to the presence of the two flaps 7, 7', 8, 8', the user can vary the surface occupied by the two flaps 7, 7', 8, 8' arranged in the position of partial concealment of the associated visual interaction portion 12, 12'. This concealment surface can be reduced when the two flaps 7, 8; 7', 8' are partially superimposed (left part of the figure 2 and 3 ) or increased when the two panes are not superimposed (right part of the figure 2 and 3 ).

En outre, afin de ne pas interagir avec la portion d'interaction visuelle 12, 12' associée à l'autre usager, la largeur du volet 7, 7', 8, 8', c'est-à-dire sa dimension selon une direction parallèle à l'axe longitudinal X de l'ouverture 2, est inférieure ou égale, préférentiellement inférieure, à la demi-largeur de l'ouverture 2. De manière avantageuse, chaque rail 21, 22 peut également comprendre une butée 29 située au voisinage du milieu dudit rail 21, 22, et qui bloque le déplacement du volet considéré 7, 7', 8, 8' au-delà de cette butée 29. Le mouvement de chaque volet 7, 7', 8, 8' est donc confiné entre le bord latéral considéré 5, 6 de la baie de fenêtre 1b et les butées 29.Furthermore, in order not to interact with the visual interaction portion 12, 12' associated with the other user, the width of the flap 7, 7', 8, 8', that is to say its dimension according to a direction parallel to the longitudinal axis X of the opening 2, is less than or equal to, preferably less than, the half-width of the opening 2. Advantageously, each rail 21, 22 can also comprise an abutment 29 located in the vicinity of the middle of said rail 21, 22, and which blocks the movement of the considered flap 7, 7', 8, 8' beyond this stop 29. The movement of each flap 7, 7', 8, 8' is therefore confined between the considered side edge 5, 6 of the window opening 1b and the stops 29.

Selon une variante de réalisation non représentée, chaque volet monté sur la baie 1a, 1b selon le premier ou le deuxième mode de réalisation est du type accordéon. Il est ainsi configurable entre une position pliée et une position déployée. En outre, la direction de déploiement et de repliement est perpendiculaire à l'axe longitudinal X de l'ouverture 2. Le volet accordéon présente ainsi une largeur variable et réglable par l'usager. Un tel volet accordéon permet à l'usager de modifier la surface de la portion occultée par ledit volet sans qu'il ne soit nécessaire de translater ou de faire pivoter ce dernier.According to a variant embodiment not shown, each shutter mounted on the bay 1a, 1b according to the first or the second embodiment is of the accordion type. It is thus configurable between a folded position and an extended position. In addition, the deployment and folding direction is perpendicular to the longitudinal axis X of the opening 2. The accordion flap thus has a variable width that can be adjusted by the user. Such an accordion flap allows the user to modify the surface of the portion obscured by said flap without it being necessary to translate or rotate the latter.

Selon un troisième mode de réalisation de l'invention en référence aux figures 5, 6a et 6b, la baie de fenêtre 1c comprend au moins un volet 9, 9', préférentiellement deux volets 9, 10; 9', 10' pour chaque portion d'interaction visuelle 12, 12' associée à l'usager considéré.According to a third embodiment of the invention with reference to the figures 5, 6a and 6b , the window opening 1c comprises at least one flap 9, 9', preferably two flaps 9, 10; 9', 10' for each visual interaction portion 12, 12' associated with the user in question.

A l'instar du premier mode de réalisation, la baie de fenêtre 1c comprend deux rails respectivement supérieur 13 et inférieur 14 monté en regard l'un de l'autre sur les bords respectivement supérieur 3 et inférieur 4 de la baie. Comme représenté sur la figure 5, la longueur des rails 13, 14 et la largeur de l'ouverture 2 sont identiques, si bien que les extrémités opposées des rails ne débordent pas de la baie de fenêtre 1c. De manière alternative, comme représenté sur la figure 2, les rails 13, 14 sont plus grands que la largeur de l'ouverture 2 et dépassent donc de part et d'autre des bords latéraux 5, 6 de la baie de fenêtre 1c.Like the first embodiment, the window opening 1c comprises two respectively upper 13 and lower 14 rails mounted facing each other on the respectively upper 3 and lower 4 edges of the opening. As shown on the figure 5 , the length of the rails 13, 14 and the width of the opening 2 are identical, so that the opposite ends of the rails do not project beyond the window opening 1c. Alternatively, as shown in the picture 2 , the rails 13, 14 are larger than the width of the opening 2 and therefore protrude on either side of the side edges 5, 6 of the window opening 1c.

Chaque volet 9, 10 ; 9', 10' est relié aux bords supérieur 3 et inférieur 4 de la baie par l'intermédiaire de son axe de guidage 23, 24 ; 23', 24' sur lequel ledit volet 9, 10; 9', 10' est monté : les extrémités opposés 25, 26 ;25', 26' de l'axe de guidage 23, 24 ; 23', 24' du volet considéré 9, 10; 9', 10' coopèrent avec les deux rails respectifs 13, 14.Each flap 9, 10; 9', 10' is connected to the upper 3 and lower 4 edges of the opening via its guide pin 23, 24; 23', 24' on which said flap 9, 10; 9', 10' is mounted: the opposite ends 25, 26; 25', 26' of the guide pin 23, 24; 23', 24' of the considered flap 9, 10; 9', 10' cooperate with the two respective rails 13, 14.

