Description

Domaine techniqueTechnical area

L'invention se rattache au secteur de l'architecture d'intérieur. Elle concerne plus particulièrement une nouvelle structure de dalles de faux plafonds, destinées à équiper des locaux de tailles très diverses pouvant aller de quelques mètres à quelques centaines de mètres carrés. Elle vise plus précisément l'utilisation d'une feuille textile pour la réalisation de dalles de faux plafonds.The invention relates to the interior architecture sector. It relates to more particularly a new structure of false ceiling tiles, intended for equip premises of very different sizes ranging from a few meters to a few hundred square meters. It more specifically relates to the use of a textile sheet for making false ceiling tiles.

Techniques antérieuresPrevious techniques

Comme on le sait, les faux plafonds sont généralement réalisés à partir de dalles unitaires qui sont mises en place sur un châssis lui-même suspendu sous le plafond de la pièce ou du bâtiment dans lequel le faux plafond est installé.As we know, false ceilings are generally made from unitary slabs which are placed on a frame itself suspended under the ceiling of the room or building in which the false ceiling is installed.

Un tel châssis est généralement constitué d'un quadrillage réalisé à partir de profilés en T inversé, le châssis étant relié au plafond proprement dit par un ensemble de suspentes.Such a chassis generally consists of a grid made from inverted T profiles, the chassis being connected to the ceiling proper by a set of lines.

Le quadrillage défini par ces profilés est agencé pour recevoir des dalles dont la périphérie repose sur les zones horizontales des profilés en T précités.The grid defined by these profiles is arranged to receive slabs of which the periphery rests on the horizontal zones of the aforementioned T profiles.

Les dalles montées sur ces châssis sont généralement essentiellement rigides, et réalisées à partir de matériaux incorporant une fraction importante de plâtre. De telles dalles sont donc relativement lourdes et encombrantes.The slabs mounted on these frames are generally essentially rigid, and made from materials incorporating a large fraction of plaster. Of such slabs are therefore relatively heavy and bulky.

Par ailleurs, pour aménager des plafonds spéciaux, généralement de grande taille, on a déjà proposé de mettre en place une toile textile de très grandes dimensions, découpée sur mesure à la géométrie de la pièce, et le plus souvent maintenue en position par un système de tendeurs élastiques.In addition, to arrange special ceilings, generally large size, we have already proposed to set up a very large textile canvas dimensions, cut to measure to the geometry of the part, and most often held in position by a system of elastic tensioners.

Une telle réalisation, si elle offre l'avantage d'être esthétique, présente en revanche les inconvénients inhérents aux réalisations spécifiques sur mesure.Such an achievement, if it offers the advantage of being aesthetic, presents in however the disadvantages inherent in specific tailor-made realizations.

En effet, la mise en place d'un tel faux plafond nécessite une visite préalable à la fabrication de la toile textile, ainsi que les opérations de découpe uniques. Indeed, the installation of such a false ceiling requires a prior visit to the manufacture of the textile fabric, as well as the unique cutting operations.

Il est donc impossible d'automatiser et de réaliser en grand nombre, des toiles de grandes dimensions, puisqu'il est indispensable de procéder à une découpe particulière suite à l'intervention de métrage de la pièce. L'ensemble de ces inconvénients se traduit par un prix de revient élevé de faux plafonds réalisés en toile tendue.It is therefore impossible to automate and produce large numbers of fabrics large dimensions, since it is essential to cut particular following the intervention of footage of the piece. All of these disadvantages results in a high cost price of false ceilings made in stretched canvas.

L'invention se propose de fournir une structure de faux plafond qui allie les avantages pratiques de la mise en place des faux plafonds en dalles rigides, tout en conservant l'aspect esthétique flatteur des faux plafonds en toile tendue.The invention proposes to provide a false ceiling structure which combines the practical advantages of installing false ceilings in rigid tiles, while retaining the flattering aesthetic appearance of stretch canvas suspended ceilings.

Exposé de l'inventionStatement of the invention

L'invention concerne donc une dalle destinée à être montée dans un châssis porteur d'une structure de faux plafond.The invention therefore relates to a slab intended to be mounted in a chassis bearing a false ceiling structure.

Cette dalle se caractérise en ce qu'elle est constituée :

  • d'une feuille textile de forme polygonale,
  • d'une pluralité d'éléments périphériques solidarisés à la feuille textile au niveau des angles de ladite feuille,
  • d'un ensemble de tiges bandées entre deux éléments périphériques diamétralement opposés.
This slab is characterized in that it consists of:
  • a polygonal textile sheet,
  • a plurality of peripheral elements secured to the textile sheet at the corners of said sheet,
  • a set of rods banded between two diametrically opposed peripheral elements.

Autrement dit, les dalles conformes à l'invention sont des dalles de surface unitaire dont la quantité nécessaire pour couvrir le plafond peut être déterminée lors de la pose de ce faux plafond, sans visite préalable obligatoire.In other words, the tiles according to the invention are surface tiles unit of which the quantity necessary to cover the ceiling can be determined during the installation of this false ceiling, without compulsory prior visit.

De telles dalles sont réalisées en textile tendu et présentent donc les avantages esthétiques et fonctionnels de l'utilisation de textiles.Such tiles are made of stretched textile and therefore have the advantages aesthetic and functional use of textiles.

En pratique, les dalles sont préférentiellement de forme carrée, voire rectangulaire, mais dans certaines réalisations particulières, d'autres formes polygonales pourraient être adoptées sans sortir du cadre de l'invention.In practice, the tiles are preferably square, or even rectangular, but in some particular realizations, other shapes polygonal could be adopted without departing from the scope of the invention.

Avantageusement en pratique, la feuille textile peut comporter plusieurs couches de natures différentes permettant de combiner différentes propriétés propres à chaque couche. Advantageously in practice, the textile sheet may comprise several layers of different natures allowing to combine different properties specific to each layer.

Ainsi, une feuille textile ajourée peut être associée avec un tissu opaque, de manière à faire ressortir à l'éclairage la nature ajourée de la feuille visible.Thus, an openwork textile sheet can be associated with an opaque fabric, of so as to bring to light the openwork nature of the visible sheet.

