Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention concerne le domaine des structures tridimensionnelles en toiles tendues telles que notamment des fausses-parois, faux-plafonds, faux-murs, ou structures ornementales.The invention relates to the field of three-dimensional structures in stretched fabrics such as in particular false-walls, false ceilings, false walls, or ornamental structures.

L'invention concerne plus particulièrement une lisse lumineuse pour structure tridimensionnelle en toile tendue ainsi qu'une structure tridimensionnelle comprenant une telle lisse sur laquelle une toile tendue est fixée.The invention relates more particularly to a light rail for three-dimensional structure in stretched fabric and a three-dimensional structure comprising such a smooth on which a stretched fabric is fixed.

ETAT DE LA TECHNIQUESTATE OF THE ART

Il est connu du brevet FR2985298 une fausse paroi rétro-éclairée par au moins une source de lumière sous forme de diodes électroluminescentes intégrées à la lisse et constituée d'au moins une nappe souple translucide tendue accrochée par ses bordures pourvues de moyens d'accrochage à un cadre, le cadre étant constitué par une lisse formée de profils aboutés et comprenant des organes de réception aptes à coopérer avec lesdits moyens d'accrochage pour maintenir ladite nappe souple tendue.It is known from the patent FR2985298 a false wall backlit by at least one light source in the form of electroluminescent diodes integrated into the rail and consisting of at least one taut translucent flexible sheet hung by its edges provided with means of attachment to a frame, the frame being constituted by a smooth formed of abutting profiles and comprising receiving members adapted to cooperate with said attachment means for holding said flexible sheet taut.

La lisse décrite dans la demande susmentionnée présente cependant un certain nombre d'inconvénients. La lisse selon l'art antérieur ne permet pas d'obtenir de formes émoussées, circulaires, courbes. De plus, les arrêtes formées par ces lisses sont saillantes ce qui peut être dangereux et disgracieux selon le rendu final désiré. La lisse du document FR2998316 décrit une lisse selon le préambule de la revendication 1.The smooth described in the aforementioned application, however, has a number of disadvantages. The smooth according to the prior art does not allow to obtain blunt forms, circular, curved. In addition, the edges formed by these smooth are salient which can be dangerous and unsightly depending on the desired final result. The smooth of the document FR2998316 describes a bar according to the preamble of claim 1.

L'invention vise à remédier à ces problèmes en proposant une lisse lumineuse pour structure tridimensionnelle rétroéclairée.The invention aims to remedy these problems by proposing a luminous rail for three-dimensional structure backlit.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

A cet effet, et selon un premier aspect, l'invention propose une lisse pour structure tridimensionnelle en toiles tendues comprenant au moins une source lumineuse intégrée à la lisse. Cette lisse comprend deux évidements contigus séparés par une langue destinés à recevoir les éléments de fixation des toiles tendues, chaque évidemment comportant un fond, une paroi latérale interne formant la langue et une paroi latérale externe, chaque paroi latérale externe définissant une aile périphérique de la lisse.For this purpose, and according to a first aspect, the invention proposes a rail for three-dimensional structure in stretched canvases comprising at least one light source integrated into the stringer. This rail comprises two contiguous recesses separated by a tongue for receiving the fastening elements of the stretched cloths, each obviously having a bottom, an inner side wall forming the tongue and an outer side wall, each outer side wall defining a peripheral wing of the smooth.

Dans la présente demande, on définit d'externe, la paroi latérale de l'évidemment opposée à la paroi latérale de l'évidemment formant la langue, dite paroi latérale interne.In the present application, the external wall is defined as the lateral wall of the recess opposite to the lateral wall of the recess forming the tongue, referred to as the internal lateral wall.

Les lisses sont en tout matériau, par exemple un métal comme l'aluminium, ou un plastique comme le polychlorure de vinyle (PVC).The heddles are of any material, for example a metal such as aluminum, or a plastic such as polyvinyl chloride (PVC).

