Description

Die Erfindung betrifft eine Endkappe zum Verschließen eines offenen Stirnbereichs eines mehrere Hohlkammern aufweisenden extrudierten Kunststoffprofils sowie deren Verwendung. Die Endkappe dient insbesondere dem Verschließen eines offenen Stirnbereichs eines Flügel- oder Stulpprofils eines Stulpfensters bzw. einer Stulptür.The invention relates to an end cap for closing an open end region of a plurality of hollow chambers having extruded plastic profile and their use. The end cap is used in particular for closing an open end region of a wing or Stulpprofils a Stulfensters or a sculpting door.

Technisches GebietTechnical area

Stulpfenster bzw. -türen sind Fenster bzw. Türen mit wenigstens zwei Flügeln ohne zwischenliegenden, vertikal verlaufenden Pfosten. Der zuerst zu öffnende Flügel, der sog. Gehflügel, schlägt beim Schließen dabei an den anderen, den sog. Lüftungs- oder Standflügel, an.Stulpfenster or doors are windows or doors with at least two wings without intermediate, vertically extending posts. The first wing to be opened, the so-called "grand piano", strikes against the other, the so-called ventilation or solid wing, when it closes.

Im Stulpbereich wird beim Standflügel zur Bildung des Anschlages für den Gehflügel üblicherweise ein sogenanntes Stulpprofil verwendet, das entweder mit einem gegebenenfalls beschnittenen Flügelrahmenprofil kombiniert wird oder selbst mit dem oberen und dem unteren horizontal verlaufenden Flügelrahmenprofil verschweißt wird. In jedem Fall sind die Stirnenden des Stulpprofils an seinen beiden Enden offen und werden üblicherweise durch eine Stulpendkappe verschlossen.In the forend area, a so-called cuff profile is usually used in the passive leaf to form the stop for the pedestrian wing, which is either combined with an optionally trimmed casement profile or even welded to the upper and lower horizontally extending casement profile. In any case, the front ends of the cuff profile are open at both ends and are usually closed by a cuff cap.

Bei bestimmten Fensterarten, insbesondere auch bei bestimmten Stulpfenster-Konstruktionen, wird eine sogenannte Falzwechselverschweißung durchgeführt, bei der zwei Hohlkammerprofile unterschiedlicher Querschnittsgeometrie im Gehrungsbereich miteinander verschweißt werden. Auch bei diesen Fenstern können im Gehrungsbereich offene Stirnenden eines der beiden Hohlkammerprofile entstehen, die mit einer Endkappe verschlossen werden müssen.In certain types of windows, in particular also in certain curb-window constructions, a so-called Falzwechselverschweißung is performed in which two hollow sections of different cross-sectional geometry in the miter area are welded together. Even with these windows open ends of one of the two hollow chamber profiles can be created in the miter area, which must be closed with an end cap.

Stand der TechnikState of the art

Gattungsgemäße Endkappen weisen typischerweise Klemmnasen, -laschen oder -stege auf, die eine Führung und eine gewisse reibschlüssige Verankerung der Endkappen in den offenen Enden des jeweiligen Hohlkammerprofils ermöglichen. Diese Art der klemmenden Befestigung der Endkappen reicht aber in der Praxis nicht als alleinige Befestigung aus. Daher werden solche Endkappen häufig mit dem offenen Stirnbereich eines Hohlkammerprofils z. B. mit PVC-Kleber oder mit Silikon verklebt. Zumindest bis zum Abbinden oder Aushärten des Klebers muss die Endkappe aber mechanisch am Hohlkammerprofil fixiert werden. Zudem ist mit dem Kleben ein zusätzlicher Arbeitsschritt verbunden.Generic end caps typically have clamping lugs, lugs or webs, which allow a guide and a certain frictional anchoring of the end caps in the open ends of the respective hollow chamber profile. However, this type of clamping attachment of the end caps is not sufficient in practice as a sole attachment. Therefore, such end caps are often with the open end region of a hollow chamber profile z. B. glued with PVC adhesive or with silicone. At least until the adhesive cures or sets, however, the end cap must be mechanically fixed to the hollow chamber profile. In addition, an additional step is connected with the gluing.

