Abstract

One edge of the frame, parallel to its longitudinal direction, has a cover (8) resting against the pane. The frame is joined by a fixture (1) to a transverse arm. The fixture pin (2) fits into a hole in the cover. A tie piece fitting into a cavity in the frame prevents the fixture slipping towards the pin axis. The part of the outside of the fixture facing away from the transverse arm is rotationally symmetrical with the pin axis (4). The end of the pin is fixed into a bolt (3) rotatably positioned on the pin axis in the fixture.

Description

Die Erfindung bezieht sich auf einen schnell montierbaren Rahmen für Fenster oder Tür, mit einem Höhenschenkel, der auf einem Rand parallel zu seiner Längsrichtung einen Überschlag aufweist, der seinerseits an der Scheibe anliegt, und einem Querschenkel, der mit dem Höhenschenkel durch ein Befestigungselement verbunden ist, das mit einem Stift, der in Richtung seiner Achse senkrecht zur Scheibenebene in ein Loch im Überschlag eingreift, und einem in eine Aussparung des Höhenschenkels einfassenden Verankerungselement, das Verschiebungen des Befestigungselementes in Richtung der Stiftachse verhindert, versehen ist, wobei der Querschenkel stirnseitig auf das Befestigungselement aufgeschoben ist, Gegenstand nach DE 44 02 286.7.The invention relates to a quickly mountable frame for windows or doors, with a height leg, which has a rollover on one edge parallel to its longitudinal direction, which in turn rests on the pane, and a cross leg, which is connected to the height leg by a fastening element , which is provided with a pin, which engages in the direction of its axis perpendicular to the plane of the disc in a flap, and an anchoring element which surrounds a recess in the height leg and prevents displacements of the fastening element in the direction of the pin axis, the cross leg on the front side Fastener is pushed on, object according to DE 44 02 286.7.

Fenster sowie viele Türen bestehen in ihrem grundsätzlichen Aufbau aus einer Scheibe bzw. Füllung, die in einen Rahmen eingebracht ist. Die Druckschrift DE 44 02 286 beschreibt einen Rahmen für Fenster oder Tür, der aus im allgemeinen vertikal verlaufenden Höhenschenkeln und in der Regel horizontalen Querschenkeln aufgebaut ist, die untereinander durch Befestigungselemente verbunden sind. Die Befestigungselemente, die eine schnelle und leichte Montierbarkeit sowie gute Stabilität des Rahmens gewährleisten, sind einerseits stirnseitig in den Querschenkel eingeschoben und dort festgelegt, andererseits mit dem Höhenschenkel verbunden. Dabei greift ein Stift des Befestigungselementes senkrecht zur Ebene der Scheibe in eine Öffnung des Überschlages ein, im allgemeinen eine an den Höhenschenkel angeformte oder aufgesetzte Leiste von etwa rechteckigem Querschnitt, der die Aufnahme der Scheibe seitlich begrenzt. Durch Eingriff eines weiteren Verankerungselementes in eine Aussparung des Höhenschenkels wird die Verschiebung des Befestigungselementes in Richtung der Stiftachse verhindert, so daß eine sichere Verbindung gewährleistet ist. Geeignet ist zu diesem Zweck beispielsweise eine parallel zum Überschlag in den Höhenschenkel eingebrachte Nut, in die ein Steg senkrecht zur Achse des Stiftes eingreift.The basic structure of windows and many doors consists of a pane or panel that is inserted into a frame. The document DE 44 02 286 describes a frame for windows or doors, which is made up of generally vertically extending height legs and generally horizontal cross legs, which are connected to one another by fastening elements. The fasteners, which are quick and easy to assemble and have good stability Ensure the frame, are inserted on the front side in the cross leg and fixed there, on the other hand connected to the height leg. A pin of the fastening element engages perpendicularly to the plane of the pane in an opening of the flap, generally a strip of approximately rectangular cross-section molded or attached to the height leg, which laterally limits the reception of the pane. By engaging a further anchoring element in a recess in the height leg, the displacement of the fastening element in the direction of the pin axis is prevented, so that a secure connection is ensured. Suitable for this purpose is, for example, a groove made parallel to the flap in the height leg, in which a web engages perpendicular to the axis of the pin.

