Abstract: 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.

Abstract: A releasable door hold-open mechanism, for use with a door closer, is disclosed. The mechanism employs a latch assembly, mounted in a track which defines a predetermined path for a slider shoe associated with a door closer arm. The latch assembly employs a pair of reciprocable rollers, associated with a solenoid activated clevis. When the solenoid is actuated, the clevis maintains the rollers in a latching position, in which they can capture and hold a wedge associated with the slider shoe. Deactivation of the solenoid permits release of the wedge, and the force of the solenoid can also be overcome manually to release the wedge. The latch assembly is selectively positionable in a broad range of positions within the track, to determine the angular position of the door at which holding occurs.

Abstract: In an apparatus for closing a fireproof door in case of emergency, the fireproof door and a release, which is secured to a door frame, are interconnected by a link mechanism comprising first, second and supplemental link arms. One end of the first link arms is pivoted to a driving shaft of a door closer secured to the fireproof door. The other end of the first link arm is pivoted to one end of the second link arm, the other end of which is pivoted to the release. The supplemental link arm is connected between the central point of the second link arm and a slider which is slidably mounted inside the release and latched by a latch mechanism when the fireproof door is open.When the slider is released from the latch mechanism by electrizing a solenoid which operates the latch mechanism, the slider is slid inside the release by the closing force of the door closer transmitted via the link mechanism, thereby closing the fireproof door.

Abstract: A revolving door system has a central axis defining center shaft and three wing hangers rigidly joined and extending in equidistant spaced apart relationship about the center shaft's upper portion. Pivots couple three planar upright wings in closely spaced apart relationship to the center shaft. A magnetic latch on each wing hanger is spaced apart from the central axis more remote than the pivot, releasably maintaining the wings in ganged alignment with the hangers.A pair of facing substantially semicircular walls, spaced apart to define regions of ingress and egress, partially surrounds the wings and shaft on opposite sides. Each wall has two adjacent movable side panels hinged on opposite sides of a center panel, movable from a nominally enclosing position to an open panic position.Disposed remote from the adjacent side panel, a magnetic latch releasably maintains the side panels in circular alignment with the enclosure. A smoke detector is coupled to the electromagnetic latch means to cause a disengagement of the latch means in response to an indication.In a panic situation, release of the latch allows the wings to be released from the hangers and pivoted freely while the side panels are allowed to pivot about the hinges to enhance the egress frontage to thereby potentially increase the flow of people exiting from the building structure.

Abstract: This disclosure relates to an electrically actuated door holder and release for the multi-point holding of a pivoted door at selected door opening angles, and for the release of a held door either electrically or in response to manual override. The door holder and release includes a rotatable spindle adapted to be connected to a pivoted door which is either push or pull-side mounted. The holder and release comprises a spindle gear assembly having a pair of male spline gears with each gear having a circular ring of splineways forming a series of male projecting keys. A pair of cams, each having cam lobes defining detent segments with each cam having a circular hole internally grooved to mate with the projecting keys of spline gear, is mounted on the shaft. A pair of springs yieldingly hold the cams into mating positions with associated spline gears to rotate therewith. A double lever having a common pivot or fulcrum carries a roller which follows the cams. The lever may be electromagnetically actuated and released to effect a door hold and release, or alternatively, the lever may be manually overridden. The selected hold-open angles may be set and altered, without removal of the holder and release or the associated door closer from their fixed positions on a header frame and door, respectively. This function is attained by the arrangement of the cams on the spline gears in association with depressible springs which enable the cams to be manually adjusted without removal of any component except the housing cover.

Abstract: A surface-mounted door holder-closer responsive to the particulate products of combustion passing through multiple passageways formed in a holder-closer housing cover, a holdercloser assembly frame, and a dark chamber which is an integral part of a photocell particle detector module. The particle detector module is insertable into the holder-closer frame with the frame and dark chamber walls not only defining the passageways, but also isolating the chamber from spurious light entering the chamber which would render a false alarm or false emergency door release. The frame also houses the principal components of the holder-closer, namely, a closer spring, a dashpot, a latching lever assembly, and an electromagnet responsive to modulated output current flow from the dark chamber to effect alarm or emergency release of the latching lever to close an otherwise open door. The integrated detector-holdercloser is advantageously and simply mounted on the lintel or header of a door frame.