Aus der EP 2 274 493 B1 und der EP 1 947 283 A2 sind Endkappen zum Verschließen eines offenen Stirnbereichs eines mehrere Hohlkammern aufweisenden extrudierten Kunststoffprofils bekannt, bei denen zur Montage der Endkappen Schrauben eingesetzt werden, die in spezielle Schraubkanäle der angrenzenden Profile, nämlich des Stulpprofils bzw. des senkrecht dazu verlaufenden Flügelrahmenprofils, eingeschraubt werden. Hierzu müssen die entsprechenden Hohlkammerprofile jedoch spezielle Schraubkanäle aufweisen, die einen erheblichen Mehraufwand bei der Extrusion bedingen.From the EP 2 274 493 B1 and the EP 1 947 283 A2 End caps for closing an open end region of a plurality of hollow chambers having extruded plastic profile are known in which screws are used for mounting the end caps, which are screwed into special screw channels of the adjacent profiles, namely the Stulpprofils or perpendicular thereto wing frame profile. For this purpose, however, the corresponding hollow chamber profiles must have special screw channels, which cause a considerable overhead in the extrusion.

Aus der EP 2 689 086 B1 ist eine gattungsgemäße Endkappe zum Verschließen des offenen Endes des Stulpprofils bekannt, die mehrere Klemmelemente sowie ein dübelartiges Spreizelement aufweist, das durch Eindrehen z. B. einer Schraube spreizbar ist. Diese Stulpendkappe ist für Hohlkammerprofile ohne spezielle Schraubkanäle geeignet und hat sich grundsätzlich bewährt. Mit dem Eindrehen der Schraube ist auch hier ein zusätzlicher Arbeitsgang verbunden.From the EP 2 689 086 B1 is a generic end cap for closing the open end of the Stulpprofils known, which has a plurality of clamping elements and a dowel-like expansion element, which by screwing z. B. a screw is spreadable. This cuff cap is suitable for hollow chamber profiles without special screw channels and has proven itself in principle. By screwing in the screw an additional operation is connected here as well.

Aufgabetask

Aufgabe der Erfindung ist es daher, eine Endkappe und ein Verfahren zum Verschließen eines offenen Stirnbereichs eines mehrere Hohlkammern aufweisenden extrudierten Kunststoffprofils zur Verfügung zu stellen, ohne dass ein Verschrauben oder Verkleben der Endkappe notwendig ist.The object of the invention is therefore an end cap and a method for closing an open end region of a plurality Hollow chambers having extruded plastic profiles to provide, without screwing or gluing the end cap is necessary.

Darstellung der ErfindungPresentation of the invention

Die Erfindung löst diese Aufgabe durch eine Endkappe mit einem Kappen-Grundkörper aus Kunststoff und wenigstens einer Klemmlasche aus Metall, wobei die Klemmlasche Mittel zum Verkrallen in wenigstens einer Wandung wenigstens einer der Hohlkammern aufweist.The invention solves this problem by an end cap with a cap body made of plastic and at least one clamping tab made of metal, wherein the clamping tab has means for clawing in at least one wall of at least one of the hollow chambers.

Die erfindungsgemäße Klemmlasche steht bevorzugt etwa senkrecht vom Kappen-Grundkörper ab bzw. verläuft etwa in Längserstreckung des abzudeckenden Hohlkammerprofils und ist bevorzugt federelastisch ausgeführt, so dass die Klemmlasche mit den Mitteln zum Verkrallen unter entsprechender Vorspannung an einer der Innenwände oder einer der Innenseiten der Außenwände des Hohlkammerprofils anliegt. Diese Ausführung der Klemmlaschen und der Mittel zum Verkrallen aus Metall ermöglicht es, dass sich die Mittel zum Verkrallen beim Einsetzen der erfindungsgemäßen Endkappe in die offene Stirnseite der zu verschließenden Hohlkammerprofile so fest formschlüssig eindrücken, dass ein Herausziehen der Endkappe aus dem verschlossenen Endbereich des Hohlkammerprofils entweder gar nicht oder nur mit erheblichem Kraftaufwand möglich ist.The clamping flap according to the invention is preferably approximately perpendicular to the cap body or extends approximately in the longitudinal extent of the hollow chamber profile to be covered and is preferably designed resiliently, so that the clamping plate with the means for locking under appropriate bias on one of the inner walls or one of the inner sides of the outer walls of the Hollow chamber profile is applied. This embodiment of the clamping straps and the metal locking means makes it possible that the means for locking when inserting the end cap according to the invention in the open end of the hollow chamber profiles to be locked so firmly form-fitting impress that withdrawal of the end cap from the closed end portion of the hollow chamber profile either not possible at all or only with considerable effort.

