Definitions
- the invention relates to a rectangular door leaf made of metal, in particular for a folding door, the door leaves of which are designed to be torsionally rigid and are cantilevered in pivot joints with a vertical pivot axis, each with a rectangular frame in the contour of the finished door leaf, the at least four frame webs made of rectangular profiles has, which extend flush along the four sides of the rectangle and define two mutually plane-parallel support surfaces, in which the frame webs extend with one of their sides, and with two rectangular cover plates, which completely cover the frame on both sides of the support surfaces of the frame and with the Frames are connected.
- the second cover plate must be spotted on the outside and Weld spots damage the outer skin of this cover plate. All of this has to be reworked. It has also proven to be disadvantageous that the material is distorted by spot welding, unless extraordinary care is taken.
- the object of the invention is to avoid the disadvantages for the cover plates caused by spot welding and to simplify the production of door leaves equipped with cover plates, in particular with the aim of making the door leaves lighter and more precise.
- the invention is characterized in that the cover plates are connected to the frame by gluing and that the frame webs are glued together to form a rigid frame.
- the frame is only glued by a light, simple connection, which is just sufficient to give the frame webs the support required for further processing to the door leaf so that the frame can be moved by hand without the risk that the individual frame webs can undesirably shift relative to their mutually aligned position in which they are connected to one another.
- the frame only finds its final hold for the stiffening by gluing it to the cover plates.
- Modern adhesives especially two-component adhesives, also offer a sufficiently firm bond for metals.
- the glue offers extensive adhesion, so that a higher dimensional stability is achieved, which allows lower material thicknesses to be used with the same stability and torsional rigidity. This in turn leads to the desired weight saving.
- Post-processing is not necessary when gluing, especially If the outer skin of the cover plates is not impaired by the gluing, it can therefore be completely and completely prepared before the gluing and then requires no further processing. This is an extremely simplification of the manufacturing process.
- the frame webs that extend along the long sides are connected to the other frame webs and possibly also to the frame rungs by gluing to form a stable frame.
- the invention allows the use of aluminum for the cover plates and / or the frame webs and optionally also the frame rungs.
- the additional dimensional stability achieved by the glue makes up for the lower stiffness of the aluminum, so that, if at all, the material thickness required for aluminum is only slightly less than for steel. Overall, additional weight savings are achieved through the use of aluminum.
- the gluing can be carried out by extending over the entire surfaces lying on the one hand from the frame and from the cover plate on the other. But this is generally not necessary.
- the procedure is expediently such that the frame webs are first put together to form the frame, so that the cover plates are then glued on.
- FIG. 1 designates a six-wing folding door, the left wing part of the door leaves 3, 4 and 5 and the right wing part of the door leaves 7 to 9. All door leaves are designed to be torsionally rigid, have the shape of an elongated, upright rectangle and are supported in pivot joints, such as pivot joints 14, 16, so that they can be pivotably supported about vertical axes 17, 18. The door leaves 3 to 5 and 7 to 9 are therefore only carried by the swivel joints and are neither hung on the upper edge nor supported on the lower edge.
- the door leaf 4 is shown in FIG. 3, but without fittings, that is to say without pivot joints.
- the door leaf consists of a rectangular frame 25, two rectangular cover plates 26, 27 and two inserted sheet metal strips 28, 29.
- the frame 25 in turn consists of four frame webs 30, 31, 32, 33 and a frame rung 54.
- the frame webs and the frame rungs consist of Rectangular profile.
- the frame webs 30 and 32 extend along the longitudinal sides of the rectangle, the frame webs 31, 33 extend in between along the rectangular narrow sides and the frame rung 54 extends between the frame webs 31, 33 on the one hand and between the frame webs 30, 32 on the other hand parallel to the frame webs 31, 33 .
- the frame webs define two flat support surfaces 34, 35 in which they each extend with one of their sides, for example the sides facing the viewer for the support surface 35 in FIG. 3.
- the frame webs are glued to one another along the end faces of the frame webs 31, 33 and the frame rung 54.
