Description

Die vorliegende Erfindung betrifft ein wärmegedämmtes Verbundprofil, insbesondere zur Bildung von Rahmen für Fenster, Türen, Fassadenelementen oder dergleichen, mit einem metallischen Profil auf einer ersten Seite und einem metallischen Profil auf einer gegenüberliegenden zweiten Seite, und mindestens einem Kunststoff enthaltenden Isoliersteg, der die beiden metallischen Profile unter Ausbildung einer Wärmedämmzone miteinander verbindet, wobei mindestens eine Nut zur Aufnahme eines Beschlagteiles oder Befestigungselementes vorgesehen ist.The present invention relates to a thermally insulated composite profile, in particular to form frames for windows, doors, facade elements or the like, with a metallic profile on a first side and a metallic one Profile on an opposite second side, and at least one plastic containing insulating web, which the two metallic profiles under training a thermal insulation zone connects, with at least one groove for Inclusion of a fitting part or fastener is provided.

Aus der DE 33 16 624 ist ein wärmegedämmtes Verbundprofil bekannt, das zwei Profile aus Metall aufweist, die über Isolierstäbe miteinander verbunden sind. Die Profile aus Metall weisen Nuten auf, in die Beschlagteile eingefügt werden können, sodass die Profile sich zu einem Rahmen für Fenster oder Türen zusammensetzen lassen. Zwar sorgt bei dem vorbekannten Verbundprofil die Verwendung von Isolierstegen für eine gewisse Wärmedämmung, die Isolierstege sind jedoch relativ kurz ausgebildet und schaffen daher nur eine begrenzte Wärmeisolierung. Eine Verbreiterung der Isolierstege führt zu einer Verbesserung der Wärmedämmung, führt aber auch zu einer größeren Bautiefe der Rahmenprofile selbst. Diese größere Profilbautiefe führt zu Funktionseinschränkungen der daraus gebildeten Fenster, insbesondere sind die Kleinstmaße der Fenster eingeschränkt.From DE 33 16 624 a thermally insulated composite profile is known, the two Has profiles made of metal, which are connected to one another via insulating rods. The Profiles made of metal have grooves in which fittings can be inserted, so that the profiles form a frame for windows or doors to let. With the previously known composite profile, the use of insulating webs ensures for a certain thermal insulation, but the insulating bars are relative trained short and therefore create only a limited heat insulation. A Widening of the insulating webs leads to an improvement in thermal insulation, but also leads to a greater depth of the frame profiles themselves. This greater Profile depth leads to functional restrictions of the windows formed from it, in particular, the smallest dimensions of the windows are restricted.

Es ist daher Aufgabe der vorliegenden Erfindung, ein Verbundprofil zu schaffen, das unter Beibehaltung erforderlicher mechanischer Funktionalitäten und der Profilbautiefe eine gute bzw. verbesserte Wärmedämmung besitzt.It is therefore an object of the present invention to provide a composite profile this while maintaining the required mechanical functionalities and the profile depth has good or improved thermal insulation.

Diese Aufgabe wird mit einem Verbundprofil mit den Merkmalen des Anspruches 1 gelöst.This task is accomplished with a composite profile with the features of the claim 1 solved.

Erfindungsgemäß weist das Verbundprofil eine Nut zur Aufnahme eines Beschlagteiles oder Befestigungselementes auf, deren erste Wand durch eine Außenwand oder einer Wand benachbart zu der Außenwand eines metallischen Profils und deren zweite der ersten Wand gegenüberliegende Wand an dem Isoliersteg angeformt ist. Die Nut ist somit aus einem metallischen Anteil und einem Teil am Isoliersteg gebildet, sodass die Länge des Isoliersteges vergleichsweise länger ausgebildet werden kann, was die Wärmedämmung erhöht. Die Funktionalität des Verbundprofils wird durch die Ausbildung einer solchen Nut beibehalten, da die bekannten Beschlagteile in die Nut weiter eingesetzt werden können, sodass keine mechanischen Nachteile in Kauf genommen werden müssen oder sonstige Stabilitätsprobleme auftreten. Auch die Bautiefe des Verbundprofils kann beibehalten werden.According to the invention, the composite profile has a groove for receiving a fitting part or fastener, the first wall through an outer wall or a wall adjacent to the outer wall of a metallic profile and the second wall opposite the first wall is integrally formed on the insulating web is. The groove is thus made of a metallic part and a part on the insulating web formed so that the length of the insulating web is comparatively longer can be what increases the thermal insulation. The functionality of the Composite profile is maintained by the formation of such a groove, since the known fittings can be used in the groove, so that none mechanical disadvantages have to be accepted or other stability problems occur. The depth of the composite profile can also be maintained become.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist die Nut hinterschnitten ausgebildet und sowohl an der metallischen Außenwand oder einer benachbarten Wand als auch an der zweiten Wand ist jeweils eine zur Mittelebene der Nut gerichtete hervorstehende Leiste vorgesehen. Dadurch können Beschlagteile, wie Riegelstangen in das Verbundprofil eingeschoben werden und sind gegen ein Herausfallen gesichert.According to a preferred embodiment of the invention, the groove is undercut trained and both on the metal outer wall or an adjacent Wall as well as on the second wall is one to the median plane the groove directed protruding bar provided. This allows hardware components, how locking bars are inserted into the composite profile and are against secured from falling out.

