Definitions
- the invention relates to a corner connection for hollow profiles made of light metal, in particular for binding spacer frames of an insulating glass pane, consisting of a metallic and in cross-section approximately U-shaped corner connection angle, the legs of which are adapted to the inner cross section of the hollow profile and whose curved, incised corner area opposite the side surfaces of the legs is raised and forms stops for the hollow profiles to be pushed on.
- Corner connection angles from which the invention is based have become known, for example, from DE-B-2 532 896 and DE-U-7 909 265.
- a sheet metal strip is assumed, which is provided with notches, punchings, incisions and the like, is embossed in a U-shaped cross-section along its longitudinal direction and is finally bent to an angle.
- the legs of the corner connection angle formed thereby have an outer contour which corresponds to the inner contour of the hollow profile into which the individual leg is to be inserted or pressed.
- the hollow profiles are cut transversely to their longitudinal axis.
- the front edges meet in a known manner against a trained corner area of the corner connection angle.
- this corner area is shaped without cutting in the manner of a console, in which there is a slot which runs from the inner corner of the angle piece in the direction of the apex thereof.
- the aim of this measure is to produce a corner connection angle which deviates from 90 ° and which still has sufficient rigidity in the desired angular position of its legs.
- the known corner connection angles have the disadvantage that they have to be unstable, especially in the curved corner region, in order to be able to be changed with regard to the angularity.
- the object of the invention is accordingly to design the corner connection angle in such a way that it can be produced easily and accurately in shape and therefore in large numbers using simple deformation tools, whereby it performs a rigid and stabilizing function for the frame to be formed.
- the solution to the problem according to the invention is that the side walls of the U-shaped legs are arranged to overlap one another in the corner region of the corner connection angle, by a wall region adjacent to an incision extending transversely to the longitudinal axis of the leg is embossed by the measure of its wall thickness from the original plane and, after the angle has been bent, comes to rest on the other wall area that remains undeformed and adjoins the incision, the edges of the overlap forming the stop edges for the hollow profiles to be pushed on.
- a corner connection angle designed in this way can be automatically produced and deformed by the belt in a particularly simple manner. This is because it is possible to make the incision according to the invention with the adjacent embossed section in the same work step as the preparation for the later U-shaped profiling of the corner connection angle.
- the wall areas adjacent to the incisions reach behind and form a geometrically defined overlap that projects beyond the side surfaces of the legs by the measure of the wall thickness.
- the edges of this overlap also form stop edges for the hollow profiles to be pushed onto the legs.
- the corner connection angle in the outside of the curved corner region has a bead-like impression which is approximately V-shaped in cross section, extends along the longitudinal axis and runs into the web surface of the legs. Similar stabilization measures are known.
- the invention prefers an indentation directed inwards from the outside, by means of which 2/5 of the adjacent angle legs are each deformed.
- a corner connection angle produced in this way is dimensionally stable and therefore particularly suitable for stabilizing a light metal frame. Regardless of this, the adjoining edges of the overlapping wall sections can also be soldered in the usual way.
- the invention provides that the free edge regions of the legs are tapered in a wedge shape. In this way, in view of the rigidity of the corner connection angle according to the invention, the easy pushing of the hollow profiles onto the legs is facilitated.
- the corner connection angle 1 shown in FIG. 1 has two legs 2, 3 produced by bending, between which a curved corner region 4 is provided.
- the corner area 4 is formed laterally by overlaps 8 of wall areas 13, 14 (see FIGS. 3 and 4). These overlaps 8 have stop edges 7 on which the end edges of the hollow profiles 5, 6 come to rest.
- the rigidity of the corner connection angle 1 is essentially determined by a bead-shaped indentation 10, which is embossed along the central longitudinal plane from the outside into the curvature area 4 of the corner connection angle 1 such that this indentation 10 2/5 of the legs 2, 3 also includes. This non-cutting deformation also improves the firm contact of the wall areas 13, 14 forming the overlap 8.
- the blank 15 for the corner connection angle 1 (see FIG. 5) is first provided at the edge with incisions 12 extending transversely to the longitudinal direction.
- a wall area 13 adjoining this incision 12 is offset by the measure of its wall thickness, whereas the other adjoining wall area 14 remains undeformed.
