Abstract

A building has an elevator shaft and elevator cars to which access is provided by two sets of parallel sliding doors moving on rollers (20, 21, 26) that engage with overhead rails (10). The rail has a box section (11) containing track (12, 22) with an exposed surface (13, 14, 23, 24). The box section has one length (11a) in which the running surface is exposed towards the elevator shaft, but is screened from a point outside the shaft. The track (12, 22) and box section (11) are formed from a single piece of bent sheet metal.

Description

Die vorliegende Erfindung betrifft einen Türkämpfer für eine Aufzugtür.The present invention relates to a door striker for an elevator door.

Horizontal verschiebbare bzw. verfahrbare Schiebetüren sind bei Aufzuganlagen zum Abschluß der Fahrkörbe und der Schachtöffnungen bekannt. Die Schiebetüren werden üblicherweise an ihrer Oberkante mittels Laufrollen längs eines waagrecht über der Türöffnung verlaufenden Stützbalkens der entsprechenden Türeinrichtung geführt, wobei ein solcher Stützbalken auch als Türkämpfer bezeichnet wird.Horizontally displaceable or movable sliding doors are known in elevator systems for the completion of the cars and shaft openings. The sliding doors are usually guided at their upper edge by means of rollers along a horizontally extending above the door opening support beam of the corresponding door device, wherein such a support bar is also referred to as door striker.

Aus der EP 0 709 337 B1 ist ein oben liegender Stützbalken für eine Aufzugtür bekannt, der mit Rollbahnen für die Laufrollen von Türblättern einer Aufzugschiebetür versehen ist. Hierbei ist der Stützbalken in der Weise ausgebildet, daß die Rollbahnen einstückig mit dem Stützbalken geformt sind. Jedoch unterliegt der hier gezeigte Stützbalken dem Nachteil, daß zumindest der untere Bereich des Stützbalkens mit den daran angeordneten Rollbahnen keine Abdeckung gegenüber den Türbenutzern aufweist, so daß diese ungehindert in die Türführungen greifen und sich auch verletzen können. Um diese Gefahr zu vermeiden, wäre eine zusätzliche Konstruktion zum Abdecken der entsprechenden Rollbahnen erforderlich.EP 0 709 337 B1 discloses an overhead support beam for an elevator door, which is provided with roller tracks for the rollers of door leaves of an elevator sliding door. Here, the support bar is formed in such a way that the roller tracks are integrally formed with the support beam. However, the support beam shown here is subject to the disadvantage that at least the lower portion of the support beam with the runways thereon has no cover against the door users, so that they can freely engage in the door guides and injure themselves. To avoid this danger, an additional construction to cover the corresponding runways would be required.

Aus der EP 0 458 658 A1 ist ein Türkämpfer für eine Fahrkorbschiebetür bekannt, der für zwei- oder mehrblättriqe Schiebetüren eingesetzt werden kann. Der Türkämpfer besteht aus einem aus Aluminium oder Kunststoff hergestellten Profil in L-Form mit integrierten Führungsbahnen, die für die Lauf- und Gegenrollen der jeweiligen Türblätter vorgesehen sind. Bei der Herstellung aus Aluminium wird das Profil des Türkämpfers z.B. durch Ziehen erzielt, wodurch sich im gleichen Fertigungsschritt diverse Nuten zur Befestigung des Profils an dem Fahrkorb herstellen lassen. Diese Herstellungsweise ist jedoch wegen der sehr aufwendigen und kostspieligen Matrize, die für das Ziehen erforderlich ist, sehr teuer. Die vorgegebene Form der Matrize läßt ferner keine flexible Fertigung des Türkämpfers zu. Letztlich bringt ein aus Aluminium gefertigter Türkämpfer aufgrund des niedrigen Materialschmelzpunktes Probleme bei der Brandsicherheit mit sich.From EP 0458658 A1, a door striker for a car sliding door is known, which is suitable for two- or mehrblättriqe Sliding doors can be used. The door hinge is made of an aluminum or plastic profile in L-shape with integrated guideways, which are provided for the running and counter rollers of the respective door leaves. In the production of aluminum, the profile of the door striker is achieved for example by pulling, which can be produced in the same manufacturing step various grooves for attaching the profile to the car. However, this method of manufacture is very expensive because of the very expensive and expensive die required for drawing. The predetermined shape of the die also does not allow for flexible production of the door fighter. Ultimately brings a made of aluminum door hinge due to the low melting point material problems in fire safety.

Ein zum internen Stand der Technik der Patentanmelderin gehörender herkömmlicher Türkämpfer ist in Figur 8 in einer seitlichen Querschnittsansicht gezeigt. Der Türkämpfer 100 besteht im wesentlichen aus einem aus einem Blech geformten Kastenelement 101 und aus einem Führungselement 102, an dem eine obere Laufschiene 103 und eine untere Laufschiene 104 für die Laufrollen von entsprechenden Schiebetüren vorgesehen sind. Bei der Fertigung eines solchen bekannten Türkämpfers werden das Kastenelement und das Führungselement jeweils als Einzelteil hergestellt, und im Anschluß daran in einem zweiten Fertigungsschritt in geeigneter Weise, z.B. durch Schweißen, miteinander verbunden. Entsprechend ist die Herstellung dieses Türkämpfers im Hinblick auf ein exaktes Positionieren von Kastenelement und Führungselement vor dem Verschweißen, auf eine hohe Güte der Schweißverbindung und dergleichen relativ aufwendig und teuer. Im übrigen kann sich beim Verschweißen der Bauteile durch die dabei eingebrachte Wärme ein Verzug einstellen, mit entsprechend bekannten Nachteilen.A conventional door steamer inherent in the prior art of the Applicant is shown in Figure 8 in a side cross-sectional view. The door striker 100 consists essentially of a formed from a sheet box member 101 and a guide member 102, on which an upper rail 103 and a lower rail 104 are provided for the rollers of corresponding sliding doors. In the manufacture of such a known door fighter, the box element and the guide element are each manufactured as a single part, and subsequently connected in a second manufacturing step in a suitable manner, for example by welding. Accordingly, the manufacture of this door damper with respect to an exact positioning of box element and guide element before welding, to a high quality of the welded joint and the like is relatively complicated and expensive. Incidentally, when welding the components through the case introduced heat set a delay, with corresponding known disadvantages.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, einen Türkämpfer zu schaffen, der kostengünstig und flexibel herstellbar ist und eine ausgezeichnete Brandsicherheit und Betriebssicherheit bei der Betätigung einer Türe gewährleistet und auch einen sichtbaren oberen Abschluß der Türöffnung bildet.Based on this, the present invention seeks to provide a door hinge, which is inexpensive and flexible to produce and ensures excellent fire safety and reliability in the operation of a door and also forms a visible upper end of the door opening.