Les lisses conformément à l'invention sont aboutées pour former des profilés, lesdits profilés participant à l'ossature de la structure tridimensionnelle dans laquelle ces lisses sont utilisées. Les lisses sont invisibles lorsque les toiles tendues sont montées. Cette lisse permet de former des structures tridimensionnelles dont toutes les faces peuvent être visibles, voire ornementées selon le rendu désiré. Cette lisse permet également d'obtenir des formes en courbe ou arrondies ainsi que des arrêtes non saillantes. Ceci a un rendu esthétique parfait et évite tout risque de rupture ou de déchirement de la toile tendue par contact de la toile sur et autour de la lisse. L'usure de la toile tendue est également ralentie. Cette lisse peut également servir pour tendre des toiles pour former un faux plafond mais également une fausse paroi dont les deux faces sont visibles. Egalement, la forme particulière de cette lisse n'entraine pas d'ombre portée lorsque les diodes électroluminescentes sont allumées.The slats according to the invention are abutting to form profiles, said profiles participating in the framework of the three-dimensional structure in which these rails are used. The rails are invisible when the stretched cloths are mounted. This smooth makes it possible to form three-dimensional structures of which all the faces can be visible, even ornamented according to the desired rendering. This bar also makes it possible to obtain curved or rounded shapes as well as non-projecting edges. This has a perfect aesthetic appearance and avoids any risk of rupture or tearing of the canvas stretched by contact of the fabric on and around the rail. The wear of the stretched fabric is also slowed down. This smooth can also be used to stretch webs to form a false ceiling but also a false wall whose two faces are visible. Also, the particular shape of this rail does not cause a drop shadow when the light-emitting diodes are lit.

Les toiles tendues sont de préférence translucides ou apte à transmettre la lumière. Elles peuvent être texturées, colorées, unies, imprimées, peintes, ou présenter tout type d'ornement, y compris comporter des zones ne transmettant pas la lumière afin d'obtenir des jeux d'ombre et lumière.Stretched fabrics are preferably translucent or capable of transmitting light. They can be textured, colored, plain, printed, painted, or have any type of ornament, including non-light transmitting areas for shadows and light.

Les diodes électroluminescentes peuvent être de n'importe quelle couleur et de n'importe quelle puissance.The light emitting diodes can be of any color and any power.

Avantageusement, la lisse lumineuse présente une surface périphérique pourvue d'au moins une encoche d'accueil d'une source lumineuse.Advantageously, the light rail has a peripheral surface provided with at least one receiving notch of a light source.

Selon une configuration particulière, la lisse comporte une encoche d'accueil présentant une ouverture opposée à celle des évidements. Il peut être prévu également que la lisse comporte deux autres encoches d'accueil disposées de part et d'autre de l'encoche présentant une ouverture opposée à celle des évidements. Avantageusement, les encoches d'accueil disposées de part et d'autre de l'encoche présentant une ouverture opposée à celle des évidements sont situées à équidistance de celle-ci.According to a particular configuration, the rail has a receiving notch having an opening opposite to that of the recesses. It may also be provided that the arm has two other receiving notches arranged on either side of the notch having an opening opposite to that of the recesses. Advantageously, the receiving notches arranged on either side of the notch having an opening opposite to that of the recesses are located equidistant therefrom.

Avantageusement, l'aile périphérique de la lisse est raccordée à l'extrémité de la paroi latérale externe de l'évidemment adjacent par une jonction arrondie, la surface externe d'une aile périphérique définissant en section transversale une portion arrondie contre laquelle la toile tendue prend appui pour créer un volume, la surface externe de l'aile opposée intégrant la source lumineuse.Advantageously, the peripheral wing of the beam is connected to the end of the outer lateral wall of the adjacent cavity by a rounded junction, the outer surface of a peripheral wing defining in cross section a rounded portion against which the stretched fabric takes support to create a volume, the outer surface of the opposite wing integrating the light source.

L'on comprend que la lisse comporte deux ailes périphériques : la première aile s'étendant à partir de la jonction arrondie avec la paroi latérale externe d'un évidement, la deuxième s'étendant de la jonction arrondie avec la paroi latérale externe de l'évidement adjacent. Ces deux ailes ne sont pas nécessairement symétriques par rapport à la langue séparant les deux évidements. La surface externe de la première aile définit en section transversale une portion arrondie servant de support à la toile tendue. La forme courbe de cette portion d'aile évite à la toile de se déchirer et permet de créer une diversité plus importante de structure tridimensionnelle et de créer un espace plus important entre les toiles tendues sans risque de cisaillement.It is understood that the rail has two peripheral wings: the first wing extending from the rounded junction with the outer side wall of a recess, the second extending from the rounded junction with the outer side wall of the recess adjacent. These two wings are not necessarily symmetrical with respect to the tongue separating the two recesses. The outer surface of the first wing defines in cross section a rounded portion for supporting the stretched fabric. The curved shape of this wing portion prevents the fabric from tearing and creates a greater diversity of three-dimensional structure and creates more space between the stretched canvases without risk of shearing.

