Description

Domaine techniqueTechnical area

La présente invention concerne une structure poussante apte à créer un relief et destinée à être intégrée à une fausse paroi, telles que, par exemple, les faux plafonds et les faux murs et en particulier ceux constitués par au moins une nappe souple tendue accrochée le long de ses bords à un support fixé aux murs ou au plafond d'un local dans un bâtiment.The present invention relates to a pushing structure capable of creating a relief and intended to be integrated into a false wall, such as, for example, false ceilings and false walls and in particular those constituted by at least one stretched flexible sheet hung along from its edges to a support fixed to the walls or ceiling of a room in a building.

Technique antérieurePrior art

On connaît déjà des fausses parois qui comprennent d'une part un cadre périphérique fixé aux murs ou au plafond d'un local, ce cadre étant formé par une lisse extérieure constituée elle-même de profilés aboutés, et d'autre part, une nappe souple tendue à l'intérieur de ce cadre. Cette nappe souple est le plus souvent constituée par une toile de matériaux polymères présentant de nombreuses qualités telles que notamment : résistance au feu, étanchéité à l'air comme à la poussière ou à l'humidité, facilité d'entretien, etc.False walls are already known which comprise on the one hand a peripheral frame fixed to the walls or to the ceiling of a room, this frame being formed by an outer rail itself consisting of abutting profiles, and on the other hand, a tablecloth soft stretched inside this frame. This flexible sheet is most often constituted by a fabric of polymeric materials having many qualities such as including: fire resistance, airtightness as dust or moisture, ease of maintenance, etc..

Ce type de fausses parois connues repose sur le principe d'une mise sous tension de la nappe souple sur le cadre, de manière parfaitement plane, horizontalement ou verticalement selon qu'il s'agisse d'un faux plafond ou d'un faux mur. Ladite nappe souple est maintenue tendue du fait de l'accrochage, sur la lisse, d'une bordure solidaire de la nappe formant un harpon. Cette nappe 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 par exemple les poussières dans ce plénum.This type of known false walls is based on the principle of a power of the flexible sheet on the frame, perfectly flat, horizontally or vertically depending on whether it is a false ceiling or a false wall . Said flexible sheet is kept taut because of the attachment, on the rail, of a border integral with the web forming a harpoon. This sheet is thus stretched parallel to a wall of the room so as to leave a residual space located 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. Therefore, said canvas can hide these equipment but also the imperfections of the walls of the room and to have a uniform and clean visible surface by retaining for example the dust in this plenum.

Par ailleurs, ces fausses parois comportent parfois des éléments en relief, tels que décrit dans US 4724181 A1 , lesdits éléments comprennent classiquement des faces adjacentes non coplanaires, tels que des caissons, qui peuvent être disposés pour éclairer la pièce ou à des fins décoratives.Moreover, these false walls sometimes comprise elements in relief, as described in US 4724181 A1 said elements conventionally comprise non-coplanar adjacent faces, such as boxes, which can be arranged to illuminate the room or for decorative purposes.

Ainsi, on connaît des caissons lumineux de ce type, aptes à être intégrés à un faux plafond, de forme globalement parallélépipédique, comprenant une pluralité de sources de lumière fixées au plafond et situées à l'intérieur de quatre faces verticales adjacentes non coplanaires fixées sur ledit plafond et une nappe souple avantageusement translucide recouvrant au moins sa face inférieure horizontale ouverte.Thus, there are known light boxes of this type, able to be integrated into a false ceiling, of generally parallelepipedal shape, comprising a plurality of light sources fixed to the ceiling and located inside four adjacent non-coplanar vertical faces fixed on said ceiling and a preferably translucent flexible sheet covering at least its horizontal open bottom face.

L'un des inconvénients de ce type de caissons lumineux ou non est qu'ils nécessitent la mise en place d'une ossature structurelle coûteuse, difficile à mettre en oeuvre pour réaliser notamment les faces adjacentes non coplanaires desdits caissons.One of the disadvantages of this type of light boxes or not is that they require the establishment of an expensive structural framework, difficult to implement to achieve in particular the non-coplanar adjacent faces of said boxes.

Un autre inconvénient est que ladite ossature structurelle permet difficilement d'obtenir des surfaces gauches telles que notamment des calottes sphériques ou ovoïdales ou encore des faces en forme générale de demi-hyperboles.Another disadvantage is that said structural framework makes it difficult to obtain left surfaces such as in particular spherical or ovoidal caps or faces generally in the form of half-hyperbolas.

