Definitions
- the invention relates to the locking device of a sliding door or a sliding door, which ensures that after reaching the locking position even with powerless door drive, the door remains in its locking position when forces of various kinds act on them, according to the preamble of claim and the DE 86 01 065 U ,
- This document describes a rotary latch for sliding or sliding doors of vehicles, especially rail vehicles, by which a locking bolt which is connected to a door leaf, is fixed in its closed position.
- the device is complex and has a large footprint, beyond their adjustment is complex. To an even greater extent, this applies to the devices according to the FR 1 321 314 and the EP 626 494 ,
- the invention now has the object to provide a locking device of the initially mentioned type, which does not have the disadvantages mentioned, but compact, with little effort operable and easy to arrange and adjust.
- the locking takes place by means of acting on a drive rod locking lever, which in turn is moved via a toggle mechanism between its open position and its locked position.
- a drive rod locking lever which in turn is moved via a toggle mechanism between its open position and its locked position.
- the device is explained in more detail below with reference to the drawing, without being limited thereto. It shows the Fig. 1 the main components of the device according to the invention, the Fig. 2 the locking unit as a whole, the Fig. 3 the force relationships on the locked unit and the Fig. 4 the kinematic processes during locking and unlocking.
- the Fig. 1 shows, purely schematically the most essential components of a locking device according to the invention 1.
- the device 1 serves a locking bolt 2, which is fixedly connected to a door leaf (not shown), in the closed position of the door, in which he the in Fig. 1 shown position to fix.
- This fixation is effected by means of a pawl 3, which is pivotable about a carriage box fixed pivot point of the pawl axis 4.
- the movement of the locking bolt 2 with respect to the pawl axis 4 is substantially parallel to the axial direction of a guide rod 5, which is fastened by means of a fastening device 6 on the car body.
- the guide rod 5 has a notch 9 which cooperates with a locking element 11 of a locking lever 10.
- the locking lever 10 is pivotally mounted about a carriage axis fixed lever axis 12 and is acted upon by a spring 21 with torque around the lever axis, that its locking element is urged out of the notch when no further forces or moments act on him.
- the locking lever 10 is on its side facing away from the locking element 11 under the action of a toggle mechanism 13 which is rotatably mounted about a carriage axis fixed knee axis 14 and in turn is under the action of a drive rod 15 of an actuator 16.
- the actuator is able to displace the drive rod 15 in its axial direction and is about a parallel to the axes 4, 12 and 14, in Fig. 2 shown axis 18 rotatable.
- the Fig. 2 shows how these components are stored by a mounting plate 17 combined to form a unit, so that no adjustment during installation on the door frame is necessary, as just the correct positioning relative to the locking pin 2 of the (not shown) door leaf.
- the mounting plate 17 may of course have a deviating from the flat plate shape and in particular the different axes each have above and below the rotatably mounted by the axis component bearing, so it is possible to find with small and inexpensive bearings Aus GmbH.
- the mounting of the guide rod 5 on the mounting plate 17 is provided.
- the actuator axis 18 visible and also on the side facing away from the toggle mechanism 13 side of the actuator 16 arranged Notbetuschistsvorraum that makes the manual opening of the door by the passengers or operator in the event of failure of the drive energy.
- the Fig. 3 shows, purely schematically, the interaction of the individual parts between the actuator 16 to the guide rod 5 under the action of a force acting on the door leaf, thus the locking pin 2, the pawl 3 and thus the guide rod 5 opening force F.
- Due to the oblique end face of the notch 9 and the corresponding oblique contact surface of the locking element 11 is, depending on the friction between these surfaces, extending from the axis extending in the axis of the guide rod 5 opening force F component F Normal , the locking lever 10 substantially in the lever direction, with a small amount of bending through the oblique course, applied, which leads to a corresponding load on the bearing of the lever axis 12 and to an extremely low Force component normal to the introduced force F on the toggle mechanism 13.
- the Fig. 4 shows the kinematic sequence of a locking-unlocking process from top to bottom:
- the Fig. 4a shows the locking mechanism 1 in its open position: the locking pin 2 moves in the direction of arrow V in the open area of the pawl 3 and pulls, as from a synopsis of Fig. 4a and 4b it can be seen, the movable part of the guide rod 5 against the force of the spring 8 at the end of the movement of the locking bolt 2 in the in Fig. 4b shown position.
