Description

Gegenstand der Erfindung ist ein Spitzer für Füllstifte mit Einstellvorrichtung für die Spitzenstärke und federnd angeordneter Führungsbüchse für den Füllstift.The invention relates to a sharpener for fountain pens with an adjusting device for the tip thickness and a spring-mounted guide bush for the filler pen.

Der Spitzer besteht aus: dem schrägverzahnten Fräser i in Form eines Kegelstumpfes, welcher durch Lagerzapfen 2 an einem topfförmigen Gehäuse 3 befestigt ist, und dem drehbaren Einsatz, bestehend aus der mittels Deckelblech q. oder einer U-förmig gebogenen Blattfeder 5 mit Lagerbüchse 6 federnd verbundenen Führungsbüchse 7 für, den Füllstift. DerAnschlag 8 begrenzt den durch Drehen der Einstellschraube 9 einstellbaren, axialen Vorschub des Füllstifts, wodurch sich entsprechend der kegelförmigen Verjüngung des Fräsers eine Zu- oller Abnahme der Spitzenstärke ergibt.The sharpener consists of: the helical cutter i in the form of a Truncated cone, which is attached to a cup-shaped housing 3 by bearing pins 2 is, and the rotatable insert, consisting of the cover plate q. or one U-shaped bent leaf spring 5 with bearing bush 6 resiliently connected guide bush 7 for, the filler pen. The stop 8 limits that by turning the adjusting screw 9 adjustable, axial feed of the filler pin, which results in accordance with the conical tapering of the milling cutter results in an additional decrease in the tip thickness.

Beim Einsetzen des Füllstifts bis zum Anschlag 8 hebt sich das in Richtung zur Fräserachse unter Federdruck stehende untere Ende der Führungsbüchse 7 entsprechend der nachzuspitzenden Schichtdicke vom Anschlag io ab und verhindert hierdurch ein Überschreiten des zulässigen radialen Anpreßdruckes, der ein Abbrechen der Minenspitzß zur Folge hätte. Das Spitzen erfolgt durch eine kreisende Bewegung mit festgehaltenem Füllstift. Zum Entleeren wird der mit dem Deckel verbundene drehbare Einsatz abgenommen. Zur Schonung des Füllstifts kann am oberen Rand der Führungsbüchse 7 eine kugelgelagerte Büchse angeordnet werden.When inserting the filler pen up to the stop 8, the in In the direction of the milling cutter axis, the lower end of the guide bushing is under spring pressure 7 depending on the layer thickness to be sharpened from the stop io and prevents as a result, the permissible radial contact pressure is exceeded, causing a break the mine spike would result. Sharpening takes place in a circular motion with the pen held down. The rotatable one connected to the lid is used for emptying Insert removed. To protect the filler pen you can at the top of the guide bush 7 a ball bearing bush can be arranged.
