Abstract

Abstract A window closure assembly includes a window frame and a venetian blind section having a frame which is pivotally mounted at its upper edge within the window frame so that it may be moved to positions within and without the window frame. Operating means for the venetian blind louvers permit them to be selectively moved to open, closed, raised and lowered positions. Double glass doors are hinged to the side members of the window frame and may be moved to open or close the entire window.
