Description

Die Erfindung betrifft einen Schließzylinderschlüssel nach dem Oberbegriff des Anspruchs 1.The invention relates to a lock cylinder key according to the preamble of claim 1.

Ein derartiger Schließzylinderschlüssel ist bekannt aus der DE-OS 24 11 362 und EP-A-0 356 032, wobei beiderseits des Kernbereiches des Schließzylinderschlüssels rechtwinklig zu diesem verlaufende Hochrippen vorgesehen sind. Mittels stirnseitig eingeschnittener Schließkerben werden Zusatzstifte gesteuert. Diese derart ausgerichteten Hochrippen führen zu einer größeren Dimension des Schlüsselschaftes in Dickenrichtung. Im Verhältnis zum Überstand der Hochrippe läßt sich auch keine optimale Anzahl von Schließkerben mit normal großen Stufensprüngen unterbringen. Dies reduziert die Permutationsmöglichkeit.Such a locking cylinder key is known from DE-OS 24 11 362 and EP-A-0 356 032, wherein on both sides of the core area of the locking cylinder key perpendicular ribs are provided. Additional pins are controlled by means of cut-in notches on the front. These high ribs aligned in this way lead to a larger dimension of the key shaft in the thickness direction. In relation to the protrusion of the high rib, it is also not possible to accommodate an optimal number of locking notches with normal size increments. This reduces the possibility of permutation.

Dem Gegenstand der Erfindung liegt die Aufgabe zugrunde, einen Schließzylinderschlüssel der in Rede stehenden Art in herstellungstechnisch einfacher Weise so auszugestalten, daß bei schmaler Bauform die Permutationsmöglichkeit erhöht ist.The object of the invention is based on the design of a lock cylinder key of the type in question in a technically simple manner in such a way that the permutation possibility is increased in a narrow design.

Gelöst wird diese Aufgabe bei einem gattungsgemäßen Schließzylinderschlüssel durch die Merkmale des kennzeichnenden Teils des Anspruchs 1.This object is achieved in a generic lock cylinder key by the features of the characterizing part of claim 1.

Zufolge derartiger Ausgestaltung ist ein Schließzylinder der in Rede stehenden Art angegeben, der bei einfachem Aufbau und räumlich kleiner Dimension in Dickenrichtung eine erhöhte Permutationsmöglichkeit besitzt. Einerseits ist der Querschnitt der Hochrippe zur Profilvariation herangezogen. Andererseits erlaubt die geneigt zur Längsmittelebene des Kernbereiches verlaufende Hochrippe eine optimale Anzahl von Schließkerben mit normal großen Stufensprüngen. Zum einen können sich die Schließkerben in dem Querschnitt der Hochrippe selbst erstrecken. Zum anderen sind sie einschneidbar bis über die Längsmittelebene des Kernbereiches, so daß eine insgesamt große Länge zum Einarbeiten der Schließkerben mit unterschiedlichen Einschnittstiefen zur Verfügung steht. Dennoch unterliegt der Schlüsselschaft selbst bei maximal tiefen Schließkerben keiner gefährdenden Schwächung. Das Maß, das für das Einschneiden der Schließkerben zur Verfügung steht, kann größer sein als die Dicke des Kernbereiches, und zwar in Querrichtung zur Längsmittelebene des Kernbereiches gesehen. Insbesondere bietet sich die Z-Form für den Kernbereich an. Die einzelnen Abschnitte der Z-Form können geradlinig oder auch als geschwungene Bögen gestaltet sein.As a result of such a design, a locking cylinder of the type in question is specified, which is simple Structure and spatially small dimension in the thickness direction has an increased permutation possibility. On the one hand, the cross section of the rib is used for profile variation. On the other hand, the high rib, which is inclined to the longitudinal center plane of the core area, allows an optimal number of locking notches with normal step increments. On the one hand, the closing notches can extend in the cross section of the raised rib itself. On the other hand, they can be cut into beyond the longitudinal central plane of the core area, so that an overall large length is available for incorporating the locking notches with different incision depths. Nevertheless, the key shank is not subject to a dangerous weakening even with maximum deep notches. The dimension that is available for cutting the locking notches can be greater than the thickness of the core area, specifically in the transverse direction to the longitudinal center plane of the core area. The Z shape is particularly suitable for the core area. The individual sections of the Z shape can be designed in a straight line or as curved arches.

