Description

La présente invention concerne un dispositif d'affichage sélectif d'informations à vocation publicitaire.The present invention relates to a device for the selective display of information for advertising purposes.

Les évolutions des exigences des exploitants de dispositifs d'affichage ont fait progresser la technique en la matière, et on connaît aujourd'hui divers procédés permettant d'afficher successivement plusieurs informations différentes.Developments in the requirements of operators of display devices have advanced the technique in this area, and we now know various methods for successively displaying several different pieces of information.

Le marché publicitaire actuel, notamment en ce qui concerne les manifestations fortement médiatisées, ne trouve pas dans l'utilisation de tels dispositifs de réponse appropriée à ses besoins. En effet, il est devenu indispensable d'optimiser le rendement d'une campagne d'affichage en disposant de moyens dont la mise en oeuvre est simple, rapide, peu coûteuse, tout en offrant une grande souplesse dans le choix et la modification de l'ordre des passages et des durées d'affichage.The current advertising market, particularly with regard to highly publicized events, does not find in the use of such devices an appropriate response to its needs. Indeed, it has become essential to optimize the performance of a poster campaign by having means whose implementation is simple, quick, inexpensive, while offering great flexibility in the choice and modification of the 'order of passages and display durations.

L'invention s'applique plus particulièrement aux dispositifs d'affichage du type de celui comportant :

  • un magasin de stockage de rouleaux renfermant des affiches support d'informations portées par des bandes souples enroulées sur elles-mêmes,
  • une fenêtre d'affichage permettant de visualiser des informations d'une affiche déroulée devant elle,
  • et un dérouleur permettant de dérouler sélectivement les affiches hors de leur rouleau et derrière la fenêtre d'affichage.
The invention applies more particularly to display devices of the type of that comprising:
  • a roll storage store containing information support posters carried by flexible bands wound on themselves,
  • a display window making it possible to view information from a poster held in front of it,
  • and an unwinder making it possible to selectively unroll the posters out of their roll and behind the display window.

Chacune des affiches est pourvue à une de ses extrémités, d'un moyen de rappel élastique (tel qu'un ressort) permettant d'assurer l'enroulement de l'affiche à l'intérieur de son rouleau en l'absence de toute action extérieure, et à l'autre de ses extrémités, d'un moyen d'extraction extérieur permettant d'annihiler la force opposée du moyen de rappel et de dérouler ladite affiche hors de son rouleau.Each of the posters is provided at one of its ends with an elastic return means (such as a spring) making it possible to wind the poster inside its roller in the absence of any action. external, and at the other of its ends, an external extraction means making it possible to annihilate the opposite force of the return means and unroll said poster out of its roll.

Le brevet français n° 2 647246 propose une solution pour réaliser un tel dispositif d'affichage. A cet effet, ce dispositif comprend :

  • un transporteur (magasin) en boucle fermée entraîné par un moteur et guidé de manière à passer devant une fenêtre d'affichage,
  • une pluralité de supports répartis le long du transporteur et solidaires de celui-ci, chacun de ces supports étant destiné à recevoir une cartouche (rouleau) orientée perpendiculairement à l'axe de défilement du transporteur,
  • des moyens permettant d'assurer une fixation déconnectable desdites cartouches sur lesdits supports,
  • des moyens de rétention (dérouleur) disposés à demeure en un emplacement situé en regard du trajet des moyens d'extraction des affiches, lorsque les cartouches sont entraînées par le transporteur et au voisinage de la fenêtre d'affichage,
  • des moyens de commande du moteur et de sélection des affiches aptes à agir sur les moyens de rétention, en vue de provoquer la rétention des moyens d'extraction d'une affiche sélectionnée lors de son passage en regard dudit emplacement, de manière à provoquer le déroulement de l'affiche dans l'aire de présentation sous l'effet de l'entraînement de la cartouche par le transporteur, et à stopper le transporteur lorsque l'affiche est totalement déroulée.
French Patent No. 2,647,246 proposes a solution for producing such a display device. To this end, this device comprises:
  • a closed loop conveyor (store) driven by a motor and guided so as to pass in front of a display window,
  • a plurality of supports distributed along the conveyor and integral with the latter, each of these supports being intended to receive a cartridge (roller) oriented perpendicular to the axis of travel of the conveyor,
  • means for ensuring a disconnectable attachment of said cartridges on said supports,
  • retention means (unwinder) permanently installed in a location opposite the path of the poster extraction means, when the cartridges are driven by the transporter and in the vicinity of the display window,
  • engine control means and selection of posters capable of acting on the retention means, with a view to causing the retention of the extraction means of a selected poster during its passage opposite said location, so as to cause the unrolling of the poster in the presentation area under the effect of the cartridge being driven by the transporter, and to stop the transporter when the poster is completely unfolded.

