Definitions

  • the invention relates to a writing instrument with a sleeve-shaped housing and a writing element arranged in this housing, which can be displaced between a ready-to-write position releasing the tip section of the writing element used for writing and a storage position retracted into the housing, the housing section adjacent to the tip section of the writing element consisting of segments , which are radially spread apart in the ready-to-write position and abut one another in the storage position and form a closure part for the tip, the housing consisting of an outer sleeve and an inner sleeve arranged essentially within the outer sleeve and displaceable in the axial direction relative to the inner sleeve, and which form the closure part of the housing
  • Segments are mounted on the inner sleeve, are radially outward under tension and are partially outside the outer sleeve, where they have a larger outer diameter than the clear width of the tip-side end of the outer sleeve, and wherein the inner sleeve over one on the outer Sleeve supporting spring is biased towards the storage position and by means of an actuator supply element against the pressure of the spring is axially displaceable, according to patent no. (application P 33 41 759.8).
  • the invention has for its object to improve such a writing instrument so that its manufacture and operation is further facilitated.
  • the actuating element has a switching mechanism, that the spring biasing the writing element against the housing is supported on the inner sleeve, that the switching mechanism acts on the outer sleeve, that the restoring force of the writing element biasing against the inner sleeve Spring is smaller than that of the spring that biases the inner sleeve against the outer sleeve, and that the actuating element consists of two axially displaceable elements, of which the first acts on the intermediate sleeve and the second acts on the writing element, carries the switching mechanism and is operated by the first element.
  • the two elements of the actuating element have an essentially complementary shape and together essentially form the shape of a cylinder.
  • a further improvement of the writing instrument according to the invention is achieved in that the segments have a recess on their inside in the area comprising the tip section, in each of which correspondingly shaped elastic sealing shells are fastened, which come into abutment in the storage position and hermetically surround the tip section form a tight chamber. With this configuration, a hermetic sealing chamber can be created around the writing tip with the simplest of means when the writing instrument is in the storage position.
  • the segments are preferably mounted on the inner sleeve via tapered web areas.
  • Figure 1 - 1 b longitudinal sections through the embodiment of the writing instrument in the rest, switching and writing phase
  • FIGS. 1 to 1 b shows an enlarged top view of one of the two half-shell intermediate sleeves 104 of the writing instrument from FIGS. 1 to 1 b,
  • FIG. 3 shows an enlarged top view of a sealing shell 99 of the writing instrument
  • FIG. 5 shows an enlarged cross section through the closed closure tip of the writing instrument from FIG. 1,
  • FIG. 6 shows a further enlarged cross section through the closed closure tip of the writing instrument from FIG. 1
  • Fig. 7 is an enlarged cross section through the opened closure tip of the writing instrument
  • Fig. 8 is an enlarged cross section through the push button 101 of the writing instrument
  • Fig. 9 shows another enlarged cross section through the push button of the writing instrument
  • FIGS. 1-10 shows an enlarged cross section through the rear switching area of the writing instrument from FIG. 1
  • the exemplary embodiment of the writing instrument shown in FIGS. 1-10 has a preferably two-part sleeve-shaped housing 1 and 31, and an intermediate sleeve 104 arranged therein, which preferably consists of two half-shells welded together at the rear.
  • the half shells are each provided on their front side with a bending web 102 and a pressure shell 109 located thereon.
  • the pressure shell 109 preferably serves as a support for an elastic sealing shell 99 which is firmly connected to it.
  • the writing tip 26 of the writing element 2 is hermetically sealed during the closed state (FIG. 1) and in such a way that the evaporation pressure of all known writing and solvents is sealed absolutely securely.
  • the closure pressure which is brought about by a very strong spring 9, is also so great that any writing fluid which may leak out in the closed sealing shells can under no circumstances penetrate capillary outwards.
  • a partially partial-shell push-button element 101 the partial-shell regions 105 and 106 (FIGS. 1, 4, 8, 9 and 10) of which extend to the rear end of the intermediate sleeve 104 and can act on it (FIG. 1 ).
