Description

Die Erfindung betrifft ein Schreibgerät, insbesondere einen Lackmarker.The invention relates to a writing instrument, in particular a paint marker.

Lacke, die mit solchen Schreib- bzw. Markierungsgeräten aufgetragen werden sollen, haben die Eigenschaft, dass sich in den Lacken enthaltene Farbpigmente nach einiger Zeit absetzen. Dieses Absetzen lässt sich insbesondere dann prinzipiell nicht verhindern, wenn das spezifische Gewicht der Farbpigmente größer ist als das des Lösungsmittels, in dem die Farbpigmente enthalten sind. Des weiteren muss der Lack dünnflüssig sein, damit er mit Hilfe üblicher Faserdochte, die als Lackleiter oder Auftragselemente dienen, aufgetragen werden kann. In einer Vorratskammer, in der ein Vorrat an Lack bzw. Tinte aufgenommen ist, befinden sich deshalb Kugeln, mit deren Hilfe der Lack aufgeschüttelt werden kann, so dass das Absetzen der Farbpigmente rückgängig gemacht werden kann.Paints to be applied with such writing or marking devices have the property that color pigments contained in the paints settle after some time. This settling can not be prevented in principle in particular if the specific gravity of the color pigments is greater than that of the solvent in which the color pigments are contained. Furthermore, the paint must be low viscosity so that it can be applied using conventional fiber wicks that serve as paint conductors or applicator elements. In a pantry, in which a supply of paint or ink is added, therefore, there are bullets, with the aid of which the paint can be shaken so that the discontinuation of the color pigments can be reversed.

Bekannt sind mit Ventilen arbeitende Lackmarker, bei denen ein Ventil durch Drücken auf eine Auftragsspitze geöffnet wird, wodurch der Lack aus der Vorratskammer in einen Kapillarspeicher aus Schaumstoffmaterial bzw. Kapillarmaterial strömt, aus welchem Kapillarspeicher anschließend geschrieben wird.Paint markers operating with valves are known, in which a valve is opened by pressing on an applicator tip, whereby the lacquer flows from the storage chamber into a capillary accumulator made of foam material or capillary material, from which capillary accumulator is subsequently written.

Eine Eigenart solcher bekannter Lackmarker liegt darin, dass beim Schreiben der Tintenfluss ausmagert, wenn die Tinte im Kapillarspeicher langsam zu Ende geht. Durch Drücken auf die Auftragsspitze muss daher ständig für Nachschub gesorgt werden, was die Benutzung beeinträchtigt. Durch zu häufiges Drücken auf das Auftragselement kann der Kapillarspeicher überfüllt werden, wodurch der Marker kleckst. Die Farbpigmente setzen sich im Kapillarspeicher ab, so dass sich der Kapillarspeicher im Laufe der Zeit mit Pigmenten zusetzt.A peculiarity of such well-known paint markers is that when writing the ink flow emaciated when the ink in the capillary slowly comes to an end. By pressing on the applicator tip must therefore be constantly provided for replenishment, which affects the use. Excessive pressure on the applicator may overfill the capillary reservoir, causing the marker to spill. The color pigments settle in the capillary reservoir, so that the capillary accumulator becomes contaminated with pigments over time.

Im Oberbegriff des Anspruchs 1 wird von einem Schreibgerät gemäß der DE 38 22 456 A1 ausgegangen. Bei diesem Schreibgerät wird beim Bewegen einer Schiebehülse zusammen mit einem an ihr befestigten Dosierkolben aus einer Ruhestellung in eine Schreibstellung das Volumen einer zwischen der Schiebehülse und einem Gehäuse ausgebildeten Ring- bzw. Pumpkammer vergrößert, wobei axiale Nuten freigegeben werden, durch die hindurch Flüssigkeit in die Ringkammer und in von dieser ausgehende, durch die Schiebehülse hindurchführende Querkanäle gelangt. Beim anschließenden Bewegen der Schiebehülse in die Ruhestellung wird das Volumen der Ringkammer vom Dosierkolben verringert und Flüssigkeit aus der Ringkammer durch die Querkanäle in einen Tintenleiter umgebenden nach unten offenen ringförmigen Speicherraum gedrängt, der sich nach mehrmaligem Hin- und Herbewegen der Schiebehülse aus der Ruhestellung in Schreibstellung und umgekehrt mehr oder weniger mit Flüssigkeit füllt, die bei in Schreibstellung befindlicher Schiebehülse verschrieben werden kann.In the preamble of claim 1 is of a writing instrument according to the DE 38 22 456 A1 went out. In this writing instrument, the volume of a formed between the sliding sleeve and a housing annular or pumping chamber is increased when moving a sliding sleeve together with a dosing piston attached to it from a rest position to a writing position, wherein axial grooves are released, through which liquid in the Ring chamber and outgoing from this, passing through the sliding sleeve transverse channels. During subsequent movement of the sliding sleeve in the rest position, the volume reduced annular chamber from the metering and liquid from the annular chamber through the transverse channels in an ink guide surrounding downwardly open annular storage space urged that fills after repeated reciprocation of the sliding sleeve from the rest position in writing position and vice versa more or less with liquid at can be prescribed in writing position sliding sleeve.

