Description

Die Erfindung betrifft ein Gerät zum Anspitzen von Griffeln. :@Tit dem bisher üblichen, mit Reibfläche versebenen Anspitzer ist keine genau zentrische Spitze zu erzielen. Ferner ist er nicht sauber zu handhaben, da der Griffelstaub die Finger beschmutzt. Diese Nachteile werden beim Griffelspitzer gemäß der Erfindung dadurch vermieden, daß der Spitzer die Form einer konischen Schraubenspirale erhält, deren Windungen auf 'der Innenseite mit Zähnen versehen sind, die beim Eindrehen des Griffels das Material abheben. Die Spirale ist in eine würfelförmige Hülse eingekapselt, die als Handhabe und Auffangbehälter für den Griffelstau'b dient.The invention relates to a device for sharpening pens. : @Tit the previously common sharpener with a rubbing surface is not an exactly centric one To achieve top. Furthermore, it cannot be handled cleanly because the stylus dust dirty fingers. These disadvantages become with the pencil sharpener according to the invention avoided by giving the sharpener the shape of a conical helix, the turns of which are provided with teeth on the inside, which when screwed in lift off the material with the stylus. The spiral is encapsulated in a cube-shaped sleeve, which serves as a handle and collecting container for the stylus stick.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt, und zwar zeigt Abb. i eine Vorderansicht, Abb. 2 eine Seitenansicht und Abb. 3 einen Schnitt nach der Linie A-B der Abb. 2.An embodiment is shown in the drawing, namely Fig. 1 shows a front view, Fig. 2 shows a side view and Fig. 3 shows a section according to the line A-B of Fig. 2.

Der Griffelspitzer besteht aus der konischen Spirale b, die vom Behälter c umschlossen ist und eine Einstecköffnung a für den Griffel aufweist. Die Innenseite der die Spirale bildenden Windungen ist mit Zähnen versehen. Durch Drehen des eingeschobenen Griffels wird durch den wirksamen Teil des spiraligen Anspitzaggregates b das Material vom Griffel abgeschabt. Der anfallende Schleifstaub fängt sich in der Hülse c, die die Schraubenspirale umgibt und zur besseren Handhabung und zum Auffangen des Staubes dient.The pencil sharpener consists of the conical spiral b that comes from the container c is enclosed and has an insertion opening a for the stylus. The inside the turns forming the spiral are provided with teeth. By turning the inserted The stylus becomes the material through the active part of the spiral sharpening unit b scraped off the stylus. The resulting grinding dust is caught in the sleeve c, the the spiral surrounds and for better handling and for collecting the dust serves.

Der erfindungsgemäße Griffelspitzer hat gegenüber den bisher üblichen Spitzern den Vorteil, daß die Anspitzzeit verhältnismäßig kurz ist und daß ferner eine genau zentrische, .glatte und saubere Spitze erzielt wird. Der anfallende Schleifstaub dringt nicht mach außen, sondern wird in der Hülse festgehalten.The pencil sharpener according to the invention has compared to the hitherto customary Sharpening has the advantage that the sharpening time is relatively short and that furthermore a precisely centric, smooth and clean tip is achieved. The resulting grinding dust does not penetrate outside, but is held in the sleeve.
