Abstract:
1. A quick-opening door intended to open or close a bay made in a partition, comprising: a support structure including two vertical jambs surmounted by an electromechanically driven shaft, each of the vertical jambs having an outer planar bearing surface and a slideway, a flexible curtain moveable between a closed position in which the curtain closes the bay and an open position in which the curtain clears an access to the bay, the curtain incorporating at least two transverse reinforcing bars equipped at each of their ends with a crank-shaped tip engaged in the guiding slideway of each jamb, wherein the door has at least one transverse section of the curtain delimited by two transverse reinforcing bars and comprising two panels connected together by a hinge, each panel being formed of at least two strips of flexible material between which there is inserted a layer of material stiffening, weighting and insulating the panel so as to maintain the transverse section bearing upon the planar surface of each jamb, and wherein the crank-shaped tips of each transverse reinforcing bar allows the curtain to be guided over a guide plane defined by the slideways of the jambs in which the crank-shaped tips engage, the guide plane being offset from the plane of the curtain defined by the outer bearing surfaces.
