Description

  

      Porte-mine.       L'objet de la présente invention est un  porte-mine,     caractérisé    en ce qu'il comporte  une tige pliante munie d'une     pointe,    articulée  par son extrémité opposée à la pointe     dans     l'extrémité opposée à la.

       usine    du porte-mine       d'un    logement longitudinal ménagé     dans,    le  corps du     porte-mine,    logement dans lequel la  dite tige repliée     peut    être maintenue, le     tout     de façon que ladite tige extraite de son loge  ment forme l'une des branches d'un compas  dont le corps du     porte-mine    forme     l'autre     branche.  



  Le     dessin        ci-annexé    représente, à     titre     d'exemple, une forme -d'exécution du porte  mine faisant l'objet de     l'invention.     



  La     fig.    1 est une vue en élévation du  porte-mine, la tige     pliante        étant        maintenue     en place     dans    son     loaement    pour l'usage habi  tuel du porte-mine.  



  La fia. 2 est une vue en élévation     orth-o-          gona.le    à la fia. 1. avec parties en coupe, la  tige pliante étant extraite de sou logement et  dépliée en position permettant     l'utilisation    du  porte-mine     comme    compas.  



  La     fig.    3 est une coupe suivant     III-III     de la fia. 1, et  la fia. 4 est une coupe suivant IV-IV  de la fia. 1.  



  Le     porte-mine    représenté     comprend    un  corps     tubulaire    1     .dans    une extrémité duquel  est vissé un ajutage 2     contenant    une pince 3  portant la mine 4     placés    sous l'action d'un  ressort non représenté. L'autre     extrémité    du  corps     tubulaire    1 porte une douille 5 fermée    par un     bouchon    fileté 6 et servant de magasin  pour les mines de réserve. La bague 7 portant  l'agrafe 8     sert    de manchon     couvre-joint    entre  le corps 1 et lia     dbuille    5.  



  La paroi du corps tubulaire 1 présente une  fente     longitudinale    9. Dans     l'extrémité    oppo  sée à la mine du corps tubulaire 1 :est     articulée     sur une goupille 10 une tige d'acier en deux  tronçons 11 et 12     articulés    entre eux par une  goupille 13. Le     tronçon    12     est    muni d'une  pointe rapportée 14. La tige 11-12 forme  l'une des branches d'un     compas    dont l'autre  branche     est    formée par le     corps    1 -du porte  mine.

   Lorsque le     tronçon    12 est replié contre  le tronçon 11 -comme représenté en     traits     mixtes dans la fia. 2, la tige peut être main  tenue à     l'intérieur    du     corps    1 par une bague  15     susceptible    de     -coulisser    sur le corps 1 et  de fermer la partie extrême de la fente     longi-          tudinalle    9 à     travers    laquelle la tige 11, 12  peut sortir -du     corps    1.

   Un     ress.ort-lame    16  tend à faire sortir l'a tige 11-12 de son loge  ment par la     fente    9 lors-que la bague 15 est  poussée vers     l'extrémité        côté    mine du porte  mine.     Le        ressort    16 assure     aussi    le     maintien     en place de la bague 15 en     position    de ferme  ture eu     faisant    appuyer     contre    elle     le        dos    ar  rondi du tronçon 11 de     la        tige.  



      Mechanical pencil. The object of the present invention is a mechanical pencil, characterized in that it comprises a folding rod provided with a point, articulated by its end opposite to the point in the end opposite to the.

       mechanical pencil factory of a longitudinal housing provided in the body of the mechanical pencil, housing in which said folded rod can be held, all so that said rod extracted from its housing forms one of the branches of 'a compass of which the body of the mechanical pencil forms the other branch.



  The accompanying drawing shows, by way of example, one embodiment of the mechanical pencil forming the subject of the invention.



  Fig. 1 is an elevational view of the mechanical pencil, the folding rod being held in place in its loaement for the usual use of the mechanical pencil.



  The fia. 2 is an elevational view orth-o- gona.le to the fia. 1. with parts in section, the folding rod being extracted from its housing and unfolded in position allowing the use of the mechanical pencil as a compass.



  Fig. 3 is a section along III-III of the fia. 1, and the fia. 4 is a section on IV-IV of the fia. 1.



  The mechanical pencil shown comprises a tubular body 1 .in one end of which is screwed a nozzle 2 containing a clamp 3 carrying the lead 4 placed under the action of a spring, not shown. The other end of the tubular body 1 carries a sleeve 5 closed by a threaded plug 6 and serving as a store for reserve mines. The ring 7 carrying the clip 8 serves as a joint cover sleeve between the body 1 and the dbuille 5.



  The wall of the tubular body 1 has a longitudinal slot 9. In the end opposite the mine of the tubular body 1: is articulated on a pin 10 a steel rod in two sections 11 and 12 articulated together by a pin 13 The section 12 is provided with an attached tip 14. The rod 11-12 forms one of the branches of a compass, the other branch of which is formed by the body 1 of the mechanical holder.

   When the section 12 is folded against the section 11 -as shown in phantom in the fia. 2, the rod can be hand held inside the body 1 by a ring 15 capable of sliding on the body 1 and closing the end part of the longitudinal slot 9 through which the rod 11, 12 can come out. -of the body 1.

   A spring-blade 16 tends to cause the rod 11-12 to come out of its housing through the slot 9 when the ring 15 is pushed towards the lead end of the mechanical pencil. The spring 16 also ensures that the ring 15 is held in place in the closed position by pressing against it the rounded back of the section 11 of the rod.