Ce dispositif présente l'inconvénient de ne pas permettre l'accès direct à une affiche sans avoir à faire défiler dans un sens où dans l'autre toutes les affiches qui la précèdent sur le transporteur, ceci une fois que l'affiche présentée derrière la fenêtre ait été déconnectée des moyens de rétention afin qu'elle puisse être rangée dans sa cartouche.This device has the drawback of not allowing direct access to a poster without having to scroll in a direction where in the other all the posters which precede it on the transporter, this once the poster presented behind the window has been disconnected from the retention means so that it can be stored in its cartridge.

Un dispositif d'affichage à deux magasins de stockage et répondant aux définitions du préambule de la revendication 1 est décrit par US-A-2 195 249.A display device with two storage magazines and meeting the definitions of the preamble of claim 1 is described by US-A-2 195 249.

Le problème technique à résoudre par l'objet de la présente invention, est donc de proposer un dispositif d'affichage simple de mise en oeuvre, peu coûteux, permettant de définir et de modifier simplement l'ordre et la durée de présentation de chaque affiche et de réduire au maximum les temps morts entre les opérations de désaffichage et d'affichage.The technical problem to be solved by the object of the present invention is therefore to propose a display device which is simple to implement, inexpensive, making it possible to define and modify simply the order and the duration of presentation of each poster. and to minimize the downtime between display and display operations.

Pour répondre à ce problème, le concept fondamental de l'invention consiste à utiliser un dispositif d'affichage du type de celui rappelé ci-dessus et se composant d'un bâti autoporteur comportant deux magasins de stockage de rouleaux disposés à ses extrêmes, derrière la fenêtre d'affichage et sur la hauteur de cette dernière, de telle sorte que le susdit dérouleur puisse assurer le déroulement de l'affiche d'un magasin derrière la fenêtre en même temps que l'enroulement de l'affiche de l'autre magasin venant d'être présentée, et vice-versa.To respond to this problem, the fundamental concept of the invention consists in using a display device of the type recalled above and consisting of a self-supporting frame comprising two roll storage magazines arranged at its ends, behind the display window and on the height of the latter, so that the above unwinder can ensure the unfolding of the poster of a store behind the window at the same time as the winding of the poster of the other store just presented, and vice versa.

Un tel dispositif d'affichage offre de nombreux avantages car il permet de réduire au minimum les temps morts entre les opérations de désaffichage et d'affichage, puisque :

  • pendant le temps de visualisation d'une affiche d'un magasin derrière la fenêtre d'affichage, une autre affiche est sélectionnée dans l'autre magasin,
  • le déroulement d'une affiche d'un magasin s'opère en même temps que l'enroulement d'une affiche venant d'être présentée par l'autre magasin,
Such a display device offers many advantages because it allows minimize downtime between display and display operations, since:
  • while viewing a poster of a store behind the display window, another poster is selected in the other store,
  • the unfolding of a poster of a store takes place at the same time as the winding of a poster that has just been presented by the other store,

En outre, il autorise un ordre non établi de défilement des affiches.In addition, it authorizes an undefined order of scrolling of the posters.

Selon une caractéristique particulièrement avantageuse de l'invention, le susdit dérouleur évolue d'une extrémité du bâti autoporteur où est installé un magasin (dit premier magasin) vers son extrémité opposée où est installé l'autre magasin (dit deuxième magasin). Ce dérouleur est pourvu d'un dispositif d'accrochage du moyen d'extraction des affiches hors de leur rouleau, de telle sorte que, lorsque le dérouleur est mis en mouvement du premier magasin vers le deuxième magasin, il assure, derrière la fenêtre d'affichage, l'enroulement de l'affiche du deuxième magasin en même temps que le déroulement de l'affiche du premier magasin, et, lorsque le dérouleur est mis en mouvement inverse, il assure l'enroulement d'une affiche du premier magasin en même temps que le déroulement d'une affiche du deuxième magasin.According to a particularly advantageous characteristic of the invention, the aforementioned unwinder evolves from one end of the self-supporting frame where a store is installed (said first store) to its opposite end where the other store is installed (said second store). This unwinder is provided with a device for hooking the means for extracting the posters from their roll, so that, when the unwinder is moved from the first magazine to the second magazine, it ensures, behind the window d display, the winding of the poster of the second store at the same time as the unfolding of the poster of the first store, and, when the unwinder is set in reverse movement, it ensures the winding of a poster of the first store at the same time as the unfolding of a poster from the second store.

