    专利说明:

    The present invention relates to a window system adapted for being mounted in an inclined surface of a building, said window system comprising a frame structure including a plurality of frame members and a sash structure including a plurality of sash members, where the frame structure and the sash structure each defines a substantially rectangular unit with an inner opening, a lower surface intended to face downwards in the mounted state of the window system, an upper surface intended to face upwards in the mounted state of the window system, and two side surfaces extending between the lower and upper surfaces, and where said surfaces of the frame structure meet at four corners of the window system, a pane element supported by the sash structure and including at least two sheet elements, such as sheets of glass, separated by one or more spacer members, an interior sheet element forming an interior side of the pane element intended to face the interior of the building in the mounted st ate of the window system and an exterior sheet element forming an exterior side of the panel element intended to face the exterior in the mounted state, each of the interior and the exterior sheet elements having a lower edge intended to face downwards in the mounted state of the window system, an upper edge intended to face upwards in the mounted state of the window system, two side edges extending between the lower and upper edges, and at least one operator arranged on an outer side of the frame structure opposite the inner opening and at the lower surface thereof.
    The invention further relates to a method of water proofing such a window system.
    Such a window system where, for example, an engine operator is arranged on the outer side of the sash and frame structures to be concealed for the user of the window is described for example in EP2472043A1. This window works very well, but it has been discovered that, especially when mounted with a very low inclination, it is difficult to provide satisfactory water proofing of the transition between the pane element and the sash structure. Furthermore, the system of covering and flashing members used to protect the motor and similar devices arranged on the outer side of the frame structure is also relatively complex.
    It is therefore the object of the invention to provide a window system with an alternative covering of an operator arranged on the lower outer side of the window.
    This is achieved with a window system containing at least one sheet element of the pane element projects over the lower surfaces of the sash structure and the frame structure away from the inner opening, and which further includes a frame extension element and at least one covering or sealing element, where the frame extension eiement is attached to a frame bottom member and projects with a distal edge towards the lower edge of at least one sheet element of the pane eiement, and where the at least one covering or sealing element closes a gap between the distal edge of the frame extension eiement and the pane element, said covering or sealing element extending substantially in parallel with the frame bottom member.
    The projecting sheet or sheets of the pane element covers not only the transition between the pane eiement and the sash structure, but also the space between the sash and frame structures and, depending on the length of the projection, potentially also the entire exterior side of the the operator and similar devices arranged below the frame structure in the mounted state. Accordingly, water, snow and ice on the pane will be led over these critical places in the construction on an uninterrupted pane surface and from there either directly onto a surface of the building, which is resistant to water, e.g. a roofing, or onto a covering member or flashing member.
    The frame extension element and the at least one covering or sealing element covers the gap between the lowermost edge of the pane eiement and the building, covering or flashing to prevent water, snow, dirt etc. from being forced upwards into the window structure below the influence of wind. The frame extension element substantially spans the gap from the frame bottom member to the pane element, but cannot be connected thereto as it would then not be possible to open the window. The covering or sealing element provides an overlap or sealing engagement between the frame extension member and the pane eiement, thereby providing a water tight construction. To provide a good water tightness, the window may include both a bottom covering element attached to the sash structure or the pane element and a sealing element attached to the frame extension element, and a still more efficient water proofing can be achieved if the sealing element is in contact both with a sheet element of the pane element and with the bottom covering element in the dosed state of the window.
    The bottom covering element, either used alone or in combination with a sealing element, is preferably attached to the pane element. If attached to the inner side of a sheet element, the attachment will be protected from the weather, which may be particularly advantageous when using glue or an adhesive. Attaching the bottom covering element to the exterior side of the exterior sheet element, however, may provide a good transition between it and other covering elements used on the sides of the window. However, it is also possible to attach the bottom covering element to other covering elements or to provide one unitary covering element covering both the sides and the bottom of the window.
