Description

Système de fixation pour la réalisation  Fixing system for the realization
de revêtements tendus  of stretched coverings
Domaine de 1 ' invention Field of the invention
La présente invention concerne le domaine des revêtements muraux ou de plafond à toile tendue. The present invention relates to the field of wall coverings or ceiling stretched canvas.
De tels dispositifs de revêtements comprennent un panneau classiquement formé d'une nappe tendue fixée à la base d'un châssis, généralement — mais pas nécessairement parallélépipédique , qui est constitué de l'association d'éléments profilés qui forment chacun de ses côtés. A cette fin, la nappe comporte un moyen d'accrochage fixé à la périphérie de ladite toile. Par exemple, comme cela est décrit dans le brevet FR 2630476, la nappe peut être munie d'une bordure périphérique en forme de harpon. Un autre moyen d'accrochage consiste en des clips. La nappe tendue est de préférence en un matériau polymère synthétique, par exemple du polychlorure de vinyle.  Such coating devices comprise a panel conventionally formed of a stretched sheet attached to the base of a frame, generally - but not necessarily parallelepiped, which consists of the combination of profiled elements which form each of its sides. To this end, the sheet comprises a fastening means attached to the periphery of said fabric. For example, as described in patent FR 2630476, the web may be provided with a peripheral edge in the form of a harpoon. Another means of attachment consists of clips. The stretched web is preferably of a synthetic polymeric material, for example polyvinyl chloride.
Dans certaines réalisations, deux toiles sont prévues pour réaliser un volume fermé dans lequel est placé un éclairage. La toile supérieure empêche le dépôt de salissures sur la toile inférieure de type translucide, éclairée par 1 ' arrière .  In some embodiments, two canvases are provided to achieve a closed volume in which is placed a lighting. The upper fabric prevents the deposit of dirt on the lower fabric translucent type, illuminated by one back.
Eventuellement, une troisième nappe tendue s'étend parallèlement aux deux autres, dans le but de créer des parois présentant des performances d'absorption acoustiques accrues ou encore des ensembles lumineux générant un effet esthétique nouveau .  Optionally, a third stretched sheet extends parallel to the other two, in order to create walls having increased acoustic absorption performance or light sets generating a new aesthetic effect.
Etat de la technique State of the art
On connaît dans l'état de la technique de nombreuses solutions de système pour la réalisation de revêtements en toile tendue, beaucoup de ces brevets émanant de la demanderesse . Numerous system solutions are known in the state of the art for the production of coatings in stretched canvas, many of these patents emanating from the plaintiff.
On connaît par exemple le brevet français FR2475093 décrivant un profilé constituant une lisse extérieure d'un faux plafond ou un faux mur constitué par une cornière dont une aile verticale est appliquée contre un mur. Une aile horizontale présente un épaulement s ' étendant en direction de l'aile verticale pour assurer l'accrochage d'une bordure en forme de crochet solidaire d'une feuille de matière plastique ou toile maintenue tendue par le profilé. Ce profilé présente un épaulement horizontal définit, avec l'aile horizontale, une gorge à section droite en U ouverte vers l'aile verticale. Un pan coupé prévu dans 1 ' angle de la cornière constituant le profilé se raccorde à l'aile horizontale de manière à définir, entre ce pan coupe et 1 ' épaulement , un passage étroit de largeur légèrement supérieure à l'épaisseur de la partie de la bordure qui est engagée dans la gorge en U.  For example, the French patent FR2475093 describes a profile constituting an outer smooth of a false ceiling or a false wall constituted by an angle with a vertical wing is applied against a wall. A horizontal flange has a shoulder extending in the direction of the vertical flange to ensure the attachment of a hook-shaped edge secured to a sheet of plastic or web held taut by the profile. This profile has a horizontal shoulder defines, with the horizontal flange, a straight U-section groove open towards the vertical flange. A cutaway provided in the angle of the angle constituting the profile is connected to the horizontal flange so as to define, between the cutter and the shoulder, a narrow passage of width slightly greater than the thickness of the portion of the border that is engaged in the U-shaped groove.
