Description

Die Erfindung betrifft einen Tintenschreiber mit einem Gehäuse zur Aufnahme von Tintenpatronen oder Tinte und zum Führen des Tintenschreibers und mit einem nicht auswechselbaren Schreibelement, wobei zwischen Tintenvorratsbehälter und einer Lamellengleitspitze ein Kapillarstab angeordnet ist, Kapillarstab und Lamellengleitspitze von einem kegelförmigen, sich zur Lamellengleitspitze hin verjüngenden Kunststoffteil umhüllt sind und die Lamellengleitspitze elastisch gehaltert ist.The invention relates to an ink pen with a housing for receiving ink cartridges or ink and for guiding the ink pen and with a non-exchangeable writing element, a capillary rod being arranged between the ink reservoir and a slat sliding tip, capillary rod and slat sliding tip from a conical plastic part tapering towards the slat sliding tip are encased and the slat sliding tip is elastically supported.

Es ist schon eine Vielzahl von Tintenschreibern mit unterschiedlichsten Ausführungen von Lamellengleitspitzen bekannt. So zeigt beispielsweise die AT-PS 202 897 einen Schreibkörper aus elastischem Material mit einer elastischen Fassung, der aus sektorenförmigen, eng aneinanderliegenden, gegen Verschiebung gesicherten Stäbchen besteht. Die Stäbchen weisen an einem Ende eine Schreibspitze auf und ragen mit ihrem anderen Ende in einen zentralen Kanal des Schreibkörpers, in dem der Tintenvorrat bereitgehalten wird. Die Stäbchen sind in einer zylindrischen Bohrung geführt, die ein gegenseitiges Verschieben der Stäbchen in Längsrichtung verhindern soll. Die Tinte kann erst dann vom Vorratsbehälter zur Schreibspitze fließen, wenn die Schreibspitze mit einem gewissen Mindestdruck auf das Papier gedrückt wird, da erst dann die erforderlichen Kapillaren zwischen den Stäbchen ausgebildet werden. Aufgrund dieser Konstruktion ist nicht immer sichergestellt, daß diejenigen Kapillare, die gerade die Tinte führt, auch auf dem Papier endet, so daß der Schreibvorgang entweder nicht in Gang kommt oder vorzeitig abreißt.A large number of ink pens with different designs of slat sliding tips are already known. For example, AT-PS 202 897 shows a writing body made of elastic material with an elastic holder, which consists of sector-shaped, close-lying rods that are secured against displacement. The sticks have a writing tip at one end and project with their other end into a central channel of the writing body, in which the ink supply is kept ready. The rods are guided in a cylindrical bore, which is intended to prevent the rods from shifting in the longitudinal direction. The ink can only flow from the storage container to the writing tip when the writing tip is pressed onto the paper with a certain minimum pressure, since only then will the required capillaries be formed between the sticks. Because of this construction, it is not always ensured that the capillary that is currently carrying the ink also ends on the paper, so that the writing process either does not start or breaks prematurely.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Tintenschreiber der eingangs genannten Art anzugeben, der bei jedem Schreibwinkel und Schreibdruck eine gleichbleibende Schreibstärke beibehält und eine Lamellengleitspitze besitzt, die nie ausgewechselt zu werden braucht.Based on this prior art, the invention has for its object to provide an ink pen of the type mentioned, which maintains a constant writing strength at every writing angle and writing pressure and has a slat sliding tip that never needs to be replaced.

