Description

La présente invention concerne les dispositifs de ventilation ou d'aération et/ou d'éclairage destinés à être placés en paroi des bâtiments, le plus couramment en toiture.The present invention relates to ventilation or aeration and / or lighting devices intended to be placed on the wall of buildings, most commonly on the roof.

On connaît des dispositifs de ce type tels que lanternaux, fenêtres à tabatières, ou exutoires de fumées. Ces dispositifs, outre leurs fonctions spécifiques présentent tous un impératif qui est l'étanchéité de leur liaison à la paroi sur laquelle ils sont fixés. Par simplification on utilisera, dans la suite de ce mémoire, pour ces parois les termes de "toit" ou "toiture", étant bien entendu, que les dispositifs concernés, bien que s'appliquant essentiellement aux toitures, peuvent également être placés sur des parois sensiblement verticales.Devices of this type are known such as skylights, snuff windows, or smoke vents. These devices, in addition to their specific functions, all have an imperative which is the tightness of their connection to the wall on which they are fixed. For the sake of simplification, the terms "roof" or "roof" will be used for these walls in the following description, it being understood that the devices concerned, although essentially applying to roofs, can also be placed on substantially vertical walls.

Ces dispositifs sont donc placés en toiture et d'une manière générale, ces toitures présentent un relief destiné à rigidifier les éléments de toiture, et à guider les écoulements d'eau. Fréquemment, ce relief se présente sous forme de nervures, dirigées selon la plus grande pente du toit.These devices are therefore placed on the roof and, in general, these roofs have a relief intended to stiffen the roof elements, and to guide the water flows. Frequently, this relief is in the form of ribs, directed along the greatest slope of the roof.

Pour la mise en place des dispositifs d'aération ou d'éclairage, une ouverture de dimension correspondante est prévue ou réalisée dans la toiture ; le dispositif est placé de manière à recouvrir cette ouverture, et est fixé à la toiture. Des moyens destinés à assurer l'étanchéité entre la toiture et le cadre ou le châssis du dispositif sont prévus.For the installation of ventilation or lighting devices, an opening of corresponding size is provided or made in the roof; the device is placed so as to cover this opening, and is fixed to the roof. Means intended to ensure the seal between the roof and the frame or the chassis of the device are provided.

Dans les techniques connues, l'étanchéité est couramment réalisée par interposition d'un joint de type mastic silicone entre la toiture et le cadre du dispositif. Ce type de joint présente plusieurs inconvénients. D'une part, il nécessite lors de la réalisation, un temps de main d'oeuvre relative­ment important, ceci étant aggravé du fait des difficultés connues du travail en hauteur sur toitures. D'autre part, il est malaisé d'obtenir un joint régulier, et, outre un aspect peu esthétique, on risque d'obtenir une étanchéité douteuse, d'autant plus que l'épaisseur de joint peut être importante dans le cas d'un relief de toiture prononcéIn known techniques, sealing is commonly achieved by interposing a seal of silicone sealant type between the roof and the frame of the device. This type of seal has several drawbacks. On the one hand, it requires during production, a relatively long labor time, this being aggravated due to the known difficulties of working at height on roofs. On the other hand, it is difficult to obtain a regular seal, and, in addition to an unattractive appearance, there is a risk of obtaining a doubtful seal, especially since the thickness of the seal may be significant in the case of a pronounced roof relief

D'autres moyens sont connus pour essayer d'améliorer la liaison entre le cadre du dispositif et la toiture. On connaît en particulier des dispositifs dont le cadre est conformé selon le relief de la toiture, et constitue de ce fait un élément s'intégrant dans la toiture. Toutefois, ces dispositifs ne peuvent qu'être préfabriqués ou moulés dans le cas de réalisations en matières plastiques, et de ce fait ne peuvent s'adapter qu'à un seul profil d'éléments de toit. Il faut alors pour le fabricant soit réaliser ces dispositifs à la demande, soit stocker un nombre important de modèles différents prévus pour s'adapter à chaque type de toiture. Ces deux solutions ne sont bien évidemment pas satisfaisantes d'un point de vue économique.Other means are known to try to improve the connection between the frame of the device and the roof. We know in particular devices whose frame is shaped according to the relief of the roof, and therefore constitutes an element integrating into the roof. However, these devices can only be prefabricated or molded in the case of plastic constructions, and therefore can only be adapted to a single profile of roof elements. It is then necessary for the manufacturer either to make these devices on demand, or to store a large number of different models provided to adapt to each type of roof. These two solutions are obviously not satisfactory from an economic point of view.

