Description

La présente invention concerne un système de fixation pour fausse-paroi à toile tendue, et notamment un faux-plafond à toile tendue, ainsi qu'une fausse-paroi comprenant une toile tendue reliée à au moins une lisse.The present invention relates to a fastening system for false wall fabric stretched, and in particular a false ceiling stretched canvas, and a false wall comprising a stretched fabric connected to at least one smooth.

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, par exemple en polychlorure de vinyle (PVC), 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 bel aspect.False walls, including false ceilings, conventionally comprise one or more stringers which are fixed to each of the walls and / or ceilings of a room, and a flexible sheet, for example polyvinyl chloride (PVC), and generally opaque, which is deformed by tension so that its edges, provided with attachment means, can be fixed to said smooth with the aid of these attachment means, taking care to stretch the fabric to provide a good beautiful appearance.

Toutefois, les fausses parois présentent très souvent l'inconvénient de laisser apparente au moins une partie de la lisse d'accrochage et/ou des moyens d'accrochage.However, the false walls very often have the disadvantage of leaving exposed at least a portion of the stringer and / or attachment means.

Pour remédier à cet inconvénient, on connaît des fausses parois, notamment les faux plafonds, comprenant une nappe souple dépourvue de moyens d'accrochage périphériques fixée sur une lisse d'accrochage et agencée de manière à masquer au moins en partie la lisse d'accrochage. Ce type de faux plafond de l'art antérieur est illustré sur les figures 1 et 2 du présent texte. Ainsi, faux plafond 101 comprend une lisse 102 fixée dans une partie supérieure d'un mur 103 par des moyens de fixation appropriés, tels que des vis (non représentées), et destinée à maintenir tendue une nappe souple 104 avantageusement en polychlorure de vinyle, dépourvue de moyens d'accrochage périphériques.To remedy this drawback, false walls are known, in particular false ceilings, comprising a flexible sheet devoid of peripheral fastening means attached to a stringer and arranged to hide at least part of the stringer . This type of false ceiling of the prior art is illustrated on the Figures 1 and 2 of this text. Thus, the false ceiling 101 comprises a rail 102 fixed in an upper part of a wall 103 by suitable fastening means, such as screws (not shown), and intended to keep a flexible sheet 104, advantageously made of polyvinyl chloride, taut. devoid of peripheral attachment means.

A cet égard, la lisse 102 comprend une aile d'appui 105 verticale s'étendant parallèlement et contre le mur 103, et une aile flexible 106 en forme générale de C inversé. L'aile d'appui 105 et l'aile flexible 106 sont reliées entre elles par une âme 107 issue à peu près à mi-hauteur de l'aile d'appui 105 et étant légèrement inclinée vers le bas pour rejoindre l'extrémité haute de l'aile flexible 106. De même, l'aile d'appui 105 et l'âme 107 sont reliées entre elles par une aile de jonction 108 rigide située au-dessus de ladite âme 107 permettant de renforcer la lisse 102.In this regard, the beam 102 comprises a vertical support wing 105 extending parallel and against the wall 103, and a flexible wing 106 in the general shape of C reversed. The support wing 105 and the flexible wing 106 are interconnected by a core 107 issued approximately halfway up the support wing 105 and being slightly inclined downwards to reach the high end. of the flexible wing 106. Similarly, the support wing 105 and the core 107 are interconnected by a rigid junction wing 108 located above said core 107 to reinforce the beam 102.

L'aile d'appui 105 comporte à son extrémité basse un organe de fermeture 109 s'étendant sensiblement perpendiculairement en direction de l'aile flexible 106.The support wing 105 has at its lower end a closure member 109 extending substantially perpendicular to the flexible wing 106.

En outre, l'aile flexible 106 comporte à son extrémité basse une portion mobile 110 comportant à son extrémité libre une mâchoire 111 prévue pour coopérer avec l'organe de fermeture 109 de l'aile d'appui 105, de manière à former conjointement une pince de prise de la nappe souple 104.In addition, the flexible wing 106 has at its lower end a movable portion 110 having at its free end a jaw 111 designed to cooperate with the closure member 109 of the support wing 105, so as to jointly form a gripping pliers of the flexible ply 104.

