Description

Die Erfindung betrifft ein Verfahren gemäß Gattungsbegriff des Anspruchs 1, eines System von Flachschlüsseln gemäß Gattungsbegriff des Anspruchs 2 und eine Schließanlage gemäß Gattungsbegriff des Anspruchs 10. Das erfindungsgemäße Verfahren, das erfindungsgemäße System von Flachschlüsseln und die erfindungsgemäße Schließanlage betrifft eine Profilvariation.The invention relates to a method according to the preamble of claim 1, a system of flat keys according to the preamble of claim 2 and a locking system according to the preamble of claim 10. The inventive method, the inventive system of flat keys and the locking system according to the invention relates to a profile variation.

Die Profilvariation erfüllt bekannterweise zunächst zwei Aufgaben, indem sie einerseits die lagengerechte Bewegung des Schlüssels im Schlüsselkanal gewährleistet und andererseits darüber bestimmt, ob der Schlüssel in ein bestimmtes Schloss eingeführt oder nicht eingeführt werden kann. Wesentlich ist die mit der Profilvariationsregel geschaffene Möglichkeit, Schliessanlagen mit mehreren Hierarchieebenen zu konzipieren. Die Profilvariationsregel ermöglicht es darüber hinaus, verschiedene Schliessanlagen so aufeinander abzustimmen, dass Überschliessungen weitestgehend ausgeschlossen sind. Eine Profilvariation der in Rede stehenden Art ist bekannt aus der DE 33 14 417 C2 , wobei konzentrisch zu den Zentrumsgeraden Kreise gelegt sind. Ferner werden die Zentrumsgeraden von strahlenartig angeordneten Linien gekreuzt. Es wird dadurch ein Kreis-Strahlensystem geschaffen, welches Grundlage einer Profilvariation ist. Die Variierungsnuten sind so beschaffen, dass sie in Richtung der Zentrumsgeraden konvergieren, wobei der Nutengrund einen Kreislinien-Abschnitt darstellt.The profile variation is known to perform two tasks initially, on the one hand ensures the positional movement of the key in the key channel and on the other determined whether the key can be inserted into a particular lock or not introduced. What is essential is the possibility provided by the profile variation rule of designing locking systems with several hierarchical levels. In addition, the profile variation rule makes it possible to match different locking systems in such a way that overlaps are largely excluded. A profile variation of the type in question is known from the DE 33 14 417 C2 , where circles are laid concentrically to the center line. Furthermore, the center lines are crossed by rays arranged in a line. It is created by a circular beam system, which is the basis of a profile variation. The variation grooves are arranged to converge toward the center line, the groove bottom forming a circular line section.

Aus den AT 004 291 U1 , EP 1217151 A1 und US 4,368,629 sind Profilsysteme für Flachschlüssel bekannt, bei denen die Schlüsselbreitseite Variationsprofilelemente in Form von Kerben mit rechtwinklig zueinander stehenden Flanken aufweisen. Zur Erzielung einer Schliesshierarchie werden die Kerben mit trapezförmigen Feldern teilweise gefüllt.From the AT 004 291 U1 . EP 1217151 A1 and US 4,368,629 Profile systems for flat keys are known in which the key broadside have variation profile elements in the form of notches with mutually perpendicular edges. To achieve a closing hierarchy, the notches are partially filled with trapezoidal fields.

Die AT 005 395 U1 beschreibt ebenfalls ein Profilsystem zur Querschnittsausbildung von Flachschlüsseln. Auch hier erfolgt die Profilvariation durch Auffüllen eines durch eine Kerbe gebildeten Profilelementes mit Feldern.The AT 005 395 U1 also describes a profile system for the cross-sectional formation of flat keys. Again, the profile variation is done by filling a profile element formed by a notch with fields.

