Description

Die Erfindung bezieht sich auf eine Vorrichtung mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a device with the features of the preamble of patent claim 1.

Eine gattungsgemäße Kupplungsvorrichtung für Seil- oder Bowdenzüge ist bekannt (DE-PS 29 05 958). Sie ermöglicht manuelles Trennen der Seelen und der Umhüllungen zweier Seilzug-Teilstücke bei Überprüfungs- und Inspektionsarbeiten und ebenfalls manuelles Wiederzusammenfügen der Seilzug-Seelen und -Umhüllungen nach Abschluß dieser Arbeiten.A generic coupling device for cable or Bowden cables is known (DE-PS 29 05 958). It enables manual separation of the core and the cladding of two cable sections during inspection and inspection work and also manual re-assembly of the cable core and cladding after completion of this work.

Ferner ist es bekannt (DE-OS 21 16 448), bei einer Kraftfahrzeug-Diebstahlsicherung einen zur Motorhaubenschloß-Fernentriegelung dienenden Seilzug mittels eines durch Fremdkraft ferngesteuert zu betätigenden Stellantriebes zu blockieren, d.h. so festzulegen, daß sich der Seilzug nicht mehr zum Entriegeln der Motorhaube bewegen läßt.Furthermore, it is known (DE-OS 21 16 448), in a motor vehicle anti-theft device, to block a cable pull remote unlocking cable by means of an externally operated actuator to be blocked, that is to say so that the cable can no longer unlock the hood can move.

Auch aus der GB-PS 1 434 505 ist bereits eine Blockiervorrichtung für den Entriegelungshebel und den Entriegelungsseilzug einer Motor- bzw. Gepäckraumhauben-Entriegelung bekannt, bei welcher aber ein eigener über das Zündschloß mechanisch festlegbarer Sicherungsseilzug mit dem Entriegelungshebel durch Form-Eingriff zweier korrespondierender und mit dem Entriegelungshebel zusammen verschiebbarer Formteile gekuppelt ist. Bei Durchtrennung des festgelegten Sicherungsseilzugs wird das mit diesem fest verbundene erste Formteil durch eine Schraubenfeder relativ zu dem mit dem Entriegelungshebel verbundenen zweiten Formteil verschoben, wobei letzteres über eine Gleitkurve des ersten Formteils mit einer Stufe des beide Formteile umhüllenden und mittelbar führenden Gehäuses in Form-Eingriff gebracht wird. Durch diesen neuerlichen, anderseitigen Form-Eingriff soll wiederum eine Verschiebung des Entriegelungshebels und -seilzuges in Entriegelungsrichtung verhindert werden. Der eigentliche Entriegelungsseilzug wird gemäß der genannten GB-PS weder direkt blockiert noch vom Entriegelungshebel oder in sich selbst entkuppelt.From GB-PS 1 434 505 a blocking device for the unlocking lever and the unlocking cable of an engine or luggage compartment cover unlocking is already known, but in which a separate safety cable, which can be mechanically fixed by means of the ignition lock, with the unlocking lever by the form engagement of two corresponding and is coupled with the unlocking lever together movable moldings. When the fixed safety cable is severed, the first molded part which is fixedly connected to it is displaced by a helical spring relative to the second molded part connected to the unlocking lever, the latter being in shape engagement via a sliding curve of the first molded part with a step of the housing which envelops and molds the two molded parts brought. This new, different-sided shape intervention in turn is intended to prevent displacement of the unlocking lever and cable in the unlocking direction. According to the aforementioned GB-PS, the actual unlocking cable is neither directly blocked nor uncoupled from the unlocking lever or in itself.

Der übliche Motorhauben-Entriegelungshebel ist vor allem in zwar mit verriegelten Türen, aber offenem Verdeck abgestellten Cabriolet-Fahrzeugen leicht zugänglich. Mit den genannten und weiteren, rein mechanisch einzulegenden (DE-OSen 23 14 957, 26 35 505) Seilzug-Blockiereinrichtungen ist es nicht auszuschließen, daß Unbefugte durch Gewaltanwendung die Blockierung des Seilzuges überwinden und sich Zugang zum Motorraum verschaffen, um dort z.B. die Bordnetzbatterie abzuklemmen und dadurch eine eventuell vorhandene Diebstahl-Warnanlage auszuschalten.The usual bonnet release lever is easily accessible, especially in convertible vehicles parked with the doors locked but the top down. With the mentioned and other, purely mechanically inserted (DE-OSes 23 14 957, 26 35 505) cable-blocking devices, it cannot be ruled out that unauthorized persons can overcome the blocking of the cable by force and gain access to the engine compartment, e.g. disconnect the on-board electrical system battery and thereby switch off any anti-theft alarm system.

