Description

  

  Palier pare-chocs pour pièce d'horlogerie.    Le palier pare-chocs pour mobile de pièces  d'horlogerie selon la revendication du brevet  principal comporte une pierre percée dont le  forage est à une distance telle du plan des  points d'appui de ladite pierre sur le mouve  ment qu'un effort latéral exercé sur le pivot  du mobile fasse basculer la pierre autour de  son arête inférieure à l'encontre de l'effort  d'un ressort tendant à la ramener en place.  



  Dans le palier selon la présente invention,  la pierre percée et la surface sur laquelle elle  s'appuie sont conformées de façon qu'au repos  la pierre ne     repose.que    sur l'arête formée par  la rencontre des surfaces de sa     creusure    et de  sa base. Pour arriver à ce résultat, on peut  faire la     surface    inférieure de la pierre convexe  et la. surface d'appui plate. On peut avoir  aussi la surface d'appui convexe et la base de  la pierre plate. La base de la pierre et la sur  face d'appui pourraient aussi être toutes les  deux convexes.  



  Le dessin annexé montre,     Î'Î.    titre d'exemples,  deux formes d'exécution de l'objet de l'inven  tion, toutes deux en coupe diamétrale.    Dans ces figures, 1 désigne le pont dans  lequel le palier doit trouver place. Il y a été  creusé une cavité 2 ayant vers son fond 3 une  partie cylindrique 4 de plus     petit    diamètre  et allant en s'évasant, à partir du cercle qui.  au repos, est en contact avec l'arête     extérieure     inférieure de la pierre, jusqu'à rencontrer un  rebord 5. Le fond est percé en 6 pour laisser  passer le pivot 7 du     mobile    qui pénètre dans  la pierre percée 8.

   Cette dernière a sa base  inférieure 9 convexe si bien que le contact  entre le fond 3 de la cavité et la pierre ne se  donne que le long de l'arête 10 qui est celle de  la creusure 11.  



  Sur la pierre percée 8 est placé le chaton  12 du     contre-pivot    13 qui reçoit la pression  d'un ressort 14.  



  La construction est telle que de petits  chocs subis par le mouvement ne déplaceront  pas la pierre percée 8, car cette dernière     frotte     par ses bords contre la partie cylindrique 4 de  la cavité 2. Par contre, si le choc est     tel    qu'il  puisse être dangereux pour le pivot 7, la  pierre 8 basculera en tendant le ressort 14 qui      la ramènera en place sitôt que les effets du  choc auront cessé.  



  Dans la. forme d'exécution représentée en       fig.    2, la pierre percée 8 a sa base inférieure 9  perpendiculaire à l'axe du trou. Elle est main  tenue dans un chaton à périphérie conique  dont le cercle de base. est en contact avec     1e,4     parois cylindriques de la partie inférieure de  la cavité 2. Le fond 15 de cette cavité 2 est.       aussi    tronconique si bien que le contact entre  ce fond et la pierre percée ne se fait que par  l'arête circulaire formée par la rencontre de  la creusure 11 et de la surface inférieure de la.  pierre 8.  



  Dans le cas particulier, le palier est logé  dans -une pièce rapportée 16 qui sert de       coqueret.  



  Bumper bearing for timepiece. The bumper bearing for a moving part of timepieces according to the claim of the main patent comprises a drilled stone the bore of which is at a distance such from the plane of the points of support of said stone on the movement that a lateral force exerted. on the pivot of the mobile causes the stone to tilt around its lower edge against the force of a spring tending to bring it back in place.



  In the bearing according to the present invention, the pierced stone and the surface on which it rests are shaped so that at rest the stone only rests on the edge formed by the meeting of the surfaces of its recess and its based. To achieve this result, we can make the lower surface of the stone convex and the. flat bearing surface. We can also have the convex bearing surface and the base of the flat stone. The base of the stone and the bearing surface could also both be convex.



  The accompanying drawing shows, Î'Î. As examples, two embodiments of the object of the invention, both in diametral section. In these figures, 1 designates the bridge in which the bearing must be placed. There was hollowed out a cavity 2 having towards its bottom 3 a cylindrical part 4 of smaller diameter and widening out from the circle which. at rest, is in contact with the lower outer edge of the stone, until it meets an edge 5. The bottom is drilled at 6 to allow the pivot 7 of the mobile to pass through, which penetrates into the drilled stone 8.

   The latter has its lower base 9 convex so that the contact between the bottom 3 of the cavity and the stone is only given along the edge 10 which is that of the recess 11.



  On the pierced stone 8 is placed the kitten 12 of the counter-pivot 13 which receives the pressure of a spring 14.



  The construction is such that small shocks undergone by the movement will not displace the pierced stone 8, because the latter rubs by its edges against the cylindrical part 4 of the cavity 2. On the other hand, if the impact is such that it can be dangerous for the pivot 7, the stone 8 will tilt by tensioning the spring 14 which will bring it back in place as soon as the effects of the shock have ceased.



  In the. embodiment shown in FIG. 2, the pierced stone 8 has its lower base 9 perpendicular to the axis of the hole. It is hand held in a kitten with a conical periphery including the base circle. is in contact with 1e, 4 cylindrical walls of the lower part of the cavity 2. The bottom 15 of this cavity 2 is. also frustoconical so that the contact between this bottom and the pierced stone is only made by the circular ridge formed by the meeting of the recess 11 and the lower surface of the. stone 8.



  In the particular case, the bearing is housed in an insert 16 which serves as a socket.