Dans une autre application, la feuille textile peut inclure une couche de mousse destinée à assurer une isolation thermique ou phonique.In another application, the textile sheet may include a layer of foam intended to provide thermal or sound insulation.

Dans une autre famille d'application, la feuille textile peut inclure un tissu conducteur de l'électricité, de sorte à servir de source de chaleur lorsqu'elle est convenablement alimentée.In another family of applications, the textile sheet may include a fabric conductor of electricity, so as to serve as a heat source when it is suitably supplied.

Selon une autre caractéristique de l'invention, chaque élément périphérique présente une forme d'équerre ou de triangle, et est disposé au niveau d'un angle de la feuille textile.According to another characteristic of the invention, each peripheral element has a square or triangle shape, and is arranged at an angle of the textile sheet.

De la sorte, les extrémités de chaque côté de la feuille textile sont fermement maintenues pour assurer une mise sous tension optimale grâce aux tiges bandées.In this way, the ends of each side of the textile sheet are firmly maintained to ensure optimum tensioning thanks to the banded rods.

Avantageusement en pratique, chaque élément périphérique comporte des moyens de pincement de la feuille textile, de sorte que les dalles peuvent être assemblées à la demande, au fur et à mesure de la couverture du faux plafond.Advantageously in practice, each peripheral element comprises means for pinching the textile sheet, so that the tiles can be assembled on demand, as the false ceiling is covered.

Le stockage des feuilles textiles indépendamment des éléments périphériques s'avère également avantageux en terme d'encombrement.Storage of textile sheets independently of peripheral elements is also advantageous in terms of space.

Dans une première forme de réalisation, l'élément périphérique comporte :

  • une mâchoire comprenant :
    • une face d'appui,
    • deux faces latérales reliées à la face d'appui venant en regard des bordures de la feuille textile,
    • deux rebords reliés chacun à une face latérale, et orientés en direction de la face d'appui, et destinés à venir au contact de la feuille textile à proximité de ses bordures ;
  • un coin apte à s'encastrer dans la mâchoire, et présentant :
    • une première face destinée à venir au contact de la feuille textile pour la plaquer contre les rebords de la mâchoire,
    • une seconde face formant un angle avec ladite première face ;
  • un contre-coin apte à s'encastrer entre la face d'appui de la mâchoire et la seconde face dudit coin, de manière à plaquer ledit coin contre les rebords de la mâchoire en pinçant la feuille textile.
In a first embodiment, the peripheral element comprises:
  • a jaw comprising:
    • a bearing face,
    • two lateral faces connected to the bearing face facing the edges of the textile sheet,
    • two flanges each connected to a lateral face, and oriented in the direction of the bearing face, and intended to come into contact with the textile sheet near its edges;
  • a corner capable of fitting into the jaw, and having:
    • a first face intended to come into contact with the textile sheet to press it against the edges of the jaw,
    • a second face forming an angle with said first face;
  • a counter corner capable of fitting between the bearing face of the jaw and the second face of said corner, so as to press said corner against the edges of the jaw by pinching the textile sheet.

Autrement dit, chaque élément périphérique comporte deux pièces aptes à coulisser l'une par rapport à l'autre, et qui viennent s'encastrer dans une mâchoire de telle sorte que le coin vienne pincer le bord de la feuille textile contre la mâchoire.In other words, each peripheral element comprises two parts capable of slide one relative to the other, and which come to be embedded in a jaw so that the corner comes to pinch the edge of the textile sheet against the jaw.

Le contre-coin est maintenu en place par l'effort exercé par la tige bandée, ce qui assure un pincement permanent de la feuille textile.The counter wedge is held in place by the force exerted by the banded rod, this which ensures a permanent pinching of the textile sheet.

Dans une forme particulière de réalisation, la première face du coin sur laquelle vient le tissu, comporte des nervures situées en regard des rebords de la mâchoire. De la sorte, les rebords de la mâchoire viennent légèrement pénétrer à l'intérieur de ces nervures pour assurer encore un pincement plus efficace de la feuille textile.In a particular embodiment, the first face of the corner on which comes the fabric, has ribs located opposite the edges of the jaw. In this way, the edges of the jaw penetrate slightly at the inside of these ribs to further ensure more effective pinching of the textile sheet.

Avantageusement en pratique, le coin et le contre-coin comportent des moyens de guidage de leur déplacement relatif.Advantageously in practice, the wedge and the counter wedge include means for guiding their relative displacement.

De la sorte, lorsque le contre-coin est mis en place à l'intérieur de la mâchoire, son déplacement s'effectue obligatoirement selon une diagonale de la feuille textile, ou la bissectrice de l'angle que forment les deux rebords de la mâchoire.In this way, when the counter corner is placed inside the jaw, it must move along a diagonal of the textile sheet, or the bisector of the angle formed by the two edges of the jaw.

Avantageusement en pratique, ces moyens de guidage peuvent être constitués par une nervure et une rainure complémentaire disposées sur le coin et le contre-coin.Advantageously in practice, these guide means can be constituted by a rib and a complementary groove arranged on the corner and the counter corner.

Dans une forme particulière de réalisation, la mâchoire est réalisée en métal, de sorte que son épaisseur peut être fortement limitée, et que par conséquent, la fraction de l'élément périphérique situé en dessous du tissu est extrêmement faible. In a particular embodiment, the jaw is made of metal, so that its thickness can be greatly limited, and therefore the fraction of the peripheral element located below the tissue is extremely small.

Ainsi, lorsque les dalles sont mises en place dans le châssis porteur, il n'y a pratiquement pas de différence de hauteur entre la feuille textile et le châssis proprement dit.When the slabs are placed in the supporting frame, there is no practically no difference in height between the textile sheet and the frame well said.

Bien évidemment, un tel élément périphérique peut être décliné dans de multiples géométries, et n'est pas limité à la seule forme de dalles rectangulaires ou carrées, mais il est possible d'adapter un tel élément pour des angles différents de 90°, voire encore des formes courbes.Obviously, such a peripheral element can be declined in multiple geometries, and is not limited to the single form of rectangular slabs or square, but it is possible to adapt such an element for angles other than 90 °, or even curved shapes.

