Abstract

The notice board comprises a flexible surface (11) to which the notices are fixed and a supporting frame. The flexible surface is held under tension by S-shaped springs which have a hook (10a) at one end allowing them to be attached to the frame and a clip at the other end with a circular groove which fits over a loop at the end of the flexible material.

DISPLAY DEVICE

  The object of the invention relates to the technical sector of signs, signs and other information display and advertising devices. Numerous fixed or mobile display means are known, such as panels on legs or with wall mounting, on which are positioned

  posters or the like, either permanently or temporarily.

  In the case of panels with variable or mobile presentation, the information is produced on a flexible surface, plastic film, canvas ... and is mounted on rollers driven by any motor means to be presented periodically on the front face of the panel, behind a glass, which, as we understand, involves a complex construction, therefore expensive and capable of

  breaking down thus removing all appeal to this type of presentation.

  According to the invention, it was desired to produce robust, economical and reliable display panels, capable of carrying a flexible surface, of information easily interchangeable, offering good solidity, perfect readability and

which is easily washable.

  For this, and according to a first characteristic, the flexible information surfaces are mounted in tension on their support frame by a plurality of tensioning means with elastic capacity, arranged to, on the one hand, be firmly but detachably secured to said flexible surfaces and, on the other hand, be removably connected to said support frame equipped with

this effect.

  According to another characteristic of the invention, the removable connection means with elastic capacity carrying the information surface are housed inside the support frame, the sectional profile of which is designed so that said frame is almost entirely hidden when the surface information is tense; said frame having for this a pivoting flap allowing the introduction of

  means with elastic capacity and ensuring the tightness and aesthetics of the panel.

  These characteristics and others will become clear from the rest of the

  In order to make the object of the invention more concrete, it is now described

  in a nonlimiting manner illustrated in the figures of the drawings.

  The display panel, referenced as a whole by the reference (PA) 1 0 includes a support frame (C) carried by a base (P) or arranged for

  be attached to a vertical surface such as a building wall. The framework-

  support (C) consists of four profiled elements (1, 2, 3, 4) having externally, on at least one of its faces, two U-shaped grooves (la, 2a, 3a, 4a), in which are mounted sliding two bars (5) i 5 intended to cooperate with angle assembly brackets (6), by means of screws (7) engaged in tapped holes (Sa) of the bars

(Figures 3, 4 and 5).

  The face opposite the grooves (la, 2a, 3a, 4a) is constituted by a flap (8) which is articulated by one end (8a), on a projection with circular profile (lb, 2b, 3b, 4b) established from of an angle of the elements (1, 2, 3, 4). An elastic member of the spring type (9) is hooked by its curved ends (9a) on projections (lc, 2c, 3c, 4c) and (8b) of the elements of the support frame and flaps, in order to constitute a hinge with spring (CR) to hold said flaps either

  raised position (figure 9), or in lowered position (figure 10).

  The end (8c) of the flap, opposite the hinge is curved outward to bear on a wall (ld, 2d, 3d, 4d) of the elements, wall

  extending diagonally from the top to the bottom.

4 2793059

  Near this upper part, the wall (ld, 2d, 3d, 4d) has a tongue (le, 2e, 3e, 4e) extending substantially parallel to the underside (If, 2f, 3f, 4f) of the elements. This tongue constitutes the removable connection means of the elastic capacity means (10) intended to connect in

  tension the flexible information surface and the support frame.

  For this purpose, the means (10) are made of a material with elastic capacity such as polyacetal and have the general shape of an S in section with a straight branch (10a) terminated by a hook (10b) for connection with the tongue (the, 2nd, 3rd, 4th). In contrast, the branch (10a) is extended by two inverted curved arcs (1 Oc, 10 Od) forming an S proper, then the second arc is extended by a generally triangular part (10e) extending from tilted way. The end of this part has a deep circular groove (10f) whose sides close and are largely rounded. This groove, which has a lengthwise conical profile, is intended to receive a loop (1 la) formed at one end of a flexible information display surface (11) which can be made of any material.

such as canvas, plastic film, ...

  As seen in Figures 7 and 8, to ensure a firm connection between the information surface (11) and the tensioning means (10), it suffices to engage the loop (1 la) in the groove (10f) and force fit a taper pin

  (12) with gripping projection (12a), inside the loop.

  To ensure perfect resistance in tension of the surface (11) on its frame-

  support, there is a large number of tensioning means (10) on each element of the support frame and, as seen in FIGS. 9 and 10, it suffices to pull on the surface (11), after having hooked the tensioning means ( 10) on

2793059

  tabs of the support frame, in order to obtain, by successive hookings opposite and laterally, a stretching of the tensioning means, therefore a tension

all-round.

  Note that when the information surface (11) is stretched over its frame-

  support (C), the latter is practically invisible due to the mounting of the tensioning means inside the profiled elements and the exit from the surface

  in the upper corner of said support frame.
