Description

Die vorliegende Erfindung betrifft einen Eckverbinder für Hohlprofilrahmen gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a corner connector for hollow profile frame according to the preamble of claim 1.

Derartige Eckverbinder werden dazu verwendet, die auf Gehrung geschnittenen Endabschnitte zweier Hohlprofile eines Rahmens, wie etwa eines Fenster- oder Türrahmens miteinander rechtwinklig zu verbinden. Der Eckverbinder umfasst zu diesem Zweck ein Winkelstück mit zwei Schenkeln, die sich jeweils in die Endabschnitte der zu verbindenden Hohlprofile einschieben und darin verankern oder verspannen lassen. Hierbei ist es erforderlich, die Hohlprofile präzise und mit der geeigneten Spannung zusammenzufügen. Einerseits soll die Verbindung die erforderliche Stabilität aufweisen, andererseits sind jedoch zu hohe Drücke oder Spannungen im Rahmen zu vermeiden, damit keine Beschädigungen auftreten.Such corner connectors are used to connect the mitered end portions of two hollow sections of a frame, such as a window or door frame at right angles to each other. The corner connector comprises for this purpose an elbow with two legs, each of which can be inserted into the end portions of the hollow sections to be connected and anchored or braced therein. In this case, it is necessary to assemble the hollow profiles precisely and with the appropriate tension. On the one hand, the connection should have the required stability, on the other hand, however, to avoid high pressures or stresses in the frame, so that no damage occurs.

Zum Verspannen des Winkelstücks in den Hohlprofilen existiert bereits eine größere Anzahl von Lösungen, wie beispielsweise das Verbinder-Winkelstück, das in DE 199 00 957 A1 des Anmelders vorgeschlagen wird. Hierbei werden keilförmige Endabschnitte des Schenkels auf diesem mittels Spannschrauben verspannt, so dass ein Herausziehen aus dem Hohlprofilen nicht mehr möglich ist. Diese Art von Winkelverbindern eignet sich insbesondere für Fenster- oder Türrahmen aus Kunststoff oder Aluminium.For bracing the elbow in the hollow sections already exists a larger number of solutions, such as the connector elbow, in DE 199 00 957 A1 proposed by the applicant. Here, wedge-shaped end portions of the leg are braced on this by means of clamping screws, so that withdrawal from the hollow profiles is no longer possible. This type of angle connectors is particularly suitable for window or door frames made of plastic or aluminum.

Neuerdings werden Rahmenhohlprofile auch aus einem Materialgemisch hergestellt, das neben Kunststoff auch Holz oder Holzwerkstoffe enthält, wie etwa Holzmehl oder dergleichen. Dies ist aus Gründen einer Ressourcen schonenden und damit umweltfreundlichen Produktion erwünscht, da hier auch Recyclingstoffe zum Einsatz kommen können. Diese Materialien sind jedoch im Fenster- und Türenbau vergleichsweise neu und stellen in Bezug auf die Eckverbinder besondere Anforderungen. Solche Hohlprofile können mit hohen Drucklasten zusammengehalten werden, die von den bisher bekannten Eckverbindern, die eine Keilverbindung verwenden, nicht aufgebracht werden können. Es ist jedoch wichtig, die Last kontrolliert, d.h. mit einer vorgegebenen Kraft aufzubringen. Bei den bekannten Winkelverbindern ist dies nicht ohne weiteres möglich.Recently, hollow frame profiles are also made of a mixture of materials, which in addition to plastic also contains wood or wood-based materials, such as wood flour or the like. This is desirable for the sake of a resource-conserving and thus environmentally friendly production, since here also recycled materials can be used. However, these materials are comparatively new in window and door construction and make special demands with regard to the corner connectors. Such hollow profiles can be held together with high compressive loads, which can not be applied by the previously known corner connectors, which use a spline connection. However, it is important to control the load, ie to apply it with a given force. In the known angle connectors, this is not readily possible.

Ferner ist es erforderlich, die Hohlprofile während des Zusammenfügens ihrer Gehrungsschnittflächen möglichst genau aufeinander auszurichten, insbesondere auch seitlich zur Verspannrichtung, d.h. in einer Richtung, die senkrecht zu der Ebene steht, die von den Schenkeln des Winkelstücks aufgespannt wird.Furthermore, it is necessary to align the hollow sections as closely as possible during the assembly of their Miter cutting surfaces, especially laterally to the Verspannrichtung, i. in a direction perpendicular to the plane defined by the legs of the elbow.