Zur Lösung dieser Aufgabe wird ein Türkämpfer mit den Merkmalen des Anspruches 1 vorgeschlagen. Bei dem erfindungsgemäßen Türkämpfer weist das Kastenteil einen Abschnitt auf, der die Lauffläche gegenüber dem Türbenutzer abschirmt. Dabei ist sichergestellt, daß der Türbenutzer nicht in den Bereich der Lauffläche hineingreifen kann, in dem eine Laufrolle eines entsprechenden Türblattes auf der Lauffläche abrollt. Der genannte Abschnitt des Kastenteils kann im wesentlichen vertikal ausgerichtet sein. Ferner kann das Kastenteil einen unteren Bereich aufweisen, der einen dem Benutzer zugewandten oberen Abschluß einer Türöffnung bildet. Das Kastenteil und der zumindest eine Laufflächenträger sowie die zumindest eine Lauffläche sind aus einem einzigen Blech gebogen, wodurch sich der Türkämpfer in einem einzigen Fertigungsschritt profilieren läßt. Zusätzliche Fertigungsschritte zum separaten Verbinden des Kastenteils mit dem mindestens einen Laufflächenträger sind somit nicht erforderlich. Eine solche Herstellung ist beispielsweise durch Profilieren mittels einer Profiliermaschine realisierbar, z.B. durch Rollieren als Meterware oder durch Kanten von Blechplatten mit einer Kantmaschine. Hierbei ist in vorteilhafter Weise eine hohe Flexibilität der Fertigung gewährleistet, da keine aufwendige und in ihren Abmessungen im voraus festgelegte Matrize zum Ziehen oder dergleichen vorgehalten zu werden braucht. Im Ergebnis gewährleistet der erfindungsgemäße Türkämpfer eine einfache und wirtschaftliche Herstellung, bei der außerdem eine hohe Flexibilität möglich ist.To solve this problem, a door striker with the features of claim 1 is proposed. In the case of the door striker according to the invention, the box part has a section which shields the running surface from the door user. It is ensured that the door user can not reach into the region of the tread in which rolls a roller of a corresponding door leaf on the tread. The said portion of the box part may be oriented substantially vertically. Furthermore, the box part may have a lower portion which forms a user facing upper end of a door opening. The box part and the at least one tread carrier and the at least one tread are bent from a single sheet, which can be profiled in a single manufacturing step of the door warmer. Additional manufacturing steps for separately connecting the box part with the at least one tread carrier are therefore not required. Such a production can be realized, for example, by profiling by means of a profiling machine, for example by rolling as a piece or by edges of sheet metal plates with an edging machine. In this case, a high flexibility of production is ensured in an advantageous manner, since no consuming and in their dimensions set in advance template for pulling or the like needs to be kept. As a result, the door hinge according to the invention ensures a simple and economical production, in which also a high flexibility is possible.

Der Laufflächenträger verläuft in Längsrichtung des Türkämpfers und erstreckt sich von dem im wesentlichen vertikalen Abschnitt in Richtung des Schachtes, wobei an diesem Laufflächenträger die zumindest eine Lauffläche ausgebildet ist. Dadurch ist eine konstruktiv sehr einfache und wirksame Abschirmung der Lauffläche gegenüber dem Türbenutzer sichergestellt. Ferner kann die Lauffläche hierbei in Form eines nach oben weisenden 180°-Bogens ausgebildet sein. Dies ist in doppelter Hinsicht von Vorteil, da neben einer einfachen Fertigung eines solchen Profils der Lauffläche eine in Anpassung an den 180°-Bogen entsprechend konkav profilierte Laufrolle eines Türblattes, die von oben auf die Lauffläche aufgesetzt ist, ohne ein Entgleisen betriebssicher geführt wird.The tread carrier extends in the longitudinal direction of the door fighter and extends from the substantially vertical portion in the direction of the shaft, wherein at least one tread is formed on this tread carrier. This ensures a structurally very simple and effective shielding of the tread against the door user. Further, the tread may be formed in the form of an upward-pointing 180 ° arc. This is advantageous in two respects, since in addition to a simple production of such a profile of the tread a matching in accordance with the 180 ° arc corresponding concave profiled roller of a door leaf, which is placed from above on the tread, is reliably guided without derailment.

In weiterer vorteilhafter Ausgestaltung der Erfindung ist an dem Laufflächenträger eine zweite Lauffläche ausgebildet, die in Form eines nach unten weisenden 180°-Bogens ausgebildet ist. Fertigungstechnisch von Vorteil ist hierbei, wenn die erste Lauffläche und die zweite Lauffläche an einem freien Ende des genannten Laufflächenträgers entgegengesetzt zueinander so angeordnet sind, daß sie sich vertikal übereinander befinden, wobei die jeweiligen 180°-Bögen auf einer Seite miteinander verbunden sind. Die zweite Lauffläche dient hierbei als Gegenführung für eine weitere Laufrolle des entsprechenden Türblattes, die von unten an der zweiten Lauffläche anliegt und an dieser abrollt.In a further advantageous embodiment of the invention, a second running surface is formed on the tread carrier, which is in the form of a downwardly pointing 180 ° arc. In terms of manufacturing technology, it is advantageous here if the first running surface and the second running surface are arranged opposite one another at a free end of said tread carrier in such a way that they are located vertically one above the other, wherein the respective 180 ° bends are connected to one another on one side. The second tread serves in this case as a counter-guide for a further roller of the corresponding door leaf, which abuts from below on the second tread and rolls on this.

Ein versehentliches Abheben der von oben auf die Lauffläche aufgesetzten Laufrolle und ein dadurch bewirktes mögliches Entgleisen des Türblattes läßt sich hiermit wirkungsvoll unterbinden.Accidental lifting of the mounted on top of the tread caster and thereby caused possible derailment of the door leaf can be hereby effectively prevented.

