Definitions

  • the invention relates to an ink conductor for a fountain pen, with a main body having radial ink receiving chambers, the rear end of which can be connected to the ink reservoir of the ink fountain pen and which has an axially extending groove on the spring support side for receiving an insert, between and the bottom of the groove an air duct and at least one capillary ink supply duct are formed.
  • two capillary ink supply channels run in the groove base of the air channel formed in the main body and connect the rear end of the main body to the spring support surface, the two ink supply channels in the region of the front end of the main body otherwise deviate from a straight line and are curved in the direction of the spring support surface, so that they emerge there and there is a direct wetting of the underside of the spring with ink from the ink supply channels.
  • an ink conductor of the type mentioned at the outset is designed in such a way that the front end of the ink supply channel opens into an ink cushion space formed between the main body and insert part and that the ink cushion space has a capillary ink outlet gap with the spring contact surface which is present between the front end region of the insert part and main body is connected, which extends from the axial center plane of the ink conductor running through the center of the groove to the two sides thereof and at least with partial sections to the rear.
  • the ink is not supplied to the spring directly from the capillary ink supply channel or from the capillary ink supply channels, but from an ink cushion space fed by the latter, so that even in the event of greater ink consumption, this forms a kind of buffer Ink pad room sufficient ink can be sucked up.
  • the supply of the ink from the ink cushion space to the nib takes place via a capillary ink outlet gap, which lies with its front area directly below the nib slot and extends both to the side and to the rear, so that in the idle state or with little writing pressure, the nib is wetted over the entire Ink outlet gap including the area immediately below the spring slot takes place, even if the spring is not arranged exactly in the center.
  • a capillary ink outlet gap which lies with its front area directly below the nib slot and extends both to the side and to the rear, so that in the idle state or with little writing pressure, the nib is wetted over the entire Ink outlet gap including the area immediately below the spring slot takes place, even if the spring is not arranged exactly in the center.
  • the ink film between the region of the ink outlet gap and the spring lying immediately below the spring slot can be interrupted, but an ink film reliably remains, which closes between the remaining region of the ink outlet gap and the spring both sides of the spring slot.
  • the ink exit gap can, for example, be U-shaped, the legs of the U extending rearward and diverging rearward, and the transition from the base of the U to its legs being able to take place over a rounded region or over an angular region.
  • ink outlet gap V-shaped it is also possible to make the ink outlet gap V-shaped or to make it arcuate, so that the ends of the sheet lie further back than the central region thereof.
  • the distance between adjacent wall areas of the main body and insert part which delimit the ink cushion space can continuously decrease from the mouth area of the ink supply channel to the ink outlet gap. In this way, a relatively large volume of ink is accumulated in the ink cushion space, which due to the narrowing of the ink cushion space in the direction of the ink outlet gap, which acts more reliably there, is reliably conveyed to the ink outlet gap and thus to the pen.
  • the ink cushion space can taper in a wedge shape in the axial central plane of the ink guide that runs through the center of the groove.
  • the provision of the ink cushion space and the ink outlet gap according to the invention ensures reliable ink supply to the nib even under difficult writing conditions, so that the ink line according to the invention is suitable for nibs with a smaller line width as well as for nibs with a larger line width.
  • the ink supply channel or the ink supply channels are formed on the underside of the insert.
  • the ink supply channel or channels of which are dimensioned so that they have the sufficient Convey the amount of ink to the front end of the ink guide, and which is shaped so that it forms, together with the main body, an ink cushion space and an ink outlet gap with dimensions suitable for the respective operating case.
  • transverse channels can be provided on its underside for connection to the radial ink receiving chambers.
  • positioning projections can be formed on the side walls of the insert part.
  • the ink guide shown in Figures 1 to 13 consists of a main body 1 and an insert 10. Both components are usually made of plastic and can be manufactured by injection molding.
  • the main body shown in detail in FIGS. 4 to 6 can be firmly connected to a fountain pen with its rear end (right end in FIGS. 4 and 5). In a central region, it has ink receiving chambers 2 arranged radially in the usual way.
  • An axially extending groove 4 extends from the rear end of the main body and has an essentially rectangular cross section and ends at a surface 33 at the front end. In the bottom of the groove 4 there is an air channel 7 at the rear end, which in the assembled state is connected to the ink supply space and at the front end of which a conventional pressure control path 6 begins.
