Description

La présente invention concerne la conception et la réalisation de dispositifs d'affichage, tels que des panneaux publicitaires ou des panneaux d'information.The present invention relates to the design and production of display devices, such as panels advertising or information boards.

Ils sont essentiellement constitués par un panneau souple rectangulaire qui porte une information ou un message. Deux bords opposés de ce panneau souple, généralement les deux bords horizontaux, sont fixés sur une poutre dont chacune des extrémités est solidaire d'un chariot qui est guidé dans un rail perpendiculaire aux poutres. Les deux poutres sont maintenues écartées l'une par rapport à l'autre de manière à réaliser une forte tension du panneau souple dans une direction perpendiculaire aux poutres.They are essentially constituted by a flexible panel rectangular which carries information or a message. Two edges opposite of this flexible panel, usually the two edges horizontal, are fixed on a beam of which each of the ends is attached to a carriage which is guided in a perpendicular rail to the beams. The two beams are kept apart one by relative to each other so as to achieve a high tension of the panel flexible in a direction perpendicular to the beams.

On réalise ainsi une forte tension du panneau souple dans une seule direction, généralement la direction verticale et du fait de la valeur élevée de la tension exercée sur les deux bords horizontaux, il se crée une déformation des bords verticaux, qui présentent une déformation en forme de barillet avec des concavités dirigées vers l'intérieur du panneau, ce qui est préjudiciable à la bonne visibilité du message ou de l'information portée par le panneau.This produces a high tension of the flexible panel in only one direction, usually the vertical direction and due to the high value of the tension exerted on the two edges horizontal, a deformation of the vertical edges is created, which have a barrel-shaped deformation with concavities directed towards the inside of the panel, which is detrimental to the good visibility of the message or information carried by the sign.

En ce qui concerne les panneaux publicitaires, il est important qu'ils puissent être facilement et rapidement changés. Il faut donc concevoir des dispositifs d'affichage présentant une interchangeabilité rapide des panneaux.With regard to billboards, it is important that they can be easily and quickly changed. he must therefore design display devices with a rapid interchangeability of panels.

En particulier, il n'est pas possible actuellement de réaliser des panneaux présentant un profil non linéaire, par exemple des panneaux présentant un profil galbé ou angulaire qui soient facilement et rapidement interchangeables.In particular, it is not currently possible to carry out panels with a non-linear profile, for example panels with a curved or angular profile which are easily and quickly interchangeable.

La présente invention se propose donc de réaliser un dispositif d'affichage du type décrit ci-dessus qui ne présente pas de déformations latérales et, par conséquent, qui présente une bonne lisibilité, tout en présentant une structure simple qui permet un montage rapide des panneaux et, par conséquent, qui permet de changer rapidement le panneau affiché, ce qui est particulièrement important dans le cas de panneaux publicitaires.The present invention therefore proposes to produce a display device of the type described above which does not have lateral deformations and, therefore, which has a good readability, while presenting a simple structure which allows rapid assembly of the panels and, therefore, which allows quickly change the displayed panel, which is particularly important in the case of billboards.

A cet effet, l'invention a pour objet un dispositif d'affichage constitué par un panneau souple rectangulaire dont deux bords opposés sont fixés sur une poutre dont chacune des extrémités est solidaire d'un chariot qui est guidé dans un rail perpendiculaire aux poutres, les deux poutres étant maintenues écartées parallèlement l'une par rapport à l'autre de manière à réaliser une forte tension du panneau souple dans une direction perpendiculaire aux poutres, caractérisé en ce que chaque bord du panneau souple parallèle aux rails est monté à coulissement dans le rail correspondant.To this end, the invention relates to a display device consisting of a flexible rectangular panel with two edges opposite are fixed on a beam each end of which is secured to a carriage which is guided in a rail perpendicular to the beams, the two beams being kept apart parallel relative to each other so as to achieve a high tension of the flexible panel in a direction perpendicular to the beams, characterized in that each edge of the flexible panel parallel to the rails are slidably mounted in the corresponding rail.

