Description

Die Erfindung betrifft ein Schreibgerät, insbesondere Füllhalter, mit einem mit Tinte oder einer anderen Schreibflüssigkeit füllbaren Vorratsraum, der über einen durch ein in seiner Grundstellung offenes Trennventil sperrbaren Verbindungskanal mit einem Strömungsregler und einer Schreibspitze in Verbindung steht, wobei der Vorratsraum eine von außen zugängliche, durch ein selbsttätig schließendes Ventil verschlossene Nachfüllöffnung hat, an die ein mit Mitteln zum Offenhalten des Ventils versehener Nachfüllbehälter dicht anschließbar ist.The invention relates to a writing instrument, in particular fountain pens, with an ink or other writing fluid fillable storeroom, which is connected by a through a lockable in its basic position Connection channel with a flow regulator and one Writing tip communicates with the pantry one accessible from the outside by an automatic closing valve has a closed refill opening which is provided with means for keeping the valve open Refill container is tightly connectable.

Bei einem aus der US-A-2 938 499 bekannten Schreibgerät der angegebenen Art ist in dem Vorratsraum ein Schwimmer angeordnet, der beim Füllen des mit der Schreibspitze nach oben gehaltenen, an den Nachfüllbehälter angeschlossenen Schreibgeräts das Trennventil schließt, wenn der Vorratsraum gefüllt ist. Befindet sich das Schreibgerät in Schreibstellung mit der Schreibspitze nach unten, so öffnet der Schwimmer das Trennventil, so daß die Schreibflüssigkeit durch den Verbindungskanal zur Schreibspitze gelangen kann.In a writing device known from US-A-2 938 499 specified type, a float is arranged in the storage room, the one when filling the with the writing tip up held, connected to the refill container Writing instrument closes the isolation valve when the pantry is filled. The writing instrument is in Writing position with the writing tip down, so opens the float the isolation valve so that the writing fluid through the connecting channel to the writing tip can.

Der CH-A-255 993 ist ein Nachfüllbehälter als bekannt zu entnehmen, der mit Hilfe eines Füllrohrs an den Vorratsraum eines Füllhalters der eingangs genannten Art anschließbar ist, um diesen erneut mit Schreibflüssigkeit zu füllen. Das Füllrohr ist gegen die Kraft einer Feder axial beweglich vor der durch ein Ventilplättchen verschlossenen Behälteröffnung angebracht, von der ein Schlauch zum Behälterboden führt. Ein ebensolches Ventilplättchen befindet sich in der Nachfüllöffnung des Füllhalters. Mit Hilfe einer durch einen Gummiballon gebildeten Luftpumpe kann der Nachfüllbehälter unter Druck gesetzt werden. Zum Nachfüllen wird das Schreibgerät mit seiner Nachfüllöffnung auf das Füllrohr aufgesetzt und nach unten gegen den Nachfüllbehälter gedrückt, wobei das Füllrohr beide Ventilplättchen durchdringt und dadurch den Schlauch mit dem Vorratsraum des Füllhalters verbindet. Durch den im Nachfüllbehälter erzeugten Überdruck gegenüber dem äußeren Luftdruck wird die Flüssigkeit über den Schlauch und das Füllrohr in den Vorratsraum des Füllhalters gedrückt, wobei die in diesem befindliche Luft über den Belüftungskanal an der Spitze des Füllhalters entweicht. Nach dem Füllen wird der Füllhalter von dem Füllrohr abgezogen, wobei sich die Öffnungen in den Ventilplättchen wieder selbsttätig schließen.The CH-A-255 993 is a refill container known as remove it to the storage room with the help of a filling pipe a fountain pen of the type mentioned can be connected to refill it with writing fluid. The Filling tube is axially movable against the force of a spring in front of the container opening closed by a valve plate attached, from which a hose to the tank bottom leads. There is also a valve plate in the Refill opening of the fountain pen. With the help of a The refill container can be a rubber balloon formed air pump to be put under pressure. For refilling it will be Writing instrument with its refill opening on the filling tube put on and down against the refill container pressed, the filling tube penetrating both valve plates and thereby the hose with the storage space of the Fountain pen connects. Through the in the refill container generated overpressure against the outside air pressure the liquid through the hose and the filling pipe into the Storage space of the fountain pen pressed, the in this Air is at the top of the ventilation duct Fountain pen escapes. After filling, the fountain pen deducted from the fill tube, the openings in the Close the valve plate again automatically.

