Abstract

A series of posters or similar panels (4) are attached to individual support sheets (1,2) of flexible material wound at least partly around a drum (5). A control system allows unwinding of the sheets from the drum such that the poster appears in a selected position, e.g. behind a display aperture or window (9). A series of posters may be mounted in slightly varying positions, such that their display positions are in planes (a-e) slightly differently spaced relative to the window. Movement of the support sheets and posters is controlled by traction cords wound around drive pulleys (7), and the posters are secured by transverse bars and lateral fastening strips of the support sheet. <IMAGE>

Description

Description: TECHNICAL FIELD The present invention relates to an apparatus for selectively and individually displaying posters by sequentially arranging posters from a plurality of posters behind a display window.

Fields of application of the device include advertising areas and road signs and information postings.

The device can be used to modify the posting message (or other display) on a fixed installation.

The device can also be used in advertising vehicles with display windows for advertising messages on the side and / or rear of van-type vehicles.

In this type of device, multiple posters are placed end to end on a flexible support to form a single elongated strip.

The long belt may be an endless belt as disclosed in, for example, French Patent Publication Nos. 1051852, 2579810, and U.S. Pat. No. 15,30,888.

In another possible embodiment, French Patent Publication No. 269239.
Publication No. 5, Publication No. 2152012, and International Publication WO / 9203813
As mentioned in the publication, a relatively short strip is wound around the drum at one end.

The long strip scrolls along the front surface of the display window.
This band is positionally controlled and driven so that the selected poster is directly behind the viewing window, thereby making it visible to the viewer, or in the case of an advertisement, the public.

In the first four publications mentioned above, such a display device is mounted on a propaganda vehicle.

The control of the display order can be easily managed by a programmable controller, that is, a computer. Appropriate control means, such as a photoelectric sensing cell and / or a mechanical detector, connected to the device ensure the correct operation of the device.

In the existing device, a plurality of posters are single and are displayed in a predetermined order, that is, each poster is displayed in the display window in that order.

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

That is, if it is necessary to successively display two posters that are not adjacent to each other in sequence, one or a plurality of posters between them must be scrolled as blank display behind the display window. This creates an objectionable display when the poster is in motion. Further, the blank display partially wastes the entire display time.

It should be noted in this respect that the contract between the advertiser and the client can specify that the display cycle is changed for each poster. Therefore, each poster is given a certain number of views and times, which may change over time.

Especially when the idea of a plurality of posters is connected, as in the case of a progressive advertising campaign, the order of poster passage may be set.

These demands for ordering are difficult to fit in the current state of a series of posters that are tethered together.

French Patent Publication No. 388854 entitled Luminous Advertising Device is a display that includes a set of screens (carrying advertisements) that vertically hang multiple parallel panels so that they can be displayed one after another in the same space. Corresponds to the device. In this case, the poster is stored by being wound up on a roller located above the device. A plurality of such rollers are driven by a single drive shaft via a motion transmission mechanism, which starts the descent of the next screen while one screen is being wound, and thus all The screen display operation is performed in a predetermined order.

That is, in this light-emission advertising device, a plurality of advertisements are only displayed in a predetermined and unchanging order.

The present invention is intended to solve the above problems,
It is an object of the present invention to provide a display device of the type described at the beginning, which can freely select a desired poster display not only in the display cycle and time but also in the display order.

The display device according to the present invention makes it possible to selectively display various posters by arranging a poster in order from a series of posters behind the display window.

As in the device described in French Patent Publication No. 388854, each poster is fastened to a flexible support that can be at least partially wound onto a rotating drum, and the posters are viewed from a viewing window. A controller is provided for selectively aligning the invisible storage position and the operating position aligned with the viewing window to position the posters in separate parallel planes at small intervals.

In order to solve the above-mentioned problem, in the poster display device according to the present invention, each poster is individually and separately displayed by individually and selectively displaying a plurality of posters behind the display window. Each flexible support is fastened to the flexible support on the back side of the poster, each flexible support being individually at least partially rollable onto a separate rotating drum, and each flexible support to each rotating drum. A control device is provided for selectively aligning each poster with a storage position invisible from the display window or an operating position aligned with the display window by controlling the winding of the poster, and each poster is displayed in the operating position. Behind the windows are located on separate planes spaced apart from each other and parallel to each other, with each poster and its supporting flexible support in the operative position when in the retracted position. It is configured not to interfere with the display of the star, and means for automatically applying a traction force in the feeding direction from the rotating drum to each flexible support to automatically return each poster to the operating position individually, A plurality of forward / reverse rotating electric motors that individually drive each rotating drum against the traction force by the automatic return means, and each electric motor that individually and selectively moves each poster to the storage position or the operating position. And a programmable controller that operates.

