-16- Abstract A turnable window arrangement has a window sash to be rotated about a horizontal axis through approximately 180° relative to a window frame. The window frame is provided with a separately removable air screening filter secured to the frame in a position inside the swinging path of the sash. A link arm mechanism is arranged to lock the sash in different positions between completely closed and opened venting positions. The mechanism comprises a socket member connected to the sash and a link arm pivotally mounted at the outer end of a support arm protruding from the socket member. A pivoting of the link arm is allowed about a first axis extending laterally of the support arm. The support arm is arranged to penetrate through a guide opening in a lock member secured to the frame in a position circumferentially outside of the screen filter to allow free and unprevented movement of the link arm at an inwards facing side of the frame. The link arm and support arm are pivotable about a second axis axially of the support arm to allow pivoting of the link arm between open and closed positions. A minor pivoting is also allowed between the support arm and the link arm when moving the window sash into different venting positions. The link arm is -17- provided with a number of arresting means extending laterally of the link arm for cooperation with an adjustable locking pin in the locking member.
