Abstract

The connection has a shaft (14) including a rectangular cross-section, and inserted in a frame hollow profile. An inclined plane (16) extends corresponding to a bevel of the hollow profile. The inclined plane is terminated, welded or adhered to the shaft. A tensioning wedge (20) is braced to a strut part (22) of a rectangular area of the shaft. The tensioning wedge twists the shaft in the hollow profile. An expansion device is driven by a drive section (26) that moves along a transverse direction of the shaft. The expansion device is movable along a longitudinal direction of the shaft.

Description

Die Erfindung betrifft einen Eckverbinder für Tür- und Fensterrahmen, mit einem im Querschnitt rechteckigen Schaft zum Einschieben in ein auf Gehrung geschnittenes Rahmen-Hohlprofil und einer den Schaft abschließenden, verschweißbaren oder verklebbaren, entsprechend der Gehrung des Hohlprofils verlaufenden Schrägfläche sowie einer ein Spreizteil von einer der Rechteckflächen des Schafts abspreizenden Spreizvorrichtung zum Verspannen des Schafts im Hohlprofil.The invention relates to a corner connector for door and window frames, with a rectangular cross-section shank for insertion into a mitered frame hollow section and the shaft final, weldable or glued, according to the miter of the hollow profile extending inclined surface and a spreading of a the rectangular surfaces of the shaft spreading spreading device for clamping the shaft in the hollow profile.

Derartige Eckverbinder sind in zahlreichen Ausführungsformen bekannt. Viele der bekannten Ausführungsformen weisen eine in Längsrichtung des Schafts verschiebbare oder bewegliche Keilvorrichtung auf, die zu einer Verspreizung des Schafts führt und diesen im Hohlprofil verspannt.Such corner connectors are known in numerous embodiments. Many of the known embodiments have a slidable or movable in the longitudinal direction of the shaft wedge device, which leads to a spreading of the shaft and this clamped in the hollow profile.

Nach der DE 89 10 401 U1 des Anmelders wird ein Spreizkeil mithilfe einer von der Schrägfläche her eingeschraubten Schraube über eine Schrägfläche des Schafts herangezogen. Durch die Bewegung über die Keilfläche steigt der Spreizkeil an, so dass er sich im Inneren des Hohlprofils verspannt. Dabei bildet der Keil ein Spreizteil, das den Querschnitt des Eckverbinders vergrössert und dadurch die Verspannung erreicht. Die DE 91 13 235 U1 zeigt einen Eckverbinder, der ebenfalls einen Keil als Spreizteil aufweist, jedoch wird dieser nicht mithilfe einer Schraube, sondern einer an den Keil direkt angeformten Zunge in den Eckverbinder hineingeschoben oder aus diesem herausgezogen.After DE 89 10 401 U1 An expanding wedge is used by the applicant by means of a screw screwed in from the inclined surface over an inclined surface of the shank. As a result of the movement over the wedge surface, the expanding wedge increases, so that it braces in the interior of the hollow profile. In this case, the wedge forms a spreading part, which increases the cross-section of the corner connector and thereby reaches the tension. The DE 91 13 235 U1 shows a corner connector, which also has a wedge as a spreading, but this is not pushed by means of a screw, but one of the wedge directly molded tongue in the corner connector or pulled out of this.

In beiden Fällen reibt das Spreizteil unmittelbar an der Innenfläche des Hohlprofils. Besteht dieses aus Kunststoff, so ist in der Regel ein metallisches Verstärkungsprofil eingeschoben. Diese Verstärkungsprofile, zumeist aus Stahl, haben nicht immer eine glatte Innenfläche, so dass unter Umständen sehr unterschiedliche Reibungskoeffizienten eine Rolle spielen und zumindest anhand der ausgeübten Zug- oder Druckkraft nicht festgestellt werden kann, ob die Verspannung vollständig erfolgt ist.In both cases, the spreader rubs directly against the inner surface of the hollow profile. Is this made of plastic, so a metallic reinforcing profile is inserted in the rule. These reinforcing profiles, usually made of steel, do not always have a smooth inner surface, so that possibly very different coefficients of friction play a role and at least on the basis of the applied tensile or compressive force can not be determined whether the bracing has been completed.