Aus der DE 3314417 A1 ist ein Schlüssel für einen Schließzylinder bekannt, bei dem die Seitenwände der Nuten auf eine im Schlüsselquerschnitt verlaufende Gerade ausgerichtet sind.From the DE 3314417 A1 is a key for a lock cylinder is known in which the side walls of the grooves are aligned with a key cross-section extending straight.

Aus der DE 4304604 A1 ist ein aus Schließzylindern und Schlüsseln bestehendes Schließanlagensystem bekannt, bei dem zwischen den Rippen des Schlüsselkanals und den zugeordneten Flanken der Nuten der Schlüsselbreitseite Flanken verbleiben.From the DE 4304604 A1 is a locking system consisting of lock cylinders and keys known in which remain between the ribs of the keyway and the associated edges of the grooves of the key broadside flanks.

Der Erfindung liegt die Aufgabe zugrunde, bei einer gattungsgemäßen Ausgestaltung in einfacher Weise eine Profilvariation mit einer hohen Möglichkeit an Verschiedenheiten zu schaffen.The invention has for its object to provide in a generic embodiment in a simple manner a profile variation with a high possibility of differences.

Diese Aufgabe ist durch das im Anspruch 1 angegebene Verfahren, das im Anspruch 2 angegebene System von Flachschlüsseln und die im Anspruch 10 angegebene Schließanlage gelöst, wobei zunächst und im Wesentlichen bei einer Profilvariation darauf abgestellt ist, dass bezogen auf eine Querschnittsdarstellung zwei sich schneidende Flanken einer Variierungsnut auf Geraden verlaufen, die durch die Endpunkte eines die Zentrumsgerade mit dem Abstandsmaß umgebenden Halbkreisbogens verlaufen und sich in einem auf dem Halbkreisbogen liegenden Punkt schneiden. Zufolge derartiger Ausgestaltung lässt sich eine Vielzahl von Verschiedenheiten der Variierungsnuten erreichen. Der Öffnungswinkel der Flanken einer Variierungsnut beträgt stets 90° und geht vom Halbkreisbogen aus. Der spitz zulaufende Nutengrund kann an jeder Stelle des Halbkreisbogens ansetzen, wobei die Flanken der Variierungsnut in Gestalt von Geraden durch die Endpunkte des Halbkreisbogens um die Zentrumsgerade verlaufen. Stets bleibt der Öffnungswinkel rechtwinklig. Die Erfindung macht sich hierbei die Erkenntnis des "Satzes des Thales" zunutze, der folgendes ausdrückt: Der geometrische Ort der Scheitelpunkte aller rechten Winkel, deren Schenkel durch zwei feste Punkte gehen, ist der Kreis über der Strecke als Durchmesser. Es können demgemäß Einsparungen hinsichtlich der die Nuten erzeugenden Werkzeuge erzielt werden. Die unterschiedliche Form der Variierungsnuten erreicht man lediglich durch entsprechende Ausrichtung des Werkzeuges zur Schlüsselbreitseite. Eine zusätzliche Verschleierung der Variierungsnuten lässt sich dadurch erreichen, dass die Endpunkte in der Schlüsselbreitseitenebene oder parallel zu dieser versetzt liegen. Der parallele Versatz kann entweder schlüsseleinwärts oder schlüsselauswärts gerichtet sein. Ferner ist verhindert, durch Abfeilen der Schlüsselbreitfläche einen übergeordneten Schlüssel zu erhalten. Zu diesem Zweck ist erfindungsgemäß vorgesehen, dass sich die Radien der Halbkreisbögen von zumindest zwei sich gegenüberliegenden Variierungsnuten parazentrisch überlappen. Im Detail ist dabei so vorgegangen, dass eine zur Schlüsselbreitseitenebene parallel verlaufende Ebene von mindestens zwei sich gegenüberliegenden Nuten geschnitten wird. Weiterhin kann zur Erhöhung der Verschiedenheiten die Maßnahme getroffen sein, dass die Halbkreisbögen verschiedener Variierungsnuten unterschiedlich großen Durchmesser haben. Dennoch ist der Einsatz gleichgestalteter Werkzeuge möglich. Zwecks Schaffung übergeordneter Schlüssel, welche sowohl die die untergeordneten Einzelschließzylinder als auch den übergeordneten Schließzylinder schließen, ist eine geradlinige Anzahl an Flanken einer Variierungsnut vorgesehen, von denen sich jeweils zwei rechtwinklig in einem auf dem Halbkreisbogen liegenden Schnittpunkt schneiden. Das bedeutet, dass in jeder Halbkreisfläche überlagernd versetzt zueinander angeordnete rechtwinklige Dreiecke vorgesehen sind, welche die Gestalt des Nutgrundes der Profilnut bestimmen. So kann sich eine solche Figuration ergeben, bei welcher sich die Flanken einer Variierungsnut in mindestens einem in der Halbkreisfläche liegenden Kamm stumpfwinklig schneiden. Sodann besteht die Möglichkeit, zwecks Erhöhung der Verschiedenheiten hinsichtlich der Profilvariation sich teilüberlappende Halbkreisbögen vorzusehen, innerhalb welcher die sich schneidenden Flanken der Variierungsnuten verlaufen. Aufgrund der erfindungsgemäßen Ausgestaltung ist mit Vorteil der Einsatz in Schließanlagen mit jeweils einer Anzahl von Schließzylindern mit voneinander abweichenden Schließungen und dazu passenden Schlüsseln ermöglicht. Mindestens ein übergeordneter Schlüssel hat dabei eine Flankengestaltung derart, dass sich die Flanken einer Variierungsnut in mindestens einem in der Halbkreisfläche liegenden Kamm stumpfwinklig schneiden. Praktisch ist eine solche Gestaltung möglich, dass