Description
Die vorliegende Erfindung betrifft ein Hohlkammerprofil für ein Fenster oder eine Tür aus einem Kunststoff, wobei der Kunststoff die Innenwände und die Außenwände des Hohlkammerprofils bildet, wobei die Innenwände und die Außenwände die Hohlkammern des Hohlkammerprofils umgeben und in mindestens eine der Hohlkammern des Hohlkammerprofils mindestens ein Isolierungselement eingesetzt ist. Darüber hinaus betrifft die vorliegende Erfindung eine Rahmenbaugruppe für ein Fenster oder eine Tür, die mindestens einen Profilabschnitt eines derartigen Hohlkammerprofils umfasst.The present invention relates to a hollow chamber profile for a window or a door made of a plastic, the plastic forming the inner walls and the outer walls of the hollow chamber profile, the inner walls and the outer walls surrounding the hollow chambers of the hollow chamber profile and at least one insulating element in at least one of the hollow chambers of the hollow chamber profile is used. In addition, the present invention relates to a frame assembly for a window or a door, which comprises at least one profile section of such a hollow chamber profile.
Hohlkammerprofile für ein Fenster oder eine Tür werden insbesondere aus thermoplastischem Kunststoff erzeugt und in großem Umfang zur Herstellung von Kunststofffenstern und Kunststofftüren eingesetzt. Diese Profile werden ganz überwiegend durch Extrusion aus Hart-PVC (PVC-U) hergestellt. Sie weisen in der Regel mehrere Hohlkammern auf, die durch Innenstege voneinander abgegrenzt sind. Durch das Anordnen einer Anzahl an Hohlkammern hintereinander in der Wärmedurchgangsrichtung durch das Profil, d.h. von der raumseitigen Außenwand zur wetterseitigen Außenwand, wird in solchen Kunststofffenstern und Kunststofftüren eine hohe thermische Isolierung erzielt.Hollow chamber profiles for a window or a door are produced in particular from thermoplastic material and are used on a large scale for the production of plastic windows and plastic doors. These profiles are predominantly made from rigid PVC (PVC-U) by extrusion. As a rule, they have several hollow chambers which are separated from one another by inner webs. By arranging a number of hollow chambers one behind the other in the direction of heat transfer through the profile, i.e. from the room-side outer wall to the weather-side outer wall, high thermal insulation is achieved in such plastic windows and plastic doors.
Allerdings ist man durch das Erhöhen der Anzahl an Kammern, die in dem Profil in der Wärmedurchgangsrichtung hintereinander angeordnet sind, an die Grenzen gestoßen, so dass auf diese Weise nur mehr eine geringfügige weitere Verbesserung der durch ein entsprechendes Kunststofffenster oder eine entsprechende Kunststofftür erzielten thermischen Isolierung zu erreichen ist. Darüber hinaus steigt mit der Anzahl der Innenstege auch der Materialbedarf eines derartigen Hohlkammerprofils. Letztlich beschränkt die Anzahl der Innenstege auch die Geschwindigkeit, mit der ein derartiges Hohlkammerprofil extrudiert werden kann, weil die erforderliche Wärmeabfuhr aus einem Hohlkammerprofil mit entsprechend hoher Anzahl an Innenstegen die Anforderungen an Kühlleistung und Kühlzeit nach der Extrusion erhöhen.However, by increasing the number of chambers arranged one after the other in the profile in the direction of heat transfer, the limits have been reached, so that in this way there is only a slight further improvement in the thermal insulation achieved by a corresponding plastic window or door can be reached. In addition, the material requirement of such a hollow chamber profile increases with the number of inner webs. Ultimately, the number of inner webs also limits the speed at which such a hollow chamber profile can be extruded because the required heat dissipation from a hollow chamber profile with a correspondingly high number of inner webs increases the requirements for cooling capacity and cooling time after extrusion.

