Description

  

   <Desc/Clms Page number 1> 
 Mouvement de montre à remontage automatique Dans une montre à remontage automatique, le cliquet destiné à retenir le rochet de barillet n'a sa raison d'être que lorsque le mécanisme d'automatique est enlevé. Lorsque le mécanisme d'automatique est en place, le rochet, retenant le ressort armé, est bloqué par l'intermédiaire des roues et des cliquets disposés dans le mécanisme même d'automatique. Le cliquet habituel du mouvement représente, à ce moment, un frottement supplémentaire que la masse doit vaincre pour effectuer le remontage.

   Le but de la présente invention est de supprimer ce frottement ; à cet effet le cliquet du rochet de barillet comprend une partie susceptible, en coopération avec un élément fixe du mécanisme    d'auto-      rnatique,   de maintenir ledit cliquet hors de la trajectoire des dents du rochet de barillet lorsque ledit élément fixe est en place dans le mouvement. Le dessin représente une forme d'exécution de l'objet de l'invention donnée à titre d'exemple. 



  La    fig.   1 représente partiellement le mouvement à pont supérieur d'automatique enlevé ; et la    fig.   2 la même partie du mouvement lorsque ce pont est mis en place. 



  La    fig.   3 est une coupe par    III-III   de la    fig.   2. Dans la vue    partielle   du mouvement de la    fig.   1, on voit le rochet de barillet en 1, avec son cliquet 2 pivotant autour de la vis 3 et maintenu en prise avec les dents du rochet par l'action du    ressort   4. 



  Ceci correspond à la disposition habituelle d'un tel cliquet. Mais ici, le cliquet présente un appendice 5 constitué par une partie relevée à angle droit par    rapport   à son plan, comme cela ressort de la coupe de la    fig.   3. Cet appendice est destiné, en coopération avec le pont supérieur d'automatique, à maintenir le    cli-      quet   dans une position amenant son bec hors de la trajectoire des dents du rochet de barillet. Cette position est représentée à la    fig.   2, où le pont supérieur d'automatique 6 est mis en place et maintenu notamment au moyen de la vis 7. 



  Pour pouvoir le mettre en place, on a toutefois été obligé de déplacer le cliquet 2 en position inactive, c'est-à-dire avec son bec hors de la trajectoire des dents du rochet, ceci en raison de l'appendice 5 qui, en position de fonctionnement du cliquet s'opposerait à la mise en place du pont d'automatique 6. 



  Comme cela ressort donc des    fig.   2 et 3, le pont supérieur d'automatique 6 une fois mis en place, l'appendice 5 du cliquet reste à l'appui contre ce    dernier,   immobilise ce cliquet et l'empêche d'exercer sa fonction    normale.   Le    cliquet   est donc placé sous la dépendance d'un élément fixe du mécanisme d'automatique, de telle sorte que lorsque ledit élément étant en place dans le mouvement, il n'y a plus engrènement possible entre ce cliquet et le rochet de    barillet,   le remontage automatique pouvant alors s'effectuer librement, sans rencontrer la résistance supplémentaire résultant de la fonction de ce cliquet.

 Self-winding watch movement In a self-winding watch, the pawl intended to retain the barrel ratchet is only necessary when the automatic mechanism is removed. When the automatic mechanism is in place, the ratchet, retaining the armed spring, is blocked by means of the wheels and pawls arranged in the automatic mechanism itself. The usual pawl of the movement represents, at this moment, an additional friction that the mass must overcome to carry out the winding.

   The aim of the present invention is to eliminate this friction; for this purpose, the pawl of the barrel ratchet comprises a part capable, in cooperation with a fixed element of the automatic mechanism, of maintaining said pawl out of the path of the teeth of the barrel ratchet when said fixed element is in place in movement. The drawing represents an embodiment of the object of the invention given by way of example.



  Fig. 1 partially shows the movement with the automatic upper bridge removed; and fig. 2 the same part of the movement when this bridge is in place.



  Fig. 3 is a section through III-III of FIG. 2. In the partial view of the movement of FIG. 1, we see the barrel ratchet at 1, with its pawl 2 pivoting around screw 3 and held in engagement with the teeth of the ratchet by the action of spring 4.



  This corresponds to the usual arrangement of such a pawl. But here, the pawl has an appendage 5 formed by a part raised at a right angle to its plane, as is apparent from the section of FIG. 3. This appendage is intended, in cooperation with the automatic upper deck, to maintain the pawl in a position bringing its nose out of the path of the teeth of the barrel ratchet. This position is shown in fig. 2, where the automatic upper deck 6 is put in place and held in particular by means of the screw 7.



  To be able to put it in place, however, we had to move the pawl 2 in the inactive position, that is to say with its nose out of the path of the ratchet teeth, this because of appendix 5 which, in the operating position of the pawl would oppose the installation of the automatic bridge 6.



  As therefore emerges from FIGS. 2 and 3, the upper automatic deck 6 once in place, the appendage 5 of the pawl rests against the latter, immobilizes this pawl and prevents it from exercising its normal function. The pawl is therefore placed under the control of a fixed element of the automatic mechanism, so that when said element is in place in the movement, there is no longer any possible engagement between this pawl and the barrel ratchet, the automatic winding can then be carried out freely, without encountering the additional resistance resulting from the function of this pawl.

REVENDICATION Mouvement de montre à remontage automatique, caractérisé en ce que le cliquet de son rochet de barillet comprend une partie susceptible, en coopération avec un élément fixe du mécanisme d'automatique, de maintenir ledit cliquet hors de la trajectoire des dents du rochet lorsque ledit élément fixe est en place dans le mouvement. SOUS-REVENDICATION Mouvement selon la revendication, caractérisé en ce que le cliquet présente un appendice conformé et disposé de façon à buter contre le pont supérieur d'automatique, position dans laquelle il est retenu hors de la trajectoire des dents du rochet. CLAIM Self-winding watch movement, characterized in that the pawl of its barrel ratchet comprises a part capable, in cooperation with a fixed element of the automatic mechanism, of keeping said pawl out of the path of the ratchet teeth when said fixed element is in place in the movement. SUB-CLAIM Movement according to claim, characterized in that the pawl has an appendage shaped and arranged so as to abut against the upper automatic bridge, a position in which it is retained out of the path of the teeth of the ratchet.
