Definitions

  • the invention relates to a window comprising a masking in a masking area, wherein a first region of the masking area is arranged to be switchable between an open and a closed configuration.
  • Patent document no. WO2009018828 A1 describes a functional mask, which comprises the functions of protecting gaskets situated between a pane and a frame from UV-irradiation or of contributing to promoting the attachment of the pane. Additionally to being a functional mask, the mask may also have an aesthetical purpose of achieving a better architectural whole of the window. Another example of prior art is shown in EP 3 348 737 A1 .
  • the present invention relates to a window, such as a roof window, for a building, said window comprising a window frame and a sash mounted thereon, wherein the sash comprises a pane module comprising at least a first glass pane and a see-through area,
  • the present invention provides a window being arranged to allow for installation of an optical sensor surface in an area, which is otherwise covered by the masking.
  • the window allows the customer to choose between two configurations of the window, one in which the masking in the first region is functioning as the masking in the second region and one in which the masking in the first region is at least partially removed, so as to allow installation of an optical sensor surface below the first region of the masking area.
  • the window may thereby be configured to be retrofitted with an optical sensor surface, for example, the customer may choose to retrofit a photovoltaic cell at a later stage, which is enabled by allowing the masking to be moved into the open configuration.
  • the invention may further allow the window and devices for the window, e.g. optical sensor device to be sold separately.
  • Open configuration is in the present disclosure intended to mean a configuration allowing more light to be transmitted through the masking area than in the closed configuration.
  • the closed configuration is generally a configuration in which the transmission of the light is substantially the same as the transmission of light through the second region of the masking area.
  • this can allow for substantially equal appearance to the human eye between the masking of the second region and of the masking in the first region in the closed configuration.
  • the masking area is arranged around the periphery of the pane module. According to the invention, the masking area is arranged along an edge of the pane module. An innermost border of the masking area may enclose and define the see-through area of the pane module.
  • the see-through area allows for light, e.g. sunlight to be transmitted from the exterior of the pane module to the exterior of the pane module, i.e. from the outside to the inside of a building in which the window is installed.
  • the window comprises several masking areas.
  • the masking areas may be separated by an area of the window not covered or comprising a masking.
  • a first masking area may be provided on a first side of the see-through area and a second masking area may be provided on an opposite second side of the see-through area and/or a first masking area may be arranged to cover the window frame and a second masking area may be arranged to cover the sash and/or a part of the pane module.
  • Each masking area may comprise one or more first regions and one or more second regions.

  • the masking area is defined in one plane, arranged substantially parallel to the major surface(s) of the glass pane(s) of the pane module.
  • one or more of the glass pane(s) may be curved, and the masking may either be arranged substantially parallel to one of the glass pane(s) at the edge or arranged substantially parallel to the façade or roof in which the window is installed.
  • the masking of the masking area is arranged to visually hide the parts of the window arranged directly below the masking, such as a part of sash and/or window frame, e.g. an interface between the sash and the window frame, wherein according to the invention, the masking area is arranged along an edge of the pane module and arranged to cover the pane module so that the masking reduces the visibility of at least a part of the sash and/or window frame.
  • the masking thereby provide a more aesthetically appealing window in which sides and frame components, such as gasket or seals etc. are hidden when viewing the window from the outside.
  • the masking is arranged to cover elements of the window arranged outside the see-through area.
  • the masking is preferably patterned or coloured, e.g. the masking may appear black to the human eye.
  • the masking may be provided by a coating, e.g. ceramic coating, lacquer, foil or by a plate structure, such as an opaque plate structure.
  • the masking may be arranged above and/or below the pane module, such as directly above and/or below a glass pane of the pane module with nothing in between, e.g. the masking may be arranged at the exterior side of the pane module and/or at the interior side of the pane module.
  • a masking of a first region may be arranged below the pane module, such as below a first or second glass pane, and a masking of a second region may be arranged above the pane module such as above the first glass pane, or vice versa.
  • the masking when the masking is arranged below the pane module. Additionally, preferably no elements are arranged between the masking and the part of the pane module, which it covers, so that the masking is fully visible through the pane module along the masking area.

  • the masking may be arranged to reduce or prevent transmission of sunlight by absorbing or reflecting a large portion of the sunlight.
  • the optical sensor surface may be arranged to be most effective in the same region of the light spectrum blocked or reduced by the masking, whereby there exist the need to remove the masking as an obstruction to the light.
  • the present invention allows for this by having the first region capable of being transferred into the open configuration.
  • the first glass of the pane module extends beyond the sash opening enclosed by sides of the sash.
  • the first glass pane of the pane module may additionally extend over the window frame opening provided by the sides of the window frame. In one or more embodiments, the first glass pane extends over the window frame sides, so as to cover the window frame sides from the outside.
  • the glass panes are substantially transparent to visible light, e.g. at least about 50% transparent, more preferably at least about 80% transparent, and most preferably at least about 90% transparent across at least the visible spectrum.