bei einem Schlüssel, insbesondere einem Generalhauptschlüssel, das Querschnittsprofil mindestens einer Variierungsnut als Polygon sich der Halbkreisfläche annähert. Einsetzbar ist der Erfindungsgedanke bei Flachschlüsseln mit Schlüsselreide und Schlüsselschaft, welcher Schließkerben oder dergleichen zum Einordnen von Zuhaltungsstiften und Variierungsnuten aufweist, welche zur Bestimmung einer Schließhierarchie unterschiedlich querschnittsprofiliert sind. Zur jeweiligen Individualisierung des Schlüssels zu einer Schließanlage ist das Querschnittsprofil entsprechend profiliert. Im Wesentlichen sieht dies so aus, dass die Nuten der Schlüsselbreitseite mit Rippen des Schlüsselkanals korrespondieren. Die Rippen sind also Bestandteil eines Schließzylinders. Daher bilden die Rippen das Reziprokprofil eines der vorhergehenden Ansprüche aus.This object is achieved by the method specified in claim 1, the specified in claim 2 system of flat keys and the locking system specified in claim 10, wherein initially and essentially is aimed at a profile variation that based on a cross-sectional view two intersecting edges of a variation groove on straight lines passing through the end points of a semicircle arc surrounding the center just with the distance measure and intersecting in a point lying on the semicircular arc. According to such a configuration, a plurality of differences of the variation grooves can be achieved. The opening angle of the flanks of a variation groove is always 90 ° and starts from the semicircular arc. The tapered groove bottom can begin at any point of the semicircular arc, wherein the flanks of the variation groove in the form of straight lines through the end points of the semicircular arc run around the center straight. The opening angle always remains rectangular. The invention makes use of the knowledge of the "Theorem of Thales" which expresses the following: The geometric location of the vertices of all right angles, the legs of which pass through two fixed points, is the circle over the distance as a diameter. Accordingly, savings can be achieved in terms of the grooves generating tools. The different shape of the V-grooves can be achieved only by appropriate alignment of the tool to the key broadside. An additional concealment of the V-grooves can be achieved by having the endpoints in the key width side plane or offset parallel to this. The parallel offset may be either in-key or out-of-key. Furthermore, it is prevented by filing the key area to obtain a parent key. For this purpose, the invention provides that the radii of the semicircular arcs overlap paracentrically by at least two opposing variation grooves. In detail, the procedure is such that a plane extending parallel to the key width side plane is cut by at least two opposing grooves. Furthermore, to increase the differences, the measure can be taken that the semicircular arches of different Variation grooves have different diameter. Nevertheless, the use of the same shape tools is possible. For the purpose of creating higher-level keys, which close both the subordinate individual closing cylinder and the parent lock cylinder, a rectilinear number of edges of a Variierungsnut is provided, of which each intersect two at right angles in a lying on the semicircular intersection point. This means that in each semicircular surface overlapping staggered perpendicular triangles are provided which determine the shape of the groove bottom of the profile groove. Thus, such a figuration may result in which the flanks of a variation groove intersect at an obtuse angle in at least one comb lying in the semicircular surface. It is then possible, in order to increase the differences in the profile variation, to provide partially overlapping semicircular arcs within which the intersecting flanks of the variation grooves run. Due to the configuration of the invention is advantageously the use in locking systems, each with a number of lock cylinders with divergent locks and matching keys allows. At least one higher-order key has a flank configuration such that the flanks of a variation groove lie in at least one in the semicircular surface Cut the comb at an obtuse angle. Practically, such a design is possible that in a key, in particular a general master key, the cross-sectional profile of at least one variation groove as a polygon approaches the semicircular surface. The concept of the invention can be used in the case of flat keys with a key ridge and a key shank which has closing notches or the like for arranging tumbler pins and variation grooves, which are differently cross-sectional profiled to determine a locking hierarchy. For the individualization of the key to a locking system, the cross-sectional profile is profiled accordingly. In essence, this looks like that the grooves of the key broadside correspond to ribs of the keyway. The ribs are thus part of a lock cylinder. Therefore, the ribs form the reciprocal profile of one of the preceding claims.

