Oscillating supports can be tilted between rolling and unrolling positions using jacks (9, 10).

Description

The invention relates to an oscillating dynamic display device intended to the sequential presentation of advertising or other posters, on the way public or private locations outside.

Such devices are widely used today and occur most time in the form of rectangular frames, large enough to be seen from a distance, in which are placed several posters that can be presented successively according to a sequence given at the sight of observations by an electromechanical system. Posters can be lit or not.

The sequential display systems for posters in the panel are come in different forms.

For example, posters can be cut into strips, strips of the same poster being fixed on the faces of prisms whose axes longitudinal are parallel, these prisms can rotate around their axes. The prisms are arranged side by side in the frame in the direction vertical or horizontal and are rotated step by step so that align the faces carrying the bands simultaneously in the plane of the frame of the same poster and together form a surface showing the full picture under the panel for a time predetermined.

The disadvantage of this system is that it only allows sequential display of three posters, since only triangular prisms can rotate while simultaneously presenting a face in alignment with that of a neighboring prism while forming a continuous surface.

According to another system, the posters can be placed end to end and the assembly thus obtained is mounted at its ends on two rollers, driven by an electric motor, arranged on two opposite sides of the frame. The poster train wound on one of the end rollers is unrolls from it to wrap on the opposite roll while not advancing not to present the full poster on the surface of the frame for a predetermined time.

The disadvantage of this system is that the posters located in end of sequence are displayed only once during a sequence and at a significant time interval while all the others posters are presented in the frame twice; a first time during unrolling in one direction and a second time during unrolling in the other direction. In addition, the display frequency of each poster is not not regular, except for the posters located in the middle of the strip.

A solution according to European patent 0 740 824 consists in having the rolls of posters on supports distributed on an endless strip moving step by step. An unwinder with coaches circulates between two idler rollers, located at two opposite ends of a frame display panel and allows to hang a means of extraction of the poster to unroll it while the poster previously unrolled during the opposite movement of the tape is wound again under the effect of means reminders. Thanks to such a system, it is possible to obtain a sequential display regular of several posters. This system allows the display of a large number of posters. But experience shows that advertising by such signs are only effective for posters often presented in the framework, that is to say for a relatively small number. Therefore, the system is far too complex due to the large number of parts in movement and therefore more expensive than necessary.

European patent 0 649 554 describes a similar system in which the poster rollers are arranged on rotating feeders at the ends opposite of the panel. It has the same disadvantages as the previous.

The invention aims to overcome these drawbacks by creating a system display with which posters are presented, as part of the display panel, in a regular sequence as to the order of succession and the time interval between two successive displays of the same poster, while avoiding too great a complexity of the whole and reducing the cost.

This object is achieved according to the invention, for a display device oscillating dynamics intended for the sequential presentation of posters, having a rectangular frame in the interior surface of which posters are placed parallel to two opposite sides of the frame and whose the axes are arranged in turn along at least one of these sides and are rotatably mounted on a mobile support located at each of their ends, the posters being unrolled thanks to a drive device moving between these two sides parallel to them, between a position where the poster is rolled up and a position where the poster is unrolled, the poster wrapped near one side being gripped by its free edge by the device drive and unwound to the opposite side of the frame, the device having means for automatically rewinding the poster when the drive device returns to its first position, characterized in that the mobile supports are oscillating supports that can tilt between at least two tilting positions under the effect of a jack of actuation, in each of which the axis of the roll of a poster is placed in its unwinding and rewinding position of the poster along the respective side of the frame.

According to the invention, the drive device is constituted by a carriage in the form of a beam movable in translation in the frame, in parallel on said sides, between a first position for grasping the free edge of the display where it is adjacent to the opposite parallel side and in which the poster is fully unrolled and presented on the surface of the frame.

According to a characteristic of the invention, the poster is provided with ends of its edge free of coaches allowing to grasp this edge and pull it out to unroll the poster. These coaches can be trained in ends of a profile whose length is roughly equal to that of the edge of the poster and present a hook-shaped section.

According to another characteristic of the invention, the carriage includes coaches on each of its opposite sides to engage in corresponding trainers of the poster in order to pull it out. These coaches may have a hook-shaped section corresponding to that of the poster coaches.

According to a particular characteristic of the invention, the trainers of the carriage have elasticity to bend between a position for hanging the poster coach and an erase position by report to poster coach. They can also be rigid and mounted tilting on the carriage between a hooking position of the coach poster and an erasing position relative to said coach poster, with return means in the hanging position.

The invention will be better understood by means of an embodiment shown in the accompanying drawing, in which:

Figure 1 shows schematically in perspective the display system according to the invention in which a pair of poster rollers is positioned on each of two opposite edges of the frame;

Figure 2 shows schematically in perspective the means of driving posters;

Figure 3 schematically shows the loading operations of posters and display.

In FIG. 1, the device according to the exemplary embodiment has a first oscillating support 1 mounted on a vertical side of the frame 7, at its part lower, so as to tilt around an axis C1 and carrying two bearings (not shown) intended to support the ends of two axes of poster rollers 3 and 4. An identical oscillating support is arranged symmetrically on the opposite side of the frame to support the other end of the axis of the rollers. Poster rollers 3 and 4 are arranged horizontally between the corresponding opposite supports.

