Abstract

Insulating strip (5, 6) comprises insulating parts joined together by bars which move relative to each other. Neighboring bars and the insulating parts pivot in a parallelogram shape when they move. An independent claim is also included for a heat insulating composite profile (1) having two metal profiles (3, 4) and the above insulating strip. Preferred Features: The bars are connected to the insulating parts in the end regions via a hinge or hinge-like region.

Description

Die Erfindung betrifft eine Isolierleiste für ein wärmegedämmtes Verbundprofil für Türen, Fenster oder Fassaden nach dem Oberbegriff des Anspruchs 1.The invention relates to an insulating strip for a thermally insulated composite profile for doors, windows or facades according to the preamble of claim 1.

Ein derartiges Verbundprofil ist aus der EP 0 829 609 B1 bekannt. Das bekannte Verbundprofil besteht aus Metallprofilen und mindestens einer zwischen den Metallprofilen angeordneten und mit den Metallprofilen an den Längskanten schubfest verbundenen, vorzugsweise aus Kunststoff gefertigten Isolierleiste, wobei die Isolierleiste zwei Isolierleistenteile aufweist. Eine mittige Verbindung zwischen den zwei Isolierleistenteilen ist als Gleitführung ausgeführt. Die Gleitführung zwischen den zwei Isolierleistenteilen stellt sicher, dass durch Erwärmung des Verbundprofilteils bedingte Längenausdehnungsunterschiede nicht zu einer unzulässig hohen Durchbiegung des Verbundprofils führen können.Such a composite profile is from the EP 0 829 609 B1 known. The known composite profile consists of metal profiles and at least one arranged between the metal profiles and shear-resistant connected to the metal profiles on the longitudinal edges, preferably made of plastic insulating strip, wherein the insulating strip has two Isolierleistenteile. A central connection between the two Isolierleistenteilen is designed as a sliding guide. The sliding guide between the two Isolierleistenteilen ensures that caused by heating of the composite profile part Längenausdehnungsunterschiede not lead to an unduly high deflection of the composite profile.

Die Idee der Gleitführung wird in der DE 199 56 415 C1 wieder aufgegriffen, wobei die Relativverschieblichkeit, die durch die Gleitführung realisiert wird, nach den Maßnahmen dieser Schrift auf einen vorgegebenen Weg begrenzt wird. Dies wird mittels einer federsteifen Außenbrücke erreicht, welche die Isolierleistenteile miteinander stoffschlüssig oder nicht stoffschlüssig verbindet.The idea of sliding is in the DE 199 56 415 C1 picked up again, wherein the Relativverschieblichkeit, which is realized by the sliding guide is limited to the measures of this document in a predetermined way. This is achieved by means of a spring-stiff outer bridge, which connects the Isolierleistenteile cohesively or non-cohesively.

Die DE 198 53 235 A1 schlägt ein wärmegedämmtes Verbundprofil mit einer Isolierleiste vor, die wiederum zwei mit den Metallprofilen verbundene Isolierleistenteile auf weist, wobei die Isolierleiste zwischen den Isolierleistenteilen einen Bereich erhöhter Elastizität aufweist, der beispielsweise durch ein anderes Material oder durch elastische Stege realisiert werden soll. Diese Lösung hat den Nachteil, dass es die geringe Elastizität des für Isolierleisten verwendeten Materials bei den vorgeschlagenen Konstruktionen in der Regel nicht zulässt, die geforderte Relativbeweglichkeit der Isolierleistenteile zueinander sicherzustellen.The DE 198 53 235 A1 proposes a thermally insulated composite profile with an insulating strip, which in turn has two Isolierleistenteile connected to the metal profiles, wherein the insulating strip between the Isolierleistenteilen has a region of increased elasticity, for example, by another material or by elastic Webs should be realized. This solution has the disadvantage that the low elasticity of the material used for insulating strips in the proposed constructions usually does not allow to ensure the required relative mobility of Isolierleistenenteile each other.

Der Erfindung liegt ausgehend von dem beschriebenen Stand der Technik die Aufgabe zugrunde, alternative, möglichst einfach zu fertigende Isolierleisten für wärmegedämmte Verbundprofile zu schaffen, mit denen es wie mit der Lösung der EP 0 829 609 B1 oder der DE 199 56 415 C1 möglich ist, zu verhindern, dass durch Erwärmung des wärmegedämmten Verbundprofils eine unzulässige hohe Durchbiegung des Verbundprofils auftreten kann.The invention is based on the described prior art, the object to provide alternative, easy to manufacture insulating strips for thermally insulated composite profiles, with which it as with the solution of EP 0 829 609 B1 or the DE 199 56 415 C1 it is possible to prevent that by heating the thermally insulated composite profile an impermissible high deflection of the composite profile may occur.

Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruchs 1. Die Erfindung schafft ferner ein wärmegedämmtes Verbundprofil mit einem derartigen Isolierprofil bzw. mit einer derartigen Isolierleiste.The invention solves this problem by the subject matter of claim 1. The invention further provides a thermally insulated composite profile with such an insulating profile or with such an insulating strip.

Bei allen Ausführungsbeispielen stellen die Stege eine Relativbewegung der Isolierleistenteile relativ zueinander sicher, was durch Gelenke an den Stegen realisiert wird. Dies ist vorteilhaft, da derart auf einfache Weise eine genügend große Relativverschiebung erreicht wird, was im anderen Fall - nach dem Stand der Technik - problematisch ist, wenn die Stege in sich über ihre gesamte Länge elastisch wirken sollen und die Rückstellkräfte aus der elastischen Verformung überwinden müssen, wobei diese Rückstellkräfte eine Spannung implementieren, die, wenn auch verringert, zur Biegeverformung der Isolierleiste führt.In all embodiments, the webs ensure a relative movement of Isolierleistenteile relative to each other, which is realized by joints on the webs. This is advantageous because in such a simple way a sufficiently large relative displacement is achieved, which is problematic in the other case - according to the prior art - if the webs are to act elastically over their entire length and overcome the restoring forces from the elastic deformation These restoring forces implement a tension that, albeit reduced, leads to bending deformation of the insulating strip.

Auftretende thermische Längenänderungen der Profilschalen der Verbundprofile werden durch das parallelogrammartige Verschwenken der Stege ausgeglichen bzw. nicht behindert, so dass Spannungen vermieden werden, die zu einem unerwünschten Durchbiegen des Verbundprofils führen könnten.Emerging thermal changes in length of the profile shells of the composite profiles are compensated by the parallelogram-like pivoting of the webs or not hindered, so that stresses are avoided, which could lead to an undesirable bending of the composite profile.

Im montierten Zustand der Verbundprofile wird vorzugsweise jeweils ein schubfester Verbund zwischen den einzelnen Isolierleistenteilen und den zugehörigen Metallprofilen realisiert.In the assembled state of the composite profiles, a shear-resistant bond between the individual Isolierleistenteilen and the associated metal profiles is preferably realized in each case.

Temperaturschwankungen werden durch die parallelogrammartige Bewegung gem. Figur 3 ausgeglichen. Relativbewegungen zwischen den Isolierleistenteilen sind vorzugsweise in einem Bereich zwischen 2 mm und 10 mm, insbesondere in einem Bereich zwischen 2 mm und 6 mm möglich.Temperature fluctuations are due to the parallelogram movement. FIG. 3 balanced. Relative movements between the Isolierleistenteilen are preferably in a range between 2 mm and 10 mm, in particular in a range between 2 mm and 6 mm possible.

Die Stege sind derart steif ausgestaltet, dass keine Längenveränderungen der Stege auftreten. Sie sind druck- und zugstabil.The webs are designed so stiff that no changes in length of the webs occur. They are resistant to pressure and tension.

Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous embodiments of the invention can be found in the dependent claims.

Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen unter Bezug auf die Zeichnung näher beschrieben. Es zeigt:

Figur 1 zeigt einen Schnitt durch ein beispielhaftes wärmegedämmtes Verbundprofil 1, das rein beispielhaft für einen Blendrahmen eines Fensters geeignet ist. FIG. 1 shows a section through an exemplary thermally insulated composite profile 1, which is purely exemplary of a window frame of a window suitable.

Das Verbundprofil 1 weist Metallprofile 3, 4 auf, die hier beispielhaft durch zwei Isolierleisten bzw. -stege 5, 6 miteinander verbunden sind.The composite profile 1 has metal profiles 3, 4, which are connected by way of example by two insulating strips or webs 5, 6 together.

Die Isolierleisten 5, 6, die entsprechend der Figur 1 die Metallprofile 2, 3 miteinander verbinden, weisen mehrere Isolierleistenteile bzw. Isolierleistenteilabschnitte auf.The insulating strips 5, 6, according to the FIG. 1 the metal profiles 2, 3 interconnect, have several Isolierleistenteile or Isolierleistenteilabschnitte.

