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.
摘要翻译：在用于关闭防火门的装置中，保持装置包括闩锁机构和滑块。闩锁机构包括可摆动地支撑在壳体中的致动器构件，该壳体设置有管状部分，其中止动件被弹簧插入并向下偏置，弹簧的偏置力可通过螺纹被调节到管状部分中。滑块在其前端设置有倾斜表面，并且在其中容纳止动件的通孔。滑动件滑动到致动器构件和壳体之间形成的间隔中，并通过滑块的倾斜表面向上引导止动件，并且当滑块落入滑块的通孔时，滑块被止动器锁定。滑块通过使致动器构件摆动或克服弹簧的偏置力向上推动止动件而从闩锁机构释放。

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.
摘要翻译：在紧急情况下用于关闭防火门的装置中，防火门和固定到门框的释放件通过包括第一，第二和辅助连杆臂的连杆机构相互连接。第一连杆臂的一端枢转到固定在防火门上的门把手的驱动轴上。第一连杆臂的另一端枢转到第二连杆臂的一端，另一端枢转到释放位置。辅助连杆臂连接在第二连杆臂的中心点和滑动件之间，该滑块可滑动地安装在释放件中并且当防火门打开时由闩锁机构锁定。当滑块通过电动操作闩锁机构的螺线管从闩锁机构释放时，滑块通过经由连杆机构传递的门关闭器的关闭力在释放部内滑动，从而关闭防火门。
