Definitions

  • the adjustment system provides a system for adjusting the roof window for different roof inclinations.
  • the spring assembly When the spring assembly is coupled to the sledge one or more springs in the spring assembly exerts a pulling force on the sledge. This results in the first end of the lifting arm experiencing a pull and a rotation around the connection point with the adjustment arm. As a result, the lifting arm is forced into a position with its longitudinal end substantially perpendicular to the sliding direction of the sledge in the sledge guide resulting in an opening of the roof window.
  • the force exerted by the lifting arm on the secondary frame is related to the positioning of the secondary lifting arm relative to the lifting arm and spring.
  • the roof window can be balanced to a roof inclination in the range of 15° - 65°.
  • the adjustment system may comprise an adjustment screw.

  • the adjustment system may further comprise an adjustment bushing wherein the second end of the adjustment arm is connected to the adjustment screw through the adjustment bushing, such that the adjustment bushing is configured to move axially on the adjustment screw.
  • the adjustment bushing allows for minimum friction connected between the adjustment screw and the adjustment arm. As the adjustment arm is adjusted on the adjustment screw, the angle between the adjustment arm and the lifting arm changes. Simultaneously, the angle between the adjustment arm and the adjustment screw may change.
  • the bushing provides a suitable mechanism that allows such a rotation.
  • the bushing may comprise a cylindrical or cyclical body engaging with the adjustment screw via a through hole.
  • the through hole of the adjustment bushing may have an inner geometry to engage with an outer bushing of the adjustment screw.

  • a sledge wheel may allow steering of the sledge along the length of the sledge guide.
  • the sledge wheel may be provided substantially next to the connection between the sledge and the lifting arm.
  • the lifting arm may be connected to the sledge through the sledge wheel. By providing the sledge wheel close to the lifting arm, a greater stability of the sledge is achieved.
  • the sledge wheel may additionally add support for the sledge in the sledge guide.
  • the sledge may additionally and/or alternatively be provided with one or more runners.
  • the one or more runners mounted on the sledge may provide additional support for the sledge in the sledge guide.
  • the runners may be made of a polymer.

  • the spring assembly 20 and the sledge 30 are then coupled by opening the roof window resulting in the sledge 30 sliding towards a coupling device such as a hook attached to a spring comprised in the spring assembly 20. Opening the roof window results in the sledge 30 engaging with the hook, as shown in Fig.
  • the sledge 30 will slide back in a direction away from the spring assembly 20 and the spring now coupled to the sledge 30 will exert a pulling force on the sledge 30 and provide a resistance against the closing of the roof window.
  • the pulling force of the spring and the weight of the roof window are preferably balanced such that the roof window can be positioned in an open position without closing due to its own weight or opening further due to the pull from the spring in the spring assembly. This balance is also influenced by the roof inclination of the roof that the roof window is installed in.
  • the spring in the spring assembly 30 may be adjusted to balance the roof window for a specific roof inclination.
  • the spring force acting on the sledge will not be balanced to the weight of the window.
  • the spring may exert to much force on the window thereby forcing the window to open further.
  • the spring is too weak, and the window will close due to its own weight. Both scenarios are both uncomfortable for the user and potentially hazardous.
  • an adjustment system as shown in Figs. 2 - 3 and 6 - 11 is comprised in the roof window. The adjustment system is installed to adjust the position of the second end of the adjustment arm 52 in the sledge guide 16.
  • a sliding disc 43 on the lifting arm 14 is present.
  • a further sliding disc may be arranged on the other side of the lifting arm 14 as well. The sliding disc reduces the distance to the sledge guide 16 and adds stability to the lifting arm as it travels from an open to a closed position or vice versa.
  • An adjustment rivet 57 - better shown in Fig. 3 - connects the lifting arm 14 to the adjustment arm 52 firmly, while enabling their rotational movement with respect to each other.
