Abstract

The frame (1) is made in two sections (2d,2g) which can pivot about a central vertical axis so they can occupy two different positions, one at an angle to one another for fitting the fabric layer and a second in a straight line for stretching it. The fabric is in the form of a cover with end pouches (91,92) to engage with the frame sections when they are set at an angle to one another, each frame section having a curved member (27) at its end to give the fabric cover a predetermined shape when stretched. The frame sections also have locking members to retain them in the deployed position and can incorporate light or sound systems.

Description

La présente invention concerne un dispositif support de toile sous tension, et plus particulièrement un dispositif repliable.The present invention relates to a support device of canvas under tension, and more particularly a folding device.

L'invention concerne également l'application d'un tel dispositif à la réalisation d'un panneau d'affichage, notamment d'un panneau mural.The invention also relates to the application of a such a device for producing a display panel, including a wall panel.

Dans le cadre de l'invention, le terme "panneau d'affichage" doit être entendu dans son acceptation la plus large. Il englobe notamment les enseignes de magasin, les panneaux publicitaires, les caissons lumineux, etc. Pour fixer les idées, et sans que cela soit limitatif en quoi que ce soit de la portée de l'invention, on se placera ci-après dans le cadre de cette application de l'invention (panneaux et enseignes publicitaires), sauf indication contraire.In the context of the invention, the term "panel display "should be understood in its most large. It includes in particular store signs, billboards, light boxes, etc. For fix ideas, and without being limiting in any way this is the scope of the invention, we will place ourselves below in the context of this application of the invention (panels and advertising signs), unless otherwise indicated.

De même le terme "toile" englobe de nombreuses natures de matériaux : bâche, toile laquée ou non, etc.Likewise the term "canvas" encompasses many material types: tarpaulin, lacquered or uncoated canvas, etc.

De nombreux dispositifs formant support de toile tendue sont connus. Ils comprennent essentiellement deux sous-ensembles principaux : une ossature rigide, généralement en tubes creux, éventuellement complétée de renforts, et la toile de recouvrement, sous différentes formes : chaussette, housse, etc. Ces deux sous-ensembles sont généralement complétés par des organes de fixation de la toile, permanents ou démontables (tendeurs, "sandows", etc.). Ces dispositifs présentent l'avantage d'être plus légers que des structures comparables en matériau classique : tôle, etc., et sont généralement d'un prix de revient moins élevé. Many canvas support devices tense are known. They basically include two main subsets: a rigid frame, generally in hollow tubes, possibly supplemented with reinforcements, and the cover fabric, under different shapes: sock, cover, etc. These two subsets are generally supplemented by fasteners the canvas, permanent or removable (stretchers, "bungee cords", etc.). These devices have the advantage of being more lightweight than comparable structures of material classic: sheet metal, etc., and are generally priced at comes back lower.

Cependant, il existe un certain nombre de difficultés inhérentes à l'utilisation des structures souples de recouvrement constituées par des toiles.However, there are a number of difficulties inherent in the use of structures flexible covering constituted by fabrics.

Un premier problème rencontré dans l'art connu est d'obtenir une tension homogène de la toile, notamment dans ses parties visibles, de manière à ce que la surface soit exempte de plis inesthétiques (en particulier dans les applications publicitaires ou signalisation). Cette exigence est d'ailleurs plus difficile à obtenir pour certaines sections de panneaux (formes bombées).A first problem encountered in the known art is to obtain a homogeneous tension of the fabric, in particular in its visible parts, so that the surface is free from unsightly wrinkles (especially in advertising or signage applications). This requirement is more difficult to obtain for some panel sections (curved shapes).

On peut certes utiliser des tendeurs ou organes similaires, comme il vient d'être rappelé, ou des tôles sous-jacentes, mais toutes ces mesures entraínent une augmentation du prix, rendent plus complexe la structure et, éventuellement, augmentent son poids de façon non négligeable.We can certainly use tensioners or organs similar, as just mentioned, or sheets underlying, but all of these measures lead to a increase in price, make the structure more complex and, possibly increase their weight negligible.

Un deuxième problème est lié à la difficulté de mise en place (pose et dépose) de la toile sur l'ossature rigide du dispositif et au temps nécessaire pour cette opération. La difficulté précitée et le temps nécessaire dépendent naturellement des dimensions du panneau mais aussi, à dimensions égales, de la configuration de la toile (chaussette, housse, etc.), ainsi que de la nécessité ou non de disposer des tendeurs. Cette dernière opération, en augmentant le temps de mise en place, augmente corrélativement les coûts de main d'oeuvre.A second problem is related to the difficulty of setting in place (installation and removal) of the canvas on the rigid frame of the device and the time required for this operation. The above difficulty and the time required depend naturally of the dimensions of the panel but also, at equal dimensions, of the canvas configuration (sock, cover, etc.), as well as whether or not to have tensioners. This last operation, in increasing the set-up time, increases correlatively labor costs.

On peut enfin signaler que la structure adoptée pour la toile n'est pas sans incidence sur son prix de revient. A titre d'exemple, s'il est nécessaire de prévoir des tendeurs élastiques, de type "sandow", il est également nécessaire de réaliser dans la toile, au stade de la fabrication, des orifices renforcés par des oeillets métalliques. We can finally point out that the structure adopted for the canvas is not without impact on its cost price. AT example, if it is necessary to provide tensioners elastic, of the "bungee cord" type, it is also necessary to realize in the canvas, at the manufacturing stage, holes reinforced with metal eyelets.

Il est donc nécessaire de résoudre au mieux les problèmes qui viennent d'être rappelés. Mais il est utile de noter qu'un certain nombre de besoins se font sentir, notamment parmi les utilisateurs de ce type de dispositif et parmi lesquels :It is therefore necessary to best resolve the problems which have just been recalled. But it is useful to note that a number of needs arise, especially among users of this type of device and among which :

Il est tout d'abord souhaitable que, pour de nombreuses applications, la toile de recouvrement soit démontable, et éventuellement interchangeable. Elle doit pouvoir être nettoyée. Une toile laquée, par exemple, peut être nettoyée in situ. Ce n'est généralement pas le cas d'une toile non laquée. En cas de dégradation ou si l'on veut changer les indications (message, image, etc.) portées par le panneau, c'est-à-dire la partie visible de la toile, il est généralement nécessaire de remplacer la toile de recouvrement en son entier.It is first of all desirable that, for many applications, the covering fabric be removable, and possibly interchangeable. It must be able to be cleaned. Lacquered canvas, for example, can be cleaned in situ . This is generally not the case for an unpainted canvas. In case of damage or if you want to change the indications (message, image, etc.) carried by the panel, that is to say the visible part of the canvas, it is generally necessary to replace the covering fabric in its entirety.

