Description

Die Erfindung betrifft eine Vorrichtung zum Schärfen von Schneidwerkzeugen, wie Messer, Scheren , mit einem Schleif- oder Stahlstück, mit einem als durchzugreifenden Handgriff ausgebildeten und mit einer Aufstell- bzw. Auflagefläche an der Unterseite versehenen, bügelförmigen Körper, der an der Vorderseite zur Aufnahme des Schleif- oder Stahlstückes einen nach vorne abstehenden Ansatz aufweist.The invention relates to a device for sharpening Cutting tools, such as knives, scissors, with one Grinding or steel piece, with a handle that can be reached through trained and with a footprint on the underside, bow-shaped body, on the Front to accommodate the grinding or steel piece has a protruding approach.

Eine derartige Vorrichtung ist aus der US-A-5,404,679 bekannt.Such a device is known from US-A-5,404,679.

Bei der bekannten Vorrichtung handelt es sich um eine tragbare Schärfvorrichtung für Messer od. dgl., die eine Grundplatte besitzt, die auf einer Oberfläche aufgesetzt werden kann und die mit einem Handgriff verbunden ist. Von dem Handgriff aus steht ein Ansatz nach vorne hervor, an dem verschiedene Schärfabschnitte mit keilförmigen Anlageflächen vorgesehen sind, zwischen denen ein Schärfabschnitt angeordnet ist. Ein zu schärfender Gegenstand, wie etwa ein Messer oder eine Schere kann zwischen der keilförmigen Anlagefläche und dem Schärfabschnitt durchgezogen werden und so geschärft werden. The known device is a portable one Sharpening device for knives or the like, which has a base plate, which can be placed on a surface and which is connected with a handle. From the handle stands a forward approach, on which different sharpening sections are provided with wedge-shaped contact surfaces between which a sharpening section is arranged. A to be sharpened Object, such as a knife or scissors between the wedge-shaped contact surface and the sharpening section be pulled through and sharpened.

Mit einer derartigen Vorrichtung ist lediglich ein Schärfen von Messern oder Scheren möglich, während eine Abziehmöglichkeit mittels einer Keramik nicht vorgesehen ist.With such a device is only a sharpening of Knives or scissors possible while a peel option is not provided by means of a ceramic.

Aus der US-A-5,477,753 ist ferner eine Klingenschärfvorrichtung mit einem auf einer Unterlage aufstellbaren Grundkörper bekannt, aus dem nach Aufklappen eines Deckels zwei Keramikstäbe entnommen und in einer winkligen Position zueinander in Öffnungen an dem Grundkörper eingesteckt und so fixiert werden können. Die beiden Keramikstäbe können so zum Schärfen oder Abziehen etwa von Messern od. dgl. verwendet werden.From US-A-5,477,753 is also a blade sharpening device known with a base body that can be set up on a base, after opening a lid two ceramic rods removed and in an angular position to each other in openings can be plugged into the base body and thus fixed. The two ceramic rods can be sharpened or removed such as knives or the like.

Gegenüber diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zum Schärfen von Schneidwerkzeugen zu schaffen, die einerseits ein Schärfen und andererseits ein Abziehen von Schneidwerkzeugen ermöglicht und darüber hinaus eine möglichst breite Anwendungsmöglichkeit aufweist.The object of the invention lies in relation to this prior art based, a device for sharpening cutting tools to create sharpening on the one hand and on the other hand allows cutting tools to be pulled off and above also has the broadest possible application.

Diese Aufgabe wird bei einer Vorrichtung gemäß der eingangs genannten Art dadurch gelöst, daß unter dem Ansatz ein nach vorne längsverschiebbarer Keramikstab angeordnet ist.This object is achieved in a device according to the above Kind of solved in that under the approach a forward longitudinally displaceable ceramic rod is arranged.

Durch den unter dem Ansatz vorgesehenen, längsverschiebbaren Keramikstab wird hierbei die Möglichkeit eröffnet, einen Ausgleich der mit dem Schleif- oder Stahlstück geschärften Schneide des Schneidwerkzeuges vorzunehmen. By the longitudinally displaceable provided under the approach Ceramic rod opens up the possibility of compensation the edge sharpened with the grinding or steel piece of the cutting tool.

