Definitions

  • the invention relates to a writing instrument with a front end of a housing part held writing tip, a holder shaft which can be connected to the housing part and a Writing fluid storage space in the form of a replaceable one Cartridge with a receiving section provided in or on the housing part up to a writing position defined by the stop is connectable so that one with the writing tip related liquid conduit into the interior the cartridge extends, and which can be moved to a reserve position in which it is connected to the receiving section, however, the liquid guide tube is less far into the interior the cartridge protrudes than in the writing position, the Reserve position due to relocatable or elastically deformable Latching or sling gear is defined.
  • the cartridge has a front neck area that is an external thread carries, in a receiving portion having an internal thread the housing part of the writing instrument is screwed in, through which a liquid conduit extends coaxially, the protrudes into the interior when the cartridge is fully screwed in.
  • the cartridge can so far in this writing position be spelled blank that the liquid level in it in substantially equal to the length of the section of the liquid guide tube that protrudes into the interior of the cartridge.
  • the cartridge pivots User the free end of the leaf spring-like element somewhat outwards, so that its hook section from the ring shoulder the cartridge is released and he can then remove the cartridge completely Unscrew from the receiving section to secure it against a replace new, filled cartridges.
  • a writing instrument is also already known (DE-GM 1 832 702), that can be equipped with a standard euro cartridge, so that a liquid guide tube extends into the interior thereof.
  • the cartridge is placed in a kind of cartridge holder carriage used the forward against the force of a coil spring is shifted to bring the cartridge into its writing position.
  • the front face of a cap part from the rear in the holder shaft is screwed in completely screwed position the writing position of the cartridge effecting front position of the cartridge receiving carriage defined.
  • the cap part is up to one by a stop screwed out defined position from the holder shaft, so the pressure of the coil spring causes a corresponding shift of the cartridge carriage to the rear, causing the cartridge to slide in reaches a reserve position in which the liquid guide tube protrudes less far into the interior of the cartridge than in the Writing position.
  • a writing instrument is the beginning mentioned type designed according to the invention by a cartridge holding cartridge carriage, which is axially limited is displaceably inserted in the receiving section and at least one with a section through an opening in the Has wall of the receiving portion extending spring element, whose partial area is in the writing position and in the reserve position behind a radially inward ring shoulder surface extends in the inner wall of the holder shaft, which on the receiving section is screwed on and when unscrewing the cartridge receiving carriage by engagement of its spring element with the ring shoulder surface shifted axially backwards, so that the spring element radially inward and out of engagement with the annular shoulder surface is moved, and the interacting Latching or slinging means on the inner wall of the holder shaft and formed on the outer wall of the receiving portion are.
  • the holder shaft is missing in this mounting process, also missing the areas of the holder shaft that are intended to To define the reserve position of the cartridge, namely the ring shoulder area in the inner wall of the holder shaft and the likewise on the inner wall of the holder shaft existing or Slings.
  • the holder shaft is on the outer wall of the receiving section screwed on, so that the portion of the spring element behind the ring shoulder surface in the inner wall of the holder shaft snaps.
  • the cartridge receiving carriage is preferably tubular and can attach a ring shoulder to the front end have a transition surface of the cartridge, as in Euro cartridges between the mouthpiece and main section is common.
  • the at least one spring element can essentially consist of one axially and forwardly extending spring arm exist the free end of the section for engaging with the Ring shoulder surface is formed in the holder shaft.
  • two diametrically opposite one another opposing spring elements are present to ensure an even Support of the cartridge holder carriage in the radial direction to get and thus tilting within the receiving section to avoid.
  • the locking or stop means can consist of at least one projection and two between them a well for the Projection-forming projections exist, advantageously two diametrically opposite projections the corresponding recess is available.
  • a projection is through an annular rib forming the annular shoulder surface.
  • the holder shaft can be a receiving space for holding an additional cartridge, which in the writing position of the connected to the receiving section Cartridge and when fully screwed onto the receiving section Support shaft supported at the rear end of the Recording space rests on the rear face of this cartridge.
  • the writing instrument shown has a housing part 1, from which front end is usually part of the used Ink guide body 2 extends on which the nib 3 is placed is that with its rear end area jammed in the housing part 1 is held. At the rear end of the housing part 1 there is a liquid guide tube 8 which is open to the rear and which in not shown, but more common for cartridge fountain pens Way with the ink guide body 2 is connected.
  • a tubular receiving section surrounding this 4 trained which is open to the rear and in his rear area has an external thread 5, while before External thread 5 two diametrically opposite, elongated Through openings are available.
  • this recording section 4 is a tubular cartridge receiving carriage 20 inserted, which has a narrowed neck area at its front end 21, which has a transition surface 22 with the main body of the cartridge receiving carriage 20 is connected.
  • Leaf spring-like arms 23 are formed in the wall of the main body, the protruding at their free, front end form thickened engagement areas 24, which are in the receiving portion 4 inserted cartridge carriage into the elongate openings 7 of the receiving portion 4 extend ( Figure 8) or in relation to the position according to Figure 8 further Cartridge receiving carriage displaced in the front in the receiving section 4 20 through the openings 7 radially outwards over the circumference of the receiving section 4 protrude ( Figures 1 and 3).
  • the writing instrument When the writing instrument is ready for operation, it is in the cartridge holder carriage 20 a conventional ink cartridge 25, such as one so-called euro cartridge inserted, which at the front end Mouthpiece 26 forms that over a conical surface with the Main body of the cartridge 25 is connected.
  • the mouthpiece 26 extends through a narrowed front region 21 of the cartridge receiving carriage 20, and the conical surface 27 rests a corresponding transition surface of the cartridge receiving carriage 20 on.
  • the user unscrews the holder shaft 1 even further from the external thread 5 of the receiving section 4, whereby, as can be seen in FIGS. 5 and 6, the leaf spring-like arms 23 due to increasing engagement of their radially outward curved areas with the rear edge of the Openings 7 are gradually bent elastically inwards until the outer end portions radially inward from the area of the Ring rib 15 in the additional tube 13 of the holder shaft 10 came out are.
  • the Holder shaft 10 are completely unscrewed during the Cartridge carriage 20 and correspondingly the cartridge 25 in remain in the position, as can be seen in Figure 7, in the the mouthpiece 26 of the cartridge 25 just engages with the Liquid guide tube 8 is.
  • the user can remove the cartridge 25 from the position shown in FIG pull it off and out of the cartridge carriage 20 (FIG. 8) and replace with a new filled cartridge.
  • this new cartridge When inserting this new cartridge, it first reaches the position shown in the figure 7 and is then moved forward to the liquid guide tube 8 pushed on until the face of the mouthpiece the cartridge to rest on the surrounding the liquid guide tube 8 Annular surface of the housing part 1 comes, the liquid guide tube 8 so the cartridge has opened on the one hand and on the other hand in their interior corresponding to that described above Wrong position protrudes.
