Definitions

  • the invention relates to a writing instrument for liquid writing media with a writing wick which can be inserted into an opening in the tip of a housing and which projects with its inner end into a memory for the writing medium.
  • Writing instruments of this type are equipped with very different writing wicks in generally the same housing dimensions depending on the type of use.
  • the holding means for the individual wicks are also designed correspondingly differently in the housing of the writing instruments.
  • the fiber wick is arranged in the bore of a plastic sleeve which is inserted into the opening in the tip of the housing of the writing instrument.
  • the plastic sleeve has ventilation channels running in the longitudinal direction within the bore, which are used for ventilation of the ink reservoir.
  • cams are provided in the bore of the plastic sleeve between the ventilation channels, which press inwards when the sleeve is pulled into the housing and thus clamp the writing wick.
  • the invention has for its object to provide a writing instrument for liquid writing media of the type mentioned, which is simple in construction and is suitable for the installation of different types of wick.
  • this object is achieved in that a membrane is arranged in the interior of the housing behind the opening and transversely to its longitudinal axis, into which an opening of size and shape adapted to the writing wick has been pushed before the insertion of the writing wick and which passes through the writing wick without play.
  • This has the advantage that the writing wick is precisely guided and aligned when inserted into the housing, so that it is pre-loaded seen direction penetrates into the memory for the writing medium and the writing medium can be sucked in unhindered by the wick.
  • the membrane resiliently spans the writing wick used and thereby reliably clamps the writing wick in the housing.
  • the clamping effect is increased by protruding the edge of the membrane surrounding the opening, which is formed when the wick is inserted.
  • a particularly advantageous embodiment of the invention is that the membrane has the shape of a cone, which is arranged coaxially to the longitudinal axis of the opening in the housing and the tip of which is directed towards the memory for the writing medium.
  • This conical shape of the membrane centers the inner end of the wick when it is inserted into the housing and facilitates the insertion of the wick.
  • the cone shape of the membrane prevents faults, particularly in the case of automatic wick assembly.
  • this conical shape of the membrane favors the protuberance of the membrane when inserting the writing wick and thereby reduces the risk of the writing wick buckling when inserted.
  • a particularly favorable guidance and holding of the writing wick is achieved if the membrane has the shape of a hyperboloid after the insertion of the writing wick.
  • the opening in the tip of the housing has longitudinally extending guide ribs which are extended beyond the opening to the storage for the writing medium and carry the membrane at their extended ends.
  • a ventilation of the memory for the writing medium is ge via the space between the guide ribs in the writing instrument according to the invention create by connecting these spaces around the outer edge with the storage.
  • An additional stabilization of the support of the membrane is advantageously achieved in this embodiment in that the elongated ends of the guide ribs are supported by retaining webs which extend in the radial direction up to the wall of the housing.
  • the guide ribs preferably have the shape of a triangular prism which faces the wick in one edge. The edge of the guide ribs can therefore easily penetrate the wick and thereby secure it against twisting. In addition, diameter tolerances between the wick and the opening can be easily compensated for.
  • a simplification of the writing instrument according to the invention is advantageously achieved in that the outer edge of the membrane forms an axial stop for a stepped wick. This is particularly advantageous for thick wicks that completely fill the opening in the housing. In addition, this position of the stop allows a particularly slim transition from the outer contour of the housing to the writing tip of the writing wick.
  • a further development of the invention consists in an advantageous method for assembling writing implements according to the invention.
  • the membrane formed in the housing is pierced by a profile mandrel inserted through the opening of the housing and corresponding to the type of wick to be assembled, and after the profile mandrel is pulled out, the writing wick is inserted into the opening until it stops.
  • the writing wick can easily be inserted into an already finished housing with a storage medium filled with writing medium.
  • Good alignment of the profile mandrel and housing when piercing the membrane is thereby advantageous achieved that the profile mandrel is centered on the guide ribs of the housing. No additional external guides are therefore required to align the profile mandrel and housing. Manufacturing tolerances with regard to the position of the opening relative to the outer contour of the housing can be disregarded.
  • FIG. 1 shows the top of the housing 1 a S chreib- device before mounting a writing wick.
