Abstract
Description
Die Erfindung bezieht sich auf ein Verbundprofil für Rahmen von Fenstern, Türen oder dgl., mit einem Metall-Hohlprofil, das auf seinen zur Außen- und Innenseite des Rahmens hin liegenden Profilseiten jeweils mit einer Kunststoffbedeckung versehen ist.The The invention relates to a composite profile for frames of windows, doors or Like., With a metal hollow profile, on its to the outside and Inside of the frame lying profile sides each with a Plastic cover is provided.
Es ist bekannt, für die Rahmen von Fenstern, Türen oder dgl. Kunststoff-Hohlprofile einzusetzen, die im Inneren mit Stahlrohren ausgesteift werden. Dabei liegt das Stahlrohr aber nicht über seinen gesamten Außenumfang hinweg an der Innenwand des Hohlprofils an, sondern es hat vielmehr Luft um seine Außenfläche herum und wird nur über äußere, an der Innenwand des Kunst-Hohlprofils angebrachte Stege gegenüber dieser abgestützt, wobei auch dabei in der Regel noch etwa 1 mm Luft gegenüber den Stegen verbleibt, weil bei der Herstellung der meist aus Hart-PVC bestehenden Kunststoff-Hohlprofile deren Innenkontur (und damit auch die Ausbildung der Stege an dieser) mit akzeptablen Kosten nicht mit so geringen Toleranzen hergestellt werden können, daß keinerlei Spiel mehr verbleibt. Daneben weisen auch die einzuführenden Stahlrohre deutliche Toleranzen auf.It is known for the frames of windows, doors or the like. Use plastic hollow sections, the inside with Steel pipes are stiffened. But the steel tube is not above his entire outer circumference on the inner wall of the hollow profile, but it has rather Air around its outer surface and is only about outside, on the inner wall of the art-hollow profile mounted webs with respect to this supported although also usually about 1 mm of air over the Webs remains because in the manufacture of mostly hard PVC existing plastic hollow profiles whose inner contour (and thus also the training of the webs at this) with acceptable costs can not be made with such tight tolerances that no Game remains more. In addition, also have to be introduced Steel tubes clear tolerances.
Deshalb werden die in das PVC-Hohlprofil eingeführten Versteifungsrohre dann mit diesem verschraubt, wobei das PVC-Profil an den Verschraubungsstellen zum Stahlrohr hin gezogen wird und die Verschraubung üblicherweise nur einseitig am Profil, und dort falzseitig, erfolgt. Die Hauptkräfte (thermische Belastung o.ä.) auf den Fensterrahmen wirken aber im wesentlichen senkrecht zur Richtung der Befestigungsschrauben. Deshalb kommt es dazu, daß, bevor in der Hauptbelastungsrichtung das Stahlprofil gegen die Stützstege zur Anlage kommt, der Kunststoff-Hohlprofilstahl z. B. wegen der auftretenden thermischen Belastung über seine Länge hinweg krumm wird, und zwar infolge der unterschiedlichen thermischen Ausdehnung auf seine Außen- und Innenseite. Aber erst, wenn das Stahlrohr an den Stützstegen anliegt, kann es Kräfte aufnehmen, wobei dann aber der Kunststoff-Hohlprofil-Stab oftmals schon deutlich krumm ist.Therefore be introduced into the PVC hollow profile stiffening tubes then screwed with this, with the PVC profile at the screw joints is pulled towards the steel tube and the screw usually only on one side of the profile, and there on the rebate, done. The main forces (thermal Load or similar) but act on the window frame substantially perpendicular to Direction of the fixing screws. Therefore, it happens that, before in the main load direction, the steel profile against the support webs comes to rest, the plastic hollow profile steel z. B. because of occurring thermal stress over its length becomes crooked, and Although due to the different thermal expansion on his Outside- and inside. But only when the steel pipe at the supporting webs it can be forces, it can take, but then the plastic hollow profile rod often already is clearly crooked.
