Abstract
A door lock includes a latch bolt and an auxiliary bolt. A stop member is supported by the auxiliary bolt and is movable relative to the auxiliary bolt between a position in which it prevents a guide element moving to a position providing deadlocking of the latch bolt, while the auxiliary bolt is in a protruding position, and a position in which it allows the guide element to move to a position providing the deadlocking of the latch bolt. The stop member allows the guide element to move to the position providing deadlocking of the latch bolt only in case both the auxiliary bolt and the latch bolt are first moved to retracted positions.
