Definitions

  • the window frame is a very important item in the heat transfer through the window. This affects both the overall thermal transmittance and the surface temperature on the frame and edges of the glazing. Therefore, to significantly improve the roof windows, in addition to the installation of a higher-quality glazing unit, it is necessary to significantly improve the frame. Insufficient temperature on the surface of the frames can, under unfavorable circumstances, lead to surface condensation of water vapor with unacceptable accompanying phenomena of mold growth, which is both a hygienic and aesthetic problem.
  • roof windows opening by sliding the casement to a position outside the window opening are used to a very small extent.
  • a solution is known in which the casement is slid to one side guided on pull-out rails or using other guide elements (e.g. CN101080019003A , CN207700554U , FR2335666A1 , CH633852A5 , US4064649A ).
  • Such casement movement without lifting does not allow a roof casement design where its outer contour would extend on all sides over the outer contour of the fixed window frame when viewed from the exterior.
  • pull-out rails or other metal guide elements reduce the possibility of ensuring integrity of thermal insulation on the junction of the fixed frame and the casement.
  • EP2843149A1 describes a solution using a parallelogram principle for the opening mechanism, so that the casement is lifted from its position in a closed state by a semicircular movement and is positioned on the side of the window opening in the fully open state.
  • the window casement in the closed state is mounted with its exterior surface in the plane of the exterior surface of the roof, i.e. it fits into the window opening formed by the fixed frame fitted in a recess below.
  • the elements of the opening mechanism are positioned between the inner side of the frame and the outer side of the casement. Rainwater ingress is prevented by simply overlapping the glass on the outside over the gap between the casement and the fixed frame, because the casement frame does not overlap over the fixed frame when viewed from the exterior.
  • the opening mechanism comprises a first rod which is provided at one end with a frame joint of the first rod which is rotatably attached to the frame profile. At the other end the opening mechanism is provided with a casement joint of the first rod which is rotatably attached to that casement profile which corresponds to said frame profile and abuts against it in the closed position.
  • the opening mechanism also comprises a second rod which is provided at one end with a frame joint of the second rod which is rotatably attached to the frame profile and at the other end is provided with a casement joint of the second rod which is rotatably attached to the casement profile which corresponds to the frame profile and abuts against it in the closed position.
  • the roof window also comprises frame fittings and casement fittings.
  • each casement profile to which the rods are rotatably attached in the closed position of the window, is configured with an overlap over its respective frame profile, against which it abuts in the closed position.
  • This overlap is positioned above a part of the opening in the fixed frame, and on this overlap the casement fittings are firmly affixed from below for attaching the casement joint of the first rod and for attaching the casement joint of the second rod.
  • the frame fittings are firmly attached to the frame profile for attaching the frame joint of the first rod and for attaching the frame joint of the second rod.
  • Figure 2e depicts section D-D of a part of the roof window in a closed position according to Figure 2a .
  • Sections 2c, 2d and 2e also show one of the opening mechanisms and these sections are drawn in a position where the window lies with the fixed frame downwards on a horizontal base.
  • Figures 2d and 2e some reference signs are omitted for the elements already depicted in the previous figures.
  • Figures 2c, 2d and 2e capture only one of the possible advantageous shapes of the frame and casement profiles, corresponding to Figure 1c .
  • the figures also depict the outer side wall 7.4 of the frame profile 7 , which faces the roof construction when the window is installed into the roof construction 1.
  • this outer side wall 7.4 of the frame profile 7 is perpendicular to the horizontal base on which the window lies, in more complex embodiments according to Figures 1d and 1e the outer side wall 7.4 of the frame profile 7 may also comprise horizontal sections.
  • each casement profile 8 on its side facing away from the opening in the fixed frame 2 , comprises such a protrusion.
  • this protrusion is arranged to cover at least a part of the outer side wall 7.4 of the opposite frame profile 7 against which the casement profile 8 abuts, and this along at least half the length of the respective opposing frame profile 7 .
  • the present invention combining opening mechanisms 6 with a parallelogram and a vertical overlap b can be used for roof windows of any shape. In practice, however, windows in the shape of a parallelepiped, typically a rectangle, are usually used. For parallelepiped-shaped windows, in the closed position, at least one pair of frame profile 7 and the abutting casement profile 8 is parallel to another pair of frame profile 7 and the abutting casement profile 8.
  • the roof window preferably also comprises frame fittings 6.3 and casement fittings 6.4 , which are also indicated in Figs. 2c, 2d and 2e . It can be seen that in the closed position of the window and at the same time in the position where the roof window lies on a horizontal base with the fixed frame 2 downwards, each casement profile 8 to which the rods 6.1 , 6.2 are rotatably attached, overlaps the frame profile 7 against which it abuts in the closed state, horizontally in the direction of the space above the opening in the fixed frame 2 , and this at least in the area for mounting the frame fittings 6.3 and the casement fittings 6.4 .
  • this overlap of the casement profile 8 over the frame profile 7 towards the space above the opening in the fixed frame 2 can also be longer, for example along the entire length of the casement profile 8.
  • casement fittings 6.4 are fixed from below for fixing the casement joint 6.6 of the first rod 6.1 and for holding the casement joint 6.8 of the second rod 6.2 .
  • Under the casement fittings 6.4 are fixedly mounted to the frame profile 7 frame fittings 6.3 for attaching the frame joint 6.5 of the first rod 6.1 and for attaching the frame joint 6.7 of the second rod 6.2 .
  • Figures 3b, 3c show a detail of a pair of frame profile 7 and casement profile 8 in a shape which, except for the beveled upper corner, corresponds to the schematic Figure 1d .
  • Figures 3b, 3c furthermore show in detail the preferred material structure of the two profiles 7 , 8 .
  • the opening casement 3 can be locked in various positions of opening the window, including a very small stroke of the opening casement 3 , which enables influencing the air flow.