- the notch 9 enters the region of the locking element 11 and the locking lever 10, against the force of the lever spring 21, by the toggle mechanism 13, which is then activated, pushed down until the in Fig. 4b shown position is reached with the locking element 11 in the notch 9.
- those on the basis of Fig. 3 described static forces and the locking device 1 locks the locking pin 2 in the powerless state of the actuator 16th
- the actuator is first acted upon so that he the toggle mechanism 13 about the knee axis 14 in the in Fig. 4c pivoted position shown, thereby passes the locking lever 10 under the action of its lever spring 21 in the upper position in which the locking element 11 passes from the notch 9 and thus the guide rod 5 releases, now under the action of the spring 8 (in the illustration to the left ), whereby the pawl 3 releases the locking pin 2 and this can open in the direction of the arrow V 'with the door leaf.
- the invention is not limited to the illustrated embodiment, but may be variously modified.
- the locking member 11 and the notch 9 need not have the shape shown, but can be configured differently, the storage and the proportion of the locking lever 10 must not be selected as shown and
- the guide rod 5 may be designed differently. It is essential that the toggle mechanism 13 is in the locked position in an over-dead-center position, in the manner typical of such mechanisms, in which the force acting on it via the roller 20 does not cause any moment in the opening direction on it. This characteristic characteristic of toggle mechanisms can easily be determined and determined by those skilled in the art of kinematics and the locking devices of doors with knowledge of the invention.
- either the two door leaves are kinematically connected to each other, so that the arrangement of a locking bolt 2 is sufficient for both door leaves, or, if the individual operation of the door leaves is desired, such a locking device 1 must be provided for each of the two door leaves.
- the two devices can be arranged on a common mounting plate, whereby the installation is further simplified.
- the locking mechanism according to the invention can be combined with all types of door operators, it only has to be coordinated with its activation of the door drive via the door electronics.

Description
Die Erfindung betrifft die Verriegelungsvorrichtung einer Schiebetür bzw. einer Schwenkschiebetür, durch die sichergestellt wird, dass nach erreichter Verriegelungslage auch bei kraftlosem Türantrieb die Tür auch dann in ihrer Verriegel-Position bleibt, wenn Kräfte unterschiedlichster Art auf sie einwirken, entsprechend dem Oberbegriff des Anspruches und dem
Diese Druckschrift beschreibt eine Drehfallenverriegelung für Schiebetüren bzw. Schwenkschiebetüren von Fahrzeugen, insbesondere von Schienenfahrzeugen, durch die ein Verriegelungsbolzen, der mit einem Türblatt verbunden ist, in seiner Geschlossen-Position fixiert wird. Die Vorrichtung ist komplex und weist einen großen Platzbedarf auf, darüber hinaus ist ihre Justierung aufwändig. In noch größerem Ausmaß gilt dies von den Vorrichtungen gemäß der
Allgemein gibt es derartige Verriegelungsvorrichtungen im Stand der Technik verschiedentlich, zumeist sind sie vom eigentlichen Türantrieb unabhängig und selbständig ausgebildet und eingebaut, was zwar eine eigene Montage, Justierung, Wartung etc. notwendig macht, sie aber unabhängig vom eigentlichen Türantrieb macht.Generally there are such locking devices in the prior art variously, mostly they are independent of the actual door drive and independently trained and installed, which makes its own installation, adjustment, maintenance, etc. necessary, but makes them independent of the actual door drive.
Andere Verriegelungsvorrichtungen wirken auf den Türantrieb ein und fixieren ihn in der Position die seiner Geschlossen-Lage entspricht, doch leiden diese Systeme daran, dass es notwendig ist, die Lage gegen große Kräfte zu halten, was entweder große Verriegelungskräfte oder lange Verriegelungswege notwendig macht, beides wird wegen des geringen zur Verfügung stehenden Platzes und des Wunsches, mit geringen Kräften und damit mit kleinen Stellmotoren auszukommen, nicht gerne gesehen.Other locking devices act on and immobilize the door drive in the position corresponding to its closed position, but these systems suffer from the need to maintain the position against large forces, requiring either large locking forces or long locking paths, both Because of the small available space and the desire to get along with small forces and thus with small actuators, not gladly seen.
