摘要： A locking device for locking a leaf of a leaf installation has first and second locking elements with respective first and latching elements. The second latching element is located at an end facing the first latching element and capable of a latching operative engagement with the first latching element. The second locking element is stationarily disposed relative to the leaf installation. The first locking element is disposed with regard to the leaf to move correspondingly to a movement of the leaf, so that the first locking element is moved translationally into a locking position towards the second locking element and away from the second locking element into an unlocking position. One of the locking elements has an activating element operable to allow for the latching operative engagement between the latching elements in a blocking position and to prevent the latching operative engagement in a release position.

摘要： The present invention relates to a hold-open apparatus for controlling the position of a door, preferably a screen door or storm door. The apparatus is used in conjunction with a piston assembly and can maintain a door in a predetermined open position, such as about 45° to about 100° in relation to a closed position. In a preferred embodiment, the apparatus can automatically lock and/or unlock when the door reaches predetermined positions. The apparatus advantageously can be retrofitted to existing door assemblies.

摘要： 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.

摘要： A door hold-open device is adapted to work with a conventional single-arm door closer. The device comprises a shoe moving along a track and connected to the closer operating arm. A detent in the form of a wheel is provided in the track which can be lowered through linkages by a solenoid to engage the shoe. Spring pressure on the detent can be adjusted in the field. The detent holds the shoe at one end of the track so that the door is held open. But the door can be forcibly closed causing the shoe to raise the detent, or the solenoid can be deactivated to raise the detent.

摘要： In an apparatus for closing a fireproof door, a holding device comprises a latch mechanism and a slider. The latch mechanism comprises an actuator member swingably supported in a housing which is provided with a tubular portion wherein a stopper is inserted and downwardly biased by a spring, the biasing force of the spring being adjustable by a screw which is threaded into the tubular portion. The slider is provided with an inclined surface at the front end thereof and a through-hole to receive the stopper therein. The slider is slid into the spacing formed between the actuator member and the housing with upwardly guiding the stopper by the inclined surface of the slider and the slider is locked by the stopper when it falls into the through-hole of the slider. The slider is released from the latch mechanism by swinging the actuator member or upwardly pushing the stopper against the biasing force of the spring.

摘要： 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.

摘要： A door control comprising a heat-actuated door latch and a combination door-closing-arm holder and release. An optional smoke detector is located within a holder-release housing. During normal conditions, the door-closing arm is set at a hold-open angle free of the door to permit an easy door swing. In response to an emergency or smoke condition, the closing arm is released to pick up and close the door. In the event of excessive heat, the door is latched in response to the separation of fusible link segments. Heat from the side of the door opposite the latch housing is conducted through the door by a heat conducting rod.

摘要： 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.

摘要： A normally pressure-free, failsafe, emergency door closer for use in hospitals, nursing homes or other locations where handicapped persons are housed, comprising an actuating mechanism triggered by a sensing device such as a smoke detector, a spring-loaded arm with a bumper on one end to engage the door and the other end of the arm rotatably attached to the wall adjacent to and above the door and free to rotate in a horizontal plane. The spring-loaded arm is retained in an open position by a vertical pin engaging the horizontal closer arm. The pin is mechanically linked to the armature of an electromagnet opposed by a coil spring. On signal from the sensing device the electromagnet releases the armature and the coil spring urges the pin upwards releasing the closer arm, the end of which engages the door and closes it.
