Description

Die Erfindung bezieht sich auf eine Notbetätigungseinrichtung für grifflose Türverriegelungen, insbesondere für Schwenkschiebetüren von Fahrzeugen, bei denen eine Klinke am Türblatt mit einem türrahmenfesten Riegel zusammenwirkt, dem ein benachbarter, von einer steuerbaren Kraftquelle beaufschlagter Eintriegelungshebel zugeordnet ist. Solche Türverriegelungen werden meist mittels einer Druckknopfsteuerung geschaltet, wobei als Kraftquelle ein Magnet, ein hydraulischer oder pneumatischer Arbeitszylinder vorgesehen sein kann. Weiters ist eine Notbetätigungseinrichtung vorgesehen, die bei Ausfallen der Kraftquelle das Entriegeln der Tür von Hand aus ermöglicht. Hiebei besteht die Schwierigkeit, daß die Entriegelung auf die große Kraft der Kraftquelle eingestellt ist und dadurch die Notbetätigung einen erheblichen Kraftaufwand erfordert. Sobald hiefür ein Schlüssel vorgesehen ist, kann die erforderliche Kraft kaum hervorgerufen werden.The invention relates to an emergency actuation device for handle-free door locks, in particular for pivoting sliding doors of vehicles, in which a pawl on the door leaf interacts with a bolt which is fixed to the door frame and to which an adjacent locking lever acted upon by a controllable power source is assigned. Such door locks are mostly switched by means of a push button control, and a magnet, a hydraulic or pneumatic working cylinder can be provided as the power source. Furthermore, an emergency actuation device is provided which enables the door to be unlocked manually if the power source fails. Hiebei there is the difficulty that the release is set to the large force of the power source and thereby the emergency operation requires considerable effort. As soon as a key is provided for it, the required force can hardly be generated.

Die Erfindung bezweckt eine Notbetätigungseinrichtung zu schaffen, bei der die von Hand aufzubringende Kraft in eine mehrfach größere Entriegelungskraft übersetzt ist.The invention aims to provide an emergency actuation device in which the force to be applied by hand is translated into an unlocking force that is several times greater.

Erfindungsgemäß ist diese Aufgabe dadurch gelöst, daß ein Hebelsystem vorgesehen ist, das einerseits türrahmenfest angelenkt ist und anderseits mittels eines Verbindungselements, wie Bowdenzung, Verbindungsstange o.dgl., mit einem Betätigungsorgan, wie Nothandgriff, mittels Mehrkantschlüssel verschwenkbarem Hebel o.dgl., in Wirkverbindung steht, wobei einer der Hebel am Entriegelungshebel angreift und die Richtung der hier angreifenden Hebelkraft mit der Kraftrichtung des Verbindungselements einen, dem gewünschten Verhältnis dieser beiden Kräfte entsprechend großen Winkel einschließt.According to the invention this object is achieved in that a lever system is provided which is articulated on the one hand fixed to the door frame and on the other hand by means of a connecting element, such as bowdening, connecting rod or the like, with an actuating element, such as an emergency handle, pivotable lever or the like, using a polygonal key, in There is an operative connection, one of the levers acting on the unlocking lever and the direction of the lever force acting here including the force direction of the connecting element forming an angle which is large according to the desired ratio of these two forces.

Die Erfindung ist auf einige Ausgestaltungen dieser Notbetätigungseinrichtung gerichtet.The invention is directed to some configurations of this emergency actuation device.

In der Zeichnung ist der Gegenstand der Erfindung in drei beispielsweisen Ausführungsformen dargestellt. Es zeigen Fig. 1 eine Ansicht einer erfindungsgemäßen Türverriegelung, Fig. 2 einen Schnitt nach der Linie 11-11, die Fig. 3 und 4 zwei Ausführungsvarianten in Ansicht und Fig. 5 einen Schnitt nach der Linie V-V in Fig. 1.In the drawing, the subject matter of the invention is shown in three exemplary embodiments. 1 shows a view of a door lock according to the invention, FIG. 2 shows a section along the line 11-11, FIGS. 3 and 4 show two embodiment variants in view and FIG. 5 shows a section along the line V-V in FIG. 1.

In den Fig. 1 und 2 ist ein in seiner Gesamtheit mit 1 bezeichnetes Schloß dargestellt, das aus einem Rahmen 2 und einer Platte 3 besteht und mit seiner Grundseite 4 am Türrahmen 5 befestigt ist.1 and 2, a lock designated in its entirety with 1 is shown, which consists of a frame 2 and a plate 3 and is attached with its base 4 to the door frame 5.

