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 Rahmen, in der Kontur des fertigen Türblattes aus mindestens vier Rahmenstegen aus Rechteckprofil 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 self-supporting in pivot joints with a vertical pivot axis, each with a rectangular frame, in the contour of the finished door leaf comprising at least four frame bars made of rectangular profile 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 cover the frame completely 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. Spot welding can be carried out from the inside for the first cover plate. If you measure them appropriately differentiated and the cover plate has sufficient strength, then it is possible to carry out the spot welding so 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 die durch die Punktverschweißung das Material sich verzieht, wenn nicht außerordentliche Sorgfalt aufgewendet 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 warps due to the spot welding, unless extraordinary care is taken.

Aufgabe der Erfindung ist es, die durch die Punktschweißung bedingten Nachteile zu vermeiden und die Herstellung zu vereinfachen, insbesondere mit dem Ziel, das Türblatt leich­ter und exakter auszugestalten.The object of the invention is to avoid the disadvantages caused by spot welding and to simplify manufacture, in particular with the aim of making the door leaf lighter and more precise.

Die Erfindung ist dadurch gekennzeichnet, daß die Deckbleche mit dem Rahmen durch Verklebung verbunden sind und daß die Rahmenstege zum Rahmen nur miteinander verheftet sind.The invention is characterized in that the cover plates are connected to the frame by gluing and that the frame webs to the frame are only stitched together.

Unter Verheftung wird hier und im folgenden eine nur sehr leichte, einfache Verbindung verstanden, die gerade ausreicht, den Rahmenstegen den für die Weiterverarbeitung zum Türblatt erforderlichen Halt aneinander zu geben, so daß man den so durch Heftung verbundenen 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 verheftet sind, unerwünscht verschieben können. Den für die Versteifung end­gültigen Halt findet der Rahmen erst durch die Verklebung mit den Deckblechen.Here and below, stitching is understood to mean only a very light, simple connection, which is just sufficient to give the frame webs the support required for further processing to form the door leaf, so that the frame connected by stitching 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 stitched together. 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 einzusetzen. Das führt wiederum zu der gewünschten Gewichtsersparnis. Nachbe­arbeitungen sind bei Verklebung nicht erforderlich, insbe­ sondere 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 bonding, especially in particular, the outer skin of the cover plates is not adversely affected by the gluing, so it can be pre-finished 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 und gegebenenfalls auch den Rahmenspros­sen durch Punktschweißen zu einem in sich stabilen Rahmen mit-einander verheftet sind.In such a case, it is recommended that the frame webs extending along the long sides be stitched together with the other frame webs and possibly also the frame rungs by spot welding 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 of aluminum is less than that of 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 top of one another from the frame and from the cover plate on the other. In general, however, this is not necessary.

Zur Herstellung eines solchen Türblattes verfährt man zweck­mäßig derart, daß zunächst die Rahmenstege zum Rahmen zusam­mengeheftet werden, daß dann die Deckbleche aufgeklebt wer­ den unter Verwendung eines Klebers aus einer streichfähigen Kleberkomponente und einer sprühfähigen Aktivatorkomponente, die erst bei Kontakt miteinander klebaktiviert sind, daß da­zu mit der einen Komponente die eine Kontaktfläche des Rah­mens und mit der anderen Komponente die gegenüberliegenden Teile des zugehörigen Deckbleches beschichtet werden, daß dann die so präparierten Teile aufeinandergepreßt werden und daß dann mit der anderen Rahmenseite und dem anderen Deck­blech entsprechend verfahren wird.To produce such a door leaf one proceeds expediently in such a way that the frame webs are first tacked together to form the frame, so that the cover plates are then glued on using an adhesive consisting of a spreadable adhesive component and a sprayable activator component, which are only activated when they come into contact with one another, for this purpose that one contact surface of the frame is coated with the one component and the opposite parts of the associated cover plate are coated with the other component, that then the prepared parts are pressed together and then the other side of the frame and the other cover plate are moved accordingly.

Dabei empfiehlt es sich, daß die streichfähige Kleberkompo­nente in Schlangenlinien auf die eine Kontaktfläche gestri­chen und die Aktivatorkomponente auf die zugehörige andere Kontaktfläche, diese vollständig abdeckend gesprüht wird.It is recommended that the spreadable adhesive component is painted in serpentine lines on one contact surface and the activator component is sprayed onto the associated other contact surface, covering it completely.

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.

In der Zeichnung zeigt:

  • Figur 1 eine Falttür geschlossen von vorn gesehen,
  • Figur 2 stilisiert den Schnitt II aus Figur 1,
  • Figur 3 ein Türblatt aus Figur 1 und 2, jedoch der Übersicht halber ohne die Beschläge, teilweise aufgebrochen, und
  • Figur 4 die Ansicht gemäß dem Pfeil IV aus Figur 3, teilweise angeschnitten entsprechend dem Schnittpfeil III aus Figur 3.
The drawing shows:
  • FIG. 1 shows a folding door closed from the front,
  • FIG. 2 stylizes section II from FIG. 1,
  • 3 shows a door leaf from FIGS. 1 and 2, but for the sake of clarity without the fittings, partially broken open, and
  • FIG. 4 shows the view according to arrow IV from FIG. 3, partially cut away according to the sectional arrow III from FIG. 3.

