Description

Die Erfindung betrifft einen Eckverbinder für Zargen, Tür- oder Fensterstöcke, die aus mehreren Profilteilen aufgebaut sind und die im Bereich der Stoßfuge an ihrer dem Mauerwerk zugewandten Seitenwand über die Stoßfuge stellenweise hinausragende Führungsflächen aufweisen, die mit entsprechenden Führungsflächen des anderen Profilteiles korrespondieren, wodurch die Lage der beiden Profilteile zueinander bestimmt wird, wobei an jedem Profilteil zumindest ein Vorsprung vorgesehen ist und wobei korrespondierende Vorsprünge durch Verdrehen einer Klemmscheibe zueinanderbewegt und in der durch die Führungen bzw. Profilteile bestimmten Endlage gehalten werden.The invention relates to a corner connector for frames, door or window frames, which are constructed from several profile parts and which in the area of the butt joint on their side wall facing the masonry have protruding guide surfaces in places, which correspond to corresponding guide surfaces of the other profile part, whereby the The position of the two profile parts relative to one another is determined, with at least one projection being provided on each profile part and corresponding projections being moved toward one another by rotating a clamping disk and being held in the end position determined by the guides or profile parts.

Ein derartiger Eckverbinder ist aus der weiter unten besprochenen DE-A-1 784 549 bekannt.Such a corner connector is known from DE-A-1 784 549 discussed below.

Ein zunehmendes Problem im Baugewerbe stellen die Transportkosten von zargen und Stöcken dar, da dabei hauptsächlich leerer Raum transportiert wird. Dazu kommt noch, daß diese Teile derzeit fabriksmäßig vorgefertigt werden und auf der Baustelle nach dem Einsetzen nicht mehr oder nur mit einem Finalanstrich od.dgl. behandelt werden. Es muß daher jede Zarge so verpackt sein, daß sie den rauhen Bedingungen beim Transport und auf der Baustelle unbeschadet übersteht. Auch diese Anforderungen lassen sich mit zerlegten Zargen leichter erfüllen, da dabei handlicheres Verpackungsmaterial verwendet werden kann und da die Hanhabung von länglichen Teilen wesentlich weniger Beschädigungen mit sich bringt, als die Handhabung flächiger Teile, die größer sind als übliche Türen.An increasing problem in the construction industry is the transportation costs of frames and sticks, since mainly empty space is transported. In addition, these parts are currently prefabricated in the factory and no longer or only with a final coat or the like on the construction site after insertion. be treated. Each frame must therefore be packed in such a way that it can withstand the harsh conditions during transport and on the construction site without damage. These requirements can also be more easily met with disassembled frames, since more manageable packaging material can be used and since the handling of elongated parts causes far less damage than the handling of flat parts that are larger than conventional doors.

Es ist derzeit zur Verbindung der Zargenlängsteile mit dem Sturzteil aus der Praxis bekannt gewesen, bei metallischen Zargen, bei denen diese Teile mit 45°-igen Gehrungsschnitt aneinanderstoßen, jeweils einen Eckverbinder zu befestigen, der entlang des Gärungsschnittes ein zick-zackförmiges Profil aufweist, dessen Spitzen über die Schnittkanten vorstehen und dessen Täler hinter der Kante zurückbleiben, wobei am anderen Teil der Zarge ein entsprechendes Zick-Zackprofil vorgesehen ist. Die Bauteile, die das Profil tragen, werden üblicherweise mittels Punktschweißung am entsprechenden zargenteil befestigt.It has currently been known from practice for connecting the longitudinal frame parts to the lintel part, in the case of metallic frames in which these parts abut with a 45 ° miter cut, a corner connector in each case to be attached, which has a zigzag-shaped profile along the fermentation cut, the tips of which protrude beyond the cut edges and the valleys remain behind the edge, a corresponding zigzag profile being provided on the other part of the frame. The components that support the profile are usually attached to the corresponding frame part by means of spot welding.

