Abstract: A window to be used as a skylight or a front window and comprising a frame (1) and two window wings (2, 3) situated above one another on the outside of said frame and being pivotably openable about mutually parallel, especially horizontal axes (17, 18), and which in their open positions can be situated closely below one another in the upper opening of the frame. The two window wings (2, 3) are mutually separated and separately movable and are positioned completely outside the frame (1) both in their closed as well as in their open positions.In this manner a window is obtained which is inexpensive to manufacture and which allows many adjustment possibilities including a completely open position with a clear view and a great emergency exit, and where the loads on each wing are relatively insignificant.

Abstract: In a hinge device for tiltable windows, the base plate of the sash portion is provided with a pivot pin journalled in a guide member which is connected to the base plate of the frame portion in such a manner as to be mainly translatorily displaceable in relation thereto, whereby the pin during the initial opening movement of the window is moved downwards and outwards in relation to the frame portion. The sash portion of the hinge is also provided with a guide pin which by co-operation with guiding members on the frame portion co-ordinates the tilting movement of the sash portion about the pivot pin with the movement of displacement of the pin with a view to obtain a sash movement allowing outer covering elements to be arranged with an efficient overlapping relationship in the hinge area. By maximum displacement of the pivot pin the guide pin clears the guiding members so that the sash is free to tilt further in the opening direction while a stop prevents a rearward displacement of the guide member.
