Abstract

A method for the production of a writing point for liquid ink by utilizing a tube (5) of small internal diameter and a writing point which is produced thereby are proposed. In such a case, axially extending ink channels (3) are provided in the internal wall of the fixed tube (5) having an internal diameter which substantially corresponds to the diameter of a ball (1), said channels (3) extending to the free end of the tube (5) and being spaced from one another. A circumferential, annular recess (9) is formed in the tube (5) at a distance from the free end of said tube, and the ball (1) is inserted into the free end until it abuts against the recess (9). Subsequently, the free edge of the tube (5) is inwardly flanged, and a substantially cylindrical ink conductor (4) is inserted into the remote end of the tube and partially overlapped by the ink channels (3).

Description

Die Erfindung betrifft eine Schreibspitze mit Kugel für Flüssigtinte, mit einem Rohr geringen Durchmessers, in welchem eine der Kugelanlage dienende Einbuchtung vorgesehen ist, wobei die Kugel zwischen der eine Kugelauflagefläche bildenden umlaufenden Einbuchtung und einem einwärts gebogenen Rand am freien Ende des Rohres gehalten ist, und wobei in dem Rohr, welches mit Ausnahme der umlaufenden, im Schnitt zylindrischen Einbuchtung durchgehend gleichen Durchmesser aufweist, ein dessen Innenraum im wesentlichen ausfüllender Tintenleiter und Tintenkanäle vorgesehen sind, welche im vorderen Bereich des Rohres in dessen Innenwand zueinander parallel und im Abstand voneinander verlaufen.The invention relates to a writing tip with ball for liquid ink, with a tube of small diameter, in which an indentation serving for the spherical system is provided, the spherical being held between the circumferential indentation forming a spherical bearing surface and an inwardly curved edge at the free end of the tube, and wherein in the tube, which has the same diameter with the exception of the circumferential, cylindrical cut-in recess, the interior of which is essentially filled with ink conductors and ink channels, which run parallel to and at a distance from one another in the front region of the tube in the inner wall thereof.

In der Europäischen Patentanmeldung 0 066 541 ist ein Verfahren zur Herstellung einer mit flüssiger Tinte gespeisten Kugelschreiberspitze beschrieben, bei welchem als Ausgangsmaterial von einem Röhrchen mit einem Innendurchmesser von 1 mm ausgegangen wird. Dieses Röhrchen wird zur Herstellung der Schreibspitze und zur Aufnahme der Kugel verschiedenen Verformungsstufen unterworfen, wobei insbesondere der Innendurchmesser des Röhrchens im Bereich der Spitze in mehreren Stufen reduziert wird. Dabei ist das freie Ende des Röhrchens elastisch verformt, damit die Kugel von vorn eingedrückt werden kann und die Spitze die Kugel federnd umgibt. Ein Tintenleiter erstreckt sich im Innern des vorderen Abschnitts der Schreibspitze und weist einen axialen Abstand von der Kugel auf. Durch Rotation der Kugel wird aus dem Tintenhalter die Schreibflüssigkeit in einen Raum gesaugt und dann zum Umfang der Kugel geführt. Zur Herstellung dieser bekannten Schreibspitze sind eine Reihe von Arbeits- und Verformungsstufen erforderlich, welche die Schreibspitze insgesamt technisch aufwendig machen, und ein weiterer Nachteil ist darin zu sehen, daß der im Bereich der Kugelauflage in Form von beabstandeten konischen Einbuchtungen vorhandene Raum nicht gleichmäßig mit Schreibflüssigkeit gefüllt ist.European patent application 0 066 541 describes a method for producing a ballpoint pen tip fed with liquid ink, in which the starting material is a tube with an inner diameter of 1 mm. This tube is subjected to various deformation stages in order to produce the writing tip and to receive the ball, the inner diameter of the tube in the area of the tip in particular being reduced in several stages. The free end of the tube is elastically deformed so that the ball can be pressed in from the front and the tip resiliently surrounds the ball. An ink conductor extends inside the front portion of the writing tip and is axially spaced from the ball. By rotating the ball, the writing fluid is sucked out of the ink holder into a room and then led to the circumference of the ball. A number of working and deformation stages are required to produce this known writing tip, which make the writing tip technically complex overall, and a further disadvantage is that the space in the area of the ball rest in the form of spaced conical indentations is not uniform with writing fluid is filled.

