Claims

1. Mortise lock ( 1 ) with a latch ( 4 ) standing in the extension direction (16 → 15) under spring preload ( 5 ), which is moved from its extended position ( 15 ) into its retracted position ( 16 ) as follows:
on the one hand via a first gear coupling from the arm ( 7 ) of a follower ( 6 ) and
on the other hand via a second gear coupling via a lock bit ( 10 ) of a lock cylinder ( 9 ) acted upon by change ( 11 ), the change sel ( 11 ) being shifted from a lower position ( 31 ) when the key is turned in the opening direction into a unlocking position is that he shifted with his gear Lich to the trap ( 4 ) changing end ( 14 ), the trap ( 4 ) in its retracted position ( 16 ), and with
a trap locking device ( 17 ), consisting of egg ner return lock ( 18 ) at the change ( 11 ) and a be in the return path ( 24 ) of the return lock ( 18 ) can be moved lock stop ( 19 ) for fixing, if necessary, the trapped by the key le ( 4 ), characterized in that the ratchet stop ( 19 ) is seated on a actuating element actuated by the follower nut ( 21 ), which has a run-up surface ( 22 ) for an associated nut follower cam ( 23 ) in the rotary region of the nut follower ( 6 ), and that
the lock stop ( 19 ) in the follower position "Fal le ( 4 ) in the retracted position ( 16 )" while at the same time holding the key retracted into the return path ( 24 ) of the return lock ( 18 ) and then with the key turned back and then the released follower ( 6 ) is prevented from returning to its basic position ( 33 ) by the return lock ( 18 ).

2. Mortise lock according to claim 1, characterized in that the run-up surface ( 22 ) on the associated pusher nut cam ( 23 ) abuts with a retention force.

3. Mortise lock according to claim 2, characterized in that the retention force is generated by a spring ( 26 ).

4. Mortise lock according to claim 3, characterized in that the spring ( 26 ) also acts upon the change ( 11 ) in the direction of the locking bit ( 10 ).

5. Mortise lock according to one of claims 2 to 4, characterized in that the return lock ( 18 ) with displacement of the change ( 11 ) with the locking beard ( 10 ) in the unlocking direction from the lock stop ( 19 ) and that the displacement element ( 21 ) is then reset under the reserve force ( 26 ) in the starting position ( 32 ).

6. Mortise lock according to one of claims 1 to 5, characterized in that the Verlagerungsele element ( 21 ) below the follower nut ( 6 ) is pivotally gela gert.

7. Mortise lock according to claim 7, characterized in that the pivot bearing ( 30 ) sits on the lock bolt ( 8 ).

8. Mortise lock according to one of claims 1 to 7, characterized in that the change ( 11 ) and the displacement element ( 21 ) both essentially from the lock bolt ( 8 ) emerging to one side of the follower nut ( 6 ).

9. Mortise lock according to claim 8, characterized in that change ( 11 ) and displacement element ( 21 ) enclose the lock bolt ( 8 ) between them.

10. Mortise lock according to one of claims 1 to 9, characterized in that the relocation of the lock renanschlag ( 19 ) in the return path ( 24 ) of the return path re ( 18 ) only when the key and the follower ( 6 ) are actuated by Stop occurs.
