Zusammenfassung: | The mechanism to open and close a panel in relation to a frame member, especially for a swivel and/or tilting window, has a drive unit (5) to operate a drive take-off (4). The drive movement has an idle stroke in relation to the take-off, and a working stroke acting on the take-off. The connection between the drive and the take-off incorporates a lock (11) to give a release link between the drive and the take-off at the end of the idle stroke movement. The drive is a nut moved by a rotating threaded spindle (6). An additional carrier (10) locks the panel at the frame. |
