Description

Die vorliegende Erfindung betrifft eine Entriegelungsvorrichtung für Fahrzeuge des öffentlichen Verkehrs.The present invention relates to an unlocking device for public transport vehicles.

Fahrzeuge des öffentlichen Verkehrs weisen in der Regel eine Vielzahl Türen auf, beispielsweise Schiebe-Schwenk-, oder Schwenkschiebetüren. Wesentlich ist, dass die Türen zum einen sicher verriegelbar, zum anderen aber auch schnell und einfach entriegelbar sein müssen. Hierzu eignen sich beispielsweise Drehfallenschlösser, die die Türen während der Fahrt sicher verriegeln. Bei einem geplanten Halt oder auch im Falle eines Notstopps können diese Türschlösser schnell und einfach entriegelt werden.Public transport vehicles generally have a plurality of doors, such as sliding pan, or sliding doors. It is essential that the doors on the one hand safely lockable, on the other hand also have to be quickly and easily unlocked. For this purpose, for example, rotary latch locks that securely lock the doors while driving. With a planned stop or even in the event of an emergency stop, these door locks can be unlocked quickly and easily.

Beispielsweise zeigt die EP 1293368 eine Vorrichtung zum Öffnen und Schließen einer Dreh-Schiebetür für Kraftfahrzeuge. Eine Umlenkrolle ist über zwei Bowdenzüge mit zwei Drehschlössern verbunden, die an einer Portalsäule angeordnet sind. Die Umlenkrolle ist über einen Hubmagneten aktivierbar. Die Vorrichtung ist insgesamt aufwendig konstruiert, benötigt relativ viel Bauraum und, besteht aus einer Vielzahl an Bauteilen.For example, the shows EP 1293368 a device for opening and closing a revolving-sliding door for motor vehicles. A pulley is connected via two Bowden cables with two rotary locks, which are arranged on a portal column. The pulley can be activated via a lifting magnet. The device is constructed overall complex, requires a relatively large amount of space and, consists of a variety of components.

Die Aufgabe der Erfindung besteht darin, eine möglichst kompakte und einfach aufgebaute Entriegelungsvorrichtung für Fahrzeuge des öffentlichen Verkehrs zu schaffen.The object of the invention is to provide a compact and simple design unlocking device for public transport vehicles.

Erfindungsgemäß wird die Aufgabe durch eine gattungsgemäße Entriegelungsvorrichtung gelöst, aufweisend:

  • eine mit einer ersten drehbaren Welle verbundene Umlenkwippe, die über ein Verbindungselement mit einem Entriegelungselement eines Schlosses verbunden ist, und einen abstehenden Mitnehmerbolzen aufweist,
  • einen auf der ersten Welle gelagerten und um die erste Welle drehbaren Betätigungshebel,
  • ein mit einer zweiten drehbaren Welle verbundenes Nockenrad, das mit der Umlenkwippe kämmt,
    wobei
  • ein Verdrehen des Nockenrades ein Verschwenken der Umlenkwippe und damit eine Bewegung des Verbindungselementes und ein Entriegeln des Schlosses bewirkt,
  • durch ein Verdrehen des Betätigungshebels der Betätigungshebel mit dem Mitnehmerbolzen in Kontakt kommt, den Mitnehmerbolzen und somit die Umlenkwippe bei weiterem Verdrehen mitnimmt, wodurch das Verbindungselement bewegt und das Schloss entriegelt wird.
According to the invention the object is achieved by a generic unlocking device, comprising:
  • a Umlenkwippe connected to a first rotatable shaft, which is connected via a connecting element with an unlocking element of a lock, and having a protruding driving pin,
  • a lever mounted on the first shaft and rotatable about the first shaft,
  • a cam wheel connected to a second rotatable shaft and meshing with the reversing shaft,
    in which
  • a rotation of the cam wheel causes a pivoting of the Umlenkwippe and thus a movement of the connecting element and unlocking the lock,
  • by rotation of the actuating lever of the actuating lever comes into contact with the driving pin, the driving pin and thus the Umlenkwippe entraining further rotation, whereby the connecting element moves and the lock is unlocked.

