Aufzugstüren bestehen in der Regel aus einer Anzahl von Türblättern, die wiederum ein- oder mehrschalig ausgebildet sein können. Bei der Herstellung dieser Türblätter sind die vielfältigen Sicherheitsanforderungen, die an Aufzüge und Aufzugstüren gestellt sind, zu berücksichtigen.Elevator doors usually consist of a number of door leaves, which in turn can be formed single or multi-shell. When making these door panels, the various safety requirements placed on elevators and lift doors must be taken into account.

Üblicherweise werden Türblätter für Aufzüge einschalig ausgebildet. Hierbei sei bspw. auf Aufzugstürblätter der Feuerschutzklasse E120 bzw. EW60 gemäß EN 81-58 verwiesen. Die verwendeten Türblätter, die regelmäßig aus Blech gefertigt sind, sind an den Stirnseiten mit Ausstreifungsprofilen versehen. Hierbei erfolgt das Verbinden der Ausstreifungsprofile mit dem Türblatt durch Verschweißen. Alternativ kann die Verbindung auch durch Nieten, Schrauben oder Kleben erfolgen.Usually, door leaves for elevators are formed einschalig. Here, for example, reference is made to lift door leaves of fire protection class E120 or EW60 according to EN 81-58. The door leaves used, which are regularly made of sheet metal, are provided on the front sides with Ausstreifungsprofilen. Here, the joining of Ausstreifungsprofile with the door leaf is done by welding. Alternatively, the connection can also be made by riveting, screwing or gluing.

Bei Aufzugstürblättern mit großer Breite ist es bekannt, aus Stabilitätsgründen Ausstreifungsprofile anzubringen, die vorzugsweise mittig angebracht und verschweißt werden.For elevator door leaves with a large width, it is known to attach Ausstreifungsprofile for stability reasons, which are preferably mounted centrally and welded.

Die Druckschrift DE 690 17 299 T2 beschreibt eine teleskopische Aufzugstüreinrichtung mit einer Tür für eine hohe Geschwindigkeit und eine Tür für eine niedrige Geschwindigkeit, wobei jede Tür an einem Paar voneinander beabstandeten Rollenanordnungen aufgehängt ist und die Rollenanordnungen entlang einer einzigen gemeinsamen Bahn laufen. Jede der Türen kann aus einer Tafel gebildet sein, die sechs rechtwinklige Biegekanten besitzt, von denen zwei einen vertikalen, U-förmigen Kanal bilden, der sich entlang eines Seitenrands der Tafel erstreckt und von denen vier eine vertikale Säule mit rechteckigem Querschnitt entlang dem entgegengesetzten Seitenrand der Tafel bilden, wobei die Säule einer Ecke benachbart offen ist, so dass der U-förmige Kanal der einen Tür in die Säule der anderen Tür eingreifen kann.The publication DE 690 17 299 T2 describes a telescopic elevator door assembly having a high speed door and a low speed door with each door spaced apart at a pair Roller assemblies is suspended and run the roller assemblies along a single common path. Each of the doors may be formed of a panel having six rectangular bending edges, two of which form a vertical U-shaped channel extending along a side edge of the panel, four of which have a vertical column of rectangular cross-section along the opposite side edge form the panel, wherein the column adjacent to a corner is open, so that the U-shaped channel of a door can engage in the pillar of the other door.

Aus der Druckschrift DE 102 07 482 A1 ist ein Türsegment mit einem im wesentlichen rechteckförmigen Querschnitt bekannt, der von zwei Hauptwandabschnitten und zwei Seitenwandabschnitten gebildet wird. Zur Vereinfachung der Herstellung ist das Türsegment aus zwei Teilen zusammengesetzt, die jeweils einen Hauptwandabschnitt aufweisen und durch integrierte Schnappelemente miteinander koppelbar sind. Die Türsegmente bestehen aus Blechteilen, die durch Biegen umgeformt wurden.From the publication DE 102 07 482 A1 a door segment is known having a substantially rectangular cross-section which is formed by two main wall sections and two side wall sections. To simplify the manufacture of the door segment is composed of two parts, each having a main wall portion and can be coupled together by integrated snap elements. The door segments consist of sheet metal parts that have been formed by bending.

