Description

Device for displaying poster sets individually and selectively

In this type of system, the posters are usually placed end to end on an elastic support to form a single long strip.

This may be such an endless strip as provided, for example, in FR-A-2 579 810 and US-A-1 530 888.

According to such other possible embodiments as described in FR-A-2 692 395, FR-A-2 152 012 and WO / 9203813, a relatively short strip is provided and wound on the drum at each end.

The long strip rolls down like a roll in front of the display window. The strip position is controlled and driven to bring the selected poster directly behind the display window, thereby making it visible to the observer, ie the public, in the case of an advertisement.

In the first four documents described above, the display system is installed on the advertising vehicle.

Continuous control of the display is coordinated by a programmable controller or computer. Such suitable controls, such as photoelectric detector cells and / or mechanical detectors connected to the system, ensure their correct operation.

In current devices, posters are in a single file in a predetermined order, which means that they are displayed in this order through the display window.

This causes a problem when the display order does not correspond to the order.

Therefore, if two non-neighboring posters are to be displayed continuously, one or several of them must be rolled up as a blank view behind the display window. This causes unsatisfactory viewing when the posters are on the move. Moreover, the blank display takes part of the total viewing time.

In this regard, it should be noted that the advertising contract between the advertising contractor and the customer may specify various display cycles for the different posters. Thus, each poster can be assigned a display time and number of times that can change over time.

The order in which the given posters can pass may be determined when the ideas of two or more posters follow, especially as in the case of a "advancing" advertising campaign.

These continuous display requirements are difficult to achieve in a poster set with end to end as in the state of the art.

An object of the present invention is to solve this problem by proposing a display device of the above-described type, wherein the display of the selected poster can be freely selected in terms of the number and duration, as well as the order in which it is displayed.

The specification of the invention FR-A-388 854, a luminous advertising device, is a display comprising a set of screens (bearing advertisements) hung in vertical and parallel planes that can be displayed continuously in the same space. Corresponds to the device. The poster is hidden by winding onto a roller located in the upper part of the device. The set of rollers is driven for the entire set in a predetermined order by a single drive shaft via a motion transfer mechanism that ensures that one screen is wound while the next screen begins to descend.

Thus, in the current device, several advertisements are shown in a predetermined order without being changed.

An object of the present invention is to solve this difficulty by proposing a display device of the type described above, and the display of the selected poster can be freely selected not only by the number and duration but also by the order in which it is displayed.

The device covered in the present invention provides for the selective display of a set of posts individually by continuously positioning several posters in front of the display window.

As with the apparatus described in the specification of FR-A-388 854, each poster is secured to an elastic support member that can be at least partially wound on a rotary receiver drum, and the control assembly can be viewed through the display window. Provided for selectively positioning the poster in its hidden position and in an operating position aligned with the window, the various posters are placed in parallel planes slightly spaced apart.

The above object is achieved according to the invention by the fact that the receiver drum is driven by an electric gearmotor, a programmable controller or a microprocessor that drives these motor sets to selectively display the poster.

Of course, the device is designed such that when the poster is in the hidden position, neither the members forming the support nor the poster itself interfere with the display of another poster in operation.

Moreover, according to a number of additional, beneficial and non-limiting features of the invention;

The resilient support comprises a resilient strip which is extended at the height of the display window by a pair of lateral strips and wound around the receiver drum;

The two straps are connected by a crossbar used to secure the poster;

The poster is attached to this crossbar in a removable state and attached to the transverse edge of the elastic strip;

The device comprises means for tensioning the resilient strip;

The bar is attached to a pair of stretcher cables wound on a return pulley;

At the outlet of the receiver drum, an elastic strip passes over the countershaft roller;

This countershaft roller is tapered at both ends, with its diameter slightly larger in the middle, so that the strip is well-centered;

The display window is vertical, while the horizontal axes of the drum and countershaft rollers are set parallel to the main plane of the window and located in a box on top of the window; In this case the feedback pulley preferably has a horizontal axis and is located in the box at the bottom of the window.

The invention also covers an advertising vehicle with at least one such device as described above.

Other features and advantages of the present invention will become apparent from the accompanying drawings and the following description which show preferred embodiments.

The present invention is directed to a system for selectively and individually displaying posters from a set of posters by continuously placing a set of posters behind a display window.

In particular, the applications of this system include advertising, or road marking and information. This can be used in stationary installations to change message (or other landscape) billboards.

It can also be used in a vehicle, in which case display windows for advertising the messages are provided on the side and rear of the van type vehicle.

In the embodiment described later, as shown in the figure, the display window has a vertical layout and the device comprises a set of five posters that can be selectively positioned in turn behind this window.

Obviously, the choice of five posters is only taken as an embodiment, and a larger number of posters can be adopted.

1 shows an elastic support for receiving one of the posts. This support consists of such an elastic strap 1, a pair of side straps 2 and a pair of side cables 3, such as a thin oil cloth.