Der Gebrauchswert des Schließzylinderschlüssels wird dadurch erhöht, daß der Schlüssel als Wendeschlüssel ausgestaltet ist mit neben den Wurzeln der Z-Schenkel entspringenden Hochrippen. Der Schlüssel ordnet daher ungeachtet seiner Einschubstellung stets vorschriftsmäßig die Zuhaltungen des Schließzylinders ein.The utility value of the lock cylinder key is increased by the fact that the key is designed as a reversible key with raised ribs that originate next to the roots of the Z-legs. The key therefore always classifies the tumblers of the locking cylinder regardless of its insertion position.

Eine vorteilhafte Weiterbildung besteht gemäß der Erfindung darin, daß der Scheitel der Hochrippe etwa bis zur Verlängerung der durch die Außenseitenflanken der Z-Schenkel gelegten Ebene reicht. Demgemäß erstrecken sich die Hochrippen noch im Bereich zwischen beiden Außenseitenflanken. Sie überragen nicht das Gesamtprofil des Kernbereiches, in Querrichtung zur Längsmittelebene desselben gesehen.An advantageous further development according to the invention is that the apex of the raised rib extends approximately to the extension of the plane laid by the outside flanks of the Z-legs. Accordingly, the raised ribs still extend in the area between the two outer side flanks. They do not exceed the overall profile of the Core area, seen in the transverse direction to the longitudinal median plane of the same.

Eine optimale Anzahl von Stufensprüngen bei schmaler Bauform wird dadurch erzielt, daß der Winkel zwischen Längsmittelebene der Hochrippe und Längsmittelebene des Kernbereiches ca. 35-40° beträgt. Legt man z. B. eine Gesamtdicke des Schlüsselschaftes von ca. 3,3 mm zugrunde, so können insgesamt 10 verschieden große Einschnittstiefen gut untergebracht werden, und zwar bei einem Stufensprung von 0,36-0,4 mm. Angepaßt ist dieser Winkel auch der Zuspitzung der Kernstifte.An optimal number of increments with a narrow design is achieved in that the angle between the median longitudinal plane of the raised rib and the median longitudinal plane of the core area is approximately 35-40 °. If you put z. B. based on a total thickness of the key shank of approx. 3.3 mm, a total of 10 differently large incision depths can be accommodated, with a step increment of 0.36-0.4 mm. This angle is also adapted to the tapering of the core pins.

Weiterhin ist hervorzuheben, daß die eine Hochrippenflanke etwa bis zur Längsmittelebene des Kernbereiches reicht. Der Querschnitt der Hochrippe und der Kernbereich lassen sich demzufolge optimal aufeinander abstimmen unter Erzielung eines kräftigen Schlüsselschaftes.It should also be emphasized that the one high rib flank extends approximately to the longitudinal central plane of the core area. The cross-section of the rib and the core area can therefore be optimally coordinated with each other to achieve a strong key shaft.

Es ist ferner möglich, ergänzende Schließkerben an der Außenecke zwischen Außenseitenflanke des Z-Schenkels und angrenzender Außenfläche des Z-Mittelbereiches vorzusehen. Mittels dieser ergänzenden Schließkerben können weitere Zuhaltungsstifte des Zylinderkerns gesteuert werden unter Erhöhung der Permutationsmöglichkeit.It is also possible to provide additional locking notches on the outer corner between the outer side flank of the Z leg and the adjacent outer surface of the Z central region. By means of these additional locking notches, further tumbler pins of the cylinder core can be controlled while increasing the possibility of permutation.