Die aus dem Stand der Technik bekannten Türblätter sind hinsichtlich ihrer Stabilität nicht ausreichend. Hier setzt die Erfindung an.The door leaves known from the prior art are not sufficient in terms of their stability. This is where the invention starts.

Das erfindungsgemäße Aufzugstürblatt sieht vor, dass im Bereich mindestens einer Kante eine doppelte im wesentlichen C-förmige Umkantung vorgesehen ist. Diese doppelte Umkantung verleiht dem Türblatt eine hohe Stabilität und kann bspw. durch manuelles Umbiegen eingebracht werden. Zusätzliche Teile zur Verstärkung des Türblatts sind nicht erforderlich. Dies bietet nicht nur hinsichtlich Logistik und Lagerhaltung Vorteile sondern auch bei der Herstellung, da bei der Fertigung mit mehreren Teilen, diese zueinander positioniert und gehalten werden müssen.The elevator door leaf according to the invention provides that in the region of at least one edge a double substantially C-shaped folded edge is provided. This double fold gives the door leaf a high stability and can be introduced, for example. By manual bending. Additional parts to reinforce the door panel are not required. This offers not only in terms of logistics and warehousing advantages but also in the production since in the production with several parts, these must be positioned and held each other.

Die doppelte Umkantung ist im wesentlichen C-förmig ausgebildet. Diese C-Form bietet eine hohe Stabilität und kann einfach durch Umbiegen des Blechs erzielt werden. Dieses Umbiegen kann maschinell oder manuell erfolgen.The double fold is essentially C-shaped. This C-shape offers high stability and can be achieved simply by bending the sheet. This bending can be done by machine or manually.

Als Material für das Türblatt kommt üblicherweise Blech, wie bspw. Edelstahlblech oder Schwarzblech, zum Einsatz. Auch ein verzinktes Blech kann eingesetzt werden.As a material for the door leaf is usually sheet metal, such as. Stainless steel or black plate, used. Even a galvanized sheet can be used.

Es kann zusätzlich eine Verkleidung, wie bspw. ein Verkleidungsblech vorgesehen sein, um sowohl das äußere Erscheinungsbild den Anforderungen anzupassen als auch eine ausreichende Geräuschdämmung zu bewirken. Diese Verkleidung kann aus unterschiedlichen Materialien gefertigt sein, wobei vorzugsweise ein Edelstahlblech verwendet wird. Alternativ kann Aluminium, Glas, Kunststoff oder Holz eingesetzt werden.It may additionally be a cladding, such as. A cladding sheet be provided to both adapt the appearance of the requirements and to effect a sufficient noise insulation. This cover can be made of different materials, preferably a stainless steel sheet is used. Alternatively, aluminum, glass, plastic or wood can be used.

Zusätzlich kann im Bereich mindestens einer Kante des Aufzugstürblatts ein Kantenschutz vorgesehen sein. Dieser Kantenschutz kann durch Umbiegen des Blechs erfolgen, um scharfe Kanten zu vermeiden, so dass die Verletzungsgefahr verringert wird.In addition, edge protection may be provided in the region of at least one edge of the elevator door leaf. This edge protection can be done by bending the sheet to avoid sharp edges, so that the risk of injury is reduced.

Im Bereich der doppelten Umkantung ist in Ausgestaltung in einem Biegebereich eine Perforation vorgesehen. Durch Perforieren des Türblatts bzw. des Blechs des Türblatts in Biegebereichen, kann das Türblatt an diesen Stellen einfach manuell umgebogen werden. Die Perforation bzw. die Perforationen zeigen die genauen Positionen an, an denen das Material des Türblatts umzubiegen ist. Üblicherweise werden die Perforationen durch Stanzen eingebracht.In the area of the double folded over, a perforation is provided in an embodiment in a bending area. By perforating the door leaf or the sheet of the door leaf in bending areas, the door leaf can be easily manually bent at these locations. The perforation or perforations indicate the exact positions at which the material of the door leaf is to be bent. Usually, the perforations are introduced by punching.

