    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 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, the pass door frame defining a passage therethrough and a substantially vertical channel for guiding an edge region of the flexible panel lower portion as it is extended. 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.

    摘要: A resettable fail-safe fire door release mechanism which allows normal powered operation of a fire door is disclosed. A solenoid having a first open state in the absence of an applied electric current and a second closed state in the presence of an applied electric current is incorporated into the motor-operator unit of an overhead door. Brake actuator utilizes the spring force of a normally disengaged brake to keep the brake actuator in a first position. The plunger of the solenoid acts through the brake actuator in opposition to the spring so that energizing the solenoid overcomes the force of the spring, moving the brake actuator, and engaging the brake; deenergizing the solenoid causes the spring to again disengage the brake. A normally closed switch having a mechanical actuator is wired in series with the solenoid. The melting of a fusible link releases a spring loaded plunger which depresses the actuator opening the switch. A cable having one end connected to the actuator of the switch and the other end external to the case of the motor-operator allows manual opening of the switch and hence closing of the door.

    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: 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.