Il est également souhaitable, même si le panneau est disposé à un emplacement fixe ou définitif, que les opérations de montage (et de démontage éventuel) puissent être réalisées dans un temps restreint, par un personnel sans qualification spécifique et avec un outillage réduit, voire sans outillage du tout, ce qui diminue fortement les frais liés à ces opérations. Il s'ensuit que la structure doit être de manipulation simple et présenter toute sécurité, pour les utilisateurs ou le public, tout en permettant une bonne tension de la toile de recouvrement qui évite tous plis inesthétiques.It is also desirable, even if the panel is placed in a fixed or permanent location, that the assembly operations (and possible disassembly) can be carried out in a limited time, by personnel without specific qualifications and with reduced tools, even without tools at all, which greatly reduces costs related to these operations. It follows that the structure must be simple to handle and present all security, for users or the public, while allowing a good tension of the cover fabric which avoids any unsightly folds.

Enfin, la section des panneaux doit pouvoir prendre différentes formes, de façon à réaliser des panneaux de forme plate, bombée, etc.Finally, the panel section must be able to take different shapes, so as to make panels of flat, curved shape, etc.

On doit également pouvoir disposer à l'intérieur ou à l'extérieur de l'ossature rigide du dispositif des sources lumineuses, voire des sources sonores (haut-parleurs, etc.). We must also be able to arrange inside or outside the rigid framework of the source device lights, or even sound sources (speakers, etc.).

L'invention se fixe pour but de répondre simultanément à ces besoins, dont certains semblent, a priori, antinomiques, tout en palliant les difficultés rencontrées dans l'art connu.The invention sets itself the goal of simultaneously meeting these needs, some of which seem, a priori, contradictory, while overcoming the difficulties encountered in the known art.

Pour ce faire, selon une première caractéristique de l'invention, le dispositif support de toile tendu selon l'invention comporte une ossature rigide, comprenant deux cadres repliables, à articulation médiane. Cette ossature est munie d'organes de blocage dans des zones d'extrémité, verrouillant, de façon réversible, les deux cadres en position dépliée. Les extrémités de ces cadres sont munies d'arceaux de forme appropriée qui serviront à définir la section du panneau, c'est-à-dire sa forme (plate ou bombée).To do this, according to a first characteristic of the invention, the fabric support device stretched according to the invention comprises a rigid frame, comprising two folding frames, with central articulation. This frame is fitted with locking members in end zones, reversibly locking the two frames in unfolded position. The ends of these frames are provided appropriately shaped arches which will be used to define the section of the panel, i.e. its shape (flat or curved).

Avantageusement, la toile de recouvrement de la structure est du type housse, c'est-à-dire comporte des replis sous forme de poches aux deux extrémités, poches qui s'enfilent simplement sur les extrémités des deux demi-cadres, en position repliée. Il suffit alors de déplier les deux cadres et de les verrouiller dans cette position. On obtient alors automatiquement et simplement la mise sous tension recherchée de la toile de recouvrement et sa mise en forme.Advantageously, the cover fabric of the structure is of the cover type, i.e. has folds in the form of pockets at both ends, pockets which simply slip on the ends of the two half-frames, in the folded position. Then simply unfold the two frames and lock them in this position. We then automatically and simply obtains the desired tension of the covering fabric and its setting form.

Dans un mode de réalisation préféré de l'invention, au moins l'une des extrémités de cadre, c'est-à-dire au moins l'une des extrémités de la structure porteuse, est munie d'un organe d'extension télescopique réglable. Cette disposition permet d'obtenir une tension ajustable de la toile et/ou d'accommoder des disparités ou variations de dimension de celle-ci.In a preferred embodiment of the invention, at least one of the frame ends, i.e. at the minus one of the ends of the supporting structure, is fitted with an adjustable telescopic extension member. This arrangement provides an adjustable tension of the canvas and / or accommodate disparities or variations in dimension of it.

Toujours dans un mode de réalisation préféré de l'invention, le dispositif support est associé à des organes de levage permettant de la placer à hauteur voulue sur un plan vertical, par exemple le mur d'un magasin ou d'un bâtiment similaire.Still in a preferred embodiment of the invention, the support device is associated with organs lifting to place it at the desired height on a vertical plane, for example the wall of a shop or similar building.

L'invention a donc pour objet un dispositif support de toile tendue comprenant une ossature rigide, ladite toile recouvrant au moins une face dite principale de cette ossature, caractérisé en ce que ladite ossature comprend deux cadres mobiles en rotation autour d'un axe, de manière à ce que lesdits deux cadres soient susceptibles de prendre une première position spatiale, dite dépliée, pour laquelle ils sont sensiblement dans le prolongement l'un de l'autre et présentent un débattement maximal, et une seconde position spatiale, dite repliée, pour laquelle les deux cadres forment entre eux un angle d'amplitude déterminée, et en ce que ladite toile comprend des moyens d'accrochage permettant de l'arrimer sur les cadres, lorsqu'ils sont placés dans ladite position repliée, et en ce qu'elle est mise sous tension automatiquement lorsque les cadres sont replacés dans ladite position dépliée, les extrémités des cadres exerçant une force de traction longitudinale sur celle-ci, dans cette position dépliée.The invention therefore relates to a support device stretched canvas comprising a rigid frame, said canvas covering at least one so-called main face of this frame, characterized in that said frame comprises two movable frames rotating around an axis, so that said two executives are likely to take a first spatial position, called unfolded, for which they are substantially in line with one another and have maximum travel, and a second spatial position, known as folded, for which the two frames form between them an angle of determined amplitude, and in that said fabric comprises hooking means allowing it to be secured on the frames, when they are placed in said folded position, and in that it is power on automatically when frames are replaced in said unfolded position, the ends of the frames exerting a longitudinal tensile force on this one, in this unfolded position.

L'invention a encore pour objet l'application d'un tel dispositif pour la réalisation de panneaux d'affichage.The invention also relates to the application of a such a device for the production of display panels.

Le dispositif selon l'invention présentent donc de nombreux avantages, notamment une structure légère et une grande simplicité de mise en oeuvre. Il permet des opérations de mise en place ou de dépose de la toile très rapides, tout en obtenant une tension de la toile appropriée et un état de surface de grande qualité, ce sans augmentation significative du prix de fabrication.The device according to the invention therefore have many advantages, including a light structure and great simplicity of implementation. It allows operations of placing or removing the canvas very fast, while obtaining an appropriate fabric tension and a high quality surface finish, without significant increase in the manufacturing price.

On va maintenant décrire un exemple de réalisation d'un dispositif 1, support de toile tendue selon un mode de réalisation préféré de l'invention, par référence aux figures 1a à 2f.We will now describe an exemplary embodiment of a device 1, canvas support stretched according to a method of preferred embodiment of the invention, with reference to Figures 1a to 2f.