In vorteilhafter Weiterbildung der Erfindung besteht der erste Laufflächenträger im wesentlichen aus zwei aufeinander liegenden Blechabschnitten, die durch einen vom Kastenteil wegführenden und einen zurückführenden Blechabschnitt gebildet werden. Diese Blechabschnitte sind nachfolgend als oberer und unterer erster Laufflächenträgerbereich bezeichnet. Die hierbei vorhandene doppelte Wandstärke im Vergleich zu einem einfachen Blech gewährleistet vorteilhaft eine große Stabilität des Türkämpfers und insbesondere des Laufflächenträgers in diesem Bereich, wodurch das Eigengewicht eines jeweiligen auf der Lauffläche aufliegenden Türblattes gut aufgenommen werden kann. Die zwei aufeinander liegenden Laufflächenträgerbereiche können noch zusätzlich direkt durch eine Längsschweißnaht oder dergleichen an der Außenseite des im wesentlichen vertikalen Abschnitts verbunden sein. Alternativ hierzu können die Laufflächenträgerbereiche auch in ihrem horizontalen Bereich miteinander verschweißt, z.B. durch Punktschweißen, oder verschraubt sein.In an advantageous embodiment of the invention, the first tread carrier consists essentially of two superimposed sheet metal sections, which are formed by a leading away from the box part and a recirculating sheet metal section. These sheet sections are hereinafter referred to as upper and lower first tread carrier area. The case existing double wall thickness compared to a simple sheet advantageously ensures a high stability of the door striker and in particular of the tread carrier in this area, whereby the weight of a respective resting on the tread door leaf can be well received. In addition, the two superimposed tread support regions may be directly connected by a longitudinal weld or the like on the outside of the substantially vertical portion. Alternatively, the tread carrier regions may be welded together in their horizontal region, e.g. by spot welding, or bolted.

In weiterer vorteilhafter Ausgestaltung der Erfindung kann der untere Bereich des Kastenteils einen zweiten Laufflächenträger aufweisen, der in Längsrichtung des Türkämpfers verläuft und sich vom Kastenteil weg in Schachtrichtung erstreckt, wobei an dem zweiten Laufflächenträger eine dritte Lauffläche ausgebildet ist. In gleicher Weise wie die erste Lauffläche kann die dritte Lauffläche hierbei in Form eines nach oben weisenden 180°-Bogens ausgebildet sein, was, wie erläutert, in fertigungstechnischer Hinsicht von Vorteil ist. Eine solche dritte Lauffläche ist hierbei horizontal zu der ersten Lauffläche versetzt und dient als Laufschiene für ein weiteres Türblatt, so daß der erfindungsgemäße Türkämpfer insgesamt eine Führung von mindestens zwei sich nebeneinander bewegenden Türblättern ermöglicht. Im Falle einer Aufzugtür sind dies beispielsweise ein langsam fahrendes Türblatt und ein schnell fahrendes Türblatt. Zur Erzielung einer hohen Integration des erfindungsgemäßen Türkämpfers kann die dritte Lauffläche an einem freien Ende des zweiten Laufflächenträgers ausgebildet sein.In a further advantageous embodiment of the invention, the lower portion of the box part may have a second tread carrier extending in the longitudinal direction of the door fighter and extending away from the box part in the chute direction, wherein on the second tread carrier a third tread is formed. In the same way as the first running surface, the third running surface may in this case be in the form of an upward-pointing 180 ° bend, which, like explained, is advantageous in terms of manufacturing technology. Such a third running surface is in this case offset horizontally from the first running surface and serves as a running rail for a further door leaf, so that the door striker according to the invention as a whole enables a guidance of at least two door leaves moving side by side. In the case of an elevator door, these are, for example, a slow-moving door leaf and a fast-moving door leaf. To achieve a high degree of integration of the door damper according to the invention, the third running surface may be formed at a free end of the second tread carrier.

Gleichzeitig dient die Unterseite des zweiten Laufflächenträgers als sichtbarer Abschluß der nutzbaren Türöffnung.At the same time the underside of the second tread carrier serves as a visible closure of the usable door opening.

Ein nachteiliges Abheben einer auf die dritte Lauffläche aufgesetzten Laufrolle von dieser Lauffläche läßt sich vorteilhaft dadurch vermeiden, daß in weiterer vorteilhafter Ausgestaltung der Erfindung der erste Laufflächenträger eine vierte Lauffläche aufweist, die der dritten Lauffläche gegenüberliegend und mit dieser vertikal ausgerichtet ist. An dem Türblatt, das auf der dritten Lauffläche geführt wird, ist eine weitere Laufrolle vorgesehen, die von unten an der vierten Lauffläche anliegt und an dieser abrollt. Auch hierbei kann die vierte Lauffläche vorteilhaft in Form eines nach unten weisenden 180°-Bogens ausgebildet sein, an den die Profilierung der daran anliegenden Laufrolle entsprechend angepasst ist. Statt einer Rolle an der als Gegenführung verwendeten vierten Lauffläche kann auch eine Gleitführung verwendet werden.A disadvantageous lifting of an attached to the third tread roller of this tread can be advantageously avoided in that in a further advantageous embodiment of the invention, the first tread carrier has a fourth tread, which is the third tread opposite and aligned with this vertically. On the door leaf, which is guided on the third running surface, a further roller is provided, which abuts from below on the fourth tread and rolls on this. Again, the fourth tread may be advantageously formed in the form of a downward-pointing 180 ° arc to which the profiling of the adjacent thereto roller is adjusted accordingly. Instead of a roller on the fourth running surface used as a counter-guide, a sliding guide can also be used.

In vorteilhafter Weiterbildung der Erfindung weist der Türkämpfer an seiner Oberseite einen horizontalen Abdeckbereich gegen von oben herabfallendes Material, Schmutz oder Flüssigkeit auf, an dessen freiem Ende ein nach unten weisendes Abdeckblech zur offenen Schachtseite hin angebracht werden kann.In an advantageous embodiment of the invention, the door hinge on its upper side a horizontal covering area against falling from above material, dirt or liquid on the free end of a downwardly facing cover plate can be attached to the open shaft side.

Der erfindungsgemäße Türkämpfer läßt sich vorteilhaft für jegliche Aufzugtürbetätigungseinrichtungen verwenden, bei denen horizontal verschiebbare Türblätter bzw. Schiebetüren vorgesehen sind.The door striker according to the invention can be used advantageously for any elevator door actuation devices in which horizontally displaceable door leaves or sliding doors are provided.

