Description
ECKVERBINDER AUS KUNSTSTOFFPLASTIC CORNER CONNECTORS
Die Erfindung betrifft einen Eckverbinder aus Kunststoff für Tür- oder Fensterrahmen aus Hohlprofilen, in die Versteifungs-Profile aus Metall eingeschoben sind, die mit Hilfe von Eckverbindern verbunden werden, welche Eckverbinder einen dem Innenquerschnitt der Versteifungs-Profile entsprechenden Außenquerschnitt und eine an den Gehrungswinkel des Rahmens angepaßte abgeschrägte Stirnfläche aufweisen, die durch einander kreuzende Nuten gegliedert ist.The invention relates to a plastic corner connector for door or window frames made of hollow profiles, into which metal reinforcing profiles are inserted, which are connected by means of corner connectors, which corner connectors have an outer cross-section corresponding to the inner cross-section of the reinforcing profiles and a beveled front surface adapted to the miter angle of the frame, which is structured by intersecting grooves.
Ein derartiger Eckverbinder ist aus der DE-OS 33 20 624 bekannt. Eckverbinder dieser Art werden zumeist für Türen oder großflächige Fenster aus Kunststoff-Hohlprofilen verwendet, in die zur Versteifung Versteifungs-Profile aus Metall eingeschoben werden. Während die Kunststoff-Profile an den Ecken auf Gehrung geschnitten und verhältnismäßt einfach verschweißt werden können, bereitet die Verbindung der aus Metall bestehenden Versteifungsprofile an den Ecken Schwierigkeiten. Ein Verschweißen ist wegen der erforderlichen hohen Schweißtemperaturen, die die Kunststoffprofile zerstören würden, naturgemäß nicht möglich. Eine Verbindung mit Eckstücken, Schrauben etc. würde Durchbrüche in der Wand der Kunststoffprofile erforderlich machen, die aus optischen Gründen unerwünscht sind. Es ist daher bekannc, in die Enden der metallischen Versteifungsprofile Eckverbinder einzuschieben, die den selben Gehrungswinkel wie die Kunststoffprofile aufweisen und gemeinsam mit diesem mit Hilfe eines SchweißSchwertes verschweißt werden können.A corner connector of this type is known from DE-OS 33 20 624. Corner connectors of this type are mostly used for doors or large windows made of hollow plastic profiles, into which metal reinforcement profiles are inserted for reinforcement. While the plastic profiles can be mitred at the corners and welded relatively easily, connecting the metal reinforcement profiles at the corners is difficult. Welding is naturally not possible due to the high welding temperatures required, which would destroy the plastic profiles. A connection with corner pieces, screws, etc. would require openings in the wall of the plastic profiles, which are undesirable for optical reasons. It is therefore known to insert corner connectors into the ends of the metal reinforcement profiles, which have the same miter angle as the plastic profiles and can be welded together with them using a welding sword.
Aus der eingangs genannten DE-OS ist es im übrigen bekannt, die zu verschweißenden Stirnflächen der Eckverbinder als gegliederte Oberfläche mit einander kreuzenden Nuten und zwischen diesen liegenden VorSprüngen auszuführen.From the DE-OS mentioned at the beginning it is also known that the end faces of the corner connectors to be welded should be designed as a structured surface with intersecting grooves and projections between them.

Die Vorsprünge schmelzen beim Schweißvorgang ab und füllen die benachbarten Nuten mehr oder weniger aus. Es entsteht eine relativ feste Verbindung, zu deren Festigkeit es nicht wesentlich ist, wie weit die Vorsprünge im einzelnen abgeschmolzen werden, so daß Herstellungstoleranzen ohne weiteres kompensiert werden können.The projections melt during the welding process and more or less fill the adjacent grooves. A relatively strong connection is created, the strength of which does not depend on how far the individual projections are melted, so that manufacturing tolerances can be easily compensated.