De cette manière, on obtient, par une seule action mécanique, à savoir le tirage vertical du panneau, une tension de ce dernier, à la fois dans le sens du tirage et dans le sens perpendiculaire, ce qui élimine les distorsions du panneau dont les informations ou les messages sont toujours très lisibles. Selon un mode de réalisation, les bords du panneau souple comportent des éléments en forme de taquet qui s'engagent dans des glissières du rail correspondant.In this way, we obtain, by a single action mechanical, namely the vertical draw of the panel, a tension of this last, both in the direction of the draw and in the direction perpendicular, which eliminates the distortions of the panel whose information or messages are always very readable. According to a embodiment, the edges of the flexible panel include cleat-shaped elements which engage in slides of the corresponding rail.

De cette manière on obtient un guidage continu des bords latéraux du panneau souple sur toute leur longueur.In this way, continuous guidance of the edges is obtained. sides of the flexible panel over their entire length.

Pour la mise en place d'un panneau, il suffit d'engager les éléments en forme de taquet dans les glissières avant de procéder à la mise sous tension verticale du panneau souple. Cette structure simple permet de mettre en place et de tendre un panneau souple de manière rapide. En particulier, le remplacement d'un panneau par un autre est réalisé très rapidement, ce qui est important en particulier pour les panneaux publicitaires, pour lesquels la période d'affichage est relativement courte et qui doivent être remplacés souvent.For the installation of a panel, simply engage the cleat-like elements in the runners before proceeding vertical tensioning of the flexible panel. This structure simple allows to set up and stretch a flexible panel of quick way. In particular, replacing a panel with a other is done very quickly, which is particularly important for billboards, for which the display period is relatively short and should be replaced often.

Selon une autre caractéristique de l'invention, chaque bord du panneau souple fixé sur une poutre est tendu sur celle-ci de manière à obtenir une tension dans la direction parallèle aux poutres. According to another characteristic of the invention, each edge flexible panel attached to a beam is stretched over it so as to obtain a tension in the direction parallel to beams.

Grâce à cette disposition, on peut réaliser des panneaux d'affichage dont la tension est toujours réalisée sans déformation et qui présentent un profil non linéaire, par exemple courbe ou angulaire. Dans ce cas, les deux poutres présentent le profil désiré qui est maintenu sur toute la longueur du panneau souple.Thanks to this arrangement, panels can be produced display whose tension is always carried out without deformation and which have a non-linear profile, for example curved or angular. In this case, the two beams have the desired profile which is maintained over the entire length of the flexible panel.

Selon un mode de réalisation de l'invention, les bords du panneau fixés sur la poutre comportent un jonc qui est enfilé dans un logement correspondant de la poutre. Ce jonc, qui dépasse un peu du panneau souple est fixé dans le logement correspondant de la poutre, ce qui assure une fixation continue et efficace du bord du panneau souple sur la poutre.According to one embodiment of the invention, the edges of the panel fixed on the beam have a rod which is threaded in a corresponding housing of the beam. This rod, which exceeds a little of the flexible panel is fixed in the corresponding housing of the beam, which ensures a continuous and effective fixing of the edge of the flexible panel on the beam.

Selon une autre caractéristique de l'invention, les bords du panneau souple parallèles aux poutres comportent une bande de serrage qui déborde des deux côtés du panneau souple et qui est fixée à ses deux extrémités derrière le panneau souple sur la poutre.According to another characteristic of the invention, the edges of the flexible panel parallel to the beams have a strip of clamping which extends beyond both sides of the flexible panel and which is fixed at both ends behind the flexible panel on the beam.

Avantageusement, une des extrémités de cette bande de serrage est fixée au moyen d'un dispositif à tension réglable tel qu'un tendeur à cliquet.Advantageously, one end of this strip of clamping is fixed by means of an adjustable tension device such than a ratchet tensioner.