Dans certaines applications, il peut s'avérer intéressant d'associer différents éléments périphériques conformes à l'invention pour permettre l'aboutage de dalles de manière à former une superficie plus importante composée de plusieurs dalles.In some applications, it may be interesting to combine different peripheral elements according to the invention to allow the joining of slabs so as to form a larger area composed of several slabs.

Dans une autre forme particulière de réalisation, les moyens de pincement de l'élément périphérique sont constitués par :

  • une rainure destinée à recevoir un bord de la feuille textile,
  • une languette articulée par rapport à un bord de la rainure, et mobile entre deux positions, à savoir une position escamotée dans laquelle elle se trouve à l'extérieur de la rainure, et une position de verrouillage dans laquelle elle se trouve à l'intérieur de la rainure et bloque le tissu.
In another particular embodiment, the clamping means of the peripheral element consist of:
  • a groove intended to receive an edge of the textile sheet,
  • a tongue articulated relative to an edge of the groove, and movable between two positions, namely a retracted position in which it is located outside the groove, and a locking position in which it is located inside of the groove and blocks the fabric.

Autrement dit, selon ce mode de réalisation, la languette assure une force de pression suffisante pour éviter l'arrachement du tissu hors de la nervure.In other words, according to this embodiment, the tongue provides a force of enough pressure to prevent the tissue from being pulled out of the rib.

Les moyens de pincement sont adaptables sur différentes épaisseurs de feuille textile, et dans le cas où le tissu est relativement épais et ajouré, le blocage est encore amélioré par la coopération de la languette avec le fil du tissu avec lequel elle est en contactThe pinching means are adaptable to different sheet thicknesses textile, and in the case where the fabric is relatively thick and openwork, the blocking is further improved by the cooperation of the tongue with the thread of the fabric with which she is in touch

En pratique, chaque élément périphérique comporte un logement de réception d'une extrémité de la tige, permettant un montage aisé et durable de la tige en travers de la dalle. In practice, each peripheral element includes a reception housing one end of the rod, allowing easy and durable mounting of the rod in across the slab.

Dans une forme de réalisation particulière, au moins un des éléments périphériques comporte des moyens de réglage de la tension exercée par la tige bandée. En effet, dans certaines applications, il peut s'avérer intéressant d'ajuster la force de tension exercée par la déformation des tiges.In a particular embodiment, at least one of the elements peripherals includes means for adjusting the tension exerted by the rod bandaged. Indeed, in some applications, it may be interesting to adjust the tension force exerted by the deformation of the rods.

Pour des applications particulières, la dalle peut comporter en outre un tirant coopérant d'une part, avec les tiges au niveau de leur zone de croisement, et d'autre part, avec la feuille textile, de manière à conférer à ladite feuille une forme convexe en direction des tiges.For particular applications, the slab may also include a tie rod cooperating on the one hand, with the rods at their crossing zone, and on the other share, with the textile sheet, so as to give said sheet a shape convex towards the rods.

De la sorte, chaque dalle épouse une forme quasi conique particulièrement recherchée en acoustique puisque la surface développée d'une telle dalle est supérieure à la surface carrée projetée. On augmente les phénomènes d'absorption car les angles d'incidence sont atténués, ce qui est favorable à l'atténuation des ondes sonores.In this way, each slab takes on an almost conical shape, particularly sought after in acoustics since the developed surface of such a slab is greater than the projected square area. We increase absorption phenomena because the angles of incidence are attenuated, which is favorable to the attenuation of sound waves.

En outre, une telle géométrie confère un aspect esthétique attractif.In addition, such a geometry gives an attractive aesthetic appearance.

La géométrie inverse peut être adoptée dans la forme de réalisation dans laquelle la dalle comporte en outre une flèche coopérant d'une part, avec les tiges au niveau de leur zone de croisement, et d'autre part, avec la feuille textile au niveau de son centre, de manière à conférer à la feuille textile une forme concave en direction des tiges.The reverse geometry can be adopted in the embodiment in which the slab further comprises an arrow cooperating on the one hand, with the rods at their crossing zone, and on the other hand, with the textile sheet at level of its center, so as to give the textile sheet a concave shape towards the rods.

Dans ce cas, le centre de la feuille textile est repoussé de sa position de repos située dans le plan défini par les éléments périphériques. Une telle géométrie est, pour les mêmes raisons qu'énoncées précédemment, appréciée pour ses propriétés acoustiques.In this case, the center of the textile sheet is pushed back from its rest position located in the plane defined by the peripheral elements. Such geometry is, for the same reasons as stated above, appreciated for its properties acoustic.

Bien entendu, les faux plafonds peuvent être équipés des deux types de dalles particulières précitées, qui peuvent être mixés, notamment en quinconce pour certaines applications. Of course, false ceilings can be fitted with two types of tiles particular aforementioned, which can be mixed, in particular in staggered rows to some applications.

    • Manière de réaliser l'inventionWay of realizing the invention

    Comme déjà dit, l'invention concerne une nouvelle structure de dalle destinée à équiper des faux plafonds, dans laquelle la face principale est constituée d'une feuille textile.As already said, the invention relates to a new slab structure intended to be fitted with false ceilings, in which the main face consists of a textile sheet.

    La géométrie de telles dalles peut être extrêmement variée, n'est en aucun cas limitée à la forme carrée telle qu'illustrée dans les figures annexées.The geometry of such slabs can be extremely varied, is in no case limited to the square shape as illustrated in the appended figures.

    Plus précisément, et comme illustré à la figure 1, la dalle (1) conforme à l'invention est constituée de trois parties essentielles, à savoir :

    • une feuille textile (2) de forme carrée,
    • quatre éléments périphériques (4-7), présentant chacun une forme d'équerre, située à chaque angle de la feuille textile (2),
    • et deux tiges métalliques (8, 9) bandées entre les éléments périphériques (4, 6 ; 5, 7) situés sur une même diagonale, de manière à exercer une tension sur la feuille textile (2), et lui conférer, à la forme illustrée à la figure 1, une géométrie plane.
    More precisely, and as illustrated in FIG. 1, the slab (1) according to the invention consists of three essential parts, namely:
    • a textile sheet (2) of square shape,
    • four peripheral elements (4-7), each having a square shape, located at each corner of the textile sheet (2),
    • and two metal rods (8, 9) bandaged between the peripheral elements (4, 6; 5, 7) located on the same diagonal, so as to exert a tension on the textile sheet (2), and give it shape illustrated in Figure 1, a planar geometry.

