<p>The invention concerns a collapsible tilt-up door comprising a panel mobile between a closed position wherein the panel closes an opening (21) defined by two side edges and a top edge (20), and an open position (13) leaving said opening (21) free. From the closed position (14), the door panel tilts over by rotation (15) being driven by one or two horizontal halfshafts at mid-height, and is then moved by vertical translation upwards (17) into the proximity of the top edge (20). Thus the number of guide rails required for the door movements is considerably reduced, thereby enabling a collapsible tilt-up door to fit into a transparent structure such as a collapsible telescopic housing (1) comprising a series of arched modular elements (2-7) capable of being telescopically nested and made of transparent material such as a swimming pool cover.</p> |