  • An air duct 5 extends axially forwards from this pressure control section 6 and is connected to the foremost ink receiving chamber 3 via a transverse incision (FIG. 6).
  • the base area lying in front of the air inlet duct 3 and no longer traversed by the air duct extends 31 of the groove 4 into an obliquely upwardly extending surface 32 which ends at the surface 33, while the side walls of the groove 4 form wall sections 34 and 35 which converge towards the front from the transition to the surface 32.
  • the boundary surface 33 of the groove lies at a short distance behind the front end surface 9 of the main body 1.
  • the insert 10 is shaped so that it fits into the groove 4 and extends from the rear end to just before the wall 33.
  • the insert 10 has on its underside two capillary-shaped ink supply channels 11, 12 which start from the rear end of the insert 10 and end shortly before its front end.
  • Cross channels 17 are also formed on the underside of the insert part 1 (FIGS. 9 and 12), which in the assembled state connect the air channel 5 formed in the main body 1 to the radial ink receiving chambers 2.
  • the insert part 10 in the area behind the shoulder 22 (FIGS. 1 and 9) is curved in the circumferential direction corresponding to the main body 1 receiving the insert part 10, while the area 23 which forms the spring support surface and lies in front of the shoulder 22 (FIGS. 1 and 9) has a larger radius of curvature, which corresponds to the inner radius R (FIG. 3) of the nib to be attached, while the surfaces of the main body 1 adjoining in the circumferential direction have a smaller radius of curvature.
  • the lower surface of the insert part 10 runs in the front area as a surface section 20 obliquely up to the front end surface 21 of the insert part 10. Furthermore, the Side walls in the front end region converge as side wall sections 18 and 19 to the front end surface 21. Shortly before the transition to the side wall sections 18 and 19, positioning projections 13 and 14 are formed on the side walls, which engage when the insert part 10 is inserted into the groove 4 of the main body 1 stand with the air inlet duct 3 ( Figure 1). A further positioning within the groove 4 takes place by means of the projections 16 and 15 provided on the side wall sections 18 and 19, which come to bear against the side wall sections 34 and 35 of the groove 4 in the main body 1 (FIG. 13).
  • an air channel 5 is provided in a known manner between these two components on the one hand, which is connected to the radial ink receiving chambers 2 via transverse grooves 17, and on the other hand capillary ink supply channels 11, 12 are formed, which the Ensure ink is supplied from the fountain pen ink reservoir to the front end of the ink guide.
  • capillary ink supply channels 11 and 12 are formed in the insert part 10.
  • the capillary ink supply channels 11 and 12 run in a straight line over their entire longitudinal extent and, as can be seen particularly in FIG. 12, open into an ink cushion space 30 at their front end.
  • This ink cushion space becomes on its underside from the wall section 31 of the groove 4 and the rising wall section 32 in the main body 1 and on its upper side delimited by the inclined wall section 20 on the underside of the insert part 10.
  • the limitation is made at the front end by the wall 33 and on the sides by the wall section te 41 and 42 of the main body 1.
  • the ink cushion space 30 tapers forwardly from the mouth region of the ink supply channels 11 and 12.
  • the front end surface 21 of the insert part 10 runs at a small distance from the surface 33 of the main body 33, and the side wall sections 18 and 19 of the insert part 10 run at a corresponding distance from the side wall sections 41 and 42 of the main body 1, so that between these walls a capillary, to the spring receiving surface open ink outlet gap is formed, which is symmetrical to the axial central plane 25 of the ink guide and is substantially U-shaped ( Figure 13), the base 40 of the U being transverse to the plane 25 and the legs 41, 42 of the U diverge backward from the base 40.
  • FIG. 14 While an essentially U-shaped ink outlet gap is shown in FIG. 14, the same has the same in the rest How the ink guide according to Figures 1 to 13 constructed ink guide according to Figure 14 has a V-shaped ink outlet gap with two legs 41 'and 42', which are symmetrical on both sides of the axial central plane.
  • This ink outlet gap 44 ⁇ is arc-shaped, approximately circular-arc-shaped and ends at the rear at points 45 ⁇ and 46 ⁇ , which are arranged significantly further outwards and behind its most forward central region.