De cette manière, on réalise la première tension de pré-positionnement du panneau souple sur chacune des poutres.In this way, the first pre-positioning voltage is produced flexible panel on each of the beams.

Selon une autre caractéristique de l'invention, les extrémités des poutres comportent des pièces de coin arrondies sur lesquelles le bord du panneau souple est appliqué.According to another characteristic of the invention, the ends of beams have rounded corner pieces on which the edge of the flexible panel is applied.

Ceci facilite la mise sous tension de pré-positionnement des bords du panneau souple.This facilitates pre-positioning power up edges of the flexible panel.

Selon encore une autre caractéristique de l'invention, le dispositif d'affichage comporte un écran opaque disposé derrière le panneau souple.According to yet another characteristic of the invention, the display device has an opaque screen disposed behind the flexible panel.

Avantageusement, une source lumineuse est fixée sur chacune des poutres de manière à rayonner dans la zone disposée entre l'arrière du panneau souple et l'écran opaque. Advantageously, a light source is fixed on each of the beams so as to radiate in the arranged area between the back of the flexible panel and the opaque screen.

L'écran rigide opaque est une protection supplémentaire du panneau souple ; par ailleurs, cette disposition permet de réaliser un panneau d'affichage avec éclairage par l'arrière.The rigid opaque screen is an additional protection of the flexible panel; moreover, this arrangement makes it possible to carry out a display panel with back lighting.

Avantageusement, l'écran opaque porte un message ou une information.Advantageously, the opaque screen carries a message or a information.

Ceci permet, en particulier dans le cas de panneaux publicitaires, d'avoir un panneau de fond comportant un message d'ordre général et devant lequel on peut placer un panneau comportant un message particulier qui doit être changé souvent.This allows, in particular in the case of panels advertising, to have a back panel with a message general and in front of which a panel can be placed with a particular message that needs to be changed often.

Selon une autre caractéristique de l'invention, une des poutres est fixe et l'autre est mobile, un câble de tension est fixé à chaque extrémité de la poutre mobile et est guidé par une poulie de renvoi montée sur l'extrémité voisine du rail correspondant et les autres extrémités libres des câbles de tension sont tirées en direction de la poutre fixe au moyen d'un dispositif tendeur fixé au voisinage de la poutre fixe.According to another characteristic of the invention, one of the beams is fixed and the other is mobile, a tension cable is fixed to each end of the mobile beam and is guided by a pulley of return mounted on the adjacent end of the corresponding rail and the other free ends of the tension cables are pulled in direction of the fixed beam by means of a tensioning device fixed to the vicinity of the fixed beam.

Avantageusement, les extrémités libres des tendeurs sont reliées à un câble entraíné par le dispositif tendeur.Advantageously, the free ends of the tensioners are connected to a cable driven by the tensioning device.

Ce dispositif est de structure simple et permet de réaliser facilement la tension verticale du panneau souple à partir de sa partie inférieure ce qui évite d'avoir à utiliser une échelle.This device is of simple structure and allows to realize easily the vertical tension of the flexible panel from its lower part which avoids having to use a ladder.

Avantageusement, les poutres et les rails sont constitués par des profilés métalliques, par exemple en aluminium. Ceci permet de diminuer notablement le poids et le prix du dispositif d'affichage.Advantageously, the beams and the rails are made up by metal profiles, for example aluminum. this allows to significantly reduce the weight and the price of the display device.