Le brevet français FR2597906 décrit un autre exemple de profilé de bordure destiné à être fixé à la périphérie d'un matériau souple formant un faux plafond. Vu en coupe transversale, ce profilé présente une première aile horizontale, une seconde aile qui s'étend vers le bas à partir de la première aile, et au moins une première partie en forme de crochet, dans laquelle peut être engagé le profilé de bordure, lui-même en forme de crochet. La première partie en forme de crochet est située à la partie inférieure de la seconde aile, du coté orienté vers le mur, et se raccorde à la partie inférieure par une surface dépourvue d'arête vive saillante. Le profilé de bordure a, vu en coupe transversale, sensiblement la forme d'une ancre.  French patent FR2597906 describes another example of an edge profile intended to be fastened to the periphery of a flexible material forming a false ceiling. Seen in cross section, this profile has a first horizontal wing, a second wing that extends downwardly from the first wing, and at least a first hook-shaped portion, in which can be engaged the edge profile. , itself in the form of a hook. The first hook-shaped portion is located at the lower part of the second wing, on the side facing the wall, and is connected to the lower part by a surface free of sharp edge protruding. The edge profile has, in cross section, substantially the shape of an anchor.
La demande internationale WO2004106663 propose une autre solution de modules destinés au recouvrement, par exemple, de parois, de plafonds et d'autres éléments de limite tels que parois mobiles. Les modules sont destinés à être adaptés non seulement à des surfaces planes mais aussi à des surfaces incurvées; ils peuvent être dotés de propriétés d'absorption et/ou de réflexion de bruit de manière à influencer l'acoustique, par exemple, d'une pièce. Dans une forme de base, les modules comprennent une face avant, qui peut être plane, incurvée ou munie de diverses structures de surface, la face avant étant liée au moyen d'au moins deux parties de bord disposées latéralement et destinées à être raccordées aux points de fixation, de manière à être reliées amovibles à des rails ou, par exemple, à une paroi. Dans certains modes de réalisation, les modules sont des corps creux, et la cavité formée à l'intérieur d'un module peut s'utiliser à des fins d'atténuation acoustique, la cavité étant reliée avec l'environnement par des ouvertures dans le module. L'invention concerne aussi des systèmes de modules, lesdits systèmes comprenant d'une manière générale une pluralité de plans situés à des distances différentes par rapport à la paroi. Des passages sont ménagés entre les modules adjacents d'un plan donné de manière à permettre 1 ' accès à la zone derrière ces modules et à des modules supplémentaires placés dans cette région. Ces systèmes composites peuvent s'utiliser d'une façon avantageuse pour améliorer l'acoustique d'une pièce; en outre, ces passages peuvent s'utiliser à des fins de climatisation/chauffage ainsi que dans de nombreuses autres applications mentionnées dans la description. International application WO2004106663 proposes another solution modules for covering, for example, walls, ceilings and other boundary elements such as moving walls. The modules are intended to be adapted not only to flat surfaces but also to surfaces curved; they can be endowed with absorption and / or noise reflection properties so as to influence the acoustics, for example, of a room. In a basic form, the modules comprise a front face, which may be flat, curved or provided with various surface structures, the front face being connected by means of at least two edge portions arranged laterally and intended to be connected to the fixing points, so as to be releasably connected to rails or, for example, to a wall.

Dans l'état de la technique, on connaît aussi des solutions prévoyant la mise sous tension de la toile par l'ensachage d'un cadre, avec une toile formant un sachet.  In the state of the art, solutions are also known which provide for the tensioning of the fabric by bagging a frame, with a fabric forming a bag.
La demande de brevet EP1783292 décrit par exemple un cadre de dalle de faux plafond, au moins un côté de ce cadre comprenant, lorsque vu en coupe, une paroi supérieure et une paroi latérale, caractérisé en ce que la paroi latérale comprend une partie supérieure sensiblement verticale et une partie inférieure, les parties inférieure et supérieure définissant un angle obtus, en face externe du cadre de dalle. Cette solution n'est en réalité pas très satisfaisante : elle ne permet de tendre correctement la toile que sur des cadres rectangulaires de petite dimension, et n'est pas appropriée à des configurations plus complexes. Par ailleurs, elle implique que la toile entoure toutes les faces extérieures du cadre, ce qui peut occasionner des dégradations par frottement du cadre sur un support. The patent application EP1783292 describes for example a false ceiling slab frame, at least one side of this frame comprising, when viewed in section, an upper wall and a side wall, characterized in that the side wall comprises an upper portion substantially vertical and a lower part, the lower and upper parts defining an obtuse angle, on the outer face of the slab frame. This solution is actually not very satisfactory: it only allows the fabric to be stretched correctly on rectangular frames of small size, and is not suitable for more complex configurations. Furthermore, it implies that the fabric surrounds all the outer faces of the frame, which can cause damage by friction of the frame on a support.