Avantageusement, les ailes périphériques sont agencées pour définir une encoche d'accueil d'une source lumineuse. Dans cette configuration, les ailes périphériques sont avantageusement symétriques par rapport à la langue.Advantageously, the peripheral wings are arranged to define a reception notch of a light source. In this configuration, the peripheral wings are advantageously symmetrical with respect to the tongue.

Lorsque la lisse est de section transversale sensiblement circulaire ou selon un cercle tronqué, alors, cette portion arrondie peut non limitativement s'étendre sur au moins un quart de cercle de rayon sensiblement équivalent à la profondeur des évidements.When the beam is of substantially circular cross section or a truncated circle, then, this rounded portion may not extend beyond at least a quarter circle of radius substantially equivalent to the depth of the recesses.

Selon une alternative, cette portion arrondie s'étend sur au moins un demi cercle de rayon sensiblement équivalent à la profondeur des évidements.According to an alternative, this rounded portion extends over at least one half circle of radius substantially equivalent to the depth of the recesses.

Selon une autre alternative, cette portion arrondie s'étend sur ¾ d'un cercle de rayon sensiblement équivalent à la profondeur des évidements.According to another alternative, this rounded portion extends over ¾ of a circle of radius substantially equivalent to the depth of the recesses.

Selon un mode de réalisation, l'aile périphérique opposée à l'aile support d'une toile tendue comporte une encoche d'accueil d'au moins une source lumineuse.According to one embodiment, the peripheral wing opposite the support wing of a stretched fabric comprises a notch for receiving at least one light source.

L'on comprend que l'encoche comprend le système d'alimentation de la source lumineuse ainsi que la ou les sources lumineuses.It is understood that the notch comprises the supply system of the light source and the light source or sources.

Selon une variante, l'encoche d'accueil est de forme complémentaire d'au moins une portion latérale de la source lumineuse de façon à ce que la source lumineuse s'inscrive dans le contour de la lisse en section transversale.According to one variant, the receiving notch is of complementary shape to at least one lateral portion of the light source so that the light source fits into the contour of the cross-sectional bar.

Dans un mode de réalisation, l'encoche forme un angle droit.In one embodiment, the notch forms a right angle.

La source lumineuse est un néon, une fibre optique ou tout autre source lumineuse connue de l'Homme du métier. Préférentiellement, la source lumineuse est constituée par des diodes électroluminescentes intégrées à la lisse.The light source is a neon, an optical fiber or any other light source known to those skilled in the art. Preferably, the light source is constituted by electroluminescent diodes integrated into the beam.

Selon un mode préféré de réalisation de l'invention, les évidements contigus et l'encoche de la lisse sont disposés dans des plans parallèles les uns aux autres.According to a preferred embodiment of the invention, the contiguous recesses and the notch of the bar are arranged in planes parallel to one another.

Cet agencement particulier des évidements permet de tendre une ou deux toiles. Lorsque deux toiles sont montées, une toile tendue fixée par évidement, l'une peut envelopper partiellement la lisse, par exemple sur 180°, l'autre peut être tendue parallèlement à la première toile, délimitant un espace entre les deux toiles de la hauteur de la lisse. La source lumineuse est disposée préférentiellement vers l'espace intertoile, ce qui évite toute ombre portée de la lisse sur les toiles tendues. L'on comprend évidemment que l'espace entre les deux toiles peut être supérieur ou égal à la hauteur de la lisse selon la forme de la structure tridimensionnelle finale. Cet espace peut s'agrandir à mesure que la distance avec la lisse augmente.This particular arrangement of the recesses allows to stretch one or two canvases. When two canvases are mounted, a stretched canvas fixed by recess, one can partially wrap the smooth, for example 180 °, the other can be stretched parallel to the first fabric, delimiting a space between the two canvases height of the smooth. The light source is preferentially disposed towards the inter-ear space, which avoids any shadows of the beam on the stretched canvases. It is of course understood that the space between the two webs may be greater than or equal to the height of the rail according to the shape of the final three-dimensional structure. This space can expand as the distance to the rail increases.

