Description

The invention relates to a window frame for a composite window or a composite window door, with a floor frame body and a frame cover which is attached thereto to form a space therebetween, wherein the floor frame body has a plurality, each paired in a corner area interconnected floor frame members, and wherein the frame panel more Blend parts has, of which meet in each case two in a corner region of the window frame. The invention further relates to a sealing part for such a window frame according to claim 6 and a composite window according to claim 7 or a composite window door according to claim 8.

In modern window construction, composite windows or composite window doors play an essential role. In the following explanations is generally spoken of composite windows, however, in each case equally compound doors are meant. In such composite windows, the window frames are usually formed in two parts, with a floor frame body is inserted into the window reveal and serves to accommodate the static and dynamic loads, while a mounted thereon frame trim usually efficient weathering protection and / or creative freedom. Such composite windows are usually designed as a wood-aluminum composite window, the floor frame body is made of wood and the frame bezel is particularly resistant to wear due to the weather-resistant aluminum. In addition, any color scheme is possible here. However, there are also composite windows that combine other materials. It is customary to make the choice of the materials wood, metal or plastic both for the floor frame body as well as for the frame panel, wherein the same material can be used for both elements.

The frame panel is here attached via suitable holding mechanisms on the floor frame body, such. Rotary holder, rotary clip holder, locking rails or the like .. Here, between the floor frame body and the frame panel forms a free space, which consists at least in a gap, but usually contains in particular in wood-aluminum windows one or more cavities, due to the profiling of the frame panel result. This space is used for ventilation of the system, so that no moisture can accumulate here.

Due to the increasingly stringent energy saving regulations, such composite windows are increasingly used in building structures that meet high energy requirements, such as. Passive houses. These building designs take into account the realization that the window frame represents a thermal bridge in the outer skin of the building. Therefore, attempts are increasingly trying to dam with the window frame, which is usually done by additional insulation layers, which are circumferentially introduced into the window reveal and dull on the window frame. These insulating layers cover part of the outer surface of the frame panel. This is usually a layer of plaster.

A special requirement for such composite windows lies in the orderly discharge of condensation and precipitation water. This is usually done by weather protection rails and / or Ableitbleche or stone sills, which are arranged on the lower floor frame element. The impinging water is discharged here to the outside of the window and then drips usually spaced from the wall of the deflector, etc. from. Such a discharge plate, etc. extends laterally between the two window reveals, so that over the entire width of a reliable discharge of the water is possible.

However, this does not apply to moisture which condenses in the region of the lateral soffits or enters through the free space between the floor frame body and a frame panel and thus penetrates the gravity next to the weather protection rail or the deflector into the wall structure. This is particularly problematic when there are insulation materials, which in the newer construction methods increasingly the case. Their insulating effect, especially when using mineral wool or the like. Significantly suffer from this moisture. This problem exists in particular when a driving rain occurs, which is accompanied by wind, since here under the wind pressure, the rainwater is driven into the space between a side frame panel and there upright existing floor frame body.

This is from the DE 200 09 250 U1 a frame panel for a window or a door has become known, which is formed of profile rails made of metal and placed on a floor frame body made of wood. The panel parts of the frame panel abut one another here and each have a plurality of channels or cavities on the side facing the pole frame body. They are at a distance from the floor frame body to form a ventilation gap. In the region directed toward the window opening, the panel parts protrude into the region of the clear window opening, each forming an open channel. On the other hand, the cavities of the respective panel parts which are located further outward in the direction of the window reveal are sealed off by sealing profiles in such a way that the gap between the floor frame body and the frame panel is closed. In order to prevent moisture from entering the masonry below from the channel open to the window opening in the lateral panel parts, a closure plug is used here, from which moisture is removed to the lower horizontal panel.

In cooperation with the sealing profiles in the gap between the floor frame body and the frame panel, a suitable sealing effect against rainwater penetrating these open locations can thus be achieved in the normal case by means of this closure plug. However, here the area between the window reveal and the respective sealing profile remains unprotected. Should it come to an impairment or damage to the sealing profiles, so rain can get into this area behind it. Furthermore, this construction is also not suitable to dissipate condensate from the area between the window reveal and the sealing profile. Thus, moisture damage in the wall structure and possibly in particular in an insulating layer can not be prevented here.