Das Befestigungselement ermöglicht die rechtwinklige Verbindung der Bestandteile eines Rahmens. Zu dekorativen Zwecken oder aus Gründen räumlicher Beschränkungen, beispielsweise bei Altbauten oder im Bereich des Dachausbaus, ist es jedoch vielfach notwendig, Rahmen zu verwenden, deren Bestandteile im beliebigen Winkel zueinander verbunden sind. Für diese Anwendung ist das erläuterte Befestigungselement ungeeignet.The fastening element enables the components of a frame to be connected at right angles. For decorative purposes or for reasons of space restrictions, for example in old buildings or in the area of the loft, it is often necessary to use frames whose components are connected at any angle to each other. The fastener explained is unsuitable for this application.

Weiterhin bestehen Nachteile im Hinblick auf die Herstellung des Rahmens und seiner Elemente. Für einen sicheren Halt des Querschenkels auf dem eingeschobenen Befestigungselement ist eine präzise Passung erforderlich, die eine sorgfältige und teure Fertigung voraussetzt und zur Folge hat, daß Rahmengestalt und Querschnitt des Befestigungselementes geeignet aufeinander abzustimmen sind. Damit wird ein Einsatz universeller, preiswert in großen Stückzahlen gefertigter Befestigungselemente ausgeschlossen.There are also disadvantages with regard to the manufacture of the frame and its elements. For a secure hold of the cross leg on the inserted fastener, a precise fit is required, a careful and requires expensive production and has the consequence that the frame shape and cross section of the fastener are suitably matched. This precludes the use of universal, inexpensive, large numbers of fasteners.

Meist erfolgt eine Verbindung der Rahmenteile über das Befestigungselement hinaus durch Verkleben oder, speziell bei Kunststoffenstern, verschweißen. Dazu werden die Rahmenteile mit dem Befestigungselement zunächst zusammengesetzt und während des Verschweißvorganges vorübergehend wieder auseinander gezogen, um die miteinander zu verbindenden Oberflächen durch das Schweißgerät erwärmen zu können. Bei gebräuchlichen Schweißautomaten besteht das Problem, daß der Vorgang des Auseinanderziehens nur schwer zu kontrollieren ist und die Bauteile vielfach verkanten oder vollständig getrennt werden, so daß es notwendig wird, sie manuell wieder zusammenzufügen. Damit erhöht sich der Arbeitsaufwand erheblich.Usually the frame parts are connected beyond the fastening element by gluing or, especially with plastic windows, welding. For this purpose, the frame parts are first assembled with the fastening element and temporarily pulled apart again during the welding process in order to be able to heat the surfaces to be joined together by the welding device. With conventional automatic welding machines there is the problem that the process of pulling apart is difficult to control and the components are often tilted or completely separated, so that it becomes necessary to put them back together manually. This increases the workload considerably.

Vor diesem Hintergrund hat sich die Erfindung zur Aufgabe gestellt, einen Rahmen zu entwickeln, dessen Schenkel in beliebigem Winkel zueinander verbindbar sind, wobei eine stabile Verbindung auch ohne Übereinstimmung der Querschnitte von Querschenkel und Befestigungselement gewährleistet ist und sich die Verschweißung der Bauteile erheblich erleichtert.Against this background, the object of the invention is to develop a frame, the legs of which can be connected at any angle to one another, a stable connection being ensured even without the cross-sections of the transverse leg and fastening element matching, and the welding of the components being made considerably easier.

Die Aufgabe der Herstellung einer Verbindung im beliebigen Winkel wird erfindungsgemäß dadurch gelöst, daß das Befestigungselement um die Achse des Stiftes drehbar ist. Zu diesem Zweck ist es notwendig, die einander zugeordneten Flächen des Befestigungselementes und des Höhenschenkels rotationssymmetrisch zur Achse des Stiftes auszuführen bzw. die Kontaktflächen mit derartig gestalten Flächen auf achsparallele Linien einzugrenzen. Funktionell gesehen kommt es darauf an, daß Befestigungselement und Höhenschenkel so geformt sind, daß eine Schwenkbewegung um die Achse des Stiftes möglich wird. Da im allgemeinen nur die Einstellung eines begrenzten Winkelbereiches erforderlich ist, kann sich die rotationssymmetrische Ausführung von Flächen entsprechend beschränken, wobei endseitige Anschläge möglich sind. Die Festlegung des Winkels wird entweder durch nachfolgendes starres Verbinden, beispielsweise durch Verschweißung, oder das Zusammenfügen mit weiteren, sich gegenseitig stabilisierend abstützenden Bauteilen zu einem geschlossenen Rahmen erreicht.The task of making a connection in any Angle is solved according to the invention in that the fastening element is rotatable about the axis of the pin. For this purpose, it is necessary to make the mutually assigned surfaces of the fastening element and of the height leg rotationally symmetrical to the axis of the pin or to limit the contact surfaces with surfaces designed in this way to lines parallel to the axis. From a functional point of view, it is important that the fastening element and height leg are shaped in such a way that a pivoting movement around the axis of the pin is possible. Since in general only the setting of a limited angular range is required, the rotationally symmetrical design of surfaces can be limited accordingly, end stops being possible. The angle is determined either by subsequent rigid connection, for example by welding, or the joining together with other mutually stabilizing components to form a closed frame.