So weisen die Isolierleisten 5 der Figur 2 einen ersten Isolierleistenteil 7 auf, der im montierten Zustand mit einem Führungsausleger in das eine Metallprofil 3 eingreift.Thus, the insulating strips 5 of FIG. 2 a first Isolierleistenteil 7 which engages in the mounted state with a guide arm in the one metal profile

Die Isolierleiste 5 weist ferner einen zweiten Isolierleistenteil 8 auf, der mit einem weiteren Führungsausleger in das zweite Metallprofil 4 eingreift.The insulating strip 5 also has a second Isolierleistenteil 8, which engages with a further guide arm in the second metal section 4.

Die beiden Isolierleistenteile 7, 8 der Isolierleiste 5 sind über mehrere Stege 10, 11 hier stoffschlüssig miteinander verbunden.The two Isolierleistenteile 7, 8 of the insulating strip 5 are connected via a plurality of webs 10, 11 here cohesively with each other.

Die beiden Isolierleistenteile 7, 8 der Isolierleiste 5 sind axial in ihrer Haupterstreckungsrichtung vorzugsweise durchgehend ausgebildet.The two Isolierleistenteile 7, 8 of the insulating strip 5 are preferably designed to be continuous axially in their main extension direction.

Die Stege 10, 11 sind derart ausgestaltet, dass die beiden Isolierleistenteile 7, 8 der Isolierleiste 5 begrenzt relativ zueinander beweglich sind, derart, dass zueinander benachbarte Stege 10, 11- hier aus der Rechteckform der Fig. 2 - in eine Parallelogrammform - Fig. 3 - bewegt werden. Dazu muß jeder Steg in seinen voneinander abgewandten Endbereichen jeweils über ein Gelenk 9 mit den Isolierleistenteilen 7, 8 verbunden sein.The webs 10, 11 are configured such that the two Isolierleistenteile 7, 8 of the insulating strip 5 are limited relative to each other movable, such that adjacent webs 10, 11- here from the rectangular shape of Fig. 2 - in a parallelogram form - Fig. 3 - be moved. For this purpose, each web must be connected in its opposite end portions each have a hinge 9 with the Isolierleistenteilen 7, 8.

Die Gelenke 9 können auf verschiedene Weise ausgestaltet sein, so als filmgelenkartige dünne Materialanbindungen zwischen den Stegen 10, 11 und den Isolierleistenteilen bzw. Isolierleistenteilabschnitten 7, 8 (Fig. 2; Stege 10 und 11) oder Zapfen/Lageraugekonstruktionen mit separaten Stegen 19, 24, welche an die Isolierleistenteile bzw. Isolierleistenteilabschnitte 7, 8 angelenkt sind (Fig. 6, 7).The joints 9 can be designed in various ways, so as a film-joint-like thin material connections between the webs 10, 11 and the Isolierleistenteilen or Isolierleistenteilabschnitten 7, 8 ( Fig. 2 ; Webs 10 and 11) or journal / Lageraugekonstruktionen with separate webs 19, 24, which are hinged to the Isolierleistenteile or Isolierleistenteilabschnitte 7, 8 ( Fig. 6 . 7 ).

Dies sei nachstehend näher erläutert.This will be explained in more detail below.

Die Stege 10, 11 können beispielsweise durch ein Ausstanzen erzeugt werden.The webs 10, 11 can be generated for example by punching.

Rein beispielhaft sind in Figur 2 und 3 zwei verschiedene Arten von Stegen 10, 11 dargestellt.Purely by way of example are in FIGS. 2 and 3 two different types of webs 10, 11 shown.

So zeigt die Figur 2 einerseits einen Steg 10, der in der Mitte dicker und nach außen hin dünner (nahezu trapezartig) ausgestaltet ist, so dass seine Anlenkbereiche an die Isolierleistenteile selbst als Gelenke 9 wirken, so dass es möglich ist, den einen Isolierleistenteil 7 relativ zum anderen Isolierleistenteil 8 zu bewegen, wobei sich die Stege 10 parallelogrammartig verschwenken (Figur 3).That's how it shows FIG. 2 on the one hand, a web 10, which is thicker in the middle and outwardly thinner (almost trapezoidal) is designed so that its hinge portions act on the Isolierleistenteile itself as joints 9, so that it is possible, the one Isolierleistenteil 7 relative to the other Isolierleistenteil. 8 to move, with the webs 10 pivot parallelogram ( FIG. 3 ).