Gemäß einer besonderen Ausbildung kann der Ansatz zur Aufnahme des Schleif- oder Stahlstückes schräg nach oben im Winkel von ca. 10° ausgebildet sein. Auf diese Weise ist eine besonders leichte Handhabung der Vorrichtung gemäß der Erfindung möglich.According to a special training, the approach to include the Grinding or steel piece formed obliquely upwards at an angle of approximately 10 ° his. This makes the Device according to the invention possible.

Der Keramikstab kann an einem Kunststoffteil befestigt sein, das in einer Aussparung im Unterteil des bügelförmigen Körpers verschiebbar angeordnet ist.The ceramic rod can be attached to a plastic part that in a Recess in the lower part of the bow-shaped body slidably arranged is.

Schließlich kann der Ansatz zur Aufnahme des Schleif- oder Stahlstückes im unteren Bereich eine Aussparung aufweisen, die durch eine auf den bügelförmigen Körper aufschiebbare Kappe abgedeckt werden kann. Die Kappe kann die gleiche Fläche wie der bügelförmige Körper an der Unterseite aufweisen. Damit wird nicht nur der Keramikstab geschützt, sondern die Auflage des bügelförmigen Körpers wird damit verbessert.Finally, the approach to receiving the grinding or steel piece have a recess in the lower area, which by a on the bow-shaped body slidable cap can be covered. The Cap can be the same area as the bow-shaped body at the bottom exhibit. This not only protects the ceramic rod, but also the support of the bow-shaped body is improved.

Anhand der Zeichnungen soll am Beispiel einer bevorzugten Ausführungsform die Vorrichtung gemäß der Erfindung näher erläutert werden.The drawings are based on the example of a preferred embodiment the device according to the invention will be explained in more detail.

    • Wie sich aus den Figuren der Zeichnungen ergibt, besteht die Vorrichtung gemäß der Erfindung aus einem als Handgriff ausgebildeten, bügelförmigen Körper 1, der zum Festhalten eine Durchgreiföffnung 2 aufweist. Der Körper 1 weist an seiner Unterseite eine Aufstell- bzw. Auflagefläche 3 auf, wodurch der Körper fest auf eine stabile Unterlage, beispielsweise auf einen Tisch, aufgestellt werden kann.As can be seen from the figures of the drawings, the device consists according to the invention from a bow-shaped as a handle Body 1, which has a reach-through opening 2 for holding. The Body 1 has a mounting surface 3 on its underside on, whereby the body firmly on a stable surface, for example a table that can be set up.

    An der Vorderseite weist der bügelförmige Körper 1 einen nach vorne stehenden Ansatz 4 auf, in den ein Kunststoffteil 5 eingesetzt ist, in dem sich das Schleif- oder Stahlstück 6 befindet. Der Ansatz 4 verläuft schräg nach oben, so daß die Fläche des Schleif- oder Stahlstückes 6 mit der Grundfläche 3 einen Winkel von ca. 10° bildet.At the front, the bow-shaped body 1 has a protruding front Approach 4, in which a plastic part 5 is inserted, in which the grinding or steel piece 6 is located. The approach 4 runs obliquely above, so that the surface of the grinding or steel piece 6 with the base 3 forms an angle of approximately 10 °.

    An der Unterseite weist der Ansatz 4 eine Aussparung 7 auf, in der ein Keramikstab 8 mit kreisrundem Querschnitt längsverschieblich angeordnet ist. Dieser Keramikstab dient zum Ausgleichen von Wellen in dem geschliffenen Schneidwerkzeug. Der Keramikstab 8 ist zu diesem Zweck mit einem Kunststoffteil 9 verbunden, das gleitend im Unterteil des bügelförmigen Körpers angeordnet ist. Zur Längsverschieblichkeit ist das Kunststoffteil 9 mit einem Ansatz 10 versehen, der in einem Schlitz 11 im bügelförmigen Körper 1 herausragt und mit den Fingern verschoben werden kann.On the underside, the neck 4 has a recess 7 in which a Ceramic rod 8 with a circular cross section arranged longitudinally is. This ceramic rod is used to compensate for waves in the ground Cutting tool. The ceramic rod 8 is used for this purpose a plastic part 9 connected, which slides in the lower part of the bow-shaped Body is arranged.
