Description

Retractable ballpoint pen

■ MiMMMN «

The firing is on writing implements, mainly Ballpoint pens, the writing part of which presses out of your housing (! Rest position) has reached the writing position.

The known writing instruments of this type are by the arrangement of a Drucklmopfas at the end opposite the writing tip relatively unattractive. The push button disturbs the overall effect of the writing implement and is consequently »that it is proportionate must be kept weak and protrudes from the housing, always The weak point of the writing instrument · It often breaks because of this3 after which the writing instrument has become unusable

The aim of the fire is to »beautify writing implements of the above type in their external form, and at the same time make them more reliable and less prone to failure . The upper part of the housing (for example the metal cap) is arranged on the lower part in a displaceable manner. Äüt the upper part is the mechanism that allows the movement of the writing lead, firmly connected, so that by a pressure, respectively. by moving the upper part the line in your writing «respectively. Booing is brought »

The writing lead is brought back from the writing position known from! spring pressure. Moses Peder is not known as before loosely attached to the front part of the housing, but is firmly attached to it connected to the mechanics in such a way »that the spring at the upper end of the movable mechanics tong tube on an adjusting ring or similar and at the lower end of the fixed threaded bushing.

An exemplary embodiment is described below with reference to the drawing ben:

The writing implement drawn in the writing position shows only the parts necessary to understand the fire!

The writing instrument has a two-part housing front part and zv / ar the parts 1) and 2) that are screwed or plugged together are · The division of the front part of the housing makes this easy Replacing the writing lead 3).

File 4) shows the threaded bushing of the mechanism, which is firmly connected (e.g. screwed) to the housing part ^. The movable outer part of the mechanism is the pincer tube 5), which also serves as a writing insert. The pliers tube 5) is made so that the writing lead 3 · ^; holds firmly in this and thus the movement of the tong tube 5) (in writing and rest position) can follow.

The pencil lead 3) is pressed when it is inserted into the pliers tube up to the rear stop (shown in the drawing as a bead 6)), where the lead 3 is then firmly seated. The pliers tube 5) extends ia its extension into the cover nut 7), which it through. Pressing in, screwing or the like is firmly connected. The Beckelnut 7} in turn provides a fixed connection to the upper housing part 9) (e.g. metal cap) with the cover screw S.), which slide on the housing part 2) and with which the pen 37 is now operated via the feed mechanism can * The gate push mechanism can also be attached with another rope that is firmly connected to the upper part.

You compression spring Io), which counteracts the bridging movement by hand, and brings the Üine to rest position, is contrary to the previously known not loosely attached in the front part of the housing, but sits aaek on the mechanical pliers 5). It is limited at its upper end through one. Adjusting ring or similar «In. the figure e.g. the bridge spring has a narrowing at the upper end, which is in. the bead 6) of the pliers tube 5) is tight. At their lower "sin strikes they on the fixed threaded bushing 4) of the mechanics and thus brings the Hechaniksange .6) especially writing lead 3) when triggered from the writing position back to the rest position. However, the compression spring can also be used in the front part of the housing be attached when doing the miss with a Fedex stop ring is executed ..