Aus der GB-A-6570 ist ein Füllhalter bekannt dessen Schaft einen Vorratsraum und einen Reserveraum enthält, die durch eine Wand, in der sich ein Nachfüllventil befindet, voneinander getrennt sind. Daneben ist ein Trennventil vorgesehen, durch das der von dem Vorratsraum zur Schreibspitze führende Verbindungskanal in dem Spitzenteil verschließbar ist. Die Verschlußelemente beider Ventile sind durch einen Stößel mit einem als Schraube ausgebildeten Drehknopf verbunden, der am hinteren Ende des Füllhalters angeordnet ist. Ist die Tinte in dem Vorratsraum verbraucht, so wird durch Drehen des Drehknopfs zunächst das Nachfüllventil geöffnet und danach, wenn das Nachfüllventil seine maximale Öffnungsstellung erreicht hat, das Trennventil geschlossen. Anschließend wird der Füllhalter mit der Schreibspitze nach unten gehalten und geschüttelt, um die Tinte aus dem Reserveraum in den Vorratsraum zu transportieren. Hierbei wird durch das geschlossene Trennventil das Heraustreten von Tinte an der Schreibspitze vermieden. Der Füllhalter wird durch Abschrauben seines Spitzenteils und damit auch der Sitzfläche des Trennventils von dem Schaft mit Tinte gefüllt. Das Trennventil ist beim Füllen somit offen.From GB-A-6570 a fountain pen is known whose shaft contains a pantry and a spare room that through a wall in which a refill valve is located from each other are separated. A separating valve is also provided, through that from the store to the writing tip leading connecting channel can be closed in the tip part is. The closure elements of both valves are by a plunger with a screw Knob connected to the rear end of the fountain pen is arranged. If the ink in the storage room is used up, So, by turning the rotary knob, that is first Refill valve open and then when the refill valve the isolating valve has reached its maximum opening position closed. Then the fountain pen with the Nib held down and shaken to the Transport ink from the reserve room to the store room. Here, the closed isolating valve Avoid ink leakage at the nib. The Fountain pen is made by unscrewing its tip part and thus also the seat of the separating valve from the stem filled with ink. The isolating valve is thus when filling open.

Aus der US-PS 2 646 777 ist ein nachfüllbares Schreibgerät bekannt, bei dem der Vorratsraum an dem der Schreibfeder entgegengesetzten Ende mit einer Kolbenpumpe versehen ist, die durch ein aus dem Vorratsraum herausragendes Saugrohr betätigbar ist. Zum Nachfüllen des Vorratsraums wird das Saugrohr in einen Tintenbehälter getaucht und durch Aufund Niederbewegen des Schreibgeräts die Kolbenpumpe betätigt. Hierbei ist von Nachteil, daß beim Nachfüllen durch den im Vorratsraum ansteigenden Druck im Tintenregler vorhandene Tinte an der Schreibspitze austritt, so daß die Außenseite des Schreibgeräts und die Finger der Bedienungsperson mit Tinte beschmutzt werden können. Ebenso kann es leicht zu einem Überfüllen des Vorratsraums und der Tintenkammern im Tintenregler kommen, wodurch das Schriftbild beim Schreiben anfänglich unsauber wird. Schließlich ist die Handhabung des bekannten Schreibgeräts umständlich und das aus dem Vorratsraum herausragende Saugrohr macht die Anordnung einer zusätzlichen Schutzhülse erforderlich.A refillable writing instrument is known from US Pat. No. 2,646,777 known, in which the storage room on the pen opposite end is provided with a piston pump, through a suction pipe protruding from the storage room can be actuated. To refill the storage room, this will be Suction tube dipped in an ink tank and opened and closed Moving down the writing instrument actuated the piston pump. The disadvantage here is that when refilling the increasing pressure in the ink regulator in the storage room Ink emerges from the writing tip, so that the Outside of the writing instrument and the operator's fingers can be stained with ink. It can also be easy to overfill the pantry and ink chambers come in the ink regulator, causing the typeface gets messy when writing. Finally is the handling of the known writing instrument cumbersome and the suction pipe protruding from the storage room does that Arrangement of an additional protective sleeve required.

Der Erfindung liegt die Aufgabe zugrunde, ein Schreibgerät der eingangs genannten Art derart zu gestalten, daß es wiederholt mit Tinte oder Schreibflüssigkeit gefüllt werden kann, ohne daß ein Überfüllen möglich ist und daß es beim Nachfüllen des Vorratsraums nicht zu einer übermäßigen Tintenzufuhr an der Auftragsspitze kommen kann.The invention has for its object a writing instrument the type mentioned in such a way that it repeats filled with ink or writing fluid can, without overfilling is possible and that it is Do not refill the reservoir to excessive ink supply can come at the top of the order.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Trennventil durch ein Betätigungselement mit einer Drucktaste verbunden ist und durch Eindrücken der Drucktaste in seine Schließstellung gelangt und daß beim Anschließen des Nachfüllbehälters an die Nachfüllöffnung die Drucktaste durch den Nachfüllbehälter eindrückbar und das Öffnen des selbsttätig schließenden Ventils erst in der Schließstellung des Trennventils möglich ist.This object is achieved in that the Isolation valve by an actuator with a push button is connected and by pressing the push button in reaches its closed position and that when connecting the Refill the push button at the refill opening pushable through the refill container and opening the automatically closing valve only in the closed position of the isolating valve is possible.

