Holder for tube pens

The present invention relates to a holder for tube pens with a tube pen tip screwed into the lower end into which a writing cone provided with keys and with a limited movable drop weight and cleaning wire is screwed or with static friction.

In such Röhrchensohreiberspitzen the writing cones are therefore provided old SchlUsselflachen to unscrew or to these other more easily for cleaning or replacement of writing bowling kit writing tube line width removed from the terminal to liability. This is usually done with the help of a small key "that is attached to the. Attacks key surfaces or with the help of a ring which is placed on the writing cone, a profiling adapted to the base surface being provided in the ring . Such keys have the disadvantage that they can be used as

Individual parts are easily lost and in particular that for A separate tool is required to produce the key.

The present invention has set itself the task of eliminating these disadvantages and the production of this key to simplify.

To solve this problem, a holder for tube pens of the type mentioned above is proposed, which is characterized in that the upper end of the holder shaft is one of the key elbows of the writing cone has adapted recess. The holder shaft is preferably designed in such a way that the upper end of the holder shaft has an opening for receiving the writing cone tip.

This arrangement makes it possible to use the holder shaft of the tube pen itself as a key. This means that no separate key is required, which considerably reduces manufacturing costs , especially since the change in the previous injection molds for the shaft itself does not matter expedient, protrusions in the inner area of the recess to hold the tip of the tube writer and in particular to provide inwardly directed nose-shaped projections.

In the following, the invention will be explained in more detail with reference to drawings be explained; show it:

Stewardship;
Pig. Figure 3 is a top plan view of the upper end of the holder clip according to Pig. 2.

The tube pen consists of a shaft 2, into the lower end of which the tube pen tip h is screwed. An ink storage container 10 is placed on this tube pen tip, while a writing cone 6 is screwed or clamped into the lower part of the tube pen tip 4. In the upper part of the Sehreibkeg-els is a limited movable drop weight 8 with a cleaning wire 9 located on it, which is arranged to be moved back and forth through the actual writing tube 5, which is fitted in the lower part of the writing cone.

To now remove the writing cone 6 from the tubular pen tip 4 to be removed, i.e. unscrewed or released from the static friction, are in the lower part of the writing cone Key area 7 provided.

Qeraäß invention is at the upper end of the shaft 2 one of the Key surface 7 of the writing cone 6 adapted recess 12 provided. The bottom of the recess 12 has an opening 14 so that when the writing cone 6 is inserted, the lower part with the writing tube 5 received unhindered and a proper engagement of the key curse is guaranteed. So that the writing tip has a firm hold in the upper part of the shaft during the cleaning process, there are two opposing spherical projections 15 are provided.

Dl · Handling takes place in such a way that for cleaning or for Exchange of the writing cone, for example with a writing cone with a writing tube with a different line width, the entire tubular pen tip including the attached one Cartridge is unscrewed from the holder shaft 2, after which the upper end of the holder shaft 2 is placed on the writing cone and this is pushed into the recess 12 and held by the projections 15 that the Key surface 7 of the writing cone 6 with the adapted Engaged recess. Then the writing cone is unscrewed from the pen tip and can For example, they can be cleaned under running water without having to pinger while holding the writing cone dirty. Unscrewing the writing cone

from the tube pen tip is made much easier. Specifically, when the Oewinde has SiOH added by dried ink residues.

Of course, instead of the nose-shaped projections another clamping or screwing device can also be used.