Figur 1 zeigt einen als Rohling gestalteten Flachschlüssel 1, bestehend aus einem Schlüsselschaft 2 und einer Schlüsselreide 3. Der Rücken 4 des Schlüsselschaftes verläuft auf einem Kreisbogen, im Querschnitt gesehen, wobei die Krümmung der Umfangslinie des Zylinderkerns eines nicht veranschaulichten Schließzylinders angepasst ist. Dem Rücken 4 gegenüber liegt die Brust 5. Von dieser Seite her werden die nicht veranschaulichten Schließkerben eingeschnitten, welche in bekannter Weise zur Einordnung von schließzylinderseitigen Zuhaltungsstiften dienen, so dass bei ordnungsgemäß gestaltetem Schlüssel die Zuhaltungen so eingeordnet werden, dass ein Drehen des Zylinderkerns ermöglicht ist. FIG. 1 shows a designed as a blank flat key 1, consisting of a key shank 2 and a key grain 3. The back 4 of the key shank extends on a circular arc, seen in cross section, wherein the curvature of the circumferential line of the cylinder core of a not illustrated lock cylinder is adjusted. The chest 4 is opposite the back 4. From this side, the not illustrated closing notches are cut, which serve in a known manner for the classification of lock cylinder side tumbler pins, so that when properly designed key tumblers are arranged so that a rotation of the cylinder core is possible ,

Von den Schlüsselbreitseiten 6 gehen Variierungsnuten 7 aus. In diese greifen beim Einschieben des Schlüssels in den Schlüsselkanal des Schließzylinders hineinragende Rippen ein, die entsprechend querschnittsprofiliert sind.From the key broadsides 6 go Variation grooves 7. In this engage in the insertion of the key in the keyway of the lock cylinder protruding ribs, which are correspondingly cross-sectional profiled.

