ABSTRACT:
In a tiltable window, especially to be mounted in a sloping roof, the lateral members of the sash and frame carry external cover rail sections which in the closed position of the window overlap each other in the area of the hinge device of the window. The hinge device consists of a frame part and a sash part and of an intermediate part connected with each of the two parts by means of two parallel pivot pins which in the closed position of the window are situated within the outer side of the window and are protected by the cover rail sections. During the opening movement of the sash, its hinge part is first rotated in relation to the intermediate part while this part is locked to the frame part by means of a latch, and after the forcedly controlled release of the latch, the sash part and the intermediate part together can rotate further in relation to the frame part. During the first part of the rotation, an edge recess provided in the intermediate part gives room for the upper end of the cover rail section of the sash which thereby is disengaged from the lower end of the cover rail of the frame.