On connaît aussi des solutions prévoyant un rétroéclairage. A titre d'exemple, la demande de brevet EP2610550 décrit un dispositif d'éclairage à tubes néon ou à LED comprenant une platine avec un fond sensiblement plan et au moins un tube néon ou une source lumineuse de type LED fixé à ladite platine et s ' étendant parallèlement audit fond remarquable en ce qu'il est muni d'un écran diffuseur relié à ladite platine par des moyens de liaison et comportant une toile souple tendue qui s'étend au moins au droit de ladite platine, parallèlement au fond de celle-ci.  There are also known solutions providing a backlight. By way of example, the patent application EP2610550 describes a neon tube or LED lighting device comprising a plate with a substantially plane bottom and at least one neon tube or an LED type light source fixed to said plate and extending parallel to said remarkable bottom in that it is provided with a diffuser screen connected to said plate by connecting means and comprising a stretched flexible fabric which extends at least in line with said plate, parallel to the bottom of the -this.

Le brevet EP2607564 décrit un dalle pour faux plafond, comprenant un cadre réalisé à partir de profilés aboutés et une nappe fixée tendue sur ledit cadre, chaque profilé comportant une paroi supérieure, une paroi latérale issue de 1 ' une des extrémités de ladite paroi supérieure et une paroi de renfort réunissant les extrémités libres des parois supérieure et latérale de manière à ce que chaque profilé ait une section transversale en forme générale de triangle. La dalle comporte un clip de fixation et la paroi supérieure est pourvue d'au moins un logement apte à coopérer de façon amovible avec ledit clip de fixation pour fixer la nappe tendue sur ledit cadre en la maintenant serrée dans ledit logement par le clip de fixation. EP2607564 discloses a slab for false ceiling, comprising a frame made from abutting profiles and a fixed sheet stretched on said frame, each section having an upper wall, a side wall coming from one of the ends of said upper wall and a reinforcing wall joining the free ends of the upper and lateral walls so that each section has a generally triangular cross section. The slab comprises a fastening clip and the upper wall is provided with at least one housing adapted to cooperate detachably with said fastening clip for fixing the sheet stretched on said frame by keeping it clamped in said housing by the fastening clip.
La demanderesse est également titulaire de la demande internationale WO2012089937. Elle concerne un dispositif de fausse paroi comportant un panneau formé d'au moins une nappe tendue fixée à la base d'un châssis, constitué par l'assemblage d'éléments profilés formant ses cotés, remarquable en ce que chaque élément profilé du châssis présente une section droite avec une première face supérieure, une base opposée à ladite première face supérieure, une seconde face externe et une troisième face interne, en regard de la seconde face externe, chaque profilé comportant au moins trois logements destinés chacun à recevoir une bordure périphérique d'une nappe tendue, un premier logement situé à proximité de la première face supérieure du profilé, un second logement situé à proximité de la base dudit profilé et au moins un troisième logement, aménagé dans la face interne du profilé .  The applicant also holds the international application WO2012089937.

Inconvénients de l'art antérieur Les solutions de l'art antérieur ne sont pas totalement satisfaisantes car la toile tendue est mal protégée à certains endroits où elle est en contact avec le profilé formant le cadre. Par ailleurs, pour les cadres de grandes dimensions, la rigidité est insuffisante sauf à prévoir des profilés massifs, et donc lourds . Disadvantages of the Prior Art The solutions of the prior art are not entirely satisfactory because the stretched fabric is poorly protected in some places where it is in contact with the profile forming the frame.