Die Stege 11 weisen dagegen über den größten Teil ihrer Länge eine größere Breite auf und sind lediglich im Bereich der Übergänge zu den Isolierleistenteilen 7, 8 über Einschnürungen bzw. filmscharnierartige Verengungen 12, 13 mit den Isolierleistenteilen 7, 8 verbunden, so dass die Isolierleistenteile 7, 8 relativ zueinander beweglich sind. Die Verengungen 12, 13 wirken hier als filmscharnierartige Gelenke 9, so dass sich die Stege 11 bei einem wärmebedingten Auslenken wiederum parallelogrammartig verschwenken (Figur 3).On the other hand, the webs 11 have a greater width over most of their length and are connected to the insulating strip parts 7, 8 via constrictions or film-hinge-like constrictions 12, 13 only in the region of the transitions to the insulating strip parts 7, 8, so that the insulating strip parts 7 , 8 are movable relative to each other. The constrictions 12, 13 act here as film hinge-like joints 9, so that the webs 11 in turn turn parallelogram-like in a heat-induced deflection ( FIG. 3 ).

Optimal ist es, wenn sich die Stege 10, 11 als Querstege senkrecht zur Längsachse bzw. zur Axialachse der Isolierleiste erstrecken, denn in diesem Fall wirkt sich die Querkontraktion der Isolierleiste (Figur 3), egal in welche Richtung, nur gering aus. Die Querkontraktion ist aber im praktischen Fall so klein, dass sie im montierten Zustand hinsichtlich ihrer Effekte vernachlässigt werden kann.It is optimal if the webs 10, 11 extend as transverse webs perpendicular to the longitudinal axis or to the axial axis of the insulating strip, because in this case, the transverse contraction of the insulating strip ( FIG. 3 ), no matter in which direction, only small. However, the transverse contraction is so small in the practical case that it can be neglected in the assembled state with regard to their effects.

Die Stege sollten zudem relativ lang sein bzw. die Isolierleistenteile 7, 8 möglichst kurz, damit sich ein möglichst großer Schwenkradius ergibt.The webs should also be relatively long or the Isolierleistenteile 7, 8 as short as possible, so as to give the largest possible swing radius.

Gemäß Figur 4 und Figur 5 ist es möglich, eine Sichtverblendung der Ausstanzungen 14 zwischen den Stegen 10, 11 vorzunehmen. Diese Sichtverblendung kann mittels einer oder mehrerer Folien 15, 16 erfolgen, die nach dem Ausstanzen der Isolierleisten zu bildender Stege 10, 11 für eine oder beide Seiten der Isolierstege aufgebracht werden oder in Nuten 2 in den Isolierleistenteilen 7, 8 eingreifenAccording to FIG. 4 and FIG. 5 It is possible to make a visual veneering of the punch-outs 14 between the webs 10, 11. This blindfold can take place by means of one or more foils 15, 16, which are applied to the forming webs 10, 11 for one or both sides of the insulating bars after punching out of the insulating strips or engage in grooves 2 in the insulating strip parts 7, 8

Diese Folien müssen so dünn bzw. elastisch sein, dass die Bewegung der Isolierprofilteile 7, 8 relativ zueinander durch sie nicht verhindert wird.These films must be so thin or elastic that the movement of the Isolierprofilteile 7, 8 relative to each other is not prevented by them.

Es bietet sich daher an, eine schaumartige Masse zum Ausbilden der Folien 15, 16 zu verwenden.It is therefore appropriate to use a foam-like mass for forming the films 15, 16.

Denkbar ist es alternativ auch, die Ausstanzungen 14 direkt nach dem Ausstanzen mit einem Schaum auszufüllen und derart eine Sichtverblendung zu realisieren.Alternatively, it is also conceivable to fill the punch-outs 14 with a foam immediately after punching and to realize such a blind veneer.

Diese Maßnahmen sind auch bei den Ausführungen der Fig. 6 und 7 sinnvoll, die nachfolgend beschrieben werden.These measures are also in the remarks of Fig. 6 and 7 useful, which are described below.

Danach ist es auch denkbar, die Isolierleistenteile 7, 8 der Isolierleiste 5 vollständig voneinander zu trennen. Auf diese Weise wird eine mehrstückige Isolierleiste realisiert.Thereafter, it is also conceivable, the Isolierleistenteile 7, 8 of the insulating strip 5 completely separate from each other. In this way, a multi-piece insulating strip is realized.

