Definitions
- the invention relates to a display device taut canvas and find a particular application in the field of the sign, especially outdoors.
- Such devices generally take the form of a box, obtained from a support structure, or of several support structures assembled to each other. Each structure is usually a mechanically welded, more or less complex to manufacture.
- the tensioning of the fabric on the frame of the device is obtained by means of a tensioning system of the fabric.
- the screw tensioning systems comprise on the periphery of the box a plurality of screw units, for example spaced apart from each other every 20 cm, each connecting the fabric and the structure.
- the tensioning of the fabric is thus obtained by screwing each of the screwing units with a tool, one after the other, on the periphery of the device.
- the ring tensioning systems allow the tensioning of the fabric, by pinch effect of the fabric between a peripheral groove of the structure and several profiles ("the rods") forcibly fitted into said peripheral groove.
- the tension is forced by inserting the rods in the peripheral groove, usually by mallet.
- the spring tensioning systems comprise springs, distributed over the periphery of the box of the display device, each connecting the fabric to the structure of the box.

- Each spring element is a coil spring, helical, terminated at both ends by two hooks, directed in the same direction, one engaging with the structure, the other through an eyelet of the fabric.
- each spring element also comprises a loop intended to be traversed by a tool (ie a screwdriver) to facilitate the tensioning of the spring element by lever effect. In such a device the tensioning of the fabric is carried out, for each spring, in a single step of tensioning, which can prove particularly tedious when the fabric is free and undergoes the action of the wind.
- Another spring tension system known to the inventor comprises spring elements each connecting the fabric to the structure.
- the attachment of each spring element on the structure is obtained by means of a rack rigidly secured to the sidewall of the support structure and a corresponding notched piece integral with one of the ends of the spring element. notched piece comprising a plurality of teeth adapted to engage in locking with said rack to tension the spring element to the desired tension.
- This system requires, for each spring element, the presence of a rack, machined metal part, rigidly secured to the structure and a part notched, machined metal part corresponding to one end of the spring element, encumbering the cost of this device. Furthermore, with such a system it is not possible to choose the positioning and distribution of the spring elements on the periphery of the display device because they must imperatively be positioned respectively opposite the racks, local, distributed and discarded spaced apart from one another on the periphery of the display box.

- the first step of tensioning the fabric at said first tension value allows the easy and fast installation of the fabric on the structure, to subtract the fabric to the possible influence of wind.
- this first voltage value may not be sufficient to remove all the folds on the canvas, which may degrade the display.
- the operator can then stretch more strongly each of the spring elements, and thus stretch the fabric more strongly to said second voltage value, in order to remove the last folds on the fabric.
- attachment wings which each extend continuously along the length of the sidewall, and to the ring which also extends continuously over this length, it is possible to hook each of the spring elements in different positions along the length of the sidewall.
- the ring received in the hem also allows a uniform distribution of the tensile force on the periphery of the fabric, and this in contrast to local fasteners (ie eyelets) which distribute the efforts in a discontinuous manner, thus promoting the appearance of folds on the canvas.
- each spring element is a helical pull spring terminated at both ends by two hooks, the two hooks at the ends of the spring being advantageously directed in two opposite directions.
- One of the hooks then makes it possible to crochet the fabric towards the outside, the other hook being turned inwards to engage with one of the two fastening wings.
- each of said support edges, and said two corresponding attachment wings to said support edge may be constituted by a metal section, in one piece.
- said at least two sidewalls each consist of said section which has an elongate section comprising a first part of length, straight, tubular, and a second part of length, tubular, inclined with respect to said first portion of length, directed towards the outside of the box.

Description
L'invention concerne un dispositif d'affichage à toile tendue et trouvera une application particulière dans le domaine de l'enseigne, en particulier en extérieur.The invention relates to a display device taut canvas and find a particular application in the field of the sign, especially outdoors.
L'homme de l'art du domaine de l'enseigne connaît les dispositifs d'affichage à toile tendue. L'information à afficher y est présentée sur une toile, souple, qui est tendue fortement sur un cadre pour obtenir un affichage parfait, sans pli. Le moindre pli disgracieux est accentué par l'éclairage, interne au dispositif, lorsque le dispositif en est équipé.Those skilled in the art of the field of the sign knows the display devices stretched canvas. The information to display is presented on a canvas, flexible, which is stretched strongly on a frame to obtain a perfect display, without crease. The least unsightly fold is accentuated by the illumination, internal to the device, when the device is equipped.
