Description

Die Erfindung betrifft ein wärmedämmendes Verbundprofil zur Herstellung von Fenstern, Türen od.dgl. aus Aluminium oder einem anderen Metall, das gleichzeitig eine hohe Maßhaltigkeit und Fugendichtigkeit in bezug auf Feuchtigkeits und Luftdurchlaß besitzt.The invention relates to a heat-insulating composite profile for the production of windows, doors or the like. Made of aluminum or another metal, which at the same time has a high degree of dimensional stability and joint tightness with regard to moisture and air permeability.

Es ist bekannt, zur Reduzierung des Wärmeflusses durch ein derartiges Fenster- oder Türprofil, dieses in zwei Schalen zu trennen und zwischen den beiden Schalen einen Isolierkörper einzubringen. Der Isolierkörper kann aus Schaumstoff oder festem Kunststoff bestehen, wobei der Verbund zwischen den Schalen bzw. metallischen Profilstäben und dem Isolierkörper durch eine kraftschlüssige Verbindung, aber auch durch chemische oder thermische Verfahren erfolgen kann. Bei der kraftschlüssigen Verbindung ist es allerdings notwendig, den Isolierkörper in entsprechende Ausnehmungen oder vorspringende Profilstücke einzuschieben, damit er gehalten, zentriert und in einer bestimmten Endlage fest an die Profilstäbe angepreßt werden kann. Hierbei tritt das Problem auf, daß mit jeder zusätzlichen Führungsnase infolge der herstellungsbedingten Toleranzen die beabsichtigte Wirkung einzelner Teile nicht oder nur teilweise erreicht wird.To reduce the heat flow through such a window or door profile, it is known to separate it into two shells and to insert an insulating body between the two shells. The insulating body can consist of foam or solid plastic, and the connection between the shells or metallic profile bars and the insulating body can be achieved by a force-locking connection, but also by chemical or thermal processes. In the case of the non-positive connection, however, it is necessary to insert the insulating body into corresponding recesses or projecting profile pieces so that it held, centered and can be pressed firmly to the profile bars in a certain end position. The problem arises here that the intended effect of individual parts is not or only partially achieved with each additional guide lug due to the manufacturing-related tolerances.

So ist aus der DE-OS 2 221 179 eine Konstruktion bekannt, bei der beide Metall-Rahmenteile an ihren einander zugekehrten Seiten zwischen den beiden Stegen, vorzugsweise mittig dazwischen, einander gegenüberliegende, in Nähe ihrer Enden Hinterschneidungen aufweisende Stege besitzen, während die Profilleiste an ihren beiden anderen, ebenfalls einander gegenüberliegenden Seiten je eine, zu der anderen fluchtende Nut mit einer entsprechenden Hinterschneidung zum Eindrücken der Stege der beiden Metallrahmenteile aufweist. Diese Stege zwischen den beiden eigentlichen Verbindungsleisten sind dazu bestimmt, die Relativlage zwischen den beiden Metallrahmenteilen über die dazwischenliegende Profilleiste festzulegen und damit der Forderung genüge zu tun, die Sichtflächen des äußeren Rahmenteils senkrecht und parallel zueinander zu halten und auch einen Versatz in der Höhe zu vermeiden. Diese Stege erleichtern außerdem den nach ihrem Eindrücken in die Profilleiste erfolgenden Arbeitsgang des Zusammenrollens oder Zusammenpressens der beiden hakenförmigen Leisten, da bei diesem zweiten Arbeitsgang keine Verschiebung, kein Versatz oder dergleichen mehr hervorgerufen werden kann, weil die bereits in den entsprechenden Nuten der Profilleiste verankerten Stege mit ihren Einterschneidungen eine Relativverschiebung zwischen den beiden Metallrahmenteilen verhindern. Herstellungsbedingt weisen jedoch sowohl die Stege als . auch die Kuten Toleranzen auf. Aus diesem Grunde kommt, wenn eine Lagefixierung erreicht werden soll, kein Einschieben, sondern nur ein Eindrücken der Stege in die Nuten in Frage. Dies setzt aber voraus, daß der Profilstab elastisch ausgildet sein muß, weshalb Deformationen des Profilstabes unvermeidbar und ein fester, steifer Verbund der Profilstäbe mit parallelen Außenschalen nicht immer gewährleistet sind.Thus, from DE-OS 2 221 179 a construction is known in which both metal frame parts have on their facing sides between the two webs, preferably in the middle, opposite one another, having undercuts near their ends, while the profile strip on their two other, also opposite sides each have a groove aligned with the other with a corresponding undercut for pressing in the webs of the two metal frame parts. These webs between the two actual connecting strips are intended to determine the relative position between the two metal frame parts via the intermediate profile strip and thus to meet the requirement to keep the visible surfaces of the outer frame part perpendicular and parallel to one another and also to avoid an offset in height . These webs also facilitate the process of rolling or pressing together the two hook-shaped strips after they have been pressed into the profile strip, since no displacement, misalignment or the like can be caused in this second operation, because the crosspieces already anchored in the corresponding grooves of the profile strip with their undercuts prevent a relative shift between the two metal frame parts. Due to production, however, both the webs and. also the kuten tolerances. For this reason, no one comes when a position fix is to be achieved push, but only pressing the webs into the grooves in question. However, this presupposes that the profile bar must be elastic, which is why deformations of the profile bar are unavoidable and a firm, rigid connection of the profile bars with parallel outer shells is not always guaranteed.