Aus
der
Üblicherweise werden solche Kunststoffprofile vom Verarbeiter auf Gehrung geschnitten und stumpf mit dem Gegenprofil an der Profilecke verschweißt. Bei diesem bekannten, kunststoffummantelten Rahmenprofil muß hierzu das Aluminium mit durchschnitten werden, was aber Schwierigkeiten ergibt, wenn danach eine Verschweißung bei 250°C durchgeführt werden soll. Denn beim Verschweißen des PVC wird dieses um ca. 3 mm aufgeschmolzen, ein Vorgang, dem das Aluminium jedoch nicht folgt, so daß dann die direkte Verschweißung mit dem Gegenprofil an der Gehrungsfläche nicht mehr möglich ist. Deshalb braucht man bei diesem bekannten Verbundprofil eine andersartige Verbindungstechnik an den Gehrungsstellen. Hierzu werden z.B. fertige Aluminium-Winkel in das Aluminium-Rohr formschlüssig eingeschoben, das Gegenprofil aufgesteckt und die Gehrungsflächen anschließend verklebt, wobei gegebenenfalls auch noch mechanische Befestigungsmittel ergänzend benutzt werden. Auch der Aluminium-Winkel wird im Aluminium-Rohr durch Verklebung befestigt. Damit ergibt sich aber die Notwendigkeit einer außerordentlich aufwendigen Verbindungstechnik an den Gehrungsstellen bei der Verarbeitung dieses bekannten Verbundprofils.Usually Such plastic profiles are mitred by the processor and butt welded to the mating profile at the profile corner. at this known, plastic-coated frame profile must this the aluminum will be cut through, but that's a problem results when welding is then performed at 250 ° C should. Because when welding the This PVC is melted by about 3 mm, a process that the Aluminum, however, does not follow, so that then the direct welding with the counter profile on the miter surface is no longer possible. Therefore you need a different type in this known composite profile Connection technology at the miter points. For this, e.g. finished Aluminum angle inserted positively into the aluminum tube, the counter profile attached and the miter surfaces subsequently glued, where appropriate, even mechanical fasteners additional to be used. The aluminum angle is also in the aluminum tube attached by gluing. But this results in the necessity one extraordinary elaborate connection technology at the miter points in the processing of this known composite profile.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, ein Kunststoff-Rahmenprofil für Fenster, Türen oder dgl. vorzuschlagen, das bei gleichfalls hervorragender Steifigkeit und ohne Spiel zwischen der metallischen Einlage und deren Kunststoffbedeckung vom Verarbeiter zum Bau des gewünschten Rahmens an den Gehrungsstellen am Gegenprofil weniger aufwendig befestigt werden kann und einen einfachen Aufbau aufweist.outgoing This is the object of the invention, a plastic frame profile for windows, Doors or Like. Propose that with equally excellent rigidity and without play between the metallic insert and its plastic covering from the processor to the construction of the desired Frame at the miter points on the counter profile less expensive can be attached and has a simple structure.
Erfindungsgemäß wird dies bei einem Verbundprofil der eingangs genannten Art dadurch erreicht, daß jede Kunststoffbedeckung in Form eines Kunststoffteiles vorgesehen ist, bei dem an seiner dem Metall-Hohlprofil zugewandten Seite zu diesem hin gerichtete Halterungsvorsprünge angeformt sind, die in entsprechende Formaufnahmen am Metall-Hohlprofil formschlüssig eingreifen und eine spielfreie Befestigung des Kunststoffteiles am Metall-Hohlprofil bewirken.According to the invention this is achieved by a composite profile of the type mentioned, that each Plastic cover is provided in the form of a plastic part, in the case of its metal hollow profile side facing this towards directed support projections are formed, which engage positively in corresponding form receptacles on the metal hollow profile and a play-free attachment of the plastic part to the metal hollow profile cause.
