Abstract
Description
- In living rooms under an inclined roof it is known to make use of windows with a main frame and a glass-carrying reversible sash that is mounted in an intermediate frame, top-hinged in the main frame, and in its closed position seals against outwards facing abutting faces in the main frame. By means of releasable coupling fixtures the reversible sash may be secured to the intermediate frame and is then operable as an ordinary, outwards opening roof window, i.e. it may be opened and closed by pivoting about the top hinge axis.
- Opening the glass-carrying sash produces not only a rectangular aperture between the lower members of the sash and main frame but also triangular apertures between their side members. When the sash is opened for airing, for
instance 15° to 20°, it prevents in many cases rain from coming in through the rectangular aperture, but even at moderate wind, rain may frequently pass through one of the triangular apertures and the window should therefore be kept closed in rainy weather or in case of rain forecast. - A proposal for solving this problem is disclosed in US patent No.4,663,905 which in its abstract illustrates a skylight assembly with a bottom-hinged inwards opening sash and in which each of the sash side members extending in the height direction of the roof is tightly connected with one edge of a flexible, accordion-folded gusset portion, the opposite edge of which is sealingly connected with the roof. In the opened position of the window the gusset portion covers the actual triangular opening.
- For bottom-hinged windows with an inwardly opening sash it is known from US-A-2,392,678 to provide triangular or wedge-shaped inwardly projecting main frame side members with guide strips extending a short distance upwardly from the sill to form abutment means for the sash in its inwardly opened position.
- The object of the present invention is to provide a window with an outwardly openable sash which in spite of a simple structure eliminates the risk of rainfall through windows of this type, i.e. windows including a main frame for installation in an inclined roof and an outwardly opening sash that is top-hinged in said main frame, and for which abutment faces are provided on the inner side of the side members of the main frame.
- The window according to the invention differs from the prior art windows in that the main frame side members besides a set of outwards facing abutment faces for the closed sash also include inwards facing abutments, comprising abutment faces which are substantially parallel to the external plane of the main frame and extend throughout the length of the window sash to permit tightening engagement of the external surface of the window sash in the opened position thereof.
- Like in prior, top-hinged roof windows the hinge axis may advantageously be located substantially in the plane of the roofing and if it is desired to prevent the main frame from protruding considerably in relation to the roofing (as is for instance the case with so-called single pitch skylights), also the inwards facing abutments of the main frame must consequently lie mainly in the same plane. This means that the sash by normal operation remains within the main frame thickness (the height of the main frame perpendicular to the roof surface) and, therefore, the above-mentioned, triangular apertures will not occur. Another consequence is that the sash in the closing position has a steeper inclination than the roof proper, but this may in itself constitute an advantage, on one hand, from an architectural point of view and, on the other hand, because the outer glass surface will then to a smaller degree retain dust and dirt. Moreover, the view out of the window may be improved.
- The omission of the triangular apertures in the opened position of the window further simplifies the solution of another problem, viz. the provision of a protection preventing insects from flying in through the window opened for airing. This only requires the mentioned rectangular aperture to be shielded which is easily complied with by mounting an insect net in this aperture. If such a net is carried by a stable frame, this frame may as well be used to or contribute to firmly holding the window sash against the inwards facing abutments and may further make it difficult to get access from outside to the operating means positioned internally of the sash, thereby reducing the risk of burglary.
- The omission of the triangular apertures at opened sash entails that the airing effect in certain cases becomes smaller than desired, but this may be remedied in that the window sash may further be displaceable downwards and transversely of the top hinge axis. Such a downwards displacement of the sash in relation to the main frame causes an extra aperture between the sash and the top member of the main frame, thereby increasing quite considerably the airing effect and this extra aperture may, if desired, be protected in a simple manner against rain and insects coming in.
- A particular embodiment of the window with a sash displaceable in this manner is characterized in that the top and bottom edges of the sash from the closing position are displaceable parallel to the outwards facing abutment faces of the main frame and approximately horizontally outwards from said faces, resp., until the sash occupies a position substantially parallel to the external surface of the main frame so that the sash by swinging about an axis along one main frame side member gets clear of the inwards facing abutment on the opposite main frame side member. The latter condition means that the distance from the pivot axis to the opposite edge of the sash in the downwards displaced position thereof is shorter than the shortest distance from the same axis to the abutment on the opposite main frame side member. This may be obtained without difficulty by suitably dimensioning the window.