- These wall areas 13, 14 are part of the U-shaped angled side walls of the legs 2, 3. If one now bends the U-shaped profile shown in FIG. 4 in such a way that the shape shown in FIG. 1 arises, the offset wall area engages 13 the undeformed wall area 14. Both lie against one another in the bent position (FIG. 4) and thus form the overlap 8.
- the area of the overlap 8 can additionally be stabilized by spot welding on both sides.
- the corner bracket according to the invention is designed so that it can be made from different materials, which can also be solderable.
- the corner connection angles are stamped out step by step from a sheet metal strip 17, for the advance of which the driving holes 16 are provided.
- the individual blank 15 is initially formed on the end face by punched-out portions 18 and laterally by separating slots 19. With the dash-dotted lines 20 parallel to the separating slots 19, bending edges are shown, around which the U-shaped bending of the legs 2, 3 takes place in a further working step, not shown.
- the incisions 12 extend from the separating slots 19, the base 21 of which is semicircular in order to avoid cracking during the later bending.
- the depth of the incisions 12 is smaller than the depth of the adjacent expression 13, the surface area of which is delimited by broken lines 22 in FIG. 6.
- the individual blank 15 is separated from the rest of the sheet metal strip 17 by punching along the dash-dotted line 23.

Abstract
Description
Die Erfindung bezieht sich auf eine Eckverbindung für Hohlprofile aus Leichtmetall, insbesondere zur Bindung von Abstandhalterrahmen einer Isolierglasscheibe, bestehend aus einem metallischen und im Querschnitt etwa U-förmigen Eckverbindungswinkel, dessen Schenkel dem Innenquerschnitt des Hohlprofiles angepasst sind und dessen gekrümmter, einen Einschnitt aufweisender Eckenbereich gegenüber den Seitenflächen der Schenkel erhaben ausgebildet ist und Anschläge für die aufzuschiebenden Hohlprofile bildet.The invention relates to a corner connection for hollow profiles made of light metal, in particular for binding spacer frames of an insulating glass pane, consisting of a metallic and in cross-section approximately U-shaped corner connection angle, the legs of which are adapted to the inner cross section of the hollow profile and whose curved, incised corner area opposite the side surfaces of the legs is raised and forms stops for the hollow profiles to be pushed on.
Eckverbindungswinkel, von denen die Erfindung ausgeht, sind beispielsweise durch die DE-B-2 532 896 und das DE-U-7 909 265 bekannt geworden. In beiden Fällen wird von einem Blechstreifen ausgegangen, der mit Einkerbungen, Asstanzungen, Einschnitten und dgl. versehen, entlang seiner Längsrichtung im Querschnitt U-förmig geprägt und schliesslich zu einem Winkel gebogen wird. Die dadurch gebildeten Schenkel des Eckverbindungswinkels weisen eine Aussenkontur auf, die der Innenkontur des Hohlprofiles entspricht, in welche der einzelne Schenkel eingeschoben oder eingepresst werden soll. Demzufolge sind die Hohlprofile quer zu ihrer Längsachse abgeschnitten. Ihre Stirnränder stossen in bekannter Weise an einen ausgebildeten Eckbereich des Eckverbindungswinkels.Corner connection angles from which the invention is based have become known, for example, from DE-B-2 532 896 and DE-U-7 909 265. In both cases, a sheet metal strip is assumed, which is provided with notches, punchings, incisions and the like, is embossed in a U-shaped cross-section along its longitudinal direction and is finally bent to an angle. The legs of the corner connection angle formed thereby have an outer contour which corresponds to the inner contour of the hollow profile into which the individual leg is to be inserted or pressed. As a result, the hollow profiles are cut transversely to their longitudinal axis. The front edges meet in a known manner against a trained corner area of the corner connection angle.
Im Falle der DE-B-2 532 896 wird dieser Eckbereich nach Art einer Konsole spanlos geformt, in der sich ein Schlitz befindet, der von der Innenecke des Winkelstückes in Richtung auf dessen Scheitel verläuft. Mit dieser Massnahme will man erreichen, einen von 90° abweichenden Eckverbindungswinkel herzustellen, der in der gewünschten Winkelstellung seiner Schenkel eine noch ausreichende Steifigkeit besitzt.In the case of DE-B-2 532 896, this corner area is shaped without cutting in the manner of a console, in which there is a slot which runs from the inner corner of the angle piece in the direction of the apex thereof. The aim of this measure is to produce a corner connection angle which deviates from 90 ° and which still has sufficient rigidity in the desired angular position of its legs.
