The present invention relates to a roof window with a pane supporting frame structure consisting of horizontal top and bottom members connected by parallel side members, which are at least partially wood profiles which on the outwards facing sides are covered by weather-shielding covering members for sealing enclosure of the subjacent wood profiles on all surfaces protruding from the roofing, said covering members being connected with the wood profiles by means of engagement and securing means 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 for covering the top member, an interior glazing profile for covering a part of the upper edge of each frame side member facing the light-admitting area of the window, an exterior covering member for covering the part of the exterior side of each frame side member protruding from the roofing and the adjoining part of the upper edge of the frame side member, and a cap member overlapping the glazing profile and said covering member, the cap member being at the bottom secured to the lower part of the side member, whereas at the top it is secured to the upper part of the side member.
Roof windows of this type, both openable and not openable, are well known and are widely used for ensuring improved admittance of daylight when converting ceilings of buildings into rooms for accommodation and business purposes.
The purpose of using weather-shielding covering members, which may consist of comparatively thin metal sheet profiles, for instance of aluminium, or plastic profiles, is to provide, to the highest degree possible, a total exterior protection of the wood profiles in the top, bottom and side members of the main frame and sash structures.
In conventional embodiments of roof windows the covering members are typically secured to the wood profile members of the main frame and sash structures by means of screw connections which are screwed directly into the subjacent wooden parts, which in order to obtain a sufficiently exact mounting requires pre-bored screw holes in the wooden parts and has turned out to entail a risk of moisture or water penetration into the wooden parts, in particular through the screw holes in the covering members.
In openable roof windows, the covering members on the outwards facing sides of the side members of the main frame and sash structures typically comprise an upper and a lower cap member in connection with the upper part of the main frame side member above the pivot axis and with the lower part of the sash side member under the pivot axis such that the lower cap member may follow the swinging of the sash structure by opening of the window. In conventional windows it has in respect of these cap members turned out to be difficult to obtain a satisfactory sealing at the transition between the upper and lower cap members, and at the lower end of the lower cap members.
Attempts have been made to solve this problem by use of a roof window known from DE-A-24 43 098, in which covering members are secured to the main frame and sash profiles by engagement with shackles fastened to the profiles by screws or nails. However, this design makes it necessary to mount the covering members by sliding them on the main frame and sash profiles in the longitudinal direction thereof.
The object of the invention is to provide a system of covering members for a roof window with a fully closed enclosure of the wooden parts of the frame and sash profiles, the mounting being at the same time facilitated.
To meet this object, the roof window according to the invention is characterized in that the cap member is retained at its upper end at said top by said upper covering cap and is provided at said bottom with an integral bent, hidden engagement means for snapping engagement with an engagement means secured at the lower end of the side member.
In this way a particular good protection of the wood profiles against moisture or water penetration is obtained and the mounting is at the same time facilitated, the cap member being first slid under the upper covering cap and then connected with its lower end to the lower end of the side member by snapping engagement.
The invention may advantageously be used both in connection with not openable roof windows with a frame structure fixedly positioned in the roof structure and in connection with conventional, openable roof windows.
A preferred embodiment of such an openable roof window is according to the invention obtained thereby that the sash structure has a pivot axis parallel with and approximately halfway between the top and bottom members, and that said cap member comprises an upper and a lower cap member placed on either side of the pivot axis, the upper cap member being secured to the upper part of the main frame side member or to an intermediate sash arm connected between the frame and sash side members, whereas the lower cap member is secured to the lower part of the sash side member, said cap members being at a short distance from the lower end of the upper cap member and the upper end of the lower cap member provided with securing means for being secured to fittings in fixed connection with the main frame side members or said intermediate sash arms, respectively, and with the sash side members, but positioned outside of the wood profiles thereof.
Further advantageous embodiments of the roof window according to the invention and the accompanying covering members are stated in the subclaims.
The invention will now be explained in detail in the following with reference to the schematic drawing, in which
In the embodiment shown in
By means of swing fittings 9, known per se, between the frame and sash side members 3, 4 and 7, 8 the sash structure is pivotally journalled in the frame structure with an axis of rotation 10 parallel with the top and bottom members and substantially halfway between them.
The top, bottom and side members of the frame and sash structures are for the major part built up by wood profiles which on all surfaces that are exposed to the weather are covered by covering members which, in the embodiment shown, are constituted of comparatively thin metal sheet profiles, for instance of aluminium, and which together provide a completely weather-shielding enclosure of the window.
Thus, the frame side members 3 and 4 are covered by elongate covering members 11, with a substantially Z-shaped cross section comprising a sidewall 11a covering an upper part of the outwards facing side surface of the frame side member positioned outside the roofing perpendicular to the roof surface, in which the window is mounted, an upper wall 11b covering the adjacent upper edge of the frame side member, and a comparatively low flange wall 11c protruding from the upper wall.
The frame bottom member 2 is covered by an elongate covering member 12 with substantially L-shaped cross section and comprising a bottom wall 12a covering the underside of the frame bottom member perpendicular to the roof surface, and an upper wall 12b covering the adjacent upper side of the frame bottom member.