Enfin, la lisse 102 comprend à son extrémité basse du côté opposé de l'organe de fermeture 109, une lèvre souple 112 en forme générale de virgule palliant les défauts de planéité du mur 103 et assurant l'étanchéité entre le faux plafond 101 et le mur 103. On comprend bien, qu'une fois la lisse 102 fixée sur le mur 103, ladite lèvre souple 112 se trouve en général écrasée entre la lisse 102 fixée sur le mur 103.Finally, the arm 102 comprises at its bottom end on the opposite side of the closure member 109, a flexible lip 112 in the general form of a comma compensating for flatness defects of the wall 103 and ensuring the seal between the false ceiling 101 and the wall 103. It is understood that once the smooth 102 fixed on the wall 103, said flexible lip 112 is generally crushed between the smooth 102 fixed on the wall 103.

Ainsi avec une telle configuration pour fixer la nappe souple conformément à la figure 2, on procède de la manière suivante :

  • après avoir fixé la lisse 102 dans une partie supérieure d'un mur 103, on replie sur elle-même l'extrémité de la nappe souple 104 de manière à former un U,
  • on insère un outil de pose de type spatule entre les ailes de l'extrémité en forme de U, puis on pousse sur ladite extrémité, en maintenant l'aile libre du U, pour écarter la mâchoire 111 de l'aile flexible 106 et l'organe de fermeture 109 de l'aile d'appui 105, de façon à introduire l'extrémité de la nappe souple 104 entre la mâchoire 111 et l'organe de fermeture 109,
  • on obtient ensuite la tension de la nappe souple 104 souhaitée en tirant notamment sur l'aile libre de l'extrémité du U de la nappe souple 104,
  • ensuite, on retire l'outil de pose en laissant la nappe souple 104 maintenue pincée entre la mâchoire 111 et l'organe de fermeture 109,
  • enfin, on découpe autant que possible la partie de la nappe souple 104 dépassant de la pince.
Thus with such a configuration to fix the flexible sheet in accordance with the figure 2 we proceed as follows:
  • after having fixed the beam 102 in an upper part of a wall 103, the end of the flexible sheet 104 is folded on itself so as to form a U,
  • inserting a spatula-type installation tool between the wings of the U-shaped end, then pushing on said end, maintaining the free flange of the U, to separate the jaw 111 from the flexible wing 106 and the closure member 109 of the support wing 105, so as to introduce the end of the flexible sheet. 104 between the jaw 111 and the closure member 109,
  • the tension of the desired flexible ply 104 is then obtained by pulling in particular on the free flange of the end of the U of the flexible ply 104,
  • then, the laying tool is removed by leaving the flexible ply 104 pinched between the jaw 111 and the closure member 109,
  • finally, the portion of the flexible ply 104 protruding from the pliers is cut as much as possible.

On comprend bien que l'on peut avoir besoin de démonter la nappe souple 104 de manière à accéder, par exemple, à l'espace résiduel compris entre la nappe souple 104 et le plafond. A cet égard, pour pouvoir démonter facilement la nappe souple 104, il est nécessaire de laisser l'extrémité libre de la nappe souple 104 dépasser suffisamment de la pince formée de la mâchoire 111 et l'organe de fermeture 109. L'inconvénient de cette technique type est que la partie de la nappe souple 104 qui dépasse est particulièrement inesthétique.It is well understood that it may be necessary to remove the flexible sheet 104 so as to access, for example, the residual space between the flexible sheet 104 and the ceiling. In this respect, in order to be able to easily dismount the flexible sheet 104, it is necessary to allow the free end of the flexible sheet 104 to protrude sufficiently far from the clamp formed by the jaw 111 and the closure member 109. The disadvantage of this A typical technique is that the portion of the flexible web 104 that protrudes is particularly unsightly.

On peut alors couper la nappe souple 104 au ras de la pince avec un outil coupant approprié. Toutefois, cette configuration a pour inconvénient de rendre encore plus visible l'organe de fermeture 109 de l'aile d'appui 105 et par conséquent de créer des défauts d'aspect en raison de la différence d'aspect inévitable entre la matière de la lisse 102 et celle de la nappe souple 104.It is then possible to cut the flexible ply 104 flush with the pliers with a suitable cutting tool. However, this configuration has the disadvantage of making even more visible the closure member 109 of the support wing 105 and therefore to create appearance defects due to the inevitable difference in appearance between the material of the smooth 102 and that of the flexible web 104.

