Description

Schließzylinder für insbesondere an Fahrzeugen vollziehbare Funktionen Lock cylinder for executable especially on vehicles functions
Die Erfindung richtet sich auf einen Schließzylinder der im Oberbegriff des Anspruches 1 angegebenen Art.The invention is directed to a lock cylinder specified in the preamble of claim 1 Art.
Ein wichtiges Anwendungsgebiet derartiger Schließzylinder ist ihre Verwendung an Türen oder Klappen eines Fahrzeugs. Die in diesem Fall anfallenden Funktionen sind das Sichern und Entsichern der Türen bzw. Klappen. Damit soll unbefugten Personen der Zugang zum Fahrzeug versperrt sein. Berechtigte Personen verfügen aber über einen dem Schließzylinder zugeordneten Schlüssel, der in einen Schlüsselkanal des Zylinderkerns eingesteckt wird und dadurch die federbelasteten Zuhaltungen in den Zylinderkern einordnet. Dann kann der Zylinderkern mittels des Schlüssels aus einer Nulllage in verschiedene Arbeitslagen überführt werden. Der Gehäuse-Oberteil und - Unterteil kapseln den Zylinderkern und alle übrigen Bauteile im Gehäuseinneren ein. Am einen Ende der miteinander verbundenen Gehäuseteile befindet sich der Schlüsselkanal für den Schlüssel zugänglich, während am anderen Ende ein Mitnehmer drehgelagert ist, der über eine Verbindungsstange eine Drehung des Zylinderkerns an die hinter dem Schließzylinder liegenden Funktionsteile im Fahrzeug weitergibt.An important application of such lock cylinders is their use on doors or flaps of a vehicle. The functions required in this case are the securing and unlocking of the doors or flaps. This should prevent access to the vehicle by unauthorized persons. Authorized persons, however, have a key associated with the lock cylinder, which is inserted into a keyway of the cylinder core and thereby arranges the spring-loaded tumblers into the cylinder core. Then the cylinder core can be transferred by means of the key from a zero position to different working positions. The housing upper part and lower part encapsulate the cylinder core and all other components inside the housing. At one end of the interconnected housing parts of the keyway for the key is accessible, while at the other end a driver is rotatably mounted, which passes on a connecting rod rotation of the cylinder core to the lying behind the lock cylinder functional parts in the vehicle.
Bei dem bekannten Schließzylinder der im Oberbegriff des Anspruches 1 angegebenen Art müssen die beiden Gehäuseteile mit den von ihnen aufgenommenen Bauteilen miteinander verstiftet werden. Die Entfernung des Spiralspannstifts ist ein mühsamer Vorgang wenn es darauf ankommt, die beiden Gehäuseteile voneinander zu trennen, um z.B. einen defekten Bauteil zu ersetzen. Außerdem müssen am Gehäuse Angriffsstellen für die Befestigungsmittel vorgesehen sein, mit denen das Gehäuse an der Karosserie des Fahrzeugs fixiert werden kann. Das ist zeit- und platzaufwendig.In the known lock cylinder specified in the preamble of claim 1, the two housing parts must be pinned together with the components taken by them. The removal of the spiral tension pin is a tedious process when it comes to separating the two housing parts from each other, for example, to replace a defective component. In addition, must on Housing attack sites be provided for the fastening means with which the housing can be fixed to the body of the vehicle. This is time consuming and space consuming.
Der Erfindung liegt die Aufgabe zugrunde, einen Schließzylinder der im Oberbegriff des Anspruches 1 genannten Art zu entwickeln, der die vorerwähnten Nachteile vermeidet. Dies wird durch die im Anspruch 1 angegebenen Maßnahmen erreicht, denen folgende besondere Bedeutung zukommt.The invention has for its object to develop a lock cylinder referred to in the preamble of claim 1 species, which avoids the aforementioned disadvantages. This is achieved by the measures specified in claim 1, which have the following special significance.