Dans ce troisième mode de réalisation, l'axe de guidage 23, 23', 24, 24' du volet 9, 9', 10, 10' est formé d'une tige cylindrique, lequel volet 9, 9', 10, 10' est monté à pivotement autour de cette tige cylindrique 23, 23', 24, 24'. En référence aux figures 5, 6a et 6b, le volet 9, 9', 10, 10' comprend au niveau de l'un de ses bords un fourreau 30, 30', 31, 31' dans lequel la tige 23, 23', 24, 24' est emmanchée, mais tout autre type de moyen de liaison à pivotement connu entre la tige et le volet est possible, notamment des charnières.In this third embodiment, the guide pin 23, 23', 24, 24' of the flap 9, 9', 10, 10' is formed by a cylindrical rod, which flap 9, 9', 10, 10 'is pivotally mounted around this cylindrical rod 23, 23', 24, 24'. With reference to figures 5, 6a and 6b , the flap 9, 9', 10, 10' comprises at one of its edges a sheath 30, 30', 31, 31' in which the rod 23, 23', 24, 24' is fitted, but any other type of known pivoting connection means between the rod and the flap is possible, in particular hinges.

Les deux extrémités opposées 25, 26; 25', 26' de la tige 23, 24 ; 23', 24' débordent du volet 9, 10 ; 9', 10' pour coopérer à translation avec les rails considérés 13, 14, comme cela est représenté sur les figures 6a et 6b. La structure des extrémités opposées de la tige est telle que décrit précédemment, en lien avec les premier et second modes de réalisation de la baie 1a, 1b. La tige de guidage 23, 24, 23', 24' et les rails 13, 14 forment les moyens de variation de l'intensité lumineuse 11c dans le troisième mode de réalisation de l'invention.The two opposite ends 25, 26; 25', 26' rod 23, 24; 23', 24' overflow from the flap 9, 10; 9 ', 10' to cooperate in translation with the considered rails 13, 14, as shown in the figures 6a and 6b . The structure of the opposite ends of the rod is as described above, in connection with the first and second embodiments of the bay 1a, 1b. The guide rod 23, 24, 23', 24' and the rails 13, 14 form the light intensity variation means 11c in the third embodiment of the invention.

Dans ce troisième mode de réalisation, les volets 9, 10, 9', 10' sont mobiles à translation tels que décrit précédemment, et également à pivotement entre une position de dégagement dans laquelle chaque volet 9, 10, 9', 10' s'étend dans un plan perpendiculaire à l'ouverture 2 (voir figure 6a), et une position d'obturation au moins partielle de la portion d'interaction visuelle 12, 12' associée dans laquelle les volets 9, 10, 9', 10' s'étendent dans un plan parallèle à l'ouverture (voir figure 6b). En outre, les volets 9, 10, 9', 10' pouvant pivoter selon une amplitude de 180°, ces derniers peuvent s'étendre parallèlement à l'ouverture 2 de part et d'autre de la tige de guidage 23, 23', 24, 24'.In this third embodiment, the flaps 9, 10, 9', 10' are movable in translation as described previously, and also in pivoting between a release position in which each flap 9, 10, 9', 10' s extends in a plane perpendicular to opening 2 (see figure 6a ), and a position of at least partial closure of the associated visual interaction portion 12, 12' in which the flaps 9, 10, 9', 10' extend in a plane parallel to the opening (see figure 6b ). In addition, the flaps 9, 10, 9', 10' being able to pivot through an amplitude of 180°, the latter can extend parallel to the opening 2 on either side of the guide rod 23, 23' , 24, 24'.

Comme pour les deux autres modes de réalisation de la baie 1a, 1b, les volets 9, 10, 9', 10' montés à pivotement s'étendent sur toute la hauteur de l'ouverture 2, quelle que soit leur position.As for the two other embodiments of the bay 1a, 1b, the flaps 9, 10, 9', 10' pivotally mounted extend over the entire height of the opening 2, whatever their position.

L'usager peut non seulement faire translater les deux volets 9, 10, 9', 10' parallèlement à l'axe longitudinal X de l'ouverture 2, mais également faire pivoter chaque volet 9, 10, 9', 10' entre ses positions de dégagement et d'occultation partielle de la portion d'interaction visuelle associée 12, 12'. En outre, afin de ne pas interagir avec la portion d'interaction visuelle 12, 12' associée à l'autre usager, la largeur du volet 9, 10, 9', 10' est inférieure ou égale, préférentiellement inférieure, à la largeur de l'ouverture 2. De manière avantageuse, chaque rail 13, 14 peut également comprendre une butée située au voisinage du milieu dudit rail, et qui bloque le déplacement du volet 9, 10, 9', 10' au-delà de cette butée. Le mouvement de chaque volet 9, 10, 9', 10' est donc confiné entre le bord latéral considéré de la baie de fenêtre et les butées.The user can not only translate the two flaps 9, 10, 9', 10' parallel to the longitudinal axis X of the opening 2, but also rotate each flap 9, 10, 9', 10' between its positions of release and partial concealment of the associated visual interaction portion 12, 12'. Furthermore, in order not to interact with the visual interaction portion 12, 12' associated with the other user, the width of the flap 9, 10, 9', 10' is less than or equal to, preferably less than, the width of the opening 2. Advantageously, each rail 13, 14 may also comprise an abutment located near the middle of said rail, and which blocks the movement of the flap 9, 10, 9', 10' beyond this stop. The movement of each flap 9, 10, 9', 10' is therefore confined between the considered side edge of the window opening and the stops.