Bevorzugt weist wenigstens eines der Mittel zum Verkrallen eine Schneide auf, die bei bestimmungsgemäßem Einsetzen der Endkappe in einem solchen Winkel zu der angrenzenden Hohlkammer Wandung verläuft, dass bei einem Herausziehen ein noch festeres formschlüssiges Verkrallen der Klemmlasche in der entsprechenden Hohlkammerwandung erfolgt.Preferably, at least one of the means for clawing on a cutting edge, which runs at an appropriate angle to the adjacent hollow chamber wall at the intended insertion of the end cap, that when pulling out an even firmer form-locking clawing of the clamping plate takes place in the corresponding Hohlkammerwandung.

Als Mittel zum Verkrallen in einer Wandung einer der Hohlkammern des zu verschließenden Hohlkammerprofils werden bevorzugt Krallzähne, insbesondere eine oder mehrere Schneiden aufweisende Krallzähne, in der wenigstens einen Klemmlasche aus Metall vorgesehen. Solche Schneiden aufweisenden Krallzähne können in einfacher Weise in die Klemmlaschen gestanzt werden.As means for clawing in a wall of one of the hollow chambers of the hollow chamber profile to be closed are preferably Krallzähne, in particular one or more cutting having Krallzähne, in the at least one clamping tab made of metal intended. Such cutting teeth Krallzähne can be easily stamped into the clamping tabs.

Bevorzugt ist die wenigstens eine erfindungsgemäße Klemmlasche aus Metall Bestandteil einer Federklammer, die einen Basisbereich und bevorzugt mehrere von dem Basisbereich etwa senkrecht abstehende Klemmlaschen mit jeweils wenigstens einem Krallzahn aufweist. Eine solche Federklammer kann beispielsweise beim Spritzgießen der erfindungsgemäßen Endkappe mit ihrem Basisbereich in das Kunststoffmaterial der Endkappe eingesetzt und somit formschlüssig verbunden werden.Preferably, the at least one metal clamping lug according to the invention is part of a spring clip which has a base region and preferably a plurality of clamping lugs protruding approximately perpendicularly from the base region and each having at least one toothed tooth. Such a spring clip can be used, for example, in the injection molding of the end cap according to the invention with its base portion in the plastic material of the end cap and thus positively connected.

Nach einer bevorzugten Ausführungsform der Erfindung weist der Basisbereich der Federklammer jedoch eine Durchbrechung auf, von der wenigstens eine Schneide absteht. Zugleich weist der Kappen-Grundkörper bevorzugt einen - bevorzugt sich verjüngenden - Befestigungsdorn auf, auf den die Federklammer mit ihrer Durchbrechung aufgeschoben wird. Die wenigstens eine Schneide der Durchbrechung der Federklammer schneidet dann in den Befestigungsdorn so ein, dass eine in Achsrichtung des Dorns feste, formschlüssige Verbindung zwischen Federklammer und Kappen-Grundkörper erfolgt.According to a preferred embodiment of the invention, however, the base portion of the spring clip on an opening, projects from the at least one cutting edge. At the same time, the cap base body preferably has a - preferably tapered - mounting pin on which the spring clip is pushed with its opening. The at least one cutting edge of the aperture of the spring clip then cuts into the fastening mandrel in such a way that a fixed, positive connection between the spring clip and the cap base body takes place in the axial direction of the mandrel.

Nach einer besonders bevorzugten Ausführungsform der Erfindung ist in dem Kappen-Grundkörper aus Kunststoff eine Vertiefung vorgesehen, in die die Federklammer beim Aufsetzen auf den Befestigungsdorn so eingreift, dass sie verdrehgesichert am Kappen-Grundkörper befestigt ist.According to a particularly preferred embodiment of the invention, a recess is provided in the cap base made of plastic, in which engages the spring clip when placed on the mounting mandrel so that it is secured against rotation on the cap base body.

Zusätzlich weist der Kappen-Grundkörper eine oder mehrere zusätzliche Klemmlaschen aus Kunststoff auf, die eine Führung beim Einsetzen der erfindungsgemäßen Endkappe in den offenen Stirnbereich des Hohlkammerprofils ermöglichen. Zur weiteren Erhöhung der Torsionssteifigkeit der Verbindung zwischen der erfindungsgemäßen Endkappe und dem Hohlkammerprofil kann das offene Ende des Hohlkammerprofils so beschnitten bzw. befräst werden, dass sich die erfindungsgemäße Endkappe mit einer oder mehrerer ihrer seitlichen Kanten an entsprechenden Vorsprüngen des Stirnbereichs des Hohlkammerprofils abstützt.In addition, the cap base body on one or more additional plastic clamping straps, which allow a guide during insertion of the end cap according to the invention in the open end region of the hollow chamber profile. To further increase the torsional rigidity of the connection between the end cap according to the invention and the hollow chamber profile, the open end of the hollow chamber profile can be trimmed or milled so that the end cap according to the invention with one or more several of its lateral edges are supported on corresponding projections of the end region of the hollow chamber profile.

