Definitions

  • the present invention relates a roof window comprising a frame with a substantially flat light-transmitting plate, and more particularly to a roof window with one or more additional functionalities, such as for instance a water drainage functionality or a sunblind.
  • Embodiments of the invention have the object of providing a roof window with improved functionalities, and particularly a roof window with which the above described problems are wholly or partially obviated.
  • a first aspect of the invention relates to a roof window comprising a frame with a substantially flat light-transmitting plate.
  • the roof window is provided with a cleaning and/or wiping means mounted on or in the frame and drive means.
  • the cleaning and/or wiping means is configured and mounted to be moved reciprocally over the substantially flat light-transmitting plate for the purpose of cleaning the plate and/or removing rainwater on the plate.
  • the drive means are configured to move the cleaning and/or wiping means reciprocally.
  • Providing a cleaning and/or wiping means on or in the frame of a roof window enables the window to be cleaned at regular points in time and/or when rain is detected and/or on the basis of control signals, and the light-transmitting plate can thus remain clean without a window cleaner being needed.
  • the cleaning and/or wiping means and still more preferably also the drive means, are preferably accommodated in a module comprising a framework, wherein the framework is fixed on the frame of the roof window.
  • the module with the cleaning and/or wiping means and the drive means can be easily fixed on existing roof windows, without these requiring conversion.
  • the substantially flat light-transmitting plate is substantially rectangular with a first side and a second side lying opposite thereto, a third side and a fourth side lying opposite thereto.
  • the cleaning or wiping means is then preferably an elongate element extending from the third side to the fourth side.
  • the drive means are then preferably configured to move the cleaning or wiping means from the first side to the second side and back again.
  • the framework of the module has a third side and a fourth side which are parallel to the third and fourth side of the substantially flat light-transmitting plate, and guide means are provided in the third and fourth side of the framework for the purpose of guiding a first and second end of the elongate cleaning or wiping means during the reciprocal movement. In this way a robust device can be obtained which requires no or little maintenance and achieves a good cleaning of the plate.
  • the cleaning and/or wiping means can be fixed to the periphery of the light-transmitting plate for pivoting around a pivot point and can be configured to perform a rotating movement over the light-transmitting plate around the pivot point, for instance in the manner of a classic windscreen wiper in a car.
  • a plurality of cleaning and/or wiping means can be provided along the periphery of the light-transmitting plate, such that the whole surface area of the light-transmitting plate is cleaned and/or wiped.
  • the cleaning or wiping means preferably comprises a window wiper. It is however also possible to use a brush roller in addition to or instead of a window wiper, wherein the drive means are then preferably further configured to rotate the brush roller. Such a brush roller will allow elements adhering to the plate to be removed as well, and will thus further improve the cleaning of the plate.
  • the roof window further comprises a roller and a panel (also referred to as screen) which is connected thereto and can be rolled onto the roller and unrolled over the flat light-transmitting plate, and the drive means are further configured to roll up and unroll the panel over the flat light-transmitting plate.
  • the roller is preferably provided in the framework of the module.
  • the roller is preferably provided on a side of the plate, and the drive means are preferably configured to unroll the panel in the direction of an opposite side of the plate.
  • the roller can for instance be provided in a profile of the framework of the module, which extends along the second side of the light-transmitting plate.
  • the drive means comprise a carriage which is movable along the third side between the first and second side, which carriage is configured to be coupled in a cleaning or wiping position to the cleaning and/or wiping means for the purpose of moving the cleaning and/or wiping means from the first side to the second side and back again, and to be coupled in a panel position to the panel for the purpose of moving the panel from the second side to the first side and back again.
  • the drive means then for instance comprise a toothed belt driven by a motor and extending along the third side, wherein the carriage is coupled to the toothed belt.
  • first carriage is provided along the third side and a second carriage is provided along the fourth side.
  • first and second coupling can respectively be provided between the first and second carriage and a first and second end of the cleaning and/or wiping means.
  • These first and second couplings are preferably hinged couplings, still more preferably hinged couplings allowing a rotation around an axis directed vertically relative to the plane of the framework.
  • the coupling is preferably also configured to allow a certain variation in the distance between the first and the second carriage, so that the cleaning and/or wiping means can be placed at a slight angle relative to the direction of the first and second side. This slight angle for instance lies between 1 and 10°.
  • Such a coupling allows the cleaning and/or wiping means to be manually arranged in the framework in simple manner. This further also allows the first and second carriage to be controlled such that the cleaning and/or wiping means are placed on the flat light-transmitting plate slightly obliquely at the start of a movement, i.e. at a slight angle relative to the first and second side, such that the starting power at the start of the movement is smaller. This can be particularly advantageous for large roof windows.
  • the coupling can also be configured to uncouple the cleaning and/or wiping means when the distance between the first and second coupling is too great, for instance in the case of a control error, a coupling error or a failure of the drive means.