Il est également précisé qu'un aspect important dans ces dispo­sitifs est le matériau dans lequel ils sont réalisés. Tenant compte du fait que ces dispositifs sont directement soumis aux intempéries, au soleil, au vent, au poids de la neige, etc., leur matériau constitutif doit être apte à résister à toutes ces contraintes.It is also specified that an important aspect in these devices is the material in which they are made. Taking into account the fact that these devices are directly subjected to weather, sun, wind, the weight of snow, etc., their constituent material must be able to withstand all these constraints.

La présente invention a pour but de résoudre les différents problè­mes précités, et de proposer un dispositif présentant de très bonnes qualités de résistance aux intempéries et d'étanchéité à la pluie et au vent lorsqu' il est placé en paroi d'un bâtiment.The present invention aims to solve the various aforementioned problems, and to provide a device having very good qualities of resistance to weathering and sealing against rain and wind when it is placed on the wall of a building.

Pour atteindre ces buts, il est proposé un dispositif d'aération ou d'éclairage destiné à être placé en paroi d'un bâtiment et plus particuliè­rement en toiture, du type comportant un bâti fixe, et des moyens de liaison et d' étanchéité entre ce châssis et ladite paroi. Conformément à l'invention, le dispositif est caractérisé en ce que le bâti est composé d'un châssis rigide revêtu extérieurement de feuilles métalliques dont la partie inférieure forme une costière dont les deux côtés latéraux épousent la forme des panneaux de la paroi, le côté supérieur (dans le sens de la paroi) est plan et situé à une hauteur correspondant aux zones basses du profil des panneaux pour être placée en-dessous de ceux-ci, le côté inférieur comporte une partie plane à une hauteur correspondant aux zones hautes du profil des panneaux pour être placée au-dessus de ceux-ci, et la partie plane se prolongeant par un bord replié vers le bas et découpé de façon à épouser le profil des panneaux, des closoirs en matériau compressible pré­formé selon ledit profil, étant disposés entre les panneaux de toiture et lesdits côtés inférieurs et supérieurs.To achieve these goals, it is proposed a ventilation or lighting device intended to be placed on the wall of a building and more particularly on the roof, of the type comprising a fixed frame, and means of connection and sealing between this chassis and said wall. According to the invention, the device is characterized in that the frame is made up of a rigid frame externally coated with metal sheets, the lower part of which forms a curb whose two lateral sides match the shape of the panels of the wall, the side upper (in the direction of the wall) is flat and located at a height corresponding to the low areas of the profile of the panels to be placed below them, the lower side has a flat part at a height corresponding to the high areas of the profile of the panels to be placed above them, and the flat part extending by an edge folded down and cut so as to match the profile of the panels, closers made of compressible material preformed according to said profile, being arranged between the roof panels and said lower and upper sides.

Avantageusement le revêtement extérieur formant costière est constitué de quatre feuilles, (une par côté du cadre) d'aluminium prélaqué, les quatre feuilles étant reliées entre elles par pliage au niveau des angles.Advantageously, the outer covering forming a curb consists of four sheets (one per side of the frame) of prepainted aluminum, the four sheets being interconnected by folding at the corners.

Avantageusement encore, les côtés supérieurs et inférieurs de la costière comportent une partie médiane cintrée reliant respectivement leurs parties planes à leur parties supérieures revêtant le cadre.Advantageously also, the upper and lower sides of the curb have a curved middle part respectively connecting their flat parts to their upper parts covering the frame.