Eine Eigenart des bekannten Schreibgerätes liegt darin, dass vor dem Schreiben mehrfach gepumpt werden muss, was einerseits unkomfortabel ist und andererseits Sorgfalt erfordert, damit kein Überfüllen der Ringkammer erfolgt. Außerdem besteht durch die nach unten offene Ringkammer Klecksgefahr.A peculiarity of the known writing instrument is that must be pumped several times before writing, which on the one hand is uncomfortable and on the other hand requires care, so that no overfilling of the annular chamber. In addition, there is a risk of splashing through the downwardly open annular chamber.

In der DE 203 09 027 U1 ist ein Schreibgerät mit einem Behälter für freie Flüssigkeit beschrieben, das ein durch einen Kapillarspeicher hindurchführendes kapillares Auftragselement und eine von dem Auftragselement betätigte Ventilanordnung enthält. Ohne Ausübung einer Druckkraft auf das Auftragselement bleibt ein das Auftragselement mit einer Zwischenkammer verbindendes erstes Ventil geschlossen, während ein die Zwischenkammer mit dem Flüssigkeitsvorrat verbindendes zweites Ventil geöffnet ist. Bei mäßiger Druckausübung auf das Auftragselement wird das erste Ventil geöffnet. Bei großem Druck wird das zweite Ventil geschlossen.In the DE 203 09 027 U1 a writing instrument is described with a container for free liquid, which contains a capillary through a capillary storage capillary applicator element and operated by the applicator valve assembly. Without exerting a compressive force on the applicator element, a first valve connecting the applicator element with an intermediate chamber remains closed while a second valve connecting the intermediate chamber with the fluid reservoir is opened. If the application element is subjected to moderate pressure, the first valve is opened. At high pressure, the second valve is closed.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Schreibgerät derart weiterzuentwickeln, dass komfortabel und ohne Klecksgefahr auch pigmenthaltige Tinte verschrieben werden kann.The invention has for its object to further develop a generic writing instrument such that comfortable and without danger of inking pigment ink can be prescribed.

Preferably, the actuating member 24 is slidable with its end portion 30 relative to the ink guide 18, wherein air can flow into the interior of the actuating part 24 by an axial ribbing.

Die bewegliche Wand 26 ist längs ihres Außenumfangs vorzugsweise mit einem Dichtring 31 versehen, so dass sie in der in Fig. 1 dargestellten Stellung dichtend an der Innenwand des Gehäuses 10 anliegt. In ähnlicher Weise ist der innere Rand der Stirnwand 14 vorzugsweise mit einem Dichtring 32_versehen, so dass der Innenrand der Stirnwand 14 dichtend an der Außenseite des Ansatzes 22 geführt ist.The movable wall 26 is preferably provided along its outer periphery with a sealing ring 31, so that they in the in Fig. 1 shown position sealingly on the inner wall of the housing 10 is present. Similarly, the inner edge of the end wall 14 is preferably provided with a sealing ring 32_, so that the inner edge of the end wall 14 is sealingly guided on the outside of the neck 22.

Die Außenseite des Ansatzes 22, die Innenseite des zylindrischen Endbereichs 12, die Stirnwand 14 und die bewegliche Wand 26 begrenzen eine Speicherkammer 34, die im dargestellten Zustand von einer im Gehäuse 10 ausgebildeten Vorratskammer 36, in der ein Vorrat an Tinte bzw. Lackflüssigkeit aufgenommen ist, abgetrennt ist.The outer side of the projection 22, the inside of the cylindrical end portion 12, the end wall 14 and the movable wall 26 define a storage chamber 34, which in the illustrated state of a formed in the housing 10 storage chamber 36 in which a supply of ink or paint liquid is added , is separated.

In der Speicherkammer 34 ist ein Kapillarspeicher 38 aufgenommen, der aus elastisch zusammendrückbarem, kapillarem Material besteht.In the storage chamber 34, a capillary 38 is received, which consists of elastically compressible, capillary material.

Auf der Innenseite der Wandung des zylindrischen Endbereiches 12 sind in Fig. 1 unmittelbar unterhalb des Dichtrings 31 axiale Überströmnuten 40 ausgebildet.On the inside of the wall of the cylindrical end portion 12 are in Fig. 1 31 axial Überströmnuten 40 formed immediately below the sealing ring.

In dem Zylinder Ansatz 22 ist in der in Fig. 1 dargestellten Stellung unmittelbar oberhalb des Dichtrings 32 wenigstens ein radialer Schreibdurchlass 42 und in axialem Abstand davon wenigstens ein radialer Luftdurchlass 44 ausgebildet.In the cylinder approach 22 is in the in Fig. 1 illustrated position immediately above the sealing ring 32 at least one radial writing passage 42 and at an axial distance thereof at least one radial air passage 44 is formed.

In der Vorratskammer 36 können Kügelchen 46 angeordnet sein, mit denen in der Vorratskammer 36 befindliche Tinte aufgeschüttelt werden kann.In the storage chamber 36 beads 46 may be arranged with which in the storage chamber 36 located ink can be shaken.