- the prefabricated cover plates 26, 27 are glued to the frame 25.
- the cover plates 26, 27 are dimensioned to protrude along the long sides of the rectangle and are bent at right angles around the frame 25.
- the protruding strips 40, 41, 42 and the fourth strip not visible in the drawing extend almost to the center of the frame 43.
- a slot 44 remains free on each side between the angled strips 40, 41, 42 an inserted rubber strip 45 is filled.
- the slot that is not visible in the drawing and the corresponding rubber strip are designed in exactly the same way as the visible slot 44 and the rubber strip 45.
- the cover plates 26, 27 protrude beyond the frame 25 along the short sides of the rectangle. This creates a free gap 46, 47 on both narrow ends of the door leaf 4, which is filled by a form-fitting metal strip 28, 29 made of a U-profile. As can be seen from FIG. 4 above, the open side of the profile points outwards.
- the sheet metal strips 28, 29 can be clamped there in a form-fitting manner or also glued in.
- the gluing for the cover plates can extend over the entire contact surfaces of the contact surfaces 34, 35.
- the contact surfaces of the frame are formed by the relevant side surfaces of the frame webs 30-33 and the frame rung 54.
- the contact surface of the frame facing the viewer of FIG. 3 is designated 57.
- the contact surfaces of the cover plates 26, 27 are defined by the outline of the associated contact surface of the frame.
- the procedure for manufacturing the door leaf is as follows: First, the frame webs 30, 31, 32, 33 and the frame rung 54 are connected to one another by gluing. It is sufficient if the connection ensures the stability of the frame required for further processing. Then the cover plates are glued on.
- the cover plate 27 is pressed onto the frame and glued in the desired orientation and then the other frame side and the other cover plate 26 are moved accordingly. Then the rubber strips 45 and the opposite rubber strip are drawn in and the metal strips 28 and 29 are inserted and clamped or glued to the frame.

Abstract
Description
Die Erfindung betrifft ein rechteckiges Türblatt aus Metall, insbesondere für eine Falttür, deren Türblätter verwindungssteif ausgebildet sind und in Schwenkgelenken mit vertikaler Schwenkachse zu jeweils mehreren aneinander freitragend gelagert sind, mit einem rechteckigen Rahmens in der Kontur des fertigen Türblattes, der mindestens vier Rahmenstege aus Rechteckprofilen aufweist, die sich bündig entlang der vier Rechteckseiten erstrecken und zwei zueinander planparallele Auflageflächen definieren, in denen sich die Rahmenstege mit jeweils einer ihrer Seiten erstrecken, und mit zwei rechteckigen Deckblechen, die den Rahmen vollständig abdeckend beidseitig auf die Auflageflächen des Rahmens gelegt und mit dem Rahmen verbunden sind.The invention relates to a rectangular door leaf made of metal, in particular for a folding door, the door leaves of which are designed to be torsionally rigid and are cantilevered in pivot joints with a vertical pivot axis, each with a rectangular frame in the contour of the finished door leaf, the at least four frame webs made of rectangular profiles has, which extend flush along the four sides of the rectangle and define two mutually plane-parallel support surfaces, in which the frame webs extend with one of their sides, and with two rectangular cover plates, which completely cover the frame on both sides of the support surfaces of the frame and with the Frames are connected.
