Writing implement

The innovation relates to a writing instrument with a writing element designed as a wick, which extends in its longitudinal direction is resiliently displaceable in the housing of the writing instrument. With those lately In writing implements that have become known, the wick consists of a synthetic fiber bundle impregnated with synthetic resin, e.g. a, us nylon «Such a - ^ ocht ka, nn with a proportionate be provided with a thin drawn tip, so that the typeface produced with such a writing organ is comparable to that of a fountain pen.

In a known writing implement that mentioned at the beginning Art falls to the pen the only task, the writing wick to hold in its foremost position. The tension of the nib is so great that the writing wick becomes too tight Do not push back under normal writing pressure (generally between about 100 and 300 g) lets ο the spring so has no influence on

the writing properties of the writing wick. In the well-known lall, everyone should rather only ensure that even with any tolerances of the writing material containing and at its front end the writing wick-carrying cartridge of the writing wick always with the same Length from the writing instrument housing hera, usra, gt.

In the case of the known writing implements with the aforementioned wick, there is the disadvantage that when the writing pressure is strong, the fine wick tip is pushed apart and thus in
a brush-like writing tip is transformed that
then the desired fine, sharply delimited smear on the writing surface is no longer created.

Starting from the known fiber-tip pen with a resilient mounting of the writing wick, this laughable part is eliminated by the fact that the spring constant of the spring
between 50 and 600 g / cm and their bias between
0 and 400 g lies »When using these empirical values, it is sufficient to laugh at the wick with strong writing pressure to avoid the aforementioned damage to the wick tip.

In the individual case, the spring constant and the
set pre-tension according to the strength of the writing wick used

The innovation is described below with reference to the exemplary embodiments shown in the drawing "wrote en. Show it?

FIG. 1 shows a longitudinal section through the writing instrument according to the invention, with the spring a, uf one in the instrument housing presses stored storage wick,

FIG. 2 the one provided in the writing implement according to the invention Device for changing the preload of the spring and

Figure 3 is a longitudinal section through another embodiment the innovation, whereby the spring presses on a cartridge housed in the device housing.

In the drawing, parts that correspond to one another are provided with the same reference numerals =

The writing wick labeled 1, the a.us a synthetic resin soaked Consists of a bundle of synthetic fibers and is drawn out to a thin point at its front end easily displaceable in the conical tip 2 of the writing instrument in the direction of the longitudinal axis of the writing instrument out and connected in the embodiment of Figure 1 to a storage wick 3, which is loose in the shaft

4 of the writing instrument housed and is therefore also displaceable in this in the axial direction. The storage wick 3 is soaked with the writing fluid (ink) which, as a result of the compared to the storage wick 3 pronounced capillarity of the writing wick 1 is carried away into this and to its writing tip. to For this purpose, the Kapilla.räume the writing wick 1 are made much narrower than those of the storage wick 3 ο

In the rear part of the writing instrument housing a spiral spring 5 is housed, which is at one end against the storage wick 3 a / b based and thus also on the Wick 1 works. The advance of the writing wick 1 is limited by a firmly pressed-on stop disk 6 or the like. At its other end, the spring 5 is supported against a closing element 7 at the rear end of the writing implement a, b.

To the bias of the spring 5 depending on the To be able to change the respective properties of the writing wick 1, in the exemplary embodiment shown in FIG Shank 4 connected. By adjusting the closing element 7 in the axial direction of the housing, the voltage the leather 5 can be enlarged or reduced.

In the embodiment of Figo 3, the spring pushes onto a cartridge mounted in the housing 4 longitudinally displaceable 9, which is drawn out at its front end to a tube 9 ', which is the border for the writing wick 1 forms »

In all the exemplary embodiments, the spring constant and the preload of the spring is such that the writing wick 1 More or less give in due to a relatively strong writing pressure due to the movable storage can.

The innovation is applicable in the context of all individually or in any combination related features the claims for protection as well as the description and the drawing, which are obviously new and progressive to a person skilled in the art.
