Abstract:
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.
Abstract:
'HINGE WIH SETUP FOR AUTOMATIC FLATTENING AND EXPANSION SYSTEM, FOR ARTICULATION AND SUSPENSION OF VARIOUS ELEMENTS', which receives, besides internal wall segments (2) and (3) and peripheral wall segments (9) and (10), extensions (12) and (13), which fold themselves by its creases (11), closing between them in the interior of the laminar body (1), keeping strongly tensed after receiving anchoring of elastic lace (16). Through the setup with the extensions (12) and (13) the hinge (1) gains self-articulation from its laminar body. According to the design, the hinge (1) can be adhered by its adjacent wall segments between the static surface and the element to be moved, for articulation from the static point. The hinge (1) can be adhered by its opposing wall segments between the static surface and the element to be moved, for its suspension in 'pop-up' system. The hinge (1) can be adhered by its adjacent wall segments between two faces of a creased element (to be moved), so that these two faces can be simultaneously articulated between them, opening or closing this element.