Enfin, un autre inconvénient de ce type de caissons lumineux connus est que des poussières ou divers résidus contenus dans le plénum entre la paroi du local et le faux plafond peuvent tomber sur la nappe translucide. Ainsi, lorsque les sources de lumières sont allumées, lesdites poussières ou résidus apparaissent alors comme des tâches noires sur la nappe translucide rendant le caisson particulièrement inesthétique.Finally, another drawback of this type of known light boxes is that dust or various residues contained in the plenum between the wall of the room and the false ceiling can fall on the translucent sheet. Thus, when the light sources are on, said dust or residue then appear as black spots on the translucent sheet making the box particularly unsightly.

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 structure poussante d'une nappe souple destinée à créer un relief pérenne et à être intégrée à une fausse paroi, ladite structure étant simple, économique et en mesure de satisfaire à l'ensemble des contraintes et conditions précitées.The object of the present invention is therefore to overcome the aforementioned drawbacks and to provide a pushing structure of a flexible sheet intended to create a perennial relief and to be integrated into a false wall, said structure being simple, economical and able to satisfy all the constraints and conditions mentioned above.

Conformément à l'invention, il est donc proposé une structure poussante apte à créer un relief et destinée à être intégrée à tout ou partie d'une fausse paroi, notamment un faux plafond, remarquable en ce qu'elle comporte un premier châssis, au moins une première nappe souple, dite externe, comprenant une toile extensible et un moyen d'accrochage fixé à la périphérie de ladite toile et permettant la fixation de ladite première nappe souple sur ledit premier châssis, au moins un élément entretoise et un second châssis maintenu à distance du premier châssis par l'élément entretoise et apte à mettre en relief la toile de la première nappe souple.According to the invention, it is therefore proposed a pushing structure capable of creating a relief and intended to be integrated in all or part of a false wall, including a false ceiling, remarkable in that it comprises a first frame, the less a first flexible sheet, said external, comprising an extensible fabric and a fastening means attached to the periphery of said fabric and allowing the attachment of said first flexible sheet on said first frame, at least one spacer element and a second frame maintained remote from the first frame by the spacer element and adapted to highlight the web of the first flexible web.

Selon un mode de réalisation préférentiel, le premier châssis est constitué par une lisse formant un cadre fermé.According to a preferred embodiment, the first frame is constituted by a smooth forming a closed frame.

De manière avantageuse, ledit second châssis est de préférence en forme de cadre fermé.Advantageously, said second frame is preferably in the form of a closed frame.

Selon un mode de réalisation avantageux, le moyen d'accrochage périphérique de la première nappe souple est un harpon présentant une forme de crochet et est apte à coopérer avec la lisse du premier châssis.According to an advantageous embodiment, the peripheral fastening means of the first flexible sheet is a harpoon having a hook shape and is adapted to cooperate with the first frame of the beam.

On comprend bien qu'en utilisant un type de structure conforme à l'invention, il est possible de créer un relief esthétique lumineux en mettant en place derrière la nappe souple externe des sources lumineuses disposées dans le plénum et en choisissant ladite nappe souple externe translucide.It is understood that by using a type of structure according to the invention, it is possible to create a luminous aesthetic relief by placing light sources arranged in the plenum behind the outer flexible ply and by choosing said translucent outer flexible ply. .

Selon une seconde variante de réalisation, la structure comprend avantageusement une nappe souple interne disposée derrière la nappe souple externe et devant des sources lumineuses installées dans le plénum, ladite nappe souple interne étant de préférence transparente. Ainsi, cette dernière permet d'isoler la nappe souple externe des poussières ou résidus afin que ces derniers n'apparaissent pas comme des tâches noires sur ladite nappe souple externe translucide.According to a second variant embodiment, the structure advantageously comprises an internal flexible ply disposed behind the outer flexible ply and in front of light sources installed in the plenum, the said internal flexible ply preferably being transparent. Thus, the latter makes it possible to isolate the outer flexible sheet of dust or residue so that the latter do not appear as black spots on said translucent outer flexible sheet.

