Description

The invention relates to a living roof window with a sash, which has a folding assignable to a glazing.

Roof windows of the type mentioned have a sash with the four sides of a rectangular, in particular insulating glass panes having associated frame profiles, each frame profile is formed with a U-shaped receiving recess for the glazing. A side surface of the respective receiving recess forms a fold for the glazing. In the production of the sash window of the residential roof window, the four frame profiles are supplied to the four edges of the glazing side, whereby the edge regions of the glazing come to rest within the U-shaped receiving recesses. Now, the four frame profiles are connected together in the corner areas. A balance of different strengths of selectable glazing variants is achieved by the use of correspondingly high glazing gaskets on the glazing outside. Thus, the inner glazing plane, in particular the plane of the inner insulating glass pane, is always in the same position with different glazing thicknesses, with stronger glazings correspondingly applying to the outside. Very thin glazings, for example vacuum insulating glass packages, can not be used because of their small package thickness in the known roof canopy, because the necessary glazing pressure can not be applied due to the very high sealing profile required for this purpose. Furthermore, the external appearance suffers from the high profiles.

If in the course of this application is spoken "inside" and "outside", this is in particular related to the installation state of the residential roof window, that is, internal structures are associated with the space and external structures of the outside atmosphere.

The invention has for its object to provide a living roof window of the type mentioned, which is easy to manufacture, simple design, visually appealing and / or suitable for thin glazing.

This object is achieved in that the fold is designed to compensate for different strengths of the glazing as Verstellfalz. By adjusting the fold, it is possible to arrange this according to the thickness of the glazing, whereby always optimal coordination of the components can be carried out on each other and a simple structure and a corresponding visual effect is achieved. Furthermore, the adjustable and thus separate fold allows the four frame profiles of the sash to be connected together before the glazing is placed in the sash. Once the glazing has been installed, the adjustment rebate can then be mounted.

In particular, it is provided that the adjustment fold is an inner fold. This has the consequence that the position of the inner fold can always be adapted to the thickness of the glazing, so that the outer surface of the glazing can always be arranged in the same position within the sash frame, thus applying stronger glazing inwards. Consequently, the same conditions always apply to the outside, regardless of whether thinner or thicker glass packages are used.

According to a development of the invention it is provided that the Verstellfalz is designed as a form-fitting. Consequently, it has in its different possible adjustment positions in each case a positive connection to a frame element of the sash.

Alternatively it can be provided that the Verstellfalz is designed as Reibschlussfalz, that is, it is arranged to take in accordance with different positions by overcoming a frictional engagement slidably on the frame member of the sash.

A development of the invention provides that the Verstellfalz is provided with fastening means which can cooperate with staggered arranged on the frame member of the sash frame / counter-fastening means. The counter-fastening means are preferably offset in the direction of a glazing surface normal to each other. The glazing area standard is an imaginary direction that is perpendicular to the plane of a glass sheet of the glazing. In this direction, the counter-fastening means are staggered / arranged, so that the fastening means cooperate to adapt to different thicknesses of the glazing with Gegenbefestigungsmittein appropriate positions and therefore can keep the Verstellfalz positionally adjusted.

A development of the invention provides that the Verstellfalz has plug-in means that can cooperate in selectable insertion depth with mating plug means of the frame member of the sash. Depending on the insertion depth results in the position of the adjustment and thus the corresponding adjustment to the strength the glazing. When using fasteners / counterfasteners, the adjustable rebate can be positioned in stages to match the thickness of the glazing. In the plug-in / mating plug means a continuous adjustment of the position of the adjusting is realized.

It is advantageous if the fastening means, counter-fastening means, plug-in means and / or counter-plug means are provided with latching means and / or counter-latching means. The latching means and / or counter-locking means allow a backup of each selected position of the adjusting, so that it is firmly and securely arranged on the casement.