Diese Aufgabe wird dadurch gelöst, daß die Lamellengleitspitze eine Kugel aus verschleißfestem Material ist, daß die Kugel an das eine Ende eines Schreibrohres geschweißt ist, daß die Kugel und ein Teil des Schreibrohres mehrfach in Längsrichtung kapillar geschlitzt sind, daß das andere Ende des Schreibrohres kegelförmig ausgebildet ist, daß ein Zuführer für Tinte vorgesehen ist, der an seinem vorderen Ende eine kegelförmige Öffnung zur Aufnahme des kegelförmigen Endes des Schreibrohres aufweist, daß der Winkel der Öffnung im Zuführer um einige 100 größer ist als der Winkel des kegelförmigen Endes des Schreibrohres, daß eine Halterung vorgesehen ist, die das Schreibrohr umfaßt, mit dem Zuführer kardanisch beweglich verbindet und seine radial elastische Auslenkung ermöglicht und daß der Kapillarstab vom Tintenvorratsbehälter durch eine zentrale Bohrung des Zuführers und durch das Schreibrohr bis an die Kugel reicht.This object is achieved in that the lamellar sliding tip is a ball made of wear-resistant material, that the ball is welded to one end of a writing tube, that the ball and part of the writing tube are repeatedly capillary slotted in the longitudinal direction, that the other end of the writing tube is conical is formed such that a feeder is provided for ink which has at its front end a tapered opening for receiving the tapered end of the writing tube, that the angle of aperture in the feeder to some 10 0 is greater than the angle of the cone-shaped end of the writing tube, that a holder is provided which comprises the writing tube, gimbally movably connects it to the feeder and enables its radially elastic deflection, and that the capillary rod extends from the ink reservoir through a central bore of the feeder and through the writing tube to the ball.

Durch die Herstellung der Lamellengleitspitze in Form einer Kugel aus verschleißfestem Material, insbesondere aus einer Osmium-Iridium-Legierung ist die Abnützung der Schreibspitze sehr gering, s0 daß das umständliche Auswechseln der Spitze entfallen kann. Außerdem ist die Herstellung von Kugeln aus derartigem verschleißfesten Material eine bereits bekannte und erprobte Technik. Auch ist der Materialaufwand sehr gering, da nur die Kugel aus dem teuren Material hergestellt werden muß, nicht die gesamte Schreibspitze.By producing the lamella sliding tip in the form of a ball from wear-resistant material, in particular from a Osmium-iridium alloy, the wear of the writing tip is very low, so that the cumbersome replacement of the tip can be omitted. In addition, the production of balls from such wear-resistant material is an already known and tried-and-tested technique. The cost of materials is also very low, since only the ball has to be made from the expensive material, not the entire writing tip.

Das Anschweißen der Kugel in das eine Ende des Schreibrohres ist eine kostengünstige, schnelle Verbindungsart; außerdem ist diese Verbindungsart bereits aus der Technik zur Herstellung von konventionellen Schreibfedern bestens bekannt und bewährt. Durch die Verwendung einer Kugel als Schreibspitze und durch die mehrfach vorgesehenen kapillaren Längsschlitze in der Kugel und in einem Teil des Schreibrohres wird unabhängig von der Stellung des Schreibgerätes immer eine gleiche Schriftbreite und Schriftgüte erreicht. Außerdem ist immer eine die Tinte führende Kapillare in direktem Kontakt mit der Schreibunterlage aufgrund der Elastizität der gebräuchlichen Schreibunterlagen und aufgrund der geringen Kugel-0 der Hartkörner, so daß der Tintenfluß beim Aufsetzen der Schreibspitze auf die Schreibunterlage sofort in Gang kommt und auch bei schnellem Schreiben nicht abreißt. Dies wird noch unterstützt durch den Einsatz eines Kapillarstabes im Schreibrohr, der den Tintenfluß vom Vorratsbehälter zur Kugel realisiert.Welding the ball into one end of the writing tube is an inexpensive, fast type of connection; in addition, this type of connection is already well known and proven from the technology for producing conventional nibs. Through the use of a ball as a writing tip and through the multiple provided capillary longitudinal slots in the ball and in a part of the writing tube, the same font width and quality are always achieved regardless of the position of the writing instrument. In addition, there is always a capillary that guides the ink in direct contact with the writing pad due to the elasticity of the conventional writing pads and due to the low ball-0 of the hard grains, so that the ink flow starts immediately when the writing tip is placed on the writing pad and also with fast writing does not tear off. This is further supported by the use of a capillary rod in the writing tube, which realizes the ink flow from the reservoir to the ball.