Auf der Baustelle werden die beiden Zargenteile rechtwinkelig zur Gehrungsschnittlinie aneinander geschoben, wobei durch die vorspringenden Profilteile eine Justierung des Zargenbleches in seiner Ebene erfolgt. Nach erfolgtem Zusammenschieben wird über zumindest zwei aus dem Eckverbinder aufgebogenen Laschen eine Art Keil geschoben, der mittels Reibung die Verbindung fixieren soll. Der Keil besteht wiederum aus einem Blechplättchen (Keilplatte) mit schlitzartigen Ausnehmungen, in die die aufgebogenen Laschen eingeführt werden, worauf mittels eines Hammer oder einer Zange das Auftreiben der Lasche erfolgt.On the construction site, the two frame parts are pushed together at right angles to the miter cut line, with the projecting profile parts adjusting the frame plate in its plane. After pushing together, a kind of wedge is pushed over at least two tabs bent out of the corner connector, which is intended to fix the connection by means of friction. The wedge again consists of a sheet metal plate (wedge plate) with slot-like recesses into which the bent tabs are inserted, whereupon the tab is opened using a hammer or pliers.

Diese Anordnung weist eine Reihe schwerwiegender Nachteile auf:This arrangement has a number of serious disadvantages:

Durch die Notwendigkeit, die Zargenteile rechtwinkelig zum Gehrungsschnitt aneinander zu schieben, ist es nicht möglich, am Sturzteil der Zarge eine Führung vorzusehen, die die Innenseite des entsprechenden Zargenlangteiles federnd unterstützt und damit das liniengenaue Zusammentreffen im sichtbaren Bereich der Zarge ermöglicht.Due to the necessity of pushing the frame parts together at right angles to the miter cut, it is not possible to provide a guide on the lintel part of the frame, which resiliently supports the inside of the corresponding frame long part and thus enables a line-exact meeting in the visible area of the frame.

Ein weiterer Nachteil besteht darin, daß die Laschen aus kosten- und fertigungstechnischen Gründen durch Ausstanzen und Aufbiegen hergestellt werden müssen, was keine große Genauigkeit zuläßt. Aus diesem Grund kommt es beim Zusammenbau auf der Baustelle immer wieder zu Problemen, wenn nämlich das Aufbringen der Keilplatte durch zu großen Abstand der Laschen unmöglich wird oder wennn beim Aufbringen der Keilplatte durch zu geringen Laschenabstand keine Klemmwirkung erreicht wird.Another disadvantage is that the tabs have to be manufactured by punching and bending for cost and manufacturing reasons, which does not allow great accuracy. For this reason, problems arise again and again when assembling on the construction site, namely that the application of the wedge plate becomes impossible due to the spacing of the tabs being too great or if the wedge plate is applied due to the tab spacing being too small no clamping effect is achieved.

Schließlich ist die Art der Aufbringung der Keilplatte für die Zarge selbst schädlich, da sowohl das Arbeiten mit einem entsprechend schweren Hammer als auch die Verwendung einer Zange, bei der die zweite Backe zwangsweise auf der sichtbaren Zargenaußenseite anliegen muß, leicht zu Beschädigungen der Zarge führt.Finally, the type of application of the wedge plate is harmful to the frame itself, since both working with a correspondingly heavy hammer and using a pair of pliers, in which the second jaw must inevitably rest on the visible outside of the frame, easily damage the frame.

Ein weiteres Problem liegt darin, daß die aufgebogenen Laschen eine Höhe besitzen, die sie über den Bördelrand der Zarge vorstehen läßt, was es unter Umständen notwendig macht, das Mauerwerk an dieser Stelle auszunehmen. Da auch die Keilplatte Fixierungsaufbiegungen aufweist, die sich in die Laschenseitenkanten verklemmen sollen, steht auch diese Platte zumindest teilweise über das Mauerprofil vor. Da die entsprechende Fläche relativ groß ist, besonders wenn mehr als zwei Laschen verwendet werden, kann dadurch eine Vorbearbeitung der Wand vor der Montage der Zarge notwendig werden.Another problem is that the bent tabs have a height that allows them to protrude beyond the flanged edge of the frame, which may make it necessary to remove the masonry at this point. Since the wedge plate also has fixation bends which are intended to jam into the tab side edges, this plate also projects at least partially beyond the wall profile. Since the corresponding area is relatively large, especially if more than two brackets are used, it may be necessary to pre-process the wall before installing the frame.