Die erfindungsgemäße Entriegelungsvorrichtung besteht also im Wesentlichen aus zwei miteinander kämmenden Elementen, nämlich der Umlenkwippe und dem Nockenrad. Beide können beispielsweise auf einer Grundplatte jeweils auf einer Welle gelagert sein. Das Nockenrad wird vorteilhafterweise von einem Motor, beispielsweise einem Elektro-Getriebemotor angetrieben.The unlocking device according to the invention thus consists essentially of two intermeshing elements, namely the Umlenkwippe and the cam wheel. Both can be mounted for example on a base plate each on a shaft. The cam wheel is advantageously driven by a motor, such as an electric geared motor.

Dadurch, dass die beiden Elemente miteinander kämmen, führt eine Rotation des Nockenrads dazu, dass die Umlenkwippe mitgenommen und ebenfalls in Drehung versetzt wird. Ein an der Umlenkwippe befestigter Bowdenzug wird durch die Drehbewegung der Umlenkwippe bewegt und entriegelt das Schloss, vorzugsweise ein Drehfallenschloss. Anstelle des Bowdenzugs kann auch ein anderes Verbindungselement eingesetzt werden, beispielsweise eine Schubstange, wobei dann die Drehung der Umlenkwippe die Schubstange schiebt und diese das Schloss entriegelt. Auch können durch das Verbindungselement mehrere Schlösser gleichzeitig entriegelt werden.Due to the fact that the two elements mesh with one another, a rotation of the cam wheel causes the reversing rocker to be entrained and likewise rotated. A Bowden cable attached to the Umlenkwippe is moved by the rotational movement of the Umlenkwippe and unlocks the lock, preferably a rotary latch lock. Instead of the Bowden cable, another connecting element can be used, for example a push rod, in which case the rotation of the Umlenkwippe pushes the push rod and this unlocks the lock. Also, several locks can be unlocked simultaneously by the connecting element.

In einer besonders vorteilhaften Ausführungsvariante ist eine Positionserfassungsvorrichtung vorgesehen, die die Position des Nockenrades erfasst. Diese kann dann über eine geeignete Elektronik an den Fahrer des Fahrzeugs übermittelt werden, so dass dieser stets über die aktuelle Position oder Stellung der Entriegelungsvorrichtung informiert ist.In a particularly advantageous embodiment, a position detection device is provided which detects the position of the cam wheel. This can then be transmitted via a suitable electronics to the driver of the vehicle, so that it is always informed about the current position or position of the unlocking device.

Das Nockenrad kann zwei einander diametral gegenüberliegende Nocken aufweisen, die mit einem an der Umlenkwippe angeordneten Hebelarm derart zusammenwirken, dass durch eine Drehung des Nockenrad um 180° der Hebelarm der Umlenkwippe einmal mitgenommen und somit die Umlenkwippe einmal betätigt wird. Ein Federelement bewirkt, dass die Umlenkwippe nach der Betätigung wieder in ihre Ausgangslage zurückbewegt wird.The cam wheel may have two diametrically opposed cams, which cooperate with a arranged on the Umlenkwippe lever arm such that once taken by rotation of the cam by 180 °, the lever arm of the Umlenkwippe and thus the Umlenkwippe is operated once. A spring element causes the Umlenkwippe is moved back to its original position after the operation.

Um eine möglichst geräusch- und verschleißarme Betätigung der Entriegelungsvorrichtung zu ermöglichen, weist der mit dem Nockenrad kämmende Hebelarm endseitig ein drehbar gelagertes Element auf, das bei Drehung des Nockenrades auf dem korrespondierenden Nocken abrollt.In order to enable the lowest possible and low-wear operation of the unlocking device, the meshing with the cam lever arm end has a rotatably mounted element which rolls on rotation of the cam wheel on the corresponding cam.