Es ist bekannt, daß das angenehme Schreibgefüht der herkömmlichen Tintenfüller darauf beruht, daß die Schreibfeder bei Anwendung von Schreibdruck elastisch nachgibt. Schreibgeräte mit starren Schreibspitzen versuchen diesen Effekt allerdings erfolglos dadurch zu imitieren, daß die Schreibspitze in Längsrichtung federnd gelagert ist. Bei der vorliegenden Erfindung, die ja ebenfalls mit einem starren Schreibrohr in der Schreibspitze arbeitet, wird die Elastizität in seitlicher Richtung dadurch erreicht, daß das rückwärtige Ende des Schreibrohres kegelförmig ist und in einer ebenfalls kegelförmigen Öffnung am vorderen Ende des Zuführers für die Tinte federnd und kardanisch gelagert ist. Zu diesem Zweck ist der Winkel des im Zuführer vorgesehenen Kegels um einige 10 0 größer als der Winkel des Kegels am Ende des Schreibrohres.It is known that the pleasant writing experience of the conventional ink fountain pen is based on the fact that the nib yields elastically when using writing pressure. Writing utensils with rigid writing tips try to imitate this effect unsuccessfully by the fact that the writing tip is spring-loaded in the longitudinal direction. In the present invention, which also works with a rigid writing tube in the writing tip, the elasticity in the lateral direction is achieved in that the rear end of the writing tube is conical and also in a cone shaped opening at the front end of the feeder for the ink is resilient and gimbal. For this purpose, the angle of the cone is provided in the feeder to some 10 0 higher than the angle of the cone at the end of the writing tube.

Für die kardanisch bewegliche und dabei unverlierbare Verbindung zwischen dem Schreibrohr und dem Zuführer für die Tinte ist eine Halterung vorgesehen, die das Schreibrohr im Bereich der Kugel und den Zuführer an seinem vorderen Ende umfaßt. Diese Halterung muß so elastisch sein, daß sie eine ausreichende, allseitige, radiale Auslenkung des Schreibrohres erlaubt.For the gimbal-movable and thereby captive connection between the writing tube and the feeder for the ink, a holder is provided which encompasses the writing tube in the region of the ball and the feeder at its front end. This holder must be so elastic that it allows a sufficient, all-round, radial deflection of the writing tube.

Als Halterung dient vorzugsweise eine Manschette aus elastischem Kunststoff. Diese Manschette umfaßt das Schreibrohr an zwei Stellen und zwar im Bereich der Kugel gleitend und im Bereich des kegelförmigen Endes fest. Federt das Schreibrohr radial, so verändert sich das Längenmaß mit dem die Manschette das Schreibrohr umfaßt. Dadurch, daß die Umfassung im Bereich der Kugel nur als schmaler Ringsteg ausgebildet ist, kann er ohne Schwierigkeit auf dem Schreibrohr auf- und abgleiten. Die feste Umfassung des Schreibrohres im Bereich des kegelförmigen Endes dient zur unverlierbaren Befestigung des Schreibrohres am Schreibgerät.A cuff made of elastic plastic is preferably used as a holder. This sleeve encompasses the writing tube at two points, namely in the region of the ball sliding and firmly in the region of the conical end. If the writing tube springs radially, the length dimension with which the sleeve encompasses the writing tube changes. Due to the fact that the encirclement in the area of the ball is designed only as a narrow ring web, it can slide up and down on the writing tube without difficulty. The firm encirclement of the writing tube in the area of the conical end serves for captive attachment of the writing tube to the writing instrument.

Die großen Vorteile dieser Anordnung liegen in der kardanischen Beweglichkeit der Schreibspitze, wobei die Federeigenschaften denen einer herkömmlichen Füllfeder entsprechen, in der Begrenzung des Federweges und im Fehlen einer Verformung des Schreibelementes. Ohne Verformung des Schreibelementes verformen sich aber auch die kapillaren Schlitze in der Kugel nicht, so daß bei allen Schreibdrücken eine immer gleichmäßige Strichbreite erreicht wird.The great advantages of this arrangement lie in the cardanic mobility of the writing tip, the spring properties corresponding to those of a conventional fountain pen, in the limitation of the spring travel and in the absence of deformation of the writing element. Without deformation of the writing element, however, the capillary slots in the ball also do not deform, so that a constant line width is always achieved at all writing pressures.

