The present disclosure discloses a power-assisted pulling device for a roller shutter cover. The device includes a canister. The top of the canister is fixedly connected with guide rails, and inner cavities of the guide rails are movably connected with a roller shutter. The present disclosure has the advantages that roller shutter leaves are rolled up smoothly and the roller shutter can be completely collected, and solves the following problem.

A battery-powered, motorized window treatment may include a fascia that pivots between a conceal position wherein the fascia covers a window treatment assembly and a battery compartment, and an expose position wherein the fascia does not cover the battery compartment. The fascia may be a two part fascia that includes an arm and a cover that pivots relative to the arm when the battery compartment is operated between respective opened and closed positions. The arm may be attached to the battery compartment such that the arm remains in a fixed orientation relative to the battery compartment. The arm and the cover may define complementary pivotally interlocking connectors that define a pivot axis about which the cover may pivot relative to the arm. The fascia may be configured to generate a perceptible indication when the fascia pivots into the conceal position, and/or when the fascia pivots into the expose position.

The present disclosure provides a non-powered open/close fireproof shutter including a shutter, a shutter track which is disposed in a horizontal direction and guides both end portions of the shutter in a width direction, a coil box in which a winding shaft for winding the shutter is installed to store the shutter in a coil form, a winding motor which rotates the winding shaft, and a weight which is connected to the shutter and deploys the shutter stored in the coil box along the shutter track. The non-powered open/close fireproof shutter according to the present disclosure can significantly reduce initial facility investment and maintenance costs, prevents malfunction of the fireproof shutter, which may occur when power is lost due to a loss of an emergency power source, in advance, and can secure reliability of a fire blocking function.

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.

A header assembly and method for installing built-in retractable screens. A header assembly is installed after the structure's framing is completed but before the wall finishes are applied. The header assembly includes opposing end boxes and a header board. The side tracks from the screen unit are installed so that the upper ends open into the bottom of the end boxes. This defines a cavity customized to the selected screen unit. With the header assembly and side tracks in place, the wall surfaces can be applied around them. After the wall surfaces are completed, the screen unit is placed inside the header assembly through an access opening, which is then covered with a cover panel. Thus, the present invention eliminates the need to apply wall finishes around an undefined space, which requires multiple measurements and often results in expensive mistakes in the finished cavity dimensions.

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.

The present invention relates to roll-up wall and acoustic barrier system (608) which may include an elongated member (300, 670). The elongated member may include a front wall (302), a rear wall (303) spaced from the front wall, a bottom wall (304), a first top wall (326a) adjacent the front wall, a second top wall (326b) adjacent the rear wall, and a channel (86) between the first top wall and the second top wall. The channel may comprise a first side wall (86a), a second side wall (86b), a first ledge (86c), and a second ledge (86d). The first and second ledges may define a slot (88) between the first side wall and the second side wall. The elongated member may further comprise a conduit (466) disposed between the front wall (302) and the rear wall (303) that is connected to the channel via the slot.

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 movable bulkhead assembly configured to partition an interior of a motor vehicle is provided. The assembly comprises a segmented shutter and a track assembly configured to guide the movement of the segmented shutter. The track assembly comprises a first vertically extending track portion, the segmented shutter being movable along the first vertically extending track portion to deploy or retract the bulkhead.

A door assembly with a flexible door movable between a retracted position and an extended position and having interconnected elongate slats having two lateral ends to form respective lateral edges of the flexible door. An automatically-locking bottom bar connects to a bottom-most slat of the flexible door. The bottom bar has anchors extending from the lateral ends thereof, the anchors extending beyond the respective lateral edges of the flexible door. A pair of guide channels receives the respective lateral edges of the flexible door, each guide channel having a reduced width portion in a bottom portion thereof to receive a respective one of the anchors when the bottom bar passes into the bottom portion of the pair of guide channels, the reduced width portion being laterally spaced from a lateral end of each said guide channel so that the respective anchor is locked in each said guide channel.