Die in Fig. 2 dargestellten Grundprofile zeigen Möglichkeiten der Anordnung von Zentrumsgeraden Z in Bezug zu den Schlüsselbreitseiten 6. Gemäß Fig. 2a weist die linke Schlüsselbreitseite 6 drei übereinander angeordnete Zentrumsgeraden Z auf. Mit Abstand zu diesen verlaufen Halbkreisbögen B. Auch die rechte Schlüsselbreitseite 6 besitzt drei Zentrumslinien Z mit diesen zugeordneten Halbkreisbögen B. Mit strichpunktierten Linien sind innerhalb der Halbkreisflächen mehrere Dreiecke strichpunktiert angedeutet, deren Basis der Durchmesser des Halbkreisbogens ist, während die Katheten sich in einem auf dem Halbkreisbogen B liegenden Punkt schneiden. Hierdurch hat jedes Dreieck oberhalb seines Durchmessers einen rechten Winkel. Auf diese Weise lassen sich die verschiedensten Profilvariationen von Variierungsnuten 7 erzeugen.In the Fig. 2 illustrated basic profiles show ways of arranging center line Z with respect to the key broadsides 6. According to Fig. 2a has the left key broadside 6 three superimposed center line Z on. At a distance to these run semicircular arcs B. The right key broadside 6 has three center lines Z associated with these Semicircular arches B. With dotted lines, several triangles are indicated by dash-dotted lines within the semicircular surfaces, whose base is the diameter of the semicircular arc, while the cathets intersect in a point lying on the semicircular arc B. As a result, each triangle has a right angle above its diameter. In this way, the most varied profile variations of Variation grooves 7 can be generated.

Sieht man eine symmetrische Anordnung der Variierungsnuten zur Schlüsselquermittelebene vor, so könnte auf dieser Basis ein Wendeschlüssel realisiert werden, der dann jedoch die Schließkerben auf seinen Schlüsselbreitseiten ausbildet. Gemäß Fig. 2a sind auf jeder Schlüsselbreitseite 6 zwei Halbkreisbögen B in Nebeneinanderlage veranschaulicht, welche die Schlüssellängsmittelebene x-x tangieren. Der verbleibende Halbkreisbogen B hat dagegen einen Radius, welcher kleiner ist als die halbe Schlüsseldicke.If one looks at a symmetrical arrangement of the variation grooves for the key transverse median plane, then a reversible key could be realized on this basis, which then however forms the closing notches on its key broadsides. According to Fig. 2a are illustrated on each key broadside 6 two half-circular arcs B in juxtaposition, which affect the key longitudinal plane xx. By contrast, the remaining semicircular arc B has a radius which is smaller than half the key thickness.

Gemäß Fig. 2b liegen auf jeder Schlüsselbreitseite 6 zwei in Schlüsseleinsteckrichtung verlaufende Zentrumsgeraden Z vor. Um diese verlaufen mit Abstandsmaß Halbkreisbögen B, welche die Schlüssellängsmittelebene x-x tangieren. Innerhalb der Halbkreisflächen sind strichpunktiert Möglichkeiten der rechtwinkligen Dreiecke angegeben, deren Flanken zur Bildung der Variierungsnuten 7 dienen können. Auch bei dieser Version besteht die Möglichkeit, eine symmetrische Anordnung zur Quermittelebene des Schlüsselschaftes zu schaffen, so dass bei entsprechender Gestaltung des Schließzylinders und des Schlüsselschaftes der Einsatz als Wendeschlüssel möglich ist, welcher dann auf seinen Schlüsselbreitseiten die Schließvertiefungen ausbildet.According to Fig. 2b are on each Schlüsselbreitseite 6 two running in Schlüsseleinsteckrichtung center line Z before. These run with distance measure semicircular arches B, which affect the key longitudinal center plane xx. Within the semicircular areas, options of the right-angled triangles are indicated by dashed lines, whose flanks can serve to form the variation grooves 7. Also in this version, it is possible to create a symmetrical arrangement to the transverse center plane of the key shank, so that with appropriate design of the lock cylinder and the key shank the use as a reversible key is possible, which then forms on its key broadsides the closing recesses.