Selon une alternative non représentée de ce troisième mode de réalisation, les extrémités opposées de la tige de guidage sont logées dans des perçages ménagés dans les bords supérieur et inférieur de la baie. Dans cette alternative, le volet n'est évidemment pas mobile à translation, mais uniquement à pivotement.According to an alternative, not shown, of this third embodiment, the opposite ends of the guide rod are housed in holes made in the upper and lower edges of the opening. In this alternative, the flap is obviously not movable in translation, but only in pivoting.

Selon une variante de réalisation non représentée du volet pivotant 9, 10, 9', 10', chaque volet comprend au moins deux panneaux superposés et montés sur la même tige de guidage. De la sorte, l'usager peut choisir de ne faire pivoter que l'un ou l'autre des panneaux. Cela permet à l'usager de ne couvrir qu'une portion selon la hauteur de l'ouverture de la portion d'interaction visuelle, et moduler de fait la quantité de lumière occulter par le volet.According to a variant embodiment not shown of the pivoting flap 9, 10, 9', 10', each flap comprises at least two superimposed panels and mounted on the same guide rod. In this way, the user can choose to rotate only one or the other of the panels. This allows the user to cover only a portion according to the height of the opening of the visual interaction portion, and in fact modulate the amount of light obscured by the shutter.

Dans les trois modes de réalisation, les volets 7, 7', 8, 8', 9, 9', 10, 10' peuvent être réalisés en un matériau opaque, ou bien en un matériau semi-transparent permettant au volet en position d'occultation de laisser passer une partie de la lumière. A titre d'exemple, dans le second mode de réalisation de la baie 1b, une partie des volets 7, 7' peut être opaque tandis qu'une autre partie des volets 8, 8' peut être semi-transparente. Les volets 7, 7'; 8, 8' peuvent aussi présenter des largeurs différentes, pourvue que la largeur du plus grand des volets 7, 7' soit inférieure ou égale à la largeur de l'ouverture 2 lorsque la baie de fenêtre 1a ne comprend qu'un volet 7, 7' par portion d'interaction visuelle associée 12, 12', et que la largeur du plus grand des volets 7, 7' soit inférieure ou égale à la demi-largeur de l'ouverture 2 lorsque la baie de fenêtre 1b, 1c comprend deux volets 7, 7', 8, 8', 9, 9', 10, 10' par portion d'interaction visuelle associée 12, 12'.In the three embodiments, the flaps 7, 7', 8, 8', 9, 9', 10, 10' can be made of an opaque material, or else of a semi-transparent material allowing the flap in position to blackout to let some of the light through. By way of example, in the second embodiment of the bay 1b, part of the flaps 7, 7' can be opaque while another part of the flaps 8, 8' can be semi-transparent. The flaps 7, 7'; 8, 8' can also have different widths, provided that the width of the largest of the shutters 7, 7' is less than or equal to the width of the opening 2 when the window opening 1a comprises only one shutter 7, 7' per associated visual interaction portion 12, 12', and that the width of the largest of the shutters 7, 7' is less than or equal to the half-width of the opening 2 when the window opening 1b, 1c comprises two flaps 7, 7', 8, 8', 9, 9', 10, 10' per associated visual interaction portion 12, 12'.

Les modes de réalisation décrits ci-dessus ne sont nullement limitatifs, et des modifications peuvent y être apportées sans sortir de la portée des revendications. Par exemple, il est possible de combiner les deuxième et troisième modes de réalisation, c'est-à-dire monter des volets pivotants sur deux paires de rails en regard. La baie de fenêtre peut également comprendre un unique rail supérieur monté sur le bord supérieure de ladite baie. Dans ce cas précis, le bord inférieur de la baie comprend des moyens de maintien mécaniques et/ou magnétiques adaptés pour coopérer avec l'extrémité considérée de l'axe de guidage du volet, permettant d'immobiliser ledit volet dans sa position de dégagement ou d'occultation.The embodiments described above are in no way limiting, and modifications can be made thereto without departing from the scope of the claims. For example, it is possible to combine the second and third embodiments, that is to say to mount pivoting shutters on two pairs of opposite rails. The window opening may also include a single top rail mounted on the top edge of said opening. In this specific case, the lower edge of the bay comprises mechanical and/or magnetic holding means suitable for cooperating with the considered end of the guide pin of the flap, making it possible to immobilize said flap in its release or concealment position.
