Abstract

The invention relates to a snap-in latching cylinder for cylinder locks, which includes a retaining pin which is returned by a spring onto the outside of the cylinder and which shifts inwards counter to the effect of this spring during the insertion of the cylinder into the lock and, after the end of the insertion operation, engages behind a stop of the cylinder seat in the lock body under the effect of the said spring. The cylinder according to the invention is characterised in that the retaining pin (5) comprises, before installation on the outside of the cylinder, a projecting part (6) which is contained in a plane parallel to the axis of the cylinder and the front edge (8) of which has a slope diverging towards the rear end of the cylinder, whilst its rear edge (9) is essentially at right angles to the cylinder axis. <IMAGE>

Description

Die Erfindung bezieht sich auf einen einrastbaren Schließzylinder für Zylinderschlösser, zu dem ein Halterungsstift gehört, den eine Feder an die Außenseite des Zylinders zurückholt und der gegen die Wirkung dieser Feder beim Einstecken des Zylinders ins Schloß nach innen ausweicht, um dann unter der Wirkung der genannten Feder hinter einem Anschlag des Zylindersitzes im Schloßkörper einzurasten, nachdem der Einsteckvorgang beendet ist.The invention relates to a lockable cylinder lock for cylinder locks, to which a retaining pin belongs, which a spring brings back to the outside of the cylinder and which deflects inward against the action of this spring when the cylinder is inserted into the lock, and then under the action of the aforementioned Lock the spring behind a stop of the cylinder seat in the lock body after the insertion process is finished.

Die bekannten Zylinder dieser Art werden in Fällen verwendet, in denen Schloß und Zylinder getrennt vormontiert werden und der Zylinder erst später im Schloß befestigt wird. Dies geschieht z. B. in der Automobilindustrie bei einer Hauptschlüsselanlage.The known cylinders of this type are used in cases in which the lock and cylinder are preassembled separately and the cylinder is only later attached to the lock. This happens e.g. B. in the automotive industry with a master key system.

Bei diesen bekannten Zylindern ist der Halterungsstift, ebenso wie die Sperrstifte des Schließzylinders, gleitend in einer Aussparung senkrecht zur Achse des Zylinders untergebracht. Dieser Halterungsstift, der beim Versuch, den Zylinder herauszuziehen, auf Biegung beansprucht wird, muß deshalb recht dick sein. Er muß zudem an der Außenseite des Zylinders einen starken Vorsprung haben, um ein sicheres und festes Einrasten zu gewährleisten. Die Vorderseite des Halterungsstiftes muß eine gerundete Kante aufweisen, damit sich dieser automatisch beim Einstecken wegbewegt, und diese gerundete Kante setzt die mechanische Festigkeit des Stiftes weiter herab. All diese Merkmale machen einen solchen Stift umfangreich, kostspielig und nicht immer sicher.In these known cylinders, the mounting pin, like the locking pins of the locking cylinder, is slidably accommodated in a recess perpendicular to the axis of the cylinder. This mounting pin that bends when trying to pull out the cylinder must be quite thick. He must also have a strong projection on the outside of the cylinder to ensure a secure and firm engagement. The front of the support pin must have a rounded edge so that it automatically moves away when inserted, and this rounded edge further reduces the mechanical strength of the pin. All of these features make such a pen bulky, expensive and not always safe.

Ziel der Erfindung ist der Erhalt eines Schließzylinders der beschriebenen Art, bei dessen Einführung der Stift einen sehr kleinen Vorsprung haben kann und dennoch dem Zylinder eine sehr hohe Festigkeit gegen Herausziehen verleiht.The aim of the invention is to obtain a lock cylinder of the type described, the pin of which can have a very small projection when it is introduced and nevertheless gives the cylinder a very high level of strength against being pulled out.

Deshalb ist der erfindungsgemäße Zylinder dadurch gekennzeichnet, daß der genannte Halterungsstift vor der Montage außen am Zylinder einen vorspringenden Teil umfaßt, der in einer Ebene parallel zur Achse des Zylinders enthalten ist und,dessen Verderkante mit einer zum hinteren Ende des Zylinders zu divergierenden Steigung versehen ist, während die hintere Kante dieses vorspringenden Teils im wesentlichen rechtwinkling zur Zylinderachse verläuft.Therefore, the cylinder according to the invention is characterized in that said mounting pin comprises, before mounting on the outside of the cylinder, a projecting part which is contained in a plane parallel to the axis of the cylinder and the verder edge of which is provided with a slope which diverges towards the rear end of the cylinder while the rear edge of this projecting part is substantially perpendicular to the cylinder axis.