Bei einer solchen Falttür, wie sie aus der DE-PS 3468473 bekannt ist, sind für jede Seite drei Türblätter freitragend aneinandergelenkt. Diese drei Türblätter können zum Öffnen ziehharmonikaartig zu einem Paket zusammengefaltet werden. Für die Funktion einer solchen Falttür ist es wichtig, daß die einzelnen Türblätter verwindungssteif und möglichst leicht ausgebildet sind. Bei der bekannten Falttür bestehen diese Türblätter aus Stahlblech mit einem Stahlrahmen und die Deckbleche sind auf den Stahlrahmen durch Punktschweißen befestigt. Für das erste Deckblech kann die Punktschweißung von innen vorgenommen werden. Wenn man sie entsprechend differenziert bemißt und das Deckblech eine hinreichende Stärke hat, dann ist es möglich, die Punktschweißung so auszuführen, daß sie die freiliegende Außenseite des betreffenden Deckbleches nicht beschädigt. Dem liegt aber eine diffizile, kostspielige Arbeitstechnik zugrunde.In such a folding door, as is known from DE-PS 3468473, three door leaves are cantilevered for each side. These three door leaves can be folded into an accordion-like package to open them. For the function of such a folding door, it is important that the individual door leaves are torsionally rigid and as light as possible. In the known folding door, these door leaves consist of sheet steel with a steel frame and the cover plates are fixed to the steel frame by spot welding. For the first cover plate, spot welding can be carried out from the inside. If one measures them appropriately differentiated and the cover plate is of sufficient strength, then it is possible to carry out the spot welding in such a way that it does not damage the exposed outside of the cover plate in question. However, this is based on a difficult, expensive work technique.
Das zweite Deckblech muß von außen aufgepunktet werden und Schweißstellen beschädigen die Außenhaut dieses Deckbleches. Das muß alles nachgearbeitet werden. Dabei hat sich auch als nachteilig erwiesen, daß sich durch die Punktverschweißung das Material verzieht, wenn nicht außerordentliche Sorgfalt aufwendet wird.The second cover plate must be spotted on the outside and Weld spots damage the outer skin of this cover plate. All of this has to be reworked. It has also proven to be disadvantageous that the material is distorted by spot welding, unless extraordinary care is taken.
Aufgabe der Erfindung ist es, die durch die Punktschweißung bedingten Nachteile für die Deckbleche zu vermeiden und die Herstellung von mit Deckblechen ausgestatteten Türblättern zu vereinfachen, insbesondere mit dem Ziel, die Türblätter leichter und exakter auszugestalten.The object of the invention is to avoid the disadvantages for the cover plates caused by spot welding and to simplify the production of door leaves equipped with cover plates, in particular with the aim of making the door leaves lighter and more precise.
Die Erfindung ist dadurch gekennzeichnet, daß die Deckbleche mit dem Rahmen durch Verklebung verbunden sind und daß die Rahmenstege durch Verklebung zu einem in sich steifen Rahmen miteinander verbunden sind.The invention is characterized in that the cover plates are connected to the frame by gluing and that the frame webs are glued together to form a rigid frame.
Die Verklebung des Rahmens erfolgt nur durch eine leichte, einfache Verbindung, die gerade ausreicht, den Rahmenstegen den für die Weiterverarbeitung zum Türblatt erforderlichen Halt aneinander zu geben, so daß man den Rahmen für sich von Hand versetzen kann, ohne daß die Gefahr besteht, daß die einzelnen Rahmenstege sich gegenüber ihrer zueinander ausgerichteten Position, in der sie miteinander verbunden sind, unerwünscht verschieben können. Den für die Versteifung endgültigen Halt findet der Rahmen erst durch die Verklebung mit den Deckblechen.The frame is only glued by a light, simple connection, which is just sufficient to give the frame webs the support required for further processing to the door leaf so that the frame can be moved by hand without the risk that the individual frame webs can undesirably shift relative to their mutually aligned position in which they are connected to one another. The frame only finds its final hold for the stiffening by gluing it to the cover plates.