Es kann zusätzlich im Bereich der doppelten Umkantung ein Befestigungselement, wie bspw. eine Schraube oder eine Verklipsung, vorgesehen sein. Hierdurch wird verhindert, dass die beiden Material- bzw. Blechstücke, die im Bereich der Umkantung übereinanderliegen, freigleitend sind, so dass das Widerstandsmoment erheblich erhöht wird. Alternativ kann das Material auch vernietet werden. Alternativ oder ergänzend zu der Schraube kann eine Nietverbindung, Schweißung und/oder ein sonstiges geeignetes Verbindungselement vorgesehen sein.It can additionally be provided in the region of the double fold a fastener, such as. A screw or Verklipsung. This prevents that the two pieces of material or sheet metal, which lie one above the other in the region of the fold, are free-conducting, so that the moment of resistance is increased considerably. Alternatively, the material can also be riveted. Alternatively or in addition to the screw, a rivet connection, welding and / or another suitable connection element may be provided.

Außerdem kann im oberen Bereich des Aufzugstürblatt zur Befestigung des Türblatts mindestens ein Loch und im unteren Bereich zum Anbringen von mindestens einer Türblattführung eine doppelte Umkantung vorgesehen sein. Zur Befestigung des Türblatts wird bspw. ein Laufwagen eingesetzt, an dem das Türblatt befestigt werden kann.In addition, at least one hole can be provided in the upper area of the elevator door leaf for fastening the door leaf, and a double folded edge in the lower area for attaching at least one door leaf guide. For fastening the door leaf, for example, a carriage is used, on which the door leaf can be attached.

Es ist weiterhin ein Aufzugstürblatt mit einer Anzahl von Umkantungen vorgesehen, bei dem im Bereich mindestens einer der Umkantungen in einem Biegebereich eine Perforation vorgesehen ist. Diese Perforation, die bspw. durch Stanzen eingebracht ist, ermöglicht ein einfaches, positionsgenaues Umbiegen ohne großen Kraftaufwand, so dass das Umbiegen auch manuell ohne Maschineneinsatz durchgeführt werden kann.Furthermore, an elevator door leaf with a number of folds is provided, in which a perforation is provided in the area of at least one of the folded edges in a bending area. This perforation, which is introduced, for example, by punching, allows a simple, positionally accurate bending without much effort, so that the bending can also be performed manually without machine use.

Die erfindungsgemäße Aufzugstür umfasst mindestens zwei Aufzugstürblätter der vorstehend beschriebenen Art. Dabei können die Türblätter zum Öffnen und Schließen der Tür gleichgerichtet oder gegengerichtet bewegt werden.The elevator door according to the invention comprises at least two elevator door leaves of the type described above. In this case, the door leaves for opening and closing the door can be rectified or moved in the opposite direction.

In Ausgestaltung ist bei der Aufzugstür zumindest im geschlossenen Zustand zwischen zwei der Aufzugstürblätter ein Labyrinth gebildet. Dieses Labyrinth ist regelmäßig bei Feuerwiderstandstüren vorgesehen und wird bspw. dadurch erreicht, dass die Hinterkante des Türblatts so ausgeführt ist, dass es in geschlossenem Zustand mit einer Zarge oder einem zweiten Türblatt gebildet wird.In an embodiment, in the elevator door, at least in the closed state, between two of the elevator door leaves Labyrinth formed. This labyrinth is regularly provided in fire resistance doors and is, for example, achieved in that the trailing edge of the door leaf is designed so that it is formed in the closed state with a frame or a second door leaf.

