In a mortise lock conforming to recent requirements and having an inner or an inner and an outer door handle and a rotary cylinder lock, the invention affords the advantage of complete security as a result of the automatic shooting forwards of the lock bolt when the door is slammed shut. The blocking of the door handle or door handles by button pressure prevents the possibility that children will leave the house without permission, or ensures complete security with a lock having two door handles, for example in office doors, etc. The use of a key for the secure locking of the door proves to have been overtaken. If the door handle is not blocked, the door can be opened by means of the door handle, otherwise the door is opened by the actuation of a rotary cylinder, the blocking of the door handle being cancelled at the same time. Furthermore, it can be seen that there is the advantage that the house owners, employees, etc. are compelled to withdraw the key, since automatic locking does not otherwise take place. The door is obviously open and the house owners, employees, etc. notice that the key is still inserted.