Schließlich ist noch eine Vorrichtung bekannt, die es erlaubt, den Verschiebeweg einer durchgehenden Seilzugseele in ihrer Umhüllung auf einstellbare Strecken zu begrenzen (US 3,744,339). Sie dient insbesondere dazu, den Öffnungswinkel einer über die Seilzugseele betätigten Drosselklappe eines Fahrzeugmotor-Vergasers für einen bestimmten Benutzerkreis einzuschränken. Zu diesem Zweck ist auf den Seilzug ein Kloben aufgeschraubt, dessen Bewegung längs der Seilrichtung durch ein in derselben Richtung verstellbares Anschlagmittel begrenzbar ist.Finally, a device is known which allows the displacement path of a continuous cable core in its sheathing to be limited to adjustable distances (US Pat. No. 3,744,339). It is used in particular to restrict the opening angle of a throttle valve of a vehicle engine carburetor, which is actuated via the cable core, for a specific group of users. For this purpose, a block is screwed onto the cable, the movement of which along the cable direction can be limited by a stop means adjustable in the same direction.

Die Erfindung hat die Aufgabe, die Betätigung einer gattungsgemäßen Vorrichtung zu vereinfachen, um insbesondere ihre vorteilhafte Verwendbarkeit in einer Kraftfahrzeug-Diebstahlsicherung der genannten Art zu fördern.The invention has the task of simplifying the operation of a generic device, in particular to promote its advantageous usability in a motor vehicle anti-theft device of the type mentioned.

Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Patentanspruchs 1 erfindungsgemäß gelöst.This object is achieved according to the invention with the characterizing features of patent claim 1.

Die Merkmale der Unteransprüche kennzeichnen vorteilhafte Weiterbildungen der erfindungsgemäßen Vorrichtung.The features of the subclaims characterize advantageous developments of the device according to the invention.

Wenn gemäß der Erfindung zwei Seilzug-Teilstücke ferngesteuert entkuppelt werden können, vereinfacht dies die Betätigung beliebiger Kupplungen für Seilzug-Teilstücke. Im Rahmen einer zentral steuerbaren Diebstahlsicherung für Kraftfahrzeuge hat die Unterbrechung des Kraftflusses im Seilzug z.B. einer Motorhauben-Fernentriegelung gegenüber einer Blockierung des Seilzugs den Vorteil, daß sich eine Gewaltanwendung am Entriegelungshebel nicht auf das Haubenschloß oder auf den Seilzug selbst auswirken kann.If, according to the invention, two cable sections can be decoupled by remote control, this simplifies the actuation of any couplings for cable sections. In the context of a centrally controllable anti-theft device for motor vehicles, the interruption of the power flow in the cable, e.g. a remote bonnet release, has the advantage over blocking the cable that the use of force on the release lever cannot affect the hood lock or the cable itself.

Zwar ist es bekannt (DE-OS 35 00 550), im Zusammenhang mit einer Türverriegelung zwei Schwenkhebel unter anderem mittels eines Stellelementes in und außer Kupplungsüberdeckung zu bringen, wobei an einem der Schwenkhebel ein Seilzug zur Schloßbetätigung angelenkt ist.It is known (DE-OS 35 00 550), in connection with a door lock, to bring two swivel levers into and out of clutch cover, inter alia by means of an actuating element, a cable pull being articulated on one of the swivel levers for actuating the lock.

Für die Anordnung in der Bewegungsachse zweier Seilzug-Seelen ist diese Schwenkhebel-Einrichtung im Gegensatz zu der gattungsgemäßen Seilzug-Kupplungsvorrichtung nicht geeignet.In contrast to the cable pull coupling device of the generic type, this swivel lever device is not suitable for the arrangement in the movement axis of two cable pull cores.

Ein Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung zum Kuppeln bzw. Entkuppeln zweier Seilzug-Teilstücke ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of a device according to the invention for coupling or uncoupling two cable sections is shown in the drawing and will be described in more detail below.

