Abstract

The frame structure comprises a frame provided with a pivotably arranged leaf frame, and interconnected frame sections. The outer frame and the sash are sealed in the closed position by several stop seals. Two adjacently arranged bump seals (25,26) are provided between an inner abutment gasket (22) and an outer rebate seal (21) such that the sealed volume between the opposing profiles (4,5) of frames (2,3) is divided into three adjacent sealed chambers (27).

Description

The invention relates to a frame construction for a window or a door, consisting of a frame and a pivotally mounted on this sash frame, each consisting of interconnected frame profiles, wherein the blend and the sash are sealed in the closed position over a plurality of stop seals to each other.

Thermal insulation in the area of a window or door is becoming increasingly important, not least because of legal regulations. While the heat insulation can be improved by mainly applied externally insulation boards on masonry, the possibilities are limited to the window or on the door. Attempts are made to improve the thermal insulation in that the individual frame profiles, which are connected to form the blind and the sash frame, are executed in plastic design as multi-chamber profiles, d. h., That they have a plurality of adjacent profile transverse direction chambers, so that the profile side over this, separate, closed air volumes are realized. Due to the separation of these individual volumes, a heat exchange with each other is made more difficult, the thermal insulation is improved on the frame side.

In order to allow in the closed position a seal against liquids, ie rain and moisture, but also to avoid air exchange between the interior and the exterior, the blend and the sash are sealed in the closed position over a plurality of stop seals to each other. Usually an inner stop and an outer stopper seal is provided, each realized via a sealing strip, such as a rubber strip, which is arranged on the blend or on the sash and sealingly abuts in the closed position on a contact surface on the respective opposite frame respectively profile part. By means of these two stop seals a volume is sealed in the closed position between the blend and the sash or the opposing frame profiles of the two frames. This volume is considerably large, since the respective opposing frame profiles of the two frames in this area are considerably spaced from each other. Viewed in the transverse direction, the volume extends to relatively narrow, volume limiting portions of the frame profiles of the sash and the wing frame, which are each made hollow. A large volume allows for a corresponding heat transfer. Since the chamber number was increased over time to improve the thermal insulation of the frame profiles, inevitably also the profile thicknesses increased, so that the volume was always larger.

The invention is therefore based on the problem of specifying a frame construction, which offers improved thermal insulation.

To solve this problem is provided according to the invention in a frame structure of the type mentioned that two adjacently disposed center stop seals are provided between an inner stop seal and an outer stop seal, such that the trapped between the opposing profiles of both frames and the inner and the outer stop seal sealed volume is divided into three adjacent sealed chambers.

According to the invention, therefore, the volume located between the two frames by means of two center stop seals in a total of three adjacent sealed chambers, thus divided so smaller volumes, which are all sealed against each other in the closed position. While the previous efforts to improve the thermal insulation focused only on the respective frame profiles themselves, the invention focuses on the sensitive area between the frame or frame profiles and realized in an advantageous manner here a multi-chamber structure by the volume of the two center stop seals in the above divided into three chambers. As a result of the sealing of the respective chambers are thus also in the Closed position given three airtight chambers, between which an air exchange and consequently a heat exchange is not possible. Thus, a significant improvement over the previously known systems thermal insulation of the frame construction is thus achieved in this area. Consequently, as seen in the transverse direction of the two frames, there are a plurality of chambers which are sealed against each other at virtually any point and consequently separate. Because the respective frame profiles themselves have, seen in the transverse direction of the profile, in each case at least four, preferably five to seven, individual chambers lying next to one another in the transverse direction. As a result of the division according to the invention also of the intermediate area via the center stop seals, at least five chambers or volumes, which are sealed off from one another, are present in this plane, namely at least one chamber on the frame, namely in the area with which the frame limits the volume located between the profiles , the three chambers formed in this volume via the two center stop seals, and a fifth chamber at the portion of the sash defining the intervening volume on the other side. If, for example, the frame side is given an additional subdivision of the local volume, so that there are two chambers lying next to one another in the transverse direction, the number of chambers in this plane even increases to six chambers.

The center stop seals, usually rubber strips with corresponding sealing lips, are expediently arranged on holding sections of the one profile and are in the closed position to abutment sections of the other profile. As holding portions, for example, along the profile running grooves, in particular on both sides undercut grooves may be provided, in which the center stop seals are used with correspondingly geometrically formed attachment portions. If necessary, if a clamp fixation does not seem sufficient, it can also be glued into it. Of course, it is also possible in principle, the center stop seals on demand directly on the frame profile surfaces stick and form on these no separate holding sections, for example in the form of grooves.