Bei dem erfindungsgemäßen Schreibgerät ist beim erneuten Füllen mit Tinte der Vorratsraum durch das Trennventil immer von der Schreibspitze und dem Strömungsregler getrennt. Das Schreibgerät kann daher bei erneutem Füllen nur soviel Tinte aufnehmen, wie der Vorratsraum fassen kann. Ein Überfüllen mit der Folge, daß Tinte an der Schreibspitze austritt ist nicht möglich. Ein gegenüber dem Atmosphärendruck erhöhter Druck im Vorratsraum, wozu es beim erneuten Füllen mit Tinte kommen kann, kann daher nicht zu einem Überangebot von Tinte an der Schreibspitze und dem Kapillarsystem des Strömungsreglers führen. Da der Vorratsraum auf einfache Weise wieder mit Tinte gefüllt werden kann, kann er in seiner Größe der Druckausgleichskapazität des Strömungsreglers optimal angepaßt werden.In the writing instrument according to the invention is the renewed Fill the storage space with ink through the isolation valve always from the writing tip and the flow regulator Cut. The writing instrument can therefore be filled again only take up as much ink as the storage room can hold can. An overfilling with the result that ink on the Pen tip is not possible. One versus that Atmospheric pressure increased pressure in the storage room, what for can come when refilling with ink not too much ink at the tip and the capillary system of the flow controller. Since the Stockroom easily refilled with ink can be in its size the pressure equalization capacity the flow controller can be optimally adjusted.

Die Betätigung des Trennventils kann auf einfache Weise dadurch erfolgen, daß das Verschlußelement des Trennventils an einem Stößel befestigt ist. Hierbei kann das Verschlußelement des Trennventils gegenüber dem Stößel axial bewegbar sein, damit Unterschiede zwischen dem Schließweg des Verschlußelements und dem Betätigungsweg des Stößels ausgeglichen werden.The actuation of the isolating valve can easily done by that the closure element of the isolation valve on one Plunger is attached. Here, the closure element of the Separating valve to be axially movable relative to the plunger, thus differences between the closing path of the closure element and the actuation path of the ram balanced become.

Eine bevorzugte Ausgestaltung der Erfindung sieht vor, daß das Trennventil ein, Verschlußelement aufweist, das von einem elastisch verformbaren Schlauch gebildet wird, der mit seinem freien Ende an einen Ventilsitz am Eintrittsende des Verbindungskanals andrückbar ist. Diese Ausgestaltung des Trennventils zeichnet sich vor allem durch einen geringen Herstell- und Montageaufwand und durch eine geringe Verschleißanfälligkeit aus.A preferred embodiment of the invention provides that the isolating valve has a closure element which is of an elastic deformable tube is formed the one with his free end to a valve seat at the inlet end of the connecting channel is pressable. This configuration of the Isolation valve is mainly characterized by a low Manufacturing and assembly costs and due to a low susceptibility to wear out.

Eine andere Ausgestaltung der Erfindung sieht vor, daß das Trennventil einen Ventilsitz mit einer durch eine zylindrische Bohrung gebildeten Sitzfläche aufweist, in die das Verschlußelement einsteckbar ist und die eine solche Länge hat, daß das Verschlußelement in seiner Schließstellung begrenzt axial bewegbar ist.Another embodiment of the invention provides that Isolation valve a valve seat with one by one Has cylindrical bore formed seat in the the closure element is insertable and such Length has that the closure element in its closed position is limited axially movable.

Der Tintenfluß durch das geöffnete Trennventil kann dadurch verbessert werden, daß an den Ventilsitz sich in Durchflußrichtung erstreckende Rippen angrenzen, die der Oberflächenspannung entgegenwirken und ein Haften einzelner Tropfen im Bereich der Durchtrittsöffnung des Ventils unterbinden.The ink flow through the open isolation valve can thereby improved be that at the valve seat itself in the flow direction extending ribs adjoin that of the surface tension counteract and stick individual drops in the area prevent the passage opening of the valve.

