A reversing mechanism for automatic winding of a timepiece by an oscillating mass including a winding wheel (1) coaxially mounted with two ratchet wheels (6, 9) arranged on either face of said winding wheel which bears on each of its faces at least one pawl (14a to 14d) loaded by a spring (15a to 15d) and cooperating respectively with one of the ratchet wheels (6, 9), the assembly thus formed being inserted between the kinematic chain interposed between the oscillating mass (5) and the mainspring barrel of the timepiece, the pawls (14a to 14d) assigned to the transmission of the rotation of said mass (5) being articulately mounted respectively on pivot members (13) fixed to said winding wheel (1), characterized in that the pivot member (13) bearing the pawl (14a or 14b) assigned to one of the directions of rotation of the mass serves at the same time as anchoring member for the spring (15a or 15b) which loads the pawl (14c or 14d) assigned to transmit the other direction of rotation of said mass.

Description

La présente invention concerne les dispositifs de remontage automatique par masse oscillante des pièces d'horlogerie.The present invention relates to automatic winding devices by oscillating weight of timepieces.

Plus précisément, l'invention a trait à un mécanisme inverseur pour un tel dispositif de remontage automatique.More specifically, the invention relates to a reversing mechanism for such an automatic winding device.

De façon classique, le remontage automatique d'une pièce d'hor­logerie est assuré par un ensemble comprenant une masse oscillante pivotante qui est couplée au barillet du ressort moteur par l'in­termédiaire d'un mécanisme inverseur afin que la masse puisse délivrer l'énergie cinétique pour le remontage du ressort quel que soit son sens de rotation.Conventionally, the automatic winding of a timepiece is ensured by an assembly comprising a pivoting oscillating mass which is coupled to the mainspring barrel by means of an reversing mechanism so that the mass can deliver energy kinetics for winding the spring regardless of its direction of rotation.

Parmi les types de mécanismes inverseurs les plus répandus, on peut compter celui qui comprend, pour chaque sens de rotation de la masse oscillante, une roue à rochet et un cliquet chargé par un ressort. Les cliquets et leurs ressorts associés sont portés par une roue d'armage commune qui est couplée alternativement au train démultiplicateur de remontage par l'intermédiaire des cliquets respectifs agissant sur les roues à rochet.Among the most widespread types of reversing mechanisms, one can count that which includes, for each direction of rotation of the oscillating mass, a ratchet wheel and a pawl loaded by a spring. The pawls and their associated springs are carried by a common winding wheel which is alternately coupled to the winding reduction gear via the respective pawls acting on the ratchet wheels.

Un tel agencement est décrit dans le brevet CH-344.370. Dans ce cas, la roue d'armage porte un cliquet sur chacune de ses faces, tandis que les roues à rochet sont montées de part et d'autre de cette roue d'armage sur un axe de pivotement commun. Le cliquets sont articulés sur la roue d'armage au moyen de tenons fixés dans celle-ci. Ce brevet ne précise pas cependant comment les ressorts chargeant les cliquets sont agencés sur la roue d'armage.Such an arrangement is described in patent CH-344,370. In this case, the winding wheel carries a pawl on each of its faces, while the ratchet wheels are mounted on either side of this winding wheel on a common pivot axis. The pawls are articulated on the winding wheel by means of studs fixed therein. This patent does not however specify how the springs loading the pawls are arranged on the winding wheel.

Dans un autre mécanisme connu, décrit dans le CH 348.922, il est prévu un plateau porte-cliquets associé à un anneau de montage coaxial au plateau mais espacé de celui-ci. Chaque cliquet est monté articulé sur un pivot serré entre le plateau et l'anneau et coopère avec un ressort ancré dans le plateau au moyen d'un tenon spécia­lement prévu pour cet ancrage.In another known mechanism, described in CH 348.922, there is provided a pawl plate associated with a mounting ring coaxial with the plate but spaced therefrom. Each pawl is mounted articulated on a pivot tightened between the plate and the ring and cooperates with a spring anchored in the plate by means of a pin specially provided for this anchoring.

L'invention a pour but de fournir un mécanisme inverseur du type général évoqué ci-dessus, ayant une construction simplifiée, de manière à en rendre le montage aussi aisé que possible.The object of the invention is to provide a reversing mechanism of the general type mentioned above, having a simplified construction, so as to make assembly as easy as possible.

