Description

Description [0001] The present invention relates to a roof window according to the preamble of claim 1.

[0002] W02007/028590A2 discloses a roof window according to the preamble of claim 1.

[0003] Roof windows of this kind are known in a number of different configurations and have proven to function very well in a number of different uses. However, in the known windows the top sash module restricts the space available for the pane of the window, and thereby restricts the amount of light entering a building in which the window is mounted.

[0004] It is therefore an object of the present invention to provide a roofwindow, which providesforan increased light admitting area without compromising the provision of ventilation openings.

[0005] This is achieved with a roofwindow according to claim 1.

[0006] Thereby a roofwindow is provided with which the top sash module does not interfere with the space available for the pane of the window. Consequently the pane area is maximized and the amount of light entering a building in which the window is mounted is correspondingly increased.

[0007] Preferred embodiments and further advantages will be apparent from the following detailed description and the appended dependent claims.

[0008] The invention will be described in more detail below by means of a non-limiting example of an embodiment and with reference to the schematic drawing, in which

Fig. 1 shows a perspective view of a window according to the invention in the assembled state seen from below or inside,

Fig. 2 shows a perspective view of a window according to the invention in the assembled state seen from above or outside,

Fig. 3 shows an exploded view of the top of a window according to the invention featuring a top sash module according to the invention.

Figs 4 and 5 show views corresponding to Figs 1 and 2 showing a slightly different embodiment of the window according to the invention; and Fig. 6shows a partial perspective view of the window shown in Figs 4 and 5.

Fig. 1 and Fig. 2 show one embodiment of a window 1 according to the invention comprising a pane 4 defining plane, a frame 2 having a top member 5, a bottom member 6 and two side members 7, 8 defining a frame plane, and a sash 3 having a top member 9, a bottom member 10 and two side members 11, 12 defining a sash plane. In the embodiment shown, the window is centre-hung in that the sash 3 is connected to the frame 2 by a pivot hinge (not shown) provided between side members 7, 11; 8, 12 of the frame 2 and sash 3, respectively, to be openable by tilting the sash 3 of the window 1 about the pivot hinge axis 21 defined by the pivot hinge. The pivot hinge comprises two parts, namely a sash part and a frame part.

[0009] The hinges used are preferably of the type described in the applicant’s earlier patent applications W09928581 and GB1028251, where a curved member and a tap on one hinge part travels in a curved guide track in the other during opening and closing of the window. The radius of curvature entails that when using such hinges, the hinge axis lies at a small distance above the actual hinge parts and as the sash frame is turned first the curved member and then the tap comes out of the track. In combination this provides a pattern of movement which allows easy operation of a centre-hung window and allows the sash frame to be turned substantially entirely around.

[0010] As used in this description, a closed position of the window 1 means a position in which the frame plane and the sash plane coincide, that is form an angle of 0 degrees with each other. Similarly an open position of the window 1 as used herein generally means a position in which the sash 3 is tilted about the pivot hinge axis 21 such that the frame plane and the sash plane no longer coincide.

[0011] As seen in Fig. 1 a longitudinal axis 13 of the window 1 is defined as extending perpendicular to and between the frame top member 5 and the frame bottom member 6, a transversal axis 14 of the window is defined as extending perpendicular to and between the respective frame side members 7 and 8 and thereby perpendicular to the longitudinal axis 13 and a depth axis 15 of the window 1 is defined as extending perpendicular to both the longitudinal axis 13 and the transversal axis 14. The pivot hinge axis 21 and the transversal axis 14 are parallel, and are shown as coinciding in the figures.

[0012] The window 1 furthermore comprises at least one lock 17 of a type known per se for locking the frame 2 and sash 3 together as well as a generally circumferentially extending sealing 18 provided on the sash 3 for sealing the gap between the sash 3 and the frame 2 in the closed position of the window 1. The sealing 18 comprises at least one, preferably at least two sealing strips.

[0013] Notwithstanding the centre-hung window 1 shown in Fig. 1 the window according to the invention may in other embodiments be top-hung, with or without an intermediate frame structure, have the hinge axis somewhere between the top and the centre, be side-hung or for that matter even be bottom-hung.

[0014] The sash 3 and frame 2 of the window according to the invention may be made of wooden members or members made of castor extruded polyurethane (PUR).

