Definitions

  • the invention relates to a writing instrument for ink according to the Preamble of claim 1.
  • Such a writing instrument is known from DE 34 21 417 A1.
  • This font shows a fountain pen in the front Area of the shaft a lamella system for receiving or dispensing of ink is arranged.
  • One associated with an ink supply standing ink supply groove runs in one longitudinally extending plate carrier, of which transversely arranged and mutually spaced lamellae, also lamellar discs or Called fin fins, go out.
  • There is between these slats between the side of the slat carrier that is the open one Has side of the ink supply groove, and the inner wall of the A capillary gap over which ink emerges from the ink supply groove emerge into the space between the slats can.
  • the slats themselves extend over the essential Part of its circumference directly to the inner wall of the shaft.
  • the Slat system prevents that due to pressure or temperature fluctuations in the ink tank Ink flow occurs by absorbing excess ink and is returned if necessary.
  • the range is sufficient Slats of a group arranged transversely and spaced apart Slats, between which the open one Side of the ink supply groove side of the plate carrier and there is a capillary gap on the inner wall of the shaft, in a first area, which is in the area of the open Side of the ink supply groove, up to the inside wall of the pen barrel.
  • a second area facing away from the first area and extends over at least 80% of the circumference of the slats, keep the slats of the group at a distance from the inner wall of the shaft, which is so large that a capillary action is prevented.
  • This design of the slats ensures that the ink in the area of the first area of the group's slats the capillary gap to the inner wall of the shaft without problems the ink supply groove in the space between the lamellae enter or from this space back into the ink supply groove can reach, depending on the pressure and temperature conditions in the ink reservoir that is connected to the ink supply groove communicates.
  • the writing instrument according to the invention is very sensitive Pressure or temperature fluctuations in the storage container for the Ink-responsive slat system. The writing tip is thereby relieves the load reliably and prevents the formation of drops.
  • the range of Shaft in which the lamella system is arranged transparent or see-through.
  • Another advantage of the slat system becomes visible: Because on the edges of the slats of the group in the second area the ink cannot stick because there is no capillary action the slat system appears clean. It will just a longitudinal stripe on the inner wall of the Shaft wetted with ink that is close to the open one Side of the ink supply groove is located in the first area of the slats of the group. Because this strip is limited is, it does not act as "dirt" and can even do one produce an attractive aesthetic effect.
  • the distance preventing the capillary action is preferably at least 0.1 mm.
  • shape of the slats in the group is not important second area; you can e.g. circular, elliptical, be polygonal or irregular. Essential is that in the second area the distance to the inner wall of the Is so large that the ink is not under the effect of Capillary forces creep to the edge of the lamella and there permanently can remain.
  • the slats have the Group in the second area each serving a ventilation purpose Recess on.
  • the distance of the edge is in the recess of the respective lamella to the inner wall of the shaft is larger than in the remaining zones of the second area, creating a special reliable ventilation of the space between the slats the group is guaranteed. Ventilation is for the function of the slat system essential.
  • the writing tip can e.g. be designed as a pen.
  • the Ink supply groove not only with the reservoir for the Ink in combination, but also with the pen.
  • the Ink gets from the reservoir in a manner known per se via the ink supply groove to the writing tip.
  • the writing tip has one Writing ball on top of a wick with the ink supply in Connection is established.
  • the ink supply groove ends within the slat system and does not extend up to the writing tip. The ink is taken out over the wick, while the slat system is independent of this with the storage container for ink is connected to its pressure or temperature fluctuations balance.
  • Writing device 1 according to the invention is as an ink ballpoint pen designed.
  • Figure 1 shows the front region of a shaft 3, in which a Lamellar system 5 arranged for receiving or dispensing ink is.
  • Lamellar systems are known in principle and take in the event of pressure or temperature fluctuations in the ink reservoir Ink on or off again, causing a drop at the writing tip is avoided.
  • the lamella system 5 is made from one piece manufactured and in one piece with a tubular pen holder 6 connected, the concentric to the longitudinal axis L-L Writing utensil 1 runs out of the front end of the barrel 3 exits.
  • the nib holder 6 carries a nib 7, which has a rotatable ball at its front end 8 has.
  • the writing tip 7 is covered with a wick 9 Ink supplied.
  • the wick 9 protrudes with its rear end a reservoir for ink, which is in the back of the Shaft 3 is arranged, i.e. in the representation according to the figure 1 to the right of the lamella system 5, and not in the figures is shown.
  • the storage container not replaceable for ink.
  • the writing instrument according to the invention however, e.g. as cartridge filler with replaceable Cartridge designed.
  • the lamella system 5 has one in the direction of the longitudinal axis L-L of the writing instrument 1 extending slat carrier 10. Of the Lamellar carrier 10 is in its interior with a channel 12 Providing the wick 9. A direct link between the channel 12 and the outer space of the disk carrier 10 does not exist.
  • FIG. 2 shows a cross section of the lamella carrier 10 (hatched) along the line II-II from Figure 1.
