"Working device provided with a cylindrical, smooth outer shape that creates a roll axis, such as ballpoint pens or the like."

The innovation relates to a cylindrical, smooth outer shape that creates a roll axis Tools such as ballpoint pens, mechanical pencils, fountain pens ο the like. In the following, the innovation is explained with the aid of a ballpoint pen, without being a matter of course the innovation is limited to this exemplary embodiment.

With regard to the external shape, essentially three forms of ballpoint pen are known. Once the ballpoint pen that

are equipped with a clip that enables the writing instrument to be held in the pocket or the like. Such Because of the presence of the clip, writing implements cannot rotate about their roll axis on a surface this rotational movement is hindered by the clip.

Ballpoint pens are also known which have a polygonal shape, so that even with such devices, rolling movements are not possible on a corresponding document. Such devices have the disadvantage that often the 'polygonal shape is felt to be disadvantageous in comparison to the round shape. The same goes for devices that are neither polygonal nor round, but for example have an elliptical shape. These devices too cannot roll, but are often difficult to hold.

The third known form are the round ballpoint pens, So where the outer shape defines a roll axis. These devices can be placed on a smooth surface roll and therefore have the disadvantage that especially on the modern, smooth, coated with a plastic layer Desks, these devices can easily make themselves independent and roll off the table. On the other hand, the 'round

Outer shape a shape that adapts well to the hand and that is often required by the writer.

The innovation is based on the task of writing instruments, which are formed on the outside so that they define a roll axis, the outer surface being cylindrically smooth is to prevent the unintentional rolling movement of this writing instrument on a suitable surface.

The problem on which the innovation is based is solved in that the focus is on such a writing implement is placed so that this focus is laterally next to the roll axis. Such an arrangement achieves that outwardly the shape of the writing instrument opposite the previously known, desired shapes do not have to be changed and that despite these smooth, cylindrical, a rolling movement favoring the outer shape the rolling movement even this becomes impossible that the center of gravity of the writing instrument is adjacent to the roll axis, so that the writing instrument can perform a maximum of two or three revolutions even with a corresponding pulse.

According to the innovation, there are several specific embodiments proposed, whereby the procedure is preferably that in the wall of the writing implement on one side an additional

weight is arranged. This additional weight can be created in that the wall of the writing instrument is on one side is thickened or that the wall of the writing instrument is thinned on one side, so that the center of gravity is shifted out of the roll axis.

In further formation of the basic idea, it is further proposed according to the innovation that in the wall of the writing instrument a holder receiving a replacement lead is provided. Of course, it is also possible to use the refill without using a special holder in the hollow writing instrument, which of course also makes the suggestion is realized according to the main claim of the innovation. However, such a realization is most likely to occur Rattling noises in the writing instrument, which are of course undesirable.

In the drawing, exemplary embodiments for solving the problem on which the innovation is based are shown. Here indicates:

Pig. 1 is a diagrammatic representation of a writing instrument, whose outer shape defines a roll axis,

Pig. 2 shows a cross section through a writing instrument with a wall thickened on one side,

Pig, 3 shows a cross section through a writing instrument with a spare refill arranged on one side and

Pig. 4 a writing implement with an additional weight arranged on one side.

In Mg. 1, 1 generally denotes a writing implement, which in the illustrated embodiment consists of two parts 2 and 3, which are connected to one another via the thread 4 are screwed. In the illustration in Fig. 1, part of the writing implement is cut open and it can be seen that the writing instrument is hollow inside and is formed by a relatively thin wall 5. At 6 she is within of the cavity 7 designated mine, which opens at the front of the writing instrument. In Pig. I is with X-X denotes the roll axis, which in the illustrated embodiment is equal to the longitudinal axis of the writing implement is. It can be seen from the illustration without further ado that a writing implement designed in this way in a corresponding Impulse on a suitable surface can cause unwanted rolling movements, if this device is not used is equipped according to the proposal of the innovation. In the illustrated embodiment, part 3 an additional weight 8 used, for example by a small lead ball or the like. can be formed. Pig. 4 the accompanying drawing shows a section according to FIG

• 4 * * ■ 1 1 I / * \

Line 4-4 in Fig. 1 and it can be seen that the additional weight 8 can be inserted into the wall of the writing instrument in the simplest possible way.

In the embodiment according to the sectional structure in Pig. 2 is the wall 5 of the writing instrument on one side "at 9 thickened, so that a shift in the center of gravity of the device from the roll axis is achieved.

In the illustration in FIG. 3, the wall is also thickened and in addition, a bore 10 is provided in the wall, which receives a replacement mine 11, so that thereby the additional weight is reached. Here, in the Bore 10 holding means for the auxiliary mine may be provided, for example those shown in the drawing Bars 12 that clamp the additional mine in the bore and thereby prevent rattling noises.

Of course, the innovation is not limited to the exemplary embodiments shown, but rather they are opposite Changes possible without leaving the basic idea of the innovation, if by relocating the Focus from the roll axis of the device 1 out the rolling movements of the device on a corresponding smooth be prevented.
