(57) Lock device comprising a lock housing (1) which houses: a lock bolt (40) which is
movable between an unlocked position and a locked position, a first follower (10),
a second follower (20), and a blocking member (62) which is coupled to the first and
to the second follower and which, by means of each of the first and second follower,
can be manoeuvred between a blocking position, in which the lock bolt is blocked in
its locked position, and a release position, in which the lock bolt is movable to
the unlocked position. A latch device (80) is adjustable between a latching state,
in which manoeuvring of the blocking member by means of the second follower from the
blocking position to the release position is blocked, and a non-latching state, in
which manoeuvring of the blocking member by means of the second follower from the
blocking position to the release position is permitted. The latch device (80) is designed
such that, when the lock bolt (40) is located in its locked position and the latch
device has adopted its latching state, by mechanical cooperation with the lock bolt,
the latch device is blocked against being adjusted from its latching state to its
non-latching state.