In Fig. 2 ist das Türblatt mit 6 bezeichnet und in geschlossener Stellung dargestellt. Eine Zwischenstellung ist punktiert angedeutet. Es ist daraus die Richtung der seitlichen Verschiebung zu Beginn und am Ende der Öffnungsbewegung ersichtlich. Das Türblatt ist mit einer Klinke 7 versehen, die auch in Fig. 1 dargestellt ist. Sie ist um die Achse 8 am Türblatt schwenkbar gelagert und weist eine Doppelverzahnung 9 an ihrem freien Ende auf.In Fig. 2 the door leaf is designated 6 and shown in the closed position. An intermediate position is indicated by dotted lines. The direction of the lateral displacement at the beginning and at the end of the opening movement can be seen from this. The door leaf is provided with a pawl 7, which is also shown in Fig. 1. It is pivotally mounted on the door leaf about the axis 8 and has double teeth 9 at its free end.

Auf der Außenseite der Platte 3 ist einstellbar ein Riegel 10 angeschraubt, der mit der Klinke 7 zusammenwirkt. Zur Entriegelung ist ein Entriegelungshebel 11 vorgesehen, der um die Achse 12 - schwenkbar an der Platte 3 gelagert ist und unter der Wirkung einer Zugfeder 13 steht. Unterhalb des Entriegelungshebels 11 ist eine Kraftquelle 14 vorgesehen, welche auf einer Konsole 15, die am Rahmen 2 und an der Platte 3 angeschweißt ist, getragen wird. Im dargestellten Beispiel handelt es sich bei dieser Kraftquelle 14 um einen pneumatischen Arbeitszylinder, dessen Stempel 16 an einer bombierten Gegenfläche 17 angreift.On the outside of the plate 3, a bolt 10 is screwed, which interacts with the pawl 7. For unlocking, an unlocking lever 11 is provided which is pivotably mounted on the plate 3 about the axis 12 and is under the action of a tension spring 13. Below the unlocking lever 11, a power source 14 is provided, which is carried on a bracket 15 which is welded to the frame 2 and the plate 3. In the example shown, this power source 14 is a pneumatic working cylinder, the stamp 16 of which engages on a cambered counter surface 17.

An der Platte 3 ist ferner ein Zughebel 18 um eine Achse 19 schwenkbar gelagert und steht unter der Wirkung einer Zugfeder 20. Auf dem Zughebel 18 ist eine Rolle 21 drehbar gelagert, die auf der Seitenfläche 22 eines Plättchens 23 abrollen kann. Dieses Plättchen ist auf einem Fortsatz 24 des Entriegelungshebels 11 ein-und feststellbar. Der Zughebel 18 läuft in eine Führung 25 aus, in der ein Gleitstück 26 unverlierbar geführt ist und in Verbindung mit einem Bowdenzug 27 steht. Parallel dazu ist ein zweiter Bowdenzug und ein zweites Gleitstück vorgesehen, das in einer der gezeichneten Nut 28 gegenüberliegenden Nut gleiten kann. Der eine Bowdenzug führt zu einem Nothandgriff im Fahrzeuginneren und ist auch den Passagieren zugänglich. Der zweite Bowdenzug führt zu einem Schwenkhebel, der von außen mittels eines Mehrkantschlüssels verdreht werden kann.On the plate 3, a tension lever 18 is also pivotally mounted about an axis 19 and is under the action of a tension spring 20. On the tension lever 18, a roller 21 is rotatably mounted, which can roll on the side surface 22 of a plate 23. This plate can be engaged and locked on an extension 24 of the unlocking lever 11. The pull lever 18 ends in a guide 25, in which a slide 26 is captively guided and is connected to a Bowden cable 27. Parallel to this, a second Bowden cable and a second sliding piece are provided which can slide in a groove opposite the groove 28 shown. One Bowden cable leads to an emergency handle inside the vehicle and is also accessible to passengers. The second Bowden cable leads to a swivel lever that can be turned from the outside using a polygonal key.

Beim Schließen der Tür 6 wird der Entriegelungshebel 11 von der Klinke 7 nach unten gedrückt und dessen Verzahnung 9 fällt hinter dem Riegel 10 ein, wodurch die Tür in ihrer Schließlage gehalten wird. Die Entriegelung erfolgt durch Drucktasten, wodurch über elektromagnetische Ventile die Kraftquelle 14 gesteuert wird, und zwar drückt beim Öffnen der Stempel 16 den Entriegelungshebel 11 nach oben und nimmt hiebei die Klinke 7 mit, so daß dessen Verzahnung 9 außer Eingriff mit dem Riegel 10 kommt. Die Tür ist frei zum Öffnen.When the door 6 is closed, the unlocking lever 11 is pressed down by the pawl 7 and its toothing 9 engages behind the bolt 10, as a result of which the door is held in its closed position. The unlocking is carried out by push buttons, whereby the power source 14 is controlled via electromagnetic valves, that is, when the punch 16 is opened, pushes the unlocking lever 11 upwards and takes the pawl 7 with it, so that its teeth 9 come out of engagement with the bolt 10. The door is free to open.