Nach Figur 6 weisen die Stege 19 zapfenartige Ausleger 17 auf, die in korrespondierend geformte, lageraugenartige Aussparungen 18 der Isolierleistenteile 7, 8 eingreifen, wobei durch die zapfenartigen Ausleger 17 in den Ausnehmungen 18 an beiden Seiten der Stege 19 die Beweglichkeit der Isolierleistenteile 7, 8 über zwei Gelenke 9 in eine Parallelogrammstellung nach Art der Fig. 3 gewährleistet wird.To FIG. 6 the webs 19 pin-like arms 17 which engage in correspondingly shaped, bearing-eye-like recesses 18 of the Isolierleistenteile 7, 8, wherein the mobility of the Isolierleistenteile 7, 8 via two joints by the pin-like boom 17 in the recesses 18 on both sides of the webs 19 9 in a parallelogram by type Fig. 3 is guaranteed.

Voraussetzung ist, dass die Isolierleistenteile 7, 8 jeweils derart ausgestaltet sind bzw. Ausnehmungen 21 aufweisen, dass die Schwenkbewegung der Stege 19 nicht behindert wird.The condition is that the Isolierleistenteile 7, 8 are each configured or have recesses 21, that the pivotal movement of the webs 19 is not hindered.

Die Figuren 6c und 6d veranschaulichen, dass auf die Stege 15 seitliche Abdeckplatten 20 aufgebracht bzw. an diese angeformt sein können, welche wiederum einen Sichtschutz bzw. eine Abdeckung für die Ausnehmungen 21 darstellen.The FIGS. 6c and 6d illustrate that on the webs 15 side cover plates 20 may be applied or formed on this, which in turn constitute a privacy screen or a cover for the recesses 21.

Hier sind die Isolierleistenteile 7, 8 nicht mehr einstückig miteinander verbunden, sie bilden aber insgesamt immer noch eine Isolierleiste bzw. stellen Isolierleistenteile einer übergreifenden Isolierleiste dar.Here, the Isolierleistenteile 7, 8 are no longer integrally connected to each other, but they still form a total insulating strip or provide Isolierleistenteile an overarching insulating strip.

Figur 6e veranschaulicht eine weitere Variante, nach der die Ausleger 17 selber wiederum vorzugsweise nach außen offene Aussparungen 22 aufweisen können, die den Ausleger 17 elastisch ausbilden, um ein einfaches Einklipsen der Ausleger 17 in die Ausnehmungen 18 zu ermöglichen. FIG. 6e illustrates a further variant, according to which the boom 17 itself may in turn preferably have outwardly open recesses 22 which form the boom 17 elastic to allow easy clipping of the boom 17 in the recesses 18.

Figur 7 zeigt ein weiteres Ausführungsbeispiel der Erfindung, bei dem die Isolierleistenteile 7, 8 durch einen schmalen Spalt 25 voneinander getrennt sind. An die Isolierleistenteile 7, 8 sind Stege 24 angelenkt. FIG. 7 shows a further embodiment of the invention, in which the Isolierleistenteile 7, 8 are separated by a narrow gap 25 from each other. At the Isolierleistenteile 7, 8 webs 24 are articulated.

Dieses Anlenken erfolgt vorzugsweise auf einfache Weise mittels Zapfen.This articulation is preferably done in a simple manner by means of pins.

Diese Zapfen sind hier als Spreizzapfen 26 ausgebildet, die einen Kopf und zusammendrückbare Füße 28 aufweisen. Der Kopf kann auch nach Art der Fig. 7c einstückig bzw. stoffschlüssig mit dem Steg 24 (oder mit dem Isolierleistenteil 7, 8) ausgestaltet sein bzw. direkt von den Stegen 24 gebildet werden.These pins are here designed as a spreader pin 26 having a head and squeeze feet 28. The head can also be sort of Fig. 7c one piece or cohesively with the web 24 (or with the Isolierleistenteil 7, 8) be configured or formed directly from the webs 24.

Der Zapfen 26 wird durch eine Bohrung 29 des Isolierleistenteils 7 gesteckt, so dass er sich aufspreizt, wenn er dieses ganz durchsetzt. Diese Art der Montage ist besonders einfach.The pin 26 is inserted through a bore 29 of the Isolierleistenteils 7, so that it spreads when he passes through this completely. This type of assembly is particularly easy.

Der Spreizzapfen kann auch separat ausgestaltet sein und zur Montage durch korrespondierende Durchgangsbohrungen der aufeinander gelegten Stege 24 und der Isolierleistenteile 7, 8 durchgesteckt werden, wobei sich die Füße 28 nach dem Durchtritt durch die beiden Bohrungen wieder aufweiten.The Spreekapfen can also be configured separately and for mounting through corresponding through holes of the superimposed webs 24 and the Isolierleistenteile 7, 8 are pushed through, with the feet 28 widen again after passing through the two holes.