According to a development of the invention, a glazing is provided, the outer surface of which is always arranged in the same position in the casement regardless of the thickness of the glazing. Stronger glazings consequently lead to their further application on the inside. This more or less strong application is compensated / collected by the corresponding arrangement of the adjustment. The term "Verstellfalz" within the meaning of the invention, a fold is to be considered, which is always arranged in the same position on the frame member of the sash, but in itself adjustable or changeable so that it is adapted to the corresponding thickness of the glazing. This can be done, for example, by having breakable edge regions at various positioned predetermined breaking lines, so that only breaking off of at least one correspondingly wide edge region for adaptation to the glazing can always take place. Alternatively, it is also possible, as Verstellfalz a fold from a selection of Select different high folding, so that the selection is done by the "adjustment".

According to a development of the invention it is provided that the Verstellfalz is provided with a glazing seal. As a result, a sealing closure is created between the fold and the associated glazing surface.

The glazing can be designed in particular as insulating glass package. It is advantageous if the glazing is designed as a stepped insulating glass package. This has, in particular at one edge region, a glass pane of greater length than at least one further glass pane, in order thereby to be able to cover areas of the casement. Through this cover, a projection is created, for example, the safe rainwater drainage is used. In such a case, the supernatant is located in the lower part of the residential roof window and prevented by its supernatant the ingress of moisture.

It is advantageous if the Verstellfalz is a retaining fold or a Abdeckfalz. In the case of a retaining fold, an edge region of the glazing is supported thereon so that the corresponding position of the glazing is defined by the support and a holding function / support function is exerted on the glazing. If it is at the Verstellfalz a Abdeckfalz, it serves only to create the optical transition between sash and glazing and thus exerts so far no or only small holding or supporting function.

In particular, the wing frame may be associated with a holding profile or cover profile. This is on the outside, is accordingly in the region of the outside of the glazing and is used in the case of a holding profile for supporting the glass package or in the case of training as a cover profile as an optical aperture, which exerts no or only a small holding or supporting function.

In particular, it can be provided that the retaining profile and / or the cover profile formed on the casement, in particular integrally formed, or is removably attached. The retaining profile and / or the cover can be assigned a glazing gasket to prevent the ingress of moisture.

a sectional view through the wing of a residential roof window according to another embodiment.

FIG. 1 shows, in section, a side region of a residential roof window 1. The residential roof window 1 has a casement 2 and a window frame 3. The casement 2 has a frame element 4, a fold 5 and a glazing 6. The frame 3 has means 7 for supporting and guiding the sash 2 and an outer profile 9 provided with a seal 8. The outer profile 9 and the outer side of the frame element 4 are covered by a sheet metal cover 10 arranged in a displaceable manner. In the installed state is followed by the roof canopy 1, a connection to the roof producing enclosure 11.

The fold 5 is formed as Verstellfalz 12, since it is fastened to compensate for different thicknesses of glazing 6 in different positions on the frame member 4. The adjustment fold 12 forms an inner fold 13, because it is assigned to the inside of the living roof window 1, ie the room side. It projects beyond the side 14 of the frame element 4 so that it covers the edge region 15 of the inside 16 of the glazing 6, as can be seen in FIG.

In the figures 1 to 9 is always only a sectional view of a side or a sectional view of the lower transverse spar portion of roof windows 1 is shown. Of course, corresponding embodiments are also in the other frame elements of the respective rectangular roof windows, but for the sake of simplicity is not discussed separately.

The Verstellfalz 12 is formed in cross-section substantially L-shaped, since it has a first leg 17 and a second leg 18. Also, the frame member 4 has - viewed in cross section - an L-shape with a third leg 19 and a fourth leg 20.

On the side 21 of the first leg 17, this fastening means 22 in the form of two side-facing, spaced mutually extending, strip-shaped projections 23 (Figure 2) which in counter-fastening means 24 in the form of on the side 14 of the third leg 19 of the frame member 4th trained grooves 25 intervene. Two further grooves 26, which also belong to the counter-fastening means 24, are located at a greater distance from the plane of the glazing 6 on the third leg 19. A comparison of Figures 1 and 2 shows that in the side region and in the lower region of the residential roof window with respect to the Verstellfalz 12, the fastening means 22 and counter-fastening means 24 are the same configurations. The window frame 3 is formed slightly differently in the lower area of the residential roof window (Figure 2) with respect to the side area (Figure 1), but this is not relevant to the invention. In Figure 2, the outer portion of the frame member 4 is designed such that not - as in Figure 1 - a step-shaped receptacle for the edge of the glazing 6 is formed but the outwardly facing sides of Verstellfalz 12 and frame member 4 are aligned to each other, so that an outer pane 27 may extend beyond the sash 2 and window frame 3 also to form a moisture protection. The outer pane 27 forms, together with an inner pane 28, the glazing 6, which is designed as insulating glazing 29, namely an insulating glass package 30. Since the outer pane 27 projects beyond the inner pane 28 in the lower region, such an arrangement is also called a step insulating glass pack 31.

