Definitions

  • the present invention relates to a roof window system comprising at least two window units configured to be built in side by side, separated by a spacing, in a roof structure of a roof, in particular comprising an inclined roof surface, each window unit defining a width and a common height, said roof window system defining a combined width in a mounted condition and comprising an insulating assembly including a plurality of frame members forming at least one insulating frame, the insulating assembly comprising two side members, each side member having a length corresponding substantially to the common height of the window units, a plurality of top and bottom members including at least a first and a second top member, and at least a first and a second bottom member, and two transition members, each transition member being configured to be positioned between facing ends of the at least first and second top members, and the at least first and second bottom members, respectively, the two side members, the plurality of top and bottom members, and the two transition members forming a single insulating frame extending along a periphery of the window units including the
  • Roof windows to be installed in inclined roof surfaces come in a variety of types, and are either installed as stand-alone window units, in which all sides of the roof window borders on the roofing, or in configurations in which several window units are built together to combine into larger arrays providing a larger light influx into a room of a building, and in which only outer sides of the window units border on the surrounding roofing.
  • the window units are typically standard roof windows in which the right side frame member of the left-hand window unit is located adjacent to the left side frame member of the right-hand window unit, and/or the bottom frame member of the upper window unit is located adjacent to the top frame member of the lower window unit.
  • a roof structure comprising rafters and battens
  • at least one rafter and a number of battens will typically need to be removed to provide a sufficiently large aperture in the roof surface and roof structure. Removing battens weakens the roof structure, additionally the insulation of the roof itself is reduced when an opening is created in a roof structure.
  • each transition member comprises an insulating element and an engagement element configured to bring the transition member into engagement with the associated top and bottom members at the respective facing ends thereof, that each member of said plurality of top and bottom members has a length corresponding substantially to the respective width of the window units, that each transition member has a shape adapted to the shape of the respective member of said plurality of top and bottom members, and that the single insulating frame spans the combined width and the common height of the roof window system in the mounted condition.
  • the single insulating frame is easily assembled, since the transition members fit the respective ends of the top and bottom members, and furthermore, the engagement element of each transition member facilitates the connection of the transition members to the adjacent top members and bottom members, respectively.

  • standard insulating frame piece encompasses components of commercially available insulating frames fitting a counterpart roof window of a pre-defined size, for instance within a size range of products. In this way, cost-effective manufacture and storage are obtained, since the only part that needs to be tailored is the transition member.

  • the roof window system 1 comprises two window units 11, 12 configured side-by-side.
  • a window unit can consist of a single window including frame, sash and pane etc. and/or comprise of more than one single window. It could be two windows placed over and under each other as seen in an inclination of the roof or positioned arbitrarily in extension of each other in the roof surface, and preferably having a common width and thus individual height. Each such window in an over and under configuration could also have unique features relating to the frame, sash and pane etc. It could be a fixed frame with a pane, a frame with a sash being fixed or able to turn around a centre, top, bottom or side axis. Alternatively or additionally, the frame could hold a ventilation device, solar panel etc. Also such a window unit could be of different size, e.g. width, compared with another unit to be placed in the side by side configuration.