Um über die betriebsbedingten Öffnungsvorgänge hinaus eine Notentriegelung zu ermöglichen, ist auf der ersten Welle vorteilhafterweise weiterhin ein um die erste Welle drehbar gelagerter Betätigungshebel vorgesehen. Dieser kann beispielsweise oberhalb oder unterhalb der Umlenkwippe angeordnet sein. Zur Bewegung des Betätigungshebels ist dieser vorzugsweise mit einem manuell zu betätigenden Notrad verbunden. Bei Drehung des Notrads rotiert somit der Betätigungshebel, bis er über den Mitnehmerbolzen die Umlenkwippe mitnimmt und dadurch das Verbindungselement bzw. den Bowdenzug betätigt, der dann das Schloss freigibt.In order to enable an emergency release beyond the operational opening operations, an actuating lever rotatably mounted about the first shaft is advantageously also provided on the first shaft. This can be arranged for example above or below the Umlenkwippe. To move the actuating lever this is preferably connected to a manually operated emergency. Upon rotation of the temporary spare thus the actuating lever rotates until it takes over the Umlenkbolzen Umlenkwippe and thereby actuates the connecting element or the Bowden cable, which then releases the lock.

Vorteilhafterweise kann an dem Betätigungshebel ein weiteres Zug- und/oder Druckelement angelenkt sein, über das der Betätigungshebel ebenfalls drehbar ist. Somit ist die Notentriegelung zum einen über das Notrad, zum anderen über das weitere Zug- und/oder Druckelement möglich.Advantageously, a further pulling and / or pressure element can be articulated to the actuating lever, via which the actuating lever is also rotatable. Thus, the emergency release is possible on the one hand on the emergency, on the other hand on the other tensile and / or pressure element.

Eine weitere externe Notentriegelung, welche über den Bowdenzug die Umlenkwippe betätigt, besteht lediglich aus einer Welle und einem Betätigungshebel mit aufgesetztem Notrad.Another external emergency release, which actuates the Umlenkwippe on the Bowden, consists only of a shaft and an operating lever with attached emergency.

Auch das Notrad kann elektrisch antreibbar ausgeführt sein, denkbar ist auch eine Kombination aus manuellem und elektrischem Antrieb. Der Betätigungshebel und der Mitnehmerbolzen sind nur als erste Ausführungsbeispiele für die Kontaktierung und Auslösung der Notentriegelung zu verstehen, sie können auch durch andere gleichartig wirkende Elemente ersetzt werden.Also, the temporary spare wheel can be designed to be electrically driven, conceivable is also a combination of manual and electric drive. The actuating lever and the driving pins are to be understood only as first embodiments for contacting and triggering the emergency release, they can also be replaced by other similar-acting elements.

Der Betätigungshebel hat einen definierten Leerhub, muss also eine gewisse Strecke zurücklegen, ehe er den Mitnehmerbolzen kontaktiert. Dies ergibt sich daraus, dass der Hubweg des Bowdenzugs und damit die notwendige Rotation der Umlenkwippe zur Entriegelung des Schlosses in der Regel deutlich geringer sind, als die notwendige Rotation des Betätigungshebels bzw. Notrades, welches in einer vorteilhaften Ausführungsvariante mindestens 90° betragen muss.The operating lever has a defined idle stroke, so must cover a certain distance before he contacted the driving pin. This results from the fact that the stroke of the Bowden cable and thus the necessary rotation of the Umlenkwippe for unlocking the lock are usually much lower than the necessary rotation of the operating lever or emergency wheel, which must be at least 90 ° in an advantageous embodiment.

Auch der Betätigungshebel kann über ein Federelement, z.B. über Drehfedern, wieder in die Ausgangsstellung zurückbewegt werden.Also, the operating lever may be connected via a spring element, e.g. via torsion springs, be moved back to the starting position.

Zur Überwachung der Entriegelungsvorrichtung können Schaltelemente vorgesehen sein, die die Betätigung und/oder die Stellung der Notentriegelung detektieren.To monitor the unlocking switching elements may be provided which detect the operation and / or the position of the emergency release.