Die stark schematisierte Schnittzeichnung zeigt zwei Seilzug-Seelen 1 und 2, die von einander gegenüberliegenden Kopfseiten in ein Gehäuse 3 eingeführt sind. Die Seele 1 ist beispielsweise mit einem Motorhauben-Entriegelungshebel 1′ im Fahrgastraum eines Kraftfahrzeuges verbunden, während die Seele 2 beispielsweise mit einem nicht gezeigten Motorhaubenschloß-Öffner im Motorraum des Kraftfahrzeugs verbunden sein kann. Beide Seelen 1 und 2 sind außerhalb des im wesentlichen zylindrischen Gehäuses 3 in der üblichen Weise von Seilzugführungen 4 längsverschiebbar umhüllt.The highly schematic sectional drawing shows two cable pulleys 1 and 2, which are inserted into a housing 3 from opposite sides of the head. The core 1 is connected, for example, to a hood release lever 1 'in the passenger compartment of a motor vehicle, while the core 2 can be connected, for example, to a hood lock opener, not shown, in the motor compartment of the motor vehicle. Both souls 1 and 2 are enveloped longitudinally displaceably outside the essentially cylindrical housing 3 in the usual manner by cable pull guides 4.

Im Inneren des Gehäuses 3, das an von außen unzugänglicher Stelle im Fahrzeug befestigt ist, ist mit der Seele 2 ein erstes Formteil 5 verbunden. Dieses besteht aus einer im Gehäuse 3 in Bewegungsrichtung der Seilzug-Seelen 1 und 2 verschiebbar geführten Schiebemuffe 5.1 und einer über ein Gelenk 5.2 in der Schiebemuffe angelenkten Klinke 5.3.A first molded part 5 is connected to the core 2 in the interior of the housing 3, which is fastened to the vehicle in an inaccessible place. This consists of a sliding sleeve 5.1 guided in the housing 3 in the direction of movement of the cable pulleys 1 and 2 and a pawl 5.3 articulated in the sliding sleeve via a joint 5.2.

Die Klinke weist ferner noch einen Betätigungshebel 5.4 und eine an diesen angeformte Gleitfläche 5.5 auf.The pawl also has an actuating lever 5.4 and a sliding surface 5.5 formed thereon.

Mit der Seele 1 ist ein zweites Formteil 6 verbunden. Dieses weist ein mit der Klinke 5.3 korrespondierendes, in deren durchgezogen gezeichneter Stellung im Form-Eingriff stehendes Widerlager 6.1 auf und ist innerhalb der Schiebemuffe 5.1 verschiebbar geführt.
Das zweite Formteil 6 wird von einer Schraubendruckfeder 7, die sich in zur Seele 1 koaxialer Anordnung zwischen einer Gehäuse-Kopfseite und dem Formteil 6 abstützt, in die Schiebemuffe 5.1 hinein vorgespannt. Diese wird ferner durch die Kraft der Schraubendruckfeder 7 gegen einen Anschlag 3.1 des Gehäuses 3 gedrückt. In dieser definierten Ruhelage der beiden Formteile 5 und 6 ist die Klinke 5.3 gegenüber dem Widerlager 6.1 freigängig.A second molded part 6 is connected to the core 1. This has an abutment 6.1 corresponding to the pawl 5.3, in its solid-drawn position in the form engagement, and is displaceably guided within the sliding sleeve 5.1.
The second molded part 6 is biased into the sliding sleeve 5.1 by a helical compression spring 7, which is supported in a coaxial arrangement with the core 1 between a housing head side and the molded part 6. This is also pressed by the force of the helical compression spring 7 against a stop 3.1 of the housing 3. In this defined rest position of the two molded parts 5 and 6, the pawl 5.3 can move freely with respect to the abutment 6.1.

Im Gehäuse 3 ist ferner noch ein pneumatisches Stellelement 8 vorgesehen, dessen Membrankolben 8.1 mit einem als Stößel ausgebildeten Stellglied 8.2 durch wechselweise Über- bzw. Unterdruckbeaufschlagung-z.B. durch eine mittels Schlüssels steuerbare Bidruckpumpe - über einen Anschlußstutzen 8.3 in zwei stabile Endlagen - durchgezogen bzw. gestrichelt dargestellt - verbracht werden kann.In the housing 3 there is also a pneumatic actuating element 8, the diaphragm piston 8.1 of which, with an actuator 8.2 designed as a tappet, by alternately applying overpressure or vacuum, e.g. by means of a bi-pressure pump which can be controlled by means of a key - via a connecting piece 8.3 in two stable end positions - shown in full lines or in broken lines.

