A key (17, 22, 31) for cylinder locks, the variation in profile of which is formed by zones which form individual ribs and grooves (18 to 21, 25 to 30, 37 to 41) and which are themselves formed by circles concentric about a straight centreline (23, 24, 32, 33, 34) running in the cross-section or the shank of the key and planes extending from the said centreline after the style of rays, characterized in that the key (17, 22, 31) is made as a flat key and the cross-section of the shank of the key has a number of straight centrelines (23, 24, 32, 33, 34) arranged one above the other in such a way that the zones forming grooves lie open towards the wide faces of the key.

Description

Die Erfindung betrifft einen Schlüssel für Zylinderschlösser, mit auf den Schlüsselbreitseiten angeordneten Nuten und Rippen zur Schließanlagen-Profilvariation.The invention relates to a key for cylinder locks, with grooves and ribs arranged on the key broad sides for locking system profile variation.

Um unterschiedliche Schließanlagen-Profilvariationen zu erhalten, ist es bekannt, die Nuten und Rippen im Querschnitt rechteckig oder trapezförmig zu gestalten und in entsprechendem Abstand zueinander anzuordnen. Die Möglichkeiten einer solchen Profilvariation sind begrenzt wegen der relativ großen Abstufungen.In order to obtain different locking system profile variations, it is known to make the grooves and ribs rectangular or trapezoidal in cross section and to arrange them at an appropriate distance from one another. The possibilities of such a profile variation are limited due to the relatively large gradations.

Dem Gegenstand der Erfindung liegt die Aufgabe zugrunde, einen Schlüssel der vorausgesetzten Art in herstellungstechnisch einfacher Weise so auszugestalten, daß trotz feiner Abstufung der Nuten und Rippen eine große Übersichtlichkeit vorliegt.The object of the invention is based on the object of designing a key of the type required in a manner that is simple to manufacture in such a way that, despite the fine gradation of the grooves and ribs, there is great clarity.

Gelöst wird diese Aufgabe dadurch, daß die Seitenwände der Nuten ausgerichtet sind auf mindestens eine im Schlüsselschaftquerschnitt verlaufende Gerade, welche den Mittelpunkt bildet zu den konvex gebogenen Bodenflächen dieser Nuten.This object is achieved in that the side walls of the grooves are aligned with at least one straight line running in the key shank cross section, which forms the center point to the convexly curved bottom surfaces of these grooves.

Zufolge derartiger Ausgestaltung läßt sich eine hohe Anzahl von Profilvariationen verwirklichen, ohne daß die Übersichtlichkeit darunter leidet. Die Querschnittsfläche des Schlüsselschafts kann durch konzentrisch zur Geraden liegende Linien und die Gerade schneidende Strahlen in Felder unterteilt werden. Durch Weglassen einiger Felder wird dann das Schlüsselschaftprofil bestimmt, und zwar in der Weise, daß die Bodenflächen der Nuten konzentrisch zum Mittelpunkt liegen, während die Seitenwände von Strahlenabschnitten gebildet sind.As a result of such a configuration, a large number of profile variations can be implemented without the clarity suffering as a result. The cross-sectional area of the key shank can be divided into fields by lines concentric to the straight line and straight lines. The key shaft profile is then determined by omitting a few fields, in such a way that the bottom surfaces of the grooves are concentric with the center, while the side walls are formed by beam sections.

Zwecks Variation der Tiefe der Nuten und Winkelstellung der Seitenwände zueinander können die Strahlen in unterschiedlicher Winkelverteilung und die konzentrisch zur Geraden verlaufenden Kreislinien in unterschiedlichen Abstand zu der Geraden angeordnet wrden. Ein derart in Felder aufgeteilter Schlüsselquerschnitt erleichtert die Fertigung der verschiedensten Schlüsselprofile, insbesondere dann, wenn die Felder mit Zahlen versehen werden.In order to vary the depth of the grooves and the angular position of the side walls with respect to one another, the beams can have a different angular distribution and the circular lines concentric to the straight line in different distance from the straight line. A key cross-section divided into fields in this way facilitates the production of a wide variety of key profiles, in particular when the fields are provided with numbers.