Aus der DE-A-22 22 590 ist eine Verbesserung dieser Bauart bekannt, sie sieht vor, die Keilplatte in Richtung der Trennfuge aufzutreiben. Die Laschen sind durch pilzartige Vorsprünge ersetzt, an denen ein Maul der Keilplatte in einem Winkel von etwa 30° zur Trennfuge angreift. Die Klemmkraft hat somit eine Resultierende, die versucht, die Klemmplatte in Löse-Richtung zu verschieben. Um dies zu verhindern, wird in eine Ausnehmung am maulabgewandten Ende der Keilplatte die Stoßstelle der von den Profilen gebildeten Ecke eingesetzt. Damit wird aber diese Ecke auseinandergedrückt (wenn die Vorsprünge etwas zu weit voneinander entfernt sind) oder die Klemmkraft nicht erhalten (wenn die Vorsprünge nicht weit genug voneinander entfernt sind). Es sind engste Toleranzen einzuhalten, um dieses System funktionsfähig zu machen. Dabei sind die Probleme der Führung beim Zusammenbau und der Justierung noch nicht berücksichtigt.An improvement of this type is known from DE-A-22 22 590, it provides for the wedge plate to be driven in the direction of the parting line. The tabs are replaced by mushroom-like projections on which a mouth of the wedge plate engages at an angle of about 30 ° to the parting line. The clamping force thus has a resultant who tries to move the clamping plate in the release direction. To prevent this, the joint of the corner formed by the profiles is inserted into a recess at the end of the wedge plate facing away from the mouth. This pushes this corner apart (if the protrusions are a little too far apart) or does not maintain the clamping force (if the protrusions are not far enough apart). Close tolerances must be observed to make this system work. The problems of guidance during assembly and adjustment have not yet been taken into account.

Aus der DE-A-1 784 549, der der einleitende Teil des Anspruches 1 entspricht, ist eine Lösung bekannt, bei der eine spiralige Führungsausnehmung einer Klemmplatte über drei Vorsprünge gelegt und durch Verdrehen festgeklemmt wird. Dabei wird erreicht, daß keine Tendenz zum Lockern der Klemmung auftritt, doch ist durch die ungleiche Anordnung der Vorsprünge (Zwei auf einem Profilteil, einer am anderen) keine definierte Spannrichtung erzielbar. Die Bewegung der Profilteile zueinander erfolgt annähernd normal zur Stoßfuge, wobei durch die Art der Klemmung und eine ungeschickte Anordnung von schrägen Führungsflächen eine schiefe Montage unvermeidbar ist.From DE-A-1 784 549, which is the introductory part of claim 1, a solution is known in which a spiral guide recess of a clamping plate is placed over three projections and clamped by twisting. It is achieved that there is no tendency to loosen the clamping, but due to the uneven arrangement of the projections (two on one profile part, one on the other) no defined clamping direction can be achieved. The movement of the profile parts to each other is almost normal to the butt joint, whereby due to the type of clamping and an awkward arrangement of inclined guide surfaces, an inclined installation is unavoidable.

Die Erfindung hat es sich zum Ziel gesetzt, diese Nachteile zu vermeiden und einen Eckverbinder zu schaffen, bei dem zuverläßig eine dauerhafte Klemmung erreicht wird, ohne daß extreme Toleranzen eingehalten werden müssen. Darüberhinaus sollen nur einfach und billig herzustellende Bauteile verwendet werden.The aim of the invention is to avoid these disadvantages and to create a corner connector in which a permanent clamping is reliably achieved without extreme tolerances having to be observed. In addition, only components that are simple and inexpensive to manufacture should be used.

Dazu wird erfindungsgemäß vorgeschlagen, daß, wie bei Eckverbindern mit verschieblichen Klemmplatten bekannt, jeweils ein Paar Vorsprünge gemeinsam geklemmt werden, dadurch daß die Vorsprünge auf der dem anderen Zargenteil abgewandten Seite hinterschnitten sind und dadurch, daß die Klemmscheibe eine ovale Ausnehmung aufweist, deren kürzester Durchmesser kleiner ist als der kürzeste Abstand der Hinterschneidungen der beiden Vorsprünge im montierten Zustand und deren größter Durchmesser größer ist als der größte Abstand der Vorsprünge im montierten Zustand.For this purpose, it is proposed according to the invention that, as is known in corner connectors with displaceable clamping plates, a pair of projections are clamped together, in that the projections are undercut on the side facing away from the other frame part and in that the clamping disk has an oval recess, the shortest diameter of which is smaller than the shortest distance between the undercuts of the two projections in the assembled state and the largest diameter of which is larger than the largest distance between the projections in the assembled state.

