Expansor applicable to self-exchangeable prismatic folding structure, prismatic self-transferable folding structure, and self-extendable folding exhibitor (Machine-translation by Google Translate, not legally binding)
Expander applicable to self-expanding prismatic folding structure, self-expanding prismatic folding structure and self-expanding foldable display. The expander comprises two laminar units (10, 20) partially superimposed and linked to slide guided one with respect to the other. The first laminar unit (10) comprises a first push edge (11) and a first hook configuration (121). The second laminar unit comprises two branches (20a, 20b) with respective second thrust edges (21a, 21b) and a second engagement configuration (121). In operative situation, the first anchoring configuration (121) is located closer to the second thrust edges (21a, 21b) than the second anchoring configuration (221), and the second anchoring configuration (221) is located closer of the first push edge (121) than the first anchor configuration (121). An elastic traction element (301) engaged in said first and second anchoring configurations (121, 221) displaces the laminar units and pushes the pushing edges (11, 21a, 21b) inwardly against edges of a self-expanding prismatic collapsible structure.