Bei der Erfindung haben die Befestigungsmittel für das Gehäuse an der Karosserie eine Doppelfunktion. Die erste, übliche Funktion besteht darin, den Schließzylinder an der Karosserie zu befestigen. Die zweite Funktion besteht aber darin, die Befestigungsmittel zugleich als Verbindungsmittel für die Festlegung des Gehäuse- Oberteils am Gehäuse-Unterteil zu nutzen. Damit genügen ein einziges Mittel und eine einzige Handhabung dieses Befestigungsmittels, um gleich mehrere Funktionen am Schließzylinder zu erfüllen. So wird Platz und Montagezeit eingespart. Das eventuelle Trennen der beiden Gehäuseteile ist zugleich sehr einfach, weil dann nur noch das Befestigungsmittel gelöst werden braucht. Dann ist nicht nur der Schließzylinder von der Karosserie getrennt, sondern auch das Gehäuse ist in seine beiden Teile zerlegbar. Auf diese Weise erhält man Zugang zu den im Gehäuseinneren eingekapselten Bauteilen.In the invention, the fastening means for the housing on the body have a dual function. The first, common function is to attach the lock cylinder to the body. The second function, however, is to use the fastening means at the same time as a connection means for fixing the housing upper part to the housing lower part. Thus, a single means and a single handling of this fastener are sufficient to fulfill several functions on the lock cylinder. This saves space and assembly time. The eventual separation of the two housing parts is at the same time very simple, because then only the fastener needs to be solved. Then not only the lock cylinder is separated from the body, but also the housing can be dismantled into its two parts. In this way one gains access to the encapsulated inside the housing components.
Weitere Maßnahmen und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, der nachfolgenden Beschreibung und den Zeichnungen. In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt. Es zeigen:Further measures and advantages of the invention will become apparent from the dependent claims, the following description and the drawings. In the drawing, the invention is shown in one embodiment. Show it:

Wie am besten aus Fig. 1 zu ersehen ist, besteht das Gehäuse 10 des Schließzylinders aus zwei Gehäuseteilen 1 1 , 12, deren Aussehen aus den perspektivischen Ansichten von Fig. 3a bis 4b zu entnehmen ist. Zwecks besserer Unterscheidung soll der dem Benutzer zugekehrte Gehäuseteil 1 1 mit „Unterteil" und der Gehäuseteil 12 mit „Oberteil" bezeichnet werden. Die beiden Gehäuseteile 1 1 , 12 kapseln eine Vielzahl von Bauteilen ein, die im montierten Zustand eine aus Fig. 1 ersichtliche vormontierte Baueinheit 15 bilden.As can be seen best from Fig. 1, the housing 10 of the lock cylinder consists of two housing parts 1 1, 12, the appearance of which can be seen from the perspective views of Fig. 3a to 4b. For a better distinction of the user facing housing part 1 1 is to be referred to "lower part" and the housing part 12 with "shell". The two housing parts 1 1, 12 encapsulate a plurality of components, which form a pre-assembled unit 15 apparent from FIG. 1 in the mounted state.
Zu diesen Baueinheiten im Inneren des Gehäuses 10 gehört vor allem ein Zylinderkern 20, der im Inneren einer Freilaufhülse 21 drehgelagert ist. Die Freilaufhülse 21 ruht normalerweise im Gehäuse 10. Der Zylinderkern 20 besitzt einen axialen Schlüsselkanal 22, der von mehreren Kammern 23 durchquert wird. Die Kammern 23 dienen zur Aufnahme von federbelasteten Zuhaltungen, deren nicht näher erkennbare Enden in mindestens einer axialen Nut der Freilaufhülse 21 eintreten. Dann ist der Zylinderkern 20 drehgesichert.To these units inside the housing 10 is especially a cylinder core 20 which is rotatably mounted inside a freewheel sleeve 21. The freewheel sleeve 21 normally rests in the housing 10. The cylinder core 20 has an axial keyway 22 which is traversed by a plurality of chambers 23. The chambers 23 serve to receive spring-loaded tumblers whose ends, which are not closer to one another, enter into at least one axial groove of the freewheel sleeve 21. Then the cylinder core 20 is secured against rotation.
Zur Freigabe der Drehung des Zylinderkerns 20 muss ein zugehöriger, nicht näher gezeigter Schlüssel im Sinne des Pfeils 24 in den Schlüsselkanal 22 eingesteckt werden. Der Schlüssel ordnet dann die Zuhaltungen auf den Querschnitt des Zylinderkerns 20 bündig ein. Dann greifen die Zuhaltungs-Enden nicht mehr in die Nut der Freilaufhülse 21 ein und der Zylinderkern 20 ist mittels des eingesteckten Schlüssels drehbar. Bei der Schlüsseldrehung gelangt das Drehmoment von einem Ausgang 25 des Zylinderkerns 20 über eine mehrere Bauteile umfassende Freilaufeinrichtung 26 auf einen Mitnehmer 27, der sich am inneren Ausgang 13 befindet. Eine Impulsfeder 28, die bestrebt ist den Mitnehmer 27 in einer definierten Nulllage zu halten, wirkt sich im Normalfall auch auf den Zylinderkern 20 aus. Über die Freilaufeinrichtung 26 wird im Normalfall, wenn die Freilaufhülse 21 ruht, auch der Zylinderkern 20 in dieser Nulllage gehalten.To release the rotation of the cylinder core 20 an associated, not shown in detail key in the direction of arrow 24 must be inserted into the keyway 22. The key then arranges the tumblers on the cross section of the cylinder core 20 flush. Then the tumbler ends no longer engage in the groove of the freewheel sleeve 21 and the cylinder core 20 is rotatable by means of the inserted key. When turning the key, the torque passes from an output 25 of the cylinder core 20 via a multi-component freewheel device 26 to a driver 27, which is located at the inner output 13. A pulse spring 28, which endeavors to keep the driver 27 in a defined zero position, in the normal case also has an effect on the cylinder core 20. About the freewheel device 26 is in the normal case, when the freewheel sleeve 21 rests, and the cylinder core 20 is held in this zero position.
