Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention concerne le domaine des faux plafonds.The invention relates to the field of false ceilings.

L'invention concerne plus particulièrement une nappe souple destinée à la réalisation d'un faux plafond, ladite nappe étant constituée de deux toiles superposées et assemblées en périphérie sur un moyen d'accroche, l'une des toiles étant pleine, l'autre étant ajourée.The invention relates more particularly to a flexible sheet intended for the production of a false ceiling, said sheet being made up of two superposed canvases and assembled at the periphery on a means of attachment, one of the canvases being solid, the other being openwork.

Par toile ajourée, on entend une toile comportant des zones évidée (ou découpée).By openwork canvas, we mean a canvas comprising hollowed-out (or cut-out) zones.

La nappe souple est destinée notamment, mais non exclusivement, à la réalisation de faux plafonds offrant des motifs visuels lumineux.The flexible sheet is intended in particular, but not exclusively, for the production of false ceilings offering luminous visual patterns.

ETAT DE LA TECHNIQUESTATE OF THE ART

Il est connu de réaliser des faux-plafonds présentant des motifs lumineux. Pour ce faire, les faux-plafonds comprennent une nappe souple dite double, composée de deux toiles superposées, i.e. disposées l'une sur l'autre, la toile du dessus étant translucide et pleine, la toile du dessous étant opaque et découpée (ou perforée) selon une forme donnée (motif), ladite nappe étant placée sous des moyens lumineux disposés dans l'espace résiduel ménagé entre le plafond et le faux-plafond.It is known to make false ceilings with light patterns. To do this, the false ceilings include a so-called double flexible sheet, made up of two superimposed fabrics, ie arranged one on top of the other, the top fabric being translucent and full, the bottom fabric being opaque and cut (or perforated) according to a given shape (pattern), said sheet being placed under luminous means arranged in the residual space provided between the ceiling and the false ceiling.

Un inconvénient majeur des faux-plafonds ainsi réalisés est le rendu visuel lequel n'est pas entièrement satisfaisant. En effet, du fait d'un assemblage des toiles au niveau de leur bordure périphérique, les deux toiles ont tendance à s'écarter légèrement l'une de l'autre. Or l'écartement des toiles impacte le rendu visuel des motifs, et en particulier la netteté de ces derniers.A major drawback of the false ceilings thus produced is the visual rendering which is not entirely satisfactory. Indeed, due to an assembly of the fabrics at their peripheral edge, the two fabrics tend to deviate slightly from each other. However, the spacing of the canvases impacts the visual rendering of the patterns, and in particular the sharpness of the latter.

Par ailleurs, la présence de zone ajourée sur la toile de dessous rend le nettoyage de celle-ci fastidieux.Furthermore, the presence of a perforated zone on the bottom canvas makes cleaning the latter tedious.

Le document EP 2 078 796 A1 divulgue une nappe souple selon le préambule de la revendication indépendante 1.The document EP 2 078 796 A1 discloses a flexible web according to the preamble of independent claim 1.

L'invention vise à remédier à ces problèmes en proposant une nappe souple permettant de réaliser des faux-plafonds présentant des motifs visuels, avantageusement lumineux, nets et pouvant être facilement nettoyée.The invention aims to remedy these problems by proposing a flexible sheet making it possible to produce false ceilings having visual patterns, advantageously bright, clean and can be easily cleaned.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

A cet effet, et selon un premier aspect, l'invention propose une nappe souple destinée à la réalisation d'un faux plafond dans un local, ladite nappe étant constituée de deux toiles superposées et assemblées entre elles au niveau de leur bordure périphérique, l'une des toiles étant pleine, l'autre étant ajourée. La nappe souple selon l'invention est remarquable en ce que la toile disposée au-dessus, laquelle est ajourée, présente un grammage supérieur à celui de la toile pleine disposée au dessous de sorte que la toile ajourée est maintenue apposée sur la toile pleine lorsque la nappe est accrochée sur la lisse.To this end, and according to a first aspect, the invention proposes a flexible sheet intended for the production of a false ceiling in a room, said sheet being made up of two superposed fabrics and assembled together at their peripheral edge, the one of the canvases being solid, the other being perforated. The flexible web according to the invention is remarkable in that the fabric placed above, which is perforated, has a weight greater than that of the full fabric placed below so that the perforated fabric is kept affixed to the full fabric when the tablecloth is hung on the rail.

