Abstract

The key has a shaft (1) and bow (2). The recesses (5,6) are formed on protruding side of the locking notches (8,9). A web (7) is arranged in center of the shaft. The shaft is provided with offset sectional shafts (3,4) which are connected with each other using web.

Description

Die Erfindung betrifft einen Schlüssel für einen Schließzylinder mit einem Schaft, mit in dem Schaft angeordneten Ausnehmungen, wobei der Schaft in einem zur Längsachse senkrechten Querschnitt stufenförmig gestaltet ist, derart dass der Schaft zwei in ihrer Ebene zueinander versetzte Teilschäfte hat und die Teilschäfte über einen Steg miteinander verbunden sind, so dass Breitseiten des Schaftes in einer Draufsicht jeweils eine hervorstehende Seite und eine zurückgesetzte Seite aufweisen.The invention relates to a key for a lock cylinder with a shaft, arranged in the shaft recesses, wherein the shaft is designed stepwise in a vertical cross-section to the longitudinal axis, such that the shaft has two in their plane staggered partial shafts and the partial shafts via a web connected to each other, so that broad sides of the shaft in a plan view each have a protruding side and a recessed side.

Ein solcher Schlüssel hat durch den Versatz der Teilschäfte und des Stegs eine in Längsrichtung des Schaftes weisenden Kröpfung und ist beispielsweise aus der DE 25 16 340 A bekannt. Der Steg ist in der Mitte des Schaftes angeordnet. Bei diesem Schlüssel sind die Ausnehmungen ausschließlich als in den Schmalseiten angeordnete Schließkerben ausgebildet. Dies führt zu einer sehr geringen Anzahl an unterschiedlich ausgestalteten Schließkerben und damit zu einer geringen Anzahl an Schließvarianten.Such a key has by the offset of the partial shafts and the web a pointing in the longitudinal direction of the shaft crank and is for example from the DE 25 16 340 A known. The bridge is located in the middle of the shaft. In this key, the recesses are designed exclusively as arranged in the narrow sides locking notches. This leads to a very small number of differently designed locking notches and thus to a small number of locking variants.

Weiterhin ist aus der DE 41 23 378 A1 ein Schlüssel bekannt geworden, bei dem mehrere Längsnuten unmittelbar an den Steg angrenzen. In einer Draufsicht auf den Schaft sind die an den Steg angrenzenden Längsnuten auf der zurückgesetzten Seite angeordnet. Dies führt zu einer großen Länge des Steges und damit zu einer geringen Stabilität des Schaftes.Furthermore, from the DE 41 23 378 A1 a key has become known in which several longitudinal grooves directly adjacent to the web. In a plan view of the shaft, the longitudinal grooves adjoining the web are arranged on the recessed side. This leads to a large length of the web and thus to a low stability of the shaft.

Aus der DE 195 48 426 A1 ist ein Schlüssel bekannt geworden, bei dem zwei Teilschäfte durch einen Knick des Schaftes voneinander getrennt sind. In dem Knick sind Längsnuten angeordnet, welche den Querschnitt des Schaftes und damit dessen Stabilität schwächen.From the DE 195 48 426 A1 a key has become known in which two partial shafts are separated by a kink of the shank. In the bend longitudinal grooves are arranged, which weaken the cross section of the shaft and thus its stability.

Der Erfindung liegt das Problem zugrunde, einen Schlüssel der eingangs genannten Art so weiter zu bilden, dass er eine besonders hohe Anzahl an Schließvarianten ermöglicht und eine hohe Stabilität aufweist.The invention is based on the problem to form a key of the type mentioned so on that it allows a particularly high number of locking variants and has a high stability.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass eine dem Steg am nächsten liegende Ausnehmung auf der hervorstehenden Seite der Breitseiten angeordnet ist.This problem is solved according to the invention in that a recess located closest to the web is arranged on the protruding side of the broad sides.

Durch diese Gestaltung lässt sich die Länge des Steges besonders kurz gestalten. Damit wird eine Schwächung des Schaftes durch den Versatz der Teilschäfte vermieden. Durch die erfindungsgemäße Anordnung der Ausnehmungen auf dem Schaft lässt sich eine hohe Anzahl an Schließvarianten erzeugen.With this design, the length of the bridge can be made particularly short. Thus, a weakening of the shaft is avoided by the offset of the partial shafts. The inventive arrangement of the recesses on the shaft can produce a large number of locking variants.

Zur weiteren Erhöhung der Stabilität des erfindungsgemäßen Schlüssels trägt es bei, wenn eine Wandung der dem Steg am nächsten liegenden Ausnehmung in einer Draufsicht auf die Breitseite des Schaftes von dem Steg weg geneigt ist. Diese Gestaltung trägt zu einer Erhöhung der Wandstärke des Steges bei. Vorzugsweise verjüngen sich dabei die Ausnehmungen zu einem Grund hin.To further increase the stability of the key according to the invention, it contributes, if a wall of the web nearest the web is inclined away from the web in a plan view of the broad side of the shaft. This design contributes to an increase in the wall thickness of the web. Preferably, the recesses taper to a bottom.

