Abstract

The long extending felt tip for the pen may be fed with ink by capillary action. The writing device can be clamped to the open end of a sleeve-like writing device carrier using tensioning jaws. The tensioning jaws themselves are pressed together by screw-on cover nut and conical surfaces which enclose the writing device and which are supported against the writing device carrier. At least four tension jaws (6, 7, 8) are sections of a holding link (3) made in one piece in which the slots between the tensioning jaws extend only over a part of the whole length of the holding link.

Description

Die Erfindung bezieht sich auf ein Schreibgerät mit einem langgestreckten, saugfähigen, filzartigen Schreibmittel, welches am offenen Ende eines hülsenartigen Schreibmittelträgers mit Hilfe von Spannbacken festklemmbar ist, welche ihrerseits durch eine auf den Schreibmittelträger aufschraubbare Überwurfmutter und an ihren Außenseiten befindlichen konischen Auflaufflächen das Schreibmittel umfassend und sich gegen den Schreibmittelträger abstützend zusammenpreßbar sind.The invention relates to a writing instrument with an elongated, absorbent, felt-like writing medium, which can be clamped at the open end of a sleeve-like writing medium carrier with the aid of clamping jaws, which in turn comprises the writing medium by means of a union nut which can be screwed onto the writing medium carrier and conical running surfaces located on its outer sides can be pressed together to support the writing medium support.

Ein Schreibgerät dieser Art ist bekannt aus der DE-PS 12 96 052. Bei diesem bekannten Schreibgerät sind die Spannbacken sowohl vom Schreibmittelträger als auch voneinander getrennt. Diese Ausführungsform hat den Nachteil, daß der Zusammenbau des Schreibgerätes erschwert ist, weil die beiden voneinander getrennten Spannbacken auf das Schreibmittel gedrückt und dann festgehalten werden müssen, damit die Spannbacken zusammen mit dem Schreibmittel in den Schreibmittelträger eingeführt werden können. Insbesondere wenn das Schreibmittel im Querschnitt größer ist als der lichte Querschnitt zwischen den Spannbacken, macht der Zusammenbau des Schreibgerätes erhebliche Schwierigkeiten.A writing instrument of this type is known from DE-PS 12 96 052. In this known writing instrument, the clamping jaws are separated both from the writing medium carrier and from one another. This embodiment has the disadvantage that the assembly of the writing instrument is difficult because the two separate clamping jaws must be pressed onto the writing medium and then held so that the clamping jaws can be inserted into the writing medium carrier together with the writing medium. Particularly when the writing medium is larger in cross section than the clear cross section between the clamping jaws, the assembly of the writing instrument makes considerable difficulties.

Ein weiterer Nachteil des bekannten Schreibgerätes besteht darin, daß die beiden Spannbacken die Klemmkräfte nur sehr ungleichförmig auf den Umfang des Schreibmittels verteilen. Da sich Maßabweichungen des üblicherweise aus Filz bestehenden Schreibmittels nicht oder nur sehr schwer vermeiden lassen, sind die partiell auftretenden Klemmkräfte bei einem Schreibmittel mit Übermaß extrem groß, während ein Schreibmittel mit Untermaß nicht genügend gehalten wird. Aus diesem Grunde ist es bei dem bekannten Schreibgerät notwendig, auf den Innenflächen der beiden Spannbacken Vorsprünge oder Rippen anzuordnen, die sich in das Schreibmittel hineindrücken.Another disadvantage of the known writing instrument is that the two clamping jaws distribute the clamping forces only very unevenly over the circumference of the writing medium. Since deviations in size of the writing medium, which is usually made of felt, cannot be avoided or can only be avoided with great difficulty, the clamping forces which sometimes occur in the case of a writing medium with an oversize are extremely large, while a writing medium with an undersize is not adequately held. For this reason, it is necessary in the known writing instrument to arrange projections or ribs on the inner surfaces of the two clamping jaws, which press into the writing means.