It goes without saying that the display device of the present invention is configured so that when the poster is in the storage position, the member supporting the poster and the poster itself do not interfere with the display of the poster in the operating position.

Further, listing a number of additional, non-limiting, and preferred features of the present invention, the flexible support is rollable around a rotating drum and extends across the height of the viewing window by a pair of side edge straps. A pair of side edge straps are connected by a transverse bar for fastening the poster, and the poster is detachably attached to both the transverse bar and the edge of the flexible strip. The device includes means for tensioning the flexible strip, the transverse bars being attached to a pair of extension cords each wound on an automatic rewinding pulley, and the flexible strip at the exit of the rotating drum. Passing over the intermediate guide roller, this intermediate guide roller is gradually reduced in diameter toward both ends so as to center the strip well, and the outer diameter is slightly increased in the central portion, and the display window is a vertical surface. Meanwhile, the rotating drum and the intermediate guide The ruler has a horizontal axis and is arranged parallel to the main surface of the display window in the box at the top of the display window, in which case the rewinding pulley preferably has a horizontal axis and is in the box at the bottom of the display window. Is located in.

The invention also provides an advertising vehicle equipped with at least one display device as specified above.

Other features and advantages of the present invention will be apparent from the following description showing the preferred embodiments and the accompanying drawings.

FIG. 8 is a scaled side view corresponding to the lower half of FIG.

FIG. 9 is a sketch drawing showing an advertising vehicle equipped with some display devices according to the present invention.

FIG. 10 is a perspective view similar to FIG. 1 showing two support structures for adjacent posters with both posters lowered to expose the front poster to the display window frame.

FIG. 11 is a perspective view similar to FIG. 10 in a state where the poster on the rear surface side is partially raised.

In the illustrated embodiment, the display window has a vertical layout and the apparatus includes five posters which are alternately selectively positioned behind the display window.

Of course, 5 is for illustration only,
It can be any number of posters.

FIG. 1 shows a flexible support that supports one of the posters.

This support includes a flexible strip 1 such as a thin oil cloth,
It is composed of a pair of side edge straps 2 and a pair of side edge extension cords 3. The strip 1 forming the upper part of the support is wound around the outer circumference of a cylindrical rotary drum 5, the shaft 50 of which is the horizontal axis. This shaft is parallel to the vertical surface of the display window (not shown) in normal times.

Driving means described later can rotate the drum 5 in forward and reverse directions as shown by a double-headed arrow F in FIG.

The strip 1 passes through an intermediate guide roller 6 whose horizontal axis is parallel to the axis of the drum 5. The counter operation by the intermediate guide roller occurs at about 45 degrees, and the strip material between the roller 6 and the drum is substantially horizontal. As shown in FIG. 4, the roller 6 has a taper shape with a low inclination, and its central portion has a maximum outer diameter.

At both ends of the roller 6 corresponding to the taper-shaped small-diameter portion, guide collars are provided as guides for both side edges of the strip.
60 are provided. These guide flanges 60 are also tapered so that the diameter thereof is reduced inward, thereby preventing the strip from deviating to the side. The loose taper of the roller 6 provides automatic alignment of the strip and good centering in both the winding and unwinding directions.

The edges of the strip 1 are extended by the side edge straps 2 on the side not wound on the drum 5, which side edge straps are made of non-stretch fabric. These straps 2 can be attached to the strip 1 by any suitable means such as bonding or riveting. The free ends of the side edge straps 2 are connected to each other by transverse bars 20.

As shown in FIG. 2, the transverse bar 20 is composed of a pair of narrow plates 21 and 22 each having a chamfered edge, and the ends of the side edge straps 2 are narrowed between the thin plates.
A plurality of rivets 23 that fit the 21, 22 and the strap 2 are fixed together.

The extension cords 3 respectively connected near both ends of the transverse bar 20 extend downward and are wound around the pulleys 7. Each of these pulleys 7 is provided with a pair of disc-shaped guide flanges, and a groove for winding the extension rope is formed between the flanges (see FIG. 7).

