摘要 |
An apparatus is disclosed for releasably locking a fireproof door in an open position. A latch mechanism includes a hook connected to the door. The hook is releasably engaged with an actuator plate swingable between a latching position and a release position. Its motion is restricted by resilient means having bias adjustment means. A toggle mechanism keeps the actuator plate in its latching position until the toggle mechanism is struck by a remote-controlled solenoid plunger to release the door and let it close. If the solenoid malfunctions, the door can be closed manually with a force dependent on the setting of the bias adjustment means. |