Ein Nachteil dieser bekannten Lösung ergibt sich daraus, daß die Eckverbindung spielfrei und fest in den Enden der Versteifungsprofile sitzen müssen, wenn der gewünschte Versteifungseffekt erreicht werden soll. Aufgrund der unterschiedlichen thermischen Eigenschaften von Kunststoff und Metall kann es daher bei Erwärmung zu Spannungen kommen, die zu einem Aufreißen der metallischen Versteifungsprofile führen.A disadvantage of this known solution is that the corner connection must be firmly seated in the ends of the stiffening profiles without play if the desired stiffening effect is to be achieved. Due to the different thermal properties of plastic and metal, tensions can arise when heated, which can lead to the metal stiffening profiles tearing open.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Eckverbinder der eingangs genannten Art zu schilf fen, der einerseits einen festen und spielfreien Sitz in dem Versteifungsprofil gewährleistet, andererseits einen gewissen Längs- und Radialausgleich bei auftretenden Überspannungen gestattet.The invention is therefore based on the object of developing a corner connector of the type mentioned at the beginning, which on the one hand ensures a firm and play-free fit in the stiffening profile, and on the other hand allows a certain longitudinal and radial compensation in the event of overtensions occurring.
Diese Aufgabe wird erfindungsgemäß bei einem Eckverbinder der eingangs genannten Art dadurch gelöst, daß der Eckverbinder auf der ümfangsflache Rippen, insbesondere aus weichelastischem Material aufweist.This object is achieved according to the invention in a corner connector of the type mentioned at the outset in that the corner connector has ribs on the peripheral surface, in particular made of soft elastic material.
Diese Rippen können radial gerichtete Spannungen dadurch aufnehmen, daß sie flachgedrückt werden. Ein gewisser Ausgleich in Längsrichtung ist durch Verformung der Rippen möglich.These ribs can absorb radially directed stresses by being flattened. A certain amount of compensation in the longitudinal direction is possible by deforming the ribs.
Die Rippen laufen vorzugsweise in Längsrichtung der Eckverbinder, also in Einschubrichtung in bezug auf die Versteifungsprofile. Sie können unmittelbar an die Eck-The ribs preferably run in the longitudinal direction of the corner connectors, i.e. in the insertion direction in relation to the stiffening profiles. They can be directly connected to the corner

Beide Formen können auch nebeneinander verwendet werden.connectors or as elastic strips, for example made of rubber, inserted into the grooves of the corner connectors. Both forms can also be used side by side.
Der Eckverbinder wird in den Versteifungsprofilen vorzugsweise durch einen Spreizdübel festgelegt, der von der Stirnfläche her eingeschraubt wird. Der eingeschobene Endbereich ist vorzugsweise durch längsgerichtete Trennschlitze in einzelne Segmente unterteilt, die durch den Spreizdübel gespreizt und gegen die Innenfläche der Versteifungsprofile gedrückt werden können. Diese rein kraftschlüssige Verbindung ist vorteilhaft im Interesse eines ggf. erforderlichen, geringfügigen Ausgleichs in Längsrichtung.The corner connector is preferably fixed in the stiffening profiles by means of an expansion dowel that is screwed in from the front face. The inserted end area is preferably divided into individual segments by longitudinal dividing slots, which can be spread by the expansion dowel and pressed against the inner surface of the stiffening profiles. This purely force-fit connection is advantageous in the interest of any necessary, minor compensation in the longitudinal direction.
Die zu verschweißende Stirnfläche weist einander kreuzende Nuten auf, deren Querschnitt ,edoch nicht rechteckig, sonder U-förmig ausgerundet ist. Die Nuten können auch keilförmig und am Grund ausgerundet sein. Dadurch erweitert sich der Querschnitt der Vorsprünge in Richtung ihres Ansatzpunktes am Eckverbinder. Scharfkantige Ecken werden vermieden, so daß ein Abknicken der Vorsprünge aufgrund bestehender Kerbwirkungen ausgeschlossen ist. Beim Anschmelzen während eines Schweißvorganges nimmt die Querschnittsfläche der Vorsprünge mehr und mehr zu, so daß schließlich eine quasi massive Verbindung entsteht.The front surface to be welded has intersecting grooves whose cross-section is not rectangular, but rounded in a U-shape. The grooves can also be wedge-shaped and rounded at the base. This widens the cross-section of the projections in the direction of their attachment point on the corner connector. Sharp-edged corners are avoided, so that the projections cannot bend due to existing notch effects. When melting during a welding process, the cross-sectional area of the projections increases more and more, so that a quasi-solid connection is finally created.