A particularly advantageous development of the invention provides to arrange the two abutment sections offset in height and either offset the two holding sections offset in height or form the two seals of different lengths. D. h., That ultimately a height offset arrangement of both the abutment sections and the seals is provided. This makes it possible with particular advantage that, for example, the leading edge of the sash when closing abutment section can be moved without touching the more forwardly arranged, him first facing center stop seal and is applied to further movement against the other rear second center stop seal, while the second, Anlageabschnitt located behind the first bearing portion, which virtually protrudes further from the tread surface, is applied against the second, then a little shorter and closer to the profile center stop seal. So it does not come to a touching or over snapping one contact portion of him ultimately not assigned center stop seal, a contact-free closing under untermittelbarer contact movement of the abutment sections of the center stop seals is possible.

The abutment sections may be formed as contact surfaces running along the profile, which are formed either on two projections projecting towards the opposite profile or on corresponding steps of the profile. Preferably, the contact surfaces are inclined to the profile plane, d. h., The projections run more or less pointed or the steps run obliquely to the profile plane. Accordingly, at an angle to the profile plane of the other profile and the center stop seals can also extend their sealing portions.

The holding portions and the abutment portions may be provided, for example, in the closed position opposite and mutually parallel surfaces of the respective frame profiles. The Frame profiles, which are relatively strong due to the Mehrkammerausgestaltung seen in the transverse direction, so may have two flat surfaces in the opposite region, which limit the volume and where the corresponding holding and abutment portions are formed protruding.

To further improve the thermal insulation in the region of the window frame can also be provided on the profiles of the frame in each case a longitudinally running chamber in which a metal profile is arranged, which consists of two U-shaped metal parts, which are connected with their legs via thermally decoupled plastic sections , Metal is a very good conductor of heat. In order to avoid that over the metal profile, which serves the stiffening of the frame, a disadvantageously effecting cold bridge is realized, it is expedient to use a two-part metal profile, comprising two U-shaped metal parts which are interconnected via the thermally decoupled plastic sections , Thus, on the one hand, the stiffening function is achieved, but on the other hand, a disadvantageous heat conduction avoided.

Further, each of the profiles of the casement each having a longitudinal chamber may be provided in which a substantially U- or G-shaped metal profile is provided, which consists of two connected via a thermally decoupling plastic section profile parts. This can also be achieved on the casement a result of the thermal decoupling not adversely affecting stiffening.

Further advantages, features and details of the invention will become apparent from the embodiment described below and with reference to the drawings. Showing:

a sectional view through an inventive frame construction of a third embodiment,

Fig. 1 shows a frame construction according to the invention 1, as it is suitable for a window or a door. It consists of a frame 2, which is anchored positionally fixed in a soffit, and a pivotally mounted on the frame sash 3. The frame 2 consists in a conventional manner of four assembled into a rectangular shape, made of plastic frame profiles 4. Likewise, the sash 3 of four assembled into a rectangular shape, made of plastic frame profiles 5. The frame profiles 4 of the frame comprise in the example shown a plurality of webs 6 separate chambers 7, wherein, seen in the transverse direction, in the embodiment shown a maximum of seven such individual chambers 7 side by side are arranged. Each chamber 7 is sealed by itself and forms an air-enclosing volume. In the large, substantially central chamber 7, a metal profile 8 is added, which serves to stiffen the frame. The metal profile 8 consists in the example shown of two U-shaped metal parts 9, which are connected at their legs via two thermally insulating plastic sections 10. Over this, the two metal parts 9 are thermally decoupled from each other, so that they ultimately form no thermal bridge.

Also visible are sometimes several chambers 7, based on the representation in Fig. 1 also arranged one above the other. At the in Fig. 1 right side of the frame 2, a hollow cheek 11 is provided, which also comprises two chambers 7. D. h., In this area vertically three chambers 7 are arranged one above the other. About this hollow cheek is a volume to be described below between the frame sections 4 of the frame and the frame profiles 5 of the sash limited and sealed.

Also, the sash 3 and its frame profiles 5 include a plurality of individual chambers 12. Again, a central large chamber 12 is provided, in which a stiffening metal section 13 is added. In the illustrated embodiment, as seen in the transverse direction, five chambers 12 are adjacent. In a section which defines a window holding strip 14, which likewise comprises two chambers 12, even six chambers are juxtaposed horizontally.

Obviously, the sash has a lateral cheek 15, which has two chambers 12 lying one above the other. This chamber also defines the volume 16 formed between the two frame profiles 4 and 5 in the closed position. The cheek 15 is located substantially opposite the cheek 11 of the window frame 2 in the transverse direction.