La figure 1 représente un dispositif d'affichage, par exemple un panneau publicitaire, qui comporte essentiellement un panneau souple rectangulaire 1 qui porte une inscription et qui est constitué par exemple par une feuille ou une toile en matière synthétique. Cette toile 1 est maintenue sur deux poutres horizontales, une poutre inférieure fixe 2 et une poutre supérieure mobile 3 et deux rails verticaux 4 et 5. La toile 1 déborde des deux côtés des poutres 2 et 3 et on prévoit à cet effet des éléments de coin 6 de forme arrondie en quart de cercle qui sont fixés sur les extrémités des poutres 2 et 3 et sur lesquels sont appliquées les extrémités des bords inférieurs et supérieurs de la toile 1.Figure 1 shows a display device, for example a billboard, which basically has a flexible rectangular panel 1 which bears an inscription and which is constituted for example by a sheet or a canvas of material synthetic. This canvas 1 is held on two beams horizontal, a fixed lower beam 2 and an upper beam mobile 3 and two vertical rails 4 and 5. The fabric 1 extends beyond both sides of beams 2 and 3 and for this purpose elements of corner 6 of rounded quarter circle shape which are fixed on the ends of beams 2 and 3 and to which the ends of the lower and upper edges of the fabric 1.

Un écran opaque 30 est fixé sur les rails 4 et 5 derrière le panneau souple 5.An opaque screen 30 is fixed on the rails 4 and 5 behind the flexible panel 5.

Comme on peut le voir sur la figure 2, les deux rails 4 et 5 sont disposés verticalement parallèlement l'un à l'autre et comportent un dispositif de guidage dans lequel circule un chariot 7 qui s'engage dans une poutre 2 ou 3, les extrémités de chaque poutre étant solidaires d'un chariot. Les éléments de coin 6 viennent se fixer sur l'extrémité des poutres 2 et 3. Les poutres 2 et 3 et les rails 4 et 5 sont constitués par des profilés métalliques, de préférence en aluminium qui sont représentés en détails sur les figures 3 et 4.As can be seen in Figure 2, the two rails 4 and 5 are arranged vertically parallel to each other and include a guide device in which a carriage 7 travels which engages in a beam 2 or 3, the ends of each beam being integral with a carriage. Corner elements 6 come attach to the end of beams 2 and 3. Beams 2 and 3 and rails 4 and 5 are made up of metal profiles, preferably aluminum which are shown in detail on the Figures 3 and 4.

La figure 3 représente en coupe le profilé constituant une des poutres, par exemple la poutre 2.Figure 3 shows in section the profile constituting a beams, for example beam 2.

La poutre présente sur sa face avant, c'est-à-dire sur la face gauche de la figure 3, un logement de forme circulaire 11 qui présente une ouverture correspondant sensiblement à l'épaisseur de la toile 1 et qui sert à recevoir un jonc 10 (voir figures 5 et 8).The beam present on its front face, that is to say on the left side of Figure 3, a circular shaped housing 11 which has an opening corresponding substantially to the thickness of the canvas 1 and which is used to receive a rod 10 (see FIGS. 5 and 8).

Le profilé 2 comporte également, au voisinage de sa face avant, un logement fermé 12 qui est destiné à recevoir l'élément de coin 6 et, sur sa face arrière, deux logements rectangulaires ouverts 13 destinés à recevoir chacun une patte du chariot 7.Profile 2 also has, in the vicinity of its face before, a closed housing 12 which is intended to receive the element of corner 6 and, on its rear side, two open rectangular housings 13 each intended to receive one leg of the carriage 7.

La figure 4 représente en coupe le profilé constituant un des rails, par exemple le rail 4. Il comporte sur sa face avant, c'est-à-dire sur sa face dirigée vers le bas sur la figure 4, un logement sensiblement carré 21 dans lequel on engage les roulettes du chariot 7 (voir figure 6). Sur sa face latérale extérieure, c'est-à-dire sur sa face dirigée vers la droite sur la figure 4, ce profilé 4 comporte un logement ouvert vers l'intérieur 22 qui constitue une glissière dans laquelle on fait glisser des éléments 23 en forme de T ou de taquets qui sont fixés sur le bord vertical de la toile 2 à intervalles réguliers. Le logement 14 disposé à la partie arrière intérieure du rail est destiné à recevoir l'écran opaque 30.Figure 4 shows in section the profile constituting a rails, for example rail 4. It has on its front face, that is to say on its face directed downwards in FIG. 4, a housing substantially square 21 in which the rollers of the carriage 7 (see Figure 6). On its external lateral face, i.e. on its face directed to the right in FIG. 4, this profile 4 has a housing open inwards 22 which constitutes a slide in which T-shaped elements 23 are dragged or cleats which are attached to the vertical edge of the fabric 2 to regular intervals. The housing 14 arranged at the rear part interior of the rail is intended to receive the opaque screen 30.