De tels dispositifs prennent généralement la forme d'un caisson, obtenu à partir d'une structure support, ou encore de plusieurs structures supports assemblées les unes aux autres. Chaque structure est généralement un mécano-soudée, plus ou moins complexe à fabriquer.Such devices generally take the form of a box, obtained from a support structure, or of several support structures assembled to each other. Each structure is usually a mechanically welded, more or less complex to manufacture.
La mise en tension de la toile sur le cadre du dispositif est obtenue au moyen d'un système de mise en tension de la toile.The tensioning of the fabric on the frame of the device is obtained by means of a tensioning system of the fabric.
Bien souvent ces dispositifs d'affichage sont installés, en extérieur, et en hauteur, nécessitant pour le poseur l'utilisation d'une nacelle élévatrice. Dans le cas de grandes enseignes, le caisson résulte bien souvent de l'assemblage de plusieurs structures mécano soudée, assemblées les unes aux autres, en hauteur. La mise en place de la toile et sa mise en tension sur le dispositif sont effectuées également en extérieur, en hauteur, dans des conditions plus ou moins aisées en fonction des conditions météorologiques. Ces opérations peuvent ainsi être particulièrement difficiles lors de vents plus ou moins forts, la toile réagissant alors comme une voile.Often these display devices are installed outdoors and at height, requiring the installer to use an aerial platform. In the case of large signs, the box often results from the assembly of several welded structures, assembled to each other, in height. The setting up of the fabric and its tensioning on the device are also performed outdoors, in height, in more or less easy conditions depending on the weather conditions. These operations can be particularly difficult during more or less strong winds, the web then reacting like a sail.
Les systèmes de mise en tension de la toile, connus de l'homme de l'art, exploités aujourd'hui, sont essentiellement de trois types, à savoir :
- les systèmes de mise en tension à vis,
- les systèmes de mise en tension à jonc,
- les systèmes de mise en tension à ressorts.
- screw tensioning systems,
- tensioning systems with rushes,
- tensioning systems with springs.
Les systèmes de mise en tension à vis comprennent sur le pourtour du caisson une pluralité d'unités de vissage, par exemple écartées entre elles tous les 20 cm, reliant chacune la toile et la structure. La mise en tension de la toile est donc obtenue par vissage de chacune des unités de vissage, avec un outil, les unes après les autres, sur la périphérie du dispositif. Ces opérations de vissage successives s'avèrent particulièrement fastidieuses et chronophages pour de grandes enseignes.The screw tensioning systems comprise on the periphery of the box a plurality of screw units, for example spaced apart from each other every 20 cm, each connecting the fabric and the structure. The tensioning of the fabric is thus obtained by screwing each of the screwing units with a tool, one after the other, on the periphery of the device. These successive screwing operations are particularly tedious and time-consuming for large brands.
Un autre défaut important de ce type de système est que la toile est tendue à une tension fixe. En fonction des conditions de l'environnement extérieure, et en particulier des variations d'humidité, la toile peut se contracter puis se détendre, engendrant l'apparition de plis disgracieux sur la zone d'affichage.Another important defect of this type of system is that the fabric is stretched at a fixed tension. Depending on the conditions of the outdoor environment, and in particular moisture variations, the fabric can contract and relax, causing unsightly folds on the display area.
Les systèmes de mise en tension à jonc permettent la mise en tension de la toile, par effet de pincement de la toile entre une rainure périphérique de la structure et plusieurs profilés (« les joncs ») emboités à force dans ladite rainure périphérique. La mise en tension s'effectue à force en insérant les joncs dans la rainure périphérique, usuellement à coup de maillet.The ring tensioning systems allow the tensioning of the fabric, by pinch effect of the fabric between a peripheral groove of the structure and several profiles ("the rods") forcibly fitted into said peripheral groove. The tension is forced by inserting the rods in the peripheral groove, usually by mallet.
Les documents
Les systèmes de mise en tension à ressorts comprennent des ressorts, répartis sur la périphérie du caisson du dispositif d'affichage, reliant chacun la toile à la structure du caisson. Le document
Un autre système de tension, à ressorts, connu de l'inventeur, comprend des éléments ressorts reliant chacun la toile à la structure. L'accrochage de chaque élément ressort sur la structure est obtenu au moyen d'une crémaillère, rigidement solidaire du flanc de la structure support et d'une pièce crantée, correspondante, solidaire de l'une des extrémités de l'élément ressort, ladite pièce crantée comprenant plusieurs dents apte à engager au blocage avec ladite crémaillère pour tendre l'élément ressort à la tension voulue.Another spring tension system known to the inventor comprises spring elements each connecting the fabric to the structure. The attachment of each spring element on the structure is obtained by means of a rack rigidly secured to the sidewall of the support structure and a corresponding notched piece integral with one of the ends of the spring element. notched piece comprising a plurality of teeth adapted to engage in locking with said rack to tension the spring element to the desired tension.
