Description
DEUTSCHESGERMAN
Die Erfindung betrifft einen Druckkugelschreiber, bestehend aus einer Hülse, in der sich ein längsverschiebbarer, lediglich in seiner vordersten Schreibstellung mit seiner Schreibkugel aus der vorderen Hülsenspitze hervorragender und darin durch eine Riegelvorrichtung lösbar festgehaltener Schreibeinsatz befindet, und so eingerichtet, daß der aus einem Tintenbehälter und einer Schreibkugelhalterung bestehende Schreibeinsatz beim Eindrücken eines am hinteren Ende der Hülse angeordneten Druckorgans in dieHülse gegen denDruck einer in der Hülse gelagerten Schreibeinsatz-Rückholfeder in die Schreibstellung bringbar ist, wobei die Luft in dem Tintenbehälter mittels eines ebenfalls durch das Druckorgan vorschiebbaren, den Lufteintritt bzw. Luftaustritt in den bzw. aus dem Tintenbehälter steuernden Zylinders entgegen dem Druck einer Zylinder-Rückholfeder zusammenpreßbar ist.The invention relates to a retractable ballpoint pen, consisting of a sleeve in which a longitudinally displaceable, only in his foremost writing position with his writing ball from the front Sleeve tip excellent writing insert that is detachably held in it by a locking device is located, and arranged so that the consisting of an ink tank and a pen ball holder Writing insert when pressing in a pressure member arranged at the rear end of the sleeve into the sleeve against the pressure of a writing insert return spring mounted in the sleeve into the writing position can be brought, wherein the air in the ink container by means of a likewise pushable through the pressure element, the air inlet or air outlet in or out of the ink tank controlling cylinder the pressure of a cylinder return spring can be compressed.
Bei bekannten derartigen Druckkugelschreibern ist die in der Hülse gelagerte Feder, die zum Rückziehen des Schreibeinsatzes in die Hülse dient, wesentlich stärker als die Feder, durch deren Druck die Luft in dem Tintenbehälter mittels eines teleskopartig über diesen gleitenden Zylinders zusammengepreßt wird.In known ballpoint pens of this type, the spring mounted in the sleeve is used to retract of the writing insert in the sleeve is used, much stronger than the spring, the pressure of which moves the air into the ink container is compressed by means of a telescopic cylinder sliding over this cylinder.
Es wird also der Druck im Tintenbehälter schon erhöht, bevor die Schreibkugel in die Schreibstellung gebracht ist, so daß die Gefahr des vorzeitigen Ausfließens der Tinte besteht. Durch eine an sich bekannte Riegelvorrichtung wird der Schreibeinsatz in Schreibstellung festgehalten, nachdem der Zylinder seine vorderste Stellung erreicht hat.So the pressure in the ink tank is already increased before the writing ball is in the writing position is brought, so that there is a risk of premature leakage of the ink. By a known one Latching device, the writing insert is held in the writing position after the cylinder has its has reached the foremost position.
Bei einem Kugelschreiber treten, namentlich nach längerem Nichtgebrauch, zwei Schwierigkeiten auf: Die Tinte fließt nicht nach, weil sie eingetrocknet ist oder weil sich eine Luftblase in der engen Zuleitung festgesetzt hat, oder es fließt zuviel Tinte aus, weil der Druck im Tintenbehälter zu hoch ist. Die erste Schwierigkeit wird bei bekannten Kugelschreibern durch Mittel beseitigt, die den Luftdruck im Tintenbehälter beim Vorschieben des Schreibeinsatzes erhöhen. Dagegen hat man die zweite Schwierigkeit bisher nicht beheben können; denn die bekannten Kugelschreiber haben immer noch den Nachteil, daß beim Ansetzen der Schreibkugel oft Tintenkleckse entstehen.Two difficulties arise with a ballpoint pen, especially after it has not been used for a long time: The ink does not flow because it has dried up or because there is an air bubble in the narrow inlet line or the ink leaks out because the pressure in the ink tank is too high. The first Difficulty is eliminated in known ballpoint pens by means of increasing the air pressure in the ink container increase when advancing the writing insert. On the other hand, we have had the second difficulty so far can not fix; because the known ballpoint pens still have the disadvantage that when When the writing ball is attached, ink blots often appear.
Der Erfindung liegt die Erkenntnis zugrunde, daß die Druckerhöhung im Tintenbehälter erst dann erfolgen darf, wenn sich die Kugel bereits in Schreibstellung befindet. Um dieser Forderung gerecht zu werden, ist der eingangs genannte Druckkugelschreiber gemäß der Erfindung so ausgebildet, daß die Zylinder-Rückholfeder wesentlich stärker als die Schreibeinsatz-Rückholfeder ist, so daß der Schreibeinsatz in die Schreibstellung gebracht ist, bevor die Luft in dem Tintenbehälter durch den Zylinder zusammengepreßt DruckkugelschreiberThe invention is based on the knowledge that the pressure increase in the ink container only then takes place may if the ball is already in the writing position. To meet this demand are, the aforementioned ballpoint pen according to the invention is designed so that the cylinder return spring is much stronger than the writing insert return spring, so that the writing insert in the Writing position is brought before the air in the ink container is compressed by the cylinder Retractable ballpoint pen

und die Tinte dadurch zum Ausfließen gebracht wird, und daß die Riegel vorrichtung den Schreibeinsatz erstand the ink is thereby made to flow out, and that the locking device only the writing insert
a5 dann in der Schreibstellung festhält, wenn das Druckorgan nach dem Vorbringen des Schreibeinsatzes den Zylinder in seine vorderste Stellung gebracht hat.a5 then holds in the writing position when the pressure element has brought the cylinder to its foremost position after the writing insert has been brought forward.
Durch den Druck auf das Druckorgan wird also zuerst die Schreibkugel aus der Hülse vorgeschoben und dann der Zylinder vorwärts bewegt, so daß die Tinte unter dem erhöhten Luftdruck der Kugeltülle zufließt. Durch eine Riegelvorrichtung werden die Schreibkugel und zugleich der Zylinder in ihrer Lage festgehalten. Der erhöhte Druck im Tintenbehälter hält so lange an, bis eine entsprechende Menge an Tinte verbraucht ist oder die Luft durch eine undichte Stelle entweicht. Auf jeden Fall erfolgt der Ausgleich des Druckes im Tintenbehälter auf den Außendruck beim Lösen der Riegel vorrichtung durch ein Luftloch in der Seitenwandung des Zylinders.As a result of the pressure on the pressure element, the writing ball is first pushed out of the sleeve and then the cylinder is moved forward so that the ink flows under the increased air pressure of the spherical nozzle. The writing ball and the cylinder are held in place by a locking device. The increased pressure in the ink tank continues until a corresponding amount of ink is used up or the air escapes through a leak. In any case, the pressure is equalized in the Ink container on the external pressure when releasing the locking device through an air hole in the side wall of the cylinder.