Daher wird in der EP 1 054 130 B1 des Anmelders eine Lösung beschrieben, bei der zwischen dem als Keil ausgebildeten Spreizteil und der Innenfläche des Hohlprofils eine Druckplatte liegt, die durch das Spreizteil nach außen gedrückt wird und gewährleistet, dass der Keil bei seiner Längsverschiebung auf der stets gleichen Innenfläche der Druckplatte verschoben wird, so dass die rechte Zug- oder Druckkraft, mit der der Keil verschoben worden ist, stets ein Maß für die erreichte Verspannung ist.Therefore, in the EP 1 054 130 B1 the Applicant described a solution in which between the wedge-shaped expansion part and the inner surface of the hollow profile is a pressure plate which is pressed by the expansion part to the outside and ensures that the wedge is displaced in its longitudinal displacement on the always same inner surface of the printing plate, so that the right tensile or compressive force with which the wedge has been displaced, is always a measure of the tension achieved.

Herkömmliche Spreizvorrichtungen weisen bei den beschriebenen Ausführungsformen einem in Längsrichtung des Schafts verschiebbaren Keil auf, der aus dem Hohlprofil herausgezogen oder in dieses hineingeschoben werden muß, um die Keilwirkung zu erzielen. In jedem Fall erfolgt die Verspannung durch Längsverschiebung in dem Schaft.Conventional spreaders have in the described embodiments a displaceable in the longitudinal direction of the shaft wedge, which must be pulled out of the hollow profile or pushed into this, in order to achieve the wedge effect. In any case, the tension takes place by longitudinal displacement in the shaft.

Sowohl beim Hereindrücken als auch beim Herausziehen der Keilvorrichtung in Bezug auf den Eckverbinder ergibt sich das Problem, dass für ein wie auch immer geartetes Werkzeug kein geeigneter Abstützpunkt vorhanden ist. Bei Abstützung auf der Schrägfläche des Eckverbinders besteht die Gefahr, dass der Eckverbinder in das Hohlprofil hineinrutscht.Both when pushing in and when pulling out of the wedge device with respect to the corner connector, the problem arises that for any kind of tool no suitable support point is present. When supported on the inclined surface of the corner connector there is a risk that the corner connector slips into the hollow profile.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Eckverbinder der eingangs genannten Art zu schaffen, der die Möglichkeit einer sicheren Abstützung eines Zugwerkzeugs zum Herausziehen der Spannvorrichtung auf dem Eckverbinder bietet.The invention is therefore an object of the invention to provide a corner joint of the type mentioned above, which offers the possibility of a secure support of a pulling tool for pulling out the clamping device on the corner connector.

Zur Lösung dieser Aufgabe ist der erfindungsgemäße Eckverbinder dadurch gekennzeichnet, dass eine in Längsrichtung des Schafts verschiebbare Spreizvorrichtung vorgesehen ist, die durch einen in Querrichtung des Schafts bewegliches Antriebselement antreibbar ist.To solve this problem, the corner connector according to the invention is characterized in that a displaceable in the longitudinal direction of the shaft spreading device is provided, which is drivable by a movable in the transverse direction of the shaft drive element.

Die Längsbewegung der Spannvorrichtung wird dadurch ausgelöst, dass ein in Querrichtung des Eckverbinders bewegliches und insbesondere aus diesem herausziehbares, eine Keilfläche aufweisendes Element betätigt wird.The longitudinal movement of the tensioning device is triggered by a movable in the transverse direction of the corner connector and in particular from this pull-out, a wedge surface exhibiting element is actuated.

Dies hat den Vorteil, dass ein Zugwerkzeug verwendet werden kann, das auf dem Hohlprofil abgestützt werden kann.This has the advantage that a pulling tool can be used, which can be supported on the hollow profile.

