Abstract

1. Living-room skylight with a casing (13) provided with covering frame (21) and hinged or tilting window leaf (20) attached to the casing, with window panes (2) fitted in all-round profiled seal, characterized in that both the frame of the casing (13) and the frame of the window leaf (20) comprises a weatherproof, rubber-type elastic material with an at least U, E or double T-shaped profile with all-round internal grooves, formed by the profile, into which the window panes (2) or inner rigid frame profiles (7) can be inserted, and that the panes or profiles are surrounded by the elastic casing profile (1) at least partially with a form fit and join these parts to form an inherently rigid frame structure, sealed to prevent ingress of water from the outside.

Description

The invention relates to a skylight with a window sash pivotally mounted on a feed box provided with a cover frame.

Such roof windows have been known for a long time in various embodiments. Living room skylights differ fundamentally from so-called front windows, i.e. of normal windows installed vertically in a wall in that the living room skylights in the position of use, depending on the roof pitch of the building, must be installed in a more or less inclined position. This not only results in special difficulties for the connection of the roof window to the roof skin, but also very special requirements regarding the fittings and the seal as well as the insulation against weather influences have to be taken into account constructively and when selecting the materials.

Roof windows are characterized in particular by the fact that they have at least one movable window sash that can be pivoted or folded around an axis so that the living space can be ventilated and, if necessary, the glass pane can also be cleaned from the outside.

So-called folding wings are particularly advantageous since they do not have one have interrupted sealing plane and the wing does not protrude into the interior when opening.

This means that the weight of the window sash must be relieved by appropriate construction of the fittings for opening the sash.

In addition, all external and normally not weatherproof parts of the window must be protected against the weather according to the special requirements on the roof of a building.

The usual protective measures for front windows, e.g. Paint coats or the like are only temporarily effective, i.e. they need to be renewed from time to time. However, these protective measures are not sufficient for the wooden frames of living room skylights.

One has therefore the wooden frames of living room skylights through permanent storage, such as. B. coated aluminum sheets protected. Furthermore, existing frames for living room skylights were made from aluminum profiles, which were foamed, for example, with polyurethane foam. Coated or anodized aluminum profiles are very expensive and can not prevent the wood to be protected from being destroyed by condensation water, if the wood that is stored in this way is not protected, for example, by very complex impregnation, and if heat-conducting bridges are also avoided with complex means.

The use of closed, stiffened plastic profiles Made of thermosets, PVC or similar materials is not only just as complex and therefore expensive, but also not practical because such materials are not lightfast or colorfast, are attacked by ultraviolet radiation and also because these plastic profiles do not have any on the inside have a hygroscopic effect like wood, which can have a very disadvantageous effect on kitchens and bathrooms. In addition, these frame profiles are assembled at the corners. These corner connections can never be completely sealed. In addition, existing profiles made of thermosetting plastics stiffened by metallic pipes cannot be repaired, ie once a washer has to be fitted into the associated groove with an appropriate silicone cement, it cannot be replaced if it breaks.

It follows from this that in the case of living room roof windows, very special requirements have to be made of the entire window construction, which are only partially met by the constructions known to date and not at all for roofing frames.

The object on which the invention is based is therefore to create a skylight of the type mentioned at the outset, which is fully weatherproof on the outside, is fully sealed and meets all requirements on the inside. The new living room skylight should be made in the simplest way, possibly even on site, from just a few parts and should also be easy to dismantle without difficulty, for example to replace the panes. This is achieved according to the invention in that for the modular assembly of a stable, torsionally rigid, dimensionally stable frame for windows sash and feed box a weatherproof, rubber-like elastic material, at least U- or double-T-shaped unstable jacket profile is provided, in which a solid body or inner frame profiles can be used, which are inserted at least partially positively after insertion by the elastic jacket profile and connects these parts, sealed to the outside, into a frame structure.

Although in principle any rubber-like, elastic, weather-resistant, vulcanizable material can be used for the jacket profile, it is particularly advantageous if the jacket profile consists of ethylene-propylene-tar polymer rubber (APTK).

Preferably, the arrangement is such that the legs of the U- or double-T-shaped jacket profile are designed with at least one part for a clamping effect, for example with the web form an angle of less than 90 ° and / or at their ends in Have lips shaped in the sense of a preload. The casing profile forming the frame can either be formed in one piece and glued to the abutting edges, or can be connected by vulcanization.