Zusätzlich zu den bisher genannten Laufflächen können für den erfindungsgemäßen Türkämpfer noch weitere Laufflächen für weitere Türblätter vorgesehen sein, welche Laufflächen auf die gleiche, voranstehend erläuterte Art hergestellt werden können. Beispielsweise lässt sich dies realisieren, indem eine oder mehrere Faltungen mit entsprechender Ausformung an den gewünschten Stellen des Türkämpferquerschnitts eingefügt werden. Somit ist der erfindungsgemäße Türkämpfer nicht auf die Führung von Türblättern in nur zwei nebeneinanderliegenden Ebenen beschränkt, sondern es können nach Wunsch weitere Laufflächen angeordnet werden, die über die ganze Länge des Türkämpfers verlaufen, wobei diese Laufflächen für eine dritte Ebene, eine vierte Ebene oder auch noch weitere Ebenen dienen.In addition to the previously mentioned running surfaces, further running surfaces for further door leaves can be provided for the door warmer according to the invention, which running surfaces can be produced in the same way as explained above. For example, this can be realized by inserting one or more folds with appropriate shaping at the desired locations of the doorstep cross section. Thus, the door hinge according to the invention is not limited to the guidance of door leaves in only two adjacent planes, but it can be arranged as desired further treads that run the entire length of the door striker, these treads for a third level, a fourth level or even serve even more levels.

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.

Es versteht sich, daß die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained not only in the particular combination given, but also in other combinations or alone, without departing from the scope of the present invention.

Figur 1 zeigt einen seitlichen Querschnitt eines erfindungsgemäßen Türkämpfers 10 in einer ersten Ausführungsform. Der Türkämpfer 10 weist ein Kastenteil 11 auf, das sich in einem Hauptabschnitt auf der dem Schacht abgewandten Seite vertikal erstreckt und hierbei einen vertikalen Abschnitt 11a mit einem oberen Teil 15a und einem unteren Teil 15b bildet. Im Querschnitt weist der Türkämpfer 10 in dem Bereich, wo der obere Teil 15a und der untere Teil 15b aneinanderstoßen, einen ersten Laufflächenträger 12 auf, der sich auf der Schachtseite des Kastenteils 11, in der Figur 1 auf der rechten Seite des Kastenteils 11, vom Kastenteil 11 weg in Richtung Schacht, also in der Fig. nach rechts erstreckt. An einem freien Ende 12a auf der Schachtseite des ersten Laufflächenträgers 12 ist zumindest eine Lauffläche, nachfolgend als erste Lauffläche 13 bezeichnet, ausgebildet. Ferner ist an dem freien Ende 12a des ersten Laufflächenträgers 12 eine zweite Lauffläche 14 ausgebildet, die der ersten Lauffläche 13 vertikal entgegengesetzt ist. Dabei ist die erste Lauffläche 13 nach oben gerichtet und die zweite Lauffläche 14 zeigt nach unten. Beide Laufflächen sind jeweils als 180°-Bögen geformt und auf der Schachtseite miteinander verbunden. Die erste Lauffläche 13 und die zweite Lauffläche 14 bilden jeweils Laufschienen für entsprechende Laufrollen eines Türblattes, die auf den Laufschienen abrollen können.FIG. 1 shows a lateral cross-section of a door damper 10 according to the invention in a first embodiment. The door striker 10 has a box part 11 which extends vertically in a main section on the side facing away from the shaft and in this case forms a vertical section 11a with an upper part 15a and a lower part 15b. In cross section, the door striker 10 in the area where the upper part 15a and the lower part 15b abut each other, a first tread 12, located on the shaft side of the box part 11, in the figure 1 on the right side of the box part 11, from Box part 11 away in the direction of the shaft, that extends in the figure to the right. At a free end 12a on the shaft side of the first tread carrier 12, at least one tread, hereinafter referred to as the first tread 13, is formed. Further, at the free end 12a of the first tread carrier 12, a second tread 14 is formed which is vertically opposite to the first tread 13. In this case, the first tread 13 is directed upward and the second tread 14 points down. Both treads are each formed as a 180 ° bends and connected to each other on the shaft side. The first running surface 13 and the second running surface 14 each form rails for corresponding rollers of a door leaf, which can roll on the rails.

Der erste Laufflächenträger 12 verläuft in Längsrichtung des Türkämpfers 10. Da entsprechend die genannten beiden Laufflächen 13 und 14 ebenfalls in Längsrichtung des Türkämpfers verlaufen, ist somit eine Führungseinrichtung über die Breite des Türkämpfers vorgesehen.The first tread carrier 12 extends in the longitudinal direction of the door fighter 10. Since accordingly said two treads 13 and 14 also extend in the longitudinal direction of the door fighter, thus a guide means on the width of the door fighter is provided.

Gemäß Figur 3 ist der vertikale Abschnitt 11a des Kastenteils 11 mit dem oberen Teil 15a und dem unteren Teil 15b dem Türbenutzer zugewandt und deckt den oberen Bereich einer Wandöffnung 46 ab, in der der Türkämpfer 10 angeordnet ist. Dadurch sind die Laufflächen, bzw. die Kontaktstellen zwischen den jeweiligen Laufrollen und den Laufflächen, von dem Benutzer abgeschirmt, so daß ein verletzungsträchtiger Eingriff in die Türblattführung wirksam unterbunden ist.According to FIG. 3, the vertical portion 11a of the box part 11 with the upper part 15a and the lower part 15b faces the door user and covers the upper area of a wall opening 46 in which the door striker 10 is arranged. As a result, the running surfaces, or the contact points between the respective rollers and the running surfaces, shielded by the user, so that an injury-intensive engagement in the door leaf guide is effectively prevented.

Die genannte Wandöffnung 46 ist z.B. in einer Schacht- oder Fahrkorbwand 45 angeordnet, die in der Figur 3 oben ausschnittsweise gezeigt ist. Der Türkämpfer 10 weist am freien Ende seiner horizontalen Abdeckung 11b ferner eine Abkantung 16 auf, an der beispielsweise eine Abdeckung 40 als Abdeckung gegen den offenen Schacht aufgehängt werden kann.Said wall opening 46 is e.g. arranged in a shaft or car wall 45, which is shown in fragmentary detail in Figure 3 above. The door striker 10 has at the free end of its horizontal cover 11b also has a fold 16 on which, for example, a cover 40 can be hung as a cover against the open shaft.

Aus der Figur 1 ist ersichtlich, daß der gesamte Türkämpfer 10 aus einem einzigen gebogenen Blech hergestellt ist. Im Ergebnis sind die Laufflächen einstückig mit dem Kastenteil und dem Laufflächenträger ausgebildet, was Vorteile bei der Fertigung bietet. Die hier im Querschnitt gezeigte Formgebung des Türkämpfers 10 läßt sich durch Profilieren mittels einer Profiliermaschine oder dergleichen erzielen. Der Türkämpfer 10 kann insbesondere durch Rollieren als Meterware hergestellt werden.From the figure 1 it can be seen that the entire door striker 10 is made of a single bent sheet metal. As a result, the treads are formed integrally with the box part and the tread carrier, which offers advantages in manufacturing. The shape shown here in cross section of the door damper 10 can be achieved by profiling by means of a profiling machine or the like. The door striker 10 can be made in particular by rolling as a piece of goods.

