ABSTRACT:
A doorleaf lock, comprising a lock mechanism for controlling a locking bolt (12) and a catch bolt (15), which is controlled by means of a door handle. The catch bolt, in a neutral position defined by a spring means (21), extends with a non-circular bolt head (17) through a non-circular opening (16) in the lock front wall (11). The catch bolt is displaceable into the lock, against the action of the spring means (21), during manipulation of the handle. The catch bolt (15) abuts a catch means (22) in said neutral position, said catch means being accessible via a second opening (28) in the front wall (11). The catch means is displaceable from its catch position by manipulation from the outside via the second opening (28). Further, after said manipulation of the catch means (22), the catch bolt is displaceable with its bolt head (17) out of the non-circular opening (16) to the outside of the lock, enabling a turning of the catch bolt around its longitudinal axis.