Eine hohe Anzahl von Schließvarianten des erfindungsgemäßen Schlüssels lässt sich einfach erreichen, wenn zumindest eine der Ausnehmungen als in den Breitseiten angeordnete Längsnut ausgebildet ist. Diese Gestaltung trägt zu einer Erhöhung des Schutzes eines mit dem erfindungsgemäßen Schlüssel zu schließenden Schließzylinders bei, weil derartige, als Längsnut ausgebildete Ausnehmungen von einem Profilsteg im Schließzylinder ausgefüllt werden können. Dieser Profilsteg erschwert das Einführen eines Werkzeuges zum Manipulieren nach der Pickingmethode.A high number of locking variants of the key according to the invention can be achieved easily if at least one of the recesses is formed as arranged in the broad sides of the longitudinal groove. This design contributes to an increase in the protection of a key to be closed with the key according to the invention, because such, designed as a longitudinal groove recesses can be filled by a profile web in the lock cylinder. This profile web makes it difficult to insert a tool for manipulating the picking method.

Der erfindungsgemäße Schlüssel lässt eine Vielzahl von Schließvarianten zu, wenn mehrere Ausnehmungen als in zumindest einer der Schmalseiten angeordnete Schließkerben ausgebildet sind. Ein weiterer Vorteil dieser Gestaltung besteht darin, dass der Schlüssel wegen des Versatzes der Teilschäfte nur schwierig mit üblichen Werkzeugen kopiert werden kann, weil diese den Schlüssel an der den Schließkerben abgewandten Seite des Schaftes einspannen. Damit sind Einspannung und Schließkerben zueinander versetzt, wodurch eine Fehlergefahr beim Kopieren steigt. Der Versatz der Teilschäfte führt auch bei dieser Gestaltung der Ausnehmungen zu einer Erschwerung des unberechtigten Entriegelns des Schließzylinders nach der Pickingmethode, weil der Versatz den Bauraum zum Einführen des Werkzeugs verringert.The key according to the invention permits a multiplicity of closing variants if a plurality of recesses are designed as closing notches arranged in at least one of the narrow sides. Another advantage of this design is that the key because of the offset of the partial shafts difficult to copy with conventional tools, because they clamp the key on the side facing away from the locking notches of the shaft. This clamping and locking notches are offset from each other, whereby a risk of error during copying increases. The offset of the partial shanks leads in this design of the recesses to an aggravation of unauthorized Entriegelns the lock cylinder according to the Pickingmethode, because the offset reduces the space for inserting the tool.

Der bauliche Aufwand zur Erzeugung einer besonders großen Anzahl an Schließvarianten oder alternativ zur Erzeugung des Wendeschlüssels lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders gering halten, wenn mehrere Ausnehmungen als Reihe von Kalotten ausgebildet und auf beiden Breitseiten angeordnet sind.The structural complexity for generating a particularly large number of locking variants or alternatively for generating the reversible key can be kept particularly low according to another advantageous embodiment of the invention, when a plurality of recesses are formed as a series of calottes and arranged on both broad sides.

Ein als Wendeschlüssel gestalteter erfindungsgemäßer Schlüssel ist besonders einfach aufgebaut, wenn die als Reihe von Kalotten ausgebildeten Ausnehmungen ausschließlich auf der jeweils hervorstehenden Seite des Schaftes angeordnet sind. Ein weiterer Vorteil dieser Gestaltung besteht darin, dass die als Kalotten ausgebildeten Ausnehmungen besonders tief sein können, so dass eine besonders große Anzahl an Stufensprüngen und damit eine große Anzahl an Schließvarianten erzeugt werden kann.An inventive key designed as a reversible key is of particularly simple construction if the recesses formed as a series of calottes are arranged exclusively on the respectively protruding side of the shaft. Another advantage of this design is that the recesses formed as dome can be particularly deep, so that a particularly large number of increments and thus a large number of closing variants can be generated.

Zur weiteren Erschwerung der Manipulation des mit dem erfindungsgemäßen Schlüssel zu schließenden Schließzylinders trägt es bei, wenn die als Längsnut ausgebildete Ausnehmung außermittig in der Reihe der als Kalotten ausgebildeten Ausnehmungen angeordnet ist. Die Lage der als Längsnut ausgebildeten Ausnehmung verhindert ein gerades Ansetzen des Manipulationswerkzeuges.To further complicate the manipulation of the key according to the invention to be closed with the lock cylinder, it contributes, if designed as a longitudinal groove recess is arranged eccentrically in the row of recesses formed as dome. The position of the recess formed as a longitudinal groove prevents a straight attachment of the manipulation tool.

Der erfindungsgemäße Schlüssel lässt sich besonders komfortabel handhaben, wenn sich an den Versatz der Teilschäfte eine ebene Reide anschließt.The key according to the invention can be handled in a particularly comfortable manner if a flat recess adjoins the offset of the partial shafts.

Der erfindungsgemäße Schlüssel lässt sich besonders kostengünstig fertigen, wenn sich der Versatz der Teilschäfte über eine sich an den Schaft anschließende Reide erstreckt.The key according to the invention can be produced in a particularly cost-effective manner if the offset of the partial shanks extends beyond a tail adjoining the shaft.