Beim Herstellen des Türkämpfers durch Rollieren werden aus dem Blech folgende Bauteile des Türkämpfers aufeinanderfolgend ausgebildet. Zunächst wird eine obere horizontale Abdeckung 11b des Kastenteils 11 geformt, und daran anschließend der obere Teil 15a des im wesentlichen senkrechten Abschnitts 11a. Hiernach wird das Blech um ca. 90° gebogen, um den ersten Laufflächenträger 12 auszubilden, der aus dem oberen ersten Laufflächenträgerbereich 12b und aus dem unteren ersten Laufflächenträgerbereich 12c besteht. Die Verformung des Blechs geschieht dabei in der Weise, daß am freien Ende 12a des Laufflächenträgers, also zwischen den oberen und unteren ersten Laufflächenträgerbereichen, die erste Lauffläche 13 und die zweite Lauffläche 14 vorgesehen sind, wobei das Blech direkt von der ersten zur zweiten Lauffläche verläuft. Hieran anschließend wird das Blech nach dem unteren ersten Laufflächenträgerbereich wieder um 90° verformt, so daß der untere Teil 15b des im wesentlichen vertikalen Abschnitts 11a ausgebildet wird, wobei der untere Teil 15b mit dem oberen Teil 15a fluchtet. Der untere Teil 15b wird schließlich wieder um 90° gebogen, um einen zweiten Laufflächenträger 22 auszubilden, an dessen Ende eine dritte Lauffläche 23 ausgebildet ist. Eine Erläuterung von einzelnen Merkmalen des in dieser Form hergestellten Türkämpfers ist nachfolgend unter Bezugnahme auf Figur 3 gegeben.During manufacture of the door fender by rolling, the following components of the door fighter are successively formed from the metal sheet. First, an upper horizontal cover 11b of the box part 11 is formed, followed by the upper part 15a of the substantially vertical portion 11a. Thereafter, the sheet is bent by about 90 ° to form the first tread carrier 12, which consists of the upper first tread carrier portion 12b and 12c consists of the lower first tread carrier portion. The deformation of the sheet takes place in such a manner that at the free end 12a of the tread carrier, ie between the upper and lower first tread carrier areas, the first tread 13 and the second tread 14 are provided, wherein the sheet extends directly from the first to the second tread , Subsequently, after the lower first tread supporting portion, the sheet is again deformed by 90 °, so that the lower part 15b of the substantially vertical portion 11a is formed with the lower part 15b aligned with the upper part 15a. The lower part 15b is finally bent again by 90 ° in order to form a second tread carrier 22, at the end of which a third tread 23 is formed. An explanation of individual features of the door fighter manufactured in this form is given below with reference to FIG.

Alternativ kann der Türkämpfer durch Kanten von Blechplatten mit einer Kantmaschine hergestellt werden. Infolge der Verformung eines einzigen Blechs besteht der erste Laufflächenträger 12 aus zwei aufeinander liegenden Blechabschnitten 12b und 12c. Durch die somit im Vergleich zum Querschnitt des Kastenteils verdoppelte Wanddicke ist für den ersten Laufflächenträger 12 eine erhöhte Stabilität sichergestellt, was im Hinblick auf eine mögliche Abstandsvergrößerung zwischen dem vertikalen Abschnitt 11a und der Lauffläche 13 vorteilhaft ist. Die Stabilität des ersten Laufflächenträgers 12 kann weiter erhöht werden, indem an der dem Schacht abgewandten Außenseite des im wesentlichen vertikalen Abschnitts 11a zwischen dem Teil 15a und dem Teil 15b in dem in Figur 1 mit I bezeichneten Bereich eine Längsschweißnaht gezogen wird, die sich durchlaufend oder mit Unterbrechungen über die gesamte Breite des Türkämpfers in seiner Längsrichtung erstreckt. Alternativ hierzu, oder aber auch in Ergänzung zu der vorgenannten Längsschweißnaht im Bereich I, können die beiden aufeinander liegenden Laufflächenträgerbereiche in dem horizontalen Bereich zwischen dem im wesentlichen vertikalen Abschnitt 11a und dem freien Ende des ersten Laufflächenträgers 12 miteinander durch z.B. Punkt- oder Lochschweißen verbunden und/oder verschraubt sein.Alternatively, the door striker can be made by edges of sheet metal plates with an edging machine. Due to the deformation of a single sheet, the first tread carrier 12 consists of two superimposed sheet metal sections 12b and 12c. By thus doubled compared to the cross section of the box portion wall thickness increased stability is ensured for the first tread carrier 12, which is advantageous in terms of a possible increase in distance between the vertical portion 11a and the tread 13. The stability of the first tread carrier 12 can be further increased by providing a region between the part 15a and the part 15b in the region denoted by I on the outside of the substantially vertical section 11a facing away from the shaft Longitudinal weld is pulled, which extends continuously or intermittently over the entire width of the door striker in its longitudinal direction. Alternatively, or in addition to the aforementioned longitudinal weld in area I, the two superimposed tread carrier areas in the horizontal region between the substantially vertical portion 11a and the free end of the first tread carrier 12 are connected to each other by, for example, spot or hole welding / or bolted.

Figur 2 zeigt den Türkämpfer 10 von Figur 1 in einer Perspektivansicht. Wie aus Figur 2 zu erkennen, erstrecken sich die erste Lauffläche 13 und die zweite Lauffläche 14, die an dem freien Ende 12a des ersten Laufflächenträgers 12 an der dem Schacht zugewandten Innenseite des Kastenteils 11 ausgebildet sind, über die gesamte Breite des Türkämpfers 10 in dessen Längsrichtung. Ein Türblatt bzw. mehrere Türblätter lassen sich somit über die gesamte Breite des Türkämpfers 10 horizontal verschieben.Figure 2 shows the door striker 10 of Figure 1 in a perspective view. As can be seen from FIG. 2, the first running surface 13 and the second running surface 14, which are formed at the free end 12a of the first tread carrier 12 on the inner side of the casing part 11 facing the shaft, extend over the entire width of the door fighter 10 in the latter longitudinal direction. A door leaf or a plurality of door leaves can thus be moved horizontally over the entire width of the door fighter 10.

Der Türkämpfer 10 weist in seinem oberen Bereich 11b ferner Durchgangsbohrungen 17 auf, die für eine entsprechende Befestigung des Türkämpfers 10 an einer Türumfassung oder Schacht- bzw. Fahrkorbwand 45 vorgesehen sind.The door striker 10 has in its upper portion 11b further through holes 17 which are provided for a corresponding attachment of the door striker 10 on a Türumfassung or manhole or car wall 45.

