摘要

The skylight has a locking mechanism where the window pane (DFlr) is coupled to the carrier arm (TA) to give a choice of positions. The locking unit (VL) gives a choice of positions where the window is tightly against the frame or is at a gap from it for ventilation, with the window locked in each selected position.
