Definitions

  • the roof window is intended for installation in a building, in particular in a roof of the building.
  • the roof window has the window frame, which is finally fixed in place with respect to the building, and the casement.
  • the casement is displaceable with respect to the frame, in particular rotatable about an axis of rotation.
  • the casement is preferably mounted on the frame.
  • the casement supports the glazing of the roof window.
  • the glazing can be designed as single glazing or as multiple glazing, in particular double glazing, triple glazing or quadruple glazing.
  • the glazing is bordered, for example, by casement spars of the casement, two vertical spars and two horizontal spars being provided in particular.
  • the wing frame spar mentioned at the outset is present as one of these wing frame spars.
  • the frame also preferably has two vertical bars and two horizontal bars. Two of the spars, that is to say the casement spars or the frame spars, are connected to one another, in particular each of the vertical spars is connected to each of the horizontal spars.
  • the sash frame spar is designed, for example, as a hollow plastic profile or has one.
  • the roof window can be a plastic roof window.
  • the hollow plastic profile is produced, for example, by extrusion or the like and subsequent cutting to length.
  • Another configuration of the wing frame spar can, however, also be implemented.
  • the casement frame spar is generally designed as a profile or hollow profile, which can in principle have any material or several materials.
  • wood, metal and / or plastic can be used as the material or materials.
  • several of the casement spars consist of an identical profile.
  • the vertical bars are made from the same first profile and / or the horizontal bars are made from the same second profile.
  • at least one of the horizontal bars has the same profile as one of the vertical bars or consists of the corresponding profile.
  • the profile has at least one hollow chamber, preferably a multiplicity of hollow chambers, which are separated from one another by stiffening webs. With such a configuration of the profile, high rigidity can be achieved with low weight.
  • the publication is, for example, from the prior art EP 2 738 339 A1 known.
  • a window such as a roof window with a frame, a sash, a window pane and a weatherproof and soundproofing system with cover elements, sealing elements and damping elements, two or more soundproofing and / or soundproofing elements being provided on the inside of a space.
  • the publication DE 43 20 321 A1 also describes a roof window with a frame of the window sash with cross profiles and longitudinal profiles and with a frame of the roof window with cross profiles and longitudinal profiles.
  • a transverse seal is provided, which covers the area adjacent to the inner upper edge of the cross profile of the frame of the window sash.
  • the seal has a plurality of sealing lips extending in the transverse direction of the transverse profile of the frame of the window sash, the distal ends of which lie against the glass pane of the window sash.
  • the sealing lips are penetrated by at least one capillary channel which runs transversely to their longitudinal extent and which allows a condensate drain from the inside of the lower cross profile of the frame of the window sash to the outside of the cross profile of the frame of the window sash.

  • the securing projection serves on the one hand to stiffen the casement frame and on the other hand to secure the glazing.
  • the safety projection preferably forms a fall protection for the glazing, so that even with a detaching connection between the glazing and the casement or the casement frame or a corresponding fastening, the glazing is removed from the casement due to gravity, in particular an uncontrolled crash of the glazing from the roof of the Building, is prevented by means of the safety projection.
  • the securing projection is preferably present on a lower horizontal spar of the sash frame, so that the sash frame spar defined at the outset is designed as such a lower horizontal spar.
  • the lower horizontal spar designates the horizontal spar or transverse spar of the casement lying at the bottom in the installed position of the roof window.
  • the glazing defines the glazing level. This preferably runs parallel to at least one glass pane of the glazing, in particular all glass panes of the glazing. In the context of this description, the glazing level is also to be understood as meaning planes parallel to the actual glazing level.
  • the securing projection at least partially overlaps the side surface of the glazing. The side surface is angled with respect to the glazing plane, in particular it is perpendicular to it.
  • the glazing is initially arranged at a distance from the securing projection, so that the side surface is spaced parallel to the securing projection.
  • the glazing only comes into contact with the securing projection when its fastening is released, which subsequently prevents the glazing from being removed from the casement by its supporting action.

  • the area 27 is configured, for example, in such a way that the sealing web 28, viewed in cross section, lies above the foot area 23. This can the free end of the sealing web 28 or the sealing wing 24 are at the same height as an upper side of the foot region 23.
  • the casement seal 14 is to overlap the window frame spar 4 at least in regions, in particular completely, as shown here.
  • the wing frame seal 14 particularly preferably projects beyond the window frame spar 4 in the direction facing away from the wing frame spar 5.
  • the roof window 1 rests with its sealing wing 24 on the frame member 4.
  • It is also particularly preferably in contact with a holding profile 29, which is fastened to the frame member 4 and serves to hold a covering frame sheet, not shown here.
  • the covering frame sheet engages in the holding profile 29 with a vertical web, also not shown.
  • an insulation block 30 can be arranged between the frame 2 and the sash 3, in particular between the frame spar 4 and the sash spar 5.
  • the insulation block 30 is preferably fastened to the casement spar.
  • the fastening web 26 is used, for example, which can be designed for the latching fastening of the insulation block 30 to the sash frame spar 5.
  • the wing frame seal 14, in particular its sealing wing 24, completely overlaps the insulation block 30 when the roof window 1 is closed. It preferably lies flat against the insulation block 30. Due to the overlap of the frame frame 4 by the casement seal 14, an air gap 31 present between the frame frame 4 and the casement frame 5 is separated from an external environment of the roof window 1. Accordingly, an excellent tightness of the roof window 1 is realized.
  • the Figure 2 shows a further representation of the roof window 1, wherein individual elements are cut or not shown at all.
  • another sash frame spar 32 connects to the sash frame spar 5, which is preferably designed as a vertical spar of the sash frame 3.
  • the sash frame spar 5 and the further sash frame spar 32 are fastened to one another, in particular fastened to miter surfaces.
  • a drainage channel 33 is at least partially formed in the sash frame spar 32.
  • the glass frame seal 13 has a passage recess 35, which continues to be part of the gutter 33.
  • the support area 18 or an upper side of the Support area 18 a bottom of the drainage channel 33.
  • the sealing lips 16 and 17 and the hollow profile 15 have been removed.
  • the securing projection 11 has a passage opening 36. This is designed in such a way that the moisture from the gutter 23 reaches an upper side 37 of the casement seal 14 and can be removed via this. The moisture is guided over the air gap 31 and over the frame 4 and can subsequently emerge from the roof window 1 downwards.
  • the sealing web 28 or its free edge forms a drip edge of the casement seal 14.
