Description

Die Erfindung betrifft eine Schließvorrichtung mit einem aus einem Unterteil und einem metallischen Oberteil bestehenden Mantelgehäuse, welches ein aus Metall bestehendes Zylindergehäuse umfaßt, in dem ein Zylinderkern drehbar gelagert ist, der über Zuhaltungen mit dem Zylindergehäuse verriegelbar ist.The invention relates to a locking device with a lower part and one metallic shell existing casing, which is an existing metal Cylinder housing includes, in which a cylinder core is rotatably mounted, the tumblers can be locked with the cylinder housing.

Eine derartige Schließvorrichtung ist beispielsweise aus der DE 38 27 418 A1 bekannt. Dabei bestehen das Mantelgehäuse, das Zylindergehäuse und der Zylinderkern mit den Zuhaltungen üblicherweise aus einer Metall-Legierung (Zinkdruckguß-Legierung). Die bekannte Schließvorrichtung ist daher relativ stabil und weist eine gute Diebstahlsicherheit auf.Such a locking device is known for example from DE 38 27 418 A1. There are the casing, the cylinder housing and the cylinder core with the Tumblers usually made of a metal alloy (zinc die-cast alloy). The Known locking device is therefore relatively stable and has good theft protection on.

Als nachteilig hat es sich allerdings erwiesen, daß die aneinander anliegenden Metallteile bei längerem Nichtbetätigen der Schließvorrichtung durch Kontaktkorrosion oder Schmutz bzw. durch verharztes Fett festsitzen, so daß sich die Schließvorrichtung nur schwer oder überhaupt nicht mehr durch den entsprechenden Schlüssel betätigen läßt. Besonders bei neueren Fahrzeugen, bei denen die Fahrzeugtüren mittels Fernbedienung geöffnet und verschlossen werden, tritt daher das Problem auf, daß im Falle einer Notbetätigung mit dem Schlüssel die Schließvorrichtung nicht mehr funktionsfähig ist.It has proven to be disadvantageous, however, that the metal parts lying against one another if the locking device is not operated for a long time due to contact corrosion or dirt or stuck with resinized fat, so that the locking device is difficult or can no longer be operated by the corresponding key. Especially at newer vehicles in which the vehicle doors are opened and closed by remote control are, therefore, the problem arises that in the event of an emergency operation with the Key the locking device is no longer functional.

Es sind bereits Schließvorrichtungen mit einem Zylinderkern aus Kunststoff bekannt, bei denen die aus Metall bestehenden Zuhaltungen ohne Fett montiert werden. Allerdings sind derartige Schließvorrichtungen nicht diebstahlsicher und können leicht durch einen unbefugten Dritten aufgebrochen werden. Sie werden daher überwiegend lediglich zur Sicherung von Handschuhkästen und Tankverschlüssen eingesetzt.Locking devices with a plastic cylinder core are already known for to which the tumblers made of metal are mounted without grease. However such locking devices are not theft-proof and can easily be accessed by an unauthorized person Third be broken up. They are therefore mainly used only for security purposes of glove boxes and tank caps.

Der Erfindung liegt die Aufgabe zugrunde, eine diebstahlsichere Schließvorrichtung zu offenbaren, deren bestimmungsgemäße Verwendung auch nach längerem Nichtgebrauch noch sichergestellt ist, und die daher insbesondere für Fahrzeuge geeignet ist, deren Türen in erster Linie durch Betätigung einer Fernbedienung geöffnet und verschlossen werden.The invention has for its object to an anti-theft locking device disclose their intended use even after long periods of non-use is still ensured, and which is therefore particularly suitable for vehicles whose doors can be opened and closed primarily by operating a remote control.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the subclaims.

Die Erfindung beruht im wesentlichen auf dem Gedanken, eine Schließvorrichtung mit einem Zylinderkern aus Kunststoff zu verwenden, der mit einem Zylinderkopf aus Metall drehfest verbunden ist. Der Zylinderkopf weist dabei auf seiner dem Zylinderkern zugewandten Seite einen Kragen auf, welcher in einer Ausnehmung zwischen dem Gehäuseoberteil und einem an dem Gehäuseunterteil anliegenden L-förmigen Ringkragen des Zylinderkerns angeordnet ist. Dadurch kann der Zylinderkopf bei an der Fahrzeugtür montierter Schließvorrichtung durch unbefugte Dritte nicht entfernt werden und der mit dem Zylinderkopf verbundene und aus Kunststoff bestehende Zylinderkern kann weder gewaltsam aus dem Zylindergehäuse herausgezogen noch eingeschlagen werden.The invention is essentially based on the idea of having a locking device to use a plastic cylinder core with a metal cylinder head is rotatably connected. The cylinder head faces the cylinder core Side on a collar, which in a recess between the upper housing part and an L-shaped ring collar of the cylinder core which bears against the lower housing part is arranged. This allows the cylinder head to be mounted on the vehicle door Locking device cannot be removed by unauthorized third parties and that with the Cylinder head connected and made of plastic cylinder core can neither be violent pulled out of the cylinder housing can still be hammered in.