Figur 3 zeigt den voranstehend erläuterten Türkämpfer 10 in einer seitlichen Querschnittsansicht mit einem Türblatt 18, das an dem freien Ende 12a des ersten Laufflächenträgers 12 eingehängt ist. Im einzelnen weist das Türblatt 18 eine obere Türblattaufhängung 19 auf, an der eine Laufrolle 20 angeordnet ist. Vertikal ausgerichtet mit der Laufrolle 20 ist an dem Türblatt 18 ferner eine Gegenrolle 21 angeordnet. Der Abstand zwischen den jeweiligen Achsen der Laufrolle 20 bzw. der Gegenrolle 21 ist dabei so bemessen, daß er mit dem Abstand der ersten Lauffläche 13 von der zweiten Lauffläche 14 abgestimmt ist. Die Querschnittsdarstellung der Figur 3 zeigt deutlich, daß beide Laufrollen 20, 21 über ihre Breite konkav ausgebildet sind, um sich einer konvexen Krümmung der jeweiligen Lauffläche 13, 14 anzupassen. Durch diese Abstimmung der Laufrollen auf ihre zugehörige Lauffläche läßt sich im Ergebnis ein spurtreues Abrollen der Laufrollen und damit eine exakte Längsverschieblichkeit des Türblattes erzielen. Die Laufrolle 20 und die Gegenrolle 21 umfassen das freie Ende 12a von oben und von unten, wodurch eine unerwünschte Vertikalbewegung des Türblattes 18 und somit ein "Entgleisen" des Türblattes ausgeschlossen ist.FIG. 3 shows the above-explained door striker 10 in a lateral cross-sectional view with a door leaf 18 suspended from the free end 12a of the first tread carrier 12. In detail, the door leaf 18 has an upper door leaf suspension 19, on which a roller 20 is arranged. Vertically aligned with the roller 20, a counter-roller 21 is also arranged on the door leaf 18. The distance between the respective axes of the roller 20 and the counter-roller 21 is dimensioned so that it is matched to the distance of the first tread 13 of the second tread 14. The cross-sectional view of Figure 3 clearly shows that both rollers 20, 21 are formed concave over their width in order to adapt to a convex curvature of the respective tread 13, 14. By this vote of the rollers on their associated tread can be achieved in the result a punctual unwinding of the rollers and thus an exact longitudinal displacement of the door leaf. The roller 20 and the counter roller 21 comprise the free end 12a from above and below, whereby an undesirable vertical movement of the door leaf 18 and thus a "derailment" of the door leaf is excluded.

In der Figur 3 oben ist ein Teil einer Wand 45 dargestellt, die hier die obere Kante einer Wandöffnung 46 bildet , in welcher der Türkämpfer 10 als oberer Abschluß der Türöffnung 47 angeordnet ist. Unterhalb dieses Wandteils 45 ist die obere horizontale Abdeckung 11b des Kastenteils 11 angeordnet. Hierbei kann das Kastenteil 11 beispielsweise direkt an der Wand 45 anliegen, oder aber ein Spalt zwischen dem Kastenteil 11 und der Wand 45 (wie in Figur 3 gezeigt) kann geeignet durch ein entsprechendes Dichtmaterial ausgefüllt sein. Der Wandbereich 45, an dem das Kastenteil mit seiner oberen Abdeckung anliegt, kann als Mauerwerk oder aber auch aus Metall und/oder Kunststoff ausgeführt sein. Ferner ist in Figur 3 unten mit Bezugszeichen 47 eine Türöffnung angedeutet, die unterhalb des unteren Endes des unteren Teils 15b beginnt und die nutzbare Türöffnung für den Türbenutzer bildet.In the figure 3 above, a part of a wall 45 is shown, which here forms the upper edge of a wall opening 46, in which the door striker 10 is arranged as the upper end of the door opening 47. Below this wall portion 45, the upper horizontal cover 11 b of the box part 11 is arranged. Here, the box part 11 may, for example, lie directly against the wall 45, or else a gap between the box part 11 and the wall 45 (as shown in FIG. 3) may be suitably filled by a corresponding sealing material. The wall portion 45, on which the box part rests with its upper cover, can be designed as masonry or even made of metal and / or plastic. Further, a door opening is indicated in Figure 3 below with reference numeral 47, which begins below the lower end of the lower part 15 b and forms the usable door opening for the door user.

Die in den Figuren 1 bis 3 erläuterte Ausführungsform des Türkämpfers 10 ist so konzipiert, daß Türblätter in einer Ebene verschoben werden können. Somit eignet sich diese Ausführungsform vorzugsweise für eine einblättrige, seitlich öffnende Schiebetür oder eine zweiblättrige, mittig öffnende Schiebetür. Demgegenüber ist in Figur 4 eine weitere Ausführungsform des erfindungsgemäßen Türkämpfers 10 in einer seitlichen Querschnittsansicht dargestellt, bei der verschiedene Türblätter in nebeneinander liegenden Ebenen geführt sind, so daß sich diese weitere Ausführungsform vorzugsweise für eine zweiblättrige, seitlich öffnende Schiebetür oder für eine vierblättrige, zentral öffnende Schiebetür eignet. Diese weitere Ausführungsform stimmt im wesentlichen mit der in den Figuren 1 bis 3 gezeigten Ausführungsform des Türkämpfers 10 überein, wobei baugleiche Elemente jeweils mit gleichen Bezugszeichen bezeichnet sind. Zur Vermeidung von Wiederholungen sind nachstehend lediglich die relevanten Unterschiede erläutert.The illustrated in Figures 1 to 3 embodiment of the door fighter 10 is designed so that door leaves can be moved in a plane. Thus, this embodiment is preferably suitable for a single-leaf, laterally opening sliding door or a two-leaf, centrally opening sliding door. In contrast, FIG. 4 shows a further embodiment of the door damper 10 according to the invention in a lateral cross-sectional view, in which different door leaves are guided in adjacent planes, so that this further embodiment is preferably for a two-leaf, laterally opening sliding door or for a four-leaf, centrally opening Sliding door is suitable. This further embodiment is substantially the same as the embodiment of the door fighter 10 shown in FIGS. 1 to 3, identical elements being designated by the same reference numerals. To avoid repetition, only the relevant differences are explained below.

