Definitions

  • the subject of the application is a writing instrument of the type mentioned in the preamble of the main claim.
  • liquid ink is brought over a tube on the writing pad.
  • a wire-shaped 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 beyond the outer end of the tube and forms the writing tip with it. 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 contaminants 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 shelf life 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, particularly due to the foam plastic cushion.
  • This object is generally achieved by improving the ink flow in the area of the inner end of the writing element.
  • the ink reservoir 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.
  • a socket 19 is inserted with a coaxially pressed-in sleeve 20.
  • the sleeve 20 receives on one end the front end of the ink conductor 11 and on the other side carries the writing wick 30 stored in the writing tube 32.
  • the writing wick 30 is preferably made of thermoplastic material and has axially extending capillary channels 33 in its outer surface. as the section of 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 the section according to FIG. 5 shows that the ink emerging from the ink conductor 11 can reach the writing wick 30 without hindrance.
  • 40 axially extending capillary channels 42 and 43 are also arranged on the outer and inner lateral surface of the ring. 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 during the writing process that the longitudinally movable writing wick 30 is pressed against the writing pad, so that contact with the writing pad is maintained in every writing position.
  • the writing wick 30 is moved axially against the action of the return spring 41, as a result of which impurities are removed from the writing tube 32 on the one hand by mechanical action and on the other hand by pumping action.
  • 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 inner lateral surface of the sleeve 20 is provided with preferably injected, axially extending capillary channels 22 (cf. FIG. 6). It is hereby achieved 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.
  • the ink discharged through the capillaries 42 and 43 on the end face of the ink conductor crawls capillary between the ring 40 and the end face of the bore in the sleeve 20 to the radial channels 23 and thus also reaches the annular gap 24.
  • An air channel 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), as a result 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 over a year can thus 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 area 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.
  • this writing wire 30' delimits a capillary annular gap 33 ', via which ink is transported to the writing tip in the same way as with the capillary channels 33.
  • a ball head 31 ′ preferably made of plastic, is injection molded onto its inner end, against which the return spring 41 bears.
  • the capillary system designed according to the invention ensures that the writing medium is fed to the writing tip without delay, evenly and in sufficient quantity.
  • the writing instrument is designed in such a way that, due to its simple, production-oriented structure, it is possible to produce it inexpensively. So the writing instrument consists essentially of the housing 10, the socket 19, the sleeve 20 with the writing tube 32 and the wick 30, the spring element with 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 with 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).