An dieser Stelle setzt die vorliegende Erfindung ein, der die Aufgabe zugrunde liegt, ein Hohlkammerprofil für ein Fenster oder eine Tür zur Verfügung zu stellen, das die Nachteile des Stands der Technik zumindest teilweise überwindet. Insbesondere soll das erfindungsgemäße Hohlkammerprofil für ein Fenster oder eine Tür für gleichbleibend hohe thermische Isolierungseigenschaften sorgen und das exakte Einführen des Isolierungselements erleichtern. Darüber hinaus liegt die Aufgabe der vorliegenden Erfindung in der Bereitstellung einer Rahmenbaugruppe für ein Fenster oder für eine Tür, die mindestens einen Profilabschnitt eines derartigen Hohlkammerprofils umfasst.This is where the present invention comes in, which is based on the object of making available a hollow chamber profile for a window or a door that at least partially overcomes the disadvantages of the prior art. In particular, the hollow chamber profile according to the invention should ensure consistently high thermal insulation properties for a window or a door and facilitate the precise insertion of the insulation element. In addition, the object of the present invention is to provide a frame assembly for a window or for a door, which comprises at least one profile section of such a hollow chamber profile.
Diese und andere Aufgaben werden erfindungsgemäß durch ein Hohlkammerprofil mit den Merkmalen des Anspruchs 1 oder durch eine Rahmenbaugruppe mit den Merkmalen des Anspruchs 11 gelöst. Bevorzugte Ausführungsformen der vorliegenden Erfindung sind in den abhängigen Ansprüchen beschrieben.This and other objects are achieved according to the invention by a hollow chamber profile with the features of
Gemäß der vorliegenden Erfindung wurde erkannt, dass der Wärmedurchgang durch ein Hohlkammerprofil dadurch signifikant reduziert werden kann, wenn in eine der Hohlkammern des Hohlkammerprofils ein Isolierungselement eingesetzt ist, dessen Oberfläche zumindest bereichsweise mit einer niedrigemittierenden Beschichtung und/oder einer niedrigemittierenden Folie versehen ist. Eine solche niedrigemittierende Beschichtung oder niedrigemittierende Folie kann als zumindest einseitig aufgebrachte Metallschicht oder als eine zumindest einseitig mit einer Metallschicht versehene Kunststofffolie ausgebildet sein. Ein solches Isolierungselement besitzt bei einem hohen Transmissionsgrad im sichtbaren Bereich des elektromagnetischen Spektrums im infraroten Spektralbereich eine hohe Reflexion und weist damit verbunden eine niedrige Emissivität ("low emissivity", "low E") auf. Dementsprechend hat ein derartiges Isolierungselement den Effekt, den Emissionsgrad im Wellenlängenbereich von 3 µm bis 50 µm, insbesondere im Bereich des Maximums der Wärmestrahlung bei Raumtemperatur (etwa 10 µm) abzusenken. Dadurch wirkt das Isolierungselement als ein guter Reflektor für Wärmestrahlung bei Raumtemperatur und kann in Hohlkammerprofilen wirksam zur Verbesserung der Wärmedämmung eingesetzt werden. Dazu wird auf das Isolierungselement zumindest einseitig eine Metallschicht, beispielsweise eine Aluminium-, Silber-, Gold-, und/oder Kupferschicht, zur Erzeugung der hohen Reflexion im infraroten Spektralbereich aufgebracht. Die Metallschicht kann eine Dicke im Bereich von 5 nm bis 200 µm, vorzugsweise im Bereich von 10 nm bis 25 nm aufweisen. Die Metallschichten sind bevorzugt mit einer Schutzschicht (insbesondere mit antioxidativer Wirkung), einer Dekorschicht, einer Farbschicht, einer Lackschicht, einer Funktionsschicht sowie Kombinationen der genannten Schichten in einer oder mehreren Schichten überzogen. Dadurch kann bei nicht zu hoher Anzahl an Hohlkammern eine gute thermische Isolierungswirkung des Hohlkammerprofils erzielt werden. Darüber hinaus ist bei nicht zu hoher Anzahl an Hohlkammern, in die ein derartiges Isolierungselement eingebracht wird, der Materialeinsatz moderat. Das Isolierungselement bzw. die Isolierungselemente werden nach der Extrusion des Hohlkammerprofils in die entsprechenden Hohlkammern eingebracht, insbesondere eingeschoben. Erfindungsgemäß wird dies dadurch erleichtert, dass mindestens eine der Innenwände der Hohlkammer, in die das mindestens eine Isolierungselement aufgenommen ist, mindestens ein Positionierelement zur Positionierung des mindestens einen Isolierungselements aufweisen. Ein solches Positionierelement sorgt dafür, dass das mindestens eine Isolierungselement leicht in die entsprechende Hohlkammer des Hohlkammerprofils eingeschoben werden kann und nach dem Einschieben in einer definierten Position in der Hohlkammer verbleibt, so dass dessen maximal erzielbare Isolierungswirkung während der Verarbeitung (Verschweißen der Hohlkammerprofile, Transport usw.) und vor allem danach während dessen Verwendung in einem Fenster oder einer Tür erhalten bleibt.According to the present invention, it was recognized that the passage of heat through a hollow chamber profile can be significantly