A second oscillating support 2 identical to the previous one is mounted on the same side of the frame at its top so as to tilt around a C2 axis and carries poster rolls 5 and 6. This support is more movable along this side of the frame. An identical oscillating support is also symmetrically arranged on the opposite parallel side of the frame to support the other end of the axis of the rollers.

Each poster roll has a tubular hub to which is attached one end of the poster wound on the hub. The tubular hub is subjected to the action of a recall system which tends to make it rotate in the direction of the poster winding. Each poster is bound on its edge free to a profile provided at its ends with coaches 11 with cross section hook shape that allows you to grab and unroll it by pulling on the coaches.

A carriage 8, in the form of a beam, is mounted, movable vertically, by its ends on the two opposite sides of the frame 7 carrying the supports oscillating and can move parallel to the horizontal edges of the panel 7. The carriage has at each end of its lower edges and upper, coaches 12 and 13, respectively, of the same type as those mounted on posters and mounted to hang the coaches 11 correspondents of a poster when the hooks are opened face, when moving in one direction, and to move away from it elastically being repelled by them, when moving in the opposite direction, when they present with opposite openings.

The oscillating supports 1 and 2 can be tilted by jacks 9, 10, respectively, in two positions in each of which one of the two poster rollers supported by the respective oscillating support is presented towards the front of frame 7 so that the trainers of the poster are on the path of the corresponding coaches of the carriage 8. They can also take a neutral intermediate position in which the carriage passes in front of the rollers without the coaches entering contact with each other.

à partir de la position I (figure 3), les supports oscillants supérieurs 2, en position intermédiaire neutre, sont tout d'abord abaissés (II) au niveau des supports oscillants inférieurs 1 pour être mis à portée de l'opérateur et les deux rouleaux d'affiche 5 et 6 sont mis en place sur les paliers correspondants des supports 2 et maintenus par tout moyen connu (III). Les supports supérieurs 2 sont alors remontés (IV) jusqu'à leur position de fonctionnement (V). Les rouleaux d'affiche 3 et 4 sont mis en place de la même manière que les rouleaux 5 et 6.

The system works as follows:

from position I (FIG. 3), the upper oscillating supports 2, in the neutral intermediate position, are first lowered (II) at the level of the lower oscillating supports 1 so as to be placed within the reach of the operator and both poster rollers 5 and 6 are placed on the corresponding bearings of the supports 2 and maintained by any known means (III). The upper supports 2 are then raised (IV) to their operating position (V). The poster rollers 3 and 4 are set up in the same way as the rollers 5 and 6.

The oscillating supports 2 then tilt in one of the positions in which the coaches 11 of the poster 6 appear on the path of coaches 13 of the carriage 8 (VI).

The carriage 8 then begins its movement from its high position stopped at the top of panel 7 (VII). Passing by coaches 11 of the poster of the roller 6, the upper coaches 13 engage in the coaches 11 and pull the poster 6 down by unrolling it against the reminder system. When the carriage 8 comes to a stop in the low position (VIII), the poster for roll 6 is fully unrolled and presented on the surface of the panel delimited by the frame 7. The coaches 12 disappear and the oscillating support 1 then switches to the position in which the two coaches 11 of poster 3 appear on the path of the two coaches 12 of carriage 8.

Once the display time has elapsed, the carriage 8 performs the movement reverse and go up (IX). Passing by coaches 11 of the poster of the roller 3, its coaches 12 engage on these and draw the poster 3 which unrolls upwards until the carriage has reached its position high. At the same time, the poster for roll 6 is rolled up again thanks to the reminder system.

In this position, the upper coaches 13 of the carriage 8 are released from the coaches 11 of the poster of the roller 6 which is again the wound state. The jack 9 is then actuated and rotates the supports oscillating 2 around their axis C2 to bring the poster roll 5 into the position previously occupied by the poster roller 6 (X).

After expiration of the predetermined exposure time of the sequence display, the carriage 8 starts in the opposite direction. Coaches 13 of carriage engage in the coaches 11 of the roller 5 and the carriage descends (XI) to its lowest point by unrolling the poster for scroll 5 while the poster for roll 3 is rolled up again.

Once the low point reached by the carriage 8 (XII), the lower coaches 12 thereof are disengaged from the coaches 11 of the poster for the roller 3. The cylinder 9 then swings the support 1 so as to bring the roller poster 4 in the position previously occupied by the poster roller 3. Going up (XIII), the carriage 8 unrolls the poster for the roller 4 and the poster for roll 5 is rewound.

When the carriage 8 has reached its high point, the jack 10 then tilts the support 2 in the other direction and return the poster roll 6 to the position it occupied at the start of the display sequence. The presentation cycle of the four posters is then repeated until a change of the four poster rolls be done.

In order to prevent the stop of the coaches 12 and 13 on the coaches 11 of the posters when the carriage reaches the end of its travel, coaches 12 and 13 can be mounted flexibly so as to move apart when passing on a trainer 11 of a poster of one of the rollers. They can also be tiltable on the carriage 8 with a return spring for return to the hooking position of the coaches 11.

The display sequence is controlled by a computer program, an electronic card, a programmable controller or the like, with configurable scrolling and exposure times.

The movement of the carriage is electrically controlled, for example with two motors, and reversed for example by end switches race. The raising and lowering of the supports 2 are controlled by a operator operated switch during loading and unloading of rollers.

The cylinders 9 and 10 can be electric, mechanical or hydraulic.

The panel may have lighting behind the poster. He can be placed outside or in an indoor public place.
