Abstract

The invention concerns a scrolling poster display device, comprising two parallel rolls, a poster strip wound on the rolls and a support device for supporting the rear side of the poster strip between the rolls. The support device comprises an air chamber delimited by a peripheral frame and a base offset rearward, and an air blowing device generates an excess pressure of air in the air chamber.

Description

La présente invention est relative aux dispositifs d'affichage à affiches défilantes.The present invention relates to scrolling poster display devices.

Plus particulièrement, l'invention concerne un dispositif d'affichage à affiches défilantes, comportant :

  • au moins deux rouleaux parallèles,
  • une bande d'affiches enroulée sur les rouleaux, ladite bande d'affiches comportant une face avant visible du public et une face arrière opposée à la face avant,
  • au moins un moteur pour entraîner les rouleaux,
  • et un dispositif de support fixe adapté pour conformer la face arrière de la bande d'affiches entre lesdits rouleaux.
More particularly, the invention relates to a display device with moving posters, comprising:
  • at least two parallel rollers,
  • a band of posters wound on the rollers, said band of posters having a visible front face of the public and a rear face opposite to the front face,
  • at least one motor for driving the rollers,
  • and a fixed support device adapted to conform the back side of the poster band between said rollers.

Le document US-A-5 174 055 décrit un dispositif d'affichage de ce type, dans lequel la face arrière de la bande d'affiche est en appui sur une plaque de support pleine qui s'étend sur toute la surface de cette affiche et permet notamment de donner une forme galbée à l'affiche. Ce dispositif d'affichage présente notamment les inconvénients suivantes :

  • le frottement des affiches ou de leur bande de support sur la plaque d'appui peut entraîner une usure et/ou une salissure des affiches ou de leur bande support,
  • ce frottement génère de l'électricité statique qui fait coller les affiches à la plaque d'appui, ce qui gêne le bon défilement des affiches et peut même entraîner leur déchirement.
The document US-A-5,174,055 describes a display device of this type, in which the rear face of the poster band is resting on a solid support plate which extends over the entire surface of this poster and allows in particular to give a curved shape to poster. This display device has the following drawbacks:
  • the friction of the posters or their support strip on the backing plate may lead to wear and / or staining of the posters or their support tape,
  • this friction generates static electricity that makes posters stick to the backing plate, which hinders the proper scrolling of the posters and may even cause them to tear.

L'invention a notamment pour but de pallier ces inconvénients.The invention is intended to overcome these disadvantages.

A cet effet, selon l'invention, un dispositif d'affichage du genre en question est caractérisé en ce que le dispositif de support comporte une chambre à air délimitée par un cadre périphérique adjacent à la face arrière de la bande d'affiches et un fond décalé vers l'arrière par rapport au cadre, ledit dispositif de support ne comportant aucun élément voisin de la face arrière de la bande d'affiches à l'intérieur du cadre,
et en ce qu'il comporte en outre au moins un dispositif de soufflage d'air adapté pour créer une surpression d'air dans la chambre à air, l'air injecté dans la chambre à air fuyant vers l'extérieur en formant une lame d'air à l'interface entre le cadre et la face arrière de la bande d'affiches.For this purpose, according to the invention, a display device of the kind in question is characterized in that the support device comprises an air chamber delimited by a peripheral frame adjacent to the rear face of the poster band and a background shifted to the rear relative to the frame, said support device having no adjacent element of the rear face of the poster band inside the frame,
and in that it further comprises at least one air blowing device adapted to create an air overpressure in the air chamber, the air injected into the air chamber leaking outwardly forming a blade air at the interface between the frame and the back of the poster band.

Grâce à ces dispositions, on fait gonfler la bande d'affiche sous l'effet du soufflage d'air en lui donnant une forme correspondant à la forme du cadre. De plus, on évite quasiment tout contact de la face arrière de la bande d'affiches avec le dispositif de support, du fait da la création d'une lame d'air entre le cadre et la bande d'affiches. On évite ainsi les inconvénients susmentionnés de la technique antérieure.Thanks to these provisions, it inflates the poster band under the effect of air blowing giving it a shape corresponding to the shape of the frame. In addition, virtually any contact of the back side of the poster band with the support device is avoided due to the creation of an air gap between the frame and the poster band. This avoids the aforementioned disadvantages of the prior art.

