Definitions

  • the present invention relates to an external screening arrangement according to the preamble of claim 1.
  • the invention furthermore relates to a method of bringing such a screening arrangement from a supply condition to a mounted condition, and to a combination of such a screening arrangement and a roof window.
  • Screening arrangements positioned in front of windows to cover the window opening from direct sunlight in the screening position are common. Such screening arrangements are typically either positioned on the interior or the exterior side of the window opening to be screened.
  • Internal screening arrangements include roller blinds, Venetian blinds, pleated blinds etc. and are typically relatively easy to install, as the installation site is normally immediately accessible by the person carrying out the installation and the entire operation may be carried from the inside of the building in which the window is installed.
  • External screening arrangements are from the outset made from materials being sturdier and heavier than internal screening arrangements, and the installation site involves building parts located on the exterior side of the building. Screening arrangements also need to fulfil different requirements depending on whether they are installed in a façade window, i.e.
  • EP 2 650 463 A2 One example of a prior art document addressing the issue of facilitated mounting is EP 2 650 463 A2 .
  • return assemblies including rotatable return pulleys are detachably attached to the casing in an as-delivered state.
  • each return element comprises a base part connected to the guide part and to the side rail in a rotational connection around a second axis to allow for both the base part and the guide part to rotate around the second axis
  • each said return element comprises a pulley device in which the guide part includes one pulley, where the pulley is rotatable around said first axis, and the base part includes a pulley receiving part, said pulley being connected to the pulley receiving part such that pulley and the pulley receiving part are rotatable around the second axis, and wherein the second axis is substantially perpendicular on the first axis.
  • the side rails may be safely connected to the top casing of the screening arrangement without taking particular and time-consuming steps to ensure correct positioning of the guidance cord or cords of the cord system.
  • the return element By providing the possibility of the return element to rotate around a second axis, simply providing a tensioning force on the guidance cord or cords, typically occurring during first use of the external screening arrangement, the return element will act as a self-righting mechanism ensuring that any cord hassle due to less careful mounting is dissolved.
  • the first axis and the second axis may in principle be chosen such that they assume any angle between them, it is not foreseen that the axes coincide. Pulleys provide for a reliable and cost-effective solution with excellent mechanical performance.
  • the external screening arrangement may be an external flat roof window screening arrangement and/or an external inclined roof window screening arrangement.
  • the external screening arrangement may preferably be configured for being mounted on a roof window in an inclined roof and/or a flat roof.
  • the external screening arrangement is in a mounted condition mounted on a roof window, wherein said roof window is mounted in an inclined roof or a flat roof.
  • the pulley receiving part is rotatably connected to a stationary part connected to the side rail such that the second axis is substantially parallel to the longitudinal direction of the side rail. While configurations involving alternative positions of the pulley device, providing the second axis in a stationary part of the side rail and with the rotational axis parallel to the side rail has proven to function particularly well.
  • a method of bringing such an external screening arrangement from a supply condition to a mounted condition on the exterior side of a roof window with a window opening is provided.
  • a combination of such an external screening arrangement and a roof window with a window opening, a frame structure and a sash structure configured to extend in parallel to the roof surface, each with top and bottom members and two mutually parallel side members is provided.
  • a screening arrangement 1 in an embodiment of the invention, it is seen how the screening arrangement 1 comprises a screening body 11, a top casing 23 and a bottom profile 15.
  • the screening arrangement 1 is configured to be mounted on a roof window 2 (see Fig. 2a ) to assume a mounted condition, in which the screening body 11 is movable in a general longitudinal direction between a non-screening position and a number of non-screening positions in which the screening body 11 at least partially covers an opening of the roof window 2.
  • the screening arrangement 1 further comprises a roller shaft 14 ( Figs 3a and 3b ) accommodated in the top casing 23 and connected to drive means, the drive means being configured to rotate the roller shaft 14 in a winding direction W1 and an unwinding direction W2 (see Figs 3a and 3b ).
  • the screening body 11 has two side edges and a predefined length between a first end portion and a second end portion.
  • the first end portion is connected to the roller shaft 14 accommodated in the top casing 23 such that the screening body 11 may be wound on the roller shaft 14 in the non-screening position.
  • the second end portion is connected to a bottom profile 15.
  • the screening arrangement comprises two side rails 21, 22, a first side rail 21 and a second side rail 22 to guide at least opposing ends of the bottom profile 15.
  • the side edges of the screening body 11 may be guided in the side rails 21, 22.
  • the term "ends" of the bottom profile 15 is to be construed to encompass any structure of the bottom profile 15 suitable to interact with the side rails 21, 22, including separate elements and one-piece configurations.
  • the screening body 11 is shown in an unwound screening position, and in Fig. 1b the screening body is shown in a non-screening position, in which the screening body 11 is wound and stored on the roller shaft 14 in the top casing 23.
  • the bottom profile 15 may either be completely accommodated within the top casing 23, or protrude slightly therefrom.
  • the screening arrangement 1 is configured to be mounted on the exterior side of the roof window 2, which in turn is typically mounted in an inclined roof surface (not shown).
  • the roof window 2 has a frame structure 3 and a sash structure 4.
  • the frame structure 3 is configured to extend in parallel to the roof surface, while the sash structure 4 is configured to be opened to a variety of positions, for instance as shown in Fig. 2a .
