Description

Die Erfindung betrifft ein wärmegedämmtes Verbundprofil zur Herstellung von metallenen Fenstern, Türen u.ä.m., die gleichzeitig eine hohe Maßhaltigkeit und Fugendichtigkeit in bezug auf Feuchtigkeits- und Luftdurchlaß besitzen.The invention relates to a thermally insulated composite profile for the production of metal windows, doors and the like, which at the same time have a high degree of dimensional accuracy and joint tightness with respect to moisture and air permeability.

Bekannterweise wird durch die Trennung eines metallenen Profiles und dessen erneutes, z.B. kraftschlüßiges, Zusammenfügen unter Einbeziehung eines Isolierkörpers, z.B. aus Kunststoff, eine Reduzierung des Wärmeflußes durch das Profil erreicht. Das kraftschlüßige Zusammenfügen stellt dabei bestimmte Voraussetzungen an die Steifigkeit des Isolierkörpers und setzt auch eine spezielle Formausbildung der Kontaktbereiche der Metallprofile und des Isolierkörpers voraus, damit ein festes, gleichzeitig aber maßlich einwandfreies Verbundprofil hergestellt werden kann. Diese Kontaktbereiche haben erfahrungsgemäß eine komplizierte Form. Fertigungsbedingte Toleranzen aller Komponenten erschweren deren Zusammenfügen, z.T. verhindern sie sogar das beabsichtigte Zusammenspiel aller Stege, Nuten, Führungsnasen usw.As is known, the separation of a metal profile and its renewal, e.g. non-positive, joining together with an insulating body, e.g. made of plastic, a reduction in the heat flow through the profile is achieved. The force-fit assembly places certain requirements on the rigidity of the insulating body and also requires a special shape of the contact areas of the metal profiles and the insulating body, so that a firm, but dimensionally perfect composite profile can be produced. Experience has shown that these contact areas have a complicated shape. Manufacturing-related tolerances of all components make it difficult to assemble them, sometimes they even prevent the intended interaction of all webs, grooves, guide lugs etc.

Die DE-OS 2 221 179 und die DE-OS 2 911 832 zeigen Beispiele solcher Ausführungen.DE-OS 2 221 179 and DE-OS 2 911 832 show examples of such designs.

Die beabsichtigte Herstellung eines einwandfreien Verbundprofiles im erstgennten Fall setzt speziell profilierte Zentrierungselemente voraus, die ihrerseits jedoch Einfluß auf die Steifigkeit des Isolierkörpers ausüben mit der Folge, daß nicht immer ein fester, steifer Verbund mit parallelen Außenschalen gewährleistet ist. Das zweite Beispiel mit Zwangsführungen demonstriert den Fall, wo Toleranzen das mit der Formausbildung der Kontaktbereiche bezweckte Zusammenspiel bis zur Unwirksamkeit stören. Entweder ist der Isolierkern im unteren Bereich fest und die oberen Zapfen sind wirkungslos, oder es sind nur die oberen Zapfen fest eingekeilt und es wird wegen des losen unteren Bereiches keine ausreichende Stabilität und Parallelität erreicht.The intended production of a perfect composite profile in the first case requires specially profiled centering elements, which in turn exert an influence on the rigidity of the insulating body, with the result that a firm, rigid bond with parallel outer shells is not always guaranteed. The second example with forced guidance demonstrates the case where tolerances up to the point of ineffectiveness disrupt the interplay aimed at shaping the contact areas. Either the insulating core is fixed in the lower area and the upper pins are ineffective, or only the upper pins are firmly wedged in and insufficient stability and parallelism is achieved due to the loose lower area.

Gewerblich unbefriedigend sind weiterhin Lösungen mit relativ hohem Herstellungsaufwand (Ausfüllen der toleranzbedingter Resträume mit Füllmaterial, vgl. DE-OS 2 122 015) oder solche, bei denen das Endprodukt nicht stabil genug ist (wegen der notwendigen Elastizität der lsolierkernteile für das Einschnappen, vgl. DE-OS 2 754 329).Solutions with relatively high manufacturing costs (filling the tolerance-related residual spaces with filler material, see DE-OS 2 122 015) or those in which the end product is not stable enough are still commercially unsatisfactory (because of the necessary elasticity of the insulating core parts for snapping, see. DE-OS 2 754 329).