Par rapport aux dispositifs antérieurs, le déroulement est dynamique puisque c'est lui qui vient en regard des moyens d'extraction d'une affiche sélectionnée de l'un où l'autre des magasins et qui assure le déroulement et la présentation d'une affiche derrière la fenêtre.Compared to previous devices, the process is dynamic since it is it which comes next to the means of extracting a selected poster from one or the other of the stores and which ensures the process and presentation of a poster behind the window.

Selon la disposition principale de l'invention, le dérouleur guide également l'enroulement de l'affiche sur elle-même à l'intérieur de son rouleau, et ce en même temps que le déroulement de l'affiche suivante.According to the main arrangement of the invention, the unwinder also guides the winding of the poster on itself inside its roller, and this at the same time as the unfolding of the following poster.

Le dispositif de l'invention présente un avantage notable dans la mesure où les magasins de stockage des rouleaux contenant les affiches et le dérouleur sont dynamiques. Une interaction judicieusement programmée entre eux par une électronique d'asservissement des moteurs d'entraînement permettra de réduire au minimum les temps morts.The device of the invention has a notable advantage in that the storage stores for the rolls containing the posters and the unwinder are dynamic. A judiciously programmed interaction between them by electronic servo drive motors will minimize downtime.

Selon une forme de réalisation préférentielle de l'invention permettant d'optimiser au maximum la surface d'affichage du dispositif de l'invention, il est possible de concevoir un dispositif comportant deux fenêtres d'affichage et deux dérouleurs disposés de part et d'autre des deux magasins. Cette application sera notamment utile lorsque le dispositif d'affichage sera installé de manière à ce que les deux fenêtres opposées soient exposées à la vue du public.According to a preferred embodiment of the invention making it possible to optimize the display surface of the device of the invention as much as possible, it is possible to design a device comprising two display windows and two unwinders arranged on either side other of the two stores. This application will be particularly useful when the display device is installed so that the two opposite windows are exposed to public view.

L'invention venant d'être évoquée ci-dessus dans sa forme la plus élémentaire, d'autres caractéristiques et d'autres avantages ressortiront plus clairement à la lecture de la description qui suit donnant, à titre d'exemple non limitatif, un mode de réalisation d'un dispositif d'affichage illustrant les concepts fondamentaux de l'invention.The invention having just been mentioned above in its most basic form, other characteristics and other advantages will emerge more clearly on reading the description which follows giving, by way of nonlimiting example, a mode production of a display device illustrating the fundamental concepts of the invention.

This elastic return may be constituted by a coil type spring wedged between the roller housing and an axis mounted in free rotation on which is fixed one end of said poster.

L'autre extrémité de l'affiche 21 la, située en dehors du boîtier du rouleau 210a, est préformée d'un ourlet, dans lequel est enfilée une tringle 212a faisant office de moyen d'extraction permettant , à l'aide d'un moyen d'accrochage approprié, d'annihiler la force opposée du moyen de rappel du ressort et de dérouler l'affiche 21 la hors de son rouleau 210a. Ainsi, lorsqu'on agit sur la tringle 21 la dans le sens indiqué par la flèche D, l'affiche 21 la se déroule hors du rouleau 210a tout en restant tendue par la tension opposée exercée par la force de rappel E du ressort. Lorsque l'action de l'effort d'extraction est annulée, l'effort de rappel du ressort assure l'enroulement de l'affiche 21 la à l'intérieur du rouleau 210a comme montré par la flèche E.The other end of the poster 21a1, situated outside the housing of the roller 210a, is preformed with a hem, in which a rod 212a is threaded serving as extraction means allowing, using a appropriate attachment means, to annihilate the opposite force of the spring return means and to unroll the poster 21 out of its roll 210a. Thus, when acting on the rod 21a in the direction indicated by the arrow D, the poster 21a takes place outside of the roller 210a while remaining taut by the opposite tension exerted by the return force E of the spring. When the action of the extraction force is canceled, the spring return force ensures the winding of the poster 21a inside the roller 210a as shown by the arrow E.

