Definitions

  • the invention relates to a writing instrument according to the preamble of claim 1.
  • Such a writing instrument is known from DE-OS 35 18 069.
  • This writing instrument has a two-piece collet as a closure for the associated writing lead.
  • the two halves of the closure are provided on the inside with a rubber-like plastic part and are closed by the deflected force of a very strong compression spring.
  • this writing instrument has a control mechanism in order to coordinate the movement of the writing lead into the writing state with the sealing closure in such a way that neither the writing tip nor the seals can be damaged.
  • This known writing instrument is put into the writing state by actuating the rear push button, like a ballpoint pen.
  • the mine is engaged by a direct switching system in the advanced state, with the closure, which is directly controlled in parallel, being withdrawn laterally behind the mine.
  • This known writing instrument does offer all the prerequisites that are necessary for an inexpensive and absolutely reliable automatic closure.
  • a common problem with the use of such writing instruments is, however, that users, especially if they have to deal with something else for a short time, simply leave the liquid pen unlocked, as they are used to with ballpoint pens, whereupon the devices begin, to dry up. This forgetting to lock the pen occurs regardless of whether the liquid pen has a lock that can be operated at the push of a button or a conventional push-on cap.
  • the basic problem with liquid pens is that you forget to sell them close, is therefore only by the closability by
  • the object of the invention is therefore to create a writing instrument of the type mentioned at the outset which closes automatically after a defined period of time.
  • the writing instrument of the type described at the outset is largely redesigned except for the closure.
  • the writing instrument now only consists of an outer sleeve, a gas pressure-tight closure, a writing lead and a timer element acting between the lead and the outer sleeve.
  • the writing lead is no longer firmly anchored to the outer housing when it is pushed forward, as is generally the case with Ballpoint pens is common, but is located above an attachment at the front mine tip in an unstable anchorage that interacts with the timer element.
  • the timer element is arranged in a separate grip zone which is mounted on the outer sleeve.
  • the lead comes into unstable engagement with the timer element.
  • the index finger, thumb and middle finger usually press into the three recesses provided in the grip zone, where
  • one of the three grip zones is a single part which can be moved independently of the outer sleeve and which transfers the pressure of the writing hand to the latched attachment. This increases the pressure between the unstable anchorage (or the time switch) and the attachment of the mine that is locked into it,
  • the unstable anchoring of the writing lead becomes a stable anchoring during writing.
  • the writing lead is anchored as firmly as usual.
  • the writing lead releases from the latching in the advanced position and moves automatically, without any further external influence, into the closed state fully automatically.
  • the other forms of closure by push button actuation are also used to anchor the writing lead stably when writing and unstable in the state of not writing.
  • This timer mechanism can thus be applied to any conceivable system of the cap closure at the push of a button or rotation, etc.
  • the time switch function is fulfilled by other mechanisms, e.g. an electronic system that registers whether or not writing via the warmth of the hand, the writing movements or the diagonal / horizontal position of the writing instrument and, when not writing after a certain, selectable time, releases the snap-in of the advanced writing lead, whereupon the latter automatically moves into the Locked state moved.
  • other mechanisms e.g. an electronic system that registers whether or not writing via the warmth of the hand, the writing movements or the diagonal / horizontal position of the writing instrument and, when not writing after a certain, selectable time, releases the snap-in of the advanced writing lead, whereupon the latter automatically moves into the Locked state moved.
  • whether or not writing is possible is also possible via an air / gas / water system, which is compressed over the grip zone during writing and passes the pressure of the fingers on to a holding system for the writing element.
  • FIG. 1 shows a longitudinal section through an embodiment of the writing instrument in the writing position while writing.
  • Figure 1a is a longitudinal section through the writing instrument of Figure 1 in the writing position while not writing.
  • FIG. 2 shows a longitudinal section through the writing instrument according to FIG. 1, which is in the process of being switched into the closed state automatically or by pressure actuation;
  • FIG. 3 shows a plan view of the opened closure 1; 4 shows a cross section through the closure from FIG. 3; 5 shows a plan view of the outer sleeve 2;
  • FIG. 6 shows a plan view of the separate grip zone part 3 with a timer
  • FIG. 7 shows a cross section through the grip zone of the outer sleeve 2 from FIG. 5;
  • Fig. 8 is a plan view of the rear part of the writing instrument from Fig. 1b.
  • FIGS. 1-8 The embodiment of the writing instrument shown in FIGS. 1-8 has a one-piece outer sleeve 2 and a one-piece closure 1 (FIG. 1b), which extends over one
  • Film hinge 19 can be opened in two halves 12 (Fig. 3).
  • the closure halves 12 of the closure 1 are each provided with a rubber-elastic sealing half-shell 5 (FIGS. 1 and 3).
  • the closure 1 is by a
  • the writing instrument has a writing lead 4, which is arranged in the outer sleeve 2.
  • the writing refill 4 is biased against the closure 1 by means of a small spring 7, the spring 7, in order to keep the lead tip 14 and thus the length of the writing wick as short as possible, partially sinks into a special spring pocket 16 which is embedded in the rear end of the closure 1 (e.g. Figs. 1 and 3).
  • the writing lead 4 In the closed state (FIG. 16), the writing lead 4 is supported against a projection 18 at the rear via a special shoulder 17, which is located at the tip of the lead 14.
