Abstract: A device for restricting the opening motion of a door comprises a housing (4) for securing to the door and having an opening (6) facing the floor over which the door moves when it is opened and closed. A pivotally movable cam member (5)(5') is mounted within the housing so that it can pivot between an operating position in which it extends through the opening to engage with the floor and prevent opening movement of the door and a retracted position in which it is spaced from the floor. Levers (18,21) (18',21') are provided for moving the cam member between its operating and retracted positions.

Abstract: A locking mechanism comprises a plurality of spring loaded tines disposed around an armature. The armature has a disc mounted thereon the radially outer surface of which is profiled. The armature is coupled to a solenoid which is selectively energized to move the armature. In a locked position the profiled surface of the disc urges the spring loaded tines outwardly into engagement with a locking cup. In an unlocked position the armature moves the disc into a position so that the profiled surface allows the tines to spring inwardly so they can be withdrawn from the locking cup. A spring loaded sleeve is provided which holds the tines and the armature in the unlocked position so that the locking mechanism can re-engage in the event of a power failure to the solenoid. A pin is provided so that the solenoid can be overridden manually.