Um ein Betätigen der Notentriegelung während der Fahrt zu verhindern, kann es notwendig sein, die Notentriegelungseinrichtung zu blockieren. Hierzu wird im öffentlichen Nahverkehr vom Fahrzeug oftmals ein Signal während der Fahrt geliefert (3 km/h-Signal), welches in der Entriegelungsvorrichtung direkt oder über ein Steuergerät verarbeitet werden kann.In order to prevent actuation of the emergency release while driving, it may be necessary to block the emergency release device. For this purpose, in public transport from the vehicle often a signal while driving delivered (3 km / h signal), which can be processed in the unlocking directly or via a control unit.

In einer besonders vorteilhaften Ausführungsvariante ist eine elektrisch wirkende Blockierung auf der Grundplatte oder auf der Unterseite der Grundplatte vorgesehen. Durch die Anordnung im Bereich der Grundplatte baut die gesamte Entriegelungsvorrichtung klein und kompakt.In a particularly advantageous embodiment, an electrically acting blocking on the base plate or on the underside of the base plate is provided. The arrangement in the region of the base plate, the entire unlocking device is small and compact.

Ist die Blockierungseinrichtung auf der Unterseite der Grundplatte vorgesehen, weist die Grundplatte einen Schlitz auf, durch den sich der Mitnehmerbolzen erstreckt. Auf der Grundplattenunterseite ist ein Blockierungsarm drehbar gelagert, in den eine Kurvenbahn eingearbeitet ist, in der der Mitnehmerbolzen geführt ist. Bei jeder Bewegung der Umlenkwippe wird dadurch der Blockierungsarm mitgeführt.If the blocking device is provided on the underside of the base plate, the base plate has a slot through which the driving pin extends. On the base plate underside a blocking arm is rotatably mounted, in which a curved track is incorporated, in which the driving pin is guided. With each movement of the Umlenkwippe thereby the Blockierungsarm is carried.

Der Blockierungsarm weist weiterhin eine magnetisch wirkende Magnetfläche auf. Ist die Notentriegelung während der Fahrt unbetätigt, liegt die Magnetfläche des Blockierungsarms an einem ebenfalls an der Grundplatte angeordneten elektrischen Haftmagneten an. Ist der Haftmagnet bestromt, z.B. ausgelöst durch das 3 km/h-Signal, kann der Blockierungsarm und damit die Umlenkwippe nicht mehr bewegt werden. Durch Ausschalten der Bestromung des Haftmagneten wird die Blockierung aufgehoben.The blocking arm further has a magnetically acting magnetic surface. If the emergency release is inactivated while driving, the magnetic surface of the blocking arm is located at a likewise arranged on the base plate electric holding magnets on. If the magnet is energized, eg triggered by the 3 km / h signal, the blocking arm and thus the diverting rocker can no longer be moved. By switching off the energization of the magnet, the blocking is canceled.

Durch die Auswahl des Haftmagneten ist es möglich, die Blockierungskraft zu beeinflussen. Hierdurch kann beispielsweise ein wirksamer Vandalismusschutz sichergestellt oder auch eine Paniköffnung der Tür ermöglicht werden. Die Verwendung von Haftmagneten hat weiterhin den großen Vorteil, dass bereits bei geringer Leistungsaufnahme sehr hohe Haftkräfte erzeugbar sind.By selecting the magnet, it is possible to influence the blocking force. As a result, for example, an effective protection against vandalism can be ensured or even a panic opening of the door can be made possible. The use of magnetic clamps also has the great advantage that even at low power very high adhesive forces can be generated.

In eine weitere Führungsbahn des Blockierungsarms kann sich ein Führungsbolzen erstrecken, der ebenfalls fest mit der Grundplatte verbunden ist. Die Führungsbahn bewirkt eine Führung des Blockierungsarms und, je nach Länge der Führungsbahn, werden Endanschläge für den Führungsbolzen, und somit auch Endanschläge für die Umlenkwippe geschaffen.In another guideway of the blocking arm, a guide pin can extend, which is also firmly connected to the base plate. The guideway causes a leadership of Blockierungsarms and, depending on the length of the guideway, end stops for the guide pin, and thus also provided end stops for the Umlenkwippe.

