Description

Die Erfindung betrifft einen Schließzylinder mit Stiftzuhaltungen, einem Zylindergehäuse, einem Zylinderkern, der in einer Bohrung des Zylindergehäuses drehbar gelagert ist, um mehreren Paaren Gehäusestifte und Kernstifte, die durch Federkraft zu einem Schlüsselkanal zurückgeholt werden, der axial in den genannten Zylinderkern eingearbeitet ist, einem codierten Schlüssel, der in genanntem Schlüsseikanal gleitet und Einschnitte umfaßt, die jeweils mit einem der genannten Paare zusammenwirken, um es gegen die Wirkung der genannten Federmittel so zu verschieben, daß die Trennungsebene zwischen jedem Kernstift und jedem Gehäusestift eines Paares die Mantellinie des genannten Zylinderkerns berührt.The invention relates to a locking cylinder with tumblers, a cylinder housing, a cylinder core, which is rotatably mounted in a bore in the cylinder housing, to a plurality of pairs of housing pins and core pins, which are returned by spring force to a key channel, which is axially incorporated in said cylinder core coded key that slides in said key channel and includes cuts that each cooperate with one of said pairs to move it against the action of said spring means so that the plane of separation between each core pin and each housing pin of a pair touches the surface line of said cylinder core .

Solche Schließzylinder sind schon sehr lange u. a. aus der FR-A 7 918 918 - bekannt. Bei der Entwicklung mehr oder weniger automatisierter Massenfertigungen weisen die bekannten Schließzylinder den Nachteil auf, daß die Kombination, bestimmt durch die Stiftpaare, im allgemeinen schon zu Beginn der Fertigung eines Schlosses mit einem solchen Schließzylinder vorgegeben wird, so daß die automatische Fertigung sehr kompliziert und kostenaufwendig ist. Zudem wird dieses Problem vergrößert, wenn eine Mehrzahl von Schließzylindern der gleichen Kombination angefertigt werden muß, die eine Kollektion bildet. Dies ist der Fall besonders in der Automobilindustrie, wenn es erwünscht ist, daß ein einziger Schlüssel zu den Schließzylindern der Türen, des Lenkschlosses, des Tankverschlusses, des Handschuhfachs und des Kofferraums paßt.Such locking cylinders have been around for a very long time. a. from FR-A 7 918 918 - known. In the development of more or less automated mass production, the known locking cylinders have the disadvantage that the combination, determined by the pairs of pins, is generally specified at the beginning of the production of a lock with such a locking cylinder, so that the automatic production is very complicated and costly is. In addition, this problem is exacerbated when a plurality of lock cylinders have to be made of the same combination that forms a collection. This is particularly the case in the automotive industry when it is desired that a single key fit the lock cylinders of the doors, the steering lock, the fuel filler cap, the glove box and the trunk.

Zur Lösung dieses Problems wird in der FR-A 7 918 918 vorgeschlagen, die Gehäuse- und Kernstifte sowie deren Rückholfedern in einer Kassette vorzumontieren, die aus zwei in bezug zueinander gleitenden Teilen besteht. Diese Kassette, die die Kombination des Schließzylinders umfaßt, wird am Ende der Montage an Ort und Stelle gebracht und die beiden Teile der Gehäusestifte werden in ihre entsprechenden Bohrungen des Zylindergehäuses eingeführt.To solve this problem it is proposed in FR-A 7 918 918 to preassemble the housing and core pins and their return springs in a cassette which consists of two parts which slide with respect to one another. This cassette, which comprises the combination of the lock cylinder, is brought into place at the end of the assembly and the two parts of the housing pins are inserted into their corresponding bores in the cylinder housing.

Dieser bekannte vormontierte Schließzylinder, der einen deutlichen Vorteil gegenüber herkömmlichen Schließzylindern aufweist, ist aber nicht frei von verschiedenen Nachteilen. Zunächst einmal ist die Herstellung der Kassette wegen ihrer kleinen Abmessungen und der Anzahl der in ihr enthaltenen Bauteile recht heikel und erfordert eine hohe Präzision. Darüber hinaus ist, wie in den meisten Schließzylindern mit Stiftzuhaltungen. die Axiallänge, die der Zahl der Stiftpaare entspricht, die in Abhängigkeit von der Zahl der gewünschten verschiedenen Kombinationen verwendet wird, relativ groß.This known preassembled locking cylinder, which has a clear advantage over conventional locking cylinders, is not free from various disadvantages. First of all, the production of the cassette is quite delicate because of its small dimensions and the number of components it contains and requires a high degree of precision. In addition, like in most locking cylinders with pin tumblers. the axial length, which corresponds to the number of pin pairs used depending on the number of different combinations desired, is relatively large.

Ziel der Erfindung ist es, einen Schließzylinder mit Stiftzuhaltungen der beschriebenen Art zu erhalten, der eine Vormontage mit einfachen, sicheren und wirtschaftlichen Mitteln ermöglicht und dabei die Verwendung einer kurzen Axiallänge gestattet.The aim of the invention is to obtain a locking cylinder with tumblers of the type described, which enables preassembly with simple, safe and economical means and thereby allows the use of a short axial length.

