Definitions

  • the present invention relates in a first aspect to a flat-roof skylight window for being positioned substantially horizontally in a flat roof, the skylight window comprising a window portion and a weather shield, which is mounted on the window portion to cover and weather protect the window portion in a mounted state of the skylight window.
  • the invention relates in a second aspect to a weather shield for use in the skylight window according to the first aspect of the invention.
  • a skylight window of a type which is used in inclining roofs and with a flat, insulating windowpane, is positioned in a flat roof, gravity will pull the pane downwards so that the pane will curve slightly downwards towards a centre thereof with a lowest point typically at a centre of the pane.
  • rain water will typically be collected at and near the lowest point to create, for example, a pool of water.
  • dirt will accumulate on the windowpane, especially at or near the centre thereof. This may limit the view through the windowpane from inside the building as the water and dirt disturb the visibility through the windowpane. Further, the pane may become a structural weak point, especially also with regards to snow loads.
  • One way to improve dewatering and prevent accumulation of snow on the windowpane is to angle the skylight window and the windowpane to provide a slope similar to a window positioned in an angled roof. This may be done by raising one side member of a frame and/or sash of the window so that the windowpane is angled with respect to horizontal. However, by angling the windowpane, one side member of the frame and/or sash will be higher than the opposing side, and the two side members at the sides will also slope. Hereby, the raised sash member and/or frame member as well as the sloping side members connected thereto may disturb the view through the windowpane compared to if the window were positioned horizontally.
  • raising one of the side members requires more sash and/or frame material, is cumbersome to construct and mount in the roof, and may create an undesired aesthetical appearance of the building since the windows will be more visible from the outside and look differently when they project upwards in a sloping manner from the flat roof.
  • PL 401880 discloses a flat roof skylight window with a windowpane and no weather shield.
  • a flat-roof skylight window positioned horizontally comprises a transparent weather shield, usually of a cast plastics material such as acrylic or polycarbonate and positioned above a window portion that comprises the frame and/or sash as well as the windowpane.
  • the weather shield typically covers an entire top surface and has a curved dome-shaped top surface so that collection of rain water, snow and the like on the top surface is lessened since it may run along sloped sides of the weather shield and onto the roof.
  • the weather shield typically covers the entire window portion and may generally protect the window portion and the interior of the building from a range of weather loads or influences, including wind and precipitation, such as rain, snow, hail, etc.
  • the weather shield may also provide supplementary insulation of the skylight window, i.e. of the window portion and the weather shield.
  • the weather shield is typically attached to a frame and/or a sash of the window portion.
  • weather shields may have several drawbacks.
  • shape of the weather shield due to its curvature or shape, distorts light and thus the view through the window and/or allows significantly less light to pass through the window.
  • Some prior art weather shields comprise a skirt, which extends on all sides of the weather shield to cover the sash and/or frame of the window portion, this skirt often getting in the way of opening the window by hitting parts of the window portion or the roof.
  • US 8,375,657 discloses an insulated glazing unit in which one of the glazing layers of a pane thereof is curved.
  • WO 08085072 A discloses a skylight window for sloped roofs and with a curved windowpane.
  • GB 1 203 154 discloses a weather shield according to the preamble of claim 6.
  • an object of the first aspect of the present invention to provide a flat-roof skylight window according to the introduction in which it is possible to reduce assembly of water and dirt on an upper or outer surface of the weather shield. Another object is to reduce distortion of the view through the skylight window. Another object is to provide a skylight window, which can be made openable. Another object is to balance a precipitation dispersing effect with wind load characteristics of a skylight window.
  • a flat-roof skylight window for being positioned substantially horizontally in a flat roof
  • the skylight window comprising a window portion with an optional window sash, a window frame and an insulating windowpane mounted in the window sash or window frame
  • a weather shield which is mounted on the window portion for covering and weather protecting the window portion in a mounted state of the skylight window
  • the weather shield comprises a weather shield pane, which is curved outwardly in relation to the window portion, the weather shield pane comprising two opposed substantially straight peripheral edges and two opposed curved peripheral edges, the weather shield pane further comprising a curved bottom surface facing the window portion and having four bottom corners positioned in an imaginary bottom plane P1, an apex line or peak line X extending between said two curved edges where the bottom surface of the weather shield pane has a largest distance to the bottom plane P1, a connecting line L1 connecting two of said bottom corners, the connecting line L1 extending substantially in parallel to
  • curved may be understood as having a non-linear shape, potentially without sudden or sequential steps.