Aufgabe der vorliegenden Erfindung ist es daher, einen Eckverbinder für Hohlprofilrahmen zu schaffen, der einfach und zuverlässig zu montieren ist und die Aufbringung hoher Drucklasten auf die Verbindungsstelle mit kontrolliertem Kraftaufwand zulässt. Eine weitere Aufgabe besteht in der Schaffung eines solchen Winkelverbinders, der die Hohlprofile des Rahmens selbst zentriert und miteinander verspannt.Object of the present invention is therefore to provide a corner joint for hollow profile frame, which is easy to install and reliable and allows the application of high pressure loads on the joint with controlled effort. Another object is to provide such an angle connector which centers the hollow sections of the frame itself and clamped together.

Diese Aufgabe wird erfindungsgemäß durch einen Eckverbinder mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a corner connector with the features of claim 1.

Erfindungsgemäß ist einer der beiden Schenkel des Winkelstücks an seinem Ende durch ein Spannstück ergänzt, das in der Verlängerung der Schenkelachse liegt und entlang dieser verschiebbar ist, so dass der Rest des Winkelstücks bzgl. des Spannstücks beweglich ist. Beide Schenkel weisen seitliche keilförmige Ausnehmungen auf, auf deren Keilflächen ein Keil derart aufliegt, dass seine Spitze zur Ecke des Winkelstücks hin orientiert ist. Die Keile können auf den Keilflächen gleitend verschoben werden, insbesondere in Richtung der Ecke. Der Keil, der im ersten Schenkel einliegt und im folgenden als erster Keil bezeichnet werden soll, ist an seiner Seite fest mit dem Spannstück verbunden, so dass er bei einer Relativbewegung des Spannstücks mit diesem mitgeführt wird und auf der Keilfläche gleitet.According to the invention, one of the two legs of the angle piece is supplemented at its end by a clamping piece which lies in the extension of the leg axis and is displaceable along the latter, so that the rest of the angle piece is movable relative to the clamping piece. Both legs have lateral wedge-shaped recesses, on the wedge surfaces of a wedge rests such that its tip is oriented towards the corner of the elbow. The wedges can be slid on the wedge surfaces, especially in the direction of the corner. The wedge, which rests in the first leg and will be referred to as the first wedge in the following, is firmly connected at its side with the clamping piece, so that it is carried along with a relative movement of the clamping piece with this and slides on the wedge surface.

Das Spannstück ist ebenso wie auch der verbleibende zweite Schenkel in den jeweiligen Endabschnitten des Hohlprofils verankerbar, z.B. durch Ankerschrauben. Eine Spannschraube ist von der Ecke des Winkelstücks her axial durch einen Kanal im ersten Schenkel geführt und erstreckt sich in das Spannstück hinein und ist in dieses eingeschraubt. Eine Drehung der Spannschraube wird somit in eine Verschiebebewegung des Spannstücks umgesetzt. Insbesondere lässt sich durch ein Anziehen der Spannschraube das Spannstück auf die Ecke zubewegen, so dass der erste Keil ebenfalls auf die Ecke zugleitet.The clamping piece is as well as the remaining second leg anchored in the respective end portions of the hollow profile, for example by anchor bolts. A clamping screw is guided axially from the corner of the angle ago by a channel in the first leg and extends into the clamping piece and is screwed into this. A rotation of the clamping screw is thus converted into a sliding movement of the clamping piece. In particular, can be by tightening the clamping screw the Move the clamping piece to the corner so that the first wedge also leads to the corner.

Aufgrund der Verankerung des Spannstücks und des zweiten Schenkels in den jeweiligen Endabschnitten der Hohlprofile findet somit auch ein Verspannen der Hohlprofile gegeneinander statt, indem diese an ihren Gehrungsschnittflächen aufeinanderstoßen. Auf die Spannschrauben können hohe, jedoch kontrollierte Kräfte mit Hilfe eines Drehmomentschlüssels ausgeübt werden, so dass durch Einstellung des Drehmoments auch der Druck gewählt wird, mit welchem die Hohlprofile gegeneinander gezogen werden. Eine zwischen den Hohlprofilen an den Gehrungsschnittflächen angebrachte Dichtung wird auf diese Weise mit einem bestimmten Druck zusammengepresst.Due to the anchoring of the clamping piece and the second leg in the respective end portions of the hollow profiles thus also takes place a distortion of the hollow profiles against each other by these collide at their Gehrungsschnittflächen. On the clamping screws high but controlled forces can be exercised by means of a torque wrench, so that by adjusting the torque and the pressure is selected, with which the hollow profiles are pulled against each other. An attached between the hollow sections of the Miter cutting surfaces seal is compressed in this way with a certain pressure.

