"Retractable ballpoint pen old gqgJBderillung aa main body, Front and back made of metal ".

In recent times there has been a great deal on the 3ohreibwarenmarkt a writing instrument became known, in which by Dauok on a Druokkäppchen aa rear part of the ballpoint pen, the lead ready to write appears at the tip and by further pressure on that cap, the lead is transported back into the housing will.

The housing of these so-called pressure ballpoint pens consists of two parts. The two parts, front part and rear part, are mostly old screw threads screwed together. Intermediate pieces are arranged on the rear part of the housing body as well as on the front part, which are firmly connected to the sleeves. They allow the front part and rear part - housing body to be screwed together. the Seats buses are firmly connected with the corresponding sleeves. This is generally done by gluing, pinning, Riveting and the like.

This arrangement is expensive and it was natural to look for a solution which achieves the same effect, but in terms of manufacture is much simpler and more practical. This innovation is the subject of the present invention.

The retractable ballpoint pen consists of a conical front part 1 and a rear part 2, in which the printing mechanism with the pressure pin 7 is arranged at the rear end. In this back one Housing part, a clip 12 is arranged in a known manner. At the front end of this rear sleeve, verdeokt by the clip, is a Arranged push-in nose which engages in a corresponding groove at the rear end of the front part 3 of the housing. To connect of the front part of the housing and the rear part, the rear part is screwed onto the groove 3 with the nose 4. Inserts on the rear part of the housing and on the front part of the housing to screw together are no longer necessary.

This arrangement means essential progress because Production can be done in the simplest possible way. The production dea housing-body-front parts »with grooves can be used in Uetall as well as in plastic happen, also like the production

the rear housing sleeve.

A much cheaper coaent is also the fact that the Impression grains aa housing rear part 4, which in the

of the front part 3? is £ matures. is covered by the clip 12. so seems invisible.

You arrangement of the mine la housing front part is common already known, also the arrangement of the printing mechanism in the rear part of the housing. It is recommended to decorate the housing body to arrange a corresponding groove at the top of the front part of the housing. There is also a corresponding groove on the rear part of the housing. They arrange a grooving or Cuilloohierung on the housing front part tip bu is especially recommended because this makes the pen in question more easy to grip and grip more firmly.
