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 time delay release mechanism has a brake actuator including an actuation member movable between engaged and released positions. The actuation member, when in the engaged position, operatively engages a fire barrier for preventing closure thereof. The actuation member, when in the released position, is operatively disengaged from the fire barrier such that the release mechanism does not prevent closure thereof. The brake actuator includes an actuation driver which, when receiving electrical power, moves the actuation member to the released position. A timer, when receiving electrical power or when power thereto is interrupted for a duration less than a predetermined time period, disengages from the actuation member allowing the actuation driver, when power thereto is initially interrupted, to move the actuation member to the engaged position. The timer engages the actuation member, when power to the timer is interrupted for a duration greater than the predetermined time period, to move the actuation member to the released position thereby overriding the actuation driver to allow closure of the fire barrier. The timer disengages from the actuation member when power to the timer is restored and the actuation driver retains the actuation member in the released position when power to the actuation driver is restored, thereby automatically resetting the brake actuator and timer.

摘要： The present invention is provided with a mechanism for controlling the opening and closing of a door comprising a speed reduction means for reducing a rotational speed. A high speed shaft is connected to the speed reduction means and is connectable to a means for rotating the input shaft, and a low speed output shaft is connected to the speed reduction means. A governor is mounted on the input shaft for limiting the rotational speed thereof, to also regulate the rotational speed of the output shaft. A brake is provided for preventing rotation of the output shaft, and a self-closing mechanism is operatively connected to the door. The self-closing mechanism is adapted for storing energy when the door is opened to an open position, and a connecting means operatively connects the output shaft to the self-closing mechanism. A releasing means is provided for releasing the brake to permit rotation of the output shaft under the urging of the self-closing mechanism whereby the self-closing mechanism releases the energy stored therein so as to close the door to a closed position when the brake is released by the releasing means.

摘要： A time delay release mechanism has a brake actuator including an actuation member movable between engaged and released positions. The actuation member, when in the engaged position, operatively engages a fire barrier for preventing closure thereof. The actuation member, when in the released position, is operatively disengaged from the fire barrier such that the release mechanism does not prevent closure thereof. A timer includes a magnet which is powered by voltage applied to a capacitor. The magnet is, in turn, connected to the actuator member. When power is interrupted, the capacitor disengages for a predetermined time period. At the conclusion of the time period the magnet releases the actuator which, in turn, releases the brake and causes the fire barrier to close.

摘要： A brake actuator for use in conjunction with a door barrier for preventing closure of the door barrier when the actuator comes in contact with an obstruction. The brake actuator includes a bumper mounted on a leading edge of the barrier and movable between an operative position and an inoperative position. A load carrying linkage is provided which is activated when the bumper is moved to the operative position. The linkage is connected to a brake which becomes engaged when the linkage is activated, thus preventing movement of the door barrier to a closed position when the bumper contacts the obstruction.

摘要： An assembly for covering an opening in a structure. The assembly has a roller to be mounted to a portion of the structure defining a portion of the structure opening and a member disposed on the roller assembly. The member is operable between a retracted position where it is wound onto the roller assembly and an extended position where it is unwound from the roller assembly. The member includes first and second portions with mutually opposing edges in a closed position. A fastener releasably attaches the first and second panel portions to each other. The first and second panel portions are separable in response to an egress force to form an egress through the member.