Das erfindungsgemäße Verfahren dient zum Herstellen eines beschriebenen Aufzugstürblatts, wobei zur Vornahme einer Umkantung die Schale bzw. das Material des Türblatts im Bereich einer Perforation gebogen wird.The inventive method is used to produce a described elevator door leaf, wherein the shell or the material of the door leaf is bent in the region of a perforation to make a folded over.

Weitere Vorteile und Ausgestaltungen der Erfindung ergeben sich aus der Beschreibung und der beiliegenden Zeichnung.Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.

In Figur 1 ist ein Türblatt gemäß dem Stand der Technik dargestellt, das insgesamt mit der Bezugsziffer 10 bezeichnet ist. Dieses Türblatt 10, das einschalig ausgebildet ist, ist aus einem flächigen Material gefertigt und umfasst eine als C gekantete Vorderkante 12 und eine als C gekantete Hinterkante 14. Weiterhin zeigt die Darstellung eine Zarge 16, die mit dem Türblatt 10 zusammenwirkt. Anstelle der Zarge 16 kann auch ein zweites Türblatt vorgesehen sein.In FIG. 1 a door leaf according to the prior art is shown, which is generally designated by the reference numeral 10. This door leaf 10, which is formed as a single shell, is made of a flat material and comprises a front edge 12 folded as C and a trailing edge 14 folded as a C, and the illustration also shows a frame 16 which interacts with the door leaf 10. Instead of the frame 16 may also be provided a second door leaf.

In der Darstellung ist zu erkennen, wie sich zwischen dem Türblatt 10 im Bereich der Hinterkante 14 und der Zarge 16 ein Labyrinth 18 ausbildet, das aus Sicherheitsgründen vorgesehen ist.In the illustration it can be seen how a labyrinth 18 forms between the door leaf 10 in the region of the trailing edge 14 and the frame 16, which is provided for safety reasons.

Da bei einer solchen Anordnung der Kanten bzw. Kantungen, nämlich der Vorderkante 12 und der Hinterkante 14, die Stabilität des Türblatts 10 verhältnismäßig gering ist, gibt es Variationen, die die Stabilität und Steifigkeit des Türblatts 10 erhöhen.Since in such an arrangement of the edges or edging, namely the leading edge 12 and the trailing edge 14, the stability of the door leaf 10 is relatively low, there There are variations that increase the stability and rigidity of the door leaf 10.

Figur 2 zeigt ein weiteres bekanntes Türblatt 20, das eine erhöhte Steifigkeit aufweist. Dieses Türblatt 20 umfasst eine als C gekantete Vorderkante 22 und eine als C gekantete Hinterkante 24. Die Darstellung zeigt außerdem wiederum eine Zarge 26, die mit dem Türblatt 20 zusammenwirkt, so dass sich im geschlossenen Zustand ein Labyrinth 28 ausbildet. Zusätzlich ist im Bereich der Hinterkante 24 eine Aussteifung 30 vorgesehen, die durch Umkantung des Materials bzw. des Blechs des Türblatts 20 im Bereich der Hinterkante 24 eingebracht wird. Diese Aussteifung 30 verleiht dem Türblatt 20 zwar eine erhöhte Festigkeit, die jedoch regelmäßig nicht ausreichend ist. FIG. 2 shows another known door leaf 20, which has an increased rigidity. This door leaf 20 comprises a front edge 22 folded as C and a trailing edge 24 folded as C. The illustration also shows in turn a frame 26 which cooperates with the door leaf 20 so that a labyrinth 28 is formed in the closed state. In addition, a stiffener 30 is provided in the region of the rear edge 24, which is introduced by bending over the material or the sheet of the door leaf 20 in the region of the trailing edge 24. Although this stiffener 30 gives the door leaf 20 increased strength, which is regularly not sufficient.

