Description

Wechsel-Schreib- und Zeichenstift o.@dgl. Die Erfindung betrifft einen Wechsel-Schreib- und Zeichenstift o. dgl., -deren :._ Hülsen in an sich bekannter Weise in einem Ring des zentrischen Trägers hängen und von der zugespitzten Deckhülse eingeschlossen sind. Der Aufhängering ist dabei als Sprengring ausgebildet, welcher durch seine Federung im Träger festgehalten wird. Es hat sich erwiesen, daß diese Befestigungsart nicht genügt, weil der Aufhängering ohne Anstrengung glatt aus dem Träger herausgezogen werden kann, was beispielsweise beim Wechseln der Minenhülsen oftmals vorkommt.Exchange pen and drawing pen or similar The invention relates to a Interchangeable writing and drawing pen or the like, -whose: ._ Sleeves in per se known Way hang in a ring of the central support and from the tapered cover sleeve are included. The suspension ring is designed as a snap ring, which is held by its suspension in the carrier. It has been shown that this The type of fastening is not sufficient because the suspension ring can be pulled out smoothly without effort Carrier can be pulled out, for example when changing the lead case often occurs.

Die Erfindung beseitigt diesen Nachteil. Sie kennzeichnet sich dadurch, daß der Aufhängering durch umgebogene Zacken einerauf dem Träger aufgesetzten Krone gehalten wird.The invention overcomes this disadvantage. It is characterized by that the suspension ring by bent prongs of a crown placed on the carrier is held.

In der Zeichnung ist ein Wechsel-Schreib-und Zeichenstift o. dgl. nach der Erfindung in einer beispielsweisen Ausführungsform dargestellt.In the drawing, an interchangeable writing and drawing pen or the like is shown. shown according to the invention in an exemplary embodiment.

Abb. i zeigt den Stift schaubildlich beim Einführen bzw. Wechseln einer Minenhülse. Die Abb. 2 und 3 zeigen Einzelheiten in größerem Maßstabe.Fig. I shows the pin as it is being inserted or changed a lead case. Figures 2 and 3 show details on a larger scale.

Hierbei ist a der Kolben, an welchem der stabförmige Minenhülsenträger b zentrisch befestigt ist, der oben die Krone c trägt, an welcher die Minenhülsen d mittels ihrer Gewindespindeln e schwenkbar befestigt sind. Die zugespitzte Deckhülse f ist abnehmbar; ä ist eine Schraubhülse für Ersatzminen.Here, a is the piston on which the rod-shaped lead case carrier b is fastened centrally, which carries the crown c above, on which the lead sleeves d are pivotally mounted by means of their threaded spindles e. The pointed cover sleeve f is removable; ä is a screw sleeve for replacement leads.

Die Krone e (Abb.2) besteht aus einem birnenförmigen Körper, dessen hinterer Teil 1a am Ende des Minenhülsenträgers befestigt (z. B. mit diesem verschraubt) ist und dessen vorderer Teil Zacken i bildet, die durch Radialeinschnitte hergestellt werden. Der von den Zacken i eingeschlossene Raum nimmt einen Aufhängering h auf, an welchem die Gewindespindeln e der Minenhülsen lose hängen. Die Befestigung des Aufhängeringes erfolgt, wie aus Abb.2 rechts ersichtlich, durch Umbiegen der Zackenspitzen, wodurch jede schädliche Beanspruchung der Zacken an ihrer Wurzel vermieden und eine sichere Befestigung des Aufhängeringes h erreicht wird. Dieser ist damit in der Krone gefaßt und kann nicht mehr samt den Minenhülsen aus ihr herausgerissen werden.The crown e (Fig.2) consists of a pear-shaped body, whose rear part 1a attached to the end of the lead case carrier (e.g. screwed to it) and the front part of which forms prongs i, which are produced by radial incisions will. The space enclosed by the prongs i accommodates a suspension ring h, on which the threaded spindles e of the lead sleeves hang loosely. The attachment of the The suspension ring is made, as can be seen on the right in Fig. 2, by bending the tips of the teeth, thereby avoiding any harmful stress on the prongs at their roots and providing a secure attachment of the hanger ring h is achieved. This is thus in the The crown is seized and can no longer be torn out of it together with the mine sleeves.

Die Spitze L jeder Minenhülse d (Abb. 3) ist kegelstumpfförmig verjüngt, so daß sie sich beim Vorschrauben der Minenhülse an die Innenwand der Deckhülsenspitze anlegt und damit hier ein Widerlager findet, welches das zu weite Herausschieben der Minenhülge verhindert. Die Deckhülse klemmt dabei die Minenhülse so fest zusammen, daß man durch Drehen des Kolbens a abgeschriebene Minen aus der Hülse vorschrauben kann.The tip L of each lead case d (Fig. 3) is tapered in the shape of a truncated cone, so that when the lead case is screwed forward, it rests against the inner wall of the cover case tip and thus finds an abutment here, which prevents the lead case from being pushed out too far. The cover sleeve clamps the lead sleeve together so tightly that you can screw the copied leads out of the sleeve by turning the piston a.