Grace aux différentes caractéristiques exprimées ci-dessus, le dispositif selon l'invention présente une étanchéité remarquable et sa pose est grandement facilitée par le fait que les closoirs d'étanchéités spécifiques aux différents profils de panneaux de toiture sont préfabriqués, et que, hormis la découpe du bord replié du côté inférieur de la costière, celle-ci peut s'adapter à de nombreux profils de panneaux, dans la mesure, bien sûr où ceux-ci ne présentent pas de profils de hauteurs trop différentes.Thanks to the different characteristics expressed above, the device according to the invention has a remarkable seal and its installation is greatly facilitated by the fact that the specific sealing closers for the different profiles of roofing panels are prefabricated, and that, apart from cutting the folded edge on the lower side of the curb , it can be adapted to many panel profiles, provided, of course, that these do not have profiles of too different heights.

D'autres caractéristiques et avantages apparaîtront lors de la description qui va être faite à titre d'exemple d'un mode de réalisation de l'invention, appliquée à des dispositifs d'éclairage zénithal de locaux couverts.Other characteristics and advantages will become apparent from the description which will be given by way of example of an embodiment of the invention, applied to overhead lighting devices for covered premises.

Il est précisé que, afin de faciliter la lecture des différents dessins, ceux-ci ne sont pas tous exécutés à la même échelle et pour plus de clarté, certains éléments n'ont été représentés que schématiquement.It is specified that, in order to facilitate the reading of the various drawings, these are not all executed on the same scale and for greater clarity, certain elements have been represented only schematically.

La figure 1 montre l'adaptation du dispositif sur une toiture formée de panneaux nervurés 1, 2, 3 et 5 qui entoure une ouverture 4. Pour faciliter la compréhension de l'invention, le dispositif et les deux panneaux supérieur 5 et inférieur 2, sont représentés décalés l'un par rapport à l'autre. On comprend aisément que, une fois la mise en place terminée, le côté inférieur 11 est au-dessus du panneau 2, et le panneau 5 est au-dessus du côté supérieur 12.FIG. 1 shows the adaptation of the device on a roof formed by ribbed panels 1, 2, 3 and 5 which surrounds an opening 4. To facilitate understanding of the invention, the device and the two upper 5 and lower 2 panels, are shown offset from each other. It is easily understood that, once the installation is complete, the lower side 11 is above the panel 2, and the panel 5 is above the upper side 12.

Le dispositif comporte un châssis rigide 20 à parois perpendiculaires au plan moyen de la toiture, revêtu extérieurement de feuilles 33, 34, 35 et 36 d'aluminium prélaqué. Les deux feuilles 34 et 36 formant les côtés latéraux 13 et 14, sont pliées pour former les nervures 15 et 16 de façon à épouser le profil des nervures des panneaux de toiture, et recouvrent les nervures 6 et 7 se trouvant aux bords de l'ouverture 4. Une bande de joint 17 est interposée entre les nervures 15 et 16 des côtés latéraux 13 et 14 et les nervures 6 et 7 des panneaux, avant fixation par vissage au moyen de vis autotaraudeuses 49.The device comprises a rigid frame 20 with walls perpendicular to the mean plane of the roof, externally coated with sheets 33, 34, 35 and 36 of prepainted aluminum. The two sheets 34 and 36 forming the lateral sides 13 and 14, are folded to form the ribs 15 and 16 so as to match the profile of the ribs of the roofing panels, and cover the ribs 6 and 7 located at the edges of the opening 4. A joint strip 17 is interposed between the ribs 15 and 16 of the lateral sides 13 and 14 and the ribs 6 and 7 of the panels, before fixing by screwing by means of self-tapping screws 49.

