<p>A door locking mechanism 8 is described having an espagnolette mechanism interconnecting longitudinally movable bolts 12 at the periphery of a door 4. The bolts 12 have individual deadlocking mechanisms that serve to prevent their own movement and via the espagnolette mechanism the movement of all the other parts of the door locking mechanism 8. The bolts 12 are deadlocked by the action of a bush 26 fitted within a slot 24 in the bolts 12 and applying a transverse force thereto. The deadlocking of the bolts 12 serves to compress the door 4 shut. <IMAGE></p> |