It is particularly advantageous if, to form a window sash, the pane can be inserted as a solid body into the jacket profile forming the frame and if the inner frame profiles can also be inserted or inserted into the jacket profile forming the frame.

It is particularly advantageous if the unstable jacket profile is an E-U profile, in which case the middle leg extending from the web comes to rest between the pane and the inner frame profiles. Preferably, the arrangement is then such that the lips or legs provided on the outer sides of the unstable U, double-T or EU-shaped jacket profile also have a prestress and are intended for receiving fittings and / or decorative strips and that upper legs of the casing profile forming the feed box and / or the lower leg of the casing profile forming the window sash are provided as sealing profiles with sealing lips. It is also expedient if the web of the jacket profile has a preferably closed cavity into which a solid profile which is stable in this direction but is flexible in the longitudinal direction of the jacket profile can be used to stiffen the web in the vertical direction.

The invention will now be explained in more detail using an exemplary embodiment in conjunction with the accompanying drawings.

• Fig. 1 eine perspektivische Teilansicht, teilweise im Schnitt, des erfindungsgemäß aufgebauten Wohnraumdachfensters;
• Fig. 2 vier mögliche Eckkonstruktionen des neuen Wohnraumdachfensters;
• Fig. 3 schematisch Einzelheiten der Befestigung von Dekorleisten und Beschlägen und
• Fig. 4 eine weitere Ausführungsform des Mantelprofils.

The figures show:

• 1 is a partial perspective view, partly in section, of the roof window constructed according to the invention;
• 2 shows four possible corner constructions of the new living room roof window;
• Fig. 3 shows schematically details of the attachment of decorative strips and fittings and
• Fig. 4 shows another embodiment of the jacket profile.

As can be seen from Fig. 1, there is shown a jacket profile 1, which consists of a weather-resistant, rubber-like elastic material. A pane 2, which can also be designed as a double pane, can be inserted into this frame profile, which can be bent in any shape to form a frame that is either closed or open on one side. It can easily be seen that only the shape of the pane determines the shape of the frame. In other words, depending on whether the disc is square, rectangular, hexagonal or round, you will get a frame that fits the outer periphery of the disc. The casing profile 1 forming the frame with the corner constructions 3, 4, 5 and 6 has an upper, inwardly directed leg 8, possibly a middle leg 9 with possibly a frame 10 and a lower leg 11, which may be on it Underside carries a sealing lip 12, which serves to seal the feed box 13.

The possible corner constructions 3, 4, 5 and 6 of the frame consisting of the casing profile 1 shown in FIG. 2 will be briefly explained. Corner 5 is simply bent by 90, for example. For this purpose, the pane 2 must of course also be rounded off at the same corner. The corner 4 is formed in that the upper leg 8 of the jacket profile visible here is cut out such that the two edges of the upper leg 8 now abut each other. It should be particularly pointed out that here only the upper one Leg 8 and of course the lower leg 11 of the jacket profile 1 are cut out, but that the web is cut in no case.

A third possibility is that the ends at corner 3 or the corners are cut off at 45 ° (at a right angle) and then after assembly either vulcanized (corner 3) or with a cyanite adhesive that sets in a matter of seconds (corner 6), which the Material of the cladding profile loosens "glued". The vulcanization takes place in the factory, the gluing can also take place "on site".

The jacket profile 1 itself thus consists of the upper leg 8, the lower leg 11 and a web 14, which is preferably connected to the middle leg 9 with the frame 10. In assembly, the jacket profile 1, which preferably consists of ethylene-propylene-tar polymer rubber, is placed in whole or in part as a ring around the disk. The corners are manufactured and connected as described. The inner frame parts 7 can be connected as a whole or in parts by fitting the lower legs 11 of the casing profile 1 or by pushing them into the casing profile 1. The inevitably resulting tensile stresses, which arise both in the longitudinal direction and in all other directions of the profile, cause the casing profile 1 to keep all parts of the wing, ie the disc 2 and the inner frame parts 7, in a sealing and insulating manner. Depending on the cross-section and / or shape of the cladding profile, compressive or tensile stresses are built up at individual points, which serve to press the upper leg 8 of the cladding profile 1 against the glass pane 2 and, if present, on one middle leg 10, which rests on the disc 2 from below, to be elastically supported and sealed at the same time. The small frame 10 at the end of the middle leg 9 serves to better nestle and hold the profile 1.

