(57) Lock device comprising a lock housing (10, 210), in which there is arranged: a lock
bolt (30, 230), which is movable between an unlocked position and a locked position,
and a first follower (50, 250). A driver (60, 260) is coupled to the first follower
and is arranged to, by means of the first follower, manoeuvre the lock bolt between
its unlocked and locked position, as well as, in the locked position of the lock bolt,
to dead lock the lock bolt by contact against the lock bolt. A second follower (70,
270) is arranged to, by rotation, influence the functioning of the lock device. A
blocking mechanism (100, 300) is switchable between a blocking state, in which rotation
of the second follower is barred, and a non-blocking state, in which rotation of the
second follower is allowed. The blocking mechanism (100, 300) is arranged to, when
the lock bolt (30, 230) is in its locked, dead locked position and the blocking mechanism
has assumed its blocking state, by mechanical interaction with the driver (60, 269),
bar the blocking mechanism from being switched from its blocking state to its non-blocking
state.