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 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 pivoted freely 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.

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 guide rail 20 in which the door leaves are guided by means of the guide rollers 21, 22. These leadership roles have no supporting function. In the open position, as shown in FIG. 2, the door leaves can be folded into packages in a zigzag fashion.

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 door leaf 4 is shown in FIG. 3, however without fittings, that is to say without swivel joints. The door leaf consists of a rectangular frame 25, two rectangular cover plates 26, 27 and two inserted sheet metal strips 28, 29 on both sides. 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 narrow rectangular 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 .

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 flat support surfaces 34, 35 in which they each extend with one of their sides, for example the sides facing the viewer in FIG. 3 for the support surface 35. The frame webs are glued to one another along the end faces of the frame webs 31, 33 and the frame rung 54.

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 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. As a result, 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 formed in exactly the same way as the visible slot 44 and the rubber strip 45.

Entlang der kurzen Rechteckseiten stehen die Deckbleche 26, 27 über den Rahmen 25 über. Dadurch entsteht an beiden Schmalenden des Türblattes 4 ein freier Spalt 46, 47, der durch einen formschlüssig passenden Blechstreifen 28, 29 aus U-Profil ausgefüllt ist. 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, vorzugsweise sind sie je­ doch von außen lösbar an den Rahmen geschraubt.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 positively clamped or glued there, preferably they are each screwed to the frame from the outside.

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 adhesive 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.

Zur Herstellung des Türblattes verfährt man zweckmäßig wie folgt:
Zunächst werden die Rahmenstege 30, 31, 32, 33 und die Rah­mensprosse 54 miteinander durch Punktschweißen zusammengeheftet. Es genügt, wenn die Heftung die für die Weiterverarbeitung des Rahmens erforderliche Stabilität des­selben gewährleistet. Dann werden die Deckbleche aufgeklebt, und zwar unter Verwendung eines Klebers aus einer streichfä­higen Kleberkomponente und einer sprühfähigen Aktivator­komponente, die erst bei Kontakt miteinander klebaktiviert sind. Dazu wird mit der streichfähigen Kleberkomponente zu­nächst auf der einen Seite des Rahmens die Kontaktfläche 57 des Rahmens in Schlangenlinie 58 bestrichen. Zwischen den Schlangenwindungen bleiben also Stellen der Kontaktfläche frei. Die dieser Kontaktfläche 57 gegenüberliegende Kontakt­fläche des Deckbleches 27, die also definiert ist durch die Flächenausdehnung der Kontaktfläche 57, wird dann vollflächig, also lückenlos, mit der Aktivatorkomponente besprüht.The procedure for manufacturing the door leaf is as follows:
First, the frame webs 30, 31, 32, 33 and the frame rung 54 are tacked together by spot welding. It is sufficient if the stitching ensures the stability of the frame required for the further processing. The cover plates are then glued on, using an adhesive comprising a spreadable adhesive component and a sprayable activator component, which are only activated when they come into contact with one another. For this purpose, the contact surface 57 of the frame is first coated on the serpentine line 58 with the spreadable adhesive component on one side of the frame. Places of the contact surface remain between the snake turns. The contact surface of the cover plate 27 opposite this contact surface 57, which is therefore defined by the surface extension of the contact surface 57, is then sprayed with the activator component over the entire surface, that is to say without gaps.

Ist das geschehen, dann wird das Deckblech 27 in der ge­wünschten Ausrichtung auf den Rahmen gepreßt und verklebt und dann wird mit der anderen Rahmenseite und dem anderen Deckblech 26 entsprechend verfahren. Dann werden die Gummi­ leisten 45 und die gegenüberliegende Gummileiste eingezogen und die Blechstreifen 28 und 29 werden eingesetzt und am Rahmen festgeschraubt durch Schrauben, die von außen zugäng­lich und auch wieder lösbar sind.Once this has been done, 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 afford 45 and the opposite rubber strip and the sheet metal strips 28 and 29 are inserted and screwed to the frame by screws that are accessible from the outside and also releasable.

Als Kleber wird vorzugsweise der unter der Bezeichnung Pen­loc GZH von der Fa. Panacol-Elosol GmbH, Frankfurt vertrieb­ene Zweikomponenten-Strukturklebstoff eingesetzt. Dieser Klebstoff wird vom Hersteller wie folgt charakterisiert:The adhesive used is preferably the two-component structural adhesive sold under the name Penloc GZH by Panacol-Elosol GmbH, Frankfurt.