Der vorzugsweise in dem Ansatz 16 des Gehäuses 10 festgehaltene Tintenleiter 18 ragt in den Zylinder 22 derart ein, dass er sich im Bereich des Schreibdurchlasses 42 in unmittelbarer Anlage an der Innenwand des Zylinders 22 und damit in direktem Kontakt mit dem Schreibdurchlass 42 befindet. Der Tintenleiter 18 ist im Zylinder 22 vorzugsweise derart beweglich geführt, dass zwischen ihm und der Innenwand des Ansatzes 22 ein Luftpfad 48 gebildet ist, so dass die Speicherkammer 34 durch den Luftdurchlass 44, den Luftpfad 48 und weitere Durchströmdurchlässe mit der Umgebung verbunden ist.The ink guide 18, which is preferably held in the projection 16 of the housing 10, protrudes into the cylinder 22 in such a way that it is in direct contact with the inner wall of the cylinder 22 and thus in direct contact with the writing passage 42 in the region of the writing passage 42. The ink guide 18 is preferably movably guided in the cylinder 22 such that an air path 48 is formed between it and the inner wall of the projection 22, so that the storage chamber 34 is connected to the environment through the air passage 44, the air path 48 and further Durchströmdurchlässe.

Die beschriebenen Bauteile bestehen aus verschiedenen Elementen, so dass das Gerät durch Zusammensetzen der Elemente zu der dargestellten Form zusammenbaubar ist.The described components consist of different elements, so that the device can be assembled by assembling the elements into the illustrated shape.

Die Funktion des beschriebenen Geräts ist folgende:The function of the described device is as follows:

In der dargestellten Stellung befindet sich das Betätigungsbauteil 24 in seiner Betätigungsstellung, in der das Volumen der Speicherkammer 34 und des darin aufgenommenen Kapillarspeichers 38 maximal ist, wobei der Kapillarspeicher 38 zunächst mit Tinte gefüllt ist, die durch den Schreibdurchlass 42 hindurch in den Tintenleiter 18 gelangt, von dem aus sie mit dem Auftragselement 20 verschrieben bzw. zur Markierung einer Unterlage genutzt werden kann. Das Volumen von aus der Vorratskammer 36 verbrauchter Tinte wird durch Luft ersetzt, die durch den Luftpfad 48 und den Luftdurchlass 44 in die Speicherkammer 34 einströmt.In the illustrated position, the actuating member 24 is in its operating position in which the volume of the storage chamber 34 and the capillary 38 received therein is maximum, wherein the capillary 38 is first filled with ink, which passes through the write passage 42 into the ink conductor 18 from which it can be prescribed with the applicator 20 or used to mark a pad. The volume of ink consumed from the storage chamber 36 is replaced by air flowing through the air path 48 and the air passage 44 into the storage chamber 34.

Sei nun angenommen, ein Markierungs- bzw. Schreibvorgang ist beendet und in dem Kapillarspeicher 38 befindet sich noch Tinte. Nach Beendigung des Markierungsvorgangs wird das Betätigungselement 24 gemäß Fig. 1 nach unten in eine untere Endstellung verschoben, in der das Auftragselement 20 innerhalb des Endteils 30 geschützt aufgenommen ist und das Volumen der Speicherkammer 34 sowie des Kapillarspeichers 38 durch abwärts Bewegen der beweglichen Wand 26 minimal ist. Beim Bewegen des Betätigungsbauteils 24 aus der dargestellten Betätigungsstellung in die Endstellung bewegt sich der Schreibdurchlass 42 durch den Dichtring 32 der Stirnwand 14 hindurch, so dass der Schreibdurchlass 42 von der Speicherkammer 34 getrennt wird. Des weiteren bewegt sich der Außenumfang der beweglichen Wand 26 in den Bereich der Überströmnuten 40, so dass infolge der Kompression des Kapillarspeichers 38 aus diesen herausgedrückte Tinte in die Vorratskammer 36 zurückströmt. Vorteilhaft ist, wenn die axiale Länge der Überströmnuten 40 derart auf den möglichen Hub des Betätigungsbauteils 24 abgestimmt ist, dass in der gemäß Fig. 1 untersten Ruhestellung des Betätigungsbauteils 24 der Dichtring 31 die Überströmnuten 40 vollständig überfahren hat und das Innere der Speicherkammer 34 wiederum gegen die Vorratskammer 36 abgedichtet ist.Suppose now that a marking or writing process has ended and there is still ink in the capillary memory 38. After completion of the marking operation, the actuator 24 is according to Fig. 1 shifted down to a lower end position in which the applicator member 20 is received protected within the end portion 30 and the volume of the storage chamber 34 and the capillary 38 by moving down the movable wall 26 is minimal. When moving the operating member 24 from the illustrated operating position to the end position, the writing passage 42 moves through the sealing ring 32 of the end wall 14, so that the writing passage 42 is separated from the storage chamber 34. Furthermore, the outer circumference of the movable wall 26 moves into the area of the overflow grooves 40, so that due to the compression of the capillary memory 38, ink pushed out of these flows back into the storage chamber 36. It is advantageous if the axial length of the Überströmnuten 40 is tuned to the possible stroke of the actuating member 24 such that in accordance with Fig. 1 lowest rest position of the actuating member 24 of the sealing ring 31 has the overflow grooves 40 completely run over and the interior of the storage chamber 34 is in turn sealed against the storage chamber 36.

Zusätzlich kann bei längerem Nichtgebrauch auf den Endteil 30 eine Kappe aufgesetzt werden, so dass ein luftdichter Abschluss besteht und in dem Auftragselement 20 verbliebene Tinte nicht eintrocknen kann.In addition, when not in use for a long time, a cap may be put on the end part 30 so that there is an airtight seal and ink left in the applicator element 20 can not dry.