  • the disk carrier 10 in the cross-sectional contour in the lower region 14 designed round, the radius is much smaller than that of the shaft 3.
  • the lamella carrier In its upper region 16 the lamella carrier is sufficient 10 almost up to the inner wall 22 of the shaft 3.
  • Die Terms “above” and “below” refer to those in Figure 2 shown orientation of the disk carrier 10.
  • an ink supply groove 18 is incorporated, which communicates with the ink reservoir.
  • a capillary gap 20 which also is called an overflow.
  • the capillary gap 20 on both sides of the ink supply groove 18 intended.
  • a capillary gap could just be on one side of the ink supply groove 18 between the upper area 16 of the disk carrier 10 and the inner wall 22 of the shaft 3, while the upper region 16 is on the opposite side of the ink supply groove 18 Inner wall 22 of the shaft 3 touches.
  • the capillary gap is 20 so narrow that under the action of capillary forces, ink spills out the ink supply groove 18 into the outside of the disk carrier 10 can cross.
  • slats On the disk carrier 10 are mutually spaced lamellae attached, their planes transverse to the longitudinal axis L-L of the writing instrument 1 run.
  • These slats can be in several groups be arranged, the slats of a group being the same or have largely the same cross-sectional contour.
  • two groups of slats are provided, namely the fins 24 described in more detail below with the in Figure 2 drawn cross-section (not hatched) and a another group 26, in which the edges of the slats have a larger one Have a distance to the inner wall 22 of the shaft 3.
  • the fins 24 are designed such as also shown in Figure 2 for the sake of clarity.
  • a first area 34 which is in the area of open side of the ink supply groove 18 is located at the capillary gap 20
  • the lamellae 24 each reach up to the inner wall 22 of the shaft 3. That is, they touch the inner wall 22 of the shaft 3 directly or they have one very small distance from it, which is even smaller than the width of the capillary gap 20.
  • a second region 36 which of The fins 24 hold away from the first region 34 each a distance from the inner wall 22 of the shaft 3.
  • the second area 36 extends over at least 80% of the Circumference of the fins 24, in the exemplary embodiment about 90% of the scope. Is on both sides of the ink supply groove 18 the transition zone between the first region 34 and the second Area 36 is relatively narrow, see FIG. 2.
  • a capillary action can usually be avoided if the Slats 24 in the second area 36 are each a distance of Comply with at least 0.1 mm to the inner wall 22 of the shaft 3. However, this distance can also be larger.
  • the cross-sectional contour can also of the slats 24 of the largely circular Contour according to Figure 2 may be different. The essential point is that the distance to the inner wall 22 should be greater than that Distance between two adjacent slats 24, so that by the then greater capillarity effect with respect to the distance to the inner wall there is ink sticking between the lamellae Internal wall is prevented.
  • the fins 24 each have within the second region 36 a recess 38 in the area of the distance to the inner wall 22 of the shaft 3 is larger than otherwise in the second region 36.
  • the recesses 38 of the slats 24 facilitate ventilation the chambers 28 between the fins 24. Further details the ventilation device for the lamella system 5 not shown in Figures 1 and 2. The ventilation that for the function of the lamella system 5 is essential in well-known way.
  • ink ballpoint pen shown in Figures 1 and 2 stands for the ink supply groove 18 with the reservoir Ink in connection, but ends in the front area of the lamella system 5, i.e. it does not lead to tip 7. If the nib is designed as a nib is against a connection between the ink supply groove and the Pen provided so that the ink over the ink supply groove from the ink reservoir to the nib becomes.
  • the channel 12 is omitted in this case.
  • the lamella system 5 serves as a compensation system, to check for pressure or temperature fluctuations in the ink reservoir Pick up or release ink.
  • the ink passes through the ink supply groove 18 through the respective capillary gap 20 in the chambers 28 between the Slats 24. Between the slats of the further group 26 can a larger amount of ink is absorbed; there is the distance between the ink supply groove 18 and the inner wall 22 of the shaft 3 so large that no capillary action occurs.
  • the lamella system 5 functions in a known manner, is due to the design of the cross-sectional contour of the slats 24 particularly powerful. Filling and emptying the Chambers 28 take place via the respective capillary gap 20, whereby a direct passage into the neighboring chambers by the design of those adjacent to the respective capillary gap 20 Slats 24 in the first area 34 is prevented.
  • the balancing effect of the slat system 5 is therefore sensitive.
  • In the second area 36 an undesirable effect on the lamella 24 Capillary action avoided.
  • the slat system 5 can therefore practically empty completely and there is no undesired drop formation on the writing tip 7.
  • the area of the shaft 3 in which the lamella system 5 is arranged is transparent or see through another advantage of the design of the slats 24.
  • the long run can only on the lamellae 24 ink in the respective first Area 34 remain, which from the outside is more longitudinal Stripe is visible.
  • the slat system appears in the other zones 5 on the other hand clearly. The impression of pollution arises Not.
