Abstract

The window frame, of metal cored-foam, uses low-density insulating foam covered by a thin skin of non-porous extrudable thermpolastic. It i made by injecting the foam between the core and the skin, at the time the skin is being extruded. In contrast to known metal-cored frames which use foam as a structural material and have no covering skin, the new frame uses less material and can be made in bright, fadeless colours.

Description

Kunststoff-Fenster-ProfilPlastic window profile

Die Erfindung betrifft ein Kunststoff-Fenster-Profil, bestehend aus einer umsohäumten Metallrohreinlage.The invention relates to a plastic window profile, consisting of a hemmed metal pipe insert.

Durch das Einstecken, Verkleben und Verschrauben von Eckwinkeln in die Metallrohreinlage werden die Kunststoff-Fenster-Profile zu Fensterrahmen verbunden.By inserting, gluing and screwing corner angles in the metal pipe insert, the plastic window profiles are connected to form window frames.

Es ist bekannt, derartige Profile in Formen mit duroplastischem Struktuschaum herzustellen. Alle diese Profile haben jedoch den Nachteil, daß die Materialkosten des duroplastis chen Strukturschaumes zu hoch und die Herstellungszeiten zu lange sind. Außerdem lassen sich die verwendeten duroplastischen Strukturschäume nicht lichtecht in hellen Farben einfärben, so daß eine zusätzliche Lackierung notwendig wird.It is known to have such profiles in molds with thermoset structural foam to manufacture. However, all these profiles have the disadvantage that the material costs of the thermosetting structural foam too high and the production times too long are. In addition, the thermoset structural foams used cannot be used Color lightfast in light colors, so that additional painting is necessary will.

Aufgabe der Erfindung ist es, die vorerwähnten Nachteile zu vermeiden und ein Fensterprofil zu schaffen, das kontinuierlich mit einem verstärkendem Netalirolir aus einem hell durchgefärbten, lichtechten Material gefertigt werden kann.The object of the invention is to avoid the disadvantages mentioned above and to create a window profile that is continuously reinforced with a netalirolir can be made of a light-colored, lightfast material.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Metallrohreinlage mit einem Isolierschaum geringes Dichte und dieser wieder mit einem porenfreien, extrudierfähigen thermoplastischen Kunststoff überzogen ist.According to the invention this object is achieved in that the metal pipe insert with a low-density insulating foam and this again with a non-porous, extrudable thermoplastic is coated.

Die mit der Erfindung erzielten Vorteile bestehen ins--besondere darin, daß durch die kontinuierliche Herstellung Produktionskosten eingespart werden und daß durch die Verwendung des lichtechten thermoplastischen Kunststoffs und die nicht erforderliche zusätzliche Lackierung Materialkosten eingespart werden. Zudem ist der durchgefärbte thermoplastische Kunststoff kratzunempfindlicher, als die aufgespritzte dünne Lackschicht auf den duroplastischen Kunststoff. Außerdem bringt die Kobination Isolierschaum geringer Dichte und Überzug aus einer dünnen Schicht eines extrudierfähigen, thermoplastischen Kunststoffs keine Festigkeitsnachteile gegenüber einem duroplastischen Struktuschaum, dagegen ist beim Isolierschaum jedoch nur ein Bruchteil der Materialmenge wie beim Struktuschaum notwendig.The advantages achieved with the invention consist in particular in that production costs are saved through continuous production and that by using the lightfast thermoplastic material and not required additional painting material costs can be saved. In addition, is the solid-colored thermoplastic material is less sensitive to scratches than the one sprayed on thin layer of varnish on the thermoset plastic. In addition, the combination brings Low-density insulating foam and a thin layer of an extrudable, thermoplastic plastic has no disadvantages in terms of strength compared to a thermosetting plastic Structural foam, on the other hand, is only a fraction of the amount of material used for insulating foam as necessary for the structure foam.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.

Fig. 1 zeigt einen Schnitt des Fensterprofiles nach der Erfindung. Fig. 1 shows a section of the window profile according to the invention.

Der in Fig. 1 gezeigte Schnitt des Fensterprofiles, bestehend aus Flügelrahmenprofil 1 und Blendrahmenprofil 2 zeigt folgenden Aufbau: Metallrohreinlage 3, umsohäumt mit einem Isolierschaum geringer Dichte 4, ummantelt mit einer:dünnen Schicht eines porenfreien, extrudierfähigen thermoplastischen Kunststoffs 6. Die auf ihre bestimmte Länge geschnittenen Profile werden mit Eckwinkeln 5 zu Fensterrahmen verschraubt und verklebt.The section of the window profile shown in Fig. 1, consisting of Sash frame profile 1 and frame profile 2 show the following structure: Metal pipe insert 3, lined with a low-density insulating foam 4, coated with a: thin Layer of a pore-free, extrudable thermoplastic material 6. The Profiles cut to their specific length become window frames with corner brackets 5 screwed and glued.
