Definitions
- the invention relates to a lock and key system, especially for locking systems, and has set itself the task of being able to offer greater security against unlocking locks.
- the invention inversely proposes that the known assign the invariant basic profile to the area of the key face bearing the classification notches and to provide this with at least two profile designs (paracentric profile design) that cross the key center line and the variation or system profile in the key spine adjoining section
- the variation or system profile should have at least one over.
- the key side surfaces have protruding locking rib profile and the profile incisions of the invariant basic profile and the variation or system profile a rectangular cross section.
- FIG. 1 shows the prior art, from which the invention forms a departure.
- This state of the art represents a key 1 in which the basic profile 2 is assigned to the section adjacent to the key back 3 and the variation profile 4 is assigned to the section adjacent to the key face 5 provided with classification incisions.
- Possible profile variations are indicated in FIG. 1, and it goes without saying that the key channel in the region of the variation profile must have at least the opening indicated by dashed lines at 6 and, in the basic form, a straight-line opening.
- FIGS. 2 to 4 The invention shown in FIGS. 2 to 4 is characterized in that the invariant basic profile 7 is moved into the key section 5 containing the classification notches, while the system or variation profile 8 belongs to the section near the key back, which can extend to the key center part.
- FIG. 2 shows a superordinate key largely undressed from the variation profile
- FIGS. 3 and 4 show keys with indicated variation profile configurations. Both keys, however, have in common that in the lower section, namely that of the key chest 5, they carry a basic profile 7 which, as the exemplary embodiments show, consists of a pracentricity which exceeds the center line 9 at three points.
- the indicated key channel 10 in this section has a jagged course that largely prevents the use of probing tools.
- the other profile incisions 12 also have a rectangular cross section. After all, it is for security against the unauthorized opener. of the lock it is important that the key has at least one locking rib profile, ie a profile which projects beyond the key compartment side, so that reworking of the key could only be carried out by applying material. In the embodiments in Figures 2 to 4, 4 locking ribs are provided.

Abstract
Description
Die Erfindung betrifft ein Schloß-Schlüsselsystem, insbesondere für Verschlußanlagen, und hat sich die Aufgabe gestellt, eine größere Sicherheit gegen das Auftasten von Schlössern bieten zu können.The invention relates to a lock and key system, especially for locking systems, and has set itself the task of being able to offer greater security against unlocking locks.
Es sind bereits Systeme bekannt, bei denen das Variations- oder Anlagenprofil dem Schlüsselbrustbereich, also dem Bereich, der die Einordnungskerben trägt, zugeordnet ist, während der dem Schlüsselrücken angrenzende Abschnitt mit dem invarianten Grund- oder Führungsprofil ausgestattet ist. Der Nachteil dieser Zuordnungenvon Variations-und in invariantem Grundprofil ist darin zu sehen, daß der Schlüsselkanal gerade im Bereich der Zuhaltungen unter Einhaltung einer Mindestbreite und geradlinig begrenzt gehalten werden muß, was Möglichkeiten für die Einführung und Betätigung von Abtastwerkzeugen eröffnet.Systems are already known in which the variation or system profile is assigned to the key chest area, that is to say the area which carries the classification notches, while the section adjacent to the key back is equipped with the invariant basic or guide profile. The disadvantage of these assignments of variation and in an invariant basic profile can be seen in the fact that the key channel must be kept in a straight line in the area of the tumblers while maintaining a minimum width, which opens up possibilities for the introduction and actuation of scanning tools.
Zur Vermeidung dieses Nachteils wird von der Erfindung in Umkehrung vom Bekannten vorgeschlagen, das invariante Grundprofil dem Bereich der die Einordnungskerben tragenden Schlüsselbrust zuzuordnen und dieses mit mindestens zwei die Schlüsselmittellinie überschreitenden Profilausbildungen (parazentrische Profilausbildung) zu versehen und das Variations- oder Anlagenprofil in den dem Schlüsselrücken angrenzenden Abschnitt zu verlegen Außerdem soll das Variations- oder Anlagenprofil mindestens ein über . die Schlüsselseitenflächen hinausragendes Sperrippenprofil aufweisen und die Profileinschnitte des invarianten Grundprofils und des Variations- oder Anlagenprofils besitzen einen rechteckigen Querschnitt.In order to avoid this disadvantage, the invention inversely proposes that the known assign the invariant basic profile to the area of the key face bearing the classification notches and to provide this with at least two profile designs (paracentric profile design) that cross the key center line and the variation or system profile in the key spine adjoining section In addition, the variation or system profile should have at least one over. the key side surfaces have protruding locking rib profile and the profile incisions of the invariant basic profile and the variation or system profile a rectangular cross section.