reduced if an insulation element is inserted into one of the hollow chambers of the hollow chamber profile, the surface of which is at least partially provided with a low-emissivity coating and/or a low-emissivity film. Such a low-emission coating or low-emissivity film can be formed as a metal layer applied at least on one side or as a plastic film provided with a metal layer at least on one side. With a high degree of transmission in the visible range of the electromagnetic spectrum, such an insulating element has high reflection in the infrared spectral range and, associated therewith, has low emissivity ("low emissivity", "low E"). Accordingly, such an insulating element has the effect of lowering the emissivity in the wavelength range from 3 μm to 50 μm, in particular in the region of the maximum of thermal radiation at room temperature (about 10 μm). As a result, the insulating element acts as a good reflector for thermal radiation at room temperature and can be used effectively in hollow chamber profiles to improve thermal insulation. For this purpose, a metal layer, for example an aluminum, silver, gold and/or copper layer, is applied to the insulating element at least on one side in order to generate the high reflection in the infrared spectral range. The metal layer can have a thickness in the range from 5 nm to 200 μm, preferably in the range from 10 nm to 25 nm. The metal layers are preferably coated with a protective layer (in particular with an antioxidant effect), a decorative layer, a colored layer, a lacquer layer, a functional layer and combinations of the layers mentioned in one or more layers. As a result, a good thermal insulation effect of the hollow chamber profile can be achieved if the number of hollow chambers is not too high. In addition, if the number of hollow chambers into which such an insulation element is introduced is not too high, the use of material is moderate. After the extrusion of the hollow chamber profile, the insulation element or elements are introduced, in particular inserted, into the corresponding hollow chambers. According to the invention, this is made easier in that at least one of the inner walls of the hollow chamber, in which the at least one insulating element is accommodated, has at least one positioning element for positioning the at least one insulating element. Such a positioning element ensures that the at least one insulating element can be easily pushed into the corresponding hollow chamber of the hollow chamber profile and remains in a defined position in the hollow chamber after being pushed in, so that its maximum achievable insulating effect during processing (welding of the hollow chamber profiles, transport, etc .) and especially afterwards during its use in a window or door.
Dementsprechend liegt der vorliegenden Erfindung in der Bereitstellung eines Hohlkammerprofil für ein Fenster oder eine Tür aus einem Kunststoff, wobei der Kunststoff die Innenwände und die Außenwände des Hohlkammerprofils bildet, wobei die Innenwände und die Außenwände die Hohlkammern des Hohlkammerprofils umgeben, wobei in mindestens eine der Hohlkammern des Hohlkammerprofils mindestens ein Isolierungselement eingesetzt ist, dessen Oberfläche zumindest bereichsweise mit einer niedrigemittierenden Beschichtung und/oder einer niedrigemittierenden Folie versehen ist, wobei sich das Hohlkammerprofil erfindungsgemäß weiter dadurch auszeichnet, dass mindestens eine der Innenwände der Hohlkammer, in die das mindestens eine Isolierungselement aufgenommen ist, mindestens ein Positionierelement zur Positionierung des mindestens einen Isolierungselements aufweist. Darüber hinaus liegt die vorliegende Erfindung weiter in der Bereitstellung einer Rahmenbaugruppe für ein Fenster oder eine Tür, die mindestens einen Profilabschnitt eines erfindungsgemäßen Hohlkammerprofils umfasst.Accordingly, the present invention lies in the provision of a hollow chamber profile for a window or a door made of a plastic, with the plastic forming the inner walls and the outer walls of the hollow chamber profile, with the inner walls and the outer walls surrounding the hollow chambers of the hollow chamber profile, with at least one of the hollow chambers of the hollow chamber profile at least one insulation element is used, the surface of which is provided at least in regions with a low-emissivity coating and/or a low-emissivity film, with the hollow chamber profile being further characterized according to the invention in that at least one of the inner walls of the hollow chamber in which the at least one insulation element is accommodated Having at least one positioning element for positioning the at least one insulating element. In addition, the present invention also lies in the provision of a frame assembly for a window or a door, which comprises at least one profile section of a hollow chamber profile according to the invention.
