Description

Domaine techniqueTechnical area

La présente invention concerne un caisson de préférence lumineux à cadre interne mobile. Ce caisson lumineux est destiné à être intégré à une fausse paroi de type faux plafond.The present invention relates to a preferably light box with movable internal frame. This light box is intended to be integrated in a false wall type false ceiling.

Technique antérieurePrior art

De manière classique, les caissons de préférence lumineux comprennent un cadre interne muni au moins d'une nappe tendue fixée à la base dudit cadre interne, une enveloppe destinée à être fixée à une paroi et comportant un cadre externe et un fond, et un ensemble charnière reliant le cadre interne et l'enveloppe de manière à permettre un basculement dudit cadre interne par rapport à l'enveloppe du caisson.In a conventional manner, the luminous preference boxes comprise an internal frame provided with at least one stretched sheet attached to the base of said inner frame, an envelope intended to be fixed to a wall and comprising an outer frame and a bottom, and a set hinge connecting the inner frame and the casing so as to allow tilting of said inner frame relative to the casing of the box.

En particulier, l'enveloppe peut être équipée de moyens d'éclairage et la nappe peut être du type translucide. Le caisson peut encore comprendre, de manière connue, des éléments raidisseurs pour renforcer sa rigidité.In particular, the envelope may be equipped with lighting means and the sheet may be of the translucent type. The box may further comprise, in a known manner, stiffening elements to reinforce its rigidity.

Pour permettre les opérations de maintenance, tant de la face interne de la nappe tendue (nettoyage) que celle des moyens d'éclairage (nettoyage et échange des tubes fluorescents par exemple), le cadre interne est mobile par rapport à l'enveloppe du caisson.To allow maintenance operations, both of the inner face of the stretched web (cleaning) and that of the lighting means (cleaning and exchange of fluorescent tubes for example), the inner frame is movable relative to the casing of the box .

A cet égard, le cadre interne peut par exemple être articulé par rapport à l'enveloppe du caisson. On connaît déjà une articulation d'un cadre interne par rapport à l'enveloppe telle que celle décrite dans le document FR 2 911 619 . Cette articulation comprend une première partie montée sur une face dudit cadre interne en regard du fond de l'enveloppe et une deuxième partie fixée sur ledit fond et montée pivotante par rapport à la première partie. Toutefois, ladite articulation présente plusieurs inconvénients. Ainsi, dans la mesure où la deuxième partie est fixée sur ledit fond, on comprend bien que l'accès pour maintenance aux tubes fluorescents situés à proximité de ladite deuxième partie est délicat. De même, lorsque le cadre interne comprend plusieurs nappes souples, ledit cadre interne a par conséquent une épaisseur importante et on comprend bien qu'il est nécessaire de laisser un jeu important entre l'enveloppe et le cadre interne pour permettre l'ouverture du caisson en faisant pivoter le cadre interne. Ce jeu trop important est inesthétique et doit être comblé par des joints souples de grandes dimensions afin d'éviter que des poussières contenues derrière le faux plafond ne tombent dans le local situé sous ledit faux plafond. Enfin, si le caisson se trouve à l'aplomb d'objets de grande hauteur tels que des armoires, la rotation du cadre interne pourra être incomplète voire impossible.In this regard, the internal frame may for example be articulated with respect to the casing of the box. It is already known to articulate an internal frame with respect to the envelope such as that described in the document FR 2 911 619 . This articulation comprises a first portion mounted on one face of said inner frame facing the bottom of the envelope and a second portion fixed on said bottom and pivoting relative to the first part. However, said articulation has several disadvantages. Thus, insofar as the second part is fixed on said bottom, it is clear that maintenance access to the fluorescent tubes located near said second part is difficult. Similarly, when the inner frame comprises a plurality of flexible plies, said inner frame therefore has a large thickness and it is understood that it is necessary to leave a large clearance between the casing and the internal frame to allow the opening of the box by rotating the internal frame. This too important game is unsightly and must be filled by large flexible joints to prevent dust from behind the false ceiling falling into the room under said false ceiling. Finally, if the box is in line with tall objects such as cabinets, the rotation of the internal frame may be incomplete or impossible.

