A slatted door includes a plurality of interengaged slats, and end members arranged at ends of respective slats. The end members and the slats are configured and arranged so that, when the slats are engaged with one another and with respective end members, at least one lateral reinforcement impact distribution structure is formed. The impact distribution structure is configured to absorb, distribute and/or redirect impact force in a direction along the length of the slats.

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 panel assembly including a panel that can be positioned in an opening, the panel including a plurality of locking members spaced apart along at least part of a length of and proximate to opposing longitudinal edges of the panel and a guide extending along either side of the opening, each guide including at least one locking flange extending along at least part of a length of the guide, wherein in use the panel is received in the guides so that the locking members selectively engage the flanges to limit lateral movement of the panel edges.

A shutter for protecting an opening. The shutter comprising a plurality of horizontal curtain slats for covering the opening, wherein horizontal refers to a direction when viewing slats from a front surface, and wherein the curtain slats hang freely from a upper region of the opening; an upper transition slat movably affixed to a lower end of a first curtain slat; a lower transition slat movably affixed to an upper end of a second curtain slat; and a horizontal reinforcing member comprising at least an upper and a lower reinforcing slat, wherein the upper reinforcing slat is rotatably affixed to a lower end of the first transition slat and the lower reinforcing slat is rotatably affixed to an upper end of the second transition slat, and wherein the upper and lower reinforcing slats are rotatably joined.

An architectural covering with an operable vane having a fabric backing is provided. The vane may include a vane fabric and a backing material connected to the vane fabric by a layer of adhesive. The backing material may increase a machine-direction stiffness of the vane while slightly affecting a cross-direction stiffness of the vane. As such, the vane may have increased stiffness in its machine direction while simultaneously remaining flexible in its cross direction.

A rolling door slat designed to deflect, redirect or absorb severe force is disclosed. The present invention utilizes a double slat design with layered joints, and an open volume enclosing a reinforced core. The reinforced core of the present invention consists of either a solid block of dense, protective material, or layers of material. The layers of material serve to both deflect and absorb impact and blast force, resist vertical force, as well as provide more traditional rolling door functions such as fire resistance or sound and heat insulation.

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.

The construction of rapid opening thermally insulated roller doors is challenging in that there are both structural and operational challenges. The door blades need to have structural strength, and also need to have dimensional stability. Disclosed is a thermally insulated roller door blade in which at least the material forming the outer surface is able to resist the tensile loads during retraction, and the blade is provided with flexible spacer strips that help the primary insulating material of the door blade to maintain dimensional stability, primarily by helping to resist crushing. This allows softer materials to be used for thermal insulation than previously used, helping to reduce weight and to improve thermal efficiency, while at the same time allowing smooth and repeatable operation even when exposed to freezing temperatures for long periods.