Die vorbekannten Eckverbindungswinkel haben den Nachteil, dass sie besonders im gekrümmten Eckbereich instabil sein müssen, um veränderbar bezüglich der Winkeligkeit sein zu können.The known corner connection angles have the disadvantage that they have to be unstable, especially in the curved corner region, in order to be able to be changed with regard to the angularity.
Die Aufgabe der Erfindung besteht demgemäss darin, den Eckverbindungswinkel so auszugestalten, dass er sich mit einfachen Verformungswerkzeugen leicht und formgenau und damit in grosser Stückzahl herstellen lässt, wobei er eine starre und für den zu bildenden Rahmen stabilisirende Funktion ausübt.The object of the invention is accordingly to design the corner connection angle in such a way that it can be produced easily and accurately in shape and therefore in large numbers using simple deformation tools, whereby it performs a rigid and stabilizing function for the frame to be formed.
Ausgehend von der DE-B-2 532 896 besteht die erfindungsgemässe Lösung der gestellten Aufgabe darin, dass die Seitenwände der U-förmigen Schenkel im Eckbereich des Eckverbindungswinkels einander überlappend angeordnet sind, indem ein an einen quer zur Längsachse des Schenkels sich erstreckenden Einschnitt angrenzender Wandbereich um das Mass seiner Wanddicke aus der ursprünglichen Ebene herausgeprägt ist und nach dem Biegen des Winkels an dem unverformt bleibenden anderen, an den Einschnitt angrenzenden Wandbereich zur Anlage kommt, wobei die Ränder der Überlappung die Anschlagkanten für die aufzuschiebenden Hohlprofile bilden.Starting from DE-B-2 532 896, the solution to the problem according to the invention is that the side walls of the U-shaped legs are arranged to overlap one another in the corner region of the corner connection angle, by a wall region adjacent to an incision extending transversely to the longitudinal axis of the leg is embossed by the measure of its wall thickness from the original plane and, after the angle has been bent, comes to rest on the other wall area that remains undeformed and adjoins the incision, the edges of the overlap forming the stop edges for the hollow profiles to be pushed on.
Ein in dieser Weise ausgestalteter Eckverbindungswinkel lässt sich in besonders einfacher Weise vom Band automatisch herstellen und verformen. Es ist nämlich die Möglichkeit gegeben, den erfindungsgemässen Einschnitt mit dem angrenzenden herausgeprägten Abschnitt im gleichen Arbeitsgang wie die Vorbereitung zur späteren U-förmigen Profilierung des Eckverbindungswinkels vorzunehmen.A corner connection angle designed in this way can be automatically produced and deformed by the belt in a particularly simple manner. This is because it is possible to make the incision according to the invention with the adjacent embossed section in the same work step as the preparation for the later U-shaped profiling of the corner connection angle.
Biegt man nun den U-förmigen Zuschnitt zur Bildung der meist 90° aufeinanderstehenden Schenkel ab, dann hintergreifen sich die an die Einschnitte angrenzenden Wandbereiche und bilden eine geometrisch bestimmte Überlappung, die um das Mass der Wanddicke über die Seitenflächen der Schenkel erhaben hinausragt. Die Ränder dieser Überlappung bilden zugleich Anschlagkanten für die auf die Schenkel aufzuschiebenden Hohlprofile.If you now bend the U-shaped blank to form the legs, which usually stand at 90 ° on top of each other, then the wall areas adjacent to the incisions reach behind and form a geometrically defined overlap that projects beyond the side surfaces of the legs by the measure of the wall thickness. The edges of this overlap also form stop edges for the hollow profiles to be pushed onto the legs.
Es hat sich als vorteilhaft erwiesen, den Grund des Einschnittes halbkreisförmig zu gestalten. Dadurch werden unerwünschte Rissbildungen beim Ausprägen des dem Einschnitt benachbarten Wandabschnittes vermieden. Aus dem gleichen Grund empfiehlt es sich, die Tiefe des Einschnittes kleiner als die Tiefe des benachbarten und aus seiner ursprünglichen Ebene herausgeprägten Wandbereiches zu dimensionieren.It has proven to be advantageous to make the base of the incision semicircular. This avoids undesirable crack formation when stamping the wall section adjacent to the incision. For the same reason, it is advisable to dimension the depth of the incision to be smaller than the depth of the adjacent wall area which is embossed from its original plane.