La figure 5 représente en perspective l'élément de coin 6. Sa forme générale est cylindrique avec une section en quart de cercle et il comporte une partie saillante 28 en forme de L qui vient s'engager dans le logement correspondant 11 des extrémités des poutres.

Pour faciliter l'insertion de la toile 1 dans l'élément de coin puis dans la poutre, ce jonc 10 déborde de chaque côté de la toile 1.FIG. 5 represents in perspective the corner element 6. Its general shape is cylindrical with a quarter section circle and it has an L-shaped protruding part 28 which comes engage in the corresponding housing 11 at the ends of the beams. On its part rounded in a quarter circle, this element of corner has a similar open circular shaped housing 26 to the housing 11 of the beam and into which the rod 10 engages arranged at each of the horizontal edges of the fabric 1. To facilitate the insertion of the canvas 1 in the corner element then in the beam, this rod 10 overflows on each side of the fabric 1.

A la suite du logement 26, l'élément de coin 6 présente, dans sa partie en forme de quart de cercle, une section de dimension plus faible 27 sur laquelle vient s'appliquer une bande de serrage 20 aménagée dans la toile 1 de manière adjacente au jonc 10. Cette bande de serrage 20 est crantée sur sa face intérieure et elle déborde largement de la toile 2 à ses deux extrémités. Elle sert à réaliser une tension horizontale de pré-positionnement comme expliqué sur la figure 9.Following the housing 26, the corner element 6 has, in its part in the shape of a quarter circle, a section of smaller dimension 27 on which a strip of clamping 20 arranged in the fabric 1 adjacent to the rod 10. This tightening band 20 is notched on its inner face and it extends well beyond the canvas 2 at its two ends. She serves to achieve a horizontal pre-positioning tension as explained in Figure 9.

La figure 6 représente le chariot 7. Il comporte un ensemble de cinq roulettes 31 et 32 qui sont disposées de manière alternée avec des axes de rotation perpendiculaires. Ce chariot 7 comporte également deux pattes de fixation 34 qui viennent s'engager et se fixer dans les logements 13 de la poutre 2 ou 3.Figure 6 shows the carriage 7. It has a set of five castors 31 and 32 which are arranged so alternated with perpendicular axes of rotation. This cart 7 also has two fixing lugs 34 which come engage and fix in the housings 13 of the beam 2 or 3.

La figure 7 représente, de manière schématique, l'arrière du dispositif d'affichage selon l'invention. On retrouve les deux poutres inférieures 2 et supérieures 3 et les rails 4 et 5 sur lesquels sont engagés les chariots 7. Cette figure représente en particulier le dispositif permettant d'obtenir la tension verticale du panneau souple 1. Ce dispositif comporte essentiellement deux câbles de tension 51 et 52 dont l'extrémité est fixée sur la poutre mobile supérieure 3. Chaque câble 51 et 52 passe sur une poulie de renvoi 53 qui est fixée sur le chariot supérieur du dispositif dans un logement 24 aménagé au voisinage de la glissière 22 comme représenté schématiquement sur la figure 4. Les deux extrémités libres des câbles de tension 51 et 52 sont raccordées à un câble unique 54 qui est entraíné par un dispositif tendeur 55, par exemple un treuil à cliquet. Les extrémités libres des câbles 51 et 52 sont assemblés sur l'extrémité du câble 54 par exemple au moyen d'une manille dans laquelle sont engagées des boucles aménagées aux extrémités des câbles 51, 52 et 54.Figure 7 shows, schematically, the rear of the display device according to the invention. We find the two lower 2 and upper 3 beams and rails 4 and 5 on which the carriages are engaged 7. This figure represents in particular the device for obtaining the vertical tension of the panel flexible 1. This device essentially comprises two cables of tension 51 and 52 whose end is fixed on the mobile beam upper 3. Each cable 51 and 52 passes over a deflection pulley 53 which is fixed on the upper carriage of the device in a housing 24 arranged in the vicinity of the slide 22 as shown schematically in Figure 4. The two ends free tension cables 51 and 52 are connected to a cable single 54 which is driven by a tensioning device 55, for example a ratchet winch. The free ends of cables 51 and 52 are assembled on the end of the cable 54 for example by means of a shackle in which loops fitted to the ends of cables 51, 52 and 54.