Exposé de l'inventionPresentation of the invention

Le but de la présente invention est donc de pallier les inconvénients précédemment cités et de proposer une solution permettant de réaliser de façon aisée et en toute sécurité, notamment pour des opérations de maintenance, l'ouverture d'un caisson pouvant être disposée à l'aplomb d'objets de grande hauteur et comporter un cadre interne de grande épaisseur sans devoir laisser un jeu trop important autour dudit cadre interne.The object of the present invention is therefore to overcome the aforementioned drawbacks and to propose a solution making it possible to easily and securely, in particular for maintenance operations, the opening of a box that can be arranged at the door. plumb objects high and have a thick internal frame without having too much play around said internal frame.

Conformément à l'invention, il est donc proposé un caisson destiné à être intégré à une fausse paroi de type faux plafond, comprenant un cadre interne mobile à la base duquel est fixée au moins une nappe tendue, une enveloppe destinée à recevoir ledit cadre interne et au moins un mécanisme reliant ledit cadre interne à ladite enveloppe. Ledit caisson est remarquable en ce que le mécanisme permet un mouvement dudit cadre interne par rapport à ladite enveloppe, combinant successivement une phase de translation sensiblement verticale et une phase de translation sensiblement horizontale.According to the invention, it is therefore proposed a box intended to be integrated in a false wall false ceiling type, comprising a mobile inner frame at the base of which is fixed at least one stretched sheet, an envelope for receiving said internal frame and at least one mechanism connecting said inner frame to said envelope. Said box is remarkable in that the mechanism allows a movement of said inner frame relative to said envelope, successively combining a substantially vertical translation phase and a substantially horizontal translation phase.

De préférence, le mécanisme comprend au moins un support télescopique apte à s'étendre selon un axe sensiblement vertical et fixé à son extrémité supérieure à l'enveloppe du caisson et solidaire à son extrémité inférieure du cadre interne par une liaison "glissière".Preferably, the mechanism comprises at least one telescopic support adapted to extend along a substantially vertical axis and fixed at its upper end to the casing of the box and secured at its lower end of the inner frame by a "slide" connection.

Selon un mode de réalisation préférentiel, le mécanisme comprend au moins un support télescopique reliant deux cotés opposés du cadre interne à l'enveloppe, lesdits supports télescopiques étant placés dans le plan vertical contenant le centre de gravité du cadre interne.According to a preferred embodiment, the mechanism comprises at least one telescopic support connecting two opposite sides of the inner frame to the casing, said telescopic supports being placed in the vertical plane containing the center of gravity of the internal frame.

Selon un mode de réalisation encore plus avantageux, le mécanisme comprend deux supports télescopiques reliant deux cotés opposés du cadre interne à l'enveloppe, lesdits supports télescopiques étant disposés symétriquement de part et d'autre du plan vertical contenant le centre de gravité du cadre interne. Les deux supports télescopiques de chacun des deux cotés opposés du cadre interne sont de préférence écartés d'une distance inférieure au quart de la longueur dudit coté opposé.According to an even more advantageous embodiment, the mechanism comprises two telescopic supports connecting two opposite sides of the inner frame to the casing, said telescopic supports being disposed symmetrically on either side of the vertical plane containing the center of gravity of the internal frame. . The two telescopic supports of each of the two opposite sides of the inner frame are preferably separated by a distance less than a quarter of the length of said opposite side.

De préférence, le cadre interne comporte sur sa face supérieure une rainure longitudinale en forme générale de T inversé et l'extrémité inférieure de chaque support télescopique comporte un coulisseau apte à coopérer avec ladite rainure pour permettre le coulissement dans un plan horizontal du cadre interne par rapport au support télescopique.Preferably, the inner frame comprises on its upper face a longitudinal groove in the general shape of inverted T and the lower end of each telescopic support comprises a slide adapted to cooperate with said groove to allow sliding in a horizontal plane of the internal frame by compared to the telescopic support.

Avantageusement, le caisson est muni d'organes de guidage disposés sur la périphérie du cadre interne et d'un joint sur le pourtour du cadre interne et comporte au moins une fermeture de type à targette.Advantageously, the box is provided with guide members disposed on the periphery of the internal frame and a seal on the periphery of the inner frame and comprises at least one fastener type bolt.

