A stringer is formed by a set of joined profiles. A set of receiving pieces is ready to cooperate with the fixing unit to maintain the web. A light source including a set of electroluminescent diodes is integrated into the stringer. The diodes are integrated into a face of the stringer in a direct or partial manner with regard to the flexible web.

Description

Domaine techniqueTechnical area

La présente invention concerne une fausse paroi rétro-éclairée par des sources de lumière, de préférence un faux plafond, pouvant également être employée pour un caisson lumineux ou une structure tridimensionnelle lumineuse.The present invention relates to a false wall backlit by light sources, preferably a false ceiling, which can also be used for a light box or a three-dimensional light structure.

Technique antérieurePrior art

Les fausses parois, notamment les faux plafonds, comprennent classiquement une ou plusieurs lisses d'accrochage qui sont fixées sur chacun des murs et/ou plafonds d'un local, et une nappe souple et généralement opaque, qui est déformée par tension afin que ses bords, pourvus de moyens d'accrochage, puissent venir se fixer auxdites lisses à l'aide de ces moyens d'accrochage, en prenant soin de bien tendre la toile afin d'offrir un aspect esthétiquement soigné.False walls, including false ceilings, conventionally comprise one or more stringers which are fixed on each of the walls and / or ceilings of a room, and a flexible and generally opaque sheet, which is deformed by tension so that its edges, provided with hooking means, can be fixed to said rails with the aid of these attachment means, taking care to stretch the fabric to provide an aesthetically pleasing appearance.

Cette toile est donc tendue parallèlement à une paroi du local de sorte à laisser un espace résiduel situé entre la paroi dudit local et ladite toile. Cet espace résiduel, aussi nommé plénum, permet de loger tous les équipements inesthétiques tels que des câbles électriques, des tuyauteries, etc. Par conséquent, ladite toile permet de masquer ces équipements mais aussi les imperfections des parois du local et d'avoir une surface visible uniforme et propre en retenant notamment les poussières dans ce plénum.This fabric is thus stretched parallel to a wall of the room so as to leave a residual space between the wall of said room and said fabric. This residual space, also called plenum, makes it possible to house all unsightly equipment such as electrical cables, pipes, etc. Consequently, said fabric makes it possible to mask these equipment but also the imperfections of the walls of the room and to have a uniform and clean visible surface by retaining in particular the dust in this plenum.

Toutefois, si l'on souhaite rétro-éclairer le local, puisqu'on ne peut évidemment pas fixer de sources de lumière sur la toile souple, il faut donc mettre en place des sources de lumière dans le plénum en utilisant une toile translucide de façon à ce que les rayons lumineux puissent éclairer le local, ou prévoir une pluralité de caissons lumineux aptes à être intégrés à une paroi ou une fausse paroi et contenant une pluralité de sources de lumière destinées à rétro-éclairer une fausse paroi recouvrant au moins la face inférieure horizontale desdits caissons lumineux.However, if we want to backlight the room, since we can obviously not fix sources of light on the flexible canvas, it is necessary to set up light sources in the plenum using a translucent canvas so that the light rays can illuminate the room, or provide a plurality of light boxes adapted to be integrated into a wall or a false wall and containing a plurality of light sources for backlit a false wall covering at least the lower horizontal face of said light boxes.

Les sources de lumière sont de habituellement de type tubes fluorescents. On peut également mettre en oeuvre, indépendamment ou en combinaison avec les autres types de source de lumière, des fibres optiques ou des blocs de diodes électroluminescentes. Ces sources sont placées sur la paroi recouverte par la fausse paroi ou au fond d'un caisson et occupent donc une partie du plénum.The light sources are usually of the fluorescent tube type. It is also possible, independently or in combination with the other types of light source, to use optical fibers or light-emitting diode blocks. These sources are placed on the wall covered by the false wall or the bottom of a box and thus occupy part of the plenum.

Si ces systèmes conviennent pour réaliser des chemins lumineux, des plafonds tendus ou des cloisons murales, ils sont difficilement adaptables pour réaliser des formes tridimensionnelles en nappes tendues, telles que du mobilier (table basse, fauteuil, etc) ou des objets décoratifs (animaux polygonaux, colonnes, etc).If these systems are suitable for making light paths, stretch ceilings or wall partitions, they are difficult to adapt to make three-dimensional shapes in stretched sheets, such as furniture (coffee table, chair, etc.) or decorative objects (polygonal animals , columns, etc.).

Le but de la présente invention est donc de proposer une alternative aux fausses-parois rétro-éclairées existantes et de proposer une fausse paroi rétro-éclairée par une pluralité de sources de lumière permettant non seulement de réaliser un chemin lumineux, un plafond tendu, une cloison murale, mais aussi des formes tridimensionnelles.The object of the present invention is therefore to propose an alternative to the existing false-backlit walls and to propose a backlit false wall by a plurality of light sources allowing not only to realize a light path, a stretched ceiling, a wall partition, but also three-dimensional shapes.