Die erfindungsgemäße Endkappe kann beispielsweise als Stulpendkappe oder als Endkappe zum Verschließen des offenen Stirnbereichs eines horizontal verlaufenden Flügelprofils im Stulpbereich eines Stulpfensters eingesetzt werden, eignet sich prinzipiell aber auch zum Verschließen anderer offener Stirnbereiche von aus Kunststoff extrudierten Hohlkammerprofilen. Auch wenn bei der erfindungsgemäßen Endkappe ein zusätzliches Verschrauben oder Verkleben nicht mehr notwendig ist, liegt dieses dennoch im Schutzbereich der vorliegenden Erfindung.The end cap according to the invention can be used, for example, as a cuff cap or as an end cap for closing the open end region of a horizontally extending airfoil in the cuff area of a curb window, but is in principle also suitable for closing other open end regions of extruded hollow chamber profiles. Even if an additional screwing or gluing is no longer necessary in the end cap according to the invention, this is still within the scope of the present invention.

Bester Weg zur Ausführung der ErfindungBest way to carry out the invention

Die in diesem Ausführungsbeispiel der Erfindung erläuterte Endkappe 1 besteht aus dem Kappen-Grundkörper 2 und der Federklammer 6 aus Federstahl. Der Kappen-Grundkörper 2 wird aus PVC im Spritzgussverfahren hergestellt und dient - wie in Fig. 5 zu erkennen - zum Verschließen der offenen Stirnfläche 14 des Flügelrahmenprofils 12 eines Stulpfensterflügels.The illustrated in this embodiment of the invention end cap 1 consists of the cap body 2 and the spring clip 6 made of spring steel. The cap body 2 is made of PVC by injection molding and serves - as in Fig. 5 to recognize - to close the open end face 14 of the sash frame profile 12 of a cuff window sash.

Der Kappen-Grundkörper 2 weist auf seiner der offenen Stirnfläche 14 zugewandten Unterseite an sich bekannte Führungslaschen 4, 4', 4" auf, die etwa senkrecht von dieser Unterseite abstehen und zur Führung in den offenen Hohlkammern des Flügelrahmenprofils 12 dienen. Zur Befestigung der Federklammer 6 am Kappen-Grundkörper 2 weist der Kappen-Grundkörper 2 einen sich verjüngenden Befestigungsdorn 3 auf, der senkrecht von der Unterseite des Kappen-Grundkörpers 2 absteht.The cap body 2 has on its underside facing the open end face 14 known per se guide tabs 4, 4 ', 4 ", which protrude approximately perpendicularly from this underside and serve to guide in the open hollow chambers of the sash profile 12. To attach the spring clip 6 to the cap base 2, the cap base 2 has a tapered attachment pin 3 extending perpendicularly from the underside of the cap body 2.

Die Federklammer 6 wird durch Stanzen aus Federstahl hergestellt und weist im Wesentlichen den Basisbereich 22 sowie zwei seitlich und etwa senkrecht vom Basisbereich 22 abstehende Krall-Laschen 7, 7' auf. In Fig. 1 sind an jeder der beiden Krall-Laschen 7, 7' ebenfalls durch Stanzen erzeugte Krallzähne 8 zu erkennen, die scharfe Schneiden aufweisen und ein festes formschlüssiges Verzahnen in den Kammern 20, 21 des Flügelrahmenprofils 12 ermöglichen.The spring clip 6 is produced by stamping from spring steel and essentially has the base region 22 and two laterally and approximately perpendicularly protruding from the base region 22 Krall tabs 7, 7 '. In Fig. 1 can be seen on each of the two Krall tabs 7, 7 'also produced by punching Krallzähne 8, which have sharp edges and allow a solid positive interlocking teeth in the chambers 20, 21 of the sash profile 12.

Der Federklammer 6 weist an ihrem Basisbereich 22 eine Durchbrechung 23 auf, die zugleich die beiden Schneiden 9 bildet. Beim Aufschieben der Federklammer 6 auf den Befestigungsdorn 3 des Kappen-Grundkörpers 2 - wie in Fig. 1 und 2 dargestellt - entsteht eine in Achsrichtung feste Klemmverbindung, so dass ein axiales Lösen der Federklammer 6 vom Kappen-Grundkörper 2 verhindert wird. Zugleich wird ein Verdrehen der Federklammer 6 gegenüber dem Kappen-Grundkörper 2 dadurch verhindert, dass der Basisbereich 22 der Federklammer 6 in die Vertiefung 5 des Kappen-Grundkörpers 2 eingreift (Fig. 3 und 4).The spring clip 6 has at its base portion 22 an opening 23 which forms the two cutting edges 9 at the same time. When pushing the spring clip 6 on the mounting pin 3 of the cap body 2 - as in Fig. 1 and 2 shown - creates a fixed clamping in the axial direction, so that an axial release of the spring clip 6 is prevented by the cap body 2. At the same time a rotation of the spring clip 6 relative to the cap body 2 is prevented by the base portion 22 of the spring clip 6 engages in the recess 5 of the cap body 2 ( 3 and 4 ).

