Description

Die Erfindung betrifft ein Kunststofffenster mit einem Flügelprofil und einem Rahmenprofil, die jeweils als Kunststoff-Hohlkammerprofile ausgebildet sind, sowie einer am Rahmenprofil angebrachten Mitteldichtung, die aus einer steifen Halteplatte herstellt ist, auf der ein weiches Dichtungsprofil angeformt ist.The invention relates to a plastic window with a sash profile and a frame profile, each of which is designed as a plastic hollow chamber profiles, and a center seal attached to the frame profile, which is made of a rigid holding plate on which a soft sealing profile is formed.

Moderne Kunststofffenster besitzen in der Regel mehrere Dichtungsebenen zur Abdichtung des Flügelprofils gegenüber dem Rahmenprofil. Dadurch ist es möglich, höchste wärmetechnische Standards einzuhalten. Ein wichtiges Dichtungselement ist dabei die so genannte Mitteldichtung, die typischerweise im mittleren Abschnitt des Rahmenprofils, d.h. in der Fensterebene oder leicht außerhalb davon angeordnet ist. Sowohl außerhalb als auch innerhalb der Mitteldichtung können weitere Dichtungen angeordnet sein.Modern plastic windows usually have several sealing levels to seal the sash profile against the frame profile. This makes it possible to meet the highest thermal standards. An important sealing element is the so-called center seal, which is typically in the middle section of the frame profile, i.e. is located in the window plane or slightly outside of it. Additional seals can be arranged both outside and inside the center seal.

Typischerweise ist eine solche Mitteldichtung als Lippendichtung ausgebildet, um bei geringen Anpresskräften eine hohe Dichtewirkung zu erzielen. Es hat sich jedoch herausgestellt, dass mit herkömmlichen Dichtungen nicht ausreichende Dichteigenschaften erzielt werden können, ohne die zulässigen Anpresskräfte zu überschreiten.Such a center seal is typically designed as a lip seal in order to achieve a high sealing effect with low contact forces. However, it has been found that with conventional seals it is not possible to achieve sufficient sealing properties without exceeding the permissible contact forces.

Eine einschlägige Dichtungsanordnung ist aus der EP 2 363 567 A bekannt. Dabei ist an einer Halteleiste eine fahnenartige Dichtung befestigt. Die Relation zwischen der erforderlichen Anpresskraft und der Dichtwirkung ist jedoch unbefriedigend.A relevant seal arrangement is from the EP 2 363 567 A known. A flag-like seal is attached to a retaining strip. However, the relationship between the required contact pressure and the sealing effect is unsatisfactory.

Die EP 0 881 350 A beschreibt eine Türdichtung, die als Hohlprofil ausgebildet ist. Eine Anpassung einer solchen Dichtung an die Erfordernisse einer Mitteldichtung ist jedoch nicht durchgeführt.The EP 0 881 350 A describes a door seal that is designed as a hollow profile. However, such a seal has not been adapted to the requirements of a center seal.

DE 10 2008 017 325 A1 beschreibt einem Kunststoff-Fenster nach dem Oberbegriff des Anspruchs 1. DE 10 2008 017 325 A1 describes a plastic window according to the preamble of claim 1.

Aufgabe der vorliegenden Erfindung ist es, ein Kunststofffenster der oben beschriebenen Art zu weiterzubilden, dass eine verbesserte Abdichtung erreicht werden kann.The object of the present invention is to develop a plastic window of the type described above that an improved seal can be achieved.

Diese Aufgabe wird durch einem Kunststoff-Fenster nach Anspruch 1 gelöst.This object is achieved by a plastic window according to claim 1.

Der besondere Vorteil der erfindungsgemäßen Lösung besteht darin, dass die steife Halteplatte eine sichere Verankerung der Mitteldichtung in einer entsprechenden Nut ermöglicht und gleichzeitig ein besonders weiches Material für das Dichtungsprofil gewählt werden kann, so dass mit geringen Kräften eine hohe Dichtwirkung erreichbar ist.The particular advantage of the solution according to the invention is that the rigid holding plate enables the central seal to be securely anchored in a corresponding groove and, at the same time, a particularly soft material for the Sealing profile can be selected so that a high sealing effect can be achieved with low forces.

Besonders günstig ist es im Rahmen der vorliegenden Erfindung, wenn die Halteplatte aus formstabilem EPDM und das weiche Dichtungsprofil aus geschäumtem EPDM hergestellt ist, wobei Halteplatte und Dichtungsprofil vorzugsweise coextrudiert sind. EPDM bezeichnet Ethylen-Propylen-Dien-Kautschuk, ein terpolymeres Elastomer, dass an sich als Dichtungsmaterial bekannt ist. Die Kombination von unterschiedlichen EPDM-Materialien hat sich als besonders günstig herausgestellt, weil dadurch auch eine kostengünstige Herstellung der Dichtung möglich ist.In the context of the present invention, it is particularly favorable if the holding plate is made of dimensionally stable EPDM and the soft sealing profile is made of foamed EPDM, the holding plate and sealing profile preferably being coextruded. EPDM refers to ethylene-propylene-diene rubber, a terpolymeric elastomer that is known per se as a sealing material. The combination of different EPDM materials has proven to be particularly favorable because this also enables the seal to be manufactured cost-effectively.

