Description

Die Erfindung bezieht sich auf ein wärmedämmendes Verbundprofil, insbesondere für Fenster- oder Türrahmen, mit den im Oberbegriff des Patentanspruchs 1 angegebenen Merkmalen.The invention relates to a heat-insulating composite profile, in particular for window or door frames, with the features specified in the preamble of claim 1.

Es ist ein wärmedämmendes Verbundprofil dieser Art bekannt (DE-A-2 911 832), bei dem die lsolierleiste im unteren Bereich durch entsprechende Zwangsführungen an den jeweiligen Metallprofilstäben gehalten wird.A heat-insulating composite profile of this type is known (DE-A-2 911 832), in which the insulating strip is held in the lower area by corresponding positive guides on the respective metal profile bars.

Die nach der DE-A-2 911 832 bekannte Konstruktion hat den Nachteil, daß die Zwischenstege und die durchgehenden Leisten hinsichtlich ihrer Anlage an der Isolierleiste in der Praxis überbestimmt sind. Durch Toleranzen der Metallprofilstege wie auch der Isolierleiste ergibt sich, daß entweder die Zwischenstege oder die Metalleisten zur Anlage an der Isolierleiste kommen. Durch das Anformen der Metalleisten, an die Isolierleiste ergibt sich in dem Fall der Anlage der Metalleisten an der Isolierleiste ein Zwang innerhalb der Isolierleiste, die sich so lange verformt, bis auch die Zwischenstege anliegen. Diese Verformung kann naturgemäß an den beiden Profilseiten unterschiedlich sein, so daß diese Verformung zu Ungenauigkeiten im Verbundprofil führt, wodurch die Toleranzen des Gesamtprofiles beeinflußt werden. Sofern lediglich die Zwischenstege an der lsolierleiste anliegen, ergibt sich zwischen den Metalleisten und den zugeordneten Nuten der Isolierleiste ein Spiel, das dafür sorgt, daß die Isolierleiste in diesem Bereich nicht an der Innenfläche der Metallprofilstäbe anliegt. Hierdurch wird die Planparallelität der beiden Metallprofilstäbe beeinflußt. Die Metailprofilstäbe pendeln um die obere Einspannstelle der Isolierleiste, die aus den Metallstegen und den Zwischenstegen gebildet wird. Da an der den Zwischenstegen abgewandten Seite es in diesem Fall nicht zu einer kraftschlüssigen Verbindung zwischen der Isolierleiste und den Metallprofilstäben kommt, ist auch eine einwandfreie Kraftabtragung über den Verbundbereich nicht mehr möglich.The construction known from DE-A-2 911 832 has the disadvantage that the intermediate webs and the continuous strips are overdetermined in practice with regard to their contact with the insulating strip. The tolerances of the metal profile webs and the insulating strip mean that either the intermediate webs or the metal strips come into contact with the insulating strip. The molding of the metal strips on the insulating strip results in a constraint within the insulating strip in the case of the metal strips being in contact with the insulating strip, which deforms until the intermediate webs also abut. This deformation can of course be different on the two profile sides, so that this deformation leads to inaccuracies in the composite profile, which affects the tolerances of the overall profile. If only the intermediate webs abut the insulating strip, there is a play between the metal strips and the associated grooves of the insulating strip, which ensures that the insulating strip does not abut the inner surface of the metal profile rods in this area. This affects the plane parallelism of the two metal profile bars. The metal profile bars swing around the upper clamping point of the insulating strip, which is formed from the metal bars and the intermediate bars. Since, in this case, there is no non-positive connection between the insulating strip and the metal profile bars on the side facing away from the intermediate webs, it is no longer possible to transfer force perfectly via the bonded area.

Ausgehend von dem erörterten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein wärmedämmendes Verbundprofil der im Oberbegriff des Patentanspruchs 1 genannten Art so zu gestalten, daß eine genaue Lagestabilität der Metallprofilstäbe und der Isolierleiste trotz der Fertigungstoleranzen und Fertigungsungenauigkeiten der den Verbund bildenden Bauteile gewährleistet ist.Based on the prior art discussed, the invention has for its object to design a heat-insulating composite profile of the type mentioned in the preamble of claim 1 so that an accurate positional stability of the metal profile bars and the insulating strip is ensured despite the manufacturing tolerances and manufacturing inaccuracies of the components forming the composite .

Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teils des neuen Patentanspruches 1 gelöst.This object is achieved by the features of the characterizing part of the new patent claim 1.

