摘要

The casing (1) has a trap ejector (7) and a latch ejector (9) that are pivotably coupled to a lock mechanism that is movable between a retracted position and an extended position. A spring unit (21) is assigned to the lock mechanism for providing swinging movement. The pivoting of the lock mechanism is ended before the extended position is reached, and further swiveling of the lock mechanism into the extended position after pivoting of the lock mechanism is exclusively carried out by the spring unit.