Der den Schlüssel aufnehmende Schließzylinder zeichnet sich dadurch aus, daß die Verschiebeebene der Hauptzuhaltungsstifte spitzwinklig geneigt zur Längsmittelebene des Schlüsselkanals liegt, welcher einen ersten Schlüsselschlitz-Kanalbereich für die Hochrippe ausbildet und daß parallel zur Erstreckung des zweiten Schlüsselschlitz-Kanalbereiches ein ergänzender Zuhaltungsstift geführt ist. Es ergibt sich hier eine räumlich günstige Anordnung der ergänzenden Zuhaltungsstifte.The key cylinder holding the key is characterized in that the displacement plane of the main tumbler pins is inclined at an acute angle to the longitudinal center plane of the key channel, which forms a first key slot channel area for the rib, and that an additional tumbler pin is guided parallel to the extension of the second key slot channel area. This results in a spatially favorable arrangement of the additional tumbler pins.

Von Vorteil erweist es sich dabei, daß der ergänzende Zusatzstift in der Verschiebeebene der Hauptzuhaltungsstifte verlagerbar ist. Es ist möglich, daß die Zuhaltungsstifte und die Hauptzuhaltungsstifte sich genau gegenüberliegen. Jedoch können die ergänzenden Zuhaltungsstifte auf Lücke versetzt sein zu den Hauptzuhaltungsstiften. Auch wäre die Anordnung einer weiteren ergänzenden Zuhaltungsstiftreihe möglich. Diese würde dann etwa rechtwinklig zur Längsmittelebene des Kernbereiches ausgerichtet sein.It proves advantageous that the supplementary additional pin is displaceable in the shifting plane of the main tumbler pins. It is possible that the tumbler pins and the main tumbler pins face each other exactly. However, the supplementary tumbler pins may be gaped to the main tumbler pins. It would also be possible to arrange a further additional tumbler pin series. This would then be aligned approximately at right angles to the longitudinal center plane of the core area.

Schließlich besteht ein vorteilhaftes Merkmal noch darin, daß die beiderseitigen freien Flanken der Hochrippe auf der einen Seite diesseitig und auf der anderen Seite jenseits der Längsmittelebene des Kernbereiches beginnen.Finally, an advantageous feature is that the free flanks of the rib on both sides begin on one side on this side and on the other side beyond the longitudinal median plane of the core region.

Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnungen erläutert. Es zeigt

An embodiment of the invention is explained below with reference to the drawings. It shows

Fig. 3
in a greatly enlarged representation, a cross section through the profile double cylinder at the level of a main tumbler pin.

Der als Profil-Doppelzylinder ausgestaltete Schließzylinder 1 besitzt ein Zylindergehäuse 2, welches sich aus zwei Gehäusehälften zusammensetzt, die durch einen Steg 3 miteinander verbunden sind. Im Bereich zwischen den beiden Zylindergehäusehälften ist in bekannter Weise ein Schließglied 4 angeordnet.The locking cylinder 1 designed as a profile double cylinder has a cylinder housing 2, which is composed of two housing halves which are connected to one another by a web 3. In the area between the two cylinder housing halves, a closing member 4 is arranged in a known manner.

Das Zylindergehäuse 2 setzt sich aus einem im Querschnitt kreisförmigen Abschnitt 5 und einem radial dazu stehenden Flanschabschnitt 6 zusammen. In dem kreisförmigen Abschnitt 5 des Zylindergehäuses 2 ist eine Kernbohrung 7 vorgesehen, in welcher ein Zylinderkern 8 drehbar lagert. Die inneren Enden beider Zylinderkerne 8 tragen das Schließglied 4.The cylinder housing 2 is composed of a section 5 with a circular cross section and a flange section 6 standing radially thereto. In the circular section 5 of the cylinder housing 2, a core bore 7 is provided, in which a cylinder core 8 is rotatably supported. The inner ends of both cylinder cores 8 carry the closing member 4.