La figure la illustre, en perspective, l'ossature rigide du support de toile tendue, cette toile 9 (voir par exemple figure 1b) n'étant pas mise en place sur le support.The figure illustrates it, in perspective, the framework rigid of the stretched canvas support, this canvas 9 (see par example Figure 1b) not being placed on the support.

Pour fixer les idées, on suppose que le panneau qui sera obtenu après mise en place de la toile 9 est un panneau allongé, disposé suivant une direction sensiblement horizontale, sans que cela limite en quoi que ce soit la portée de l'invention. On parlera donc dans ce qui suit, de façon purement arbitraire, de côté gauche et de côté droit, différenciés ci-après par les lettres "g" et "d".To fix the ideas, we suppose that the panel which will be obtained after placement of the canvas 9 is a panel elongated, arranged in a substantially horizontal direction, without limiting in any way the scope of the invention. We will therefore speak in what follows, so purely arbitrary, left side and right side, differentiated below by the letters "g" and "d".

Selon une première caractéristique importante de l'invention, le support comprend deux cadres, un cadre droit 2d et un cadre gauche, 2g, articulés autour d'un montant vertical 20, de façon plus précise, autour d'axes de rotation 200 et 201, disposés aux extrémité de celui-ci. Ces deux cadres 2g et 2d, peuvent donc se replier vers l'avant, au moins partiellement, par rotation. Il s'ensuit que la longueur totale de la projection sur un plan vertical est comprise entre une valeur maximale, obtenue pour les cadres 2g et 2d, dépliés (c'est-à-dire compris dans un même plan) et une longueur minimale, obtenue pour les cadres repliés partiellement (les plans des cadres 2g et 2d, formant un angle différent de 180 degrés). Ce premier mécanisme, à lui seul, permet de tendre une toile 9 qui sera enfilée sur les deux extrémités, de la manière décrite en regard de la figure 1b.According to a first important characteristic of the invention, the support comprises two frames, a frame right 2d and a left frame, 2g, articulated around a vertical post 20, more precisely, around axes of rotation 200 and 201, arranged at the end thereof. These two frames 2g and 2d, can therefore be folded forward, at least partially, by rotation. It follows that the total length of the projection on a vertical plane is between a maximum value, obtained for frames 2g and 2d, unfolded (i.e. included in the same plane) and a minimum length, obtained for folded frames partially (the plans of frames 2g and 2d, forming a angle other than 180 degrees). This first mechanism, to him only, allows to stretch a fabric 9 which will be threaded on the two ends, as described opposite the Figure 1b.

Selon une autre caractéristique de l'invention, on prévoit des organes de blocage 6g et 6d, disposés de part et d'autre du montant central d'articulation 20, et permettant de verrouiller, de façon réversible, les cadres 2g et 2d, en position dépliée (longueur maximale).According to another characteristic of the invention, one provides locking members 6g and 6d, arranged on the side and other of the central articulation 20, and allowing to lock, reversibly, the frames 2g and 2d, in unfolded position (maximum length).

Selon une autre caractéristique de l'invention, et dans un mode de réalisation préféré, on prévoit au moins un organe supplémentaire 4, permettant d'ajuster la tension. Il se présente sous la forme d'un organe d'extension télescopique réglable disposé à l'une des extrémités, en l'occurrence l'extrémité droite dans l'exemple décrit.According to another characteristic of the invention, and in a preferred embodiment, at least one additional member 4, for adjusting the tension. he comes in the form of an extension organ adjustable telescopic disposed at one end, in the occurrence of the right end in the example described.

Enfin, selon une caractéristique supplémentaire, également dans un mode de réalisation préféré, le dispositif support 1 est associé à des organes de suspension et de levage réglables, représentés sous les références 7 et 8, et qui seront détaillés ci-après.Finally, according to an additional characteristic, also in a preferred embodiment, the device support 1 is associated with suspension and adjustable lifting, shown under references 7 and 8, and which will be detailed below.

On va maintenant décrire de façon plus précise les différents composants du dispositif support 1, toujours par référence à la figure 1a. We will now describe more precisely the different components of the support device 1, always by reference to Figure 1a.

Les cadres 2g et 2d, comprennent chacun deux tubes horizontaux, un tube supérieur, respectivement 21 et 23, et un tube inférieur, respectivement 22 et 24, dont les extrémités situées dans la zone centrale du dispositif 1 sont mécaniquement liées aux axes de rotation 200 et 201.The frames 2g and 2d, each include two tubes horizontal, an upper tube, respectively 21 and 23, and a lower tube, respectively 22 and 24, the ends located in the central zone of the device 1 are mechanically linked to the axes of rotation 200 and 201.

L'extrémité gauche du dispositif 1, qui ne comporte pas d'organe d'extension télescopique 4 dans l'exemple décrit, se termine par un montant tubulaire vertical 25 et un arceau 27 de forme appropriée, disposé dans un plan perpendiculaire au plan du cadre 2g. C'est cet arceau 27 qui va imposer une forme prédéterminée à la face visible du panneau, c'est-à-dire par convention la face avant. Dans l'exemple décrit sur la figure 1a, il a la forme d'une portion d'ellipse.The left end of the device 1, which does not include no telescopic extension member 4 in the example described, ends with a vertical tubular upright 25 and a hoop 27 of suitable shape, arranged in a plane perpendicular to the plane of the frame 2g. It is this hoop 27 which will impose a predetermined shape on the visible face of the panel, that is to say by convention the front face. In the example described in Figure 1a, it has the shape of a portion of ellipse.

L'extrémité droite du dispositif 1 est plus complexe, car elle comporte l'organe d'extension télescopique 4. Le cadre de droite 2d est en réalité constitué d'un cadre fixe qui se prolonge par un cadre télescopique de plus petite dimension. Le cadre fixe comprend deux tubes horizontaux 23 et 24, réunis, en leur extrémité opposée au montant central 20, par un montant tubulaire vertical 26.The right end of device 1 is more complex because it includes the extension organ telescopic 4. The right frame 2d is actually consisting of a fixed frame which is extended by a frame telescopic smaller. The fixed frame comprises two horizontal tubes 23 and 24, joined together, in their opposite end to the central upright 20, by an upright vertical tubular 26.