Beim erfindungsgemäßen Schließzylinder wirkt der Halterungsstift durch Knicken, so daß er dünner sein kann. Zudem kann die Form des Vorsprungs mit Präzision durch Ausstanzen erhalten werden, und zwar mit kleineren Bockabmessungen.In the locking cylinder according to the invention, the mounting pin acts by kinking so that it can be thinner. In addition, the shape of the protrusion can be obtained with precision by punching out, with smaller trestle dimensions.

Vorzugsweise wird der genannte vorspringende Teil des Halterungsstiftes durch Verlängerung des ebenfalls in einer Ebene parallel zur Zylinderachse enthaltenen Stiftkörpers geformt, wobei sich die Rückholfeder auf diesen Körper abstützt. In einer bevorzugten Ausführungsform umfaßt der genannte Körper einen im wesentlichen rechtwinkligen Flügel, wodurch eine bessere Führung und eine höhere mechanische Festigkeit für den Stift sichergestellt werden.Said projecting part of the holding pin is preferably formed by extending the pin body, which is likewise contained in a plane parallel to the cylinder axis, the return spring being supported on this body. In a preferred embodiment said body comprises a substantially right angle wing, which ensures better guidance and greater mechanical strength for the pin.

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

  • - die Fig. 1 eine schematische Draufsicht eines erfindungsgemäßen Schließzylinders ist;
  • - Fig. 2 ist eine Draufsicht des Halterungsstiftes;
  • - Fig. 3 ist eine Seitenansicht des Halterungsstiftes, und
  • - Fig. 4 ist eine Vorderansicht des Halterungsstiftes.
The invention will be better understood by reading the following description with reference to the attached drawing, in which
  • - Figure 1 is a schematic plan view of a lock cylinder according to the invention;
  • 2 is a top view of the support pin;
  • - Fig. 3 is a side view of the support pin, and
  • 4 is a front view of the support pin.

Der Zylinder 1 umfaßt an seinem vorderen Teil einen Mitnehmer 2 und an seinem hinteren Teil den Eintritt für den Schlüssel 3. Außer den Sperrstiften 4 umfaßt er.einen Halterungsstift 5 nahe am vorderen Ende.The cylinder 1 comprises a driver 2 on its front part and the entry for the key 3 on its rear part. In addition to the locking pins 4, it also comprises a mounting pin 5 near the front end.

Der Stift 5 (Figuren 2 - 4) umfaßt vor dem Einführen des Zylinders ins Schloß einen außen am Zylinder vorstehenden Teil 6. Dieser Teil 6 ist im wesentlichen eben und sitzt in einer Ebene parallel zur Achse des Zylinder 1. Der Teil 6 ist die Verlängerung des Körpers. 7 des Halterungsstiftes 5.Before the cylinder is inserted into the lock, the pin 5 (FIGS. 2-4) comprises a part 6 projecting outside the cylinder. This part 6 is essentially flat and sits in a plane parallel to the axis of the cylinder 1. The part 6 is the extension of the body. 7 of the mounting pin 5.

Der Teil 6 umfaßt eine Vorderkante mit einer Steigung 8, die zum hinteren Ende des Zylinders 1 zu divergiert. Die Hinterkante 9 des Teils 6 dagegen verläuft im wesentlichen rechtwinkling zur Achse des Zylinders und umfaßt eine Einkerbung 10 zum festen Einhaken am Aschlag (nicht dargestellt) des Schloßkörpers. Der Körper 7 ist durch einen rechtwinkligen Verstärkungs- und Führungsflügel verlängert.The part 6 comprises a leading edge with a slope 8 which diverges to the rear end of the cylinder 1. The rear edge 9 of part 6, on the other hand, extends essentially at right angles to the axis of the cylinder and comprises a notch 10 for firmly hooking onto the stop (not shown) of the lock body. The body 7 is extended by a right-angled reinforcement and guide wing.