    Plus précisément, la feuille textile (2) est équipée dans chacun de ses coins des éléments périphériques (4-7) présentant une forme d'équerre, et dont la face inférieure (10) est destinée à reposer sur un profilé en T (11), tel qu'illustré à la figure 3.More specifically, the textile sheet (2) is equipped in each of its corners peripheral elements (4-7) having a square shape, and the face of which lower (10) is intended to rest on a T-profile (11), as illustrated in the figure 3.

    L'association de tels profilés en T forme un quadrillage définissant des ouvertures carrées à l'intérieur desquelles sont disposées les dalles conformes à l'invention.The association of such T-sections forms a grid defining square openings inside which the tiles conforming to the invention.

    Le châssis constitué de tels profilés en T (11) est suspendu au-dessous du plafond (13) principal au moyen de suspentes (14) ou de tout autre moyen équivalent.The frame made of such T-sections (11) is suspended below the main ceiling (13) by means of hangers (14) or any other means equivalent.

    Chaque élément périphérique (4-7), comme illustré aux figures 4 et 5, est destiné à assurer un pinçage du tissu dans sa zone périphérique, de préférence sans qu'aucun organe ne vienne traverser ou percer le tissu, ce qui constituerait des amorces de déchirure lorsque celui-ci est sous tension.Each peripheral element (4-7), as illustrated in FIGS. 4 and 5, is intended to pinch the tissue in its peripheral zone, preferably without that no organ crosses or pierces the tissue, which would constitute tear primers when it is energized.

    Un tel élément périphérique peut être constitué par l'assemblage des trois éléments illustrés aux figures 4 à 6. Pour plus de clarté, les différents organes de l'élément périphérique ont été montrés de telle sorte qu'ils présentent vers le haut leur face qui sera orientée vers le bas lorsque la dalle sera mise en place pour former le faux-plafond.Such a peripheral element can be constituted by the assembly of the three elements illustrated in Figures 4 to 6. For clarity, the different organs of the peripheral element have been shown so that they show up their face which will face down when the slab is in place for form the false ceiling.

    Ainsi, la feuille textile est représentée sur le dessus de l'élément périphérique alors que lorsque la dalle sera mise en place sur le châssis porteur, la feuille textile sera disposée vers le bas. Thus, the textile sheet is represented on top of the peripheral element while when the slab is placed on the supporting frame, the textile sheet will be laid down.

    Plus précisément, l'élément périphérique comprend comme illustré à la figure 4, une mâchoire (20), qui présente essentiellement une face d'appui (21), de forme illustrée trapézoïdale, mais qui peut épouser d'autres formes, pour autant qu'elle constitue un appui suffisant au coin et au contre-coin.More specifically, the peripheral element comprises as illustrated in the figure 4, a jaw (20), which essentially has a bearing face (21), of form illustrated trapezoidal, but which can take other forms, as long as it provides sufficient support at the corner and counter corner.

    Cette face d'appui se prolonge latéralement par deux faces latérales (22, 23), qui lui sont perpendiculaires. Ces faces latérales (22, 23) viennent en regard des lisières de la feuille textile (2). Chacune de ces faces latérales (22, 23) présente un rebord (24, 25) orienté en direction de la face d'appui (21), et dont l'extrémité (26, 27) est destinée à venir au contact de la feuille textile, et préférentiellement entre deux fils pour assurer un ancrage efficace.This bearing face is extended laterally by two lateral faces (22, 23), which are perpendicular to it. These lateral faces (22, 23) come opposite the edges of the textile sheet (2). Each of these side faces (22, 23) has a rim (24, 25) oriented towards the bearing face (21), and whose end (26, 27) is intended to come into contact with the textile sheet, and preferably between two wires to ensure effective anchoring.

    La mâchoire (20) est réalisée en un matériau métallique tel que l'acier inoxydable.The jaw (20) is made of a metallic material such as steel stainless.

    L'avantage d'utiliser un matériau métallique est de minimiser l'épaisseur des rebords (25, 26) qui sont les seules parties de l'élément périphérique à être situées sur la face inférieure de la feuille textile lorsque celle-ci est mise en place dans le faux-plafond.The advantage of using a metallic material is to minimize the thickness of the ledges (25, 26) which are the only parts of the peripheral element to be located on the underside of the textile sheet when it is placed in the false ceiling.

    Cette mâchoire (20) est destinée à accueillir le coin (30) illustré à la figure (5). Ce coin (30) présente une forme générale, vu de dessus, de triangle rectangle isocèle, dans le cas le plus fréquent où la dalle est de forme carrée ou rectangulaire, mais cette forme pourrait varier en fonction de celle de la dalle.This jaw (20) is intended to accommodate the corner (30) illustrated in the figure (5). This corner (30) has a general shape, seen from above, of a right triangle isosceles, in the most frequent case where the slab is square or rectangular, but this shape could vary depending on that of the slab.

    Le coin (30) présente une première face (31) qui est destinée à venir en contact de la feuille textile (2) de manière à venir la plaquer contre les rebords (24, 25) de la mâchoire (20).The corner (30) has a first face (31) which is intended to come in contact of the textile sheet (2) so as to press it against the edges (24, 25) of the jaw (20).

    A cet effet, la première face (31) du coin (30) peut comporter des rainures (33, 34) parallèles aux côtés à angle droit du coin. Ces deux rainures (33, 34) sont situées à une distance des côtés du coin sensiblement égale à la distance qui sépare les arêtes (26, 27) des rebords (24, 25) par rapport aux faces latérales (22, 23) de la mâchoire (20). To this end, the first face (31) of the corner (30) may have grooves (33, 34) parallel to the right-angled sides of the corner. These two grooves (33, 34) are located at a distance from the sides of the corner substantially equal to the distance between the edges (26, 27) of the flanges (24, 25) relative to the lateral faces (22, 23) of the jaw (20).