De par cet arrangement, la toile de dessus est maintenue plaquée sur la toile de dessous. En supprimant l'écartement induit entre les toiles des nappes de l'art antérieur, les faux-plafonds réalisés à l'aide d'une nappe selon l'invention offre un rendu des motifs formés par la toile ajourée net. Par ailleurs, la toile inférieure étant pleine, le nettoyage de la nappe s'en trouve facilité.By this arrangement, the top fabric is kept flat on the bottom fabric. By eliminating the spacing induced between the fabrics of the sheets of the prior art, the false ceilings produced using a sheet according to the invention offers a rendering of the patterns formed by the openwork fabric. Furthermore, the lower canvas being solid, the cleaning of the web is facilitated.

Avantageusement, la toile ajourée est opaque.Advantageously, the perforated canvas is opaque.

Avantageusement, la toile pleine est en tout ou partie translucide ou transparente.Advantageously, the solid canvas is wholly or partly translucent or transparent.

Avantageusement, la nappe est pourvue d'un moyen d'accroche périphérique permettant sa fixation sur une lisse, la toile ajourée et la toile pleine étant assemblées l'une et l'autre sur ledit moyen d'accroché périphérique.Advantageously, the web is provided with a peripheral attachment means allowing it to be attached to a rail, the perforated fabric and the solid fabric being assembled together on said peripheral attachment means.

Avantageusement, les toiles sont soudées entre elles au niveau du moyen d'accroche.Advantageously, the fabrics are welded together at the attachment means.

Avantageusement, l'une des toiles comporte des micro-perforations arrangées pour former, avec l'autre toile, une nappe acoustique.Advantageously, one of the fabrics has micro-perforations arranged to form, with the other fabric, an acoustic layer.

L'invention concerne également un faux plafond comprenant une nappe souple telle que décrite précédemment, fixée tendue sur au moins une lisse, la toile ajourée étant disposée du côté opposé à l'intérieur du local dans lequel le faux-plafond est aménagé.The invention also relates to a false ceiling comprising a flexible web as described above, fixed taut on at least one rail, the perforated fabric being arranged on the opposite side inside the room in which the false ceiling is arranged.

Avantageusement, le faux plafond comporte des moyens lumineux disposés au dessus de la toile ajourée.Advantageously, the false ceiling comprises luminous means arranged above the perforated canvas.

D'autres objets et avantages de l'invention apparaîtront au cours de la description qui suit, faite en référence aux dessins annexés, dans lesquels :

  • la figure 1 représente une vue schématique partielle en coupe d'un faux plafond équipé d'une nappe souple selon l'invention ;
  • la figure 2 représente une vue éclatée de la nappe illustrée sur la figure 1.
Other objects and advantages of the invention will appear during the following description, made with reference to the appended drawings, in which:
  • the figure 1 shows a partial schematic sectional view of a false ceiling equipped with a flexible sheet according to the invention;
  • the figure 2 shows an exploded view of the cable shown in the figure 1 .

DESCRIPTION DETAILLEE DES FIGURESDETAILED DESCRIPTION OF FIGURES

En relation avec les figures 1 et 2, il est décrit un faux plafond 1, du type faux plafond tendu, équipé d'une nappe souple 2 selon l'invention accrochée tendue sur des lisses 3 fixées sur les parois murales 4 d'un local. Les lisses 3 forment avec la nappe 2 une structure fermée avantageusement étanche.In relation to the figures 1 and 2 , there is described a false ceiling 1, of the stretched false ceiling type, equipped with a flexible sheet 2 according to the invention hung stretched on smooth 3 fixed to the wall walls 4 of a room. The heddles 3 form with the ply 2 a closed structure which is advantageously sealed.