Fällt die Steuerung der Kraftquelle 14 aus, so kann an jedem der Bowdenzüge eine hinreichende Kraft aufgebracht werden, die mittels des Lenkersystems ins Große übersetzt wird und daher eine Notentriegelung möglich ist. "Bei Betätigen eines - . Bowdenzuges schwenkt der Zughebel 18 im Uhrzeigersinn entgegen der Kraft der Feder 20 und die Rolle 21 rollt auf der Fläche 22 ab und verschwenkt somit den Entriegelungshebel 11 ebenfalls im Uhrzeigersinn. Dadurch kann die Entriegelung vorgenommen werden. Das Gleitstück des anderen Bowdenzuges bleibt an seiner Stelle und gleitet in der Nut 28 der Führung 25 nach vorne, während der Hebel 18 verschwenkt wird.If the control of the power source 14 fails, a sufficient force can be applied to each of the Bowden cables, which force is translated into large quantities by means of the steering system and an emergency release is therefore possible. "When a Bowden cable is actuated, the pull lever 18 pivots clockwise against the force of the spring 20 and the roller 21 rolls on the surface 22 and thus also pivots the unlocking lever 11 clockwise. The unlocking can thus be carried out Bowden cable remains in place and slides forward in the groove 28 of the guide 25 while the lever 18 is pivoted.

Nachdem die Rolle 21 nur Kräfte senkrecht zur Fläche 22 hervorrufen kann, schließt diese Kraftrichtung mit der Kraftrichtung des Bowdenzuges 27 einen Winkel von etwa 50° ein, und mit Rücksicht auf die Hebelwirkung der Hebeln 11 und 18 wird eine hinreichend große Kraft zum Öffnen der Verriegelung aufgebracht.Since the roller 21 can only produce forces perpendicular to the surface 22, this direction of force includes an angle of approximately 50 ° with the direction of force of the Bowden cable 27, and with regard to the lever action of the levers 11 and 18, a sufficiently large force is used to open the lock upset.

Die Offenstellung der Verriegelung kann optisch und akustisch angezeigt werden, wozu ein entsprechender Schalter 29 vorgesehen ist, dessen Schalthebel 30 auf die Fläche 31 des Entriegelungshebels 11 aufläuft.The open position of the lock can be indicated optically and acoustically, for which purpose a corresponding switch 29 is provided, the switch lever 30 of which runs onto the surface 31 of the unlocking lever 11.

Gemäß Fig. 3 besteht das Hebelsystem aus einem bei 32 an der Platte 3 angelenkten Hebel 33, der an seinem freien Ende mit einem zweiten Hebel 34 gelenkig verbunden ist, der einerseits mit der Führung 25 versehen ist und anderseits mit einem Stift 35 in ein Langloch 36 des Entriegelungshebels 11 eingreift. Die übrige Anordnung stimmt mit der in Fig. 1 dargestellten überein. Zufolge des Langloches 36 kann der Entriegelungshebel 11 von der Kraftquelle 14 verschwenkt werden, ohne daß das Hebelsystem in Bewegung gesetzt wird. Wird am Bowdenzug 27 gezogen, so drückt der Stift 35 den Entriegelungshebel 11 nach unten und verschwenkt ihn im Uhrzeigersinn. Hier schließt die Kraftrichtung des Hebels 34 mit der Kraftrichtung des Bowdenzuges 27 einen Winkel von etwa 70° ein, so daß eine mehrfache Kraftübersetzung vorliegt.3, the lever system consists of a lever 33 articulated at 32 on the plate 3, which is articulated at its free end to a second lever 34, which is provided on the one hand with the guide 25 and on the other hand with a pin 35 in an elongated hole 36 of the unlocking lever 11 engages. The rest of the arrangement corresponds to that shown in FIG. 1. Due to the elongated hole 36, the unlocking lever 11 can be pivoted by the power source 14 without the lever system being set in motion. If the Bowden cable 27 is pulled, the pin 35 presses the unlocking lever 11 downwards and pivots it clockwise. Here, the force direction of the lever 34 includes an angle of approximately 70 ° with the force direction of the Bowden cable 27, so that there is a multiple force transmission.

