ABSTRACT:
A roof window whose installed frame has upper and lower horizontal members and obliquely sloping side members has a casement attached to the upper frame member by two links fastened by fixed pivot pins to the respective center portions of the side rails of the casement and to the two ends of the upper frame member. Slides on the side rails slide along the side members of the frame when the links pivot on the upper frame member while the casement pivots on the links. The casement may be locked to the links for joint movement about the pivot pins on the upper frame member toward and away from the closing position of the casement in which the casement closes the opening bounded by the members of the frame. The slides abuttingly engage the side members of the frame in the closing position of the casement and move away from the frame members when the casement swings jointly with the links away from the closing position.