La nappe 2 est constituée de deux toiles 3, 4, avantageusement en polychlorure de vinyle, superposées et assemblées en périphérie sur un moyen d'accroche 5. Dans l'exemple illustré sur la figure 1, le moyen d'accroche 5 présente une forme de harpon 6 lequel coopère avec l'épaulement d'accroché 7 des lisses 3 prévu à cet effet. Avantageusement, les deux toiles 3, 4 sont assemblées par soudage. Selon un mode de réalisation particulier, les deux toiles 3, 4 sont assemblées en premier lieu entre elles en périphérie, pour être en deuxième lieu fixées au moyen d'accroche 5. Selon un autre mode de réalisation, les toiles 3, 4 sont fixées indépendamment l'une de l'autre au moyen d'accroche 5. Avantageusement, l'assemblage des toiles 3, 4 entre elles et l'assemblage des toiles 3, 4 sur le moyen d'accroche 5 est réalisé par soudage. L'assemblage peut bien entendu être réalisé par tout autre moyen de fixation connu, tel que le collage.The sheet 2 consists of two fabrics 3, 4, advantageously made of polyvinyl chloride, superimposed and assembled at the periphery on a means of attachment 5. In the example illustrated in the figure 1 , the attachment means 5 has the shape of a harpoon 6 which cooperates with the attachment shoulder 7 of the heddles 3 provided for this purpose. Advantageously, the two fabrics 3, 4 are assembled by welding. According to a particular embodiment, the two fabrics 3, 4 are firstly assembled together at the periphery, to be secondly fixed to the attachment means 5. According to another embodiment, the fabrics 3, 4 are fixed independently of each other by means of attachment 5. Advantageously, the assembly of the fabrics 3, 4 between them and the assembly of the fabrics 3, 4 on the means of attachment 5 is carried out by welding. The assembly can of course be achieved by any other known fixing means, such as gluing.

Dans le mode de réalisation illustré, la toile disposée au-dessus, i.e., du côté opposé au côté visible depuis l'intérieur du local, est une toile ajourée, avantageusement opaque, tandis que la toile disposée en-dessous, i.e. disposée du côté visible depuis l'intérieur du local, est une toile pleine, c'est-à-dire sans zone évidée, avantageusement opaque. La figure 2 montre une vue éclatée de la nappe 2. La toile pleine 4 disposée sous la toile ajourée 3, recouvre ainsi les zones évidées 30 de la toile ajourée 3. La toile pleine 4 disposée au-dessous assure ainsi l'étanchéité à l'air, à la poussière ou autres résidus. Dans l'exemple illustré, les zones évidées ont la forme de carrés. Il est bien entendu évident que l'invention ne se limite pas à cette forme des zones ajourées, et qu'il peut être prévu toutes autres formes ou combinaisons de formes mais également toutes autres dispositions des zones ajourées sans sortir du cadre de l'invention, la forme et la répartition étant choisies en fonction des motifs visuels recherchés pour le faux-plafond.In the illustrated embodiment, the canvas arranged above, ie, on the side opposite the side visible from inside the room, is an openwork canvas, advantageously opaque, while the canvas arranged below, ie arranged on the side visible from inside the room, is a solid canvas, that is to say without a recessed area, advantageously opaque. The figure 2 shows an exploded view of the ply 2. The solid fabric 4 placed under the perforated fabric 3, thus covers the recessed areas 30 of the perforated fabric 3. The full fabric 4 placed below thus ensures the airtightness, dust or other residue. In the example shown, the recessed areas have the shape of squares. It is of course obvious that the invention is not limited to this form of the perforated zones, and that it can be provided all other shapes or combinations of shapes but also any other arrangements of the perforated zones without departing from the scope of the invention, the shape and the distribution being chosen according to the visual patterns sought for the false ceiling.