Während des Verspannens werden die Schenkel des Winkelstücks aufgrund der Gleitbewegung der Keile auf die Ecke zu in seitlicher Richtung, d. h. quer zur Spannrichtung verbreitert. Es werden also nicht nur die Gehrungsschnittflächen der Hohlprofile gegeneinander gedrückt, sondern es findet auch ein seitliches Verspreizen der Schenkel innerhalb der Hohlprofile statt, das diesen zusätzlichen Halt gibt und ihre Position festlegt. Die den Keilen gegenüberliegende Seite des Winkelstücks dient hierbei als Referenzseite für die Positionierung im Hohlprofil, die stets von innen an dem Kanal im Profil zur Aufnahme des jeweiligen Schenkels anliegt.During the bracing, the legs of the elbow are due to the sliding movement of the wedges on the corner to the lateral direction, d. H. widens transversely to the clamping direction. So not only the miter cut surfaces of the hollow sections are pressed against each other, but there is also a lateral splaying of the legs held within the hollow sections, which gives this additional support and determines their position. The opposite side of the wedges of the elbow serves as a reference page for the positioning in the hollow profile, which always rests on the inside of the channel in profile for receiving the respective leg.

Bei der Montage wird beispielsweise zunächst der erste Schenkel zusammen mit dem Spannstück und dem ersten Keil in einen Hohlprofilendabschnitt eingeschoben, bis eine definierte Position erreicht ist, in der der Kopf der Spannschraube an der Ecke des Winkelstücks in einer Öffnung des Hohlprofils freiliegt. In dieser Position wird das Spannstück in seinem Hohlprofil verankert, beispielsweise durch Ankerschrauben, die von außen durch die Wand des Hohlprofils in das Spannstück eingedreht werden. Anschließend wird der Endabschnitt des verbleibenden Hohlprofilabschnitts auf den zweiten Schenkel mit dem zweiten Keil aufgeschoben, bis eine Innengewindebohrung im zweiten Schenkel mit einer entsprechenden Öffnung in der Außenwand des Hohlprofils fluchtet, so dass eine Ankerschraube darin eingedreht werden kann, die den zweiten Schenkel in seinem Hohlprofil verankert.During assembly, for example, first the first leg is inserted together with the clamping piece and the first wedge in a Hohlprofilendabschnitt until a defined position is reached, in which the head of the clamping screw is exposed at the corner of the elbow in an opening of the hollow profile. In this position, the clamping piece is anchored in its hollow profile, for example by anchor bolts, which are screwed from the outside through the wall of the hollow profile in the clamping piece. Subsequently, the end portion of the remaining hollow profile section is pushed onto the second leg with the second wedge until an internally threaded bore in the second leg is aligned with a corresponding opening in the outer wall of the hollow profile, so that an anchor screw can be screwed therein, the second leg in its hollow profile anchored.

Im folgenden wird die Spannschraube gedreht, so dass der erste Schenkel in Richtung des fest verankerten Spannstücks gezogen wird, bis die Gehrungsschnittflächen (über die darauf angebrachten Dichtungen) miteinander in Kontakt kommen. Gleichzeitig wird der mit dem Spannstück verbundene erste Keil mit dem darunter liegenden ersten Schenkel verspannt. Da beim Aufeinandertreffen der Gehrungsflächen eine seitliche Kraftkomponente quer zur Spannschraube auftritt, bewirkt diese eine seitliche Verschiebung des quer zur Spannschraube stehenden Hohlprofil-Endabschnitts und somit das Verspannen des zweiten Schenkels darin.In the following, the tightening screw is turned so that the first leg is pulled toward the firmly anchored tension piece until the miter cut surfaces (via the seals mounted thereon) come into contact with each other. At the same time the first wedge connected to the clamping piece is clamped to the underlying first leg. Since a lateral force component transversely to the clamping screw occurs when the miter surfaces meet, this causes a lateral displacement of the transverse to the clamping screw stationary hollow section end portion and thus the bracing of the second leg therein.

Gemäß einer besonderen Ausführungsform der vorliegenden Erfindung sind das Spannstück und der zweite Schenkel in den jeweiligen Endabschnitten durch Ankerschrauben verankerbar, die von außen durch die Wände der Endabschnitte in das Spannstück bzw. den zweiten Schenkel eingeschraubt sind.According to a particular embodiment of the present invention, the clamping piece and the second leg are anchored in the respective end portions by anchor bolts, which are screwed from the outside through the walls of the end portions in the clamping piece and the second leg.