In Figur 3 ist ein weiteres Türblatt 40 gemäß dem Stand der Technik dargestellt, das wiederum eine als C gekantete Vorderkante 42 aufweist. In diesem Fall ist jedoch das Türblatt 40 im Bereich der Hinterkante 44 nur einfach umgebogen. Weiterhin ist wiederum eine Zarge 46 und ein zwischen der Zarge 46 und dem Türblatt 40 im Bereich der Hinterkante 44 gebildetes Labyrinth 48 zu erkennen.In FIG. 3 a further door leaf 40 according to the prior art is shown, which in turn has a canted edge C edge 42. In this case, however, the door leaf 40 is only bent over in the region of the trailing edge 44. Furthermore, in turn, a frame 46 and between the frame 46 and the door panel 40 in the region of the trailing edge 44 formed labyrinth 48 can be seen.

Zur Erhöhung der Stabilität ist bei dem dargestellten Türblatt 40 ein zusätzlicher Blechwinkel 50 an der Hinterkante 44 des Türblatts 40 angebracht. Mit diesem zusätzlichen Blechwinkel 50 kann eine ausreichende Festigkeit erreicht werden. Somit ist es selbst bei Aufzugstüren mit großer Breite aus Stabilitätsgründen nicht mehr erforderlich, zusätzliche Aussteifungsprofile anzubringen.To increase the stability of the illustrated door leaf 40, an additional sheet metal bracket 50 is attached to the trailing edge 44 of the door panel 40. With this additional sheet metal angle 50 sufficient strength can be achieved. Thus, it is no longer necessary even with elevator doors with large width for stability reasons, to install additional stiffening profiles.

Nachteilig bei dem Türblatt 40 gemäß dem Stand der Technik ist jedoch, dass ein zusätzliches Teil, nämlich der Blechwinkel 50, erforderlich ist. Dies ist bspw. bei der Fertigung von Nachteil, da bei dieser der Blechwinkel 50 zu dem Türblatt 40 positioniert werden muss.A disadvantage of the door leaf 40 according to the prior art, however, is that an additional part, namely the sheet metal angle 50, is required. This is, for example, in the production disadvantageous because in this the metal bracket 50 must be positioned to the door panel 40.

In Figur 4 ist eine mögliche Ausführungsform des erfindungsgemäßen Türblatts, insgesamt mit der Bezugsziffer 60 bezeichnet, in schematischer Darstellung wiedergegeben. Auch dieses Türblatt 60 umfasst eine als C geformte Vorderkante 62. Die Hinterkante 64, die ebenfalls C-förmig ausgebildet ist, verleiht dem Türblatt 60 eine ausreichende Stabilität. Wiederum ist eine Zarge 66 dargestellt, die mit der Hinterkante 64 des Türblatts 60 ein Labyrinth 68 definiert.In FIG. 4 is a possible embodiment of the door panel according to the invention, generally designated by the reference numeral 60, shown in a schematic representation. This door leaf 60 also includes a front edge 62 shaped as C. The trailing edge 64, which is likewise C-shaped, gives the door leaf 60 sufficient stability. Again, a frame 66 is shown which defines a labyrinth 68 with the trailing edge 64 of the door panel 60.

Dabei ist die Hinterkante 64 durch doppelte Umkantung des Materials bzw. des Blechs des Türblatts 60 hergestellt. Auf diese Weise ist die Hinterkante mit einem oberen Schenkel 70 und einem unteren Schenkel 72 ausgebildet. Zu beachten ist, dass der untere Schenkel 72 durch die doppelte Umkantung, d.h. durch eine Umkantung um 180°, eine doppelte Stärke aufweist, da in diesem Bereich das verwendete Blech doppelt vorliegt. D.h. in diesem Bereich liegt eine Verstärkung bzw. Aussteifung vor, da das Material des Türblatts 60 doppelt gegeben ist. Durch das doppelte Umkanten liegen somit zwei Schichten bzw. Lagen des eingesetzten Materials bzw. Blechs aufeinander.In this case, the trailing edge 64 is produced by double edging of the material or the sheet of the door leaf 60. In this way, the trailing edge is formed with an upper leg 70 and a lower leg 72. It should be noted that the lower leg 72 is formed by the double fold, i. by a Umbantung by 180 °, a double thickness, since in this area the sheet used is present twice. That in this area, there is a reinforcement or stiffening, since the material of the door panel 60 is given twice. As a result of the double edge, there are two layers or layers of the material or sheet used.