Le cadre formant l'organe d'extension télescopique 4 a la même hauteur que les cadres principaux 2g et 2d. Les tubes horizontaux 41 et 42 du cadre formant l'organe d'extension télescopique 4 s'enfilent, par l'une de leurs extrémités 410 et 420, de diamètre réduit, dans les tubes 23 et 24, respectivement, que l'on suppose creux. Le cadre est complété par deux montants tubulaires verticaux 45 et 44. Le tube 44, disposé à l'extrémité gauche du dispositif 1, joue un rôle similaire au tube d'extrémité gauche 25. Il est également prévu un arceau d'extrémité 43, de même forme que l'arceau 27 et jouant un rôle identique à ce dernier. The frame forming the telescopic extension member 4 has the same height as the main frames 2g and 2d. The horizontal tubes 41 and 42 of the frame forming the member telescopic extension 4 thread, by one of their ends 410 and 420, of reduced diameter, in the tubes 23 and 24, respectively, which are assumed to be hollow. The frame is completed by two vertical tubular uprights 45 and 44. The tube 44, arranged at the left end of device 1, plays a role similar to the left end tube 25. It is also provided an end arch 43, of the same shape as the arch 27 and playing an identical role to the latter.

Un système de réglage, par exemple deux vis ou tiges filetées 40a et 40b, enfilées dans des orifices filetés (non représentés) prévus dans les montants 26 et 45, permet de les rapprocher ou de les éloigner à volonté. Il s'ensuit que, par glissement guidé des tubes 410 et 420, dans les extrémités des tubes 23 et 24, l'organe d'extension télescopique 4 s'écarte ou se rapproche du centre du dispositif 1, c'est-à-dire du montant 20, axe de rotation des cadres 2g et 2d. Il est à noter que l'organe d'extension télescopique 4 reste toujours dans le prolongement du cadre 2d, quelle que soit sa position dans l'espace (état déplié ou replié du cadre 2d).An adjustment system, for example two screws or rods threaded 40a and 40b, threaded in threaded holes (not shown) provided in amounts 26 and 45, allows bring them together or move them away at will. It follows that, by guided sliding of the tubes 410 and 420, in the ends of tubes 23 and 24, the extension member telescopic 4 deviates or approaches the center of the device 1, i.e. upright 20, axis of rotation 2g and 2d frames. It should be noted that the extension member telescopic 4 always remains in the extension of the frame 2d, whatever its position in space (unfolded state or folded back from frame 2d).

Un outil simple (tournevis, clé ou similaires) permet d'actionner le système de réglage à vis 40a et 40b. Ce réglage permet d'ajuster la longueur cumulée des deux cadres à l'état dépliée (le cadre de droite étant constitué du cadre 2d proprement dit et du cadre de l'organe d'extension télescopique 4), c'est-à-dire la longueur maximale.A simple tool (screwdriver, wrench or the like) activates the screw adjustment system 40a and 40b. This setting adjusts the cumulative length of the two unfolded frames (the right frame being made up of the 2d frame proper and of the organ frame telescopic extension 4), i.e. the length maximum.

La longueur totale l t du dispositif 1 est donc donnée par la formule : l t = l 1 + l 2 + l + Δl ; avec l 1 longueur du cadre gauche 2g, 12 longueur du cadre droit 2d, l longueur de la partie fixe du cadre de l'organe d'extension télescopique (tubes 41 et 42) et Δl l'amplitude de l'ajustement possible à l'aide des vis 40a et 40b, compris entre 0 et une valeur maximale prédéterminée Δlmax . Il est à noter que les longueurs relatives des cadres gauche et droit, 2g et 2d, sont sans importance, même si dans un exemple de réalisation pratique on choisit de préférence : l 1 ≅ l 2 + l.The total length l t of device 1 is therefore given by the formula: l t = l 1 + l 2 + l + Δ l ; with l 1 length of the left frame 2g, 12 length of the right frame 2d, l length of the fixed part of the frame of the telescopic extension member (tubes 41 and 42) and Δ l the amplitude of the possible adjustment to using screws 40a and 40b, between 0 and a predetermined maximum value Δ l max . It should be noted that the relative lengths of the left and right frames, 2g and 2d, are unimportant, even if in an example of practical realization one chooses preferably: l 1 ≅ l 2 + l .

Dans une autre variante de réalisation, non représentée, le système de réglage à vis peut être remplacé par un système de réglage à ressorts. Ces ressorts sont disposés entre le cadre principal 2d (dans l'exemple décrit) et l'organe télescopique 4. Les ressorts sont normalement à l'état compressé lorsque les cadres 2d et 2g sont dépliés et la toile 9 tendue. Il s'ensuit que, si l'état de tension de celle-ci vient à se modifier, par exemple en raison de variations de la température extérieure (contraintes thermiques), lentes ou brutales, l'ajustement en tension de la toile 9 s'effectue de façon automatique. Il s'ensuit également qu'il n'est plus nécessaire de disposer d'un outillage particulier.In another alternative embodiment, not shown, the screw adjustment system can be replaced by a spring adjustment system. These springs are arranged between the main frame 2d (in the example described) and the telescopic member 4. The springs are normally at the compressed state when the 2d and 2g frames are unfolded and canvas 9 stretched. It follows that, if the tension state of it changes, for example due to variations in outside temperature (constraints thermal), slow or brutal, the voltage adjustment of the fabric 9 is carried out automatically. It follows also that it is no longer necessary to have a special tools.

Dans une autre variante encore (non représentée), le système de réglage d'extrémité peut être remplacé par un organe du type pignon-crémaillère, muni d'un système irréversible déverrouillable.In yet another variant (not shown), the end adjustment system can be replaced with a rack and pinion type device, provided with a system irreversible unlockable.

On prévoit également, comme il a été indiqué, des organes de blocage et plus précisément deux organes de blocage 6g et 6d, disposés près des extrémités des cadres 2g et 2d. Ces organes comprennent, chacun, un arbre vertical 60, susceptible de rotation dans deux paliers 601 et 602. Cet arbre 60 entraíne, dans sa rotation, un crochet de blocage 600. Les deux organes de blocage 6g et 6d, sont reliés mécaniquement par une barre de liaison horizontale 5. Plus précisément, cette barre de liaison 5 relie (dans l'exemple décrit) les paliers inférieurs 601. Comme il le sera décrit ci-après, cette barre 5 relie également des organes de guidage 604, dont l'utilité sera précisée.As noted, there are also plans to blocking organs and more precisely two organs of blocking 6g and 6d, arranged near the ends of the 2g frames and 2d. These organs each include a tree vertical 60, capable of rotation in two bearings 601 and 602. This shaft 60 causes, in its rotation, a hook blocking device 600. The two blocking members 6g and 6d are mechanically connected by a horizontal link bar 5. More specifically, this link bar 5 connects (in the example describes) the lower bearings 601. As it will be described below, this bar 5 also connects guide members 604, the usefulness of which will be specified.

Les crochets de blocage 600 coopèrent avec des tringles de blocage 61, solidaires des cadres droit et gauche 2g et 2d. Plus précisément, les tringles se présentent sous la forme de montants verticaux reliant les tubes horizontaux supérieurs 21 et 23, aux tubes horizontaux inférieurs 22 et 24. Elles comprennent également, dans une zone centrale, des organes centreurs 610 destinés à recevoir les crochets 600. The locking hooks 600 cooperate with locking rods 61, integral with the right frames and left 2g and 2d. More specifically, the rods are are in the form of vertical uprights connecting the upper horizontal tubes 21 and 23, to the horizontal tubes lower 22 and 24. They also include, in a central area, centralizing organs 610 intended to receive hooks 600.