Aus der DE-OS 29 11 832 ist eine weitere Konstruktion mit Zwangsführungen bekannt. Danach weist die Isolierleiste schräg nach oben ausgebildete Führungen auf, welche mit seitlich an den Profilstäben angebrachten Zapfen in Wechselwirkung stehen. Gleichzeitig soll aber der Fertigungstoleranzen unterworfene untere Bereich der Isolierleiste mit-der ebenfalls Breitenschwankungen aufweisenden Nut, die zwischen den Zwangsführungen und der inneren Wand des Profilstabes liegt, einen festen Verbund einbringen. Dieses ist aber längerfristig nicht möglich, denn entweder wird die Isolierleiste unten fest eingekeilt, dann sind die Zapfen wirkungslos und bringen nur wirtschaftliche Nachteile oder die Profilleiste wird im Bereich der Zapfen eingekeilt, was keine ausreichende Stabilität und Parallelität der Profilstäbe sichert, da der untere Bereich nicht fest ist. Es sind desweiteren auch Konstruktionen tekannt geworden, die zwar auf besondere Führungsnasen verzichten, den Verbund aber dadurch erreichen, daß entweder die Resträume mit einem Füllmaterial ausgefüllt werden ( DE-OS 21 22 015 ) oder daß das Verbindungsprofil Verankerungsteile aufweist, die zum Einschnappen hinter Innenvorsprüngender Frofilstäbe ausgebildet sein müssen (DE-OS 27 54 329 ). Zu dem Vorteil der wegfallenden Führungsnasen in beiden Fällen, gesellt sich in den beschriebenen Konstruktionen jedoch zum einen der Kachteil des notwendigen Einbringens eines Füllmaterial und zum anderen die notwendige Elastizität des isolierenden Verbindungsprofils, wodurch die Steifigkeit des Verbundprofils im Endzustand herabgesetzt wird.From DE-OS 29 11 832 another construction with positive guidance is known. Thereafter, the insulating strip has guides formed obliquely upwards, which interact with pins attached to the side of the profile bars. At the same time, however, the lower area of the insulating strip, which is subject to manufacturing tolerances, and the groove, which also has width fluctuations and which lies between the positive guides and the inner wall of the profiled bar, should bring in a firm bond. However, this is not possible in the long term, because either the insulating strip is wedged down firmly, then the pins are ineffective and only bring economic disadvantages, or the profile strip is wedged in the area of the pin, which does not ensure sufficient stability and parallelism of the profile bars, since the lower area is not fixed. There have also been known constructions which dispense with special guide lugs, but which achieve the bond by either filling the remaining spaces with a filler (DE-OS 21 22 015) or in that the connecting profile has anchoring parts which snap behind internal projections Profile rods must be formed (DE-OS 27 54 329). To the advantage of the omission of the guide lugs in both cases, however, in the constructions described there is on the one hand the cache part of the necessary introduction of a filler material and on the other hand the necessary elasticity of the insulating material Connection profile, whereby the rigidity of the composite profile is reduced in the final state.

