<p>The frame i.e. blind frame (1), has a perpendicular vertical post (2) for dividing the frame into two fields (2a, 2b). A fixed wing (4), firm glazing or a wing to be opened are attached in one field. The other field is open against the former field, and another blind frame (3) has a continuous field (3a), where a sliding wing (5) is arranged in the latter field of the former frame. The former frame is adjustable from an open position before the former field and into a position closing the latter field. The perpendicular vertical post is designed as a center post. An independent claim is also included for a method for operating a window or a door.</p> |
