A tambour door has an elongated first slat, at least one elongated second slat extending parallel to and adjacent the first slot and a deformable connecting strip extending along the first and second slats. Interengageable anchor formations on the strip and on the slits coupling same together while permitting the slats to move limitedly transversely of themselves relative to one another.

An opening and closing body includes a plurality of rod-shaped members, and a plurality of coupling members configured to couple the plurality of rod-shaped members. Each of the coupling members includes a pair of fitting parts that are spaced apart in a guide direction and configured to be fitted to a coupling target pair of rod-shaped members that are adjacent to each other in the guide direction. Each of the fitting parts includes a cover part having flexibility and configured to cover a range of an outer circumferential surface of the fitted rod-shaped member, the range being smaller than a circumference of the outer circumferential surface and larger than half the circumference as viewed in a first direction.

Various disclosed embodiments include illustrative door assemblies, vehicles, and methods of assembling door assemblies. In an illustrative embodiment, a door assembly has a right horizontal track, a left horizontal track, a counterbalance assembly having a right end and a left end, a right connector plate, and a left connector plate. The right connector plate is configured to be connected to the right horizontal track and to the right end of the counterbalance assembly. The left connector plate is configured to be connected to the left horizontal track and to the left end of the counterbalance assembly.

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 roll-up door with fall protection preferably includes a door web, a pair of guide tracks, a pair of lower track brackets, a plurality of upper track brackets and a door web roller. The door web includes a plurality of screen web panels and wind bars. Opposing ends of the door web are retained in the pair of guide tracks. A first wind bar is arraigned to be 42 inches off a floor to meet OSHA fall protection standards. The door web includes at least two upper wind bars above the first wind bar and at least one lower wind bar below the first wind bar. The pair of guide tracks are secured to a wall with the pair of lower track brackets and the plurality of upper track brackets. A top of the pair of lower track brackets are located at least 42 inches above the floor.

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.

The present disclosure provides a water-blocking device including a water-blocking plate installed on a floor of a passage, rails installed on both sidewalls of the floor, and a driving part configured to lift and lower the water-blocking plate, wherein, when the driving part is operated, the water-blocking plate is lifted and lowered along the rails.

The invention relates to a vertically movable gate with a gate panel comprising several gate panel segments, where two adjacent gate panel segments are each hingedly connected to one another by way of at least one hinge, and with a motorized drive which transmits a force for lifting and lowering the gate panel via at least one drive means to the gate panel, and a connection means for connecting the drive means to the gate panel. Gates of the type mentioned at the outset are improved according to the invention such that, though such a gate can be moved easily between an open and a closed position largely independent of the forces arising, it nevertheless provides a compact and simultaneously stable and fail-safe design in that several gate panel segments are each individually connected to the drive means.

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.

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.