  • the writing tip 9 of the writing refill 4 which is at risk of drying out, is hermetically and pressure-tightly sealed within the sealing half-shells 5 of the closure 1 during the closed state (FIG. 16).
  • the writing instrument has a grip zone 10 consisting of three recessed grips (FIGS. 1, 5 and 7), one of the recessed grips consisting of a separate grip zone part 3 (FIG. 1), which is located in a special recess 11 (FIGS. 5 and 1) on the outer sleeve 2 (FIG. 1, 5, 6 and 7).
  • the end 13 of the writing lead 4 which protrudes outwards from the outer sleeve 2 itself, is pressed down instead of an otherwise usual push button (from FIG. 1b to FIG. 1a).
  • the opening shoulder 15 of the mine tip 14 meets the Opening projection 21 within the closure 1, the two halves 12 of the closure 1 being opened.
  • the opening process is such that the elastic seals of the sealing half-shell 5 are not touched by the writing tip 9.
  • the rear seal 22 of the sealing half-shell 5, which rests directly on the lead tip 14, is also lifted off during the opening after a very short grinding movement (about 0.5 mm) from the lead tip 14, so that it does not during the entire feed and when writing is touched by the mine tip 14.
  • this support is a relatively unstable support. Only when the user starts to write will the support of the writing lead 4 become stable (FIG. 1). This is done in that when writing one of the three writing fingers presses on the grip zone part 3, whereby the timing switch protrusion 24 is pressed somewhat more strongly than the non-writing on the shoulder 17 of the writing lead 4 (FIG. 1). This slight increase in pressure from the grip zone part 3 over time Switching projection 24 on the shoulder 17 is thus sufficient to keep the latching of the writing lead 4 permanently stable in the writing state during writing.
  • the grip zone part 3 is slowly raised above the timer switch protrusion 24 by the shoulder 17, the force of the spring 7 against the writing lead 4 being the cause of this.
  • the lifting of the grip zone part 3 is also facilitated in that the front part 25 of the grip zone part 3 is made thinner and flexible, while the rear part 28 is thicker and inelastic.
  • the engagement of the writing lead 4 thus gradually changes from a stable to an unstable engagement. So far the grip zone part 3 over a certain one
  • Writing refill 4 is moved back without vibration so that no tendency to leakage can develop, i.e. the writing refill 4 can easily be equipped with a high writing capacity or a large ink supply.
  • the shoulder 17 of the writing lead 4 in various sections around the writing lead 4 has different flattened angles with which it can come to rest against the timing projection 24, the time after which the writing instrument closes automatically can be dated Change users.
  • different ner angle can be incorporated on the shoulder 17 other features to change the course of time, such as different surfaces and shapes, etc. on the individual sections of the shoulder 17.
  • the change in the closing time 23 associated with the individual contact angles of the shoulder 17 can be found on Read the rear end 13 of the writing lead 4 via the time setting notch 20.
  • Extend or shorten writing lead 4. The user can also use the mass production to correct the possible variation widths of the structurally predetermined shutter speed.
  • the automatic shutter speed can be designed
  • this includes the shape and nature of the grip zone part 3, how thin or thick the front, flexible part 25 and the rear, less elastic part 28 are made (FIGS. 6 and 2). This also includes the shape and surface condition of the timer projection 24 and the shoulder 17.
  • the materials from which the parts of the time mechanics are made also play a significant role. For example, it is conceivable to manufacture the timer projection 24 together with the grip zone 3 from a harder material with a rough surface and the shoulder 17 from a softer material with a smooth surface, etc.
  • Another way of influencing the shutter speed is to coat the surface of the otherwise hard material part with a soft plastic on one or more of the parts which are unstable to support the writing state, for example 17, 24 or 3, as a result of which the latches slide past one another can be further slowed down. Furthermore it is also possible, e.g. to incorporate certain patterns into a somewhat enlarged time switch projection 24, which unstably engage with corresponding patterns on the adapted shoulder 17.
  • Another possibility is, for example, by casting a small pivotable flap on the inner side of the grip zone part 3, which cooperates with a corresponding projection in the region of the shoulder 17, so that this pivoting flap when sliding back Writing lead 4 first has to lift the grip zone part 3 briefly before the writing lead loses its rear support and switches to the locked state.
  • the regulation of the timing can also be supported in that the inner regions of the outer sleeve 2, which lie opposite the shoulder 17 during the writing state, are also included in the switching sequence.
  • certain angles or projections know the shoulder 17 pressing against the projection 24 when the writing lead slides back, or the inner surface texture of the outer sleeve 2 can also interact with the shoulder 17 here, similarly to the possibilities between the timing projection 24 and the switch 17 has been described
  • the type and pressure strength of the compression spring 7 and the compression spring 6 also play an important role.
  • the constructionally specified closing time would expediently be longer for writing implements with normal writing inks that are less prone to drying out, for example 15 minutes, and for writing implements with rapidly evaporating, alcoholic

Abstract

Un instrument pour écrire à fermeture sans capuchon peut être actionné par un bouton poussoir ou un autre mécanisme. Pour écrire, la mine est placée dans une position verrouillée d'une instabilité définie. Lorsque l'on cesse d'écrire, la mine rentre automatiquement après un laps de temps prédéterminé. L'instrument pour écrire se ferme donc automatiquement après un laps de temps prédéterminé sans aucune autre intervention extérieure.
