Description

  

   <Desc/Clms Page number 1> 
 Pièce d'horlogerie à seconde au centre et à remontage par masse oscillante On connaît déjà des pièces d'horlogerie à seconde au centre et à remontage par masse oscillante, dans lesquelles celle-ci tourne autour d'un axe monté au centre du mouvement et solidaire d'une planche fixée au pont du    dispositif   de remontage ; dans certaines d'entre elles ce pont présente une creusure dans laquelle est logé l'axe de la roue de seconde de manière à gagner un peu de place en hauteur. 



  On connaît d'autre part des roues de seconde dont la partie centrale est plus basse que la périphérie de manière à pouvoir être logées dans certains ensembles en prenant le moins de place possible. 



  On n'a cependant jamais combiné ces différents éléments pour loger dans la hauteur du pont de rouage à la fois la partie périphérique de la roue de seconde, le palier supérieur de celle-ci et la planche susmentionnée    ce   qui diminue la hauteur de la pièce. 



  La présente invention a précisément pour objet une pièce d'horlogerie à seconde au centre et à remontage par masse oscillante, dans laquelle la roue de seconde présente une partie centrale plus basse que sa périphérie et la masse tourne autour d'un axe monté au    centre   du mouvement et solidaire d'une planche fixée au pont du dispositif de remontage, caractérisée par une creusure circulaire pratiqué dans la face inférieure du pont de rouage et dont le centre forme une    saillie   servant de palier à l'axe de la roue de secondes, le fond de cette creusure étant percé d'une ouverture qui sert de logement à la planche mentionnée,    cette   dernière portant au-dessus de ladite    saillie,   le pivot de la masse, sa face inférieure étant au niveau de celle de la creusure. 



  Le dessin ci-annexé représente, à titre d'exemple, une forme d'exécution de l'objet de la présente invention. La    fig.   1 en est une coupe axiale. 



  Les    fig.   2 et 3 sont des plans de détails. 



  Dans ces figures, la    platine   est désignée par 1 et le pont de rouage par 2 ; entre eux est disposé le pont intermédiaire 3. Le mobile de centre 4 est monté entre ce    dernier   et la platine ; il est commandé par le barillet 5 et commande lui-même le dispositif    régu-      larisateur   par un rouage qui n'est pas représenté et dont fait partie le mobile de seconde au centre 6. Celui-ci présente une partie centrale 6a disposée plus bas qu'une partie périphérique 6b. Au-dessus du pont de rouage 2 est fixé le pont 7 du dispositif de remontage automatique. Celui-ci comprend la masse oscillante 8 à laquelle est fixé le pignon 9 commandant un rouage qui aboutit au rochet du barillet et dont le premier mobile 10 est seul représenté.

   La masse 8 tourne autour de l'axe 11 solidaire d'une planche 12    fixée   à la face inférieure du pont 7 par le moyen de vis 12a et de pieds 12b. 



  Les    fig.   2 et 3 représentent, en plan, la face inférieure du pont 2 respectivement du pont 7 ; la    fig.   1 montrant une coupe par    I-I   de la    fig.   3. 



  Dans la face inférieure du pont 2 est pratiquée une creusure circulaire 2a au centre de laquelle est ménagée une saillie 2c, qui forme    palier   pour le pivot supérieur de la roue de seconde au centre 6. En outre, dans le fond de    cette   creusure 2a est pratiquée une ouverture 2b de forme générale triangulaire. Quant à la planche 12, fixée à la partie inférieure du pont 7, elle a la même forme et se loge dans cette ouverture 2b, sa face inférieure se trouvant dans le plan de celle de la creusure 2a.

   La planche 12 porte le tenon 11 qui, avec le moyeu de la masse 8, est logé dans un dégagement 7a du pont 7. 

 <Desc/Clms Page number 2> 

 Grâce à cette disposition, la partie périphérique 6b de la roue de seconde 6, le palier supérieur 2c pour cette roue et la planche 12 se trouvent logés dans l'épaisseur du pont 2, ce qui diminue notablement la hauteur de l'ensemble.

 Timepiece with central seconds and winding by an oscillating weight We already know pieces of watchmaking with a second in the center and winding by an oscillating weight, in which the latter rotates around an axis mounted in the center of the movement and integral with a board fixed to the bridge of the winding device; in some of them, this bridge has a hollow in which the axis of the second wheel is housed so as to save a little space in height.



  On the other hand, second wheels are known, the central part of which is lower than the periphery so as to be able to be accommodated in certain assemblies while taking up as little space as possible.



  However, we have never combined these different elements to accommodate in the height of the gear bridge both the peripheral part of the second wheel, the upper bearing of the latter and the aforementioned board which reduces the height of the part. .



  The present invention specifically relates to a timepiece with a central second and winding by an oscillating weight, in which the seconds wheel has a central part lower than its periphery and the mass rotates around an axis mounted in the center. movement and integral with a board fixed to the bridge of the winding device, characterized by a circular recess made in the underside of the gear bridge and whose center forms a projection serving as a bearing for the axis of the seconds wheel, the bottom of this recess being pierced with an opening which serves as a housing for the mentioned board, the latter bearing above said projection, the pivot of the mass, its lower face being level with that of the recess.



  The accompanying drawing represents, by way of example, an embodiment of the object of the present invention. Fig. 1 is an axial section.



  Figs. 2 and 3 are detail plans.



  In these figures, the plate is designated by 1 and the gear train bridge by 2; between them is arranged the intermediate bridge 3. The center mobile 4 is mounted between the latter and the plate; it is controlled by the barrel 5 and itself controls the regulating device by a cog which is not shown and of which the central second mobile part 6. This has a central part 6a arranged lower than 'a peripheral part 6b. Above the gear bridge 2 is fixed the bridge 7 of the automatic winding device. This comprises the oscillating mass 8 to which is fixed the pinion 9 controlling a gear which ends at the ratchet of the barrel and of which the first mobile 10 is only shown.

   The mass 8 rotates around the axis 11 integral with a board 12 fixed to the underside of the bridge 7 by means of screws 12a and feet 12b.



  Figs. 2 and 3 show, in plan, the lower face of the bridge 2 respectively of the bridge 7; fig. 1 showing a section through I-I of FIG. 3.



  In the lower face of the bridge 2 is made a circular recess 2a in the center of which is formed a projection 2c, which forms a bearing for the upper pivot of the second wheel at the center 6. In addition, in the bottom of this recess 2a is made an opening 2b of generally triangular shape. As for the board 12, fixed to the lower part of the bridge 7, it has the same shape and is housed in this opening 2b, its lower face being in the plane of that of the recess 2a.

   The board 12 carries the tenon 11 which, with the hub of the mass 8, is housed in a recess 7a of the bridge 7.

 <Desc / Clms Page number 2>

 Thanks to this arrangement, the peripheral part 6b of the second wheel 6, the upper bearing 2c for this wheel and the board 12 are housed in the thickness of the bridge 2, which significantly reduces the height of the assembly.
