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 for the formation of frames for windows, doors, facade elements or the like, with a metallic profile on a first side and a metallic profile on an opposite second side, and at least one plastic-containing insulating web, the two metallic profiles with formation of a thermal insulation zone connects to each other, wherein at least one groove for receiving a fitting part or fastening element 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 the DE 33 16 624 is a thermally insulated composite profile is known which has two profiles made of metal, which are interconnected via insulating bars. The metal profiles have grooves into which fitting parts can be inserted so that the profiles can be assembled into a frame for windows or doors. Although provides in the known composite profile, the use of insulating bars for a certain thermal insulation, but the insulating bars are relatively short and therefore provide only a limited thermal insulation. Broadening the insulating bars leads to an improvement of the thermal insulation, but also leads to a greater depth of the frame profiles themselves. This larger profile depth leads to functional limitations of the resulting windows, in particular, the smallest dimensions of the windows are limited.

Die EP 460 514 offenbart ein Verbundprofil, das außenseitig metallische Profile aufweist, die über ein mittiges Isolierprofil verbunden sind. An dem Isolierprofil sind in einen Falzraum hervorstehende Stege ausgebildet, die als Anlage für eine Dichtung dienen. Ferner sind an den metallischen Profilen Nuten ausgebildet, in die Leisten zur Aufnahme von Beschlagsteilen eingerastet werden können.The EP 460,514 discloses a composite profile having on the outside metallic profiles which are connected via a central insulating profile. On the insulating profile projecting webs are formed in a rebate, which serve as a facility for a seal. Furthermore, grooves are formed on the metal profiles, can be engaged in the strips for receiving fitting parts.

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, which has a good or improved thermal insulation while maintaining required mechanical functionalities and the tread depth.

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

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 fastening element, whose first wall is formed by an outer wall or a wall adjacent to the outer wall of a metallic profile and the second wall of the first wall opposite to the insulating web. The groove is thus formed of a metallic portion and a part of the insulating web, so that the length of the insulating bar can be made comparatively longer, which increases the thermal insulation. The functionality of the composite profile is maintained by the formation of such a groove, since the known fitting parts can be further inserted into the groove, so that no mechanical disadvantages must be taken into account or other stability problems occur. The overall depth of the composite profile can be maintained.

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 formed and both on the metallic outer wall or an adjacent wall and on the second wall each directed towards the median plane of the groove protruding bar is provided. As a result, fitting parts, such as locking bars can be inserted into the composite profile and are secured against 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 formed partly of insulating material and partly of metal and the areas of different materials are arranged substantially on one level, the fitting parts can be guided particularly well in the groove. Small height changes on the ground can usually still be compensated, but the fitting parts are often symmetrical in cross-section, so that the groove is preferably also formed symmetrically on the guide surfaces.

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.For a particularly stable guidance of fitting parts, the second wall of the groove is formed reinforced. The reinforcement may be by embedded fibers and / or inlays of a reinforcing material, such as glass fibers, metal or other Materials are made. Additionally or alternatively, the second wall may be supported on the side facing away from the first wall by a strut in order to accommodate high mechanical loads can. If the strut is inclined and connected to the insulating bar, the insulating bar can also be manufactured as 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.For a reinforcement of the second wall, it is also possible to form the second wall in several parts. It can also be provided reinforcing supports on the groove wall, 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 designed as a frame profile and each metallic profile has at least one hollow chamber for insertion of a corner connector. This makes it possible to produce particularly stable frames for doors or windows. In the groove whose dimensions can be maintained, then a locking bar and / or another fitting part may be inserted so that the frame also has a good thermal insulation with high stability.

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.The invention will be explained in more detail below with reference to several embodiments with reference to the accompanying drawings. Show it:

FIG. 3
a cross-sectional view of a composite profile according to the invention with modified insulating strip in the assembled state.
A composite profile 1 for a wing frame comprises a metallic profile 2 and a metallic profile 3, which are extruded, for example, from aluminum. Between the profiles 2 and 3, two insulating bars 4 and 5 are arranged, which are permanently connected via known fastening techniques with the profiles 2 and 3. On the metal profile 3 and the insulating web 4, a groove 6 is provided, wherein a first wall 7 of the groove 6 is formed by the outer wall of the profile 3. The groove 6 may also be bounded laterally by a metallic wall 16 shown in dashed lines parallel and close to the wall 7. On the opposite side, a second wall 9 of the groove 6 is integrally formed on the insulating bar 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 formed undercut, wherein protruding from the outer wall 7, a bar 8 and of the wall 9, a bar 10 each inwardly toward the groove center. Through the strips 8 and 10, a fitting part 11 is captively received in the groove 6, wherein the bar 8 is stepped and the fitting part 11 is not directly on the outer wall 7. The bottom of the groove 6 is partially formed by a metallic portion 12 of the profile 3 and partly by a portion 13 of the insulating strip 4, wherein by the embedding of a thickened portion 17 of the insulating bar 4 by means of a rolled web 18, a small recess is provided in the bottom However, the functionality of the groove 6 is not affected. Depending on requirements, the section 13 can be extended and, if necessary, the section 12 of the metallic profile 3 can be shortened. The length of the portion 12 depends in the illustrated composite profile 1 on the size of the hollow chamber 14, which is used for example for receiving a corner connector. On the opposite side of the profile 2 also a hollow chamber 15 is provided for fastening means.

In Figur 1B 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.In FIG. 1B is a comparable composite profile 1 according to the prior art with a metallic profile 2 'and a metallic profile 3', which are interconnected via insulating bars 4 'and 5' shown. On the metallic profile 3 ', a groove 6' is provided, the groove walls 7 'and 9' are formed of metal and which is also undercut, wherein inwardly projecting strips 8 'and 10' are provided.

Die Länge der Isolierstege 4' und 5' beträgt lediglich A', sodass nur eine begrenzte Wärmeisolierung gegeben ist. Verglichen mit dem erfindungsgemäßen Ausfiihrungsbeispiel gemäß Figur 1A beträgt die Länge der Isolierstege 4 und 5 jeweils A und ist deutlich länger als im Stand der Technik. Dadurch wird die Wärmedämmung des Verbundprofils 1 verbessert, ohne dass dessen Breite vergrößert wird. Ferner wird die Funktionalität des Verbundprofils 1 beibehalten, da sämtliche Hohlräume 14, 15 und entsprechende Nuten 6 für den Einsatz von vorhandenen Befestigungsmitteln und Beschlagteilen genutzt werden können.The length of the insulating bars 4 'and 5' is only A ', so that only a limited heat insulation is given. Compared with the embodiment of the present invention Figure 1A the length of the insulating bars 4 and 5 is A and is significantly longer than in the prior art. As a result, the thermal insulation of the composite profile 1 is improved without its width being increased. Furthermore, the functionality of the composite profile 1 is maintained, since all cavities 14, 15 and corresponding grooves 6 can be used for the use of existing fasteners and fittings.

In Figur 2 ist ein Isolierprofil 40 aus Kunststoff oder einem Verbundwerkstoff gezeigt, das bei einem erfindungsgemäßen Verbundprofil eingesetzt werden kann. Das Isolierprofil 40 umfasst einen Isoliersteg 41 an dem endseitig jeweils Verdickungen 42 und 43 ausgebildet sind, die an Stegen eines Metallprofils für eine Dauerhafte Verbindung eingefasst werden können. Ferner sind an den Verdickungen 42 und 43 jeweils Rändeldrähte 44 vorgesehen, die die Schubfestigkeit zwischen Isoliersteg 41 und dem jeweiligen metallischen Außenprofil durch Formschluss verbessern.In FIG. 2 an insulating profile 40 made of plastic or a composite material is shown, which can be used in a composite profile according to the invention. The insulating profile 40 comprises an insulating web 41 on the end of each thickenings 42 and 43 are formed, which can be bordered on webs of a metal profile for a permanent connection. Furthermore, knurling wires 44 are provided on the thickenings 42 and 43, respectively, which improve the shear strength between the insulating web 41 and the respective metallic outer profile by positive locking.

An dem Isolierprofil 40 ist ein Nutboden 45 und eine sich winklig dazu erstreckende Nutwand 46 ausgebildet, die am oberen Ende eine nach innen zu einer Nutmitte hin gerichtete Leiste 47 umfasst. Die Nutwand 46 und die Leiste 47 sind durch eine auf der der Nut abgewandten Seite erstreckende Strebe 48 abgestützt, sodass durch die Nutwand 46 auch erhöhte mechanische Belastungen aufgenommen werden können. An der Strebe 48 ist ferner noch eine Leiste 49 als Anlage für eine Dichtung angeformt.On the insulating profile 40, a groove bottom 45 and an angle thereto extending groove wall 46 is formed, which comprises at the upper end a directed inwardly toward a Nutmitte bar 47. The groove wall 46 and the strip 47 are supported by a strut 48 extending on the side facing away from the groove, so that increased mechanical loads can also be absorbed by the groove wall 46. On the strut 48 is still a bar 49 is formed as an attachment for a seal.