Die Erfindungsaufgabe wird auch dadurch gelöst, daß die Seitenflächen der Nuten konzentrisch verlaufen zu einer im Schlüsselschaftquerschnitt verlaufenden Geraden und die Bodenflächen der Nuten zentral ausgerichtet sind auf diese Gerade. Auf diese Weise ist es ebenfalls möglich, durch entsprechende Unterteilung des Schlüsselschaftquerschnitts durch Strahlen und konzentrisch zueinander liegende Kreislinien in Felder aufzuteilen und bei der Fertigung des Schlüsselprofils durch Weglassen einiger Felder die entsprechenden Nuten und Rippen zu erzeugen, wobei dann die Bodenflächen der Nuten auf den durch die Gerade laufenden Strahlen liegen, während die Seitenwände von den konzentrisch verlaufenden Bogenlinien gebildet werden. Es besteht die Möglichkeit, den Schlüssel im Querschnitt so zu profilieren, daß sowohl die Bodenflächen der Nuten konzentrisch zur Geraden verlaufen als auch auf Strahlenabschnitten liegen, was die Anzahl der möglichen Schlüsselquerschnittsprofile erhöht.The object of the invention is also achieved in that the side surfaces of the grooves are concentric with a straight line running in the key shank cross section and the bottom surfaces of the grooves are centrally aligned with this straight line. In this way, it is also possible to divide the key shank cross-section into rays and concentric circular lines into fields, and to produce the corresponding grooves and ribs during the production of the key profile by omitting some fields, with the bottom surfaces of the grooves on the through the straight rays lie, while the side walls are formed by the concentric arc lines. It is possible to profile the key in cross-section so that both the bottom surfaces of the grooves are concentric to the straight line and lie on beam sections, which increases the number of possible key cross-sectional profiles.

Eine weitere Erhöhung der möglichen Verschiedenheiten läßt sich dadurch erzielen, mehrere übereinander angeordnete zentrale Geraden vorzusehen. Die durch diese verlaufenden Strahlen und die konzentrisch ausgerichteten Bogenlinien gestatten eine noch feinere Abstufung des Schlüsselschaftquerschnitts.A further increase in the possible differences can be achieved by providing a plurality of central straight lines arranged one above the other. The rays running through these and the concentrically aligned arc lines allow an even finer gradation of the key shaft cross-section.

Eine Variation besteht hierbei darin, daß die Geraden in Querrichtung seitenversetzt zueinander liegen.A variation here is that the straight lines are laterally offset from one another in the transverse direction.

Nachstehend werden drei Ausführungsbeispiele der Erfindung anhand der Fig. 1-5 erläutert. Es zeigt

  • Fig. 1 eine Ansicht eines Schlüssels gemäß der ersten Ausführungsform im Schlüsselschaftbereich, und zwar in vergrößerter Darstellung,
  • Fig. 2 in stark vergrößerter Darstellung einen Querschnitt durch den Schlüsselschaft, welcher Schlüssel als übergeordneter Schlüssel ausgebildet ist,
  • Fig. 3 einen Querschnitt durch einen abweichend gestalteten, untergeordneten Schlüssel,
  • Fig. 4 einen Querschnitt durch einen Schlüssel gemäß der zweiten Ausführungsform, wobei zwei zentrale Geraden übereinander angeordnet sind und
  • Fig. 5 die dritte Ausführungsform des Schlüssels im Querschnitt, wobei drei zentrale Geraden in Querrichtung seitenversetzt zueinander liegen.
Three exemplary embodiments of the invention are explained below with reference to FIGS. 1-5. It shows
  • 1 is a view of a key according to the first embodiment in the key shaft area, in an enlarged view,
  • 2 in a greatly enlarged illustration a cross section through the key shaft, which key is designed as a superordinate key,
  • 3 shows a cross section through a differently designed, subordinate key,
  • Fig. 4 shows a cross section through a key according to the second embodiment, wherein two central straight lines are arranged one above the other and
  • Fig. 5 shows the third embodiment of the key in cross section, with three central straight lines laterally offset from one another in the transverse direction.

