摘要

The lock (1) has a pressure actuatable latch (4) and a cylinder lock actuatable bar (28). The bar is controlled in a pre closed position and withdrawn position during pusher actuation. The bar is pre locked by a lock beard of a cylinder lock (27) under interference in a door opening (37) of a latch end. A slide is protuberant into a rotational path of the lock beard by a spring load, for spacing the lock beard from an entry area of a door opening.