[0015] Referring now to Fig. 3 the window 1 comprises in connection with the top member 9 of the sash 3 a top sash module 411 having a substantially rectangular cross section with a first side 412, a second side 415 opposite to and extending parallel with said first side 412, a third side 413 and a fourth side 414 opposite to and extending parallel with said third side 413. The third and fourth sides 413 and 414 extend substantially perpendicular to and connecting said first and second sides 412 and 415.

[0016] The first side 412 of the top sash module 411 is adapted to be attached to or abutting a surface of the top sash member 9 opposite the pane 4 of the window 1.

[0017] The side sash members 11 and 12 of the window 1 each comprise an extension 417, respectively 416, extending in the longitudinal direction 13 of the window 1 beyond the top sash member 9. The third and fourth sides 413 and 414 are connected to the extensions 416, respectively 417, of the side sash members 12, respectively 11. In this way the top sash module 411 is placed essentially outside the space defined by the sash 3, i.e. essentially outside the sash plane.

[0018] The connection between the third side 413 and the extension 416, respectively the fourth side 414 and the extension 417, may be achieved in any suitable way, such as by a friction-locking or snap-locking mechanism or even by means of an adhesive or an attachment means such as a screw or a nail.

[0019] In a preferred embodiment shown in Fig. 3, the third and fourth side 413 and 414 are each provided with an attachment member 435, respectively 438, while the extensions 416 and 417 are each provided with a corresponding receiving member437, respectively 439. In the embodiment shown, the attachment members 435 and 438 are protrusions provided with a slot 436, respectively 440, while the receiving members 437 and 439 are corresponding slots in the extensions 416 and 417. The slots 436, 440 provide the attachment members 435 and 438 with a spring-effect such that the attachment members 435 and 438 are retained in the receiving members 437 and 439 by means of friction. Such an arrangement provides for a particularly secure and strong attachment of the top sash module 411.

[0020] In another embodiment, being particularly suitable for roof windows in which the sash 3 and the frame 2 are made of plastic, preferably of PUR, the top sash module 411 is provided as an integral or separate part of the top sash member 9 and/or of the side sash members 11 and/or12. In this embodiment the top sash module is preferably placed substantially inside the space defined by the sash. Furthermore, in this embodiment the top sash module 411 is preferably made of a plastic, such as PUR. In case the top sash module411 is provided as a separate element it is preferably attached by means of a snap locking connection somewhat resembling the attachment members 435, 438 and the slots 436, 440 described above and shown in fig. 3, but where the slot is relatively wide, while the attachment members are provided as thin, flexible tongues.

[0021] As likewise shown on Fig. 3, the window 1 furthermore comprises a ventilation flap 400 in connection with the top sash member 9. The ventilation flap 400 is an elongate element, which is connected to the top sash member 9 by means of at least one pivot connection 401 such as a hinge and to the lock 17 by means of another pivot connection 406. The pivot connection 406, which may be a hinge, and the lock 17 are preferably adapted to enable the ventilation flap 400 to be placed in at least two, and preferably at least three, different positions including a closed and at least one open position. To this end the lock 17 may for instance be a spring biased locking mechanism. Although two locks 17 are shown in Fig. 3, only one lock or for that matter more than two locks may also be provided.

[0022] The ventilation flap 400 extends substantially in the total longitudinal extension of the top sash member 9. The ventilation flap 400 comprises a first profile 402, a second profile 403, two third profiles 404 and at least one fourth profile 404’.

[0023] The first profile is an elongate profile extending substantially in the total longitudinal extension of the top sash member 9 and being adapted for functioning as a handle for operating the ventilation flap 400. The first profile 402 may in principle have any cross-sectional shape, although a rounded, triangularshape is preferred.

[0024] The second profile 403 is likewise an elongate profile extending substantially in the total longitudinal extension of the top sash member 9. The second profile 403 is adapted for abutment against a top sash module 411, which will be described in closer detail further below, as well as optionally against the top sash member 9. To this end the second profile 403 may comprise a layer405 of a durable and flexible material suitable for sealing the transition between the second profile 403 on one side and the top sash member 9 and top sash module 411, respectively, on the other side. The layer 405 of flexible material may for instance be made of a suitable foam or felt and may comprise a reinforcing surface layer for added durability. The second profile 403 may in principle have any suitable cross-sectional shape, although a shape of which at least the surface comprising the layer 405 is substantially plane is preferred.