In der Längsmittelebene des Profil-Doppelzylinders sind reihenförmig hintereinander angeordnete Hauptzuhaltungsstifte 9 vorgesehen. Jeder Hauptzuhaltungsstift 9 setzt sich zusammen aus einem Kernstift 10 und einem Gehäusestift 11. Zur Aufnahme jedes Hauptzuhaltungsstiftes 9 dienen im Flanschabschnitt 6 und Zylinderkern 8 eingearbeitete Bohrungen 12 und 13, welche miteinander fluchten. Die gehäuseseitige Bohrung 12 dient ferner noch zur Aufnahme einer Stiftfeder 14. Diese beaufschlagt das untere Stirnende des Gehäusestiftes 11, welcher bei nicht eingestecktem Schlüssel 15 den Kernstift 10 bis zu seinem Anschlag in den Zylinderkern 8 hineintreibt. Da der Gehäusestift 11 dann auch in die Bohrung 13 des Zylinderkernes 8 hineinragt, ist der dieser an einem Drehen gehindert.Main tumbler pins 9 are provided in rows in the longitudinal center plane of the profile double cylinder. Each main tumbler pin 9 is composed of a core pin 10 and a housing pin 11. To accommodate each main tumbler pin 9, bores 12 and 13 are incorporated in the flange section 6 and cylinder core 8, which are aligned with one another. The housing-side bore 12 also serves to receive a pin spring 14. This acts on the lower end of the housing pin 11, which drives the core pin 10 into the cylinder core 8 until it stops when the key 15 is not inserted. Since the housing pin 11 then also projects into the bore 13 of the cylinder core 8, the latter is prevented from rotating.

Zur Aufnahme des Schlüssels 15, welcher beim Ausführungsbeispiel als Wendeschlüssel gestaltet ist, bildet der Zylinderkern 8 einen dem Querschnittsprofil des Schlüsselschaftes angepaßten Schlüsselkanal 16 aus.To receive the key 15, which in the exemplary embodiment is designed as a reversible key, the cylinder core 8 forms a key channel 16 which is adapted to the cross-sectional profile of the key shaft.

Der Schlüsselschaft besitzt im einzelnen einen Z-förmigen Kernbereich SK. Dieser setzt sich zusammen aus den beiden parallel zueinander liegenden Z-Schenkeln 17, die durch einen Z-Mittelbereich 18 untereinander verbunden sind. Im Bereich der Wurzeln W entspringen Hochrippen 19, 20, vom Kernbereich SK, deren Längsmittelebene LH-LH spitzwinklig geneigt liegt zur Längsmittelebene LK-LK des Kernbereiches SK. Die Längsmittelebene LH-LH der die Hauptzuhaltungsstifte 9 einordnenden Hochrippe 19 fällt gemäß Fig. 3 zusammen mit der Verschiebeebene VE-VE der Hauptzuhaltungsstifte. Aus dieser Figur ist ferner ersichtlich, daß der Scheitel 19', 20' der Hochrippen 19, 20 etwa bis zur Verlängerung der durch die Außenseitenflanken 17' der Z-Schenkel 17 belegten Ebene E reicht. Die beiden parallel zueinander liegenden Ebenen E bestimmen die Gesamtdicke D des Schlüsselschaftes. Innerhalb dieser erstrecken sich die Hochrippen 19, 20.The key shank has a Z-shaped core area SK. This is composed of the two Z-legs 17 lying parallel to one another, which are connected to one another by a Z-central region 18. In the area of the roots W, raised ribs 19, 20 arise from the core area SK, whose longitudinal center plane LH-LH is at an acute angle to the longitudinal center plane LK-LK of the core area SK. The longitudinal center plane LH-LH of the rib 19, which arranges the main tumbler pins 9, according to FIG. 3, coincides with the displacement plane VE-VE of the main tumbler pins. From this figure it can also be seen that the apex 19 ', 20' of the raised ribs 19, 20 extends approximately to the extension of the plane E occupied by the outer side flanks 17 'of the Z-leg 17. The two planes E lying parallel to one another determine the total thickness D of the key shank. The ribs 19, 20 extend within this.

Die durch die Verschiebeebene VE-VE der Hauptzuhaltungsstifte 9 gelegte Längsmittelebene LH-LH der Hochrippe 19 bzw. 20 und Längsmittelebene LK-LK schließen zwischen sich einen Winkel Alpha von etwa 40° ein. Ferner ist aus Fig. 3 ersichtlicht, daß die eine Hochrippenflanke 19'', 20'' etwa bis zur Längsmittelebene LK-LK des Kernbereiches SK reicht.The longitudinal center plane LH-LH of the high rib 19 or 20 and the longitudinal center plane LK-LK, which are placed through the displacement plane VE-VE of the main tumbler pins 9, enclose an angle alpha of approximately 40 ° between them. 3 that one high rib flank 19 ″, 20 ″ extends approximately to the longitudinal center plane LK-LK of the core area SK.

