Abstract

The invention relates to a ballpoint pen having a fixed refill which is arranged centrally in the longitudinal direction, an automatically acting device being incorporated in the ballpoint pen casing and reliably preventing soiling due to contact when the writing implement is not being used.

Description

Im Bereich der Druckstücke 4 sind an der Hülse 2 ringförmig ausgebildete Ausnehmungen 3 vorgesehen, die jeweils Schrägen 13 aufweisen die wiederum zur Schreibspitze 6 hin geneigt angebracht sind. Wird der Kugelschreiber in Schreibposltion im Normalfall durch Daumen, Zeigefinger und Mittelfinger ergriffen, üben diese Flnger einen Druck auf die Druckstücke 4 aus und bewegen diese nach innen. Die Druckstücke 4 treffen hierbei aul die Schrägen 13 im zurückliegenden Teil der Hülse 2 auf und verschieben diese entgegen der Kraft der leder 5 nach hinten, so daß der vordere Bereich der Hülse 2 die Schreibspitze 6 freigibt (Fig. 2). In the area of the pressure pieces 4, 2 are annularly formed on the sleeve Recesses 3 are provided which each have bevels 13 which in turn face the writing tip 6 are attached inclined. If the ballpoint pen is normally in the writing position gripped by the thumb, forefinger and middle finger, these fingers exert pressure on the pressure pieces 4 and move this inward. The pressure pieces 4 here aul meet the bevels 13 in the rear part of the sleeve 2 and move this against the force of the leather 5 backwards, so that the front Area of the sleeve 2, the writing tip 6 releases (Fig. 2).

Anstelle der in den Zeichnungen dargestellten kugelförmig ausgebildeten Druckstücke 4 lassen sich In den Bohrungen 12 auch zylindrische Druckstücke 4 vorsehen wobei Ansätze 10 in den Bohrungen 12 ein Herausfallen der Druckstücke 4 verhindern. In Abwandlung der Druckstücke 4 lassen sich auch über den Umfang des Kugelschreibergehäuses I verteilt Kreissegmentstücke in ein oder mehreren Reihen vorsehen die in entsprechenden Ausnehmungen 12 geführt und gegen Herausfallen gesichert sind. Bei Bedarf lassen sich die einzelnen Druckstücke 4 miteinander verbinden, z. B. über Stege oder Brücken, wobei die Verbindung in Umfangsrichtung oder auch der einzelnen Reihen untereinander erfolgen kann, so daß z. B. auch eine großflächige Fingerauflage entsteht. Instead of the spherical shape shown in the drawings Pressure pieces 4 can also be provided with cylindrical pressure pieces 4 in the bores 12 lugs 10 in the bores 12 preventing the pressure pieces 4 from falling out. In a modification of the pressure pieces 4 can also be over the circumference of the ballpoint pen housing I distributed segment of a circle pieces in one or more rows provide the appropriate ones Recesses 12 are guided and secured against falling out. Leave if necessary the individual pressure pieces 4 connect to each other, for. B. over footbridges or bridges, the connection in the circumferential direction or also between the individual rows can be done so that z. B. also creates a large finger rest.

Anstelle einer Kugelschreibermine lassen sich auch andersartige Schreibminen mit gleicher vorteilhafter Wirkung der Hülse 2 einsetzen. Auch ist am hinteren Schaft des Kugelschreibergehäuses 1 eine an sich bekannte Werbefläche 9 vorhanden, so daß sich ein erfindungsgemäß ausgebildetes Schreibgerät ohne weiteres an den ästhetischen Geschmack der Käufer und die Bedürfnisse der Industrie anpassen läßt. Instead of a ballpoint pen refill, other types of writing refills can also be used Use the sleeve 2 with the same advantageous effect. Also is on the rear shaft the ballpoint pen housing 1 has a known advertising space 9 so that a writing instrument designed according to the invention readily adapts to the aesthetic one Lets customize tastes of buyers and industry needs.

Claims: 1. Ballpoint pen with centrally arranged in the longitudinal direction, fixed shrink sleeve, as it is marked that the writing tip (6) is covered by a sleeve (2) which is in the front position by a spring (5) Is held that in the grip area on the front shaft of the Kugelschrelbergehluses (1) Pressure pieces (4) are provided, and that the pressure pieces (4) when gripped can be moved inwards by the pressure of the fingers and via bevels (13) on the the sleeve (2) arranged underneath it moves against the force of the spring (5), so that the writing tip (6) is released.

2. Ballpoint pen according to claim 1, characterized in that the The sleeve (2) has one or more recesses (3) on its rear part, on which the bevels (13) are attached inclined towards the writing tip (6).

3. Ballpoint pen according to claim 1, characterized in that the Recesses (3) on the outer surface of the sleeve (2) are annular.

4. Ballpoint pen according to claim 1, characterized in that the Pressure pieces (4) are designed as balls, which are in bores (12) in the grip area of the ballpoint pen housing (1) are arranged in such a way that the balls with the recesses (3) cooperate.

5. Ballpoint pen according to claim 1 and 4, characterized in that that the pressure pieces (4) are cylindrical.

6. Ballpoint pen according to claim 1 and 4, characterized in that that the pressure pieces (4) designed as circular segment pieces and in corresponding Recesses (12) are performed.

7. Ballpoint pen according to claim 4, 5 and 6, characterized in that that the bores / recesses (12) are provided with a shoulder (10) in such a way that that the pressure pieces (4) are prevented from falling out.

The invention relates to a ballpoint pen with in the longitudinal direction centrally arranged, fixed writing lead.

Such ballpoint pens have the disadvantage that they are not in clothing can be accommodated without being stained by leaking ink will. Attempts have been made to remedy this by putting on a cap. However, this makes handling more difficult, and the cap can be lost and the ballpoint pen can come off the cap, and then the clothes to damage.

Another type of ballpoint pen uses a push mechanism than the one before and must be actuated after writing use to put the mine in the writing position or move it back into the ball screw housing. This type of ballpoint pen too has the disadvantage that soiling of the clothes when inserting and Carrying the writing instrument cannot be ruled out.

It is cumbersome to operate the print mechanism every time leads to this being often forgotten.

The problem arises from this prior art the invention to design a ballpoint pen so that the tip of the lead is only released for writing and is automatically protected against contact when not in use.

The task is according to the characterized features of the claim 1 solved: The main advantage of this is that the ballpoint pen has Non-use excludes contamination by touch without the one to do so Operation of a mechanism or the attachment of protective equipment is required. Another major advantage is its use for writing no additional actuation is required, just by detecting in writing a release of the writing tip takes place. This is of every kind reliably prevented from contamination by leaking writing fluid. The handling of a ballpoint pen designed according to the invention is also simplified and laughs without changing the structure and appearance of such a writing instrument changes.

The subclaims characterize advantageous embodiments of the solution according to the invention wherein instead of a ballpoint pen refill any other Mine type can be used.

After the shaft of the ball pen through the found solution The well-known advertising imprints can also be used in the usual way attach.

An embodiment of the invention is shown schematically in the drawing shown. 1 shows a longitudinal section through the unused ballpoint pen State; Fig. 2 A longitudinal section through the ballpoint pen during use.

A ballpoint pen housing 1 is in a known manner in a front and the rear half and can be screwed together via a screw connection 8.