To establish a tight connection at the transition between the two frame side covering members 11 and the frame bottom covering member 12, the side covering members 11 are at their lowest ends provided with engagement flanges 13 in form of bent exterior parts of the sidewalls 11a for engagement with protruding flange members 14 from the ends of the bottom covering member 12.
The frame covering members 11 and 12 are connected with their respective frame profiles 3, 4 and 2 by means of screws which are preferably screwed into the upper edges of the frame profiles, as explained in detail in the following with reference to
In the sash structure the top and side members are covered by an interior glazing profile 15 facing the pane area of the window and having an inwards protruding glazing profile 15a which via an intermediate sealing strip abuts the edge of the pane member 16 of the window, said pane member being typically a 2 or 3 layer sealed glazing unit. In continuation of the glazing profile flange 15a, the glazing profile 15 comprises along the edges of the double pane 16 a substantially U-shaped profile member with an upright flange wall 15b, which on the sash side members 7 and 8 follows the low flange wall 11c of the covering members 11 on the frame side members 3 and 4.
Correspondingly, the sash bottom member 6 is covered by a substantially L-shaped covering member 17 with a glazing profile 18 here covering the entire upper side of the sash bottom member 6, and by an underlying wall 19 covering the underside of the sash bottom member and overlapping the covering member 12 on the frame bottom member 2.
The parts of the covering members 11 and the glazing profiles 15 positioned on the top side of the frame and sash side members are on each side overlapped by the axis of rotation 10 of an upper cap member 20 and a lower cap member 21, respectively. These cap members are designed as flat, trough-shaped profiles with identical, substantially U-shaped profile cross section comprising an exterior wall 20a, 21a and two low side walls 20b, 21b and 20c, 21c covering the low upright flange walls 11c and 15b on the covering member 11 and the glazing profile 15, respectively.
As will be seen from
At the same time the joggling of the connection member 22 ensures that the lower cap member 21 secured to the sash side member 7, 8 by opening of the window as shown in
As will be more clearly seen from
In the embodiment shown, the lower cap member 21 is manufactured by a pressing operation such that the side carriages 21b–c at the bottom are shaped in one piece with a bottom wall 21d with smooth corners. This kind of closing contributes to the attractive appearance of the window and provides a good protection of the lower parts of the sash side members 7 and 8 against the weather.
The upper and lower cap members 20 and 21 are according to the invention connected with the respective frame and sash side members 3, 4 and 7, 8, respectively, such that they are easy to mount with great accuracy and moreover easy to dismount, the moisture influence on and water penetration into the wooden parts of the frame and sash side members being substantially prevented.
The upper cap member 20 is thus secured by a connection member 23 at its upper end solely by an upper covering member 32 for the frame and sash top members 1 and 5 against a support member 24, which in the embodiment shown is secured to the top side of the frame side member 3, 4.
The lower cap member 21 is at its lowest end provided with an engagement means which in the embodiment shown has the shape of an engagement bracket protruding from the bottom wall 21d and being parallel with the exterior wall 20a, said bracket having a keyhole-shaped recess 26 for engagement with and retainment of a tap member 27 secured to the covering member 17 on the sash bottom member 6.
At their opposite ends the upper cap member 20 and the lower cap member 21 are provided with securing means in the form of screw holes 28 for screws 29 to be screwed into screw fittings 30 and 31, which in the embodiment shown are connected with the frame and sash side members 3, 4 and 7, 8 outside the wood profiles thereof.
The screw fittings 30 and 31 may advantageously be made of plastic material and secured to those parts of the swing fitting 9 which is connected with the frame side member 3, 4 and the sash side member 7, 8, respectively. In this way it is not necessary to drive fastening screws into the wooden parts of the frame and sash side members.
At the top members 1 and 5 of the frame and sash structures the enclosure of the window is finished by the substantially hood-shaped top cap 32, which in the embodiment in
In
To make it possible to swing the window sash approximately 180° to a convenient cleaning position, the sash structure 33 is moreover pivotally connected with an intermediate sash with sash arms 36, which in the closed position of the window are positioned between the upper parts of the frame and sash side members 2, 4 and 7, 8, respectively, and which during normal use of the window as a top-hung turning window follow the sash side members. The axis of rotation of this swingable connection lies approximately halfway between the top and bottom members in the same manner as shown in
As this double pattern of movement entails that the upper part of the sash both during normal use as a top-hung window must be pivotable outwards relative to the frame and, at said swing movement to a cleaning position, has to be swingable inwardly relative to the frame in the same manner as shown in
In the embodiment shown in
The above design and mounting of the upper and lower cap members 20 and 21 provide a particular good protection of the wooden parts of the sash profiles and the other wooden parts of the frame profiles not covered by the other covering members, i.a. as a consequence of the fact that fastening screws for the caps are not screwed into the wooden parts.
As shown in
For further safeguarding of the screw connection an upright collar 48 may be provided in the bottom of the head portion 42 of the bushing or several upright flaps serving as washer plate against the countersunk edge area 43 ensuring that the screw head cannot be screwed over and deform the covering member 11.
