<p>The frame has a supporting frame (2), and a mounting base (3) forming a mounting surface for glass panes. The mounting base is supported at a horizontal rotational axis (5) running in a longitudinal direction of the frame, and foldaway from an opened position to a closed position in the direction of the supporting frame. An installation shoulder (4) is supported at another horizontal rotational axis (6), where the latter axis is shifted upward relatively opposite to the former axis.</p> |