Hinsichtlich des erfindungsgemäßen Hohlkammerprofils kann es hilfreich sein, wenn das mindestens eine Positionierelement zur Aufnahme einer axialen Kante des mindestens einen Isolierungselements ausgebildet ist. Dadurch kann das mindestens eine Isolierungselement besonders leicht und besonders exakt positioniert in die betreffende Hohlkammer des erfindungsgemäßen Hohlkammerprofils eingesetzt werden. Dazu haben sich Verjüngungen in der Innenwand oder Verjüngungen in erhabenen Positionen der Innenwand der betreffenden Hohlkammer als besonders günstige Ausgestaltungen erwiesen.With regard to the hollow chamber profile according to the invention, it can be helpful if the at least one positioning element is designed to accommodate an axial edge of the at least one insulating element. As a result, the at least one insulation element be used particularly easily and particularly precisely positioned in the relevant hollow chamber of the hollow chamber profile according to the invention. For this purpose, tapers in the inner wall or tapers in raised positions of the inner wall of the hollow chamber in question have proven to be particularly favorable configurations.
Zusätzlich oder alternativ dazu kann es von Vorteil sein, wenn das Hohlkammerprofil mindestens zwei Positionierelemente umfasst, die an zwei einander gegenüberliegenden Innenwänden der Hohlkammer angeordnet sind, in die das mindestens eine Isolierungselement aufgenommen ist. So wird das mindestens eine Isolierungselement klemmend in der vorgesehenen Hohlkammer des erfindungsgemäßen Hohlkammerprofils gehalten, wodurch die Positionsstabilität des mindestens einen Positionierelements in dem erfindungsgemä-ßen Hohlkammerprofil weiter erhöht wird. Zu diesem Zweck kann das mindestens eine Isolierungselement ein leichtes Übermaß im Vergleich zu den Hohlkammerabmessungen aufweisen. Dadurch wird die Klemmwirkung erhöht.In addition or as an alternative to this, it can be advantageous if the hollow chamber profile comprises at least two positioning elements which are arranged on two opposite inner walls of the hollow chamber in which the at least one insulation element is accommodated. The at least one insulation element is held in a clamped manner in the hollow chamber provided in the hollow chamber profile according to the invention, which further increases the positional stability of the at least one positioning element in the hollow chamber profile according to the invention. For this purpose, the at least one insulation element can be slightly oversized compared to the dimensions of the hollow chamber. This increases the clamping effect.
Die Positionierelemente können unabhängig voneinander als eckige oder runde Vertiefungen in den Profilwänden oder als derartige Vertiefungen in erhabenen Stellen des erfindungsgemäßen Hohlkammerprofils ausgebildet sein. Ebenso ist es möglich, dass die Positionierelemente unabhängig voneinander in den Ecken als eckige oder runde Vertiefungen ausgebildet sind, also als Vertiefungen in zwei aneinandergrenzenden Profilwänden des erfindungsgemäßen Hohlkammerprofils darstellen.The positioning elements can be designed independently of one another as square or round depressions in the profile walls or as depressions of this type in raised areas of the hollow chamber profile according to the invention. It is also possible for the positioning elements to be designed independently of one another in the corners as angular or round indentations, ie as indentations in two adjacent profile walls of the hollow chamber profile according to the invention.
