Description

Austrian Patent Office AT 506 611 B1 2013-12-15

The invention relates to a window frame for a window or a door of interconnected frame profiles, wherein each two frame profiles form a corner, and optionally where an outer shell in an installation position of the frame profiles an attachment shell is arranged, which is formed from Vorsatzschalenprofilen and wherein the frame profiles and / or the attachment shell profiles have or have at least one recess, and a window or a door with a sash frame and a frame.

Due to the diverse requirements of modern windows, these are subject to strict testing and standardization. In particular, the watertightness and windproofness are checked.

The increasing energy consumption means that modern residential buildings are designed as so-called Niedrigstenergiehäuser or passive houses. In many cases, these residential buildings are designed in wood frame construction with appropriate insulation both inside the wooden bolt and on the outside of the wall. In order to achieve a corresponding impermeability to rain here outside steam-permeable films are used, which prevent the ingress of water and at the same time let water pass from the inside out.

The review of driving rain safety or generally the watertightness of windows is performed on the windows themselves. As a rule, modern windows meet the corresponding standards for this purpose.

As part of a research project has now been found that the test according to the standard for the window is indeed true, but it is overlooked that prevail in the finished wall, as with inserted window, other conditions. This particular because each modern window in the frame has a circumferential groove to couple several windows together. Just this groove is but in the finished construction is a problem because the water, especially in driving rain, is no longer sufficiently dissipated forward or down, but spreads in this groove. The relative width of the insulation of the frame of windows due to heat protection measures has meant that the frame are wider than the length of the built-in sills, so that this groove ends in the wall and thus the drainage through the sill is no longer possible the transported over this groove water penetrates directly into the wall, and due to the film design can not be discharged or not in sufficient speed to the outside air. This leads to the rotting of the wall and the mold.

For the construction of windows windows in addition to the usual way polyurethane foams are used to fill the space between the wall, that is, the wall outlet for the window, and the frame. On the room side can then be arranged bridging around the frame and the foam-filled gap to increase the waterproofness and to increase the windproofness an adhesive tape. Such an adhesive tape is known for example from DE 297 15 660 U1. However, this construction can not solve the above-described problem also, since the seal takes place on the room side.

It is therefore an object of the invention to provide a window frame or a window, which remedies the above-described problem.

This object of the invention is achieved by the above-mentioned frame, wherein in the areas at least in the installation position lowermost corners on the surface of the frame profiles and / or the attachment shell profiles a recess in this area overlapping and / or filling sealing element is arranged , as well as independently through the window equipped with this frame. 1/11 Austrian Patent Office AT 506 611 B1 2013-12-15 [0009] The advantage of this solution lies in the simplicity of this measure. Namely, by this recess or groove in the corner, ie in the area of Wandeinstandes or Überdämmungsbereiches, covered by the sealing element and / or filled, although the water in the former case in this corner region in the groove penetrate, but the other Prevented penetration into the wall by the sealing element is stopped or is prevented in the embodiment with the filling of the groove with the sealing element that the water ever penetrates into this area. This cover or filling of the groove, that is the recess in the corner region of the window, is designed so wide that the water can be safely discharged to the sill for drainage. By this simple and inexpensive measure, it is therefore not necessary that the window construction and thus the corresponding production lines must be rebuilt, but the waterproofness can be achieved in the simplest case by sticking this sealing element to the appropriate places.

According to one embodiment of the invention, it is provided that the sealing element is arranged at least partially covering a formed between two frame profiles and / or header shell profiles miter, so so this sealing element not only the above-mentioned circumferential groove or provided on the underside of the frame Recesses covering, but at least partially the miter area in the corner of the window. It is thus achieved the advantage that this area of the mitered profile elements is better sealed, as this area so far was also susceptible to water ingress due to capillary. This is particularly important in attachment shells, as these shells are usually clipped only on the frame and therefore in the miter between two profile elements, a gap is formed, which may have a different size due to thermal expansion in the seasonal cycle.

Preferably, the sealing element is designed as a sealing strip, which can be done with a very simple and rapid subsequent application to the frame. In addition, a band-shaped sealing element has the advantage that it can be easily tailored to the requirements in any width, that is, at least in the width of the insulation of the window frame.

This sealing strip may be formed at least partially of an elastomer, whereby thermal stresses due to temperature differences from the sealing element can be better compensated. It is thus achieved a more durable seal. In addition, an elastomeric sealing band is better adapted to the contours of the frame, so not only can the assembly be done faster, but also the tightness can be increased.