Enfin, la structure poussante conforme à l'invention pourra être utilisée soit de façon indépendante, soit en juxtaposition avec des structures semblables pour créer une fausse paroi obtenue à partir d'un réseau de reliefs, ou encore soit en intégration à tout ou partie d'une fausse paroi du type à nappe souple tendue disposée le long d'une paroi d'un local.Finally, the pushing structure according to the invention may be used either independently or in juxtaposition with similar structures to create a false wall obtained from a network of reliefs, or else in integration with all or part of a false wall of the stretched flexible sheet type disposed along a wall of a room.

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

On décrira dans cette variante d'exécution préférentielle non limitative, une structure poussante employée pour la réalisation d'un relief dans un faux plafond ; toutefois, la structure poussante peut évidemment être utilisée pour un faux mur, voire également pour former un panneau, un écran ou une fausse paroi faisant office de support publicitaire par exemple.In this non-limiting preferred embodiment variant, a pushing structure used for producing a relief in a false ceiling will be described; However, the pushing structure can obviously be used for a false wall, or even to form a panel, a screen or a false wall serving as an advertising medium for example.

En référence à la figure 1, la fausse paroi, de type faux plafond tendu, comprend une nappe souple 1 tendue horizontalement en partie haute du local 2 de sorte à laisser un plénum 3 situé entre le plafond 4 dudit local 2 et ladite fausse paroi 1. Ledit plénum 3 permet notamment de loger tous les équipements inesthétiques tels que des câbles électriques, des tuyauteries, etc.With reference to the figure 1 , the false wall, false suspended ceiling type, comprises a flexible sheet 1 stretched horizontally in the upper part of the room 2 so as to leave a plenum 3 located between the ceiling 4 of said room 2 and said false wall 1. Said plenum 3 allows including to house all unsightly equipment such as electrical cables, pipes, etc.

En référence aux figures 1 à 4, ladite fausse paroi comprend une structure poussante 5, conforme à l'invention, comportant un premier châssis 6, au moins une première nappe souple 7 dite externe comprenant une toile 71 avantageusement extensible et un moyen d'accrochage 8 fixé à la périphérie de ladite toile 71 et permettant la fixation de ladite première nappe souple 7 sur ledit premier châssis 6, un second châssis 9 et au moins un élément entretoise 10 pour maintenir à distance le second châssis 9 du premier châssis 6 et mettre en relief la toile 71 de la première nappe souple 7.With reference to Figures 1 to 4 said false wall comprises a pushing structure 5, according to the invention, comprising a first frame 6, at least a first so-called outer flexible ply 7 comprising a fabric 71 advantageously extensible and a fastening means 8 fixed to the periphery of said web 71 and allowing the attachment of said first flexible ply 7 to said first frame 6, a second frame 9 and at least one spacer element 10 to keep the second frame 9 of the first frame 6 at a distance and to highlight the canvas 71 of the first flexible ply 7.

Le premier châssis 6 est constitué par une lisse 11 formant un cadre fermé, constituée elle-même de profilés aboutés et fixée au plafond 4 du local 2 par des moyens appropriés, non représentés, tels que des vis. Ledit premier châssis 6 est de préférence plan et en forme de polygone comportant au moins trois sommets. Dans la variante d'exécution représentée sur les figures 2 et 3, le premier châssis 6 est en forme d'hexagone régulier. L'Homme du Métier pourra concevoir un premier châssis 6 de forme différente procurant les mêmes effets, telle que par exemple une forme circulaire, elliptique ou encore non plane, sans sortir du cadre de la présente invention.The first frame 6 is constituted by a smooth 11 forming a closed frame, itself consisting of abutting profiles and fixed to the ceiling 4 of the room 2 by appropriate means, not shown, such as screws. Said first frame 6 is preferably plane and shaped polygon with at least three vertices. In the execution variant represented on the Figures 2 and 3 , the first frame 6 is in the form of a regular hexagon. The skilled person may design a first frame 6 of different shape providing the same effects, such as for example a circular, elliptical or non-planar, without departing from the scope of the present invention.