Die Manschette ist am Zuführer gehaltert. Dabei sind vorzugsweise mehrere treppenartige Absätze an der Berührungsfläche zwischen beiden Teilen vorgesehen. In diesen treppenartigen Absätzen sind gemäß einer bevorzugten Weiterbildung Ringtasehen eingearbeitet, die einen kapillaren Kurzschluß für die Tinte bilden und so verhindern, daß Tinte an der Berührungsfläche zwischen Zuführer und Manschette an die Außenfläche des Schreibgerätes gelangen kann.The cuff is held on the feeder. Thereby are preferred wise provided several stair-like shoulders on the interface between the two parts. According to a preferred further development, ring stake eyes are incorporated into these stair-like heels, which form a capillary short circuit for the ink and thus prevent ink from reaching the outer surface of the writing instrument at the contact surface between the feeder and the cuff.

Vorzugsweise besteht die Manschette aus einem elastischen Thermoplast mit einer Härte Shore A von 85 bis 98. Vorzugsweise können Desmopan R der Lupolen R mit einem Zusatz von Opanol R verwendet werden. Diese Kunststoffe werden von den Firmen BASF in Ludwigshafen bzw. Bayer AG in Leverkusen vertrieben.The cuff preferably consists of an elastic thermoplastic with a Shore A hardness of 85 to 98. Desmopan R of Lupolen R with an addition of Opanol R can preferably be used. These plastics are sold by BASF in Ludwigshafen and Bayer AG in Leverkusen.

An der Berührungsfläche zwischen Manschette und Zuführer ist vorn eine Ringtasche vorgesehen. Die Ringtasche wird dadurch gebildet, daß die Außenseite des Zuführers am vorderen Ende als Kegelstumpf ausgebildet wird. Dadurch wird die Bewegung der elastischen Manschette durch den starren Zuführer nicht behindert.A ring pocket is provided at the front on the contact surface between the cuff and the feeder. The ring pocket is formed in that the outside of the feeder is formed as a truncated cone at the front end. This does not hinder the movement of the elastic cuff by the rigid feeder.

Gemäß einer weiteren Ausbildung der Erfindung ist die Halterung als kegelstumpfförmige Spiralfeder ausgebildet, deren kleine Windungen das Schreibrohr im Bereich der Kugel und deren große Windungen den Außenumfang des vorderen Endes des Zuführers kraftschlüssig umfassen. Zusätzlich wird das vordere Ende des Schreibelements im Bereich der Spiralfeder von einer festen Manschette abgedeckt, die jedoch die kardanisch bewegliche Auslenkung des Schreibrohres nicht behindert. Das Schreibrohr berührt die Manschette erst, wenn der Schreibdruck so groß zu werden droht, daß bleibende Verformungen des Schreibrohres selbst oder des im Schreibrohr geführten Kapillarstabes zu erwarten sind.According to a further embodiment of the invention, the holder is designed as a frustoconical spiral spring, the small turns of which encompass the writing tube in the region of the ball and the large turns of which encompass the outer periphery of the front end of the feeder. In addition, the front end of the writing element is covered in the area of the spiral spring by a fixed sleeve, which, however, does not hinder the cardanically movable deflection of the writing tube. The writing tube only touches the cuff when the writing pressure threatens to become so great that permanent deformations of the writing tube itself or of the capillary rod guided in the writing tube can be expected.

Der Winkel der kegelförmigen Öffnung im vorderen Ende des Zuführers, in dem das Schreibrohr kardanisch gelagert ist, ist um 10 bis 20 o größer als der Winkel des kegelförmigen Endes des Schreibrohres. Erfahrungsgemäß reicht der daraus resultierende Bewegungsspielraum für das Schreibrohr gut aus, um den durchschnittlichen Schreibdruck federnd auszugleichen und ein gleichmäßiges Schriftbild gewährleisten zu können.The angle of the conical opening in the front end of the feeder, in which the writing tube is gimballed, is 10 to 20 ° greater than the angle of the conical end of the writing tube. Experience has shown that the resulting freedom of movement for the writing tube is sufficient to compensate for the average writing pressure and to ensure a uniform typeface.

Vorzugsweise sind die Kugel und das vordere Ende des Schreibrohres mindestens 2-fach längsgeschlitzt. Bei einer 2-fachen Schlitzung sind die Schlitze unter 90 o zueinander angeordnet. In das Schreibrohr reichen die Schlitze etwa um die doppelte Schlitzbreite tiefer als der Durchmesser der Kugel beträgt. Dies führt zu dem schon erwähnten ungestörten Tintenfluß.The ball and the front end of the writing tube are preferably slit longitudinally at least twice. In the case of double slitting, the slits are arranged at 90 o to one another. The slots in the writing tube extend approximately twice the slot width deeper than the diameter of the ball. This leads to the already mentioned undisturbed ink flow.

