AbstractA locking device for doors, intended for connection between the dead-bolt of the door and the drive means of the lock including a hinged arm which is connected to the dead-bolt or its extension, a wheel or pin being arranged at the other end of the hinged arm and designed to tumble into a recess formed in a pivotable cam-disc, or to be disengaged from this recess by means of a link mechanism, whereupon in the latter position, the cam-disc is arranged to block the dead-bolt in the first position and upon tumbling into the recess to release it, the dead-bolt has an inclined surface designed so that upon pressure against the door, the bevelled surface assists in opening of the door.
