Definitions

• the present invention relates to a device for individually displaying, in a selective manner, the different posters of a set of posters each carrying a message, advertising or other, by positioning them successively behind a display window.
• This device finds application in particular in the field of advertising or traffic information.
• the invention can be provided at a fixed post, on display panels with changing messages, or on an advertising vehicle in circulation, in particular within an urban traffic flow.
• the invention more specifically relates to a display device by which there is total freedom for the exposure of the selected poster, both in terms of its frequency and its duration, as well as for the 'order of their scrolling.
• the advertising contract binding the display to its customers may provide that the exposure cycles of the different posters are not the same for all posters.
• each poster has a well-defined frequency and exposure time, which can however be modified over time.
• the subject of the invention is a display device making it possible to selectively display individually, the various posters of a set by positioning them successively behind a display window, in which each of the posters is fixed by its upper edge, detachably, to a flexible leader strip capable of being wound, at least partially, on a rotary receiving drum, this device comprising a series of electric reduction gears controlled by a programmable central unit, and each adapted to drive selectively, in one direction or another, one of said drums so as to be able to bring said poster either into a high retracted position, in which it does not appear behind the window of display, either in a low deployed position, in which it is located opposite said window, the deployed positions of the various posters being inscribed in separate parallel vertical planes, slightly spaced from one another.
• the main objectives of the invention are, thanks to the implementation of simple, inexpensive, easy to use and maintain means, to be able to:
• each of the posters consists of a hem acting as a sheath, into which is inserted a horizontal ballast bar ensuring the tensioning of the poster, the two ends of this bar projecting outside the sheath, on each side of the poster and being each provided with a removable annular or semi-annular slide which surrounds with a certain play a vertical guide rod.
• the arrangement of the device and the dimensions of its various components are such that when a poster is in the retracted position, neither the constituent elements of its support, nor the poster itself, interfere with the viewing of others. posters, when these are deployed.
• Each of said sliders consists of a stirrup which, seen from above, has the general shape of a "U” whose bottom surrounds the guide rod while its branches embrace the end of the bar and are fixed to it by removable connecting members, such as screws.
• the guide rods are alternately offset laterally one with respect to the other by a given distance, which gives them, seen from above, a staggered arrangement.
• control means comprise at least one optoelectronic device, the detection line of which extends horizontally, on one of the sides of the set of posters, perpendicular to their deployment plane, in a position such that this line is cut by one of the ends of each ballast bar, during the upward or downward movement of this bar.
• the detection line extends at the base and / or in the upper part of the device, and is adapted to control the arrival, in the low position, ie at the end of its deployment stroke, and / or in high position, that is to say at the end of the retraction stroke, of at least one poster.
• the invention also relates to an advertising vehicle equipped with at least one device such as that which has just been described.
• this vehicle comprises several devices and, correspondingly, several viewing windows, these different devices being controlled from a common programmable central unit.
• the advertising vehicle may in particular consist of a van, the body of which has the general shape of a rectangular parallelepiped, the latter comprising three viewing windows, two of which are located on its lateral faces, and the other on its rear face, said central unit. common being likely to be programmed in such a way that the same advertising message is displayed simultaneously in at least two of these windows.
• An additional display window (fourth window) can also be advantageously provided above the cabin, in front of the upper front part of the body, at the air deflector (nasturtium).
• the invention also relates to a vehicle for transporting passengers, such as a bus, equipped with at least one display device of this type, and the viewing window of which is arranged in the rear face of the vehicle.
• the invention also relates to a fixed advertising panel equipped with at least one device such as that which has just been described.

• the device comprises a set of five posters which can be positioned in turn, selectively, behind this window.
• Figure 1 shows the flexible support receiving one of the posters.
• This support is formed of a flexible leader strip 1, such as a thin oilcloth, which is wound on a rotary cylindrical drum 5, with a horizontal axis 50. The latter is parallel to the general vertical plane, containing the viewing window, not shown.
• Driving means which will be described later, make it possible to rotate the drum 5 in one direction or the other, as is symbolized by the double arrow F in FIG. 1.