La feuille 35 comporte une partie pleine formant le côté supérieur 12 dans le même plan que les partie non nervurées des côtés latéraux 13 et 14, et vient se placer en-dessous du bord du panneau supérieur 5, un profil d'étanchéité 18, préformé selon le profil des panneaux de toiture, étant intercalé au niveau du recouvrement. La fixation est également assurée par des vis 49, dans les zones en creux 5a du panneau 5.The sheet 35 has a solid part forming the upper side 12 in the same plane as the non-ribbed parts of the lateral sides 13 and 14, and is placed below the edge of the upper panel 5, a sealing profile 18, preformed according to the profile of the roofing panels, being inserted at the level of the covering. The fixing is also ensured by screws 49, in the hollow areas 5a of the panel 5.

La feuille 33 formant le côté inférieur 11 comporte une face plane 19, décalée en hauteur par rapport au côté 12, d'une distance corres­pondant à la hauteur des nervures 6 et 7 des panneaux 2. De cette façon, cette face plane 19 vient recouvrir le bord du panneau inférieur 2, et se prolonge par un bord 21 replié vers le bas sensiblement à angle droit et comportant des découpes 22 aux formes du profil du panneau 2, le bord 21 pouvant ainsi épouser précisément le dit profil. Un contre-profil d' étanchéité 23 (non visible sur la figure 1) est interposé entre la face plane 19 et le bord du panneau 2 qu'elle recouvre, la fixation étant assurée par des vis 49 placées uniquement au niveau des nervures dudit panneau.The sheet 33 forming the lower side 11 has a flat face 19, offset in height relative to the side 12, by a distance corresponding to the height of the ribs 6 and 7 of the panels 2. In this way, this flat face 19 comes to cover the edge of the lower panel 2, and is extended by an edge 21 folded down substantially at a right angle and comprising cutouts 22 in the shapes of the profile of the panel 2, the edge 21 thus being able to precisely match said profile. A sealing counter-profile 23 (not visible in FIG. 1) is interposed between the flat face 19 and the edge of the panel 2 which it covers, the fixing being ensured by screws 49 placed only at the ribs of said panel .

Les liaisons entre les quatre feuilles 33, 34, 35 et 36 sont assu­rées par pliage 24 et 25 ; les pliages étant toujours réalisés de façon à ne pas constituer d'obstacle aux écoulements d'eau. Ainsi le pliage 24 sera rabattu vers le côté latéral, et le pliage 25 sera lui rabattu vers le côté inférieur.The connections between the four sheets 33, 34, 35 and 36 are provided by folding 24 and 25; the folds being always carried out so as not to constitute an obstacle to the flow of water. Thus the fold 24 will be folded down to the lateral side, and the fold 25 will be folded down towards the lower side.

On retrouve sur les autres figures les éléments précédemment décrits. Le dessin de la figure 2 montre en plus la constitution de la struc­ture assurant la rigidité du dispositif. On voit le châssis 20 constitué de panneaux 26 de contre-plaqué ou matériau similaire, revêtus intérieurement et sur toute sa hauteur, de feuilles d'aluminium prélaqué 27 et 28. Ces feuilles sont repliées à leurs parties inférieures 29 et 30 pour recouvrir le chant inférieur des panneaux 26. La partie inférieure 29 s'étend parallèle­ment aux côtés supérieurs 12 ou latéraux 13 et 14 (voir figure 3) avec interposition d'une couche de matériau isolant rigide 31. La partie inférieure 30 de la feuille 28 correspond au côté inférieur 19, est repliée une deuxième fois vers le haut pour former un repli 32. Cette disposition est en particulier prévue pour faciliter la mise en place du dispositif dans l'ouverture de la toiture, le côté supérieur 12 pouvant être glissé sous le panneau supérieur 5, et le côté inférieur 11 pouvant venir s'appliquer sur le panneau inférieur 2, le repli 32 ne constituant pas de gêne, et même éventuellement pouvant constituer un guidage lors de l'introduction du châssis dans l'ouverture de la toiture.The elements previously described are found in the other figures. The drawing of Figure 2 also shows the constitution of the structure ensuring the rigidity of the device. We see the frame 20 consisting of panels 26 of plywood or similar material, coated internally and over its entire height, with prepainted aluminum sheets 27 and 28. These sheets are folded at their lower parts 29 and 30 to cover the edge lower of the panels 26. The lower part 29 extends parallel to the upper 12 or lateral 13 and 14 sides (see FIG. 3) with the interposition of a layer of rigid insulating material 31. The lower part 30 of the sheet 28 corresponds to the side lower 19, is folded a second time upwards to form a fold 32. This arrangement is in particular provided to facilitate the positioning of the device in the opening of the roof, the upper side 12 being able to be slid under the upper panel 5, and the lower side 11 can come to be applied on the lower panel 2, the fold 32 not constituting discomfort, and even possibly being able to constitute a guide during the introduction of the frame is in the opening of the roof.