According to the above explanations, the adjusting fold 12 is located in the zone of the inner edge region 15 of the glazing 6. If the glazing 6 is supported on the adjusting fold 12 and the glazing 6 thereby gives a hold or additional hold, the adjusting fold 12 acts as a holding fold 32. However, embodiments are also conceivable in which the adjusting fold assumes no holding function or holding function for the glazing 6, since the glazing is connected exclusively to the frame element 4 (in particular by gluing), so that the adjusting fold 12 only visually makes an edge covering of the glazing 6 and therefore forms a Abdeckfalz. Between the Verstellfalz 12 and the glazing 6, a glazing seal (not shown in the figures) may be arranged.

FIGS. 3 and 4 show the living roof window 1 of FIGS. 1 and 2 in a corresponding manner, so that reference is made to the above explanations and FIGS. 1 and 2. The only difference is that in the figures 1 and 2, a glazing with a low thickness (in particular 10 mm) was used (such a thin glazing can, for example, as a vacuum glazing be formed) and on the other hand in Figures 3 and 4, the canopy window 1 has been equipped with a stronger glazing 6, for example, has the thickness of 24 mm. In order to realize according to the invention that the glazing 6 does not apply to the outside but to the inside, that is to say in the direction of the space due to a greater thickness, the adjusting fold 12 is offset relative to its position in FIGS. 1 and 2 in FIGS. 3 and 4 in such a way that its projections 23 no longer engage in the grooves 25, but in the grooves 26 located further inside. The second leg 18 of the Verstellfalzes 12 continues to bear against the fourth leg of the frame member 4, in order to not occur in this way no unsightly gap despite the displacement of Verstellfalzes 12. A comparison of Figures 1 and 2 with Figures 3 and 4 shows that despite the thin or stronger glazing 6, the outer pane 27 occupies the same position relative to the sash 2 in both embodiments and that only the inner pane 28 has changed its position, however you However - by the offset of Verstellfalzes 12 - this is assigned directly to the inside. A comparison of Figures 3 and 4 shows that the corresponding offset of Verstellfalzes 12 was carried out not only in the side area, but of course in the lower part of the residential roof window. Of course, this displacement also applies to the other side of the residential roof window and also to its upper area.

The embodiment of Figures 5 and 6 differs from the embodiments of Figures 1 and 2 and 3 and 4 only in that now an even stronger Stufenisolierglaspaket 31 has been used. In order to ensure according to the invention that the outer plate 27 still retains the position, the Verstellfalz 12 was further offset inwards so that it engages with its outer projection 23 in the most inwardly disposed groove 26 and engages with the further projection 23, the inner edge of the leg 19. The glazing thickness in the embodiment of Figures 5 and 6 is 28 mm.

While in the embodiments of Figures 1 to 6 interlocking means (projections 23, grooves 25, 26) are provided for the fastening means 22 and counter-fastening means 24 to allow a gradual displacement of Verstellfalzes 12 so that it forms a form-fitting 33, is in the Embodiment of Figures 7 and 8 provided that the Verstellfalz 12 is slidably mounted in the direction inwards or outwards and therefore forms a Reibschlussfalz 34. Optionally, the displacement may be provided with locking means to obtain a plurality of secured positions. On the frame member 4, an outwardly facing guide projection 35 is formed, in which a guide groove 36 of the adjusting 12 engages. On one side of the guide groove 36, the Verstellfalz 12 has a filling zone 37 and on the other side a viewing zone 38, wherein the filling zone 37 more or less far into a pocket 39 of the frame member 4 engages and the Sichtzone 38 more or less far the Visible side 40 of the frame member 4 covered, wherein the intervention and covering is dependent on the position of Verstellfalzes 12 relative to the sash 2. In Figure 7 is a very thin glazing 6, so that the guide projection 35 engages only a portion in the guide groove 36. In the embodiment of Figure 8, a much stronger glazing 6 is installed in the living roof window 1 and therefore the Verstellfalz 12 so far inward displaced that sufficient space is created for the glazing 6. It can be seen that the guide projection 35 now fully engages in the guide groove 36. The outer pane 27 of the glazing 6 has according to the comparison of Figures 7 and 8 always the same relative position to the sash 2, that is, the thicker insulating glass package 30 of Figure 8 carries further inward, so the space side, but not on the outside on.