La rotation des arbres 60 dans leurs paliers 601 et 602, est sous la commande de poignées 603, disposées à leur extrémité supérieure (dans l'exemple décrit sur la figure 1a). De façon avantageuse, les cadres 2g et 2d, sont verrouillés à l'état déplié lorsque les poignées 603 sont parallèles aux cadres, par exemple toutes deux tournées vers la droite, comme illustré sur la figure la. Lorsqu'on effectue une rotation suffisante des poignées 603, par exemple un quart ou un demi-tour, les crochets se désengagent des organes centreurs 610 et relâchent les tringles de blocage 61. Ces organes centreurs 610 permettent d'atténuer les efforts imposés aux axes 200 et 201. Les deux cadres 2g et 2d (ou un seul de ces cadres, si une seule poignée 603 est actionnée) sont alors libres et l'on peut les replier par rotation autour des axes 200 et 201.The rotation of the shafts 60 in their bearings 601 and 602, is under the control of handles 603, arranged at their upper end (in the example described on the Figure 1a). Advantageously, the frames 2g and 2d are locked in the unfolded state when the handles 603 are parallel to the frames, for example both facing the right, as illustrated in figure la. When we performs sufficient rotation of the handles 603, by example a quarter or a half-turn, the hooks are disengage centralizing organs 610 and release the locking rods 61. These centralizing members 610 allow mitigate the efforts imposed on axes 200 and 201. Both 2g and 2d frames (or only one of these frames, if only one handle 603 is activated) are then free and you can fold them back by rotation around axes 200 and 201.

Pour éviter un repliement trop important, qui s'avère inutile comme il le sera montré, on prévoit avantageusement des compas 3g et 3d, un pour chaque cadre 2g et 2d, reliant par leurs bras 30 et 31, la barre de liaison 5 et les tubes horizontaux inférieurs, 22 et 24, respectivement. L'amplitude du repliement des cadres, 2g et 2d, est alors limitée à une valeur prédéterminée. Cette disposition renforce la sécurité apportée par le dispositif selon l'invnetion. Elle évite un repliement complet intempestif des deux cadres, 2d et 2g, qui risquerait de blesser des personnes se trouvant à proximité ou d'occasionner des dégâts à des véhicules proches.To avoid excessive folding, which proves useless as it will be shown, we plan preferably 3g and 3d compasses, one for each 2g frame and 2d, connecting by their arms 30 and 31, the connecting bar 5 and the lower horizontal tubes, 22 and 24, respectively. The amplitude of the folding of the frames, 2g and 2d, is then limited to a predetermined value. This provision reinforces the security provided by the device according to the invnetion. It avoids complete folding two frames, 2d and 2g, which would risk injuring people in the vicinity or cause damage to nearby vehicles.

L'application principale du dispositif support 1 selon l'invention est la réalisation de panneaux publicitaires ou d'enseignes accolés à des murs. Pour ce faire, on associe au support 1 des organes d'accrochage et de levage. A titre d'exemple non limitatif, comme le montre la figure la, on prévoit des glissières 7 et des câbles de suspension 8. The main application of the support device 1 according to the invention is the production of advertising panels or signs attached to walls. To do this, we associates with the support 1 hooking and lifting members. By way of nonlimiting example, as shown in the figure there, there are provided slides 7 and suspension cables 8.

Les arbres de blocage 60, et plus précisément leurs paliers 601 et 602, car ces derniers sont fixes dans l'espace, sont munis de pièces d'accrochage 604 et 605, également liées mécaniquement à la barre de liaison 5 et insérées dans des rainures 70 réalisées dans les glissières 7. Il en est de même du montant central 20 qui comporte une pièce d'accrochage 203, liée à la barre de liaison 5, et insérée dans la rainure 70 d'une glissière 7.The blocking shafts 60, and more precisely their bearings 601 and 602, because the latter are fixed in space, are fitted with hooking pieces 604 and 605, also mechanically linked to link bar 5 and inserted into grooves 70 made in the slides 7. The same applies to the central upright 20 which includes a hooking piece 203, linked to the bar link 5, and inserted into the groove 70 of a slide 7.

Les câbles de suspension 8 permettent la dépose du dispositif support 1 complet et sa remontée à une position appropriée sur le mur, ce à l'aide de dispositifs classiques (non représentés), treuils ou autres engins similaires. Pour ce faire, les câbles entraínent les pièces d'accrochage 203, 604 et 605 et les font glisser dans les rainures 70. Si la structure est verticale, le poids de celle-ci, l'entraínant vers le bas, est normalement suffisant pour l'opération de dépose.The suspension cables 8 allow the removal of the support device 1 complete and its ascent to a position suitable on the wall, using conventional devices (not shown), winches or other similar gear. For to do this, the cables drive the attachment pieces 203, 604 and 605 and slide them into the grooves 70. If the structure is vertical, the weight of it, driving down, is normally sufficient for the operation of deposit.

Dans une variante préférée de l'invention, la toile de recouvrement est du type "housse" comme le montre plus particulièrement la figure de détail 1b.In a preferred variant of the invention, the canvas cover is of the "cover" type as shown more particularly the detail figure 1b.

En effet, toujours dans l'application préférée, le dispositif support 1 étant accolé à un mur, seule l'une des faces du panneau est visible. Il suffit donc de prévoir, à chaque extrémité du dispositif 1 (sur la figure 1b, seule l'extrémité gauche a été représentée), une poche s'enfilant sur les extrémités des cadres 2g et 2d, plus précisément sur les arceaux 27 et 43 (figure 1a).Indeed, still in the preferred application, the support device 1 being attached to a wall, only one of the sides of the panel is visible. It is therefore sufficient to provide, at each end of the device 1 (in FIG. 1b, only the left end has been shown), a threading pocket on the ends of frames 2g and 2d, more precisely on arches 27 and 43 (Figure 1a).

Comme le montre la figure 1b, la toile 9 comprend une face principale avant 90 et une face principale arrière 93. La poche précitée est réalisée par des replis de toile vers l'arrière. As shown in Figure 1b, the fabric 9 includes a main face before 90 and a main face rear 93. The aforementioned pocket is produced by folds of canvas back.