Ce Système nécessite, pour chaque élément ressort, la présence d'une crémaillère, pièce métallique usinée, rigidement solidaire de la structure et d'une pièce crantée, pièce métallique usinée, correspondante à l'une des extrémités de l'élément ressort, grevant le coût de ce dispositif. Par ailleurs, avec un tel système il n'est pas possible de choisir le positionnement et la distribution des éléments ressorts sur la périphérie du dispositif d'affichage car ceux-ci doivent impérativement être positionnés respectivement en regard des crémaillères, locales, réparties et écartées distantes, les unes des autres, sur la périphérie du caisson du dispositif d'affichage.This system requires, for each spring element, the presence of a rack, machined metal part, rigidly secured to the structure and a part notched, machined metal part corresponding to one end of the spring element, encumbering the cost of this device. Furthermore, with such a system it is not possible to choose the positioning and distribution of the spring elements on the periphery of the display device because they must imperatively be positioned respectively opposite the racks, local, distributed and discarded spaced apart from one another on the periphery of the display box.
Le but de la présente invention est de pallier les inconvénients précités en proposant un dispositif d'affichage à toile tendue, équipé d'un système de mise en tension du type à ressort, facilitant la pose et la mise en tension de la toile.The object of the present invention is to overcome the aforementioned drawbacks by providing a display device with stretched fabric, equipped with a tensioning system of the spring type, facilitating the installation and tensioning of the fabric.
Plus particulièrement, un but de la présente invention est de proposer un tel dispositif d'affichage dont la mise en place et la mise en tension de la toile peuvent être réalisées sans difficulté, même dans le cas de vent.More particularly, an object of the present invention is to provide such a display device, the establishment and tensioning of the fabric can be performed without difficulty, even in the case of wind.
Un autre but de la présente invention est de proposer un tel dispositif d'affichage dont les positionnements et la distribution des éléments ressorts sur la périphérie du dispositif peuvent être choisis, selon les souhaits du poseur, notamment en fonction des conditions de pose.Another object of the present invention is to provide such a display device whose positioning and the distribution of the spring elements on the periphery of the device can be chosen, according to the wishes of the installer, in particular according to the laying conditions.
Un autre but de la présente invention est de proposer un tel dispositif d'affichage de construction aisée, et à moindre coût.Another object of the present invention is to provide such a display device of easy construction, and at a lower cost.
Un autre but de la présente invention est de proposer un tel dispositif d'affichage facilitant la réalisation de grandes enseignes.Another object of the present invention is to provide such a display device facilitating the production of large signs.
Un autre but de la présente invention est de proposer un tel dispositif d'affichage facilitant les opérations de maintenance (i.e. changement éclairage interne), en particulier de retrait de la toile.Another object of the present invention is to provide such a display device facilitating the maintenance operations (i.e. internal lighting change), in particular removal of the fabric.
Un autre but de la présente invention est de proposer un tel dispositif dont la structure est de conception simplifiée et peut être assemblée au moyen d'organes de fixations telles que des vis, et notamment sans soudure.Another object of the present invention is to provide such a device whose structure is of simplified design and can be assembled by means of fasteners such as screws, and in particular without welding.
D'autre buts et avantages de l'invention apparaîtront au cours de la description qui va suivre qui n'est donnée qu'à titre indicatif et qui n'a pas pour but de la limiter.Other objects and advantages of the invention will become apparent from the following description which is given for information only and which is not intended to limit it.
Aussi l'invention concerne un dispositif d'affichage à toile tendue, comprenant :
- une toile destinée pour l'affichage,
- au moins une structure formant un caisson, ladite structure comprenant au moins deux flancs, ainsi qu'au moins deux bords d'appui appartenant respectivement auxdits au moins deux flancs, entre lesquels est destinée à être tendue ladite toile,
- un système de mise en tension de ladite toile comprenant des éléments ressorts destinés à relier chacun, en tension, la toile et ladite structure, l'une des extrémités dudit élément ressort crochetant la toile, l'autre extrémité dudit élément ressort crochetant la structure.
- a canvas intended for display,
- at least one structure forming a box, said structure comprising at least two sidewalls, and at least two support edges respectively belonging to said at least two sidewalls, between which said fabric is intended to be stretched,
- a tensioning system of said fabric comprising spring elements intended to each connect, in tension, the fabric and said structure, one end of said spring element hooking the fabric, the other end of said spring element hooking the structure.