    De la sorte, les arêtes (26, 27) se trouvent à l'aplomb des nervures (33, 34) lorsque le coin est mis en place dans la mâchoire, et le tissu y est donc légèrement emprisonné. Il s'ensuit que les risques de glissement du tissu ou de sortie de l'élément périphérique sont très nettement réduits, voire inexistants, pour la quasi majorité des types de tissu.In this way, the edges (26, 27) lie at the base of the ribs (33, 34) when the wedge is placed in the jaw, and the tissue is therefore slightly there imprisoned. It follows that the risks of fabric slipping or coming out of the peripheral element are very clearly reduced, even non-existent, for almost majority of tissue types.

    Le coin (30) présente une seconde face (32) qui présente une certaine inclinaison par rapport à la première face (31), de sorte que l'épaisseur du coin est supérieure au niveau de son angle droit (35) par rapport à son hypoténuse (36).The corner (30) has a second face (32) which has a certain inclination with respect to the first face (31), so that the thickness of the corner is greater than the level of its right angle (35) relative to its hypotenuse (36).

    De la sorte, l'espace situé entre cette face inférieure (32) et la face d'appui (21) de la mâchoire lorsque le coin (30) y est encastré, présente également une épaisseur variable, destinée à accueillir le contre-coin (40) illustré à la figure 6.In this way, the space located between this lower face (32) and the bearing face (21) of the jaw when the wedge (30) is embedded therein, also has a variable thickness, intended to accommodate the counter corner (40) illustrated in FIG. 6.

    Un tel contre-coin (40) présente une épaisseur telle que lorsque sa face (41) coulisse contre la face (32) du coin (30), la face (42) du contre-coin (40) finit par venir au contact de la surface d'appui (21) de la mâchoire, et plaque donc la feuille textile (2) contre les rebords (24, 25) de la mâchoire.Such a counter corner (40) has a thickness such that when its face (41) slides against the face (32) of the wedge (30), the face (42) of the counter wedge (40) ends by come into contact with the bearing surface (21) of the jaw, and therefore plate the sheet textile (2) against the edges (24, 25) of the jaw.

    Le mouvement de déplacement du contre-coin par rapport au coin est guidé grâce à la nervure médiane (43), qui vient coulisser dans la rainure (36) prévue à cet effet sur la face (32) du coin (30).The movement of movement of the counter corner with respect to the corner is guided thanks to the middle rib (43), which slides in the groove (36) provided at this effect on the face (32) of the corner (30).

    Le maintien en position du contre-coin (40) par rapport au coin (30) s'effectue grâce à l'effort exercé par la tige (8, 9) qui vient prendre appui sur le contre-coin (40), au niveau d'un logement (46) prévu à cet effet.The counter-corner (40) is kept in position relative to the corner (30). thanks to the force exerted by the rod (8, 9) which comes to bear on the counter wedge (40), at a housing (46) provided for this purpose.

    De la sorte, le contre-coin (40) reste bloqué dans cette position encastré à l'intérieur de la mâchoire, ce qui maintient donc l'effort de pinçage exercé sur la feuille textile par les rebords (24, 25) de la mâchoire (20).In this way, the counter wedge (40) remains locked in this recessed position at inside the jaw, which therefore maintains the clamping force exerted on the textile sheet by the edges (24, 25) of the jaw (20).

    Bien évidemment, le coin (30) et le contre-coin (40) peuvent être constitués de matériaux très variés, notamment en matières plastiques telles que le polypropylène, le polychlorure de vinyle, le polyamide qui sont avantageusement légères. Obviously, the wedge (30) and the counter wedge (40) can be formed of a wide variety of materials, especially plastics such as polypropylene, polyvinyl chloride, polyamide which are advantageously light.

    De par la conception et la simplicité de cet élément périphérique, on conçoit la possibilité d'associer plusieurs de ces éléments périphériques, au niveau des faces latérales des mâchoires (22, 23) par exemple pour former une zone de jonction entre plusieurs feuilles textiles, et réaliser ainsi un aboutage.By the design and the simplicity of this peripheral element, we conceive the possibility of associating several of these peripheral elements, at the level of lateral faces of the jaws (22, 23) for example to form a zone of junction between several textile sheets, and thus achieve a butting.

    La très faible épaisseur des faces latérales de la mâchoire permet de rapprocher très fortement les feuilles textiles adjacentes, de manière à assurer un aboutage quasi parfait.The very small thickness of the side faces of the jaw allows bring the adjacent textile sheets very close together, so as to ensure almost perfect butting.

    Ainsi, selon une autre variante de réalisation, un élément périphérique peut être constitué d'un profilé, ou comme illustré de façon exemplative, par l'association de deux profilés.Thus, according to another alternative embodiment, a peripheral element can be made of a profile, or as illustrated by way of example, by the combination of two profiles.

    Ainsi, comme illustré à la figure 8, l'élément périphérique comprend un premier profilé (50) en forme de U, formant pièce extérieure, et comportant une gorge (51) recevant un second profilé (55) plus fin.Thus, as illustrated in FIG. 8, the peripheral element comprises a first U-shaped profile (50), forming an external part, and comprising a groove (51) receiving a second thinner section (55).

    La face inférieure (52) du profilé extérieur en U est destinée à reposer sur le profilé en T (11) du châssis.The underside (52) of the outer U-shaped profile is intended to rest on the T-profile (11) of the chassis.

    La gorge (51) de ce profilé en U (50) reçoit le second profilé (55) destiné à assurer la fonction de pinçage du tissu.The groove (51) of this U-shaped profile (50) receives the second profile (55) intended to perform the pinching function of the fabric.

    Dans une forme différente de réalisation non représentée, les éléments périphériques peuvent être réalisés par un seul et unique élément profilé.In a different embodiment not shown, the elements peripherals can be realized by a single profiled element.

    S'agissant du profilé intérieur (55) illustré à la figure 8, ce dernier comporte essentiellement une rainure (56) et une languette articulée (57).Regarding the inner profile (55) illustrated in Figure 8, the latter comprises essentially a groove (56) and an articulated tongue (57).

    La rainure (56), parallèle à la gorge (51) du profilé extérieur (50), est destinée à recevoir un bord de la feuille textile (2).The groove (56), parallel to the groove (51) of the outer profile (50), is intended to receive an edge of the textile sheet (2).