Die Abdichtung zwischen Blend- und Flügelrahmen erfolgt bei bekannten Ausführungen durch weiche Dichtungen in den äußeren Anschlagbereichen der Rahmen und durch weitere, ebenfalls umlaufende weiche Dichtungen im inneren Falzbereich oder durch eine Kombination beider Dichtungen, wobei die in einem der Rahmen fest verankerte Mitteldichtung gegen einen Anschlagbereich des anderen Rahmens beim Schließen angedrückt wird. Bei Verwendung metallischer Profile wird üblicherweise die Mitteldichtung mit entsprechenden Ausnehmungen in ihrem Fußbereich in vorspringende Nasen der Blendrahmenprofile eingelassen.In known designs, the seal between the frame and the sash frame is provided by soft seals in the outer stop areas of the frame and by further, also circumferential soft seals in the inner rebate area or by a combination of both seals, the central seal firmly anchored in one of the frames against a stop area of the other frame is pressed when closing. When using metallic profiles, the center seal with corresponding recesses in its foot area is usually inserted into projecting lugs of the frame profiles.

Aus der DE-OS 1 157 759 ist eine Konstruktion bekannt, bei der die weiche Mitteldichtung auf eine vorspringende Nase eines wärmeisolierenden Kunststoffstabes aufgeklebt wird. Der Zweck dieser Maßnahme besteht zum einen in der Möglichkeit eines-genauen Anbringens der Mitteldichtung beim Kleben und zum anderen darin, daß bei einem Anbringen der Lippendichtung auf dem Kunststoffstab, dieses sich auf die Wärmeisolation günstiger auswirkt, als wenn sie auf einem ganz aus Metall bestehenden Teil aufgesetzt wird.From DE-OS 1 157 759 a construction is known in which the soft center seal is glued to a protruding nose of a heat-insulating plastic rod. The purpose of this measure is on the one hand the possibility of a precise attachment of the center seal when gluing and on the other hand that if the lip seal is attached to the plastic rod, this has a more favorable effect on the thermal insulation than if it were made entirely of metal Part is put on.

Entsprechend den den einzelnen Bereichen einer Mitteldichtung übertragenen Aufgaben ist.diese im Querschnitt sehr unterschiedlich aufgebaut. Sie besitzt einen dünnwandigen, sehr elastischen Kopf- oder Anschlagbereich, der Fertigungstoleranzen und Verformungen des Flügels infolge Winddruckes ausgleichen muß, und einen relativ dickwandigen, zum Teil Hohlkammern aufweisenden Fußbereich, mit dem die Mitteldichtung im Blendrahmen verankert wird. Diese komplizierte Formgestaltung hat neben der noch notwendigen Schrägstellung der Mitteldicbtung zur Folge, daß der bei rechtwinkeligen Rahmen in den Ecken notwendige Gehrungsschnitt von 45° die weiche, verformbare Mitteldichtung nicht exakt in einer Ebene trennt. Die Ecken des Fensters werden dadurch undicht.Depending on the tasks assigned to the individual areas of a center seal, its cross-sectional structure is very different. It has a thin-walled, very elastic head or stop area, which must compensate for manufacturing tolerances and deformation of the wing due to wind pressure, and a relatively thick-walled, partially hollow foot area with which the center seal is anchored in the frame. This complicated design has in addition to the necessary The inclination of the center seal means that the miter cut of 45 ° required for rectangular frames in the corners does not separate the soft, deformable center seal exactly in one plane. This will cause the corners of the window to leak.

Es ist deshalb üblich, die Ecken der Mitteldichtung zu kleben. Nur lassen sich die teilweise gekrümmten Schnittflächen nicht ohne Deformation der gesamten Mitteldichtungsgeometrie aneinanderdrücken und die wegen ihrer schnellen Wirkung verwandten Kleber auf Cyancacrylbasis machen die geklebten Ecken unelastisch. Beides vermindert die erstrebte Dichtigkeit. Um dieses Problem zu umgehen, wurde in der Praxis auch der Weg beschritten, daß entweder komplette vorfabrizierte Dichtungsrahmen oder zumindest vulkanisierte Ecken eingesetzt wurden. Dieser Weg wirkt sich jedoch nachteilig aufdie Produktion aus und ist teuerer.It is therefore common to glue the corners of the center gasket. However, the partially curved cut surfaces cannot be pressed together without deformation of the entire center seal geometry, and the cyanoacrylic-based adhesives used because of their quick action make the glued corners inelastic. Both reduce the desired tightness. In order to avoid this problem, the path was taken in practice that either completely prefabricated sealing frames or at least vulcanized corners were used. However, this route adversely affects production and is more expensive.