Wenn der Boden der Nut teilweise aus Isoliermaterial und teilweise aus Metall gebildet ist und die Bereiche mit unterschiedlichen Materialien im wesentlichen auf einer Ebene angeordnet sind, können die Beschlagteile besonders gut in der Nut geführt werden. Kleine Höhenänderungen am Boden können meist noch kompensiert werden, allerdings sind die Beschlagteile im Querschnitt oft symmetrisch ausgebildet, sodass die Nut vorzugsweise an den Führungsflächen ebenfalls symmetrisch ausgebildet ist.If the bottom of the groove is partly made of insulating material and partly made of metal is and the areas with different materials essentially are arranged on one level, the fittings can be particularly well in the groove be performed. Small changes in height on the ground can usually still be compensated are, however, the fittings are often symmetrical in cross section, so that the groove is also preferably symmetrical on the guide surfaces is trained.

Für eine besonders stabile Führung von Beschlagteilen ist die zweite Wand der Nut verstärkt ausgebildet. Die Verstärkung kann durch eingelagerte Fasern und/oder Inlays aus einem Verstärkungsmaterial, beispielsweise Glasfasern, Metall oder anderen Werkstoffen erfolgen. Zusätzlich oder alternativ kann die zweite Wand auf der zur ersten Wand abgewandten Seite durch eine Strebe abgestützt sein, um auch hohe mechanische Belastungen aufnehmen zu können. Wenn die Strebe schräg verläuft und mit dem Isoliersteg verbunden ist, lässt sich der Isoliersteg auch als Teil eines Hohlprofils fertigen.The second wall is the groove for a particularly stable guidance of fittings increasingly trained. The reinforcement can be by embedded fibers and / or inlays made of a reinforcing material, for example glass fibers, metal or others Materials. Additionally or alternatively, the second wall can be on the side facing away from the first wall can also be supported by a strut to be able to absorb high mechanical loads. If the strut is slanted runs and is connected to the insulating web, the insulating web can also be used as Manufacture part of a hollow profile.

Für eine Verstärkung der zweiten Wand ist es auch möglich, die zweite Wand mehrteilig auszubilden. Es können auch Verstärkungsauflagen an der Nutwand vorgesehen werden, die für eine gleichmäßige Verteilung von Kräften sorgen.To reinforce the second wall, it is also possible to use the second wall to train in several parts. There can also be reinforcement pads on the groove wall be provided, which ensure an even distribution of forces.

Gemäß einer bevorzugten Ausführungsform ist das Verbundprofil als Rahmenprofil ausgebildet und jedes metallische Profil weist mindestens eine Hohlkammer zur Einfügung eines Eckverbinders auf. Dadurch lassen sich besonders stabile Rahmen für Türen oder Fenster herstellen. In die Nut, deren Abmaße beibehalten werden können, kann dann eine Riegelstange und/oder ein anderes Beschlagteil eingefügt sein, sodass der Rahmen bei hoher Stabilität auch noch eine gute Wärmedämmung besitzt.According to a preferred embodiment, the composite profile is a frame profile formed and each metallic profile has at least one hollow chamber Insertion of a corner connector. This allows particularly stable frames for doors or windows. In the groove, the dimensions of which are retained can then insert a locking bar and / or another fitting part so that the frame also provides good thermal insulation with high stability has.