On remarquera que les feuilles d'aluminium intérieures 27 et 28, et extérieures 33, 34, 35 et 36 ne sont pas en contact, et de ce fait, ne créent pas de pont thermique les feuilles 35 et 33 sont cintrées suivant un arrondi de grand rayon pour faciliter les écoulements.It will be noted that the inner aluminum sheets 27 and 28, and the outer sheets 33, 34, 35 and 36 are not in contact, and therefore do not do not create a thermal bridge the sheets 35 and 33 are bent along a rounded radius to facilitate flows.

Sur la partie droite de la figure 3 et sur la figure 4 est représen­tée une variante de l'invention adaptée aux toitures isolantes. Dans cette variante, les panneaux 26 du châssis 20 se prolongent vers le bas d'une distance correspondante à l'épaisseur de la couche de matériau isolant 31' qui est prévue pour correspondre à l'épaisseur de l'isolant en place sous la toiture.In the right part of FIG. 3 and in FIG. 4 is shown a variant of the invention suitable for insulating roofs. In this variant, the panels 26 of the chassis 20 extend downwards by a distance corresponding to the thickness of the layer of insulating material 31 ′ which is provided to correspond to the thickness of the insulation in place under the roof. .

On remarque sur la figure 4 que la partie inférieure 29′ du revêtement intérieur 27 couvre tout l'isolant, celui-ci étant maintenu par collage sur ladite partie 29′, de même que sur le bord 12 de la feuille extérieure 35. On notera qu'il n'y a pas de pont thermique, les feuilles d' aluminium intérieure et extérieure ne se rejoignant en aucun endroit.Note in FIG. 4 that the lower part 29 ′ of the inner covering 27 covers all the insulation, the latter being held by gluing on said part 29 ′, as well as on the edge 12 of the outer sheet 35. It will be noted that there is no thermal bridge, the aluminum sheets inside and outside meeting in no place.

Du côté inférieur (sur la droite de la figure 4), on remarquera l'absence d'isolant, l'isolation étant réalisée à cet endroit par le matériau isolant en place sous la toiture.On the lower side (on the right of Figure 4), we will note the absence of insulation, the insulation being carried out at this location by the insulating material in place under the roof.

On va maintenant décrire les caractéristiques particulières de l'application de l'invention à un dispositif d'éclairage zénithal. Dans cette application, un panneau translucide 51 en matière plastique de type polycar­bonate alvéolaire à triple paroi est adapté sur le châssis 20 pour en obturer l'ouverture de manière étanche, tout en laissant passer un maximum de luminosité naturelle. De plus, le polycarbonate alvéolaire à triple paroi est remarquable par sa légèreté, son bon coefficient d'isolation thermique, sa résistance aux chocs thermiques et mécaniques, et une bonne conservation de ces caractéristiques lors du vieillissement. Ce matériau étant déjà connu, on rappelle simplement qu'il est formé de trois feuilles 51a, 51b, 51c parallè­les espacées et reliées par des nervures 51d et 51e longitudinales qui défi­nient entre elles des alvéoles 51f.We will now describe the particular characteristics of the application of the invention to an overhead lighting device. In this application, a translucent panel 51 of plastic material of the triple-walled cellular polycarbonate type is fitted to the frame 20 in order to seal the opening in a sealed manner, while allowing a maximum of natural light to pass through. In addition, the triple-walled alveolar polycarbonate is remarkable for its lightness, its good coefficient of thermal insulation, its resistance to thermal and mechanical shocks, and good preservation of these characteristics during aging. This material being already known, it is simply recalled that it is formed from three parallel sheets 51a, 51b, 51c spaced apart and connected by longitudinal ribs 51d and 51e which define cells 51f between them.

