<p>Hinge with elastic element and tab adapted in cardboard display sands for assembly, flattening and automatic set-up systems, formed from a cardboard plate (1) with creases (2), (3) and (4) which mark the swinging segments (6), (7), (8), (9) and (10), forming a hinge (14) to be applied to display stands (such as display shelf, display-box, totem and other similar objects obtained from the central cardboard cutting and creasing design), operating through tension imposed by the elastic loop (15) anchored into the cuts (17) of a beveled tab (16) internal or posterior, positioned in the junction points of the adjacent walls (P) of the display stand (D). The hinge (14) works in clamping system, closing itself strongly tensioned during the display stand (D) flattening, for piling, transportation and delivery to the client, secured in an envelope. After delivery, the hinge (14) is opened by pulling offered by the loop (15), pushing forcefully the flattened walls (P) of the display stand (D), for its automatic opening and set-up.</p> |