Der in Fig. 1 teilweise dargestellte Schlüssel 1 besitzt einen von der Schlüsselreide ausgehenden Schlüsselschaft 2. Die Schlüsselspitze 3 ist dachförmig gestaltet, um das Einführen des Schlüsselschaftes in einen Schlüsselkanal eines Schließzylinders und-das Einordnen der Stiftzuhaltungen zu ermöglichen. Der Schlüsselspitze 3 sind an der einen Schmalkante 4 Schließkerben 5 unterschiedlicher Tiefe nachgeordnet. Die der Schmalkante 4 gegenüberliegende Schmalkante 6 des Schlüsselschafts 2 verläuft, wie aus dem Querschnittsprofil ersichtlich, gerundet, und zwar ist sie der Krümmung eines Zylinderkerns normaler Abmessung angepaßt.The key 1 partially shown in FIG. 1 has a key shaft 2 extending from the key cord. The key tip 3 is designed in a roof shape in order to enable the key shaft to be inserted into a key channel of a locking cylinder and the pin tumblers to be arranged. The key tip 3 are arranged on one narrow edge 4 closing notches 5 of different depths. The narrow edge 6 of the key shank 2 opposite the narrow edge 4 is rounded, as can be seen from the cross-sectional profile, and in fact it is adapted to the curvature of a cylinder core of normal dimensions.

Bezüglich des in Fig. 1 und 2 dargestellten Schlüssels 1 handelt es sich um einen Hauptschlüssel, also einen übergeordneten Schlüssel. Mittig des Schlüsselschaftquerschnitts gemäß Fig. 2 verläuft eine Gerade 7. Konzentrisch zu dieser sind Kreislinien in gleichmäßigem Abstand angeordnet. Ferner gehen durch den Mittelpunkt in gleicher Winkelverteilung angeordnete Strahlen, wodurch der gesamte Schlüsselquerschnitt in Felder aufgeteilt wird. Durch Fortlassen einiger Felder wird das in Fig. 2 veranschaulichte Schlüsselschaftquerschnittsprofil erzeugt. Es entstehen hierdurch an den Schlüsselbreitseiten 8 und 9 angeordnete Nuten 10, 11, 12, 13, 14, 15 und 16 und entsprechende den Nuten benachbarte Rippen.With regard to the key 1 shown in FIGS. 1 and 2, it is a master key, that is to say a superordinate key. A runs in the middle of the key shaft cross-section according to FIG Just 7. Concentric to this are circular lines arranged at an even distance. Furthermore, rays arranged in the same angular distribution pass through the center, as a result of which the entire key cross section is divided into fields. The key shaft cross-sectional profile illustrated in FIG. 2 is generated by omitting some fields. This results in grooves 10, 11, 12, 13, 14, 15 and 16 arranged on the key broad sides 8 and 9 and corresponding ribs adjacent to the grooves.

Bezüglich der Nuten 11, 15 handelt es sich um solche, bei denen die Seitenwände 11' bzw. 15' auf die zentrale im Schlüsselschaftquerschnitt verlaufende Gerade 7 ausgerichtet sind. Das bedeutet, daß sich diese Seitenwände auf einem entsprechenden Strahtenabschnitt erstrecken, während die konvex gebogenen Bodenflächen 11", 15" konzentrisch zur Geraden 7 liegen, sich also auf einem Bogenabschnitt eines entsprechenden konzentrischen Kreises befinden.The grooves 11, 15 are those in which the side walls 11 'and 15' are aligned with the central straight line 7 running in the key shank cross section. This means that these side walls extend on a corresponding beam section, while the convexly curved bottom surfaces 11 ", 15" are concentric to the straight line 7, that is to say they are located on an arc section of a corresponding concentric circle.

