1. A locking device (1), comprising:
a latch bolt arrangement (2), which is movable into at least a first and a second latch bolt position, said latch bolt arrangement (2) comprising a first follower arm engagement part (7);
a first follower arrangement (8) configured for directly transferring motion to the latch bolt arrangement (2) from a first unlocking device connected to the first follower arrangement (8), wherein said first follower arrangement (8) comprises a first follower arm (11) which comprises a latch bolt engagement part (13) which is configured to at least in some positions of the first follower arm (11) contact the first follower arm engagement part (7) of the latch bolt arrangement (2), whereby the latch bolt arrangement (2) can be pushed by a movement of the first follower arm (11) such that the latch bolt engagement part (13) pushes the first follower arm engagement part (7) such that the latch bolt arrangement (2) is moved from the first latch bolt position to the second latch bolt position; and
a locking arm (15) comprising a blocking part (17) which locking arm (15) can be positioned in at least two locking arm positions wherein in a first locking arm position the blocking part (17) locks the latch bolt arrangement (2) in the first latch bolt position and in a second locking arm position the blocking part (17) does not lock the latch bolt arrangement (2),
wherein said locking arm (15) further comprises a locking arm catch (19), whereby said locking arm (15) can be moved from the first locking arm position to the second locking arm position by pushing said locking arm catch (19),
the first follower arm (11) further comprises a locking arm catch engagement part (21) which will push the locking arm catch (19) for moving the locking arm (15) towards the second locking arm position when the first follower arm (11) is moved for pushing the latch bolt arrangement (2) to the second latch bolt position,
said locking device further comprising a second follower arrangement (30) configured for transferring a movement of a second unlocking device to the first follower arm (11) of the locking device (1),
said second unlocking device is a device which can be connected to the second follower arrangement (30) for unlocking the locking device,
said second follower arrangement (30) comprises a second follower arm (31) which comprises a second first follower arm engagement part (33) which in some positions of the second follower arm (31) is in contact with a second follower arm engagement part (35) of the first follower arm (11) for transferring motion of the second unlocking device through the second follower arm (31) to the first follower arm (11) for transferring the latch bolt arrangement (2) from the first latch bolt position to the second latch bolt position,
the first follower arrangement (8) comprises a cylinder follower (9) configured to act on the first follower arm (11),
said second unlocking device is a handle connected to the second follower arrangement (30),
whereby a turn of the handle is translated to a movement of the second follower arm (31) which is directly transferred to the movement of the first follower arm (11), and
said first follower arrangement (8) is configured to act directly on the latch bolt arrangement (2) without engaging said second follower arrangement (30).