    In one embodiment, the bottom covering member includes a first bottom covering member attached to the exterior sheet element and extending substantially in parallel, and a second bottom covering member attached to the first bottom covering member and extending substantially perpendicularly the exterior sheet element toward the plane defined by the interior side of the pane element. Apart from allowing each of these members to be structurally simple and hence cheap to manufacture, this also allows easy adaptation of the window for different installation situations, such as differences in inclination and installation depth. As an example, if the inclination is relatively low, the distance between the lower edges of the pane element and the surface of the building will often be relatively large and a large second bottom covering member may then be used. Likewise, if the window is mounted relatively deep in the building surface, the distance between the lower edges of the pane element and the surface of the building will usually be small and a second bottom covering member of limited size then used. It may even be possible to leave the second bottom covering member out in some installation situations if the first bottom covering member is formed appropriately.
    To achieve the desired coverage of the operator without making the total construction very bulky it may be advantageous to use a so-called stepped pane element, where the exterior sheet element extends further away from the sash and frame bottom members than the interior sheet element. In such cases, the cross-sectional shape of the frame extension element may include a first leg extending substantially perpendicularly to the plane of the pane element and forming the distal edge, and a second leg extending substantially in parallel to the pane element between the first leg and the frame bottom member. In this way, the frame extension element may follow the shape of the interior side of the stepped pane element, so that the distal edge of the frame extension element reaches up to the interior side of the exterior sheet element.
    The cross-sectional shape of the frame extension element may further include a third leg extending substantially perpendicularly to the plane of the pane element, giving the frame extension element the overall shape of a Z, where said third leg is used for attachment to the frame bottom member. This provides a simple and reliable element with a relatively high strength and bending stiffness.
    Depending on the design of the window, an angled or Z-shaped frame extension element may also be used in combination with a none-stepped pane element.
    The frame extension element may include a bend and / or groove at the distal edge used for attachment of a sealing element and / or for interconnection with a flashing member or other members of the window as will be explained in detail below.
    To ensure proper water proofing of the window it is preferred that the frame extension element and the at least one covering or sealing element extend from one side edge of the panel to the other, but it is of course also possible to use two or more separate members covering the total width of the window. Likewise, it is to be understood that one or more elements may have to be wholly or partially interrupted to make room for other members of the window. One example is that the frame extension element may be provided with an opening through which a member of the operator, such as a motor chain, projects.
    The object of the invention is further met with a method where the pane element is arranged so that at least one sheet element of the pane element projects over the sash structure and the frame structure away from the inner opening at the bottom of the window, where a frame extension element is attached to a frame bottom member so that it projects with a distal edge towards the pane element, and where at least one covering or sealing element is arranged so that there is a gap between the distal edge of the frame extension element and the pane element and extends substantially in parallel with the frame bottom member.
    In the following the invention will be described in more detail with reference to the drawing where
    FIG. 1 is a perspective view showing three windows installed as a group with one common covering and flashing assembly,
    FIG. 2 shows one of the windows in Fig. 1 with associated flashing members,
    FIG. 3 is a cross-sectional view along the line Ill-Ill in FIG. 2
    FIG. 4 is a cross-sectional view along line IV-IV in FIG. 1, but where side members of the sash and frame and side cover members have been removed, and
    FIG. 5 is a perspective view of a frame extension element. A series of three window systems according to the invention, in the following also referred to as windows only, are shown in FIG. 1 and the center window system is shown from a slightly different angle in FIG. 2. Each window comprises a panel element 1 supported by a sash structure 2, which is connected to a frame 3. A covering and flashing assembly 4 includes a plurality of flashing members 41-46 used for bridging the gap between the windows and the building. surface (not shown) in which they are mounted, and a plurality of covering members 51-54 used to cover exterior surfaces of the win dows. Mounting brackets 6 are provided at each corner of the window, only two being visible in FIG. 2nd
    In the embodiment shown the flashing members 41-46 and the mounting brackets 6 are adapted for installation of the windows on a so-called upstand (not shown), which is a load-bearing frame construction typically formed on a roof with limited inclination as described for example in EP2472027. However, it is to be understood that the present invention works equally well in other installation situations where the flashing assembly and mounting brackets are of a different configuration.
    Turning now to Figs 3, which shows a sectional view of the bottom parts of the center window of Figs. 1, the operator 7 is seen on the outer side of the frame bottom member 31 at the lower edge of the pane element 1. The operator includes an operator housing 71, a motor 72 and a chain 73. The chain transmits forces from the motor to a yoke 25, which is part of the sash structure 2.