En outre, la lisse 11 peut, par exemple, prendre la forme de celle représentée sur les figures et en particulier la figure 4. Ainsi, la lisse 11 comprend au moins une aile verticale externe 111, qui s'étend de préférence perpendiculairement au plafond 4 du local 2. De cette aile verticale externe 111 est issue, à peu près à mi-hauteur, une âme horizontale supérieure 112 s'étendant sur une faible distance en direction de la première nappe souple 7. Cette âme horizontale supérieure 112 rejoint, à son extrémité, une aile verticale interne 113 s'étendant vers le local 2 un peu plus bas que l'aile verticale externe 111, c'est-à-dire que l'aile verticale interne 113 est un peu plus basse que l'aile verticale externe 111 et que la face externe 114 de la lisse 11 qui se trouve à l'opposé du plafond 4. Cette aile verticale externe 111 présente, à son extrémité inférieure, un épaulement 115 s'étendant perpendiculairement à ladite aile verticale externe 111 vers la première nappe souple 7, sur une faible distance.In addition, the beam 11 may, for example, take the form of that shown in the figures and in particular the figure 4 . Thus, the beam 11 comprises at least one vertical outer wing 111, which preferably extends perpendicularly to the ceiling 4 of the room 2. This outer vertical wing 111 is issued, at about halfway up, an upper horizontal web 112 extending at a short distance towards the first flexible ply 7. This upper horizontal core 112 joins, at its end, an inner vertical flange 113 extending towards the room 2 a little lower than the external vertical flange 111 , that is to say that the inner vertical wing 113 is a little lower than the outer vertical wing 111 and the outer face 114 of the beam 11 which is opposite the ceiling 4. This wing External vertical 111 has, at its lower end, a shoulder 115 extending perpendicularly to said outer vertical flange 111 to the first flexible ply 7, over a short distance.

Afin de ne pas détériorer la première nappe souple 7 et son moyen d'accrochage 8 périphérique, l'aile verticale interne 113 et l'épaulement 115 présentent avantageusement une extrémité arrondie.In order not to damage the first flexible ply 7 and its peripheral fastening means 8, the inner vertical flange 113 and the shoulder 115 advantageously have a rounded end.

La partie inférieure de l'aile verticale externe 111, l'âme horizontale supérieure 112, l'aile verticale interne 113 et l'épaulement 115 déterminent un évidement 116 ouvert vers le local 2 et dans lequel peut être engagé le moyen d'accrochage 8 périphérique de la première nappe souple 7.The lower part of the outer vertical wing 111, the upper horizontal web 112, the inner vertical wing 113 and the shoulder 115 determine a recess 116 open towards the room 2 and in which can the peripheral fastening means 8 of the first flexible ply 7 are engaged.

Ledit moyen d'accrochage 8 périphérique de la première nappe souple 7 est, par exemple, un harpon présentant une forme de crochet apte à coopérer avec la lisse 11 du premier châssis 6. Il comprend une branche interne 81 par laquelle il est relié à la toile 71 de la première nappe souple 7 et une branche externe 82 en forme de bourrelet à l'extrémité arrondie recourbée vers le bas. Lesdites branches interne et externe 81, 82 sont avantageusement issues de matière.Said gripping means 8 peripheral of the first flexible ply 7 is, for example, a harpoon having a hook shape adapted to cooperate with the smooth 11 of the first frame 6. It comprises an inner branch 81 by which it is connected to the web 71 of the first flexible ply 7 and an outer branch 82 in the form of a bead with the rounded end bent downwards. Said inner and outer branches 81, 82 are advantageously made of material.

Ledit moyen d'accrochage 8 prend appui, lorsque la première nappe souple 7 est tendue, sur l'épaulement 115 par l'extrémité inférieure de sa branche externe 82.Said attachment means 8 bears, when the first flexible ply 7 is stretched, on the shoulder 115 by the lower end of its outer branch 82.

La lisse 11 décrite ci-dessus n'est qu'une variante d'exécution préférentielle et l'Homme du Métier pourra concevoir une lisse 11 de forme différente procurant les mêmes effets sans sortir du cadre de la présente invention.The arm 11 described above is only a variant of preferred embodiment and the skilled person can design a smooth 11 of different shape providing the same effects without departing from the scope of the present invention.

D'autres lisses sont, par exemple, décrites dans le brevet FR 2 630 476 .Other smooth are, for example, described in the patent FR 2 630 476 .