The invention is therefore the object of developing a window frame for such a composite window or a composite window door such that any moisture damage can be reliably prevented.

This object is achieved by a window frame with the features of claim 1. This is characterized in particular by the fact that in the free space between the floor frame body and the frame panel is arranged in each case a sealing part in a corner region of the window frame, which is formed by a lower frame member in the mounting position and an adjacent side floor frame member, wherein the sealing member at least from the Corner area extends out towards the side of the floor frame element.

By the present invention, the problem was recognized in this constructive area for the first time. In order to counteract this, the invention now for the first time envisages arranging a special sealing part in this critical region and thus preventing a passage of the moisture onto the wall structure present here. This reliably prevents moisture damage in this area.

In addition, such a sealing part can be provided with relatively little effort and arranged in the structure. This is partly a retrofit of built-in window frame possible. It also benefits from the fact that the space available here is available for this purpose.

In addition, it is a further advantage that the sealing part can extend at least from the outer corner region of the frame panel in the direction away from the lateral window reveal and from the lateral floor frame element to a predetermined extent up to the area of a window sill, since this does not affect the whole, not can be sealed at the lower floor frame element or the adjacent panel part by serving as a window sill deflector etc. covered area. The intended length dimension of the sealing part is determined by the depth of the window frame in the wall structure, ie after the distance of the Over-insulation, the rain protection rail or Ableitblechs etc., from which the moisture can be dissipated ordered from the outer corner of the window frame. Thus, according to the invention a significant technological improvement can be effected on such a window frame with little design effort.

Advantageous developments of the window frame according to the invention are the subject of the dependent claims 2 to 5.

Thus, the sealing member may be formed in the shape of an angle part, the legs of which extend in the direction of the striking in the respective corner region panel parts and out of this corner. Then, a particularly reliable sealing effect can be achieved, since not only directly at the lower end of a vertical panel part entering moisture is prevented from passing into the building envelope, but also over a certain height range, a protective effect is achieved. The leg of the angular part of the sealing part extending in the direction of a vertically oriented panel part thus makes it possible to catch any rainwater driven in by wind pressure so that it is reliably prevented from entering the lateral wall area.

Furthermore, it is possible for the sealing part to have a gradient in the installed position in the direction away from a lateral floor frame element. In this way, water that has entered is reliably guided away from the corner area in the direction of the deflector plate, etc., where it can be discharged in an ordered manner. A water accumulation in this corner area is thus reliably prevented. This provides even more reliable protection against incoming moisture.

In addition, a gutter can be formed in the sealing part. Then possibly collected liquid is discharged even more targeted. In particular, it is then also more reliably possible to keep the moisture away from the floor frame body or the frame panel, which in some embodiments may also be made of wood, that is to say a material which can be affected by moisture.

Further, the sealing member may be formed as a molded part, whereby this is particularly inexpensive in large quantities available. The molded part is preferably formed as a one-piece element.

According to another aspect of the present invention according to claim 6, a sealing member for a window frame according to the invention is provided. This sealing member may be formed in the manner explained above with reference to the dependent claims 2 to 5, wherein the corresponding effects and advantages are achieved. The sealing member according to the invention is an independently tradable good, in which case it can also be used, in particular, as a retrofit component for existing composite windows.

According to yet another aspect of the present invention, according to claim 7, a composite window or according to claim 8, a composite window door is provided which have a window frame according to the invention, a window sash with glazing and a sill. Since in this case according to the invention the sealing part is arranged in the window frame, this results in a substantially improved composite window, etc., in which moisture damage can be avoided particularly reliably.

The invention will be explained in more detail in exemplary embodiments with reference to the figures of the drawing. It shows:

According to the representations in the FIGS. 1 and 2 a window assembly 1 a composite window 2, which is inserted into a window reveal 3 of a building. The composite window 2 is designed here as a wood-aluminum window.

It has a floor frame body 21, which consists of wood and is formed from a plurality of frame frames surrounding a glazing. In the FIGS. 1 and 2 In each case, a lower floor frame element 21a and a lateral floor frame element 21b are shown.

On the floor frame body 21, a frame cover 22 is placed and fastened there, which is formed from a plurality of aluminum profiles. In the FIGS. 1 and 2 a lower panel part 22a and a side panel part 22b are shown, which are mitred together.