Wenn das Schreibgerät für die Markierung wieder in Betrieb genommen werden soll, wird das Betätigungsbauteil 24 aus der Ruhestellung in die dargestellte Stellung zurückbewegt, wobei während dieser Bewegung die Überstromnuten 40 wiederum freigegeben werden, so dass sich die in ihrem Volumen vergrößernde Speicherkammer 34 bzw. der darin befindliche Kapillarspeicher 38 wiederum mit Tinte füllt, die anschließend für eine erneute Markierung zur Verfügung steht.When the writing instrument for marking is to be put back into operation, the actuating member 24 is moved back from the rest position to the position shown, during which the Überstromnuten 40 are released again, so that the volume-increasing in their storage chamber 34 and the Capillary storage located therein 38 again with ink, which is then available for re-marking.

Insgesamt bildet der Dichtring 31 zusammen mit den Überstromnuten 40 ein erstes Ventil. Ein zweites Ventil ist durch den Dichtring 32 und dessen Zusammenwirken mit dem Schreibdurchlass 42 gebildet.Overall, the sealing ring 31 forms together with the Überstromnuten 40, a first valve. A second valve is formed by the sealing ring 32 and its interaction with the writing passage 42.

Es versteht sich, dass das beschriebene Gerät in vielfältiger Weise abgeändert werden kann. Beispielsweise müssen die Abdichtungen nicht durch gesonderte Dichtringe, Lippendichtungen oder sonstiges gebildet sein, sondern können unmittelbar einteilig mit den Umfangsrändern der entsprechenden Bauteile ausgebildet sein. Des weiteren können zwischen dem kappenartigen Betätigungsbauteil 24 und dem Gehäuse 10 Rasteinrichtungen vorgesehen sein, die in der Betätigungsstellung bzw. der Ruhestellung des Betätigungsbauteils 24 lösbar einrasten. Zusätzliche Federn können das Gerät in die dargestellte Betriebsstellung vorspannen. Dabei kann als Feder der Kapillarspeicher 38 selbst dienen.It is understood that the described device can be modified in many ways. For example, the seals need not be formed by separate sealing rings, lip seals or otherwise, but may be formed directly integrally with the peripheral edges of the respective components. Furthermore, locking devices can be provided between the cap-like actuating component 24 and the housing 10, which engage releasably in the actuating position or the rest position of the actuating component 24. Additional springs may bias the device into the illustrated operating position. It can serve as a spring, the capillary 38 itself.

Fig. 2 zeigt eine abgeänderte Ausführungsform eines Schreibgerätes. Dabei sind denen der Fig. 1 entsprechende Bauteile mit gleichen Bezugszeichen belegt, so dass nur die Unterschiede erläutert werden: Fig. 2 shows a modified embodiment of a writing instrument. Here are those of Fig. 1 corresponding components with the same reference numerals, so that only the differences are explained:

Bei dem Gerät gemäß Fig. 2 ist das Gehäuse 10 mit einer Zwischenwand 60 ausgebildet, die eine zentrale Öffnung aufweist, von der ein mit einem Sackkanal 62 versehender Vorsprung 64 ausgeht, der eine ringförmige Stirnwand 14 trägt, die wiederum mit einem dem Ansatz 16 der Fig. 1 ähnlichen Ansatz 16 ausgebildet ist, der den Tintenleiter 18 bzw. das Auftragselement 20 trägt. Von der zylindrischen Außenwand 28 des Betätigungsbauteils 24, in dem die Stirnwand 14 unter Abdichtung geführt ist, geht in dessen oberem Bereich radial nach innen eine mit einer zentralen Öffnung ausgebildete Querwand aus, die die bewegliche Wand 26 bildet, welche innen in einem Zylinder 22 endet, in dem der Vorsprung 64 des Gehäuses 10 verschiebbar aufgenommen ist. Der Zylinder 22 ist am Innenrand der Stirnwand 14 unter Abdichtung geführt.In the device according to Fig. 2 the housing 10 is formed with an intermediate wall 60 having a central opening, from which a projection 64 provided with a blind channel 62 emanates, which carries an annular end wall 14, which in turn engages with the shoulder 16 of FIG Fig. 1 similar approach 16 is formed, which carries the ink conductor 18 and the applicator element 20. Of the cylindrical outer wall 28 of the actuating member 24, in which the end wall 14 is guided under sealing, is in the upper region radially inwardly formed with a central opening transverse wall, which forms the movable wall 26, which ends inside in a cylinder 22 in which the projection 64 of the housing 10 is slidably received. The cylinder 22 is guided on the inner edge of the end wall 14 under sealing.

Wie aus Fig. 2 unmittelbar ersichtlich, ist zwischen der Zwischenwand 60 und der Stirnwand 14 des Gehäuses 10 ein Ringraum gebildet, innerhalb dessen die von dem Zylinder 22 der Außenwand 28, der Stirnwand 14 und der beweglichen Wand 26 gebildete Speicherkammer 34 ausgebildet ist, in der der Kapillarspeicher 38 angeordnet ist.How out Fig. 2 directly visible, an annular space is formed between the intermediate wall 60 and the end wall 14 of the housing 10, within which the storage chamber formed by the cylinder 22 of the outer wall 28, the end wall 14 and the movable wall 26 is formed, in which the capillary 38 is arranged is.

