  The posters 2 placed on the display panel 1 are, in the embodiment considered, of square or rectangular outline, limited by an upper horizontal border 10, a lower horizontal border 11 and

  two side edges, vertical 12.

  By border we mean here the area of poster 2

  adjacent to its free outer edge.

  A poster 2 thus comprises a main printed part 13, made of paper, therefore having a certain flexibility and capable of being deformed and more particularly rolled, rolled up or folded. Along three of its four free edges, the part 13 is provided with a band 14, overlapping on the part 13 and

  secured to it, in particular by bonding.

  The three strips 14 are intended, when the poster 2 is in place on the display panel 1, to

  form edges 10, 11 and 12 respectively.

  A strip 14 is produced according to the embodiment considered here in a flexible plastic material but

  inextensible and having a great hold.

  The bands 14 forming the edges 10, 11, 12 are provided with eyelets 15 regularly arranged along their length.

2743178

  In the embodiment considered, there are provided several posters 2 placed one beside the other, horizontally, but independent of each other. These posters 2 are all supported by the support means 9. In this case, a poster 2 is located opposite the window 8 while the other posters 2 are hidden from view relative to this window 8. The panel 1 therefore comprises also drive means 16 support means 9 so as to ensure the movement of

posters 2.

  This scrolling is preferably discontinuous, that is to say that the drive means 16 are stopped for a certain time or the poster 2 facing window 8 can be seen by an observer. Then, the drive means 16 are active to change the poster

And so on.

  However, also falls within the scope of the invention the case where the posters 2 scroll continuously,

  the drive means 16 being arranged accordingly.

  In the embodiment considered, the scrolling of

posters is horizontal.

  In the embodiment considered, the support means 9 comprise in combination with the first means 9a and a

pair of second means 9b.

  The first means 9a ensure the maintenance of

  poster 2 along its upper horizontal edge -

  i.e. at the location of the upper horizontal border 10.

11 2743178

  The second means 9b ensure the maintenance of

  poster 2 along its two vertical edges, that is

  say at the place of the vertical lateral borders 12.

  The support means 9, 9a, 9b are arranged so that the poster 2 can be maintained without risk of untimely stalling, the maintenance being nevertheless

  removable, when desired.

  The first means 9a firstly comprise a support member 17, elongated horizontally parallel to the posters 2 and to the border 10, being in the form of an endless chain or equivalent, forming part

  also drive means 16.

  The endless chain 17 is slidably mounted in a guide member 18 and it is engaged with toothed pinions 19 mounted wedged on the axis 20 of guide rollers,

  diversion and return of posters 2.

  The pinions 19 are placed towards the extreme part

upper free axis 20.

  The axes 20 are arranged vertically.

  In the embodiment under consideration, three pairs of rollers 21 are provided, namely a pair of front rollers 21a, a pair of rear rollers 21b), and one

pair of middle rollers 21c.

  The front rollers 21a are located near

from window 8.

12 2743178

  2lb rear rollers are located nearby

  of the large face 7 opposite the window 8 considered.

  As for the middle rollers 21c, they are located in the vertical median plane of the panel 1. The front rollers 21a and the rear rollers 21b are spaced apart and located near the walls

vertical 6a of the belt 6.

  The median rollers 21c are on the contrary spaced from these vertical walls 6a and close to the horizontal axis

belt 6.

  In case panel 1 has two windows

  8 on both sides, the arrangement and symmetrical.

  One of the rollers 21 has wedged on its axis a motor or geared motor. In addition, one of the rollers, in particular of the pair of median rollers 21c, is mounted movable horizontally parallel to the plane P so as to accommodate differences in length or

poster voltage 2.

  The first support means 9a then comprise a series of lugs 22 rigidly fixed and transverse to the chain 17. These lugs 22 are regularly spaced from one another. They are

directed downward.

  At least part of the legs 22 is provided frontally with studs 23, arranged in projection and intended to pass through the eyelets 15 of the horizontal border

upper 10.

13 2743178

  The relative dimensions of the eyelets 15 and the studs 23 are such that their cooperation is made possible to allow the removability of the poster 2 but to prevent its untimely detachment. The second means 9b include two sets 9ba, 9bb, similar, placed back to back, located & close to each other, arranged parallel or substantially parallel to each other, connected to each other by a

  or elastic and flexible members 24.

  An assembly such as 9ba or 9bb is placed vertically with respect to the posters 2. It firstly comprises a support piece 25, rigid, taking the form of a flat iron or a profile. The support piece 25 is fixed to the chain 17 and to another support member 26 extending parallel to the chain 17 but located at

  near the bottom border 11 of poster 1.

