Description

Die vorliegende Erfindung betrifft einen Rahmen eines Kunststofffensters oder einer Kunststofftür, der einen aus Kunststoff-Blendrahmenprofilen gebildeten Blendrahmen, einen aus Kunststoff-Flügelrahmenprofil gebildeten Flügelrahmen und eine Mitteldichtung umfasst, die in einem Falzbereich zwischen dem Blendrahmen und dem Flügelrahmen angeordnet ist und die einen Grundkörper und eine Lippe umfasst, die an einer Anschlagfläche des Flügelrahmen unter Bildung einer umlaufenden raumseitigen Kammer und einer umlaufenden wetterseitigen Kammer anliegt.The present invention relates to a frame of a plastic window or a plastic door, which comprises a frame made of plastic frame profiles, a sash made of plastic sash profile wing frame and a center seal, which is arranged in a fold region between the frame and the sash and the base body and a lip which bears against a stop surface of the casement to form a circumferential room-side chamber and a circumferential weather-side chamber.

Die Verwendung von Mitteldichtungen im Fensterbereich ist im Stand der Technik beispielsweise aus der DE 10 2004 015 064 A1 bekannt. Darin wird eine im Falzbereich zwischen Blendrahmen und Flügelrahmen eines Fensters oder einer Tür angeordnete Mitteldichtung beschrieben, die im Querschnitt einen Aufbau mit mehreren Kammern besitzt. Eine im Aufbau analoge Mitteldichtung ist in der DE 20 2004 000 638 U1 beschrieben. Für den Einsatz in Passivhausfenstern bzw. Passivhaustüren bieten derartige Mitteldichtungen jedoch eine unzureichende Wärmeisolierung.The use of center seals in the window area is in the prior art, for example, from DE 10 2004 015 064 A1 known. This is a arranged in the rebate between the frame and sash of a window or a door center seal is described, which has a construction in cross-section with a plurality of chambers. An analogous in the construction center seal is in the DE 20 2004 000 638 U1 described. For use in passive house windows or passive doors, however, such center seals provide insufficient thermal insulation.

Darüber hinaus ist auf dem Gebiet von Fenstern und Türen aus Aluminium-Verbundprofilen bekannt, Mitteldichtungen mit zum Flügelrahmen weisenden, starren Schottleisten zu verwenden, um die Wärmestrahlung zu verringern. Mitteldichtungen mit derartigen starren Schottleisten sind in der DE 195 28 498 C1 und der DE 297 23 853 U1 bekannt. Derartige bei Aluminium-Verbundprofilen verwendete Mitteldichtungen können bei Kunststoff-Hohlprofilen nicht zum Einsatz kommen, da die zum Flügelrahmen weisende Schottleiste insbesondere bei großen Kunststofffenstern ein Öffnen und Schließen des Fensters stark behindert. Darüber hinaus bestehen derartige Mitteldichtungen aus nicht verschweißbarem Material, was bei Kunststoffprofilen zu einer erschwerten Verarbeitung führt.Moreover, in the field of aluminum composite profile windows and doors, it is known to use center seals with sash frames facing the sash to reduce thermal radiation. Center seals with such rigid barrier strips are in the DE 195 28 498 C1 and the DE 297 23 853 U1 known. Such used in aluminum composite profiles center seals can not be used in plastic hollow sections, since the sash-facing bulkhead barrier, in particular in large plastic windows greatly obstructs opening and closing of the window. In addition, such center seals made of non-weldable material, resulting in plastic profiles to a difficult processing.

Damit besteht die Aufgabe der vorliegenden Erfindung darin, einen Rahmen eines Kunststofffensters oder einer Kunststofftür mit einer Mitteldichtung zur Verfügung zu stellen, der die Nachteile des Stands der Technik überwindet. Insbesondere soll der erfindungsgemäße Rahmen des Kunststofffensters oder der Kunststofftür für eine verbesserte Wärmedämmung sorgen und einfach zu verarbeiten sein.Thus, the object of the present invention is to provide a frame of a plastic window or a plastic door with a center seal, which overcomes the disadvantages of the prior art. In particular, the inventive Frame of the plastic window or the plastic door provide for improved thermal insulation and easy to be processed.

Diese und andere Aufgaben werden mit einem Rahmen eines Kunststofffensters oder einer Kunststofftür mit den Merkmalen des Anspruchs 1. Bevorzugte Ausführungsformen des erfindungsgemäßen Rahmens sind in den davon jeweils abhängigen Ansprüchen beschrieben.These and other objects are achieved with a frame of a plastic window or a plastic door having the features of claim 1. Preferred embodiments of the frame according to the invention are described in the respective dependent claims.