In Figur 3 ist ein erfindungsgemäßes Verbundprofil im montierten Zustand gezeigt. Ein metallisches Profil 2 ist über ein Isolierprofil mit einem Isoliersteg 41' und einem Isoliersteg 5 mit einem weiteren metallischen Profil 3 verbunden. Das Verbundprofil ist Bestandteil eines Rahmens eines Flügels, in dem eine Isolierglasscheibe 55 eingefasst ist. Ferner ist eine Nut 6 vorgesehen, die wie bei den vorangegangenen Ausführungsbeispielen eine Wand aufweist, die durch die Außenwand des metallischen Profils 3 gebildet ist und an der gegenüberliegenden Seite eine Wand aufweist, die an dem Isolierprofil angeformt ist. Die Wand ist auf der Seite des Isolierprofils mehrteilig ausgebildet und umfasst einen Halteabschnitt 46' aus dem Material des Isolierprofils und eine Einlage 51, die an dem Isolierprofil eingefasst ist. An der Einlage 51 ist eine nach innen hervorstehende Leiste 52 ausgebildet, sodass ein Beschlagteil unverlierbar in die Nut 6 einschiebbar ist. Die Wand 46' ist über eine Strebe 48' abgestützt, die mit dem Isoliersteg 41' verbunden ist. An der Strebe 48' ist ein Anschlag 49' für eine Dichtung 50 angeformt.In FIG. 3 an inventive composite profile is shown in the mounted state. A metallic profile 2 is connected via an insulating profile with an insulating web 41 'and an insulating web 5 with a further metallic profile 3. The composite profile is part of a frame of a wing, in which an insulating glass pane 55 is enclosed. Further, a groove 6 is provided, which has a wall, as in the previous embodiments, which is formed by the outer wall of the metallic profile 3 and on the opposite side has a wall which is integrally formed on the insulating profile. The wall is on the side of the insulating profile formed in several parts and comprises a holding portion 46 'of the material of the insulating profile and an insert 51 which is bordered on the insulating profile. On the insert 51 an inwardly projecting bar 52 is formed, so that a fitting part is captively inserted into the groove 6. The wall 46 'is supported by a strut 48' which is connected to the insulating web 41 '. On the strut 48 ', a stop 49' for a seal 50 is formed.

Bei dem gezeigten Ausführungsbeispiel ist der Blendrahmen gemäß dem Stand der Technik mit einem metallischen Profil 22' und einem metallischen Profil 23', die über Isolierstege 24' und 25' verbunden sind, ausgebildet. Es ist auch möglich, auch für den Blendrahmen ein erfindungsgemäßes Verbundprofil einzusetzen.In the embodiment shown, the frame according to the prior art with a metallic profile 22 'and a metallic profile 23', which are connected via insulating bars 24 'and 25', formed. It is also possible to use an inventive composite profile for the frame.

Bei den gezeigten Ausführungsbeispielen ist die Größe der Hohlräume bei den Metallprofilen meist von den Stabilitätsanforderungen und der vorgesehenen Befestigungsmittel, wie Eckverbinder, abhängig. Dadurch ist der Bereich des Nutbodens, der durch den Isoliersteg gebildet ist, relativ klein. Es ist auch möglich, die Isolierstege bei anderen mechanischen Bedingungen zu verlängern. Die Nutabmaße und die Bautiefe des Profils können jedoch beibehalten werden.In the embodiments shown, the size of the cavities in the metal profiles usually depends on the stability requirements and the intended fastening means, such as corner connectors. As a result, the region of the groove bottom, which is formed by the insulating web, is relatively small. It is also possible to extend the Isolierstege under other mechanical conditions. However, the groove dimensions and the depth of the profile can be maintained.

Die Isolierstege bestehen aus einem Kunststoffmaterial, das durch Glasfasern oder andere Materialien verstärkt werden kann. Ferner ist es möglich, statt der Einlage 51 eine Einlage in Form von Glasfaser-Inlays in das Isolierprofil ein- oder anzuformen oder andere weitere Verstärkungsmittel vorzusehen.The insulating bars are made of a plastic material that can be reinforced by glass fibers or other materials. It is also possible, instead of the insert 51, to insert or form an insert in the form of glass fiber inlays into the insulating profile or to provide other further reinforcing means.
