  • Patent number: 5581941
    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.

  • Patent number: 5581942
    Abstract: A connecting assembly for installing the sash of a house skylight to the sides of its casement, has connecting parts that can pivot relative to each other, and the casement has holding elements that have cross sections which will engage therewith. This assembly allows the window sash to be inserted from the interior rapidly and in a simple manner by engagement with the positioning arms on the casement. This is achieved by the connecting parts (3) having a U-shaped cross section (4), which accept swinging positioning arms (5) which serve as the holding elements, and these connections can be locked by self-engaging attachment elements (6) that can be engaged without tools.