Die Drucktaste zur Betätigung des Trennventils verschließt vorzugsweise das der Schreibspitze entgegengesetzte Ende des Vorratsraums. Die Drucktaste kann an einer Druckfeder abgestützt sein, durch die sie in einer Grundstellung gehalten wird, in der das Trennventil geöffnet ist.The pushbutton for actuating the isolating valve closes preferably the end opposite the writing tip of the pantry. The push button can be on a compression spring be supported by being in a basic position is held in which the isolating valve is open.

Nach einem weiteren Vorschlag der Erfindung kann weiterhin die von außen zugängliche Nachfüllöffnung durch eine zentrale, an den Vorratsraum angeschlossenen Bohrung in der Drucktaste gebildet sein, die das selbsttägig schließende Ventil aufnimmt.According to a further proposal of the invention can continue the refill opening accessible from the outside through a central, hole connected to the storage room in the Push button formed, which is the self-closing Valve takes up.

Erfindungsgemäß kann weiterhin das selbsttätig schließende Ventil der Nachfüllöffnung aus einer Wand oder Membran aus elastomerem Werkstoff bestehen und eine vorgestochene, selbsttätig schließende Öffnung haben, durch die eine Hohlnadel eines Nachfüllbehälters von außen durchstechbar ist.

Zum Nachfüllen des Vorratsraums 2 ist in der Längsbohrung 22 der Drucktaste 20 eine wand 33 aus elastomerem Material angeordnet, die von außen durch eine enge Bohrung 34 zugänglich ist und eine vorgestochene, durch das Kontraktionsverhalten des Materials geschlossen gehaltene Öffnung 55 hat. Durch die Bohrung 34 kann die Öffnung 55 der Wand 33 mit einer Hohlnadel eines Nachfüllbehälters durchstochen und anschließend durch die Hohlnadel Tinte eingefüllt werden. Die beim Einfüllen neuer Tinte verdrängte Luft wird durch ständiges Wechseln des Drucks im Nachfüllbehälter intermittierend über die Hohlnadel abgesaugt. Die Wand 33 dichtet beim Nachfüllen die Hohlnadel ab und verhält sich wie ein selbsttätig schließendes Ventil. Sie zieht sich nach dem Herausziehen der Hohlnadel unmittelbar wieder so fest zusammen, daß die Öffnung 55 und der Vorratsraum 2 sogleich wieder dicht verschlossen sind. Um die Hohlnadel des Nachfüllbehälters zur Bohrung 34 genau ausrichten zu können, ist die Drucktaste 20 mit einer konzentrischen Ringnut 37 versehen, in die ein die Hohlnadel umgebendes Führungsrohr des Nachfüllbehälters einsteckbar ist.To refill the storage space 2 is in the longitudinal bore 22 of the push button 20 a wall 33 made of elastomeric material arranged accessible from the outside through a narrow bore 34 is and a pre-pierced, by the contraction behavior of material 55 is kept closed Has. Through the hole 34, the opening 55 of the wall 33 pierced with a hollow needle of a refill container and then fill in ink through the hollow needle. The air displaced when new ink is filled by constantly changing the pressure in the refill container aspirated intermittently via the hollow needle. The wall 33 seals the hollow needle when refilling and behaves like an automatically closing valve. She pulls up immediately after pulling out the hollow needle firmly together that the opening 55 and the pantry 2nd are immediately sealed again. Around the hollow needle Align the refill container exactly with hole 34 can, the push button 20 is concentric Provide annular groove 37 into which a surrounding the hollow needle Guide tube of the refill container can be inserted.

Um das Schließen des Trennventils 9 beim Nachfüllen von Schreibflüssigkeit durch die Öffnung in der Wand 33 sicherzustellen, empfiehlt es sich die Nachfülleinrichtung so auszubilden, daß die Hohlnadel die Wand 33 erst durchstoßen kann, nachdem durch Eindrücken der Drucktaste 20 das Trennventil 9 in seine Schließstellung gelangt ist. Dies kann beispielsweise dadurch erreicht werden, daß das in die Ringnut 37 eingreifende Führungsrohr des Nachfüllbehälters gegenüber diesem verschiebbar und an einer Druckfeder abgestützt ist, wobei die Federkraft dieser Druckfeder größer ist als die der Druckfeder 25 an der Drucktaste 20. To close the isolation valve 9 when refilling To ensure writing fluid through the opening in wall 33 it is recommended that the refill device is so form that the hollow needle only pierce the wall 33 can, after pressing the push button 20, the isolation valve 9 has reached its closed position. This can can be achieved, for example, in that the Ring groove 37 engaging guide tube of the refill container slidable relative to this and supported on a compression spring is, the spring force of this compression spring is greater is than that of the compression spring 25 on the push button 20th