Am unteren Ende des unteren Bereichs 15 des Kastenteils 11 (vgl. Fig. 4) erstreckt sich in Richtung Schacht ein zweiter Laufflächenträger 22, der in gleicher Weise wie der erste Laufflächenträger 12 und parallel dazu in Längsrichtung des Türkämpfers 10 verläuft, und an dessen freiem Ende 22a eine dritte Lauffläche 23 ausgebildet ist. Die dritte Lauffläche ist ebenfalls in Form eines nach oben weisenden 180°-Bogens ausgebildet. Die dritte Lauffläche 23 dient als Laufschiene für ein weiteres Türblatt, das seitlich versetzt zu dem oben genannten Türblatt 18 geführt wird, welches an der ersten Lauffläche 13 und der zweiten Lauffläche 14 geführt ist.At the lower end of the lower region 15 of the box part 11 (see Fig. 4) extends toward the shaft, a second tread carrier 22 which extends in the same manner as the first tread 12 and parallel thereto in the longitudinal direction of the door striker 10, and at the free End 22a, a third tread 23 is formed. The third tread is also in the form of an upward-facing 180 ° arc. The third running surface 23 serves as a running rail for a further door leaf, which is guided laterally offset to the above-mentioned door leaf 18, which is guided on the first running surface 13 and the second running surface 14.

Figur 4 verdeutlicht, daß der Abstand zwischen dem senkrechten Teil 11a und den Laufschienen 13 und 14 bei dieser Ausführungsform größer ausgeführt ist als der Abstand zwischen dem senkrechten Teil 11a und der Lauffläche 23. Ferner weist der untere erste Laufflächenträgerbereich 12c des Laufflächenträgers 12 an seiner Unterseite eine vierte Lauffläche 24 auf, die der dritten Lauffläche 23 gegenüberliegend und mit dieser vertikal ausgerichtet ist. Im Hinblick auf eine problemlose Fertigung, bspw. mittels einer Profiliermaschine, ist die vierte Lauffläche 24 in gleicher Weise wie die oben genannten übrigen Laufflächen in Form eines 180°-Bogens ausgebildet. Dabei sind die erste und zweite Lauffläche 13, 14 gegenüber der dritten und vierten Lauffläche 23, 24 seitlich versetzt, so daß hierdurch entsprechend zwei seitlich zueinander versetzte Führungsebenen definiert sind.Figure 4 illustrates that the distance between the vertical part 11a and the rails 13 and 14 is made larger in this embodiment than the distance between the vertical part 11a and the tread 23. Further, the lower first tread support portion 12c of the tread carrier 12 on its underside a fourth tread 24 which is opposite to the third tread 23 and vertically aligned therewith. With regard to a trouble-free production, eg. By means of a profiling, the fourth tread 24 is formed in the same manner as the above-mentioned other treads in the form of a 180 ° arc. In this case, the first and second tread 13, 14 relative to the third and fourth tread 23, 24 laterally offset, so that in accordance with two mutually laterally offset guide planes are defined.

In Figur 5 ist der Türkämpfer 10 von Figur 4 in einer Perspektivansicht dargestellt. Es ist hierin deutlich zu erkennen, daß sich das freie Ende 22a des zweiten Laufflächenträgers 22 parallel zum freien Ende 12a des ersten Laufflächenträgers 12 und seitlich versetzt zu diesem über die gesamte Breite des Türkämpfers 10 in dessen Längsrichtung erstreckt. Dadurch wird eine Verschieblichkeit von zwei nebeneinander laufenden Türblättern ermöglicht, ohne daß diese störend miteinander in Kontakt kommen.In Figure 5, the door striker 10 of Figure 4 is shown in a perspective view. It can be clearly seen herein that the free end 22a of the second tread carrier 22 extends parallel to the free end 12a of the first tread carrier 12 and laterally offset therefrom across the entire width of the door fighter 10 in its longitudinal direction. As a result, a mobility of two side-by-side door leaves is made possible without them interfering with each other.

Figur 6 zeigt eine seitliche Querschnittsansicht des unter Bezugnahme auf die Figuren 4 und 5 erläuterten Türkämpfers 10 mit zwei verschiedenen Türblättern, die entsprechend dem erläuterten seitlichen Versatz der beiden Laufflächen 13, 14 relativ zu den beiden Laufflächen 23, 24 in nebeneinander liegenden Ebenen geführt sind. Hierbei ist neben dem Türblatt 18 an dem Türkämpfer ein weiteres Türblatt 25 eingehängt. Eine an der zugehörigen Türblattaufhängung 41 angebrachte Laufrolle 26 ist auf die dritte Lauffläche 23 aufgesetzt.Figure 6 shows a side cross-sectional view of explained with reference to Figures 4 and 5 door damper 10 with two different door leaves, which are guided according to the explained lateral offset of the two treads 13, 14 relative to the two treads 23, 24 in adjacent planes. Here is next to the Door leaf 18 hinged to the door panel another door leaf 25. A mounted on the associated door leaf suspension 41 roller 26 is placed on the third tread 23.

An der Türblattaufhängung 41 ist oberhalb der Laufrolle 26, und mit dieser vertikal ausgerichtet, ein Gleitelement 27 angebracht, das an seiner der vierten Lauffläche 24 zugewandten Seite eine Nut 28 aufweist. Die Nut 28 ist dabei so bemessen, daß das Gleitelement 27 die vierte Lauffläche umfaßt und dadurch eine Führung des entsprechenden Türblattes 25 sicherstellt. Der Abstand zwischen der Laufrolle 26 und dem Gleitelement 28 ist auf den Abstand zwischen der dritten Lauffläche 23 und der vierten Lauffläche 24 abgestimmt, so daß ein vertikales Abheben der Laufrolle 26 von der dritten Lauffläche und damit ein Entgleisen des Türblattes 25 ausgeschlossen ist. Statt des Gleitelements 27 kann jedoch alternativ auch eine weitere Laufrolle vorgesehen sein, die auf der vierten Lauffläche 24 abrollt und damit eine sichere Führung des Türblattes 25 gewährleistet.On the door leaf suspension 41 is above the roller 26, and aligned vertically with this, a sliding member 27 is mounted, which has a groove 28 on its fourth tread 24 side facing. The groove 28 is dimensioned so that the sliding member 27 comprises the fourth tread and thereby ensures a guide of the corresponding door leaf 25. The distance between the roller 26 and the slider 28 is matched to the distance between the third tread 23 and the fourth tread 24, so that a vertical lifting of the roller 26 from the third tread and thus a derailment of the door leaf 25 is excluded. Instead of the sliding element 27, however, alternatively, a further roller may be provided which rolls on the fourth tread 24 and thus ensures a secure guidance of the door leaf 25.

