A lining is provided that covers doors or windows to provide protection against all inclement weather conditions. The lining prevents sunlight or any other type light from entering inside a room. The lining that includes horizontal slotted blinds that are operated manually using a flat cord. The horizontal slotted blinds work using tongue and groove concept.

A covering for an architectural opening is provided. The covering may include a roller, a shade, and an assembly associated with the roller. The assembly may include a biasing element and a retention element. The biasing element may be operably associated with the roller to selectively rotate the roller. The biasing element may be preloaded. The retention element may be associated with the biasing element. The retention element may be operable to release the preload in the biasing element at an extended shade position.

A fabric fire rated door is described. The door utilizes a fire resistant fabric curtain with an end lock attachment. A tubular steel shaft is driven by an internal tube motor. The shaft is supported to minimize deflection. Single door shafts can also be joined together with a coupler shaft to create infinitely wide doors. The coupler shaft is spring loaded to act as a take up reel for a coupling curtain which will overlap each adjacent single door shaft. All curtains are attached to the same bottom bar. A hood covers the shaft, curtain, and the supports that run across the width of the door. The curtain travels over these horizontal supports as it drops down through the hood opening. The horizontal supports keep the curtain in position for proper seal during a fire/smoke event.

A rolling shutter driving device includes a motor, a locking assembly and a gearbox. The motor includes a stator and a rotor. The rotor includes a rotary shaft connected to the gearbox. The rotary shaft drives through the gearbox a rolling shutter to extend or retract. The locking assembly includes a brake pad slidingly fitted on the rotary shaft and a rotary member fixedly mounted to the rotary shaft. The brake pad is circumferentially fixed relative to the stator. The brake pad is slidable relative to the rotary shaft so as to be selectively engaged with the rotary member to lock the rotary shaft and hence hold the load in position, or disengaged from the rotary member to unlock the rotary shaft.

A base slat pry stopper, such as a base slat locking bracket, for locking a rolling shutter curtain covering an opening of a structure is disclosed. The base slat pry stopper may include a bracket base plate mounted to an opening bottom wall on an interior side of the shutter curtain, and a base slat engagement portion extending upward from the bracket base plate and above a top surface of the opening bottom wall. When the shutter curtain is unrolled to cover the opening, the base slat engagement portion engages the base slat to prevent the base slat from deflecting upward away from the opening bottom wall when a force applied from an exterior side of the shutter curtain causes the base slat to deflect toward the interior side of the structure and the shutter curtain. The base slat pry stopper may be permanently or removably installed.

An opening/closing direction restriction mechanism for a manual shutter device and an opening/closing direction restriction mechanism for a suspended sliding door device This opening/closing direction restriction mechanism is provided with: a flange fixedly mounted on a fixed shaft; a bracket which is loosely fitted to the fixed shaft and can be integrally rotated with a winding member; and a two-way clutch which can be switched between a reverse rotation inhibited state in which the revolution of a planetary external gear along a winding direction of the winding member is allowed and the revolution of the planetary external gear along an unwinding direction is inhibited, and a forward rotation inhibited state in which the revolution of the planetary external gear along the winding direction of the winding member is inhibited and the revolution of the planetary external gear along the unwinding direction is allowed.

A locking mechanism for use with a door structure having a corrugated surface includes a main body having a corrugated surface. The locking mechanism is configured to be adjustable between an unlocked position where the corrugated surface of the main body is not nested relative to the corrugated surface of the door structure and a locked position where the corrugated surface of the main body is nested relative to the corrugated surface of the door structure. The corrugated surface of the main body includes a plurality of engagement surfaces. Each of the engagement surfaces is configured to resist movement and/or deformation of the door structure with respect to a direction of movement of the door structure associated with the door structure being moved from a closed position towards an open position.

A door, in particular a high-speed industrial door, with an intelligent door leaf is disclosed. The door has a door leaf which is guided by lateral guides and covers a door opening, and which has a first and a second side, a driving means for moving the door leaf between an open and a closed position, a door control means for controlling the driving means, as well as an electrically self-sufficient door leaf means arranged in the door leaf. The door control means also has a first communication unit. In addition, the door leaf device comprises at least one sensor unit for detecting at least a physical quantity, an energy converter which converts non-electrical energy into electrical energy, a second communication unit and at least one actuator unit. The first and second communication units communicate wirelessly with each other.

A shower-screen retraction system (10) for providing a temporary, self-retracting and self-cleaning barrier for a bath or a shower, comprises a screen-mounting support member (12) having a biasing means (26) and a housing (19). A screen (16) has a first screen end (62a), associated with the screen-mounting support member (12), and a second screen and (62b) opposite to the first screen end (62a). The housing (19) is an irregular polygon in cross-section into accomodate a screen-wiper (46) whilst optimising an internal volume to avoid impingement of the screen (16) once furled.

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.