L'invention a donc pour objet un mécanisme inverseur pour dispositif de remontage automatique par masse oscillante d'une pièce d'horlogerie, comportant une roue d'armage montée coaxialement à deux roues à rochet disposées de part et d'autre de cette roue qui porte sur chacune de ses faces au moins un cliquet chargé par un ressort et coopérant respectivement avec l'une des roues à rochet, l'ensemble ainsi formé étant inséré entre la chaîne cinématique interposée entre la masse oscillante et le barillet du ressort moteur de la pièce d'horlogerie, les cliquets affectés à la trans­mission de la rotation de ladite masse étant montés articulés respectivement sur des organes de pivotement solidaires de ladite roue d'armage, caractérisé en ce que l'organe de pivotement portant le cliquet affecté à l'un des sens de rotation de la masse sert en même temps d'organe d'ancrage pour le ressort qui charge le cliquet affecté à la transmission de l'autre sens de rotation de ladite masse.The invention therefore relates to a reversing mechanism for an automatic winding device by oscillating weight of a timepiece, comprising a winding wheel mounted coaxially with two ratchet wheels arranged on either side of this wheel which carries on each of its faces at least one pawl loaded by a spring and cooperating respectively with one of the ratchet wheels, the assembly thus formed being inserted between the kinematic chain interposed between the oscillating mass and the barrel of the mainspring of the timepiece, the pawls assigned to the transmission of the rotation of said mass being hinged respectively on pivoting members secured to said winding wheel, characterized in that the pivoting member carrying the pawl assigned to the one of the directions of rotation of the mass serves at the same time as an anchoring member for the spring which loads the pawl assigned to the transmission of the other direction of rotation of said mass.

On obtient ainsi un mécanisme inverseur dans lequel chaque cliquet est monté en commun avec un ressort qui charge l'autre cliquet, sur un seul et même organe de pivotement. Il en résulte non seulement un gain de place mais également une facilité de montage appréciable.There is thus obtained a reversing mechanism in which each pawl is mounted in common with a spring which loads the other pawl, on a single pivot member. This results not only in saving space but also in appreciable ease of assembly.

The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the appended drawings in which:
  • - Figure 1 is a sectional view in external view of a reversing mechanism according to the invention;
  • - Figure 2 is a sectional view, on a larger scale, of the winding wheel and its associated members incorporated in the mechanism according to the invention;

En se référant aux figures, on voit que la roue d'armage 1 du mécanisme inverseur suivant l'invention comporte une planche 1a et un canon 1b qui est engagé librement sur un axe de pivotement 2. Ce dernier est monté à rotation entre une platine 3a et un pont 3b de la pièce d'horlogerie. La planche 1a de la roue d'armage 1 comporte une couronne 1c qui engrène avec le pignon 4 solidaire en rotation de la masse oscillante 5.Referring to the figures, it can be seen that the winding wheel 1 of the reversing mechanism according to the invention comprises a plate 1a and a barrel 1b which is freely engaged on a pivot axis 2. The latter is mounted for rotation between a plate 3a and a bridge 3b of the timepiece. The plate 1a of the winding wheel 1 comprises a crown 1c which meshes with the pinion 4 integral in rotation with the oscillating mass 5.

L'axe 2 forme un mobile avec une première roue à rochet 6 et une roue de transmission 7 engrènant avec un mobile 8 d'un train réduc­teur menant au barillet (non représenté) du ressort moteur de la pièce d'horlogerie, conformément à un agencement qui est bien connu des spécialistes.Axis 2 forms a mobile with a first ratchet wheel 6 and a transmission wheel 7 meshing with a mobile 8 of a reduction gear leading to the barrel (not shown) of the mainspring of the timepiece, in accordance with a arrangement which is well known to specialists.

Une deuxième roue à rochet 9, disposée contre la face de la planche 1a de la roue d'armage 1 opposée à la première roue à rochet 6, est calée sur un pignon de transmission 10 monté à rotation libre autour du canon 1b de la roue d'armage 1.A second ratchet wheel 9, disposed against the face of the board 1a of the winding wheel 1 opposite to the first ratchet wheel 6, is wedged on a transmission pinion 10 mounted with free rotation around the barrel 1b of the wheel armament 1.

Le pignon 10 est en prise avec une roue intermédiaire 11 engré­nant également avec le mobile 8 du train réducteur. Il est à noter que la vue en coupe de la figure 1 correspond à la ligne de coupe brisée apparaissant sur la figure 7.The pinion 10 is engaged with an intermediate wheel 11 also meshing with the mobile 8 of the reduction gear. It should be noted that the sectional view in FIG. 1 corresponds to the broken section line appearing in FIG. 7.

La figure 6 montre que la planche 1a de la roue d'armage 1 est percée de trous 12 situés respectivement à 3, 6, 9 et 12 heures (figure 3), chaque trou étant délimité par deux portions de bord opposées rectilignes 12a réunies par deux portions de bord courbes 12b.FIG. 6 shows that the plate 1a of the winding wheel 1 is pierced with holes 12 located respectively at 3, 6, 9 and 12 o'clock (FIG. 3), each hole being delimited by two opposite straight edge portions 12a joined by two curved edge portions 12b.