    La languette (57) est articulée par rapport à un bord de la rainure (56), et plus précisément par rapport à la paroi (58) formant la partie supérieure du profilé interne (50). The tongue (57) is articulated relative to an edge of the groove (56), and more precisely with respect to the wall (58) forming the upper part of the profile internal (50).

    Cette articulation est obtenue par une zone (59) de moindre épaisseur et permet le pivotement de la languette (57) entre deux positions.This articulation is obtained by a zone (59) of lesser thickness and allows pivoting of the tongue (57) between two positions.

    Ainsi, comme illustré à la figure 8, la zone externe (50) du profilé (55) de pinçage relevée, de sorte que la languette (57) est située en position escamotée, et se trouve à l'extérieur de la rainure (56).Thus, as illustrated in FIG. 8, the external zone (50) of the profile (55) of pinching up, so that the tongue (57) is located in the retracted position, and is located outside the groove (56).

    A l'opposé, comme illustré à la figure 9, la zone externe du profilé (50) est pivotée de telle sorte que la languette (57) se retrouve à l'intérieur de la nervure (56), et orientée en direction de l'intérieur de la nervure (56).In contrast, as illustrated in FIG. 9, the external zone of the profile (50) is pivoted so that the tongue (57) is inside the rib (56), and oriented towards the interior of the rib (56).

    Ainsi, la languette (57) assure un pincement du tissu sur la paroi opposée (52) du profilé interne (51), et l'orientation de la languette (57) forme un arc boutant s'opposant à la sortie du tissu.Thus, the tongue (57) pinches the fabric on the opposite wall (52) of the internal profile (51), and the orientation of the tongue (57) forms a flying arc opposing the exit of the fabric.

    Le verrouillage du tissu est encore amélioré dans le cas où la feuille textile (2) comprend une structure ajourée dans laquelle les fils de chaíne ou de trame sont relativement écartés les uns des autres, tels que notamment par exemple pour les tissus techniques commercialisés sous la marque BATYLINE® .The locking of the fabric is further improved in the case where the textile sheet (2) includes an openwork structure in which the warp or weft threads are relatively far apart from each other, such as in particular for example for technical fabrics sold under the BATYLINE® brand.

    Dans ce cas, un fil particulier (65) du tissu, de relativement fort diamètre vient coopérer avec l'extrémité de la languette (57) et assure un blocage précis et ferme en position du tissu.In this case, a particular wire (65) of the fabric, of relatively large diameter cooperates with the end of the tongue (57) and ensures precise locking and closes in position of the fabric.

    Comme illustré aux figures 8 et 9, la zone extérieure (60) du profilé interne (55) comporte également, au-delà de la languette (57), une zone galbée (64) destinée à venir en appui sur le tissu lorsque celui-ci est en position pincée, de manière à assurer une régularité de la tension périphérique du tissu.As illustrated in Figures 8 and 9, the outer area (60) of the internal profile (55) also comprises, beyond the tongue (57), a curved zone (64) intended to come to bear on the fabric when the latter is in the pinched position, so as to ensure regularity of the peripheral tension of the tissue.

    Cette zone extérieure (60) sert également d'appui à l'utilisateur pour provoquer le pivotement de la languette.This outer area (60) also serves as support for the user to cause the tongue to pivot.

    Bien évidemment, l'invention ne se limite pas à la forme d'élément périphérique illustrée, mais couvre toutes variantes dans lesquelles le tissu est pincé par tout moyen approprié dans sa zone périphérique. En effet, un des intérêts de l'invention est de permettre une mise en place facile des éléments périphériques autour de la feuille de tissu, et ce à la demande, au fur et à mesure de la mise en place des éléments dans le châssis porteur.Obviously, the invention is not limited to the form of element device illustrated, but covers all variants in which the fabric is pinched by any appropriate means in its peripheral zone. One of the interests of the invention is to allow easy installation of the peripheral elements around the sheet of fabric, and this on demand, as the setting places elements in the supporting frame.

    Selon une autre caractéristique de l'invention, la dalle (1) comporte des tiges (8, 9) de mise sous tension du tissu. Ces tiges (8, 9) coopèrent avec les éléments périphériques (4-7) au niveau de gorges ou de logements (46) prévus à cet effet.According to another characteristic of the invention, the slab (1) comprises rods (8, 9) for tensioning the fabric. These rods (8, 9) cooperate with the elements peripherals (4-7) at the level of grooves or housings (46) provided for this purpose.

    De tels logements (46) peuvent avantageusement être disposés sur le contre-coin (40) ou à la zone de jonction des deux branches de l'équerre de l'élément périphérique illustrée à la figure 8.Such housings (46) can advantageously be arranged on the counter wedge (40) or at the junction of the two branches of the element's square device shown in Figure 8.

    Ce logement (46) présente une inclinaison (α) par rapport au plan principal de la dalle (1), de manière à ce que les tiges (8, 9) qu'il accueille soient cintrées pour exercer une force de traction tendant le tissu.This housing (46) has an inclination (α) relative to the main plane of the slab (1), so that the rods (8, 9) which it receives are bent to exert a tensile force stretching the fabric.

    L'inclinaison (α) est déterminée de façon à ce que la tension sur le tissu soit suffisante pour que ce dernier soit effectivement plan et n'adopte aucune courbure due à son propre poids.The inclination (α) is determined so that the tension on the fabric is sufficient for the latter to be effectively planar and to adopt no curvature due to its own weight.

    Dans certaines formes de réalisation, on peut prévoir que les logements (46) recevant les extrémités des tiges (8, 9) sont équipés de moyens permettant de régler plus finement la tension de la tige.In certain embodiments, provision may be made for the housings (46) receiving the ends of the rods (8, 9) are equipped with means for adjusting more finely the tension of the rod.

    Néanmoins, dans des formes simplifiées, les tiges sont conçues de telle sorte qu'un tel réglage soit inutile.However, in simplified forms, the rods are designed so that such adjustment is unnecessary.

    Par ailleurs, la longueur de chaque branche de l'élément périphérique est également déterminée pour éviter un affaissement du centre et des bords de la feuille textile due à son propre poids.Furthermore, the length of each branch of the peripheral element is also determined to avoid sagging of the center and edges of the textile sheet due to its own weight.

