The invention relates to a system (1) for operating a lock (2), comprising a functional support (6), in particular a frame, a door operating part (7), in particular a door handle, a bearing element (8), which is connected to the functional support (6) in a rotationally fixed manner and which is used to support the door operating part (7) on the functional support (6), and a coupling, which comprises at least one coupling element (15), which can be moved from a position in which the coupling element is not in contact to a position in which the coupling element is in contact with a coupling counter element (3) integrated in the lock (2), wherein in the position of the coupling element (15) in which the coupling element is not in contact with the coupling counter element (3), the door operating part (7) can be freely rotated without transferring a torque to the lock (2), and wherein in the position of the coupling element (15) in which the coupling element is in contact with the coupling counter element (3), a torque applied to the door operating part (7) can be transferred by means of the coupling element (15) to the coupling counter element (3) and by means of the coupling counter element to the lock (2), wherein the coupling element (15) is integrated in the bearing element (8) at least in the position in which the coupling element is not in contact.