Le second châssis 9 est de préférence en forme de cadre fermé, formé par des profilés 91 aboutés. Ces profilés 91 sont avantageusement des profilés extrudés de section carrée, rectangulaire ou encore ronde réalisés en alliage léger tel que par exemple un alliage d'aluminium. Ledit second châssis 9 est de préférence plan et en forme de polygone comportant au moins trois sommets. Dans la variante d'exécution représentée sur les figures 2 et 3, le second châssis 9 est en forme d'hexagone régulier. L'Homme du Métier pourra concevoir un second châssis 9 de forme différente procurant les mêmes effets, telle que par exemple une forme circulaire, elliptique, non plane ou encore non fermée, sans sortir du cadre de la présente invention.The second frame 9 is preferably in the form of a closed frame, formed by abutting profiles 91. These profiles 91 are advantageously extruded sections of square, rectangular or round section made of light alloy such as for example an aluminum alloy. Said second frame 9 is preferably plane and in the form of a polygon having at least three vertices. In the execution variant represented on the Figures 2 and 3 the second frame 9 is in the form of a regular hexagon. The skilled person may design a second frame 9 of different shape providing the same effects, such as for example a circular, elliptical, non-planar or not closed, without departing from the scope of the present invention.

La structure poussante 5, conforme à l'invention, comprend en outre au moins un élément entretoise 10 pour maintenir à distance le second châssis 9 du premier châssis 6 et mettre en relief la toile 71 de la première nappe souple 7.The pushing structure 5, according to the invention, further comprises at least one spacer element 10 for keeping the second frame 9 of the first frame 6 at a distance and to highlight the web 71 of the first flexible sheet 7.

Dans la variante d'exécution préférentielle représentée sur la figure 3, la structure poussante 5 comprend deux éléments entretoises 10 parallèles entre eux et s'étendant dans un plan perpendiculaire au premier châssis 6 et comportant une traverse 101 avantageusement disposée à l'intérieur du premier châssis 6 et joignant deux de ses cotés opposés, et deux pieds 102 issus perpendiculairement de ladite traverse 101 et joignant le second châssis 9. Les deux pieds 102 d'un élément entretoise 10 sont solidaires du second châssis 9 en deux de ses sommets opposés. Par ailleurs, les deux éléments entretoises 10 sont parallèles entre eux et sont avantageusement des profilés extrudés de section carrée, rectangulaire ou encore ronde réalisés en alliage léger tel que par exemple un alliage d'aluminium.In the preferred embodiment variant represented on the figure 3 , the pushing structure 5 comprises two spacer elements 10 parallel to each other and extending in a plane perpendicular to the first frame 6 and having a cross member 101 advantageously arranged inside the first frame 6 and joining two of its opposite sides, and two feet 102 perpendicularly from said cross member 101 and joining the second frame 9. The two feet 102 of a spacer element 10 are integral with the second frame 9 in two of its opposite peaks. Furthermore, the two spacer elements 10 are parallel to each other and are advantageously extruded sections of square, rectangular or round section made of light alloy such as for example an aluminum alloy.

En référence aux figures 2 et 3, le second châssis 9 est incliné d'environ 15° par rapport au premier châssis 6. Ainsi, pour obtenir ladite inclinaison, les deux pieds 102 d'un des deux éléments entretoises 10 sont plus courts que ceux de l'autre élément entretoise 10. Il va de soi que la longueur de chaque pied 102 des éléments entretoises 10 pourra être individuellement ou non adaptée en fonction de la direction et la valeur de l'angle d'inclinaison.With reference to Figures 2 and 3 the second frame 9 is inclined at approximately 15 ° with respect to the first frame 6. Thus, to obtain said inclination, the two legs 102 of one of the two spacer elements 10 are shorter than those of the other spacer element 10 It goes without saying that the length of each leg 102 of the spacer elements 10 can be individually or non-adapted depending on the direction and the value of the angle of inclination.

De même, on comprend bien que l'on pourra adapter le nombre, la forme et les dimensions des éléments entretoises 10 notamment en fonction de la forme et des dimensions des premier et second châssis 6, 9 , sans aucune difficulté et sans sortir du cadre de la présente invention.Similarly, it is clear that we can adapt the number, shape and dimensions of the spacer elements 10 in particular according to the shape and dimensions of the first and second frame 6, 9, without any difficulty and without departing from the scope of the present invention.

