Abstract

A writing instrument, in particular a fiber pen, marker pen or liner with two optionally usable different writing tips (7, 9) is provided, which are arranged at the same end of the writing instrument and nested one inside the other and can thus be fed together from a writing material store (4).

Description

  • The invention relates to a writing instrument, in particular a fiber pen, marker pen or liner or the like with two different writing tips which can be used optionally and which can be fed from a common writing material store.
  • In writing instruments of this type, it is known to enable different writing thicknesses by means of a specific shape of the writing tip protruding from the device body, in that differently shaped areas of the writing tip are brought into contact with the base by different positions of the writing tip relative to the background. On the one hand, this handling is cumbersome and unsatisfactory because it requires special skill to select the position of the writing instrument required for the desired line width. In addition, the various areas of the writing tip, in particular those for finer lines, are quickly worn or destroyed by the writing pressure, in particular in connection with a rough base, so that the writing instrument can only be used for the thicker lines.
  • A writing instrument is also known in which a writing tip is assigned to the two opposite ends of the device body, the two writing tips differing in different line widths. Here, too, the handling is cumbersome, since the writing instrument has to be rotated constantly when the stroke width changes. In addition, there is the risk of hands or clothes being soiled by the backward-pointing writing tip that is not in use. Finally, it has been found that the supply of the writing nibs of different thicknesses lying at the opposite ends of the writing instrument from a common writing material store (tampon) is problematic and often only the writing nib of larger diameter is sufficiently supplied with writing material after a short time.
  • It is an object of the invention to develop a writing instrument with the features of the preamble of claim 1 in such a way that the disadvantages shown are reliably avoided, simpler handling is made possible, a Ver There is practically no fear of changing the line widths even after prolonged use, and a reliable supply of both writing tips from the common writing material store is guaranteed until the writing material supply is used up.
  • This object is achieved by the teaching of claim 1.
  • In this embodiment, the different line widths are not guaranteed by the shape of a writing tip, but by two separate writing tips, each of which is set to the line widths. This means that the line width practically does not change even with frequent use of one or both writing tips. Handling is extremely simple, since both writing tips are provided at the same end of the writing instrument. The nesting of the two nibs largely protects them from drying out on the one hand, while on the other hand a reliable supply of both nibs from the writing material storage (tampon) is guaranteed until the writing material is used up.
  • Another advantage is that the two writing nibs can be made of different materials, the writing nib of smaller diameter generally having greater hardness. As a result, the smaller-diameter writing tip nested in the writing tip with a larger diameter can give the larger writing tip a better hold and a certain protection against premature wear and thus contribute to a longer service life of the larger writing tip.
  • This is achieved particularly advantageously if the arrangement is carried out according to the teaching of claim 2 and / or claim 3. In the latter case, the writing tip of smaller diameter forms part of the contact area between the larger writing tip and the writing pad.
  • The writing tip of larger diameter can be supplied from the writing material memory via the writing tip of smaller diameter, since both are in extensive mutual sliding contact due to the nesting, via which the writing material can reliably pass through the capillary action into the writing tip of larger diameter.
  • Alternatively or additionally, the training can also be carried out according to the teaching of claim 5, so that both writing tips are also supplied directly from the tampon.
  • The relative shift of the two writing tips can be realized in different ways.
  • The invention is explained below with reference to schematic drawings of two exemplary embodiments.
  • Show it:
    • Figure 1 in side view, partially axially cut a writing instrument according to the invention;
    • FIG. 2 shows a longitudinal section containing the axis of the writing instrument in a plane perpendicular to the representation plane according to FIG. 1;
    • Figures 3 and 4 in side view two interacting parts of the writing instrument, namely in Figure 3 in the writing position for the large diameter writing tip and in Figure 4 in the writing position for the small writing tip;
    • Figure 5 in side view and in detail a modified embodiment of the new writing instrument;
    • FIG. 6 shows a detail from FIG. 5 on a larger scale;
    • Figure 7 in a representation similar to Figure 2, a second embodiment of the new writing instrument;
    • Figure 8 is a side view of the associated insert;
    • Figure 9 shows the insert in front view
    • Fig.10 The insert in side view, but rotated by 90 ° compared to Figure 8.
  • The writing instrument 1 according to FIGS. 1 to 4 consists of a writing instrument holder or body 2, in which a writing material storage or tampon 4 is fixedly arranged. The open end of the writing instrument body 2 can be closed by a push-on cap 3, the open end of which is formed by elastically deflectable webs separated by slots, so that the cap 3 can also be pushed onto the thicker, closed end of the writing instrument body 2.
  • In the open end of the writing instrument body 2, a holding bush 5 is firmly inserted, possibly also glued in. The bottom of the socket 5 is formed by a crossbar 5a. The outer end of the writing material storage 4 has a transverse recess 16, in which the transverse web 5a of the holding bush 5 is received. The storage part 4 can thus be pre-assembled together with the holding bush 5 in the writing instrument body 2.