  • the panel has a first end edge which is connected to the roller and a second end edge which is held at a second location close to the roller, wherein an unrolling bar is provided on an inner side of the panel, such that the panel extends from the roller, over the unrolling bar and to the second location, and wherein the drive means are configured to move the unrolling bar over the light-transmitting plate.
  • the panel will be unrolled in a doubled state, i.e. two "panel” surfaces one above the other, over the light-transmitting plate.
  • the panel is then preferably provided with a pattern of more and less light-transmitting zones, and mounted such that in the unrolled state two surfaces of the panel extend over the light-transmitting plate and the two surfaces are displaceable relative to each other for the purpose of controlling the light incidence through the light-transmitting plate.
  • a pattern comprising alternately an opaque strip and a translucent strip can thus for instance be provided, wherein the strips are oriented parallel to the longitudinal direction of the roller.
  • the offset can be adjusted in simple manner by moving the unrolling bar away from the first roller to greater or lesser extent.
  • the unrolling bar can thus be moved to a position beyond the first side, and a small additional translation can there also be provided in order to adjust the light transmission of the panel.
  • Another advantage of providing an unrolling bar on an inner side of the panel is that it is possible to prevent dirt from also being rolled up when the panel is rolled onto the roller.
  • the panel is preferably provided on the rolls such that the panel extends from an underside of the roller to an underside of the unrolling bar, and then around the unrolling bar to an upper side of the unrolling bar, and then returns to the second location which is situated above the lower surface of the two surfaces of the panel lying one above the other, close to the roller. In this way dirt which is present on the panel when not rolled up will be discharged along the side of the unrolling bar, onto the roof window.
  • the carriage can be configured to be coupled in a panel position to the unrolling bar for the purpose of moving the panel, in a doubled state, to the first side.
  • first carriage is provided along the third side and a second carriage is provided along the fourth side.
  • first and second carriages are configured to be coupled to a first and second end of the unrolling bar via respectively a first and second coupling.
  • first and second couplings can be hinged couplings which allow a rotation around an axis oriented vertically relative to the plane of the framework (as described above), but can also be an "ordinary" coupling.
  • the panel has a first end edge connected to the roller and a second end edge connected to a second roller, wherein the roller is provided on a first side of the light-transmitting plate and the second roller is provided on a second, opposite side of the light-transmitting plate; wherein the drive means are configured to unroll the panel from the roller while it is being rolled onto the second roller, and vice versa. In this way the rolls are thus used as a scroll.
  • the panel can then be provided with at least a first and a second zone, each with a surface area substantially corresponding to the surface area of the light-transmitting plate, wherein the first zone differs from the second zone.
  • the different zones can thus for instance have a different light transmission. It is also possible to provide an "empty" zone, i.e. a zone where no cloth or screen is present, and light can thus enter freely through the panel. In addition, it is possible to provide zones with lighting elements, for instance OLEDs.
  • the roof window is provided with a rain sensor for detecting rain
  • the drive means are coupled to the rain sensor such that the wiping and/or cleaning means is moved when rain is detected.
  • the rain sensor can be configured to communicate wirelessly with a control which is coupled to the drive means.
  • the roof window is provided with a wireless receiver
  • the drive means are coupled to the wireless receiver such that the wiping and/or cleaning means and/or the panel can be moved in accordance with the wirelessly received signals.
  • the wireless receiver can form part of the above stated control, which is coupled to the drive means and is configured to control the drive means in accordance with the wirelessly received signals.
  • the roof window can be provided with one or more additional other sensors, such as a light sensor, a temperature sensor, a CO 2 sensor and so on.
  • the drive means are then preferably coupled to these one or more other sensors such that the wiping and/or cleaning means and/or the panel is moved in accordance with the detected signals.
  • the sensor can be configured to communicate wirelessly with a control which is coupled to the drive means.
  • the control then preferably comprises a wireless receiver, such that the control is able to control the drive means in accordance with the wirelessly received signals of the one or more sensors.
  • the drive means comprise a motor which is provided on respectively the first or second side of the framework, and the control is provided on respectively the first or second side of the framework.
  • the motor can more particularly be provided in a profile on respectively the first or second side of the framework, and the control can be provided in a profile on respectively the first or second side of the framework.
  • the control can for instance comprise a PCB and a so-called hub system connected thereto, wherein the hub system is configured to communicate, optionally wirelessly, with a plurality of devices, such as sensors, mobile devices such as a smart phone or a tablet, a domotic system and so on.
  • a user can then provide the control with instructions for controlling the drive means, for instance via his or her smart phone or tablet.
  • a program for instance an app, can for this purpose be installed on the smart phone or tablet (or on any other computer means which can be operated by a user) which allows the user to enter determined settings.
  • the framework of the module is formed by four hollow extrusion profiles, connected to each other by corner profiles, in which different components, such as the drive means and/or a part of the cleaning and/or wiping means and/or the roller, are accommodated.
  • the motor of the drive means and the roller can more particularly be provided in a hollow profile on respectively the first or second side of the framework, and the control can be provided in a hollow profile on respectively the second or first side of the framework.
  • the light-transmitting plate is a glass plate or polycarbonate plate.