On doit bien comprendre que, comme il a été indiqué, c'est la forme des arceaux d'extrémité 27 et 43 qui impose la forme de la face avant du panneau lorsqu'il est recouvert de toile. Aussi, la longueur de la toile 9 est égale ou légèrement supérieure à l t (l'organe d'extension télescopique permettant un allongement de la structure au plus égal à Δlmax ). Sa largeur doit être au moins égale à la longueur de la périphérie des arceaux 27 et 43. En d'autres termes, la toile 9 sera plus large que les cadres 2g et 2d.It should be understood that, as has been indicated, it is the shape of the end arches 27 and 43 which imposes the shape of the front face of the panel when it is covered with canvas. Also, the length of the fabric 9 is equal to or slightly greater than l t (the telescopic extension member allowing an elongation of the structure at most equal to Δ l max ). Its width must be at least equal to the length of the periphery of the arches 27 and 43. In other words, the fabric 9 will be wider than the frames 2g and 2d.

Dans l'exemple décrit sur les figures 1a et 1b, le dispositif 1, recouvert de sa toile 9, présente une face bombée convexe.In the example described in FIGS. 1a and 1b, the device 1, covered with its fabric 9, has a face convex convex.

Les poches d'extrémité présentent donc une face plane de côté 91 et une face arrière repliée 92, également plane. La jonction avec la surface principale arrière 93 peut s'effectuer par tout procédé connu : collage, soudure, couture, etc., ce en tenant compte de la nature du matériau de la toile 9. On a représenté schématiquement les zones de jonction par des traits pointillés référencés 920.The end pockets therefore have one side side plane 91 and a folded back face 92, also plane. The junction with the rear main surface 93 can be done by any known process: bonding, welding, sewing, etc., taking into account the nature of the material of the fabric 9. The zones of junction by dotted lines referenced 920.

La cavité interne des poches d'extrémité a donc une section et des dimensions qui permettent de les enfiler sur les extrémités des cadres 2g et 2d.The internal cavity of the end pockets therefore has a section and dimensions that allow them to be threaded on the ends of frames 2g and 2d.

On va maintenant décrire les différentes opérations de dépose et de pose de la toile 9, par référence aux figures 2a à 2f.We will now describe the different operations removing and installing the fabric 9, with reference to Figures 2a to 2f.

Sur ces figures on a supposé que les arceaux avaient une forme identique à celle précédemment décrite, en l'occurrence une portion d'ellipse. En outre, pour simplifier les dessins, on n'a référencé que les éléments nécessaires à la bonne compréhension de l'invention. Enfin, on n'a pas représenté l'organe d'extension télescopique 4 (figure 1a). On doit d'ailleurs bien comprendre que cet organe n'est pas obligatoire, bien qu'il fasse partie intégrante d'un dispositif support 1 selon le mode de réalisation préféré de l'invention. Les éléments communs aux figures précédentes portent les mêmes références et ne seront redécrits qu'en tant que de besoin. On a seulement adjoint à certaines références les lettres "g" ou "d" pour différencier les pièces de la partie gauche, des pièces de la partie droite.In these figures it has been assumed that the hoops had a shape identical to that previously described, in the occurrence of an ellipse portion. In addition, for simplify the drawings, we only referenced the elements necessary for a good understanding of the invention. Finally, the telescopic extension member 4 has not been shown (Figure 1a). We must also understand that this organ is not mandatory, although it is part integral of a support device 1 according to the mode of preferred embodiment of the invention. The elements common to previous figures have the same references and do not will be re-described as necessary. We only have added to some references the letters "g" or "d" for differentiate the pieces on the left, pieces of the right side.

Sur la figure 2a, on a représenté le dispositif support 1 drapé de sa toile de recouvrement 9 tendue. La face principale visible 90 est bombée. Ceci constitue l'état que l'on peut appeler normal ou permanent.In Figure 2a, there is shown the device support 1 draped with its stretched covering fabric 9. The visible main face 90 is curved. This constitutes the state which can be called normal or permanent.

Si on désire déposer la toile 9, on agit sur les poignées supérieures, l'une après l'autre, par exemple en premier lieu la poignée de gauche, 603g. On lui fait effectuer au moins un quart de tour selon les aiguilles d'une montre (flèche), ce qui déverrouille le cadre de gauche (figure la : 2g) comme le montre plus particulièrement la figure 2b. On peut donc faire pivoter ce cadre gauche autour de l'articulation centrale (figure 1a : axes 200 et 201).If we wish to deposit the canvas 9, we act on the top handles, one after the other, for example in first place the left handle, 603g. We make him make at least a quarter turn according to the needles a watch (arrow), which unlocks the frame left (figure la: 2g) as shown more particularly Figure 2b. So we can rotate this frame left around the central joint (figure 1a: axes 200 and 201).

Sur cette même figure 2b, on déverrouille le cadre de droite (figure 1a : 2d) en agissant sur la poignée 603d, comme précédemment et on fait pivoter ce cadre. La longueur cumulée des deux cadres, projetée sur un plan vertical est donc réduite à une valeur minimale. On peut donc retirer la toile 9 (qui n'est plus tendue de ce fait) des cadres 2g et 2d, sur lesquels elle était posée. Pour ce faire, il suffit de la tirer par ses extrémités 91. Les poches glissent alors des arceaux (voir figure 1b : 27).On this same figure 2b, we unlock the frame right (Figure 1a: 2d) by acting on the handle 603d, as before and we rotate this frame. The length cumulative of the two frames, projected on a vertical plane is therefore reduced to a minimum value. So we can remove the canvas 9 (which is no longer stretched as a result) of the 2g frames and 2d, on which it was placed. To do this, just to pull it by its ends 91. The pockets then slide hoops (see Figure 1b: 27).

La figure 2c illustre l'état obtenu après dépose de la toile 9 (structure nue). On constate que les compas autorisent un repliement d'amplitude maximale : angle α avec la barre de liaison 5. La profondeur des poches d'extrémité ainsi que la valeur de l'angle α doivent être déterminées de manière à rendre possible le retrait de la toile 9 de ses cadres supports.FIG. 2c illustrates the state obtained after removal of canvas 9 (bare structure). We see that the compasses allow folding with maximum amplitude: angle α with the connecting bar 5. The depth of the end pockets as well as the value of the angle α must be determined from so as to make it possible to remove the canvas 9 from its support frames.

A partir de cet état, on peut remettre en place la même toile 9 ou encore une toile différente. Pour ce faire, comme illustré plus particulièrement par la figure 2d, on enfile l'une des poches d'extrémité sur l'extrémité d'un cadre, par exemple le cadre gauche 2g, puis l'autre extrémité, sur le cadre droit 2d. Cette opération a déjà été décrite en regard de la figure 1b.From this state, you can replace the same canvas 9 or a different canvas. To do this, as illustrated more particularly by FIG. 2d, we thread one of the end pockets over the end of a frame, for example the left frame 2g, then the other end, on the right frame 2d. This operation has already been described with reference to Figure 1b.

