Definitions

the invention relates to an ink conductor for fountain pens with capillary ink chambers arranged in the interior of the holder shaft front part on both sides of the ink conductor core 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 holder shaft front part and incorporated into the ink conductor, each individual chamber being connected to a ventilation channel which is common to all the chambers and leads to the outside.
the longitudinal ventilation duct overlaps the comb-like ink chambers and connects them to the outside air.
the object of the invention is to provide an ink guide with ink chambers which can be produced with comparatively simple molding tools and which is connected to the outside air via a functionally reliable ventilation and venting channel.
the function of the capillary ink chambers is to be improved and their manufacture is to be facilitated.
the ventilation channel is formed by a longitudinal groove formed in the underside of the ink guide and not connected to the ink chambers either in front or on the long sides, and in that the holder shaft front part itself or a sleeve inserted into the front part the underside is provided with an inwardly projecting longitudinal rib which engages longitudinally in the groove in the ink duct with lateral pressure and thus closes the ventilation channel formed by the longitudinal groove on both longitudinal sides in an ink-tight manner.
the lower half of the ink duct containing the ventilation channel is, according to the invention, set off from the upper half of the ink duct up to or almost to the middle plane of the ink duct and shortened so far at the rear that A free, practically capillarity-free space is created above the open end of the ventilation duct, in which the ink cannot find a capillary hold.
the ink should not normally enter the ventilation channel (longitudinal groove in the ink duct), that is, with ink chambers filled to the maximum limit of their absorption capacity. Penetration of the ink into the ventilation channel from the ink chambers prevents the longitudinal groove from being sealed. The capillary-free space protects the open end of the ventilation duct from the penetration of the ink.
the front end of the longitudinal groove forming the ventilation channel in the ink conductor may be endangered, namely in the case of excess ink, by vagabonding ink running around the front edge of the sleeve, e.g. B. with insufficient sealing in the pen area.
the part of the ink conductor which protrudes from the sleeve and is tapered on its underside after the nib of the pen does not begin at the edge of the sleeve but only further forward, at a small distance (about 1 to 2 mm) from the edge of the sleeve the longitudinal rib in the sleeve is extended forward over the edge of the sleeve to the bevel on the underside of the ink guide, where it is flush with the surface, and that the extended part of the longitudinal rib closes the longitudinal groove outside the sleeve, so that the ink from the sleeve edge cannot reach the longitudinal groove forming the ventilation duct.
the invention also relates to the ink chambers in connection with the ventilation duct. These usually consist of narrow comb-like incisions in the ink conductor on both sides of the ink conductor core, where they extend from top to bottom into the lower half of the ink conductor. Such ink chambers can only be produced with complicated and expensive molding tools.
longitudinal ink chambers arranged on both sides of the ink conductor core are simpler and cheaper to manufacture, which are formed by the side surfaces of the ink conductor core running parallel to the plane of symmetry of the ink conductor on the one hand, the lateral inner surfaces of the sleeve on the other hand and the inner and outer side surfaces by longitudinal ribs arranged therebetween.
the longitudinal ribs are connected to the ink conductor body at the front and rear and, in between, also to the core to increase the strength.
the longitudinal ribs in their lower part are dimensioned shorter at the back than the offset ink guide core containing the ventilation channel.
the ink chambers in the upper half of the ink guide extend to the rear end of the longitudinal ribs connected to the ink guide body.
the longitudinal ribs in the area of the core heel and the capillarity-free tree are connected to one another in the middle plane. This also means the free space behind the Ventilation channel in the middle plane closed except for the ink chambers on the outside, which is important for the function of the free space.
Laying the air channel away from the ink duct into the wall of the sleeve improves the control of the ink flow because the channels connecting the ink supply channel to the ink chambers (e.g. transverse cuts in the core) do not overlap the air channel and therefore do not disturb the fluctuation of the ink in the air channel .
the replacement air When writing, the replacement air must be able to penetrate the air duct from the outside through the ventilation duct and the ink chambers.
the air duct is connected to the ink chambers at its front end by a special recess in the ink conductor core that does not overlap the air duct.
the recess is dimensioned so that no more air penetrates into the air duct filled with fluctuating ink when writing than ink is consumed during writing.
the arrangement of the air inlet opening at the front end of the air duct worked into the sleeve effects a good regulation of the ink flow in the desired strength.
the longitudinal ink chambers according to the invention have a high, practically sufficient capacity.
the invention solves the problem in that the longitudinal ink chambers arranged on both sides of the ink conductor core, as described above, are only incorporated into the lower half of the ink conductor, which is delimited by the central plane, and that these ink chambers are only incorporated into the upper half of the ink conductor , comb-like ink chambers known per se extending transverse to the longitudinal axis are supplemented. In this way, an optimal use of space inside the sleeve and a higher absorption capacity of the ink chambers is achieved, without making the ink guide much more difficult than with the simple longitudinal ink chambers.
the object of the invention is shown in two exemplary embodiments on two sheets of the drawing. 1 to 5 on sheet 1 of the drawing show an ink duct with a ventilation channel and longitudinal ink chambers and FIGS. 6 to 10 an ink duct with a ventilation channel and with longitudinal and transverse ink chambers connected to one another in the central plane of the ink duct.
the ink conductor is in the drawings with 1, the sleeve surrounding it with 2 and the nib with 3.
the ink supply channel 4 leading to the nib 3 and incorporated into the core 10 is located on the upper side of the ink conductor 1.
the air channel 5 leading to the ink container is incorporated into the wall 18 of the sleeve 2, which is reinforced towards the inside.
the nib 3 is attached by tight fit of the tin conductor 1 in the mouth region of the sleeve 2.
the longitudinal ink chambers 7.1 and 7.2 Located on both sides of an ink conductor core 10 the longitudinal ink chambers 7.1 and 7.2. They are formed by the side surfaces of the core 10 on the one hand, the lateral inner surfaces of the sleeve 2 on the other hand and the inner and outer side surfaces by longitudinal ribs 9 arranged between them.
the longitudinal ribs 9 are connected at the front and rear to the body of the ink conductor 1 and between them also in part by short webs 15 connecting the longitudinal ribs 9 to the core 10.
the ventilation channel is formed by the longitudinal groove 11 and the longitudinal rib 12 engaging in it.
the ink guide 1 is beveled after the nib 3.
the bevel 19 ends, seen from the tip of the nib, about 1 to 2 mm in front of the edge of the sleeve 2.
the longitudinal groove 11.1 and the longitudinal rib 12.1 closing it are extended forward over the edge of the sleeve 2 to the bevel 19, where they coextensive with this end.
the ink chambers 7.1 and 7.2 are connected by cross cuts 16 in the core 10 to the ink supply channel 4 and by a recess 17 in the core 10 to the air channel 5. For better guidance and positioning of the core 10, it is slightly sunk in its entire width into the wall 18 of the sleeve 2.
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 upper half of the ink guide.
Both ink chambers, 6 and 7.l are connected to one another in the middle plane Y crosswise, as are also the transverse ribs 8 with the longitudinal ribs 9.
the outside longitudinal ink chambers 7.2 are extended upwards beyond the middle plane Y, where they meet with the comb-like ink chambers 6 are connected longitudinally.
the exemplary embodiment according to FIGS. 6 to 10 corresponds to the exemplary embodiment according to FIGS. 1 to 5.