Zu diesem Zweck ist der erfindungsgemäße Schließzylinder dadurch gekennzeichnet, daß die Paare aus Gehäusestiften und .Kernstiften sowie deren Federmittel jeweils in einer Radialbohrung des Zylindergehäuses vormontiert sind, wobei die genannten Radialbohrungen winkelig um die Achse des Schließzylinders in mindestens einer Diametralebene angeordnet und an ihrem inneren Ende durch einen beim Einstecken des Zylinderkerns entfernbaren Anschlag verschlossen sind, wobei der genannte Schließzylinder Axialgesperremittel aufweist, die mit Anschlagmittel des Gehäuses zur Anlage bringbar sind.For this purpose, the locking cylinder according to the invention is characterized in that the pairs of housing pins and core pins and their spring means are each pre-assembled in a radial bore of the cylinder housing, the radial bores mentioned being arranged at an angle around the axis of the locking cylinder in at least one diametral plane and at their inner end are closed by a stop which can be removed when the cylinder core is inserted, said locking cylinder having axial locking means which can be brought into abutment by means of the housing stop means.

Beim erfindungsgemäßen Schließzylinder werden die Stiftpaare mit einem winkeligen Versatz zueinander vormontiert, wodurch ein größeres Montagevolumen als bei ausgerichteten Stiftpaaren möglich ist. Darüber hinaus kann die Axiallänge des Schließzylinders durch Verwendung einer kleineren Zahl von Zuhaltungen verkürzt werden.In the locking cylinder according to the invention, the pairs of pins are preassembled with an angular offset from one another, as a result of which a larger assembly volume is possible than with aligned pairs of pins. In addition, the axial length of the locking cylinder can be shortened by using a smaller number of tumblers.

In einer bevorzugten Ausführungsform werden die genannten Radialbohrungen in einem Einsatzteil für ein Schloß gebildet. Somit können die verschiedenen Schlösser einer Kollektion vormontiert, kann die entsprechende Zahl von Einsatzteilen gleicher Kombination, die vorteilhafterweise gleich sind, vorgefertigt werden und können die genannten Einsatzteile in ihr entsprechendes Schloß kurz vor dem endgültigen Einrasten des Zylinderkerns eingebaut werden.In a preferred embodiment, the radial bores mentioned are formed in an insert part for a lock. Thus, the different locks of a collection can be pre-assembled, the corresponding number of insert parts of the same combination, which are advantageously the same, can be prefabricated and the insert parts mentioned can be installed in their corresponding lock shortly before the cylinder core is finally locked in place.

Die Erfindung wird besser verständlich beim Lesen der folgenden Beschreibung unter Bezugnahme auf die beigeheftete Zeichnung, in der

  • Fig. 1 eine schematische Ansicht im Diametralschnitt eines Schließzylinders nach einem Ausführungsbeispiel der Erfindung ist, in der der Zylinderkern eingebaut und der Schlüssel in Entriegelungsstellung eingesetzt ist ;
  • Fig. 2 zeigt, analog zu Fig. 1, den Schließzylinder in Verriegelungsstellung ;
  • Fig. stellt den Schließzylinder der Figuren 1 und 2 im Verlauf der Zylinderkernmontage dar, wobei die rechte und linke Partie jeweils eine Variante des Innenanschlags veranschaulicht, und
  • Fig. 4 ist die gleiche wie Fig. 1, doch zeigt der rechte und der linke Teil jeweils eine weitere Variante des Außenanschlags.
The invention will be better understood by reading the following description with reference to the attached drawing, in which
  • Fig. 1 is a schematic view in diametrical section of a lock cylinder according to an embodiment of the invention, in which the cylinder core is installed and the key is inserted in the unlocked position;
  • FIG. 2 shows, analogously to FIG. 1, the locking cylinder in the locking position;
  • 1 shows the locking cylinder of FIGS. 1 and 2 in the course of the cylinder core assembly, the right and left parts each illustrating a variant of the inner stop, and
  • Fig. 4 is the same as Fig. 1, but the right and left parts each show a further variant of the external stop.

Der Schlüssel 1 ist an seinem Umfang mit Einschnitten 1' versehen, die im dargestellten Beispiel in einer einzigen Lage oder Reihe angeordnet sind. Diese Einschnitte 1' von variabler Tiefe wirken in klassischer Weise mit den Kernstiftpaaren 2 und den Gehäusestiftpaaren 3 zusammen, die jeweils von einer Feder 4 zurückgeholt werden, um in Entriegelungsstellung (Fig. 1 und 4) die Trennungsebene zwischen den Stiften 2 und 3 in Berührung mit der Mantellinie des Zylinderkerns zu bringen, wodurch sich dieser in bezug auf das Zylindergehäuse 6 frei drehen kann. Dagegen ist bei Abwesenheit des Schlüssels (Fig. 2) oder bei einem falschen Schlüssel die Trennungsebene aller Stifte 2, 3 nicht in Berührung mit der Mantellinie des Zylinderkerns 5, und dieser ist in bezug auf das Zylindergehäuse 6 verriegelt.The key 1 is provided on its circumference with incisions 1 ', which are arranged in a single layer or row in the example shown. These incisions 1 'of variable depth interact in a classic manner with the core pin pairs 2 and the housing pin pairs 3, each of which is brought back by a spring 4, in order to be in the unlocked position (FIGS. 1 and 4), the parting plane between the pins 2 and 3 in contact to bring with the surface line of the cylinder core, whereby this can rotate freely with respect to the cylinder housing 6. In contrast, the absence of the key sels (Fig. 2) or with a wrong key, the parting plane of all pins 2, 3 does not come into contact with the surface line of the cylinder core 5, and this is locked with respect to the cylinder housing 6.