Sur la figure 2e, toute la toile 9 est posée et prête à être mise en tension. Pour ce faire, on rabat les cadres, les uns après les autres vers les organes de blocage 60 (figure 2c), par exemple le cadre de droite 2d, et on actionne la manette 603d dans le sens trigonométrique, jusqu'à l'obtention du verrouillage par le crochet de blocage 600d (figure 2d).In FIG. 2e, all of the fabric 9 is laid and ready to be tensioned. To do this, we fold the frames, one after the other towards the organs of blocking 60 (FIG. 2c), for example the right frame 2d, and we operate the joystick 603d counterclockwise, until the locking hook is obtained blocking 600d (figure 2d).

Ensuite, comme le montre la figure 2f, on rabat l'autre cadre, c'est-à-dire le cadre de gauche 2g (figure 2d) et on le verrouille à l'aide de l'organe de blocage 60g et du crochet 600g, ce en actionnant la manette 603d, comme précédemment.Then, as shown in Figure 2f, we fold the other frame, i.e. the left frame 2g (Figure 2d) and it is locked using the blocking 60g and hook 600g, by operating the joystick 603d, as before.

Ces opérations simples permettent d'obtenir automatiquement, à la fois une tension longitudinale correcte de la toile 9 et un aspect lisse de la surface principale 90.These simple operations provide automatically, both a longitudinal tension correct canvas 9 and a smooth appearance of the surface main 90.

Il est à noter que l'ensemble du processus, c'est-à-dire les phases représentées sur les figures 2a à 2f, s'effectuent typiquement dans un intervalle de temps inférieur à 2 minutes. Note that the whole process, that is to say the phases shown in FIGS. 2a to 2f, typically occur in a time interval less than 2 minutes.

Bien que l'on n'ait pas représenté l'organe d'extension télescopique 4 (figure 1a), comme il a été indiqué ci-dessus, il est possible encore d'ajuster la longueur totale du dispositif support 1, en agissant sur les organes de réglage de celui-ci, lorsqu'il existe. Cette opération peut s'effectuer, soit a priori lorsque la toile 9 est retirée (phase représentée sur la figure 2c), soit a posteriori lorsque la toile 9 est mise en place, les cadres 2g et 2d, étant dépliés et verrouillés dans cette position (phase représentée sur la figure 2f). La toile 9 est alors prétendue, et la tension définitive peut être obtenue en agissant, par derrière le panneau, sur les organes de réglage (figure 1a : 40a et 40b), à l'aide d'un outillage simple, une clé par exemple. On peut alors obtenir un réglage fin permettant, notamment, "d'effacer" des plis résiduels ou de tenir compte de disparités de dimensions, d'une toile à l'autre en cas de remplacement, ou encore d'un relâchement dans le temps.Although the telescopic extension member 4 has not been shown (FIG. 1a), as indicated above, it is still possible to adjust the total length of the support device 1, by acting on the adjustment members thereof, when it exists. This operation can be performed, either a priori when the fabric 9 is removed (phase shown in FIG. 2c), or a posteriori when the fabric 9 is put in place, the frames 2g and 2d, being unfolded and locked in this position (phase shown in Figure 2f). The fabric 9 is then pretended, and the final tension can be obtained by acting, behind the panel, on the adjustment members (FIG. 1a: 40a and 40b), using a simple tool, a wrench for example . We can then obtain a fine adjustment allowing, in particular, to "erase" residual folds or to take account of disparities in dimensions, from one canvas to another in the event of replacement, or even a relaxation over time. .

On constate aisément que les opérations de dépose et de pose de la toile 9, ainsi que sa mise sous tension sont particulièrement simples, ne nécessitent pas un outillage onéreux, ni a priori spécifique, et sont à la portée d'un personnel non spécialisé.It is easy to see that the operations of removing and installing the fabric 9, as well as putting it under tension are particularly simple, do not require expensive tools, or a priori specific, and are within the reach of non-specialized personnel.

Par ailleurs, l'ajustement est automatique si l'organe téléscopique 4 est du type à ressorts. Il n'est donc plus nécécesaire de disposer d'un outillage quelconque, comme il a été précédemment indiqué.In addition, the adjustment is automatic if the telescopic member 4 is of the spring type. It is not therefore no longer necessary to have any tools whatsoever, as previously stated.

La surface de la toile, outre sa couleur de fond, peut porter diverses inscriptions, logos ou dessins, en particulier lorsqu'il s'agit d'un panneau publicitaire ou d'une enseigne de magasin. Pour ce faire, de nombreux procédés connus sont utilisables. On peut citer notamment la pose d'adhésifs, les procédés par peinture, au rouleau ou au pinceau, la pose d'adhésifs avec impression numérique et l'impression numérique directe. Le choix d'un procédé particulier dépend naturellement de l'application spécifique et de la nature du matériau support, c'est-à-dire du matériau constitutif de la toile. Les impressions peuvent être réalisées au moment de la fabrication, voire in situ, du moins pour certains procédés.The surface of the canvas, in addition to its background color, can bear various inscriptions, logos or designs, in particular when it is a billboard or a shop sign. To do this, many known methods can be used. Mention may in particular be made of the application of adhesives, the paint, roller or brush processes, the application of adhesives with digital printing and direct digital printing. The choice of a particular process naturally depends on the specific application and the nature of the support material, that is to say the material of the canvas. Prints can be produced at the time of manufacture, or even in situ , at least for certain processes.

Dans une variante de réalisation non représentée, On peut incorporer dans l'ossature rigide une ou plusieurs source(s) de lumière, notamment en mettant en oeuvre des toiles diffusantes. De ce fait, on peut réaliser un caisson lumineux. On peut aussi y incorporer des sources sonores (haut-parleurs ou autres transducteurs électroacoustiques).In an alternative embodiment not shown, On can incorporate one or more into the rigid framework light source (s), in particular by implementing diffusing fabrics. Therefore, we can make a box luminous. You can also incorporate sound sources (speakers or other electroacoustic transducers).

Comme il a été indiqué, la forme convexe qui vient d'être décrite n'est pas la seule réalisable.As noted, the convex shape that comes to be described is not the only achievable.

Les figures 3a à 3c illustrent schématiquement des panneaux de sections diverses.Figures 3a to 3c schematically illustrate panels of various sections.