Von dem Scheitel 19', 20' jeder Hochrippe 19, 20 sind Schließkerben 21 eingeschnitten derart, daß die auf gleicher Querschnittsebene des Schlüsselschaftes befindlichen Schließkerben gleiche Tiefe aufweisen zufolge der Tatsache, daß es sich um einen Wendeschlüssel handelt. Mit strichpunktierten Linien ist in Fig. 3 angedeutet, daß zehn verschieden tiefe Schließkerben möglich sind. Der Abstand einander benachbarter Schließkerben entspricht einem Stufensprung S. Im vorliegenden Fall ist ein Stufensprung von 0,36 mm gewählt. Die größte Einschnittstiefe kann demgemäß 3,6 mm betragen. Dieses Maß ist größer als die Dicke D von 3,3 mm des Schlüssel-Kernbereiches SK. Bei max. großer Einschnittstiefe ist die Schließkerbe 21 bis über die Längsmittelebene LK-LK des Kernbereiches SK einschneidbar. Dennoch verbleibt noch genügend Material am Kernbereich SK, so daß der Schlüsselschaft nicht gefährdend geschwächt wird.Locking notches 21 are cut from the apex 19 ', 20' of each raised rib 19, 20 such that the locking notches located on the same cross-sectional plane of the key shaft have the same depth due to the fact that it is a reversible key. With dash-dotted lines it is indicated in Fig. 3 that ten different depth closing notches are possible. The distance between the adjacent notches corresponds to a step jump S. In the present case, a step jump of 0.36 mm is selected. The greatest depth of cut can accordingly be 3.6 mm. This dimension is greater than the thickness D of 3.3 mm of the key core area SK. At max. With a large depth of cut, the closing notch 21 can be cut into beyond the longitudinal center plane LK-LK of the core area SK. Still remains enough material at the core area SK so that the key shaft is not weakened in a dangerous manner.

Ferner sind noch ergänzende Schließkerben 22 an der Außenecke zwischen Außenseitenflanke 17' des Z-Schenkels 17 und der angrenzenden Außenfläche 23 des Z-Mittelbereiches 18 vorgesehen. Diese dienen zur Steuerung ergänzender Zuhaltungsstifte 24. Ein der Zylinderkern-Drehfuge F zugekehrter Kopf begrenzt die Eintrittstiefe des ergänzenden Zusatzstiftes 24 in Verbindung mit einer stufenförmig abgesetzten Bohrung für die ergänzenden Zuhaltungsstifte 24. Ist der vorschriftsmäßige Schlüssel 15 eingeschoben, so können bei Schließdrehung die ergänzenden Zuhaltungsstifte 24 aus einer Längsnut 25 des Zylindergehäuses ausweichen, so daß sie die Schließdrehung des Zylinderkerns 8 nicht stören. Fehlt bei einem Schlüssel die ergänzende Schließkerbe 22 oder ist diese nicht genug tief eingeschnitten, so ist das vollständige Auweichen des ergänzenden Zuhaltungsstiftes 24 nicht möglich. Die Schließdrehung des Zylinderkerns 8 ist somit blokkiert.In addition, additional closing notches 22 are provided on the outer corner between the outer side flank 17 ′ of the Z leg 17 and the adjacent outer surface 23 of the Z middle region 18. These serve to control additional tumbler pins 24. A head facing the cylinder core rotary joint F limits the depth of entry of the additional tumbler pin 24 in connection with a step-like offset hole for the additional tumbler pins 24. If the prescribed key 15 is inserted, the additional tumbler pins can be turned when the lock is turned 24 dodge from a longitudinal groove 25 of the cylinder housing so that they do not interfere with the closing rotation of the cylinder core 8. If the additional locking notch 22 is missing from a key or if it is not cut deep enough, it is not possible for the additional tumbler pin 24 to completely escape. The closing rotation of the cylinder core 8 is thus blocked.