Meilleure manière de réaliser l'invention techniqueBest way to realize the technical invention

En référence aux figures 1 à 3, le caisson 1 à cadre interne 2 mobile selon l'invention comprend une enveloppe 3 destinée à recevoir ledit cadre interne 2.With reference to Figures 1 to 3 , the casing 1 with internal frame 2 mobile according to the invention comprises a casing 3 intended to receive said internal frame 2.

Le cadre interne 2 est, en fonctionnement, logé dans l'enveloppe 3 du caisson 1, comme représenté sur la vue la plus à gauche de la figure 1 et est, notamment pour la maintenance, entièrement sorti hors de l'enveloppe 3, comme représenté sur la figure 2. La vue la plus à droite de la figure 1 représente le cadre interne 2 en cours de mouvement.The inner frame 2 is, in operation, housed in the casing 3 of the casing 1, as shown in the leftmost view of the figure 1 and is, especially for maintenance, completely out of the envelope 3, as shown on the figure 2 . The most right view of the figure 1 represents the internal frame 2 during movement.

L'enveloppe 3 est de préférence formée par différents éléments 4 définissants globalement les quatre côtés 5 d'un quadrilatère sur lequel est avantageusement monté un fond (non représenté). Cette enveloppe 3 est destinée à être de préférence intégrée à une fausse paroi de type faux plafond. Lesdits éléments 4 et le fond formant l'enveloppe 3 sont avantageusement, comme dans cet exemple, constitués des éléments de structure, métalliques ou non, du plafond du local recevant le faux plafond. Toutefois, ces éléments 4 et le fond pourront, par exemple, être des profilés indépendants en tôle pliée, sans sortir du cadre de la présente invention.The envelope 3 is preferably formed by different elements 4 defining generally the four sides 5 of a quadrilateral on which is advantageously mounted a bottom (not shown). This envelope 3 is intended to be preferably integrated in a false wall false ceiling type. Said elements 4 and the bottom forming the envelope 3 are advantageously, as in this example, made of structural elements, metal or not, the ceiling of the room receiving the false ceiling. However, these elements 4 and the bottom may, for example, be independent profiles bent sheet without departing from the scope of the present invention.

Le cadre interne 2 est formé par une lisse 6 elle-même constituée de profils aboutés sur lesquels est fixée au moins une première nappe souple 7 tendue. La lisse est un organe bien connu de l'Homme du Métier dans le domaine des faux plafonds tendus qui est utilisée couramment pour maintenir la nappe souple d'un faux plafond tendu.The inner frame 2 is formed by a rail 6 itself consisting of abutting profiles on which is fixed at least a first flexible sheet 7 stretched. Smooth is an organ well known to those skilled in the art in the field of stretched false ceilings which is commonly used to maintain the flexible sheet of a suspended false ceiling.

Dans la configuration représentée sur les figures 1 à 3, le cadre interne 2 peut être équipé d'une seconde nappe souple 8 tendue située au-dessus de la première nappe souple 7. Par exemple, la première nappe souple 7 est translucide et la deuxième nappe souple 8 est transparente. Cette dernière a notamment pour rôle de protéger la première nappe souple 7 contre les poussières et les insectes qui pourraient se déposer sur celle-ci et qui seraient alors visibles par les usagers situés dans le local sous ladite première nappe souple 7.In the configuration shown on the Figures 1 to 3 , the inner frame 2 may be equipped with a second flexible ply 8 stretched above the first flexible ply 7. For example, the first flexible ply 7 is translucent and the second flexible ply 8 is transparent. The latter has in particular the role of protecting the first flexible sheet 7 against dust and insects that could be deposited on it and which would then be visible by the users located in the room under said first flexible ply 7.

Dans un mode de réalisation préférentiel, le caisson 1 comprend en outre, pour rigidifier le cadre interne 2, des moyens raidisseurs (non représentés) formés d'au moins un longeron s'étendant entre deux profils opposés de la lisse 6 dudit cadre interne 2.In a preferred embodiment, the box 1 further comprises, to stiffen the inner frame 2, stiffening means (not shown) formed of at least one spar extending between two opposite profiles of the rail 6 of said inner frame 2 .