Enfin, ce faux-plafond 101 de l'art antérieur a pour dernier inconvénient de ne pas permettre un guidage de l'outil de pose, lors de la mise en place de la nappe souple 104 sur la lisse 102. En effet, lorsqu'on insère l'outil de pose entre les ailes de l'extrémité en forme de U de la nappe souple 104 pour introduire ladite extrémité entre la mâchoire 111 et l'organe de fermeture 109, on comprend bien que l'on a aucune visibilité sur la lisse 102. Par conséquent sans guidage, la mise en place de la nappe souple 104 est peu évidente.Finally, this false ceiling 101 of the prior art has the final disadvantage of not allowing a guide of the laying tool, during the establishment of the flexible sheet 104 on the smooth 102. Indeed, when we insert the laying tool between the wings of the U-shaped end of the flexible sheet 104 to introduce said end between the jaw 111 and the closure member 109, it is understood that there is no visibility on the smooth 102. Therefore without guidance, the establishment of the flexible web 104 is not obvious.

Le but de la présente invention est donc de pallier les inconvénients précédemment cités et de proposer une lisse pour fausse paroi tendue, par exemple un faux-plafond entre deux murs, constituée d'une nappe souple fixée par ses bords sur ladite lisse, permettant un montage et ultérieurement un démontage facile de ladite nappe souple 104. En outre, cette lisse, qui est simple et économique, n'est pas visible, après montage de ladite fausse paroi.The purpose of the present invention is therefore to overcome the aforementioned drawbacks and to provide a smooth wall for false wall, for example a false ceiling between two walls, consisting of a flexible sheet secured by its edges on said rail, allowing a mounting and subsequently easy disassembly of said flexible web 104. In addition, this smooth, which is simple and economical, is not visible after mounting said false wall.

FR 2 699 212 decrit un systeme de fixation selon le préambule de la revendication 1. FR 2,699,212 describes a fastening system according to the preamble of claim 1.

Conformément à l'invention, il est donc proposé une lisse pour fausse paroi tendue, notamment un faux-plafond, constituée d'une nappe souple apte à être fixée par ses bordures, ladite lisse étant formée de profils aboutés et fixée au mur et/ou au plafond d'un local, et comprenant une aile externe d'appui s'étendant parallèlement au mur ou au plafond , une aile interne flexible et une âme issue à mi-hauteur de l'aile externe et reliant cette dernière à une des extrémités de l'aile interne, ladite aile externe comportant un organe de fermeture s'étendant en direction de l'aile interne qui comporte à son autre extrémité une portion mobile pourvue à son extrémité libre d'une mâchoire prévue pour coopérer avec l'organe de fermeture de l'aile externe, de manière à former conjointement une pince de prise de la nappe souple. Ladite lisse est remarquable en ce qu'elle est apte à être fixée sur le mur ou au plafond dudit local avec un jeu de manière à avoir un espace résiduel entre l'aile externe et ledit mur ou ledit plafond et en ce que l'organe de fermeture de l'aile externe et la portion mobile de l'aile interne forment conjointement une rainure assurant le guidage de l'outil de pose pour le du montage de la nappe souple sur la lisse vers la jonction entre ledit organe de fermeture et une machoire.According to the invention, it is therefore proposed a smooth for false wall tension, including a false ceiling, consisting of a flexible sheet capable of being fixed by its borders, said smooth being formed of abutting profiles and fixed to the wall and / or on the ceiling of a room, and comprising an outer bearing flange extending parallel to the wall or ceiling, a flexible inner wing and a core coming halfway up the outer wing and connecting the latter to one of the ends of the inner wing, said outer wing having a closure member extending towards the inner wing which has at its other end a movable portion provided at its free end with a jaw adapted to cooperate with the organ closing the outer flange, so as to jointly form a gripper gripping the flexible web. Said smooth is remarkable in that it is adapted to be fixed on the wall or ceiling of said room with a game so as to have a residual space between the outer wing and said wall or said ceiling and in that the closure member of the outer flange and the movable portion of the inner flange together form a groove for guiding the laying tool for the mounting of the flexible ply on the smooth towards the junction between said closure member and a jaw.

Selon un mode de réalisation préférée, la rainure formée par l'organe de fermeture et la portion mobile a une section en forme de V inversé.According to a preferred embodiment, the groove formed by the closure member and the movable portion has an inverted V-shaped section.