Selon le dispositif conforme à l'invention :
- lesdits au moins deux flancs de la structure présentent chacun deux ailes d'accrochage dudit système de mise en tension de la toile, lesdites deux ailes d'accrochage étant parallèles entre elles, apte à coopérer chacune à l'accrochage avec l'une des extrémités d'un élément ressort, lesdites deux ailes d'accrochage étant agencées en deux positions distincts sur la largeur du flanc pour autoriser le réglage de la tension de chacun desdits éléments ressorts suivant deux valeurs de tension distinctes,
- said at least two flanks of the structure each have two attachment wings of said tensioning system of the fabric, said two gripping wings being parallel to each other, each capable of cooperating with one of the ends a spring element, said two attachment wings being arranged in two distinct positions on the width of the sidewall to allow the adjustment of the tension of each of said spring elements according to two distinct tension values,
Le dispositif conforme à l'invention permet avantageusement la mise en oeuvre d'un procédé pour la mise en tension de la toile dans lequel :
- on tend la toile à une première valeur de tension en crochetant chaque élément ressort à l'une des ses extrémités à ladite toile et à l'autre extrémité à l'une des deux ailes d'accrochage,
- on tend la toile à une deuxième valeur de tension, supérieure à ladite première valeur, en crochetant l'autre extrémité de chacun des éléments ressorts sur l'autre des deux ailes d'accrochage.
- the fabric is stretched at a first tension value by hooking each spring element at one of its ends to said fabric and at the other end to one of the two attachment wings,
- the fabric is stretched to a second tension value, greater than said first value, by hooking the other end of each of the spring elements on the other of the two attachment wings.
La première étape de mise en tension de la toile à ladite première valeur de tension permet la mise en place aisée et rapide de la toile sur la structure, permettant de soustraire la toile à l'éventuelle influence du vent.The first step of tensioning the fabric at said first tension value allows the easy and fast installation of the fabric on the structure, to subtract the fabric to the possible influence of wind.
Toutefois cette première valeur de tension peut ne pas être suffisante pour supprimer l'ensemble des plis sur la toile, susceptibles de dégrader l'affichage.However, this first voltage value may not be sufficient to remove all the folds on the canvas, which may degrade the display.
Dans un deuxième temps l'opérateur peut alors étirer plus fortement chacun des éléments ressorts, et ainsi tendre plus fortement la toile à ladite deuxième valeur de tension, afin de supprimer les derniers plis sur la toile.In a second step the operator can then stretch more strongly each of the spring elements, and thus stretch the fabric more strongly to said second voltage value, in order to remove the last folds on the fabric.
Grâce auxdites ailes d'accrochage qui s'étendent chacune continûment sur la longueur du flanc, ainsi qu'au jonc qui s'étend également continûment sur cette longueur, il est possible de crocheter chacun des éléments ressorts en différentes positions sur la longueur du flanc.Thanks to said attachment wings which each extend continuously along the length of the sidewall, and to the ring which also extends continuously over this length, it is possible to hook each of the spring elements in different positions along the length of the sidewall. .
Le jonc reçu dans l'ourlet permet par ailleurs une répartition uniforme de l'effort de traction sur la périphérie de la toile, et ce contrairement à des fixations locales, (i.e. des oeillets) qui répartiraient les efforts de manière discontinue, favorisant ainsi l'apparition de plis sur la toile.The ring received in the hem also allows a uniform distribution of the tensile force on the periphery of the fabric, and this in contrast to local fasteners (ie eyelets) which distribute the efforts in a discontinuous manner, thus promoting the appearance of folds on the canvas.
Selon un mode de réalisation facilitant les opérations d'accrochage, chaque élément ressort est un ressort hélicoïdale de traction terminé à ses deux extrémités par deux crochets, les deux crochets aux extrémités du ressort étant avantageusement dirigés suivant deux sens opposés. L'un des crochets permet alors de crocheter la toile vers l'extérieur, l'autre crochet étant tourné vers l'intérieur pour engager avec l'une des deux ailes d'accrochage.According to an embodiment facilitating the attachment operations, each spring element is a helical pull spring terminated at both ends by two hooks, the two hooks at the ends of the spring being advantageously directed in two opposite directions. One of the hooks then makes it possible to crochet the fabric towards the outside, the other hook being turned inwards to engage with one of the two fastening wings.
Selon un mode de réalisation simplifiant la construction du dispositif chacun desdits bords d'appui, ainsi que lesdites deux ailes d'accrochage correspondantes audit bord d'appui peuvent être constitués par un profilé métallique, d'un seul tenant.According to an embodiment simplifying the construction of the device each of said support edges, and said two corresponding attachment wings to said support edge may be constituted by a metal section, in one piece.
