Abstract

The display panel according to the present invention consists of: an area for vertical storage of the posters, elements for holding the posters equipped at their extremities with lugs, a system for pulling the posters along, a poster exposure area and a system for gripping posters in the storage area, able to pick up any posters. This gripping system consists: of a unit 23 capable of moving, on the one hand, under any type of lugs of holding organs 10b of the posters 11, by virtue of the use of sliding rails 13, 14 and, on the other hand, of pushing out the poster 11 under which it is situated by a vertical translational movement by virtue of a guide rail 16 and a cam 8 associated with a link rod 5.

Description

 The present invention relates to advertising display systems, or more generally information, scrolling posters. These systems are generally in the form of parallelepiped-shaped panels, which can be arranged on walls, pedestals, or integrated into urban furniture, inside buildings or outside visible from public roads for example .

Current advertising display or billboard information systems operate roughly according to two principles:
i '> The scroll is on a continuous poster strip.

20> Scrolling on a set of separate posters
usually stored vertically.

 In the first case (French patents: Neh7522693, Ne '8804239, etc.) except for all technical considerations specific to the drive systems of the panels, the problems lie mainly in the use of a continuous poster band difficult to to manufacture, to put in the panel, to unload, to reuse, and whose scrolling posters are only in a sequential manner, hence a lack of flexibility and ease of use.

 In the second case (patents: EUA N-2135207, Garlic N0 24o'230, Ang N + 7686 of 1913, Ang N 2231063, Euro N 0287268) the posters are stored vertically and are in the form of cards, double sheets, sheets printed on both sides, etc ... which is not the current practice of potential users. on the other hand their operation is done in a purely sequential manner.

 To remedy these types of problems of the prior art, the present invention relates to a new technique of exposure of distinct posters, more adapted to the user environment and whose operation is done in a dynamic way it is & say in a way not only sequential.

 The movable sign display panel according to the present invention comprising: - A poster storage area in a vertical manner.

- A poster exhibition area located on one of the faces of the
sign.

.- Holding devices in horizontal position, for each of
posters, constituted by a sort of truss attached to the
upper horizontal part of the poster, finished at both
extremities by kinds of spurs, even to support,
guide and train the poster through the
beam7 - A gripping system for posters in the storage area,
to a training area.

- Training systems, consisting of two organs
synchronized, arranged on both side edges of the panel
to transport the poster released by the system of
gripping towards the exhibition area and bringing it back by
continued to the storage area.

Characterized in that the gripping system is constituted:
on the one hand, by two synchronized, so-called selection members, arranged on the two lateral edges of the panel, and even to position each under one of the two lugs of one of the holding members of any poster stored, a block sucseptible to put, protrudes the pin under which it is located and therefore the whole: holding member - poster
- Secondly, by two synchronized bodies, said transport, arranged on both side edges of the panel and sucseptible to collect the assembly: holding member - displays projecting through the two pins and bring it to the training organs to be exposed.

 We will describe in more detail, hereinafter indicative and not limiting: a schematic operating mode, an embodiment of the gripping system, a complete embodiment of the panel, as well as several improvements in level, gripping, training and maintenance .

In Figure 1, we can see, the different phases of
moving a poster according to a schematic path arrow. The
posters are stored vertically in the storage area (B), the
gripping system (A) is able to select any
what displays in (B) and send it in the system
closed loop training device (C). Poster is on display
in the exposure zone (D> and subsequently reduced from (D), by the
drive system (C) in the storage area (B).

 Figures 2, 3 and 4 show the various elements allowing the operation of the system and serve as some kind of reference figures.

- The piece (1) constitutes the base or support of the system.

- The piece (2) constitutes the driving element, in the form of a loop
closed, it can be a strap, a chain, etc., guide in
its displacement by the piece (6). In order to
simplification of explanations, the catch system
poster holding devices by (2) will not be
detailed for now.

- The piece (3) is a kind of drum, free in rotation by
report to (7), she accompanies the poster during her move.

- The piece (4) constitutes the transport element, it is a kind of
disc with a prominent open part that comes to take
the poster projecting and brings it by rotation with respect to
the axis, towards the drive loop (2). In order to
simplification of the explanations, its rotation will be
studied later.

- The piece (5) is a kind of connecting rod, flat shape, even
to perform a vertical translation movement.

- The piece (6) is a disc, which is according to the piece (2) a pulley, or
a pinion.

- The piece (7) is a tree which constitutes one of the two main axes of the
failure - The piece (8) is free to rotate relative to & (7) and from a
cylinder excenter constitutes a cam.

- The piece (9) is part of the base (i), it constitutes an organ of
support for the pins of the support members (10)
posters (11) in the storage area.

- The pieces (10) constitute the poster holding devices,
they consist of beams, provided at their ends
of cylinders constituting the pins, able to support
guide and train the poster through the
beam.

- The pieces (11) constitute the posters.

- The piece (12) is a pin secured to the connecting rod (5). It ensures
thanks to its displacement in a groove of (1), a good
vertical translation to the connecting rod (5).

- The piece (14) is a kind of curved rail, axis identical to (7>,
sucessible from this move in rotation with respect to (7), in
a groove constituted by parts (i) and (15). She has a
denture on its lower face, it is provided with a hole to
one end thereof adapted to receive a screw (17>.

- The piece (13) is identical to (14), it has the same radius of
curvature but its teeth are arranged on its upper part.