Selon un mode de réalisation préférée, le jeu entre l'aile d'appui et le mur ou plafond est très faible, de l'ordre de 2 mm, ce jeu étant suffisant pour masquer le surplus de la nappe souple après le montage de la fausse paroi, tout en restant quasiment invisible à l'oeil.According to a preferred embodiment, the clearance between the support flange and the wall or ceiling is very small, of the order of 2 mm, this clearance being sufficient to mask the surplus of the flexible ply after the assembly of the false wall, while remaining almost invisible to the eye.

D'autres avantages et caractéristiques ressortiront mieux de la description qui va suivre d'une variante d'exécution d'une lisse selon l'invention en référence aux figures annexées sur lesquelles :

  • la figure 1 est une vue en coupe verticale d'une lisse fixée à la partie supérieure d'un mur d'une pièce selon l'art antérieur ;
  • la figure 2 est une vue en coupe verticale partielle d'un faux plafond constitué par une nappe tendue, et comportant la lisse, telle que celle représentée sur la figure 1, fixée à la partie supérieure d'un mur d'une pièce selon l'art antérieur ;
  • la figure 3 est une section à grande échelle d'une lisse fixée à la partie supérieure d'un mur d'une pièce, conforme à l'invention ;
  • la figure 4 est une vue en coupe verticale partielle, à la même échelle et selon le même angle de vue que la figure 2, d'un faux plafond constitué d'une nappe souple accrochée tendue sur une lisse conforme à l'invention.
Other advantages and features will become more apparent from the following description of an alternative embodiment of a rail according to the invention with reference to the appended figures in which:
  • the figure 1 is a vertical sectional view of a rail attached to the upper part of a wall of a room according to the prior art;
  • the figure 2 is a partial vertical sectional view of a false ceiling constituted by a stretched sheet, and comprising the stringer, such as that shown in FIG. figure 1 fixed to the upper part of a wall of a room according to the prior art;
  • the figure 3 is a large-scale section of a rail attached to the upper part of a wall of a room, according to the invention;
  • the figure 4 is a partial vertical sectional view, at the same scale and at the same angle of view as the figure 2 , a false ceiling consisting of a flexible sheet hung stretched on a rail according to the invention.

On décrira dans cette variante d'exécution en aucun cas non limitative de l'invention, une lisse pour faux-plafond tendu, toutefois, la lisse, selon l'invention, peut évidemment être employée pour une fausse paroi de type faux-mur ou similaire.We will describe in this variant of execution in no non-limiting case of the invention, a smooth suspended false ceiling, however, the smooth, according to the invention, can obviously be used for a fake false-wall type wall or the like.

Ainsi, la figure 4 représente la partie extrême d'un faux plafond 1 suivant l'invention, constitué par une nappe souple 2 tendue horizontalement en dessous du plafond 3 d'un local. Cette nappe souple 2 est fixée le long de ses bords à une lisse 4, représentée sur la figure 4, ladite lisse 4 étant formée de profils aboutés et fixée au mur 5 dudit local, par des moyens de fixation appropriés, tels que des vis (non représentées).So, the figure 4 represents the end portion of a false ceiling 1 according to the invention, constituted by a flexible sheet 2 stretched horizontally below the ceiling 3 of a room. This flexible sheet 2 is fixed along its edges to a smooth 4, shown on the figure 4 said lug 4 being formed of abutting profiles and fixed to the wall 5 of said room, by suitable fixing means, such as screws (not shown).

A cet égard, la lisse 4 comprend une aile externe 6 verticale d'appui s'étendant parallèlement au mur 5 lorsque ladite lisse 4 est fixée au mur 5 dudit local, une aile interne 7 flexible de préférence en forme générale de J et une âme 8 issue à mi-hauteur de l'aile externe 6 et reliant cette dernière à l'extrémité haute de l'aile interne 7.In this respect, the arm 4 comprises an external vertical support flange 6 extending parallel to the wall 5 when said arm 4 is fixed to the wall 5 of said room, an inner wing 7 preferably flexible in the general shape of J and a soul 8 issuing at mid-height of the outer wing 6 and connecting the latter to the upper end of the inner wing 7.