  • a switching part 108 In the area that is not filled in at the rear by the push-button element 101, there is also a switching part 108, with a circuit 3 ′ engaging on the housing 31, which can act on the writing element 2 and which can be carried by the push-button element 101.
  • the closure 109, 102, 99 can be used to achieve a symmetrical shape be in three or more parts during the writing state. Furthermore, several grooves and grooves can advantageously be provided on the pressure shells 109 for fastening the sealing shells 99, which enable the sealing materials 99 to be clamped or snapped into place on the pressure shells 109 without using adhesive, vulcanizing or other methods.
  • the sealing area to the actual closure parts, e.g. the closure shell 109 or the like, by means of a two-component injection molding, by printing or spraying, of sealing material, by partially immersing the closure in sealing materials or by pressing or plugging a sealing shell element onto correspondingly interlocking closure elements.
  • FIGS. 1-10) The exemplary embodiment shown (FIGS. 1-10) is essentially the same in its functions as an exemplary embodiment from the earlier application P 33 41 759.8-27, which is shown there in FIGS. 3-6. However, it represents a maximum simplification both in terms of the extremely advantageous, but still very complicated control and switching mechanism shown there, and also in terms of the type of hermetic all-round seal.
  • the great technical advantage in the earlier exemplary embodiment was that, in contrast to all other exemplary embodiments of the same application, the strong compression spring acted on the closure and the weak compression spring on the circuit.
  • the achievement of the ready-to-write position was controlled there by pressing the push button both directly on the intermediate sleeve and directly on the A writing element acts, the writing element remaining connected through longitudinal slots in the intermediate sleeve to a circuit engaging the outer sleeve. This switches over during the advance outside the intermediate sleeve, whereby the writing element remains in the advanced position, after which the closure withdraws and releases the writing tip.
  • the complicated through-the-intermediate sleeve switching is solved in the present exemplary embodiment (FIGS. 1-10) by merely pressing the push button 101 (FIG. 1) in certain areas 106, 105 (FIGS. 1, 4, 8, 9) is executed in part and with these areas 106 and 105 acts on the intermediate sleeve 104 (Fig. 1 - 1b).
  • the pushbutton 101 acts in the area that remains free through the partial shells 106 and 105 on a special, longitudinally displaceable switching part 108 with a lateral circuit 3 '(preferably a heart curve circuit with a free-running ball) engaging on the outer housing 31 (FIG. 1 - 1b and Fig. 10), this switching part 108 in turn acting on the writing element 2.
  • both the intermediate sleeve 104 with the closure 109, 99, 102 are moved forward against the pressure of the spring 9 by the push button area 105, and the writing element 2 is moved via the switching part 108.
  • the switching part 108 is additionally held in a recess 103 of the push button 101 via a rear extension 107. This ensures that even if the switching part 108 is maximally displaced against the push button 101 to the front, this is still held exactly in the position parallel to the axis and is therefore held in place at the switch point 59 at the latest by the switching ball, thereby simultaneously mounting the push button 101 once , remains held forever in the rear housing part 31.
  • the push button 101 and the circuit 108 that is precisely matched to it form a fixed functional unit.
  • the hermetic closure of the writing tip 26 could also be simplified and perfected at the same time in the present exemplary embodiment, in that all sealing functions on the outside and on the inside of only one with the respective pressure shell 109 (FIG. 1 and Fig. 2) firmly connected sealing shell 99 (in the present case, two in total).
  • the sealing shell 99 is received and fixed in a correspondingly shaped holding bracket 110 of the pressure (half) shell 109 (FIGS. 2 and 3), the edge regions 100 of the elastic sealing shell 99 protruding a little beyond the edge of the sealing shell 109 (FIG. 7) to ensure the necessary closure pressure on the sealing joints during the closure (Fig. 1, 5 and 6). Since a half-shell bending element would have very little bending elasticity, the bending elements 102 of the closure 109 and 99 are also designed to be narrow, elastic webs.