In dem Zylinder 22 sind in axialem Abstand wenigstens ein Schreibdurchlass 42, ein Luftdurchlass 44 und ein Tintendurchlass 66 ausgebildet. Von dem Sackkanal 62 führt ein radialer Durchlass 68 in eine Ringkammer, die durch zwei dichtend in dem Zylinder 22 geführte Ringflansche 70 und 72 des Vorsprungs 64 begrenzt ist.In the cylinder 22 at least one write passage 42, an air passage 44 and an ink passage 66 are formed at an axial distance. From the blind channel 62, a radial passage 68 leads into an annular chamber which is delimited by two annular flanges 70 and 72 of the projection 64 which are guided sealingly in the cylinder 22.

Die Funktion des Gerätes gemäß Fig. 2 ist folgende:The function of the device according to Fig. 2 is the following:

Die dargestellte Stellung ist die Betriebsstellung des Betätigungsbauteils 24, in der das Volumen der Speicherkammer 34 bzw. des Kapillarspeichers 38 maximal ist und der am Ansatz 16 des Gehäuses 10 gehaltene Tintenleiter 18, der in dem Zylinder 22 einragt, durch den Schreibdurchlass 42 hindurch in kapillarer Verbindung mit dem Kapillarspeicher 38 steht. Wenn das Betätigungsbauteil 24 aus der dargestellten Betätigungsstellung nach unten in seine Ruhestellung verschoben wird, überfährt der Schreibdurchlass 42 die Stirnwand 14, so dass der Schreibdurchlass 42 von der Speicherkammer 34 getrennt ist. Weiter überfährt der Ringflansch 70 den Tintendurchlass 66, so dass die Speicherkammer 34 durch den Tintendurchlass 66, die zwischen den Ringflanschen 70 und 72 gebildete Ringkammer und dem Durchlass 68 hindurch mit dem Sackkanal 62 und damit der Vorratskammer 36 verbunden ist.The position shown is the operating position of the actuating member 24, in which the volume of the storage chamber 34 and the capillary 38 is maximum and held at the base 16 of the housing 10 ink guide 18, which protrudes in the cylinder 22, through the write passage 42 into capillary Connection with the capillary 38 is. When the operating member 24 is shifted from the illustrated operating position down to its rest position, the write passage 42 passes over the end wall 14, so that the writing passage 42 is separated from the storage chamber 34. Next, the annular flange 70 passes over the ink passage 66, so that the storage chamber 34 through the ink passage 66, the annular chamber formed between the annular flanges 70 and 72 and the passage 68 through the bag channel 62 and thus the storage chamber 36 is connected.

Eine weitere Ausführungsform des Gerätes ist in Fig. 3 dargestellt.Another embodiment of the device is in Fig. 3 shown.

Bei der Ausführungsform gemäß Fig. 3 weist das Gehäuse 10 einen zylindrischen Endbereich 12 auf, wobei im Abstand von dessen Stirnende eine radial gerichtete Zwischenwand 60 ausgebildet ist, die eine zentrale Öffnung aufweist, von der ein Zylinder 22 vorsteht.In the embodiment according to Fig. 3 the housing 10 has a cylindrical end portion 12, wherein at the distance from the front end of a radially directed partition wall 60 is formed, which has a central opening from which a cylinder 22 protrudes.

In dem Zylinder 22 sind in axialem Abstand jeweils wenigstens ein radialer Schreibdurchlass 42, ein Luftdurchlass 44 und ein Tintendurchlass 66 ausgebildet. Zwischen dem Zylinder 22 und der Innenseite des zylindrischen Endbereichs 12 des Gehäuses 10 ist eine eine bewegliche Wand 26 bildende Ringwand des Betätigungsbauteils 24 unter Abdichtung geführt, wobei gemäß Fig. 3 der Tintenleiter 18 mit dem Auftragselement 20 an dem Endteil 30 des trichterförmig auslaufenden Betätigungsbauteils 24 gehalten ist. Das Betätigungsbauteil 24 ist an dem Endbereich 12 des Gehäuses 10 verschiebbar geführt. Durch den Tintenleiter 18 ragt ähnlich wie bei der Ausführungsform gemäß Fig. 2 ein Stößel, der bei der Ausführungsform gemäß Fig. 3 jedoch starr mit dem Betätigungsbauteil 24 verbunden ist und der in einem Kolben bzw. Schieber 74 endet, der in axialem Abstand voneinander mit Ringflanschen 76 und 78 ausgebildet ist, die an der Innenseite des Zylinders 22 dichtend geführt sind. Dazu können die Ringflansche 76 und 78 mit Dichtringen bestückt oder selbst als Dichtungen ausgebildet sein.At least one radial writing passage 42, an air passage 44 and an ink passage 66 are formed in the cylinder 22 at an axial distance. Between the cylinder 22 and the inside of the cylindrical end portion 12 of the housing 10, a movable wall 26 forming an annular wall of the actuating member 24 is guided under sealing, according to Fig. 3 the ink conductor 18 is held with the applicator 20 at the end portion 30 of the funnel-shaped expiring actuating member 24. The operating member 24 is slidably guided on the end portion 12 of the housing 10. By the ink conductor 18 protrudes similar to the embodiment according to FIG Fig. 2 a plunger, which in the embodiment according to Fig. 3 However, it is rigidly connected to the actuating member 24 and terminates in a piston or slide 74, the in axial distance from each other with annular flanges 76 and 78 is formed, which are sealingly guided on the inside of the cylinder 22. For this purpose, the annular flanges 76 and 78 can be equipped with sealing rings or even be designed as seals.

Die Funktion des Gerätes gemäß Fig. 3, das eine bevorzugte Ausführungsform die Erfindung ist, wird im folgenden anhand der Fig. 4 erläutert. Fig. 4 zeigt vier Diagramme, wobei auf der Abszisse jeweils die Stellung des Betätigungsbauteils 24 dargestellt ist. R bedeutet die Ruhestellung und S bedeutet die Schreibstellung. Die Ordinaten der oberen drei Diagramme geben den Zustand des Schreibdurchlasses 42, des Tintendurchlasses 66 und des Luftdurchlasses 44 an. Das unterste Diagramm gibt den Füllzustand bzw. die Tintenmenge TM an, die sich in der Speicherkammer 34 bzw. dem Kapillarspeicher 38 befindet.The function of the device according to Fig. 3 which is a preferred embodiment of the invention will be described below with reference to Fig. 4 explained. Fig. 4 shows four diagrams, wherein in each case the position of the actuating member 24 is shown on the abscissa. R means the rest position and S means the writing position. The ordinates of the upper three diagrams indicate the state of the write passage 42, the ink passage 66, and the air passage 44. The bottom diagram indicates the filling state or the ink quantity T M , which is located in the storage chamber 34 or the capillary storage 38.

Es sei angenommen, das Betätigungsbauteil 24 befindet sich in Schreibstellung, wie in Fig. 3 dargestellt. Der Schreibdurchlass 42 ist dann offen. Bei Bewegen des Betätigungsbauteils aus der Schreibstellung in Richtung der Ruhestellung gemäß Fig. 3 nach oben wird, wenn die Stellung a erreicht ist, der Schreibdurchlass 42 von der Speicherkammer 34 getrennt. Der Luftdurchlass 44 bleibt offen und wird bei Erreichen der Stellung b von der Speicherkammer 34 getrennt, wenn er von der beweglichen Wand 26 überfahren wird. Anschließend gelangt, wenn die Stellung c erreicht ist, der Ringflansch 76 aufwärts aus dem Zylinder 22 heraus, so dass eine Verbindung der Speicherkammer 34 mit der Vorratskammer 36 durch den Tintendurchlass 66 hindurch hergestellt wird und ab der Stellung c, für den Fall, dass zwischenzeitlich keine Tinte verschrieben wurde, in der Speicherkammer 34 befindliche Tinte in die Vorratskammer 36 zurückgedrückt wird, bis das Volumen der Speicherkammer 34 minimal ist, wenn das Betätigungsbauteil 24 seine Ruhestellung erreicht.It is assumed that the operating member 24 is in the writing position as in FIG Fig. 3 shown. The write port 42 is then open. When moving the operating member from the writing position in the direction of the rest position according to Fig. 3 upward, when the position a is reached, the writing port 42 is separated from the storage chamber 34. The air passage 44 remains open and is separated on reaching the position b of the storage chamber 34 when it is run over by the movable wall 26. Subsequently, when the position c is reached, the annular flange 76 comes up out of the cylinder 22, so that a connection of the storage chamber 34 is made with the storage chamber 36 through the ink passage 66 and from the position c, in the meantime no ink has been prescribed, in the storage chamber 34 ink is pushed back into the storage chamber 36 until the volume of the storage chamber 34 is minimal, when the operating member 24 reaches its rest position.

Beim Bewegen des Betätigungsbauteils 24 aus der Ruhestellung in die Schreibstellung laufen die Vorgänge in umgekehrter Reihenfolge ab.When moving the operating member 24 from the rest position to the writing position, the operations take place in the reverse order.

Wie ersichtlich, füllt sich die Speicherkammer 34 bzw. der Kapillarspeicher 38 beim Bewegen des Betätigungsbauteils 24 aus der Ruhestellung in die Schreibstellung nur mit Flüssigkeit, bis die Stellung c erreicht ist. Bei der weiteren Ausdehnung der Speicherkammer 34 gelangt Umgebungsluft in die Kammer bzw. in den Kapillarspeicher. Diese Luft wird, falls nicht geschrieben wird, bei der Rückwärtsbewegung des Betätigungsbauteils aus der Schreibstellung in die Ruhestellung durch den Luftdurchlass 44 herausgedrückt, ohne dass Flüssigkeit durch den Luftdurchlass 44 herausgedrängt wird. Wenn geschrieben wird, wird das verschriebene Flüssigkeitsvolumen in der Speicherkammer durch Luft ersetzt.As can be seen, the storage chamber 34 or the capillary 38 fills when moving the operating member 24 from the rest position to the writing position only with liquid until the position c is reached. In the further expansion of the storage chamber 34 ambient air enters the chamber or in the capillary storage. This air is, if not written, pushed in the backward movement of the actuating member from the writing position to the rest position through the air passage 44, without liquid through the air passage 44 is forced out. When writing, the prescribed volume of liquid in the storage chamber is replaced by air.

Wie sich aus dem Vorstehenden weiter ergibt, können der Luftdurchlass 44 und der Schreibdurchlass 42 zu einem gemeinsamen Durchlass zusammengefasst werden, wobei dann beispielsweise Kapillaren mit kleinster Kapillarität des Tintenleiters 18 als Luftdurchlasskapillaren fungieren.As will be apparent from the foregoing, the air passage 44 and the writing passage 42 may be combined to form a common passage, and then, for example, capillaries having the smallest capillarity of the ink guide 18 function as air passage capillaries.