Damit wird wesentlich mehr erreicht, als eine Kombination der Maßnahmen der beiden oben zitierten Druckschriften erwarten läßt: Die Klemmscheibe ist durch die Hinterschneidungen unverlierbar und durch die Reibungsverhältnisse lockerungssicher; sie wird nur auf Zug, kaum auf Biegung und nicht auf Druck beansprucht und braucht daher nicht massiv zu sein; sie liegt an keinem anderen Bauteil an. Die Vorsprünge sind günstig in der Mitte des Profiles anzuordnen; werden mehrere Paare vorgesehen, kann eine vorteilhafte Verteilung der Klemmkräfte über die Länge der Stoßfuge erreicht werden. Es wird eine durch die Mittelpunkte der beiden Vorsprünge gegebene Klemmrichtung erzielt, was für eine fugenlose Verbindung wesentlich ist.This means that much more is achieved than a combination of the measures of the two publications cited above can be expected: the clamping disc is captive due to the undercuts and secure against loosening due to the frictional conditions; it is only subjected to tension, hardly to bending and not to pressure and therefore need not be massive; it is not in contact with any other component. The protrusions are cheap in the middle of the Arrange profiles; if several pairs are provided, an advantageous distribution of the clamping forces over the length of the butt joint can be achieved. A clamping direction given by the centers of the two projections is achieved, which is essential for a seamless connection.

In einer bevorzugten Ausgestaltung ist vorgesehen, daß die Vorsprünge in Schnittebenen parallel zur Ebene der Klemmscheibe zumindest angenähert die Form eines Kreisbogenabschnittes aufweisen. Dies erleichtert das Aufsetzen der Klemmscheibe, vergrößert die Auflagefläche und vermindert damit die Pressung.In a preferred embodiment it is provided that the projections have at least approximately the shape of a circular arc section in sectional planes parallel to the plane of the clamping disk. This makes it easier to put on the clamping disc, increases the contact area and thus reduces the pressure.

In einer vorteilhaften Ausgestaltung besteht jeder Vorsprung aus einem kreisbogenförmigen Abschnitt der Eckplatte, der hochgebogen und dessen nunmehr oberster Teil über 90° verbogen wird, sodaß er die Hinterschneidung ausbildet. Diese Maßnahme ermöglicht eine besonders kostengünstige Herstellung der Verbindung und hat darüberhinaus den Vorteil, daß beim Verdrehen der Klemmplatte diese nach zu den Eckplatten hin verschoben wird, wodurch die beiden Eckplatten zwischen dem Zargenmaterial einerseits und der Klemmplatte andererseits eingeklemmt werden, was eine hervorragende Justierung und mechanische Versteifung der Zargenteile und ihrer Verbindung mit sich bringt.In an advantageous embodiment, each projection consists of an arcuate section of the corner plate, which is bent up and whose uppermost part is now bent over 90 °, so that it forms the undercut. This measure enables a particularly cost-effective production of the connection and also has the advantage that when the clamping plate is rotated, it is moved towards the corner plates, as a result of which the two corner plates are clamped between the frame material on the one hand and the clamping plate on the other, which is an excellent adjustment and mechanical Stiffening of the frame parts and their connection.

Vorteilhafterweise weist die Klemmscheibe einen polygonalen Rand auf, der umgebördelt ist. Dadurch ist die Verwendung eines schlüsselartigen Werkzeuges zum Verdrehen der Klemmscheibe leicht möglich.The clamping disk advantageously has a polygonal edge which is flanged. This makes it easy to use a key-like tool for rotating the clamping disk.

In einer bevorzugten Ausgestaltung ist vorgesehen, daß die Richtung, in der die Führungen die beiden zu verbindenden Profilteile zueinander bei Annäherung führen, mit der Richtung, die durch die Mitten der beiden Vorsprünge gegeben ist, einen Winkel aufweist. Dies macht es erstmals möglich, durch das Klemmen gemeinsam mit der Führung eine definierte Endlage zu erreichen, da Klemmrichtung und Führungsrichtung nicht zusammenfallen.In a preferred embodiment it is provided that the direction in which the guides lead the two profile parts to be joined to one another when approaching is at an angle with the direction given by the centers of the two projections. This makes it possible for the first time to achieve a defined end position by clamping together with the guide, since the clamping direction and direction of leadership do not coincide.