In der US-A-4 457 644 ist eine Schreibspitze mit einer Kugel beschrieben, die in einem Rohr, welches vorne umgebördelt ist, mit Hilfe kerbenförmiger Einbuchtungen gehalten ist, welche voneinander beabstandet sind. Dabei ist die Konstruktion so getroffen, daß entweder das Rohr unterschiedliche Dicke aufweist und verschiedenen Bearbeitungsstufen unterworfen ist, um einen Tintenhalter aufzunehmen, oder in das Rohr ist ein weiteres Bauteil, in welchem Tintenkanäle eingearbeitet sind und welches sich bis zum Tintenvorrat erstreckt, eingebracht. Dabei muß das Rohr, wenn es als gleichzeitige Halterung für die Kugel und zur Aufnahme des Tintenleiters dient, unterschiedliche Umfangskonturen aufweisen.US-A-4 457 644 describes a writing tip with a ball which is held in a tube which is flanged at the front by means of notch-shaped indentations which are spaced apart from one another. The design is such that either the tube has different thicknesses and is subjected to different processing stages in order to accommodate an ink holder, or another component in which ink channels are incorporated and which extends to the ink supply is introduced into the tube. The tube, if it serves as a simultaneous holder for the ball and for receiving the ink conductor, must have different peripheral contours.

Bei einer Kugelschreibspitze nach der DE-C-820 254 ist die Konstruktion so getroffen, daß eine Kugelfassung aus einem Rohrstück auf ein weiteres Tintenzuflußrohr aufgesteckt ist, das seinerseits in dem vorderen Ende eines Kugelschreibers gehalten ist. Dabei ist die Kugelfassung aus einem korrosionsbeständigen Material erstellt, wobei das schwachwandige Rohr an der Stelle des Kugelsitzes in seinem ganzen Umfang nach innen eingezogen ist und somit die Kugel über mehr als die Hälfte ihrer Oberfläche vollkommen umschließt, damit die Kugel schon bei niedriger Drehzahl nicht mehr rattern oder holpern kann, so daß ein schlechtes Schriftbild ausgeschaltet ist.In the case of a ballpoint pen tip according to DE-C-820 254, the construction is such that a ball socket from a tube piece is fitted onto a further ink supply tube, which in turn is held in the front end of a ballpoint pen. The ball socket is made of a corrosion-resistant material, with the weak-walled tube at the location of the ball seat being drawn in over its entire circumference and thus completely enclosing the ball over more than half of its surface so that the ball no longer stops even at low speed can rattle or bump so that a bad typeface is switched off.

Nach der US-A-3 904 297 ist eine Schreibspitze so ausgebildet, daß in ein die Kugel haltendes Rohr ein Stab eingeschoben ist, welcher für die Kugel ein Gegenlager bildet. Damit Schreibflüssigkeit zu der Kugel gelangen kann, ist zwischen dem Stab und dem Rohr ein Raum freigelassen. In der Innenwand des Spitzenabschnittes dieses Rohres erstrecken sich eingearbeitete Tintenauslässe, welche mit den Tintenkanälen und der Außenseite der Fassung in Verbindung stehen, so daß der Kugel Schreibflüssigkeit zugeführt werden kann. Diese Tintenzuführung erfolgt allerdings unter Zuhilfenahme technisch aufwendiger Mittel und nicht besonders dosiert, so daß die Gefahr besteht, daß mit dieser bekannten Schreibspitze Striche unterschiedlicher Strichstärke erzeugt werden.According to US-A-3 904 297 a writing tip is designed so that a rod is inserted into a tube holding the ball, which forms a counter bearing for the ball. A space is left between the rod and the tube so that writing fluid can reach the ball. In the inner wall of the tip section of this tube, built-in ink outlets extend, which are connected to the ink channels and the outside of the holder, so that writing fluid can be supplied to the ball. However, this ink supply is carried out with the aid of technically complex means and not particularly dosed, so that there is a risk that strokes of different stroke widths are produced with this known writing tip.

