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 protection system for an opening of a building is provided. The system includes a pair of side rails where the pair of side rails each has a pair of offset elongated protrusions contained within a cavity of the side rails. Further, at least one slat extending between the pair of side rails, the slat adapted to connect with the pair of offset protrusions within the side rails. In most embodiments, a plurality of slats are provided to roll up when not in use. A clip is connected to a distal end of the slat, the slat adapted to directly connect to the offset elongated protrusions contained within the cavity of the side rails.

The present invention relates to a gate with a gate panel, comprising several gate panel sections which are hingedly coupled to each other by way of hinges, where a hinge comprises two hinge panels of adjacent gate panel sections, at least one elongate drive means which is connected to at least one gate panel section, and at least one guide means which is suitable to guide the gate panel during its motion. In order to optimize the gate with regard to its installation space, in particular in the width and depth direction, and to ensure simple and inexpensive yet at the same time still reliable operation of the gate, it is proposed to arrange the elongated drive means at least in sections received in the gate panel section.

A roller shutter comprising a shutter moveable between a retracted position and an extended position is described. The shutter comprises one or more laths wherein the one or more laths comprise first and second surfaces mechanically connected by first and second sides and one or more internal supports. The one or more internal supports are configured to collapse preferentially with respect to the first and second sides. The presence of the one or more internal supports provides the laths with increased mechanical strength. However, by configuring the internal supports to collapse preferentially with respect to the first and second sides provides a means for absorbing and dissipating this force through the shutter. The roller shutter finds particular application as a horizontal shutter within heavy industry environments.

The present invention discloses a roller shutter for an automobile, comprising guide slots, a roller shutter, a lock catch assembly locked with the guide slots, a rolling and unrolling assembly, a plurality of groups of pre-positioning installation assemblies and locking assemblies. Compared with the prior art, the roller shutter for an automobile enables the two guide slots to keep parallel through the pre-positioning installation assemblies and the positioning and locking assemblies during the assembling of the roller shutter. Because the switching process of the roller shutter is smoother at the connection between the roller shutter and the guide slots, more labor is saved. A guide turntable enables the roller shutter to slide through frictional force with the slots of the roller shutter, rolling and unrolling become smooth. The lock catch assembly can lock and position the roller shutter at any time, flexibility is strong and freedom is high.

A roll-up door (10) with slats (60) rolled on a reel (12) with spiral guides (32) that maintain a tangent between the reel (12) and the closure plane at the point of entry/exit so as to maintain a perpendicular entry and exit with the side guides (36) and reduce friction, increase speed, reduce noise and help keep self-aligning end caps tracking correctly. It can also eliminate hinges between slats and permit each slat to be removed independently, without disassembling the other slats.

A roller-shutter door system comprises a pair of opposed substantially parallel guide rails and a door formed by longitudinally hinged door slats coupled to a retraction roller. The door can be opened and closed with rotation of the retraction roller, and longitudinal ends of the door slats ride within door guide channels in the guide rails. Exterior side seals may cover a gap between the door slats and the door guide channels, and wear shields may be interposed between coated exterior surfaces of the door slats and the side seals so that the side seals bear on the wear shields instead of the coated exterior surfaces. The guide rails may have equipment channels on interior sides thereof, and radius guides may be releasably received in open superior ends of the equipment channels. The radius guides have outwardly facing guide surfaces to guide the door slats toward the retraction roller.

A slat for a rolling shutter is provided that is formed as a single walled, continuous bent sheet. The slat includes a body having a hook-shaped engaging track at a first end, and a receiving track at the second end comprising a guard member and a hook-shaped lip member that form a pocket for receiving the engaging track of another slat. The guard member includes a portion of the sheet that is bent over on itself. The lip member extends from the guard member, and is spaced apart from the guard member to define an aperture that is sized and shaped to receive the engaging track of the other slat.
