Description

DOMAINE TECHNIQUE DE L'INVENTION.TECHNICAL FIELD OF THE INVENTION

L'invention concerne le domaine des toiles tendues.The invention relates to the field of stretched fabrics.

L'invention concerne plus particulièrement une lisse double pour la réalisation d'une structure en toiles tendues.The invention relates more particularly to a double rail for the production of a stretched canvas structure.

L'invention est destinée notamment, mais non exclusivement, à la réalisation de structure tridimensionnelle à toiles tendues.The invention is intended in particular, but not exclusively, for producing a three-dimensional structure with stretched cloths.

ETAT DE LA TECHNIQUESTATE OF THE ART

De manière classique en soi, une lisse double est un élément séparateur permettant d'assurer de part et d'autre le maintien de toiles tendues. Ce type de lisse est utilisé pour la réalisation de fausses parois (faux plafond et fausses parois murales) mais également pour la réalisation de structures tridimensionnelles. Elles permettent ainsi l'obtention de formes diverses, formes d'autant plus variées lorsque la configuration de telles lisses autorise leur cintrage.In a conventional manner, a double rail is a separating element to ensure the maintenance of stretched fabrics on both sides. This type of rail is used for the production of false walls (false ceiling and false walls) but also for the realization of three-dimensional structures. They thus make it possible to obtain various shapes, forms that are all the more varied when the configuration of such rails allows them to be bent.

Par exemple, le document EP 2610541 A décrit un agencement d'éclairage de plafond. Celui-ci comprend au moins un canal et au moins un élément d'éclairage de zone qui est fixé à au moins un côté du canal et au moins une surface de diffusion. Le canal comprend un boîtier en forme de U avec un fond ouvert à éclairer.For example, the document EP 2610541A describes a ceiling lighting arrangement. This includes at least one channel and at least one zone lighting element which is attached to at least one side of the channel and at least one diffusion surface. The channel comprises a U-shaped housing with an open bottom to illuminate.

Une lisse double, même lorsqu'elle concerne une lisse dite invisible, a cependant pour inconvénient de présenter un espace entre les toiles adjacentes lorsque ces dernières sont montées sur la lisse. L'espace rendu visible par l'ombre créé confère à la structure réalisée un aspect inesthétique.A double rail, even when it relates to a so-called invisible rail, however has the disadvantage of having a space between the adjacent webs when they are mounted on the rail. The space made visible by the created shadow confers on the realized structure an unsightly appearance.

Afin de tenter de pallier cet inconvénient, il est connu d'obturer cet espace au moyen d'un cache de finition rapporté. Un tel cache ne compense cependant pas totalement le défaut d'esthétique de la lisse rn question, ce dernier restant en effet malgré tout visible.In an attempt to overcome this disadvantage, it is known to seal this space by means of a reported finishing cover. However, such a cache does not completely compensate for the lack of aesthetics of the smooth question, the latter remains indeed despite everything visible.

L'invention vise à remédier aux problèmes des lisses doubles de l'art antérieur en proposant une lisse double offrant une projection d'ombre limitée et autorisant des opérations de cintrage pour la réalisation de structures tridimensionnelles de toutes formes.The invention aims to remedy the problems of double rails of the prior art by providing a double rail with a limited shadow projection and allowing bending operations for the realization of three-dimensional structures of all shapes.

L'invention a également pour objet de proposer une lisse lumineuse offrant un éclairage sans éblouissement et limitant toute projection ou zone d'ombre.The object of the invention is also to propose a luminous rail providing glare-free lighting and limiting any projection or shadow area.

L'invention a également pour objet de proposer une lisse permettant un montage aisé des toiles tendues tout en offrant un aspect esthétique satisfaisant.Another object of the invention is to propose a rail allowing a easy assembly of stretched canvas while providing a satisfactory aesthetic appearance.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

A cet effet, et selon un premier aspect, l'invention propose une lisse double pour la réalisation d'une structure en toiles tendues selon la revendication 1, présentant un corps tubulaire comprenant une ouverture de passage longitudinale pour le passage de toiles tendues. La lisse est remarquable en ce que le corps tubulaire comprend deux ailes internes convergeant l'une vers l'autre et délimitant, avec une paroi interne, une cavité dans laquelle des moyens lumineux sont logés, la cavité étant ouverte en direction de l'ouverture de passage.For this purpose, and according to a first aspect, the invention provides a double rail for the realization of a stretched canvas structure according to claim 1, having a tubular body comprising a longitudinal passage opening for the passage of stretched cloths. The arm is remarkable in that the tubular body comprises two inner wings converging towards one another and delimiting, with an inner wall, a cavity in which light means are housed, the cavity being open towards the opening of passage.