  The support member 26 may have the same general structure and shape as the chain 17. Its function is to carry the support pieces 25 in synchronism with the chain 17 so that the pieces 25 remain vertical, while

  being moved by the drive means 16.

  Each set 9ba, 9bb then comprises a series of studs 27 fixed transversely, frontally and projecting from the support piece 25, regularly spaced apart.

  from each other, directed to window 8.

  The two assemblies 9ba and 9bb are connected to one another by one or more elastic and flexible members 24 such as two flattened ribbons located at least towards the

14 2743178

  upper and lower end parts of the assemblies

9ba, 9bb.

  For the installation of a poster 2 as just described, the window 8 of the panel is opened, which gives access to the support means 9, these being presumed to be free at this time. poster, one can set up a poster such as 2 by making the eyelets 15 of the edges 10, 11 and 12 cooperate with the studs 23

and 27, respectively.

  This is done in three successive steps: - the installation of the eyelets 15 corresponding to the vertical lateral border 12 located upstream by

  relation to the direction of scrolling of the poster 2.

  - Then, that of the eyelets 15 corresponding to the upper horizontal border 10 and that of the vertical lateral border 12 upstream to the vertical border 12 downstream. - And, finally, the placement of eyelets 15

  corresponding to the downstream vertical lateral border 12.

  To remove a poster, we proceed in a similar but inverted manner: first the upstream side border then the upper horizontal border and finally the border

lateral downstream.

  The display panel also includes, enclosed in the housing, a positioning device and

removal of posters 2.

2743178

  Indeed, these being or being able to be of large dimensions and presenting, naturally, a

  certain softness, it is difficult to handle them.

  We will now describe this device more specifically. A pin 28 with a vertical axis, parallel or substantially parallel to the axes 20 of the guide, deflection and return rollers 21 is pivotally mounted on the

housing 5.

  especially on the order of or less than 90.

  In the inactive position, the pin 28 is housed in the free space open laterally to the outside limited by the poster support means 2, the drive means and the posters 2 themselves, defined by two guide rollers, lateral deviation and deflection, respectively front 21a, rear 21b and a median roller 21c close to the horizontal axis of the belt 6 of the

housing 5.

16 2743178

  In the active position, the pin 28 is located near one of the two rollers 21, respectively front

21a and rear 2lb.

  In the active position, the pin 28 is capable of removably receiving and driving in rotation a

  coaxial roller supporting the rolled up posters.

  To this end, the pin 28 includes a transverse support flange 32 of the poster winding roller. The pin 28 or its flange 32 comprises the centering means 31 and the setting in relative rotation 30 relative to the poster winding roller cooperating with the complementary means of said roller such as

pawn cooperating with a hole.

  The pin 28 is associated with torque limiting means 33 or soft rotation friction preventing the

  untimely pivoting of said pin.

  Another pin (not shown) coaxial with pin 28 is carried by the upper horizontal wall

of the belt 6 of the casing 5.

  The two coaxial pins are connected to each other or are able to be moved in synchronism between

their two extreme positions.

  The display panel may include removable means for holding a trunnion or the pair of

  coaxial pins in active position.

  In one embodiment, the pin carried by the upper horizontal wall of the belt 6 of the

17 2743178

  casing 5 is a hollow cylindrical part, such as a tube

coaxial with pin 28.

  The pin 28 is connected to the drive means 16 of the rollers 21 by means of an endless chain engaged with the pinion of the roller 21 near which

finds pin 28.

  - the initial free end transverse part of the poster 2 is removed from the support means 9; - Hanging said end portion to the poster support roller; - By means of a control button, the means 16 are put into slow motion, opposite to that of the scrolling of the posters when the panel is in service. During this step, the pin 28 is driven in slow speed on its axis by the drive means 16. A foot control of the operator (not shown) is arranged so as to ensure the slow start of the means of drive 16 of the rollers 21 and therefore a controlled winding of the poster 2 on its support roller as the poster is detached from the support means 9; - When the poster 2 is completely detached from the support means and the packed support roller, said support roller is removed from the journal; - the pin (s) is brought to the inactive position; - The drive means 16 are reset to normal by means of a main control button;

  - the side door of the casing 5 is closed.

  The operator's foot control (not shown) allows the operator to start the drive means 16 at slow speed or step by step, so that it is possible to stop the normal scrolling of the

2743178

  posters at any time without preventing change or

the removal of a poster.

  Indeed, the operator, by means of the foot control, will be able to correctly position a vertical border of the poster support means 9b relative to the

reel pins.

  In addition, the operator will be free to set up or remove a poster, perfectly mastering the unfolding or winding of the posters

  on the support roller, by the foot control.
