ABSTRACT:
A turnable window arrangement has a window sash to be rotated about a horizontal axis through approximately 180.degree. relative to a window frame. The window frame is provided with a separately removable screen secured to the frame in a position inside the swinging path of the sash. A regulating arm is arranged to pass through the window frame in order to effect the opening and closing operations of the window sash. A separate lock element is used to lock the regulating arm and thus the sash, in any preselected position relative to the window frame between completely closed and opened venting positions.