De préférence, le caisson 1 comprend encore des moyens d'éclairage (non représentés), tels que des tubes néons, avantageusement montés sur le fond de l'enveloppe 3 dudit caisson 1. Toutefois, en l'absence de fond, lesdits moyens d'éclairage pourront être fixés sur le "vrai plafond" du local recevant le faux plafond, sans sortir du cadre de la présente invention.Preferably, the box 1 further comprises lighting means (not shown), such as neon tubes, advantageously mounted on the bottom of the envelope 3 said box 1. However, in the absence of background, said lighting means may be fixed on the "true ceiling" of the room receiving the false ceiling, without departing from the scope of the present invention.

Le cadre interne 2 est mobile par un mouvement combinant successivement une phase de translation sensiblement verticale et une phase de translation sensiblement horizontal.The inner frame 2 is movable by a movement successively combining a substantially vertical translation phase and a substantially horizontal translation phase.

On comprend bien que les termes "horizontal" et "vertical" désignent des directions respectivement parallèle et perpendiculaire au faux plafond lorsque celui-ci est horizontal. Il va de soi que ces termes seront à adapter si le faux plafond et donc le cadre interne 2 sont inclinés voire au moins en partie verticaux.It is understood that the terms "horizontal" and "vertical" designate directions respectively parallel and perpendicular to the false ceiling when it is horizontal. It goes without saying that these terms will be adapted if the false ceiling and thus the internal frame 2 are inclined or at least partly vertical.

De même, dans cette description, on suppose que le cadre interne 2 du caisson 1 est disposé horizontalement. Les expressions "supérieure" et "inférieure" utilisées ici se rapportent donc à des positions relatives par rapport au sens vertical. Plus généralement, par exemple dans le cas d'un caisson 1 et d'un cadre interne 2 fixés inclinés ou verticalement, il convient d'interpréter "supérieure" et "inférieure" respectivement dans le sens "proche de la fausse paroi" et "éloigné de la fausse paroi".Similarly, in this description, it is assumed that the inner frame 2 of the box 1 is disposed horizontally. The terms "upper" and "lower" used herein, therefore, refer to positions relative to the vertical direction. More generally, for example in the case of a box 1 and an internal frame 2 fixed inclined or vertically, it is appropriate to interpret "upper" and "lower" respectively in the direction "close to the false wall" and " away from the false wall ".

En référence aux figures 1 à 3, pour assurer le double mouvement du cadre interne 2, ledit caisson 1 comporte un mécanisme 10 comprenant au moins un support télescopique 11 reliant deux cotés opposés du cadre interne 2 à l'enveloppe 3. La liaison du support télescopique 11 à l'enveloppe 3 pourra être réalisée à l'aide d'un élément support 9 disposé à l'intérieur de l'enveloppe 3. Pour des raisons évidentes d'équilibre lors de la translation verticale, ces deux supports télescopiques 11 sont placés dans le plan vertical contenant le centre de gravité du cadre interne 2.With reference to Figures 1 to 3 to ensure the double movement of the inner frame 2, said box 1 comprises a mechanism 10 comprising at least one telescopic support 11 connecting two opposite sides of the inner frame 2 to the casing 3. The connection of the telescopic support 11 to the casing 3 can be performed using a support member 9 disposed within the casing 3. For obvious reasons of balance during the vertical translation, these two telescopic supports 11 are placed in the vertical plane containing the center of gravity of the internal framework 2.

Avantageusement, pour des questions de stabilité lors des différentes translations, le mécanisme 10 comporte deux supports télescopiques 11 reliant deux cotés opposés du cadre interne 2 à l'enveloppe 3 et étant disposés symétriquement de part et d'autre du plan vertical contenant le centre de gravité du cadre interne 2.Advantageously, for reasons of stability during the various translations, the mechanism 10 comprises two telescopic supports 11 connecting two opposite sides of the inner frame 2 to the envelope 3 and being arranged symmetrically on either side of the vertical plane containing the center of severity of the internal framework 2.

