Abstract

An auxiliary bolt arrangement in a door lock comprising a lock casing (1), which is provided with a latch bolt (3) spring-loaded to a protruding position and with an auxiliary bolt (5) spring-loaded to a protruding position for controlling the operation of the latch bolt and in which the latch bolt (3) has at least two different protruding positions with different extent of protrusion, whereby the auxiliary bolt arrangement is adapted to control the latch bolt (3) so that it allows the movement of the latch bolt (3) to its outermost protruding position only in case both the latch bolt (3) and the auxiliary bolt (5) are first moved into their retracted positions in the lock casing (1). The auxiliary bolt arrangement includes a restraining member (9), which the auxiliary bolt (5) in its protruding position is arranged to press against the force of a spring (10) to a position, in which the restraining member (9) prevents the movement of the latch bolt (3) to its outermost protruding position. In addition, the latch bolt (3) is adapted to retain the restraining member (9) in said position, if solely the auxiliary bolt (5) is being pressed inside the lock casing (1).