These pulleys 7 are standard automatic rewinding pulleys having a built-in coil spring that constantly urges the extension cord in the direction of winding it into the groove, whereby tension is applied to the extension cord as indicated by arrow T in FIG. I'm working.

The above support holds the poster 4 so that it can be removed without difficulty.

In the illustrated embodiment, the widely sold "Velcro
™ loops and hook-and-loop cloth fasteners are used to hold the poster.

In the case of this embodiment, one of the two cloth elements of the cloth fastener, specifically, the hook side cloth, is provided on the front edge 10 and the transverse bar 20 of the flexible strip 1 on the side facing the display window. The element is attached.

The other cloth element, specifically, the loop side cloth element is attached to the back surface of the poster 4 at a corresponding position.

Thus, the poster is easily attached to the support by simply pressing it against the strip. When installed,
The poster will fill the space corresponding to the rectangle formed by the two straps 2, the strip edge 10 and the transverse bar 20.

The printed display 40 on the poster is positioned so that it will properly emerge from a display window (not shown in FIG. 1) that is slightly smaller than the poster.

Comparing FIGS. 1 and 3, it can be seen that the poster is displayed on the vertical surface when the drum 5 is rotated in the direction in which the strip is unwound, in which case the poster is attached by the rewind pulley 7 during unfolding. It is brought into a state of being pulled by pulling by the stretched rope 3 which is urged.

When the drum 5 is rotated in the opposite direction, the strip 1 is almost completely wound around the drum 5 and the transverse bar 20 moves to the upper limit position above the level of the display window. The poster is now bent backwards on the intermediate guide roller 6 into the storage position. In the upper limit position, the both side edge straps 2 are laterally guided by the guide flange 60 of the roller 6.

FIG. 5 shows how to set five poster supports in a device as described above.

In this figure, reference numeral 9 indicates a display window, and this display window includes its frame 91 and a transparent panel 90 such as a glass plate.

The device includes a machine base 8, which in particular comprises a front panel 82 holding the display window 9, the box 80 and a lower box 81.

In the upper box 80, five rotating drums 5 and five guide rollers 6 are incorporated. Further, five rewinding pulleys 7 are arranged in the lower box 81.

Each of these parts is positioned so that each of the five flexible supports has a display operation position on any of the vertical planes a, b, c, d, and e parallel to the glass plate 90. Each of these vertical surfaces is regularly spaced apart from each other by forming minute gaps j. Similarly, the first vertical surface a closest to the display window has a minute gap k from the glass plate 90.

A plurality of intermediate guide rollers 6a, 6b in the upper box 80,
The 6c, 6d, 6e and the rotating drums 1a, 1b, 1c, 1d, 1e are arranged as close as possible and without any contact with the poster support or the poster itself.

Similarly, each pulley 7a, 7b, 7c, 7d, in the lower box 81
The position of 7e is shifted to avoid interference with each other's extension lines, and at the same time, the size is maximized.

In particular, in the embodiment shown in FIGS. 5 and 7, the five pulleys on each side of the device are separated into two groups.

Pulleys 7a, 7 related to the first to third posters
The axes of b and 7c are located in the same horizontal plane, but they are offset from each other in the left-right direction and from the front side to the rear side of the display window so as to form the above-mentioned gap j.

The other two pulleys 7d, 7e are arranged at a higher position level than the pulleys 7a, 7b, 7c in a similar manner.

Each pulley is assembled to a T-shaped bracket 70 fixed to the machine base 8.

The lateral displacement of the pulleys is compensated for by the extension lines 3 having different connecting points on the transverse bar 20.

This is clearly shown in FIG. 8, and it is shown in FIG. 8 that the distance between the left and right extension cords 3a is larger than the distance between the extension cords 3b.

Each rotary drum 5 is driven by an individual electric gear motor 51 fixed to the machine base 8, and the output shaft of the motor provides coaxial drive to the shaft 51 of the rotary drum.

The total of five motors 5 that drive the rotating drums 5a to 5e are
It is controlled by a programmable controller (not shown), that is, a computer, and this computer is provided with information regarding a desired display cycle, for example, the order of scrolling and display, and a cycle and a display time for each poster.