In der FR-A-1 032 475 ist ein Schreibgerät für pastenförmige Schreibmedien beschrieben, bei welchem das Rohr mit Ausnahme der umlaufenden, im Schnitt zylindrischen Einbuchtung durchgehend gleichen Durchmesser aufweist. Der wesentliche Mangel dieser bekannten Anordnung ist darin zu sehen, daß die Tintenkanäle erst mit dem Stauchvorgang in das Rohr eingearbeitet werden können und somit die Schreibspitze technisch sehr aufwendig hergestellt werden muß.FR-A-1 032 475 describes a writing instrument for pasty writing media in which the tube has the same diameter throughout, with the exception of the circumferential, cylindrical section. The main deficiency of this known arrangement is to be seen in the fact that the ink channels can only be incorporated into the tube with the upsetting process and that the writing tip must therefore be produced in a technically very complex manner.

Die der Erfindung zugrundeliegende Aufgabe besteht demzufolge darin, eine Schreibspitze für Flüssigtinte der eingangs umrissenen Art anzugeben, die im Betrieb sicher und wirksam ist, ohne bei ihrer Herstellung technisch aufwendige Mittel einsetzen zu müssen.The object underlying the invention is therefore to provide a writing tip for liquid ink of the type outlined at the outset, which is safe and effective in operation without having to use technically complex means in its manufacture.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Tintenkanäle sich mindestens über den Bereich der Einbuchtung, deren Kontur aufweisend, erstrecken und so lang ausgebildet sind, daß sie auch teilweise den Tintenleiter umgeben.This object is achieved according to the invention in that the ink channels extend at least over the region of the indentation, the contour of which is formed, and are so long that they also partially surround the ink conductor.

Zweckmäßige Weitergestaltungen ergeben sich aus den Unteransprüchen.Appropriate further developments result from the subclaims.

Der wesentliche Vorteil des erfindungsgemäßen Vorschlages besteht darin, daß ein dünnwandiges Rohr mit einem Durchmesser verwendet werden kann, welcher im wesentlichen dem Kugeldurchmesser entspricht, wobei insbesondere durch die Ausbildung der axial verlaufenden Tintenkanäle, welche den weiter hinten im Rohr sitzenden Tintenleiter teilweise überlappen, ein sehr guter Tintenkontakt zwischen Tintenleiter und Kugel gewährleistet ist, so daß mit einem derartigen Schreibgerät Linien gleichmäßiger Strichstärke erzeugt werden können. Darüber hinaus ist die erfindungsgemäße Schreibspitze einfach herstellbar und somit kostengünstig.The main advantage of the proposal according to the invention is that a thin-walled tube with a diameter which essentially corresponds to the ball diameter can be used, in particular due to the formation of the axially extending ink channels, which partially overlap the ink guide located further back in the tube, a very good ink contact between the ink line and ball is guaranteed, so that lines of uniform line width can be generated with such a writing instrument. In addition, the writing tip according to the invention is simple to manufacture and thus inexpensive.

Weitere Vorteile ergeben sich aus der nachfolgenden Erläuterung der Erfindung an einem Ausführungsbeispiel anhand der beigefügten Zeichnung.Further advantages result from the following explanation of the invention using an exemplary embodiment with reference to the attached drawing.

In der Zeichnung zeigen:

  • Fig. 1 eine Schnittansicht eines Rohres, in dessen Innenwand axial verlaufende und um den Umfang verteilte Tintenkanäle eingearbeitet sind,
  • Fig. den Rohrabschnitt nach Fig. 1 nach dem Einrollen,
  • Fig. eine Schnittansicht der vollständigen Schreibspitze.
The drawing shows:
  • 1 is a sectional view of a tube, in the inner wall axially extending and distributed around the circumference ink channels are incorporated,
  • 1 after rolling up,
  • Fig. Is a sectional view of the complete writing tip.

Wie in Fig. 1 gezeigt ist, wird zur Herstellung der Schreibspitze ein dünnwandiges Rohr 5 mit einem Innendurchmesser von etwa 0,51 mm eingesetzt. In dem vorderen Bereich, welcher später als Kugelaufnahme dient, sind in der Innenwand des Rohres 5 umfangsmäßig beabstandete, sich axial erstreckende Nuten bzw. Kanäle 3 ausgebildet, die insbesondere so hergestellt werden, daß das Rohr 5 in einer Spannzange fixiert und zentriert wird, danach mit einem Stempel in der Form einer Profilnadel mit scharfen Kanten diese Kanäle eingeräumt werden. Mit einem weiteren Stempel wird das aus den Kanälen 3 geräumte Material fortgedrückt und gleichzeitig der Innenumfang des Rohres 5 im Bereich dieser Kanäle 3 entgratet. Im vorderen Bereich des freien Endes des Rohres ist ein Außenkonus 7 vorgesehen.As shown in Fig. 1, a thin-walled tube 5 with an inner diameter of about 0.51 mm is used to produce the writing tip. In the front area, which will later serve as a ball receptacle, circumferentially spaced, axially extending grooves or channels 3 are formed in the inner wall of the tube 5, which are produced in particular so that the tube 5 is fixed and centered in a collet, afterwards with a stamp in the form of a profile needle with sharp edges, these channels are granted. With another punch, the material cleared from the channels 3 is pressed away and at the same time the inner circumference of the tube 5 is deburred in the area of these channels 3. An outer cone 7 is provided in the front area of the free end of the tube.

