Wie sich aus den Figuren der Zeichnungen ergibt, besteht das Schreibgerät in Form eines Kugelschreibers aus einem zweiteiligen Schaft 1, 2, wobei im vorderen Teil 1 die Mechanik für die Bewegung der Schreibminen enthalten ist und der rückwärtige Teil 2 einen Raum aufweist, um beispielsweise eine Stempelmechanik unterzubringen, wie sie in der DE-C 33 40 293 beschrieben ist.As can be seen from the figures of the drawings, the writing instrument in the form of a ballpoint pen consists of a two-part shaft 1, 2, the mechanics for the movement of the writing leads being contained in the front part 1 and the rear part 2 having a space, for example around one To accommodate stamp mechanics, as described in DE-C 33 40 293.

Diese Stempelmechanik kann auch durch ein anderes Funktionsteil, beispielsweise einen Markerstift oder eine andere Einrichtung, ersetzt werden. Dieser die Stempelmechanik aufnehmende Raum ist durch eine verschiebbare Kappe 3 abgedeckt und weist stirnseitig einen nach vorne verlaufenden Klip 4 auf.This stamp mechanism can also be replaced by another functional part, for example a marker pen or another device. This space, which accommodates the stamp mechanism, is covered by a displaceable cap 3 and has a clip 4 running on the front side.

Die Stempelmechanik oder ein anderes Funktionsteil ist mit einem damit verbundenen Haiter 5 über eine entsprechend passende Buchse mit der Schaltkurvenhülse 6 verbunden, welche von einer Schutzhülse 7 umgeben ist.The stamp mechanism or another functional part is connected to a hanger 5 connected thereto via a correspondingly suitable socket to the switching cam sleeve 6, which is surrounded by a protective sleeve 7.

Die in den Figuren 2 bis 5 im Detail dargestellte Führungshülse 8 besteht aus einem zylindrischen Hohlkörper, der an zwei gegenüberliegenden Längsseiten je einen Schlitz 9 aufweist. An der Oberseite weist die Führungshülse 8 ein Gewinde 10 auf.The guide sleeve 8 shown in detail in FIGS. 2 to 5 consists of a cylindrical hollow body, each having a slot 9 on two opposite longitudinal sides. The guide sleeve 8 has a thread 10 on the upper side.

Ferner sind im Innenraum der Führungshülse 8 zwei sich gegenüberliegende Führungsschienen 11 vorgesehen, die um 90° zu den Längsschlitzen versetzt sind. An der Stirnseite weist die Führungshülse 8 zwei kreisrunde Bohrungen 12 auf.Furthermore, two opposing guide rails 11 are provided in the interior of the guide sleeve 8, which are offset by 90 ° to the longitudinal slots. On the front side, the guide sleeve 8 has two circular bores 12.

In die Führungshülse 8 sind von hinten zwei in den Figuren 8 und 9 dargestellte Gleitschieber 13 derart eingesetzt, daß die an den Gleitschiebern nach außen springenden Nasen 14 in den Längsschlitzen 9 laufen und die beiden Gleitschieber 13 mit den an der Unterseite vorgesehenen Aussparungen 15 auf den Schienen 11 aufliegen.In the guide sleeve 8, two slide valves 13 shown in FIGS. 8 and 9 are inserted from behind in such a way that the lugs 14 jumping outward on the slide valves run in the longitudinal slots 9 and the two slide valves 13 with the recesses 15 provided on the underside on the Rails 11 rest.

Die Gleitschieber weisen ferner stirnseitig einen zylindrischen Ansatz 16 auf, auf welchen ein Röhrchen 17 aufgesetzt ist, welches mit seinem vorderen Ende durch die jeweilige Bohrung 12 in der Führungshülse herausragt. Über die Röhrchen 17, die stirnseitig auf beiden Gleitschiebern 13 sitzen, ist jeweils eine Schraubenfeder 18 aufgesetzt, welche die Schieber gegen die Schaltkurve 19 einer in den Figuren 6 und 7 dargestellten Schaltkurvenhülse 20 drückt. Die Schaltkurve 19 der Schaltkurvenhülse 20 weist an der Oberseite einen V-förmigen Einschnitt 21 und ggf. auch an der Unterseite einen derartigen Einschnitt 21 auf.The slide valves also have a cylindrical shoulder 16 on the end face, on which a tube 17 is placed, which protrudes with its front end through the respective bore 12 in the guide sleeve. A helical spring 18, which presses the slide against the switching curve 19 of a switching curve sleeve 20 shown in FIGS. 6 and 7, is in each case placed on the tubes 17, which are seated on the ends of the two sliding slides 13. The switching curve 19 of the switching curve sleeve 20 has a V-shaped incision 21 on the upper side and, if appropriate, also such an incision 21 on the underside.

Die Funktion der Mechanik zur Bewegung der beiden Schreibminen bei dem Schreibgerät gemäß der Erfindung ist dabei wie folgt.The function of the mechanism for moving the two writing leads in the writing instrument according to the invention is as follows.