In einer weiteren vorteilhaften Ausführungsvariante ist es alternativ möglich, die Notentriegelung pneumatisch zu blockieren. Ein Pneumatikzylinder ist hierzu ebenfalls mit der Grundplatte verbunden und sperrt je nach Betätigung die Bewegungsrichtung der Umlenkwippe. Der Pneumatikzylinder ist hierzu vorzugsweise mit einer Rückholfeder ausgebildet und wird über ein Ventil angesteuert, welches wiederum unmittelbar vom 3 km/h-Signal betätigt wird.In a further advantageous embodiment, it is alternatively possible to block the emergency release pneumatically. A pneumatic cylinder is also connected to the base plate and locks depending on the operation, the direction of movement of the Umlenkwippe. The pneumatic cylinder is for this purpose preferably formed with a return spring and is controlled by a valve, which in turn is operated directly from the 3 km / h signal.

Die Figuren 1 bis 4 verdeutlichen den Aufbau einer ersten erfindungsgemäßen Entriegelungsvorrichtung 20.The FIGS. 1 to 4 illustrate the structure of a first unlocking device 20 according to the invention.

Auf einer Grundplatte 3 sind ein Nockenrad 1 und eine Umlenkwippe 4 angeordnet, wobei die Umlenkwippe 4 auf einer ersten Welle 6 und das Nockenrad 1 auf einer zweiten Welle 7 drehbar gelagert sind.On a base plate 3, a cam wheel 1 and a Umlenkwippe 4 are arranged, wherein the Umlenkwippe 4 are rotatably mounted on a first shaft 6 and the cam 1 on a second shaft 7.

Das Nockenrad 1 wird im gezeigten Ausführungsbeispiel von einem Elektro-Getriebemotor 13, der auf der gegenüberliegenden Seite der Grundplatte 3 angeordnet ist, angetrieben. Eine Positionserfassungsvorrichtung zur Erfassung der Position des Nockenrades 1 ist durch einen Schalter 2 realisiert, der zueinander diametral gegenüberliegende Nocken 22 des Nockenrads 1 stirnseitig kontaktiert.The cam wheel 1 is driven in the embodiment shown by an electric geared motor 13 which is arranged on the opposite side of the base plate 3. A position detecting device for detecting the position of the cam wheel 1 is realized by a switch 2, the front diametrically opposed cam 22 of the cam wheel 1 contacted.

Das Nockenrad 1 kämmt mit der Umlenkwippe 4, insbesondere mit einem daran angeformten Hebelarm 24. Der Hebelarm 24 weist an seinem mit dem Nockenrad 1 kämmenden freien Ende eine drehbare Rolle 26 auf, die auf dem jeweiligen Nocken 22 des Nockenrads 1 abrollt.
An die Umlenkwippe 4 ist ein Verbindungselement 5 angelenkt, das bei einer Drehung der Umlenkwippe 4 gezogen und ein nicht gezeigtes Schloss betätigt bzw. entriegelt. Das Verbindungselement 5 ist vorzugsweise als Bowdenzug ausgeführt.The cam wheel 1 meshes with the deflection rocker 4, in particular with a lever arm 24 integrally formed thereon. The lever arm 24 has a rotatable roller 26 on its free end which meshes with the cam wheel 1, which rolls on the respective cam 22 of the cam wheel 1.
To the Umlenkwippe 4, a connecting element 5 is articulated, which is pulled at a rotation of the Umlenkwippe 4 and actuates a lock, not shown, or unlocked. The connecting element 5 is preferably designed as a Bowden cable.