Infolge der vorteilhaften, in beliebigem Winkel festlegbaren Verbindungen der Rahmenteile entsteht eine erheblich vergrößerte Gestaltungsvielfalt. Anwendungsbereiche bestehen insbesondere bei Fenstern für spezielle Anwendungszwecke, etwa um einen unter dem Dach befindlichen Raum giebelseitig durch eine Fensterfront abzuschließen. In diesem Fall wird es ermöglicht, Rahmenteile, die parallel der Dachschräge verlaufen, mit horizontalen und vertikalen Rahmenteilen durch das erfindungsgemäße Befestigungselement zu verbinden.As a result of the advantageous connections of the frame parts which can be fixed at any angle, there is a considerably increased variety of designs. Areas of application exist in particular for windows for special applications, for example to close off a room under the roof on the gable end with a window front. In this case it is possible to connect frame parts which run parallel to the roof slope with horizontal and vertical frame parts by means of the fastening element according to the invention.

Die Schenkel des Rahmens werden im allgemeinen als Profile gefertigt, so daß die Einbringung rotationssymmetrischer Strukturen einen erheblichen Mehraufwand bedeutet, speziell dann, wenn eine Vielzahl möglicher Befestigungspunkte vorgesehen ist. Aus diesem Grund wird in einer Weiterbildung der Erfindung vorgeschlagen, den vom Querschenkel abgewandten Bereich der Außenseite des Befestigungselementes, die mit dem Höhenschenkel zusammenwirkt, rotationssymmetrisch zur Achse des Stiftes auszuführen. Notwendig ist dabei lediglich die Rotationssymmetrie ständiger oder möglicher Anlageflächen im vorgesehenen Drehwinkelbereich des Befestigungselementes, während Bereiche, die nicht in Kontakt mit dem Höhenschenkel kommen, von beliebiger Gestalt sein können.The legs of the frame are generally manufactured as profiles, so that the introduction of rotationally symmetrical structures means a considerable additional effort, especially when a large number of possible fastening points is provided. For this reason, it is proposed in a development of the invention to make the region of the outside of the fastening element which faces away from the cross leg and which interacts with the height leg, rotationally symmetrically with respect to the axis of the pin. All that is necessary is the rotational symmetry of permanent or possible contact surfaces in the intended angle of rotation area of the fastening element, while areas that do not come into contact with the height leg can be of any shape.

Eine leicht bewegliche Verbindung, die sich auf vorteilhafte Weise fertigen läßt, ist erreichbar, wenn der Stift endseitig in einem zylindrischen Bolzen befestigt ist, der um die Stiftachse drehbar in das Befestigungselement eingeschoben ist. Alternativ ist denkbar, den Stift an den Bolzen anzuformen. In beiden Fällen ist die Verbindung unterschiedlicher Materialen möglich, etwa der Einsatz eines Kunststoffbolzens in ein metallenes Verbindungselement.An easily movable connection, which can be manufactured in an advantageous manner, can be achieved if the end of the pin is fastened in a cylindrical bolt which is rotatably inserted into the fastening element about the pin axis. Alternatively, it is conceivable to form the pin on the bolt. In both cases, the connection of different materials is possible, for example the use of a plastic bolt in a metal connecting element.

Bei einem drehbaren Befestigungselement ist das Verankerungselement, das eine Verschiebung in Richtung der Stiftachse verhindert, zweckmäßig eine Schraube, die den Bolzen durchgreift und ihn im Höhenschenkel festlegt. Das Befestigungselement ist mit einer Bohrung versehen, durch die die Schraube eindrehbar ist, oder zu diesem Zweck hinreichend weit zur Seite schwenkbar, bevor die Einstellung des vorgesehenen Winkels erfolgt, bei dem die Schraube möglicherweise unzugänglich ist. Daher weist es bevorzugt eine derartige Ausnehmung im Bereich der Schraube auf, daß seine Drehbarkeit erhalten bleibt.In the case of a rotatable fastening element, the anchoring element, which prevents displacement in the direction of the pin axis, is expediently a screw which engages through the bolt and it in the height limb specifies. The fastening element is provided with a bore through which the screw can be screwed in or, for this purpose, can be pivoted sufficiently far to the side before setting the intended angle at which the screw may be inaccessible. Therefore, it preferably has such a recess in the area of the screw that its rotatability is retained.

