Multi-color exchangeable pen, in particular - ballpoint pen "

The innovation relates to a multi-color interchangeable pen, in particular - push-cap operated ballpoint pens.

They are multi-color interchangeable pens, in particular - ballpoint pens with a pressure cap which is subject to spring action for actuation and a pressure pendulum suspended in the pen end part, which presses with its front end on the selected end piece of one of the writing material carriers guided in the pen front part against the effect of fire when the pen is in an inclined position and pressure operation brings into writing position and there releasably locks, known. A so-called Weehsel sleeve is used for triggering, which automatically releases the one in the writing position when the next writing medium is brought in. With these known Druckwechsel- ws.ü pens according to the pendulum principle, the suspension and guidance of the pressure pendulum requires an even better solution, so that disturbances due to tilting or getting stuck in the pressure pendulum mechanism are prevented.

These disadvantages are now due to the multi-colored Weehsel pen, in particular, a ballpoint pen according to the firing system, which is characterized by the fact that the printed part is a in a socket guided guide's polygonal especially square rod serves, at the Yorderende a pendulum is mounted, which at the exit of the guide bush, preferably by means of protruding, the middle lobes serving to guide the pendulum in one of the Mine carrier number · * corresponding polygonal opening runs and with it is limited in the deflection and when pressed in an inclined position compulsorily with the respective selected writing medium carrier cooperates. The pendulum bearing takes place in the front end of the polygonal feeding in a recess, which is then made by means of The bottom flap is closed.

In detail, the guide bushing in the slotted sleeve for the Guide pins of the mine carrier with inserted, known per se Replaceable sleeve reach and preferably be made with this from one piece in plastic, making a special rational manufacturing is achieved.

May further the guide bushing in de τ- slit sleeve, a stop ring for the change sleeve to be in front, the Create the Mine beam ends under spring action in the rest position, while the front end of the protective sleeve, a stop ring is introduced for the change sleeve that! Rag to spring suspension

Finally, the guide can slouch at the end for storing the
Return spring for the pressure cap is removed and thus the
Travel limiters are used. :

The multi-color ballpoint pen shown in the drawing (fig. I) consists of the pen casing 1 and the pressure cap 2. In the front pen part, the lead carriers 3 are guided in the slotted sleeve 4 by means of guide heads 5 in wide slots 6 and

The square bar 14 is connected to the end cap 2 by means of a screw 23 using an end ring 22, which serves as a stop for the return spring 2o. The pen jacket 1, which is pushed onto the slit sleeve 4, engages detachably on its pin 24 by means of end slots 25.

Instead of the four-color alternating pen shown and "described here the new pendulum mechanism can also be used with two-, three- or five-color interchangeable pens Find use. Finally, instead of the multi-color ballpoint pen shown with writing cartridges, it goes without saying also kick a multicolor pencil with writing leads, what about the © 3 principle? according to the new printing mechanics nothing changes.
