ABSTRACT:
The invention concerns a tilting-swinging roof window, in which the window sash (1) is held by two arms (3) mounted to pivot on the upper end of the casement (2). In the swinging movement, the window sash (1) is guided by swivel pins (12) slidable in grooves (9) on the side members (6) of the casing (2). In the tilted position, the sash (1) is tightly connected by the arms (3) to the upper end of the casement (2). The roof window is provided with an opening device, which, in the area of the longitudinal side members of the casement, requires little space, applies force to the window casing as uniformly as possible, and has parts which are largely integrated into existing components. Slides (4) under spring force are guided in tubular arms (3) and swivel-mounted spring arms (5) are located on the side members (6) of the casement (2) so that a plane through the bearings (10, 11) of the spring arms (5) in each case forms an acute-angled triangle with a plane through the bearings (20) of the tubular arms (3) on the casement (2), and the bearings 10.