Selon un mode préféré de réalisation, les évidements contigus séparés par une langue comportent des épaulements de rétention des éléments de fixation des toiles tendues, lesdits épaulements étant sur les parois latérales externes des évidements et/ou sur chaque face de la lange.According to a preferred embodiment, the contiguous recesses separated by a tongue comprise shoulders for retaining the fastening elements of the stretched cloths, said shoulders being on the outer side walls of the recesses and / or on each side of the cloth.

Selon une variante néanmoins préférée de réalisation, les épaulements de la paroi latérale externe des évidements sont disposés en vis-à-vis par rapport aux épaulements des parois de la langue.According to a nonetheless preferred embodiment, the shoulders of the outer side wall of the recesses are arranged vis-a-vis with respect to the shoulders of the walls of the tongue.

L'on comprend que les évidements comprennent sur les parois des épaulements formant des butées de rétention pour fixer les toiles tendues. Les toiles tendues comportent des éléments de fixation tels des crochets ou tout autre moyen connu de l'Homme du métier permettant d'accrocher la toile dans les lisses et de les tendre.It is understood that the recesses comprise on the walls of the shoulders forming retention stops to fix the stretched cloths. Stretched cloths comprise fastening elements such as hooks or any other means known to those skilled in the art to hang the fabric in the rails and tension them.

L'invention porte également sur une structure tridimensionnelle lumineuse comportant au moins un profilé constitué de lisses lumineuses aboutées et recouvert de toiles tendues.The invention also relates to a three-dimensional luminous structure comprising at least one section consisting of smooth butted light and covered with stretched cloths.

DESCRIPTION DETAILLEE DES FIGURESDETAILED DESCRIPTION OF THE FIGURES

Les lisses illustrées sur les figures 1 à 4 sont destinées à former des profilés pour structures tridimensionnelles, notamment ornementales, sur lesquels des toiles tendues sont placées.The rails illustrated on the Figures 1 to 4 are intended to form profiles for three-dimensional structures, in particular ornamental, on which stretched cloths are placed.

La figure 1 illustre un premier mode de réalisation d'une lisse lumineuse de section transversale sensiblement circulaire (1).The figure 1 illustrates a first embodiment of a light beam of substantially circular cross section (1).

La figure 2 illustre une lisse lumineuse de ce premier mode de réalisation de section transversale sensiblement circulaire (1) sur laquelle deux toiles tendues (2, 3) sont accrochées.The figure 2 illustrates a light rail of this first embodiment of substantially circular cross-section (1) on which two stretched canvases (2, 3) are hung.

La lisse lumineuse (1) de ce premier mode de réalisation est de section transversale sensiblement circulaire. La lisse (1) comprend deux évidements contigus (4, 5) de même dimension séparés par une langue (6). Ces évidements ont la même profondeur et la même largeur. Ils comportent respectivement un fond, une paroi latérale interne constituant une face de la langue (6) et une paroi latérale externe.The light rail (1) of this first embodiment is of substantially circular cross section. The arm (1) comprises two contiguous recesses (4, 5) of the same size separated by a tongue (6). These recesses have the same depth and the same width. They comprise respectively a bottom, an inner side wall constituting a face of the tongue (6) and an outer side wall.

Ces évidements (4, 5) sont symétriques latéralement par rapport à la langue (6). Les parois latérales externes des évidements (4, 5) comprennent des épaulements dirigés vers la cavité de l'évidement (7, 8). Ces épaulements (7, 8) sont disposés en vis-à-vis d'épaulements (9, 10) placés sur chaque face de la langue (6). Ces épaulements (7, 8, 9, 10) forment des butés pour retenir des éléments de fixation (11, 12) des toiles tendues (2, 3) sur la structure tridimensionnelle comme présenté en figure 2.These recesses (4, 5) are laterally symmetrical with respect to the tongue (6). The outer side walls of the recesses (4, 5) comprise shoulders directed towards the cavity of the recess (7, 8). These shoulders (7, 8) are arranged vis-à-vis shoulders (9, 10) placed on each side of the tongue (6). These shoulders (7, 8, 9, 10) form stops to retain fastening elements (11, 12) of the stretched cloths (2, 3) on the three-dimensional structure as shown in FIG. figure 2 .

