• that upon actuation of the recessed handle (12) in the door (10), via the angled control piece (19) and the at least one of a plurality of slides (17), the deadbolt (14) can be adjusted into the opening position of the door (10), and the door (10) is enabled to open;
• and
• the device with the recessed handle (12) can be built into the door in such a way that it assumes four different positions, each rotated by 90° from one another, and the recessed handle (12) can be swung toward the bottom, to the left, toward the top and to the right, out of the frame (11) that is joined to the door.