Ainsi, de par cette configuration, la lisse double selon l'invention permet de limiter la projection d'ombre entre les deux toiles ou les portions de toile fixées de part et d'autre de la lisse et d'autre part d'autoriser des opérations de cintrage. Sur ce dernier point, cela permet ainsi de réaliser des structures, notamment en 3D, tout type de formes.Thus, by this configuration, the double rail according to the invention makes it possible to limit the projection of shadow between the two canvases or the portions of fabric fixed on either side of the rail and, on the other hand, to allow bending operations. On this last point, it allows to realize structures, especially in 3D, any type of forms.

Avantageusement, les ailes internes sont dimensionnées pour définir une largeur d'ouverture égale ou inférieure à celle de l'ouverture de passage du corps tubulaire.Advantageously, the inner wings are dimensioned to define an opening width equal to or less than that of the passage opening of the tubular body.

Avantageusement, chaque aile interne converge vers la portion de paroi périphérique adjacente.Advantageously, each inner wing converges towards the adjacent peripheral wall portion.

Selon l'invention, chaque aile interne est arrangée pour former respectivement un support d'accrochage d'une toile tendue.According to the invention, each inner wing is arranged to form respectively a hooking support of a stretched canvas.

Avantageusement, chaque aile interne est agencée avec la paroi périphérique du corps pour délimiter une gorge de réception d'une toile tendue, chaque aile interne comprenant un épaulement permettant l'accroche de la bordure en forme de harpon de la toile tendue, l'épaulement s'étendant en direction de la paroi périphérique correspondante.Advantageously, each inner wing is arranged with the peripheral wall of the body to delimit a receiving groove of a stretched fabric, each inner wing comprising a shoulder allowing the hooking of the harpoon-like edge of the stretched fabric, the shoulder extending towards the corresponding peripheral wall.

Avantageusement, chaque aile interne présente une extrémité libre pourvue d'un rebord s'étendant en direction de la cavité.Advantageously, each inner wing has a free end provided with a flange extending towards the cavity.

Avantageusement, l'ouverture de passage est obturée par un cache de diffusion longitudinal amovible. Cela permet ainsi d'augmenter la diffusion et l'homogénéité de la lumière.Advantageously, the passage opening is closed by a removable longitudinal diffusion cover. This makes it possible to increase the diffusion and the homogeneity of the light.

Avantageusement, le cache de diffusion est clipsé au niveau du rebord de chaque aile interne.Advantageously, the diffusion cover is clipped at the edge of each inner wing.

Avantageusement, la lisse double présente un corps tubulaire de section transversale circulaire.Advantageously, the double smooth has a tubular section body circular cross.

Avantageusement, la lisse double présente au moins une portion cintrée.Advantageously, the double stringer has at least one curved portion.

L'invention concerne également une structure tridimensionnelle comportant au moins une lisse double telle que décrite précédemment, sur laquelle au moins une toile tendue est fixée.The invention also relates to a three-dimensional structure comprising at least one double rail as described above, on which at least one stretched fabric is fixed.

DESCRIPTION DETAILLEE DES FIGURESDETAILED DESCRIPTION OF THE FIGURES

En relation avec les figures 1 et 2, il est décrit une lisse double 1 lumineuse permettant la réalisation d'une structure tridimensionnelle en toiles tendues.In relation to Figures 1 and 2 , it is described a double 1 luminous smooth for the realization of a three-dimensional structure stretched canvas.

Dans le mode de réalisation illustré, la lisse double 1 présente un corps cylindrique 2 creux comprenant une ouverture de passage 3 longitudinale pour le passage de deux bordures au plus d'une même toile ou de deux toiles distinctes, les bordures étant pourvues de moyens d'accroche, avantageusement en forme de harpon. Avantageusement, l'ouverture de passage 3 s'étend sur toute la longueur dudit corps 2.In the illustrated embodiment, the double rail 1 has a hollow cylindrical body 2 comprising a longitudinal passage opening 3 for the passage of two edges at most of the same fabric or two separate webs, the borders being provided with 'hangs, advantageously shaped harpoon. Advantageously, the passage opening 3 extends over the entire length of said body 2.

Le corps cylindrique 2 comprend deux ailes internes 4, 5 convergeant l'une vers l'autre et reliées à la paroi périphérique 20 par l'intermédiaire d'une paroi interne 6. Les ailes internes 4, 5 délimitent, avec la paroi interne 6, une cavité 7 ouverte en direction de l'ouverture de passage 3. Comme illustré sur les figures, la cavité 7 est destinée à loger des moyens lumineux 18 comme par exemple des LEDs. Dans le mode de réalisation illustré, la cavité 7 comporte des moyens lumineux portés par chacune des ailes internes 4, 5 ainsi que par la paroi interne 6. Il est bien entendu évident que l'invention ne se limite pas à cette configuration est qu'il peut prévu que les moyens lumineux 18 ne soient ménagés que sur l'une des ailes et/ou de la paroi interne 6.The cylindrical body 2 comprises two inner flanges 4, 5 converging towards each other and connected to the peripheral wall 20 via an inner wall 6. The inner flanges 4, 5 delimit, with the inner wall 6 , a cavity 7 open towards the passage opening 3. As illustrated in the figures, the cavity 7 is intended to house light means 18 such as LEDs. In the illustrated embodiment, the cavity 7 comprises light means carried by each of the inner wings 4, 5 and the inner wall 6. It is of course obvious that the invention is not limited to this configuration is that it can be provided that the light means 18 are formed only on one of the wings and / or the inner wall 6.