La lisse étant construite selon une section transversale sensiblement circulaire, les parois latérales externes des évidements (4, 5) constituent des ailes périphériques (13, 14) pour la lisse dont la surface externe est courbe et suit un cercle de rayon sensiblement équivalent à la hauteur de la langue et par la même des évidements. La jonction (15) entre l'extrémité supérieure de la paroi latérale externe de l'évidemment et la surface externe de l'aile est arrondie pour ne pas abîmer la toile tendue fixée dans l'évidement. Une des ailes périphériques (13) s'étend sur ¾ de cercle d'un rayon équivalent à la profondeur des évidements (4). Cette aile (13) sert de support à une toile tendue (3) et permet de donner une forme arrondie à la toile tendue.The arm is constructed in a substantially circular cross section, the outer side walls of the recesses (4, 5) constitute peripheral wings (13, 14) for the arm whose outer surface is curved and follows a circle of radius substantially equivalent to the height of the tongue and by the same of the recesses. The junction (15) between the upper end of the outer lateral wall of the recess and the outer surface of the wing is rounded so as not to damage the stretched fabric fixed in the recess. One of the peripheral wings (13) extends over ¾ of a circle of a radius equivalent to the depth of the recesses (4). This wing (13) serves as a support for a stretched canvas (3) and allows to give a rounded shape to the stretched canvas.

La lisse tubulaire lumineuse (1) conformément à l'invention comporte une encoche (16) dans laquelle des diodes électroluminescentes sont intégrées. Cette encoche (16) est découpée dans l'aile périphérique (14) opposée à l'aile support (13) de la toile. L'encoche (16) forme un angle droit vers l'intérieur de la lisse. L'angle droit de l'encoche consiste préférentiellement en une petite arrête (16a) et une grande arrête (16b), la grande arrête (16b) étant parallèle aux parois des évidements (4, 5) et aux faces de la langues (6). La grande arrête (16b) est d'une hauteur sensiblement identique à la profondeur des évidements (4, 5). L'encoche accueille le système d'alimentation des diodes ainsi que les diodes électroluminescentes.The luminous tubular arm (1) according to the invention comprises a notch (16) in which light-emitting diodes are integrated. This notch (16) is cut in the peripheral flange (14) opposite the support flange (13) of the fabric. The notch (16) forms a right angle to the inside of the rail. The right angle of the notch is preferably a small stop (16a) and a large stop (16b), the large stop (16b) being parallel to the walls of the recesses (4, 5) and the faces of the tongue (6). ). The large stop (16b) is of a height substantially identical to the depth of the recesses (4, 5). The notch accommodates the power supply of the diodes as well as the light-emitting diodes.

La lisse comporte en outre une cavité (17) sous jacente aux évidements (4, 5), ladite cavité (17), dans l'exemple de réalisation présenté, étant parallélépipédique. Les lisses conformes à l'invention sont aboutées pour former un profilé en les enfilant par la cavité (17) sur un guide (non représenté) afin de constituer une partie de l'ossature de la structure tridimensionnelle.The beam further comprises a cavity (17) underlying the recesses (4, 5), said cavity (17), in the embodiment shown, being parallelepiped. The heddles according to the invention are abutted to form a profile by threading them through the cavity (17) on a guide (not shown) to form a part of the framework of the three-dimensional structure.