Im dargestellten Beispiel hat der Schlüssel 1 ein im allgemeinen (von den Schlüsseleinschnitten 1' abgesehen) kreisförmiges Profil und ist an seinem freien Ende mit einem Rastansatz 1" versehen, der mit einer Aussparung 5' entsprechender Form im Zylinderkern 5 zusammenwirkt, um die richtige Stellung des Schlüssels 1 in bezug auf den Zylinderkern 5 sicherzustellen. In einer Variante kann der Schlüssel 1 ein nichtkreisförmiges Profil haben und der Schlüsselkanal ein gleiches Profil aufweisen.In the example shown, the key 1 has a generally circular profile (apart from the key incisions 1 ') and is provided at its free end with a latching projection 1 "which cooperates with a recess 5' of corresponding shape in the cylinder core 5 to ensure the correct position of the key 1 with respect to the cylinder core 5. In one variant, the key 1 can have a non-circular profile and the key channel can have the same profile.

Die Stifte 2 und 3 können durch Kugeln ersetzt werden, deren Durchmesser der Nutzhöhe des Stiftes entspricht.Pins 2 and 3 can be replaced by balls, the diameter of which corresponds to the useful height of the pin.

Im dargestellten Beispiel ist das Zylindergehäuse 6 ein unabhängiges Teil, das in ein Schloß (nicht dargestellt) eingesetzt werden kann. Erfindungsgemäß umfaßt das Zylindergehäuse 6 Radialbohrungen 6', in denen jeweils ein Stiftepaar 2, 3 mit Federmitteln untergebracht ist. Jede Bohrung 6' geht quer durch das Teil 6 hindurch und ist an dessen Außenumfang durch einen Ring 7 verschlossen, der allen Bohrungen 6' in einer oder mehreren Lagen (Fig. 1 bis 3) gemeinsam ist. Als Variante kann jede Bohrung 6' durch einen verformbaren Nocken 8 (Fig. 4 rechts) verschlossen sein. In diesen beiden Fällen stützt sich die Rückholfeder 4 des Stiftepaares 2-3 auf den Anschlag 7 oder 8 ab.In the example shown, the cylinder housing 6 is an independent part that can be used in a lock (not shown). According to the invention, the cylinder housing 6 comprises radial bores 6 ', in each of which a pair of pins 2, 3 is accommodated with spring means. Each bore 6 'passes through the part 6 and is closed on its outer circumference by a ring 7 which is common to all the bores 6' in one or more layers (FIGS. 1 to 3). As a variant, each bore 6 'can be closed by a deformable cam 8 (FIG. 4, right). In these two cases, the return spring 4 of the pair of pins 2-3 is supported on the stop 7 or 8.

Bei einer in Fig. 4 links dargestellten Variante dient ein elastischer Ring 11, der allen Bohrungen 6' einer gleichen Lage gemeinsam ist, gleichzeitig als Außenverschluß der Bohrung wie auch als Federmittel für das Stiftepaar 2-3 in seiner Bohrung 6'.In a variant shown on the left in FIG. 4, an elastic ring 11, which is common to all bores 6 'in the same position, serves simultaneously as an external closure of the bore and also as a spring means for the pair of pins 2-3 in its bore 6'.

An ihren Innenenden sind die Bohrungen 6' durch einen gemeinsamen Ring 9 (rechte Seite in Fig. 3) oder aber durch einen Nocken 10 (linke Seite in Fig. 3) verschlossen, die beim Einstecken des Zylinderkerns 5 in dessen Bohrung im Gehäuse 6 ausgeworfen bzw. abgeschnitten werden.At their inner ends, the bores 6 'are closed by a common ring 9 (right side in FIG. 3) or by a cam 10 (left side in FIG. 3), which are ejected when the cylinder core 5 is inserted into its bore in the housing 6 or be cut off.

Nach dem Einstecken rastet der Zylinderkern 5 am Zylindergehäuse 8 ein, beispielsweise mittels eines elastischen Nockens 5" ; sein Drehwinkel wird im übrigen durch Anschläge (nicht gezeigt) begrenzt.After plugging in, the cylinder core 5 engages on the cylinder housing 8, for example by means of an elastic cam 5 "; its angle of rotation is otherwise limited by stops (not shown).
