Description

  

      b1écanisme    d'embrayage de chronographe.    Le réglage du mécanisme d'embrayage  de chronographe est     difficultueux    avec les  moyens connus jusqu'à ce jour.  



  L'invention a pour objet un mécanisme  d'embrayage     -des    axes de chronographe, ca  ractérisé par le fait qu'au     moins    un des  organes     intermédiaires        transmettant    le mou  vement de la roue à colonne sur l'axe du  chronographe est réglable dans sa fonction  dans. le but     clé        permettre    le réglage -de la  pression axiale d'embrayage de l'axe de chro  nographe.  



       Le    demie ci-joint montre, en     coupe,    à  titre d'exemple, une partie d'une forme d'exé  cution de l'objet de l'invention.  



       Le    mécanisme comporte un axe de chro  nographe 1, mobile     axialement,    muni du       coeur    2, d'un plateau 3 et du disque d'em  brayage 4. Le pignon de chronographe 5,  muni du disque d'entraînement 22, est monté  fou sur l'axe de chronographe 1 et est en  traîné par la petite moyenne 23.  



  La pression axiale d'embrayage exercée  sur l'axe 1 du chronographe est réglée par    une vis 15 agissant sur le ressort d'em  brayage 9, qui est commandé, par     l'intermé-          -diaire    de son appendice 12, par un levier  d'embrayage 21 coopérant avec la roue à co  lonne.  



  Le ressort d'embrayage 9 est muni d'un  autre appendice 11 qui sert à commander le       ressort    de débrayage 17, lequel, dans la posi  tion d'arrêt, débraye l'axe de chronographe 1  du     pignon    5 par     l'intermédiaire    -du plateau  3. Dans la position d'arrêt, cet organe 17  freine l'axe -de chronographe 1 de telle façon  qu'il empêche l'axe de chronographe     portant          l'aiguille    et le     coeur        inéquilibrés    de tourner  sous l'action d'un choc. La vis 20 permet de  régler le jeu axial du pignon 5 par l'inter  médiaire du ressort 18.  



  Il est évident que dans l'ensemble -des  organes     intermédiaires    de commande de l'em  brayage au     moins    un autre organe que le  ressort d'embrayage peut être exécuté ré  glable mécaniquement et servir à l'ajuste  ment de la position d'embrayage de l'axe de           ehronograplie,        provoquant        l'embrayage    de<B>et,</B>  dernier.  



  Le dispositif décrit permet ainsi de régler  la. force d'embrayage même pendant la     mai-          t,    =ans qu'aucun     df@montage        -soit        nécessaire.  



      b1 chronograph clutch mechanism. The adjustment of the chronograph clutch mechanism is difficult with the means known to date.



  The object of the invention is a clutch mechanism -of the chronograph axes, characterized in that at least one of the intermediate members transmitting the movement of the column wheel on the chronograph axis is adjustable in its function. in. the key aim is to allow adjustment of the axial clutch pressure of the chronograph shaft.



       The attached half shows, in section, by way of example, a part of an embodiment of the object of the invention.



       The mechanism comprises a chronograph axis 1, movable axially, provided with the core 2, a plate 3 and the clutch disc 4. The chronograph pinion 5, provided with the drive disc 22, is mounted idle on the chronograph axis 1 and is trailed by the small medium 23.



  The axial clutch pressure exerted on the axis 1 of the chronograph is regulated by a screw 15 acting on the clutch spring 9, which is controlled, by the intermediary of its appendix 12, by a lever d 'clutch 21 cooperating with the column wheel.



  The clutch spring 9 is provided with another appendage 11 which serves to control the disengaging spring 17, which, in the stop position, disengages the chronograph axis 1 from the pinion 5 by means of -du plate 3. In the stop position, this member 17 brakes the chronograph axis 1 in such a way that it prevents the chronograph axis carrying the unbalanced needle and heart from rotating under the action of a shock. The screw 20 makes it possible to adjust the axial play of the pinion 5 by means of the spring 18.



  It is obvious that in all the intermediate clutch control members at least one member other than the clutch spring can be made mechanically adjustable and serve to adjust the clutch position of the clutch. the chronograplie axis, causing the <B> and, </B> last clutch.



  The device described thus makes it possible to adjust the. clutch force even during start-up, = no df @ assembly is necessary.

REVENDICATION Mécanisme d'embrayage de chronographe, caractérisé par le fait qu'au moins un des organes intermédiaires transmettant le mou vement de la roue à colonne sur l'axe de chro nographe est réglable dans sa fonction dans le but de permettre le réglage de la pression axiale d'embrayage de l'axe de chronographe. CLAIM Chronograph clutch mechanism, characterized by the fact that at least one of the intermediate members transmitting the movement of the column wheel on the chronograph axis is adjustable in its function in order to allow the adjustment of the axial clutch pressure of the chronograph axis. SOUS-REVENDICATIONS: 1 Mécanisme suivant la revendication, carac térisé en outre par le fait que l'organe de commande de l'embrayage qui abaisse l'axe de chronographe dans sa position d'em brayage commande les fonctions de l'or gane de commande de débrayage. lequel, dans la position d'arrêt du chronographe, bloque l'axe de chronographe. \? Mécanisme suivant la revendication et la sous-revendication 1, caractérisé en outre par le fait qu'un organe réglable mécani quement sert à régler le jeu axial du pi gnon de chronographe. SUB-CLAIMS: 1 Mechanism according to claim, further charac terized by the fact that the clutch control member which lowers the chronograph axis into its clutch position controls the functions of the control organ. clutch control. which, in the stop position of the chronograph, blocks the chronograph axis. \?