Besonders erleichtert wird das Zusammenfügen der Profilteile dadurch, daß die Führungen der beiden zu verbindenden Profilteile ein Verschiebung in der Längsrichtung eines der beiden Profilteiles erlauben.The joining of the profile parts is particularly facilitated by the fact that the guides of the two profile parts to be connected allow a displacement in the longitudinal direction of one of the two profile parts.

Die Erfindung wird an Hand der beiliegenden Zeichnung näher erläutert, in der Fig. 1 zwei miteinander verwendbare Eckplatten zeigt, Fig. 2 zeigt die Eckplatten in der Zarge befestigt, mit aufgesetzter Klemmplatte und eingelegtem Schlüssel, die Fig. 3 zeigt eine Klemmplatte und Fig. 4 einen Schlüssel für das Fixieren der Klemmplatte.The invention is explained in more detail with reference to the accompanying drawing, in which FIG. 1 shows two corner plates that can be used with one another, FIG. 2 shows the corner plates fastened in the frame, with a clamping plate and key inserted, FIG. 3 shows a clamping plate and FIG. 4 a key for fixing the clamping plate.

Eine Eckplatte 1 weist Vorsprünge 2 und 3 auf, die mit Ausnehmungen 4, 5 der Gegenklemmplatte 6 zusammenwirken. Auch die Klemmplatte 6 weist Vorsprünge 7, 8 auf, die mit Ausnehmungen 9, 10 der ersten Eckplatte zusammenwirken. Die Bezeichnung Vorsprünge bzw. Ausnehmungen bezieht sich jeweils auf die strichpunktiert eingezeichnete Stoßlinie zwischen den beiden Zargenteilen, die im vorliegenden Fall mit einer 45° -Gehrung aneinanderstoßen.A corner plate 1 has projections 2 and 3, which cooperate with recesses 4, 5 of the counter-clamping plate 6. The clamping plate 6 also has projections 7, 8 which cooperate with recesses 9, 10 of the first corner plate. The term protrusions or recesses refers to the dash-dotted line between the two frame parts, which in the present case abut with a 45 ° miter.

Im Bereich dieser Stoßlinie weist die Eckplatte 1 einen Vorsprung 11 auf, der durch Umbiegen eines Teiles der Eckplatte 1 gebildet ist. Das obere Ende des Vorsprunges 11, in der Figur mit 12 bezeichnet, ist über 90° aufgebogen, sodaß es einen größeren Abstand zur Stoßfuge aufweist als der Teil des Vorsprunges 11, der nahe der Platte 1 ist. In der Figur sind die Vorsprünge und Ausnehmungen ebenso wie der pilzartig vorstehende Rand mit scharfen Kanten gezeichnet, doch muß berücksichtigt werden, daß diese Teile aus Blech ausgestanzt und sodann gebogen werden, was dazu führt, daß keine scharfen Kanten, sondern runde Formen entstehen. Der Vorsprung 11 weist somit Pilzform auf.In the area of this abutting line, the corner plate 1 has a projection 11, which is formed by bending part of the corner plate 1. The upper end of the projection 11, designated 12 in the figure, is bent over 90 °, so that it is at a greater distance from the butt joint than the part of the projection 11 which is close to the plate 1. In the figure, the projections and recesses as well as the mushroom-like protruding edge are drawn with sharp edges, but it must be taken into account that these parts are punched out of sheet metal and then bent, which leads to the fact that there are no sharp edges but round shapes. The projection 11 thus has a mushroom shape.

Die Eckplatte 6 weist analog zum Vorsprung 11 einen Vorsprung 13 auf, der ebenfalls mit einem überbogenen Rand 12 (Bördelung) versehen ist.Analogously to the projection 11, the corner plate 6 has a projection 13 which is also provided with an over-bent edge 12 (flanging).

