  • the invention relates to writing, drawing, painting or similar devices with an interchangeable cartridge which can be fixed in the barrel for a medium to be applied with the device.
  • medium is understood to mean both a liquid and a paste, i.e. the means commonly used for writing, drawing, painting, marking, etc. Since the composition of this medium is irrelevant, it will not be discussed in more detail.
  • the shaft generally consists of several, essentially coaxial parts that can be fixed to one another, for example, by a screw connection.
  • a part must be removed, for example unscrewed.
  • the cartridge can then be removed and a new cartridge inserted in the barrel.
  • This ax of action has several shortcomings. On the one hand, replacing the cartridge is relatively cumbersome, which is especially true if the two of them Shaft parts are fixed to each other by means of a screw connection.
  • the invention is therefore based on the object of designing a device of the type mentioned at the outset in such a way that the cartridge can be replaced quickly and easily with a simple barrel and cartridge design.
  • the cartridge can be fixed directly to the shaft by means of a snap-lock connection.
  • the manufacturing costs of a device can be reduced the invention compared to the previously known devices, in which several shaft parts were required, significantly lower.
  • the proposal of the invention is particularly favorable when the cartridge or the associated device have a correspondingly large diameter, since in such a case, for example, the production of an injection-molded thread would encounter considerable difficulties with sufficient accuracy. According to the invention it is therefore practically possible for the first time to equip devices with cartridges of very large capacity, for example marking devices, with exchangeable cartridges.
  • the snap-lock connection can be produced in a simple manner in that the shaft has at least one undercut on the inside and the cartridge has at least one projection which engages behind the undercut in the snap-in position and which is resiliently movable inwards.
  • the design becomes particularly simple when the at least one projection is integrally formed on the wall of the cartridge and this can be pressed resiliently inwards at least in the region of the projection.
  • Such a training poses no difficulties, particularly for cartridges of large diameter, since they can be made from suitable plastic and a tampon, for example, which is present inside, can always be sufficiently compressed.
  • the wall of the cartridge will expediently consist of an elastically deformable material, preferably plastic.
  • the shaft and cartridge are provided with guide elements interacting in the locking position.
  • the shaft can advantageously be attached have at its rear end a receptacle encompassing the rear end of the cartridge, preferably an opening. In the presence of such an opening, the rear end of the cartridge could be provided with a marking identifying the content, which is then also visible from the rear end of the shaft when the cartridge is inserted.
  • the shaft in the region of its front end has at least one longitudinal groove, preferably formed by a slot, into which a bar provided on the outside of the wall of the cartridge can be inserted. If the longitudinal groove is a slot, the strip is also. visible on the cartridge on the side of the writing instrument. It could therefore also be used as an essence mark for the cartridge.
  • the bar is designed as a pressure element for pressing in the wall of the cartridge in the region of the projection.
  • the bar is appropriately chosen so large that it slightly overhangs the outer surface of the shaft of the device in the locked position. However, it is also sufficient if the outer surface of the bar is flush with the outside of the shaft and only the bar has the corresponding width.
  • the shaft to have at least two undercuts and the cartridge to have at least two projections which are arranged at approximately equal angular distances from one another in order to achieve a symmetrical mounting of the cartridge in the shaft in this way.
  • two undercuts and protrusions are sufficient.
  • Two undercuts and Protrusions will be provided in particular when the device is flattened, in which case these should be arranged in the region of the shorter sides, not the flattened shafts.
  • Figure 1 partially in section the marking device
  • FIG. 2 shows in section the area of the snap-in connection marked with A in FIG. 1 between the cartridge and the shaft when the cartridge and
  • Figure 3 shows a section corresponding to Figure 2 during the
  • the marking device shown in Figure 1 has a cartridge 1 with a relatively large volume, which almost completely fills the interior 2 of the shaft 3. In this way, a comparatively good guidance of the cartridge 1 inside the shaft 3 is already achieved without special aids.
  • the application tip 4 can be covered by means of a cover cap (not shown in the drawing), in which connection it should be pointed out that the shaft per se, as can be seen from FIG. 3, extends to the front edge 5 which appears as the shoulder of the cartridge 1 in FIG , to which a possibly attached cap connects.
  • the shaft 3 is open at its front edge 5 over the entire cross section and is closed by the correspondingly shaped front end of the cartridge 1 when it is in the latching position (FIGS. 1, 2).
  • a snap-in connection serves to fix the cartridge 1 in the shaft 3, which can be seen particularly clearly from FIGS. 2 and 3.
  • the shaft 3 has an undercut 6 on the inside, which forms a shoulder 7.
  • a projection 8 on the outer wall of the cartridge 1, which also has a shoulder 9 cooperates in the latched position.
  • the shoulders 7 of the undercut 6 and 9 of the projection 8 lie against one another in the manner shown in FIG. 2.
  • FIGS. 2 and 3 clearly show that the projection 8 - or, in the exemplary embodiment shown, the two projections 8 - are molded directly onto the wall 10 of the cartridge 1.
  • the cartridge 1 consists of an elastically deformable material. In this way, by slightly squeezing the cartridge 1, it is possible to release the snap connection, i.e. to move the projections 8 from the locking position shown in FIG. 2 into the position of FIG. 3, where the cartridge 1 can then be removed from the shaft 3.
  • the shaft 3 Near its front end, the shaft 3 has longitudinal slots 11, in the exemplary embodiment shown there are two opposite longitudinal slots into which corresponding, radially projecting strips 12 of the cartridge 1 protrude from the front edge 5 can be inserted here.
  • These strips 12 serve, on the one hand, as guide elements for the cartridge 1 with respect to the shaft 3, whereby they can prevent rotation of the cartridge 1 with respect to the shaft 3, for example, when the shaft 3 and cartridge 1 are round.
  • the strips 12 can be used as pressure elements, for which purpose they are so wide or so high that in the region of the troughs 13 sufficient pressure can be exerted to release the snap connection between the cartridge 1 and the shaft 3, ie the wall 10 of the cartridge 1 accordingly can be bent far inwards.
  • the height of the strips 12 is selected in accordance with the thickness of the wall of the shaft 3.
  • the strips 12 must have a sufficient width. If only comparatively narrow strips 12 are provided, their thickness must be chosen somewhat larger so that they protrude at least to a small extent over the outside of the shaft 3, camouflaging a sufficiently wide movement of the strips 12 inwards and thus allowing the latching connection to be released .
  • the cartridge 1 largely fills the interior of the shaft 3. However, there is still a certain space between the wall of the shaft 3 and the outside of the cartridge 1, which is necessary to easily insert the cartridge 1 into the shaft. 3 to be able to insert. This would mean that the cartridge might move slightly sideways.
  • the rear end of the cartridge 1 has a shoulder 14 which engages in a suitable opening 15 on the end face 16 of the shaft 3 as soon as the cartridge 1 is in the latched position.
  • the presence of the strips 12 or the attachment 14 on the cartridge 1 gives the possibility of making corresponding markings with respect to the contents of the cartridge 1, which are visible even when the device is closed. For this purpose, only the attachment 14 and the strips 12 have to be marked accordingly when the cartridge 1 is manufactured.
  • the principle of the invention can not only be used in writing instruments with comparatively thick cartridges, although it is particularly favorable there because of the possible movement of the cartridge wall and its use in connection with the latching. It would of course also be possible to provide a corresponding latching connection between the cartridge and the shaft even in the case of devices of a different design, in which case special latching elements would then have to be provided on the cartridge.