The strip 1 forming the top of the support is wound around a rotating cylindrical drum 5 whose axis 50 is horizontal. Axis 50 is parallel to a generally vertical plane, not shown, of the display window.

The driving means shown below can rotate the drum 5 in one direction or the other, as indicated by the double arrow F in FIG.

The strip 1 passes over the countershaft roller 6 and the horizontal axis of the countershaft roller 6 is arranged horizontally on the axis of the drum 5. The reverse movement takes place at about 45 ° and the part of the strip connecting the roller 6 to the drum is arranged approximately horizontal. The roller 6 has a slightly tapered conical shape with the largest diameter in the middle, as shown more precisely in FIG.

At both ends corresponding to the small diameter of the tapered shape, guide plates 60 are provided which act as stoppers for the side edges of the strip. These plates 60 are tapered inwards to prevent the strips from sliding laterally. The slightly tapered shape of the roller 6 allows the strip to be self-aligned so that both the center and the strip 1 can be well centered when the strip 1 is rolled up and released.

The leading end of the strip 1 extends from the side which is not wound around the drum 5 by a lateral strap 2 made of an inelastic fabric. The strap 2 may be attached to the strip 1 by such suitable means as gluing or riveting. The free ends of the strap 2 are connected by cross bars 20.

As shown in Fig. 2, the bar 20 consists of a set of two small thin plates 21, 22 with rounded edges, with two straps 2 inserted between the plates 21, 22. And fixed by rivets 23 passing through the plates 21 and 22 and the strap 2.

The cable 3 is connected to the cross bar 20 and then lowered down to the pulley 7 so that each cable 3 is wound there. These pulleys 7 have two lateral disk guide plates, each forming a groove for the cable (see FIG. 7).

The pulley 7 is a standard return pulley that includes an internal coil spring that tends to rotate constantly in the same direction as the cable is wound into the groove, thus providing a pull on the cable as shown by arrow T in FIG. Add.

This support supports the poster 4 which can be easily removed.

In the embodiment illustrated here, a widely distributed looped and burred "Velcro" fabric fastener is used to secure the poster.

For this purpose, one of the two fabric fastener members, for example a burr fabric, on the lateral edge of the one end of the resilient strip indicated by reference 10 and the side where the cross bar 20 faces the display window. Attached.

The poster 4 is supported on another fabric fastener, for example a looped fabric, at the corresponding position.

Thus, the poster is easily attached to the support by simply pressing the strips together. Once secured, the poster fills the space corresponding to the rectangle formed by the two straps 2, the strip edge 10 and the cross bar 20.

The print 40 on the poster is centered so that it appears appropriately through a display window (not shown in FIG. 1) whose size is slightly smaller than the size of the poster.

By simply comparing Figs. 1 and 3, when the drum 5 rotates in the same direction as the strip is unfolded, the poster is displayed in a vertical plane; It can be seen that the poster is unfolded during deployment as a result of pulling the cable 3 by the return pulley 7.

If the drum 5 is rotated in the opposite direction, the strip 1 will almost completely wind around the drum as the bar 20 moves to its upper position above the height of the display window. The poster is folded back on the countershaft roller 6 in the supported position. In the upper position, the strap 2 is laterally supported by the guide plate 60 of the roller 6.

Figure 5 shows how five poster support sets are installed in such a device as just described above.

In this figure, reference numeral 9 designates a display window comprising a frame 91 and a transparent panel 90, for example a window pane.

The device comprises a chassis 8 which necessarily includes a front panel 82, an upper box 80 and a lower box 81 supporting the display window 9.

The upper box 80 includes an assembled set of drums 5 and guide rollers 6. The lower box 81 includes a set of feedback pulleys 7.

These various members have an operating position in one of the vertical planes a, b, c, d, or e, each of the five resilient supports being parallel to the pane 90. These different planes are separated at regular intervals by small gaps labeled j. Likewise, the plane a of the first poster (closest to the window) is spaced only a short distance k from the pane 90.

The various countershaft rollers 6a, 6b, 6c, 6e and several drums 1a, 1b, 1c, 1d, 1e inside the box 80 occupy as little space as possible, between the poster supports or the posters themselves. It is positioned to avoid any contact.

Similarly, the positions of the various pulleys 7a, 7b, 7c, 7e in the lower box 81 are offset to the minimum to avoid interference with the various cables.

In the embodiment shown here, in particular in Figures 5 and 7, the five pulleys provided on each side of the device are divided into two groups.

The axes of the pulleys 7a, 7b, 7c associated with the first three posters are located in the same horizontal plane but are arranged to be rearward in the transverse direction and in front to secure the above-mentioned space j.

The other two pulleys 7d and 7e are arranged in the same way at a higher position than the pulleys 7a, 7b and 7c.

Each pulley is assembled at idle on a T-bracket 70 secured to the chassis 8.