Preferably, the elastomer is a butyl rubber or butylkautschukbasierend, since this material is self-adhesive and has on many surfaces, such as wood or wood materials, metal, especially aluminum, or plastic, a very high adhesive strength. Moreover, butyl rubber or butyl rubber-based elastomers are self-welding, that is, in the formation of folds formed when the sealing tape is three-dimensionally deformed to cover at least four sides in the corner portion of the frame, these folds have a high adhesive strength and only more with the application of a higher force, which usually leads to the destruction of the sealing strip, is solvable. It can therefore be dispensed with additional adhesive for the arrangement of the sealing strip on the surfaces of the window frame.

However, the sealing element may also be at least approximately cap-shaped, so that it must be attached essentially only to the corner region or the corner regions of the frame and sealingly connected thereto. A subsequent trimming of the sealing element or folding or the like. Can thus be omitted if necessary.

Preferably, the sealing element is formed open to vapor diffusion to obtain the breathability of the wall. For better processability and in particular for improving the contact of the sealing element in the corner region of the frame, this is preferably designed as a limp.

With limp is corresponding to the general understanding meant that so that no moments can be transmitted.

The invention further relates to the use of a band-shaped, pliable sealing element for sealing a window frame of a window or a door on an outer frame surface.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

In each case schematically simplified representation.

Fig. 1 to Fig. 4 cross sections through profile elements of conventional windows; 5 shows a detail of a window frame in end view with an inventive sealing element; Fig. 6 shows a detail of a window frame in an oblique view from below with an inventive sealing element.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals and the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis transferred to like parts with the same reference numerals or the same component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position.

Figs. 1 to 4 show a fragmentary window 1 and doors in cross section. These known from the prior art window 1 - the cross sections shown represent a variety of possible other known embodiments of windows 1 - consist of a frame 2, which is formed by frame profiles, and a sash 4, which is formed by sash profiles 5 and which carries a glass element 6.

Both the frame 2 and the sash 4 can be made of a variety of known from the prior art materials such as wood, metal, especially aluminum, plastic, especially PVC, wood plastic composite products, etc. exist.

Also, with regard to the glass element 6, the representations are not restrictive, since this glass element 6 is irrelevant to the invention. In particular, more than two glass panes can be used, as is also already known from the prior art.

In the embodiment of FIG. 1, the frame 2 and the sash frame 4 made of wood. At an outer, weathered, thus facing away from the room side, Blendrahmenoberfläche 7 and an outer casement surface 8 so-called attachment shells 9, 10, in particular made of aluminum, arranged in this embodiment, these attachment shells 9, 10, which in turn are formed from intent shell profiles 11 on suitable fastening means 12, 13 are attached, in particular clipped.

Of course, in these windows 1 and doors corresponding seals 14 are provided to achieve a corresponding water and wind tightness between the sash 4 and the frame 2.

In the embodiment according to FIG. 2, insulating elements 15, 16 are arranged between the attachment shells 9, 10 and the frame 2 or the sash frame 4 in order to increase the thermal insulation, wherein such insulation elements 15, 16 can either be glued to the window frame surface 7 , as well as with the attachment shell 9, or via appropriate attachment means 17, for example on the sash frame 4, that is to say the sash surface 8, can be arranged. These insulation elements 15, 16 are already known from the prior art.

Fig. 3 shows a variant of a window 1, wherein the frame profiles 3 and the sash profiles 5 are formed as so-called Flohlkammerprofile, with a plurality of hollow chambers 18, which optionally have a reinforcing element 19, for example a steel profile, in at least one of the hollow chambers 18 can.

Also in this variant, the arrangement of attachment shells 9, 10 is possible, as is apparent from Fig. 4. Optionally, in turn, between the attachment shells 9, 10 and the frame 2 or sash 4, the insulation elements 15, 16 are arranged according to Fig. 2.

Since these details are known in principle from the prior art, reference is made in this regard to the relevant literature.

All these variants of windows 1 and doors is common that at least one recess 21 is provided in the region of a front lower end edge 20 of the window frame 2. This recess 21 is formed in the form of a window around the circumference of the window 1 or door, such as a balcony door, circumferential groove. This groove is used to allow a coupling of a plurality of juxtaposed windows or to attach, for example, the attachment shell 9, as can be seen in FIG. 4. This recess 21 can be formed on the one hand in the attachment shell profiles 11 (FIG. 1, FIG. 2) or in the frame 2, that is in the frame profiles 3 itself (FIG. 3, FIG. 4), this being independent of the material used is, so this recess 21 is usually available in wood windows or metal windows and not only in plastic windows. Even with single windows, these recesses 21 are present, since these individual windows are not specially produced, but in principle each window is suitable for being coupled with other windows via these recesses 21.

