Definitions

  • the invention relates to a writing instrument using a removable ink cartridge and more specifically to the means for loading and unloading the cartridge in the writing instrument.
  • the invention aims to facilitate the unloading of the used cartridge and the loading of a new cartridge.
  • the writing instrument further comprises articulation means connecting the main body and the rear body, said means of articulation allow pivoting of the rear body relative to the main body around an articulation axis perpendicular to the longitudinal direction, between a loading position in which the access opening to the housing extends away from the main body and an unlocked position in which the longitudinal direction and the direction loading are substantially merged.
  • the cartridge change does not require to separate then reassemble the back body and the body main, particularly by unscrewing and screwing, to change the cartridge. It is therefore more convenient and faster.
  • the rear body remains linked to the main body, there is no risk of losing it while loading a new cartridge.
  • the first end of the rear body in the unlocked position, is disposed between the hinge pin and the first end of the main body.
  • the hinge means allow the sliding of the rear body in the longitudinal direction between the unlocked position and a position of use.
  • the cartridge is engaged in the main element to feed the writing tip ink and in the case of a cartridge incorporating the tip of the pen.
  • writing in particular ball
  • the tip is passed through the main body and out through the first end.
  • the articulation means prohibit pivoting of the rear body relative to the main body about the hinge axis during sliding in the longitudinal direction between the position of use and the position unlocked.
  • the hinge means comprise a rod having two flats sliding between two guiding surfaces disposed opposite one another defining a groove, said guide surfaces having a recess adapted to receive the rod and allow pivoting of the rod relative to the groove about the hinge axis when the writing implement is in the unlocked position, to allow pivoting of the rear body to the loading position of the writing instrument.
  • the recess only allows the pivoting of the rod with respect to the groove about the hinge axis on a limited amplitude at the loading position of the writing instrument. .
  • the movement of the rear body pivoting about the pivot axis relative to the main body being limited to the loading position, it is easier to load the cartridge into the housing of the rear body while holding the writing element .
  • the rod and the recess have closely complementary shapes, cooperating with each other to maintain the rear body in the loading position.
  • the pivotal amplitude of the rod relative to the groove about the hinge axis between the unlocked position and the loading position is between 20 degrees and 50 degrees.
  • This amplitude is sufficient to load or remove a cartridge and allows easy maintenance of the main body and the rear body.
  • the writing instrument further comprises a cap for covering the writing tip, indexing means for positioning the cap relative to the main body about the longitudinal direction and the holding means for retaining by clipping the cap relative to the main body in translation along the longitudinal direction.
  • the cap held on the main body is indexed in rotation relative to said main body.
  • FIGS. 1 to 9 illustrate a pen holder 1 essentially comprising a main body 2 extending in a longitudinal direction 10 between a front end 2a and a rear end 2b, a writing pen 6 and a pipe 7 fixed to the main body 2 near its front end 2a, a rear body 4 connected to the main body 2 near its rear end 2b and a cap 8 for protecting the writing pen 6.
  • the rear body 4 comprises a housing 14 extending in a loading direction 12 between a front end 14a and a rear end 14b.
  • the housing 14 contains an ink cartridge 8 held by a tab 40.
  • the main body 2 comprises two flanges 32 extending substantially in the longitudinal direction 12 on either side of the rear body 4.
  • the flanges 32 are interconnected by a rod 22 ' extending through the rear body 4 along an axis of articulation 20 perpendicular to the longitudinal direction 10 and the loading direction 12.
  • the rod 22 has two flats 24a, 24b extending substantially parallel, so that the rod 22 has a substantially rectangular shape in cross section.
  • the rear body 4 is articulated with respect to the main body 2 by a groove 26 in which the rod 22 is movable.
  • Said groove 26 comprises two guide surfaces 26a, 26b extending parallel and on either side of a median plane P containing the hinge pin 20 and parallel to the loading direction 12.
  • the longitudinal direction 10 and the loading direction 12 are then substantially coaxial.
  • the wings 32 extending on either side of the rear body 4 cooperate with flat lateral flanks of the rear body 4 to allow the rear body 4 to translate relative to the main body 2 in the longitudinal direction 10 between the unlocked position and the position of use.
  • the rear body 4 is retained in the use position 2 by means of a godron defining a boss 30 projecting on the guide surface 26b.
  • this restraint can be overcome by elastic deformation by exerting a force along the longitudinal direction 10 between the rear body 4 and the main body 2.
  • the pen is then in the unlocked position illustrated in the Figures 4 and 5 .
  • the rod 22 is positioned facing the recesses 28a and 28b defining recesses in the guide surfaces 26a and 26b of the groove 26.
  • the rear body 4 can then pivot about the hinge axis 20 relative to the main body 2 an angle ⁇ by causing the rod 22 to enter the recesses 28a and 28b provided for this purpose in the groove 26.
  • the angle ⁇ is advantageously between 20 ° and 50 °, so as to clear the access orifice 16 extending to the front end 14a of the housing 14 and thus remove the cartridge 8 and replace it with a new cartridge by engaging substantially in the direction of engagement 12 and bringing it in abutment against the tab 40 by a slight pivoting about an axis substantially parallel to the hinge axis 20.
  • the new cartridge is carried out in opposite direction by pivoting the rear body 4 about the hinge pin 20 to bring the loading direction 12 in correspondence with the longitudinal axis 10 of the main body 2, then the cartridge 8 is engaged in the main body 2 by translation towards the front end 2a of the main body 2 in the longitudinal direction 10, until the pen is locked in the use position by means of the boss 30.
  • the main body 2 comprises near its front end 2a two pins 34 projecting substantially perpendicular to the longitudinal direction 10 and the cap 18 has two complementary grooves 36 extending in one direction engagement member 42 substantially corresponding to the longitudinal direction of the cap 18.
  • the grooves 36 extend between an insertion end 36a and a stop end 36b. Close to the stop end 36b, the groove 36 has a narrowing forming a neck 38, so that the groove 36 has near its stop end 36 a substantially ⁇ shape for holding the cap 18 in place. closed position. In this position, the cap 38 is retained on the main body 2 near the front end 2a via the neck 38 releasably holding the pins 34 at the stop end 36b of the groove 36. o-ring 44 held on the main body 2 is compressed against the cap 18 to improve the seal between the cap 18 and the main body 2.
  • FIG. 10 to 12 The embodiment variant illustrated in Figures 10 to 12 is essentially different from the illustrated Figures 1 to 9 in that the pins 34 and the cap 18 have been replaced by a polarizer 134 and a godron 137 formed on the main body 102 and a cap 118.
  • the polarizer 134 extends in the extension of the substantially cylindrical outer surface 146 of the main body 102, that it is flush with the direction of elongation radially and protrudes in the longitudinal direction 10.
  • the cap 118 internally has a blind housing 136 of complementary shape to that of the polarizer 134 extending in the engagement direction 42 of the cap 118. It further comprises a rod 138 consisting of three portions protruding internally in the cap 118 and coming to engage elastically with the godron 137, itself consisting of three corresponding portions.
  • Clipping of the cap 118 on the main body 102 is by translation of the axis 42 in the longitudinal direction 10, engaging the polarizer 134 in the housing 136 and the overlap portions of the rod 138 on the portions of the godron 137.