Weiterhin wird vorgeschlagen, daß der Querschenkel mit Öffnungen oder Erhöhungen auf seiner Innenseite ausgestattet ist, die eine etwa parallel zu seiner Stirnfläche verlaufende Kante besitzen. Ein vorteilhaftes, mit dem Querschenkel zusammenwirkendes Befestigungselement ist mit federnd angebrachten Haken versehen, die eine Kraft gegen die Innenseite des Querschenkels ausüben und die Kanten hintergreifen. Damit wird der aufgeschobene Querschenkel unmittelbar am Befestigungselement fixiert, so daß weitere Verbindungen nicht bzw. nur zur Verstärkung notwendig sind.Furthermore, it is proposed that the cross leg be provided with openings or elevations on its inside, which have an edge running approximately parallel to its end face. An advantageous fastening element which interacts with the cross leg is provided with spring-mounted hooks which exert a force against the inside of the cross leg and engage behind the edges. So that the slid cross leg is fixed directly to the fastener, so that further connections are not necessary or only for reinforcement.

Bevorzugt ist das Befestigungselement mit mehreren, symmetrisch zur Längsachse des Querschenkels angeordneten Haken versehen, so daß der Eingriff in einer präzise vorgegebenen, verkantungsfreien Position erfolgt.The fastening element is preferably provided with a plurality of hooks arranged symmetrically to the longitudinal axis of the cross leg, so that the engagement takes place in a precisely predetermined, tilt-free position.

In einer Abwandlung sind die Haken in Längsrichtung des Querschenkels von den Kanten beabstandet angeordnet. Auf diese Weise wird erreicht, daß sich der Querschenkel nach dem Aufschieben auf das Befestigungselement eine begrenzte Strecke vom Höhenschenkel abziehen läßt, ohne daß eine vollständige Trennung erfolgt. In der Folge erleichtert sich insbesondere eine Verschweißung von Quer- und Höhenschenkeln aus Kunststoff erheblich, die zur Erhitzung der zu verschweißenden Flächen vorübergehend auseinanderzuziehen sind. Die Haken verhindern ein Verkanten oder vollständiges Abziehen des Querschenkels vom Befestigungselement, so daß ein manuelles Ausrichten der Bauteile bzw. Aufschieben entfallen kann und ein vollautomatischer Ablauf des Schweißvorgangs gewährleistbar ist.In a modification, the hooks are arranged at a distance from the edges in the longitudinal direction of the cross leg. In this way it is achieved that the cross leg after sliding onto the fastener allows a limited distance to be deducted from the upper leg without complete separation. As a result, welding of transverse and vertical limbs made of plastic, in particular, is made considerably easier and must be temporarily pulled apart to heat the surfaces to be welded. The hooks prevent the cross leg from tilting or being completely pulled off from the fastening element, so that manual alignment of the components or sliding on can be dispensed with and a fully automatic sequence of the welding process can be ensured.