Die Eckplatten 1, 6 werden in der Fabrik mit passenden Vorrichtungen an der der Mauer zugewandten seitlichen Wand der Zargenteile befestigt, bevorzugt durch Punktschweißen. Zu diesem Zweck sind Schweißbuckel 22 vorgesehen.The corner plates 1, 6 are fastened in the factory with suitable devices to the side wall of the frame parts facing the wall, preferably by spot welding. Weld bosses 22 are provided for this purpose.

In der Fig. 1 sind die Eckplatten 1, 6 verdoppelt, d.h. gespiegelt an einer Geraden 23 bzw. 24 dargestellt, was es ermöglicht, sie für linke und rechte Seiten der Zargen gleichermaßen verwenden zu können. Dabei ist bei den Eckplatten 1 der Vorsprung 3 entweder abbrechbar auszugestalten oder nur auf einem Teil der Eckplatten vorzusehen, da dieser Vorsprung sonst über die Zarge hinausragt, was eine Montageverhindert. Der fehlende Teil ist strichliert mit 3' eingezeichnet.In Fig. 1 the corner plates 1, 6 are doubled, i.e. shown mirrored on a straight line 23 or 24, which makes it possible to use them equally for left and right sides of the frames. In the case of the corner plates 1, the projection 3 is either to be designed to be breakable or to be provided only on a part of the corner plates, since this projection otherwise projects beyond the frame, which prevents assembly. The missing part is shown in dashed lines at 3 '.

Die Fig. 2 zeigt den Montagezustand, wobei zu erkennen ist, daß der Zargenteil, der die Eckplatte 6 trägt, in der Fig. 2 von rechts nach links an den Zargenteil mit der Eckplatte 1 herangeschoben worden ist. Eine polygonale Klemmscheibe 14, die eine ovale Ausnehmung 15 aufweist und deren Rand 16 aufgebördelt ist (Fig. 3), ist über die beiden Vorsprünge 11, 13 gesteckt worden, wobei der größte Durchmesser der Ausnehmung 15 größer ist als der größte Abstand zwischen den Vorsprüngen 11, 13 im Bereich ihrer Bördelungen 12.Fig. 2 shows the state of assembly, it can be seen that the frame part, which supports the corner plate 6, has been pushed in Fig. 2 from right to left to the frame part with the corner plate 1. A polygonal clamping disc 14, which has an oval recess 15 and the edge 16 of which is crimped (FIG. 3), has been placed over the two projections 11, 13, the largest diameter of the recess 15 being larger than the greatest distance between the projections 11, 13 in the area of their flanges 12.

Durch Verdrehen der Klemmscheibe 14 mittels eines Schlüssels 17, im Sinne des Pfeiles F werden die Vorsprünge 11, 13 zueinander gezogen und die beiden Zargenteile werden so miteinander fest verbunden. Die zwischen den Vorsprüngen 11,013 und der Ausnehmung 15 der Klemmscheibe 14 wirksame Reibung hält die Klemmscheibe 14 in ihrer Fixierlage fest. Durch die Ausbildung der Vorsprünge 11, 13 wird dabei die Klemmscheibe 14 gegen die beiden Eckplatten 1, 6 gepreßt, was eine hervorragende Fixierung der Klemmscheibe und somit der Zargenteile in ihrer Ebene bewirkt.By turning the clamping disc 14 by means of a key 17, in the direction of arrow F, the projections 11, 13 are pulled toward one another and the two frame parts are thus firmly connected to one another. The effective friction between the projections 11,013 and the recess 15 of the clamping disk 14 holds the clamping disk 14 in its fixing position. Due to the design of the projections 11, 13, the clamping disc 14 is pressed against the two corner plates 1, 6, which causes an excellent fixation of the clamping disc and thus the frame parts in their plane.

Der Schlüssel 17 wird bevorzugt gekröpft ausgebildet, wobei Form und Größe seines Maules 18 der Vertiefung 19 der Klemmscheibe 14 entsprechen. Dies ist in Fig. 2 dargestellt und ermöglicht einerseits, die Klemmfläche groß zu gestalten und andererseits, auch bei Arbeiten über Kopf die Klemmscheibe 14 sicher zu führen.The key 17 is preferably cranked, the shape and size of its mouth 18 corresponding to the recess 19 of the clamping disc 14. This is shown in FIG. 2 and on the one hand makes it possible to make the clamping surface large and on the other hand to securely guide the clamping disc 14 even when working overhead.