Bekannterweise werden die Fugen zwischen den Blend- und Flügelrahmen durch weiche Dichtungen in den inneren und äußeren Anschlagbereichen und/oder eine Dichtung im inneren Falzbereich abgedichtet. Diese s.g. Mitteldichtungen haben einen elastischen, dünneren Kopfbereich (Anschlag) und einen dicke ren Fußbereich (Verankerung). Wegen dieses Aufbaues ist der in den Rahmenecken notwendige Gehrungsschnitt von 45° nicht exakt in einer Ebene ohne besondere Hilfsmittel ausführbar. Die Ecken des Fensters bleiben undicht.As is known, the joints between the frame and casement are sealed by soft seals in the inner and outer stop areas and / or a seal in the inner rebate area. This so-called Center seals have an elastic, thinner head area (stop) and a thicker foot area (anchoring). Because of this structure, the miter cut of 45 ° required in the frame corners cannot be carried out exactly on one level without special aids. The corners of the window remain leaky.

Die übliche Abhilfe wird im Kleben der Gehrungen (wegen der nicht ebenen Schnittfläche bewirken aber Klebungen eine Deformation der Dichtung, außerdem verlieren die Ecken durch den Schnellkleber ihre Elastizität. Beides vermindert die erstrebte Dichtigkeit.), in vorfabrizierten Dichtungsrahmen bzw. vulkanisierten Ecken (beides sind produktionshemmende und teuere Maßnahmen) oder im Aufkleben eines Flickens (vgl. DE-OS 3 133 378). Nach der in der DE-OS 1 157 758 offenbarten technischen Lehre kann eine Mitteldichtung auch zur besseren Wärmedämmung beitragen, wenn sie auf den Isoliersteg aufgeklebt wird, wobei eine kleine Nase desselben als Richtmaß dient.The usual remedy is to glue the mitres (due to the non-flat cut surface, however, gluing causes the seal to deform, and the corners lose their elasticity due to the quick glue. Both reduce the desired tightness.), In prefabricated sealing frames or vulcanized corners (both are production-inhibiting and expensive measures) or by sticking a patch (see. DE-OS 3 133 378). According to the technical teaching disclosed in DE-OS 1 157 758, a center seal can also contribute to better thermal insulation if it is glued to the insulating web, a small nose of which serves as a standard.

Aus den vorstehenden Darlegungen folgt, daß die beiden Aufgaben, Bauöffnungen wärme- und fugendicht abzuschließen, bisher unabhängig voneinander auf getrennten Wegen zu lösen versucht worden ist.It follows from the foregoing that the two tasks of closing building openings in a heat- and joint-tight manner have so far been attempted independently of one another in separate ways.

Der Erfindung liegt daher die Aufgabe zugrunde, die Nachteile der bekannten Lösungsvorschläge zu vermeiden und solch ein wärmegedämmtes Verbundprofil zu schaffen, daß die aus diesem Profil hergestellten Fenster und Türen durch hohe Maßhaltigkeit und Fugendichtigkeit gekennzeichnet sind.The invention is therefore based on the object to avoid the disadvantages of the known solutions and to create such a thermally insulated composite profile that the windows and doors made from this profile are characterized by high dimensional accuracy and joint tightness.