Dans des modes de réalisation préférés de l'invention, on peut éventuellement avoir recours en outre à l'une et/ou à l'autre des dispositions suivantes :

  • la bande d'affiches est sensiblement imperméable à l'air ;
  • la bande d'affiches est maintenue en tension ;
  • la bande d'affiches est maintenue en tension par les rouleaux ;
  • les rouleaux sont sensiblement verticaux ;
  • le cadre comporte deux premiers côtés opposés sensiblement perpendiculaires aux rouleaux, qui présentent une forme générale convexe de convexité tournée vers l'avant, de sorte que la bande d'affiche présente elle-même une forme convexe de convexité tournée vers l'avant entre les rouleaux ;
  • les deux premiers côtés du cadre présentent des formes identiques ;
  • les deux premier côtés du cadre présentent
In preferred embodiments of the invention, one or more of the following may also be used:

  • the poster band is kept in tension;
  • the poster band is held in tension by the rollers;
  • the rollers are substantially vertical;
  • the frame has two first opposed sides substantially perpendicular to the rollers, which have a generally convex convexity shape facing forward, so that the poster band itself has a convex convexity shape facing forward between the rolls;
  • the first two sides of the frame have identical shapes;
  • the first two sides of the frame

chacun une face avant adjacente à la face arrière de la bande d'affiches, de largeur comprise entre 5 et 12 cm ;

  • le cadre comporte en outre deux seconds côtés sensiblement parallèles aux rouleaux, lesdits seconds côtés présentant chacun un bord avant arrondi ;
  • le panneau d'affichage comporte un dispositif électronique de commande qui commande les rouleaux et qui est adapté pour relâcher partiellement la tension de la bande d'affiche lorsque ladite bande d'affiche est mise en mouvement par les rouleaux.

  • and the figure 5 is a block diagram of the display device of the figure 1 .

Sur les différentes figures, les mêmes références désignent des éléments identiques ou similaires.In the different figures, the same references designate identical or similar elements.

La figure 1 représente un dispositif d'affichage 1, consistant par exemple en une colonne de forme générale cylindrique qui comporte un bâti 2, fixé au sol et des fenêtres 3 optiquement transparentes, présentant par exemple des formes de portion de cylindre.The figure 1 represents a display device 1, consisting for example of a column of generally cylindrical shape which comprises a frame 2, fixed to the ground and optically transparent windows 3, having for example cylinder portion shapes.

Dans chaque fenêtre 3 sont présentées des affiches appartenant à une bande d'affiches 4 défilante.In each window 3 are presented posters belonging to a strip of posters 4 scrolling.

La bande d'affiches 4 est enroulée sur deux rouleaux parallèles 5, par exemple des rouleaux verticaux, dont un seul est visible sur la figure 1.The poster strip 4 is wound on two parallel rollers 5, for example vertical rollers, only one of which is visible on the figure 1 .

Ces rouleaux sont motorisés et commandés par un dispositif de commande électronique, comme décrit plus en détail ci-après, de façon à pouvoir faire défiler séquentiellement les affiches formant la bande d'affiches 4, pour présenter successivement chacune de ces affiches derrière la fenêtre 3.These rollers are motorized and controlled by an electronic control device, as described in more detail below, so as to be able to scroll sequentially the posters forming the poster band 4, to successively present each of these posters behind the window 3 .

Entre les rouleaux 5 est disposé un dispositif de support d'affiche 6, fixé au bâti 2, qui est adapté pour soutenir la face arrière de la bande d'affiches 4, c'est-à-dire la face de cette bande d'affiches qui n'est pas visible du public.Between the rollers 5 is arranged a poster support device 6, fixed to the frame 2, which is adapted to support the rear face of the poster strip 4, that is to say the face of this strip of posters that is not visible to the public.