Der in Fig. 1 dargestellte erfindungsgemäße Eckverbinder 10 dient zur Verbindung zweier Hohlprofile eines Rahmens, wie etwa eines Fenster- oder Türrahmens. Dieser Eckverbinder 10 ist jedoch nicht ausschließlich zum Einsatz an Fenster- oder Türrahmenprofilen geeignet, sondern eignet sich in gleicher Weise für Hohlprofilrahmen anderer Art, wie etwa zur Aufnahme von Photovoltaikmodulen oder dergleichen mehr.The in Fig. 1 shown corner connector 10 is used to connect two hollow sections of a frame, such as a window or door frame. However, this corner connector 10 is not suitable exclusively for use on window or door frame profiles, but is equally suitable for hollow profile frames of other types, such as for receiving photovoltaic modules or the like.

Der Eckverbinder 10 ist insgesamt L-förmig ausgebildet und umfasst ein Winkelstück 12 mit zwei Schenkeln 14,16, die im folgenden als erster Schenkel 14 und zweiter Schenkel 16 bezeichnet werden sollen. Die Schenkel 14, 16 stehen im rechten Winkel zueinander und sind zum Einschub in die zu verbindenden Endabschnitte zweier Hohlprofile des Rahmens vorgesehen.The corner connector 10 is formed overall L-shaped and includes an elbow 12 with two legs 14,16, which will be referred to in the following as the first leg 14 and second leg 16. The legs 14, 16 are at right angles to each other and are provided for insertion into the end portions to be joined two hollow sections of the frame.

Das Winkelstück 12 besteht aus Kunststoff, und die beiden Schenkel 14,16 sind einstückig an der Ecke 18 miteinander ausgeformt. An ihren Außenflächen, die dem jeweils anderen Schenkel abgewandt sind, weisen die Schenkel 14,16 Rippen 19 auf, die sich entlang des jeweiligen Schenkels 14,16 erstrecken.The angle piece 12 is made of plastic, and the two legs 14,16 are formed integrally with each other at the corner 18. On their outer surfaces, which are remote from the other leg, the legs 14,16 ribs 19 which extend along the respective leg 14,16.

Die Schenkel 14,16 haben im wesentlichen die gleiche Länge. Der erste Schenkel 14 auf der linken Seite in Fig. 1 weist an seinem freien Ende eine zentrale, etwa rechteckige Ausnehmung 20 auf. Sie dient zur Aufnahme eines Spannstücks 22, das entlang der Schenkelachse S des ersten Schenkels 14 in die Ausnehmung 20 einschiebbar ist. Dieser eingeschobene Zustand ist in Fig. 2 dargestellt.The legs 14,16 have substantially the same length. The first leg 14 on the left in Fig. 1 has at its free end a central, approximately rectangular recess 20. It serves to receive a clamping piece 22 which can be inserted along the leg axis S of the first leg 14 into the recess 20. This inserted state is in Fig. 2 shown.

Auf ihren Oberseiten in den Fig. 1 und 2 weisen die Schenkel 14,16 seitliche Ausfräsungen 24,26 auf. Diese erstrecken sich im wesentlichen entlang der jeweiligen Schenkelachse und sind etwa keilförmig ausgebildet, derart, dass die Tiefe der Ausfräsung 24,26 von der Ecke 18 her in Richtung der Enden der Schenkel 14,16 allmählich zunimmt. Der jeweilige Grund 28 der Ausfräsung bildet somit eine von der Ecke 18 her schräg abfallende Gleitfläche.On their tops in the Fig. 1 and 2 the legs 14,16 have lateral cutouts 24,26. These extend substantially along the respective leg axis and are approximately wedge-shaped, such that the depth of the cutout 24,26 gradually increases from the corner 18 in the direction of the ends of the legs 14,16. The respective bottom 28 of the cutout thus forms an inclined sloping from the corner 18 forth sliding surface.