Durch die in diesem Anspruch herausgestellten Maßnahmen ist gewährleistet, daß alle Randleisten mit ihren seitlichen Begrenzungsflächen kraftschlüssig an der Innenwand der Metallprofilstäbe zur Anlage kommen. Hierbei ist der Spalt zwischen dem Nutboden der Aufnahmenut und der Randleiste sehr wichtig, dadurch diesen Spalt in jedem Fall eine Anlage der Randleisten an den Zwischenstegen gewährleistet ist und die Randleisten durch eine bei der Verschwenkung und Kaltverformung des lnnenstegs, auftretende Kraft an die Innenfläche des Metallprofilstabs gepreßt werden.The measures highlighted in this claim ensure that all the edge strips come with their lateral boundary surfaces to the non-positively against the inner wall of the metal profile bars. Here, the gap between the groove bottom of the receiving groove and the edge strip is very important, as this gap ensures that the edge strips are in contact with the intermediate webs in each case, and the edge strips are caused by a force that occurs during the pivoting and cold deformation of the inner web against the inner surface of the metal profile rod be pressed.

Die ferner zum Stand der Technik gennante US-A-3 517 472 zeigt und beschreibt Verbundprofile, die nicht unter den Gattungsbegriff des Patentanspruches 1 fallen, da diese Verbundprofile keine Zwischenstege aufweisen, die in entsprechende Nuten der lsolierleiste eingreifen. Beim Gegenstand der US-A-3 517 472 nach den Fig. 6 und 7 wird die Isolierleiste ausschließlich durch die beidseitig anzuformenden Metallstege gehalten. Die Maßhaltigkeit des gesamten Verbundprofils ist von den Toleranzen der Isolierleiste und den Toleranzen der Aufnahmenuten der Metallprofile abhängig. Hinzu kommt eine Kompressibilität der Isolierleiste, die ebenfalls die Abmaße des Verbundprofils beeinflußt. Je stärker ein Metallsteg angeformt wird, umso stärker fließt das Material der Isolierleiste in diesem Bereich. Bei ungleich starken Anformungen der Metallstege ergeben sich Versetzungen der Metallprofile zueinander.The further known to the prior art US-A-3 517 472 shows and describes composite profiles that do not fall under the preamble of claim 1, since these composite profiles have no intermediate webs that engage in corresponding grooves of the insulating strip. In the subject of US-A-3 517 472 according to FIGS. 6 and 7, the insulating strip is held only by the metal webs to be molded on both sides. The dimensional accuracy of the entire composite profile depends on the tolerances of the insulating strip and the tolerances of the grooves in the metal profiles. In addition, there is a compressibility of the insulating strip, which also influences the dimensions of the composite profile. The more a metal bar is molded, the more the material of the insulating strip flows in this area. If the metal webs are shaped differently, the metal profiles will dislocate.

Bei einer vorteilhaften Ausführungsform der Erfindung weist die Isolierleiste in allen Eckbereichen Randleisten auf, die mit ihren seitlichen Begrenzungsflächen kraftschlüssig an der Innenwandung der Metallprofilstäbe anliegen.In an advantageous embodiment of the invention, the insulating strip has edge strips in all corner regions, which, with their lateral boundary surfaces, bear non-positively on the inner wall of the metal profile bars.

In den vier Eckbereichen der Isolierleiste ergibt sich somit eine sichere, Fertigungstoleranzen und Fertigungsungenauigkeiten der den Verbund bildenden Bauteile überbrückende Verspannung zwischen der Isolierleiste und den Metallprofilstäben.In the four corner areas of the insulating strip, there is thus a safe, manufacturing tolerances and manufacturing inaccuracies of the bracing bridging components between the insulating strip and the metal profile bars.

Die vertikale Verspannung zwischen den Metallprofilstäben und der lsolierleiste erfolgt ebenfalls aufgrund der nicht verformbaren Zwischenstege, die in Nuten der Isolierleiste eingreifen, und der verformbaren durchgehenden Leisten der Metallprofilstäbe. Da nur die an der Innenseite der Metallprofilstäbe vorgesehen durchgehenden Leisten verformt werden, werden die Sichtflächen der Metallprofilstäbe parallel zueinander gehalten. Auch ein Versatz in der Höhe wird unterbunden.The vertical bracing between the metal profile bars and the insulating strip also takes place on account of the non-deformable intermediate webs which engage in grooves in the insulating bar and the deformable continuous strips of the metal profile bars. Since only the continuous strips provided on the inside of the metal profile bars are deformed, the visible surfaces of the metal profile bars are kept parallel to one another. An offset in height is also prevented.