The vertical portion (150) is extended by a longitudinal band (152) extending perpendicular to this vertical portion (150), and therefore parallel to the median plane
(142) . Cette bande longitudinale (152) permet la fixation d'un éventuel isolant acoustique. Cette bande longitudinale (152) se termine par un rebord longitudinal (151) venant s'appuyer contre la surface de la paroi verticale de la cornière. (142). This longitudinal strip (152) allows the attachment of a possible acoustic insulation. This longitudinal band (152) ends with a longitudinal flange (151) coming to bear against the surface of the vertical wall of the angle.
Le bord de ce rebord longitudinal (151) vient à l'aplomb du fond (153) de la partie inférieure (140) en forme de « C ».  The edge of this longitudinal rim (151) is in line with the bottom (153) of the bottom portion (140) shaped "C".
La figure 8 représente une variante de réalisation où la partie verticale (150) est avancée pour permettre la réalisation d'une bande longitudinale (152) plus profonde.  Figure 8 shows an alternative embodiment where the vertical portion (150) is advanced to allow the realization of a longitudinal strip (152) deeper.
La figure 9 représente une variante de réalisation où le profilé présente une cavité longitudinale (154).  FIG. 9 represents a variant embodiment in which the profile has a longitudinal cavity (154).
Les figures 10 à 12 représentent un autre exemple de respectivement de cornière, de lisse et de l'assemblage de la lisse dans la cornière. La cornière présente une section représentée en figure 10, avec une paroi verticale (200) présentant une hauteur de 24 millimètres dans l'exemple décrit, et une paroi inférieure (201) présentant une largeur de 23 millimètres et s 'étendant perpendiculairement à la paroi verticale (200). Cette paroi inférieure (201) est prolongée, du coté opposé à la paroi verticale (200), par un rebord (202) d'une hauteur de 8 millimètres, prolongé lui-même par une lèvre (203) parallèle à la paroi inférieure (201). La lèvre (203) présente à sa surface inférieure un chanfrein (205). Cette lèvre (203) définit avec la paroi inférieure (201) et le rebord (202) une gorge (204) destinée à recevoir la partie inférieure de la lisse . Figures 10 to 12 show another example respectively of angle, smooth and assembly of the bar in the angle. The bracket has a section shown in Figure 10, with a vertical wall (200) having a height of 24 millimeters in the example described, and a bottom wall (201) having a width of 23 millimeters and extending perpendicular to the wall vertical (200). This lower wall (201) is extended, on the opposite side to the vertical wall (200), by a rim (202) with a height of 8 millimeters, itself extended by a lip (203) parallel to the bottom wall ( 201). The lip (203) has on its lower surface a chamfer (205). This lip (203) defines with the bottom wall (201) and the rim (202) a groove (204) for receiving the lower part of the rail.
La paroi verticale (200) présente sur sa surface interne un ergot (210), situé dans l'exemple décrit à la moitié de la hauteur, et s 'étendant sur environ 1,5 millimètres.  The vertical wall (200) has on its inner surface a lug (210), located in the example described at half the height, and extending about 1.5 millimeters.
La lisse représentée en vue en coupe en figure 11 est extrudée en matière plastique. La face arrière (230) présente un logement (231) destiné à coopérer avec l'ergot (210) lorsque la lisse est engagée dans la cornière.  The arm shown in sectional view in Figure 11 is extruded plastic. The rear face (230) has a housing (231) intended to cooperate with the lug (210) when the arm is engaged in the angle.
La lisse présente des dents avant écartées (232, 233) et un groupe de deux dents bifurquées (234, 235) situés dans la partie arrière de la lame (236), s 'étendant perpendiculairement à la face arrière (230).  The rail has spaced front teeth (232, 233) and a group of two bifurcated teeth (234, 235) located in the rear portion of the blade (236) extending perpendicular to the rear face (230).
La face inférieure (237) présente à l'avant une cale The underside (237) has a wedge at the front
(238) de section complémentaire à la section de la gorge (204) de la cornière. (238) complementary section to the section of the groove (204) of the angle.
Une zone intermédiaire (239) présente une surface supérieure (240) formant une pente complémentaire au chanfrein (205), et une surface inférieure (241) parallèle.  An intermediate zone (239) has an upper surface (240) forming a slope complementary to the chamfer (205), and a lower surface (241) parallel.