The volume 16 is limited on the one hand by the cheeks 11 and 14, respectively, the inner walls 17 and 18, on the other hand but also two in the closed position one above the other or adjacent to each other lying, substantially parallel to each other walls 19, 20th D. h., that consequently the volume 16 is bounded on all sides by corresponding wall sections of the respective frame profiles 4 and 5. In the area where the frame sections 4 and 5 abut each other, an outer stopper seal 21 on the frame and a Innenanschlagsdichtung 22 are provided on the casement. Both are received in corresponding clamping or locking receptacles 23, 24. These are sealing strips, preferably made of a rubber or elastomeric material. In the closed position, as in Fig. 1 shown, they lie flat and sealing on corresponding contact surfaces of the respective opposite frame profile. Thus, therefore, the volume 16 is completely sealed in the closed position.

To improve the thermal insulation, the volume 16 is further divided by two center seals 25 and 26 into a total of three separate, relatively sealed chambers 27. The chambers 27 are juxtaposed in the transverse direction. It follows that - see Fig. 1 - In the closed position a total of six chambers next to each other, namely (Starting from the right, so the frame) two chambers 7, followed by the three chambers 27, and a chamber 12 of the sash.

The two center stop seals 25, 26 are received in two holding portions 28, 29, which are each designed as both sides undercut grooves, with a corresponding latching or clamping portion. As can be seen, the holding portion 28 extends further into the volume 16 than the lower holding portion 29. This results in that the upper end of the center stopper seal 25, based on the illustration in FIG Fig. 1 , is higher than the end of the center stop gasket 26. So they are ultimately arranged offset in height.

For sealing the respective chambers 27, the center seals 25, 26 are provided on corresponding abutment sections 30, 31 which are provided at corresponding projections 32, 33 extending in the volume 16 as inclined surfaces. As Fig. 1 clearly shows, the two projections 32, 33 extend into the volume 16 to different degrees. The projection 32 extends a little less, it is associated with the center stopper seal 25, which is arranged on the other hand in the volume extending holding portion 28. The projection 33 extends further than the projection 32 into the volume, associated with it is the center stop seal 26, which is arranged on the lower holding section 29. D. h. That not only the center stop seals 25, 26 are arranged offset in height, but also the respective contact surfaces 30, 31 and the protrusions having them 32,33.

This height offset makes it possible to move the casement from the open position to the closed position and thus in abutment with all seals, without the projection 32 abuts the center stop seal 26. Rather, he is moved past this contactless. With the running into the closed position, as in Fig. 1 shown, go all seals 21, 22 and 25, 26 in the respective sealing system on the respective associated contact surface.

This results in the frame construction according to the invention a multi-chamber structure in which virtually in each transverse plane a plurality of separate chambers are given. In particular, in the transition region from the frame 2 to the sash 3, ie in the transverse plane through the volume 16, as a result of the inventive chambering of the volume 16 also there six sealed chambers realized. The volume itself is subdivided into three chambers which, since sealed, do not allow any exchange of air in the closed position, and therefore no heat transport is possible even from chamber 27 to chamber 27.

Fig. 2 shows a frame structure 1 according to the invention, the structure of the frame structure 1 from Fig. 1 equivalent. However, here the design of the frame profiles 5 of the sash 3 in relation to the realization of the contact surfaces 30, 31 slightly different than in the embodiment according to Fig. 1 , According to Fig. 2 two steps 34, 35 are provided on the profile wall 20, which virtually merge into one another and have the corresponding contact surfaces 30, 31. This step version is also hollow chambered. Due to the stepped configuration, the contact surfaces 30, 31 are also at different levels, so that when the sash frame 3 is moved relative to the frame 2, the center seal 26 does not come into contact with the contact surface 30.

Fig. 3 Finally, shows a third embodiment of a frame structure according to the invention 1. The sash corresponds in its embodiment to the Fig. 1 , only the frame 2 is executed here in the region of the profile wall 19 with respect to the configuration of the holding portions 28 differently than in the embodiment of the Fig. 1 and 2 , The two holding sections 28, 29 are here at the same height level. For the two center seals 25, 26 are different lengths. As can be seen, the center seal 25 is longer than the center seal 26, that is to say ends at a different height level than the center seal 26. It is therefore again given a stepped configuration, but realized here via seals of different lengths. Nevertheless, too a corresponding division of the volume 16 into the three chambers 27 according to the invention can be realized by way of this.

Further, here in the large chamber 12 provided on the casement U-shaped or G-shaped metal section 13 is made in two parts, consisting of two profile parts 34 and 35, which are connected by a thermally decoupled from each other plastic portion 36.

It is of course also possible to arrange the holding sections along with center seals on the sash and the contact surfaces, so projections or steps on the frame.
