Definitions

  • the invention relates to an ink conductor for fountain pens with capillary ink chambers arranged on the inside of the holder shaft front part on both sides of the ink conductor core for receiving the excess ink and with a ventilation channel connecting the ink chambers with the outside air.
  • Fountain pens are known with comb-like ink chambers arranged in the interior of the front of the holder shaft and incorporated into the ink guide, each individual chamber being individually connected to a ventilation channel leading to the outside for all chambers.
  • the longitudinal ventilation duct overlaps the comb-like ink chambers and connects them to the outside air.
  • a fountain pen with a longitudinal groove which is worked into the wall of the sleeve (front part) and which is closed inwards by the flat underside of the ink conductor and serves as an air supply channel (French patent specification 1,471,265).
  • the longitudinal groove is directly connected at its rear end to the ink supply channel and in particular also to the air channel leading to the ink container.
  • the longitudinal groove therefore only serves to supply the air to the ink tank when writing. Ink chambers for holding the excess ink are not provided.
  • the short longitudinal groove in the area of the spring seat is therefore not a ventilation duct in the sense of the technical field specified in the introduction, to which the invention relates.
  • the object of the invention is to provide an ink guide which can be produced by spraying using comparatively simple molding tools, the ink chambers of which are connected to the outside air via a functionally reliable ventilation and venting channel.
  • the ventilation channel is formed by a longitudinal groove incorporated into the underside of the ink conductor core and connected to the ink chambers at the front again at the sides, in that the holder shaft front part itself or a sleeve inserted into the front part with an inwardly projecting sleeve Longitudinal rib is provided, which engages in the longitudinal groove with a lateral tight fit and thus closes the ventilation channel on its long sides ink-tight, and that the lower half of the ink duct containing the ventilation duct is offset from the upper half of the ink duct at the rear end of the ink duct and shortened to the rear so that behind the at the rear open end of the ventilation duct, a free, practically capillarity-free space is created in which the ink cannot find a capillary hold.
  • the known ink chambers generally consist of comb-like incisions extending from top to bottom into the lower half of the ink conductor on both sides of the ink conductor core.
  • Such ink chambers can only be produced by spraying with very precise and expensive molds.
  • Easier and cheaper to manufacture are longitudinal ink chambers arranged on both sides of the ink conductor core, which are formed by side surfaces of the ink conductor core running parallel to the plane of symmetry of the ink conductor on the one hand, the inner side surfaces of the sleeve surrounding the ink conductor on the other hand and the inner and outer side surfaces by longitudinal ribs arranged between them.
  • the combination of the described longitudinal ink chambers with the transverse comb-like ink chambers known per se is particularly advantageous for the function of the ink chambers and also for their production.
  • the combination is that the longitudinal ink chambers arranged on both sides of the ink conductor core are only incorporated into the lower half of the ink conductor, which is delimited by the middle plane, and that these ink chambers are supplemented by transverse comb-like ink chambers only incorporated into the upper half of the ink conductor.
  • the inside of the sleeve for the tin The available space is optimally used and the ink chambers have a higher absorption capacity.
  • FIGS. 1 to 5 show an ink duct with the ventilation channel according to the invention and with only longitudinal ink chambers on both sides of the ink conductor core
  • FIGS. 6 to 10 show an ink duct according to the invention with combined longitudinal and transverse ink chambers.
  • the ink conductor is in the drawing with 1, the sleeve surrounding it with 2 and the pen with 3.
  • On the top of the ink conductor 1 is the ink supply channel 4 leading to the nib and incorporated into the core 10.
  • the air channel 5 leading to the ink container is embedded in the inwardly reinforced wall 18 of the sleeve 2. The routing of the air channel 5 away from the ink duct into the wall of the sleeve facilitates the manufacture and improves the exchange of air and ink in opposite directions during writing.
  • the replacement air When writing, the replacement air must be able to penetrate into the air duct 5 filled with an ink-air mixture. Therefore, the air channel 5 is provided at its front end by a recess 17 incorporated in the ink conductor core 10, which is dimensioned such that only as much air penetrates into the air channel 5 when writing as ink is consumed.
  • the longitudinal ink chambers 7.1 and 7.2 are located on both sides of the ink conductor core 10 (FIGS. 1 to 5).
  • the longitudinal ribs 9 forming them are located between them.
  • the longitudinal ribs are connected to the ink conductor body at the front and rear and in places also by short webs 15 to the ink conductor core 10.
  • the longitudinal ink chambers 7.1 and 7.2 are only incorporated into the lower half of the ink guide.
  • transverse comb-like ink chambers 6 are incorporated into the ink guide on both sides of the core 10. Both ink chambers, 6 and 7.1, are connected in a crosswise manner in the central plane Y, as are the transverse ribs 8 with the longitudinal ribs 9.
  • the outer longitudinal chambers 7.2 extend upwards beyond the central plane Y into the upper half of the ink guide, where they communicate with the transverse ink chambers 6.
  • the ink chambers 6 are connected to the ink supply channel 4 at the top by very narrow, air-permeable transverse incisions 16 in the core 10 of the ink conductor 1.
  • the ventilation channel is formed by the longitudinal groove 11 and the longitudinal rib 12 engaging in it.
  • the lower ink duct half containing the ventilation channel (longitudinal groove 11) is offset at the rear from the upper half to almost the central plane Y and is shortened by a few millimeters. In this way, a practically capillarity-free space 14 is created above the rear open end of the ventilation channel, in which the ink cannot settle and close the ventilation channel.
  • the longitudinal ribs 9 are dimensioned shorter in their lower part at the rear than the ink duct core 10 containing the longitudinal groove 11
  • Outer longitudinal ink chambers 7.2 extend to the rear end of the ink guide, where they are connected to the air chamber 14.
  • the inner ink chambers 7.1 also extend in the upper half of the ink guide to the rear end of the ink guide, but it is separated from the air chamber 14 in the rear region by the ribs 15 closing them in the central plane Y.
  • the air chamber 14 (capillary-free space) protects the end of the ventilation channel which is open at the rear from flooding.
  • the front end of the ventilation channel is at risk from vagabonding ink running around the front edge of the sleeve 2, e.g. in the event of insufficient sealing of the ink guide seat in the area of the nib 3's exit from the sleeve 2. This is prevented by the fact that the front end of the ventilation channel is advanced to the part of the ink guide which is chamfered on the underside after the nib of the nib.
  • the bevel 19 does not begin at the edge of the sleeve 2, but only further forward, about 1 to 2 millimeters from the edge of the sleeve 2.
  • Longitudinal groove 11 and longitudinal rib 12 are shown up to the bevel 19, where they terminate with the same area.
  • the extended part 12.1 of the longitudinal rib 12 also closes the longitudinal groove 11.1 outside the sleeve 2, so that ink cannot get to and into the ventilation channel from the edge of the sleeve.
