Locking device for a door wing movable in a case

摘要

The bolt (12), on the inside (10) of the door or door leaf and moved by means of the manually operated lock (25) is tensioned by a helical spring arrangement (5) which holds the bolt in its open position. The bolt is held in its closed position when the door or door-leaf (1) is closed, by means of a holder arrangement (14) comprising a blocking device (31). The holder arrangement has a thrust bearing (14) for the bolt, in the form of a first end (11) of a closure bar (4) whose other end is joined to the lock. One end (19) of the helical compression spring is supported on a guide (6) for the door-leaf; the other end (20) comprises a stop (21) on the closure-bar for forcing the bar into the open position towards (48) the lock.
