Abstract

In order to secure a vehicle door (1), especially of rail vehicles, in its closing position, a spring-loaded latch (6) actuated from the door lock via a tension rod (5) is assigned a closing hook (8) which is fastened to the door jamb and in which the latch (6) engages when the door is closed. Mounted rotatably on this closing hook (8) is a clamping claw (9) which engages with its nose (20) into the latch (6) and which via a pressure cylinder (11) presses the latch together with the door leaf into the closing position. <IMAGE>

Description

Die Erfindung betrifft eine Verriegelung für Fahrzeugtüren, insbesondere von Schienenfahrzeugen, mit einer von einem Türschloß her über eine Zugstange betätigten, federbelasteten Falle, die hiner einem Schließhaken einrastet.The invention relates to a lock for vehicle doors, in particular rail vehicles, with a spring-loaded latch which is actuated by a door lock via a pull rod and which engages behind a locking hook.

Bei Fahrzeugen ist es erforderlich, Verriegelungen anzuwenden, die unter allen Umständen sicher funktionieren und beim Schließen schon bei geringem Anpreßdruck ein sicheres Fangen des Türblattes gewährleisten, was insbesondere bei Schwenkschiebetüren schwierig ist. Der dabei erzielbare Schließdruck genügt in der Regel nicht, ein sattes Anpressen des Türblattes an die Dichtungen herbeizuführen.In vehicles, it is necessary to use interlocks that work safely under all circumstances and ensure that the door leaf is caught securely even when the contact pressure is low, which is particularly difficult with pivoting sliding doors. The closing pressure that can be achieved is generally not sufficient to bring the door leaf firmly into contact with the seals.

Der Erfindung liegt daher die Aufgabe zugrunde, für Fahrzeugtüren eine Verriegelung zu schaffen, die das Türblatt in die Schließstellung drückt und in dieser Stellung sicher festhält.The invention is therefore based on the object of creating a locking mechanism for vehicle doors, which is the door leaf presses into the closed position and holds it securely in this position.

Diese Aufgabe wird erfindungsgemäß an einer Verriegelung der eingangs genannten Art dadurch gelöst, daß am Schließhaken drehbar eine von einem Druckzylinder oder Elektromagnet betätigte Spannklaue vorgesehen ist, die mit einer Nase in die Falle eingreift und bei Betätigung durch den Druckzylinder das geschlossene Türblatt stark an die Dichtung anpreßt.This object is achieved in a lock of the type mentioned in that a clamping claw actuated by a pressure cylinder or electromagnet is rotatably provided on the locking hook, which engages with a nose in the case and, when actuated by the pressure cylinder, the closed door leaf strongly against the seal presses.

Weitere Merkmale der Erfindung sind in den Unteransprüchen erwähnt.Further features of the invention are mentioned in the subclaims.

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

  • Fig. 1 ein Türblatt in Seitenansicht,
  • Fig. 2 ein vergrößertes Detail X der Figur 1,
  • Fig. 3 einen Schnitt nach der Linie III-III der Figur 2 und
  • Fig. 4 einen Schnitt nach der Linie IV-IV der Figur 2.
The invention is described below with reference to an embodiment which is also shown in the drawing. Show it:
  • 1 is a door leaf in side view,
  • 2 shows an enlarged detail X of FIG. 1,
  • Fig. 3 shows a section along the line III-III of Figure 2 and
  • 4 shows a section along the line IV-IV of FIG. 2.