Avantageusement, les ailes internes 4, 5 sont dimensionnées pour définir une largeur d'ouverture légèrement inférieure à celle de l'ouverture de passage 3 du corps cylindrique 2. L'avantage de cette configuration est qu'elle permet d'améliorer la retenu d'un cache de diffusion lorsqu'un tel cache est prévu tout en permettant d'assurer une projection d'ombre limitée.Advantageously, the inner wings 4, 5 are dimensioned to define an opening width slightly smaller than that of the passage opening 3 of the cylindrical body 2. The advantage of this configuration is that it makes it possible to improve the retention of a broadcast cache when such a cache is provided while allowing a limited shadow projection.

Dans le mode de réalisation illustré, chaque aile interne 4, 5 présente une extrémité libre pourvue d'un rebord 8 s'étendant en direction de la cavité 7, avantageusement, perpendiculaire à l'aile associée. Comme on le verra plus loin, les rebords 8 de chacune des ailes internes 4, 5 sont arrangés pour constituer des moyens d'accroche d'un cache de diffusion.In the illustrated embodiment, each inner wing 4, 5 has a free end provided with a flange 8 extending towards the cavity 7, preferably perpendicular to the associated wing. As will be seen below, the flanges 8 of each of the inner flanges 4, 5 are arranged to form means for attaching a diffusion cover.

Chaque aile interne est en outre agencée avec la paroi périphérique du corps cylindrique 2 pour délimiter une gorge de réception 9 d'une toile tendue. Afin d'assurer l'accroche de la toile dans la gorge de réception 9, chaque aile interne comprend un épaulement 10, sur la face opposée à celle délimitant la cavité 7, s'étendant en direction de la paroi périphérique. Chaque épaulement 10 est arrangé pour permettre l'accroche des bordures en forme de harpon des toiles tendues. Dans le mode de réalisation illustré, l'épaulement 10 est porté au niveau de l'extrémité libre de l'aile interne associé. Plus particulièrement, il est ménagé dans le prolongement du rebord 8 de l'aile, dans la direction opposée à ce dernier.Each inner wing is further arranged with the peripheral wall of the cylindrical body 2 to define a receiving groove 9 of a stretched fabric. To ensure the attachment of the fabric in the receiving groove 9, each inner wing comprises a shoulder 10, on the opposite side to that defining the cavity 7, extending towards the peripheral wall. Each shoulder 10 is arranged to allow the hooking of the harpoon edges of the stretched cloths. In the illustrated embodiment, the shoulder 10 is carried at the free end of the associated inner wing. More particularly, it is formed in the extension of the rim 8 of the wing, in the opposite direction to the latter.

Dans le mode de réalisation illustrée, la paroi interne 6 s'étend au travers du corps cylindrique 2, de part en part de la paroi périphérique 20, de sorte à délimiter de dernier en deux parties de dimension sensiblement également. Elle forme ainsi une paroi centrale. La paroi interne 6 est disposée à l'intérieur du corps 2 de manière à faire face à l'ouverture de passage 3.In the illustrated embodiment, the inner wall 6 extends through the cylindrical body 2, from one side of the peripheral wall 20, so as to delimit last in two parts of dimension substantially also. It thus forms a central wall. The inner wall 6 is disposed inside the body 2 so as to face the passage opening 3.

Avantageusement, la paroi interne 6 est pourvue, en partie haute (en relation avec la position de la lisse sur les figures), d'un rail 17 destiné à recevoir des moyens d'assemblage de la lisse avec une autre lisse. Afin de renforcer la résistance de la lisse, il est prévu deux entretoises 19 reliant le rail 17 à la paroi périphérique 20.Advantageously, the inner wall 6 is provided, in the upper part (in relation to the position of the rail in the figures), a rail 17 for receiving means for assembling the rail with another rail. In order to reinforce the resistance of the beam, two spacers 19 are provided which connect the rail 17 to the peripheral wall 20.