Ainsi, les traverses 101 pourront être disposées à l'intérieur du second châssis 9 ou encore les éléments entretoises 10 pourront ne comporter aucune traverse 101 ou une traverse 101 prévue à l'intérieur de chacun des premier et second châssis 6, 9.Thus, the cross members 101 may be disposed inside the second frame 9 or the spacer members 10 may have no cross member 101 or a cross member 101 provided inside each of the first and second frame 6, 9.

En référence aux figures 1 et 2, lorsque les premier et second châssis 6, 9 et les éléments entretoises 10 sont assemblés entre eux, la nappe souple 6 est placée sur l'ensemble ainsi constitué en recouvrant le second châssis 9 de sa toile 71 et en se fixant sur le premier châssis 6 par le biais de son moyen d'accrochage 8 périphérique, comme décrit précédemment. On voit bien que la nappe souple 7 se trouve tendue et forme alors un relief tel que celui représenté sur la figure 2.With reference to Figures 1 and 2 when the first and second frames 6, 9 and the spacer elements 10 are assembled together, the flexible sheet 6 is placed on the assembly thus formed by covering the second frame 9 with its fabric 71 and attaching itself to the first frame 6 through its peripheral attachment means 8, as described above. It can clearly be seen that the flexible sheet 7 is stretched and then forms a relief such as that represented on FIG. figure 2 .

Pour obtenir une tension homogène, on comprend bien que la toile 71 de la nappe 7 doit être extensible et que la nappe 7 ne doit pas avoir de dimensions trop importantes. Ainsi, la nappe 7 aura une forme homothétique à celle du premier châssis 6 et des dimensions réduites d'environ 1% par rapports à celles dudit premier châssis 6.To obtain a homogeneous tension, it is well understood that the web 71 of the web 7 must be extensible and that the web 7 must not have too large dimensions. Thus, the ply 7 will have a homothetic shape to that of the first frame 6 and dimensions reduced by about 1% compared to those of said first frame 6.

Compte tenu des formes de la structure poussante 5, le taux de réduction des dimensions de la nappe souple 7 est plus petit que celui employé pour une nappe souple utilisée pour réaliser une fausse paroi plane, ce taux étant classiquement de 7%.Taking into account the shapes of the pushing structure 5, the reduction rate of the dimensions of the flexible sheet 7 is smaller than that used for a flexible sheet used to make a false flat wall, this ratio being conventionally 7%.

Comme représenté sur la figure 2, le relief obtenu par la structure poussante 5 est particulièrement esthétique car la nappe souple 7 comporte des faces latérales gauches.As shown on the figure 2 , the relief obtained by the pushing structure 5 is particularly aesthetic because the flexible sheet 7 has left side faces.

En référence à la figure 1, la structure poussante 5 selon l'invention peut être également employée comme caisson lumineux en lui associant des sources lumineuses 12 disposées dans le plénum 3 et en utilisant une nappe souple 7 avec une toile 71 translucide ou transparente.With reference to the figure 1 the pushing structure 5 according to the invention can also be used as a light box by associating it with light sources 12 arranged in the plenum 3 and by using a flexible sheet 7 with a translucent or transparent fabric 71.

Enfin, on comprend bien que la structure poussante 5 selon l'invention pourra être utilisée soit en intégration à toute ou partie d'une fausse paroi du type par exemple faux-plafond tendu disposée le long d'un plafond 4 d'un local 2, comme décrit précédemment, soit de façon indépendante, soit en juxtaposition avec des structures semblables pour créer une fausse paroi obtenue à partir d'un réseau de reliefs. Dans le cas d'une utilisation indépendante, on pourra également placer deux structures poussantes 5 dos à dos pour former un volume complet faisant office de support publicitaire par exemple.Finally, it is well understood that the pushing structure 5 according to the invention can be used either in integration with all or part of a false wall of the type for example false ceiling stretched along a ceiling 4 of a room 2 , as previously described, either independently or in juxtaposition with similar structures to create a false wall obtained from a network of reliefs. In the case of independent use, one can also place two push structures back to back to form a complete volume serving as advertising medium for example.

