Definitions

  • a screening arrangement for a roof window, and roof window comprising such a screening arrangement.
  • the invention relates to a screening arrangement according to the preamble of claim 1.
  • the invention furthermore relates to a roof window comprising such a screening arrangement.
  • Screening arrangements also 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.
  • the manufacturing of the screening arrangement may be quite a complicated process with small margins for errors.
  • small clearances may be present during assembly, e.g. when connection or otherwise introducing components into each other. These small clearances may lead to nicks and bump being created by unwanted contact in-between components. Alternatively, an additional amount of time or steps is needed to avoid the small clearances being problematic.
  • a screening arrangement of the kind mentioned in the introduction, which is furthermore characterised in that the screening arrangement comprises a winding device comprising at least one winding reel in connection with or connectable to the roller bar at the first longitudinal end of the roller bar, that the top casing comprises a bottom end element and a top end element adjacent to the first longitudinal end of the roller bar and further delimiting the bar space, the bottom end element and the top end element delimiting a reel space accommodating and limiting movement of the at least one winding reel, and that the bottom element of the top casing is configured to receive and support the roller bar during assembly of the screening arrangement and the top element is configured to be connected to the bottom element subsequent to the bottom element receiving the roller bar.
  • the ease of assembling the top casing is improved.
  • the roller bar does not need to be introduced along an opening in the top casing, instead the top casing is formed around the roller bar.
  • the handling of the roller bar is eased during assembly of the screening arrangement. Since the winding device comprising a winding reel at one or both ends of the roller bar is present, the formation of a space limiting movement of the winding reel, the assembly of the screening device is further eased as the risk of unwanted movement of winding reel(s) during assembly is minimized.
  • the at least one winding reel comprises engagement means adapted for connecting the at least one winding reel to the roller bar, wherein the bottom end element and the top end element are configured to form an engagement through-hole extending from the reel space to the bar space, and wherein the engagement means extends through the engagement through-hole and into the roller bar. Consequently, the top casing is formed in a simple and efficient manner where movement of the winding reel and the roller bar is limited, while still allowing the roller bar and the winding reel to be connected to each other.
  • the engagement means are formed as one or more snap-legs engaged in a snap-connection with one or more corresponding connectors in the roller bar. Consequently, the winding reel may be connected to the roller bar by simply inserting the engagement means into the roller bar.
  • the connection between the roller bar and the winding reel does not need tools for being formed, thus simplifying assembly, and obviating the need for additional space to accommodate a tool.
  • the top casing comprises an end cover further delimiting the reel space.
  • the end cover may also provide support for the winding reel.
  • a through-hole is formed in the end cover aligned with the engagement through-hole formed by the bottom end element and the top end element to allow drive means to be inserted through the through-hole and the engagement through-hole into the roller bar.
  • the end cover comprises one or more second support surfaces supporting the winding reel and facilitating rotation of the winding reel in the winding direction and the unwinding direction. This ensures suitable rotational support for the winding reel.
  • the bottom end element and/or the top end element comprises one or more first support surfaces supporting the winding reel and facilitating rotation of the winding reel in the winding direction and the unwinding direction. Consequently, movement of the winding reel is facilitated, which in return facilitates movement of a screening body.
  • the top and bottom elements may be connected to each other in any suitable way, as long as they allow for initial reception of the roller bar by the bottom element during assembly.
  • the bottom end element is connected to the bottom element and the top end element, wherein the top end element is connected to the top element, and wherein the bottom element is connected to the top element via the bottom end element and the top end element. This facilitates the assembly of the screening arrangement even further.
  • the bottom end element and the top end element each comprises a plurality of connectors for connecting the bottom end element to the bottom element and for connecting the top end element to the top element.
  • Suitable connectors include releasable engagement means including screws and openings, but could also include snap or frictional engagements means.
  • the bottom end element is connected to the top end element by a set of connectors, preferably including a first, pivotal connection, more preferably also in a also in second, releasable connection.
  • a pivotal connection provides for a particularly simple mounting, since the elements are easily fit into the assembled position.
  • the winding device forms part of a cord system comprising a set of cords, the at least one winding reel, and optionally return elements and/or tightening means for the cords.
  • the cord or cords of the cord system may either be wound on the winding reel before assembly of the winding reel with the respective end of the roller bar, or later, i.e. once the winding reel is located in the reel space.
  • two winding reels are present, one at each longitudinal end of the roller bar.
  • the screening arrangement could in principle be used to screen an arbitrary opening, it is preferred that the screening arrangement is adapted for a skylight or roof window. In such structures, the possible assistance from gravity forces during unwinding of the screening body is negligeable.
  • a method for assembling a top casing with a roller bar for a screening arrangement comprising the steps of:
