Description

Schreibstift mit verschiebbarer raine. Gemäß der Erfindung erfolgt das Festhalten >der Bleimine in Schreibstiften durch Verwinden einer Schraubenfeder, die mit ihrem einen. Ende an. einer drehbar in der Bleistifthülse liegenden Minenhülse und mit ihrem anderen Ende an der äußeren Hülse befestigt ist.Writing pen with sliding raine. Takes place according to the invention holding> the lead in pens by twisting a coil spring, the one with her one. End at. a lead case rotatable in the pencil case and is attached at its other end to the outer sleeve.

In der Zeichnung ist ein solcher Schreibstift durch Abb. r in einer Ansicht und durch A#bb. 2 in einem Längsschnitt dargestellt.In the drawing, such a pen is shown in Fig. R in a View and through A # bb. 2 shown in a longitudinal section.

Die Bleimine a befindet sich innerhalb. der Schreibstifthülse in der drehbaren Minenhülse h und wird gegen Verschiebung in Achsenrichtung durch Verwinden einer Schraubenfeder c festgehalten. Diese Feder c sitzt mit ihrem rückwärtigen, Ende an der Minenhülse h. Das vordere Ende der Feder c ist in einer metallenen Schutzhülse b festgelegt, welche auf dem vorderen Ende- der Schreibstifthülse e sitzt. Das- Festhalten der Bleimine a mittels der Feder c wird dadurch herbeigeführt, daß .man die Minenhülse h entgegen der Wicklungsrichtung der Feder c verdreht. Hierzu wird die Hülse h fest mit einer Kappe g verbunden, welche in sonst bekannter Weise auf dem rückwärtigen Bleistiftende derart drehbar sitzt, daß ihre Drehbewegung mittels eines Schlitzes i und. eines Anschlag- und Sperrstiftes f entsprechend begrenzbar ist. Um die Hülse la nach dem Anziehen der Feder c an einem selbsttätigen Zurücktreten zuverhinidern, wird der Schlitz i an seinem einen Ende mit einer Rast k versehen, in welche sich der Stift f sperrend einlegt.The lead a is inside. the pen sleeve in the rotatable lead case h and is against displacement in the axial direction by twisting a coil spring c held. This spring c sits with its rear, End of the lead case h. The front end of the spring c is in a metal protective sleeve b determined which sits on the front end of the pen sleeve e. That- Holding the lead a by means of the spring c is brought about that .man the lead sleeve h is twisted against the winding direction of the spring c. This is done the sleeve h firmly connected to a cap g, which in otherwise known manner the rear end of the pencil is rotatably seated in such a way that its rotational movement by means of of a slot i and. a stop and locking pin f can be limited accordingly is. To the sleeve la after tightening the spring c on an automatic step back zuverhinidern, the slot i is provided at one end with a detent k, in which the pin f is inserted in a locking manner.

Die Feder c liegt an dem vorderen Bleistiftende, um die Bleimine möglichst restlos aufbrauchen zu können. Die Feder c kann mit der Hülse k aus einem Stück hergestellt werden.The spring c is at the front end of the pencil, around the lead if possible to be able to use up completely. The spring c can be made in one piece with the sleeve k getting produced.
