Description

The utility model concerns a ballpoint pen. The known ballpoint pens correspond in diameter and length the dimensions of normal writing implements, but are too big for certain purposes. The normal dimensions are the known ones Ballpoint pens are necessary to accommodate the semi-automatic feed and return device for the writing lead and the to replace the same required Yerschraubungen the To be able to arrange parts of the pen. Especially to be placed in a small notebook or in one small ladies handbag are the well-known ballpoint pens too great. The subject of the utility model meets the needs mentioned.

According to the hiring, the ballpoint pen has one opposite normal writing implements in diameter and in the

ge reduced sleeve, in which evorriclitung as a lead hold a mine clamping sleeve formed by longitudinal slits and bending of the parts separated thereby is attached and wherein on an external thread provided on the latter in front of the front end of the jacket sleeve a hollow tip with, the opening corresponding to the diameter of the pencil lead, is releasably attached. The Ilinen clamping sleeve carries on her The front end has a hanging with the external thread and is arranged with a thickened neck behind it, which is inserted into the Front end of the jacket sleeve fits, soldered to the same. In one between the closed rear ends of the jacket sleeve and the cavity provided in the clamping sleeve is provided with a bar magnet.

Ability to replace the well-known, semi-automatic feed and Büekholvorrichtung for the writing lead the simple clamping sleeve made it possible to make the jacket sleeve of the new ballpoint pen so thin and short shape that same without difficulty in a little Notebook or a small ladies handbag can be accommodated. By against the writing mine in the Diameter resilient clamping sleeve and that of the mine corresponding The pen tip has a diameter of the opening of the ballpoint pen tip and a fixed holder at the back and front so don't wiggle while writing. The mine can be inserted / grounded through the screwed-on tip. To take out the tip is unscrewed, whereby the mine is captured and pulled out of the same against the friction with the clamping sleeve can be. Thanks to the built-in bar magnet, the ball

scribes are held on to all iron parts, e.g. on desk equipment, typewriters, keys, etc. and is thus secured against rolling away and being lost or damaged, and is always tied.

On the drawing, an embodiment of the subject matter of the utility model is shown in 6 figures, which show:

Fig. 1 the assembled ballpoint pen, Fig. 2 its jacket sleeve,

Fig. 3 its tip, each in axial section, Fig. 4 its clamping sleeve,

Fig. 5 his writing lead,

Fig. 6 his bar magnet, each in an external view.

The ballpoint pen has a closed at the back, front open to itself jacket sleeve 1 (Fig. 1 and 2), whose Diameter and length is significantly reduced compared to normal writing implements, for example to one diameter of 5 now and a length of about 100 mm. Instead of normal Semiautomatic pencil feeder provided for ballpoint pens and return device contains the jacket sleeve 1 only one clamping sleeve 2 (Fig. 1 and 4) ♦ Your clamping effect it has the fact that its rear half is divided by longitudinal slots 3 and the local ropes 4 printed inwards are. At its front end, the clamping sleeve 2 has a ring 5 with an external thread 6 and, behind it, a thickened neck 7 on. It is up to the stop of the external thread

ring 5 inserted from the front into the jacket sleeve 1 and with the same soldered to their suitably thickened neck 7 (Fig. 1), protruding from the jacket sleeve 1 in this way Outer ring nut 5 is a hollow pen tip 8 (Fig.3) unscrewed, the front opening 9 in. Its diameter corresponds to the outer diameter of the writing lead 10 (Fig. 1 and 5).

The refill 10 can with the tip screwed on 8 can be inserted into the ballpoint pen through the opening 9 thereof. It gets into the clamping sleeve 2 and pushes its gained through the longitudinal sole seats 3 and pushed inward Part 4 outwards and thereby tensions it around itself the refill 10 is securely in the ballpoint pen held .. In addition, the refill is in the opening 9 or Tip 8 held wobble-free. To replace a mine 10, the tip 8 is removed from the jacket sleeve 1 or the threaded ring 5 unscrewed. As a result, such a large rope of the mine 10 is free that it is securely grasped and against the action of the clamping sleeve 2 can be drawn from the same.

A small bar magnet 11 is housed in the rear part of the jacket sleeve 1.

The pen is held by the bar magnet 11 wherever parts from Elsen are present, e.g. on desk devices, on typewriters or calculators Keys etc. so that it cannot be lost but is always at hand.