Für einen Druckausgleich in der Vorratskammer 36 kann es vorteilhaft sein, in der Vorratskammer ein volumenveränderliches Element unterzubringen, beispielsweise einen Balg, dessen Inneres mit der Atmosphäre über eine Verbindungsöffnung verbunden ist, oder ein sonst wie geartetes elastisches Element.For a pressure balance in the storage chamber 36, it may be advantageous to accommodate a variable volume element in the storage chamber, for example a bellows, the interior of which is connected to the atmosphere via a connection opening, or an otherwise elastic element.

Anhand der Figuren 5 und 6 werden im folgenden zwei Modifizierungen der Ausführungsform des Gerätes gemäß Fig. 3 erläutert, die dessen Handhabung vereinfachen.Based on Figures 5 and 6 In the following two modifications of the embodiment of the device according to Fig. 3 explained, which simplify its handling.

Gemäß Fig. 5 geht der zylindrische Endbereich 12 des Gehäuses 10 in einen sich konisch verengenden Bereich 80 über, der in einem zylindrischen Endbereich 82 endet. Der zylindrische Endbereich 82 umgibt das gemäß Fig. 3 verlängerte zylindrische Endteil 30, das ähnlich wie in Fig. 3 starr mit der beweglichen Wand 26 verbunden ist und zusammen mit ihr das gegenüber der Fig. 3 verkleinert bzw. vereinfacht ausgeführte Betätigungsbauteil 24 bildet.According to Fig. 5 For example, the cylindrical end portion 12 of the housing 10 merges into a conically tapered region 80 terminating in a cylindrical end portion 82. The cylindrical end portion 82 surrounds the according to Fig. 3 elongated cylindrical end portion 30, which is similar to in Fig. 3 is rigidly connected to the movable wall 26 and together with her that against the Fig. 3 reduced or simplified running actuator component 24 forms.

Zwischen dem Betätigungsbauteil 24 bzw. der der beweglichen Wand zugewandten Stirnseite des Endteils 30 und einem Ringansatz 84 des gehäusefesten Zylinders 22 ist eine Feder 86 angeordnet, die das Betätigungsbauteil 24 in Schreibstellung vorspannt, in der der Tintenleiter 18 über den Schreibdurchlass 42 mit der Speicherkammer 34 verbunden ist.Between the actuating member 24 and the movable wall facing end side of the end portion 30 and a ring shoulder 84 of the housing fixed to the cylinder 22, a spring 86 is arranged, which biases the actuating member 24 in the writing position, in which the ink conductor 18 via the write passage 42 with the storage chamber 34th connected is.

Um das Betätigungsbauteil 24 in seine Ruhestellung zu bewegen bzw. das Gerät außer Betrieb zu setzen, ist eine Kappe 88 vorgesehen, die mit einem inneren Ringansatz 90 den Tintenieiter 18 umgibt und an dem freien Stirnende des Endteils 30 anliegt. Der Innendurchmesser der Kappe 88 ist derart, dass sie auf den zylindrischen Endbereich 12 des Gehäuses 10 unter Passung aufschiebbar ist. Beim Aufschieben der Kappe 88 auf das Gehäuse 10 wird das Betätigungsbauteil 24 bzw. dessen beweglichen Wand 26 gemäß Fig. 5 nach oben in die Ruhestellung verschoben, wobei das Gerät funktioniert wie anhand Fig. 3 beschrieben. Die Kappe kann am Gehäuse 10 durch Reibung gehalten werden oder es können an sich bekannte Rasteinrichtungen oder auch ein Gewinde vorgesehen sein, so dass die Kappe in der der Ruhestellung des Betätigungsbauteils 24 entsprechenden Stellung sicher gehalten ist. Bei der Ausführung gemäß Fig. 5 bildet das Betätigungsbauteil 24 kein manuell betätigbares Teil, sondern ein Ventilglied, das die Wirksamkeit der Durchlässe 42, 44 und 66 in der beschriebenen Weise steuert.In order to move the actuating member 24 in its rest position or to put the device out of service, a cap 88 is provided which surrounds the Tintenieiter 18 with an inner annular projection 90 and rests against the free end face of the end portion 30. The inner diameter of the cap 88 is such that it is slidably fitted onto the cylindrical end portion 12 of the housing 10. When the cap 88 is pushed onto the housing 10, the actuating component 24 or its movable wall 26 is adjusted accordingly Fig. 5 moved upwards to the rest position, the device works as described Fig. 3 described. The cap can on the housing 10th be held by friction or it can be provided per se known locking devices or a thread, so that the cap is held securely in the position corresponding to the rest position of the operating member 24. In the execution according to Fig. 5 The operating member 24 does not constitute a manually operable member but a valve member which controls the effectiveness of the passages 42, 44 and 66 in the manner described.