Das Keilelement kann sowohl nach oben als auch zu den Seiten herausgezogen werden, da die Verschiebung quer zur Längsachse des Schafts in eine Verschiebung der Spreizvorrichtung, gebildet durch einen Keil oder dergleichen, umgesetzt wird. Vorzugsweise wird das Keilelement, mit dem die Verspannung des Eckverbinders bewirkt wird, durch eine Ausnehmung in der Schrägfläche nach oben herausgezogen, da diese, im Gegensatz zu den Seitenflächen des Eckverbinders, auch während des Verspannungsvorgangs noch frei zugänglich bleibt.The wedge element can be pulled out both upwards and to the sides, since the displacement transversely to the longitudinal axis of the shaft is converted into a displacement of the spreading device, formed by a wedge or the like. Preferably, the wedge element, with which the tension of the corner connector is effected, pulled out through a recess in the inclined surface upwards, as this, in contrast to the side surfaces of the corner connector, remains freely accessible during the bracing operation.

Im folgenden werden bevorzugte Ausführungsbeispiele der Erfindung anhand der beigefügten Zeichnung näher erläutert.

In the following preferred embodiments of the invention will be described with reference to the accompanying drawings.
Fig. 1

Mit der Bezugsziffer 10 ist in Fig. 1 und 2 ein Fenster-Hohlprofil, beispielsweise aus Kunststoff bezeichnet. Fig. 2 zeigt den Endbereich des Hohlprofils, der unter 45° auf Gehrung geschnitten ist. In dem Hohlprofil befindet sich ein Versteifungsprofil 12, beispielsweise ein aus Stahl bestehendes Vierkantprofil, wie es üblicherweise in Kunststoff-Hohlprofile eingeschoben wird. In das Versteifungsprofil 12 ist ein Eckverbinder eingeschoben, der einen an das Versteifungsprofil 12 angepaßten, also beispielsweise im Querschnitt rechtekkigen Schaft 14, der zum Gehrungsbereich des Kunststoff-Hohlprofils 10 hin in einer Schrägfläche 16 endet, die mit der Schrägfläche des Kunststoff-Hohlprofils 10 ausgerichtet wird.The reference numeral 10 is in Fig. 1 and 2 a window hollow profile, for example, called plastic. Fig. 2 shows the end of the hollow section, which is mitred at 45 °. In the hollow profile is a stiffening profile 12, for example, a steel existing square profile, as it is usually inserted in plastic hollow sections. In the stiffening profile 12, a corner connector is inserted, which adapted to the stiffening profile 12, ie, for example, in cross-section rechtkkigen shaft 14 which ends to the miter region of the plastic hollow section 10 in an inclined surface 16, which is aligned with the inclined surface of the plastic hollow section 10 becomes.

Der Schaft 14 gemäß Fig. 2 weist auf seiner Oberseite eine Keilfläche 18 auf, auf der ein Spannkeil 20 liegt, dessen Form dem aufgrund der Keilfläche 18 fehlenden Teil des Schafts 14 entspricht.The shaft 14 according to Fig. 2 has on its upper side a wedge surface 18 on which a clamping wedge 20 is located, the shape of which corresponds to the missing due to the wedge surface 18 part of the shaft 14.

Es ist erkennbar, dass eine Verschiebung des Keils 20 nach links in Fig. 2 dazu führen muß, dass der Keil 20 angehoben wird und damit eine Verspannung des Eckverbinders im Inneren des Versteifungsprofils 12 erfolgt.It can be seen that a displacement of the wedge 20 to the left in Fig. 2 must lead to the wedge 20 is raised and thus a strain of the corner connector takes place in the interior of the stiffening profile 12.