Les deux toiles 3, 4 ont été représentées sur la figure 1 avec un léger écartement entre elles, ceci afin de montrer le nombre de toiles constituant la nappe 2. Les deux toiles 3, 4 sont cependant superposées, c'est-à-dire en contact l'une de l'autre. Afin d'assurer le plaquage des toiles 3, 4 l'une contre l'autre, la toile du dessus présente un grammage supérieur à celui de la toile du dessous de sorte que lorsque la nappe 2 est fixée tendue sur les lisses, la toile du dessus, en l'espèce la toile ajourée 3, repose sur la toile pleine 4. Le rapport de poids entre la toile ajourée 3 et la toile pleine 4 devra être défini pour éviter un fléchissement de la toile de dessous sous la masse de la toile de dessus.The two canvases 3, 4 have been represented on the figure 1 with a slight distance between them, in order to show the number of fabrics constituting the web 2. The two fabrics 3, 4 are however superposed, that is to say in contact with one another. In order to ensure the pressing of the fabrics 3, 4 against each other, the top fabric has a weight greater than that of the bottom fabric so that when the web 2 is fixed taut on the smooth, the fabric top, in this case the perforated canvas 3, rests on the solid canvas 4. The weight ratio between the perforated canvas 3 and the solid canvas 4 will have to be defined to avoid a bending of the canvas below under the mass of the top canvas.

Afin d'améliorer les performances acoustiques du local dans lequel le faux-plafond est disposé, l'une des toiles 3, 4 comporte des micro-perforations 40 arrangées et distribuées de façon à former une toile absorbant acoustiquement les sons. Par micro-perforations 40, on entend toutes perforations ayant un diamètre inférieur ou égal à 2 millimètres. La présence d'une toile micro-perforée a pour avantage d'augmenter de manière significative les performances acoustiques de la structure 1. Avantageusement, les micro-perforations 40 sont prévues sur la toile disposée du côté visible depuis l'intérieur du local, à savoir, dans l'exemple illustré, sur la toile pleine 4.In order to improve the acoustic performance of the room in which the false ceiling is arranged, one of the fabrics 3, 4 comprises micro-perforations 40 arranged and distributed so as to form a fabric that acoustically absorbs sound. By micro-perforations 40 is meant any perforation having a diameter less than or equal to 2 millimeters. The presence of a micro-perforated canvas has the advantage of significantly increasing the acoustic performance of the structure 1. Advantageously, the micro-perforations 40 are provided on the canvas arranged on the side visible from inside the room, namely, in the example shown, on the full canvas 4.

Dans l'exemple illustré, le faux-plafond est un faux-plafond lumineux. Pour ce faire, des moyens lumineux 8 sont disposés au dessus de la nappe 2, dans l'espace 9 délimité par le plafond 10 et la nappe 2 tendue. Ils sont fixés sur le plafond 10. Ainsi, la lumière en provenance des moyens lumineux 8 passe au travers des zones ajourées 30 de la toile opaque du dessus et des parties de la toile translucide situées sous les zones ajourées 30 et en regard de celles-ci, réalisant ainsi un faux-plafond offrant des motifs visuels correspondant à la forme des zones ajourées prévues, sans que ces derniers ne soient flous du fait du parfait placage des toiles 3, 4 entre elles.In the example shown, the false ceiling is a luminous false ceiling. To do this, light means 8 are arranged above the sheet 2, in the space 9 delimited by the ceiling 10 and the stretched sheet 2. They are fixed on the ceiling 10. Thus, the light coming from the luminous means 8 passes through the perforated zones 30 of the opaque canvas above and the parts of the translucent canvas located under the perforated zones 30 and opposite those. ci, thus producing a false ceiling offering visual patterns corresponding to the shape of the openwork areas provided, without the latter being blurred due to the perfect veneer of the canvases 3, 4 between them.

Dans ce qui précède, il a été décrit un faux-plafond à toile tendue. Il est bien entendu évident que la nappe selon l'invention peut être également mise en oeuvre pour la réalisation d'un faux-plafond suspendu ou bien d'un caisson pour plafond.In the above, a stretched canvas false ceiling has been described. It is of course obvious that the sheet according to the invention can also be implemented for the production of a suspended false ceiling or else of a box for a ceiling.

L'invention est décrite dans ce qui précède à titre d'exemple. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de réalisation de l'invention sans pour autant sortir du cadre de l'invention tel que défini par les revendications annexées.The invention is described in the foregoing by way of example. It is understood that a person skilled in the art is able to produce different variant embodiments of the invention without departing from the scope of the invention as defined by the appended claims.
