ABSTRACT:
A door lock comprises a reciprocatingly movable lock bolt and means for locking the lock bolt in a protruding position, for keeping the lock bolt in a withdrawn position and for operating the lock bolt either with a handle or the like or with a key operated mechanism. There is also a lock function selector for selecting a desired type of functional capacity for the lock. The lock function selector has three different setting positions, of which each determines a specific type of functional capacity for the lock. There is a setting member, preferably in a hidden position when the lock is mounted in a door, by means of which setting member the setting of the lock function selector can be restricted in order to further determine the types of function obtainable by the lock.