It goes without saying that some posters may be displayed longer or more frequently than others according to the program.

FIG. 6 shows the essential configuration of only the first two posters corresponding to the reference signs a and b.

The first poster 4a is in the storage position and the strip 1a is wound on its drum 5a, so that this poster is in the upper limit position and is not visible through the glass plate 90 to the viewer on the left side of the drawing.

On the other hand, the second poster 4b is in the display operation position,
It faces the glass plate 90. Therefore, it is in a state visible to the viewer.

The size of the display window 9 prevents the straps, extension cords, and transverse bars from being seen through the window when not operating.

In FIG. 8, the size of the poster 4 shown by the alternate long and short dash line is sufficiently larger than the size of the display window.

Detectors 92a and 92b are arranged in the lower part of the display window, and detectors 93a and 93b are arranged in the upper part of the display window.

These are standard type detectors such as photoelectric detectors or photocells.

The unfolded state of each poster can be controlled by these detectors at all times, and appropriate signals are sent from these detectors to the microprocessor or programmable controller controlling the motor so that the correct display operation is performed.

As mentioned above, each poster and their support
It is always stretched flat by the action of the rewinding pulley that acts on the extension cable.

In another variation, each poster and support can be tensioned by simply adjusting the load on the transverse bar 20 with additional weights as needed.

The storage of the displayed poster and the deployment of a new poster into the display window are possible instantly within the time that the display window is masked, and it is therefore possible to replace the display poster with another quickly.

The device is particularly useful for conducting progressive campaigns in which poster messages in turn lead to informative information on subsequent posters.

The poster used is made of a thin flexible material such as paper or plastic film that is not easily torn or wrinkled.

Of course, a fastening method other than the cloth fastener, such as a clip, a snap, or an adhesive tape, can also be used.

In order to speed up the exchange of posters, an openable display window and a glass plate that can be easily removed to allow access to each poster support may be prepared.

It goes without saying that the size of the device is adapted to the size of the poster used.

To give a specific example for reference, the width of the strip 1 is 1 m to several m.
And the rotary drum 5 and the intermediate guide roller 6 have lengths adapted to this range.

The rotating drum 5 may be made of aluminum and have a diameter of about 60 mm.

The guide roller 6 is preferably made of surface-treated aluminum so that no marks remain on the back of the poster. The diameter of the guide roller is about 30 to 40 mm.

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

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

This device can be installed in the front of a building,
It is applicable to fixed structures such as installed in panels mounted on various types of support structures.

The device may also be mounted on a promotional vehicle as shown in FIG.

FIG. 9 shows a van-type vehicle 100 including a driving cabin 103. This vehicle has a display window 9 for posters.
It has both side panels 101 equipped with and a rear panel 102 equipped with a similar display window 9 '. Attached to each display window are three display devices similar to the device according to the invention described above arranged inside the vehicle.

In the embodiment shown in FIGS. 10 and 11, the poster 4 displays a small window 400 for showing another poster located behind it. This window can simply be an opening through the poster or a transparent part. As a result, by adjusting the feeding amount of the belt material that supports the poster to be positioned behind the poster 4 with the small window,
Various parts of this poster behind can be seen through the window 400. Therefore, by printing patterns and messages on the poster behind, it is possible to selectively display them on the small window 400, and the display scene can be gradually changed as the display on the poster in front. .

In the examples shown in Figures 10 and 11, this window is a "speech balloon" and describes what the advertising character thinks.

The poster behind has two messages "OUI" and "NON" at different heights, and these two messages are when the poster behind is lowered (Fig. 10). And adapted to appear in the balloon when slightly elevated (arrow H, FIG. 11).

Of course, you can have more windows on the poster in the foreground and two or more messages that fit them in the poster behind. Furthermore, it is possible to place the message on one (or more) posters located further behind so that the message can be seen when the posters located between them are completely rolled up.

As another modification of this device, a single plastic strip can serve as both the poster and its flexible support. In this case, the single plastic strip would include a blank leader portion that would be wound on a drum. The rest of the strip is provided with prints, graphics or messages to be displayed. These are formed on the band material by an appropriate method such as sticking or direct printing. If a weight bar is attached to the leading edge of the strip, it can be used for tensioning the strip and returning to the display operation position. In this case, both ends of the weight bar can be guided by the vertical grooves on both sides of the display window.