Es kann auch günstig sein, wenn das mindestens eine Isolierungselement in die Haupthohlkammer des Hohlkammerprofils eingesetzt ist. Bei der Haupthohlkammer eines Hohlkammerprofils handelt es sich um die Hohlkammer, in die im Regelfall das Verstärkungselement bzw. Armierungselement eingebracht wird. Daher wird diese Haupthohlkammer üblicherweise auch als Armierungskammer bezeichnet. Diese Haupthohlkammer ist üblicherweise diejenige Hohlkammer eines Hohlkammerprofils, die in Richtung der Profiltiefe des Hohlkammerprofils und damit in Richtung des Wärmedurchgangs durch das Hohlkammerprofil die größte Strecke überspannt, ohne dass eine Profilwand vorhanden ist. Daher hat das Einbringen eines Isolierungselements in die Haupthohlkammer einen sehr positiven Einfluss auf die thermischen Isolierungseigenschaften des erfindungsgemäßen Hohlkammerprofils.It can also be favorable if the at least one insulation element is inserted into the main hollow chamber of the hollow chamber profile. The main hollow chamber of a hollow chamber profile is the hollow chamber into which the reinforcing element or reinforcement element is usually introduced. For this reason, this main hollow chamber is usually also referred to as the reinforcement chamber. This main hollow chamber is usually that hollow chamber of a hollow chamber profile which spans the greatest distance in the direction of the profile depth of the hollow chamber profile and thus in the direction of the heat transfer through the hollow chamber profile without a profile wall being present. The introduction of an insulating element into the main hollow chamber therefore has a very positive influence on the thermal insulating properties of the hollow chamber profile according to the invention.
Es kann auch günstig sein, wenn der Kunststoff des Hohlkammerprofils ein thermoplastischer Kunststoff ist. Dabei ist es bevorzugt, wenn der Kunststoff des Hohlkammerprofils im Querschnitt zumindest bereichsweise faserverstärkt, insbesondere glasfaserverstärkt ist. Dies trägt zur mechanischen Stabilität der aus Abschnitten des erfindungsgemäßen Hohlkammerprofils gebildeten Rahmenbaugruppe bei. Dies ist insbesondere deshalb besonders bedeutsam, weil das in der Hohlkammer angeordnete Isolierungselement nicht oder nur geringfügig zur Statik des Hohlkammerprofils und der aus Abschnitten des Hohlkammerprofils gebildeten Rahmenbaugruppe beiträgt.It can also be advantageous if the plastic of the hollow chamber profile is a thermoplastic. It is preferred if the plastic of the hollow chamber profile in the Cross section at least partially fiber reinforced, in particular glass fiber reinforced. This contributes to the mechanical stability of the frame assembly formed from sections of the hollow chamber profile according to the invention. This is particularly significant because the insulating element arranged in the hollow chamber does not contribute, or only slightly, to the statics of the hollow chamber profile and the frame assembly formed from sections of the hollow chamber profile.
