Description

Die Erfindung betrifft einen Türriegelanschlag, insbesondere für Schwenkschiebetüren von Fahrzeugen, gemäss dem Oberbegriff des Patentanspruches 1.The invention relates to a door latch stop, in particular for pivoting sliding doors of vehicles, according to the preamble of patent claim 1.

Bei Eisenbahnwaggontüren reicht der seitliche Druck der Führungen meistens nicht aus, um das Türblatt fest an die Dichtungen anzupressen. Daher ist es erforderlich, Einrichtungen vorzusehen, die das geschlossene, also mit dem Türriegel bereits eingerastete Türblatt gegen den Wagenkasten ziehen und damit dicht festlegen. Bei einem bekannten Türriegelanschlag (DE-U-7873194) ist ein Schwenkhebel vorgesehen, der von einem mit einem Druckmittel beaufschlagten Zylinder betätigt wird. Dieser als Teil eines Schubelementes ausgebildeter Schwenkhebel ist in Schubrichtung gekrümmt und greift in seiner Endstellung in eine am Türblatt angebrachte bogenförmige Aussparung ein. Dabei wird dem eingeschobenen Türblatt eine zusätzliche Schiebebewegung erteilt und in seiner Schliesslage ein Einziehen des Türblattes in den Portalrahmen mit der Folge erreicht, dass das Türblatt sicher in den Türverschluss einfährt. Der Schwenkhebel wird mittels eines Antriebgestänges oder auch durch einen pneumatischen Antrieb betätigt. Ein zur Absicherung der Schiebetür in der Schliessstellung vorhandener Türriegel ist als getrennter, selbständiger Riegelmechanismus ausgebildet, wodurch ein nicht unbedeutender Mehraufwand entsteht. Da dieser Türriegel erst einschnappen kann, wenn das Türblatt durch den Schubmechanismus in die geschlossene Endlage gebracht worden ist, ist das Türblatt bis dahin nur durch den Schwenkhebel gesichert, was in der Praxis nicht immer ausreicht, weil der Schwenkhebel bei offener Tür durch Manipulation zurückgedrückt werden und er dann das Türblatt nicht mehr erfassen kann.With railroad car doors, the lateral pressure of the guides is usually not sufficient to press the door leaf firmly against the seals. It is therefore necessary to provide devices which pull the closed door leaf, that is to say the door leaf which has already been latched in, against the car body and thus fix it tightly. In a known door latch stop (DE-U-7873194) a pivot lever is provided which is actuated by a cylinder which is pressurized with a pressure medium. This swivel lever, which is designed as part of a push element, is curved in the push direction and, in its end position, engages in an arcuate cutout in the door leaf. The inserted door leaf is given an additional sliding movement and, in its closed position, the door leaf is drawn into the portal frame with the result that the door leaf securely moves into the door lock. The swivel lever is operated by means of a drive linkage or also by a pneumatic drive. A door bolt present to secure the sliding door in the closed position is designed as a separate, independent bolt mechanism, which results in a not inconsiderable additional effort. Since this door latch can only snap in when the door leaf has been brought into the closed end position by the push mechanism, the door leaf is only secured by the pivot lever until then, which in practice is not always sufficient because the pivot lever is pushed back by manipulation when the door is open and then he can no longer grasp the door leaf.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Türriegelanschlag zu schaffen, der einfacher und sicherer ist.The invention is therefore based on the object of creating a door latch stop which is simpler and safer.

Diese Aufgabe wird an einem Türriegelanschlag gemäss dem Oberbegriff des Patentanspruches 1 erfindungsgemäss durch die Kennzeichnungsmerkmale dieses Patentanspruches gelöst.This object is achieved according to the invention on a door latch stop according to the preamble of patent claim 1 by the characterizing features of this patent claim.

Bei dem erfindungsgemässen Türriegelanschlag schnappt der Türriegel vor dem Schwenkhebel ein, so dass das Türblatt bereits gefangen ist und nicht mehr aufgehen kann. Erst hierauf wird das Türblatt durch den Schwenkhebel in die Endlage gebracht, um einen vollkommen dichten Abschluss zu erreichen. Selbst bei einer Störung am Schwenkhebelmechanismus wird eine sichere, wenn auch keine dichte Türblatthalterung gewährleistet. Beide Mechanismen sind zu einer Baueinheit zusammengefasst, wodurch eine erhebliche Vereinfachung erreicht wird.With the door latch stop according to the invention, the door latch snaps in front of the pivot lever, so that the door leaf is already caught and can no longer open. Only then is the door leaf brought into the end position by the swivel lever in order to achieve a completely tight seal. Even if the swivel lever mechanism malfunctions, a secure, if not leak-proof door leaf holder is guaranteed. Both mechanisms are combined into one unit, which considerably simplifies them.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels, das auch in der Zeichnung dargestellt ist, näher beschrieben. Es zeigen:

  • Fig. 1 eine Ansicht,
  • Fig. 2 einen Schnitt nach der Linie 11-11 der Fig. 1 und
  • Fig. 3 einen Detailschnitt nach der Linie 111-111 in Fig. 2.
The invention is described below with reference to an embodiment which is also shown in the drawing. Show it:
  • 1 is a view
  • Fig. 2 shows a section along the line 11-11 of Fig. 1 and
  • 3 shows a detail section along the line 111-111 in FIG. 2.