This laterally displaced arrangement of the pulleys is corrected by the fact that the cable 3 has several latch points on the cross bar 20.

This is particularly evident in Fig. 8, which shows that each space of the cable 3a is larger than the space of the cable 3b.

Each drum 5 is driven by an electric gearmotor 51 fixed to the chassis 8, the output shaft of which provides coaxial drive to the drum shaft 50.

The five motor-driven drums 5a to 5b are all computer or programmable controllers not shown here, including data relating to the desired display cycle, i.e., scrolling instructions and the frequency and display time for each poster. Is controlled by.

Of course, some posters may be displayed longer and / or more frequently than other posters, depending on the program.

In Fig. 6 only those systems related to the first two posters corresponding to the references a and b are shown.

The first poster 4a is in a hidden position and the strip 1a is wound on its receiving drum 5a so that the poster is in its upper position and visible to the viewer on the left side of the drawing through the pane 90. none.

In contrast, the poster 4b is in the operating position towards the window pane 90. Therefore, this can be seen by the observer.

The size of the window 9 ensures that various control system components, for example straps, cables and crossbars of the system which are generally inactive, cannot be seen through the window.

It can be seen from Fig. 8 that the size of the poster 4 drawn by dashed lines is much larger than the size of the window.

6 shows a diagram of detectors 92 and 93 for each acceptance or correct deployment for each poster.

Detectors 92a and 92b are located in the lower part of the window and detectors 93a and 93b are located in the upper part thereof.

These are standard detectors, for example optoelectronic or photovoltaic cells.

The deployment state of each poster can always be controlled by these detectors sending the appropriate signal to a microprocessor controlling the motor or an electronically programmable controller, thus ensuring accurate display operation.

As mentioned above, the poster and its support unfold evenly and flatly thanks to the feedback pulley acting on the expander cable.

In another embodiment, the poster and the support can be unwrapped tightly by merely adjusting the weight of the crossbar 20 with additional weight if desired.

One poster can be quickly replaced by another because of the acceptance of the previous poster and can be performed simultaneously at the time when the development of a new poster is hidden.

The device is well suited for innovative campaigns, and the message of a poster derives information that will be found in one or several posters later.

The poster used is made of a thin resilient material that does not tear or crumple, for example, paper or plastic film.

Of course, fastening systems other than fabric fasteners, such as clips, snaps or adhesive tapes, may also be used.

In order to facilitate the exchange of posters, display windows should be provided which can be easily removed or opened to allow access to the various poster supports.

Obviously, the size of this device will be suitable for the size of the poster to be used.

As an example, the width of the strip 1 falls in the range of 1 to several meters, and the drum 5 and the countershaft roller 6 have a suitable length.

The drill 5 may be made of aluminum having a diameter of about 60 mm.

The roller 6 should preferably be made of surface-treated aluminum to avoid leaving marks on the back of the poster and should have a diameter of about 30 to 40 mm.

The space j between the posters is about 15 to 30 mm.

The diameter of the feedback pulley 7 is about 80 to 100 mm.

A device of this kind can be used, for example, in a fixed structure assembled to the exterior of a building, or it can be housed in a panel mounted on any kind of support.

It may also be assembled in the advertising vehicle as illustrated in FIG.

This figure shows a van-shaped vehicle 100 having a driver's cap 103. The vehicle has side 101 and rear 102 panels equipped with poster display windows 9, 9 ′, respectively. As provided in the present invention, three display devices are arranged inside the vehicle, each of which is associated with one of the windows.

In the embodiment illustrated in Figures 10 and 11, the poster 4 shows a frame 400 that allows the poster positioned behind it to be shown. This may be a simple opening across a poster or transparent area. Thus, various parts of the poster will be seen through the window 400 depending on how far the strip 1 supporting the poster to be placed behind the frame poster 4 is unrolled. Thus, if a picture, message is printed on the rear poster so that they appear selectively in window 400, this may gradually change the displayed background as seen on the front poster.

In the example given in Figures 10 and 11, the window is a "speech balloon" that expresses what the advertising character thinks.

On the rear (hidden) poster are provided two messages, "OUI" and "NON", arranged at two different heights, which are when the poster at the rear is lowered (Figure 10) or partially raised ( Arrow H in FIG. 11 is suitable for appearing in speech buruns.

Naturally, several windows may be provided on the poster in front by two or more messages assigned to the windows on the poster in the back. Moreover, the messages are also pinned on one (or more) posters well laid out behind the scenes so that they can be easily recognized when the poster between them is fully raised.

In another embodiment of the device, a single plastic strip forms the poster and its elastic support. This includes a blank leader area wound on the receiver drum. The rest of the strip has a print, picture or other message for the display. They can be applied to the strips as appropriate, for example attached to the strips or printed directly. The heavy bar attached to the free end of the strip creates tension and allows it to return to the operating position. The ends of the bar are guided in runners perpendicular to the sides.