Ein kniehebelartiges Lenkersystem ist in Fig. 4 dargestellt. Ein Lenker 37 ist oben am Rahmen 2 des Schlosses angelenkt und ist gelenkig mit einem Hebel 38 verbunden, der an einem Ende die Führung 25 trägt und am anderen Ende einen Stift 39 aufweist, der in einem Langloch 40 des Entriegelungshebels 11 eingreift. Es ist bekannt, daß bei solchen Kniehebelanordnungen eine sehr große Kraftübersetzung erreicht werden kann.A toggle-type handlebar system is shown in Fig. 4. A link 37 is articulated on the frame 2 of the lock and is articulated to a lever 38 which carries the guide 25 at one end and has a pin 39 at the other end which engages in an elongated hole 40 in the unlocking lever 11. It is known that a very large power transmission ratio can be achieved with such toggle lever arrangements.

Die Funktion des Hebelsystems nach Fig. 3 und 4 wirkt in gleicher Weise zur Entriegelung wie das im Zusammenhang mit Fig. 1 beschriebene System.The function of the lever system according to FIGS. 3 and 4 acts in the same way for unlocking as the system described in connection with FIG. 1.

Es kann erwünscht sein, daß eine absolute Sperre der Tür vorgenommen werden soll, weshalb in Fig. 5 eine entsprechende Lösung hiefür angegeben wird. Die Einrichtung befindet sich im unteren Teil des Schlosses 1 und besteht aus einer Konsole 51, die mittels Schrauben 52 an der Platte 3 des Schlosses 1 angeschraubt ist. An ihr ist eine 'Welle 53 gelagert, die an ihrer Unterseite einen Arm 54 und an ihrem oberen Ende eine Kurvenscheibe 55 trägt. Eine Drehfeder 56 versucht die Welle 53 in Fig. 5 entgegen dem Uhrzeigersinn zu verdrehen.It may be desirable to lock the door completely, which is why a corresponding solution is given in FIG. The device is located in the lower part of the lock 1 and consists of a bracket 51 which is screwed onto the plate 3 of the lock 1 by means of screws 52. A shaft 53 is mounted on it, which has an arm 54 on its underside and a cam 55 at its upper end. A torsion spring 56 tries to turn the shaft 53 counterclockwise in FIG. 5.

Der Arm 54 reicht in die Bewegungsbahn eines Sperrstiftes 57, der in der Tür 6 verschiebbar gelagert ist. Dieser Sperrstift 57 wirkt mit einer Anlage 58 zusammen, welche bei vorgeschobenem Sperrstift ein Öffnen der Tür verhindert. Beim Vorschieben der Stange 57 verdrängt seine Spitze den Arm 54, so daß über die Welle 53 die Kurvenscheibe 55 verschwenkt und ein Schalter 59 geschaltet wird. Dieser zeigt an, daß die Sperre wirksam ist.The arm 54 extends into the path of movement of a locking pin 57 which is slidably mounted in the door 6. This locking pin 57 interacts with a system 58 which prevents the door from opening when the locking pin is advanced. When the rod 57 is advanced, its tip displaces the arm 54, so that the cam plate 55 is pivoted via the shaft 53 and a switch 59 is switched. This indicates that the lock is in effect.

Der Sperrstift 57 kann in beliebiger Weise angetrieben sein.The locking pin 57 can be driven in any way.

Die Einrichtung nach Fig. 5 stellt eine Türsperre für eine grifflose Türverriegelung, insbesondere für Schwenkschiebetüren von Fahrzeugen dar und ist dadurch charakterisiert, daß im Türblatt 6 eine längsverschiebbare Sperrstange 57 vorgesehen ist, die an einem Anschlag 58 entlanggleitet und daß weiters ein Schwenkhebel 53,54,55 türrahmenfest gelagert ist, dessen einer Arm 54 in die Bewegungsbahn der Sperrstange ragt und dessen anderer Arm 55 zur Betätigung eines Schalters 59 ausgebildet ist.5 is a door lock for a handle-less door lock, in particular for pivoting sliding doors of vehicles and is characterized in that a longitudinally displaceable locking rod 57 is provided in the door leaf 6, which slides along a stop 58 and that furthermore a pivot lever 53, 54 , 55 is mounted fixed to the door frame, one arm 54 of which protrudes into the movement path of the locking rod and the other arm 55 is designed to actuate a switch 59.

Diese Türsperre eignet sich auch für andere Türgattungen.This door lock is also suitable for other door types.