Die Fig. 6 zeigt eine weitere abgeänderte Ausführungsform, bei der das Betätigungsbauteil 24 zusammen mit dem Schieber 74 und dem Tintenleiter 18 bzw. Docht vom hinteren Ende des Gehäuses 10 her betätigt werden kann. Dazu ist der Schieber 74 über ein stab- oder rohrförmiges Verbindungsteil 92 mit einer auf den Endbereich des Gehäuses 10 aufgesetzten Kappe 94 verbunden. Das Verbindungsteil 92 ist unter Abdichtung durch die Rückwand 96 des Gehäuses 10 durchgeführt. Zwischen der Rückwand 96 und der Kappe 94 ist vorteilhafterweise eine Feder 98 angeordnet, die das Betätigungsbauteil 24 in seine Ruhestellung vorspannt.The Fig. 6 shows a further modified embodiment in which the actuating member 24 can be actuated together with the slider 74 and the ink conductor 18 or wick from the rear end of the housing 10 ago. For this purpose, the slider 74 is connected via a rod-shaped or tubular connecting part 92 with a cap 94 placed on the end region of the housing 10. The connecting part 92 is performed under sealing by the rear wall 96 of the housing 10. Between the rear wall 96 and the cap 94, a spring 98 is advantageously arranged, which biases the actuating member 24 in its rest position.

Die Kappe 94 kann beispielsweise mit einem inneren Ansatz 100 in eine an der Außenseite des Gehäuses 10 ausgebildete, zur axialen Richtung in einem Winkel verlaufende Umfangsnut 102 eingreifen, so dass sich bei einer Verdrehung der Kappe 94 relativ zum Gehäuse 10 das Betätigungsbauteil 24 axial zwischen der Ruhestellung und der Schreibstellung verschiebt. Die Kappe kann auch mit einem an sich bekannten Mechanismus ähnlich einem Druckkugelschreiber vorgesehen sein, so dass das Betätigungsbauteil 24 bei einem Druck auf die Kappe 94 die Schreibstellung und bei nochmaligem Druck die Ruhestellung annimmt.The cap 94 may, for example, engage with an inner projection 100 in a peripheral groove 102 formed at the outer side of the housing 10 so as to be angular relative to the axial direction, such that upon rotation of the cap 94 relative to the housing 10, the actuating member 24 is axially interposed Rest position and the writing position shifts. The cap can also be provided with a mechanism known per se similar to a ballpoint pen, so that the actuating member 24 assumes the position of writing upon pressing on the cap 94 and the rest position upon repeated pressure.

Wie in Fig. 6 weiter dargestellt, ist das Gehäuse 10 an seinem vorderen Ende verjüngt und sind am vorderen Innenrand des Gehäuses Segmentschalen 104 gelagert, die mittels Federn 106 derart vorgespannt sind, dass die Vorderränder 108 eine zwischen den Segmentschalen 104 bestehende Durchgangsöffnung, durch die in Schreibstellung des Betätigungsbauteils 24 der Tintenleiter 18 hindurchragt, schließt. Die gesamte Anordnung ist derart, dass sich der Tintenleiter 18 in Ruhestellung des Betätigungsbauteils 24 so weit gemäß Fig. 6 nach oben zurückzieht, dass die Vorderränder 108 schließen, so dass der Tintenleiter nicht austrocknen kann. Beim Bewegen des Betätigungsbauteils 24 in die Schreibstellung drückt das vordere Ende des Tintenleiters 18 die Vorderränder 108 auseinander und bewegt sich in die in Fig. 6 dargestellte Stellung.As in Fig. 6 shown further, the housing 10 is tapered at its front end and are mounted on the front inner edge of the housing segment cups 104, which are biased by means of springs 106 such that the front edges 108 existing between the segmental shells 104 through opening in the writing position of the actuating member 24th the ink conductor 18 protrudes, closes. The entire arrangement is such that the ink guide 18 in the rest position of the operating member 24 so far according to Fig. 6 retracting upward so that the leading edges 108 close so that the ink conductor can not dry out. As the actuating member 24 is moved to the writing position, the leading end of the ink guide 18 forces the leading edges 108 apart and moves into the in-plane position Fig. 6 shown position.

Die Merkmale der im Vorstehenden beispielhaft beschriebenen Schreibgeräte können in unterschiedlicher Weise miteinander kombiniert werden, solange nur der Grundgedanke der Erfindung realisiert wird, nämlich ein Schreibgerät zu schaffen, bei dem in Schreibstellung aus einer zumindest teilweise mit Schreibflüssigkeit gefüllten Speicherkammer heraus geschrieben wird und die Speicherkammer bei einem Umschalten des Schreibgerätes in eine Ruhestellung in die Vorratskammer zumindest größtenteils entleert wird. Typische Volumina der Speicherkammer 34 liegen beispielsweise zwischen 0,1 und 3 cm3. Typische Volumina der Vorratskammer 36 betragen beispielsweise zwischen 1 und 20 cm3. Der Kapillarspeicher kann beispielsweise aus Polyurethan oder einem anderen zusammendrückbaren Material geeigneter Kapillarität bzw. Kapillaritätsverteilung bestehen, wobei die Steighöhe eines großen Teils der Kapillaren über 3 cm liegt.The features of the writing utensils described above by way of example may be combined in different ways with each other, as long as only the basic idea of the invention is realized, namely to provide a writing instrument, is written in the writing position from an at least partially filled with writing fluid storage chamber and the storage chamber is emptied at a switching of the writing instrument in a rest position in the pantry, at least for the most part. Typical volumes of the storage chamber 34 are for example between 0.1 and 3 cm 3 . Typical volumes of the storage chamber 36 are for example between 1 and 20 cm 3 . For example, the capillary reservoir can be made of polyurethane or other compressible material of suitable capillarity or capillarity distribution, with the height of rise of a large part of the capillaries being over 3 cm.
