Definitions

  • a tubular nib writing implement has a head piece, whose lower end is adapted for the screwing in of a nib provided with a collar with a nut profile and the upper end of the head piece can be inserted with its upper end, which serves for receiving an ink cartridge, into a holding shank.
  • the shank is provided with a spanner recess corresponding to the nut profile of the nib. The spanner recess lies in the substantially cylindrical side wall of the holder shank.
  • the invention relates to tubular nib writing implements, and more particularly with a head piece, whose lower end is adapted for the screwing in of a nib provided with a collar with a nut profile and the upper end of the head piece can be inserted with its upper end, which serves for receiving a ink cartridge, into a holding shank, more particularly by screw means, and the shank is provided with a spanner recess corresponding to the nut profile of the nib.
  • One object of the present invention is to provide a tubular nib writing element with an interchangeable nib in the case of which the holding shankusedasawrench which cannot be lost makes possible a particularlyeffortless actuation of the writing nib even when the screw threads are jammed or blocked with vdriedink.
  • the wrench-recessin the holding shank lies opposite a diametrally placedpreferably-similarly shaped opening, through which on placing the holding shank in position as an actuating wrench extends onto the nib at its front end.
  • this through-hole for the front end of the writing nib as a recess similar to that of the wrench recess has the advantage that the holding shank can be placed as desired on one or the other side as a wrench, which also has the advantage that in the case of any damage or splitting of one of the wrench recesses a further wrench recess is available for use.
  • the wrench recess can be arranged in the lower part of the holding shank, in accordance with a further feature of the invention, into which the ink cartridge extends so that there is not only a large lever arm but there is also the possibility of examining the state of filling of the ink cartridge from the outside without any difficulty.
  • the wrench or key recess corresponding to the nut collar of the nib should not be taken only to include such recesses as whose peripheries exactly correspond to the periphery of the collar, but includes all forms of recesses which on placing on the nut collar can act as a key or wrench.
  • a wrench or key recess is arranged in the upper part of the holder shank, above the inwardly extending ink cartridge so that for removal of the writing nib of one implement another similar tubular nib writing implement can be used, that is, the holding shank of the one implement does not need to be removed at all.
  • the arrangement in order simultaneously to allow checking the level of the ink in the ink cartridge from the outside it is possible for the arrangement to be such that several wrench or key openingsare provided with axial spacing between them, at least one opening being arranged adjacent to the inwardly extending cartridge and at least one being arranged above the space in the holding shank occupied by the ink cartridge.
  • an injection molded part comprising the wrench recess and the oppositely placed openings can be injection molded in the holder shaft which ,ispreferably of adifferent color.
  • This injection moldedpart or these injection molded parts in the case of the provision of several such parts, are placed before injection molding of the holding shank in the corresponding mold.
  • the difference in color of the injection molded part and the holder shank offers simultaneously the possibility of color marking of different tubular nib writing implements in accordance with the line thickness of their nibs while the color of the injection molded part is preferably the same as the corresponding color of the writing nib.
  • the holding shank can advantageously be a sleeve which is substantially cylindrical and is open at both ends, since owing to the arrangement of the wrench or key recess in its side wall a covering surface is not absolutely necessary.
  • FIG. l is a view of a tubular nib writing element, partly in section.
  • FIG. 2 shows the holding shank mounted as a wrench or key on the writing nib and partly broken away.
  • FIG. 3 is a part view looking in the direction of the arrow P in FIG. 2.
  • a writing or drawing nib 2 can be screwed in, while at the upper end, into which an ink cartridge 3 can be inserted, a screw section 4 is provided, with whose help the head piece I can be screwed into a holding shank or cap 5.
  • two axially spaced hexagonal recesses or openings 6 and 7 are arranged which in shape and size correspond to a hexagonal nut collar 8 serving as a wrench or key engaging surface.
  • the recesses or openings 6 and 7 are opposite to correspondingly shaped recesses or openings 9 and 10, through which the writing nib ll can extend to the outside when the holding shank is mounted on the nib 2 for use as an actuating key.
  • Reference numeral 12 indicates the tip of a conventional cleaning wire, which is connected with a loading weight which can move to a limited extent inside the writing nib.
  • the invention is not limited to the embodiment shown. Thus it is possible not only to have a different number, arrangement, and shape of the wrench or key recesses and the passage openings arranged opposite them for the lower end of the writing nib, but also to provide a force fit of the holding shank on a correspondingly shaped fitting surface at the upper end of the head piece instead of screwing it on as is shown.
  • a tubular nib writing instrument comprising in combination:
  • a tubular grip member open at both ends for inserting an ink supply cartridge into one of the ends of the grip member, said one end of the grip member having fastening means for removably retaining one end of a closure cap, the other end of the grip member being threaded;
  • a tubular writing nib having at one end a threaded wall portion screwable upon the threaded grip member end, the other end of the nib constituting a writing end thereof, said nib mounting intermediate its ends a collar having an unround peripheral outline;
  • a tubular closure cap for covering an ink supply cartridge inserted into the grip member, said cap being removably fittable upon said fastening means on the grip member, and including in its side wall an opening having a peripheral outline matching the unround peripheral outline of the collar on the nib, whereby said cover cap constitutes a key for tightening or loosening said nib when the side wall opening thereof is fitted upon said collar.
