摘要： A drive arrangement for a roller curtain covering an opening defined by a frame includes a drum mounted horizontally across one side of the opening, a pair of hollow drive shafts fixed against rotation in opposite ends of the drum, and a pair of coaxial tension shaft portions fixed to the frame and received through respective hollow drive shafts. At least one coil spring is associated with each tension shaft portion, each spring having a first end fixed to a tension shaft portion and a second end fixed to the drum. A pair of drive motors are operatively connected to respective hollow drive shafts for synchronously rotating the drive shafts in order to coil a roller curtain on the drum.

摘要： A two-sided fire door system includes a horizontal head track having a first end and a second end; a first door including a plurality of interconnected panels suspended vertically from the head track by trolleys arranged for horizontal movement between the first end and a point remote from the first end; a second door including a plurality of interconnected panels suspended vertically from the head track by trolleys arranged for horizontal movement between the second end and a point remote from the second end; and an endless chain in an elongate loop having a first end looped around a drive sprocket and parallel first and second runs fixed to respective first and second lead trolleys. A drive motor rotates the drive sprocket in opposite rotational directions to open and close the doors, the motor being blocked against rotation when the motor is not operating. A suspended weight closes the doors automatically by means of a cable attached to one of the lead trolleys when the blocking is released.

摘要： A multi-layer rolling fire curtain assembly includes: a rotatable curtain roller positionable about a structure opening; a multi-layer fire curtain wrappable about the curtain roller and to be deployable from the curtain roller between an extended position and an open position, the fire curtain having a first end fixed to the curtain roller, and a free end, the free end being movable between a retracted position and an extended position. The fire curtain has: a fire resistant inner curtain layer arranged closer to the curtain roller, and a fire resistant outer curtain layer arranged opposite the inner layer. The inner and outer layers are affixed to one another by horizontally oriented connection seams, to connect the inner and outer layers to each other, the connection seams being configured so that the outer and inner layers are spaced apart by a plurality of baggy areas formed between adjacent connection seams.

摘要： A coupling for a door/curtain includes a plurality of coupling mechanisms affixed to ends of slats of the door/curtain. Each coupling mechanism includes a roller mounting bracket having a first roller arranged at an upper portion of the roller mounting bracket, and an extending portion, oriented at approximately 90 degrees with respect to the upper portion of the roller mounting bracket; and at least one second roller. Each second roller is rotatable around an axis perpendicular to the axis of rotation of the first roller. The first roller and the at least one second roller are arranged so as to cooperate with an outer track, inner track, roller support guide and first and second roller guides of a guide rail assembly to ensure that the door/curtain moves rollingly within the guide rail assembly even when the door/curtain is subjected to a deflecting force.

摘要： A rolling door assembly for selectively covering an opening in a building includes a shutter roller rotatable about a substantially horizontal axis and a flexible panel windable on and off the roller for movement into retracted and extended conditions, respectively. The flexible panel defines an upper portion having a first width and a lower portion having a second width less than the first width. At least one pass door frame is hingedly securable proximate a lateral side of the opening for movement between a first position, in which the pass door frame extends in a substantially transverse direction relative to the opening and a second position, in which the pass door frame is substantially aligned with the at least one sidewall. A pass door is movably mounted within the passage defined by the pass door frame to selectively provide ingress and egress therethrough and a closure system is provided for causing the pass door frame to move from the second position to the first position prior to extension of the flexible panel.