(Parts (13) and (14) may also be in the form of
discs or disk sectors.) - The crescent-shaped piece (15) is integral with (1) and
keeping both rails (13) and (14) in place in their housing
respective.

- The piece (16) constitutes a guide rail in translation for the
piece (23), it is held at the rails (13) and (14) by the screws
(17) and (18) which leaves it free in rotation - The parts (17) and (11) are screws fixed in (13) and (14).

- The parts (19), (20), (21) and (22) constitute with (13) and (14) a
gear train.

- The piece (23), translated in relation to & 6), by (5)
constitutes the projecting block.

- The piece (24) is fixed relative to (i) and allows the ejection of
pins of (2) and thus the ejection of the whole body of
hold - displays to the storage area (see Figure 12 and
13).

 It will be conciliated in the following explanations, that the different movements are common to the two sets of systems each arranged on the two lateral edges of the panel and are synchronized. The study of the operation of the different systems can thus be reduced to the study of a single set arranged on one of the lateral edges.

 Figures 5, 6, 7 and 8 illustrate the operation of the protruding system. At rest, Figure 5 and 7 the block (23) is in the lower position, has under the pin of the leftmost poster in the panel. When one wants to send this poster to the exhibition, one turns the cam (O of a half turn, this one then drives in vertical translation from bottom to top the piece (5>, which in its movement makes slide the block (23) in the guide rail (16>, the block (23) in its stroke then drives the lug of the holding member disposed above it, the poster assembly is then raised (Figure 6 and 8), the piece (4) has no more than between being rotated by another movement so that its protruding part (FIG. 2) grasps the lug of the holding member and carries the poster towards the control system. It is then sufficient to rotate the cam (8) another half turn to return it to the initial position (Figure 5 and 7).

 Figures 9, 10 and 11 illustrate the selection system.

When one wants to expose a poster, it is positioned under the lug of its holding member, the block (23), to do this, it actuates in rotation the shaft {19ut which, on the one hand, the curved rail (13) via the gear wheel (20) and the curved rail (14) through the gear train formed by the gear wheels (20) and (21). The rays of the pitch circles of the toothed wheels (20) and (21) are calculated in such a way that the two rails (13) and (14) move in the same movement, this allowing an always parallel and vertical displacement of the rail guide (16) .The shape of the piece (5) in an arc is such that it is always in contact with the piece (23) and thus sucseptible to slide in the guide rail (16) and this whatever the position of the latter. The passage from Figure 9 to Figure 10 is therefore by rotating the shaft (19) in the opposite direction of clockwise. In the position of FIG. 10, to expose the poster, it is sufficient to resume the previously described cycle of protruding and transporting to the driving zone, which is independent of the position of the guide rail (16), (figure 5, 6, 7 and 8 with the piece (16) on the right).

 FIG. 12, which is a general and front view of the panel, makes it possible to locate the two sets of symmetrical synchronized systems, each arranged on the two lateral edges of the panel, the two lower drive systems have been added, they consist of two drive discs similar to (), and a similar drum ss (8), as well as several holding struts.

 Figure 13, is a general and lateral view of the panel, it corresponds to Figure 1 schematic, we can see: the two lower drive systems, the shaft (in), which ensures the synchronization of the two selection systems and an example of a moving poster in the training system.

 FIG. 14 illustrates an exemplary drive of the transport disk (4). In this example, it is considered that the shaft (7) is fixed relative to the base (1). the disc (25) is integral with the shaft (7), thanks to a key (30). The transport disc (4) incorporates an inner gear wheel. The drive disc (6) incorporates an external gear wheel. The assembly: (4), the two toothed wheels: (26) and (2Q), and (6) then constituting a gear train.

When the drive disk (6) rotates, it drives the transport disk (4) at a lower speed. In the gripping cycle, when the lug is protruded, it is grasped by the transport disk (4), which brings it to the periphery of the drive disk, which seizes it in turn. the interest of this reduction of speeds is to distribute the shocks of a brutal acceleration in the case where the drive disk rotates at a constant speed on the one hand, and on the other hand to avoid the possible conflict of the two parts prominent seizures of the lugs. it is also possible to consider a slowing down of the training system, and the use of two parts of non-conflictual seizures (recessed - prominent), in this case the drive disk (6) and the transport disc (4) can in addition coupled by a rigid liason.

 Figure 15 illustrates an example in which the system (2) is able to control certain body of the gripping system. The drive system (2) is provided with prominent control members (32). In FIG. 15, the protruding control member (32) will rotate the cam (18) through the element (31) integral with the latter. This example of moving the cam (8) can also be used to rotate the transport disc (4). In this case the control members (32) should be judiciously distributed on (2) so that there is a good order of movements.

 Figures 16 and 17 illustrates in different plan directions, an example of a drive system. A protruding piece (33) is fixed on the drive member (2) which may be: a chain, a belt, etc. The grasping of the pin is done by the interieur of the closed loop that constitutes the training system. The drive disc is then hollowed out to allow the passage of the lug of the poster holding member.

 Figures 18, 19 and 20 illustrate in different plane directions, examples of connections: holding member - displays.

In this case, the holding member (10) of the posters (11) permanently resides inside the panel. The holding member (10) and the poster (11) are able to join or separate by the use of a liason by hooks (Figure 18), perforation of the poster (Figure 19). ), or by rail (Figure 20). This type of liason removable can reduce the short relative to each poster (1 (he).

 Of course, the invention is not limited to the examples described and shown; it is capable of numerous variants accessible to those skilled in the art depending on the intended applications and without departing from the spirit of the invention.