Die Ausfräsungen 24,26 dienen zur Aufnahme von Keilen, nämlich eines ersten Keils 30, der in der Ausfräsung 24 im ersten Schenkel 14 einliegt, und eines zweiten Keils 32, der von der Ausfräsung 26 im zweiten Schenkel 16 aufgenommen wird. Der Querschnitt der Keile 30,32 ist im wesentlichen gleich. Beide Keile 30,32 weisen eine flache unterseitige Keilfläche zur Auflage auf dem jeweiligen Grund 28 der Ausfräsung 24,26 auf, sowie eine im Querschnitt leicht abgerundete Oberseite. Die Spitzen der Keile 30,32 weisen zur Ecke 18 hin, und ihr Keilwinkel entspricht demjenigen der Ausfräsungen 24,26, so dass die freien Oberseiten der Keile 30,32 im einliegenden Zustand in den Ausfräsungen 24,26 horizontal in einer Ebene liegen, parallel zu der Ebene, in der die gegenüberliegenden Seiten 34,36 der Schenkel 14,16 liegen, die sich in den Fig. 1 und 2 unten befinden.The recesses 24,26 serve to receive wedges, namely a first wedge 30, which rests in the cutout 24 in the first leg 14, and a second wedge 32 which is received by the cutout 26 in the second leg 16. The cross section of the wedges 30, 32 is essentially the same. Both wedges 30,32 have a flat underside wedge surface for resting on the respective bottom 28 of the cutout 24,26, and a slightly rounded in cross section top. The tips of the wedges 30,32 point towards the corner 18, and their wedge angle corresponds to that of the recesses 24,26, so that the free tops of the wedges 30,32 in the inserted state in the recesses 24,26 are horizontal in a plane parallel to the plane in which the opposite sides 34,36 of the legs 14,16 lie, which are in the Fig. 1 and 2 located below.

Der Keil 30 ist an seinem stumpfen, der Ecke 18 abgewandten Ende einstückig mit dem Spannstück 22 verbunden und seitlich (d. h. in den Fig. 1 und 2 oben) an das Spannstück 22 angeformt. Eine Verschiebung des Spannstücks 22 in die Ausnehmung 20 in Richtung der Ecke 18 führt somit zu einer entsprechenden Verschiebung des ersten Keils 30 in der Ausfräsung 24 im ersten Schenkel 14. Durch das Gleiten des ersten Keils 30 auf den Grund 28 der Ausfräsung 24 wandert der Keil 30 gleichzeitig nach oben in die Fig. 1 und 2, d. h. seitlich zur Verschieberichtung. Findet diese Verschiebung im eingesetzten Zustand des Eckverbinders 10 im Hohlprofil statt, wird durch die Bewegung des ersten Keils 30 der erste Schenkel 14 verbreitert und im entsprechenden Hohlprofil-Endabschnitt verspannt.The wedge 30 is integrally connected at its obtuse, the corner 18 opposite end with the clamping piece 22 and laterally (ie in the Fig. 1 and 2 above) to the clamping piece 22 is formed. A displacement of the clamping piece 22 in the recess 20 in the direction of the corner 18 thus results in a corresponding displacement of the first wedge 30 in the cutout 24 in the first leg 14. By sliding the first wedge 30 on the bottom 28 of the cutout 24 wedge the wedge 30 at the same time in the top Fig. 1 and 2 , ie laterally to the direction of displacement. If this displacement takes place in the inserted state of the corner connector 10 in the hollow profile, the first leg 14 is widened by the movement of the first wedge 30 and clamped in the corresponding hollow profile end section.

Dieses Verspannen lässt sich durch eine in den Fig. 1 und 2 nicht näher dargestellte Spannschraube erreichen, die von der Ecke 18 her durch einen Kanal 38 entlang der Schenkelachse S im ersten Schenkel 14 geführt ist und in diesem Kanal 38 frei drehbar ist. Mit ihrem Ende, das aus dem Kanal 38 in die Ausnehmung 20 ragt, ist die Spannschraube in das Spannstück 22 eingeschraubt. Durch ein Anziehen der Spannschraube lässt sich somit das Spannstück 22 in die entsprechende Ausnehmung 20 hineinziehen, so dass der erste Schenkel 14 auf die oben beschriebene Weise aufgespreizt und verspannt wird.This bracing can be through a in the Fig. 1 and 2 reach clamping screw not shown, which is guided from the corner 18 forth through a channel 38 along the leg axis S in the first leg 14 and is freely rotatable in this channel 38. With its end, which projects from the channel 38 into the recess 20, the clamping screw is screwed into the clamping piece 22. By tightening the clamping screw thus the clamping piece 22 can be pulled into the corresponding recess 20, so that the first leg 14 is spread and clamped in the manner described above.

