摘要:
A high speed roll door is movable between an open and a closed position at an opening of a building. The door includes a flexible curtain and a pair of side columns. Each side column provides an inner track to guide the curtain in vertical movement and restrain the curtain from lateral movement during deployment and retraction. The curtain further includes multiple cross bars supporting the flexible curtain from one of the pair of side columns to the other. Each of the cross bars further includes a first longitudinal bar sandwiching part of the curtain; and a second longitudinal bar pivotally connected to the first longitudinal bar. The hinge has an axis of rotation parallel to the first and the second longitudinal bars. At least a wheel is rotatably affixed to each end of the second longitudinal bar to engage the inner track of each of the side columns.

Door with a door leaf which, starting from a closed position, can be wound up to form a multi-layer winding in the course of an opening movement and has a plurality of slats which customarily extend horizontally with their longitudinal axes approximately perpendicular to the direction of the opening movement, and with a guide arrangement for guiding the opening movement comprising preferably helically shaped guide rails in the region of the lateral edges of the slats in planes extending approximately perpendicularly to the longitudinal axes of said slats, and guide elements mounted on lateral edges of the slat which leads during the opening movement can be introduced into the radially outermost windings of said guide rails, wherein the guide elements (42) are fastened to the lateral edges of the leading slat (40) via pivot levers (50) on the leading slat and are mounted on the slat so as to be pivotable with respect to pivot axes extending parallel to the longitudinal axis of the slat.

A rolling door or shutter (1) has a series of preferably planar panels (3, 3A) which are joined by pairs (6) of pivotally connected hinge members (7, 8). The shutter slides up and down with its side edges guided in tracks (2). When the shutter is closed, e.g. against a bottom sill, the hinge members of each pair (6) pivot about one another to jam between opposing walls (30, 31) of the guide tracks. The pivotal range of each hinge pair may be limited to prevent the hinge pair from straightening when the shutter is suspended. This ensures the hinge pairs always fold in the same way when the shutter is closed. The panels may be rolled steel, extruded aluminium, moulded (optionally transparent) polycarbonate plastic, or tempered glass sheets fitted with edge cappings.

A rolling shutter and a slat for use in a rolling shutter are provided. The slat comprises an engaging track located at a first edge and a receptacle track located at a second edge. Illustratively, the engaging track has a hook-shaped profile and is disposed at an acute angle relative to an adjacent part of the body portion, is disposed at an angle of less than 180° relative to a vertical axis of the slat, or has a hook-shaped profile that curves for more than 180°, and the receptacle track comprises a lip and a guard defining a space adapted to receive therein an engaging track of an adjacent slat.

A barricade apparatus for providing a barrier across the gap between door sections of a sectional door. The barricade is fabricated from a strip of resilient sheet material formed into a generally L-shaped configuration along its length. The horizontal foot portion of the L-shaped configuration is secured to the upper edge of a lower door section to thereby support the vertical leg portion across the gap that opens and closes as the adjacent door sections are moved across the curved portion of the support track of the sectional door.

An improved joint construction (10) for a roll-up door includes specially-configured upper and lower panel sections (12, 11), a specially-configured hinge member (13) adapted to be longitudinally inserted into operative engagement wiht lower panel section, and a seal member (14) protectively concealed within a recess (73) in the upper panel section. The hinge member is coated with a low friction material to facilitate its longitudinal insertion into operative engagement with the lower panel section, and to facilitate relative movement of the adjacent panel sections. The lower panel section has an upwardly-extending lug (42) which is arranged to enter the recess in the upper panel section and compress the seal member when the adjacent panels are in vertically-aligned relation to one another.
摘要:
An insulated panel for rolling closures. The panel has a front wall and a back wall joined by side walls, and is filled with insulation. The side walls have thermal breaks formed by spacers. The size of the spacers can vary to vary the thickness of the panel. The panel has a hinge socket formed in the back wall adjacent one side wall. An extension of the back wall, projecting past the other side wall, carries a hinge pintle.

To a grille of standard construction there are added plastic slats to provide a solid barrier creating maximum security and visibility, wherein opposite ends of the added slats are merely crimpled to prevent their removal from the construction. The crimping, however, is not vulnerable to tampering due to their out-of-reach location in the tracking structure of the grille.
摘要:
A closing element for roller shutters comprising a central portion designed to be arranged, in use, according to a closing plane of an access opening of a room to at least partly close the access opening, and at least two connecting portions located on opposite edges of the central portion, each of which designed for connection of the closing element with at least one other closing element. Each connecting portion extends about a respective axis and defines a cavity for housing a connecting bar. The connecting portion has an open profile so that the cavity is accessible transversely to the axis.