Nach dem eingangs genannten Gebrauchsmuster 91 13 235 U1 besitzt der Spannkeil, der dem vorliegenden Spannkeil 20 entspricht, eine aus dem Hohlprofil herausragende Zunge, über die der Spannkeil in das Innere des Eckverbinders hineingedrückt oder hineingeschlagen werden kann. Dadurch kann es leicht zu einer Verschiebung des Eckverbinders im Hohlprofil kommen.After the aforementioned utility model 91 13 235 U1 has the clamping wedge, which corresponds to the present clamping wedge 20, a protruding from the hollow profile tongue over which the clamping wedge can be pushed or pushed into the interior of the corner connector. This can easily lead to a displacement of the corner connector in the hollow profile.

Erfindungsgemäß erfolgt die Verschiebung des Spannkeils durch Kräfte, die, in bezug auf die Längsrichtung des Eckverbinders, neutral sind, das heißt, die quer zur Längsrichtung des Schafts gerichtet sind. Zu diesem Zweck weist der Eckverbinder in dem Bereich des vorderen, breiteren Endes des Spannkeils 20 eine Ausnehmung 24 auf. Diese Ausnehmung 24 in dem Schaft des Eckverbinders ist so angeordnet, dass sie ein Antriebselement aufnehmen kann, das eine Keilfläche zumindest auf der dem Spannkeil 20 zugewandten Seite aufweist, die mit 28 bezeichnet ist.According to the invention, the displacement of the clamping wedge by forces, which are, with respect to the longitudinal direction of the corner connector, neutral, that is, which are directed transversely to the longitudinal direction of the shaft. For this purpose, the corner connector in the region of the front, wider end of the clamping wedge 20 has a recess 24. This recess 24 in the shank of the corner connector is arranged so that it can receive a drive element which has a wedge surface at least on the clamping wedge 20 facing side, which is designated by 28.

Wenn nunmehr das Keilelement nach oben in Fig. 2 gezogen wird, drückt die Keilfläche 28 den Spannkeil 20 nach links in Fig. 2, so dass der Eckverbinder im Hohlprofil verspannt wird.Now if the wedge element up in Fig. 2 is pulled, the wedge surface 28 presses the clamping wedge 20 to the left in Fig. 2 , so that the corner connector is clamped in the hollow profile.

Zum Herausziehen des Antriebselements 26 eignen sich beispielsweise ein Werkzeug 30, das bei der dargestellten Ausführungsform als L-förmige Stange ausgebildet ist, die sich auf dem Eckverbinder auf dessen Oberseite abstützt und sich dazu eignet, das Antriebselement 26 nach oben herauszuziehen.To pull out the drive element 26, for example, a tool 30, which is formed in the illustrated embodiment as an L-shaped rod, which is supported on the corner connector on the top and is suitable to pull out the drive member 26 upwards.

Die Erfindung offenbart einen Eckverbinder, der die Möglichkeit bietet, eine Zugkraft, die quer zum Eckverbinder ausgeübt wird, in die Richtung längs zum Eckverbinder umzulenken. In der Regel wird es nur möglich sein, das Antriebselement, das diese Längsverschiebung bewirkt, über die Schrägfläche des Eckverbinders herauszuziehen. Grundsätzlich ist jedoch die Verspannung des Eckverbinders durch Zug in jede der vier Richtungen möglich.The invention discloses a corner connector which provides the ability to deflect a tensile force exerted transversely of the corner connector in the direction along the corner connector. In general, it will only be possible to extract the drive element that causes this longitudinal displacement over the inclined surface of the corner connector. Basically, however, the tension of the corner connector is possible by train in each of the four directions.

Die zusammenwirkenden Berührungsflächen des Spannkeils 20 und des diesen verschiebenden Keils 28 sind insoweit selbsthemmend, als eine einmal erreichte Position beim Verspannen nicht durch Zurückrutschen aufgegeben wird.The cooperating contact surfaces of the clamping wedge 20 and the wedge 28 displaced therefrom are self-locking insofar as a position once reached is not given up by slipping back during clamping.

In Betracht kommen beispielsweise Ratschenprofile oder dergleichen.For example, ratchet profiles or the like may be considered.