    En pratique, on a obtenu de bons résultats en utilisant des feuilles textiles (2) de forme carrée, de 600 mm de côté, et d'un poids de 500 g au mètre carré.In practice, good results have been obtained using textile sheets (2) square in shape, 600 mm per side, and weighing 500 g per square meter.

    Les éléments périphériques (4-7) présentent une longueur de l'ordre de 80 mm, et les tiges (8, 9) utilisées sont des tiges cylindriques en acier, d'un diamètre voisin de 6 mm. The peripheral elements (4-7) have a length of the order of 80 mm, and the rods (8, 9) used are cylindrical steel rods, of a diameter close to 6 mm.

    La tension exercée sur le tissu est suffisante pour une inclinaison (α) des tiges (8, 9) au niveau des éléments périphériques (4-7) de l'ordre de 15°.The tension exerted on the fabric is sufficient for an inclination (α) of the rods (8, 9) at the level of the peripheral elements (4-7) of the order of 15 °.

    L'invention couvre également des variantes de réalisation telles qu'illustrées aux figures 10 et 11, dans lesquelles la feuille textile n'est plus plane, mais au contraire épouse une courbure orientée soit vers le haut, soit vers le bas.The invention also covers alternative embodiments as illustrated Figures 10 and 11, in which the textile sheet is no longer flat, but at contrary marries a curvature oriented either upwards or downwards.

    Ainsi, comme illustré à la figure 10, la dalle (80) comporte un élément supplémentaire constituant un tirant (81), et reliée d'une part, aux tiges (82), au niveau de leur intersection, et d'autre part, coopérant avec la feuille textile (83) en son centre, par l'intermédiaire d'une zone en excroissance (84) traversant un trou (85) ménagé à cet effet au centre de la feuille.Thus, as illustrated in FIG. 10, the slab (80) comprises an element additional constituting a tie rod (81), and connected on the one hand, to the rods (82), to the level of their intersection, and on the other hand, cooperating with the textile sheet (83) in its center, via a protruding zone (84) passing through a hole (85) formed for this purpose in the center of the sheet.

    La longueur de ce tirant (81) est inférieure à la distance qui sépare les tiges (82) de la feuille textile (83) lorsque celle-ci est au repos. De la sorte, le centre de la feuille textile est surélevée par rapport au plan principal de la dalle (80).The length of this tie (81) is less than the distance between the rods (82) of the textile sheet (83) when the latter is at rest. In this way, the center of the textile sheet is raised relative to the main plane of the slab (80).

    Le tirant (81), et la zone centrale de la feuille (83) peuvent être avantageusement équipés de tous moyens permettant d'éviter la dégradation du tissu du fait de la traction supplémentaire exercée.The tie rod (81), and the central zone of the sheet (83) can be advantageously equipped with all means to avoid degradation of the fabric due to the additional traction exerted.

    A l'inverse, la dalle (90) illustrée à la figure 11 présente un élément formant flèche (91), coopérant d'une part, avec les tiges (92) au niveau de leur intersection, et d'autre part, avec le centre de la feuille (93), de manière à repousser vers le bas la zone centrale de la feuille textile en dessous de sa position de repos.Conversely, the slab (90) illustrated in FIG. 11 has an element forming arrow (91), cooperating on the one hand, with the rods (92) at their intersection, and on the other hand, with the center of the sheet (93), so as to push back down the central zone of the textile sheet below its rest position.

    De la sorte, la convexité de la feuille est orientée vers le bas.In this way, the convexity of the sheet is oriented downwards.

    Les agencements appropriés peuvent être prévus au niveau de la zone centrale de la feuille pour assurer un positionnement précis et un blocage en position de l'extrémité basse de la flèche (91) sur la feuille (93).Appropriate arrangements can be provided in the central area sheet to ensure precise positioning and locking in position the lower end of the arrow (91) on the sheet (93).

    La configuration des deux modes de réalisation illustrés aux figures 10 et 11 s'avère particulièrement avantageuse pour ses propriétés acoustiques, puisque les angles d'incidence des ondes sonores sont modifiés, ce qui est propice à l'absorption de l'énergie acoustique. The configuration of the two embodiments illustrated in FIGS. 10 and 11 is particularly advantageous for its acoustic properties, since the sound wave incidence angles are changed, which is conducive to absorption of acoustic energy.

    En outre, la surface de la feuille, et donc ses capacités d'absorption d'énergie est supérieure à la forme de réalisation dans laquelle la feuille est strictement plane.In addition, the surface of the sheet, and therefore its energy absorption capacities is greater than the embodiment in which the sheet is strictly planar.

    Bien évidemment, et comme déjà dit, les différentes formes planes et convexes ou concaves peuvent être agencées de façon associée, pour donner des effets esthétiques et fonctionnels différents.Obviously, and as already said, the different plane shapes and convex or concave can be arranged in an associated manner, to give different aesthetic and functional effects.

    S'agissant de la feuille textile proprement dit, celle-ci peut être extrêmement variable, en fonction des propriétés souhaitées.As far as the textile sheet itself is concerned, this can be extremely variable, depending on the desired properties.

    Ainsi, la feuille textile peut être constituée d'un tissu ajouré tel que notamment celui commercialisé sous la marque BATYLINE® par le Demandeur. Cette feuille textile peut être constituée de plusieurs couches différentes, telles que notamment une couche d'un tissu ajouré, et d'une couche de tissu plus opaque, permettant de rendre la dalle opaque visuellement, tout en lui laissant l'aspect esthétique d'un tissu ajouré.Thus, the textile sheet can consist of an openwork fabric such as in particular that marketed under the BATYLINE® brand by the Applicant. This textile sheet can consist of several different layers, such as in particular a layer of openwork fabric, and a layer of more opaque fabric, allowing to make the slab opaque visually, while leaving it the appearance aesthetic of an openwork fabric.

    La feuille textile peut également incorporer une couche de mousse ou équivalente, utilisée pour ses propriétés d'isolation thermique et/ou phonique.The textile sheet can also incorporate a layer of foam or equivalent, used for its thermal and / or sound insulation properties.

    Par ailleurs, la couleur et les motifs imprimés sur les feuilles textiles peuvent être avantageusement utilisés pour former une signalétique au niveau du faux plafond, pouvant évoluer avec le déplacement ou le remplacement des dalles colorées.In addition, the color and patterns printed on the textile sheets can be advantageously used to form signage at the false ceiling, which can change with the displacement or replacement of tiles colored.