Gemäß der vorliegenden Erfindung wurde überraschenderweise erkannt, dass die durch die Verwendung einer Mitteldichtung erzielte Wärmedämmung verbessert werden kann, wenn die Mitteldichtung neben der am Flügelrahmen anliegenden Lippe weiter eine zum Flügelrahmen weisende Fahne umfasst, die nicht am Flügelrahmen anliegt, wobei der Abstand zwischen Flügelrahmen und Fahne höchstens 2 mm beträgt. Ein derartiger Abstand zwischen Flügelrahmen und Fahne bietet eine ausreichende Wärmeisolierung und gewährleistet immer noch ein freies Öffnen und Schließen des Fensters bzw. der Tür. Eine derartige zum Flügelrahmen weisende Fahne sorgt einerseits für einen unter Dämmungsgesichtspunkten thermisch abgetrennten Bereich zwischen der am Flügelrahmen anliegenden Lippe und der Fahne, wodurch eine verbesserte Wärmedämmung erzielt wird, und zum anderen beinhaltet die Fahne eine gewisse Flexibilität, so dass die Fahne das Öffnen und Schließen des Kunststofffensters bzw. der Kunststofftür nicht behindert. In diesem Zusammenhang bedeutet der Begriff "thermisch abgetrennter Bereich", dass der Bereich unter dem Gesichtspunkt der Wärmeisolation so behandelt werden kann, als wäre er tatsächlich räumlich abgetrennt.According to the present invention, it has surprisingly been found that the thermal insulation achieved by the use of a center seal can be improved if the center seal next to the lip adjacent the wing frame further comprises a wing frame facing flag, which does not abut the casement, wherein the distance between casement and Flag is at most 2 mm. Such a distance between sash and flag provides sufficient heat insulation and still ensures a free opening and closing of the window or the door. Such a wing frame-facing flag on the one hand ensures a thermally separated under Dämmungsbedichtspunkte area between the lip adjacent to the casement and the flag, whereby improved thermal insulation is achieved, and on the other hand, the flag includes a degree of flexibility, so that the flag opening and closing the plastic window or the plastic door is not obstructed. In this context, the term "thermally separated area" means that the area can be treated from the viewpoint of heat insulation as if it were actually physically separated.

Dementsprechend liegt die vorliegende Erfindung in der Bereitstellung eines Rahmens eines Kunststofffensters oder einer Kunststofftür, der einen aus Kunststoff-Blendrahmenprofilen gebildeten Blendrahmen, einen aus Kunststoff-Flügelrahmenprofilen gebildeten Flügelrahmen und eine Mitteldichtung umfasst, die in einem Falzbereich zwischen dem Blendrahmen und dem Flügelrahmen angeordnet ist und die einen Grundkörper und eine Lippe umfasst, die an einer Anschlagfläche des Flügelrahmens unter Bildung einer umlaufenden raumseitigen Kammer und einer umlaufenden wetterseitigen Kammer anliegt, wobei die Mitteldichtung weiter eine von der Lippe beabstandete, zum Flügelrahmen weisende Fahne umfasst, die nicht am Flügelrahmen anliegt, und der Abstand zwischen Flügelrahmen und Fahne höchstens 2 mm beträgt.Accordingly, the present invention is to provide a frame of a plastic window or door comprising a frame formed of plastic frame profiles, a sash formed from plastic sash profiles and a center seal disposed in a rebate area between the frame and the sash and which comprises a body and a lip abutting a stop face of the sash forming a circumferential chamber and a peripheral weather-side chamber, the center seal further comprising a lip-spaced, sash-facing lug which does not abut the sash, and the distance between sash frame and flag is not more than 2 mm.

Es kann auch von Nutzen sein, wenn der Grundkörper im Querschnitt einen Aufbau aus mindestens zwei Hohlkammern aufweist. Die Hohlkammern sind dabei vorzugsweise in Richtung der Tiefe des Blendrahmenprofils angeordnet. Ein derartiger Querschnitt bewirkt eine weiter verbesserte Wärmedämmung.It may also be useful if the base body in cross-section has a construction of at least two hollow chambers. The hollow chambers are preferably arranged in the direction of the depth of the frame profile. Such a cross section causes a further improved thermal insulation.

