A multifunction securing mechanism for a compartment closable by a door and includes a key cylinder, a latching assembly which may be a two-point latching assembly movable between a latching and an unlatching position, a rotatable member configured for a lazy-cam function connecting the key cylinder and latching assembly, at least one catch located on a surface adjacent the outside of the door, and a bar pivotally mounted to the outside of the door and movable between a first closed position and a second opened position. A first release mechanism is located on an interior side of the door for changing a positon of the latching assembly, and a second release mechanism is located on the interior side of the door for changing a position of the bar, both for allowing a user to open a latched and secured door from the inside.

A building structure 1a, 1b, and 1c incorporates an outer wall 6 provided on a lower side of a sloped ceiling 2 in a slope direction, an opening part 5 formed in the outer wall 6, a box-shaped groove part 15 formed at a lower end of the sloped ceiling 2 along the outer wall 6 and having a lower opening 14 opened downward, and an attachment part 17 provided inside the groove part 15 and to which an upper end part of a light shielding material 16 that shields light incident on the opening part 5 is attached, wherein the groove part 15 is a ceiling-embedded type embedded in the sloped ceiling 2, and a lower end of a side plate of the groove part 15 on a side opposite to the opening part 5 is lower than a height of a lower surface of a frame 23 on an upper side of the opening part 5.

The invention relates to a rolling door comprising a door leaf which can be moved between an open position, in which it at least partially releases a wall opening and forms a multi-layer winding above the wall opening, and a closed position, in which it at least partially closes the wall opening, as well as comprising joint assemblies arranged in the region of the lateral edges of the door leaf, at least sections of which are running in the direction of gravity in the closed position, and secured to the door leaf, for guiding the door leaf movement, each of which includes a plurality of joint elements articulately connected relative to joining shafts running perpendicular to the lateral edges and approximately parallel to the door leaf plane, wherein at least sections of the door leaf are made of a bendable material, such as a plastic film, which is stabilised by two, three or more stabilising devices running perpendicular to the lateral edges and in the door leaf plane, wherein the door leaf is only connected to the joint assemblies via the stabilising devices.

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.

A locking system for a rolling shutter that includes a plurality of rolling shutter slats, comprises a guide track with a U-shaped guide channel having a channel base, and first and second channel walls. A lock bar is coupled to the rolling shutter slats. In a locked position, the lock bar extends transverse to the channel base. The lock bar has a notch covered by a breakaway wall that is aligned with the channel base in the locked position. The lock bar may be slidably received in a sleeve that is positioned in the guide channel to increase resistance to torsional forces on the locking system. In an alternative embodiment, the locking system comprises a unitary extruded body, a lock bar, and a handle. A longitudinal channel is formed integrally in the body for receiving the lock bar and handle. The lock bar is slidable in the channel between an extended locked position and a retracted unlocked position. The handle is positioned in the channel to stop the retraction of the lock bar at the unlocked position.

A shutter roller door with a shutter roller drivable by a drive mechanism; a flexible door windable on the roller and movable between retracted and extended positions by the drive mechanism, the door having integrally formed interconnected slats, each having upper and lower edges, and arranged perpendicular to a direction of door travel; a guide rail assembly positioned at each side; and end members attachable to an end of a corresponding slat. Each slat has an upper hook portion and an upper curved channel, the upper hook portion configured to engage with a lower curved channel of the lower edge of an upper adjacent slat, and the lower edge having a lower hook portion and a lower curved channel configured to engage with the upper curved channel of the upper edge of a lower adjacent slat.

A vertically sliding roll-up door has a portal structure including vertical uprights provided with guide rails for guiding the sliding of blocks fixed along the lateral edges of the curtain, to allow the curtain to move vertically with respect to the portal structure. The curtain includes air-sealing gaskets which extend substantially over the entire length of the longitudinal edges of the curtain at the blocks, in order to block the passage of air between the guide rails and the blocks.