Das weiche Dichtungsprofil weist an der der Halteplatte gegenüberliegenden Seite eine Dichtnase auf. Dabei wirkt die Dichtnase mit einer Dichtfläche zusammen, die im Wesentlichen senkrecht zur Halteplatte angeordnet ist. Insbesondere kann im Bereich der Dichtnase ein in Längsrichtung verlaufender Hohlraum im weichen Dichtungsprofil vorgesehen sein. Auf diese Weise wird ein besonders günstiges Verformungsverhalten der Dichtung erreicht.The soft sealing profile has a sealing lug on the side opposite the holding plate. The sealing lug interacts with a sealing surface which is arranged essentially perpendicular to the holding plate. In particular, a longitudinally extending cavity can be provided in the soft sealing profile in the area of the sealing nose. In this way, a particularly favorable deformation behavior of the seal is achieved.

Im Rahmen der Erfindung ist es auch möglich, dass in einem Stulpprofil eine Mitteldichtung vorgesehen ist, die aus einer steifen Halteplatte herstellt ist, auf der ein weiches Dichtungsprofil angeformt ist. Im Fall von zweiteiligen Fenstern besitzt einer der Fensterflügel typischerweise eine Stulpprofil, so dass der andere Fensterflügel an drei seiner vier Seiten an einem Rahmenprofil und an der vierten Seite am Stulpprofil anschlägt. Die erfindungsgemäße Dichtung wird daher am Stulpprofil analog zur Situation am Rahmenprofil angebracht.Within the scope of the invention, it is also possible for a face seal to be provided in a faceplate profile, which is made from a rigid holding plate on which a soft sealing profile is molded. In the case of two-part windows, one of the window sashes typically has a sash profile so that the other window sash strikes a frame profile on three of its four sides and the sash profile on the fourth side. The seal according to the invention is therefore attached to the faceplate in the same way as the situation on the frame profile.

In der Folge wird die vorliegende Erfindung anhand der in den Figuren dargestellten Ausführungsbeispiele näher erläutert. Es zeigen:

In Fig. 1 ist ein Flügelprofil 2 dargestellt, dass gegenüber einem Rahmenprofil 21 abgedichtet ist. Eine Mitteldichtung 23 ist auf einem inneren Steg 22 in einer Ausnehmung 26 befestigt. Die Mitteldichtung 23 wirkt mit einer Dichtfläche 24 am Flügelprofil 2 zusammen.In Fig. 1 A wing profile 2 is shown that is sealed against a frame profile 21. A center seal 23 is fastened on an inner web 22 in a recess 26. The center seal 23 interacts with a sealing surface 24 on the wing profile 2.

Die Mitteldichtung 23 besteht aus einer steifen Halteplatte 25, auf der ein weiches Dichtungsprofil 26 angeformt ist. Das weiche Dichtungsprofil 26 ist im Wesentlichen U-förmig ausgebildet und besitzt auf der der Halteplatte 25 gegenüberliegenden Seite eine Dichtnase 27, die seitlich vorstellt. Im Bereich der Dichtnase 27 ist ein in Längsrichtung verlaufender Hohlraum 28 vorgesehen, der die Verformung im Bereich der Dichtnase 27 zusätzlich begünstigt. Die beiden Schenkel 26a, 26b des U-förmigen Dichtungsprofils 26 sind an der Halteplatte 25 angeformt. Dabei erfolgt die Verbindung über die lateralen Drittel der Halteplatte, wobei der mittlere Bereich frei bleibt und gemeinsam mit den beiden Schenkeln 26a, 26b einen Hohlraum 26c begrenzt. Die beiden Hohlräume 28 und 26c bewirken eine besonders weiche aber gleichzeitig sichere (druckfeste) Anlage der Dichtung an der Dichtfläche.The center seal 23 consists of a rigid holding plate 25 on which a soft sealing profile 26 is formed. The soft sealing profile 26 is essentially U-shaped and has a sealing lug 27 on the side opposite the holding plate 25, which protrudes laterally. In the area of the sealing lug 27, a longitudinally extending cavity 28 is provided, which additionally promotes the deformation in the area of the sealing lug 27. The two legs 26a, 26b of the U-shaped sealing profile 26 are integrally formed on the holding plate 25. The connection is made via the lateral thirds of the holding plate, the middle region remaining free and, together with the two legs 26a, 26b, delimiting a cavity 26c. The two cavities 28 and 26c bring about a particularly soft but at the same time safe (pressure-resistant) contact of the seal on the sealing surface.