As can be seen from this, show the FIGS. 1 and 2 Seen from the outside of the building, the left lower corner of the composite window 2. It should be noted that the right lower corner of the composite window 2, not shown, is constructed in mirror image.

The composite window 2 also has an outer window sill 23, which is designed here as an aluminum profile and serves as a deflector for rainwater. Furthermore, the composite window 2 on an inner sill 24, which is formed in the illustrated embodiment of wood.

As in particular from Fig. 1 it can be seen, the outer sill 23 is covered and plastered over the side upstands in the window reveal 3. Furthermore, the lateral panel part 22b is largely covered by the window reveal 3. This applies equally to the side panel not shown here on the other side and an upper panel part, which are also largely obscured and plastered.

Because of this installation situation of the composite window 2 in the window reveal 3, it follows that the outer window sill 23 does not extend as far as the lateral edge of the floor frame body 21, as does the respectively adjacent lateral panel part 22b. Therefore, as shown in Fig. 2 an angular sealing member 25 is provided, which is arranged in the region between the frame panel 22 and the floor frame body 21. This sealing part 25 thus seals this side area on the window frame, starting from the window reveal 3, over the window sill 23.

To illustrate this are in Fig. 2 the lower panel part 22a and the side panel part 22b omitted. In contrast, in Fig. 2 a shutter holding rail 26 can be seen, to which the lower panel portion 22a is attached. It is shown schematically by arrows P1, on which way water can penetrate especially in a driving rain occurrence in this corner region of the window frame. Due to the sealing effect of the sealing part 25, however, this water is collected there and then directed in the direction away from the window reveal 3 and the side panel part 22b toward the outer sill 23, as indicated by another arrow P2. As a result, an orderly discharge of moisture is possible.

The sealing member 25 has for this purpose a horizontal leg 25a, which is designed so that it forms a gradient in the installed state in the direction away from the lateral floor frame member 21b. The water then follows gravity and flows to the outer sill 23. The sealing member 25 further includes a vertical leg 25 b, which is a penetration of water entered in laterally Direction into the masonry etc. prevented. The length of the horizontal leg 25a is determined by the requirements of the particular application. The horizontal leg 25a is typically formed with such a length dimension that it protrudes over the window sill 23 over a certain overlap area.

In Fig. 2 Furthermore, a rotary clip holder 27 for fastening the side panel part 22b is schematically shown, as well as a floor seal 28, which cooperates to prevent rainwater from entering the free space between the side panel part 22b and the side floor frame element 21b.

In the FIGS. 3 to 6 a further embodiment of a window arrangement 1 'according to the invention is shown. A composite window 2 'shown here differs from that of the first embodiment in particular in that, instead of a deflector plate, a stone slab is used as the outer sill 23'. This is plastered in the usual way in a window reveal 3 '.

In this case, the composite window 2 'in an identical manner to the first embodiment, a floor frame body 21' with a lower floor frame member 21a 'and a side floor frame member 21b' on. Placed on top is a frame panel 22 'with a lower panel portion 22a' and a side panel portion 22b '. Also in this embodiment is in the Figures 3 and 4 only the left lower corner of the composite window 2 'viewed from the outside is shown. The other regions of the composite window 2 'are designed in an analogous manner. Here, the composite window 2 is also designed here as a wood-aluminum window.

In contrast to the first embodiment, the composite window 2 'further comprises a bank connection profile rail 29', which in a conventional manner establishes a connection connection between the lower panel part 22a 'and the window sill 23'. In addition, the composite window 2 'also contains an aperture holding profile rail 26' and rotary clip holder 27 'for fastening the panel parts and a floor seal 28'. Similarly, an inner sill 24 'made of wood is provided.

As in particular from Fig. 4 it can be seen, here also in the direction of the arrows P1 entering water in an orderly manner away from the soffit-side edge of the frame panel 22 'in the direction of the arrow P2 to the outer sill 23' derived. Again, thus by the sealing member 25 'an entry of moisture into the masonry etc. in the corner of the composite window 2' reliably avoided.

