Automatic opened window wing for use during power failure, has slewing mechanism whose lower ends are arranged in mass gravity axles between window blind frames and window wing, where axle points lie in direction of opening position

摘要

The window wing (F-FI) has a slewing mechanism (SW-A) whose lower ends are arranged in mass gravity axles between window blind frames (F-BIr) and a window wing, where the window wing is mounted in upper and lower axle points (SW-A o, SW-A u), and/or is pivoted in a tilting position. The axle points lie in a direction of an opening position in front of the mass gravity axles and/or gravity axles of the window wing. The gravity axles are pivoted around the wing, and a locking profile (V-Pr) with the frames are arranged on the lower ends of the mechanism to ensure tightness of a closed window.