Pour assurer un stockage dynamique des affiches 211a, 211b, les magasins 200a et 200b sont constitués chacun par une chaîne sans fin 220a, 220b, entraînée chacune autour de deux cylindres dont un au moins est moteur. Ces chaînes sans fin 220a et 220b ont pour objet de recevoir (de préférence de manière amovible) les rouleaux 210a et 210b renfermant les affiches 211a et 211b. L'entraînement rotatif des chaînes sans fin autour de leurs cylindres de renvoi a pour objet de pouvoir présenter devant le dérouleur un rouleau 210, quel que soit son positionnement dans son magasin.To ensure dynamic storage of the posters 211a, 211b, the stores 200a and 200b each consist of an endless chain 220a, 220b, each driven around two cylinders of which at least one is a motor. These endless chains 220a and 220b are intended to receive (preferably removably) the rollers 210a and 210b containing the posters 211a and 211b. The purpose of the rotary drive of the endless chains around their return cylinders is to be able to present a roller 210 in front of the unwinder, whatever its position in its magazine.

Le mode de réalisation des magasins 200a et 200b est donné à titre d'exemple préférentiel de réalisation car le renvoi des chaînes sans fin autour de leurs cylindres, permet de disposer de toute la hauteur utile dégagée derrière la fenêtre d'affichage 300, tout en réduisant l'épaisseur du bâti imposée par le diamètre desdits cylindres. Lorsque le nombre d'affiches est moins important, il sera possible de remplacer les magasins 200a et 200b par deux tambours ou barillets recevant périphériquement les rouleaux 210a au 210b.The embodiment of stores 200a and 200b is given as a preferred embodiment because the return of the endless chains around their cylinders makes it possible to have all the useful height released behind the display window 300, while reducing the thickness of the frame imposed by the diameter of said cylinders. When the number of posters is lower, it will be possible to replace the magazines 200a and 200b by two drums or barrels receiving peripherally the rollers 210a to 210b.

Les magasins 200a et 200b définissant ainsi des ensembles indépendants modulaires, peuvent aussi être interchangés rapidement dans le dispositif d'affichage de l'invention. Pour ce faire, les flasques entretoisées 110 et 120 constituant le bâti autoporteur 100 du dispositif sont ménagés d'encoches 111 et 121 débouchant vers l'arrière du bâti et permettant la pose ou la dépose rapide d'un magasin 200a ou 200b.The magazines 200a and 200b thus defining independent modular assemblies, can also be quickly interchanged in the display device of the invention. To do this, the braced flanges 110 and 120 constituting the self-supporting frame 100 of the device are provided with notches 111 and 121 opening towards the rear of the frame and allowing the rapid installation or removal of a magazine 200a or 200b.

La fenêtre d'affichage 300 permettant de visualiser les informations de l'affiche 211a ou 211b déroulée derrière elle, est également fixée de manière interchangeable sur les flasques 110, 120 du bâti 100, sur la quasi totalité de la hauteur de ce dernier, délimitant la hauteur utile d'exploitation. Dans des conditions particulières d'application notamment pour éviter les problèmes de réflexion de lumière incidente, la fenêtre d'affichage 300 pourra être dépourvue de tout vitrage de protection.The display window 300 making it possible to view the information of the poster 211a or 211b unrolled behind it, is also fixed interchangeably on the flanges 110, 120 of the frame 100, over almost the entire height of the latter, delimiting the useful operating height. Under particular conditions of application, in particular to avoid problems of reflection of incident light, the display window 300 may be devoid of any protective glazing.

Selon un mode de réalisation préférentielle de l'invention, le dispositif d'affichage comporte un caisson lumineux intégré 500 venant s'insérer dans l'épaisseur du dérouleur 400 dans l'espace dégagé entre les cylindres de renvoi 420a, 420b. Ce caisson lumineux 500, placé à distance de la fenêtre 300 pour dégager un passage aux affiches 211a, 211b se présentant, permet d'éclairer ces dernières à l'arrière et de conforter éventuellement le maintien de celles-ci.According to a preferred embodiment of the invention, the display device comprises an integrated light box 500 which is inserted into the thickness of the unwinder 400 in the space cleared between the return cylinders 420a, 420b. This light box 500, placed at a distance from the window 300 to clear a passage to the posters 211a, 211b which presents themselves, makes it possible to illuminate the latter at the rear and possibly to reinforce their maintenance.

