Description

Griffelanspitxer mit radialen Schärfkanten aus keramischem IKaterial. Gegenstand der Erfindung ist ein Griffelanspitzer mit radialen, Schärfkanten aus kera-mischem Material (z. B. Porzellan). In den keramischen Spitzerkörper sind konisch verlaufende und mit nach innen gerichteten Zakken versehene Öffnungen eingepreßt. Jeder Zacken hat eine radial verlaufende Schärfkante. Die äußeren Flächen des prismatisch geformten Spitzerkörpers sind gerauht oder geriffelt.Stylus sharpener with radial sharpening edges made of ceramic I material. The invention relates to a handle with radial Elan Spitzer, sharpening edges of ceramic mis chem material (eg. As porcelain). In the ceramic sharpener body, conical openings provided with inwardly directed teeth are pressed. Each point has a sharpening edge running radially. The outer surfaces of the prismatically shaped sharpener body are roughened or fluted.

Der Vorteil dieses Griffelanspitzers gegenüber den bisher bekannten Ausführungen liegt in der einfachen und billigen Herstellung, da derselbe aus nur einem einzigen Teil bestehe, der in einem Arbeitsgang in die entsprechende Form ;gebracht wird. Außerdem besitzt das Material desselben eine große Härte, durch welche eine gute Schnitt-und Schleiffähigkeit erzielt wird.The advantage of this pencil sharpener over the previously known Execution lies in the simple and cheap production, since the same from only a single part that is shaped in one operation ; is brought. In addition, the material of the same has a great hardness, through which can be cut and grinded well.

Die Abbildungen. stellen eine beispielsweise Ausführungsform des Griffelanspitzers dar, und zwar zeigt Abb. i einen Schnitt durch eine der konischen Öffnungen, Abb.2 eine Seitenansicht auf eine der Außenflächen des Spitzerkörpers und Abb. 3 eine Draufsicht auf die konischen Öffnungen.The illustrations. represent an example embodiment of the pencil sharpener Fig. i shows a section through one of the conical openings, Fig.2 a side view of one of the outer surfaces of the sharpener body and Fig. 3 a Top view of the conical openings.

Die konischen Öffnungen bzw. Löcher i, die einzeln oder auch zu mehreren im Spitzerkörper vorgesehen sein können, sind mit nach innen gerichteten Zacken a versehen. Die Schärfkanten der Zacken a verlaufen in. radialer Richtung, so daß durch diese Ausgestaltung und Stellung der Zacken a jede öff-. nung i als konischer Hohlfräse, ausgebildet ist. In diese Öffnungen i wird: das zu spitzende Griffelende gesteckt und so lange herumgedreht, bis eine konische, am vorderen Ende jedoch noch abgeflachte Form entsteht, wie sie in -der Abb. q. dargestellt ist. Zur Herstellung der noch, fehlenden Spitze wird das Griffelende sodann auf den gerauhten oder geriffelten Flächen 2 oder 3 des Spitzerkörpers hin und: her gescheuert, wodurch die Spitze (Abb. 5) auf bekannte Weise entsteht.The conical openings or holes i, individually or in groups May be provided in the sharpener body are with inwardly directed prongs a provided. The sharpening edges of the prongs a run in the radial direction, so that by this configuration and position of the prongs a each open. tion i as conical Hollow milling machine is formed. In these openings i becomes: the end of the pen to be sharpened inserted and turned around until a conical, but still at the front end flattened shape is created, as shown in Fig. q. is shown. For the production The end of the stylus is then applied to the roughened or fluted end of the point that is still missing Areas 2 or 3 of the sharpener body rubbed back and forth, causing the tip (Fig. 5) arises in a known way.