  • Fig. 4 shows a longitudinal section through a further embodiment of a writing element.

In Fig. 1 erkennt man das Schreibelement, d. h. den vorderen Teil eines Tintenschreibers 8 im Längsschnitt. Ein Zuführer 1 enthält in üblicher Weise OberfluBkammern 1.2., eine Tintenkapillare 1.3. und eine Luftnut 1.4. Die Tintenkapillare 1.3 schneidet im Bereich 1.6 eine zentrale Bohrung 1.5 im Zuführer 1. In diese Bohrung 1.5 ist ein Kapillarstab 4 eingesetzt, der die Tinte aus der Tintenkapilare·1.3 bis zur Schreibspitze leitet. Ist der Kapillarstab als Faserdocht ausgebildet, so kann er mehr Tinte speichern als eine gewöhnliche Kapillarnut in herkömmlichen Tintenschreibern. Dadurch kann auch bei schneller Schreibgeschwindigkeit der Tintenfluß nicht abreißen.In Fig. 1 you can see the writing element, i. H. the front part of an ink pen 8 in longitudinal section. A feeder 1 contains surface chambers 1.2., An ink capillary 1.3. and an air groove 1.4. The ink capillary 1.3 cuts a central bore 1.5 in the feeder 1 in the region 1.6. A capillary rod 4 is inserted into this bore 1.5, which guides the ink from the ink capillary 1.3 to the writing tip. If the capillary rod is designed as a fiber wick, it can store more ink than an ordinary capillary groove in conventional ink pens. As a result, the ink flow cannot stop even at a fast writing speed.

Der Zuführer 1 ist in seinem vorderen Bereich treppenförmig ausgebildet, wobei die vorderste Treppenstufe 1.7 kegelstumpfförmig ist. Dort, wo der Kapillarstab 4 den Zuführer 1 verläßt, ist eine kegelförmige Vertiefung 1.1 eingearbeitet. In dieser Vertiefung 1.1 ist ein Schreibrohr 2 mit seinem kegelförmigen Ende 2.2 gelagert. Aufgrund der Tatsache, daß der Kegelwinkel der Vertiefung 1.1 im vorderen Ende des Zuführers 1 um 10 bis 20 0 größer ist als der Kegelwinkel des Endes 2.2 des Schreibrohres 2, kann das Schreibrohr 2 gegenüber dem Zuführer 1 allseitig kardanisch geschwenkt werden, wobei der Kapillarstab 4, der auch das Schreibrohr 2 bis zu seinem vorderen Ende durchdringt, der Bewegung elastisch folgt.The feeder 1 is designed in the shape of a step in its front area, the front step 1.7 being frustoconical. Where the capillary rod 4 leaves the feeder 1, a conical recess 1.1 is incorporated. A writing tube 2 with its conical end 2.2 is supported in this recess 1.1. Due to the fact that the cone angle of the recess 1.1 of the feeder 1 in the front end by 10 to 20 0 is greater than the cone angle of the end 2.2 of the write pipe 2, the write pipe 2 can be pivoted on all sides gimbal relative to the feeder 1, wherein the Kapillarstab 4 , which also penetrates the writing tube 2 to its front end, follows the movement elastically.

Auf das vordere Ende des Schreibrohres 2 ist eine Kugel 3 aus Hartmetall aufgeschweißt. Sowohl die Kugel 3 als auch das Schreibrohr 2 sind im vorderen Bereich mit kapillaren Schlitzen 3.1 bzw. 2.1 versehen. Die Schlitze 2.1 im Schreibrohr 2 sind etwa um die doppelte Schlitzbreite tiefer als die Kugel 3.A ball 3 made of hard metal is welded onto the front end of the writing tube 2. Both the ball 3 and the writing tube 2 are provided with capillary slots 3.1 and 2.1 in the front area. The slots 2.1 in the writing tube 2 are approximately twice the slot width deeper than the ball 3.