In der Ausgangsstellung befindet sich ein Gleitschieber in der linken Anschlagstellung, d. h. er stößt mit seiner Nase 14 durch den Druck der Feder 18 gegen den unteren, V-förmigen Einschnitt 21 der Schaltkurve 19 der Schaltkurvenhülse 20 an. Damit ist, wie sich aus Fig. 1 ergibt, die vordere Mine 22, die mit dem Röhrchen 17 verbunden ist, in der im Schafftteil 1 eingezogenen Stellung.In the starting position there is a slide valve in the left stop position, i. H. he abuts with his nose 14 by the pressure of the spring 18 against the lower, V-shaped notch 21 of the switching curve 19 of the switching curve sleeve 20. 1, the front lead 22, which is connected to the tube 17, is in the retracted position in the shaft part 1.

Auf der Rückseite befindet sich der Gleitschieber 13 mit seiner Nase 14 in der oberen, V-förmigen Einkerbung 21 der Schaltkurve 19 an der Schaltkurvenhülse 20. Dadurch befindet sich die damit verbundene Schreibmine 23 in der vordersten Stellung, d. h. die Kugelschreiberspitze der Mine ragt aus dem vorderen Teil 1 des Schaftes heraus.On the back is the slide valve 13 with its nose 14 in the upper, V-shaped notch 21 of the switching curve 19 on the switching curve sleeve 20. As a result, the writing refill 23 connected therewith is in the foremost position, ie. H. the ballpoint pen tip of the lead protrudes from the front part 1 of the barrel.

Um nun einen Wechsel der Schreibminen 22, 23 vorzunehmen, ist es lediglich erforderlich, den Schaftteil 1 gegenüber dem Schaftteil 2 zu drehen. Durch diese Drehbewegung schiebt die Schaltkurve 19 den einen Gleitschieber 13 nach vorne, während der andere Gleitschieber durch die Wirkung der Schraubenfeder 18 zurückgedrückt wird, da seine Nase 14 ebenfalls an der Schaltkurve 19 der Schaltkurvenhülse 20 anliegt. Die Folge davon ist, daß die eine Kugelschreibermine 23 zurückgezogen und die andere Kugelschreibermine 22 aus der Offnung im vorderen Schaftteil 1 in die Arbeitsstellung gebracht wird.In order to change the writing leads 22, 23, it is only necessary to turn the shaft part 1 relative to the shaft part 2. By means of this rotary movement, the switching curve 19 pushes the one slide valve 13 forward, while the other slide valve is pushed back by the action of the helical spring 18, since its nose 14 also abuts the switching curve 19 of the switching curve sleeve 20. The result of this is that one ballpoint pen refill 23 is withdrawn and the other ballpoint pen refill 22 is brought out of the opening in the front shaft part 1 into the working position.

An der Führungshülse ist ferner noch ein V-förmiger Anschlag 24 vorgesehen, um eine Begrenzung der Drehbewegung der Schaltkurvenhülse zu bewirken.A V-shaped stop 24 is also provided on the guide sleeve in order to limit the rotational movement of the switching cam sleeve.

Bei der Längsverschiebung der Gleitschieber liegen diese mit ihrer Außenkontur an der Innenseite der Führungshülse 8 an und gleiten ohne Beeinträchtigung auf den abgesetzten Führungsschienen 11 hin und her. Diese Führungsschienen gewähren somit eine hemmungsfreie Führung der Gleitschieber und vermeiden ein gegenseitiges Behindern derselben.During the longitudinal displacement of the slide valves, these lie with their outer contour on the inside of the guide sleeve 8 and slide back and forth on the offset guide rails 11 without impairment. These guide rails thus ensure an unrestricted guidance of the slide valve and avoid mutual hindrance of the same.

In der Schaltkurvenhülse ist ferner eine Bohrung 25 vorgesehen, die mit einer Bohrung in der Schutzhülse 7 zur Dekkung gebracht werden kann, wenn mittels einer Spezialzange die Führungshülse 8 aus der Schaltkurvenhülse 20 ohne Beschädigung herausgezogen werden soll.A bore 25 is also provided in the shift cam sleeve, which can be covered with a bore in the protective sleeve 7 if the guide sleeve 8 is to be pulled out of the shift cam sleeve 20 without damage using special pliers.

Dadurch, daß die Gleitschieber mittels zweier Druckfedern gegen die Schaltkurve 19 der Schaltkurvenhülse 20 gedrückt werden, benötigt man hinter den Minen 22, 23 sehr wenig Platz, so daß ein ausreichend großer Raum zur Vorsehung von Zusatzeinrichtungen, wie z. B. Stempelmechaniken, Faserschreiber od. dgl., entsteht.Because the slide valves are pressed against the switching curve 19 of the switching sleeve 20 by means of two compression springs, very little space is required behind the leads 22, 23, so that a sufficiently large space for the provision of additional devices, such as, for. B. stamp mechanics, fiber pen or the like.

Mit dem Schreibgerät gemäß der Erfindung wird der wesentliche Vorteil erzielt, daß im Unterschied zu den bekannten Schreibgeräten mit Mehrfachminen eine kurze Bauweise der Mechanik erzielt wird.With the writing instrument according to the invention, the essential advantage is achieved that, in contrast to the known writing instruments with multiple leads, a short mechanical construction is achieved.