Sur la figure 3a, on a représenté partiellement un panneau la dont la surface principale 90a de la toile 9a est de forme parabolique, c'est-à-dire ayant une surface concave. Il est nécessaire que les arceaux d'extrémité (non visibles sur la figure 3a) possèdent un profil approprié pour imposer cette nouvelle forme. De même, les poches d'extrémité ont une section interne permettant l'insertion des extrémités de cadre, et notamment des arceaux précités. Par contre, pour des raisons d'esthétique, il est avantageux de prévoir des parois supérieure 94a et inférieure 95a, rectangulaires et planes, sur toute la longueur de l'ossature rigide. Les poches d'extrémité sont constituées par les parois latérales, par exemple 91a (pour l'extrémité droite), supérieure 94a, inférieure 95a, et par un rabat arrière 92a (représenté en traits pointillés). In Figure 3a, there is partially shown a panel la whose main surface 90a of the fabric 9a is of parabolic shape, i.e. having a surface concave. It is necessary that the end hoops (not visible in Figure 3a) have an appropriate profile to impose this new form. Likewise, the pockets end have an internal section allowing insertion frame ends, and in particular the aforementioned arches. On the other hand, for aesthetic reasons, it is advantageous to provide upper 94a and lower 95a walls, rectangular and flat, over the entire length of rigid frame. The end pockets are made up by the side walls, for example 91a (for the end right), upper 94a, lower 95a, and by a flap rear 92a (shown in dotted lines).

La figure 3b illustre une autre forme possible de panneau 1b. La paroi principale avant 90b de la toile 9b est plane. Les arceaux (non visibles) sont bombés vers l'arrière et les parois latérales, par exemple 91a, sont planes et forment des portions d'ellipse. La face principale avant 90b de la toile 9b est plane.Figure 3b illustrates another possible form of panel 1b. The main front wall 90b of the fabric 9b is plane. The hoops (not visible) are curved backwards and the side walls, for example 91a, are flat and form portions of an ellipse. The main face before 90b of the fabric 9b is flat.

La figure 3c illustre une forme de panneau lc, entièrement plat. La paroi principale avant 90c de la toile 9c est plane, ainsi que les parois latérales, par exemple 91c, et les parois supérieure 94c et inférieure 95c.FIG. 3c illustrates a form of panel lc, completely flat. The main front wall 90c of the fabric 9c is planar, as are the side walls, for example 91c, and the upper walls 94c and lower 95c.

L'application préférée du dispositif support de toile conforme à l'invention est la réalisation de panneaux publicitaires, enseignes ou structures murales similaires.The preferred application of the support device canvas according to the invention is the production of panels advertising, signs or similar wall structures.

La figure 4 illustre schématiquement une enseigne murale pour magasin comprenant un dispositif support 1 conforme à l'invention. De façon plus précise, et pour fixer les idées, le panneau 1 formant l'enseigne est du type (forme bombée) décrit en regard des figures 1a à 2f. On a fixé sur le mur M du magasin trois glissières verticales 7 le long desquelles glisse le dispositif proprement dit, comme il a été explicité en regard de la figure 1a, à l'aide des câbles 8 (non représentés). Comme il a été également indiqué, on peut notamment prévoir des sources lumineuses à l'intérieur de la structure du panneau 1 (si la toile est diffusante) pour obtenir un caisson lumineux.Figure 4 schematically illustrates a sign wall for store including a support device 1 according to the invention. More precisely, and to fix the ideas, the panel 1 forming the sign is of the type (convex shape) described with reference to FIGS. 1a to 2f. We have fixed on the wall M of the store three vertical slides 7 along which the device itself slides, as explained with reference to FIG. 1a, using cables 8 (not shown). As it was also indicated, it is possible in particular to provide light sources to inside the structure of panel 1 (if the canvas is diffusante) to obtain a light box.

A la lecture de ce qui précède, on constate aisément que l'invention atteint bien les buts qu'elle s'est fixés.On reading the above, we can easily see that the invention does achieve the goals it has set for itself.

Il doit être clair cependant que l'invention n'est pas limitée aux seuls exemples de réalisations explicitement décrits, notamment en relation avec les figures 1a à 4. It should be clear, however, that the invention is not not limited to only examples of achievements explicitly described, in particular in relation to FIGS. 1a to 4.

En premier lieu, les matériaux utilisés, et notamment la toile de recouvrement, dépendent de l'application spécifique envisagée. Il en est de même des dimensions, de la nature et des sections des tubes et montants composant l'ossature rigide pliable : cadre, etc. Le nombre de glissières de suspension, trois dans les exemples décrits peut être différent, et notamment supérieur pour des panneaux très longs. Dans ce cas, la barre de liaison horizontale comporte des pièces d'accrochage intermédiaires insérées dans les rainures des glissières.First, the materials used, and including the cover fabric, depend on the specific application envisaged. The same is true of dimensions, nature and sections of the tubes and uprights making up the foldable rigid frame: frame, etc. The number of suspension rails, three in examples described may be different, and especially higher for very long panels. In this case, the horizontal link has hooking parts intermediaries inserted in the grooves of the slides.

On peut également, notamment pour des panneaux de très grande longueur, prévoir deux axes de rotation ou plus. A titre d'exemple, dans une variante de réalisation non représentée, on prévoit un cadre central fixe et deux cadres d'extrémité reliés mécaniquement au cadre central par deux axes de rotation.It is also possible, in particular for panels of very long, provide two or more axes of rotation. By way of example, in an alternative embodiment not shown, a fixed central frame and two frames are provided end mechanically connected to the central frame by two axes of rotation.

L'axe de rotation peut égalment ne pas être orthogonal à l'axe longitudinal du panneau.The axis of rotation may also not be orthogonal to the longitudinal axis of the panel.

D'autre part, même si la configuration en housse de la toile de recouvrement est très avantageuse, car de réalisation simple et permettant un temps de dépose et/ou de pose très court, l'invention reste compatible avec d'autres configurations, par exemple des configurations dites "en chaussette", à condition de laisser subsister des orifices pour le passage des organes de blocage et des pièces d'accrochage. A titre d'exemple, on peut recourir à des solutions plus classiques de toiles assujetties sur l'arrière par des tendeurs élastiques.On the other hand, even if the cover configuration of the cover fabric is very advantageous because of simple implementation and allowing time for removal and / or very short exposure, the invention remains compatible with other configurations, for example configurations called "in sock ", provided that holes remain for the passage of locking devices and parts hanging. For example, we can use more conventional solutions of fabrics subject to the rear by elastic tensioners.

Les deux extrémités de cadre, et notamment les arceaux, peuvent être de formes différentes. De même, les cadres eux-mêmes peuvent avoir des formes qui diffèrent de la forme rectangulaire. The two frame ends, and in particular the hoops, can be of different shapes. Likewise, frames themselves can have forms that differ from the rectangular shape.

Enfin, comme il a été indiqué, les notions de droite ou de gauche, ou encore de verticale, sont purement arbitraires. Il est notamment possible, sans sortir du cadre de l'invention, de concevoir un panneau vertical qui se plierait et se déplierait autour d'un axe horizontal.Finally, as indicated, the concepts on the right or left, or vertical, are purely arbitrary. It is notably possible, without going outside the framework of the invention, to design a vertical panel which is would fold and unfold around a horizontal axis.