Mit dem Ziel, daß sich eine präzise Passung zwischen Befestigungselement und umgreifendem Querschenkel zur Erreichung eines sicheren Haltes erübrigt, weisen beide Bauelemente eine durchgehende parallel der Stirnfläche des Querschenkels verlaufende Bohrung auf, die im Querschenkel und im äußeren Bereich des Befestigungselementes erweitert ist. In die erweiterten Bereiche sind Hülsen formschlüssig eingeschoben, die mit einem Rand auf der Außenseite des Querschenkels anliegen. Damit wird eine Bewegung des Querschenkels relativ zum Befestigungselement in Richtungen senkrecht der Bohrung verhindert. Zwischen den erweiterten Bereichen verbleibt ein Steg, an den die Hülsen beidseitig von einer sie durchgreifenden Schraube angepreßt werden. Somit wird auch eine Verschiebung des Befestigungselementes in Richtung der Bohrung ausgeschlossen, da eine Abstützung über die Hülsen mit den auf dem Querschenkel anliegenden Rändern erfolgt. Der erhebliche Vorteil besteht darin, daß eine sichere, in allen Raumrichtungen starre Verbindung zwischen Querschenkel und Befestigungselement selbst dann sichergestellt ist, wenn beide Bauteile allseitig voneinander beabstandet sind. In der Folge lassen sich einheitliche Befestigungselemente für unterschiedliche Typen von Profilen verwenden. Weiterhin wird die Möglichkeit eröffnet, nebeneinander angeordnete, parallel zueinander verlaufende Schenkel im Bereich des Befestigungselementes miteinander zu verbinden, indem eine Hülse in die Bohrungen beider Schenkel eingreift, die von einer durchgehenden Schraube durchgriffen werden.With the aim that a precise fit between the fastening element and the encompassing cross leg is unnecessary to achieve a secure hold, both components have a continuous bore parallel to the end face of the cross leg, which is expanded in the cross leg and in the outer region of the fastening element. Sleeves are positively inserted into the enlarged areas and rest with an edge on the outside of the cross leg. This prevents movement of the cross leg relative to the fastening element in directions perpendicular to the bore. Between the extended areas there remains a web against which the sleeves are pressed on both sides by a screw which penetrates them. A displacement of the fastening element in the direction of the bore is thus also excluded, since support is provided via the sleeves with the edges resting on the cross leg. The significant advantage is that a safe, rigid connection in all spatial directions between the cross leg and the fastening element is ensured even when the two components are spaced apart on all sides. As a result, uniform fastening elements can be used for different types of profiles. Furthermore, the possibility is opened to connect adjacent, mutually parallel legs in the area of the fastening element by a sleeve engaging in the bores of both legs, which are penetrated by a continuous screw.

Figur 1 zeigt ein Befestigungselement (1), das zur Verbindung der Schenkel von Fenster oder Türrahmen geeignet ist. Während ein Querschenkel (6) in senkrechter Richtung auf das Befestigungselement (1) aufgeschoben wird, erfolgt die Verbindung mit einem Höhenschenkel (nicht dargestellt) durch einen Stift (2), der in axialer Richtung über das Zentrum eines drehbar im Befestigungselement (1) angeordneten Bolzens (3) hervor steht. Damit die Drehbarkeit des gesamten Befestigungselementes (1) um die Achse (4) des Stiftes (2) in einem Winkelbereich auch dann gewährleistet ist, wenn es in einen Höhenschenkel eingebracht ist, wird seine Unterseite (5), d.h. die vom Querschenkel (6) abgewandte Seite, rotationssymmetrisch zur Achse (4) des Stiftes (2) ausgeführt.Figure 1 shows a fastener (1) which is suitable for connecting the legs of the window or door frame. While a cross leg (6) is pushed onto the fastening element (1) in the vertical direction, the connection to a height leg (not shown) is made by a pin (2) which is arranged in the axial direction over the center of a rotatable element in the fastening element (1) Bolt (3) protrudes. So that the rotatability of the entire fastening element (1) about the axis (4) of the pin (2) in an angular range is ensured even when it is inserted into a height leg, its underside (5), i.e. the side facing away from the cross leg (6), rotationally symmetrical to the axis (4) of the pin (2).

Die Darstellung in Figur 2 zeigt in zu Figur 1 senkrechter Ansicht die Einbringung eines Befestigungselementes (1) in den Höhenschenkel (7), wobei der Stift (2) in eine Öffnung eingreift, die in den Überschlag (8) eingebracht ist. Um zu verhindern, daß der Stift (2) bei axialer Belastung aus dem Überschlag (8) heraus gleitet, ist der Bolzen (3) endseitig mit einer Bohrung (9) versehen, durch die eine Schraube in den Höhenschenkel (7) eindrehbar ist. Eine Ausnehmung (10) des Befestigungselementes (1) gewährleistet in diesem Fall, daß dessen Drehbarkeit um die Achse (4) des Stiftes (2) erhalten bleibt, auch wenn der Kopf einer Schraube geringfügig über die Bohrung (9) übersteht. Die Drehbarkeit nach dem Einbringen der Schraube ist erforderlich, da letztere nur bei geeigneter Ausrichtung des Befestigungselementes (1) durch die Öffnung (11) zugänglich ist.The illustration in FIG. 2 shows, in a view perpendicular to FIG. 1, the introduction of a fastening element (1) into the height leg (7), the pin (2) engaging in an opening which is introduced into the flap (8). In order to prevent the pin (2) from sliding out of the flap (8) under axial load, the bolt (3) is provided at the end with a bore (9) through which a screw can be screwed into the height leg (7). In this case, a recess (10) in the fastening element (1) ensures that its rotatability about the axis (4) of the pin (2) is retained, even if the head of a screw protrudes slightly beyond the bore (9). The rotatability after the screw has been inserted, it is necessary that the latter can only be accessed through the opening (11) if the fastening element (1) is suitably aligned.