Das erfindungsgemäße Verbundprofil weist zunächst den großen Vorteil eines modularen Aufbaus auf, wie er bei einer Ummantelung eines innenliegenden Metall-Hohlprofils durch Kunststoff in einem Extrusionswerkzeug oder durch Umspritzen o.ä. nicht gegeben ist. Damit wird es möglich, daß die Einzelteile dieses modularen Verbundprofils vom Verarbeiter voneinander getrennt an der Einsatzstelle so in richtiger Länge abgeschnitten werden können, daß beim anschließenden Zusammenfügen derselben an den Gehrungsstellen des so entstandenen Verbundprofilstücks jeweils ein geeigneter Überstand der Kunststoffteile über das zwischen ihnen angebrachte Metall-Hohlprofil so gegeben ist, daß diese beim anschließenden Verschweißen um die dabei erforderliche Länge aufgeschmolzen werden können, ohne daß hierbei das dazwischen vorliegende Metall-Hohlprofil stört. Dann kann auch ein üblicher Kunststoff-Eckverbinder eingesetzt und, wie üblich, verschweißt werden. Des Einsatzes einer speziellen Verbindungstechnik bedarf es hierbei nicht.The composite profile according to the invention initially has the great advantage of a modular structure, as it o.ä. In a casing of an inner metal hollow profile by plastic in an extrusion die or by molding. is not given. This makes it possible that the items of this modular composite profile separated from the processor can be cut off at the site so in proper length that during subsequent assembly of the same at the miter points of the resulting composite profile piece each have a suitable projection of the plastic parts on the attached metal between them Hollow profile is given so that they can be melted during the subsequent welding to the required length, without that in this case disturbs the interposed metal hollow profile. Then, a conventional plastic corner connector can be used and, as usual, be welded. The use of a special connection technology is not required here.
Auch bei dem erfindungsgemäßen Verbundprofil ist das mittige Metall-Hohlprofil (Trägerprofil) mit der seitlichen Kunststoffbeplankung spielfrei verbunden, wodurch sich eine hervorragende Steifigkeit ergibt.Also in the composite profile according to the invention is the central metal hollow profile (carrier profile) with the lateral Plastic sheeting connected without backlash, resulting in a superb Stiffness results.

erfindungsgemäße Verbundprofil
bietet aber darüber
hinaus auch noch eine Mehrzahl weiterer Vorteile:

modularen Aufbaus des erfindungsgemäßen Verbundprofils besteht

Seitenteile einsetzen zu können,

hierdurch unterschiedliche Außenkonturen
des zu erstellenden Rahmens erzeugen lassen, ohne daß hierzu
entsprechend unterschiedliche Verbundprofile vorgehalten werden
müßten.However, the composite profile according to the invention also offers, in addition, a plurality of further advantages:
Due to the modular structure of the composite profile according to the invention, it is possible to use different side panels when using one and the same metal hollow profile, so that this can produce different outer contours of the frame to be created, without the need correspondingly different composite profiles should be kept.
Bislang war es auch erforderlich, für jede Farbgestaltung des betreffenden Rahmens ein entsprechend farbiges Kunststoffprofil als Gesamtteil auf Lager zu halten. Bei dem erfindungsgemäßen Verbundprofil ist dies nicht mehr erforderlich, da aufgrund dessen modularen Aufbaus hier nur entsprechend farbig unterschiedliche Seitenteile gelagert werden müssen.So far it was also necessary for each color design of the frame concerned a correspondingly colored To keep plastic profile as a total part in stock. In the composite profile according to the invention This is no longer necessary because of its modular design Here only according to color differently different side parts are stored have to.
Auch erübrigt sich bei dem modularen Aufbau des erfindungsgemäßen Verbundprofils, daß das Metall-Hohlprofil (Stützträgerprofil) nicht mehr, wie bislang oftmals, in das äußere Kunststoffteil eingeschoben werden muß, da eine seitliche Kunststoffbeplankung erfolgt.Also Needless in the modular structure of the composite profile according to the invention, that the metal hollow profile (Support beam profile) no more, as previously often inserted into the outer plastic part must become, because a lateral plastic planking takes place.
Durch diese aufgezeigten Vorteile lassen sich gerade bezüglich der Lagerhaltung erhebliche Einsparung sowohl an Lagerplatz wie auch an Lagervolumen und damit deutliche Kostenvorteile gegenüber dem Fall einer Verwendung bekannter Rahmenprofile erreichen.By These advantages shown can be straight with respect to the Warehousing considerable savings in both storage space as well on storage volume and thus significant cost advantages over the Case of using known frame profiles.