If no middle leg 9 is used, a corresponding sealing insert can be used instead, but the use of the middle leg 9 is preferred.

The lower leg 11 of the jacket profile surrounds the inner frame parts 7 from below and also has a sealing lip 12, which bears against the top of the feed box 13. The fastening of the glass pane 2 together with the inner frame parts 7, which are preferably made of wood or a wood-like material, is thus completed. It should be noted that these frame parts 7 can be removed in an equally simple manner without any tools. The same applies to disc 2.

The lips 15 and 16 arranged on the outside of the cladding profile form, together with the web 14 of the cladding profile, a U-shaped profile which serves, for example, to accommodate decorative strips, but in particular also to accommodate fittings. These decorative strips 17 can be made of any material per se and do not have to be connected to one another at the corners, since they have no sealing function. Of course, it is advantageous if these decorative strips are made of a weather-resistant and / or insulating material that is at least so stable that it clamps itself in the two lips 15, 16 drawn downwards or upwards holds. It is only essential that the decorative black cladding profile 1 can be contrasted in color by these decorative strips 17. If the decorative strips 17 are made correspondingly stable, this results in an additional stiffening effect on the jacket profile 1.

As can be seen purely schematically from FIG. 3, the casing profile 1, decorative strips 17 and / or fittings 18 can be connected to one another in a wide variety of ways. For example, the decorative strip 17 can abut the fitting 18. However, it is particularly favorable if the decorative strip has a recess on its inside corresponding to the thickness of the fitting, so that the fitting itself is hidden under the decorative strip.

On the other hand, it is also conceivable for the fitting to be guided around the entire side cheeks and at least up to a secure mounting around the underside of the window sash 20 instead of the decorative strip. This represents a possibility of getting by without special fastening means for the fitting 18. On the other hand, it is also conceivable that the clamping effect of lips 15 and 16 of correspondingly strong design is sufficient to securely connect the fitting 18 to the sash. In addition, if the fitting 18 is concealed, it can also be fastened, as indicated at 19.

The feed box 13 is constructed in a modular manner in exactly the same way as the wing 20. The lower leg 11 of the casing profile 1 with molded sealing lips 12 is used in the feed box 13 for insulation and sealing against a covering frame 21, which in this case is only used is designed as a board 23 and extends only in a single plane. In the case of the feed box, the middle leg 9 of the casing profile can either be grooved, folded over or separated. The upper leg 8 presses, as in the case of the glass pane 2, as a seal 22 onto the upper edge of the feed box and stores it against the outside world when the window is open. In addition, it serves for the elastic sealing between the wing 20 and the feed box 13 and thus makes the previously often leaky overlaps at this point unnecessary.

The outer lips 15 and 16 are also used, as in the case of the window sash 20, for receiving decorative strips and / or fittings. The hitherto customary cover frames 21 which are only more or less well sealed by overlapping are replaced here by a simple board 23 which can be plugged together from individual parts.

There are a number of advantages to this construction. Since the glass pane 2 is elastically supported, in addition to excellent insulation, there is also very good sound insulation. Due to the construction of the new roof window, lightning protection earthing is no longer required.

The whole window can basically only be assembled from three essential parts in a modular manner and just as easily dismantled again, namely from the casing profile, the pane and the inner frame part I. It has been shown that after the joining of these parts together, an extraordinary stable, torsionally rigid window that is present at all corners, and is completely tight all around. If, on the one hand, the legs or lips of the UE- or T-shaped jacket profile are directed towards one another or provided with corresponding frames, a tension is achieved, the pressure of which is sufficient to firmly connect the corresponding parts of the window to one another, although the jacket profile 1 is made of soft, pliable material. If the dimensions of the parts to be connected to one another are selected such that the pane or the inner frame parts have slightly larger dimensions than the spaces available for this purpose, which are encompassed by the legs, then a torsionally rigid, stable, stable, all-round sealed, insulated and soundproof construction protected against the weather.

4 shows a particularly advantageous embodiment of the jacket profile, in which the same parts are provided with the same reference numerals. The web 14 now has a cavity 24 which can either be closed or slotted on one long side, preferably on the inside. A profile 25 which is stiff in the vertical direction and flexible in the longitudinal direction can then either be inserted into this cavity or, if the cavity is not closed, be inserted by bending. This profile can be made of any material, but preferably aluminum.

In conclusion, it should be pointed out that the construction according to the invention is of course particularly suitable for windows of all kinds, but especially also for front windows.