Das erfindungsgemäße Hohlkammerprofil lässt sich in vorteilhafter Weise durch ein an sich bekanntes Extrusionsverfahren herstellen. Als Material für das Hohlkammerprofil ist Polyvinylchlorid (PVC), insbesondere Hart-PVC (PVC-U) oder nachchloriertes PVC bevorzugt. Das Material kann bevorzugt auch faserverstärkt, insbesondere glasfaserverstärkt sein. In gewünschte Hohlkammern des Hohlkammerprofils wird jeweils ein Isolierungselement durch Einschieben eingebracht. Das Material des Isolierungselements ist so gewählt, dass es beim Verschweißen von Profilholmen aus dem Hohlkammerprofil nicht störend in Erscheinung tritt. Während des Verschweißens wird das mindestens eine Isolierungselement durch das mindestens eine Positionierelement in seiner gewünschten Position gehalten. Damit sind Polyvinylchlorid (PVC), insbesondere Hart-PVC (PVC-U) oder nachchloriertes PVC, Polyethylen (PE), Polypropylen (PP), Polyethylenterephthalat (PET), Acrylnitril-Butadien-Styrol (ABS) sowie Copolymere und Blends der genannten Polymermateriaien als Kunststoffmaterialien für die metallisierte Kunststofffolie in besonderem Maße geeignet. Die Isolierungselemente werden bevorzugt durch Extrusion des Kunststoffkerns und anschließendes einseitiges oder beidseitiges Beschichten des resultierende Profils mit dem Metall, insbesondere mit Aluminium-, Silber-, Gold-, und/oder Kupfer erhalten. Evtl. Materialschwächungen, die eine geometrische Anpassung der Isolierelemente an die Geometrie der Hohl-Ikammer ermöglichen, in die sie eingebracht werden sollen, werden bevorzugt vor oder nach dem Bedampfen mit Metall in die Kunststofffolie eingebracht. Aber es kann auch günstig sein, wenn das Material des Isolierungselements einen thermoplastischen oder duroplastischen Kunststoff, Papier, Pappe oder Kombinationen der genannten Materialien umfasst.The hollow chamber profile according to the invention can be produced in an advantageous manner by an extrusion process known per se. Polyvinyl chloride (PVC), in particular rigid PVC (PVC-U) or post-chlorinated PVC, is preferred as the material for the hollow chamber profile. The material can preferably also be fiber-reinforced, in particular glass-fiber reinforced. An insulation element is pushed into the desired hollow chambers of the hollow chamber profile. The material of the insulation element is selected in such a way that it does not interfere with the welding of profile bars from the hollow chamber profile. During the welding, the at least one insulation element is held in its desired position by the at least one positioning element. Thus, polyvinyl chloride (PVC), in particular rigid PVC (PVC-U) or post-chlorinated PVC, polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), acrylonitrile butadiene styrene (ABS) and copolymers and blends of the polymer materials mentioned particularly suitable as plastic materials for the metallized plastic film. The insulating elements are preferably obtained by extrusion of the plastic core and subsequent coating of the resulting profile on one or both sides with the metal, in particular with aluminum, silver, gold and/or copper. Any weakenings in the material, which allow the insulating elements to be geometrically adapted to the geometry of the hollow chamber into which they are to be introduced, are preferably introduced into the plastic film before or after the metal has been vapour-deposited. But it can also be favorable if the material of the insulation element comprises a thermoplastic or duroplastic synthetic material, paper, cardboard or a combination of the materials mentioned.
In bevorzugten Ausführungsformen des erfindungsgemäßen Hohlkammerprofils ist das mindestens eine Isolierungselement als zumindest einseitig mit einer Metallschicht versehenes Kunststoffprofil ausgebildet. Dabei ist es besonders bevorzugt, wenn das mindestens eine Isolierungselement als beidseitig mit einer Metallschicht versehenes Kunststoffprofil ausgebildet ist. Auf diese Weise können die thermischen Isolierungseigenschaften des Hohlkammerprofils weiter verbessert werden. Die Metallschicht(en) können eine Dicke im Bereich von 5 nm bis 200 µm, vorzugsweise im Bereich von 10 nm bis 25 nm aufweisen. Die Metallschichten auf beiden Seiten der Kunststofffolie können gleich oder unterschiedlich sein. Darüber hinaus können unterschiedliche Isolierungselemente eines erfindungsgemäßen Hohlkammerprofils einseitig oder beidseitig mit einer Metallschicht versehen sein. Dabei weist das Kunststoffprofil vorzugsweise eine Materialdicke von nicht mehr als 1 mm, besonders bevorzugt in einem Bereich von 100 µm bis 800 µm, insbesondere in einem Bereich von 200 µm bis 600 µm, auf. Eine derartige Dicke der Kunststofffolie bietet eine ausreichende Stabilität bei einem gegenüber dem bei entsprechenden Innenstegen des Hohlkammerprofils erheblich reduzierten Materialaufwand.In preferred embodiments of the hollow chamber profile according to the invention, the at least one insulation element is designed as a plastic profile provided with a metal layer at least on one side. It is particularly preferred if the at least one insulation element is designed as a plastic profile provided with a metal layer on both sides. In this way, the thermal insulation properties of the hollow chamber profile can be further improved. The metal layer (s) can have a thickness in Have range from 5 nm to 200 microns, preferably in the range from 10 nm to 25 nm. The metal layers on both sides of the plastic film can be the same or different. In addition, different insulating elements of a hollow chamber profile according to the invention can be provided with a metal layer on one or both sides. The plastic profile preferably has a material thickness of no more than 1 mm, particularly preferably in a range from 100 μm to 800 μm, in particular in a range from 200 μm to 600 μm. Such a thickness of the plastic film offers sufficient stability with a significantly reduced cost of material compared to the corresponding inner webs of the hollow chamber profile.