Zur Erhöhung der Isolierwirkung bei Aufrechterhaltung einer hohen Stabilität der Isolierleiste sind zweckmäßigerweise innerhalb der Isolierleiste zwei oder vier als Luftkammern dienende Hohlräume vorgesehen.To increase the insulating effect while maintaining a high stability of the insulating strip, two or four cavities serving as air chambers are expediently provided within the insulating strip.

Somit wird eine feste Verbindung zwischen der lsolierleiste und Metallprofilstäben unter Einhaltung einer genauen Gesamtprofiltiefe hergestellt. Die das Verbundprofil bildenden Bauteile werden miteinander in vertikaler als auch in horizontaler Richtung verspannt, wobei durch das anfänglich vorhandene Spiel zwischen den Bauteilen auch größere Fertigungstoleranzen ohne weiteres ausgeglichen werden.This creates a firm connection between the insulating strip and metal profile bars while maintaining an exact overall profile depth. The components forming the composite profile are clamped to one another in the vertical as well as in the horizontal direction, with larger manufacturing tolerances being easily compensated for by the initially existing play between the components.

Ausführungsbeispiele des erfindungsgemäßen Verbundprofils sind in den Zeichnungen dargestellt und werden im folgenden beschrieben.Exemplary embodiments of the composite profile according to the invention are shown in the drawings and are described below.

Das Verbundprofil setzt sich aus Metallprofilstäben 1, 2 ; 1a, 2a und einer profilierten, formbeständigen, aus Kunststoff bestehenden Isolierleiste 3 zusammen. Die Isolierleiste bei dem Ausführungsbeispiel nach den Fig. 1 und 2 weist vier als Luftkammern ausgebildete Hohlräume 4 auf, wobei die Stege zwischen den Hohlräumen 4 als Diagonalen 5 der Isolierleiste 3 ausgebildet sind.The composite profile consists of metal profile bars 1, 2; 1a, 2a and a profiled, dimensionally stable, plastic insulating strip 3 together. The insulating strip in the exemplary embodiment according to FIGS. 1 and 2 has four cavities 4 designed as air chambers, the webs between the cavities 4 being designed as diagonals 5 of the insulating strip 3.

Bei dem Ausführungsbeispiel nach der Fig. 4 ist die Isolierleiste 3 mit zwei Hohlräumen 4 ausgestattet.In the embodiment according to FIG. 4, the insulating strip 3 is equipped with two cavities 4.

An den Profilstäben 1, 2,1a, 2a sind im oberen Bereich außerhalb der sie verbindenden Isolierleiste 3 gegenüberliegende, im Ausgangszustand waagerecht liegende, durchgehende Leisten 6, 7, an deren Unterseite jeweils ein durchgehender Nocken 8 angeordnet ist. Dem Nocken 8 ist eine entsprechende Vertiefung 9 in der Isolierleiste 3 zugeordnet. Außerdem weist die Isolierleiste 3 an ihren den Metallprofilstäben 1, 2 zugewandten Seiten jeweils eine schräg nach oben in das Innere derselben gerichtete Nut 10, 11 auf. In diese Nuten greifen Zwischenstege 12, 13 der Metallprofilstäbe. Die lichte Weite der schrägen Nuten 10, 11 ist wesentlich größer als die Stärke der Zwischenstege 12, 13. Jeder Zwischensteg 12, 13 besitzt an seiner Übergangsstelle zum zugehörigen Metallprofilstab 1, 2, 1a, 2a eine durchgehende Rille 14, in die eine Randleiste 15 der Isolierleiste 3 mit ihrer Spitze eingreift. Des weiteren weist die Isolierleiste 3 mittig an ihrer Unterseite eine Nase 16 auf, die beim Einsatz des Verbundprofils als Fensterflügel für den entsprechenden Blendrahmen als Anschlag dient.On the profile bars 1, 2, 1a, 2a, in the upper area outside the insulating strip 3 connecting them, opposite, in the initial state, horizontal, continuous strips 6, 7, on the underside of which a continuous cam 8 is arranged. A corresponding recess 9 in the insulating strip 3 is assigned to the cam 8. In addition, the insulating strip 3 has on its sides facing the metal profile bars 1, 2 in each case an obliquely upward groove 10, 11 directed into the interior thereof. Intermediate webs 12, 13 of the metal profile bars engage in these grooves. The clear width of the oblique grooves 10, 11 is substantially greater than the thickness of the intermediate webs 12, 13. Each intermediate web 12, 13 has a continuous groove 14 at its transition point to the associated metal profile bar 1, 2, 1a, 2a, into which an edge strip 15 the insulating strip 3 engages with its tip. Furthermore, the insulating strip 3 has a nose 16 in the center on its underside, which serves as a stop when the composite profile is used as a window sash for the corresponding frame.