Im Rahmen einer Ausgestaltung der Erfindung ist vorgesehen, dass der Eckverbindungswinkel in der Aussenseite des gekrümmten Eckenbereiches eine im Querschnitt etwa v-förmige, entlang der Längsachse sich erstreckende und in die Stegfläche der Schenkel auslaufende sickenartige Einprägung aufweist. Ähnliche Stabilisierungsmassnahmen sind zwar bekannt. Die Erfindung bevorzugt eine von der Aussenseite nach innen gerichtete Einprägung, durch die 2/5 der angrenzenden Winkelschenkel jeweils verformt sind.In the context of an embodiment of the invention, it is provided that the corner connection angle in the outside of the curved corner region has a bead-like impression which is approximately V-shaped in cross section, extends along the longitudinal axis and runs into the web surface of the legs. Similar stabilization measures are known. The invention prefers an indentation directed inwards from the outside, by means of which 2/5 of the adjacent angle legs are each deformed.
Ein so hergestellter Eckverbindungswinkel ist formsteif und somit für die Stabilisierung eines Leichtmetallrahmens besonders geeignet. Dessen ungeachtet können die aneinandergrenzenden Kanten der sich überlappenden Wandabschnitte auch in üblicher Weise verlötet sein.A corner connection angle produced in this way is dimensionally stable and therefore particularly suitable for stabilizing a light metal frame. Regardless of this, the adjoining edges of the overlapping wall sections can also be soldered in the usual way.
Schliesslich sieht die Erfindung vor, dass die freien Randbereiche der Schenkel keilförmig sich verjüngend ausgebildet sind. Auf diese Weise wird angesichts der Steifigkeit des erfindungsgemässen Eckverbindungswinkels das leichte Aufschieben der Hohlprofile auf die Schenkel erleichtert.Finally, the invention provides that the free edge regions of the legs are tapered in a wedge shape. In this way, in view of the rigidity of the corner connection angle according to the invention, the easy pushing of the hollow profiles onto the legs is facilitated.

Der in Fig. 1 dargestellte Eckverbindungswinkel 1 weist zwei durch Abbiegung erzeugte Schenkel 2, 3 auf, zwischen denen ein gekrümmter Eckenbereich 4 vorgesehen ist.The
Auf die Schenkel 2, 3 werden die Stirnbereiche von Hohlprofilen 5, 6 aus Leichtmetall aufgeschoben, so dass auf diese Weise ein geschlossener Rahmen gebildet werden kann. Zur Fixierung der Hohlprofile 5, 6 auf den Schenkeln 2, 3 sind herausgeprägte Vorsprünge 9 vorgesehen, die sich reibend an der Innenfläche der Hohlprofile 5, 6 abstützen.The end regions of
Der Eckenbereich 4 ist seitlich durch Überlappungen 8 von Wandbereichen 13, 14 (vgl. Figuren 3 und 4) gebildet. Diese Überlappungen 8 weisen Anschlagkanten 7 auf, an denen die Stirnränder der Hohlprofile 5, 6 zur Anlage kommen.The
Die Steifigkeit des Eckverbindungswinkel 1 wird wesentlich von einer sickenförmigen Einprägung 10 bestimmt, die entlang der Mittellängsebene von aussen her in den Krümmungsbereich 4 des Eckverbindungswinkels 1 so eingeprägt wird, dass diese Einprägung 10 2/5 der Schenkel 2, 3 mit erfasst.

Diese Wandbereiche 13, 14 sind Bestandteil der U-förmig abgewinkelten Seitenwände der Schenkel 2, 3. Wenn man nun das in Fig. 4 dargestelle U-förmig gestaltete Profil so biegt, dass die in Fig. 1 dargestellte Form entsteht, umgreift der abgesetzte Wandbereich 13 den unverformten Wandbereich 14. Beide liegen in der abgebogenen Stellung aneinander an (Fig. 4) und bilden somit die Überlappung 8.
