pen

The innovation concerns a ballpoint pen design, which allows a particularly favorable hold during the writing process.

The known ballpoint pens are usually designed in the outer shaft so that approximately from the middle, or at least from the front third, a slim tapering of the holder shaft can be seen. As it is with the ballpoint pen is a writing instrument that requires a relatively large writing pressure, the barrel of such a ballpoint pen should therefore be held particularly tightly to prevent the hand from slipping in the direction of the writing tip.

The innovation has now set itself the task of one To create ballpoint pens that do not have this disadvantage. This is achieved in that the shaft is made so conical that it is at the end on the tip side has the thickest point, and thereby the holding pressure and the friction between the shaft and the fingers automatically is reinforced. Particularly favorable conditions can also be achieved in that the. thickened end of the shaft a corrugation or roughening having.

In this novel embodiment, the Center of gravity of the ballpoint pen as far as possible Relocated to the front of the writing tip, which makes the hand position particularly convenient.

In the drawing, the hiring is shown in two exemplary embodiments and then explained in more detail.

It shows:

Ig. 1 a long barrel ballpoint pen according to FIG
Hiring in view,

Pig. 2 the Yord part of the subject of the Pig. 1 in Longitudinal section,

Pig. 3 shows a retractable ballpoint pen according to the control in view and FIG

Pig. 4 the front part of the subject of the pig. 3 in Longitudinal section.

The barrel ballpoint pen according to Pig. 1 consists of the tapered shaft 1, the one at the front end on the writing side has a corrugation 1, the relatively short, conical tip part 2 and that in this tip part inserted ballpoint pen cartridge 3

The conical tip part 2 carries according to Pig. 2 a cylindrical extension 2 ¹ , which is inserted into the long, conical holding shaft 1 with a friction fit. The tip 3 'of the ballpoint pen refill is provided in the usual way with a groove for easier pulling out of the shaft.

The ballpoint pen according to FIG. 3 consists of the conical shaft 4 with the corrugation 4 * »the conical 5 ”tip with a 5"> tip sleeve the ballpoint pen refill 6 and a printing mechanism, not shown in the drawing, located inside the shaft with the Push button 8 protruding from the shaft 4. The shaft 4 advantageously carries a retaining clip The tip 5 is here by means of a threaded shoulder 5 'in Shank 4 screwed in, being inside the tip at the same time the storage for the return spring 7 is provided. The ballpoint pen tip 6 'is in the usual way educated.

The conical shape of the holding shaft (1 or 4) with the corrugation or roughening (I ¹ or 4 ') can be clearly seen from the two FIGS. At the same time, the favorable center of gravity effect is fully evident from these two figures.

Claims (3)

1.) Stick or pressure pen, characterized in that that the shaft (1,4) is so conical that it has the thickest point at the tip end and thus enables the user to have a particularly good hold. 2.) stick or retractable ballpoint pen according to claim 1, characterized in that the taper of the conical shaft (1,4) is about 1.5 ° and the thickened end of the shaft (1,4) has a corrugation or roughening (l ^f , 4 '). 3.) stick or retractable ballpoint pen according to claim 1 or 2, characterized in that the writing tip (2.5) in the shaft (1.4) can be inserted (2 ¹ ) or screwed (5 ¹ ) is arranged. ■ The applicants A. ¥.