Im Unterschied zu der anhand der Figuren 1 bis 3 erläuterten Ausführungsform ist an dem Türblatt 18, das an der ersten und zweiten Lauffläche 13, 14 geführt ist, anstelle der Gegenrolle 21 ein Gleitelement 29 angebracht, dessen obere Seite, d.h. die der zweiten Lauffläche 14 zugewandte Seite, eine konkave Krümmung aufweist, die der konvexen Krümmung der zweiten Lauffläche 14 angepaßt ist.In contrast to the embodiment explained with reference to FIGS. 1 to 3, on the door leaf 18, which is guided on the first and second running surfaces 13, 14, instead of the counter-roller 21, there is attached a sliding element 29 whose upper side, i. the second tread 14 facing side has a concave curvature, which is adapted to the convex curvature of the second tread 14.

Aus Figur 6 ist ferner ersichtlich, daß das Gleitelement 27 und das Gleitelement 29 baugleich ausgeführt sein können, was in vorteilhafter Weise zu Kosteneinsparungen führt. Ein solches Gleitelement 27, 29 weist also an seiner einen Seite die der Fläche 24 angepaßte Nut 28 und an seiner anderen Seite eine der Fläche 14 angepaßte Nut auf, und braucht lediglich mit der entsprechend richtigen Ausrichtung an dem Türblatt 18 bzw. an dem Türblatt 25 montiert werden, um die gewünschte Gegenführung für dieses Türblatt zu bilden.From Figure 6 it is also apparent that the sliding member 27 and the sliding member 29 can be made identical, which leads to cost savings in an advantageous manner. Such a sliding element 27, 29 thus has on its one side the groove 28 adapted to the surface 24 and, on its other side, a groove 14 adapted to the surface 14, and need only be mounted with the correspondingly correct orientation on the door leaf 18 or on the door leaf 25 to form the desired counterguide for this door leaf ,

Wie im übrigen aus Figur 6 ersichtlich, schirmen der untere Teil 15b des Kastenteils 11 des Türkämpfers 10 und die Unterseite des Führungsteils 22 auch die dritte Lauffläche 23 und die vierte Lauffläche 24 bzw. die Führung des Türblatts 25 geeignet von dem Benutzer ab, so daß ein verletzungsträchtiger Eingriff in diesen Führungsbereich wirksam ausgeschlossen ist. Da der Türkämpfer 10 wie voranstehend erläutert insgesamt aus einem einzigen gebogenen Blech hergestellt ist, und somit der genannte untere Teil 15b und das Führungsteil 22 Bestandteil des Kastenteils 11 ist, ist keine zusätzliche Konstruktion erforderlich, um die genannte Abschirmung zu gewährleisten.Incidentally, as can be seen from FIG. 6, the lower part 15b of the box part 11 of the door damper 10 and the lower side of the guide part 22 suitably shield the third running surface 23 and the fourth running surface 24 or the guide of the door leaf 25 from the user, so that an infringing intervention in this management area is effectively excluded. Since the door striker 10, as explained above, is made entirely of a single bent sheet metal, and thus the lower part 15b and the guide part 22 are part of the box part 11, no additional construction is required to ensure said shielding.

Ähnlich zu der Darstellung in Figur 3 ist in Figur 6 links oben ein Bereich einer Wand 45 gezeigt, als oberer Bereich einer Wandöffnung 46, gegen den der obere Teil 15a des im wesentlichen vertikalen Abschnitts 11a anliegt. Hierbei bildet ein Stahlträger den Wandabschluß über der Wandöffnung 46. Dazu ist unten eine Türöffnung 47 angedeutet, die unterhalb des zweiten Laufflächenträgers 22 beginnt. Im Unterschied zu der in Figur 3 gezeigten Ausführungsform ist das Blech im Anschluß an die dritte Lauffläche 23 verkürzt ausgeführt, was eine noch einfachere Profilierung des Blechs in diesem Bereich gewährleistet.Similar to the illustration in FIG. 3, a region of a wall 45 is shown at the top left in FIG. 6 as the upper region of a wall opening 46, against which the upper part 15a of the substantially vertical section 11a abuts. Here, a steel support forms the wall termination over the wall opening 46. For this purpose, a door opening 47 is indicated below, which begins below the second tread carrier 22. In contrast to the embodiment shown in Figure 3, the sheet is made shortened following the third tread 23, which ensures an even easier profiling of the sheet in this area.

Figur 7 zeigt den erfindungsgemäßen Türkämpfer in einer weiteren Ausführungsform, bei der drei nebeneinander angeordnete Türblattführungen vorgesehen sind. Hierbei weist jede Türblattführung eine Haupt- und eine Gegenführungsfläche auf. Im einzelnen weist hierbei der Türkämpfer außer dem ersten Laufflächenträger 12 und dem zweiten Laufflächenträger 22 noch einen dritten Laufflächenträger 62 auf, an dem in gleicher Weise an einem freien Ende davon zwei Laufflächen ausgebildet sind. Mit weiteren Faltungen oder der Anordnung von Faltungen an anderen Stellen des Türkämpferquerschnitts lassen sich weitere Führungsflächen, oder auch anders angeordnete Führungsflächen, schaffen. Mittels der weiteren Faltungen von Blechbereichen in Längsrichtung des Türkämpfers mit entsprechenden Ausformungen können können an jeder gewünschten Stelle im Querschnitt des Türkämpfers weitere Laufflächen gebildet werden.Figure 7 shows the door according to the invention in a further embodiment in which three juxtaposed Door leaf guides are provided. In this case, each door leaf guide has a main and a counter guide surface. In detail, in this case the door impactor, in addition to the first tread carrier 12 and the second tread carrier 22, also has a third tread carrier 62 on which two running surfaces are formed in the same way at a free end thereof. With further folds or the arrangement of folds at other locations of the doorstep cross section, further guide surfaces or else differently arranged guide surfaces can be created. By means of the further folding of sheet metal areas in the longitudinal direction of the door fighter with corresponding formations, further running surfaces can be formed at any desired point in the cross section of the door fighter.

Die Erfindung ist nicht auf die in der Zeichnung dargestellten und in der Figurenbeschreibung beschriebenen Ausführungsformen beschränkt. Der Türkämpfer ist zum Einsatz bei einer Aufzugeinrichtung geeignet und kann über einer Fahrkorbtüröffnung oder einer Stockwerktüröffnung angebracht sein.The invention is not limited to the embodiments shown in the drawing and described in the description of the figures. The door striker is suitable for use with a lift and may be mounted above a car door opening or landing door opening.
