Description. The innovation relates to a writing instrument consisting

honrt old oinop HüiSS for recording o|no>< Minnnmopha-

nic or writing cartridge with mechanism and removable writing device tip for writing _pens, ballpoint pens or fountain pens*

There are a variety of designs of writing instruments such as pens, ballpoint pens or fountain pens with rotating, sliding or pressure mechanisms, each of which requires different designs of writing instrument sleeves and is not optimally used in terms of space, so that thick writing sleeves are often the result.

The task of the innovation is now to create a slim writing instrument design whose writing instrument sleeve and tip are equally suitable for pencils with lead mechanism, ballpoint pens with large-capacity cartridges and mechanism as well as fountain pens with

Ink cartridges and pump system are suitable«

To solve this problem, the writing instrument according to the preamble of claim 1 is characterized by a connecting ring as an intermediate piece for the writing instrument tip and sleeve with a screwed-in ring shoulder on the back, into which the writing instrument sleeve can be pressed and a thread on the front against a ring stop for screwing on: the writing instrument tip with

'si «ft«

conical outlet, such that the inner diameter of the writing instrument sleeve for accommodating the mechanism or cartridge is the same as that of the connecting ring. The intermediate piece with writing instrument sleeve and tip can be used equally for writing pens, ballpoint pens or fountain pens.

Above all, a connecting ring can serve as an intermediate piece between the writing instrument sleeve and tip for all types of design, with a ring shoulder for the writing instrument sleeve on one side and a thread with a ring stop on the other side for screwing on the writing instrument tip, whereby this connecting ring runs conically from front to back as a transition piece, while on the inside there is a hollow cylinder holder ibi-Wet with the writing instrument sleeve. "' '.

Further details are described below in the drawing using preferred embodiments, namely:

^Fi 9ur 1 a longitudinal section through the intermediate piece as a connecting ring between the writing instrument sleeve and tip, 25

Figures 2 to 4 show the views of a pen and

Ballpoint pen with push mechanism and the view of a fountain pen,

Figures 5 to 7 show the half sections of Fig. 2 to 4 with

the corresponding mechanics.

As can be seen from the drawing in Figure 1,

The connecting ring 1 with a conical shape towards the back has a screwed-in ring shoulder 2 for

for pressing in the writing instrument sleeve 3 and front

a ring stop 4 with applied thread 5 for screwing on the writing instrument tip 6 with conical

Outlet, whereby the interior space 7, as can be seen, is

forms the same cylinder space throughout.

In Figure 2 there is then shown a writing pen with pressure cap 8 and guide tip 9 for the writing lead, and

Figure 3 shows a ballpoint pen with the same pressure cap 8 and writing cartridge tip 10 in writing position, and Figure 4 shows a fountain pen with end cap 12 and writing nib 13 in the blunted sharpener part 14 with plug-in cap 15 to protect the nib.

The corresponding sections are then shown in Figures 5 to 7, namely in Figure 5 a writing pen with pressure mechanism 16 and pressure pin end 17 with pressure tappet 18, which (16) can be inserted into the intermediate piece 1 with device sleeve 3 in the interior 2 from the front, whereby the limited guided pressure cap 8 receives the pressure pin end 17 and the tapered front end 19 with pliers mechanism of the pressure mechanism &iacgr;&ogr; rests against a ring stop 20 in the device tip 6/ for actuating the feed pliers (not visible here) by means of pressure pin 17 via the pressure cap 8 in the tapered guide tip 9 for the lead feed.

Figure 6 shows a ballpoint pen with a large-capacity cartridge 21 and a change mechanism 22 as a pressure mechanism, which is inserted into the intermediate piece 1 with the device sleeve.

can be inserted from the front in the interior 2, whereby the limited pressure cap 8 receives the pressure end as a change mechanism 22 and the tapered front end 23 of the writing cartridge 21 rests against a ring stop 20 in the device tip 6 with the interposition of a return spring 24 to advance the writing cartridge. As is known, the change mechanism 22 engages when advanced and when pressure is applied again to return the writing cartridge 21, it disengages again under the action of the spring 24, whereby the writing tip 10 is advanced or retracted.

Finally, Figure 7 shows a fountain pen with a writing nib 13, whereby the ink cartridge 26 with pump system 27 can be inserted from the front into the intermediate piece 1 with the device sleeve 3 in the interior 2 and the sleeve end 12 is closed. A plug-in cap 15 as spring protection can be plugged onto and locked into the writing instrument tip part 14, in which the ink cartridge 26 with pump system is firmly inserted.

The connecting ring, which serves as an intermediate piece between the device sleeve 3 and the writing instrument tip 6, with a constant inner diameter 7 and a conical shape from front to back, achieves a shift in the center of gravity to the front compared to the slim sleeve and reinforced tip 6, which is advantageous when handling the writing instruments.

Both the pen shown in Figure 5 and the

Ballpoint pen according to Figure 6, the writing instrument tip is designed the same for the push-button pen and ballpoint pen.
