Description

  

      Raquetterie    pour     pièce    d'horlogerie.    La     présente    invention a pour objet une       raquetterie    pour pièce d'horlogerie, dans la  quelle le piton est. fixé à un support. monté       rotativement    sur le coq, la raquette étant  montée     rotativement    autour de ce support.  



  Cette     raquetterie    est caractérisée par un       dispositif    permettant de bloquer ledit support  de manière à l'empêcher (le tourner une foi,  que la mise au repère     est    effectuée.  



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



  La     fig.    1 est une vue en plan d'une     ra-          quetterie,    et  la     fi---.        \?    est une coupe     suivant        II-II    (le  la     fig.    1.  



  lie coq     est    désigné par 1, le     coqueret        par?.     Un support 3 portant le piton 4 est. monté       rotativement    autour du     coqueret    ?.     Autour    de  cc support est également montée     rotativement     la raquette fendue, désignée par 5, et qui  porte des goupilles 6.     1-n    excentrique 7 est  pivoté dans le coq 1.

       (-'ci    excentrique est soli  daire d'une tête     tendue   <I>Ici</I> (lui permet de     1c     faire     tourner.    Il agit sur     un    rebord     ei        lin-          drique    3a du support 3.  



  Lorsque la mise au repère du balancier  est effectuée, ce qui ne se fait que lors du  remontage de la montre et n'a plus à être mo  difié     ensuite,    l'excentrique 7 est. tourné au       iiioyen    d'un tournevis     jusqu'à    ce qu'il bloque    le     support    3 par sa     pression    contre le rebord       3a;    le     support    3 ne peut ainsi plus tourner  autour du coqueret.  



  Il est à remarquer que la raquette 5 pré  sente un chanfrein périphérique 8 contre le  quel s'appuie une portée conique 9 de la tête       7a,    ce qui maintient la raquette en place       axialement.  



      Racket for timepiece. The present invention relates to a rack for a timepiece, in which the piton is. attached to a support. rotatably mounted on the rooster, the racket being rotatably mounted around this support.



  This racket is characterized by a device making it possible to block said support so as to prevent it (turn it once, that the setting in the mark is carried out.



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



  Fig. 1 is a plan view of a rack, and the fi ---. \? is a section along II-II (fig. 1.



  lie rooster is designated by 1, the rooster by ?. A support 3 carrying the eyebolt 4 is. mounted rotatably around the cockpit ?. Around this support is also mounted rotatably the split racket, designated by 5, and which carries pins 6. 1-n eccentric 7 is pivoted in the cock 1.

       (-'ci eccentric is integral with a taut head <I> Here </I> (allows it to rotate 1c. It acts on an ei linear rim 3a of support 3.



  When the balance has been set to the mark, which is only done when the watch is wound up and does not have to be changed afterwards, the eccentric 7 is. turned using a screwdriver until it locks the support 3 by pressing it against the rim 3a; the support 3 can thus no longer rotate around the cockle.



  It should be noted that the racket 5 has a peripheral chamfer 8 against which a conical bearing 9 of the head 7a rests, which keeps the racket in place axially.

Claims

P.EVENDICATION: Rackmount for a timepiece, in which the pin is fixed to a support mounted rotatably on the cock, the racket itself being mounted rotatably around this support., Characterized by a device allowing to block the said . holder so as to prevent it from rotating after registration is completed.

SUB-CLAIMS: 1. Rack according to claim, characterized in that the locking device comprises an eccentric pivoted in the cock and acting on a cylindrical rim of said support. \ ?. Racket according to claim and. Sub-claim 1, characterized in that the racket has a peripherical chamfer against which a conical bearing surface of a control head of said eccentric rests, the whole so as to keep the racket in place axially.