Das dargestellte Türblatt 60 verfügt über eine hohe Festigkeit und kann aus einem einzigen Stück Blech gefertigt bzw. gekantet werden. Insbesondere die "doppelte" C-Kantung erhöht hierbei die Steifigkeit. Dabei ist zu beachten, dass keine zusätzlichen Befestigungselemente oder Blechteile notwendig sind. "Doppelte" C-Kantung bedeutet, dass die C-förmige Hinterkante durch zwei C's, einem oberen C und einem unteren C, gebildet ist.The illustrated door leaf 60 has a high strength and can be made or folded from a single piece of sheet metal. In particular, the "double" C-edge increases the stiffness. It should be noted that no additional fasteners or sheet metal parts are necessary. "Double" C-edge means that the C-shaped trailing edge is formed by two C's, an upper C and a lower C.

Im Bereich der Biegekante 74 an dem unteren Schenkel 72 kann das Material des Türblatts 60 eine Perforation, die in dieser Darstellung nicht zu erkennen ist, aufweisen. Auf diese Weise kann das Umkanten bzw. der Biegevorgang einfach und auch manuell durchgeführt werden. Der Einsatz einer Maschine ist nicht erforderlich. Die Position der Biegekante 74 ist exakt vorzugeben.In the region of the bending edge 74 on the lower leg 72, the material of the door leaf 60 may have a perforation, which can not be seen in this illustration. In this way, the edge or the bending process can be carried out easily and manually. The use of a machine is not required. The position of the bending edge 74 is to specify exactly.

In Figur 5 ist eine weitere Ausführungsform des erfindungsgemäßen Türblatts, insgesamt mit der Bezugsziffer 80 versehen, dargestellt. Dieses Türblatt 80, das aus einem flächigen Blechmaterial hergestellt ist, umfasst eine C-förmige Vorderkante 82 und eine doppelt C-förmige Hinterkante 84 mit einem oberen Schenkel 86 und einem unteren Schenkel 88. Die Darstellung zeigt, dass der untere Schenkel 90 der Vorderkante 82 eine Umkantung 92 und der obere Schenkel 86 der Hinterkante 84 ebenfalls eine Umkantung 94 aufweist. Diese Umkantungen 92 und 94 dienen als Kantenschutz und sind somit aus Sicherheitsgründen vorgesehen. Grundsätzlich wird darauf geachtet, dass sämtliche Kanten, bspw. durch geeignete Verkleidungen, außerhalb des Sichtbereichs liegen.In FIG. 5 is a further embodiment of the door panel according to the invention, generally designated by the reference numeral 80, shown. This door leaf 80, which is made of a sheet-metal sheet material, comprises a C-shaped front edge 82 and a double C-shaped trailing edge 84 having an upper leg 86 and a lower leg 88. The illustration shows that the lower leg 90 of the front edge 82nd a folded edge 92 and the upper leg 86 of the trailing edge 84 also has a folded edge 94. This Umkantungen 92 and 94 serve as edge protection and are therefore provided for security reasons. In principle, care is taken to ensure that all edges, for example by means of suitable cladding, are outside the field of view.

Figuren 6 und 7 verdeutlichen die Herstellung eines Türblatts 100 mit einer Vorderkante 102 und einer Hinterkante 104. Durch Umbiegen des Materials des Türblatts um eine Biegekante 106 in Richtung eines Pfeils 108 um etwa 180° wird das doppelte C der Hinterkante 104 mit dem doppelten unteren Schenkel 110 erreicht. FIGS. 6 and 7 illustrate the production of a door leaf 100 having a front edge 102 and a trailing edge 104. By bending the material of the door leaf about a bending edge 106 in the direction of an arrow 108 by about 180 °, the double C of the trailing edge 104 is achieved with the double lower leg 110.