Wesentlich ist die axiale Länge der Kanäle 3, die sich vom freien Ende des Rohres über eine solche Länge erstrecken, daß später, wenn von der anderen Rohrseite ein Tintenleiter 4 eingesetzt wird, dieser über einen wesentlichen Abschnitt von den Kanälen umgeben ist (Fig. 3).What is important is the axial length of the channels 3, which extend from the free end of the tube over such a length that later, when an ink conductor 4 is inserted from the other tube side, it is surrounded by the channels over a substantial portion (FIG. 3 ).

In Fig. 2 ist eine umlaufende, ringförmige Einbuchtung 9 mit Hilfe eines Werkzeuges 10 eingerollt. Durch diese kontinuierliche Einbuchtung wird eine Kugelauflage 6 geschaffen. Wie deutlich in Fig. 2 gezeigt ist, folgen die Kanäle 3 im Bereich der Einbuchtung der Innenwand des Rohres.2, a circumferential, annular indentation 9 is rolled in with the aid of a tool 10. A ball support 6 is created by this continuous indentation. As is clearly shown in FIG. 2, the channels 3 follow the indentation of the inner wall of the tube.

Zum exakten zentrierten Einbringen der ringförmigen Verjüngung des Rohres im Bereich der Einbuchtung 9 wird in das freie Rohrende ein Stempel 12 eines Werkzeuges 11 eingesetzt, so daß gewährleistet ist, daß die Einbuchtung im Rohr dort eingebracht wird, wo dies erwünscht ist.For the exact centered introduction of the annular taper of the tube in the region of the indentation 9, a punch 12 of a tool 11 is inserted into the free tube end, so that it is ensured that the indentation is introduced into the tube where this is desired.

Fig. 3 zeigt schließlich eine fertig montierte Schreibspitze. Dort ist in den vorderen Abschnitt 2, welcher als Kugelaufnahme dient, eine Kugel 1 eingesetzt, welche an dem Bereich 6 der Einbuchtung 9 anliegt. Das freie Ende des Rohres ist einwärts gebördelt, so daß in diesem Bereich der Rohrdurchmesser geringer als derjenige der Kugel ist. Auf diese Weise wird die Kugel 1 sicher im Rohr gehalten, ohne für das Einbördeln komplizierte Werkzeuge verwenden zu müssen. In das abgewandte Ende des Rohres 5 ist ein im wesentlichen zylindrischer Tintenleiter 4 aus saugfähigem Material so weit eingeschoben, daß sein der Kugel 1 zugewandter vorderer Abschnitt von den Kanälen 3 umgeben ist. Durch diese Überlappung von Tintenleiter 4 und Kanälen 3 ist gewährleistet, daß ein gleichmäßiger kontinuierlicher Tintenfluß von dem Tintenleiter 4 zu der Kugel 1 gewährleistet ist, so daß mit der Schreibspitze Linien konstanter Strichstärke erzeugt werden können.3 finally shows a completely installed writing tip. There, in the front section 2, which serves as a ball receptacle, a ball 1 is inserted, which lies against the area 6 of the indentation 9. The free end of the tube is crimped inwards so that in this area the tube diameter is less than that of the ball. In this way, the ball 1 is held securely in the tube without having to use complicated tools for crimping. In the opposite end of the tube 5, an essentially cylindrical ink conductor 4 made of absorbent material is inserted so far that its front section facing the ball 1 is surrounded by the channels 3. This overlap of ink guide 4 and channels 3 ensures that a uniform, continuous flow of ink from the ink guide 4 to the ball 1 is ensured, so that lines of constant line width can be generated with the writing tip.