Der hiermit erzielte Vorteil ist darin zu erblicken, daß der Schlüsselkanal im Bereich dieses Grundprofilabschnitts immer eine gezackte Ausbildung aufweist, die Abtastwerkzeugen den Zugang weitgehendst verwehrt, was zur Folge hat, daß die Abtastsicherheit erheblich erhöht ist.The advantage achieved in this way can be seen in the fact that the key channel in the area of this basic profile section always has a jagged design which largely prevents access to the scanning tools, with the result that the scanning security is considerably increased.
Die Erfindung wird anhand der Ausführungsbeispiele darstellenden Figuren 2 bis 4 näher erläutert. Fig. 1 zeigt den Stand der Technik, von dem die Erfindung eine Abkehr bildet. Als dieser Stand der Technik stellt sich ein Schlüssel 1 dar, bei dem das Grundprofil 2 dem dem Schlüsselrücken 3 angrenzenden Abschnitt und das Variationsprofil 4 dem der mit Einordnungseinschnitten versehenen Schlüsselbrust 5 angrenzenden Abschnitt zugeordnet ist. In der Figur 1 sind mögliche Profilvariationen angedeutet, und es versteht sich von selbst, daß der Schlüsselkanal im Bereich des Variationsprofils mindestens die bei 6 gestrichelt angedeutete und, in der Grundform, eine geradlinig begrenzte Öffnung aufweisen muß.The invention is explained in more detail with reference to FIGS. 2 to 4, which represent exemplary embodiments. Fig. 1 shows the prior art, from which the invention forms a departure. This state of the art represents a
Die in den Figuren 2 bis 4 dargestellte Erfindung zeichnet sich dadurch aus, daß das invariante Grundprofil 7 in den die Einordnungskerben enthaltenden Schlüsselabschnitt 5 verlegt ist, während das Anlagen- oder variationsprofil 8 dem schlüsselrückennahen Abschnitt, der sich bis zur Schlüsselmittenpartie erstrecken kann, angehört. In Figur 2 ist ein des Variationsprofils weitgehendst entkleideter übergeordneter Schlüssel gezeigt, während Figur 3 bzw. 4 Schlüssel mit angedeuteten Variationsprofilausbildungen erkennen lassen. Beiden Schlüsseln ist indessen gemeinsam, daß sie im unteren Abschnitt, nämlich dem der Schlüsselbrust 5, ein Grundprofil 7 tragen, das wie die Ausführungsbeispiele zeigen, aus einer die Mittellinie 9 an drei Stellen überschreitenden Prazentrik besteht. Der gestrichelt angedeutete Schlüsselkanal 10 in diesem Abschnitt weist einen das Arbeiten mit Auftastwerkzeugen weitgehendst verhindernden gezackten Verlauf auf. Auch die übrigen Profileinschnitte 12 besitzen einen rechteckigen Querschnitt. Schließlich ist es für die Sicherheit gegen das unbefugte Öffner. des Schlosses wichtig, daß der Schlüssel wenigstens ein Sperrippenprofil aufweist, d.h. ein Profil, das über die Schlüsselfachseite hinausragt, so daß ein Nacharbeiten des Schlüssels nur durch Auftragen von Material erfolgen könnte. Bei den Ausführungen in den Figuren 2 bis 4 sind jeweils 4 Sperrippen vorgesehen.The invention shown in FIGS. 2 to 4 is characterized in that the invariant basic profile 7 is moved into the key section 5 containing the classification notches, while the system or
Ein besonderer lorteil der erfindungsgemäßen Lösung sei abschließend noch hervorgehoben. Die im Querschnitt rechteckige Ausbildung der Profileinschnitte bzw. -erhebungen ermöglicht eine virtschaftliche Herstellung der Schlüssel, und bedingt dadurch kann eine Vielzahl von Variationen vorgenommen werden, weil eine sehr geringe Breite der Profileinschnitte z.B. durch Frässcheiben erzeugt werden kann und damit eine sehr große Anzahl dieser auf kleinstem Raum unterbringbar ist.Finally, a special part of the solution according to the invention should be emphasized. The cross-sectionally rectangular design of the profile incisions or elevations enables the keys to be produced economically, and as a result a large number of variations can be made, because a very small width of the profile incisions e.g. can be generated by milling disks and thus a very large number of them can be accommodated in the smallest space.