De même, l'aile externe 6 et l'âme 8 sont reliées entre elles par une aile de jonction 9 souple située en dessous de ladite âme 8 faisant office de ressort et permettant une flexibilité plus importante de la lisse 4.Similarly, the outer flange 6 and the core 8 are interconnected by a flexible junction flange 9 located below said core 8 acting as a spring and allowing greater flexibility of the flange 4.

Par ailleurs, l'aile externe 6 comporte à son extrémité basse un organe de fermeture 10 s'étendant en direction de l'aile interne 7.Furthermore, the outer wing 6 has at its lower end a closure member 10 extending towards the inner wing 7.

En outre, l'aile interne 7 comporte à son extrémité libre basse une portion mobile 11 pourvue à son extrémité libre d'une mâchoire 12 prévue pour coopérer avec l'organe de fermeture 10 de l'aile externe 6, de manière à former conjointement une pince de prise de la nappe souple 2.In addition, the inner wing 7 has at its free end a low mobile portion 11 provided at its free end with a jaw 12 provided to cooperate with the closure member 10 of the outer flange 6, so as to form jointly a gripper of the flexible sheet 2.

L'organe de fermeture 10 de l'aile externe 6 et la portion mobile 11 de l'aile interne 7 forment une rainure permettant le guidage de l'outil de pose lors du montage de la nappe souple 2 sur la lisse 4. En effet, on comprend bien que le fait d'avoir une rainure de dimensions suffisantes sur la lisse 4 facilite l'introduction de la nappe souple 2 entre l'organe de fermeture 10 de l'aile externe 6 et la portion mobile 11 de l'aile interne 7. Avec une telle configuration, l'outil de pose est guidé normalement et automatiquement, au moment de l'enclenchement de la nappe souple 2 vers la jonction entre ledit organe de fermeture 10 et la mâchoire 12.The closure member 10 of the outer flange 6 and the movable portion 11 of the inner flange 7 form a groove for guiding the laying tool during assembly of the flexible sheet 2 on the rail 4. Indeed, it is clear that having a groove of sufficient size on the rail 4 facilitates the introduction of the flexible web 2 between the closure member 10 of the wing 6 and the movable portion 11 of the inner wing 7. With such a configuration, the laying tool is guided normally and automatically, at the time of engagement of the flexible sheet 2 to the junction between said closure member 10 and the jaw 12.

Dans un mode de réalisation préférentiel, ladite rainure a une section en forme générale de V inversé évasé dont le sommet est la jonction entre ledit organe de fermeture 10 et la mâchoire 12.In a preferred embodiment, said groove has a generally inverted flared V-shaped section whose apex is the junction between said closure member 10 and the jaw 12.

L'aile externe 6 comporte également à son extrémité basse du côté opposé de l'organe de fermeture 10, une lèvre 13 en forme générale de virgule palliant les défauts de planéité du mur 5 et assurant l'étanchéité entre le faux plafond 1 et le mur 5.The outer flange 6 also has at its lower end on the opposite side of the closure member 10, a lip 13 in the general form of a comma palliate the unevenness of the wall 5 and ensuring the tightness between the false ceiling 1 and the wall 5.

Par ailleurs, la lisse 4 est fixée sur le mur 5 avec un jeu. A cet égard, l'aile externe 6 comporte une pluralité de talons 14 issus perpendiculairement de sa face verticale située du côté du mur 5. Ainsi, lorsque l'on fixe la lisse 4 sur le mur 5, elle est en appui sur les talons 14 et de fait on a un jeu et un espace résiduel 15 entre l'aile externe 6 et ledit mur 5.Furthermore, the arm 4 is fixed on the wall 5 with a clearance. In this respect, the outer wing 6 has a plurality of heels 14 perpendicularly from its vertical face located on the side of the wall 5. Thus, when one fixed the smooth 4 on the wall 5, it is supported on the heels 14 and in fact there is a clearance and a residual space 15 between the outer flange 6 and said wall 5.

