Definitions

  • the present invention relates to a screening device adapted for mounting on a frame structure with frame members comprising top and bottom members as well as side members and lining an opening in a building, in particular a door or a window, the screening device comprising a top element, the top element comprising a roller tube and two mutually opposite end sections.
  • the present invention relates in a second aspect to a roof window with such a screening device.
  • US 4,228,843 A discloses such a screening device, which comprises a roll and a screening body as well as a cover adapted for being fitted onto the end of the roll with a pin extending from the end of the roll and extending through an aperture in the cover.
  • the cover is provided on the periphery of its end with a means, such as a pin, made for engaging a winder for turning the roll of the screening device.
  • EP 3 216 971 A1 discloses a further screening device.
  • the prior art screening devices have the drawback that the assembly of the mutually opposite end sections, and thus of the screening device, is cumbersome. Consequently, the mounting process is difficult, and the said assembly may not be completed correctly, which may lead to the screening device being damaged during the mounting process. Also, during use a screening devices are subjected to various forces which cause vibrations in the structure of the screening device. Therefore, if not assembled correctly, the end sections may be prone to becoming loose during use, or even falling apart, even at a relatively early point after mounting.
  • the prior art screening devices have the drawback that, if the assembly and mounting is not completed correctly, the end sections, and thus the screening device, may be unstable and prone to breaking over time.
  • a screening device adapted for mounting on a frame structure with frame members comprising top and bottom members as well as side members and lining an opening in a building, in particular a door or a window

  • a pin with a rectangular - or for that matter any other angular, such as triangular or hexagonal - cross section has the advantage of enabling insertion in a limited number of predetermined orientations only, thus further simplifying the mounting.
  • the rod element is any one of hollow and massive.
  • the at least one opening provided in the rod element is any one of an opening provided in the wall of the rod element, and an opening provided in a lug of the rod element, the lug being provided extending from a longitudinal end surface of the rod element.

  • a stop being in direct functional relationship with the pin is provided for.
  • a stop being in direct functional relationship with a transverse section of a pin such as a pin being T- or L-shaped, is provided for. Both embodiments thereby provide further robustness and durability to the connection.
  • At least one of the end piece and the inner piece of at least one of the two mutually opposite end sections are connected to the rod element by means of the pin in such a way as to allow for play between the end piece and the pin and/or the inner piece and the pin.
  • Such a play provides a means for absorbing vibrations caused by forces inflicted during use of the mounted screening device without compromising the connection between end piece and inner piece, respectively, and rod element. Thereby, a particularly robust screening device is obtained.