In Fig. 3 sind mögliche Profilvariationen an Einzelschlüsseln aufgezeigt. Im Detail zeigt der Einzelschlüssel gemäß Fig. 3a ein solches Querschnittsprofil, bei welchem auf der linken Schlüsselbreitseite drei Variierungsnuten 7 vorgesehen sind. Deren Zentrumslinien Z liegen auf Höhe der Schlüsselbreitseite 6. So zeigt die obere Variierungsnut 7, dass zwei sich schneidende Flanken 7', 7" auf Geraden verlaufen. Diese gehen durch die Endpunkte 8 des Halbkreisbogens B. Die Geraden schneiden sich in einem auf dem Halbkreisbogen B liegenden Punkt P. Der eingeschlossene Winkel α ist somit, wie vorher ausgeführt wurde, ein rechter Winkel. Gemäß Fig. 3a ist eine solche Gestaltung getroffen, dass die Flanken 7" länger sind als die Flanken 7'.In Fig. 3 possible profile variations on individual keys are shown. In detail, the single key shows according to Fig. 3a such a cross-sectional profile, at which are provided on the left key broadside three Variierungsnuten 7. Their center lines Z are at the level of the key broadside 6. Thus, the upper variation groove 7 shows that two intersecting flanks 7 ', 7 "run on straight lines passing through the end points 8 of the semicircular arc B. The straight lines intersect in one on the semicircular arc The included angle α is therefore a right angle as previously stated Fig. 3a is such a design that the flanks 7 "are longer than the flanks 7 '.

Eine ähnliche Gestaltung liegt bezüglich der unteren Variierungsnut 7 auf der linken Schlüsselbreitseite 6 vor. Der Unterschied besteht darin, dass dort der Halbkreisbogen B einen geringeren Durchmesser hat, dessen Zentrumsgerade Z auch auf der Schlüsselbreitseite 6 liegt. Die mittlere Variierungsnut 7 ist ausschließlich in Form eines Halbkreisbogens gestaltet. Dies trifft auch auf die obere, auf der rechten Schlüsselbreitseite 6 angeordnete Variierungsnut 7 in Fig. 3a zu. Die darunter angeordneten Profilierungsnuten 7 besitzen die Form rechter Winkel mit Flanken 7', 7", welche sich in dem Halbkreisbogen B in den Punkten P schneiden. Ferner verlaufen die Zentrumsgeraden Z auf Höhe der Schlüsselbreitseite 6.A similar design is with respect to the lower Variierungsnut 7 on the left key broadside 6 before. The difference is that there the semicircular arc B has a smaller diameter, the center straight Z is also on the key broadside 6. The middle variation groove 7 is designed exclusively in the form of a semicircular arc. This also applies to the upper, arranged on the right key broadside 6 Variation 7 in Fig. 3a to. The profiling grooves 7 arranged underneath have the shape of right angles with flanks 7 ', 7 ", which intersect in the semicircular arc B at the points P. Furthermore, the center straight lines Z extend at the level of the broad-wedge side 6.

Die Fig. 3b und 3c veranschaulichen weitere Möglichkeiten zur Schaffung der Profilvariationen bezüglich der Variierungsnuten 7, so dass dort äquivalente Teile gleiche Bezugsziffern aufweisen.The Fig. 3b and 3c illustrate further possibilities for creating the profile variations with respect to the Variation grooves 7, so that there equivalent parts have the same reference numerals.

