Definitions

  • the present invention relates to a writing instrument and, specifically, means suitable for ensuring the maintenance of a cap on the body thereof.
  • this method of assembly by screwing requires, on the body of the writing instrument, in the vicinity of the writing tip, the presence of a thread, intended to cooperate with a corresponding thread, provided in the inner part of the cap. If the latter is concealed in the eyes of the user, it is not the same for the first, which, in terms of aesthetics, constitutes a serious drawback.
  • the present invention aims to provide means for securing by face a body and a pen cap, which do not have the above drawbacks.
  • the subject of the invention is a writing instrument of the type comprising a body and a cap which can be assembled by screwing, in which the scripting element is slidably mounted inside the body, characterized in that, firstly , the thread on which the cap can be screwed is formed on a part integral with the scripting element, in that, on the other hand, in the writing position, this threaded part is retracted in said body and, in that , thirdly, in the rest position, that is to say, when the cap is in place on the writing element, the cap bears against the body of the writing instrument under the action of an organ elastic return.
  • the cap is therefore applied against the body of the writing instrument during part of the screwing and also during the entire unscrewing phase, until its instantaneous release from the body.
  • the cap of which is screwed onto the body there is no gap between the cap and the body during the unscrewing phase, which is advantageous from an ornamental point of view. certain.
  • FIG. 1 to 3 show, in partial section, a writing instrument according to the invention, consisting of a fountain pen, respectively in the writing position, during the phase of fitting the cap, and in the position rest ;
  • FIG. 4 shows, in developed form, the profile of the groove used in a type of mechanism making it possible to implement the invention.
  • the writing instrument according to the invention essentially consists of a body 1, a writing tip 3, a mechanism 5 and a cap 7.
  • the writing tip 3 is equipped with a pen 11 and with ink supply means thereof, not shown in detail in the drawing. It is integral with a tube 13 ensuring, by an internal channel, the feeding of the pen, and the external part of which is part of a mechanism 5 known in the art for allowing a writing tip to come out and come in. by a simple action on a pusher.
  • Such a mechanism comprises a ring 15 screwed into the body 1, inside which the tube 13 slides.
  • This ring is provided with a circular groove 19.
  • the tube 13 is hollowed out on its outer wall with a groove 23, whose developed profile, known per se, has substantially the shape shown in Figure 4.
  • the grooves 19 and 23 have a depth substantially equal to the radius of a ball 21, which is interposed between said grooves.
  • a compression spring 25 bears, on the one hand, on the ring 15 and, on the other hand, on a circular sleeve 27 forming a stop integral with the tube 13. The spring 25 thus tends to bring the writing end piece 3 towards the inside of the body.
  • the user can start screwing the cap 7 of the pen onto the writing tip 3.
