Herkömmliche Schlüssel dieser Art sind als Flachschlüssel ausgebildet, bei denen an den Seitenflächen des Flachschlüssels jeweils ein Steuernutensatz angeordnet ist. Ein solcher Flachschlüssel ist beispielsweise aus der AT-PS 389 559 bekannt.Conventional keys of this type are designed as flat keys, in which on the side surfaces of the flat key a control groove set is arranged. Such a flat key is known for example from AT-PS 389 559.

Mit der vorliegenden Erfindung soll ein Schlüssel für Zylinderschlösser vorgesehen werden, bei dem unter Beibehaltung einer sehr hohen Anzahl an Variationsmöglichkeiten eine erhöhte Sperrsicherheit sowie eine erhöhte Nachschlüssel-Sicherheit gegeben ist. Dies wird erfindungsgemäß dadurch erreicht, dass ein im wesentlichen zylindrischer Schlüsselschaft vorgesehen ist, in dessen räumlich gekrümmte Außenfläche die hauptsächlich in Schlüsseleinschubrichtung verlaufenden und einander zumindest teilweise überschneidenden Steuernuten zumindest eines Steuernutensatzes eingelassen sind.The present invention is intended to provide a key for cylinder locks at increased locking security while maintaining a very high number of possible variations as well as increased duplicate key security. This is according to the invention achieved that a substantially cylindrical key shaft is provided in the spatially curved outer surface which runs mainly in the direction of key insertion and at least partially overlapping tax grooves of at least one tax groove set are.

Bei der erfindungsgemäßen Ausbildung des Schlüssels schließt die räumlich unterschiedliche Konfiguration der über den Umfang des Schlüsselschaftes verteil angeordneten und unter verschiedenen Winkeln in den Schlüsselschaft eingestochenen Steuernuten des jeweiligen Steuernutensatzes eine Anfertigung von Nachschlüsseln praktisch aus. Die Steuernuten jedes Steuernutensatzes erstrecken sich entlang von 3-dimensionalen Raumkurven, die zwar hauptsächlich in Schlüsseleinschubrichtung verlaufen, aber räumlich ineinander verschränkt sind und einander teilweise überschneiden. Selbst wenn die entlang diesen 3-dimensionalen Raumkurven verlaufenden Steuernuten jeweils für sich als radiale Nut mit parallelen Seitenwänden ausgebildet sind, bilden die drei Steuernuten eines Steuernutensatzes, aufgrund der unterschiedlichen Winkellage ihrer Seitenwände, sich entlang dem Schlüsselschaft fortlaufend verändernde Hinterscheidungen. Diese räumlich 3-dimensional hoch komplexe Konfiguration der Steuernuten jedes einzelnen Steuernutensatzes kann zwar mit sehr aufwendigen CNC-Maschinen präzise hergestellt werden. Sie kann aber vom Originalschlüssel nicht mehr mit einer für eine Anfertigung von Nachschlüsseln ausreichenden Genauigkeit abgenommen werden.In the inventive design of the key, the spatially different closes Configuration of the distribution of the key shaft, which is distributed over the circumference of the key shaft, and different Angles in the key shank of the tax grooves of the respective tax groove set a production of duplicate keys practically. The tax grooves of each tax groove set extend along 3-dimensional space curves, which are mainly in the direction of key insertion run, but are spatially intertwined and partially overlap each other. Even if the control grooves running along these 3-dimensional space curves each for are formed as a radial groove with parallel side walls, the three control grooves form one Tax groove set, due to the different angular position of their side walls, along the Key shank continually changing undercuts. This spatially 3-dimensional high complex configuration of the control grooves of each individual control groove set can be very complex CNC machines can be manufactured precisely. But it cannot from the original key more accepted with sufficient accuracy for the production of duplicate keys become.

Um den Komplexitätsgrad der räumlichen Konfiguration der Steuernuten noch weiter zu erhöhen, können die entlang der räumlich gekrümmten Außenfläche des Schlüsselschaftes hauptsächlich in Schlüsseleinschubrichtung verlaufenden Steuernuten mit über ihre Länge unregelmäßig verteilten und unterschiedlich ausgebildeten Hinterschneidungen in die Außenfläche des Schlüsselschaftes eingelassen sein. To further increase the complexity of the spatial configuration of the control grooves, can mainly in the along the spatially curved outer surface of the key shaft Key slots running control grooves with irregularly distributed over their length and differently designed undercuts in the outer surface of the key shaft his.

Um unterschiedliche Variationen in den Hinterscheidungen der Steuernuten eines Steuernutensatz zu erzeugen, können einzelne Steuernuten als Ganzes, oder auch nur stellenweise, statt radial etwas schräg zum jeweiligen Radius mit zueinander parallelen Seitenwänden in den Schlüsselschaft eingestochen werden.To different variations in the undercuts of the tax grooves of a tax groove set can generate individual control grooves as a whole, or only in places, instead of something radial pierced into the key shaft at an angle to the respective radius with parallel side walls become.

Der erfindungsgemäße Schlüssel kann einen hohlen Schlüsselschaft besitzen, der zwei an ihren in Schlüsseleinschubrichtung verlaufenden Seitenrändern miteinander verbundene Halbschalen aufweist, bei denen jeweils ein Satz von Steuernuten in ihre räumlich gekrümmte Außenseite eingelassen ist. Diese ermöglicht eine sehr stabile und gleichzeitig sehr leichte Ausbildung des erfindungsgemäßen Schlüssels.The key according to the invention can have a hollow key shaft, the two on their in Has side shells connected to one another, each of which has a set of control grooves embedded in its spatially curved outside is. This enables a very stable and at the same time very light design of the invention Key.

Gemäß einem weiteren Merkmal der Erfindung kann der Schlüsselschaft rohrförmig ausgebildet sein und an seiner zylindrischen Außenseite zwei einander gegenüberliegende, entlang den Verbindungslinien der beiden Halbschalen in Schlüsseleinschubrichtung verlaufende Längsrippen oder Längsnuten besitzen. Diese Ausbildung erlaubt den Einsatz des Schlüssels als Wendeschlüssel.According to a further feature of the invention, the key shaft can be tubular be and on its cylindrical outside two opposite one another, along the connecting lines of the two half shells extending in the direction of the key insertion or Have longitudinal grooves. This training allows the use of the key as a reversible key.
