With a high performance door, preferably high speed door, for closing an opening (11), preferably in a wall (12) comprising a flexible curtain (13) to be wound and unwound on a shaft to open and close the opening (11) with a rigid bottom beam (15) attached on the lower end of said curtain (13) the risk from the bottom beam to the environment upon opening is reduced in, that the rigid bottom beam (15) comprising at least one flush side (20) at least almost flushing the curtain (13).

Systems and methods are provided for facilitating automated and manual segregation of internal areas within structures in response to active shooter warnings, or other triggering events. Embodiments may provide automated systems and methods, to facilitate simplified and automated (1) deployment of mechanized safety and/or security (bulletproof) curtains, including certain safety curtains comprising, or otherwise formed of, replaceable bulletproof and/or other penetration-resistant materials, and/or (2) actuation of mechanized safety and/or security (bulletproof) doors, to effectively segregate open areas and hallways in buildings. Exemplary embodiments may: (a) limit lines of sight of a perpetrator; (b) interdict bullet flight paths; (c) restrict or eliminate a perpetrator's freedom movement; (d) confine areas of detected explosive ordnance detonations or dispersal of contaminants; (e) provide a means of trapping/isolating a perpetrator; and/or (f) provide local safe havens in active shooter, gunfire, explosive detonation, contaminant dispersal, and like threat scenarios/situations.

A high speed roll door is movable between an open and a closed position at an opening of a building. The door includes a flexible curtain and a pair of side columns. Each side column provides an inner track to guide the curtain in vertical movement and restrain the curtain from lateral movement during deployment and retraction. The curtain further includes multiple cross bars supporting the flexible curtain from one of the pair of side columns to the other. Each of the cross bars further includes a first longitudinal bar sandwiching part of the curtain; and a second longitudinal bar pivotally connected to the first longitudinal bar. The hinge has an axis of rotation parallel to the first and the second longitudinal bars. At least a wheel is rotatably affixed to each end of the second longitudinal bar to engage the inner track of each of the side columns.

A high-speed rolling gate comprising a door leaf in the form of a flexible curtain, lateral guides in which lateral edges of the door leaf are received, and a drive which generates a driving force for driving the door leaf, wherein the door leaf has an elastically designed terminating element on a forward edge which is tensioned between the lateral guides by means of laterally applied transverse force components. The driving force of the drive engages on the terminating element of the door leaf and provides the laterally applied transverse force components for tensioning the terminating element of the door leaf and a tension force component substantially directed in the movement direction of the door leaf for closing the door leaf.