Der zweite Keil 32, der im zweiten Schenkel 16 einliegt, weist an seinem stumpfen, der Ecke 18 abgewandten Ende einen seitlichen Zapfen 40 auf, der seitlich an dieses Ende angeformt ist und zur Keilspitze hinweist. Dieser Zapfen 40 ist dazu vorgesehen, vollständig in das freie Ende des zweiten Schenkels 16 aufgenommen zu werden und dort in ein Führungsloch zu gleiten, das in den Fig. 1 und 2 nicht näher dargestellt ist. Durch eine Verschiebebewegung des zweiten Keils 32 auf dem Grund 28 der Ausfräsung 26 wird der zweite Schenkel 16 im entsprechenden Hohlprofil-Endabschnitt verspannt. Dieses Verspannen geschieht automatisch bei Anziehen der vorstehend beschriebenen Spannschraube zur Bewegung des Spannstücks 22 in die Ausnehmung 20 des ersten Schenkels 14, so dass die Gehrungsflächen des Hohlprofils (siehe Fig. 3) zusammenstoßen und gegeneinander gedrückt werden.The second wedge 32, which rests in the second leg 16, has at its obtuse, the corner 18 remote from the end a lateral pin 40 which is laterally formed on this end and points to the wedge tip. This pin 40 is intended to be fully received in the free end of the second leg 16 and there to slide in a guide hole, which in the Fig. 1 and 2 not shown in detail. By a displacement movement of the second wedge 32 on the bottom 28 of the cutout 26 of the second leg 16 is braced in the corresponding hollow profile end portion. This tightening is done automatically when tightening the clamping screw described above for moving the clamping piece 22 into the recess 20 of the first leg 14, so that the miter surfaces of the hollow profile (see Fig. 3 ) collide and be pressed against each other.

Fig. 2 zeigt einen Zustand des Eckverbinders 10, in welchem das Spannstück 22 vollständig in die Ausnehmung 20 aufgenommen ist. Die Keile 30,32 liegen ferner vollständig in ihren Ausfräsungen 24,26 ein, so dass lediglich ihre Oberseiten und ihre Keilrücken an den Enden der Schenkel 14,16 freiliegen. Fig. 2 shows a state of the corner connector 10, in which the clamping piece 22 is completely received in the recess 20. The wedges 30,32 are also completely in their recesses 24,26, so that only their tops and their wedge ridges exposed at the ends of the legs 14,16.

Fig. 3 zeigt eine Ecke des Hohlprofilrahmens 42 von außen in einer Seitenansicht. An dieser Ecke sind zwei Hohlprofil-Endabschnitte, nämlich ein horizontaler Endabschnitt 44 und ein dazu senkrechter Endabschnitt 46, an ihren Gehrungsschnittflächen 48,50 zusammengefügt. Zwischen den Gehrungsschnittflächen 48,50 befindet sich eine Dichtung 52. Fig. 3 shows a corner of the hollow profile frame 42 from the outside in a side view. At this corner, two hollow profile end portions, namely a horizontal end portion 44 and an end portion 46 perpendicular thereto, are joined together at their miter cut surfaces 48, 50. Between the miter cutting surfaces 48,50 is a seal 52nd

In dem Hohlprofilrahmen 42 aus Fig. 3 liegt der Eckverbinder 10 aus den Fig. 1, 2 und 4 ein. Fig. 4 zeigt den Eckverbinder 10 nochmals in einer Ansicht entsprechend der Orientierung des Hohlprofilrahmens 42 in Fig. 3. Der erste Schenkel 14 liegt demnach im in Fig. 3 senkrechten Endabschnitt 46 ein, während der zweite Schenkel 16 in dem verbleibenden horizontalen Endabschnitt 44 einliegt. Durch das Spannen des Spannstücks 22 in Richtung der Ecke 18 mittels der Spannschraube werden somit die Gehrungsflächen 48,50 gegeneinander gedrückt, wie vorstehend beschrieben.In the hollow profile frame 42 made Fig. 3 is the corner connector 10 from the Fig. 1 . 2 and 4 one. Fig. 4 shows the corner connector 10 again in a view corresponding to the orientation of the hollow profile frame 42 in Fig. 3 , The first leg 14 is therefore in in Fig. 3 vertical end portion 46, while the second leg 16 rests in the remaining horizontal end portion 44. By clamping the clamping piece 22 in the direction of the corner 18 by means of the clamping screw thus the miter surfaces 48,50 are pressed against each other, as described above.