[0025] The second profile 403 furthermore comprises the pivot connection(s) 401, of which three are shown in Fig. 3 although any number may in principle be provided, connecting the ventilation flap 400 and the top sash member 9 as well as the pivot connection 406 connecting the ventilation flap to the lock 17.

[0026] The first and second profiles 402 and 403 are connected by means of the third and fourth profiles 404, 404’ in such a way that they extend substantially parallel to each other and that the handle, i.e. the first profile 402, for operating the ventilation flap is displaced in relation to the second profile 403 in a direction away from the top sash member 9 and towards the pane4 in the longitudinal direction 13 of the window 1.

[0027] More specifically, the third profiles 404 are located connecting end sections of the first and second profiles 402 and 403, while the at least one fourth profile 404’ is located connecting the first and second profiles 402 and 403 at a location between the end sections for supporting purposes.

[0028] In a preferred embodiment that may be seen on Fig. 3, the third and fourth profiles 404 and 404’ are curved in such a way that, when the first and second profiles 402 and 403 are connected by means of the third and fourth profiles 404 and 404’, the first profile 402 is arranged staggered with respect to the second profile 403, particularly staggered in the longitudinal direction 13 of the window 1.

[0029] In furtherdetail, the third profiles 404 each comprise a first surface 409, a second surface 410, a third surface 407 and a fourth surface 408. The first surface is adapted for abutting and connection with an end section of the second profile 403, particularly the outermost 5 mm or less of the second profile 403 seen in the longitudinal direction thereof. The second surface 410 is arranged opposite said first surface 409 and is adapted for connection with an end section of the first profile 402, particularly the outermost 5 mm or less of the first profile 402 seen in the longitudinal direction thereof. The mutually opposite third and fourth surfaces 407 and 408 are connecting the first and second surfaces 409 and 410. The third and fourth surfaces 407 and 408 are both curved, the third surface 407 having a smaller radius of curvature than the fourth surface 408. In this way the general shape of the third profiles 404 may be described as similar to that of e.g. a comma.

[0030] Similarly, the fourth profiles 404’ each comprise a first surface ( not visible on Fig. 3) adapted for connection with an intermediate section of the second profile 403, a second surface 410’ opposite said first surface 409 adapted for connection with an intermediate section of the first profile 402 and mutually opposite third and fourth surfaces 407’ and 408’ connecting said first and second surfaces 409’ and 41 O’. The third and fourth surfaces 407’ and 408’ are both curved, preferably in the same way as the third and fourth surfaces 407 and 408 of the third profiles 404, the third surface 407 having a smaller radius of curvature than the fourth surface 408.

[0031] The third and fourth profiles 404 and 404’ are preferably less than 5 mm, most preferred less than 3 mm, in thickness.

[0032] Providing the ventilation flap 400, and particularly the third and fourth profiles 404 and 404’, with a shape as that described in general terms above has the effect of providing more room for the hands of a user desiring to grip and operate the handle thus facilitating gripping and operating the ventilation flap 400. A further advantage of such a displacement will become obvious from the below description of the associated top sash module 411.

[0033] The profiles 402, 403, 404 and 404’ of the ventilation flap may be made of a metal, preferably aluminium, wood, plastic or polyurethane. In case of a wooden window 1, the first profile 402 is preferably made of aluminium, the second profile 403 of wood and the third and fourth profiles 404 and 404’ of plastic. The profiles 402, 403, 404 and 404’ are preferably assembled using an adhesive. In case of a window 1 made of extruded or cast PUR, all of the profiles are preferably likewise made of PUR, and may be cast separately or partially or fully integral.

[0034] When operating the handle, i.e. the first profile 402, the ventilation flap 400 is pivoted about the pivot connection 401 from an open position to a closed position in abutment against the top sash module 411 or vice versa. One or more intermediate positions, in which the ventilation flap 400 may be temporarily locked, may be defined between the open and closed position.