Bei den anderen Nuten 10, 12, 13, 14, 16 verlaufen die Seitenwände 10',12', 13', 14', 16' konzentrisch zur zentralen Geraden 7. Sie befinden sich auf entsprechenden Kreisbogenabschnitten der konzentrisch zur Geraden 7 liegenden Kreise. Die Bodenflächen 10", 12", 13", 1411 und 16" sind dagegen zentral ausgerichtet auf diese Gerade 7. Sie stellen dadurch einen Strahlenabschnitt dar.In the case of the other grooves 10, 12, 13, 14, 16, the side walls 10 ', 12', 13 ', 14', 16 'run concentrically to the central straight line 7. They are located on corresponding arc sections of the circles lying concentrically to the straight line 7. The bottom surfaces 10 ", 12", 13 ", 1411 and 16", on the other hand, are centrally aligned with this straight line 7.

Das Schlüsselquerschnittsprofil läßt sich auf diese Weise mannigfaltig variieren, und zwar durch Fortlassen entsprechender durch die Strahlen und Kreisbögen gebildeter Felder.The key cross-sectional profile can be varied in many ways in this way, specifically by omitting corresponding fields formed by the rays and arcs.

Der in Fig. 3 veranschaulichte untergeordnete Schlüssel 17 ist so gestaltet, daß die Nuten 10, 14, 15 denjenigen des Schlüssels 1 entsprechen. Abweichend dagegen sind die Nuten 18, 19, 20, 21 querschnittskleiner gestaltet dadurch, daß strichpunktiert angedeutete Felder 18', 19', 20', 21' am Schlüsselprofil verbleiben, wodurch sich die Nuten 18, 19, 20, 21 von den entsprechenden Nuten 11, 12, 13, 16 des übergeordneten Schlüssels 1 unterscheiden. Daher läßt sich zwar ein übergeordneter Schlüssel 1 in den den untergeordneten Schlüssel 17 aufnehmenden untergeordneten Schließzylinder einstecken. Es ist jedoch nicht möglich, den untergeordneten Schlüssel 17 in das übergeordnete Schloß einzustecken wegen der anderen Querschnittsprofilierung des Schlüsselkanals. Die in Fig. 2 veranschaulichte Anzahl der Strahlen kann vergrößert oder verringert werden. Auch besteht die Möglichkeit, den Abstand der konzentrisch zur Geraden liegenden Kreise zu variieren.The subordinate key 17 illustrated in FIG. 3 is designed so that the grooves 10, 14, 15 correspond to those of the key 1. In contrast to this, the grooves 18, 19, 20, 21 are designed to be smaller in cross section in that fields 18 ', 19', 20 ', 21' indicated by dash-dotted lines remain on the key profile, as a result of which the grooves 18, 19, 20, 21 differ from the corresponding grooves 11, 12, 13, 16 of the parent key 1. Therefore, a higher-level key 1 can be inserted into the lower-level locking cylinder receiving the lower-level key 17. However, it is not possible to insert the subordinate key 17 into the superordinate lock because of the different cross-sectional profile of the key channel. The number of beams illustrated in FIG. 2 can be increased or decreased. There is also the possibility of varying the distance of the circles lying concentrically to the straight line.