On voit sur la figure 8 l'ensemble des éléments assemblés, la poutre 2 étant représentée partiellement. On peut voir en particulier le chariot 7 avec ses roulettes 31 et 32 circulant dans le logement 21. We see in Figure 8 all the assembled elements, the beam 2 being partially represented. We can see in especially the carriage 7 with its casters 31 and 32 circulating in the housing 21.

La figure 9 est une vue schématique de dessus du dispositif d'affichage selon l'invention. On peut voir la poutre supérieure 3, les éléments de coin 6 et le panneau opaque 30. La toile 1 est appliquée sur la poutre 3 et les éléments 6 et elle est prolongée par la bande de serrage crantée 20. Une des extrémités de cette dernière est fixée sur la poutre 3 comme schématisé en 41 et son autre extrémité est engagée dans un dispositif tenseur 42, tel qu'un dispositif à cliquet, qui permet d'obtenir la tension désirée dans le sens horizontal sur chacune des extrémités horizontales de la toile 1.Figure 9 is a schematic top view of the display device according to the invention. We can see the beam upper 3, the corner elements 6 and the opaque panel 30. The canvas 1 is applied to the beam 3 and the elements 6 and it is extended by the notched clamping band 20. One of the ends of the latter is fixed to the beam 3 as shown schematically in 41 and its other end is engaged in a tensioning device 42, such a ratchet device, which allows to obtain the desired tension horizontally on each of the horizontal ends of canvas 1.

Le montage du dispositif d'affichage qui vient d'être décrit s'effectue de la manière suivante.The mounting of the display device which has just been described is carried out as follows.

Pour réaliser le support, on fixe les deux rails 4 et 5 sur deux poteaux-supports. Les chariots 7 sont fixés dans les extrémités des poutres 2 et 3, puis ces poutres sont mises en place dans les rails, la poutre supérieure mobile 3 étant engagée la première et poussée vers le haut. La poutre inférieure fixe 2 est fixée sur les rails et on fixe les extrémités des câbles de tension 51 et 52 sur la poutre supérieure mobile 3 en faisant passer ces câbles sur les poulies 53 et on termine l'assemblage du dispositif de serrage représenté sur la figure 7, le treuil 55 étant disposé en-dessous de la poutre fixe sur le support de manière à être facilement accessible.To make the support, the two rails 4 and 5 are fixed on two support posts. The carriages 7 are fixed in the ends beams 2 and 3, then these beams are placed in the rails, the movable upper beam 3 being engaged first and push up. The fixed lower beam 2 is fixed on the rails and the ends of the tension cables 51 and 52 are fixed to the movable upper beam 3 by passing these cables over the pulleys 53 and the assembly of the clamping device is completed shown in Figure 7, the winch 55 being disposed below the fixed beam on the support so as to be easily accessible.

L'écran opaque 30 est mis en place dans les rails 4 et 5.The opaque screen 30 is placed in the rails 4 and 5.