Bei dem Ausführungsbeispiel nach den Fig. 1 und 2 ist an jedem Metallprofilstab 1, 2 eine untere, den oberen Leisten 6, 7 gegenüberliegende hakenförmige Leiste 17, 18 angebracht. Jede Leiste 17, 18 greift bereits im ungespannten Zustand, der in der Fig. 1 dargestellt ist, in eine entsprechende Nut 19 der Isolierleiste 3 ein. Der Steg 20 der Leiste 17, 18 ist unter einem Winkel von ca. 10° gegenüber der Querebene 21 zum Metallprofilstab nach unten geneigt, während der Winkel zwischen der Innenseite des Hakens 22 der Leiste 17, 18 und der Parallelebene 23 zum Metallprofilstab ca. 20° beträgt. Dementsprechend beträgt auch der Winkel zwischen den Seitenwänden der Nut 19 und der Parallelebene 23 ca. 20°. Hierbei ist sowohl der Übergang von der Innenseite des Hakens 22 der Leiste 17,18 zu der Innenseite des Steges 20 der Leiste 17, 18 als auch der Übergang von der dem zugehörigen Metallprofilstab nächstliegenden Seitenwand der Nut 19 zu der Unterseite der Isolierleiste 3 hin abgerundet ausgebildet. Ebenfalls abgerundet ausgeführt sind die Übergänge vom Boden der Nut zu ihren Seitenwänden. Außerdem weist der Übergang von der Oberseite des Hakens 22 der Leiste 17, 18 zu seiner Rückseite hin eine Abrundung auf. Schließlich ist auch der Übergang von der Außenseite des Steges 20 der Leiste 17, 18 zu dem zugehörigen Profilstab abgerundet ausgebildet. Die Stärke des Hakens 22 der Leiste 17, 18 entspricht der Stärke des Steges 20 der Leiste 17, 18. In die Innenseite des Steges 20 der Leiste 17, 18 ist an der Verbindungsstelle mit dem zugehörigen Metallprofilstab eine durchgehende Rille 24 als Sollbiegestelle eingelassen. Das in die Seitenwand der Nut 19 eingreifende Ende des Hakens 22 der Leiste 17, 18 ist spitz ausgeführt.In the embodiment according to FIGS. 1 and 2, a lower hook-shaped bar 17, 18 is attached to each metal profile bar 1, 2, opposite the upper bars 6, 7. Each strip 17, 18 already engages in a corresponding groove 19 of the insulating strip 3 in the untensioned state, which is shown in FIG. 1. The web 20 of the bar 17, 18 is inclined at an angle of approximately 10 ° relative to the transverse plane 21 to the metal profile bar, while the angle between the inside of the hook 22 of the bar 17, 18 and the parallel plane 23 to the metal profile bar is approximately 20 ° is. Accordingly, the angle between the side walls of the groove 19 and the parallel plane 23 is approximately 20 °. Both the transition from the inside of the hook 22 of the strip 17, 18 to the inside of the web 20 of the strip 17, 18 and the transition from the side wall of the groove 19 closest to the associated metal profile rod to the underside of the insulating strip 3 are rounded off . The transitions from the bottom of the groove to its side walls are also rounded. In addition, the transition from the top of the hook 22 of the strip 17, 18 to its back has a rounding. Finally, the transition from the outside of the web 20 of the strip 17, 18 to the associated profile rod is rounded. The thickness of the hook 22 of the bar 17, 18 corresponds to the thickness of the web 20 of the bar 17, 18. In the inside of the web 20 of the bar 17, 18 a continuous groove 24 is embedded as a predetermined bending point at the connection point with the associated metal profile bar. The end of the hook 22 of the bar 17, 18 engaging in the side wall of the groove 19 is pointed.