Zur Lösung dieser Aufgabe geht die Erfindung von einem Verbundprofil aus, bestehend aus zwei Metallprofilstäben und mindestens einem, in jeweils eine Klemmnut der Metallprofilstäbe eingreifenden, wärmeisolierenden und einstückig ausgebildeten Isolierstab, der in der jeweiligen Klemmnut durch deren hakenförmig ausgebildete und an den Isolierstab angedrückte Nutstege festgelegt ist, wobei am Isolierstab und in der Klemmnut einander entsprechende Zentrierungsmittel zur Gewährleistung der Maßgenauigkeit beim Andrücken der Nutstege vorgesehen sind. Die Erfindung besteht darin, daß der jeweilige Klemmnutboden eine sich in Richtung zum Isolierstab hin erweiternde, in Querschnitt trapezförmige Zentrierungsnut aufweist, daß die in die Klemmnuten eingreifenden Teile des Isolierstabes einen zu den Metallprofilstäben hin sich verjüngenden, im Querschnitt trapezförmig ausgebildeten Teil aufweist, der in die jeweilige Zentrierungsnut zentrieren eingreift und daß der Isolierstab und/oder die Metallprofilstäbe in ihrer Längsrichtung mindestens eine Leiste aufweisen, an der eine elastische Mitteldichtung befestigbar ist, die diese Dichtung aussteifen und lagemäßig genau festlegen, wobei die Leiste eine dichtende Funktion besitzt. Durch die trapezförmige Zentrierungsnut ist es möglich, auf mit Toleranzen behaftete Zwangsführungen zu verzichten und den Verbund lediglich durch kraftschlüssiges An- und Einpressen von jeweils zwei Nutstegen der maschinell in ihre Endlage gebrachten Metallprofilstäbe zu erreichen. Durch die trapezförmige Zentrierungsnut ist es auch möglich, das endgültige Verbundprofil mit hoher, maschinell einstellbarer Maßgenauigkeit herzustellen. Außerdem wird durch die an dem Isolierstab und/oder den Metallprofilstäben vorgesehene Leiste die elastische Mitteldichtung ausgesteift, so daß der Gehrungsschnitt maschinell durchführbar ist und damit das Fenster eine sehr hohe Dichtigkeit hat.To achieve this object, the invention is based on a composite profile, consisting of two metal profile bars and at least one, in each case engaging in a clamping groove of the metal profile bars, heat-insulating and integrally formed insulating rod, which is fixed in the respective clamping groove by its hook-shaped groove bars pressed onto the insulating rod is, with mutually corresponding centering means are provided on the insulating rod and in the clamping groove to ensure the dimensional accuracy when pressing the groove webs. The invention consists in that the respective clamping groove base has a centering groove which widens in the direction of the insulating rod and has a trapezoidal cross-section, and that the parts of the insulating rod which engage in the clamping grooves have a part which tapers towards the metal profile rods and has a trapezoidal cross section which is in the respective centering groove engages and that the insulating rod and / or the metal profile rods have in their longitudinal direction at least one strip to which an elastic center seal can be attached, which stiffen this seal and define its position precisely, the strip having a sealing function. Thanks to the trapezoidal centering groove, it is possible to dispense with constrained guides and only achieve the bond by force-fitting and pressing in two groove bars each of the metal profile bars that are brought into their end position by machine. Because of the trapezoidal centering groove, it is too possible to produce the final composite profile with high, mechanically adjustable dimensional accuracy. In addition, the elastic center seal is stiffened by the strip provided on the insulating rod and / or the metal profile rods, so that the miter cut can be carried out mechanically and the window therefore has a very high level of tightness.

In den Zeichnungen ist ein Ausführungsbeispiel der Erfindung wiedergegeben. Es zeigen:

In the drawings, an embodiment of the invention is shown. Show it:
  • 1 is an exploded section through the composite profile composed of two metal profile bars and an insulating bar,
  • 2 shows a section through the composite composite profile,
  • 3 shows a section through a window consisting of the composite profiles according to FIGS. 1 and 2,
  • Fig. 4 is a view of a frame-like insulating rod with attached elastic center seal and
  • Fig. 5 shows a section through the elastic center seal and the composite profile.