Im folgenden werden bevorzugte Ausführungsbeispiele der Erfindung anhand der beigefügten Zeichnung näher erläutert.In the following, preferred embodiments of the invention are explained in more detail with reference to the accompanying drawings.

Fig. 3 ist ein Querschnitt durch eine andere Ausführungsform eines Eckverbinders .Fig. 3 is a cross-section through another embodiment of a corner connector.
Fig. 1 zeigt ein hohles Kunststoffprofil 10, wie es üblicherweise für Tür- und Fensterrahmen verwendet wird. Das KunstsLoffprofil 10 weist unter anderem einen nicht gezeigten, rechteckigen Hohlraum auf, in den ein rechteckiges Versteifungsprofil 12 aus Metall eingeschoben wird.Fig. 1 shows a hollow plastic profile 10, as is usually used for door and window frames. The plastic profile 10 has, among other things, a rectangular cavity (not shown) into which a rectangular stiffening profile 12 made of metal is inserted.
In den Innenraum des Versteifungsprofils 12 wird ein Eckverbinder 14 eingesetzt, der einen im Querschnitt dem Innenquerschnitt des Versteifungsprofils 12 entsprechenden Schaft 16 und eine schräge Stirnfläche 18 an einem Ende des Schaftes aufweist. Der Neigungswinkel der Stirnfläche 18 entspricht dem Gehrungswinkel· des Kunststoff prof ils 10 und beträgt daher zumeist 45°.A corner connector 14 is inserted into the interior of the stiffening profile 12, which has a shaft 16 with a cross-section corresponding to the inner cross-section of the stiffening profile 12 and an inclined front surface 18 at one end of the shaft. The angle of inclination of the front surface 18 corresponds to the miter angle of the plastic profile 10 and is therefore usually 45°.
Auf jeder der vier Außenfläche des Schaftes 16 befinden sich im dargestellten Beispiel drei längsgerichtete Rippen, die gegenüber der Oberfläche des Schaftes erhaben sind. Diese Rippen 20,22,24 können unmittelbar angesprit; sein, wie Fig. 1 und 2 zeigen, jedoch können apcv eir besetzte, elastische Rippen verwendet werden, wie später erläutert werden soll.In the example shown, there are three longitudinal ribs on each of the four outer surfaces of the shaft 16, which are raised above the surface of the shaft. These ribs 20, 22, 24 can be directly molded on, as shown in Figs. 1 and 2, but filled , elastic ribs can be used, as will be explained later.
Wie Fig. 2 zeigt, ist der Schaft 16 als Hohlprofil ausge-As shown in Fig. 2, the shaft 16 is designed as a hollow profile.
bildet. Der von der Stirnfläche 18 abgewandte Endbereich ist an den vier Ecken durch achsparallele Trennschlitze 26 in vier Segmente 28,30,32,34 unterteilt. Die Segmente sind an ihrer Innenseite durch längsgerichtete Stege 36 mit einem hohlzylindrischen Profilbereich 38 verbunden, der in den vier Ecken des Schaftes ebenfalls durch längsgerichtete Trennschlitze geteilt ist. In dem hohlzylindrischen Profilbereich 38 liegt ein Spreizdübel 40, der in bekannter Weise mit Hilfe einer Schraube 42 gespreizt werden kann, die durch eine Ausnehmung 44 in der Stirnfläche 18 eintritt. Auf diese Weise wird der Eckverbinder 14 in dem Versteifungsprofil 12 verankert.The end region facing away from the front face 18 is divided into four segments 28, 30, 32, 34 at the four corners by axially parallel dividing slots 26. The segments are connected on their inside by longitudinal webs 36 to a hollow cylindrical profile region 38, which is also divided by longitudinal dividing slots in the four corners of the shaft. In the hollow cylindrical profile region 38 there is an expansion dowel 40 which can be expanded in a known manner using a screw 42 which enters through a recess 44 in the front face 18. In this way the corner connector 14 is anchored in the stiffening profile 12.