In Figur 3 wird ein - im Beispiel nicht um den Stift (2) drehbares - Befestigungselement (1) wiedergegeben, das auf seiner Außenseite mit Haken (12) versehen ist, die zum Hintergreifen von Kanten (13) des Querschenkels (6) vorgesehen sind, die durch die Ränder von in den Querschenkel (6) eingebrachten Öffnungen gebildet werden. Die federnd in das Befestigungselement einschiebbaren Haken (12) verhindern, daß der Querschenkel (6) weiter als bis zur Kante (13) vom Befestigungselement (1) abgezogen wird, und gewährleisten durch die symmetrische Anordnung zusammen mit den Kanten (13), daß bei diesem Vorgang keine Verkantung erfolgt.FIG. 3 shows a fastening element (1) which in the example cannot be rotated about the pin (2) and which is provided on its outside with hooks (12) which are provided for engaging behind edges (13) of the transverse leg (6) formed by the edges of openings made in the cross leg (6). The resiliently insertable hooks (12) prevent the cross leg (6) from being pulled off as far as the edge (13) from the fastening element (1) and ensure through the symmetrical arrangement together with the edges (13) that at no tilting occurs during this process.

Figur 4 läßt ein in einen Querschenkel (6) eingeschobenes Befestigungselement (1) erkennen, wobei auf die Darstellung des parallel zur Bildebene verlaufenden Höhenschenkels (7) verzichtet wurde. Zur Gewährleistung einer sicheren Verbindung weisen sowohl der Querschenkel (6) als auch das Befestigungselement (1) eine durchgehende Bohrung auf, in die eine Schraube (14) eingebracht ist. Im äußeren Bereich des Befestigungselementes (1) und im Querschenkel (6) weist die Bohrung Erweiterungen auf, die von Hülsen (15) ausgefüllt sind, die ihrerseits mit einem Rand (16) auf der Außenseite des Querschenkels (6) anliegen. Zwischen den erweiterten Bereichen der Bohrung verbleibt ein Steg (17), an den die Hülsen (15) durch die Schraube (14) beidseitig angepreßt werden. Obwohl das Befestigungselement beidseitig durch einen Spalt (18) vom Querschenkel (6) beabstandet ist, gewährleistet seine Abstützung über den Steg (17) und die Hülsen (15) mit den Rändern (16), daß eine Verschiebung in Richtung der Schraubenachse ausgeschlossen ist. Verschiebungen senkrecht dazu werden durch die allseitig anliegenden Hülsen (15) verhindert. Der Vorteil dieser Ausgestaltung der Erfindung besteht insbesondere darin, daß sich eine präzise Passung des BefestigungselementeS (1) im Querschenkel (6) erübrigt und einheitliche Befestigungselemente auch bei unterschiedlichen Schenkelprofilen einsetzbar sind.FIG. 4 shows a fastening element (1) pushed into a cross leg (6), the height leg (7) running parallel to the image plane being omitted. To ensure a secure connection, both the cross leg (6) and the fastening element (1) have a through hole into which a screw (14) is inserted. In the outer area of the fastening element (1) and in the cross leg (6), the bore has extensions which are filled by sleeves (15), which in turn have an edge (16) on the outside of the cross leg (6). Between the enlarged areas of the bore there remains a web (17) against which the sleeves (15) are pressed on both sides by the screw (14). Although the fastening element is spaced on both sides by a gap (18) from the cross leg (6), its support via the web (17) and the sleeves (15) with the edges (16) ensures that a displacement in the direction of the screw axis is excluded. Displacements perpendicular to it are prevented by the sleeves (15) resting on all sides. The advantage of this embodiment of the invention is, in particular, that there is no need for a precise fit of the fastening element S (1) in the transverse leg (6) and uniform fastening elements can also be used with different leg profiles.

Im Ergebnis wird auf diese Weise die Variationsbreite möglicher Verbindungen erheblich vergrößert, während sich die Fertigung des Rahmens und seiner Bauteile vereinfacht und auch das Zusammenwirken von Bauteilen ermöglicht wird, die keine präzise Passung aufweisen.As a result, the range of possible connections is increased considerably, while the manufacture of the frame and its components is simplified and the interaction of components that do not have a precise fit is made possible.