Chacun de ces trous 12 reçoit un rivet 13 servant au montage sur la roue d'armage 1 d'un ensemble formé respectivement par des cliquets 14a à 14d et de ressorts 15a à 15d.Each of these holes 12 receives a rivet 13 used for mounting on the winding wheel 1 of an assembly formed respectively by pawls 14a to 14d and springs 15a to 15d.

Chaque rivet 13 comporte une tige 16 (figures 4 et 5) pourvue à l'une de ses extrémités d'une collerette 17 dont un segment périphé­rique est découpé et qui présente ainsi un bord rectiligne 18.Each rivet 13 comprises a rod 16 (FIGS. 4 and 5) provided at one of its ends with a flange 17, a peripheral segment of which is cut out and which thus has a straight edge 18.

Une portion cylindrique de faible hauteur 19 de la tige 16, située près de la collerette 17, sert de portée d'articulation au cliquet 14a à 14d engagé sur le rivet 13 considéré.A cylindrical portion 19 of low height of the rod 16, located near the flange 17, serves as an articulation bearing for the pawl 14a to 14d engaged on the rivet 13 considered.

Le reste de la tige 16 présente deux méplats 20 diamétralement opposés, s'ajustant sur les bords rectilignes 12a des trous 12 de la roue d'armage 1.The rest of the rod 16 has two diametrically opposite flats 20, fitting on the straight edges 12a of the holes 12 of the winding wheel 1.

On voit que dans le mode de réalisation décrit, chaque roue à rochet 6 et 9 coopère avec deux cliquets respectivement 14a, 14b et 14c, 14d auxquels sont associés les ressorts 15c, 15d et 15a, 15b, respectivement, étant entendu que le cliquet (14a, par exemple) affecté à une à roue rochet donnée (6, par exemple) est monté articulé sur le rivet 13 qui supporte en même temps le ressort (15a, par exemple) qui charge le cliquet (14c, par exemple) agissant sur l'autre roue à rochet (9, par exemple).It can be seen that in the embodiment described, each ratchet wheel 6 and 9 cooperates with two pawls respectively 14a, 14b and 14c, 14d with which the springs 15c, 15d and 15a, 15b are associated, respectively, it being understood that the pawl ( 14a, for example) assigned to a given ratchet wheel (6, for example) is mounted articulated on the rivet 13 which at the same time supports the spring (15a, for example) which loads the pawl (14c, for example) acting on the other ratchet wheel (9, for example).

Toutefois, il n'est pas indispensable que deux cliquets agissent simultanément sur une même roue à rochet. Dans une version simpli­fiée du mécanisme inverseur suivant l'invention, on pourrait se contenter de ne prévoir que les ensembles cliquet-ressort 14a, 15a et 14c, 15c, ou bien les ensembles cliquet-ressort 14b, 15b et 14d, 15d.However, it is not essential that two pawls act simultaneously on the same ratchet wheel. In a simplified version of the reversing mechanism according to the invention, one could be satisfied with providing only the pawl-spring assemblies 14a, 15a and 14c, 15c, or else the pawl-spring assemblies 14b, 15b and 14d, 15d.

L'avantage de l'agencement double, visible sur la figure 3, consiste en ce que l'on peut décaler les pointes des cliquets agissant sur une même roue à rochet d'une demi-dent ce qui réduit de moitié la course minimale de la masse oscillante requise pour obtenir une action d'armage, par rapport au cas où un seul cliquet par roue à rochet est prévu.The advantage of the double arrangement, visible in FIG. 3, is that the tips of the pawls acting on the same ratchet wheel can be offset by half a tooth, which reduces the minimum stroke by half. the oscillating mass required to obtain a winding action, compared to the case where only one pawl per ratchet wheel is provided.

Cependant, quelle que soit la solution adoptée, grâce au fait que chaque rivet reçoit à la fois un cliquet et un ressort, non seulement le mécanisme est plus simple, prend moins de place et requiert un nombre d'usinages et de pièces réduits, mais on simpli­fie également le montage du mécanisme.However, whatever the solution adopted, thanks to the fact that each rivet receives both a pawl and a spring, not only is the mechanism simpler, takes up less space and requires a reduced number of machining operations and parts, but the assembly of the mechanism is also simplified.

La découpe pratiquée sur la collerette 17 de chaque rivet 13 pour former le bord 18 facilite l'engagement de la lame élastique 25 en dessous de cette collerette et en évite une trop grande déforma­tion pendant cette opération.The cutting made on the flange 17 of each rivet 13 to form the edge 18 facilitates the engagement of the elastic blade 25 below this flange and avoids excessive deformation during this operation.

