Description

  

  Palier pare-chocs pour pivot de balancier de mouvement d'horlogerie.    _Le palier pare-chocs, objet de la présente  invention, est destiné à, un     pivot    de balancier  d'un mouvement d'horlogerie tournant dans  un     coussinet.    métallique. Dans le cas particu  lier, ce coussinet est maintenu librement à  l'intérieur du coqueret par un bras faisant  ressort et traversant aussi bien le coqueret  que la serge de la raquette dans des décou  pures prévues à cet effet. On obtient de cette  manière un tout susceptible d'absorber aussi  bien les     composantes    radiales que les compo  santes axiales des chocs que reçoit la montre  et ceci au moyen d'organes dont le coût mi  nime peut encore être supporté par le prix  de vente de mouvements du genre précité.  



  Le dessin annexé représente, à titre  d'exemple, une forme d'exécution du     palier     selon la présente invention.  



  La     fig.    1 en est une vue en plan, tandis  que  la     fig.    2 en est une coupe selon la ligne       II-II    de 1 a     fig.    1.  



  1 désigne la planche du coq du     mouvement     sur lequel le palier     pare-chocs    est, monté et  sur laquelle le coqueret 2 est maintenu au    moyen de vis 3. Autour du coqueret tourne la.  raquette 4. Coqueret et raquette ont une dé  coupure ou solution de continuité à travers  lesquelles passe un ressort 5 ondulé paral  lèlement au coq auquel il est fixé par une vis  6, et présentant, à son extrémité une bague 7  fendue et dans laquelle est. maintenu suspendu  le coussinet 8 portant le     eontre-pivot    9.  



  Le ressort 5 absorbe aussi bien les compo  santes radiales que les composantes axiales des  choc que reçoit la montre dans     laquelle    le  palier pare-chocs est monté. Ce serait aussi le  cas si ce ressort 5 reposait sur le coq sur  toute sa. longueur.



  Bumper bearing for clockwork movement balance pivot. _The bumper bearing, object of the present invention, is intended for a balance pivot of a clockwork movement rotating in a bearing. metallic. In the particular case, this pad is held freely inside the cockle by an arm making a spring and crossing both the cockpit and the rim of the racket in cutouts provided for this purpose. In this way, a whole is obtained which is capable of absorbing both the radial components and the axial components of the shocks that the watch receives and this by means of members whose minimal cost can still be borne by the selling price of movements. of the aforementioned kind.



  The appended drawing shows, by way of example, an embodiment of the bearing according to the present invention.



  Fig. 1 is a plan view thereof, while FIG. 2 is a section along the line II-II from 1 to fig. 1.



  1 designates the board of the movement cock on which the bumper bearing is mounted and on which the cockerel 2 is held by means of screws 3. Around the cockle rotates. racket 4. Coqueret and racket have a cut or solution of continuity through which passes a corrugated spring 5 parallel to the cock to which it is fixed by a screw 6, and having, at its end a split ring 7 and in which is. kept suspended the bearing 8 carrying the counter-pivot 9.



  The spring 5 absorbs both the radial components and the axial components of the shocks received by the watch in which the bumper bearing is mounted. This would also be the case if this spring 5 rested on the cock over its entire length. length.