Comme précédemment décrit, pour monter la nappe souple 2, on replie sur elle-même l'extrémité de ladite nappe souple 2 de manière à former un U, puis on introduit ladite extrémité entre la mâchoire 12 de l'aile interne 7 et l'organe de fermeture 10 de l'aile externe 6 grâce à un outil de pose du type spatule forçant l'introduction entre les ailes du U. On obtient ensuite la tension de la nappe souple 2 souhaitée en tirant notamment sur la partie libre de l'extrémité du U de la nappe souple 2. Ce procédé de montage nécessite par conséquent d'avoir un surplus inesthétique de nappe souple 2 après le montage de cette dernière.As previously described, in order to assemble the flexible sheet 2, the end of said flexible sheet 2 is folded on itself so as to form a U, and then said end is introduced between the jaw 12 of the inner wing 7 and the closing member 10 of the outer flange 6 by means of a spatula-type laying tool forcing insertion between the wings of the U. The tension of the desired flexible ply 2 is then obtained by pulling in particular on the free part of the end of the U of the flexible ply 2. This method of assembly therefore requires an unsightly surplus of flexible ply 2 after mounting the latter.

Pour pallier cet inconvénient et obtenir un aspect parfait du faux-plafond 1 maintenu sur la lisse 4, ledit surplus de nappe souple 2, après insertion dans la lisse 4, peut être dissimulé dans l'espace résiduel 15 entre l'aile externe 6 et ledit mur 5 en recouvrant ainsi la totalité de la lisse 4 qui n'est alors plus visible depuis le local.To overcome this drawback and obtain a perfect appearance of the suspended ceiling 1 maintained on the rail 4, said surplus flexible web 2, after insertion into the rail 4, can be concealed in the residual space 15 between the outer wing 6 and said wall 5 thus covering the entire smooth 4 which is then no longer visible from the local.

On comprend bien que ledit espace résiduel 15 permet une insertion aisée du surplus de nappe souple 2 sans effort excessif pour l'opérateur effectuant la manipulation et sans risque de dégradation de l'aile externe 6, du mur 5 et de la nappe souple 2.It is well understood that said residual space 15 allows easy insertion of the surplus flexible sheet 2 without excessive effort for the operator performing the manipulation and without risk of degradation of the outer flange 6, the wall 5 and the flexible sheet 2.

De plus, conformément à la figure 4, la lèvre souple 13 de l'aile externe 6 maintient le surplus de nappe souple 2 en appui contre le mur 5 du local et évite ainsi au surplus de ressortir dudit espace résiduel 15.In addition, in accordance with figure 4 , the flexible lip 13 of the outer flange 6 maintains the surplus of flexible ply 2 in abutment against the wall 5 of the room and thus avoids the surplus to emerge from said residual space 15.

Par ailleurs, le jeu entre l'aile externe 6 et le mur 5 étant très faible, de l'ordre de 2 mm, il est suffisant pour cacher le surplus de la nappe souple 2 après montage du faux-plafond 1 et demeurer quasiment invisible à l'oeil.Furthermore, the clearance between the outer flange 6 and the wall 5 is very small, of the order of 2 mm, it is sufficient to hide the surplus of the flexible ply 2 after mounting the false ceiling 1 and remain almost invisible at the eye.

On comprend bien qu'avec une telle configuration, le faux-plafond présente un aspect uniforme sur toute sa surface, ce qui renforce l'esthétique d'ensemble dudit faux-plafond 1.It is understood that with such a configuration, the false ceiling has a uniform appearance over its entire surface, which enhances the overall aesthetics of said false ceiling 1.

La lisse 4, selon l'invention, est avantageusement réalisée en matière plastique extrudée, par exemple, en polychlorure de vinyle (PVC). Par ailleurs, pour améliorer sa flexibilité partielle, la lisse 4, qui est globalement rigide, comporte également des zones souples, telles que l'aile de jonction 9, la portion mobile 11 et la lèvre 13.Smooth 4, according to the invention, is advantageously made of extruded plastic, for example, polyvinyl chloride (PVC). On the other hand, to improve its partial flexibility, the arm 4, which is generally rigid, also comprises flexible zones, such as the connecting wing 9, the movable portion 11 and the lip 13.

Enfin, il va de soi que l'exemple de lisse 4 pour faux-plafond conforme à l'invention qui vient d'être décrit n'est qu'une illustration particulière, en aucun cas limitative de l'invention ; elle est notamment applicable pour des faux-murs ou encore pour des caissons lumineux ou non, pourvus d'une fausse paroi recouvrant au moins leur face inférieure horizontale.Finally, it goes without saying that the example of smooth 4 for False ceiling according to the invention which has just been described is only a particular illustration, in no way limiting of the invention; it is particularly applicable for false walls or for light boxes or not, provided with a false wall covering at least their lower horizontal face.