Aufgabe der Erfindung ist es, ein Schreibgerät der eingangs genannten Art zu schaffen, bei dem das Einsetzen des Schreibmittels zusammen mit den Spannbacken in den hülsenartigen Schreibmittelträger erleichtert ist und bei dem das filzartige Schreibmittel mit über dem Umfang gut verteilten Klemmkräften zuverlässig gehalten wird, auch dann, wenn der Querschnitt des Schreibmittels vom Sollmaß abweicht.The object of the invention is to provide a writing instrument of the type mentioned, in which the insertion of the writing medium together with the clamping jaws into the sleeve-like writing medium carrier is facilitated and in which the felt-like writing medium is reliably held with clamping forces well distributed over the circumference, even then , if the cross section of the writing medium deviates from the nominal size.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß mindestens vier Spannbacken Teile eines einstückigen Haltegliedes sind, bei dem die Schlitze zwischen den Spannbacken sich nur über einen Teil der Gesamtlänge des Haltegliedes erstrecken und abwechselnd von dem dem Schreibmittelträger zugewandten Ende und von dem dem Schreibmittelträger abgewandten Ende des Haltegliedes ausgehen.This object is achieved in that at least four clamping jaws are parts of a one-piece holding member, in which the slots between the clamping jaws only extend over part of the total length of the holding member and alternately from the end facing the writing medium holder and from the end facing away from the writing medium holder Go out holding member.

Die erfindungsgemäße Ausbildung des Schreibgerätes bewirkt, daß das Halteglied leicht über das Schreibmittel geschoben werden kann und zusammen mit diesem Schreibmittel in den Schreibmittelträger eingesetzt werden kann. Da ein Teil der Schlitze an dem dem Schreibmittelträger zugewandten Ende offen sind und ein anderer Teil der Schlitze an dem nach außen gerichteten Ende des Haltegliedes, ist aufgrund der Elastizität des Materials des Haltegliedes der freie Querschnitt zwischen den Spannbacken veränderbar. Es können also auch ohne Schwierigkeiten solche Schreibmittel eingesetzt werden, deren Querschnitt größer ist als der Soll-Querschnitt.The design of the writing instrument according to the invention means that the holding member can be easily pushed over the writing medium and can be inserted into the writing medium carrier together with this writing medium. Since part of the slots are open at the end facing the writing medium support and another part of the slots at the outward end of the holder limb, the free cross-section between the clamping jaws can be changed due to the elasticity of the material of the holding member. It is therefore also possible to use writing means whose cross-section is larger than the target cross-section without difficulty.

Weil das Halteglied mit mindestens vier gleichmäßig über den Umfang des Schreibmittels verteilten Spannbacken ausgerüstet ist, werden die Klemmkräfte erheblich günstiger in das beispielsweise aus Filz bestehende Schreibmittel eingeleitet als bei dem bekannten Gerät. Es wird eine sehr gute Haltekraft bewirkt, ohne daß das relativ weiche Schreibmittel partiell zu stark zusammengedrückt wird.Because the holding member is equipped with at least four clamping jaws evenly distributed over the circumference of the writing medium, the clamping forces are introduced into the writing medium consisting of felt, for example, considerably more favorably than in the known device. A very good holding force is achieved without the relatively soft writing medium being partially compressed too much.

Die Anordnung der Schlitze und der die Spannbacken miteinander verbindenden Stege hat zur Folge, daß beim Aufschrauben der Überwurfmutter sich die Spannbacken über ihre gesamte Länge gleichmäßig an das Schreibmittel anschmiegen.The arrangement of the slots and the webs connecting the clamping jaws to one another has the result that when the union nut is screwed on, the clamping jaws nestle uniformly over the entire length of the writing medium.

In der folgenden Beschreibung wird ein Ausführungsbeispiel der Erfindung unter Bezugnahme auf die Zeichnungen näher erläutert. Die Zeichnungen zeigen in

  • Figur 1 eine Seitenansicht und teilweise einen Längsschnitt des erfindungsgemäßen Schreibgerätes,
  • Figur 2 eine Seitenansicht des Haltegliedes,
  • Figur 3 eine Seitenansicht des gegenüber Fig. 2 um 90° gedrehten Haltegliedes,
  • Figur 4 eine Ansicht von oben auf das Halteglied nach Fig. 2,
  • Figur 5 eine perspektivische Ansicht des Haltegliedes.
In the following description, an embodiment of the invention is explained in more detail with reference to the drawings. The drawings show in
  • FIG. 1 shows a side view and partially a longitudinal section of the writing instrument according to the invention,
  • FIG. 2 shows a side view of the holding member,
  • FIG. 3 shows a side view of the holding member rotated by 90 ° with respect to FIG. 2,
  • FIG. 4 shows a view from above of the holding member according to FIG. 2,
  • Figure 5 is a perspective view of the holding member.

