A door lock, which comprises a lock casing 1 provided with a post 2, and in which there is a falling bolt 3 and a latch 4 which are both spring-loaded 6, 7 towards their projecting positions, a first function spindle 9 to which key-operated function means can be connected, and a second function spindle 10 to which a trigger, a knob or the like can be connected, and an auxiliary bolt 5 which, in the open position of the door, is normally arranged to prevent displacement of the latch 4 to its outward position. According to the invention, the lock casing 1 is provided with a guide plate 15 which cooperates with both the falling bolt 3 and the latch 4 and which comprises a first guide groove 18 which is arranged to guide a pin 19 or the like on the latch, so that together they prevent movement of the latch 4 from its inward position to its outward position until the falling bolt 3 has been moved to a position near to its outward end position. <IMAGE>
