Anspitzer für Schreib-, Zeichen- und KosmetikstifteSharpeners for writing, drawing and cosmetic pencils
Die Erfindung bezieht sich auf einen Anspitzer für Schreib-, Zeichen- und Kosmetikstifte, mit einem Spitzkörper, der innere konische Führungsflächen für das anzuspitzende Stiftende . aufweist, und mit einem spanabhebenden Schneidwerkzeug oder Messer, das im wesentlichen parallel zu einer Mantellinie des Führungskonus in diesen unter einem Schneidwinkel um ein " kleines Stück hineinragt, gemäß Oberbeghriff des Anspruchs 1.The invention relates to a sharpener for writing, drawing and cosmetic pencils, with a sharpening body which has inner conical guide surfaces for the pencil end to be sharpened, and with a cutting tool or knife which projects into the guide cone by a small amount at a cutting angle, essentially parallel to a surface line of the guide cone, according to the preamble of claim 1.
Solche Anspitzer sind seit langem in den verschiedensten Ausführungen bekannt. Insbesondere sind solche bekannt, bei denen das Schneidwerkzeug oder das Messer am Spitzkörper in einer passenden Ausnehmung verdrehsicher festgeschraubt sind. Bei einigen Ausführungen ist eine Ersatzschneide in einer weiteren, seitlichen Ausnehmung festgeschraubt. Es sind daher eine Mehrzahl von Einzelteilen und Bearbeitungsvorgängen für den fertigen Anspitzer erforderlich. Durch das DE-GM 70 27 546 ist ferner ein Schärfer für Schreib- und Zeichenminen bekannt, bei dem das Schneidwerkzeug aus AI2O3 oder gesintertem AI2O3 besteht. Abgesehen davon, daß dieser bekannte Minenschärfer nicht gattungsgemäß ist, besteht auch er aus einer Mehrzahl von Eintelteilen.Such sharpeners have been known for a long time in a wide variety of designs. In particular, those are known in which the cutting tool or the knife is screwed securely into a suitable recess on the sharpener body. In some designs, a replacement blade is screwed into another, lateral recess. A number of individual parts and processing steps are therefore required for the finished sharpener. DE-GM 70 27 546 also discloses a sharpener for writing and drawing leads in which the cutting tool is made of AI2O3 or sintered AI2O3. Apart from the fact that this known lead sharpener is not of the generic type, it also consists of a number of individual parts.
Der Erfindung liegt die Aufgabe zugrunde, einen Bleistift- und Buntstiftanspitzer der eingangs genannten Art zu schaffen, bei dem zur Herstellung weniger Einzelteile und Arbeitsschritte benötigt werden. Außerdem soll die Schärfe der Schneide mindestens ebenso gut, wenn nicht besser, sein als bei den bisherigen gattungsgemäßen Anspitzern.The invention is based on the object of creating a pencil and colored pencil sharpener of the type mentioned at the beginning, which requires fewer individual parts and work steps to manufacture. In addition, the sharpness of the blade should be at least as good, if not better, than with previous sharpeners of this type.
Erfindungsgemäß wird die gestellte Aufgabe bei einem Anspitzer gemäß Oberbegriff des Anspruchs 1 durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst, nämlich dadurch, daß der Spitzkörper mit der Schneidwerkzeug oder Messer einstückig ist und aus einer zur Bildung einer scharfen Schneide geeigneten Sinterkeramik besteht. Vorteilhafte Weiterbildungen sind in den Ansprüchen 2 bis 6 angegeben.-Der Anspitzer kann mit Vorteil aus einer Oxidkeramik in Form von Aluminium-Oxid (AI2O3) hergestellt sein. In der Natur vorkommendes (X-AI2O3 wird als Korund bezeichnet. Eine andere geeignete Oxidkeramik zur Herstellung des Anspitzers ist Zirconium-Oxid (&Zgr;&Ggr;&Ogr;2). Es hat sich gezeigt, daß auch andere Sinterkeramiken als Materialien für den Bleistift- und Buntstiftanspitzer geeignet sind, so Siliciumcarbid (SiC) oder Siliciumnitrid (S13N4).According to the invention, the stated object is achieved in a sharpener according to the preamble of claim 1 by the features specified in the characterizing part of claim 1, namely in that the sharpening body is one piece with the cutting tool or knife and consists of a sintered ceramic suitable for forming a sharp cutting edge. Advantageous further developments are specified in claims 2 to 6. The sharpener can advantageously be made from an oxide ceramic in the form of aluminum oxide (AI2O3). Naturally occurring (X-AI2O3) is called corundum. Another suitable oxide ceramic for producing the sharpener is zirconium oxide (ZrO2). It has been shown that other sintered ceramics are also suitable as materials for the pencil and colored pencil sharpener, such as silicon carbide (SiC) or silicon nitride (Si3N4).