Zur Halterung des Schreibrohres 2 am Zuführer 1 dient eine Manschette 5 aus einem elastischen Kunststoff, die auf treppenförmige Absätze am Zuführer 1 aufgesetzt ist und sich zur Spitze des Schreibelementes hin verjüngt. Die Befestigung erfolgt beispielsweise durch Aufpressen der Manschette 5 auf einen Außenumfang 5.3 des Zuführers 1. In die Berührungsfläche zwischen Zuführer 1 und Manschette 5 sind Ringtaschen 5.2 bzw. 5.1 eingearbeitet, die einen kapillaren Kurzschluß für die Tinte bilden und diese daran hindern, nach außen auf das Gehäuse des Tintenschreibers zu gelangen.A holder is used to hold the writing tube 2 on the feeder 1 Cuff 5 made of an elastic plastic, which is placed on stair-shaped heels on the feeder 1 and tapers towards the tip of the writing element. The attachment takes place, for example, by pressing the sleeve 5 onto an outer circumference 5.3 of the feeder 1. In the contact area between the feeder 1 and the sleeve 5, ring pockets 5.2 and 5.1 are incorporated, which form a capillary short circuit for the ink and prevent it from opening out to get the housing of the ink pen.

Die Manschette 5 umfaßt das Schreibrohr 2 am vorderen Ende 5.691eitend, am hinteren Ende 5.4 fest. Sie nimmt die radiale Komponente des Schreibdruckes auf und ist in ihrer Biegesteifigkeit so bemessen, daß sich eine ähnliche Federelastizität einstellt, wie sie von Schreibfedern her üblich ist. Von besonderem Vorteil ist jedoch, daß sich ein endlicher Federweg einstellt, ohne Deformation des Schreibelementes, während sich eine Füllhalterfeder bis zur bleibenden Verformung verbiegen läßt, so daß dann kein kapillarer Übergang von Tinte aus dem Zuführer in den Federschlitz mehr möglich ist. Auch bei einer maximalen Auslenkung des Schreibrohres 2 erfolgt dank der elastischen Wirkweise des Kapillarstabes 4 ein einwandfreier Tintenfluß, während eine gewöhnliche Füllhalterfeder ab einem bestimmten Schreibdruck auch dann keine Tinte mehr abgibt, wenn die Verformung noch nicht bleibend ist.The cuff 5 comprises the writing tube 2 at the front end 5.6 9 1eit, fixed at the rear end 5.4. It absorbs the radial component of the writing pressure and is dimensioned in terms of its bending stiffness in such a way that a spring elasticity similar to that which is customary with nibs arises. Of particular advantage, however, is that a finite spring travel is achieved without deformation of the writing element, while a fountain pen can be bent to permanent deformation, so that then no capillary transfer of ink from the feeder into the spring slot is possible. Even with a maximum deflection of the writing tube 2, thanks to the elastic mode of action of the capillary rod 4, there is a perfect ink flow, while an ordinary fountain pen no longer emits ink from a certain writing pressure, even if the deformation is not permanent.

Wenn die Spitze des Schreibrohres 2 radial federt, verändert sich das Längenmaß, mit dem die Manschette 5 das Schreibrohr 2 umfaßt. Deshalb ist zwischen Schreibrohr 2 und Innenseite der Manschette 5 ein Bereich 5.5 vorgesehen, in welchem die Manschette 5 das Rohr 2 nicht berührt. Im Bereich der Kugel 3 berührt nur der schmale Ringsteg 5.6 der Manschette 5 das Rohr 2 und kann auf ihm einige Zehntelmillimeter gleiten. Für die feste Verbindung des Schreibrohres 2 mit der Manschette 5 sorgt die Verrippung 5.4 nahe am Kardanpunkt 2.3, d. h. nahe dem kegelförmigen Ende 2.2 des Schreibrohres 2. Der Kopf des Zuführers 1 ist als Kegelstumpf 1.7 ausgeführt mit einem Winkel entsprechend dem Winkel am Ende 2.2 des Schreibrohres 2, um die elastische Verformung der Manschette 5 nicht zu behindern.If the tip of the writing tube 2 springs radially, the length dimension with which the sleeve 5 encompasses the writing tube 2 changes. Therefore, an area 5.5 is provided between the writing tube 2 and the inside of the sleeve 5, in which the sleeve 5 does not touch the tube 2. In the area of the ball 3, only the narrow ring web 5.6 of the sleeve 5 touches the tube 2 and can slide on it a few tenths of a millimeter. For the firm connection of the writing tube 2 with the sleeve 5 the ribbing 5.4 ensures close to the gimbal point 2.3, ie near the conical end 2.2 of the writing tube 2. The head of the feeder 1 is designed as a truncated cone 1.7 with an angle corresponding to the angle at the end 2.2 of the writing tube 2 so as not to cause the elastic deformation of the sleeve 5 to hinder.