Typically, some standard distances are foreseen, but in principle, the cover assembly could be provided for spacings ranging from a contact within the neighbouring roof windows to 500 mm within the neighbouring roof windows. In the embodiment shown, a standardized width of the gap G of the spacing SP of 100 mm is described. The person skilled in the art would be aware of necessary adaptions to the cover assembly to accommodate other dimensions.
  • the cover assembly comprises a set of receiver brackets 7 configured to be connected to the facing side members 113, 122 of neighbouring window units 11, 12 and a cover plate 8 configured to be brought into releasable engagement with the set of receiver brackets 7.
  • a prior art cover arrangement of a commercially available product traded under the name VELUX ® Dormer is shown in Fig. 28a and Fig. 28b .
  • the set of receiver brackets 7 here includes four items. The number may be chosen in dependence of the height of the window units and hence of the roof window system; however, four receiver brackets have been found appropriate for most sizes window units.
  • each receiver bracket 7 is adapted to be installed in a groove 17 in adjacent frame members 113, 122 of neighbouring window units 11, 12.
  • This groove 17 is as mentioned in the above circumferential and typically provided in the frame of most roof windows.
  • the groove 17 of the adjacent frame members serves to receive the receiver brackets 7.
  • Each receiver bracket 7 comprises a base portion 70 from which a set of two second mounting elements 71 protrude to form rounded shapes, a second engagement portion 72 being here formed near an end of the respective second mounting element 71.
  • each receiver bracket 7 comprises a leg 73 at an end of the second engagement portion 72 opposite the base portion 70.
  • each leg 73 is received in the groove 17 of the respective frame member 113, 122.
  • one or more holes 74 are provided in each leg 73 as shown in Fig. 30 in which two holes 74 are provided and configured to receive fastening means such as screws (not shown).
  • the cover plate 8 comprises a base portion 80 from which a set of two first mounting elements 81 protrude, a first engagement portion 82 being preferably formed near a free end of the respective first mounting element 81.
  • the cover plate 8 comprises an additional leg 83, preferably provided with a hook 84. Referring to Fig. 27 showing the engaged position, it is seen that the hook 84 is placed close to the frame members such that the entry to the groove 17 is also covered. It is furthermore seen that a side edge 801 of the base portion is located beyond the position of the respective first mounting element 81. In this way, the cover element 8 overlaps not only the entire spacing SP but also the portion of the side members 113, 122 in which the groove 17 is located.
  • the circumferential groove 17 also receives the vapour barrier collar 97.
  • the exact configuration of the vapour barrier collar 97 could in principle be chosen in any suitable way but it is preferred that that not only the top, bottom and outermost side members of the window units are provided with portions of the vapour barrier collar 97, but also the spacing SP between facing side members of the two neighbouring window units 11 and 12 as indicated in Fig. 26 .
  • the vapour barrier collar 97 is here formed as a strip spanning the spacing SP between the neighbouring window units 11 and 12.
  • a gasket 971 is included in the vapour barrier collar 97.
  • the legs 73 of the receiver bracket 7 are thus positioned such that the gasket 971 is squeezed between the leg 73 and the bottom of the groove 17.
  • the cover plate 8 comprises a first mounting element 81 and the receiver bracket 7 comprises a complementary second mounting element 71, and the first mounting element and the second mounting element are adapted to be brought into contact with one another.
  • the first mounting element 81 and the second mounting element 71 comprises such complementary shapes that movement of the cover plate 8 relative to the receiver bracket or receiver brackets 7 in a mounting direction is possible while movement in the opposite direction is at least temporarily prevented by a first engagement portion 82 on the first mounting element 81 brought into engagement with a second engagement portion 72 on the second mounting element 71 to ensure a snap or clip engagement.
  • the first mounting element 81 and the second mounting element 71 could be provided at one longitudinal edge of the cover plate 8 and the receiver bracket 7, respectively; however, it is preferred that they as shown are symmetrically placed along both side edges.
  • the first and second engagement portions 82, 72 are formed as mutually cooperating shapes including a protrusion, an indent, a wave shaped, a barb, a hook-shaped element, a catch-shaped element, a T-shaped cross-section, a V-shaped cross section and an arrowshaped cross section or any combination thereof.
  • the dimensions of the various parts are typically chosen in accordance with the material chosen.
  • the first mounting element 81 forms an angle ⁇ with a direction perpendicular to the base portion 80 of the cover plate 8. The angle ⁇ is small, typically about 2 to 5°, and ascertains that safe guidance of the cover plate 8 over the receiver brackets 7 is ensured.
  • the first mounting elements 81 may be said to have the form of a track configured to be guided over and to be received, partially or fully, by the second mounting elements 71.
  • the cover plate 8 is placed such that the first mounting elements 81 with the respective first engagement portions 82 are guided over the second mounting elements 71 of the receiver brackets 7, until the first engagement portions 82 snap behind the second engagement portions 72.
  • the legs 73 also function as a stop of the movement such that the installer will experience a clear indication, for instance in the form of a distinct sound, that the mounted condition has been reached.
  • Each receiver bracket 7 is made of a robust material such as metal or an alloy or a plastic compound or a combination thereof, preferably extruded.
  • the cover plate 8 is typically made of a metal or an alloy or a plastic compound or wood a combination thereof.
  • a demount tool 85 is provided in an embodiment of the roof window system according to the invention.
  • the demount tool 85 comprises a substantially plane base 850. From the base 850, a first flange 851 protrudes at a rounded section 852, ending in an edge 8511.
  • a second flange 853 protrudes from the base 850 at a distance from the first flange 851. The second flange 853 ends in an edge 8531 slightly beyond the edge 8511 of the first flange 851.
  • a grip opening 854 is provided in the base 850.
  • the first flange 851 of the demount tool 85 is introduced into the gap behind the leg 83 of the cover plate 8, at the position of the hook 84.
  • the second flange 853 of the demount tool 85 overlaps the base portion 80 of the cover plate in the area of the side edge 801 while the base 850 of the demount tool 85 is substantially perpendicular to the plane of the base portion 80.
  • the user then rotates the demount tool 85 outwards, i.e. in the direction away from the base portion 80 of the cover plate 8, by way of a lever rotating about the rounded section 852 which in turn abuts a surface of the side member 113, 122 in question.
  • the applied moment releases the engagement between the cover plate 8 and the receiver bracket 7. If needed, the process is repeated at the position of each receiver bracket 7 and at both side edges 801 of the cover plate 8.
  • the demount tool 86 comprises a base 860. From the base 860, a flange 861 protrudes while a handle portion 864 is formed oppositely to the flange 861. In case the cover plate 8 is to be removed, the flange 861 of the demount tool 86 is introduced into the gap behind the cover plate 8 and the engagement between the cover plate 8 and the receiver bracket 7 is released by handling the demount tool 86.
  • An opening 865 is provided in the handle portion 864 in order to allow hanging the demount tool 86 on for instance a hook in-between uses.
  • reinforcement ribs 866 are provided to incur rigidity to the demount tool 86.
