<p>The invention concerns a support comprising at least one panel (2) made of substantially rigid and collapsible material including a display surface (3), return and stressing elastic bands (44) for dishing the display surface of the panel and a plurality of inserts (18-20) for maintaining the convexity of the display surface of the panel, countering the stressing rubber bands, and whereof the action is exerted discretely distributed along said display surface of the panel. The inserts (18-20) are equal in length to the distance between the two side edges (8, 9) of the panel (2), when it is dished, said panel being extended by two series of side flaps (12, 13, 14, 15, 16, 17) designed to form two series of dihedrals for receiving the inserts, the rubber bands (44) co-operating with the inserts and the flaps (12-17) and exerting, additionally to their horizontal stressing force, opposite vertical forces (49. 50) to maintain the inserts heightwise when the display surface is dished.</p> |