Zweckmäßigerweise ist der Spitzkörper an seinem integralen Schneidwerkzeig oder Messer schärfbar bzw. nachschärfbar ausgeführt.The pointed body is conveniently designed to be sharpenable or resharpenable on its integral cutting tool or knife.

Erfindung noch näher erläutert. In der Zeichnung zeigt:Invention explained in more detail. The drawing shows:

auf die vordere Stirnseite und die andere Seitenflanke.on the front face and the other side flank.
Der Anspitzer AS für Schreib-, Zeichen- und Kosmetikstifte nach Fig. 1 bis 3 besteht aus einem Spitzkörper 1, der innere konische Führungsflächen 2 für das anzuspitzende Stiftende aufweist, und aus einem spanabhebenden Schneidwerkzeug oder Messer 3, das im wesentlichen parallel zu einer Mantellinie des Führungskonus (Achse 2.0) in diesen unter einem Schneidwinkel um ein kleines Stück hineinragt (siehe insbesondere Fig. 2). Erfindungsgemäß ist der Spitzkörper 1 mit der Schneidwerkzeug oder Messer 3 einstückig und besteht aus einer zur Bildung einer scharfen Schneide geeigneten Sinterkeramik.The sharpener AS for writing, drawing and cosmetic pencils according to Fig. 1 to 3 consists of a sharpening body 1, which has inner conical guide surfaces 2 for the pencil end to be sharpened, and of a cutting tool or blade 3, which extends essentially parallel to a surface line of the guide cone (axis 2.0) into the latter at a cutting angle by a small distance (see in particular Fig. 2). According to the invention, the sharpening body 1 is in one piece with the cutting tool or blade 3 and consists of a sintered ceramic suitable for forming a sharp cutting edge.
Der Spitzkörper 1 ist an seinem integralen Schneidwerkzeug 3 schärfbar bzw. nachschärfbar ausgebildet. Das Schärfen erfolgt insbesondere durch Schleifen mittels Schleifscheibe, deren Schleifkörnung naturgemäß härter sein muß als der Werkstoff des Anspitzers. Da die Sinterkeramik sich durch eine große Härte auszeichnet, wird zum Schärfen eine Schleifscheibe mit noch härterer Sinterkeramik oder eine Diamant-Scheifscheibe verwendet.The sharpening body 1 is designed to be sharpenable or resharpenable on its integral cutting tool 3. Sharpening is carried out in particular by grinding using a grinding wheel, the abrasive grain of which must naturally be harder than the material of the sharpener. Since the sintered ceramic is characterized by great hardness, a grinding wheel with an even harder sintered ceramic or a diamond grinding wheel is used for sharpening.
Wie bereits eingangs erwähnt, sind geeignete Sinterkeramiken für den Anspitzer: Aluminium-Oxid (AI2O3X Zirconium-Oxid (ZrC^), Siliciumcarbid (SiC) oder Siliciumnitrid (S13N4), wobei diese Aufzählung weitere (nicht genannte) Sinterkeramiken nicht ausschließt.As already mentioned at the beginning, suitable sintered ceramics for the sharpener are: aluminum oxide (AI2O3X), zirconium oxide (ZrC^), silicon carbide (SiC) or silicon nitride (S13N4), whereby this list does not exclude other (not mentioned) sintered ceramics.