La figure 2 représente une lisse tubulaire conformément à l'invention sur laquelle deux toiles tendues (2, 3) sont accrochées. La première toile tendue (2) est accrochée à l'aide d'un crochet (12) dans un premier évidement (5) et constitue une face de la structure tridimensionnelle. La deuxième toile tendue (3) est accrochée à l'aide d'un crochet (11) dans un deuxième évidemment (4), adjacent au premier évidemment (5), et forme l'autre face de la structure tridimensionnelle. Cette toile tendue (3) est disposée autour de la lisse à environ 180° de sorte que les toiles tendues (2, 3) cachent entièrement la lisse (1). Les deux toiles tendues (2, 3) délimitent un espace entre elles dans lequel la lumière des diodes électroluminescentes intégrées dans l'encoche (13) de la lisse diffuse. L'exemple ci-dessus n'est pas limitatif et l'espace entre les toiles peut varier selon la structure tridimensionnelle finale. La seconde toile enveloppe donc plus ou moins la lisse.The figure 2 represents a tubular smooth according to the invention on which two stretched fabrics (2, 3) are hung. The first stretched canvas (2) is hooked (12) into a first recess (5) and forms a face of the three-dimensional structure. The second stretched canvas (3) is hooked with a hook (11) in a second obviously (4), adjacent to the first obviously (5), and forms the other side of the three-dimensional structure. This stretched fabric (3) is arranged around the rail at approximately 180 ° so that the stretched fabrics (2, 3) completely hide the rail (1). The two tensioned canvases (2, 3) delimit a space between them in which the light of the light-emitting diodes integrated in the notch (13) of the diffuse beam. The above example is not limiting and the space between the paintings can vary according to the final three-dimensional structure. The second canvas thus more or less envelopes the smooth.

La figure 3 présente un second mode de réalisation de l'invention. La lisse lumineuse (18) de ce second mode de réalisation est de section transversale sensiblement circulaire. La lisse (18) comprend deux évidements contigus (19, 20) de même dimension séparés par une langue (21), ces évidements ont la même profondeur et la même largeur. Ils comportent respectivement un fond (22), une paroi latérale interne (23) constituant une face de la langue et une paroi latérale externe (24). Ces évidements (19, 20) sont symétriques latéralement par rapport à la langue (21). Les parois latérales externes (24) des évidements (20) comprennent des épaulements dirigés vers la cavité de l'évidement (25). Ces épaulements (25) sont disposés en vis-à-vis d'épaulements (26) placés sur chaque face de la langue (21). Ces épaulements (25, 26) forment des butés pour retenir des éléments de fixation des toiles tendues sur la structure tridimensionnelle.The figure 3 presents a second embodiment of the invention. The light rail (18) of this second embodiment is of substantially circular cross section. The rail (18) comprises two contiguous recesses (19, 20) of the same size separated by a tongue (21), these recesses have the same depth and the same width. They comprise respectively a bottom (22), an inner side wall (23) constituting a face of the tongue and an outer side wall (24). These recesses (19, 20) are symmetrical laterally with respect to the tongue (21). The outer side walls (24) of the recesses (20) comprise shoulders directed towards the cavity of the recess (25). These shoulders (25) are arranged vis-à-vis shoulders (26) placed on each side of the tongue (21). These shoulders (25, 26) form stops to retain fasteners stretched fabrics on the three-dimensional structure.

La lisse (18) étant construite selon une section transversale sensiblement circulaire, les parois latérales externes des évidements (24) constituent des ailes périphériques (27, 28) pour la lisse dont la surface externe est courbe et suit un cercle de rayon sensiblement équivalent à la hauteur de la langue et par la même des évidements. La jonction (29) entre l'extrémité supérieure de la paroi latérale externe (24) de l'évidement et la surface externe de l'aile est arrondie pour ne pas abîmer la toile tendue fixée dans l'évidement. Dans ce second mode de réalisation, les ailes périphériques (27, 28) sont symétriques par rapport à la langue et définissent une encoche (30). L'encoche (30) comporte un fond (31) parallèle au fond (22) des évidements (19, 20) et deux parois latérales (32, 33). Le fond (31) de l'encoche (30) est en outre d'une largeur équivalente à la distance séparant les parois latérales externes entre les deux évidements (19, 20). Les parois latérales (33) de l'encoche (30) sont dans le même plan que les parois latérales externes (24) des évidements (20). Chaque aile s'étend donc en arc de cercle depuis la jonction (29) entre l'extrémité supérieure de la paroi latérale externe (24) de l'évidement jusqu'à l'extrémité inférieure de la paroi latérale (32, 33) de l'encoche.The arm (18) being constructed in a substantially circular cross-section, the outer side walls of the recesses (24) constitute peripheral wings (27, 28) for the arm whose outer surface is curved and follows a circle of radius substantially equivalent to the height of the tongue and by the same of the recesses. The junction (29) between the upper end of the outer side wall (24) of the recess and the outer surface of the wing is rounded so as not to damage the stretched fabric fixed in the recess. In this second embodiment, the peripheral wings (27, 28) are symmetrical with respect to the tongue and define a notch (30). The notch (30) has a bottom (31) parallel to the bottom (22) of the recesses (19, 20) and two side walls (32, 33). The bottom (31) of the notch (30) is furthermore of a width equivalent to the distance separating the external lateral walls between the two recesses (19, 20). The side walls (33) of the notch (30) are in the same plane as the outer side walls (24) of the recesses (20). Each wing therefore extends in an arc from the junction (29) between the upper end of the outer side wall (24) of the recess to the lower end of the side wall (32, 33). the notch.