Chaque support télescopique 11 est apte à s'étendre selon un axe sensiblement vertical, il est fixé à son extrémité supérieure à l'enveloppe 3 du caisson 1 et il est solidaire à son extrémité inférieure du cadre interne 2 par une liaison "glissière".Each telescopic support 11 is able to extend along a substantially vertical axis, it is fixed at its upper end to the casing 3 of the casing 1 and is secured at its lower end of the inner frame 2 by a "slide" connection.

De préférence, conformément à la figure 3, pour assurer cette liaison "glissière", le cadre interne 2 comporte sur sa face supérieure une rainure 21 longitudinale en forme générale de T inversé, et l'extrémité inférieure de chaque support télescopique 11 comporte un coulisseau 12 apte à coopérer avec ladite rainure 21 pour permettre le coulissement dans un plan sensiblement horizontal du cadre interne 2 par rapport au support télescopique 11.Preferably, in accordance with the figure 3 , to ensure this connection "slide", the inner frame 2 comprises on its upper face a longitudinal groove 21 in the general shape of inverted T, and the lower end of each telescopic support 11 comprises a slider 12 adapted to cooperate with said groove 21 to allow sliding in a substantially horizontal plane of the inner frame 2 relative to the telescopic support 11.

Pour assurer cette liaison "glissière", l'Homme du Métier pourra sans difficulté remplacer la rainure 21 et le coulisseau 12 pour tout autre moyen adapté tel que, par exemple, un rail en forme de I et un organe de roulement sans sortir du cadre de la présente invention.To ensure this link "slide", the skilled person can easily replace the groove 21 and the slider 12 for any other suitable means such as, for example, an I-shaped rail and a rolling member without departing the frame of the present invention.

Pour permettre l'accès à presque tout l'intérieur du caisson 1, les deux supports télescopiques 11 de chacun des deux cotés opposés du cadre interne 2 sont de préférence écartés d'une distance inférieure au quart de la longueur dudit coté opposé.To allow access to almost the entire interior of the box 1, the two telescopic supports 11 of each of the two opposite sides of the inner frame 2 are preferably spaced apart by a distance less than a quarter of the length of said opposite side.

Par ailleurs, le caisson 1 est avantageusement muni d'organes de guidage (non représentés) disposés sur la périphérie du cadre interne 2 pour faciliter la remise en place du cadre interne à l'intérieur de l'enveloppe 3 du caisson 1 lors de la translation verticale, lesdits organes de guidage étant de préférence des roulettes ou des billes.Furthermore, the casing 1 is advantageously provided with guide members (not shown) disposed on the periphery of the inner frame 2 to facilitate the repositioning of the internal frame inside the casing 3 of the box 1 during the vertical translation, said guide members preferably being rollers or balls.

En outre, pour assurer l'étanchéité entre le cadre interne 2 et l'enveloppe 3, on pourra sans difficulté mettre en place un joint (non représentés) par exemple sous forme de balai sur le pourtour du cadre interne 2.In addition, to ensure the seal between the inner frame 2 and the casing 3, it will be easy to set up a seal (not shown) for example in the form of a brush on the periphery of the inner frame 2.

Enfin, pour maintenir le cadre interne 2 en position de fermeture dite de fonctionnement (Cf. la vue la plus à gauche de la figure 1), le caisson 1 comporte de préférence au moins une fermeture (non représentée) de type à targette par exemple.Finally, to maintain the internal frame 2 in said closed operating position (see the leftmost view of the figure 1 ), the casing 1 preferably comprises at least one closure (not shown) of the bolt type for example.