In Figur 1 ist ein auseinandergezogener Schnitt durch das aus den zwei Metallprofilstäben 1, 2 und einem Isolierstab 3 bestehende Verbundprofil wiedergegeben. Der Isolierstab 3 besteht aus einem wärmeisolierenden Material und ist einstückig ausgebildet. Als wärmeisolierendes Material werden vorzugsweise Kunststoffe eingesetzt. Die Metallprofilstäbe 1, 2 sind nur mit ihren dem Isolierstab 3 zugewandten Seiten wiedergegeben. An diesen Seiten haben die Metallprofilstäbe 1, 2 jeweils Klemmnuten 13, 23, die aus hakenförmig ausgebildeten Nutstegen 111, 112, 211, 212 und dem Klemmnutboden 12, 22 bestehen. Im Klemmnutboden 12, 22 ist jeweils eine sich in Richtung zum Isolierstab 3 hin erweiternde und im Querschnitt trapezförmig ausgebildete Zentrierungsnut 14, 24 vorgesehen.FIG. 1 shows an exploded section through the composite profile consisting of the two metal profile bars 1, 2 and an insulating bar 3. The insulating rod 3 consists of a heat insulating material and is formed in one piece. Plastics are preferably used as the heat-insulating material. The metal profile bars 1, 2 are shown only with their sides facing the insulating bar 3. On these sides, the metal profile bars 1, 2 each have clamping grooves 13, 23, which consist of hook-shaped groove webs 111, 112, 211, 212 and the clamping groove base 12, 22. A centering groove 14, 24, which widens in the direction of the insulating rod 3 and has a trapezoidal cross section, is provided in the clamping groove base 12, 22.

Der Isolierstab 3 besitzt auf beiden Seiten in Richtung auf die Metallprofilstäbe 1, 2 hin, in die Klemmmuten 13, 23 eingreifende Teile 31, 32, die wiederum zu den Metallprofilstäben 1, 2 hin sich verjüngende, im Querschnitt trapezförmig ausgebildete Teile 311, 321 aufweisen. Diese sich trapezförmig verjüngenden Teile 311, 321 greifen zentrierend in die jeweilige Zentrierungsnut 14, 24 ein. In die Teile 31, 32 können außerdem Hakennuten 312, 313, 322, 323 eingeprägt sein, in die die hakenförmigen Nutenstege 111, 112, 211, 212 eingedrückt werden. Es ist jedoch auch möglich, wenn das wärmeisolierende Material, aus dem der Isolierstab 3 besteht, weich genug ist, die Hakennuten 312, 313, 322, 323 fortzulassen und die Nutenstege 111, 112, 211, 212 in die Teile 31, 32 direkt hineinzudrücken. Der Isolierstab 3 besteht außerdem aus den Querstegen 33, 34, die zusammen mit den Teilen 31, 32 einen Hohlraum 35 umschließen. In Figur 1 ist der Profilstab 3 außerdem mit einem vollen Teil 31 und einem röhrenförmigen Teil 32 wiedergegeben. Hiermit sollen lediglich zwei Ausführungsbeispiele wiedergegeben werden, die jedoch nicht gleichzeitig sondern alternativ verwendet werden, d.h. entweder sind beide Teile 31, 32 voll oder röhrenförmig ausgebildet. Ein röhrenförmiges Teil 32 auf beiden Seiten des Isolierstabes 3 hat den Vorteil, daß beim Zentrieren der Metallprofilstäbe 1, 2 und des Isolierstabes 3 durch einen in Figur 2 durch die Pfeile P angegebenen Druck, das Teil 32 um einen geringen Betrag leichter komprimierbar und damit die äußere Maßhaltigkeit des kompletten Verbundprofiles genauer einhaltbar ist. In Figur 2 ist das vollständig montierte Verbundprofil mit an dem Isolierstab 3 anliegenden Nutenstegen 111, 112, 211, 212 wiedergegeben.The insulating rod 3 has on both sides in the direction of the metal profile rods 1, 2, parts 31, 32 which engage in the clamping grooves 13, 23 and which in turn have parts 311, 321 which are tapered in cross section to the metal profile rods 1, 2 . These trapezoidal tapering parts 311, 321 engage in a centering manner in the respective centering groove 14, 24. In addition, hook grooves 312, 313, 322, 323 can be embossed into the parts 31, 32, into which the hook-shaped groove webs 111, 112, 211, 212 are pressed. However, it is also possible if the heat-insulating material from which the insulating rod 3 is made is soft enough to omit the hook grooves 312, 313, 322, 323 and to press the groove webs 111, 112, 211, 212 directly into the parts 31, 32 . The insulating rod 3 also consists of the transverse webs 33, 34 which together with the parts 31, 32 enclose a cavity 35. In Figure 1, the profile bar 3 is also shown with a full part 31 and a tubular part 32. This is intended to reproduce only two exemplary embodiments, which are however not used simultaneously but alternatively, i.e. either both parts 31, 32 are full or tubular. A tubular part 32 on both sides of the insulating rod 3 has the advantage that when the metal profile rods 1, 2 and the insulating rod 3 are centered by a pressure indicated by the arrows P in FIG. 2, the part 32 can be compressed more easily by a small amount and thus the external dimensional accuracy of the complete composite profile can be maintained more precisely. FIG. 2 shows the completely assembled composite profile with grooved webs 111, 112, 211, 212 resting on the insulating rod 3.