Moderne Klebstoffe, insbesondere Zweikomponentenkleber, bieten auch für Metalle eine hinreichend feste Verklebung. Die Verklebung bietet im Gegensatz zur Punktschweißung eine flächenhafte Haftung, so daß eine höhere Formstabilität erzielt wird, die es gestattet, bei gleicher Stabilität und Verwindungssteifheit geringere Materialstärken einzusezten. Das führt wiederum zu der gewünschten Gewichtsersparnis. Nachbearbeitungen sind bei Verklebung nicht erforderlich, insbesondere wird die Außenhaut der Deckbleche durch die Verklebung nicht beeinträchtigt, kann also vor der Verklebung fix und fertig vorgearbeitet sein und bedarf dann keiner Nachbearbeitung mehr. Das ist eine außerordentlich Vereinfachung des Fertigungsverfahrens.Modern adhesives, especially two-component adhesives, also offer a sufficiently firm bond for metals. In contrast to spot welding, the glue offers extensive adhesion, so that a higher dimensional stability is achieved, which allows lower material thicknesses to be used with the same stability and torsional rigidity. This in turn leads to the desired weight saving. Post-processing is not necessary when gluing, especially If the outer skin of the cover plates is not impaired by the gluing, it can therefore be completely and completely prepared before the gluing and then requires no further processing. This is an extremely simplification of the manufacturing process.
Zweckmäßig geht man von einem Türblatt aus, bei dem die sich entlang der Schmalseiten erstreckenden beiden Rahmenstege und eventuell zusätzlich dazwischen und parallel dazu angeordnete Rahmensprossen zwischen den sich entlang der langen Seiten erstreckenden Rahmenstegen angeordnet sind.It is expedient to start from a door leaf in which the two frame webs extending along the narrow sides and possibly additionally in between and parallel to them frame rungs are arranged between the frame webs extending along the long sides.
In einem solchen Fall empfiehlt es sich, daß die sich entlang der langen Seiten erstreckenden Rahmenstege mit den übrigen Rahmenstegen ung gegebenenfalls auch den Rahmensprossen durch Verklebung zu einem in sich stabilen Rahmen miteinander verbunden sind.In such a case, it is recommended that the frame webs that extend along the long sides are connected to the other frame webs and possibly also to the frame rungs by gluing to form a stable frame.
Die Erfindung gestattet den Einsatz von Aluminium für die Deckbleche und/oder die Rahmenstege und gegebenenfalls auch die Rahmensprossen. Die durch die Verklebung erzielte zusätzliche Formstabilität macht die geringere Steifigkeit des Aluminiums wett, so daß man, wenn überhaupt, nur um geringes stärkere Materialstärken bei Aluminium benötigt als bei Stahl. Insgesamt erzielt man durch den Einsatz des Aluminiums eine zusätzliche Gewichtsersparnis.The invention allows the use of aluminum for the cover plates and / or the frame webs and optionally also the frame rungs. The additional dimensional stability achieved by the glue makes up for the lower stiffness of the aluminum, so that, if at all, the material thickness required for aluminum is only slightly less than for steel. Overall, additional weight savings are achieved through the use of aluminum.
Man kann die Verklebung ausführen, indem sie sich über die gesamten Flächen erstreckt, die vom Rahmen einerseits und vom Deckblech andererseits aufeinanderliegen. Das ist aber im allgemeinen nicht nötig.The gluing can be carried out by extending over the entire surfaces lying on the one hand from the frame and from the cover plate on the other. But this is generally not necessary.
Zur Herstellung eines solchen Türblattes verfährt man zweckmäßig derart, daß zunächst die Rahmenstege zum Rahmen zusammengestellt werden, daß dann die Deckbleche aufgeklebt werden.To produce such a door leaf, the procedure is expediently such that the frame webs are first put together to form the frame, so that the cover plates are then glued on.
Weitere Merkmale der Erfindung sind Gegenstand der übrigen Unteransprüche.Further features of the invention are the subject of the remaining subclaims.
Die Erfindung wird nun anhand der beigefügten Zeichnung näher erläutert.The invention will now be explained in more detail with reference to the accompanying drawing.