  • In the crosspiece 5a of the holding bush 5, the inner end of an elongated writing tip 9 of small diameter is inserted and, as shown at 10, fastened. The inner end of the writing tip 9 projects sufficiently far into the writing material storage 4 via the crosspiece 5a in order to allow the writing material to pass reliably into the writing tip 9 under capillary action if necessary.
  • The writing tip 9 of smaller diameter is accommodated over a large part of its length with a sliding fit in a longitudinal bore 8 of a writing pen 7 of larger diameter, so that both writing tips are nested concentrically one inside the other and promote the transition of the writing material over the entire length of the bore 8 Are in contact with each other.
  • The writing tip 7 of larger diameter is received by a holding bush 6, which is received in front of the front open end of the writing instrument body 2 and engages with a plurality of extensions 6a so that it can rotate in the open end of the holding bush 5. The extensions 6a have radially projecting lugs or pins 14 which snap into the guide and control grooves 13 of the holding bush 5 when inserted. The pins can also be provided on the holding bush 5 and the slots 13 on the holding sleeve 6. The slots are provided helically opposite each other with a slight pitch, so that they each cause a self-locking lock between the holding bush and the holding sleeve in the end positions.
  • By relative rotation of the holding sleeve 6 with respect to the holding bush 5, the holding sleeve 6 is displaced outward or in again by an axial displacement path 15 depending on the length and the slope of the slots 13 with respect to the holding bush 5. The writing tip 7 of larger diameter takes part in this relative movement compared to the writing tip 9 of smaller diameter. In the outwardly pushed position of the holding bushing 6 (FIG. 3), the contact surface of the writing tip 7 with a writing pad lies with the end or the contact surface of the writing tip 9 of smaller diameter, so that in this writing position (FIG. 3) there is a continuous, uniform contact surface 7a Writing pad is available. Since, in general, the writing tip 9 is made of harder or stronger material than the writing tip 7, the writing tip 9 also contributes in this writing position to stabilizing the position of the writing tip 7 and to reducing the wear on its contact surface 7a, i.e. the service life of the To enlarge contact area 7a. By relatively pushing back the holding sleeve 6 with respect to the holding bush 5, the writing tip 7 is also withdrawn with respect to the writing tip 9, whereby the writing tip 9 is exposed (FIG. 4), so that writing can now be carried out with fine line width without problems and in the normal position of the writing instrument.
  • In the modified exemplary embodiment according to FIGS. 5 and 6, the slots 30 of the slot connection 30, 31 are arranged parallel to the axis of the writing instrument. In the example shown, the holding sleeve is denoted by 26, the holding bushing by 25, the extensions of the holding sleeve by 38, 29 and the pin 31 which engages in the slot 30.
  • The end positions of the slot 30 are assigned detents 32 and 33 which secure the writing tips in the end positions for writing use.
  • The writing instrument 41 according to FIGS. 7 to 10 consists of a writing instrument body 42, in which a first writing material store 44a and a second storage 44b for a different writing material are arranged concentrically to one another. The two writing material stores are separated from one another by a tubular separating body 50. The open end of the writing instrument body 42 can be closed by a push-on cap 43, as has already been described in the first exemplary embodiment.
  • An insert 51 is firmly inserted into the open end of the writing instrument body 42. This insert body is shown in Figures 8 to 10 in detail and on a larger scale. It consists of an outer sleeve which is firmly inserted into the writing instrument body 42 and which has oblique control slots 52 in its outwardly pointing end region. Arranged in the interior of the insert part 51 is a central part 56 which is in the form of a knife and projects from a transverse wall. This has a hollow mouthpiece 53, on which the tubular separating body 50 is sealingly and firmly placed. The writing tip 48 of smaller diameter protrudes through its bore 54 and engages in the inner writing material storage 44a and is in constant intimate contact with this writing material storage. The writing tip 48 can have an outer writing tip part 49. This writing tip 48, 49 is received by a separating sleeve 60 over most of its length. The inner end of this separating sleeve is firmly and sealingly received in a corresponding bore in part 56. In this way, the inside writing system is reliably and completely sealed from the outside and still allows a reliable writing flow from the memory 44b to the outside writing tip 49.
  • As can be seen from the figures, the outer writing material storage 44a overlaps the inner section 56 of the insert part 51, which engages deeply in the outer writing material storage 44a. In the area of the insert part 51, this writing material storage has an inner bore in which the outer writing tip 47 of larger diameter can slide in the axial direction to a limited extent, while it is in constant exchange with the writing material storage 44a. The outer writing tip 47 is supported by a holding bush 46 which, with a plurality of axially inwardly projecting projections 46a, engages in the open end of the insert part 51 in a rotationally and axially displaceable manner. The extensions 46a have radially projecting pins 52a which snap into the control grooves 52 of the insert part 51 when inserted. By turning the holding bush 46, it moves in the axial direction with the outer writing tip 47 of larger diameter. Compared to the fixed inner writing tip 46, it can thus be pushed axially into a writing position or pushed back into a non-use position relative to the latter.