Die Stirnfläche 18 befindet sich auf einem Kopfstück 26, 5 das gegenüber dem Schaft 16 an allen vier Seiten nach außen vorspringt und in seinem Umri£ an das Versteifungsprofil 12 angepaßt ist. Die Stirnfläche 18 ist durch einander senkrecht schneidende Nuten 48,50 in rasterförmig angeordnete Vorsprünge 52 unterteilt. Die Nuten 48,50 laufen zu ihrem Grund hin leicht keilförmig zusammen und sind am Grund ausgerundet.The front surface 18 is located on a head piece 26, 5 which projects outwards on all four sides relative to the shaft 16 and is adapted in its outline to the stiffening profile 12. The front surface 18 is divided into projections 52 arranged in a grid pattern by grooves 48, 50 which intersect vertically with one another. The grooves 48, 50 converge slightly wedge-shaped towards their base and are rounded at the base.
Fig. 3 zeigt einen Querschnitt durch eine andere Ausführungsform eines Schafts 16 des Eckverbinders. In dieser Schnittdarstellung sind wiederum die einzelnen Segmente 28,30,32,34, die Stege 36 und der hohlzylindrische Profilbereich 38 erkennbar. Auf den einzelnen Segmenten befinder sich jeweils an den äußeren Rändern die bereits erwähnten, angeformten Rippen 20,24. Im Mittelbereich der einzelnen Segmente befindet sich dagegen anstelle der Rippe 22 eine «ingesetzte Rippe 54 aus weichelastischem Material, beispielsweise aus Gummi, die in einer nicht bezeichneten Nut in der Wandfläche des Schafts bzw. dem zugehörigen Steg 36 liegt. Derartige Rippen aus Gummi gestatten eine beträchtliche Verformung in Radialrichtung, und sie ermöglichen auch geringe Kriechbewegungen in Längsrichtung. BejFig. 3 shows a cross section through another embodiment of a shaft 16 of the corner connector. In this sectional view, the individual segments 28, 30, 32, 34, the webs 36 and the hollow cylindrical profile area 38 can be seen. The already mentioned molded ribs 20, 24 are located on the outer edges of the individual segments. In the middle area of the individual segments, however, instead of the rib 22, there is an inserted rib 54 made of soft elastic material, for example made of rubber, which lies in an undesignated groove in the wall surface of the shaft or the associated web 36. Such ribs made of rubber allow considerable deformation in the radial direction and they also enable slight creeping movements in the longitudinal direction.
äußeren Rippen 20,22 ist eine hohe Elastizität weniger bedeutsam, da dds einzelnen Segmente in diesem Bereich ohnehin nachgeben können, während im Mittelbereich, in dem sich die Rippe 54 befindet, die Spreizkraft des Spreizdübeis 40 unmittelbar einwirkt.For the outer ribs 20, 22, high elasticity is less important, since the individual segments in this area can give way anyway, while in the middle area, where the rib 54 is located, the spreading force of the spreading dowel 40 acts directly.
Die Rippen 54, die in Nuten des Eckverbinders eingeset-&tgr;&idiagr; sind und beispielsweise Gummiprofile sein können, können eine unterschiedliche Querschnittsform aufweisen. In Abweichung von Fig. 3 kommen insbesondere hinterschnittene Nuten und entsprechende Rippen 54 in Betracht. Die Rippen können trapezförmige, dreieckige, runde, rechteckige oder sonstige Querschnitte aufweisen.The ribs 54, which are inserted into grooves of the corner connector and can be rubber profiles, for example, can have a different cross-sectional shape. In deviation from Fig. 3, undercut grooves and corresponding ribs 54 are particularly suitable. The ribs can have trapezoidal, triangular, round, rectangular or other cross-sections.