Die Fig. 2 und 3 veranschaulichen, daß die Verschiebeebene VE-VE der Hauptzuhaltungsstifte 9 spitzwinklig geneigt zur Längsmittelebene A-A des Schlüsselkanals 16 liegt. Dieser bildet einen ersten Schlüsselschlitz-Kanalbereich 16' für die Hochrippe 19 aus und erstreckt sich den ergänzenden Zuhaltungsstiften 24 gegenüber. Parallel zu diesen ergänzenden Zuhaltungsstiften 24 verläuft der zweite Schlüsselschlitz-Kanalbereich 16''. Das bedeutet, daß der ergänzende Zuhaltungsstift 24 in der Verschiebeebene VE-VE der Hauptzuhaltungsstifte 9 verlagerbar ist. Entweder ist es möglich, wie dargestellt, daß der ergänzende Zuhaltungsstift 24 mit einem Hauptzuhaltungsstift 9 fluchtet oder auf Lücke versetzt angeordnet ist zu den Hauptzuhaltungsstiften.2 and 3 illustrate that the displacement plane VE-VE of the main tumbler pins 9 is inclined at an acute angle to the longitudinal center plane AA of the key channel 16. This forms a first key slot channel area 16 ′ for the raised rib 19 and extends opposite the additional tumbler pins 24. The second key slot channel region 16 ″ runs parallel to these supplementary tumbler pins 24. This means that the additional tumbler pin 24 is displaceable in the displacement plane VE-VE of the main tumbler pins 9. Either it is possible, as shown, for the supplementary tumbler pin 24 to have a master tumbler pin 9 is aligned or offset to the main tumbler pins.

Sodann ist noch festzuhalten, daß die beiderseitigen freien Flanken 19'', 19''' bzw. 20'', 20''' auf der einen Seite diesseitig und auf der anderen Seite jenseits der Längsmittelebene LK-LK des Kernbereiches SK beginnen. Der Abstand zwischen dem Beginn der beiden freien Flanken zur Längsmittelebene LK-LK des Kernbereiches SK ist dabei etwa gleich. Die Hochrippen 19, 20 sind daher genügend breit dimensioniert und gestatten ein gutes Einordnen der Hauptzuhaltungsstifte 9.It must then also be noted that the free flanks 19 ″, 19 ″ ″ or 20 ″, 20 ″ ″ on both sides begin on one side on this side and on the other side beyond the longitudinal center plane LK-LK of the core area SK. The distance between the beginning of the two free flanks to the longitudinal center plane LK-LK of the core area SK is approximately the same. The raised ribs 19, 20 are therefore of sufficiently wide dimensions and allow the main tumbler pins 9 to be well arranged.

Zusätzlich wären noch weitere ergänzende Zuhaltungsstifte einsetzbar. Beispielsweise könnte eine Reihe von ergänzenden Zuhaltungsstiften um etwa 45° versetzt zur Reihe der ergänzenden Zuhaltungsstifte 24 vorgesehen sein. Diese Reihe von Zuhaltungsstiften würde sich dann auf der linken Seite des Zylinderkerns erstrecken, wobei von Fig. 3 ausgegangen wird. Die betreffenden Vertiefungen wären in den Außenseitenflanken 17' der Z-Schenkel 17 anzuordnen.In addition, other additional tumbler pins could also be used. For example, a number of additional tumbler pins could be provided offset by approximately 45 ° to the row of additional tumbler pins 24. This row of tumbler pins would then extend on the left side of the cylinder core, starting from FIG. 3. The depressions in question would have to be arranged in the outer side flanks 17 ′ of the Z-legs 17.

Der Sicherheitswert ist dadurch erhöhbar, jede Hochrippe mit parazentrisch zueinander angeordneten Nuten auszustatten. Beispielsweise kann von jeder Flanke der Hochrippe je eine Nut ausgehen derart, daß diese in Übereinanderlage vorgesehen werden.The safety value can be increased by equipping each high rib with grooves arranged paracentrically to one another. For example, a groove can start from each flank of the raised rib in such a way that they are provided in a superimposed position.
