Definitions

  • the invention relates to a writing instrument, in particular a pen of the type comprising a pointed writing unit and an ink reservoir intended to continuously moisten the tip of the pen.
  • the pens produced in several forms include a writing unit and an ink tank mounted in a protective sleeve and grip for writing.
  • This sleeve is generally formed of a metallic or plastic tubular element, either when the writing unit with its reservoir is fixed, or when it can be protruded and returned by means of a push-button, screw or d 'other kind.
  • DE-107 200 proposes a pencil holder, the novelty of which consists in the fact of comprising a body formed by two wooden parts which are not glued but joined in an opening manner by means of at least one external elastic ring, these two parts delimiting a channel in which the writing element is found.
  • the two parts are not coupled nor movable with clamp relative to the other, but one can only make them slide laterally one on the other.
  • the aim of this invention is to propose a writing instrument, in particular a pen structured in a manner different from known embodiments, as the writing unit and the ink tank are enclosed in a compound body. of two complementary and associated halves that can be opened and closed like a clamp.
  • Another object of the invention is to provide a writing instrument in the form of a pen in which the writing unit can move in the axial direction to protrude during use and return to the protective position simply by opening and closing the clip body.
  • the invention relates to a writing instrument at least according to claim 1.
  • the envisaged writing instrument comprises a writing unit 10 enclosed in a clamp body 11.
  • the writing unit 10 comprises a tip 12 and a tubular ink reservoir 13, this reservoir having a pawl 14 at its end or in an intermediate position.
  • the clamp body 11 is formed by two elements 15-15 'opposite and articulated one on the other.
  • the element 15 has, in its intermediate part, at least one heel which serves as a point of ap meme 17 intended to engage with a corresponding recess 18 pressed on the opposite element 15 ′.
  • a pressure spring 16 which tends to hold the lower parts of the elements 15-15 ′ brought together and centered on a tenon 16 ′ if necessary and also between two recesses 16 "pressed on the opposite faces of the two elements 15-15 ′.
  • a pressure spring like the spring 16
  • another elastic element may be used, for example a leaf spring possibly made, if possible, with the material used for the elements 15-15 ′ of the body 11, integrally or separately from these elements.
  • two longitudinal channels 19 together define a housing for the reservoir 13 of the writing unit 10.
  • a seat 20 is intended to couple and cooperate with the pawl 14 of the reservoir 13 and delimit the longitudinal movements of the reservoir between the two elements, in the aforementioned seat two small intermediate teeth 20 meshing with the heads of the cli quet 14 to define and stop, by means of the ratchet itself, the writing unit in the projecting or retracted position.
  • the elements 15-15 ′ On the opposite side of the fulcrum 17, where the spring 21 is located, the elements 15-15 ′ have two tapered arms 21, on which one acts manually to open the clamp body in opposition to the action of the element elastic. On one of the arms 21 one can mount or insert a clasp 22 with a gusset; inside the two arms 21 there are two partitions 21 ′ which pressing one against the other limit the movement of the two elements 15-15 ′ for the opening of the clamp body.
  • each element 15-15 ′ of the clamp body 11 has, longitudinally at the two sides of the channels 19, projecting edges 23 intended to couple with those of the opposite element to prevent any reciprocal displacement in transverse direction of the two elements.
  • the writing unit can be moved by gravity towards the outside of the body for the use of the writing instrument (cf. Fig. 2). Then, by further spreading the elements, the writing unit can be brought into the body in the rest position.
  • the maneuver is simple, easy and quick to perform and the writing instrument comes with a structure and a shape quite different compared to the known technique in terms of feathers.