In Fig. 5 ist der obere, von der Rauminnenseite gesehen linke Gehrungsbereich eines Stulpfensters mit dem oberen waagerecht verlaufenden Flügelrahmenprofil 12 und dem vertikal im Stulpbereich verlaufenden Stulp-Grundprofil 15 dargestellt. Mit Ausnahme des innenliegenden Flügelüberschlags sind das Flügelrahmenprofil 12 und das Stulp-Grundprofil 15 im Querschnitt weitgehend identisch. Das Stulp-Grundprofil 15 weist anstelle eines Flügelüberschlags die Dichtung-Anlagefläche 16 auf, an die der sogenannte Gehflügel des Stulpfensters im vertikalen Bereich über die innere Anschlagdichtung anliegt. Wie in Fig. 5 gut zu erkennen, wird der beim Verschweißen im Gehrungsbereich 18 überstehende Teil des Flügelüberschlags des Flügelrahmenprofils 12 nach dem Verschweißen abgefräst, wobei von der Innensichtfläche 13 des Flügelrahmenprofils 12 eine schmale Kante 19 geringfügig gegenüber der Fräsung 17 übersteht.In Fig. 5 is the upper, viewed from the inside of the room left miter area of a custard window with the upper horizontally extending sash profile 12 and the vertical extending in the forend area Stulp-base profile 15 is shown. With the exception of the inner sash overlap the sash profile 12 and the forend basic profile 15 in cross section are substantially identical. The forend base profile 15 has, instead of a wing flap, the sealing contact surface 16, to which the so-called wing of the window Stulfensters in the vertical area over the inner stop seal. As in Fig. 5 can be clearly seen, the protruding during welding in the miter section 18 part of the wing flashover of the sash frame profile 12 is milled after welding, with a narrow edge 19 of the inner visible surface 13 of the sash frame profile 12 slightly protrudes from the milling 17.

In die so vorbereitete offene Stirnfläche 14 des Flügelrahmenprofils 12 wird anschließend die fertig montierte Endkappe 1 eingesetzt, wobei sich die Krallzähne 8 der beiden Krall-Laschen 7, 7' in die Innenwände der beiden Kammern 20, 21 des Flügelrahmenprofils 12 so verkrallen, dass die Endkappe 1 nur mit erheblichen Auszugskräften wieder entfernt werden kann.In the thus prepared open end face 14 of the sash profile 12, the fully assembled end cap 1 is then used, with the Krallzähne 8 of the two Krall tabs 7, 7 'in the inner walls of the two chambers 20, 21 of the sash profile 12 such a claw that the End cap 1 can only be removed again with considerable pull-out forces.

Die in Fig. 5 links verlaufende Kante des Kappen-Grundkörpers 2 liegt bei bestimmungsgemäßer Montage der Endkappe 1 auf voller Länge an der vorstehenden Kante 19 des Flügelrahmenprofils 12 an, so dass sich zusammen mit den Führungslaschen 4, 4', 4" eine relativ hohe Torsionsfestigkeit ergibt.In the Fig. 5 left-running edge of the cap base body 2 is when properly mounted on the end cap 1 full length on the protruding edge 19 of the sash profile 12, so that together with the guide plates 4, 4 ', 4 "results in a relatively high torsional strength.

Bei dem in den Figuren dargestellten Ausführungsbeispiel der erfindungsgemäßen Endkappe 1 ist neben dem Kappen-Grundkörper 2 eine von diesem senkrecht abstehende Dichtungs-Anlagefläche 10 vorgesehen, die die Dichtungs-Anlagefläche 16 des Stulp-Grundprofils 15 nach oben hin fortsetzt und in der leicht abgewinkelten Zunge 11 endet.In the embodiment of the end cap 1 according to the invention shown in the figures, in addition to the cap body 2, a vertically projecting sealing contact surface 10 is provided which continues the sealing abutment surface 16 of the forend base profile 15 upwards and in the slightly angled tongue 11 ends.