Vorzugsweise verlaufen die Wandungen 141, 142, 241, 242 der Zentrierungsnut 14, 24 parallel zu den mit ihnen zentrierend zusammenwirkenden Flächen 314, 315, 324, 325 (Fig. 2) des Isolierstabes 3. Es ist jedoch auch möglich, daß der von den Flächen 314, 315 bzw. 324, 325 beschriebene spitze Winkel um einen kleinen Betrag größer ist als der von den Flächen 141, 142 bzw. 241, 242 beschriebene spitze Winkel.The walls 141, 142, 241, 242 of the centering groove 14, 24 preferably run parallel to the surfaces 314, 315, 324, 325 (FIG. 2) of the insulating rod 3 cooperating with them. However, it is also possible that the of the Surfaces 314, 315 and 324, 325 described acute angle is larger by a small amount than the acute angle described by surfaces 141, 142 and 241, 242.

Bei der Herstellung des Verbundprofiles wird der zunächst in die Klemmnuten 13, 14 eingeschobene Isolierstab 3 durch die von außen in Richtung der Pfeile P gedrückten Metallprofilstäbe 1, 2 in die jeweiligen Zentrierungsnuten 14, 24 zentrierend eingedrückt und anschließend wird durch das Eindrücken oder Anrollen der Nutstege 111,112, 211, 212 in oder an die Teile 31, 32 der Isolierstab 3 mit den Metallprofilstäben 1, 2 zu einer steifen Einheit verbunden.In the manufacture of the composite profile, the insulating rod 3, which is first inserted into the clamping grooves 13, 14, is pressed into the centering grooves 14, 24 by the metal profile rods 1, 2 pressed from the outside in the direction of the arrows P, and is then pressed in by pressing or rolling in the groove webs 111, 112, 211, 212 in or on the parts 31, 32 of the insulating rod 3 connected to the metal profile rods 1, 2 to form a rigid unit.

Die Querschnittsform der in die Klemmmuten 13, 23 eingreifenden Teile 31, 32 des Isolierstabes 3, bezogen auf die Querachse Q zur Längsrichtung der Profilstäbe 1, 2 ist symetrisch ausgebildet. Dieses hat den Vorteil, daß der Isolierstab 3, wie aus Figur 3 ersichtlich ist, sowohl in den Blendrahmen 1a, 2a, als auch in identischer Form im Flügelrahmen 1b, 2b verwendet werden kann. Der Blendrahmen 1a, 2a besteht hier aus dem vollständigen Verbundprofil 1, 2, 3, 4 und der Flügelrahmen 1 b, 2b aus dem Verbundprofil 1, 2, 3 ohne die elastische Dichtung 4 und mit einem um 180° gedrehten Isolierstab 3.The cross-sectional shape of the parts 31, 32 of the insulating rod 3 engaging in the clamping grooves 13, 23, based on the transverse axis Q to the longitudinal direction of the profile rods 1, 2, is symmetrical. This has the advantage that the insulating rod 3, as can be seen from FIG. 3, can be used both in the frame 1a, 2a and in identical form in the sash 1b, 2b. The frame 1a, 2a here consists of the complete composite profile 1, 2, 3, 4 and the casement 1b, 2b of the composite profile 1, 2, 3 without the elastic seal 4 and with an insulating rod 3 rotated by 180 °.

