Definitions

• the present invention relates to a device for selective display of information for advertising purposes.
• the invention applies more particularly to display devices of the type of that comprising:
• 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.
• an elastic return means such as a spring
• French Patent No. 2,647,246 provides a solution for making such a display device. To this end, this device comprises:
• each of these supports being intended to receive a cartridge (roller) oriented perpendicular to the axis of travel of the conveyor,
• 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.
• the technical problem to be solved by the object of the present invention is therefore to propose a display device that is simple to implement, inexpensive, allowing the order and duration of presentation of each poster to be easily defined and modified. and to minimize the idle time between display and display operations.
• the basic 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.
• a display device offers many advantages because it allows minimize downtime between display and display operations, since:
• the above 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.
• the process is dynamic since it is he who comes next to the means of extracting a selected poster from one or the other of the stores and which ensures the course and presentation of a poster behind the window.
• 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.
• 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.
• Figure 1 is a partially exploded view of such a device.
• Figure 2 is a vertical sectional view of the same device.
• Figure 3 is a detail view of an element of this device.
• Figure 4 is an enlarged view of a detail of embodiment of this device.
• Figures 5a, 5b, 5c, 5d are schematic views of this device, illustrating a display cycle.
• the display device of the invention consists of a self-supporting frame 100 on which are arranged:
• the self-supporting frame 100 which will be described a little more in detail at the end of the description consists in particular of a rigid framework which aims to serve as a logical structure for the various dynamic organs of the device (which will be detailed below) in their realization) adapted to be interchangeable and respect the modular architecture.
• the stores 200a and 200b located in the context of the invention at the top and bottom of the frame 100 are intended to ensure the dynamic storage of rollers 210a, 210b containing posters wound on themselves 211a, 211b information carrier for advertising purposes.
• the poster 211a illustrated by way of example in the drawing of FIG. 3 is provided at one of its ends with an elastic return means not illustrated, making it possible in particular to ensure automatic winding of displays it inside its roller 210a in the absence of any external action.
• 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.
• 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 acting as an extraction means allowing, using a suitable attachment means, to annihilate the opposite force of the spring return means and to unwind the poster 211a out of its roll 210a.
• a rod 212a is threaded acting as an extraction means allowing, using a suitable attachment means, to annihilate the opposite force of the spring return means and to unwind the poster 211a out of its roll 210a.
• the poster 211a takes place outside of the roller 210a while remaining taut by the opposite tension exerted by the return force E of the spring.
• the spring return force ensures the winding of the poster 211a inside the roller 210a as shown by the arrow E.
• the stores 200 a and 200 b each consist of an endless chain 220 a, 220 b, 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.
• the embodiment of the stores 200a and 200b is given by way of 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.
• 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.
• the magazines 200a and 200b thus defining independent modular assemblies, can also be quickly interchanged in the display device of the invention.
• the braced flanges 110 and 120 constituting the self-supporting frame 100 of the device are provided with notches 111 and 121 opening out towards the rear of the frame and allowing the rapid installation or removal of a magazine 200a or 200b.
• 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 specific application conditions, in particular to avoid problems of reflection of incident light, the display window 300 may be devoid of any protective glazing.
• 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.
• 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.
• the endless belt 410 is fitted with two hooks 411a, 411b arranged opposite and acting as attachment means for extracting the posters 211a or 211b.
• hooks 411a, 411b are, on the one hand, sufficiently spaced from one another, and, on the other hand, sufficiently open to allow the attachment or unhooking of the rod forming the aforesaid extraction means 212a and 212b posters 211a, 211b.
• 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 211a 212b possibly protruding posters 211a or 211b and / or in eyelets formed along the length of the hem formed at the ends of the posters 211a, 211b to receive said rods.
• 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.
• the guide devices 440a, 440b have the particular advantage of giving an angle of inclination to the hooks 41 a, 41 lb 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, 41 lb outside the path of the rollers 210a, 210b, and avoid any interference with those -this.
• these guide means are also used as end of travel detectors for the running of the endless belt 410.
• the display cycle of the above device is illustrated in the drawings of the figures.
• FIG. 5a illustrates the display device according to which a poster 211a of the storage magazine 200a is presented behind the display window 300 and held in this position by the hook 411b of the unwinder 400 in the low position of the device at the level from store 200b.
• FIG. 5b is intended to illustrate the setting in motion of the magazine 200b so that the roller 210b is positioned in front of the hooking means 41 1a, 41 lb of the unwinder 400.
• the object of FIG. 5c is to illustrate the upward movement of the unwinder 400 which has enabled the hook 41 lb to ensure the attachment of the rod 212b corresponding to the poster 211b wound in the selected roller 210b, so that the poster 211b can take place behind the display window 300 at the same time as the poster 211a of the roller 210a of the magazine 200a is automatically wound in its roller under the effect of its return spring and guided by the movement ascending from unwinder 400.
• FIG. 5d illustrates the poster 21 lb entirely unrolled behind the window 300 and the unhooking of the rod 212a from the hook 41 la, so that the roller 210a is released from the unwinder 400. A new display cycle can then begin for positioning a new poster for store 200a.
• the device according to the present invention has several advantages over existing devices:
• ⁇ stores the posters in a minimum volume 1 and offers a very small total footprint thanks to a front surface almost identical to the useful surface of the display window, as well as a very reduced depth due to the dynamic storage of stores and by their constitution.
• ⁇ is simple to use and maintain, reliable and inexpensive, thanks in particular to a very limited number of components, each of them performing a function whose implementation will be controlled by tradesman.