  • the weather shield may be provided separately from the window portion.
  • the weather shield may be substantially symmetric about the apex line X.
  • Size and weight of a weather shield of the skylight window according to the invention may be made relatively small compared to the weather shields of the prior art, making it easier to open and saving on material. Also, due to the minimal extent that the weather shield pane projects upwardly in the mounted position of the skylight window, wind loads on the weather shield will be smaller and, thus, strength and stiffness requirements in relation to all parts of the skylight window as well as the roof in which it is potentially mounted will be reduced.
  • the weather shield pane will have a structural load capacity able to withstand larger loads both from wind and snow. Additionally, the weather shield pane can be relatively cheaply manufactured, even from stiffer and harder materials, such as glass or hardened glass, which may further increase the structural integrity of the skylight window and improve view through the window while achieving the above advantages.
  • the curvature of the weather shield pane may be so that in an entire area of a top surface of the weather shield pane, the top surface slopes upwardly, specifically in two top surface areas on both sides of the apex line, so that no depressions, and preferably also no horizontal areas, exist in or at the top surface.
  • the apex line itself may extend substantially horizontally in the mounted position of the skylight window.
  • the apex line may generally extend linearly.
  • the weather shield of the skylight window may further comprise a weather shield skirt supporting the weather shield pane and extending at one or more side edges of the weather shield pane to further seal the window portion from the surroundings and/or avoid or lessen entrance of water and/or dirt into the window portion.
  • One or more sealing elements may be located between the skirt and the weather shield pane.
  • the weather shield skirt may comprise four side skirt members, specifically two pairs of opposed side skirt members, and these four side skirt members may be positioned to substantially form a rectangle.
  • the side skirt members may each be substantially plane and/or extend substantially linearly and/or may take the form of profiled skirt members, potentially comprising or consisting of aluminium.
  • the weather shield skirt may be attached to the window portion, specifically to the window frame or the window sash of the window portion so as to place the weather shield pane in position above the window portion.
  • the plane P1 may be substantially parallel to a plane of the window portion windowpane.
  • the skirt members may extend substantially at respective right angles to the plane P1.
  • One or more of the side skirt members may support a respective peripheral edge, i.e. a side edge, of the weather shield pane.
  • the weather shield pane may thus comprise four corresponding side edges.
  • the weather shield pane may be embedded or mounted in and/or attached to the weather shield skirt.
  • a cushioning member and/or an adhesive, such as glue, or an adhesive member, such as an adhesive tape, may be provided between edges of the weather shield pane and supporting surfaces of the weather shield skirt. Additionally or alternatively, the weather shield pane may be attached to the weather shield skirt by clamping or other mechanical means.
  • the weather shield side skirt members may each be an aluminium profile.
  • the weather shield pane may be positioned with its two straight peripheral edges substantially parallel with two opposed side skirt members and with its two curved peripheral edges extending along or adjacent to other two opposed side skirt members.
  • the weather shield pane preferably has a substantially constant thickness along an entire pane area, a distance between a top surface and the bottom surface of the weather shield pane potentially being substantially constant over an entire area of the weather shield pane. This further prevents distortion of the view through the skylight window.
  • This thickness may be 3 mm to 7 mm, preferably 4 mm to 6 mm.
  • An entire upper or lower surface area of the weather shield pane may be 0.5 m 2 to 10 m 2 , preferably 0.7 to 6 m 2 , more preferred 0.8 to 4 m 2 .
  • the shape of the weather shield pane in a cross-sectional plane can be concave, parabolic, cylindrical or elliptic cylindrical.
  • the curved edges of the weather shield pane may substantially follow an arc, e.g. an elliptic or circular arc, and the pane may follow an arc, e.g. an elliptic or circular arc, in a cross section taken along a cross-sectional plane extending substantially at a right angle to a plane through which the apex line X extends and at a right angle to the plane P1.
  • the weather shield pane may comprise only one single layer of glazing.
  • the insulating windowpane of the window portion may comprise at least two layers, for example two or three layers, of glazing mounted in the window sash or the window frame, potentially with an inert gas between them.
  • the window frame and or the window sash may have four side members that may be positioned substantially rectangularly.
  • a glazing of the window portion including the windowpane may take the form of a so-called IGU (Insulating Glazing Unit).