Zum Verspannen des Eckverbinders 10 im Hohlprofilrahmen 42 ist es erforderlich, einerseits das Spannstück 22 im Endabschnitt 46 und andererseits den zweiten Schenkel 16 im Endabschnitt 44 fest zu verankern. Dies geschieht mittels Ankerschrauben 54, 56, die von außen durch entsprechende Öffnungen in der Hohlprofil-Außenwand eingesetzt und in das Spannstück 22 bzw. in den Körper des zweiten Schenkels 16 eingedreht sind. In der Ansicht in Fig. 5 sind die Ankerschrauben 56 des zweiten Schenkels 16 sichtbar. Ihre Köpfe liegen in einer Nut auf der Außenseite des Hohlprofilendabschnitts 44 ein. In dieser Ansicht ist auch der Kopf der Spannschraube 58 sichtbar, die sich gemäß der Perspektive in Fig. 5 in die Zeichenebene hinein erstreckt. Die Ankerschrauben 54 zur Verankerung des Spannstücks 22 sind ebenfalls zu erkennen.For bracing the corner connector 10 in the hollow profile frame 42, it is necessary to firmly anchor on the one hand the clamping piece 22 in the end portion 46 and on the other hand, the second leg 16 in the end portion 44. This is done by means of anchor bolts 54, 56, which are inserted from the outside through corresponding openings in the hollow profile outer wall and screwed into the clamping piece 22 and in the body of the second leg 16. In the view in Fig. 5 the anchor bolts 56 of the second leg 16 are visible. Their heads are in a groove on the outside of the hollow profile end portion 44 a. In this view, the head of the clamping screw 58 is visible, which is in accordance with the perspective in Fig. 5 extends into the plane of the drawing. The anchor bolts 54 for anchoring the clamping piece 22 can also be seen.

Fig. 6 zeigt den zweiten Schenkel 16 mit seinen Ankerschrauben 56. Die Struktur des zweiten Schenkels 16 soll einerseits eine gute Stabilität und Verspannbarkeit im Endabschnitt 44 gewährleisten, andererseits materialsparend ausgebildet sein. Die Rippen 18 bilden einen guten Kompromiss zwischen diesen Anforderungen. Fig. 6 shows the second leg 16 with its anchor bolts 56. The structure of the second leg 16 is on the one hand to ensure good stability and bracing in the end portion 44, on the other hand be designed to save material. The ribs 18 make a good compromise between these requirements.

Fig. 7 zeigt den anderen Hohlprofil-Endabschnitt 46. Auf dessen Außenseite verläuft ebenfalls eine Nut, in der die Ankerschrauben 54 für das Spannstück 22 im Innern des Endabschnitts 46 versenkt sind. Fig. 7 shows the other hollow-profile end portion 46. On the outside thereof also extends a groove in which the anchor bolts 54 are sunk for the clamping piece 22 in the interior of the end portion 46.

Gemäß Fig. 8 weist die Außenseite des ersten Schenkels 14, der in dem Hohlprofil-Endabschnitt 46 einliegt, eine ähnliche Außenstruktur auf wie der zweite Schenkel 16. Der Aufbau des Spannstücks 22 mit den darin eingesetzten Ankerschrauben 54 ist ebenfalls gut zu erkennen. Das Spannstück 22 umfasst einen seitlich verbreiterten Kopf 60, der in der Ausnehmung 20 einliegt. Der Kopf weist leicht keilförmig aufeinander zu laufende Außenflächen 62 auf, die beim Hineinziehen des Spannstücks 22 in die Ausnehmung 20 in die seitlichen Grenzflächen der Ausnehmung 22 gepresst werden. Die Spannschraube 58 ist in Fig. 8 ebenfalls teilweise erkennbar.According to Fig. 8 For example, the outer side of the first leg 14, which rests in the hollow-profile end portion 46, a similar outer structure as the second leg 16. The construction of the clamping piece 22 with the anchor bolts 54 inserted therein is also clearly visible. The clamping piece 22 comprises a laterally widened head 60, which rests in the recess 20. The head has slightly wedge-shaped outer surfaces 62 running towards one another, which are pressed into the recess 20 in the lateral boundary surfaces of the recess 22 when the tensioning piece 22 is pulled in. The clamping screw 58 is in Fig. 8 also partially recognizable.

Fig. 9 ist ein Schnitt entlang der Ebene A-A in Fig. 5, der entlang der Achse der Spannschraube 58 verläuft. Er zeigt, wie der erste Schenkel 14 des Eckverbinders 10 im Hohlprofil-Endabschnitt 46 einliegt. Der Schnitt durch das Spannstück 22 zeigt hier ferner, wie der erste Keil 30 seitlich an dem Kopf 60 (siehe Fig. 8) des Spannstücks 22 angeformt ist und wie der Keil 30 und der verbleibende Teil des ersten Schenkels 14 sich zu einem im wesentlichen rechteckigen Querschnitt ergänzen. Durch eine Bewegung des Keils 30 in die in Fig. 9 dargestellte Position wird dieser Querschnitt verbreitert, und der erste Schenkel 14 wird in dem Hohlprofil-Endabschnitt 46 verspannt. Dieses Verspannen geschieht durch eine Drehung der Spannschraube 58, durch welche das Endstück 22 in Fig. 9 nach links in Richtung der Ecke 18 gezogen wird. Fig. 9 is a section along the plane AA in Fig. 5 which extends along the axis of the clamping screw 58. It shows how the first leg 14 of the corner connector 10 rests in the hollow profile end portion 46. The section through the clamping piece 22 also shows here how the first wedge 30 laterally on the head 60 (see Fig. 8 ) of the clamping piece 22 is formed and how the wedge 30 and the remaining part of the first leg 14 complement each other to a substantially rectangular cross-section. By a movement of the wedge 30 in the in Fig. 9 shown position, this cross-section is widened, and the first leg 14 is clamped in the hollow-profile end portion 46. This distortion is done by a rotation of the clamping screw 58 through which the end piece 22 in Fig. 9 is pulled to the left towards the corner 18.

