Foldable swinging skylight has window framework having locking component and propping component that engage locking device on window frame when window framework is in closed position and cleaning position, respectively

摘要

A locking component on a window framework (4) engages a locking hole on a locking device (10) on a window frame (2) when the window framework is in a closed position. A propping component (30) on the window framework engages the locking hole of the locking device when the window framework is in a cleaning position. The window framework is movable relative to the window frame between open and closed positions through a folding framework (6) turnable about an axle (A1). The window framework is tiltable about an axis of rotation between the open position and the cleaning position.