Bei der Herstellung des Verbundprofils nach den Fig. 1 und 2 werden gleichzeitig oder zeitlich versetzt zueinander einerseits die oberen Leisten 6, 7 aus ihrer waagerechten, in der Fig. 1 aufgezeigten Lage nach unten gedrückt, so daß die Nocken 8 mit den Vertiefungen 9 in der Isolierleiste 3 in Eingriff kommen und andererseits die unteren hakenförmigen Leisten 17, 18 aus ihrer schräg nach unten gerichteten Lage in eine annähernd waagerechte Lage hochgedrückt werden, wodurch die Haken 22 der Leisten 17, 18 die Isolierleiste fest an die entsprechende Innenwand 26 der Metallprofilstäbe 1, 2 anpressen.1 and 2, the upper ledges 6, 7 are pressed downward from their horizontal position shown in FIG. 1, so that the cams 8 with the depressions 9 in the insulating strip 3 come into engagement and, on the other hand, the lower hook-shaped strips 17, 18 are pushed up from their obliquely downward position into an approximately horizontal position, whereby the hooks 22 of the strips 17, 18 firmly attach the insulating strip to the corresponding inner wall 26 of the metal profile bars 1 , Press on 2.

Bei der Verformung der Leisten 6, 7 aus der in der Fig. 1 aufgezeigten Lage in die Stellung nach der Fig. 2 erfolgt eine Verschwenkung der Leisten 6, 7 um Achsen A. Die Verschwenkung der hakenförmigen Leisten 17, 18 erfolgt um Achsen B. Die Randleisten 15, 25 der Isolierleiste 3 werden in der in der Fig. 2 aufgezeigten Endstellung mit ihren seitlichen Begrenzungsflächen 15a, 25a kraftschlüssig an der Innenwand 26 der Metallprofilstäbe festgelegt.When the strips 6, 7 are deformed from the position shown in FIG. 1 into the position according to FIG. 2, the strips 6, 7 are pivoted about axes A. The hook-shaped strips 17, 18 are pivoted about axes B. In the end position shown in FIG. 2, the edge strips 15, 25 of the insulating strip 3 are non-positively fixed to the inner wall 26 of the metal profile bars with their lateral boundary surfaces 15a, 25a.

Durch die Verdrehung der Leisten 6, 7 wird die Isolierleiste 3 auch fest auf die Zwischenstege 12, 13 gedrückt, so daß sich neben dem Kraftschluß auch ein Formschluß ergibt und eine dauerhafte, unveränderbare Verbindung der einzelnen, den Verbund bildenden Bauteile erzielt wird.By turning the strips 6, 7, the insulating strip 3 is also pressed firmly onto the intermediate webs 12, 13, so that in addition to the frictional connection there is also a positive connection and a permanent, unchangeable connection of the individual components forming the composite is achieved.

Bei dem Ausführungsbeispiel nach der Fig. 3 sind anstelle der hakenförmigen Leisten 17, 18 um eine Achse B verschwenkbare und kaltverformbare Stege 30 vorgesehen, die eine Aufnahmenut 28 an der Innenseite begrenzen. In die Aufnahmenut 28 wird eine Randleiste 25 der Isolierleiste 3 eingeführt. Die Ausgangslage des Steges 30 ist in der Fig. 3 in vollen Linien dargestellt. Die Endlage des Steges 30 ist in gestrichelten Linien angedeutet.In the embodiment according to FIG. 3, instead of the hook-shaped strips 17, 18, cold-deformable webs 30 are provided which can be pivoted about an axis B and which delimit a receiving groove 28 on the inside. An edge strip 25 of the insulating strip 3 is inserted into the receiving groove 28. The starting position of the web 30 is shown in full lines in FIG. 3. The end position of the web 30 is indicated in dashed lines.

Der Steg 30 weist im Bereich seines freien Endes an der der Randleiste 25 zugewandten Seite einen vorspringenden Nocken 27 auf.The web 30 has a projecting cam 27 in the region of its free end on the side facing the edge strip 25.

Der Nutboden 29 der Aufnahmenut 28 erstreckt sich quer zur Innenwand 26 des Metallprofilstabes 2. Auch nach der Anformung des Steges 30 ist zwischen der Randleiste 25 und dem Nutboden ein Spalt vorhanden.The groove bottom 29 of the receiving groove 28 extends transversely to the inner wall 26 of the metal profile bar 2. Even after the web 30 has been formed, there is a gap between the edge strip 25 and the groove bottom.

Die Kräfte, mit denen die Randleisten 25 und auch die Randleisten 15 an die Innenwand 26 der Metallprofilstäbe gepreßt werden, sind durch Pfeile gekennzeichnet, die mit dem Buchstaben F versehen sind.The forces with which the edge strips 25 and also the edge strips 15 are pressed against the inner wall 26 of the metal profile rods are identified by arrows which are provided with the letter F.