    When mounting windows in groups as in Fig. 1 It is common to make some of the windows as passive units without hinges and operators to reduce both the initial cost and cost of maintenance and repairs. In a group of three windows as in Fig. 1, the center window will typically be an active window with operator, whereas the left and right windows will be passive, but other configurations are of course possible. In such cases, the space occupied by the operator housing 71 in active windows may be filled with an insulating member in the passive windows. Accordingly, the outlines of the operator housing in Figs. 4 may also be seen as representing such an insulating member.
    In Figs. 3 and 4, the pane element 1 includes two sheet elements 11,12 separated by a spacer 13. The inferior sheet element 11, which for safety reasons consist of laminated glass, only projects over the lower surfaces of the sash bottom member 21 and the frame bottom member 31, while the exterior sheet element 12 projects somewhat further and covers the operator 7. A pane element of this type is known as a stepped pane.
    The lower edge of the interior sheet element 11 abuts a glass holder 14 arranged on the yoke 25. When the window is mounted with a steep inclusion the provision of the glass holder 14 allows the yoke to carry at least some of the weight of the yoke. pane element, thereby minimizing the forces on the actual sash members.
    It is to be understood that the invention also applies to windows, where only one sheet element of a stepped pane element 1 projects over the sash 2 and frame 3, and to windows with a traditional non-stepped pane element. In the first case the interior sheet element 11 may then be arranged to abut the sash bottom member 21 as described for example in DE10059849A1, and in the laughing case the yoke will be on the interior side of the interior sheet element. The use of a traditional none-stepped pane element has the advantage that this type of pane is cheaper than a stepped pane, but as will be apparent from Figs. 4 There will then be less room for the operator, or alternatively the sash will have to be higher to make room for the yoke, thus making the window construction more bulky. A bottom sash covering two covering members 51,52 is provided at the lower edge of the exterior sheet element 12, which forms the lowermost edge of the window as such.
    One covering member 51 has the shape of an L and is attached with its longer leg 511 to the exterior surface of the exterior sheet element 12 by means of an adhesive. If it is of a very flat design, water on the exterior pane surface will run substantially without meeting any resistance. The shorter leg 512 of the L envelopes the lower edge of the exterior sheet element 12, projecting downwards towards a flashing member 41, which is embodied substantially as described in EP2472027 and which will therefore not be described in further detail here. If designed appropriately, this first covering member 51 might in principle be sufficient, but in the embodiment shown, a second covering member 52 is attached to its shorter leg.
    The second covering member 52 is here attached to the first covering member 51 by a snap-locking engagement with a pair of barbed legs 513, 514 thereon, but it will be understood that other means of attachment, including adhesives and even welding, are also possible. A two-part covering with a releasable interconnection is presently preferred, since it allows removal of the second covering member 52 for maintenance of the connection between the operator chain 73 and yoke 25.
    The second covering member 52 shown in Figs 3 and 4 has two legs 521, 522 projecting towards the flashing member 41, the first leg 521 forming the lowermost outer surface of the window structure. The second inner leg 522 has the shape of an inverted Y, meaning that a total of three leg end edges are located a short distance above the outer surface of the bottom flashing member 41. This provides a very effective maze sealing where the formation of air whirls will prevent water, snow and dirt from being forced underneath the covering under the influence of wind.
    Although described here in combination, it is understood that the features of the first and second covering members 51, 52 are independent of each other except for the male and female parts providing the interconnection between the two. Accordingly, the legs 521,522 of the second covering member may, for example, be found even when the first covering member is embodied in a different way and when making the window with only the first covering member, similar may be provided thereon.
    Also contributing to the maze seal is a frame extension element 35, which projects from the frame bottom member 31, over the operator housing 71 and almost up to the lower edge of the exterior sheet element 12 of the pane element. Wind blowing against the window from the left in Figs 3 and 4 will thus not only have to pass the whirl chambers formed between the flashing member 41 and the legs 521, 522 of the second covering member 52. If will also have to come up between the second leg 522 of the second covering member and a first leg 351 of the frame extension member 35, which extends substantially perpendicularly to the plane of the pane element, and turns at the distal end edge thereof in order to enter the window structure.