    L'utilisation d'une feuille textile ajourée, ou plus généralement perméable à l'air, s'avère particulièrement avantageuse pour assurer les fonctions d'aération et de climatisation.The use of an openwork textile sheet, or more generally permeable to air is particularly advantageous for ensuring the ventilation functions and air conditioning.

    En effet, le faux plafond constitué de dalles conformes à l'invention, dans lesquelles les feuilles textiles laissent passer l'air, permet une circulation d'air à travers l'intégralité de la surface du faux plafond.Indeed, the false ceiling made up of tiles in accordance with the invention, in which the textile sheets allow air to pass through, allows air circulation to across the entire surface of the false ceiling.

    En d'autres termes, la totalité de la surface du faux plafond sert de bouche d'aération. In other words, the entire surface of the false ceiling serves as a mouth ventilation.

    La superficie d'une telle bouche d'aération permet d'utiliser de l'air circulant à des vitesses très nettement inférieures à celles de l'air circulant dans des conduits d'aération standard.The area of such an air vent allows the use of air circulating at speeds significantly lower than those of air flowing in ducts standard ventilation.

    Ainsi, les bruits de flux peuvent être totalement éliminés et les canalisations d'air circulant dans le faux plafond sont inutiles. Il s'ensuit que la distance entre le plafond proprement dit et le faux plafond peut être nettement réduite puisqu'il n'est plus nécessaire d'y faire circuler des canalisations d'air spécifiques.In this way, the flow noise can be completely eliminated and the pipes air circulating in the false ceiling is useless. It follows that the distance between the ceiling itself and the false ceiling can be significantly reduced since it is not no more need to circulate specific air ducts.

    Une variation de la perméabilité des dalles est adoptée pour assurer une distribution des pertes de charge tel que le débit traversant la surface du faux plafond soit sensiblement uniforme sur l'intégralité de sa surface.A variation in the permeability of the slabs is adopted to ensure a distribution of pressure drops such as the flow through the surface of the false ceiling is substantially uniform over its entire surface.

    Une telle disposition permet en outre d'assurer l'opération de filtration de l'air circulant directement par les dalles et plus précisément leur feuille textile et non plus par des systèmes spécifiques.Such an arrangement also makes it possible to ensure the air filtration operation. flowing directly through the tiles and more precisely their textile sheet and not more by specific systems.

    Dans une forme avantageuse de l'invention, les différentes dalles peuvent en outre, incorporer un tissu chauffant permettant de chauffer l'air qui les traverse, et ainsi assurer une distribution uniforme de chaleur. Dans ce cas, la nature métallique de la mâchoire (20) de l'élément périphérique permet d'assurer une amenée de courant efficace.In an advantageous form of the invention, the various tiles can in addition, incorporate a heating cloth to heat the air passing through them, and thus ensuring a uniform distribution of heat. In this case, nature metal of the jaw (20) of the peripheral element ensures a effective current supply.

    En pratique, les dalles conformes à l'invention peuvent être montées directement sur le chantier. En effet, le montage d'une dalle comprend les opérations de mise en place des quatre éléments périphériques au coin de la feuille textile, puis la mise en place des deux tiges diagonales en travers de la feuille textile.In practice, the tiles according to the invention can be mounted directly on site. Indeed, the mounting of a slab includes the operations of placing the four peripheral elements at the corner of the sheet textile, then placing the two diagonal rods across the sheet textile.

    Il s'ensuit que le stockage des différents éléments destinés à réaliser le faux plafond peut s'assurer de façon indépendante, les feuilles textiles étant stockées indépendamment des éléments périphériques et des tiges. It follows that the storage of the various elements intended to achieve the forgery ceiling can be independently insured, the textile sheets being stored independently of peripheral elements and rods.

    Il ressort de ce qui précède que la structure des dalles de faux plafond conformes à l'invention, présente de multiples avantages et notamment :

    • la facilité de montage,
    • la possibilité de réaliser le faux plafond à partir d'éléments standards, sans nécessiter de visite préalable,
    • la facilité de stockage d'éléments standards destinés à réaliser les dalles,
    • une grande variété dans les formes utilisées,
    • une grande variété dans les natures de textile utilisé, ce qui permet de conférer au faux plafond de très nombreux aspects esthétiques, ainsi que de nombreuses fonctions d'isolation thermique ou phonique,
    • la possibilité de conférer au faux plafond des formes géométriques avec des convexités propices à l'absorption des ondes acoustiques,
    • la possibilité de réaliser des faux plafonds servant de bouche d'aération de superficie très largement supérieure aux bouches unitaires classiques, avec la conséquence de l'élimination des défauts inhérents au système de canalisation d'air tels que les bruits de flux et l'encombrement,
    • la possibilité d'organiser à volonté et très simplement les zones de soufflage de l'air selon les dispositions évolutives de bureau ainsi que les saisons : soufflage d'air frais en été au fond des bureaux, soufflage d'air chaud en hiver prés des fenêtres,
    • la possibilité de réaliser des dalles textiles sans recourir à des matériaux fibreux pouvant polluer la qualité de l'air ambiant.
    It appears from the above that the structure of the false ceiling tiles in accordance with the invention has many advantages, in particular:
    • ease of assembly,
    • the possibility of making the false ceiling from standard elements, without requiring a prior visit,
    • the ease of storing standard elements intended to make the slabs,
    • a great variety in the forms used,
    • a wide variety in the types of textile used, which makes it possible to confer on the false ceiling very many aesthetic aspects, as well as many functions of thermal or sound insulation,
    • the possibility of giving the false ceiling geometric shapes with convexities conducive to the absorption of acoustic waves,
    • the possibility of making false ceilings serving as an air outlet with a surface area much larger than conventional unit outlets, with the consequence of eliminating the defects inherent in the air ducting system such as flow noises and congestion ,
    • the possibility of organizing at will and very simply the air blowing zones according to the evolving office arrangements as well as the seasons: blowing of fresh air in summer at the bottom of the offices, blowing of hot air in winter near Windows,
    • the possibility of making textile tiles without using fibrous materials that can pollute the quality of the ambient air.