In the FIGS. 5 and 6 Sections are shown by frame parts of the window frame of the composite window 2 '. Fig. 5 shows a section through the lower horizontal frame part of the composite window 2 ', while Fig. 6 a section through a lateral, vertical frame part represents. The cuts are each set so that the sealing part 25 'is included.

As shown in Fig. 5 the lower panel part 22a 'is placed on the lower floor frame element 21a'. In order to simplify the illustration, in this case the panel-holding profile rail 26 'is just as little shown as the rotary-clip holder with which the bank connection profile rail 29' is fastened to the lower floor frame element 21a '. Out Fig. 5 It can be seen how a horizontal leg 25a 'of the sealing part 25' sealingly fills the space between the outside of the lower panel part 22a 'and the outside of the lower floor frame member 21a'. In this case, a drainage channel 25c 'is further formed in the sealing part 25', as in section in Fig. 5 is immediately apparent. The moisture collects in this gutter and, due to the gradient provided by the sealing part 25 ', is directed away from the side of the window frame towards the window sill 23'.

At the same time, the sealing member 25 'is formed so as to sealingly close the space between the lower panel part 22a' and the bank connection profile rail 29 '.

In Fig. 6 is a section through a side floor frame member 21b 'shown, which is in the example shown, the right floor frame element. On this is not shown rotary clip holder, the side panel portion 22b 'placed and thereby determined. In Fig. 6 is also a vertical leg 25b 'of the Seal member 25 'shown here produces a lateral conclusion and thus a seal to the present there reveal.

The sealing member 25 'thus extends here as in the first embodiment in the outermost corner region and by a predetermined amount along the respective soffit-side edge of the two mutually abutting diaphragm parts 22a' and 22b '.

The invention allows, in addition to the embodiment shown, further design approaches.

So it is e.g. not required in all applications that the sealing member 25 and 25 'is formed in the shape of an angle. In some applications, it may be sufficient if only the horizontal leg 25a or 25a 'is given thereof and thus a seal for wall construction under the frame panel 22 or 22' is made. This horizontal leg 25a or 25a 'thus extends here from the lateral soffit-side end of the frame panel 22 or 22' in the direction of the window sill 23 or 23 '. In this case, at the outer end of the horizontal leg instead of the vertical leg and a slightly projecting projection may be arranged so as to prevent at this point dripping collected on the horizontal leg water in the lateral wall area.

In addition, it is also not absolutely necessary to produce a gradient on the horizontal limb 25a of the sealing part 25 from the lateral soffit-side edge in the lower region of the frame panel 22 or 22 'in the direction of the sill 23. If only a very small amount of water is to be expected, the evaporation occurring in the usual way may be sufficient to remove water present on the sealing part 25.

On the other hand, it is also possible, for example, only one leg existing seal part in angular position in the corner of the composite window 2, so that there is a greater slope in the direction of the sill 23. By such an inclined position of the sealing part, a sealing effect can be achieved at the same time in the direction of the underside as well as to the side, that is to say on both outer sides of the corner area.

Furthermore, it is also not necessary that a drainage channel is formed in the sealing part.

In the illustrated embodiment, the sealing part is formed as a one-piece molded part made of an elastic plastic. However, it is also possible here to use a composite part, for example with a metal chord, whereby a greater stability and in particular dimensional stability is achieved. On the other hand, it is also possible in principle to form the sealing part on site directly in the free space between the frame panel and the floor frame body and thus to achieve a particularly reliable sealing effect. For this example, silicone can be used.

Furthermore, the window assembly 1 or 1 'may be both a normal composite window and a composite window door, i. a balcony or patio door or the like act. Even in the winter garden area, the window assembly 1 or 1 'can be used directly.

The window assembly 1 or 1 'may also be a window with fixed glazing or even a window with one or more window sashes.

Although window arrangements generally have a rectangular shape, it is also possible within the scope of the invention to deviate from this. Thus, triangular windows or window arrangements with more than four corners, with curved sections, etc., can readily be designed according to the invention.

In the present embodiments, window assembly 1 and 1 'are shown in the manner of a wood-aluminum composite window; However, according to the invention Other materials may be combined, such as a composite window with a floor frame body made of wood and a frame also made of wood. In this example, then the free space between the floor frame body and the frame is usually only slot-like, but still room for the sealing part is given. This is then only if necessary to modify or adapt accordingly in terms of its shape.