Am äußeren Ausgang 14 des Gehäuses 10 ist dem Zylinderkern 20 stirnseitig eine gepanzerte Frontplatte 29 vorgeschaltet und unter Zwischenschaltung einer Elastomerscheibe 19 über Zapfen und Aufnahmen drehfest mit dem Zylinderkern 20 verbunden. Die Frontplatte 29 bestimmt die Einstecköffnung für den Schlüssel und ist gemäß dem Schlüsselquerschnitt gestaltet. Die Elastomerscheibe 19 hat Dichtfunktionen und dient zugleich als Schlagabsorber für im Sinne des Einsteckpfeils 24 ausgeübte, Einbruchszwecken dienende gewaltsame Schläge.At the outer output 14 of the housing 10, the cylinder core 20 frontally an armored front plate 29 is connected upstream and rotatably connected with the interposition of an elastomeric disk 19 via pins and recordings with the cylinder core 20. The front panel 29 determines the insertion opening for the key and is designed according to the key cross-section. The elastomeric disk 19 has sealing functions and at the same time serves as a shock absorber for violent impacts acting in the direction of the insertion arrow 24 and serving for burglary purposes.
Wie am besten aus den Detailansichten von Fig. 4a, 4b zu ersehen ist, ist der bereichsweise hülsenartig gestaltete Gehäuse-Oberteil 12 mit einem Lappen 16 versehen, in welchem sich ein Durchbruch 17 befindet. Der Lappen 16 verläuft, wie aus Fig. 1 zu erkennen ist, im zusammengebauten Zustand, geneigt zur strichpunktiert angedeuteten Achse 18 des Schließzylinders und damit des Zylinderkerns 20.As best seen in the detail views of Fig. 4a, 4b, the partially sleeve-like designed housing upper part 12 is provided with a tab 16 in which an opening 17 is located. The tab 16 runs, as can be seen from Fig. 1, in the assembled state, inclined to the dash-dotted lines indicated axis 18 of the lock cylinder and thus of the cylinder core 20th
Das Aussehen des Gehäuse-Oberteil 12 ergibt sich aus Fig. 3a und 3b. Wie auch aus dem Schnitt in Fig. 1 zu entnehmen ist, besitzt der Oberteil 12 einen seitlichen Gehäuseansatz 38 mit einer Aussparung 39, deren Bodenbereich einen Gegenlappen 36 bildet. Der Gehäuseansatz 38 ist mit einer Gewindeaufnahme 37 versehen.The appearance of the housing upper part 12 results from FIGS. 3a and 3b. As can also be seen from the section in FIG. 1, the upper part 12 has a lateral housing extension 38 with a recess 39, the bottom region of which forms a counter-flap 36. The housing extension 38 is provided with a threaded receptacle 37.
Beim Zusammenbau der Baueinheit 15 von Fig. 1 können die beiden Gehäuseteile 1 1 , 12 durch nicht näher gezeigte Rastmittel und Gegenrastmittel für einen vorläufigen Zusammenhalt sorgen. Ein solcher Zusammenhalt ergibt sich vor allem aber dann, wenn wie Fig. 1 verdeutlicht, der Lappen vom Gehäuse-Unterteil 12 in die Ausnehmung 39 vom Gehäuseansatz 38 des Gehäuse-Unterteils 1 1 eingreift. Die endgültige Verbindung zwischen den beiden Gehäuseteilen 1 1 , 12 erfolgt im vorliegenden Fall durch Befestigungsmittel 30, die den Schließzylinder an der Karosserie 33 fixieren. Das soll anhand der Fig. 5 näher erläutert werden.When assembling the assembly 15 of Fig. 1, the two housing parts 1 1, 12 provide by not shown detent means and counter-locking means for a provisional cohesion. However, such a cohesion arises above all when, as FIG. 1 illustrates, the tab of the lower housing part 12 engages in the recess 39 from the housing extension 38 of the housing lower part 11. The final connection between the two housing parts 1 1, 12 takes place in the present case by fastening means 30 which fix the lock cylinder on the body 33. This will be explained in more detail with reference to FIG. 5.