Zur besseren Übersicht sind der erste Schenkel 14 und das Spannstück 22 mit dem daran angeformten ersten Keil 30 in Fig. 10 freigestellt. Diese Schnittansicht in Fig. 10 liegt in einer Ebene B-B in Fig. 6.For a better overview of the first leg 14 and the clamping piece 22 with the molded thereon first wedge 30 in Fig. 10 optional. This sectional view in Fig. 10 is in a level BB in Fig. 6 ,

Die Darstellung in Fig. 11 zeigt einen Schnitt durch den Hohlprofil-Endabschnitt 44 mit dem darin eingesetzten und verspannten zweiten Schenkel 16 des Eckverbinders 10. Erkennbar ist ferner ein Längsschnitt durch den zweiten Keil 32 mit dem daran angeformten Zapfen 40, der in dem Führungsloch 64 am Ende des zweiten Schenkels 16 einliegt. Die Ankerschrauben 56 zur Verankerung des zweiten Schenkels 16 im Hohlprofil-Endabschnitt 44 sind ebenfalls erkennbar, so wie auch ein Querschnitt durch die Spannschraube 58.The representation in Fig. 11 shows a section through the hollow profile end portion 44 with the inserted therein and strained second leg 16 of the corner connector 10. Also visible is a longitudinal section through the second wedge 32 with the formed thereon pin 40, in the guide hole 64 at the end of the second leg sixteenth rests. The anchor bolts 56 for anchoring the second leg 16 in the hollow profile end portion 44 are also recognizable, as well as a cross section through the clamping screw 58th

In Fig. 12 ist der zweite Schenkel 16 mit dem zweiten Keil 32 freigestellt und ohne den Hohlprofil-Endabschnitt 44 dargestellt. Hier ist der Keil 32 zusammen mit Zapfen 40 leicht zum freien Ende des zweiten Schenkels 16 verschoben, d. h. der Zapfen 40 ist geringfügig aus dem Führungsloch 64 herausgezogen. Durch eine Bewegung in das Führungsloch 64 hinein spreizt der zweite Keil 32 den Querschnitt des zweiten Schenkels 16 leicht auf und verspannt ihn innerhalb des Hohlprofil-Endabschnitts 44. Dies geschieht durch eine leichte Verschiebung des Endabschnitts 44 zusammen mit dem darin verankerten zweiten Schenkel 16 als Ausweichbewegung, wenn beim Anziehen der Spannschraube 58 die Gehrungsflächen 48,50 gegeneinander gepresst werden. Das heißt, beim Einziehen des ersten Schenkels 14 des Eckverbinders 10 in Richtung des Spannstücks 22 tritt beim Aufeinandertreffen der Gehrungsflächen 48,50 eine Kraftkomponente auf, die die seitliche Verschiebung des Hohlprofil-Endabschnitts 44 und somit das Verspannen des zweiten Schenkels 16 darin bewirkt.In Fig. 12 is the second leg 16 with the second wedge 32 released and shown without the hollow profile end portion 44. Here, the wedge 32 is slightly displaced together with pin 40 to the free end of the second leg 16, ie, the pin 40 is slightly pulled out of the guide hole 64. By moving into the guide hole 64, the second wedge 32 slightly spreads the cross section of the second leg 16 and tightens it within the hollow profile end portion 44. This is accomplished by a slight displacement of the end portion 44 together with the second leg 16 anchored therein as an evasive movement if, when tightening the clamping screw 58, the miter surfaces 48, 50 are pressed against one another. That is, when retracting the first leg 14 of the corner connector 10 in the direction of the clamping piece 22 occurs at the meeting of the miter surfaces 48,50 a force component that the lateral displacement the hollow profile end portion 44 and thus the bracing of the second leg 16 causes it.