    Here the flashing member 41 has an upstanding leg 411, the end of which is held in a bend at the distal end of a first leg 351 of the frame extension element, thus providing a very reliable and water tight connection, but this need not be the case. Flashing connectors 45, which are seen most dearly in FIG. 1, are also provided with a leg 451 held in the bend in a similar manner as shown in FIG. 4. If the readily apparent to the skilled person, the flashing members and / or flashing connectors may be embodied without the upright legs 411,451, for example projecting a short distance below the frame extension element or with shorter legs not reaching up to the bend , without necessitating adaptation of other parts of the window.
    As shown in more detail in FIG. 5, the frame extension element 25 here has the overall shape of a Z with a second leg 352 extending over the operator housing 71 substantially parallel to the pane element 1 and a third leg 353 being used for attachment to the outer surface 311 of the frame bottom member 31. The third century is provided here with two longitudinal projections 354 and a series of openings 355, which allows it to be attached to the frame bottom member by means of screws, rivets or the like, but it will be understood that other means of attachment are possible. It is also understood that the third leg may be left out completely and that the second leg may then be attached to the exterior surface 312 of the frame bottom member or even to the operator housing 71 if designed appropriately.
    As will also be seen from Figs 3 and 5 the second leg 352 of the frame extension member 35 is provided here with an opening 358 through which the operator chain 73 may pass, but it is also possible to simply interrupt the second leg or even the entire frame extension member at this place. In passive windows the frame extension element may be continuous without openings or interruptions.
    At the distal end of the first leg 351 of the frame extension element is split into two so that the two end edges 357,358 form a longitudinal groove. This groove is adapted for receiving a projection 551 on a sealing element 55 as shown in Figs 3 and 4.
    The sealing element 55, which is shown in its uncompressed state, further improves the tightness of the construction by sealing the small gap left between the frame extension member 35 and the covering members 51,52 and / or the pane element 1. In this embodiment a head 552 of the sealing element is in engagement with the interior side of the exterior sheet element 12 in the dosed state of the window and a tail 553 of the sealing element is adapted for engagement with the second covering member 52. The tail 553 of the sealing element is bent back from the second covering element 52 to prevent it from sticking to the covering and being torn when the window is opened and dosed repeatedly. It is also possible to make the tail part 553 with a circular cross-section instead of the section of a circle forming the tail in Figs 3 and 4.
    The head of the sealing element is here embodied with a longitudinal hollow allowing compression and a lip adapted for a very tight sealing engagement with the panel, but it is understood that other embodiments are possible and that the shape of the head is independent of the shape of the tail. For example, head adjustment may be needed if a first covering member is attached to the interior side of the exterior sheet element.
    Likewise, it will be understood that the frame extension element may be embodied without the groove at the distal end and that the sealing element will then have to be adapted for being attached in another way. As an example, it may be provided with a groove fitting over the distal edge of the frame extension element or be attached by means of an adhesive. It is also possible to provide the sealing as a co-extruded part of an extruded frame extension member.
    The design of the sealing element 55 shown in Figs 3 and 4 and described above is adapted for use in a window structure with a covering, but it will be understood that the combination of the frame extension element 35 and a sealing element alone could lead to a satisfactory water proofing of the window. In that case, the tail 553 of the sealing element could be dispensed with and the groove formed by the two ends 357,358 of the first leg 351 of the frame extension element could advantageously face upwards towards the interior side of the exterior sheet element 12. It would also be advantageous to make the exterior sheet element 12 of the pane element 1 project even further in order to reduce the weather exposure of the sealing element.
    In the above the different element used for water proofing the window has been described primarily with reference to the cross sections in Figs 3 and 4, but it is understood that the covering and sealing elements ex tending substantially in parallel with the frame bottom member over substantially the entire length thereof. Likewise, it is to be understood that separate end closure elements may be provided at the corners of the window, but that the overlap of the side covering members 54 shown in Fig 1 will often suffice when windows are arranged side-by-side and that end flashing members 43.44 provide closure at the ends of a group of windows.