Ein Verbundprofil 1 für einen Flügelrahmen umfasst ein metallisches Profil 2 und ein metallisches Profil 3, die beispielsweise aus Aluminium extrudiert sind. Zwischen den Profilen 2 und 3 sind zwei Isolierstege 4 und 5 angeordnet, die über an sich bekannte Befestigungstechniken mit den Profilen 2 und 3 dauerhaft verbunden sind. An dem Metallprofil 3 und dem Isoliersteg 4 ist eine Nut 6 vorgesehen, wobei eine erste Wand 7 der Nut 6 durch die Außenwand des Profils 3 gebildet ist. Die Nut 6 kann auch durch eine gestrichelt dargestellte metallische Wand 16 parallel und nahe zu der Wand 7 seitlich begrenzt sein. Auf der gegenüberliegenden Seite ist eine zweite Wand 9 der Nut 6 am Isoliersteg 4 angeformt.A composite profile 1 for a casement comprises a metallic profile 2 and a metallic profile 3, which are extruded from aluminum, for example. Between the profiles 2 and 3, two insulating webs 4 and 5 are arranged, the on known fastening techniques with profiles 2 and 3 permanently connected are. A groove 6 is provided on the metal profile 3 and the insulating web 4, wherein a first wall 7 of the groove 6 is formed by the outer wall of the profile 3. The Groove 6 can also be parallel by a dashed metallic wall 16 and be limited laterally close to the wall 7. On the opposite side a second wall 9 of the groove 6 is formed on the insulating web 4.

Die Nut 6 ist hinterschnitten ausgebildet, wobei von der Außenwand 7 eine Leiste 8 und von der Wand 9 eine Leiste 10 jeweils nach innen zur Nutmitte hin hervorstehen. Durch die Leisten 8 und 10 ist ein Beschlagteil 11 unverlierbar in der Nut 6 aufgenommen, wobei die Leiste 8 gestuft ausgebildet ist und das Beschlagteil 11 nicht direkt an der Außenwand 7 verläuft. Der Boden der Nut 6 ist teilweise durch einen metallischen Abschnitt 12 des Profils 3 und teilweise durch einen Abschnitt 13 des Isoliersteges 4 gebildet, wobei durch das Einfassen eines verdickten Abschnitts 17 des Isoliersteges 4 mittels eines gerollten Steges 18 eine kleine Vertiefung in dem Boden vorgesehen ist, die jedoch die Funktionsfähigkeit der Nut 6 nicht beeinträchtigt. Je nach Bedarf kann auch der Abschnitt 13 verlängert werden und gegebenenfalls der Abschnitt 12 des metallischen Profils 3 verkürzt werden. Die Länge des Abschnitts 12 hängt bei dem gezeigten Verbundprofil 1 von der Größe der Hohlkammer 14 ab, die beispielsweise zur Aufnahme eines Eckverbinders eingesetzt wird. Auf der gegenüberliegenden Seite ist am Profil 2 ebenfalls eine Hohlkammer 15 für Befestigungsmittel vorgesehen.The groove 6 is undercut, with a bar from the outer wall 7 8 and from the wall 9 a strip 10 each protrude inwards towards the center of the groove. Due to the strips 8 and 10, a fitting part 11 is captive in the groove 6 added, the strip 8 being stepped and the fitting part 11 does not run directly on the outer wall 7. The bottom of the groove 6 is partially through a metallic section 12 of the profile 3 and partially through a section 13 of the insulating web 4 is formed, by enclosing a thickened section 17 of the insulating web 4 by means of a rolled web 18 a small depression is provided in the bottom, which, however, the functionality of the groove 6th not affected. Section 13 can also be extended as required and, if necessary, the section 12 of the metallic profile 3 can be shortened. The length of the section 12 depends on the composite profile 1 shown Size of the hollow chamber 14 from, for example, for receiving a corner connector is used. On the opposite side there is also a profile 2 Hollow chamber 15 is provided for fasteners.

In Figur 1 B ist ein vergleichbares Verbundprofil 1 nach dem Stand der Technik mit einem metallischen Profil 2' und einem metallischen Profil 3', die über Isolierstege 4' und 5' miteinander verbunden sind, gezeigt. An dem metallischen Profil 3' ist eine Nut 6' vorgesehen, deren Nutwände 7' und 9' aus Metall ausgebildet sind und die ebenfalls hinterschnitten ist, wobei nach innen hervorstehende Leisten 8' und 10' vorgesehen sind.FIG. 1B shows a comparable composite profile 1 according to the prior art with a metallic profile 2 'and a metallic profile 3', the insulating webs 4 'and 5' are interconnected.
