Definitions

  • the invention relates to a screening arrangement according to the preamble of claim 1.
  • the invention furthermore relates to roof window comprising such a screening arrangement.
  • Screening arrangements must fulfil different requirements depending on whether they are installed in a façade window, i.e. in a substantially vertical position, or in an inclined or even horizontal surface such as a roof.
  • connection between the top casing and the side rail is near seamless it is still vulnerable to dust and other contaminants entering the screening arrangement at the connection.
  • This also applies to the configuration of covering elements in other prior art documents.
  • the dust and other contaminants may have adverse effects such as increasing friction of movable parts or negatively interacting electrical components.
  • manufacturing of the complementary shapes can be expensive and cumbersome.
  • each first and second corner cover element has such dimensions that an overlap is provided between the corner cover element and the underlying top casing and side rail in the mounted condition of the screening arrangement, and that the bottom surface of each first and second corner cover element is configured to absorb incident light on the bottom surface, by providing the bottom surface as a surface of dark colour, such as black.
  • the corner cover assembly manufacturing the side rails and the top casing may be eased.
  • the side rails do not need to be manufactured with a shape complementary to that of the top casing and vice versa for the top casing.
  • the top casing and the side rails need not create a near seamless connection.
  • the ends of the side rails may be tapered or mitred with a complementary shape to that of the top casing to avoid any openings in-between the side rails and the top casing.
  • the taper of the side rails in many cases requires an additional manufacturing step.
  • this additional manufacturing step may be obviated.
  • the overlap between the corner cover elements and the underlying top casing and respective side rail ensures adequate light-proofing, since for instance manufacturing tolerances may easily be accommodated.
  • the bottom surface may also absorb light passing in-between the corner cover element, the side rail and/or the top casing.
  • the side rail and/or the top casing will attempt to reflect off the bottom surface when trying to pass in-between the corner cover element, the side rail and/or the top casing.
  • having the bottom surface absorbing incident light will stop light from reflecting off the bottom surface.
  • the bottom surface may absorb light attempting to pass through the screening arrangement from the interior towards the exterior.
  • the bottom surface may absorb light attempting to pass through the screening arrangement from the exterior towards the interior.
  • the bottom surface may be provided by forming the bottom surface from a dark element, and/or by applying a dark coating to the bottom surface.
  • an “interior” may be the interior of a building on which the roof window to be screened by the screening arrangement is installed.
  • the interior may for instance refer to a room in which the roof window with the screening arrangement is installed.
  • an “exterior” may be the outside of the building on which the roof window to be screened by the screening arrangement is installed.
  • the bottom surface In the mounted condition of the screening arrangement, the bottom surface typically faces in a first direction towards the interior and the top surface faces in a second direction towards the exterior, wherein the first direction is opposite the second direction.
  • each corner cover element is connected to the top casing and the adjacent side rail, after these elements have been assembled and are ready for mounting in the assembled state in the roof window. This is made possible in that the connection takes place in a direction perpendicular to the plane containing the exterior surfaces of the top casing and the side rails.
  • each first and second corner cover element has a shape adapted to the contours of the top casing and the side rails. This provides for an improved light-proofing since abutment between the corner cover elements and the top casing and side rails is ensured.
  • each first and second corner cover element comprises at least two outer sections, each having a shape of an inverted U-shape, configured to be positioned at or near the outer perimeter of the screening device to accommodate an outer section of the top casing and the adjacent side rail and/or a structure positioned outside the outer perimeter of the screening device.
  • the screening arrangement comprises a suspension device comprising a plurality of flanges connected to or connectable to the top casing and the side rails.
  • the flanges are displaced to the exterior relative to an exterior side of the top casing and the side rails, since the two outer sections of inverted U-shape of the first and second corner cover element may then interact with the flanges.
  • the top surface is configured to reflect incident light on the top surface, preferably by providing the top surface as a surface of light colour, such as white. Having the top surface reflecting incident light lowers heating of the screening arrangement. Heating of the screening arrangement may wear away components, especially plastic components, thus by lowering heating the lifetime of the screening arrangement is prolonged.
  • the top surface may be provided by forming the top surface from a bright element, and/or by applying a bright coating to the top surface.
  • each corner cover element comprises engagement means adapted for engagement with the top casing, preferably via a snap-fit connection, more preferably by the top casing being provided with openings for receiving legs of the first and/or the second corner cover element in a snap-fit connection.
  • first and/or the second corner cover element comprises a protrusion for covering a connection between the roof window and the screening assembly. Consequently, the corner cover assembly protects the connection between the roof window and the screening assembly.
  • the first and/or the second corner cover element comprises an electric grove extending in parallel with the top casing for accommodating one or more electric components extending from the top casing. This is particularly advantageous in screening arrangements powered by a solar panel, since the cable from the solar panel to a motor unit of drive means located within the top casing may then be accommodated in the electric groove.
  • first and the second corner cover element may each comprise a cover flange extending from a perimeter of the first and the second corner cover element to minimize a clearance between the first and the second corner cover element and the two side rails and the top casing.
  • the cover assembly comprising a third and a fourth corner cover element each covering an end of the two side rails opposite the top casing. Consequently, both ends of the side rails are protected from and other contaminants entering the side rails.
  • corner cover assembly has been described comprising two corner cover elements and four corner cover elements, the corner cover assembly may comprise any number of corner cover elements, e.g. dependent on the number of corners defined by the outer perimeter of the screening arrangement, and/or dependent on the amount openings needed to be covered.
  • This embodiment is particularly advantageous in screening arrangements in which a bottom profile is provided, to be connected to the side rails at the opposite ends relative to the top casing.
  • Such third and fourth corner cover element may then possess the same or corresponding features as the first and second corner cover elements, taking into account any differences between the top casing and the bottom profile.
  • the bottom surface and the top surface of the corner cover element may be part of the same element.
  • the bottom surface and the top surface may be provided by two different elements connected to each other.
  • the corner cover elements are formed by a top component and a bottom component, which may be formed by a 2K injection moulding process, where the two components are moulded together to be integrally connected with each other.