Description d'autres modes de réalisationDescription of other embodiments

Dans une variante de réalisation représentée sur la figure 5, la structure poussante 5 comporte une deuxième nappe souple 13, dite interne, comprenant un moyen d'accrochage périphérique non représenté permettant la fixation de ladite deuxième nappe souple 13 sur le premier châssis 6, ladite deuxième nappe souple 13 étant disposée derrière la première nappe souple 7 externe et devant des sources lumineuses 12 installées dans le plénum 3. Ladite deuxième nappe souple 13 interne est de constitution semblable à celle de la première nappe souple 7 et de préférence transparente.In an alternative embodiment shown on the figure 5 the pushing structure 5 comprises a second flexible sheet 13, called internal, comprising a not shown peripheral fastening means for fixing said second flexible sheet 13 to the first frame 6, said second flexible sheet 13 being disposed behind the first sheet flexible outer 7 and in front of light sources 12 installed in the plenum 3. Said second internal flexible ply 13 is of similar constitution to that of the first flexible ply 7 and preferably transparent.

On désigne ici par "devant" la zone située du coté du local 2 et par "derrière" la zone située du coté opposé audit local 2.Here is designated by "in front" the area located on the side of the room 2 and "behind" the area on the side opposite said room 2.

Cette configuration évite que les poussières ou résidus présents dans ledit plénum 3 n'apparaissent comme des tâches noires sur ladite première nappe souple externe translucide. En effet, la deuxième nappe souple 13 permet d'isoler la première nappe souple 7 externe desdits poussières ou résidus.This configuration prevents the dust or residues present in said plenum 3 from appearing as black spots on said first translucent outer flexible ply. Indeed, the second flexible ply 13 makes it possible to isolate the first flexible ply 7 external said dust or residue.

Selon une autre variante de réalisation non représentée, le second châssis 9 comporte un organe de forme supplémentaire par exemple de type arceau reliant deux sommets opposés dudit second châssis 9 et permettant de donner un relief supplémentaire.According to another embodiment variant not shown, the second frame 9 comprises a further form member for example of the hoop type connecting two opposite peaks of said second frame 9 and to give an additional relief.

Enfin, selon une autre variante de réalisation dite "extrême" non représentée et ne faisant pas partie de la présente invention, la structure poussante 5 ne comporte pas de second châssis. La première nappe souple est toujours fixée sur le premier châssis par l'intermédiaire du moyen d'accrochage fixé à la périphérie de sa toile et est alors mise en relief uniquement par au moins l'élément entretoise. Ainsi, avec un élément entretoise tel que celui décrit précédemment, la première nappe souple est alors mise en relief par l'extrémité libre des pieds de l'élément entretoise. On comprend bien que dans cette configuration, l'extrémité libre des pieds dudit élément entretoise est de préférence arrondie afin d'éviter toute altération de la toile de la première nappe souple lors de la mise en relief. Toutefois, dans cette variante de réalisation "extrême", la nappe souple peut être endommagée lors de la mise en relief de la toile, car l'élément entretoise est généralement saillant et risque de perforer ladite toile.Finally, according to another alternative embodiment called "extreme" not shown and not part of the present invention, the push structure 5 has no second frame. The first flexible ply is always fixed on the first frame by means of the fastening means attached to the periphery of its fabric and is then raised only by at least the spacer element. Thus, with a spacer element such as that described above, the first flexible sheet is then raised by the free end of the feet of the spacer element. It is understood that in this configuration, the free end of the feet of said spacer element is preferably rounded to prevent any alteration of the web of the first flexible web during the relief. However, in this "extreme" embodiment variant, the flexible sheet may be damaged during the embossment of the fabric, because the spacer element is generally projecting and may perforate said fabric.

Possibilité d'application industriellePossibility of industrial application

La structure poussante 5 selon l'invention est principalement destinée à être utilisée en intégration à tout ou partie d'une fausse paroi dans tout type de local de préférence industriel et quelque soit l'orientation de ladite fausse-paroi. En outre, il ressort clairement de la description que la structure poussante 5 selon l'invention est de construction légère et simple et qu'elle permet d'obtenir simplement de nombreuses formes de relief.The pushing structure 5 according to the invention is mainly intended to be used in integration with all or part of a false wall in any type of premises preferably industrial and whatever the orientation of said false-wall. In addition, it is clear from the description that the push structure 5 according to the invention is light and simple construction and that it allows to simply obtain many forms of relief.

Enfin, il va de soi que les exemples de structure poussante 5 conforme à l'invention qui viennent d'être décrits ne sont que des illustrations particulières, en aucun cas limitatives de l'invention.Finally, it goes without saying that the examples of push structure 5 according to the invention which have just been described are only particular illustrations, in no way limiting of the invention.