Si on désire réaliser un panneau d'affichage lumineux, on fixe, sur la face arrière de chaque poutre, une source lumineuse, de préférence linéaire, telle qu'un tube à décharge gazeuse, qui illumine la zone comprise entre le panneau souple 1 et l'écran opaque 30.If you want to create a luminous display panel, you fixed, on the rear face of each beam, a light source, of preferably linear, such as a gas discharge tube, which illuminates the area between the flexible panel 1 and the screen opaque 30.

On procède ensuite à la mise en place du panneau souple 1 sur les poutres 2 et 3 en faisant glisser le jonc 10 dans le logement 11 prévu à cet effet.We then proceed to the installation of the flexible panel 1 on beams 2 and 3 by sliding the rod 10 into the housing 11 provided for this purpose.

Les taquets latéraux 23 du panneau souple 1 ont été préalablement insérés dans la glissière correspondante. Pour faciliter cette insertion, on prévoit en haut des rails 4 et 5 à l'entrée de la glissière, un dispositif de guidage en forme d'entonnoir qui amène les taquets dans la glissière. On effectue alors la mise sous tension horizontale du panneau souple 1 au moyen des dispositifs à cliquet 42, comme expliqué sur la figure 9.The lateral tabs 23 of the flexible panel 1 have been previously inserted into the corresponding slide. For facilitate this insertion, at the top of rails 4 and 5 at the entrance of the slide, a funnel-shaped guide device which bring the tabs into the slide. We then carry out the horizontal tension of the flexible panel 1 by means of the devices pawl 42, as explained in FIG. 9.

Il suffit ensuite d'actionner le treuil 55 pour faire monter la poutre mobile 3 et le panneau souple 1 et on actionne ce treuil jusqu'à ce que l'on ait obtenu une tension importante sur la toile souple 1.Then simply activate the winch 55 to raise the movable beam 3 and flexible panel 1 and this winch is operated until a significant tension has been obtained on the canvas flexible 1.

On voit que, par un seul mouvement du treuil, on réalise une tension parfaite du panneau souple dans les deux directions verticale et horizontale.We see that, with a single movement of the winch, we realize perfect tension of the flexible panel in both directions vertical and horizontal.

Si l'on désire remplacer le panneau souple 1, cette opération est aisée puisqu'il suffit de détendre ce panneau, de le dégager des rails et des poutres et de mettre en place un nouveau panneau comportant un nouveau message.If one wishes to replace the flexible panel 1, this operation is easy since it suffices to relax this panel, to clear rails and beams and set up a new sign with a new message.

On voit donc que l'invention permet d'obtenir un panneau d'affichage de structure simple dans lequel on réalise une tension parfaite du panneau souple dans les deux directions verticale et horizontale, ce qui permet d'éviter toutes déformations et, par conséquent, d'obtenir une très bonne lisibilité du message porté par le panneau.It can therefore be seen that the invention makes it possible to obtain a panel simple structure display in which a voltage is produced perfect flexible panel in both vertical and horizontal, which avoids any deformation and, by Consequently, to obtain a very good readability of the message carried by the panel.

Par ailleurs, le système de réalisation de la tension horizontale des bords du panneau souple sur les poutres permet de réaliser des panneaux d'affichage qui présentent un profil non rectiligne, la poutre présentant alors le profil désiré, on peut ainsi réaliser des panneaux présentant des profils courbes ou angulaires qui ne présentent pas de déformations latérales.In addition, the tension realization system horizontal edges of the flexible panel on the beams allows make display panels that have a non-profiled straight, the beam then having the desired profile, we can thus make panels with curved or angular profiles which do not show lateral deformations.

L'écran opaque permet de protéger le panneau souple et peut être utilisé comme panneau d'affichage de fond. Par ailleurs, sa face interne peut être réfléchissante dans le cas où on utilise un dispositif d'éclairage rayonnant dans l'espace aménagé entre le panneau souple et l'écran opaque.The opaque screen protects the flexible panel and can be used as a background display panel. Furthermore, his internal face may be reflective in the case where a radiant lighting device in the space between the flexible panel and opaque screen.