Es kann auch günstig sein, wenn das mindestens eine Isolierungselement in Längsrichtung des Hohlkammerprofils mindestens eine Materialschwächung aufweist. Die Materialschwächung(en) ist/sind dabei bevorzugt als Perforation(en) ausgebildet. Durch das gezielte Anordnen der Materialschwächung(en) auf der Kunststofffolie bei der Folienherstellung ist die Herstellung von an den Hohlkammerquerschnitt angepassten Isolierungselementen sehr einfach möglich. Besonders bevorzugt weist ein derartiges Isolierungselement in Längsrichtung des Hohlkammerprofils mehrere Materialschwächungen, insbesondere Perforationen, auf. Diese Perforationen der Isolierungselemente in Längsrichtung ermöglichen ein flexibles Fügen der Kunststofffolie an einen beliebigen Querschnitt der Hohlkammer, in die das jeweilige Isolierungselement eingebracht werden soll.It can also be favorable if the at least one insulation element has at least one material weakness in the longitudinal direction of the hollow chamber profile. The material weakening(s) is/are preferably formed as perforation(s). By specifically arranging the material weakening(s) on the plastic film during the production of the film, it is very easy to produce insulation elements that are adapted to the cross section of the hollow chamber. Such an insulation element particularly preferably has a plurality of material weaknesses, in particular perforations, in the longitudinal direction of the hollow chamber profile. These perforations in the insulation elements in the longitudinal direction allow flexible joining of the plastic film to any cross section of the hollow chamber into which the respective insulation element is to be inserted.
Die erfindungsgemäßen Hohlkammerprofile werden bevorzugt zur Herstellung einer Rahmenbaugruppe eines Kunststoff-Fensters oder einer Kunststoff-Tür verwendet. Durch Verschweißen von auf Gehrung geschnittenen Stücken eines erfindungsgemäßen Hohlkammerprofils kann ein Fenster- oder Türrahmen erhalten werden. Der erhaltene Fenster- oder Türrahmen ist für den Einbau in eine Öffnung einer Wandung eines Gebäudes vorgesehen bzw. in die Öffnung der Wandung eines Gebäudes einbaubar. In alternativen Ausführungsformen ist die vorliegende Erfindung auch auf andere Arten von Profilen anwendbar, beispielsweise auf Aluminium-Kunststoff-Verbundprofile, Holz-Kunststoff-Verbundprofile und dergleichen.The hollow chamber profiles according to the invention are preferably used to produce a frame assembly of a plastic window or a plastic door. A window or door frame can be obtained by welding mitred pieces of a hollow chamber profile according to the invention. The window or door frame obtained is intended for installation in an opening in a wall of a building or can be installed in the opening in the wall of a building. In alternative embodiments, the present invention can also be applied to other types of profiles, for example aluminum-plastic composite profiles, wood-plastic composite profiles and the like.
Das erfindungsgemäße Hohlkammerprofil, die erfindungsgemäße Rahmenbaugruppe sowie jeweils einzelne Teile davon können auch zeilenweise oder schichtweise unter Verwendung eines zeilenaufbauenden oder schichtaufbauenden Fertigungsverfahrens (z. B. 3D-Druck) hergestellt werden, bevorzugt ist jedoch die Herstellung mittels Extrusion oder Coextrusion.The hollow chamber profile according to the invention, the frame assembly according to the invention and individual parts thereof can also be produced line by line or in layers using a line-building or layer-building manufacturing process (e.g. 3D printing), but production by means of extrusion or coextrusion is preferred.