• the deflection takes place at approximately right angles, the part of the strip connecting the roller 6 to the drum 5 therefore being approximately horizontal
• flanges 60 are provided forming stops for the lateral edges of the strip. These flanges 60 have a conical wall, which converges inwards, so as to promote the correct centering of the strip, both when it is unwound and when it is wound.
• the free end of the strip 1 has an edge zone 10 intended to receive and retain the upper edge 40 of a poster 4, this in an easily removable manner.
• the poster is made of a usual material, thin and flexible, but mechanically resistant and not crumplable, such as strong paper, a plastic film or fabric for example. It carries a message M, for example printed, so centered and dimensioned that it is intended to be fully visible through the viewing window (not shown in Figure 1), whose dimensions are slightly smaller than those of l poster.
• the attachment is by a gripping system with hook-and-loop fabrics, loops and hooks, of the type widely distributed under the trade name "NELC O" (registered trademark).
• the transverse end edge 10 of the leader strip 1 carries, on its face opposite to that facing the viewing window, one of the two elements of the gripping fabric 10A, for example the hooks.
• each poster 4 is lined, in its upper border area 40, with the other element of the gripping fabric 40A - in this case the loops -.
• fixing the top of the poster against the leader strip is very easy, by simple pressure, the upper front edge of the poster adhering against the back of the edge 10.
• the pressure generated between these two elements during winding promotes their mutual connection.
• the lower edge 41 of the poster consists of a hem, or sheath, produced by folding, then gluing or sewing, of its lower end portion. It opens out on each side of the poster, and forms an opening of sufficient section to allow a ballast bar 2 forming a counterweight therein. It is for example a metal bar of rectangular or square section; its length is slightly larger than the width of the poster, so that its end portions 20, 20 ′ project on each side of the sheath
• the weight of bar 2 must be sufficient to correctly tension the poster, in a vertical direction, while it is attached to the leader strip; if necessary, additional weights of tabular shape can be fitted onto the bar, in particular at its ends.
• the bar must not be excessively heavy so as not to counteract too much the action of the motor during winding, that is to say when the poster is raised; otherwise, excessively powerful motors should be used.
• the drum 5 If the drum 5 is rotated in the opposite direction, the strip 1 is wound almost completely on the drum, while the bar 2 comes to occupy a high position, above the level of the viewing window.
• the poster is therefore in a retracted position, folded over the deflection roller 6.
• FIG. 3 shows how a set of five poster supports such as the one just described are installed in the device.

• Each poster is guided in translation and correctly maintained in its vertical plane of movement by guide members which will now be described.
• These members include a pair of slides 7, 7 'carried by the ends 20, respectively 20', of the ballast bar 2. Said slides are movable in translation along vertical rods 3, respectively 3 ', arranged laterally, at the outside the frame of the viewing window.
• the slide 7 is a “U” shaped stirrup (for example a flat iron folded into a U), the semi-cylindrical bottom of which surrounds the rod 3.
• the latter is for example metallic, too. It has a circular section of diameter slightly less than the width of the “U” -shaped stirrup 7, so as to provide good guidance, without friction, of the latter.
• the part 7 is fixed to the bar portion 20 in an easily removable manner.
• the spacing of the two cheeks 72 constituting the branches of the "U" corresponds to the thickness of the bar 2.
• the portion 20 is crossed by a pair of transverse bores 21.
• the cheeks 72 are pierced with openings 70 intended to come into correspondence with the latter when the stirrup 7 comes to cap the end of the bar.
• the openings 70 are tapped holes, allowing fixing by means of screws 710.
• each rod is substantially centered inside the part 71, 71 'of the stirrup which it passes through.
• the rods 3, 3 ' are fixed by their upper and lower ends to the boxes 82, respectively 81, in them by suitable means, not shown.
• the ballast bar always remains perfectly horizontal.
• the rod being trapped inside the caliper, the risk of inadvertent escape of the caliper is zero, even if the device is exposed to sudden movements, as can happen when it equips a vehicle. .
• the poster to be replaced is deployed (bar 2 in the lower position).
• the stirrups 7, 7 ′ are removed, which makes it possible to remove the ballast bar 2 from the hem 41.
• the upper zone 40 is detached from the attachment edge 10 of the leader strip.
• the installation of the new poster is done by the reverse operations: fixing of the upper border against the bank 10; fitting of the bar 2 in the hem 41; fixing the stirrups 7, 7 '(previously placed around the rods 3, 3') at the ends of the bar 2.
• the rods 3, 3 ′ are advantageously staggered on each side of the device, as seen in FIG. 4.
• Each rod is offset transversely by a certain distance "m” from the neighboring rod (s). This prevents the stirrups 7 or 7 'of two neighboring bars from being too close to each other.
• FIG. 6 represents an optoelectronic detection system, for example with photoelectric cells, mounted at the base of the device, on one of its sides. It comprises a transmitter 200 and a receivers 201 of known types, the radiation line of which, referenced 2000, extends horizontally, transversely to the plane of the posters. It is located opposite one of the end portions 20 of the set of ballast bars 2.
• the detection system When a poster reaches the end of the deployment stroke (low position), the line 2000 is thus cut, activating the detection system which sends a signal corresponding to this information to the central control unit.
• This system makes it possible to detect anomalies, in particular in the event of a poster jamming against an obstacle, a breakdown or an unexpected jamming of a drum.
• the central unit can then carry out an ad hoc command, for example triggering an alarm or lighting an indicator.
• a similar detection system is advantageously provided in the upper part of the device, or in an intermediate zone, halfway up.

• the central unit controls the motors via a relay card, or interface, 1000.
• Certain posters may of course be displayed longer and / or more frequently than others, depending on the program.
• substitution of one poster for another can be done in an extremely short time, since the retraction of the previous poster and the deployment of the new poster can be done simultaneously, in masked time.
• the 4A presents a window 400 which lets see the poster 4B located behind it. It is a simple opening crossing the poster, or a transparent area. Thus, depending on the degree of movement of the strip IB which carries the poster 4B placed behind the poster 4A, these are different zones of this poster which will be visible at through said window 400. Consequently, if one affixes on the posterior poster of the drawings, messages or other different inscriptions, able to come selectively opposite window 400, one can modify in an evolutionary way the scene displayed, visible on previous poster. In the example of Figures 8 and 9, the window is a "bubble" representative of the reflection of an advertising figure.