Wie man aus der Zeichnung erkennen kann, besteht der Schließmechanismus einer Tür 1 aus einem Schloß 2, das über ein Gestänge von einem Außentürgriff 4 und einem Innentürgriff 3 zu betätigen ist, wobei über eine Zugstange 5 ein Riegelmechanismus X ausgelöst wird. Dieser Riegelmechanismus besteht, wie insbesondere in Figur 3 veranschaulicht ist, aus einer durch eine Feder 7 belasteten Falle 6, die über die Zugstange 5 betätigt wird und beim Schließen hinter einem Schließhaken 8, der an einem Türstock angebracht ist, einrastet. Der Schließhaken 8 ist gabelförmig ausgebildet, wobei zwischen den Gabelschenkeln eine um eine Achse 13 drehbare Spannklaue 9 angeordnet ist, die mittels einer Nase 20 mit der Falle 6 zusammenwirkt. Die Betätigung der Spannklaue 9 erfolgt durch einen doppelt wirkenden Druckluftzylinder 11, dessen Kolbenstange 10 über einen Bolzen 12 an der Spannklaue angelenkt ist.As can be seen from the drawing, the closing mechanism of a door 1 consists of a lock 2, which can be actuated via a linkage from an outer door handle 4 and an inner door handle 3, a locking mechanism X being triggered via a pull rod 5. This locking mechanism consists, as illustrated in particular in Figure 3, of a spring 6 loaded by a spring 6, which is actuated via the pull rod 5 and engages when closed behind a locking hook 8, which is attached to a door frame. The locking hook 8 is fork-shaped, with between the Fork legs a clamping claw 9 rotatable about an axis 13 is arranged, which cooperates with the catch 6 by means of a nose 20. The clamping claw 9 is actuated by a double-acting compressed air cylinder 11, the piston rod 10 of which is articulated to the clamping claw via a bolt 12.

Wird nun das Türblatt 1 mechanisch oder von Hand geschlossen, so rastet die federbelastete Falle 6 am Schließhaken 8 ein, worauf durch Betätigung des Druckluftzylinders 11 die Spannklaue 9 betätigt wird und mit ihrer Nase 20 die Falle 6 nach innen drückt, wodurch das Türblatt 1 an die Dichtung 19 angepreßt wird.If the door leaf 1 is now closed mechanically or by hand, the spring-loaded latch 6 engages on the locking hook 8, whereupon the clamping claw 9 is actuated by actuation of the compressed air cylinder 11 and presses the latch 6 with its nose 20 inward, as a result of which the door leaf 1 is pressed the seal 19 is pressed.

Die erfindungsgemäße Verriegelung ist jedoch nicht nur zum Schließen und Anpressen geeignet, sondern kann auch mechanisch ferngesteuert die Tür entriegeln. Zu diesem Zweck wird der doppelt wirkende Zylinder 11 in die Gegenrichtung beaufschlagt, wodurch die Spannklaue 9 eine der Anpreßbewegung entgegengerichtete Bewegung ausführt und über einen an ihrer Achse 13 befestigten Nocken 14 eine Druckplatte 18 verschiebt, die auf einem Bolzen 17 befestigt ist, der zur Verdrehsicherung einen Rechteckquerschnitt aufweist. An diesem Bolzen 17 ist auch ein Stift 16 angeordnet, der eine Rücknahme der Druckplatte bewirkt. Die Druckplatte 18 drückt gegen einen Anschlag 15, der sich seitlich an der Falle 6 befindet, wodurch diese entgegen der Kraft der Feder 7 zurückgeschoben und damit außer Eingriff mit dem Schließhaken 8 bzw. der Spannklaue 9 gebracht wird. Die Tür springt dann auf und kann dann von Hand oder über einen mechanischen Schließmechanismus geöffnet werden.The lock according to the invention is not only suitable for closing and pressing, but can also unlock the door mechanically by remote control. For this purpose, the double-acting cylinder 11 is acted upon in the opposite direction, as a result of which the clamping claw 9 executes a movement opposite to the pressing movement and displaces a pressure plate 18 via a cam 14 fastened to its axis 13, which pressure plate is fastened on a bolt 17, which prevents rotation has a rectangular cross section. A pin 16 is also arranged on this pin 17, which causes the pressure plate to be withdrawn. The pressure plate 18 presses against a stop 15 which is located on the side of the latch 6, as a result of which the latter is pushed back against the force of the spring 7 and is thus disengaged from the locking hook 8 or the clamping claw 9. The door then opens and can then be opened by hand or via a mechanical locking mechanism.

Die Erfindung ist auf das dargestellte Ausführungsbeispiel nicht beschränkt. So kann anstelle eines pneumatischen oder hydraulischen Druckzylinders 11 auch ein Elektromagnet treten und bei entsprechender Anordnung des Zylinders 11 kann auch auf die Druckplatte 18 und den Bolzen 17 verzichtet werden, wobei der Nocken 14 direkt auf die Falle 6 einwirkt.The invention is not limited to the illustrated embodiment. So instead of a pneuma table or hydraulic pressure cylinder 11 also an electromagnet and with a corresponding arrangement of the cylinder 11 can also be dispensed with the pressure plate 18 and the bolt 17, the cam 14 acting directly on the case 6.
