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 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 readiness for writing 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 relative to the latter axially to a limited extent and the segments forming the closure part of the housing are mounted on the inner sleeve, are radially outward under tension and partially outside the outer n sleeve are located 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 is biased towards the storage position
  • Such a writing instrument is known from DE-C 489 806.
  • a writing instrument is known from US-A-4,540,300 in which the tip section of the writing instrument is surrounded by a tubular elastic cylinder which is squeezed flat in the storage position of the writing instrument and thus closes the space around the writing tip.
  • This writing instrument has the disadvantage that this hose insulation takes up a relatively large amount of space and also tends to stick together when the writing instrument is brought into the ready-to-write position. This affects the tip of the lead and deteriorates the seal.
  • the invention is therefore based on the object of improving known writing instruments in such a way that, with simple manufacture, an optimal sealing of the space around the writing tip is achieved, which does not subside over time.
  • 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 together form a hermetically sealed chamber surrounding the tip section .
  • the abutting edge regions of the sealing shells advantageously protrude beyond the recess and consist of an elastically sealing material.
  • the closure 109, 102, 99 can be used to achieve a symmetrical shape during the writing state, also be made in three or more parts. 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 or shells 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, for example the closure shell 109 or the like, by means of a two-component injection molding, by printing or spraying on sealing material, by partially dipping the To achieve closure in sealing materials or by pressing or plugging a sealing shell element onto a correspondingly interlocking closure element.
  • FIGS. 1-10) has essentially the same 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 readiness to write position was controlled there by 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, as a result of which the writing element remains in the advanced position, after which the closure retracts 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.
  • both the intermediate sleeve 104 with the closure 109, 99, 102 are pushed 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.
  • This pressure actuation continues until the switching part 108 switches over with the lateral circuit 3 'at point 59, after which the pressure actuation subsides and the circuit 3' engages with the writing element 2 in the advanced position (FIG. 1a) and there from the Spring 10 is fixed.
  • the intermediate sleeve 104 with the push buttons 101, 105, 106 and the front closure 109, 99, 102 is pushed further back, finally exposing the writing tip 26 and the writing element tip section 4 by means of corresponding fixing shoulders 112 of the pressure shells 109 is clamped without touching the sealing shells 99 while the spring 9 is relaxed and the spring 10 is tensioned (Fig. 1 b).
  • the switching part 108 is additionally held in a recess 103 of the push button 101 via a rear extension 107.
  • 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 mounting bracket 110 of the pressure (half) shell 109 (FIGS. 2 and 3), the edge regions 100 of the elastic sealing shell 99 projecting 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.

Abstract

Un appareil d'enregistrement avec un boîtier en forme de manchon et un dispositif de fermeture automatique pour la pointe d'impression, qui est améliorée par le fait que l'élément de commande possède un systéme de commuation mécanique (3'), où le ressort (10) qui maintient l'élément d'impression (2) contre le boîtier appuie contre le manchon intérieur (104); où le systéme de commutation mécanique (3') agit sur le manchon extérieur (1, 31); où la force de rappel du ressort (10) qui maintient l'élément d'impression (2) contre le manchon intérieur (104) est plus faible que celle d'un ressort (9) qui maintient le manchon intérieur (104) contre le manchon extérieur (1, 31); et où l'élément de commande se compose de deux éléments qui peuvent être déplacés axialement l'un par rapport à l'autre, dont le premier (104, 105, 106) agit sur le manchon intermédiaire (104) et le second (107, 108) agit sur l'élément d'impression, porte le système de commutation mécanique (3') et est commandé par le premier élément (101, 105, 106).
