Description

welches aus Blech hergestellt und auf einer Hülsenformmaschine geformt ist, verwendet. Das Anrollen bzw. Bördeln des Zwischenstückes zum Zweck der Befestigung mit dem Minenrohr reicht aus, um dem Schreibdruck ohne Beschädigung der Hülse widerstehen zu können.which is made from sheet metal and on a sleeve forming machine is shaped, used. The rolling or flanging of the intermediate piece for the purpose of Attachment to the lead tube is sufficient to withstand the writing pressure without damaging the sleeve to be able to.

Durch die Erfindung wurde also eine Kugelschreibermine geschaffen, welche sowohl für Schreibstifte der eingangs erwähnten Art als auch für Druckstifte geeignet ist. Man ist also in der Lage, herkömmliche Schreibpatronen bzw. Minen zu verwenden, anstatt Spezialpatronen mit abgesetzter Metallschreibspitze einsetzen zu müssen, also Schreibspitzen, welche in Stiften mit zurückziehbarer Spitze nicht verwendet werden können.The invention thus created a ballpoint pen refill which can be used for both pens of the type mentioned as well as for pressure pins is suitable. So you are able to use conventional To use writing cartridges or refills instead of having to use special cartridges with a detached metal writing tip, i.e. writing tips, which cannot be used in retractable tip pens.

In F i g. 3 der Zeichnungen ist eine Kopfansicht einer Hülse 10 a dargestellt, welche aus Kunststoff oder aus einem anderen, billigen Material besteht, das schwächer ist und leichter bricht als die teueren Kunststoffe. Um trotz Verwendung billiger Kunststoffe oder vergleichbarer Materialien einen guten Sitz des Zwischenstückes zu erreichen, wird nach einer zweckmäßigen Weiterbildung vorgeschlagen, daß die den zylindrischen Teil des Zwischenstückes umgebende öffnung der Hülse mit sich vorzugsweise in Längsrichtung der Hülse erstreckenden, zusammendrückbaren Rippen versehen ist. Die Rippen 40In Fig. 3 of the drawings is a head view of a sleeve 10 a, which is made of plastic or of some other cheap material that is weaker and breaks more easily than the expensive ones Plastics. To get a good one despite the use of cheap plastics or comparable materials To achieve the seat of the intermediate piece, it is proposed after an expedient further development, that the opening of the sleeve surrounding the cylindrical part of the intermediate piece is preferably carried along with it is provided longitudinally of the sleeve extending, compressible ribs. The ribs 40

ίο können leicht zusammengedrückt werden und verspannen demnach elastisch das Zwischenstück in der Hülse. Für einen Innenwanddurchmesser von 4 mm und eine Hülsenwandstärke von 0,79 mm sollten die Rippen 0,4 mm breit sein und etwa 0,1mm radial von der Hülsenwand vorstehen, was einem Zwischenstück mit einem Durchmesser von 3,9 mm oder etwas weniger Platz bietet. Es sind etwa acht solcher Rippen rund um die Hülsenwand vorgesehen.ίο can be easily squeezed and tightened accordingly elastic the intermediate piece in the sleeve. For an inner wall diameter of 4 mm and a sleeve wall thickness of 0.79 mm, the ribs should be 0.4 mm wide and about 0.1 mm radial protruding from the sleeve wall, which is an intermediate piece with a diameter of 3.9 mm or offers a little less space. There are about eight such ribs around the sleeve wall.