En arrière de cette zone intermédiaire (239), la face inférieure (237) présente une protubérance (242) formant une surface supérieure (243) présentant deux nervures de forme complémentaire à l'extrémité des dents bifurquées (234, 235), pour assurer le pincement de la toile lorsque celle-ci est mis en place. Behind this intermediate zone (239), the lower face (237) has a protuberance (242) forming an upper surface (243) having two ribs of complementary shape at the end of the bifurcated teeth (234, 235), to ensure the pinching of the fabric when it is put in place.
La lisse présente dans sa partie intérieure arrière un canal (250) permettant l'engagement de l'ourlet de la toile.  The smooth has in its inner back a channel (250) for engaging the hem of the fabric.
La lisse est introduite dans la cornière par un basculement permettant l'introduction de la cale (238) de la face inférieure dans la gorge (204) de la cornière. Ensuite, la cornière est rabattue pour épouser la surface intérieure de la cornière. L'ergot (210) vient alors se loger dans le logement (231) pour renforcer le maintien de l'assemblage.  The bar is introduced into the angle by a tilting allowing the introduction of the wedge (238) of the lower face in the groove (204) of the angle. Then, the angle is folded to marry the inner surface of the angle. The lug (210) is then housed in the housing (231) to strengthen the maintenance of the assembly.
Les dents (232, 233) viennent alors en contact avec la surface supérieure de la lèvre (203) de la cornière, et assure le maintien par pincement de la toile (figure 12). La figure 13 représente une vue d'une variante de réalisation où la cornière (500) est fixée sur une paroi par des boulons (501). La cornière (500) présente une forme générale en « C », avec une paroi arrière (502) présentant des perçages pour le passage de boulons (501). Cette paroi arrière (502) est prolongée perpendiculairement par une paroi inférieure (503) se terminant par une bordure avant (504) présentant une lame (505) parallèle à la paroi inférieure (503) et définissant une rainure dans laquelle viendra se loger la partie avant de la lisse (600).  The teeth (232, 233) then come into contact with the upper surface of the lip (203) of the angle, and ensures the holding by pinching of the fabric (Figure 12). Figure 13 shows a view of an alternative embodiment wherein the bracket (500) is fixed on a wall by bolts (501). The bracket (500) has a general "C" shape, with a rear wall (502) having holes for the passage of bolts (501). This rear wall (502) is extended perpendicularly by a bottom wall (503) ending in a front edge (504) having a blade (505) parallel to the bottom wall (503) and defining a groove in which will be housed the part before the smooth (600).
La surface supérieure (506) de la lame (505) est crantée pour former une zone de retenue d'une toile ou d'un revêtement tendu .  The upper surface (506) of the blade (505) is serrated to form a retaining area of a stretched fabric or liner.
La paroi arrière (502) présente à sa surface intérieure une nervure (507) assurant la retenue du talon (603) de la lisse (600), qui peut ainsi s ' encliqueter dans la cornière (500). Ce talon (603) prolonge la semelle (601) de la lisse (600). Cette semelle (601) se termine à sa partie avant par une zone (602) complémentaire de la rainure prévue à l'avant de la cornière (500). La lisse (600) présente comme dans l'exemple précédent des dents bifurquées (234, 235) venant au contact de la surface crantée (506) pour assurer le maintien d'une toile introduite en force dans l'espace entre la cornière et la lisse. The rear wall (502) has on its inner surface a rib (507) ensuring the retention of the heel (603) of the arm (600), which can snap into the angle (500). This heel (603) extends the sole (601) of the bar (600). This sole (601) ends at its front part by a zone (602) complementary to the groove provided at the front of the angle (500). The arm (600) has, as in the previous example, bifurcated teeth (234, 235) coming into contact with the notched surface (506) to maintain a fabric forcefully introduced into the space between the angle and the smooth.
La figure 14 représente une variante de réalisation où la lisse présente deux talons (603, 604) parallèles définissant une rainure (605) dans laquelle vient se loger nervure (507).  FIG. 14 represents a variant embodiment in which the rail has two parallel heels (603, 604) defining a groove (605) in which the rib (507) is received.