Gemäß Fig. 4 sind die Schlüssel4b und 4c Einzelschlüssel, die nach der vorbeschriebenen Gesetzmäßigkeit jeweils drei Variierungsnuten 7 auf jeder Schlüsselbreitseite 6 ausbilden. Der übergeordnete Schlüssel gemäß Fig. 4a ist so gestaltet, dass mittels diesem auch die Einzelzylinder schließbar sind, die von den Einzelschlüsseln 4b und 4c betätigt werden können. Zu diesem Zweck weist jede Variierungsnut des übergeordneten Schlüssels gemäß Fig. 4a eine geradlinige Anzahl an Flanken 7', 7" auf, von denen sich jeweils zwei rechtwinklig in einem auf dem Halbkreisbogen liegenden Schnittpunkt schneiden. Bei dem dargestellten Ausführungsbeispiel nach Fig. 4a erstrecken sich z. B. oberhalb des Durchmessers des oberen, auf der linken Schlüsselbreitseite angeordneten Halbkreisbogens B drei Dreiecke mit jeweils rechten Winkeln. Das Dreieck I entspricht der korrespondierenden Variierungsnut 7 des Einzelschlüssels nach Fig. 4b und das Dreieck II der zugehörigen Variierungsnut 7 des Einzelschlüssels nach Fig. 4c. Das Dreieck III hat kein Pendant zu den Einzelschlüsseln. Dementsprechend bildet dort die Rippe des übergeordneten Schließzylinders eine entsprechende Figuration aus, so dass die Einzelschlüssel gemäß Fig. 4b und 4c nicht in den Schlüsselkanal des übergeordneten Schließzylinders einführbar sind und somit ausgesperrt werden. Die weiteren Variierungsnuten 7 des übergeordneten Schlüssels sind entsprechend aufgebaut. Es wird daher nicht näher auf sie eingegangen. Bei Betrachtung der Variierungsnuten des übergeordneten Schlüssels nach Fig. 4a schneiden sich die Flanken 7', 7" benachbarter Dreiecke in mindestens einem in der Halbkreisfläche liegenden Kamm stumpfwinklig. Je mehr Einzelschließzylinder zu schließen sind, desto feiner kann der Kamm gestaltet sein. Das bedeutet, dass insbesondere bei einem Generalhauptschlüssel das Querschnittsprofil mindestens einer Variierungsnut als Polygon sich der Halbkreisfläche annähert. Grundsätzlich ist jedoch festzuhalten, dass die Rippen des Schlüsselkanals des Schließzylinders das Reziprokprofil der Variierungsnuten sind.According to Fig. 4 the keys 4b and 4c are individual keys which, according to the above-described law, each form three variation grooves 7 on each key broad side 6. The parent key according to Fig. 4a is designed so that by means of this, the individual cylinder can be closed, which can be operated by the individual keys 4b and 4c. To this end identifies each variation groove of the parent key Fig. 4a a rectilinear number of flanks 7 ', 7 ", of which in each case two intersect at right angles in an intersection lying on the semicircular arc Fig. 4a extend z. B. above the diameter of the upper, arranged on the left key broadside semicircle B three triangles each with right angles. The triangle I corresponds to the corresponding variation groove 7 of the single key after Fig. 4b and the triangle II of the associated Variierungsnut 7 of the single key after Fig. 4c , The triangle III has no counterpart to the single keys. Accordingly, there forms the rib of the parent lock cylinder a corresponding Figuration, so that the individual key according to Fig. 4b and 4c can not be inserted into the key channel of the parent lock cylinder and thus locked out. The further variation grooves 7 of the parent key are constructed accordingly. It is therefore not discussed in detail. Looking at the variation grooves of the parent key after Fig. 4a the flanks 7 ', 7 "of adjacent triangles intersect at least one obtuse angle in at least one comb located in the semicircular surface The more individual locking cylinders are to be closed, the finer the comb can be designed, which means that in particular for a general master key the cross-sectional profile of at least one variation groove In principle, however, it should be noted that the ribs of the keyway of the lock cylinder are the reciprocal profile of the variation grooves.

