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 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 master/slave shaft arrangement includes: a motor having an output shaft; a master drive barrel, the first end of which being rotationally driven by the output shaft of the motor, the master drive barrel having, at a second end thereof, a master drive sprocket; a synchronizing shaft that is rotationally driven at its second end by a first coupling assembly, the rotational driving of the synchronizing shaft being synchronous with the rotational driving of the master drive barrel by the motor; and a slave barrel, the slave barrel being rotationally driven at its first end by a second coupling assembly that rotationally couples the synchronizing shaft with the slave barrel to rotationally drive the slave barrel, the rotational driving of the slave barrel being synchronous with the rotational driving of the synchronizing shaft and the rotational driving of the master drive barrel by the motor.
