Description

  

      Dispositif    de pivotement d'un mobile d'horlogerie ou de petite     mécanique       La présente     invention    a pour objet un dispositif  de pivotement d'un mobile d'horlogerie ou de petite  mécanique.  



  Ce     dispositif    est caractérisé par le fait que l'arbre  du mobile présente, à au moins une de ses extrémi  tés, une creusure axiale dans laquelle pénètre une  saillie du     palier,    l'axe de ladite saillie étant situé dans  le prolongement de l'arbre.  



  Le dessin représente, à titre d'exemple, une  forme d'exécution de l'objet de     l'invention.     



  La figure est une coupe axiale d'un palier et de       l'extrémité    de l'arbre du mobile, non représenté, dont  le pivotement est assuré par le     dispositif    suivant l'in  vention.  



  L'arbre représenté est désigné par 1. Son extré  mité présente une creusure coaxiale 2 dans laquelle  est chassée une crapaudine en pierre 3.  



  Le palier comprend une saillie constituée par une  tige 4 dont     l'extrémité    conique 4a     pénètre    dans le  trou 5, conique également, de la crapaudine 3. Cette  tige 4 est chassée dans une rondelle 6 reposant sur  un siège tronconique 7 ménagé dans une bague fixe  8 chassée     dans    une douille 9 destinée à être     elle-          même    chassée dans le bâti du mouvement d'horloge  rie ou de l'appareil sur lequel est monté le présent       dispositif.    La bague 8 et la douille 9 forment ensem  ble un     support    de palier.

      En outre, un ressort à boudin 10 prend appui sur  le fond 9a de la     douille    9, d'une part, et sur la ron  delle 6, d'autre part, par l'intermédiaire d'un man  chon 11     coulissant    à l'intérieur de la douille 9 et pré  sentant un rebord     intérieur    11a. Ce dernier prend  appui sur la rondelle 6, sous l'action du ressort 10,  et empêche la tige 4 de basculer lors des chocs laté  raux que subit l'arbre.  



  Ainsi, lors de tels chocs, la tige 4 se déplace laté  ralement, parallèlement à elle-même, montant le long  de la surface tronconique du siège 7, à l'encontre de  l'action du ressort 10. Lors des chocs axiaux, la ron  delle 6 quitte le siège 7, comprimant le ressort 10.  



  En variante, on pourra prévoir le cas où la     creu-          sure    2 de     l'arbre    1 recevra directement l'extrémité  de la     saillie    du palier, cette saillie pouvant alors être  en pierre.  



  L'invention pourra également s'appliquer au cas  où le     palier    n'est pas amortisseur de chocs, comme  dans l'exemple représenté, mais     fixe,    sa     saillie    étant  montée rigidement sur lui.



      Pivoting device of a timepiece or small mechanical mobile The present invention relates to a device for pivoting a timepiece or small mechanical mobile.



  This device is characterized by the fact that the mobile shaft has, at at least one of its ends, an axial recess into which a projection of the bearing penetrates, the axis of said projection being located in the extension of the shaft. .



  The drawing represents, by way of example, an embodiment of the object of the invention.



  The figure is an axial section of a bearing and of the end of the shaft of the mobile, not shown, the pivoting of which is provided by the device according to the invention.



  The tree represented is designated by 1. Its end has a coaxial recess 2 in which a stone frame 3 is driven.



  The bearing comprises a projection formed by a rod 4 whose conical end 4a penetrates into the hole 5, also conical, of the slider 3. This rod 4 is driven into a washer 6 resting on a frustoconical seat 7 formed in a fixed ring. 8 driven into a socket 9 intended to be itself driven into the frame of the clock movement or of the apparatus on which the present device is mounted. The ring 8 and the sleeve 9 together form a bearing support.

      In addition, a coil spring 10 is supported on the bottom 9a of the sleeve 9, on the one hand, and on the ron delle 6, on the other hand, by means of a sleeve 11 sliding at the inside the sleeve 9 and having an inside rim 11a. The latter is supported on the washer 6, under the action of the spring 10, and prevents the rod 4 from tilting during lateral impacts to which the shaft is subjected.



  Thus, during such shocks, the rod 4 moves laterally, parallel to itself, rising along the frustoconical surface of the seat 7, against the action of the spring 10. During axial shocks, the ron delle 6 leaves seat 7, compressing spring 10.



  As a variant, provision could be made for the case where the recess 2 of the shaft 1 will directly receive the end of the projection of the bearing, this projection then being able to be made of stone.



  The invention can also be applied in the case where the bearing is not shock absorber, as in the example shown, but fixed, its projection being mounted rigidly on it.
