摘要： A locking device incorporates a lock case, an escutcheon housing and a door handle. The lock case houses a spring bolt mechanism operable by the door handle and a dead bolt mechanism operable by a locking mechanism. The spring bolt and the dead bolt are separately latchable. The escutcheon housing contains a substantial part and preferably the whole of a lock cylinder mechanism for latching the spring bolt. The dead bolt mechanism is adapted to be actuated, at any rate from one side, by a key via lock cylinder mechanism or a tumbler lever mechanism. From the other side the dead bolt can be latched or released via the said tumbler lever mechanism, a separate lock cylinder mechanism or a handle. Said handle may also cooperate with the spring bolt via a separate mechanism contained in a second escutcheon housing. When the dead bolt is actuated by a tumbler lever mechanism a cover plate in the escutcheon housing preferably cooperates with the spring bolt mechanism so that it covers the key hole for the tumbler lever mechanism when the spring bolt is being latched.