Le fonctionnement du mécanisme inverseur apparaît sur la figure 7.The operation of the reversing mechanism is shown in Figure 7.

La masse oscillante 5 étant entraînée dans les deux sens, la roue d'armage 1 la suit dans ces mouvements en déplaçant les cli­quets 14a à 14d.The oscillating mass 5 being driven in both directions, the winding wheel 1 follows it in these movements by moving the pawls 14a to 14d.

Si le sens correspond à la flèche F1 de la figure 7, les cli­quets 14a et 14b s'engagent dans la denture de la roue à rochet 6, tandis que les cliquets 14c et 14d se dérobent par rapport à la roue à rochet 9. La roue 6 étant couplée à la roue 7, la roue 8 est entraînée dans le sens des flèches F3.If the direction corresponds to the arrow F1 in FIG. 7, the pawls 14a and 14b engage in the teeth of the ratchet wheel 6, while the pawls 14c and 14d slide away from the ratchet wheel 9. The wheel 6 being coupled to wheel 7, wheel 8 is driven in the direction of the arrows F3.

Si, au contraire, la roue d'armage 1 tourne dans le sens de la flèche F2, ce sont les cliquets 14c et 14d qui s'engagent dans la denture de la roue à rochet 9, tandis que les cliquets 14a et 14b se dérobent par rapport à la roue à rochet 6. La roue 9 est calée sur le pignon 10 qui entraîne alors la roue 8 dans le sens des flèches F3 grâce à la roue intermédiaire 11.If, on the contrary, the winding wheel 1 rotates in the direction of the arrow F2, it is the pawls 14c and 14d which engage in the teeth of the ratchet wheel 9, while the pawls 14a and 14b escape with respect to the ratchet wheel 6. The wheel 9 is wedged on the pinion 10 which then drives the wheel 8 in the direction of the arrows F3 thanks to the intermediate wheel 11.

La tige 16 de chaque rivet 13 comporte à son extrémité libre un évidement conique 21 qui est coaxial au rivet. Dans sa position montée, chaque rivet 13 emprisonne un cliquet 14a à 14d entre sa collerette 17 et la face en regard de la planche 1a. Chaque cliquet comporte à cet effet une portion d'articulation 22 s'ajustant sur la portion cylindrique 19 du rivet correspondant. Il comporte également un talon actif 23 qui coopère avec la roue à rochet 6 ou 9 se trouvant située du même côté de la planche 1a.The rod 16 of each rivet 13 has at its free end a conical recess 21 which is coaxial with the rivet. In its mounted position, each rivet 13 traps a pawl 14a to 14d between its flange 17 and the opposite face of the board 1a. Each pawl has for this purpose an articulation portion 22 which adjusts to the cylindrical portion 19 of the corresponding rivet. It also includes an active heel 23 which cooperates with the ratchet wheel 6 or 9 located on the same side of the board 1a.

L'extrémité de chaque rivet opposée à la collerette 17 dépasse de la planche 1a d'une certaine hauteur pour recevoir la portion de fixation 24 d'un ressort 15a à 15d à partir de laquelle s'étend une lame élastique active 25 coopérant avec le cliquet 14a à 14d conju­gué se trouvant à la même face de la planche 1a. L'extrémité libre de chaque lame élastique active 25 est en appui contre un bord rectiligne 26 ménagé sur la portion d'articulation 22 du cliquet 14a à 14d avec lequel elle coopère.The end of each rivet opposite the flange 17 protrudes from the board 1a by a certain height to receive the fixing portion 24 of a spring 15a to 15d from which extends an active elastic blade 25 cooperating with the pawl 14a to 14d conjugate located on the same face of the board 1a. The free end of each active elastic blade 25 bears against a straight edge 26 formed on the articulation portion 22 of the pawl 14a to 14d with which it cooperates.

La portion de fixation 24 de chaque ressort 15a à 15d comporte un trou 27 de même forme que les trous 12 de la planche 1a. Les ressorts sont ainsi bloqués en rotation sur leur rivet correspondant tandis qu'ils le sont également axialement grâce à une déformation vers l'extérieur de l'extrémité de la tige de chaque rivet, opérée après montage de chaque ensemble sur la planche 1a. Cette opération de déformation fait office de rivetage.The fixing portion 24 of each spring 15a to 15d has a hole 27 of the same shape as the holes 12 of the board 1a. The springs are thus locked in rotation on their corresponding rivet while they are also axially locked by a deformation towards the outside of the end of the rod of each rivet, operated after mounting of each assembly on the board 1a. This deformation operation acts as riveting.
