Definitions
- the subject of the application is a writing instrument of the type mentioned in the preamble of the main claim.
- liquid ink is placed on the writing pad in this device via a tube.
- a wire or wick-shaped writing element is arranged in the tube and forms ink supply channels with the inner wall of the tube.
- This writing wick protrudes from the outside of the tube and forms the tip of the writing. It is axially displaceable in the tube against the action of a spring element.
- the spring element ensures that the writing tip remains in contact with the writing pad in every writing position.
- the axial movement of the writing wick that occurs automatically during writing removes impurities from the writing tube.
- the pumping effect that occurs when the writing tip is attached supports this effect.
- this spring element consists of an ink-permeable foam plastic cushion or the like.
- This foam plastic pillow has two disadvantages.
- the restoring force of the pillow decreases over the course of use, which can impair the functionality of the writing instrument.
- a foam plastic cushion with the density required for elasticity has only limited ink permeability.
- non-pigmented inks In order to achieve a better open storage capacity with writing instruments of this type than with known tube writing instruments, non-pigmented inks must be used instead of the pigmented inks. The latter are known to have a much higher opacity than non-pigmented inks. In order to achieve a comparable blackening and opacity of the lines created with the inks, more intensive ink delivery is required. However, this is not guaranteed in the writing instrument resulting from DE-OS 30 23 189, in particular due to the foam plastic cushion.
- the present invention is based on the object of improving the ink flow in such writing instruments, in particular to achieve a higher volume of ink output based on the writing path.
- This object is generally achieved by improving the ink flow in the area of the inner end of the writing element.
- FIG. 1 shows an axial section of a writing device designed according to the invention in the area of the writing tip with the indicated closure cap according to a first exemplary embodiment
- the ink storage located in the rear part of the housing 10, from which the liquid ink is transported by means of the ink guide 11 into the front area of the writing tip due to the capillary action of the ink guide.
- the writing wick 30 is preferably made of thermoplastic Material and has axially extending capillary channels 33 in its outer surface, as the section according to FIG. 3 illustrates.
- the writing wick 30 is thickened to a spherical head 31.
- a spring element is inserted into the sleeve 20, which consists of a ring 40 with a return spring 41 projecting into the ring interior.
- This return spring is designed and arranged, as can be seen from the section according to FIG. 5, that unhindered ink escaping can reach the wick 30.
- axially extending capillary channels 42 and 43 are also arranged on the outer and inner lateral surface of the ring 40. These guide the ink emerging from the ink conductor 11 to radially extending collecting channels 23 which are injected into the sleeve 20 (cf. FIG. 4).
- the return spring 41 ensures that the longitudinally movable writing wick 30 is pressed against the writing pad, so that the contact with the writing pad is in every writing position. is maintained.
- insertion and removal "of the Schreib ⁇ tip of the writing wick 30 against the action of the return spring 41 is moved axially, whereby on the one hand, are removed by mechanical action and on the other hand, by effectively Pump ⁇ impurities from the Schreibr ⁇ hrchen 32nd
- the return spring 41 also brings about a soft support of the writing tip on the writing pad, which leads to a pleasant feeling when drawing and writing.
- the writing tube is provided with a hard material zBTitan nitride coating "32, which also ensures an absolute ⁇ briebfesttechnik and KorrisionsDisp at all temperatures.
- the inner lateral surface of the sleeve 20 is provided with preferably injected, axially extending capillary channels 22 (cf. FIG. 6). This ensures that the ink is guided not only over the end face 11a of the ink guide, but also to a not inconsiderable extent over the outer face 11b of the ink guide.
- the ink supplied via the capillary channels 22 reaches the annular capillary gap 24 via the radial channels 23.
- An air duct 21 provided in the sleeve 20 connects the outside air to the annular air space 13 surrounding the ink conductor, which in turn is connected to the ink reservoir (not shown), by means of which the latter is vented when ink is dispensed.
- writing implements designed according to the invention can be stored for much longer than conventional inking implements working with pigmented ink. Storage capacities of more than one year can be achieved if, as indicated with FIG. 1, the writing tip is covered with a closure cap 50.
- a sealing ring 51 resting on the outer surface of the sleeve 20 ensures that the space in the region of the front end of the writing tip is sealed and has only a small volume.
- a writing wire 30 ' is recommended instead of the writing wick 30 made of plastic, as is illustrated with FIG. 2.
- a ball head 31 * preferably made of plastic, is injection molded onto its inner end, against which the return spring 41 bears. Otherwise, the functioning of this writing instrument corresponds to that of the writing instrument according to Fig. 1
- the capillary system designed according to the invention ensures that the writing medium is fed to the writing tip evenly and in sufficient quantity without delay.
- the writing instrument is designed so that due to its. einfa.ciej ⁇ , -_ f.ert Trentsstieri.ten construction cost-effective production is possible.
- the writing instrument essentially consists only of the housing 10, the socket 19, the sleeve 20 with the writing tube 32 and the writing wick 30, the spring element with the ring 40 and return spring 41, the ink conductor 11 and the ink reservoir (not shown). All parts are designed so that they can be manufactured and assembled using simple tools.

Abstract
Un appareil d'enregistrement du type à tube, qui possède à son extrémité avant un petit tube d'écriture (32) avec une mèche (30) d'écriture qui se déplace axialement à l'intérieur. La mèche d'écriture (30), qui posséde à son extrémité interne une tête sphérique (31) épaissie, peut être enfoncée contre l'action d'un ressort de rappel (41). Le ressort de rappel (41) fait partie d'un anneau à élément à ressort qui est inséré entre l'alimentation en encre (11) et la mèche d'écriture (30) dans le boîtier (20). L'anneau (40) et le ressort de rappel (41) sont dimensionnés de telle sorte que l'encre qui sort du conduit d'alimentation en encre (11) parvienne sans obstacle et en quantité suffisante à la mèche d'écriture (30).A tube type recording apparatus, which has at its front end a small writing tube (32) with a writing wick (30) which moves axially therein. The writing wick (30), which has at its internal end a thickened spherical head (31), can be pressed against the action of a return spring (41). The return spring (41) is part of a spring element ring which is inserted between the ink supply (11) and the writing wick (30) in the housing (20). The ring (40) and the return spring (41) are dimensioned so that the ink which leaves the ink supply duct (11) reaches the writing wick (30) unimpeded and in sufficient quantity. ).