Gemäß Figur 1 ist mit 1 eine sechsflügelige Falttür bezeichnet, deren linker Flügelteil die Türblätter 3, 4 und 5 und deren rechter Flügelteil die Türblätter 7 bis 9 umfaßt. Alle Türblätter sind verwindungssteif ausgebildet, haben die Form eines langgestreckten, aufrechten Rechteckes und sind in Schwenkgelenken, wie zum Beispiel den Schwenkgelenken 14, 16 um vertikale Achsen 17, 18 freitragend schwenkbar gelagert. Die Türblätter 3 bis 5 und 7 bis 9 werden also nur durch die Schwenkgelenke getragen und sind weder am oberen Rand aufgehängt noch am unteren Rand abgestützt.According to Figure 1, 1 designates a six-wing folding door, the left wing part of the
Oben befindet sich lediglich eine Führungsschiene 20, in der die Türblätter mittels der Führungsrollen 21, 22 geführt sind. Diese Führungsrollen haben keine tragende Funktion. In Offenstellung können die Türblätter wie aus Figur 2 ersichtlich zickzackartig zu Paketen zusammengefaltet werden.At the top there is only a
In Figur 3 ist das Türblatt 4, allerdings ohne Beschläge, also ohne Schwenkgelenke, dargestellt. Das Türblatt besteht aus einem rechteckigen Rahmen 25, zwei beidseitig aufgesetzten rechteckigen Deckblechen 26, 27 und zwei eingesetzten Blechstreifen 28, 29. Der Rahmen 25 seinerseits besteht aus vier Rahmenstegen 30, 31, 32, 33 und einer Rahmensprosse 54. Die Rahmenstege und die Rahmensprossen bestehen aus Rechteckprofil. Die Rahmenstege 30 und 32 erstrecken sich entlang der Rechtecklängsseiten, die Rahmenstege 31, 33 erstrecken sich dazwischen entlang der Rechteckschmalseiten und die Rahmensprosse 54 erstreckt sich zwischen den Rahmenstegen 31, 33 einerseits und zwischen den Rahmenstegen 30, 32 andererseits parallel zu den Rahmenstegen 31, 33.The
Die Rahmenstege definieren zwei ebene Auflageflächen 34, 35 in denen sie sich mit jeweils einer ihrer Seite erstrecken, beispielsweise den in Figur 3 dem Beschauer zugekehrten Seiten für die Auflagefläche 35. Die Rahmenstege sind miteinander verklebt entlang der Stirnseiten der Rahmenstege 31, 33 und der Rahmensprosse 54.The frame webs define two
Auf den Rahmen 25 sind die vorgefertigten Deckbleche 26, 27 aufgeklebt. Die Deckbleche 26, 27 sind entlang der langen Rechteckseiten überstehend bemessen und um den Rahmen 25 rechtwinklig geknickt. Die dadurch überstehenden Streifen 40, 41, 42 und der vierte in der Zeichnung nicht sichtbare Streifen erstrecken sich fast bis zur Rahmenmitte 43. Dadurch bleibt zwischen den abgewinkelten Streifen 40, 41, 42 ... auf jeder Seite ein Schlitz 44 frei, der durch eine eingelegte Gummileiste 45 ausgefüllt ist. Der in der Zeichnung nicht sichtbare Schlitz und die entsprechende Gummileiste sind genauso ausgebildet wie der sichtbare Schlitz 44 und die Gummileiste 45.The
Entlang der kurzen Rechteckseiten stehen die Deckbleche 26, 27 über den Rahmen 25 über.

Die offene Seite des Profils weist, wie aus Figur 4 oben ersichtlich, nach außen. Die Blechstreifen 28, 29 können dort formschlüssig passend eingeklemmt oder auch eingeklebt sein.The
Die Verklebung für die Deckbleche kann sich über die ganzen Kontaktflächen der Auflageflächen 34, 35 erstrecken. Die Kontaktflächen des Rahmens sind durch die betreffenden Seitenflächen der Rahmenstege 30 - 33 und der Rahmensprosse 54 gebildet. Die dem Beschauer von Figur 3 zugekehrte Kontaktfläche des Rahmens ist mit 57 bezeichnet. Die Kontaktflächen der Deckbleche 26, 27 sind definiert durch den Umriß der zugehörigen Kontaktfläche des Rahmens.The gluing for the cover plates can extend over the entire contact surfaces of the contact surfaces 34, 35.
