Description

Multiple point pens, in particular multiple color ballpoint pens

The invention relates to a multiple writer, i.e. a writing instrument with several, mostly different colored Writing refills, in particular ballpoint pen refills, are stored longitudinally in the egg housing and by means of a printing mechanism optionally in locked writing and Rest positions can be transferred.

The Sohreibminen protrude with air into a lower one that covers them cap-like shaft part and can both in the rest position of all mines and / writing position of a mine butt against each other laterally or against the inner wall of the lower part of the shaft and thereby disturbing Elappergeräusohe bring forth.

To prevent this, a plastic slide bar has already been arranged in the center line & * ■ <* Sohaftteileea

This arrangement has the disadvantage that "with inaccurate dimensioning of the sliding rod or its sliding head and as a result of wear and deformation of these ropes between the writing leads and the inner wall of the lower shaft part as much Game exists or arises that the mines can hit the shaft part or soles against each other. The rattling noises are therefore not heard in the known design Security and not prevented for the long term.

In addition, the honing of the sliding bar is close to the printing mechanism or their housing causes difficulties.

The invention aims at avoiding the Haohteile the known arrangement of the multiple writer in such a way that the rattling noises can be prevented easily and safely will.

In contrast to acquaintances * in whom the writing leads spread apart are, according to the invention, the writing leads by an inside the lower, they receiving, cap-like Shaft part arranged device in the direction of the center line ssusamaen. This design has the advantage that it reliably prevents the writing leads from hitting the inner wall of the lower shaft part and that any accuracy of the device and its potential

Wear and deformation have a detrimental effect. Its installation in the shaft part is technically simple and without To carry out disturbance of the pressure mechanics.

These tortelles occur above all when, according to the most essential feature of the invention, the device holding the pencil leads together is an elastic pressure member that encompasses the pencil leads.

In the simplest way, the invention can be realized that a band or as an elastic pressure member Ring made of rubber /> the flexible plastic is used » With the right choice of material, aging and brittleness of the elastic band or bing is not or hardly to be expected. Should it happen, a replacement is possible simple·

Generally, the elastic band or the elastic Do not ring when moving a lead into the writing position taken downstairs, but rather held in place by the rest of the typewriter refills.

To the wandering of the elastic pressure member with a In a further development of the invention, the printing element can be used as an up to prevent refill with greater security to the inner wall of the lower part of the shaft, a ring made of elastic rubber or plastic that rests against it, in particular made of foam rubber or plastic. Here, the pressure member is due to the between him and the inner wall of the lower shaft part occurring

You can achieve a good level of security against Terso attacks by that the ring is glued into the lower part of the stick.

The conical attachment point of the sleeve, which is preferably made of plastic, preferably has a wall thickness that decreases towards the center line, in order to achieve a secure, elastic embracing of the yellow mines

That's the way it is For example, it may be useful to put the elastic compression members at the points of passage of the mines with the number and Form these mines to provide appropriate recesses to ensure good guidance and complete security against Seitli to achieve good movements of the mines.
