The invention relates to a door comprising a door leaf (10) which can be moved between an open position and a closed position and a guide arrangement for guiding the movement of the door leaf along a predefined path between the open position in the closed position, wherein the guide arrangement has at least one guide web (100) which is arranged fixedly with respect to a wall opening, extends at least along a portion of the predetermined path, and has two outer boundary surfaces (102, 104) and at least two guide devices (32, 34) which are fastened to the door leaf (10), wherein a first outer boundary surface (102) of the guide web (100) forms a surface for a first guide device (32) and the second outer boundary surface (104) of the guide web (100) forms a second guide surface (104) for a second guide device (34). Magnetic devices (1000, 1010, 1100) can be arranged on the door leaf and on the guide bar for guiding in a contactless manner.

A roller shutter may include a rotatable drum; a shutter curtain including a series of three or more elongate slats pivotally interlocked in a longitudinal-edge-to-longitudinal-edge arrangement and arranged parallel to the rotatable drum, wherein a first and second longitudinal end portions of each elongate slat may be respectively aligned to form a first side border and a second side border, respectively, of the shutter curtain, wherein the first and second longitudinal end portions of each elongate slat may be respectively provided with at least one eyelet-structure which protrudes therefrom, whereby a first and second rows of eyelet-structures are formed along the first and second side borders; and at least a first cord and a second cord respectively strung loosely through all eyelet-structures of respective row of eyelet-structures, and each cord may be configured to confine all eyelet-structures of the respective row of eyelet-structures within a length of each cord.

An upright (1) comprising two sidewalls (2, 3) between which a profiled element (100) for a shading system can be inserted, and an end wall (6) between the two sidewalls (2, 3), is described. The upright is characterized in that one of the sidewalls is removable, and elastic means (200) are arranged between the removable sidewall (2) and the non-removable sidewall (3), in order to retain the removable sidewall (2) between the end wall (6) and the non-removable sidewall (3).

A system and method are provided for facilitating automated and manual segregation of internal areas within a structure, particularly in response to active shooter warnings, or other triggering events. Embodiments may provide automated systems and methods, products and product components 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.

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.

The present invention is a bottom assembly for a breakaway door. The bottom assembly comprises a first mounting plate fixed on one of the faces of the breakaway door proximate to its bottom and a security edge formed of a loop of flexible material suspended from the bottom of the breakaway door. The security edge has a second tab sandwiched between the first mounting plate and the breakaway door to mount the security edge to the breakaway door. The loop of flexible material has an interior void at least partially filled with an internal cushion. The bottom assembly further includes a first padded bar including a bumper and a first tab extending from the bumper wherein the first tab is sandwiched between the first mounting plate and the breakaway door to mount the first padded bar to said breakaway door.

The present disclosure relates to a barrier system for shielding humans from harmful exposure to fire, smoke, noxious fumes, or contaminated air. Some embodiments provide a deployable barrier system that has a barrier retract assist system configured to assist a user in manually moving the barrier from the deployed position toward the retracted position with at least a portion of the barrier being rolled onto the barrel portion for egress past the barrier. The retract assist system can be positioned inside of the barrel portion.

In one or more arrangements, a retractable screen system is provided. The system includes a roller tube having an exterior surface. A screen is connected to the roller tube and an upper edge of the screen. The system includes magnetic track assemblies having screen receivers configured to connect with and hold sides of the screen while permitting the screen to be raised and lowered. The magnetic track assemblies include tracks configured to attached to a structure and receive and hold the screen receivers in a channel between first and second side walls of the track. Magnetic attraction between the screen receivers and the tracks pulls screen receivers into the tracks and places tension on the screen. In one or more arrangements, the system includes retainers configured to connect with the first and second side walls of the track and prevent the screen receiver from coming out of the track.

A fenestration assembly includes a sash, a frame surrounding the sash, and at least one screen assembly mounted in at least one of: the top portion and the bottom portion. The frame includes a top portion, a bottom portion, and two jambs forming first slots extending lengthwise along at least a portion of the jamb. The first slots each include a screen edge retention feature. The screen assembly includes a roller assembly substantially hidden from view, a screen material attached to the roller assembly, and a plurality of raised features. Edges of the screen material extend into the first slots. The raised features are attached to each of the edges of the screen material. The raised features are configured to engage the screen edge retention features and retain each of the edges of the screen material at least partially within the first slot of each of the two jambs.

A shading device having a cloth that can be spread out, and is connected to a lead bar at its end pointing in the spreading-out direction and engages with a profiled guide rail on at least one side edge. The profiled guide rail is arranged in a channel-like chamber of a profiled holding rail and is resiliently supported on the profiled holding rail by means of a spring device, the spring device having a profiled spring rail. The profiled guide rail is inserted into a receiving space of the profiled spring rail that is delimited by spring clips and said profiled guide rail is floatingly mounted in the profiled spring rail, and the profiled spring rail is floatingly mounted in the channel-like chamber of the profiled holding rail and is supported on an internal wall of the chamber by means of at least one arm.