In Fig. 5 ist ein Teilstück einer Karosserie 33 eines Fahrzeugs gezeigt, wie z.B. die Heckklappe eines Fahrzeugs, die mit dem Schließzylinder versehen werden soll. Das Befestigungsmittel besteht aus einer Schraube 30. Die Karosserie 33 besitzt eine definierte Befestigungsstelle 34 für den Schließzylinder. Dort ist ein Loch 35 für die Schraube 30 vorgesehen. Im Befestigungsfall durchsetzt der Schaft der Schraube 30 das Loch 35 und den Lappen 16 im Gehäuse-Oberteil 12, während das Gewindestück 32 der Schraube in die bereits erwähnte Gewindeaufnahme 37 vom Ansatz 38 eingreift. Der Kopf 31 der Schraube 30 stützt sich dabei an der Oberseite der Karosserie-Befestigungsstelle 34 ab. Im Befestigungsfall von Fig. 5 verläuft die strichpunktiert eingezeichnete Achse 41 der Schraube 30 im spitzen Winkel 42 zur Achse 18 des Zylinderkerns 20.In Fig. 5, a portion of a body 33 of a vehicle is shown, e.g. the tailgate of a vehicle to be provided with the lock cylinder. The fastening means consists of a screw 30. The body 33 has a defined attachment point 34 for the lock cylinder. There, a hole 35 is provided for the screw 30. In the fastening case, the shank of the screw 30 passes through the hole 35 and the tab 16 in the housing upper part 12, while the threaded part 32 of the screw engages in the already mentioned threaded receptacle 37 from the projection 38. The head 31 of the screw 30 is supported on the top of the body attachment point 34. In the case of attachment of FIG. 5, the dash-dotted line 41 of the screw 30 extends at an acute angle 42 to the axis 18 of the cylinder core 20.
Im Befestigungsfall von Fig. 5 ist der Mitnehmer 27 des Schließzylinders über eine Drehverbindung 40 mit jenen Aggregaten im Fahrzeug verbunden, welche bei Drehbetätigung des Schließzylinders 20 die gewünschten Funktionen im Fahrzeug ausüben sollen. Im vorliegenden Fall soll die Drehverbindung 40 den Mitnehmer mit einem Schloss in der Heckklappe des Fahrzeugs verbinden. Dieses Schloss ist zwischen einer Sicherungsstellung und einer Entsicherungsstellung umsteuerbar. Es versteht sich, dass mittels des Mitnehmers auch beliebige andere Funktionen im Fahrzeug betätigt werden könnten.In the mounting case of Fig. 5, the driver 27 of the lock cylinder is connected via a rotary joint 40 with those units in the vehicle, which should exercise the desired functions in the vehicle during rotational actuation of the lock cylinder 20. In the present case, the rotary joint 40 is to connect the driver with a lock in the tailgate of the vehicle. This lock is reversible between a backup position and a release position. It is understood that by means of the driver any other functions could be operated in the vehicle.
Bei einer gewaltsamen Drehung des Zylinderkerns 20 mittels Einbruchswerkzeugen durch unberechtigte Personen bleibt der Zylinderkern 20 über seine erwähnten endseitig herausragenden Zuhaltungen mit der Freilaufhülse 21 in Eingriff. Dann wird eine Rast zwischen der Freilaufhülse 21 und dem Gehäuse 10 gelöst. Dann dreht sich der Zylinderkern 20 zusammen mit der Freilaufhülse 21 im Gehäuseinneren. Bei der gewaltsamen Drehung entkuppelt die Freilaufeinrichtung 26 den Mitnehmer 27 gegenüber dem Zylinderkern- Ausgang 25. Trotz der gewaltsamen Drehungen über das Einbruchswerkzeug bleibt daher der Mitnehmer 27 und damit auch die sich anschließende Drehverbindung 40 in Ruhe. Eine Funktion im Fahrzeug wird dann nicht ausgeführt. In a violent rotation of the cylinder core 20 by burglary tools by unauthorized persons of the cylinder core 20 remains above its mentioned outstanding outstanding tumblers with the freewheel sleeve 21 in engagement. Then, a detent between the freewheel sleeve 21 and the housing 10 is released. Then, the cylinder core 20 rotates together with the freewheel sleeve 21 inside the housing. In the violent rotation, the freewheel device 26 disengages the driver 27 against the cylinder core output 25. Despite the violent rotations about the burglary tool therefore remains the driver 27 and thus also the subsequent rotary joint 40 at rest. A function in the vehicle will not be executed.
