Description

  

  Dispositif de pivotement de mobile dans les mouvements de montres  et autres instruments.    L'objet de l'invention est un dispositif de  pivotement de mobile dans les mouvements  de montres et autres instruments. Il est ca  ractérisé en ce que l'un au moins des pivots  du mobile est monté dans un coussinet en  métal dur, rapporté au support du mobile et  tenant lieu de pierre à pivot.  



  Le dessin ci-joint montre, à titre d'exemples  d'exécution, le dispositif de pivotement et  quatre variantes de coussinets.  



  La fis. 1 représente ladite forme d'exécu  tion en coupe; les fis. 2 à 5 montrent égale  ment en coupe les variantes de coussinets.  



  Dans la fis. 1 du dessin, 1 désigne un  pont de mobiles, par exemple d'un mouve  ment de montre. 2 est l'axe d'un mobile qui  est monté, par le pivot 2' de l'axe, dans le  trou 3 d'un coussinet 4. Ce dernier est cons  titué par une rondelle en métal dur, de pré  férence en acier ou en un alliage approprié  et remplace la pierre, naturelle ou artificielle  (synthétique), généralement utilisée dans ce  but en horlogerie.  



  Le coussinet 4 en métal présente la même  forme et les mêmes dimensions qu'une     des       pierres à pivot usuelles; comme ces dernières,  il est serti dans le pont 1 et comporte une  gouge 5.     La,    face extérieure, mais surtout la  gouge 5 du coussinet recevra de préférence  un beau poli, de manière à donner l'illusion  que le pivot est empierré.  



  Le coussinet 4 pourrait être monté sur le  pont 1, par l'intermédiaire d'un chaton.  



  Les fis. 2 à 5 montrent en coupe les  quatre variantes d'exécution du coussinet qui  se distinguent entre elles soit par la forme  extérieure, soit par - la forme du trou de pivot.  



  Un mouvement de montre, un compteur  ou tout autre instrument analogue peut com  porter un ou plusieurs mobiles montés dans  leur support     conformément    à la présente in  vention.



  Device for rotating a mobile in the movements of watches and other instruments. The object of the invention is a device for pivoting a mobile in the movements of watches and other instruments. It is characterized in that at least one of the pivots of the mobile is mounted in a hard metal pad, attached to the support of the mobile and taking the place of a pivot stone.



  The accompanying drawing shows, as an exemplary embodiment, the pivoting device and four variants of the bearings.



  The fis. 1 shows said embodiment in section; the fis. 2 to 5 also show the bearing variants in section.



  In the fis. 1 of the drawing, 1 designates a bridge of mobiles, for example of a watch movement. 2 is the axis of a mobile which is mounted, by the pivot 2 'of the axis, in the hole 3 of a bearing 4. The latter is constituted by a hard metal washer, preferably in steel or in an appropriate alloy and replaces the stone, natural or artificial (synthetic), generally used for this purpose in watchmaking.



  The metal pad 4 has the same shape and the same dimensions as one of the usual pivot stones; like the latter, it is crimped in the bridge 1 and comprises a gouge 5. The, outer face, but above all the gouge 5 of the bearing will preferably receive a good polish, so as to give the illusion that the pivot is stoned.



  The pad 4 could be mounted on the deck 1, via a kitten.



  The fis. 2 to 5 show in section the four alternative embodiments of the bearing which differ from one another either by the external shape or by the shape of the pivot hole.



  A watch movement, a counter or any other similar instrument may include one or more moving parts mounted in their support in accordance with the present invention.