  • the housing 1 is designed as a plastic injection molded part. It has an opening 2 with longitudinal guide ribs 3 for receiving the writing wick, between which intermediate spaces 4 are formed.
  • the guide ribs 3 have the shape of triangular prisms, the ends of which point toward the outer mouth of the opening 2 are rounded.
  • the guide ribs 3 are extended beyond the edge of the opening 2 and carry at their end a conical membrane 6, the tip of which is directed towards the interior 5 is.
  • Radial retaining webs 7 connect both the membrane 6 and the elongated ends of the guide ribs 3 to the tapered outer wall of the housing 1. Between the retaining webs 7 and the elongated ends of the guide ribs 3 there are cavities 8 which communicate with the spaces 4 and the interior 5 stay in contact.
  • the guide ribs 3 are formed by longitudinal grooves in the core forming the bore 2 and the holding webs 7 are formed by radial slots in the front end of the core forming the interior 5.
  • the housing 1 shown is suitable for inserting different types of writing wicks.
  • the membrane is used to adapt the housing 1 to the respective writing wick 6 pierce during the assembly process using a profile mandrel corresponding to the respective wick.
  • the inner end of the writing wick penetrates the opening pushed into the membrane and thereby receives an additional, form-fitting support in the housing 1.
  • the restoring properties of the plastics from which the housing 1 is produced the positive fit between the membrane and the wick used after assembly is increased.
  • the conical shape of the membrane centers the inserted wick end and prevents the writing wick from buckling when inserted.
  • FIGS. 3.1 and 3.2 show the insertion of a thin, metal-enclosed writing wick into the housing 1.
  • the membrane 6 is first pierced by a profile mandrel 10 with a tip 9.
  • the diameter of the profile mandrel 10 corresponds approximately to the diameter of the writing wick 11.
  • the writing wick 11 is then inserted into the puncture in the membrane.
  • the writing wick 11 has a metal sleeve 12 which is held between the guide ribs 3.
  • the metal sleeve 12 and the membrane 6 ensure double storage of the writing wick 11 in the housing 1. With its thicker shaft 13, the profile mandrel slides on the guide ribs 3.
  • Figure 4.1 shows the piercing of the membrane 6 with a profile mandrel 14 of cylindrical basic shape, the front end of which has a flat 15 lying in the central plane, and the end face is chamfered to form a cutting edge 16.
  • the profile mandrel 14 guided on the guide ribs 3 uses its cutting edge 16 to separate the membrane 6 from the guide ribs 3 on one side and bends it laterally.
  • a writing wick 17 divided at its end is inserted into the opening prepared in this way set.
  • the writing wick 17 is brought into the position corresponding to the position of the profile mandrel by a wick dividing device upstream of the assembly station for the subsequent assembly and is inserted into the housing 1 by the assembly device in this position.
  • the writing wick 17 reaches the end position shown in FIG. 4.2, in which it rests with its step surface 19 on the stop 18 formed by the membrane 6.
  • the described configuration of the receptacle for the writing wick 17 effectively prevents the writing wick 17 from tilting when it is inserted into the housing 1.
  • the outer edge 20 of the membrane 6 which remains after the membrane 6 has been pierced by means of the profile mandrel 14 engages around the outer surface of the writing wick 17 without play and thereby forms an additional support.
  • FIGS. 5.1 and 5.2 The assembly of an unmounted, cylindrical writing wick with a stepped lateral surface is shown in FIGS. 5.1 and 5.2.
  • the membrane 6 is pierced and expanded with a profile mandrel 21.
  • the unmounted wick 22 is then inserted into the housing 1 until its step 23 abuts the stop 24 formed by the outer edge of the membrane 6.
  • the widened section of the membrane 6 ensures that the writing wick is firmly clamped and thereby forms a good holder for the writing wick in the axial and radial directions.
  • the exemplary embodiment described is suitable for producing the housing 1 from a crystalline or also from an impact-resistant, amorphous plastic.
  • the types of wick used can consist of resin-bonded fibers or sintered powder. Extruded wicks with longitudinal capillaries are also suitable for the housing design according to the invention. Due to the high holding forces that can be achieved with the membrane 6 additional holding means such as pens or adhesives are not required.