Ebenso kann es von Vorteil sein, wenn ein thermoplastisches Polymermaterial mit einer Shore-Härte (Shore A) im Bereich von 50 Shore A bis 80 Shore A das Material der Mitteldichtung darstellt, wobei thermoplastische Polymermaterialien mit einer Shore-Härte (Shore A) im Bereich von 60 Shore A bis 80 Shore A und insbesondere im Bereich von 65 Shore A bis 75 Shore A bevorzugt sind. Ein ganz besonders bevorzugtes Material besitzt eine Härte von etwa 70 Shore A (im Bereich von 68 Shore A bis 72 Shore A). Thermoplastische Elastomere mit einer Shore-Härte in diesen Bereichen haben sich als besonders geeignet erweisen. Dabei sind thermoplastische Elastomere auf Basis von PVC, PP/EPDM sowie TPS und SBS besonders bevorzugt. Derartige Materialien ermöglichen ein Verschweißen der Mitteldichtung in den Eckbereichen der Mitteldichtung. Dabei ist es ausreichend, wenn die Lippe und die Fahne der Mitteldichtung aus einem thermoplastischen Material mit einer Shore-Härte in den genannten Bereichen hergestellt ist. Dementsprechend kann es auch günstig sein, wenn der Grundkörper der Mitteldichtung aus einem härteren thermoplastischen Material als die Lippe und Fahne hergestellt ist. Die angegeben Werte der Shore-Härte beziehen sich dabei auf die Normen DIN 53505 und DIN 7868.It may also be advantageous if a thermoplastic polymer material having a Shore A hardness in the range of 50 Shore A to 80 Shore A, the material of the center seal, wherein thermoplastic polymer materials having a Shore hardness (Shore A) in the range from 60 Shore A to 80 Shore A and especially in the range of 65 Shore A to 75 Shore A are preferred. A most preferred material has a hardness of about 70 Shore A (ranging from 68 Shore A to 72 Shore A). Thermoplastic elastomers with a Shore hardness in these ranges have proven to be particularly suitable. Thermoplastic elastomers based on PVC, PP / EPDM and TPS and SBS are particularly preferred. Such materials enable welding of the center seal in the corner regions of the center seal. It is sufficient if the lip and the flag of the center seal is made of a thermoplastic material having a Shore hardness in said areas. Accordingly, it may also be beneficial if the main body of the center seal is made of a harder thermoplastic material than the lip and flag. The specified values of the Shore hardness refer to the standards DIN 53505 and DIN 7868.

Ferner ist es besonders bevorzugt, wenn die Mitteldichtung zusammen mit dem Blendrahmenprofil in den Eckbereichen des Blendrahmens verschweißt ist. Dies ermöglicht, die Blendrahmenprofilstangen mit der Mitteldichtung fertig zu konfektionieren und bei der Verarbeitung zum Blendrahmen in den Eckbereich beide zu verschweißen.Furthermore, it is particularly preferred if the center seal is welded together with the frame profile in the corner regions of the frame. This makes it possible to make the frame profile rods ready with the center seal and to weld both in the processing to the frame in the corner area.

Ebenso kann es hilfreich sein, wenn die Mitteldichtung weiter einen Fuß umfasst, der in eine Dichtungsaufnahmenut des Blendrahmens eingezogen ist. Gleichermaßen kann es sich als günstig erweisen, wenn der Grundkörper der Mitteldichtung als eine Erhebung des Blendrahmens ausgebildet ist, wobei Lippe und Fahne an die Erhebung anextrudiert sind. Daneben kann es sich als nützlich erweisen, wenn die Mitteldichtung durch Koextrusion an den Blendrahmen anextrudiert ist. Diese Varianten der Anbindung der Mitteldichtung an das Kunststoff-Blendrahmenprofil haben sich in der Praxis als besonders nützlich gezeigt.It may also be helpful if the center seal further comprises a foot which is retracted into a seal receiving groove of the frame. Similarly, it may prove to be beneficial if the main body of the center seal is formed as a survey of the frame, lip and flag are extruded to the survey. In addition, it may prove useful if the center seal is extruded by coextrusion to the frame. These variants of the connection of the center seal to the plastic frame profile have proven to be particularly useful in practice.

Es kann vorteilhaft sein, wenn Lippe und Fahne der Mitteldichtung an derselben Seite des Grundkörpers angeordnet sind.It may be advantageous if lip and flag of the center seal are arranged on the same side of the base body.

Im Folgenden soll die vorliegende Erfindung unter Bezugnahme auf die in den Figuren dargestellten Ausführungsformen im Detail erläutert werden.In the following, the present invention will be explained in detail with reference to the embodiments shown in the figures.