Résumé de l'inventionSummary of the invention

A cet égard, la présente invention concerne une fausse paroi rétro-éclairée par au moins une source de lumière et comportant au moins une nappe souple translucide tendue accrochée par ses bordures pourvues de moyens d'accrochage à un cadre, ledit cadre étant constitué par une lisse formée de profils aboutés et comprenant des organes de réception aptes à coopérer avec lesdits moyens d'accrochage pour maintenir ladite nappe souple translucide tendue, remarquable en ce que ladite au moins source de lumière est constituée par des diodes électroluminescentes intégrées à la lisse.In this regard, the present invention relates to a false wall backlit by at least one light source and comprising at least one taut translucent flexible sheet hung by its edges provided with attachment means to a frame, said frame being constituted by a smooth formed of abutting profiles and comprising receiving members adapted to cooperate with said attachment means for holding said flexible sheet taut translucent, remarkable in that said at least one light source is constituted by electroluminescent diodes integrated into the beam.

On comprend bien que cette fausse paroi rétro-éclairée est particulièrement simple à mettre en oeuvre, ne nécessitant plus l'installation supplémentaire de sources lumineuses qui sont intégrées aux lisses, et économique, du fait de la faible consommation électrique et de la longévité des diodes électroluminescentes.It is understood that this false backlit wall is particularly simple to implement, no longer requiring the additional installation of light sources that are integrated smooth, and economic, because of the low power consumption and longevity of the diodes emitting.

D'autres avantages et caractéristiques ressortiront mieux de la description détaillée qui va suivre.Other advantages and features will become more apparent from the following detailed description.

Description détaillée de l'inventionDetailed description of the invention

La fausse paroi est rétro-éclairée par au moins une source de lumière. Par rétro-éclairée, on entend dans le présent texte que au moins une source lumineuse est placée en arrière de ladite paroi, c'est-à-dire du coté de la face opposée à la face visible par des observateurs externes.The false wall is backlit by at least one light source. By backlit means in the present text that at least one light source is placed behind said wall, that is to say the side of the face opposite to the visible face by external observers.

Cette fausse paroi est constituée d'au moins une nappe souple translucide tendue accrochée par ses bordures pourvues de moyens d'accrochage à un cadre, ledit cadre étant constitué par une lisse formée de profils aboutés et comprenant des organes de réception aptes à coopérer avec lesdits moyens d'accrochage pour maintenir ladite nappe souple translucide tendue.This false wall consists of at least one taut translucent flexible sheet hung by its borders provided with attachment means to a frame, said frame being constituted by a smooth formed of abutting profiles and comprising receiving members adapted to cooperate with said hooking means for holding said translucent soft sheet taut.

Selon une caractéristique essentielle de l'invention, ladite au moins source de lumière est constituée par des diodes électroluminescentes intégrées à la lisse.According to an essential characteristic of the invention, said at least one light source consists of light-emitting diodes integrated into the beam.

Selon un mode de réalisation préféré, lesdites diodes électroluminescentes sont intégrées à au moins une face de la lisse orientée au moins en partie en regard de ladite nappe souple translucide.According to a preferred embodiment, said light-emitting diodes are integrated in at least one face of the stringer oriented at least in part opposite said translucent flexible sheet.

Dans la mise en oeuvre de la présente invention, on pourra utiliser tous les types de diodes électroluminescentes disponibles, et ne pas se limiter à une couleur donnée.In the practice of the present invention, it will be possible to use all available types of light-emitting diodes, and not be limited to a given color.

Habituellement, les lisses mises en oeuvre pour réaliser des plafonds tendus comportent des logements longitudinaux débouchant sur leurs faces externes. Dans le cadre de la présente invention, on placera avantageusement les diodes électroluminescentes dans lesdits logements.Usually, the rails used to make stretch ceilings comprise longitudinal housings opening on their outer faces. In the context of the present invention, the light-emitting diodes will advantageously be placed in said housings.

L'invention permet ainsi d'obtenir des caissons lumineux, des faux-plafonds lumineux ou encore des fausses cloisons lumineuses dont le rétro-éclairage est périphérique.The invention thus makes it possible to obtain light boxes, luminous false ceilings or else false luminous partitions whose backlighting is peripheral.

Avantageusement, la fausse paroi selon l'invention peut être associée à d'autres sources lumineuses disposées de façon conventionnelle dans le plénum derrière ladite paroi : on obtient ainsi une grande variété possible d'ambiances lumineuses différentes, par basculement entre les sources lumineuses.Advantageously, the false wall according to the invention can be associated with other light sources conventionally arranged in the plenum behind said wall: a wide variety of different lighting atmospheres is thus obtained, by switching between the light sources.

En outre, la toile de la fausse paroi peut être imprimée de motifs et rétro-éclairée à des fins esthétiques, décoratives et/ou publicitaires, sans sortir du cadre de la présente invention.In addition, the fabric of the false wall can be printed patterns and backlit for aesthetic purposes, decorative and / or advertising, without departing from the scope of the present invention.

Application industrielleIndustrial application

La fausse paroi rétro-éclairée conforme à l'invention sera notamment utilisée pour réaliser des faux-plafonds tendus lumineux, des cloisons murales lumineuses, des chemins lumineux, des caissons lumineux, des structures tridimensionnelles en fausses parois tendues, telles que du mobilier (table basse, fauteuil, etc) ou des objets décoratifs (animaux polygonaux, colonnes, etc).The backlit false wall according to the invention will be used in particular to make luminous suspended ceilings, luminous wall partitions, light paths, light boxes, three-dimensional structures in false walls, such as furniture (table bass, armchair, etc.) or decorative objects (polygonal animals, columns, etc.).