Selon l'application particulière de l'invention, le panneau translucide est monté dans un cadre 52 en profilés d'aluminium qui s'adapte sur le bord supérieur du châssis 20.According to the particular application of the invention, the translucent panel is mounted in a frame 52 made of aluminum profiles which fits on the upper edge of the frame 20.

Le profilé d'aluminium 52′ a une section préférée telle que celle représentée sur la figure 6. Il comporte notamment une languette supérieure 53, dirigée vers l'intérieur du cadre et sous laquelle est glissé le bord du panneau translucide 51. La feuille supérieure 51a du panneau est au contact du bord de cette languette, tandis que la feuille inférieure appuie sur un joint 54 logé dans un évidement 55 du profilé 52. Un jeu est réservé sur toute la périphérie du panneau entre celui-ci et la partie verticale 56, liée à la languette 53 du profilé, de façon à permettre la libre dilatation du panneau.The aluminum profile 52 ′ has a preferred section such as that shown in FIG. 6. It notably has an upper tab 53, directed towards the inside of the frame and under which the edge of the translucent panel 51 is slid. The upper sheet 51a of the panel is in contact with the edge of this tongue, while the lower sheet presses on a seal 54 housed in a recess 55 of the profile 52. A clearance is reserved over the entire periphery of the panel between the latter and the vertical part 56 , linked to the tongue 53 of the profile, so as to allow the panel to expand freely.

Grâce à cette disposition et au maintien du panneau pressé sur le joint 54 par la languette 53, l'étanchéité entre le panneau 51 et le cadre 52 est assurée en permanence. De plus, des perçages 57 sont réalisés dans le profilé situé du côté inférieur du dispositif pour permettre l'évacuation des éventuels condensats, ou des infiltrations entre la face supérieure du panneau translu­cide et la languette 53.Thanks to this arrangement and the maintenance of the panel pressed onto the seal 54 by the tongue 53, the seal between the panel 51 and the frame 52 is permanently ensured. In addition, holes 57 are made in the profile located on the lower side of the device to allow the evacuation of any condensate, or infiltration between the upper face of the translucent panel and the tongue 53.

Aux extrémités longitudinales du panneau 51, c'est à dire sur les bords ou débouchent les alvéoles 51f, une cornière 58 est collée par une de ses ailes 58a sous le bord de la feuille supérieure 51a. L'autre aile 58b de la cornière s'étend vers le bas sur toute l'épaisseur du panneau 51, est plaquée contre le chant du panneau et obture les alvéoles de manière toute­fois non étanche. Ce système permet la circulation de l'air et l'évacuation des condensats qui peuvent se créer dans les alvéoles, mais en revanche limite la pénétration et la prolifération de micro-organismes ou d'insectes dans celle-ci.At the longitudinal ends of the panel 51, that is to say on the edges where the cells 51f open, an angle 58 is glued by one of its wings 58a under the edge of the upper sheet 51a. The other wing 58b of the angle iron extends down over the entire thickness of the panel 51, is pressed against the edge of the panel and seals the cells in a non-leaktight manner. This system allows the circulation of air and the evacuation of condensates which can be created in the alveoli, but on the other hand limits the penetration and proliferation of microorganisms or insects in it.