  • frame 100 and light-transmitting plate 200 are substantially rectangular.
  • Frame 100 has a first side 101, a second side 102 lying opposite thereto, a third side 103 and a fourth side 104 lying opposite the third side.
  • light-transmitting plate 200 has a first side 201, a second side 202 lying opposite thereto, a third side 203 and a fourth side 204 lying opposite the third side.
  • Frame 100 is for instance mounted on an upstand O which is provided on a roof.
  • a possible embodiment of frame 100 and of upstand O is shown in more detail in figures 6 and 7 .
  • frame 100 are known, and are described in more detail in the Belgian patent applications BE 2016/5645 and BE 2016/5055 in the name of Glorieux, Jean Marc Gilles, which are included here by way of reference.
  • frame 100 can comprise a plurality of light-transmitting plates 200, 200' installed parallel to each other.
  • a module 1000 can be fixed on frame 100, for instance using four coupling pieces 600 which are attached to module 1000 on one side and to frame 100 on the other, for instance using screws. These coupling pieces 600 are preferably provided in the corners of frame 100.
  • Module 1000 comprises a framework 500 with a first side 501, a second side 502 lying opposite thereto, a third side 503 and a fourth side 504 lying opposite the third side.
  • a wiping means 300 is provided in framework 500. In the mounted state of module 1000 the wiping means 300 is configured and mounted to be moved reciprocally over light-transmitting plate 200 for the purpose of cleaning plate 200.

Wiping means 300 is movable in the direction of arrow P1 from first side 501 to second side 502 of framework 500 and back again. This movement of wiping means 300 is caused by drive means 400, which will be further elucidated hereinbelow with reference to figures 8A and 8B .

  • Wiping means 300 comprises an elongate carrier 310 in which is fixed an elongate wiping blade 320 manufactured from a flexible material, for instance a rubber or silicone material, see also figure 5A .
  • wiping blade 320 comprises a first elongate strip 321 protruding from carrier 310 in the direction of light-transmitting plate 200, and a second strip 322 which is connected to a lower edge of first strip 321.

  • Coupling 460, 460' is preferably also configured to compensate for a determined minimum difference in the distance between the first and the second carriage 450, 450' so that cleaning and/or wiping means 300 can be placed at a slight angle relative to the direction of first and second side 501, 502. This slight angle for instance lies between 1° and 10°.
  • Such a coupling allows cleaning and/or wiping means 300 to be manually arranged in framework 500 in simple manner, see figures 11A and 11B .
  • Coupling 460, 460' can also be configured to uncouple cleaning and/or wiping means 300 when the distance between the first and second coupling 460, 460' is too great, for instance when the first and second coupling 460, 460' come to lie too far apart as a result of for instance a coupling error (in the example only one carriage 450 is properly coupled to a coupling 460), see figures 13A and 13B .