  • the frame structure 3 and the sash structure 4 each has a top member 3a, 4a and a bottom member 3d, 4d and two mutually parallel side members 3b, 3c, 4b, 4c.
  • the sash structure 4 is pivotally connected to the frame structure 3 via hinges 5, in the shown embodiment here at a substantially central hinge axis, however other positions of the hinge axis are conceivable as well. Also visible in Fig. 2a is a pane 7 encased in the sash structure 4.
  • the side rails 21, 22 are connected to the sash structure 4 in a slidable and rotatable connection at or near the bottom of the sash structure 4.
  • the top casing 23 may either be rotatably or fixedly connected to the roof window 2, at or near the top of the frame structure 3.
  • the connection between the top casing 23 and the side rails 21, 22 is either fixed, i.e. the side rails 21, 22 are rigidly connected to the top casing, or rotatable, i.e. there is a hinge connection (not shown) between the top casing 23 and the side rails 21, 22. Examples of a roof window with a prior art screening arrangement are shown in the embodiments of applications EP 3 015 637 A1 and EP 2 390 455 A1 .
  • a fitting 6 is generally designated to indicate the slidable and rotatable connection between the bottom corners of the sash structure 4, defined by the bottom sash member 4d and the side sash members 4c, 4b, to the first side rail 21 and the second side rail 22, respectively.
  • the fittings 6 allow for the sash structure 3 to be guided along the side rails 21, 22 when the sash structure 4 is pivoted about its hinge axis when opening the roof window 2.
  • the top casing 23 comprises a slightly curved cover portion 232 and an end portion 233 at each of the longitudinal ends of the top casing 23. Furthermore, a solar panel 231 is placed in the top casing 23 which could be used to power the screening arrangement 1, possibly connected to a battery inside the top casing 23; however, power may also be provided from a main housing supply. Wiring, motor control and power means for the motor are not shown.
  • the top casing 23 is rotatably connected to the frame structure 3 of the roof window 2 with a top casing hinge 234.
  • the side rails 21, 22 are, at respective first fixed ends, rigidly, i.e. fixedly connected to the top casing 23 such that the side rails 21, 22 may pivot out of the plane defined by the roof surface and the frame structure 3 when opening the sash structure 4.
  • Figs 3a and 3b which show the operating principle and possible configurations of a cord system of embodiments of the screening arrangement 1 of the invention, two guidance cords 12 are provided to ensure parallel guidance of the bottom profile 15 during operation of the screening arrangement 1.
  • Each guidance cord 12 is, at one end, connected to a respective winding device including a winding reel 16, and, at another end, connected to a tensioning device generally designated 13 in the bottom profile 15.
  • the configuration of such winding reels are well-known as such, one example being found in the embodiment of Applicant's WO 2006/074653 A1 . It is noted that the term "in the bottom profile" should be interpreted in its broadest sense, thus including positions at or near a wall of the bottom profile, such as for instance behind a front wall of an open profile.
  • the guidance cords 12 are wound on the winding device oppositely relative to how the screening body 11 is wound on the roller shaft 14, i.e. when the roller shaft 14 rotates in the winding direction W1, the screening body 11 is wound, while the guidance cords 12 are unwound, and vice versa when the roller shaft 14 rotates in the unwinding direction W2.
  • the winding device including the winding reel 16 and the roller shaft 14 are both accommodated in the top casing 23.
  • the winding reels 16 should unwind/wind a length of guidance cord 12 substantially equal to the length of screening body 11 wound/unwound by the roller shaft 14 when the bottom profile 15 is moved in the general longitudinal direction of the screening arrangement 1 as defined by the screening body 11 and the side rails 21, 22.
  • the guidance cords 12 are slackened, thereby impairing the parallel guiding function.
  • the tensioning device 13 provides a tension on the guidance cords 12 such that during operation, variations in the required length of the guidance cords 12 is accommodated for.
  • the winding reel 16 is arranged at one end of the roller shaft 14.
  • the winding reel 16 can however, also be arranged inside the roller shaft 14 as shown in Fig. 3b , such that the roller shaft 14 and thus also the screening body 11 may be made wider, or two winding reels, one at the respective end of the roller shaft 14.
  • Figs 3a and 3b Also visible in the general overviews of Figs 3a and 3b are return elements 10 for guiding the respective guidance cord 12 from the winding reel 16 around the associated return element 10 and up to and into the bottom profile 15, and further to the tensioning device 13. Since the return element 10 is located at or near the free end of the respective side rail 21, 22, this means that the returning or upwards directed part of the guidance cord 12 runs alongside the downwards directed part of the guidance cord 12 from the winding reel 16 to the return element 10. The upwards directed part of the guidance cord 12 may run in the same track of the respective side rail 21, 22 as the downwards directed part of the guidance cord 12. In the embodiment shown in one and the same track 221 (cf. Figures of specific embodiments) of the side rail 22.
  • the screening arrangement comprises an external screening arrangement with a substantially flat screening body also known as a panzer as seen in the unwound screening position, but the concept is applicable also to other forms of screenings such as awning blinds, external roller blinds, roller shutters with various types of lamellae etc.
  • top casing 23 Details of the top casing 23 in the embodiment shown are shown in Figs 4a and 4b .
  • the first end portion of the screening body 11 is connected to the roller shaft 14 accommodated in the top casing 23.
