Abstract (en)
A lock mechanism particularly suitable for an emergency door in a railway platform edge screen. The door is normally locked shut but on the side facing the track has a panic handle for emergency use. On the platform side a "secret" means is provided for unlocking the door which releases a movable latch keeper which normally locks the door by positively engaging a latch bolt. The keeper is prevented from moving by a locking means held in position by the armature of an energised solenoid. The "secret" unlocking means temporarily de-energises the solenoid which withdraws the locking means permitting movement of the keeper if the door is opened. After a predetermined delay period the solenoid is re-energised and the door is automatically re-locked.