- In this embodiment the sash is actually openable in the same manner as an ordinary, side-hinged window and this offers the specific advantage that the aperture surrounded by the main frame in case of need may serve as exit, e.g. in emergency situations.
- Further details of the invention according to the last mentioned embodiment will appear from the following description with reference to the drawings, in which
- Fig. 1 illustrates the window, viewed from outside, the sash being in downwards displaced and fully open position,
- Fig. 2 is a vertical centre section, illustrating the sash in closed position (solid line) and in two different, openend positions (dotted line), respectively,
- Fig. 3 is a broken section analogous with Fig. 3, on a larger scale, and
- Fig. 4 is a detail as marked by the arrow indication in Fig. 3.
- Fig. 1 illustrates a section of a roof provided with any arbitrary roofing 1 and in which a
main frame 2, Fig. 2, is installed in an ordinary manner. This frame comprises atop member 3, a bottom member 4 and two side members 5, which together form an outwards facingabutment surface 6, with which a window sash 7 consisting of a frame with one or more layers of glass is in sealing contact, for instance via a gasket, when the window is closed. -
Main frame 2 includes an ordinary flashing 8 overlying the roofing 1 and, likewise in an ordinary manner, it is provided with internal panel members 9, Fig. 2. It appears, moreover, from this figure that the plane of theabutment face 6 has a somewhat greater inclination than the roof surface, while the upper or outer edges of the main frame side members 5 are parallel thereto. On the inner surface the main frame side members are provided, along said upper or outer edges, with projecting strips or rails 10 forming inwards facing abutment faces 11 for cooperation with the external surface ofsash 7. This sash is provided with top hinges 12 permitting the sash to be pivoted between the closed position and an airing position 7' in which it is kept tight against the underside of the strips 10, e.g. by means ofspring clips 13, thereby preventing rain from coming in at the window sides, while airing may still take place through therectangular aperture 14 between the sash 7' and the main frame bottom member 4. If desired, this aperture may be covered with a detachable or collapsible net that makes the window "insect-tight". - In the illustrated embodiment the window may also be opened in another way, viz. by a downwards displacement of
sash 7 in relation tomain frame 2 to the position marked 7" in Fig. 2. In this respect the top hinges 12 must be releasable and may thus, as best illustrated in Fig. 3, be constituted by a pair of ball-shaped or cylindrical bearingmembers 15 positioned at a respective one of the upper corners of the window sash and which in the dotted line position are in snap engagement with associatedbearing sockets 16 on the main frametop member 3. Similar bearingmembers 17, Fig. 3, are positioned at a respective one of the lower corner of the sash, and for cooperation therewith the main frame is provided withslide grooves 18 extending somewhat obliquely outwards from the main frame bottom member 4 towards the roof surface. After thetop bearing members 15 have been pulled clear of thebearing sockets 16 as illustrated in solid line in Fig. 3, thesash 7 is solely carried by thebearing members position 7" that may be determined by suitable stops. Both thebearing sockets 16 and theslide grooves 18 may includeramplike portions 19 which by the intitial downwards displacement raises thesash 7 slightly from theabutement face 6, thereby protecting a possible packing or gasket thereon against wear. - From the displaced
position 7" the window sash may, as explained above and as illustrated in Fig. 1, be swung open in the same manner as a side-hinged window, the pivot axis being then determined by the said two bearingmembers main frame 2, aguide rail 20 may be provided on the main frame side member at the hinge side, Figs. 3 and 4. This guide rail is parallel to theabutment face 6 and is connected with thetop bearing member 15 through a pivot joint oflink 21. If the side hinge function is abstained from, such a slidable retaining of the window sash may be used at both sides thereof. In order to tighten and lock the closedwindow sash 7 it may include arotary catch 22 at either side, see bottom of Fig. 3, connected with acommon handle 23 which in the position illustrated in solid line cooperates lockingly with apin 24 mounted in the main frame side member, while in a second position, illustrated in dotted line, said catches let off the pin, thereby allowing the window to open. The active edge of the catches may further be shaped so that by the initial rotation away from and the final rotation into the locking position it draws thebearing members 15 out of and presses them into the associatedbearing sockets 16.