Um eine schnelle und genaue Montage der Schließvorrichtung zu erreichen, hat es sich als vorteilhaft erwiesen, wenn die drehfeste Verbindung zwischen dem Zylinderkern und dem Zylinderkopf über eine Formschlußverbindung und die axiale Fixierung der beiden Teile über eine Klipsverbindung erfolgt.In order to achieve a quick and accurate assembly of the locking device, it has proven to be proven to be advantageous if the non-rotatable connection between the cylinder core and the Cylinder head via a positive connection and the axial fixation of the two parts via a clip connection.

Bei einer bevorzugten Ausführungsform der Erfindung ist der axiale Schenkel des L-förmigen Ringkragens des Zylinderkerns umfangseitig in vorgegebenen Abständen als Anlagenocken ausgebildet und weist in diesen Bereichen jeweils eine Länge auf, die derart gewählt ist, daß zwischen dem Kragen des Zylinderkopfes und dem Oberteil des Mantelgehäuses eine spaltförmige Öffnung verbleibt. Dadurch wird sichergestellt, daß auch über den Rand des Zylinderkerns ein Kontakt zwischen dem Zylinderkopf und dem Oberteil des Mantelgehäuses vermieden wird.In a preferred embodiment of the invention, the axial leg of the L-shaped Ring collar of the cylinder core on the circumference at predetermined intervals as System cam formed and in each of these areas has a length that such is chosen that between the collar of the cylinder head and the upper part of the casing a gap-shaped opening remains. This will ensure that over the edge of the cylinder core a contact between the cylinder head and the top of the Jacket housing is avoided.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus den folgenden anhand von Figuren erläuterten Ausführungsbeispielen. Es zeigen:

  • Fig. 1 den Längsschnitt durch einen Teil einer erfindungsgemäßen Schließvorrichtung;
  • Fig.2 einen Schnitt entlang der in Fig. 1 mit II-II bezeichneten Linie und
  • Fig.3 einen Schnitt entlang der in Fig.1 mit III-III bezeichneten Linie.
    • Further details and advantages of the invention result from the following exemplary embodiments explained with reference to figures. Show it:
  • Figure 1 shows the longitudinal section through part of a locking device according to the invention.
  • 2 shows a section along the line labeled II-II in FIG. 1 and
  • 3 shows a section along the line labeled III-III in FIG.

    • In Fig.1 ist mit 1 eine Schließvorrichtung für eine nicht dargestellte Kraftfahrzeugtür bezeichnet. Die Schließvorrichtung 1 umfaßt ein z.B. aus einem Zinkdruckguß bestehendes Mantelgehäuse 2, das sich im wesentlichen aus einem zylinderförmigen Unterteil 3 und einem darüber formschlüssig angeordneten Oberteil 4 zusammensetzt. Dabei sind Unter- und Oberteil beispielsweise über eine Bajonettverbindung oder über Stifte miteinander verbunden. An dem Unterteil 3 liegt innenseitig ein aus Metall bestehendes Zylindergehäuse 5 an, in dem ein aus Kunststoff bestehender Zylinderkern 6 drehbar gelagert ist, der über nur schematisch angedeutete Zuhaltungen 7 mit dem Zylindergehäuse 5 verriegelbar ist.In Figure 1, 1 denotes a locking device for a motor vehicle door, not shown. The locking device 1 comprises e.g. consisting of a die-cast zinc Sheath housing 2, which consists essentially of a cylindrical lower part 3 and an upper part 4 arranged above it form-fitting. Here are and the upper part, for example via a bayonet connection or via pins connected. On the inside of the lower part 3 there is a cylinder housing made of metal 5, in which an existing plastic cylinder core 6 is rotatably supported by only schematically indicated tumblers 7 can be locked with the cylinder housing 5.

    Auf der der Schlüsseleinführseite 8 zugewandten Stirnseite 9 ist an dem Zylinderkern 6 erfindungsgemäß ein Zylinderkopf 10 aus Metall (z.B. Zinkdruckguß) befestigt. Über dem Zylinderkopf 10 ist zusätzlich z.B. aus ästhetischen Gründen- eine Kappe 11, beispielsweise aus Stahl oder Kunststoff, angeordnet.On the end face 9 facing the key insertion side 8 is on the cylinder core 6 according to the invention, a cylinder head 10 made of metal (e.g. die-cast zinc) is attached. About that Cylinder head 10 is additionally e.g. for aesthetic reasons - a cap 11, for example made of steel or plastic.