Der in Fig. 4 veranschaulichte Schlüssel 22 besitzt im Schlüsselschaftquerschnitt zwei übereinander angeordnete zentrale Geraden 23 und 24. Konzentrisch zu diesen sind Kreise vorgesehen. Ferner laufen durch die Geraden 23, 24 in gleicher Winkelverteilung angeordnete Strahlen, wodurch der Schlüsselschaftquerschnitt in einzelne Felder aufgeteilt wird. Durch Fortlassen entsprechender Felder werden an den Schlüsselbreitseiten Nuten 25, 26, 27, 28, 29 und 30 geformt. Die Seitenwände dieser Nuten verlaufen entweder zentral auf die Geraden 23, 24 oder konzentrisch zu diesen, während die Bodenflächen der Nuten entweder zentral auf die Geraden gerichtet sind oder konzentrisch zu diesen liegen. Die an der Nut 29 auftretende Hinterschneidung kann dann entfallen, wenn der durch die beiden äußeren, einander tangierenden Kreise entstehende, der Nut 29 benachbarte Zwickel 29' Teil der Nut 29 wird. Auch faßt sich eine Hinterschneidung an der Nut 26 beseitigen, und zwar durch Schneiden zweier Kreise unter Bildung eines Zwickels 26', der dann von der Nut 26 erfaßt wird.The key 22 illustrated in FIG. 4 has two central straight lines 23 and 24 arranged one above the other in the key shaft cross section. Circles are provided concentrically to these. In addition, rays arranged in the same angular distribution run through the straight lines 23, 24, as a result of which the key shaft cross section is divided into individual fields. By omitting corresponding fields, grooves 25, 26, 27, 28, 29 and 30 are formed on the key broad sides. The side walls of these grooves either run centrally on the straight lines 23, 24 or concentrically to these, while the bottom surfaces of the grooves are either directed centrally to the straight lines or are concentric to these. The undercut occurring on the groove 29 can then be omitted if the gusset 29 ′ formed by the two outer, tangent circles and adjacent to the groove 29 becomes part of the groove 29. It is also possible to eliminate an undercut on the groove 26 by cutting two circles to form a gusset 26 'which is then gripped by the groove 26.

Der in Fig. 5 veranschaulichte Schlüssel 31 besitzt im Schlüsselschaftquerschnitt drei übereinander angeordnete zentrale Geraden 32, 33 und 34, wobei die Geraden 32, 34 übereinander auf Höhe der einen Schlüsselbreitseite 35 angeordnet sind. Die Gerade 33 dagegen erstreckt sich mittig zwischen den beiden anderen Geraden 32, 34, jedoch auf der anderen Schlüsselbreitseite 36. Konzentrisch zu den Geraden 32, 33, 34 befinden sich Kreisbögen. Ferner gehen von den Geraden 32, 33, 34 Strahlen aus, die den gesamten Schlüsselquerschnitt in einzelne Felder unterteilen. in vorliegendem Falle werden durch Weglassen entsprechender Felder Nuten 37, 38, 39, 40 und 41 erzeugt. Deren Bodenflächen und Seitenwände liegen auf den Strahlenabschnitten oder Kreisbogenabschnitten. Die bei der Nut 39 vorliegende Hinterschneidung ist vermeidbar, wenn um die Gerade 34 ein größerer Kreis geschlagen wird, der den Boden der Nut 39 schneidet. Es entsteht dadurch ein Zwickel 39', um welchen die Nut 39 kleiner wird.The key 31 illustrated in FIG. 5 has three central straight lines 32, 33 and 34 arranged one above the other in the key shaft cross section, the straight lines 32, 34 being arranged one above the other at the level of one key broadside 35. The straight line 33, however, extends in the middle between the two other straight lines 32, 34, but on the other key broadside 36. Circular arcs are concentric to the straight lines 32, 33, 34. Furthermore, straight lines 32, 33, 34 emit rays which subdivide the entire key cross section into individual fields. in the present case, grooves 37, 38, 39, 40 and 41 are produced by omitting corresponding fields. Their bottom surfaces and side walls lie on the beam sections or circular arc sections. The undercut present in the groove 39 can be avoided if a larger circle is cut around the straight line 34 and intersects the bottom of the groove 39. This creates a gusset 39 'around which the groove 39 becomes smaller.

Weitere Variationen sind möglich. Es liegt aber in jedem Falle ein in Felder zu unterteilender Schlüsselschaftquerschnitt vor, der die Schließanlagen-Profilvariation begünstigt.Other variations are possible. In any case, there is a key shaft cross-section that can be divided into fields, which favors the locking system profile variation.

Alle in der Beschreibung erwähnten und in der Zeichnung dargestellten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