Bei einem Blick auf die Spitze de.s Schreibelementes gemäß Fig. 2 erkennt man die Kugel 3 mit zwei um 90 ° versetzten kapillaren Längsschlitzen 3.1. Anstelle einer 2-fachen Schlitzung sind auch 3- und 4-fache Schlitzungen denkbar.When looking at the tip of the writing element according to FIG. 2, the ball 3 can be seen with two capillary longitudinal slots 3.1 offset by 90 °. Instead of a double slit, triple and quadruple slits are also conceivable.

Fig. 3 zeigt, wie bei gleicher Haltung des Tintenschreibers 8 trotz unterschiedlicher Schreibrichtungen A bzw. Bein gleicher Tintenmeniskus 6 bzw. 7 zwischen Kugel und Papieroberfläche 9 gebildet wird. Die erfindungsgemäße Schreibspitze fördert dann auch noch einwandfrei Tinte, wenn der Winkel zwischen Schreibgerät und Papieroberfläche bis auf 100 verringert wird. Der Schreiberfolg ist auch dann gegeben, wenn das Schreibgerät axial rotiert. Bei einem Kugelschreiber beispielweise liegt dagegen der maximal mögliche Schreibwinkel zwischen Geräteachse und Papieroberfläche bei maximal 50 0 und bei einer herkömmlichen Füllhalterfeder ist ein Rotieren des Schreibgerätes nicht möglich, da dann die Feder kratzt. Ein Tintenschreiber mit der erfindungsgemäßen Gleitspitze ist somit in gleicher Weise für Rechtshänder, Linkshänder und Schrägschreiber brauchbar.3 shows how the same ink meniscus 6 or 7 is formed between the ball and the paper surface 9 with the same position of the ink pen 8 despite different writing directions A or leg. The writing tip according to the invention then also delivers ink perfectly if the angle between the writing instrument and the paper surface is reduced to 10 0 . Writing is also successful when the writing instrument rotates axially. In the case of a ballpoint pen, for example, on the other hand, the maximum possible writing angle between the device axis and the paper surface is a maximum of 50 °, and with a conventional fountain pen it is not possible to rotate the writing device because the spring then scratches. An ink pen with the slide tip according to the invention can thus be used in the same way for right-handers, left-handers and oblique writers.

In Fig. 4 erkennt man eine weitere Ausführungsform des Schreibelementes. Hier ist das vordere Ende 1.8 des Zuführers 1 zylindrisch ausgebildet. Eine kegelstumpfförmige Spiralfeder 10 umfaßt mit ihren großen Windungen 10.2 das vordere Ende 1.8 des Zuführers 1, mit ihren kleinen Windungen 10.1 das Schreibrohr 2 im vorderen Bereich. Die Spiralfeder 10 gewährleistet somit sowohl die unverlierbare Befestigung des Schreibrohres 2 am Zuführer 1 als auch seine kardanisch elastische Beweglichkeit. Die Spiralfeder 10 ist von einer festen Manschette 15 abgedeckt, deren vordere Öffnung 15.1 derart bemessen ist, daß für die radiale Bewegung des Schreibrohres 2 genügend Freiraum verbleibt.4 shows a further embodiment of the writing element. Here, the front end 1.8 of the feeder 1 is cylindrical. A frustoconical spiral spring 10 with its large turns 10.2 comprises the front end 1.8 of the feeder 1, and with its small turns 10.1 the writing tube 2 in the front area. The spiral spring 10 thus ensures both the captive attachment of the Writing tube 2 on the feeder 1 and its gimbal elastic mobility. The spiral spring 10 is covered by a fixed sleeve 15, the front opening 15.1 of which is dimensioned such that sufficient space remains for the radial movement of the writing tube 2.