Selon une configuration particulière, illustrée sur les figures, la lisse double 1 comprend un cache de diffusion 11 longitudinal amovible apte à obturer en tout ou partie l'ouverture de passage 3. L'obturation de l'ouverture de passage 3 par l'intermédiaire d'un cache de diffusion 11 translucide permet d'augmenter la diffusion et l'homogénéité de la lumière. Avantageusement, le cache de diffusion 11 est translucide.According to a particular configuration, illustrated in the figures, the double rail 1 comprises a detachable longitudinal diffusion cover 11 capable of sealing in whole or in part the passage opening 3. The closing of the passage opening 3 by means of a translucent diffusion cover 11 makes it possible to increase the diffusion and the homogeneity of the light. Advantageously, the diffusion cache 11 is translucent.

Dans le mode de réalisation illustré, le cache de diffusion 11 comporte un corps tubulaire de section transversale rectangulaire. Plus particulièrement, le cache de diffusion 11 comprend deux parois d'obturation 12, 14 s'étendant en vis-à-vis l'une de l'autre et reliées entre elles par deux parois latérales 13, 15. Le cache de diffusion 11 comporte en outre deux pattes d'accroche 16 s'étendant dans le prolongement de la paroi latérale 13, 15 associée, dans une direction opposée aux parois d'obturation 12, 14. Comme on le comprend d'après les figures, les pattes d'accroche 16 sont destinées à coopérer avec les rebords 8 des ailes internes 4, 5.In the illustrated embodiment, the diffusion cover 11 comprises a tubular body of rectangular cross section. More particularly, the diffusion cover 11 comprises two closing walls 12, 14 extending opposite each other and interconnected by two side walls 13, 15. The diffusion cover 11 further comprises two gripping lugs 16 extending in the extension of the associated side wall 13, 15, in a direction opposite to the closing walls 12, 14. As can be understood from the figures, the lugs 16 16 are intended to cooperate with the flanges 8 of the inner wings 4, 5.

La paroi d'obturation 12 portant les pattes d'accroche 16 constitue une paroi de renfort permettant d'assurer le maintien des pattes d'accroche 16 du cache de diffusion 11 sur les rebords 8 des ailes internes 4, 5. La paroi d'obturation 14 la plus éloignée des pattes d'accroche 16 présente avantageusement une forme bombée de manière ce que, lorsque le cache de diffusion 11 est monté sur la lisse double 1, la lisse double 1 présente un corps tubulaire sans démarcation.The closure wall 12 carrying the fastening tabs 16 constitutes a reinforcing wall making it possible to maintain the fastening tabs 16 of the diffusion cover 11 on the flanges 8 of the inner flanges 4, 5. The wall of FIG. Closure 14 furthest away from the attachment tabs 16 advantageously has a convex shape so that, when the diffusion cover 11 is mounted on the double rail 1, the double rail 1 has a tubular body without demarcation.

On comprend bien que le cache de diffusion 11 présentera une forme et des dimensions complémentaires à celles de l'ouverture de passage 3 de sorte à permettre son insertion dans l'ouverture de passage 3. En outre, il sera avantageux de prévoir un dimensionnement du cache de diffusion 11 de manière à ce qu'il présente une face externe affleurant avec la face externe du corps cylindrique 2 de lisse double 1, comme illustré sur la figure 2.It is understood that the diffusion cover 11 will have a shape and dimensions complementary to those of the passage opening 3 so as to allow its insertion into the passage opening 3. In addition, it will be advantageous to provide a dimensioning of the diffusion cover 11 so that it has an outer face flush with the outer face of the cylindrical body 2 of double rail 1, as shown in FIG. figure 2 .

Outre sa fonction de diffusion de la lumière, le cache de diffusion 11 permet également d'améliorer le maintien de la toile sur la lisse double 1. En effet, et comme illustré, sur la figure 3, les toiles 30, 31 se trouvent en partie pincées entre le cache de diffusion 11 et les bords de la paroi périphérique 20 délimitant l'ouverture de passage 3.In addition to its light diffusion function, the diffusion cover 11 also makes it possible to improve the maintenance of the fabric on the double rail 1. Indeed, and as illustrated, on the figure 3 , the fabrics 30, 31 are partially pinched between the diffusion cover 11 and the edges of the peripheral wall 20 defining the passage opening 3.

Dans le mode de réalisation précédemment décrit, la lisse double 1 présente une section transversale en forme de C (ou circulaire étant entendu qu'une ouverture est ménagée). Il est bien entendu évident que la lisse selon l'invention ne se limite pas à cette forme et qu'il peut être prévu d'autres formes de sections sans sortir du cadre de l'invention.In the embodiment previously described, the double rail 1 has a C-shaped cross section (or circular being understood that an opening is formed). It is of course obvious that the rail according to the invention is not limited to this form and that other shapes of sections can be provided without departing from the scope of the invention.

L'invention est décrite dans ce qui précède à titre d'exemple. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de réalisation de l'invention sans pour autant sortir du cadre de l'invention.The invention is described in the foregoing by way of example. He is heard that the skilled person is able to achieve different embodiments of the invention without departing from the scope of the invention.