Das Schreibgerät nach Fig. 1 setzt sich zusammen aus einem langgestreckten filzartigen Schreibmittel 1, einem hülsenartigen Schreibmittelträger 2, einem Halteglied 3 und einer Überwurfmutter 4. Das Halteglied 3 weist eine konische Außenfläche 5 auf, die mit einer entsprechend konischen Innenfläche der Überwurfmutter 4 zusammenwirkt. Durch Aufschrauben der Überwurfmutter 4 wird das Halteglied 3 gegen das beispielsweise zylindrische Schreib- 'mittel 1 gepreßt. Dabei stützt sich das Halteglied gegen den Schreibmittelträger 2 ab.1 is composed of an elongated felt-like writing medium 1, a sleeve-like writing medium support 2, a holding member 3 and a union nut 4. The holding member 3 has one conical outer surface 5, which cooperates with a correspondingly conical inner surface of the union nut 4. By screwing on the union nut 4, the holding member 3 is pressed against, for example, cylindrical writing means 1. The holding member is supported against the writing medium carrier 2.

Wie die Figuren 2 bis 5 zeigen, ist das Halteglied 3 einstückig und weist vier Spannbacken 6, 7, 8 und 9 auf, die durch Schlitze 10, 11, 12 und 13 teilweise voneinander getrennt sind. Die Schlitze 10, 11, 12 und 13 erstrecken sich nur über ein Teil der Länge des Haltegliedes 3.As FIGS. 2 to 5 show, the holding member 3 is in one piece and has four clamping jaws 6, 7, 8 and 9, which are partially separated from one another by slots 10, 11, 12 and 13. The slots 10, 11, 12 and 13 extend only over part of the length of the holding member 3.

Die Schlitze 10 und 12 gehen von dem äußeren vom Schreibmittelträger 2 abgewandten Ende des Haltegliedes aus und enden vor einem zylindrischen Kragen 18, der in den Schreibmittelträger 2 einsteckbar ist. Die beiden anderen Schlitze 11 und 13 gehen von dem dem Schreibmittelträger 2 zugewandten Ende des Haltegliedes 3 aus und enden einige Millimeter vor dem äußeren Ende des Haltegliedes. Jede Spannbacke 6, 7, 8 und 9 ist über einen Steg 14, 15, 16 und 17 mit einer benachbarten Spannbacke verbunden. Die Längserstreckung eines Steges beträgt etwa 10 bis 25 % der Längserstreckung des Haltegliedes 3.The slots 10 and 12 extend from the outer end of the holding member facing away from the writing medium carrier 2 and end in front of a cylindrical collar 18 which can be inserted into the writing medium carrier 2. The other two slots 11 and 13 start from the end of the holding member 3 facing the writing medium support 2 and end a few millimeters before the outer end of the holding member. Each clamping jaw 6, 7, 8 and 9 is connected to an adjacent clamping jaw via a web 14, 15, 16 and 17. The longitudinal extension of a web is approximately 10 to 25% of the longitudinal extension of the holding member 3.

Weil die Schlitze 10 und 12 nur bis zum zylindrischen Kragen 18 des Haltegliedes 3 reichen, ist der Querschnitt der Verbindungsstege 14 und 15 genauso groß wie der Querschnitt der Verbindungsstege 15 und 17 an dem dem Schreibmittelträger abgewandten Ende des Haltegliedes 3.Because the slots 10 and 12 only extend as far as the cylindrical collar 18 of the holding member 3, the cross section of the connecting webs 14 and 15 is the same size as the cross section of the connecting webs 15 and 17 at the end of the holding member 3 facing away from the writing medium carrier.

Weil das Halteglied 3 über seine gesamte Länge im freien Querschnitt veränderbar ist, läßt sich das Halteglied 3 ohne Schwierigkeiten auch über solche Schreibmittel 1 schieben, die im Querschnitt größer sind als der Sollquerschnitt. Das Halteglied 3 besteht aus Kunststoff, insbesondere aus dem unter dem Warenzeichen Hostalen bekannten Werkstoff. Das langgestreckte Schreibmittel 1 sowie der das Schreibmittel 1 aufnehmende Innenraum des Haltegliedes 3 sind beim Ausführungsbeispiel zylindrisch ausgebildet. Es ist aber auch möglich, den Querschnitt des Schreibmittels 1 und den freien Querschnitt des Halteglieds 3 beispielsweise quadratisch auszubilden.Because the holding member 3 can be changed over its entire length in the free cross section, the holding member 3 can also be pushed without difficulty over writing means 1 which are larger in cross section than the desired cross section. The holding member 3 is made of plastic, in particular from the material known under the trademark Hostalen. The elongated writing medium 1 and the interior of the holding member 3 receiving the writing medium 1 are cylindrical in the exemplary embodiment. However, it is also possible to design the cross section of the writing means 1 and the free cross section of the holding member 3 to be square, for example.