Zur Vereinfachung des Umbiegens weist das Türblatt 100 im Bereich der Biegekante 106 eine Perforation auf. Derartige Perforationen können auch an anderen, für ein Umkanten bzw. Umbiegen vorgesehenen Stellen gegeben sein.To simplify the bending, the door leaf 100 has a perforation in the region of the bending edge 106. Such perforations may also be provided at other locations provided for edge-bending.

In Figur 8 ist ein weiteres erfindungsgemäßes Türblatt 120 wiedergegeben, das eine C-förmige Vorderkante 122 und eine doppelt C-förmige Hinterkante 124 mit einem oberen Schenkel 126 und einem unteren Schenkel 128 umfasst. Zusätzlich ist ein Befestigungselement 130, in diesem Fall eine Schraube 130, vorgesehen. Diese Schraube 130 fixiert die beiden aufeinanderliegenden Schichten bzw. Lagen des Materials des Türblatts 120 zueinander, so dass diese nicht mehr freigleitend, d.h. zueinander verschiebbar, sind. Auf diese Weise wird ein erhöhtes Widerstandsmoment erreicht, das in etwa dem Widerstandsmoment eines Blechs doppelter Wandstärke entspricht.In FIG. 8 another door panel 120 according to the invention is shown comprising a C-shaped leading edge 122 and a double C-shaped trailing edge 124 having an upper leg 126 and a lower leg 128. In addition, a fastening element 130, in this case a screw 130, is provided. This screw 130 fixes the two superimposed layers or layers of the material of the door leaf 120 to each other, so that they are no longer free-sliding, ie, mutually displaceable, are. In this way, an increased resistance moment is achieved, which corresponds approximately to the moment of resistance of a sheet of double wall thickness.

Figur 9 zeigt auf der linken Seite ein weiteres erfindungsgemäßes Türblatt 140 mit einer Vorderkante 142 und einer Hinterkante 144, wobei der durch einen Kreis 146 umspannte Ausschnitt, nämlich die Hinterkante 144, auf der rechten Seite der Darstellung vergrößert wiedergegeben ist. FIG. 9 shows on the left side another door panel 140 according to the invention with a front edge 142 and a trailing edge 144, wherein the section enclosed by a circle 146, namely the trailing edge 144, is reproduced enlarged on the right side of the illustration.

In der vergrößerten Darstellung der Hinterkante 144 sind der obere Schenkel 148 und der untere Schenkel 150 zu erkennen. Im Bereich des unteren Schenkels 150 liegt das Material doppelt vor, d.h. es liegen zwei Schichten des Materials des Türblatts 140 auf- bzw. nebeneinander. Weiterhin ist ein an das Material des Türblatts 140 angebrachter oder auch angeformter Steg 152 vorgesehen, der in eine im Material des Türblatts 140 an entsprechender Stelle eingebrachte Ausnehmung 154 zur Bereitstellung einer Verklipsung 156 als Befestigungselement eingreift.In the enlarged view of the trailing edge 144, the upper leg 148 and the lower leg 150 can be seen. In the area of the lower leg 150, the material is in duplicate, i. There are two layers of the material of the door leaf 140 up or next to each other. Furthermore, an attached to the material of the door leaf 140 or also integrally molded web 152 is provided, which engages in an introduced in the material of the door leaf 140 at a corresponding point recess 154 for providing Verklipsung 156 as a fastener.

Bei der Herstellung des Türblatts 140 greift somit der Steg 152 nach Umbiegen des Materials des Türblatts 140 um die Biegekante 158 in die Ausnehmung 154 und gewährleistet auf diese Weise, dass die beiden Lagen des Materials im Bereich des unteren Schenkels 150 nicht mehr freigleitend sind. Folglich wird ein erhöhtes Widerstandsmoment erreicht.In the production of the door leaf 140 thus engages the web 152 after bending the material of the door leaf 140 about the bending edge 158 in the recess 154 and ensures in this way that the two layers of material in the area of the lower leg 150 are no longer free-conducting. Consequently, an increased resistance moment is achieved.