Die Erfindung hat nun das Ziel, eine Verriegelungsvorrichtung der eingangs genannten ersten Art anzugeben, die die genannten Nachteile nicht aufweist, sondern kompakt, mit wenig Kraftaufwand betreibbar und leicht anzuordnen und zu justieren ist.The invention now has the object to provide a locking device of the initially mentioned type, which does not have the disadvantages mentioned, but compact, with little effort operable and easy to arrange and adjust.
Diese Ziele werden erfindungsgemäß dadurch erreicht, dass die Verriegelung mittels eines auf eine Antriebsstange wirkenden Verriegelungshebels erfolgt, der seinerseits über einen Kniehebelmechanismus zwischen seiner Offen-Position und seiner Verriegelt-Position bewegt wird. Durch den Verriegelungshebel ist es möglich, mit einem geringen Weg des Aktuators für den Kniehebelmechanismus auszukommen, da der tatsächliche Verriegelungsweg über den Hebel nahezu beliebig verändert werden kann, der Kniehebelmechanismus wiederum führt zu einer vollständigen kraftmäßigen Entkoppelung zwischen dem Aktuator und dem Verriegelungselement des Verriegelungshebels, sodass der Aktuator nur mehr während der Änderung der Position des Verriegelungshebels mit Kraft beaufschlagt sein muss, wobei der dafür notwendige Kraftbedarf extrem klein ist.These objects are inventively achieved in that the locking takes place by means of acting on a drive rod locking lever, which in turn is moved via a toggle mechanism between its open position and its locked position. By the locking lever, it is possible to make do with a small way of the actuator for the toggle mechanism, since the actual locking path can be changed almost arbitrarily via the lever, the toggle mechanism in turn leads to a complete decoupling force between the actuator and the locking element of the locking lever, so that the actuator only has to be acted upon during the change of the position of the locking lever with force, with the necessary power requirement is extremely small.

Die Führungsstange 5 weist eine Einkerbung 9 auf, die mit einem Verriegelungselement 11 eines Verriegelungshebels 10 zusammenwirkt. Der Verriegelungshebel 10 ist um eine wagenkastenfeste Hebelachse 12 schwenkbar gelagert und wird von einer Feder 21 so mit Drehmoment um die Hebelachse beaufschlagt, dass sein Verriegelungselement aus der Einkerbung gedrängt wird, wenn keine weiteren Kräfte bzw.

Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt, sondern kann verschiedentlich abgewandelt werden. So kann statt des dargestellten auf Magnetbasis basierenden Aktuators 16 ein anderer vorgesehen sein, das Verriegelungselement 11 und die Einkerbung 9 müssen nicht die dargestellte Form haben, sondern können anders ausgestaltet werden, die Lagerung und die Proportion des Verriegelungshebels 10 muss nicht wie dargestellt gewählt werden und auch die Führungsstange 5 kann anders ausgebildet sein. Wesentlich ist, dass sich der Kniehebelmechanismus 13 auf die für solche Mechanismen typische Weise in der Verriegelt-Position in einer Über-Totpunkt-Lage befindet, in der die auf ihn über die Rolle 20 einwirkende Kraft kein Moment in Öffnungsrichtung an ihm bewirkt. Diese für Kniehebelmechanismen typische Eigenschaft kann vom Fachmann auf dem Gebiete der Kinematik und der Verriegelungsvorrichtungen von Türen in Kenntnis der Erfindung leicht bestimmt und festgelegt werden.The invention is not limited to the illustrated embodiment, but may be variously modified. Thus, instead of the illustrated magnetic based
Bei zweiflügeligen Türen sind entweder die beiden Türblätter miteinander kinematisch verbunden, sodass die Anordnung eines Verriegelungsbolzens 2 für beide Türblätter ausreichend ist, oder es sind, wenn der Einzelbetrieb der Türblätter erwünscht ist, für jedes der beiden Türblätter eine solche Verriegelungsvorrichtung 1 vorzusehen. Selbstverständlich können in diesem Fall die beiden Vorrichtungen auf einer gemeinsamen Montageplatte angeordnet sein, wodurch der Einbau weiter vereinfacht wird. Wie aus der Beschreibung und der Zeichnung leicht ersichtlich ist, kann der erfindungsgemäße Verriegelungsmechanismus mit allen Arten von Türantrieben kombiniert werden, es muss nur seine Aktivierung mit der des Türantriebs über die Türelektronik koordiniert werden.In the case of double-leaf doors, either the two door leaves are kinematically connected to each other, so that the arrangement of a
