Abstract:
A roof window with a frame structure and an openable, pane supporting sash structure, both having horizontal top and bottom members (1, 2; 5, 6) connected by parallel side members (2, 4; 7, 8), the sash structure being accommodated in the frame structure as a pivot sash with a pivot axis (10) parallel with and approximately halfway between the top and bottom members (1, 2; 5, 6), whereby the top, bottom and side members (1-8) of the frame and sash structures at least partially are designed as wood profiles which on the outwards facing sides are covered by weather-shielding covering members (11, 12, 15, 17, 20, 21, 32) for sealing enclosure of the subjacent wood profiles on all surfaces protruding from a roofing, said covering members being connected with the wood profiles in the top, bottom and side members of the frame and sash structures by means of engagement and securing means (23-29, 40) which are designed in such manner and/or positioned such relative to the covering members that penetration of water and moisture into the wood profiles is substantially prevented, the covering members comprising a hood-like upper covering cap (32) for covering the top members (1, 5) of the frame and sash structures, an interior glazing profile (15) for covering a part of the upper edge (7, 8) of each sash side member facing the light-admitting area of the window, an exterior covering member (11) for covering the part of each frame side member (3, 4) protruding from the roofing of the exterior side and the adjoining part of the upper edge of the frame side member, and an upper and a lower cap member (20, 21) overlapping the glazing profile (15) and the frame covering member (11) on each side of the axis of rotation (10), and of which the lower cap member (21) is secured to the lower part of the sash side member (7, 8), whereas the upper cap member (20) is secured to the upper part of the frame side member (3, 4) or to an intermediate sash arm (36) connected between the frame and sash members (3, 4; 7, 8) and positioned above the pivot axis, characterized in that said cap members (20, 21) are designed as flat, trough-shaped profiles with the same substantially U-shaped profile cross section comprising an exterior wall (20a, 21a) and two low side walls (20b-c, 21b-c) covering upright flange walls (15b, 11c) on the glazing profile (15) and the frame covering member (11), respectively, such that, in the closed position of the window, the exterior walls (20a, 21a) and side walls (20b-c, 21b-c), respectively, of the cap members (20, 21) are flush with each other, the lower cap member (21) being provided at its upper end with a joggled connection member (22) inserted under the lower end of the upper cap member (20) to permit unimpeded outwards swinging of the lower cap member (21) relative to the upper cap member (20) in the open condition of the window.