Um eine Notentriegelung zu gewährleisten, ist auf der ersten Welle 6 ein Betätigungshebel 8 angeordnet, der um die erste Welle 6 drehbar ist. Die Umlenkwippe 4 bzw. der Hebelarm 24 weist einen in Seitenansicht gemäß Figur 4 aufrecht abstehenden Mitnehmerbolzen 11 auf, der bei Drehung des Betätigungshebels 8 von diesem kontaktiert und mitgenommen werden kann. Der Betätigungshebel 8 ist wiederum mit einem Notrad 12 fest verbunden und kann über dieses gedreht werden.To ensure an emergency release, an actuating lever 8 is arranged on the first shaft 6, which is rotatable about the first shaft 6. The Umlenkwippe 4 and the lever arm 24 has a side view in accordance FIG. 4 upright projecting driving pin 11, which can be contacted and taken on rotation of the operating lever 8 of this. The actuating lever 8 is in turn fixedly connected to a temporary spare wheel 12 and can be rotated about this.

Die Drehung des Betätigungshebels 8 ist auch über ein weiteres Zugelement 10 möglich, das ebenfalls am Betätigungshebel 8 angelenkt ist.The rotation of the actuating lever 8 is also possible via a further tension element 10, which is also articulated on the actuating lever 8.

Der Betätigungshebel 8 ist im gezeigten Ausführungsbeispiel als Teilscheibe ausgeführt, er kann aber auch als abstehender Hebel entsprechend dem Hebelarm 24 ausgeführt sein.The actuating lever 8 is executed in the embodiment shown as a partial disc, but it can also be designed as a projecting lever corresponding to the lever arm 24.

Figur 2 zeigt die Entriegelungsvorrichtung 20 in der Grundposition, in der die Notentriegelung nicht betätigt ist. FIG. 2 shows the unlocking device 20 in the basic position in which the emergency release is not actuated.

Figur 3 zeigt die erfindungsgemäße Entriegelungsvorrichtung 20 mit betätigter Notentriegelung. Es ist erkennbar, dass sich der Hebelarm 24 vom Nockenrad 1 wegbewegt hat, was durch die Kontaktierung des Mitnehmerbolzens 11 durch den Betätigungshebel 8 und eine anschließende weitere Drehung bewirkt wurde. Durch die Drehung der Umlenkwippe wird auch das Verbindungselement 5 bewegt und das nicht gezeigte Schloss entriegelt. Nicht gezeigte Federelemente können eine automatische Rückstellung der Umlenkwippe 4 und/oder des Betätigungshebels 8 bewirken. Hierzu eignen sich beispielsweise Drehfedern.
Aus den Figuren 2 und 3 ist weiterhin erkennbar, dass ein Leerhub des Betätigungshebels 8, also die Strecke, die der Betätigungshebel bis zum Kontakt mit dem Mitnehmerbolzen 11 zurücklegen muss, der mit etwa 90° deutlich größer ist, als der notwendige Hubweg des Verbindungselements 5 zur Entriegelung des Schlosses. Mit anderen Worten ist eine Drehung des Notrades 12 um etwa 90° notwendig, bevor die Notentriegelung ausgelöst wird, die Umlenkwippe 4 dagegen muss zur Entriegelung des Schlosses lediglich um weniger als 30° gedreht werden. FIG. 3 shows the unlocking device 20 according to the invention with actuated emergency release. It can be seen that the lever arm 24 has moved away from the cam wheel 1, which was caused by the contacting of the driving pin 11 by the actuating lever 8 and a subsequent further rotation. By the rotation of the Umlenkwippe the connecting element 5 is moved and the lock, not shown, unlocked. Not shown spring elements can cause an automatic return of the Umlenkwippe 4 and / or the actuating lever 8. For example, torsion springs are suitable for this purpose.
From the Figures 2 and 3 is still recognizable that a Leerhub of the actuating lever 8, ie the distance that the operating lever has to travel back to the contact with the driving pin 11, which is significantly greater with about 90 °, than the necessary stroke of the connecting element 5 for unlocking the lock. In other words, a rotation of the emergency wheel 12 by about 90 ° is necessary before the emergency release is triggered, the reversing rocker 4, however, must be rotated to unlock the lock only by less than 30 °.