[0035] The top sash module 411 is furthermore provided with one or more ventilation openings 418. For ventilation purposes air is allowed to pass through the ventilation openings 418 when the ventilation flap 400 is in its open position, while the ventilation openings 418 are closed when the ventilation flap 400 is in its closed position abutting the top sash module 411. The amount of air passing the ventilation openings 418 may be regulated by means of the intermediate positions of the ventilation flap 400. In the closed position of the ventilation flap 400, the sash module 411 forms a sealing stop for the ventilation flap 400.

[0036] The top sash module 411 may furthermore be provided with at least one, preferably two, protrusions 434, which are arranged in connection with a ventilation opening 418. The protrusion(s) 434 is intended for acting as a guide means for an element 406’ connecting the pivot connection 406 and the lock 17. Although Fig. 3 shows an embodiment of a window 1 comprising two locks 17, another preferred embodiment of awindowfea-tures only one lock 17, which is preferably placed centrally on the top sash member 9, and correspondingly the top sash module 411 features only one, likewise centrally arranged, protrusion 434.

[0037] This arrangement has the advantage compared with the known solutions, that the ventilation arrangement provided by the top sash module 411 and the ventilation flap 400 in combination is positioned essentially outside the space defined by the sash members 9, 10, 11, 12. In other words, the top sash module 411 and the ventilation flap 400 are positioned in such a way as to enable the area available for the pane 4 to be increased, which in turn allows for a larger amount of light to be transmitted through the window into a building in which it is installed. Particularly, measurements have shown that this arrangement may increase the pane area by 8 to 9 %, particularly about 8 %. Another advantage provided with this arrangement lies in that the top casing 500 may be made smaller, which in turn saves material and thus provides for a window 1 which is cheaper to manufacture.

[0038] Preferably, the top sash module 411 is made of a plastic, such as PUR, and it may be cast or extruded. This has the further advantage of improved insulation characteristics compared with existing solutions. Preferably, the thickness of the top sash module 411 is between 1 and 2 centimetres. For windows 1 with a sash 3 and a frame 2 made of polyurethane, the top sash module 411 may be cast in one piece with the sash 3, but it may also be cast as a separate module such as that described above.

[0039] Furthermore, the top sash module 411 may be adapted to function as a holder for receiving a gasket or sealing strip for sealing the gap between the top sash module 411 and the top frame member 5 in the closed position of the window 1. To this end the second side 415 of the top sash module may be provided with receiving means, such as a recess or groove 419 extending substantially in the total longitudinal extension of the top sash module 411 as shown on Fig. 3.

[0040] Preferably, the recess 419 is arranged such as to be flush with a corresponding recess or groove in the respective adjacent extensions 416 and 417 of the side sash members 11 and 12 in the mounted position of the top sash module 411, such as to enable providing the window 1 with a preferably circumferentially extending sealing 18 for sealing the gap between the sash 3 and the frame 2 in the closed position of the window 1.

[0041] The top sash module is normally intended to be provided in a length corresponding to the width of the window in question. It is also conceivable to provide the respective end parts of the top sash module as standard units for all window sizes in a range. The top sash module is then made to fit the particular window width in question by connecting an intermediate section of appropriate length with a standard unit end part at either end. In this manner, the need for stock-keeping of various sizes is reduced. The connection between the intermediate section and the standard unit end parts may be carried out in any suitable manner, for instance by moulding.

[0042] In alternative embodiments the top sash module 411 may alternatively be attached to the top frame member 5 or the sealing strips may be omitted.

[0043] Referring now to Figs 4 to 6 showing a slightly different embodiment, the window furthermore comprises at least one barrel bolt 420 described in further detail in the European patent EP2578764 having the same filing date as the present specification. Flere, an aperture intended for receiving a bolt of the barrel bolt 420 is shown at the bottom of the frame side member. This aperture is intended for receiving the barrel bolt in the cleaning position, i.e. when the sash has been turned past its normal opening angle. Another aperture is positioned near the top of the frame side member. If desirable, this aperture makes it possible to provide a further ventilating position at a relatively small angle, but still allows for more air entrance than by the ventilation flap 400 in itself.

[0044] It should be noted that the above description of preferred embodiments serves only as an example, and that a person skilled in the art will know that numerous variations are possible without deviating from the scope of the claims.