Der Einzelschlüssel nach Fig. 5a veranschaulicht auf der linken Schlüsselbreitseite eine derartige Profilvariation, dass sich benachbarte Halbkreisbögen B teilüberlappen. Deren Zentrumsgeraden Z liegen auf Höhe der Schlüsselbreitseite 6. Auf der gegenüberliegenden Schlüsselbreitseite sind die Halbkreisbögen B mit Abstand zueinander angeordnet, jedoch mit auf den Schlüsselbreitseiten liegenden Zentrumsgeraden Z. Gemäß Fig. 5a können solche Variierungsnuten 7 ausgebildet werden, welche eine sägezahnartige Struktur bilden. Das bedeutet, dass Flanken 7' benachbarter Variierungsnuten 7 parallel zueinander verlaufen.The single key after Fig. 5a illustrates on the left key broadside such a profile variation that adjacent semicircular arcs B partially overlap. Their center line Z are at the level of Schlüsselbreitseite 6. On the opposite key broadside the semicircular arcs B are arranged at a distance from each other, but with on the key broadsides lying center line Z. According to Fig. 5a it is possible to form such variation grooves 7 which form a sawtooth-like structure. This means that flanks 7 'of adjacent variation grooves 7 run parallel to one another.

Der Schlüssel gemäß Fig. 5b besitzt eine Profilvariation, bei welcher auf jeder Schlüsselbreitseite je eine Variierungsnut 7 so gestaltet ist, dass die Endpunkte 8 parallel versetzt zur Schlüsselbreitseite 6 liegen, und zwar in Einwärtsrichtung. Das bedeutet, dass dann die betreffenden Zentrumslinien Z' innerhalb des Querschnittsprofils des Schlüsselschaftes 2 liegen. Gemäß Fig. 5b handelt es sich auf der rechten Schlüsselbreitseite 6 um die mittlere Variierungsnut 7 und auf der gegenüberliegenden Schlüsselbreitseite um die untere Variierungsnut 7. Der Einwärtsversatz ist dabei mit y bezeichnet. Ferner ist der Durchmesser des auf der linken Seite unteren Halbkreisbogens B etwa halb so groß wie der Durchmesser des auf der gegenüberliegenden Schlüsselbreitseite liegenden Halbkreisbogens B. Aufgrund des Versatzes y und des Radius des mittleren Halbkreisbogens B, welcher Radius der halben Schlüsseldicke entspricht, überlappen sich die Radien der Halbkreisbögen B von zumindest zwei sich gegenüberliegenden Variierungsnuten 7. So ist es möglich, dass eine zur Schlüsselbreitseitenebene parallel verlaufende Ebene von mindestens zwei sich gegenüberliegenden Nuten 7 geschnitten wird. Im vorliegenden Fall sind es die der Quermittelebene des Schlüsselschaftes 2 benachbarten Nuten 7. Aufgrund dessen lässt sich durch Abfeilen der Schlüsselbreitseiten kein übergeordneter Schlüssel erzeugen, da dieser aufgrund der Parazentrizität auseinanderfallen würde. The key according to Fig. 5b has a profile variation, in which on each key broadside each a Variierungsnut 7 is designed so that the end points 8 are offset parallel to the key broadside 6, in the inward direction. This means that then the respective center lines Z 'are within the cross-sectional profile of the key shank 2. According to Fig. 5b it is on the right side of the key broadside 6 to the middle Variierungsnut 7 and on the opposite key broadside to the lower Variierungsnut 7. The inward offset is denoted by y. Further, the diameter of the lower semicircle arc B on the left side is about half the diameter of the semicircular arc B lying on the opposite wrench width side. Due to the offset y and the radius of the middle semicircle arc B, which radius corresponds to half the key thickness, the overlap Radii of the semicircular arches B of at least two opposing Variation grooves 7. Thus, it is possible that a plane extending parallel to the key width side plane of at least two opposing grooves 7 is cut. In the present case, it is the grooves 7 that are adjacent to the transverse center plane of the key shank 2. Because of this, it is not possible to generate a higher-order key by filing the key broadsheets, since this would fall apart due to the paracentricity.