L'encoche (30) est destinée à accueillir la source lumineuse de type diodes électroluminescentes avec leur système d'alimentation. L'encoche (30) est également apte à coopérer avec l'ossature de la structure tridimensionnelle. La lisse comporte également des moyens de fixation de la lisse à l'ossature de la structure tridimensionnelle.The notch (30) is intended to accommodate the light source type LEDs with their power supply system. The notch (30) is also able to cooperate with the framework of the three-dimensional structure. The rail also comprises means for fixing the rail to the framework of the three-dimensional structure.

La figure 4 présente un troisième mode de réalisation d'une lisse lumineuse selon l'invention.The figure 4 presents a third embodiment of a light rail according to the invention.

De même que les lisses des modes de réalisation précédemment décrits, la lisse lumineuse (40) de ce troisième mode de réalisation présente une section transversale sensiblement circulaire et comprend deux évidements contigus (41, 42), avantageusement de même dimension, séparés par une langue (43). Les évidements (41, 42), de même profondeur et de même largeur, comportent respectivement un fond (44), une paroi latérale interne (45) constituant une face de la langue et une paroi latérale externe (46). Les évidements (41, 42) sont symétriques latéralement par rapport à la langue (43). Les parois latérales externes (46) des évidements (41, 42) comprennent des épaulements (47) dirigés vers l'intérieur de l'évidement associé. Ces épaulements (47) sont disposés en vis-à-vis d'épaulements (48) placés sur chaque face de la langue (43). Ces épaulements (47, 48) forment des butés pour retenir des éléments de fixation des toiles tendues sur la structure tridimensionnelle.As well as the smooth of the embodiments described above, the light rail (40) of this third embodiment has a substantially circular cross section and comprises two contiguous recesses (41, 42), advantageously of the same size, separated by a tongue (43). The recesses (41, 42), likewise depth and the same width respectively comprise a bottom (44), an inner side wall (45) constituting a face of the tongue and an outer side wall (46). The recesses (41, 42) are laterally symmetrical with respect to the tongue (43). The outer side walls (46) of the recesses (41, 42) include shoulders (47) directed inwardly of the associated recess. These shoulders (47) are arranged vis-à-vis shoulders (48) placed on each side of the tongue (43). These shoulders (47, 48) form abutments for retaining fasteners stretched fabrics on the three-dimensional structure.

La lisse (40) étant construite selon une section transversale sensiblement circulaire, les parois latérales externes des évidements (41, 42) constituent des ailes périphériques (49, 50) pour la lisse dont la surface périphérique (surface externe) est courbe. La jonction entre l'extrémité supérieure de la paroi latérale externe de l'évidement et la surface externe de l'aile est arrondie pour ne pas abîmer la toile tendue fixée dans l'évidement.The arm (40) is constructed in a substantially circular cross section, the outer side walls of the recesses (41, 42) constitute peripheral wings (49, 50) for the smooth whose peripheral surface (outer surface) is curved. The junction between the upper end of the outer side wall of the recess and the outer surface of the wing is rounded so as not to damage the stretched fabric fixed in the recess.

Dans ce mode de réalisation, la lisse (40) comporte, sur sa surface périphérique, trois encoches (51, 52, 53), avantageusement droites, aptes à recevoir des diodes électroluminescentes et un système d'alimentation associé.In this embodiment, the arm (40) comprises, on its peripheral surface, three notches (51, 52, 53), preferably straight, adapted to receive light emitting diodes and an associated power system.