FIG. 9 shows a further exemplary embodiment of the invention, but here only the sash frame 2 of a residential roof window 1 is shown. It can be seen that a glazing 6 is arranged in a stepped receptacle 41 of the sash frame 2 and the inside edge region of the glazing 6 is assigned a Verstellfalz 12, which forms a visual cover and is therefore designed as Abdeckfalz. The Verstellfalz 12 has by means of predetermined breaking lines 42 removable / breakable areas 43, which can be removed depending on the thickness of the glazing 6 in order to produce a closed optical transition (without striking gap formation) to the glazing 6. In this respect, it is due to this adjustment possibility at the fold 5 also a Verstellfalz 12. In particular, it can be provided that the Verstellfalz 12 according to Figure 9 by means of locking means 43 'on the frame member 4 of the sash 2 is releasably held. Furthermore, it can be seen from FIG. 9 that an outer holding profile 44 is arranged on the casement 2 in order to form the receptacle 41 in order to provide a support for the glazing 6 to the outside. Accordingly, according to FIG. 9, the glazing 6 can be fastened by gluing to the retaining profile 44 and also by gluing the frontal region of the glazing to the casement 2. If the retaining profile 44 no Abstütz- or supporting function for the glazing 6 makes, but only makes an optical cover to the outside, it is in the holding profile only a cover profile. Retaining profile and / or cover profile can be removably attached to the casement 2 or, however, integrally formed with the casement 2 or attached to this not removable.

Due to the inventive design is due to the Verstellfalz 12 an internal device to compensate for different strengths of the glazing 6 / compensate. Differently thick glazing 6 accordingly affect the view of the sash profile of the sash 2 from the inside. Outside there are no differences, so that in particular a secure seal can be ensured. If the Verstellfalz 12 assumes holding functions for the glazing, there is virtually a Glashalteleiste. The Verstellfalz 12 may be positively, frictionally and / or materially connected to a frame member 4 of the sash 2. Due to the invention, with glazing of varying thickness, no glazing frame (pressure glazing) is required on the outside. There are therefore leakage advantages and a uniform appearance. Even very small glass thicknesses (for example, 10 mm for vacuum glazing) can be used without difficulty. Very low component heights can be realized in connection with step insulating glass packages 31, since a glass projection on the sash profile at the bottom with the outside glass pane (thickness about 4 mm) is possible and does not have to survive the entire glass package (thickness 10 to 30 mm). The supernatant is used for safe water removal downwards and thus ensures the tightness. The insulating glass package can be positioned and fastened, in particular adhesively bonded, in the manufacture of the residential roof window in the casement.

This is preferably particularly easy if an outer retaining profile is provided, so that the already assembled four frame elements sash - with the outside lying down - positioned and then inserted the glass and fixed, in particular glued. Then then the Verstellfalz 12 is mounted from the inside. This procedure allows automation.

High-quality material is used in particular in the field of view for the adjustment fold 12. Otherwise, you can use Regenerat in the wing base profile, as this is not clear. The Verstellfalz 12 may be provided with thermal insulation. Preferably, it is available in different materials, in particular in the field of vision, whereby bowls are also possible to create the appropriate appearance. If initially the four frame members 4 of a sash fastened together in the corner areas and then only the glazing 6 is used, results due to the removability and adjustment of Verstellfalzes 12 a very simple installation, compared to the conventional, namely feeding the frame member 4 from the side forth to capture the disc and then connect the four frame members, is much easier.