Aus der.DE-OS 31 33 378 ist bekannt geworden, die undichten Ecken durch Aufkleben eines "Flickens" abzudichten.It is known from DE-OS 31 33 378 to seal the leaky corners by sticking on a "patch".

Aus den vorstehenden Darlegungen folgt, daß die beiden Aufgaben, nämlich Bauöffnungen wärme- und fugendicht abzuschließen, bisher unabhängig voneinander auf getrennten Wegen zu lösen versucht worden ist.From the above it follows that the two tasks, namely to close building openings heat and joint-tight, have so far been attempted to be solved 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 der 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, im 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 zentrierend 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 errreichen. 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. Die hohe Dichtigkeit wird auch dadurch erreicht, daß die Leiste teilweise mit eine dichtende Funktion übernimmt.To achieve the object, the invention is based on a composite profile consisting of two metal profile bars and at least one, in each case 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, with corresponding centering means on the insulating rod and in the clamping groove to ensure the dimensional accuracy when Pressing the groove webs are provided. The invention consists in the fact 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, 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 centering groove engages in a centering manner and that the insulating rod and / or the metal profiled rods have in their longitudinal direction at least one strip to which an elastic central seal can be attached, which stiffens this seal and precisely defines its position, the strip having a sealing function. Thanks to the trapezoidal centering groove, it is possible to dispense with constrained guides and to achieve the bond simply by force-fitting and pressing in two groove bars each of the metal profile bars that are brought into their end position by machine. Thanks to the trapezoidal centering groove, it is also 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. The high level of tightness is also achieved in that the strip partially takes on a sealing function.

In Figur 1 ist eine 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 Nutstege 111, 112, 211, 212 und dem Klemmnutboden 12, 22 bestehen. Im Klemmnutboden 12, 22 ist je-. weils 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. In the clamping groove bottom 12, 22 is each. because a centering groove 14, 24 which widens in the direction of the insulating rod 3 and has a trapezoidal cross section is provided.

Der Isolierstab 3 besitzt auf beiden Seiten in Richtung auf die Metallprofilstäbe 1, 2 hin, in die Klemmnuten 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 verjüngende 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 kompremierbar 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 the centering groove 14, 24 in a centering manner. 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. Only two exemplary embodiments are intended to be reproduced here, but 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 centering the metal profile rods 1, 2 and the insulating rod 3 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 more precisely maintained. 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 one 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, which are 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 with the metal profile rods 1, 2 connected to a rigid unit.

Die Querschnittsform der in die Klemmnuten 13, 23 eingreifenden Teile 31, 32 des Isolierstabes 3, bezogen auf die Querachse Q zur Längsrichtung der Profilstäbe 1, 2 ist symmetrisch 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 1b, 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 an identical form in the sash 1b, 2b. The window 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 an ihrem Fußende profiliert und besitzt oben eine glatte Anschlagfläche. Auf die Leiste 36 ist eine elastische Mitteldichtung 4 aufsteckbar, wie dieses 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 center 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 compressed in the frame 1a, 2a, so that in the corner area F above the dashed line L, the central seal 4, due to its striving to relax, closes the miter tightly even without adhesive, as is the case with this the arrows S is shown in Figure 4.

In Figur 5 ist ein Schnitt durch die elastische Mitteldichtung 4, eines Teiles des Isolierstabes 3 und der Metallprofilstäbe 1, 2 wiedergegeben. Der Isolierstab 3 wird mit der elastischen Dichtung 4 zu einer funktionellen Einheit verbunden, und zwar dadurch, 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 Metallprofilstäben 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, a part of the insulating rod 3 and the metal profile rods 1, 2. The insulating rod 3 is connected to the elastic seal 4 to form a functional unit, specifically as a result of the force acting on the seal 4 with its receptacle 42 on the web 36 stiffening it from outside in the region 45 and in the direction of the insulating rod 3 and is clamped with its 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. That way it is. It has become possible to cut the gasket mechanically at the same time when cutting the composite profiles, thus producing tight miters. FIG. 3 also shows how the elastic head part 41 of the one mounted on the frame 1a, 2a Middle seal comes to rest on the smooth stop surface on the side 361 of the strip 36 of the insulating rod 3 mounted in the casement 1b, 2b.