Plus particulièrement, l'une des encoches (51) est située diamétralement opposée aux évidements (41, 42). Cette encoche (51), similaire à l'encoche (30) de la lisse (18) du deuxième mode de réalisation illustrée sur la figure 3, comporte un fond (510) parallèle au fond (44) des évidements (41, 42) et deux parois latérales (511, 512). Avantageusement, le fond (510) de l'encoche (51) présente une largeur sensiblement égale à la distance entre les parois latérales externes (46) des deux évidements (41, 42) tandis que les parois latérales (511, 512) de l'encoche (51) s'étendent dans le même plan que les parois latérales externes (46) des évidements (41, 42).More particularly, one of the notches (51) is located diametrically opposite the recesses (41, 42). This notch (51), similar to the notch (30) of the arm (18) of the second embodiment illustrated on the figure 3 , has a bottom (510) parallel to the bottom (44) of the recesses (41, 42) and two side walls (511, 512). Advantageously, the bottom (510) of the notch (51) has a width substantially equal to the distance between the outer side walls (46) of the two recesses (41, 42) while the side walls (511, 512) of the notch (51) extend in the same plane as the outer side walls (46) of the recesses (41, 42).

Les deux autres encoches (52, 53) sont situées de part et d'autre de l'encoche (51). Avantageusement, les encoches (52, 53) sont situées à équidistance de l'encoche (51) et disposées diamétralement opposées l'une de l'autre. Elles présentent ainsi des ouvertures opposées l'une de l'autre, s'étendant respectivement dans des plans sensiblement perpendiculaires avec celui dans lequel s'étend l'ouverture de l'encoche (51). Les encochesThe other two notches (52, 53) are located on either side of the notch (51). Advantageously, the notches (52, 53) are located equidistant from the notch (51) and arranged diametrically opposite one another. They thus have opposite openings from each other, extending respectively in planes substantially perpendicular to that in which extends the opening of the notch (51). The notches

(52, 53) comportent respectivement un fond (520, 530) et deux parois latérales (521, 522, 531, 532) parallèles avec le fond (51) de l'encoche (51). Les fonds de chacune des encoches (52, 53) s'étendent parallèles entre eux et perpendiculairement au fond (510) de l'encoche (51).(52, 53) respectively comprise a bottom (520, 530) and two side walls (521, 522, 531, 532) parallel to the bottom (51) of the notch (51). The bottoms of each of the notches (52, 53) extend parallel to each other and perpendicularly to the bottom (510) of the notch (51).

Avantageusement, la lisse (40) comporte une cavité (54) longitudinale, de section sensiblement rectangulaire, interposée entre les évidements (41, 42) et l'encoche (51) placée à l'opposé des évidements. La cavité (54) s'étend sur toute la longueur de la lisse (40). La cavité (54) a la même fonction que la cavité (17) de la lisse (1) du premier mode de réalisation.Advantageously, the arm (40) has a cavity (54) longitudinal, of substantially rectangular section, interposed between the recesses (41, 42) and the notch (51) placed opposite the recesses. The cavity (54) extends along the entire length of the rail (40). The cavity (54) has the same function as the cavity (17) of the arm (1) of the first embodiment.

L'invention porte également sur une structure tridimensionnelle lumineuse comportant au moins un profilé constitué de lisses conformément à l'invention, lesdites lisses étant aboutées. Des toiles tendues sont accrochées aux lisses aboutées en profilés pour constituer la structure tridimensionnelle lumineuse en toiles tendues. Cette structure tridimensionnelle peut être un faux plafond, une fausse paroi, un luminaire, une forme de fantaisie, un élément de décoration ou tout autre objet éclairé tridimensionnel.The invention also relates to a three-dimensional luminous structure comprising at least one section consisting of heddles according to the invention, said heddles being butted. Stretched canvases are attached to the smooth butted sections to form the three-dimensional structure in bright canvas stretched. This three-dimensional structure can be a false ceiling, a false wall, a luminaire, a form of fantasy, a decorative element or any other three-dimensional illuminated object.

Il est bien entendu que l'invention ne se limite pas aux exemples de réalisation présentés ci-dessus.It is understood that the invention is not limited to the embodiments described above.