The drainage of optionally between the frame 2 and the sash 3 incoming water is usually carried out in Figs. 1 to 4, not shown channels, so that the water, for example, by the sealing element 15 of the window frame 2 or through corresponding channels within the frame profiles 3 is derived to the outside on a windowsill. The derivation can be done both forward and sideways.

Due to the rising energy costs and environmental reasons modern residential and industrial buildings are increasingly insulated. This is also associated with the at least partial over-insulation of the frame 2, as indicated by dashed lines in Fig. 5. This over-insulation can go so far that the frame 2 is no longer visible in frontal view from the outside. For optical reasons, this means that the window sills arranged below the end edge 20 are narrower than the window frame 2 in this area, so that a corner area 22 (FIG. 5) formed by two window frame profiles 3 is no longer located above the window sill, but rather into the window sill the window 1 or the door surrounding wall protrudes. As already stated in the introduction, this is associated with the problem that, in particular in the case of heavy weathering, for example driving rain, surprisingly large quantities of water are transported within the recess 21, ie the groove, into the corner region 22 and thus run into the wall, as a result damage to this wall comes.

To avoid this problem, a sealing element 23 is provided according to the invention, as shown in FIG. 5 can be seen. This sealing element 23 is arranged on the outer frame surface 7, in particular adhesively bonded thereto. In the embodiment according to FIG. 5, the sealing element 23 is strip-shaped, the dimensions of which are such that the sealing element 23 partly has a miter area 24 between two abutting and optionally connected window frame profiles Is formed, covered and in addition, the recess 21 is arranged overlapping. Furthermore, a width 25 can be dimensioned to be maximally so large that a side edge 26 of the sealing element 23 is at least approximately flush with the later applied over-insulation.

This embodiment of the sealing element 23 represents a preferred embodiment, since it is of course possible that this sealing element 23 is arranged on the underside of the frame profiles 3, the recesses 21 overlapping, so as to prevent the escape of water from the corner 22 , With the embodiment according to FIG. 5, however, a higher watertightness is additionally achieved in the miter area 24, since it has been observed that water can occur in this miter area 24 between the window frame profiles 3 due to capillary effects. This is all the more pronounced to observe when the outer surface of the window 1 through the attachment shell 9, 10 formed as these attachment shells in the miter region 24 are not commonly connected or welded and / or sealed.

The sealing element 23 is preferably formed from an elastomer, for example EPDM or butyl rubber. In particular, the latter has the advantage that it is self-adhesive to the surfaces of the window 1, regardless of the material, so that can be dispensed with additional adhesive, although these can of course be used within the scope of the invention to the sealing member 23 with the frame surface 7 and to glue the surface of the attachment shell 9. This band-shaped sealing element 23 has a thickness in the range between 0.2 mm and 5 mm and is formed in particular limp, so that this sealing element 23 easily adapts to the contours of the surfaces on which it is arranged and thus increases the tightness. The sealing element 23 is preferably water vapor diffusion open in the outward direction, that is, in the direction of the weather side of the window 1, formed, but of course, versions with low or no vapor permeability are possible. For this purpose, on an outer surface e.g. a water vapor-impermeable layer may be arranged.

Furthermore, this sealing element 23 on its outer, that is not connected to the window frame surface 7 or the surface of the facing shell 9 surface covers or supporting means as a plaster base or for bonding the over-insulation.

This sealing element 23 is preferably stocked, in particular rolled up, stocked and optionally adapted to the respective required dimensions. It is thus no separate production of specially trained sealing elements 23, in particular with regard to the variable design of the insulation required.

Fig. 6 shows an embodiment of the invention in which the sealing element 23 extends a total of four frame surfaces 7 of two abutting frame profiles 3. Thus, not only the outwardly facing frame surface surfaces 7 are covered by this sealing element 23, but also the respectively adjoining in the region of the wall connection window frame surfaces 7. This sealing element 23 is again preferably formed of butyl rubber or butylkautschukbasierend, in particular band-shaped, here the elastomeric properties of the butyl rubber are advantageous because the sealing element 23 can be easily formed three-dimensional and thus in particular due to the adhesion of the butyl rubber any surface geometry can be covered with this sealing element 23.