Das gegenüber der Membrankolben-Arbeitskammer abgedichtet in das Gehäuse 3 eingeführte Stellglied 8.2 steht mit der Gleitfläche 5.5 des Klinken-Betätigungshebels 5.4 in Wirkverbindung, wenn die beiden Formteile 5 und 6 in ihrer Ruhelage stehen. Eine Schraubendruckfeder 9 spannt zum einen die Klinke 5.3 gegen das Widerlager 6.1 und zum anderen die Gleitfläche 5.5 gegen das Stellglied 8.2 vor.The actuator 8.2, which is inserted into the housing 3 in a sealed manner with respect to the diaphragm piston working chamber, is operatively connected to the sliding surface 5.5 of the pawl actuating lever 5.4 when the two molded parts 5 and 6 are in their rest position. A helical compression spring 9 firstly biases the pawl 5.3 against the abutment 6.1 and secondly the sliding surface 5.5 against the actuator 8.2.

In der durchgezogen gezeichneten Stellung von Klinke 5.3 und Stellelement 8 ist eine Übertragung von Zugkräften im Kraftfluß
Hebel 1′ - Seele 1 - Formteil 6 / Widerlager 6.1 - Klinke 5.3 / Schiebemuffe 5.1 - Seele 2 möglich.In the solid position of pawl 5.3 and 8 is a transmission of tensile forces in the power flow
Lever 1 ′ - core 1 - molded part 6 / abutment 6.1 - pawl 5.3 / sliding sleeve 5.1 - core 2 possible.

In der gestrichelt gezeichneten Stellung von Klinke 5.3 und Stellelement 8 ist der Kraftfluß zwischen dem Widerlager 6.1 und der Klinke 5.3 unterbrochen, da die Klinke durch das Stellglied 8.2 über die Gleitfläche 5.5 bzw. den Betätigungshebel 5.4 angehoben und der Form-Eingriff beider Formteile aufgehoben ist.
Wird jetzt am Hebel 1′ gezogen, so wird sich lediglich das zweite Formteil 6 aus der Schiebemuffe 5.1 heraus gegen die rückstellende Schraubendruckfeder 7 bewegen, um nach Loslassen des Hebels 1′ in die gezeichnete Stellung zurückzukehren.
Der dargestellte Membrankolben 8.1 hat eine einer Übertotpunktfeder ähnliche elastische Charakteristik und hält die angehobene Klinke 5.3 auch ohne Dauerdruckbeaufschlagung in ihrer Stellung.In the position of the pawl 5.3 and the actuating element 8 shown in broken lines, the flow of force between the abutment 6.1 and the pawl 5.3 is interrupted because the pawl is raised by the actuator 8.2 over the sliding surface 5.5 or the actuating lever 5.4 and the form engagement of both molded parts is eliminated .
Is now pulled on the lever 1 ', only the second molded part 6 will move out of the sliding sleeve 5.1 against the resetting helical compression spring 7 to return to the drawn position after releasing the lever 1'.
The diaphragm piston 8.1 shown has an elastic characteristic similar to an over-center spring and holds the raised pawl 5.3 in its position even without permanent pressurization.

Nicht dargestellt ist eine einfach realisierbare Variante der Vorrichtung, in welcher das angehobene Stellglied 8.2 ferner noch eine z.B. mit einer Lasche an das erste Formteil 5 angeformte Bohrung durchdringt, so daß dieses zusätzlich zu der beschriebenen Kraftflußunterbrechung auch noch formschlüssig festgelegt wird.Not shown is an easily implementable variant of the device, in which the raised actuator 8.2 also penetrates a bore, for example formed on the first molded part 5 with a tab, so that in addition to the described power flow interruption it is also positively fixed.

Im Rahmen einer rein elektrisch gesteuerten zentralen Diebstahlsicherung kann das Stellelement auch mit einem Elektromagnet-Spulenantrieb ausgeführt werden. Dabei sollte dann aber das Stellglied unter Einwirkung einer Übertotpunktfeder stehen, damit dessen Endlagen jeweils festgelegt sind.As part of a purely electrically controlled central anti-theft device, the control element can also be designed with an electromagnetic coil drive. The actuator should then be under the action of an over-center spring so that its end positions are fixed.