  • the skylight window according to the invention may be openable. This may be achieved with a window portion that in itself is openable, whereby the window sash may open in relation to the window frame.
  • the weather shield may be attached to the window sash of the window portion so that the window sash and the weather shield move and/or rotate together to open in relation to the window frame. This may be achieved by the window sash rotating along one of the window frame side members during opening of the skylight window, one side sash member being rotatably attached to the window frame along the said window frame side member.
  • the weather shield may be mounted on the window portion in such a manner that the weather shield follows the window sash in an opening movement by the window sash in relation to the window frame.
  • a chain drive system may be provided to achieve the opening and closing movements.
  • the weather shield according to the second aspect of the present invention makes it possible to design the skylight window so that it can be opened more easily in the described manner, see further below.
  • the weather shield pane is preferably a windowpane and/or preferably is transparent and/or translucent, i.e. allows light to pass through it. Preferably, at least 50, 60, 70, 80 or 90 percent of visible light is allowed to pass through the weather shield pane.
  • the angle ⁇ between the bottom plane P1 and the inclination plane P2 is preferably between 1 and 8 degrees, more preferred 1 and 6 degrees, more preferred 2 and 6 degrees, more preferred 2 and 5 degrees, more preferred 2 and 4 degrees, more preferred between 2.5 and 3.5 degrees, most preferred about 3 degrees.
  • the apex line may have a distance to the plane P1 of 5 to 100 mm, preferably 10 to 80 mm, more preferred 15 to 40 mm. Additionally or alternatively, the apex line may follow a centre line, which may be linear, of the weather shield pane. Additionally or alternatively, the apex line may extend in parallel with one or both of the straight edges of the weather shield pane. Additionally or alternatively, the apex line may extend at a length substantially identical to a length of one or both of the straight edges of the weather shield pane.
  • the weather shield pane, the window sash and/or the window frame may have an overall rectangular or quadratic shape.
  • the skylight window according to the invention may be mounted in a flat roof so that the plane P1 is substantially horizontal and or the windowpane of the window portion is substantially horizontal.
  • the angle of the plane P1 and/or of the windowpane of the window portion to horizontal in the mounted state may be 0 to 5 degrees, 0 to 4 degrees, 0 to 3 degrees, 0 to 2 degrees or 0 to 1 degrees.

  • Attachment of a weather shield skirt to the weather shield sash may be accomplished in a similar manner.
  • the weather shield pane is shaped substantially as a cylinder shell segment curving outwardly in relation to the window portion.
  • the cylinder shell segment may be a circular cylinder shell segment so that the curved peripheral edges of the weather shield pane substantially follow a circular arc.
  • a radius of the circular cylinder shell segment may be 2.5 to 15 m, 5 to 12 m, 7 to 10 m or 7.5 or 8.5 m.
  • the cylinder shell segment need not necessarily be of a circular cylinder, but may be of other cylinder shapes. It is preferred that the cylinder shell segment curves outwardly along an entire curve of the cylinder shell segment so that precipitation is not collected in pockets of the surface of the weather shield pane, see also above.
  • the structural benefits of cylinder shell shaped structures are made use of in the weather shield pane, e.g. the moment of inertia of the weather shield pane is increased, thus improving strength and stiffness of the flat-roof skylight window.
  • the curvature of the weather shield pane is substantially parabolic. In any case, it is preferred that the curvature of the weather shield pane does not comprise any sequential steps, i.e. immediate or sudden changes of curvature that may disturb the view through it.
  • a substantially parabolic weather shield pane is provided.
  • manufacturing of the weather shield pane may be simplified as a flat pane that can simply be fixed at two opposed straight side edges and a force applied at the centre, whereby the pane will curve outwardly. This is especially a structural possibility due to the relatively low angle ⁇ . Thus, manufacturing costs can be reduced.
  • the weather shield pane is made of or comprises glass, preferably hardened glass.
  • a weather shield glass pane may be moulded or cast to assume its final, curved shape or it may be cast first, e.g. in a substantially plane shape, and then subsequently deformed to assume its curved shape.
  • the weather shield becomes more wear resistant, as glass is less prone to scratching, denting and the like, and because glass has typically better structural characteristics, such as strength, hardness and stiffness. Scratches and dents will increase the roughness of the weather shield pane surface so that water will more likely be retained on the surface of the weather shield if the weather shield pane is made of plastic. Comparably, especially the dome-shaped plastic weather shields of the prior art would be expensive to manufacture in glass.