Die Figuren 5 und 6 zeigen die Entriegelungsvorrichtung 20 von unten, also mit Sicht auf die dem Nockenrad 1 und der Umlenkwippe 4 gegenüberliegende Seite der Grundplatte 3. Der Mitnehmerbolzen 11 ist durch einen Schlitz in der Grundplatte 3 hindurchgeführt. Ein Blockierungsarm 14 ist über ein Lager 15 drehbar an der Grundplatte 3 gelagert. Der Blockierungsarm 14 weist eine Kurvenbahn 14b auf, in welcher der Mitnehmerbolzen 11 geführt ist. Bei jeder Bewegung der Umlenkwippe 4 wird dadurch der Blockierungsarm 14 mitgeführt. Ist die Notentriegelung unbetätigt, beispielsweise während der Fahrt, liegt eine in den Blockierungsarm 14 integrierte Magnetfläche 14a an einem ebenfalls an der Grundplatte 3 befestigten Haftmagneten 16 an. Wird dieser bestromt, kann der Blockierungsarm 14 und damit die Umlenkwippe 4 nicht mehr bewegt werden (vgl. Figur 5).The Figures 5 and 6 show the unlocking device 20 from below, so with a view of the cam wheel 1 and the Umlenkwippe 4 opposite side of the base plate 3. The driving pin 11 is passed through a slot in the base plate 3. A blocking arm 14 is rotatably mounted on the base plate 3 via a bearing 15. The blocking arm 14 has a curved path 14b, in which the driving pin 11 is guided. Each time the deflection rocker 4 moves, the blocking arm 14 is carried along. If the emergency release is unconfirmed, for example while driving, a magnetic surface 14a integrated in the blocking arm 14 rests against a holding magnet 16 likewise fastened to the base plate 3. If this is energized, the blocking arm 14 and thus the deflection rocker 4 can no longer be moved (cf. FIG. 5 ).

Wird dagegen die Magnetkraft aufgehoben, ist der Blockierungsarm 14 bewegbar und damit die Blockierung aufgehoben (vgl. Figur 6). Der Haftmagnet 16 wirkt somit als Fixierungsvorrichtung für den Blockierungsarm 14.On the other hand, if the magnetic force is removed, the blocking arm 14 is movable and thus the blocking is canceled (see. FIG. 6 ). The holding magnet 16 thus acts as a fixing device for the blocking arm 14.

Weiterhin ist vorteilhafterweise ein Bolzen 17 vorgesehen, der fest mit der Grundplatte 3 verbunden ist und sich in eine weitere Führungsbahn 14c des Blockierungsarms 14 erstreckt. Der Bolzen 17 und die Führungsbahn 14c wirken als Endanschläge und Führung für den Blockierungsarm 14 und somit auch als Endanschläge für die Umlenkwippe 4.Furthermore, a bolt 17 is advantageously provided which is fixedly connected to the base plate 3 and extends into a further guide track 14c of the blocking arm 14. The bolt 17 and the guide track 14c act as end stops and guide for the blocking arm 14 and thus also as end stops for the Umlenkwippe. 4

Figur 7 zeigt eine alternative Blockierungsvorrichtung für die erfindungsgemäße Entriegelungsvorrichtung 20. Ein ebenfalls auf der Grundplatte 3 angeordneter Pneumatikzylinder 18 ist derart angeordnet, dass er die Bewegung der Umlenkwippe 4 sperren kann. Vorteilhafterweise weist der Pneumatikzylinder eine Rückholfeder 19 auf und wird über ein nicht gezeigtes Ventil angesteuert, welches beispielsweise vom 3 km/h-Signal angesteuert wird. FIG. 7 shows an alternative blocking device for the unlocking device 20 according to the invention. A likewise arranged on the base plate 3 pneumatic cylinder 18 is arranged such that it can block the movement of the Umlenkwippe 4. Advantageously, the pneumatic cylinder has a return spring 19 and is controlled by a valve, not shown, which is driven for example by the 3 km / h signal.

Die Erfindung ist nicht auf die gezeigten Ausführungsbeispiele beschränkt, sondern erstreckt sich auch auf gleichwertige Abwandlungen der technischen Komponenten. The invention is not limited to the exemplary embodiments shown, but also extends to equivalent modifications of the technical components.