    Der Zylinderkopf 10 weist auf seiner dem Zylinderkern 6 zugewandten Seite einen Kragen 12 auf, der in einer Ausnehmung 13 angeordnet ist. Die Ausnehmung 13 wird dabei einerseits durch einen umlaufenden L-förmig ausgebildeten Ringkragen 14 des sich an dem Unterteil 3 und dem frontseitigen Ende 15 des Zylindergehäuses 5 abstützenden Zylinderkerns 6 und andererseits durch das Oberteil 4 gebildet, so daß der Zylinderkopf 10 -und damit auch der Zylinderkern 6- gegen Herausziehen gesichert sind. The cylinder head 10 has a collar on its side facing the cylinder core 6 12, which is arranged in a recess 13. The recess 13 is on the one hand by a circumferential L-shaped annular collar 14 which is attached to the Lower part 3 and the front end 15 of the cylinder housing 5 supporting cylinder core 6 and on the other hand formed by the upper part 4, so that the cylinder head 10 -and so that the cylinder core 6 is secured against being pulled out.

    In der Ausnehmung 13 befindet sich außerdem ein Dichtring 16, der das Eindringen von Feuchtigkeit in das Innere der Schließvorrichtung 1 verhindern soll. Eventuell trotzdem in das Innere der Schließvorrichtung 1 gelangende Feuchtigkeit kann über die in Fig. 3 mit 17 bezeichnete Öffnung nach außen abfließen.In the recess 13 there is also a sealing ring 16, which prevents the penetration of Prevent moisture in the interior of the locking device 1. Possibly in anyway the inside of the closing device 1 can reach the moisture level in FIG. 3 with 17 Drain the designated opening to the outside.

    Der Zylinderkopf 10 und der Zylinderkern 6 sind zur axialen Fixierung durch eine Klipsverbindung miteinander verbunden. Hierzu befinden sich an dem äußeren Umfang 18 des Zylinderkerns 6 drei gleichmäßig über den Umfang verteilt angeordnete nasenförmige Vorsprünge 19 (Fig.1), die in entsprechende Ausnehmungen 20 des Zylinderkopfes 10 eingreifen (zur besseren Darstellung der Rastverbindung wurde in Fig.1 eine der drei Rastnasen 19 und die zugeordnete Ausnehmung 20 in die Zeichnungsebene geschwenkt wiedergegeben).The cylinder head 10 and the cylinder core 6 are for axial fixation by a clip connection connected with each other. For this purpose, are located on the outer circumference 18 of the Cylinder core 6 three nose-shaped arranged evenly distributed over the circumference Protrusions 19 (FIG. 1) which fit into corresponding recesses 20 in the cylinder head 10 intervene (one of the three Lugs 19 and the associated recess 20 pivoted into the plane of the drawing reproduced).

    Zur drehfesten Verbindung zwischen dem Zylinderkern 6 und dem Zylinderkopf 10 weist der Zylinderkopf zwei gegenüberliegende Nocken 24 auf, die in entsprechende Längsnuten 25 des Zylinderkerns 6 formschlüssig eingreifen.For the rotationally fixed connection between the cylinder core 6 and the cylinder head 10 has the cylinder head has two opposing cams 24 which engage in corresponding longitudinal grooves 25 of the cylinder core 6 engage positively.

    Um zu verhindern, daß zwischen dem Zylinderkopf 10 und dem Oberteil 4 des Mantelgehäuses 2 ein Kontakt erfolgt, ist der axiale Schenkel 21 des L-förmigen Ringkragens 14 des Zylinderkerns 6 umfangseitig in vorgegebenen Abständen als Anlagenocken 22 ausgebildet (Fig.3) und weist in diesen Bereichen jeweils eine Länge auf, die derart gewählt ist, daß zwischen dem Kragen 12 des Zylinderkopfes 10 und dem Oberteil 4 des Mantelgehäuses 2 eine spaltförmige Öffnung 23 von z.B. 01, bis 0,2 mm verbleibt (Fig. 1).To prevent that between the cylinder head 10 and the upper part 4 of the casing 2 contact occurs, the axial leg 21 of the L-shaped ring collar 14 of the cylinder core 6 is formed on the circumference at predetermined intervals as system cams 22 (Fig. 3) and has a length in each of these areas, which is selected in such a way that between the collar 12 of the cylinder head 10 and the upper part 4 of the casing 2 a slit-shaped opening 23 of e.g. 01 to 0.2 mm remains (Fig. 1).

    Auf der dem Zylinderkopf 10 zugewandten Seite des Zylinderkerns 6 ist mit diesem ein an sich bekannter Staubverschluß 26 über eine Klipsverbindung verbunden.On the side facing the cylinder head 10 of the cylinder core 6 is one with this known dust lock 26 connected via a clip connection.

    Die Erfindung ist selbstverständlich nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. So kann beispielsweise zur Verbindung zwischen Zylinderkern und Zylinderkopf letzterer statt mit Nocken auch mit einer umlaufenden Runde versehen sein, die in eine entsprechende Ausnehmung des Zylinderkems eingreift. The invention is of course not based on the embodiment described above limited. For example, the connection between the cylinder core and The cylinder head of the latter can also be provided with a circumferential round instead of cams, which engages in a corresponding recess in the cylinder core.
