A roll-up wall system including a frame having a longitudinal axis, a first roller disposed in the frame, a second roller disposed in the frame, and a tube disposed in the frame. A screen may be connected to the tube. The screen may be supported by the first roller and the second roller. Further, the screen may be movable between a first configuration and a second configuration. In the first configuration, the screen is rolled around the tube which is spaced a first distance from the first roller. In the second configuration, the screen forms a barrier adjacent the frame, and the tube is spaced a second distance from the first roller. The second distance may be less than the first distance. Also, the roll-up wall system may be an acoustic barrier which achieves a Sound Transmission Class rating ranging from approximately 31 STC to approximately 53 STC.

An automated fire or smoke curtain/blinds system (2) includes a pelmet or a hood (4) adapted to be mounted on a wall or top of a windowpane, at least one motor (6) connected to at least one curtain/blinds holding device (10) such that the curtain/blinds 5 holding device (10) rolls when the motor (6) is operated, at least two curtain/blinds holding device wherein each curtain/blinds holding device are connected by a shaft or ball bearing, a movable curtain or blind with width of at least 8 meters attached to at least two curtain/blinds holding device, a movable curtain or blind (14A) of a predefined width and at the end of which is a bottom rail (14B), wherein the movable 10 curtain (14A) includes an self-closing escape door (14C) embedded within coverage area of the movable curtain (14A), and a control panel (16) to control up/down movement of the movable curtains.

A high-speed roll-up door for separating two rooms at different temperatures includes a flexible curtain to close or open a passage of a room separation wall, which passage is delimited, by a portal structure which includes a pair of hollow rails for guiding the curtain. The lateral edges of the curtain have projections for engaging cavities formed between the successive teeth of gear wheels for controlling the movement of the curtain. In the open condition of the door the curtain is received in an upper shelter area axially delimited by two guide panels having specular guide paths. Each guide panel comprises has a seat of a respective gear wheel arranged away from the wall to which the portal structure is associated with, and under the guide panels is prepared a tray for collecting the condensation water present on the curtain, to allow the curtain to be collected entirely above the tray.

The window shade pocket system may comprise a pocket having an inside surface, a first wall and a second wall, wherein a roller shade is mounted within the pocket; and a first bracket removably affixed to the inside surface of the first wall of the pocket, wherein the first bracket retains a light source. The light source may include at least one of a light bulb, light bar, light strip, LED lighting or reflective device. The light source may be LED lighting that is modular or provides different colors over the window shade fabric. The light source may include a lens. The light source may be at least one of removeable from the first bracket or rotatable within the first bracket. The light source may be at least one of between the window shade and the window, or between the room and the window shade.

A barrier system includes a roll-up barrier comprising a plurality of slats hingedly connected, a guide system, and a drive system. Each slat of the plurality of slats includes a central portion having a first thickness, a top portion, and a bottom portion. At least one of the top portion or the bottom portion having a second thickness less than the first thickness. The top portion of each slat overlaps the bottom portion of an adjacent slat forming an overlapping region having the first thickness when the barrier is in a closed configuration. The guide system is configured to guide movement of the roll-up barrier. The drive system configured to transition the roll-up barrier between open and closed configurations along the guide system.

Examples herein describe systems and methods for securing an opening and disorienting an active shooter. A command device can send a deployment command to a zone in a building. In response, canopies in the zone can deploy a roll-up door made of Kevlar that electromagnetically locks shut. The canopies can include blindingly bright lights and deafening sirens that disorient the shooter. The doors can block off rooms or other areas of a school where children can huddle safely until the shooter is apprehended. Canopies without doors can also be used at some openings to disorient the shooter.

This disclosure presents a safe high speed roll-up door with spiral brackets. To enable a high speed operation, robust spiral brackets having efficient spacing are provided to guide the plurality of sectional slats. Durable and low noise signature rollers are used. A unique assembly configuration of the slats and the tracks guiding the rollers enable quick replacement of each individual roller without disassembling the door. A double-belt counter weight mechanism balances the door and incorporates safety sensors that prevent loosening the belts when the door is jammed. The belts are further adjustable using ratchets such that adjustment for the horizontal balance as well as weight position is made effortless. In all, the high speed roll-up door using sectional slats performs faster and quieter, withstands greater loads, and lasts longer than other existing roll-up doors with spiral brackets.
