ABSTRACT:
An operator for keeping doors, windows, shutters, or preferably entrance doors in a closed position has operating elements housed within a casing attached to a bar. A rod, for instance an espagnolette rod, is operatively connected to the operating elements and arranged for maneuvering at least one bolt.
The operating elements include means for maneuvering a further bolt. A handle is arranged for rotation in opposite direction from a neutral position. In one direction in the first bolt is manoeuvred, and in the other direction the further bolt is manoeuvred.
The operator has a spring device for returning the first bolt to a retracted position as soon as the handle returns from the position thereof corresponding to an extended bolt, unless the return movement of the bolt is positively prevented, for instance by friction engagement with the striker plate.
