Description

  

  Encliquetage, notamment pour mobiles dentés de mouvements d'horlogerie.    L'invention a pour objet un     encliquetage,     plus particulièrement mais non exclusivement  pour mobiles dentés de mouvements de montres  et de mouvements d'horlogerie.  



  Cet -encliquetage comprend selon     l'inven,          tion,    un cliquet pivoté sur un support et pos  sédant une saillie engagée dans une ouver  ture du support, entre une partie rigide et  une partie flexible de ce dernier, cette partie  flexible étant venue de fabrication avec le  support et constituant le ressort de cliquet.  



  Le dessin annexé montre, à titre d'exemple,  un encliquetage de rochet de barillet de montre.  La     fig.    1 est une vue en plan, tandis que  les     fig.    2 et 3 montrent chacune une coupe  suivant la ligne     II-II        resp.        III-III    de la       fig.    1.  



  Sur la mince platine (pont) 4 du bâti  d'un mouvement de montre est monté le ro  chet de barillet 5 (représenté partiellement,  en traits mixtes) ajusté sur un carré de l'arbre  de barillet (non représenté). La platine 4 pré  sente sur sa face interne une     creusure    4' pour  le tambour de barillet, de sorte que la partie    de la platine,     sur    laquelle repose le rochet 5,  est relativement mince. Cette partie relative  ment mince est percée d'une ouverture 6 en  <B>V</B> de manière à former dans la platine une  languette 7 latéralement flexible et constitu  ant le ressort de rappel du     cliquet    de retenue  8 du rochet 5.  



  Ce cliquet, appelé     "masse"    en terminologie  horlogère, est monté à pivot sur la platine 4,  au moyen d'une vis à portée 9. Il possède  une dent 10 destinée à coopérer avec la den  ture du rochet de barillet. La dent 10 pré  sente sur sa face interne une saillie 10' qui  est engagée dans l'ouverture 6 de la platine  4, entre le bord rigide de l'ouverture et l'ex  trémité de la languette 7. La saillie 10' bu  tant contre le bord de l'ouverture 6, la dent  le du cliquet empêche le rochet de tourner  en sens rétrograde. Par contre, lorsque le ro  chet tourne suivant le sens de remontage, la  dent 10 du cliquet est écartée de la denture  du rochet et fait fléchir la languette 7 par la .  saillie 10'.

   Mais, aussitôt que le rochet cesse  d'être     entrainé,    la languette flexible ramène      la dent 10 à sa position initiale détermi  née par la saillie 10' butant contre le bord  de l'ouverture 6.  



  La saillie 10' pourrait être constituée par  une goupille, un doigt ou une vis adaptée  au     cliquet.     



  L'invention est également applicable     aux     encliquetages comportant un cliquet d'impul  sion pour imprimer un mouvement de rotation,  toujours dans le même sens, à une roue dentée.



  Snap-fastening, in particular for toothed moving parts of watch movements. The object of the invention is a snap-fastening, more particularly but not exclusively for toothed moving parts of watch movements and clock movements.



  This -clipping comprises according to the invention, a pawl pivoted on a support and posing a protrusion engaged in an opening of the support, between a rigid part and a flexible part of the latter, this flexible part being manufactured with the support and constituting the pawl spring.



  The accompanying drawing shows, by way of example, a ratchet catch of a watch barrel. Fig. 1 is a plan view, while FIGS. 2 and 3 each show a section along the line II-II resp. III-III of fig. 1.



  On the thin plate (bridge) 4 of the frame of a watch movement is mounted the barrel rock 5 (shown partially, in phantom lines) fitted to a square of the barrel shaft (not shown). The plate 4 has on its internal face a recess 4 'for the barrel drum, so that the part of the plate, on which the ratchet 5 rests, is relatively thin. This relatively thin part is pierced with an opening 6 in <B> V </B> so as to form in the plate a laterally flexible tongue 7 and constituting the return spring of the retaining pawl 8 of the ratchet 5.



  This pawl, called a “mass” in horological terminology, is pivotally mounted on the plate 4, by means of a bearing screw 9. It has a tooth 10 intended to cooperate with the toothing of the barrel ratchet. The tooth 10 has on its internal face a projection 10 'which is engaged in the opening 6 of the plate 4, between the rigid edge of the opening and the end of the tongue 7. The projection 10' bu so against the edge of the opening 6, the tooth 1c of the pawl prevents the ratchet from turning in a retrograde direction. On the other hand, when the rocket turns in the winding direction, the tooth 10 of the pawl is moved away from the teeth of the ratchet and causes the tongue 7 to bend through the. projection 10 '.

   But, as soon as the ratchet ceases to be driven, the flexible tongue returns the tooth 10 to its initial position determined by the projection 10 'abutting against the edge of the opening 6.



  The projection 10 'could be constituted by a pin, a finger or a screw adapted to the pawl.



  The invention is also applicable to snap-fastenings comprising an impulse pawl for imparting a rotational movement, always in the same direction, to a toothed wheel.

REVENDICATION Encliquetage, notamment pour mobiles dentés de mouvements d'horlogerie, caractérisé en ce qu'il comprend un cliquet pivoté sur un support et possédant une saillie engagée dans une ouverture du support, entre une partie rigide et une partie flexible de ce dernier, cette partie flexible étant venue de fabrication avec le support et constituant le ressort de cliquet. SOUS-REVENDICATION: CLAIM Snap-fastening, in particular for toothed moving parts of clockwork movements, characterized in that it comprises a pawl pivoted on a support and having a projection engaged in an opening of the support, between a rigid part and a flexible part of the latter, this flexible part having come from manufacture with the support and constituting the pawl spring. SUB-CLAIM: Encliquetage selon la revendication, carac= térisé en ce que le cliquet (8) et le mobile denté (5) coopérant avec le cliquet sont mon tés sur une mince platine (4) dans laquelle est ménagée par découpage une languette flexible (7) constituant le ressort de cliquet des tiné à agir sur une saillie latérale (10') de la dent de retenue (10) du cliquet. Latching according to claim, charac = terized in that the pawl (8) and the toothed mobile (5) cooperating with the pawl are mounted on a thin plate (4) in which is formed by cutting a flexible tab (7) constituting the pawl spring of the tines to act on a side projection (10 ') of the retaining tooth (10) of the pawl.
