Definitions

  • the invention relates to an ink conductor for writing elements on writing instruments with a lamella-like compensation system with grooves separated by webs for ventilation.
  • Ink conductors for writing elements with compensation systems are used worldwide, both in fountain pens with nibs and in writing instruments with other writing elements, e.g. B. with fiber or ball point. Almost all of them have in common the well-responding system to fluctuations in temperature and air pressure due to the easy filling of the molded collecting chambers.
  • the chambers are usually aerated and vented through an air duct opposite the ink supplying capillary duct. Once the chambers are filled with ink, the system is no longer resistant to shaking and ink residue can therefore escape from the air duct. This disadvantage is particularly uncomfortable for the user when the writing instrument is already filled and mailed for shipment. Ink residues then collect in the sealing cap and initially flood its sealing area. When the cap is removed, the writing fluid often escapes from the cap and the user becomes dirty.
  • the document EP-A-0 091 610 describes an ink conductor for fountain pens with capillary ink chambers arranged on both sides of the ink conductor core in the interior of the holder shaft front part and with a ventilation channel connecting the ink chambers with the outside air.
  • the collecting chambers are arranged in the longitudinal direction of the writing instrument, so that the writing fluid can only poorly penetrate into the collecting chambers.
  • the document DE-U-78 06 264 relates to an ink regulator for writing utensils for holding excess ink with a transverse lamella system.
  • the object of the invention is to get them by shaking or shipping by appropriate arrangement of the ventilation grooves on the compensation system even if this z. B. is largely flooded by air shipping.
  • the collecting chamber halves arranged on a tubular body to the central air groove have two parallel ventilation grooves which are sealed by webs, the ventilation grooves are closed at the front by a flange and at the rear via a transverse groove with a central air groove are connected, the transverse groove being connected to a controlled system, a capillary gap and an air groove and a writing element receptacle being fixed in a sealing sleeve by a frictional connection in a receptacle sleeve.
  • the lamellar body of the compensation system is divided into two halves, each of which is traversed by an air groove and which are connected in the rear region of the system to a central air groove by a transverse groove, which are connected to the ink reservoir by a control path with an air groove.
  • two collecting chamber halves 3b of the body 3 of the compensation system are each penetrated by an air groove 3f which is sealed in the front area by a flange 3m and by a web 3s on a longitudinal rib 3i on a longitudinal rib 3i on an longitudinal air groove 3f are vented and which are connected in the rear region of the body 3 by a transverse segment-shaped groove 3k arranged under a capillary gap 3a to the central air groove 3e located in the middle of the lower longitudinal rib 3i of the body 3.
  • the groove 3k is connected to an ink reservoir 6 via a control path 3r and an air groove 3d.
  • the writing instrument contains the writing element 1, which is held in a receiving bore 2a of the writing element holder 2 by frictional engagement.
  • the conical bore 2b serves to receive the rear end of the writing element 1, while 2g denotes a front annular air groove.
  • the writing element holder 2 has an air shaft 2h.
  • the push-on pin 2k carries a flange 2i.
  • a capillary longitudinal gap 2c is formed, which creates the connection to a capillary annular gap 2d, which is formed by a shoulder 21 on a plug-in pin 2k of the writing element receptacle 2 and the front end of a receiving bore 3n of the lamellar body 3.
  • a longitudinal rib 3h is formed on a tube piece 3g, in which the capillary longitudinal gap 3a is attached, which creates the connection from the capillary annular gap 2d to the ink reservoir 6.
  • Lamellas 3c of circular cross-section are formed on the pipe section 3g, and are circumferentially sealed by a receiving sleeve 4.
  • the receiving sleeve carries a bead 4a at its rear end, while with 5 a support ring is designated.
  • the two collecting chamber halves 3b are located between the lamellae 3c and are connected to the capillary longitudinal gap 3a by two capillary transverse gaps 31.
  • the lower longitudinal rib 3i is formed on the tube piece 3g with the webs 3s, which form the air groove 3e in its center, which opens into the transverse groove 3k at its rear end.
  • the ventilation grooves 3f are formed on the rib 3i in the area of the lamellae, which serve for ventilation of the two halves of the collecting chamber 3b.
  • the transverse groove 3k is connected via the controlled system 3r to the capillary gap 3a and to the air groove 3d.
  • the ink removed when using the writing instrument with the writing element 1 flows from the ink reservoir 6 via the capillary longitudinal gap 3a attached to the body 3 in the upper longitudinal rib 3h into the capillary annular gap 2d and then reaches the rear end of the writing element 1 and via the capillary longitudinal gap 2c supplies this with the necessary ink.
  • the resulting excess pressure in the ink reservoir 6 is quickly and reliably reduced by the inflow of ink into the two collecting chamber halves 3b via the capillary transverse gaps 31, so that no drop formation can occur at the tip of the writing element.
  • the collecting chambers closest to the writing side of a known writing instrument first fill with writing fluid. It is therefore also the case that if the halves of the collecting chamber are only ventilated and ventilated with a common air groove underneath, the front region of the air groove is flooded with ink, without the absorption capacity of the lamella system being able to be fully utilized. An air groove filled with ink is no longer resistant to shaking or shipping.
  • the two ventilation grooves 3f running parallel to the lower middle air groove 3e are provided according to the invention, which, when the collecting chamber halves 3b are filled with ink, these after the rear end of the body 3 vent and allow the ink to flow into all of the collecting chambers 3b without the central air groove 3e being accidentally filled with ink. Only when both collecting chamber halves 3b are filled up to the rear connecting transverse groove 3k can the ink penetrate into the middle air groove 3e.
  • baffle walls which are located in the front area of the writing element receptacle 2 by appropriate design of air grooves 2e, 2f, the resistance to shaking can also be improved even when the middle air groove 3e is filled, as can be seen from the drawing.
  • the controlled system 3r opens and allows air to flow into the reservoir 6 to such an extent that the pressure equalization from the reservoir 6 to the ambient air is constantly produced and ink is thus supplied to the writing element 1 in the required amount.
  • the ink closes the control path 3r and thus prevents the formation of drops on the writing element 1.