Der Isolierstab 3 weist in seiner Längsrichtung und mittig zu seiner Querachse Q auf einer Seite eine etwa senkrecht verlaufende profilierte Leiste 36 auf. Die Leiste 36 ist auf einer Seite 362 durchgehend profiliert. Auf der anderen Seite 361 ist die Leiste 36 nur am ihrem Fußende profiliert und besitzt oben eine glatte Anschlagfläche. Auf die Leiste 36 ist eine elastische Mitteldichtung 4 aufsteckbar, wie dies in Figur 3 wiedergegeben ist. Durch die Leiste 36, die etwa bis zur Hälfte ihrer Höhe in die Mitteldichtung 4 hineinragt, wird diese bis zu der gestrichelten Linie L in Figur 4 ausgesteift. Das hat den Vorteil, daß der Eckbereich E eine exakt geschnittene Gehrung erhält. Daneben ermöglicht die Leiste 36 die Mitteldichtung 4 gestaucht in den Blendrahmen 1a, 2a einzubauen, so daß im Eckbereich F oberhalb der gestrichelten Linie L die Mitteldichtung 4 auf Grund ihres Strebens, sich zu entspannen, die Gehrung auch ohne Kleber dicht schließt, wie dieses durch die Pfeile S in Figur 4 dargestellt ist.In its longitudinal direction and in the center of its transverse axis Q, the insulating rod 3 has an approximately perpendicular profiled strip 36 on one side. The strip 36 is continuously profiled on one side 362. On the other side 361, the strip 36 is profiled only at its foot end and has a smooth stop surface at the top. An elastic central seal 4 can be plugged onto the strip 36, as shown in FIG. 3. The strip 36, which projects approximately up to half its height into the center seal 4, braces it up to the dashed line L in FIG. This has the advantage that the corner area E receives an exactly cut miter. In addition, the strip 36 allows the central seal 4 to be installed compressed into the frame 1a, 2a, so that the corner area F above the dashed line L Center seal 4 due to its striving to relax, the miter also closes tightly without adhesive, as is shown by the arrows S in FIG. 4.

In Figur 5 ist ein Schnitt durch die elastische Mitteldichtung 4 und Teile des Isolierstabes bzw. der Metallprofilstäbe 1, 2 wiedergegeben. Der Isolierstab 3 wird mit der elastischen Dichtung 4 zu einer funktionellen Einheit verbunden, und zwar dadurch, daß durch eine von außen im Bereich 45 und in Richtung auf den Isolierstab 3 hin wirkende Kraft die Dichtung 4 mit ihrer Aufnahme 42 auf den sie aussteifenden Steg 36 aufgezogen und mit ihren Füßen 46 zwischen den Steg 36 und den Metallprofilen 1, 2 eingeklemmt wird. Für die Einklemmung der Füße 46 sind in diesen auf beiden Seiten Nuten 43 und an den Metallprofilstäbert 1, 2 Leisten 15, 25 vorgesehen. Das fertige Verbundprofil ist im Schnitt in Figur 3 wiedergegeben. Auf diese Weise ist es möglich geworden, beim Zuschneiden der Verbundprofile gleichzeitig auch die Dichtung maschinell exakt zu schneiden und somit dichte Gehrungen herzustellen. Aus Figur 3 ist auch ersichtlich, wie der elastische Kopfteil 41 der am Blendrahmen 1a, 2a gelagerten Mitteldichtung an der glatten Anschlagfläche auf der Seite 361 der Leiste 36 des im Flügelrahmen 1b, 2b gelagerten Isolierstabes 3 zur Anlage kommt.FIG. 5 shows a section through the elastic central seal 4 and parts of the insulating rod or the metal profile rods 1, 2. The insulating rod 3 is connected to the elastic seal 4 to form a functional unit, specifically in that the seal 4 with its receptacle 42 on the web 36 stiffening it acts on it from an outside force in the area 45 and in the direction of the insulating rod 3 pulled up and clamped with their feet 46 between the web 36 and the metal profiles 1, 2. For clamping the feet 46 there are grooves 43 on both sides and 1, 2 strips 15, 25 on the metal profile bars. The finished composite profile is shown in section in Figure 3. In this way it has become possible to cut the gasket mechanically at the same time when cutting the composite profiles and thus to produce tight miters. FIG. 3 also shows how the elastic head part 41 of the center seal mounted on the frame 1a, 2a comes to rest on the smooth stop surface on the side 361 of the strip 36 of the insulating rod 3 mounted in the sash 1b, 2b.