Comme on peut le voir sur les figures 1 à 3, ce dispositif de support 6 présente une forme générale de portion de cylindre d'axe vertical et de convexité tournée vers l'extérieur du dispositif d'affichage, c'est-à-dire vers l'avant.As can be seen on the Figures 1 to 3 , this support device 6 has a general shape of cylinder portion of vertical axis and convexity facing the outside of the display device, that is to say towards the front.

Plus précisément, ce dispositif de support 6 comporte un cadre 7 qui comprend :

  • deux premiers côtés horizontaux 8, respectivement inférieur et supérieur, en forme générale d'arc de cercle,
  • et deux deuxièmes côtés 9 rectilignes et verticaux.
More specifically, this support device 6 comprises a frame 7 which comprises:
  • first two horizontal sides 8, respectively lower and upper, in the general shape of a circular arc,
  • and two second rectilinear and vertical sides 9.

Chacun des premiers côtés 8 comporte une face avant 8a en forme de portion de cylindre, qui est adjacente à face arrière de la bande d'affiche 4 et qui présente une largeur h dans le sens vertical. Cette largeur h est comprise par exemple entre 5 et 12 cm et peut être notamment de l'ordre de 10 cm.Each of the first sides 8 has a front face 8a in the form of a cylinder portion, which is adjacent to the rear face of the poster band 4 and has a width h in the vertical direction. This width h is for example between 5 and 12 cm and can be in particular of the order of 10 cm.

Par ailleurs, chacun des deuxièmes côtés 9 comporte un bord avant 9a (voir figure 3) qui est adjacent à la face arrière de la bande d'affiches 4 et qui peut être relativement mince, par exemple d'une largeur comprise entre 5 et 10 mm. Ce bord avant 9a est de préférence à section arrondie, comme on peut le voir sur la figure 3.Moreover, each of the second sides 9 has a front edge 9a (see figure 3 ) which is adjacent to the rear face of the poster band 4 and which may be relatively thin, for example of a width of between 5 and 10 mm. This front edge 9a is preferably rounded section, as can be seen on the figure 3 .

Le dispositif de support 6 comporte en outre un fond 10 qui peut être avantageusement réalisé d'une seule pièce avec le cadre 7, par exemple en Plexiglas® translucide, ou autre. Le fond 10 présente une forme générale de tronçon de cylindre et peut lui-même présenter une épaisseur comprise par exemple entre 5 et 10 mm. Le fond 10 est disposé en retrait vers l'arrière par rapport aux faces avant 8a et aux bords avant 9a du cadre, de façon à délimiter avec le cadre 7 une chambre à air 11 de profondeur P comprise par exemple entre 2 et 4 cm, par exemple de l'ordre de 3 cm.The support device 6 further comprises a bottom 10 which can be advantageously made in one piece with the frame 7, for example translucent Plexiglas®, or other. The bottom 10 has a general shape of a cylinder section and may itself have a thickness of, for example, between 5 and 10 mm. The bottom 10 is recessed rearwardly relative to the front faces 8a and the front edges 9a of the frame, so as to define with the frame 7 an air chamber 11 of depth P of for example between 2 and 4 cm, for example of the order of 3 cm.

Dans le fond 10 du support d'affiche 6 sont ménagées une ou plusieurs ouvertures 12 qui communiquent chacune avec une soufflante 13 située à l'arrière du fond 10, comme représenté sur la figure 4. Chacune des soufflantes 13 souffle de l'air en permanence dans la chambre à air 11 de façon à y créer une légère surpression, par exemple de l'ordre de 20 à 30 Pa. Cette surpression fait "gonfler" la bande d'affiche en regard de la chambre à air 11 et lui confère une forme cylindrique correspondant à la forme générale du dispositif de support 6.In the bottom 10 of the poster support 6 are provided one or more openings 12 which each communicate with a fan 13 located at the rear of the bottom 10, as shown in FIG. figure 4 . Each of the blowers 13 blows air permanently into the air chamber 11 so as to create a slight overpressure, for example of the order of 20 to 30 Pa. This overpressure "inflates" the poster band in view of the air chamber 11 and gives it a cylindrical shape corresponding to the general shape of the support device 6.