Die Halterungsvorsprünge lassen sich ebenso wie die Formaufnahmen am Metall-Halteprofil in allen für eine formschlüssige und spielfreie Befestigung von Kunststoffteil und Metall-Hohlprofil aneinander geeigneten Formgebungen ausführen, wobei dem Fachmann hierzu eine Vielzahl von Gestaltungen bekannt sind. Besonders bevorzugt werden die Halterungsvorsprünge jedoch in Form von Raststegen und die Formaufnahmen in Form von Rastnuten ausgebildet. Dabei kann die Verrastung so vorgesehen sein, daß es sich um eine wieder lösbare oder um eine unlösbare Verrastung handelt.The holding projections can be as well as the mold holders on the metal holding profile in all for one positive and backlash-free attachment of plastic part and metal hollow profile perform suitable shapes, the skilled person for this purpose a variety of designs are known. Especially preferred become the support projections However, in the form of locking bars and the form of photographs in the form of Formed locking grooves. The locking can be provided in this way that it a detachable one or an insoluble one Latching acts.
Für eine unlösbare Verrastung werden die Raststege sowie die Rastnuten ganz besonders bevorzugt so ausgebildet, daß sie einen im wesentlichen schwalbenschwanzförmigen Querschnitt aufweisen, wodurch sich sowohl eine spielfreie, wie auch eine sehr feste Verbindung zwischen Metall-Hohlprofil und Kunststoffteil erreichen läßt.For an indissoluble locking the latching webs and the locking grooves are very particularly preferred so educated that she have a substantially dovetail-shaped cross-section, resulting in both a play-free, as well as a very solid connection can reach between metal hollow section and plastic part.
In besonders günstiger Ausgestaltung der Erfindung werden die Kunststoffteile als Kunststoffschalen ausgeführt.In especially cheaper Embodiment of the invention, the plastic parts as plastic trays executed.
Die Kunststoffteile können aus jedem für ihre Verwendung geeigneten Kunststoffmaterial ausgebildet sein, wobei sie besonders bevorzugt aus geschäumtem Kunststoff bestehen. Ganz besonders vorteilhaft ist es, wenn die Kunststoffteile aus Hart-PVC gefertigt sind, was zu einer besonders stabilen Ausgestaltung der Kunststoffteile führt.The Plastic parts can from each one for their use be made of suitable plastic material wherein they are particularly preferably made of foamed plastic. It is particularly advantageous if the plastic parts made of hard PVC are made, resulting in a particularly stable design of the Plastic parts leads.
Weiter ist es bei der Erfindung bevorzugt, wenn die Kunststoffteile identisch ausgebildet sind, wodurch sich erneut Einsparungen in der Lagerhaltung ergeben.Further In the case of the invention it is preferred if the plastic parts are identical are formed, thereby again saving in storage result.
Das Metall-Hohlprofil des erfindungsgemäßen Verbundprofils kann aus jedem geeigneten Metall bestehen, so z. B. aus Baustahl. Besonders bevorzugt wird es jedoch aus Leichtmetall gefertigt, ganz besonders vorteilhafterweise aus Aluminium oder einer Aluminiumverbindung.The Metal hollow profile of the composite profile according to the invention may be made consist of any suitable metal, such. B. of mild steel. Especially however, it is preferably made of light metal, especially advantageously of aluminum or an aluminum compound.
Das erfindungsgemäße Verbundprofil führt insgesamt nicht nur zu einer ganz merklichen Einsparung in der Lagerhaltung, sondern es kann vom Verarbeiter am Einsatzort auch unschwer geschnitten, zusammengebaut und verschweißt werden, so daß es hierfür keinerlei neuer Verarbeitungstechniken bedarf.The Composite profile according to the invention leads overall not only to a noticeable saving in storage, but it can also easily cut by the processor on site, assembled and welded be so that it therefor no new processing techniques needed.