Wie man aus der Zeichnung erkennen kann, rastet ein Türriegel 14 eines nicht dargestellten Türblattes in der Schliessstellung hinter einem Anschlag 2 eines am nicht dargestellten Wagenkasten befestigten Gusskörpers 1 ein. Um den Türriegel 14 und damit das Türblatt noch weiter gegen den Wagenkasten ziehen zu können, ist im Gusskörper 1 ein Schwenkhebel 3 mittels eines Bolzens 4 schwenkbar gelagert, der mit einer Nase 5 ebenfalls am Türriegel 14 anliegt. Der Schwenkhebel 3 wird durch einen pneumatischen Zylinder 6 nach Schliessen des Türblattes im Uhrzeigersinn geschwenkt, wodurch die Nase 5 den Türriegel 14 und damit das Türblatt vom Anschlag 2 abhebt und nach innen verschiebt, wodurch ein festes Anpressen des Türblattes an die Dichtungen erreicht wird.As can be seen from the drawing, a door latch 14 of a door leaf (not shown) engages in the closed position behind a stop 2 of a cast body 1 fastened to the car body (not shown). In order to be able to pull the door latch 14 and thus the door leaf even further against the car body, a pivot lever 3 is pivotably mounted in the cast body 1 by means of a bolt 4, which also rests on the door latch 14 with a nose 5. The pivot lever 3 is pivoted by a pneumatic cylinder 6 after closing the door leaf in a clockwise direction, whereby the nose 5 lifts the door latch 14 and thus the door leaf from the stop 2 and moves inwards, whereby a firm pressing of the door leaf against the seals is achieved.

Damit diese Bewegungen erst nach Einrasten des Türblattes des Türriegels 14 hinter den Anschlag 2 bzw. die Nase 5 erfolgen, ist in eine Druckmittelzuleitung 10 zum Zylinder 6 ein Ventil 7 eingeschaltet, welches durch einen vom Türblatt betätigten Anschlag 9 gesteuert ist und das erst dann die Druckluftzufuhr zum Zylinder 6 freigibt, der ansonsten mit dem Türbetätigungsmechanismus parallel geschalten ist. Durch diese Verzögerung gegenüber dem Türbetätigungszylinder wird erreicht, dass der Zylinder 6 erst nach Schliessen in Tätigkeit tritt und nicht durch vorzeitiges Anziehen ein Einrasten des Türriegels 14 überhaupt verhindert.So that these movements only take place after the door leaf of the door bolt 14 engages behind the stop 2 or the nose 5, a valve 7 is switched into a pressure medium supply line 10 to the cylinder 6, which valve is controlled by a stop 9 actuated by the door leaf, and only then Compressed air supply to cylinder 6, which is otherwise connected in parallel with the door operating mechanism. This delay in relation to the door actuating cylinder means that the cylinder 6 only comes into operation after it has been closed and does not prevent the door bolt 14 from snapping into place at all due to premature tightening.

Um auch ein selbsttätiges (ferngesteuertes) Öffnen der Tür zu ermöglichen, ist auf beiden Seiten des Schwenkhebels 3 je ein über einen Druckluftzylinder 12 betätigter Stössel 11 vorgesehen, der durch eine Rückholfeder 13 gehalten, bei Druckluftzufuhr 15 zum Zylinder 12 gegen den Türriegel 14 stösst, diesen damit zurückschiebt und ausser Eingriff mit dem Anschlag 2 bzw. der Nase 5 bringt.In order to also enable automatic (remote-controlled) opening of the door, a plunger 11, actuated by a compressed air cylinder 12, is provided on both sides of the pivoting lever 3, which is held by a return spring 13 and, when the compressed air supply 15 to the cylinder 12 abuts against the door latch 14, pushes it back and disengages the stop 2 or the nose 5.

Die Erfindung ist auf das dargestellte Ausführungsbeispiel nicht beschränkt. So kann anstelle von zwei Stösseln 11 auch nur einer Verwendung finden. Es kann ferner der Zylinder 6 doppelwirkend ausgebildet werden und der Anschlag 2 und die Stössel 11 fortbleiben, so dass die Entriegelung bzw. Öffnung der Tür nur durch eine der Verriegelung entgegengesetzte Schwenkung des Schwenkhebels 3 bewirkt wird, ihn gegen den Uhrzeigersinn schwenkt und damit den Türriegel 14 freigibt. Anstelle von mittels Pressluft betätigten Zylindern 6, 12 können selbstverständlich auch Elektromagnete treten. Auch kann anstelle eines Schieberventils 7 eine andere Ventilart eingesetzt werden.The invention is not limited to the illustrated embodiment. Thus, only one can be used instead of two plungers 11. The cylinder 6 can also be double-acting and the stop 2 and the plunger 11 remain so that the unlocking or opening of the door is effected only by pivoting the pivoting lever 3 in the opposite direction, pivoting it counterclockwise and thus pivoting the door latch 14 releases. Instead of cylinders 6, 12 actuated by compressed air, electromagnets can of course also be used. Another type of valve can also be used instead of a slide valve 7.