De plus, cette surpression crée une légère fuite d'air sur tout le pourtour du dispositif de support 10, entre le cadre 7 et la face arrière de la bande d'affiche 4, d'autant que la bande d'affiches est généralement en matériau sensiblement imperméable à l'air. Cette fuite crée une lame d'air permanente séparant la face arrière de la bande d'affiche 4 et le dispositif de support 6, en évitant ou tout au moins en limitant les frottements entre ladite face arrière de la bande d'affiche et le dispositif de support 6.In addition, this overpressure creates a slight air leakage around the entire periphery of the support device 10, between the frame 7 and the rear face of the poster band 4, especially since the poster band is generally made of material substantially impervious to air. This leak creates a permanent air gap separating the rear face of the poster band 4 and the support device 6, avoiding or at least limiting the friction between said rear face of the poster band and the device. of support 6.

Comme on peut le voir sur la figure 4, sur la face arrière du fond 10 peuvent également être fixés des dispositifs d'éclairage 14, par exemple des tubes fluorescents, permettant de réaliser un rétro éclairage de l'affiche en cours de présentation au travers dudit fond 10, lequel est de préférence translucide.As can be seen on the figure 4 , on the rear face of the base 10 can also be fixed lighting devices 14, for example tubes fluorescents, making it possible to carry out a backlighting of the poster being presented through said bottom 10, which is preferably translucent.

Par ailleurs, à l'arrière du fond 10 peuvent également être logés des moteurs électriques 15, par exemple des moteurs asynchrones, qui entraînent chacun l'un des rouleaux 5 par l'intermédiaire d'un dispositif de transmission, par exemple une courroie 16.Furthermore, behind the bottom 10 can also be housed electric motors 15, for example asynchronous motors, which each drive one of the rollers 5 by means of a transmission device, for example a belt 16 .

Ces moteurs peuvent être commandés par exemple comme expliqué dans le document FR-A-2 812 750 , au moyen de deux variateurs 17 (VAR 1,VAR 2) visibles sur la figure 5, commandés par un dispositif électronique de commande 18 (AUT) tel qu'un automate industriel ou autre. Lorsqu'on fait défiler la bande d'affiche 4 horizontalement pour changer l'affiche en cours de présentation, on effectue une légère mise en tension de la bande d'affiche en alimentant le moteur du rouleau entraînant roulé la bande d'affiche avec une fréquence légèrement supérieure à l'autre rouleau. Avantageusement, l'automate 18 peut être adapté :

  • pour que cette tension soit relativement faible au cours du mouvement de défilement (correspondant par exemple à une différence de fréquence d'1 à 2 Hz sur les variateurs 17),
  • et pour augmenter cette tension lors de l'arrêt de la bande d'affiche.
These motors can be controlled for example as explained in the document FR-A-2,812,750 , by means of two variators 17 (VAR 1, VAR 2) visible on the figure 5 , controlled by an electronic control device 18 (AUT) such as an industrial controller or other. When the poster strip 4 is scrolled horizontally to change the poster during the presentation, the display strip is lightly tensioned by feeding the motor of the driving roller which rolls the poster strip with a slightly higher frequency than the other roll. Advantageously, the automaton 18 can be adapted:
  • so that this voltage is relatively low during the scrolling movement (corresponding for example to a frequency difference of 1 to 2 Hz on the drives 17),
  • and to increase this tension when stopping the poster band.

Comme on peut le voir sur la figure 5, l'automate 18 peut également commander les soufflantes 13 (V1, V2) et peut aussi être relié à un capteur 19 (C), connu en soi, adapté pour détecter des repères sur la bande d'affiche de façon que le défilement de cette bande soit arrêté en correspondance avec les affiches qu'elle porte.As can be seen on the figure 5 , the automaton 18 can also control the blowers 13 (V1, V2) and can also be connected to a sensor 19 (C), known per se, adapted to detect marks on the poster band so that the scroll of this tape is stopped in correspondence with the posters it carries.