Le profilé 52 comporte par ailleurs de chaque côté de l'évidement 55 recevant le joint 54, deux parois 59 et 60 perpendiculaires au plan du panneau, et formant avec le fond de l'évidement 55 une nervure en forme de U renversé qui vient recouvrir le bord supérieur du châssis 20. Entre la paroi 59 située vers l'extérieur du cadre 52 et les feuilles d'aluminium recouvrant l'extérieur du châssis est interposé un joint 62 assurant l'étanchéité entre cadre et châssis.The profile 52 also comprises on each side of the recess 55 receiving the joint 54, two walls 59 and 60 perpendicular to the plane of the panel, and forming with the bottom of the recess 55 a rib in the shape of an inverted U which covers the upper edge of the frame 20. Between the wall 59 located towards the outside of the frame 52 and the aluminum sheets covering the outside of the frame is interposed a seal 62 ensuring the seal between frame and frame.

La fixation du cadre sur le châssis est assurée par des vis 63 traversant la paroi 60 et vissée de l'intérieur dans les panneaux 26 du cadre 20.The frame is fixed to the frame by screws 63 passing through the wall 60 and screwed from the inside into the panels 26 of the frame 20.

Les profilés du cadre sont coupés à l'onglet et assemblés par des vis autotaraudeuses 64 traversant un profilé et vissés axialement dans des rainures 65 de section circulaire au nombre de trois réalisées respective­ment de chaque côté de l'évidement 55, et vers le bas de la paroi 59.The frame profiles are cut at the tab and assembled by self-tapping screws 64 crossing a profile and axially screwed in grooves 65 of circular section three in number made respectively on each side of the recess 55, and downwards. the wall 59.

Dans la partie centrale du dessin de la figure 6 est représentée une possibilité supplémentaire d'utilisaiton du profilé 52′ formant le cadre 52. Le profilé 52˝ est ici tourné de 90° de façon à présenter la paroi 60 vers le haut. Cette paroi comporte un évidement 66 similaire à l'évidement 55 dans lequel est placé un joint, et elle est placée au contact de la face inférieure du panneau translucide 51. Cette disposition est particulièrement destinée aux dispositifs d'éclairage présentant une surface importante, le profilé supplémentaire étant placé en position intermédiaire pour supporter le panneau 51, par exemple vers son milieu, et éviter qu'il ne fléchisse. Ce profilé intermédiaire est fixé de manière analogue à celle décrite précédem­ment pour l'assemblage du cadre 52, par des vis 67 traversant le châssis et vissé dans les rainures 65 du profilé.In the central part of the drawing of FIG. 6 is shown an additional possibility of using the profile 52 ′ forming the frame 52. The profile 52˝ is here rotated by 90 ° so as to present the wall 60 upwards. This wall has a recess 66 similar to the recess 55 in which a seal is placed, and it is placed in contact with the underside of the translucent panel 51. This arrangement is particularly intended for lighting devices having a large surface, the additional profile being placed in an intermediate position to support the panel 51, for example towards its middle, and prevent it from bending. This intermediate section is fixed in a similar manner to that described above for assembling the frame 52, by screws 67 passing through the frame and screwed into the grooves 65 of the profile.

L'invention n'est pas limitée au dispositif d'éclairage décrit ci-dessus à titre d'exemple. En particulier elle peut s'appliquer à d'autres dispositifs destinés à assurer le passage, à travers une toiture, de cheminée ou gaine de ventilation par exemple. Le châssis peut également recevoir le cadre dormant d'une fenêtre ou d'un exutoire de fumée ; il est également précisé que le dispositif n'est pas réservé aux toitures ou parois formées de panneaux nervurés, mais peut également être utilisé sur des toitures tradition­nelles telles que tuiles, ardoises, etc.The invention is not limited to the lighting device described above by way of example. In particular, it can be applied to other devices intended to ensure the passage, for example through a roof, of a chimney or ventilation duct. The frame can also receive the sleeping frame of a window or a smoke outlet; it is also specified that the device is not reserved for roofs or walls formed from ribbed panels, but can also be used on traditional roofs such as tiles, slates, etc.