Die Halteplatte 25 ist über eine Klipsverbindung in einer Nut 29 befestigt. Diese Klipsverbindung wird bevorzugt durch ein Rastelement 25a gebildet, das an der Halteplatte 25 angeformt ist und durch Schenkel 29a, 29b gehalten wird, die die Nut 29 begrenzen.The holding plate 25 is fastened in a groove 29 via a clip connection. This clip connection is preferably formed by a latching element 25a which is integrally formed on the holding plate 25 and is held by legs 29a, 29b which delimit the groove 29.

Weitere Nuten 30 denen gegebenenfalls zur Aufnahme weiterer hier nicht dargestellter Dichtungen.Other grooves 30 which, if necessary, for receiving further seals, not shown here.

In Fig. 3 eine alternative Ausführungsvariante der vorliegenden Erfindung dargestellt. Ein erstes Flügelprofil 1 ist Teil eines nicht näher gezeigten ersten Fensterflügels. In der Fensterebene gegenüberliegend ist ein zweites Flügelprofil 2 vorgesehen, das Teil eines ebenfalls nicht näher gezeigten zweiten Fensterflügels ist. Am ersten Flügelprofil 1 ist ein Stulpprofil 3 befestigt. Die Befestigung erfolgt zumindest teilweise durch Befestigungsschrauben 4. Die Befestigungsschrauben 4 sind in einen Steg 5 eingeschraubt, der eine Hohlkammer 6 begrenzt. Diese Hohlkammer 6 ist seitlich neben und parallel zu einer weiteren Hohlkammer 7, die dazu vorgesehen ist, ein Verstärkungseisen 8 aufzunehmen. Angrenzend an die weitere Hohlkammer 7 und teilweise in diese hineinragend ist die so genannte Euro-Nut 9 angeordnet, die teilweise durch das erste Flügelprofil 1 und teilweise durch das Stulpprofil 3 begrenzt ist.In Fig. 3 an alternative embodiment of the present invention is shown. A first sash profile 1 is part of a first window sash, not shown in detail. Opposite in the window plane, a second sash profile 2 is provided, which is part of a second window sash, also not shown in detail. A faceplate 3 is fastened to the first wing profile 1. The fastening is carried out at least partially by fastening screws 4. The fastening screws 4 are screwed into a web 5 which delimits a hollow chamber 6. This hollow chamber 6 is laterally next to and parallel to another hollow chamber 7, which is intended to receive a reinforcing iron 8. Adjacent to the further hollow chamber 7 and partially projecting into it is the so-called Euro groove 9, which is partly delimited by the first wing profile 1 and partly by the faceplate profile 3.

Zusätzlich zu der Verbindung durch die Befestigungsschrauben 4 kann das Stulpprofil 3 durch nicht dargestellte Schrauben am ersten Flügelprofil 1 befestigt sein, um eine mechanisch stärker belastbare Verbindung zu gewährleisten.In addition to the connection by means of the fastening screws 4, the forend profile 3 can be fastened to the first wing profile 1 by screws, not shown, in order to ensure a mechanically stronger connection.

Das erste Flügelprofil 1 ist dazu vorgesehen, ein erstes Isolierglaselement 11 zu halten, während das zweite Flügelprofil 2 ein zweites Isolierglaselement 12 aufnimmt.The first wing profile 1 is intended to hold a first insulating glass element 11, while the second wing profile 2 accommodates a second insulating glass element 12.

Für die vorliegende Erfindung relevant ist die am Stulpprofil 3 befestigte Mitteldichtung 23, die in der oben beschriebenen Art ausgebildet ist.Relevant for the present invention is the center seal 23 attached to the faceplate 3, which is designed in the manner described above.

Fig. 4 zeigt eine Darstellung analog zu Fig. 2. Zusätzlich ist das U-förmige Dichtungsprofil 26, das aus weichem, geschäumtem EPDM hergestellt ist, mit einer Ummantelung in der Form einer Schicht 26d umgeben, die wenige Zehntel Millimeter dick ist und aus feinporigem EPDM hegestellt ist und die formstabiler ist als das weiche, geschäumte EPDM des Grundmaterials. In der Fig. 4 ist die Ummantelung 26d mit übertriebener Dicke dargestellt. Fig. 4 shows a representation similar to Fig. 2 , In addition, the U-shaped sealing profile 26, which is made of soft, foamed EPDM, is surrounded by a sheath in the form of a layer 26d, which is a few tenths of a millimeter thick and made of fine-pored EPDM and which is more dimensionally stable than the soft, foamed EPDM of the base material. In the Fig. 4 sheath 26d is shown with exaggerated thickness.

Durch die erhöhte Steifigkeit der Ummantelung 26d wird eine bessere Formbeständigkeit der Dichtung erreicht, ohne die Dichtwirkung zu beeinträchtigen und die Möglichkeit der Reinigung wird durch die feinporige Ausführung verbessert.Due to the increased rigidity of the casing 26d, a better dimensional stability of the seal is achieved without impairing the sealing effect and the possibility of cleaning is improved by the fine-pored design.