Enfin, on comprend bien que le mécanisme 10 pourra ne comporter qu'un seul support télescopique 11 central reliant le centre du fond de l'enveloppe 3 aux deux cotés opposés du cadre interne 2, le support télescopique 11 comprenant alors un support additionnel horizontal reliant lesdits deux cotés opposés du cadre interne 2. Toutefois, on comprend bien que cette variante n'est pas satisfaisante pour des raisons de stabilité mais surtout parce que le support télescopique 11 disposé dans le caisson 1 dans une position centrale gêne l'accès à l'intérieur du caisson 1 et rend par conséquent délicate la maintenance.Finally, it is clear that the mechanism 10 may comprise only one central telescopic support 11 connecting the center of the bottom of the casing 3 to the two opposite sides of the inner frame 2, the telescopic support 11 then comprising an additional horizontal support connecting said two opposite sides of the inner frame 2. However, it is clear that this variant is not satisfactory for reasons of stability but especially because the telescopic support 11 disposed in the box 1 in a central position hinders access to the the interior of the casing 1 and therefore makes maintenance difficult.

Ainsi avec une configuration telle que décrite précédemment et en référence aux figures 1 et 2, pour ouvrir le caisson 1 et faire sortir le cadre interne 2 de l'enveloppe 3, on fait translater verticalement le cadre interne 2 grâce aux supports télescopiques 11 (Cf. figure 1); puis, lorsque le cadre interne 2 est entièrement dégagé de l'enveloppe 3, les supports télescopiques 11 étant en fin de course, on peut faire alors translater le cadre interne 2 dans un plan horizontal d'un coté ou de l'autre de l'enveloppe 3 afin de dégager successivement toute la surface inférieure du caisson 1, facilitant l'accès à tous les équipements contenus dans ledit caisson 1. Sur la figure 2, on a représenté le cadre interne 2 translaté d'un coté (en trait fort) et de l'autre (partiellement en pointillé) de l'enveloppe 3.Thus with a configuration as described above and with reference to Figures 1 and 2 to open the casing 1 and to remove the inner frame 2 from the casing 3, the inner frame 2 is vertically translated through the telescopic supports 11 (Cf. figure 1 ); then, when the inner frame 2 is completely clear of the casing 3, the telescopic supports 11 being at the end of the stroke, it is then possible to translate the inner frame 2 in a horizontal plane on one side or the other of the envelope 3 in order to clear successively the entire lower surface of the casing 1, facilitating access to all the equipment contained in said box 1. On the figure 2 , the inner frame 2 is shown translated on one side (in bold line) and on the other (partially dotted) of the envelope 3.

Dans cette configuration, après la translation verticale, on comprend bien que le cadre interne 2 se déplace horizontalement parallèlement au faux plafond et que cette translation horizontale du cadre interne 2 peut être réalisée dans un espace réduit et donc même à l'aplomb d'objets de grande hauteur. En effet, l'espace nécessaire à cette translation horizontale doit être au minimum légèrement plus grand que l'épaisseur dudit cadre interne 2.In this configuration, after the vertical translation, it is clearly understood that the inner frame 2 moves horizontally parallel to the false ceiling and that this horizontal translation of the inner frame 2 can be made in a small space and therefore even in line with objects of great height. Indeed, the space required for this horizontal translation must be at least slightly larger than the thickness of said internal frame 2.

Possibilité d'application industriellePossibility of industrial application

Le caisson 1 à cadre interne 2 mobile selon l'invention est de préférence destiné à être intégré seul à une fausse paroi de type faux plafond. Toutefois, ledit caisson 1 peut évidemment être disposé à côté de caissons du même type, de façon à constituer une matrice d'éclairage. En outre, il ressort clairement de la description que le caisson 1 selon l'invention est de construction légère et simple, et que le cadre interne 2 peut être facilement déplacé quelles que soient ses dimensions.The casing 1 with internal frame 2 mobile according to the invention is preferably intended to be integrated alone to a false wall false ceiling type. However, said box 1 can obviously be arranged next to boxes of the same type, so as to form a lighting matrix. In addition, it is clear from the description that the box 1 according to the invention is light and simple construction, and that the inner frame 2 can be easily moved regardless of its dimensions.

Enfin, il est clair que la présente invention ne se limite pas à la seule forme d'exécution de ce caisson 1 à cadre interne 2 mobile ; elle en embrasse, au contraire, toutes les variantes de réalisation et d'application respectant le même principe.Finally, it is clear that the present invention is not limited to the sole embodiment of this box 1 with internal frame 2 mobile; it embraces, on the contrary, all variants of implementation and application respecting the same principle.
