Locking piece for door leaf movable in case, with lock, bolt and spring

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.