Wie besonders aus Fig. 2 ersichtlich, liegt die Spannrichtung (die Verbindungslinie der beiden Vorsprünge 11, 13) in der sich die beiden Zargenteile 20, 21 beim Verdrehen der Klemmscheibe 14 zueinander bewegen (von rechts nach links in Fig. 2), annähernd senkrecht zur Trennlinie der beiden Zargenteile. Dies bewirkt, daß die beiden Zargenteile bei etwaigen Toleranzen und auftretendem Spiel zwischen den beiden Führungen in einer vorgegebenen Richtung gegeneinander gepreßt werden, wodurch eine leichtere und genauere Justierung möglich ist.As can be seen particularly from FIG. 2, the tensioning direction (the connecting line of the two projections 11, 13) in which the two frame parts 20, 21 move relative to one another when the clamping disk 14 is rotated (from right to left in FIG. 2) is approximately vertical to the dividing line of the two frame parts. This has the effect that the two frame parts are pressed against one another in a predetermined direction in the event of tolerances and play occurring between the two guides, as a result of which an easier and more precise adjustment is possible.

Die Erfindung kann vielfach variiert werden, so kann die Spannscheibe 14 aus einer einfachen Scheibe ohne gebördeltem Rand bestehen und sie kann eine andere Form aufweisen. Es kann in Abhängigkeit von der Größe der Zarge auch mehr als nur ein Paar Vorsprünge 11, 13 vorgesehen sein und es können die Vorsprünge 11, 13 eine andere Form aufweisen. Wesentlich ist, daß die Vorsprünge 11, 13 durch Verdrehen eine Klemmscheibe 14 aneinander gezogen werden und daß sie mit zunehmendem Abstand von der Eckplatte zunehmende Entfernung voneinander aufweisen.The invention can be varied in many ways, so the clamping disk 14 can consist of a simple disk without a flanged edge and it can have a different shape. Depending on the size of the frame, more than just a pair of projections 11, 13 can also be provided, and the projections 11, 13 can have a different shape. It is essential that the projections 11, 13 are pulled together by twisting a clamping disk 14 and that they have an increasing distance from one another with increasing distance from the corner plate.

In einer einfachsten Variante ist es auch möglich, die Vorsprünge direkt an den Zargenteilen anzubringen, dies kann insbesondere bei Kunststoffenstern von Vorteil sein, bei denen auch die entsprechenden Führungen einstückig ausgeführt sind. Die Beschreibung bezieht sich auf Zargen, doch können mit der erfindungsgemäßen Verbindungsvorrichtung selbstverständlich auch Türrahmen, Fensterrahmen u. ähnl. Gebilde zusammengebaut werden.In a simplest variant, it is also possible to attach the projections directly to the frame parts, this can be particularly advantageous in the case of plastic windows in which the corresponding guides are also made in one piece. The description relates to frames, but of course with the connecting device according to the invention also door frames, window frames and. similar Structures to be assembled.

Claims (6)

  1. Corner connector for cases, door or window frames which are constructed of several profile sections and which in the area of the butt joint on their side panel facing the masonry incorporate guide surfaces projecting in places past the butt joint, which surfaces correspond to corresponding guide surfaces of the other profile section whereby the position of the two profile sections in relation one another is determined, at least one projection being provided on each profile section and corresponding projections being moved in relation to one another by rotating a clamping disk, and being retained in the end position determined by the guides and/or profile sections,
       characterized by the fact that, as is known in the case of corner connectors with movable clamping plates, a pair of projections (11, 13) are clamped jointly in each case, furthermore by the fact that the projections are undercut on the side facing away from the butt joint and by the fact the clamping disk (14) incorporates an oval recess (15) whose shortest diameter is smaller than the shortest distance between the undercuts of the two projections (11, 13) in the assembled state and whose maximum diameter is greater than the maximum distance between the projections in the assembled state.
  2. Corner connector in accordance with Claim 1, characterized by the fact that the projections (11, 13) possess at least approximately the shape of a circular arc on cutting planes parallel to the plane of the clamping disk (14).
  3. Corner connector in accordance with Claim 1 or 2, characterized by the fact that the projections (11, 13) each consist of an arc-shaped section of the corner plate (1, 6) which is bent up and whose now uppermost section is bent through 90°, so that it forms the undercut.