Le dérouleur 400 est, quant à lui, disposé entre la fenêtre d'affichage 300 et les deux magasins 200a et 200b. Il est constitué d'une bande sans fin 410 entraînée autour de deux cylindres de renvoi 420a et 420b, calés entre les deux flasques 110 et 120 du bâti 100 en partie haute et basse de ce dernier. Un moteur 430 assure l'entraînement de la bande sans fin 410 autour desdits cylindres 420a, 420b. Selon l'invention, la bande sans fin 410 est aménagée de deux crochets 411a, 411b disposés en vis à vis et faisant office de moyens d'accrochage des moyens d'extraction des affiches 211a ou 211b. Ces crochets 41 la, 411b sont, d'une part, suffisamment espacés l'un de l'autre, et, d'autre part, suffisamment ouverts pour autoriser l'accrochage ou le décrochage de la tringle formant les susdits moyens d'extraction 212a et 212b des affiches 21 la, 211b.The unwinder 400 is, in turn, disposed between the display window 300 and the two stores 200a and 200b. It consists of an endless belt 410 driven around two return cylinders 420a and 420b, wedged between the two flanges 110 and 120 of the frame 100 in the upper and lower part of the latter. A motor 430 drives the endless belt 410 around said cylinders 420a, 420b. According to the invention, the endless belt 410 is provided with two hooks 411a, 411b arranged opposite and acting as attachment means for the extraction means of posters 211a or 211b. These hooks 41a, 411b are, on the one hand, sufficiently spaced from one another, and, on the other hand, sufficiently open to allow the attachment or detachment of the rod forming the aforesaid extraction means 212a and 212b of posters 21a1, 211b.

Le nombre de paires de crochets 411a, 411b répartis sur la largeur de la bande sans fin 410, sera fonction de la largeur des affiches 211a ou 211b. A cet effet, il sera possible de positionner des paires de crochets aux deux extrémités de la tringle 21 la 212b dépassant éventuellement des affiches 21 la ou 2116 et/ou dans des oeillets pratiqués sur la longueur de l'ourlet formé aux extrémités des affiches 211a, 211b pour recevoir lesdites tringles.The number of pairs of hooks 411a, 411b distributed over the width of the endless strip 410 will depend on the width of the posters 211a or 211b. For this purpose, it will be possible to position pairs of hooks at the two ends of the rod 21 the 212b possibly protruding from the posters 21 la or 2116 and / or in eyelets formed along the length of the hem formed at the ends of the posters 211a , 211b to receive said rods.

Selon un mode de réalisation préférentielle de l'invention, la bande sans fin 410 du dérouleur 400 est équipée à ses deux extrémités, en amont des cylindres de renvoi 420a, 420b de deux moyens de guidage de bande 440a, 440b, formés chacun de deux galets disposés en S, les deux moyens de guidage étant destinés à définir aux points haut et bas du dérouleur, une portion rectiligne de la bande 410 au-delà de la portion courbe des chaînes sans fin des susdits magasins 200a et 200b.According to a preferred embodiment of the invention, the endless belt 410 of the unwinder 400 is equipped at its two ends, upstream of the return cylinders 420a, 420b with two belt guide means 440a, 440b, each formed of two rollers arranged in S, the two guide means being intended to define at the top and bottom points of the unwinder, a rectilinear portion of the strip 410 beyond the curved portion of the endless chains of the above stores 200a and 200b.

Les dispositifs de guidage 440a, 440b ont notamment pour avantage de donner un angle d'inclinaison aux crochets 411a, 411b améliorant l'accrochage et/ou le décrochage des tringles 212a, 212b. Un autre avantage des moyens de guidage 440a, 440b est de pouvoir faire défiler les affiches sur toute la hauteur de la fenêtre 300 et de garer les crochets 411a, 411b hors de la trajectoire des rouleaux 210a, 210b, et éviter toute interférence avec ceux-ci. En outre, ces moyens de guidage sont aussi utilisés comme détecteurs de fin de course du défilement de la bande sans fin 410.The guide devices 440a, 440b have the particular advantage of giving an angle of inclination to the hooks 411a, 411b improving the attachment and / or detachment of the rods 212a, 212b. Another advantage of the guide means 440a, 440b is to be able to scroll the posters over the entire height of the window 300 and to park the hooks 411a, 411b outside the path of the rollers 210a, 210b, and avoid any interference with them. this. In addition, these guide means are also used as end of travel detectors for the running of the endless belt 410.