Since the sealing element 23 is arranged in the corner region 22 of the frame 2, resulting in a one-piece band-shaped sealing element 23 forcibly a material projection 27. This material projection 27 is folded in a triangular shape and subsequently bent so that it with the surface of the sealing element 23rd is brought into contact. In this case, the butyl rubber proves to be advantageous because it is a kind of welding this material over-stand 27 is achieved with the remaining sealing element 23 and thus this material projection 27 with high adhesion approximately planar with the frame surface 7 in this Be 5/11 Austrian Patent Office AT506 611 B1 2013-12-15 rich - this material projection 27 can be bent both downwards and upwards - is formed. The sealing element 23 is therefore formed in the case of the embodiment of FIG. 6 at least approximately cap-shaped in the mounted state.

Of course, it is within the scope of the invention also has the possibility that the sealing element 23 is not formed in one piece, but at least two parts which are arranged overlapping each other on the frame surfaces 7, again in this case the Selbstverschweißbarkeit of butyl rubber is advantageous However, the one-piece variant is preferable because of the higher tightness.

In addition to the preferred embodiment of the sealing element 23 in strip form, in particular limp, there is the possibility, alternatively or additionally, to perform the sealing element so that it fills the recess 21 in the corner 22, wherein, if no additional sealing element 23rd in strip form, which is arranged on the outer surface of the frame profiles 3, it must be ensured that no water penetrates into this corner region 22, that is, the sealing element 23, for example, has to completely fill these recesses 21. Examples of such sealing elements may be special sealing profiles, which are designed to be closed at the front, that is to say in the direction of the window sill, and are for example profiled or cord-like and are pressed into this recess 21. Since the recesses 21 are designed quite differently with respect to their cross section, in this case specially adapted cross sections of this sealing element 23 are required for a wide variety of window types, so that this variant is significantly more costly than the preferred embodiment with the band-shaped sealing element 23, as shown in FIGS. 5 and 6 is shown.

There is also the possibility that the sealing element 23 on site, that is shortly before the installation of the window 1 in the wall, that is in the wall outlet, is generated, for example by filling the recesses 21 in the corner region 22 with silicone or a plastic foam, such as polyurethane foam, although it has been found in practice that the desired waterproofness in the corner 22 is achieved only by correspondingly high care in processing and optionally additional measures, which also these embodiments are not the preferred due to the associated higher costs are.

According to one embodiment of the invention, it has proven to be advantageous if the recess 21 or the groove, e.g. may have a cross-section of 5x5 mm, in the corner region (s) 22 first with a sealant, e.g. Silicone is at least approximately filled and then the sealing element 23 above is arranged as described above, in particular if the sealant is still wet, that is not yet fully cured or cured. It is thus achieved that at high air pressures, i. high wind speeds, the air flowing into these recesses 21 and groove is at least partially distributed over this groove over the circumference of the window and thereby entrain water. This problem can be countered with this embodiment of the invention.

To increase the adhesive strength of the sealing element 23 on the frame surface 7 of the frame profiles 3 prepaint, for example, commercially available primers, etc. may be used, although this is not required, for example, when using butyl rubber-based sealing elements 23 in ribbon form.

There is also the possibility of the cap-shaped sealing element 23 of a stiffer material, unlike the above embodiment as a band-shaped sealing element 23 has its three-dimensional shape before placement on the frame surface, form and glue it to the frame. This variant is more expensive.

The sealing element 23 may also be equipped hydrophobic.

In addition to the arrangement of four adjoining surfaces of the frame 2 or the front shell 9, as shown in Fig. 6, the sealing element can also into the area the room-side surface of the frame 2 extend.

The width 25 of the sealing element 23 (FIG. 5) on the outwardly facing window frame surface 7 is to be dimensioned so that the side edge 26 ends above the window sill to be attached or a lateral end profile of this window sill, so that the recess 21 entering into the recesses 21 Water can be removed after its return to the outside on the windowsill itself.

The embodiments show possible embodiments of the frame 2, wherein it should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but also various combinations of the individual embodiments are possible with each other and this variation possibility due to the teaching technical action by objective invention in the skill of working in this technical field expert.

For the sake of order, it should finally be pointed out that in order to better understand the structure of the window 1, this or its components have been shown partially unevenly and / or enlarged and / or reduced in size.
