Abstract

The various pivoting members-setting-lever (3), rocker lever (14) and correction lever (16)-of a setting mechanism having a setting stem (2) are held in place and pivoted by means of a metal bridge (90) an arm (9) of which forms the setting-lever spring. The setting-lever, the rocker lever and the correction lever are interposed between the plate (1, 10, 11) of the movement and the bridge which not only provides for holding them in position but also provides for pivoting thereof. For that purpose, these three pivoting members each carry an arbor (4, 15, 17), which is fitted thereto and which has two end sections (4a, 15a, 17a; 21) projecting outside of said pivoting member. One of these end sections (21) engages without appreciable clearance into a corresponding hole (101) in the bridge and the other end (4a, 15a, 17a) is located with substantial clearance in a corresponding hole (20) in the plate and serves for the prepositioning of said pivoting element on said plate.

Description

La présente invention a pour objet les pièces d'horlogerie ayant un mécanisme de commande comportant des éléments montés pivotants sur un bâti. L'invention concerne, plus particulièrement, une pièce d'horlogerie de ce type équipée d'un pont de mécanisme qui est fixé sur la platine et qui sert de palier de pivotement pour au moins l'un de ces éléments pivotants.The present invention relates to timepieces having a control mechanism comprising elements pivotally mounted on a frame. The invention relates, more particularly, to a timepiece of this type equipped with a mechanism bridge which is fixed on the plate and which serves as a pivot bearing for at least one of these pivoting elements.

Ce mécanisme de commande comprend habituellement une tige montée rotative et axialement coulissante sur un bâti, un pignon coulant monté sur la tige et des éléments pivotants formant un mécanisme de liaison servant à relier cinématiquement, en translation axiale, la tige et le pignon coulant, ainsi qu'à déterminer plusieurs positions axiales stables de la tige et du pignon coulant. Ces éléments pivotants comprennent le plus souvent une tirette coopérant avec un ressort-sautoir, et une bascule agissant sur le pignon coulant.This control mechanism usually comprises a rod mounted to rotate and axially sliding on a frame, a sliding pinion mounted on the rod and pivoting elements forming a connecting mechanism used to kinematically connect, in axial translation, the rod and the sliding pinion, as well than to determine several stable axial positions of the rod and the sliding pinion. These pivoting elements usually include a puller cooperating with a jumper spring, and a rocker acting on the sliding pinion.

D'un façon générale, quelle que soient la nature des éléments pivotants utilisés dans le mécanisme de commande de la pièce d'horlogerie, il importe que les positions relatives des axes de pivotement de ces éléments pivotants soient maintenues avec une grande précision.In general, whatever the nature of the pivoting elements used in the control mechanism of the timepiece, it is important that the relative positions of the pivot axes of these pivoting elements are maintained with great precision.

Dans une pièce d'horlogerie connue (brevet suisse no 130727), tous les éléments pivotants pivotent dans la platine. Cette pièce d'horlogerie connue doit donc comporter une platine réalisée en un matériau résistant mécaniquement et pouvant être usiné avec une grande précision. Cela interdit l'emploi de matière plastique pour réaliser ladite platine.In a known timepiece (Swiss Patent No 130727), all the pivoting elements pivot in the plate. This known timepiece must therefore include a plate made of a mechanically resistant material and capable of being machined with great precision. This prohibits the use of plastic to make said plate.

Un objet de la présente invention est de réaliser une pièce d'horlogerie ayant une platine constituée, au moins en partie, en matière plastique, et dans laquelle les positions relatives des axes de pivotement des différents éléments pivotants soient assurées avec précision, cette pièce d'horlogerie devant aussi être de conception simple et de montage aisé.An object of the present invention is to produce a timepiece having a plate made up, at least in part, of plastic material, and in which the relative positions of the pivot axes of the various pivoting elements are ensured with precision, this piece d watchmaking should also be simple in design and easy to assemble.

Ce but est atteint, conformément à l'invention, du fait que la platine comporte des évidements, et que chaque élément pivotant pivote dans le pont de mécanisme et comporte un organe coaxial à son axe de pivotement, cet organe prenant place dans un évidement respectif de la platine et servant au pré-positionnement dudit élément pivotant.This object is achieved, in accordance with the invention, because the plate has recesses, and that each pivot element both pivots in the mechanism bridge and includes a member coaxial with its pivot axis, this member taking place in a respective recess in the plate and serving for the pre-positioning of said pivoting member.

Ainsi, les évidements de la platine et les organes précités des éléments pivotants constituent des moyens de pré-positionnement de ces éléments pivotants sur la platine. Ces moyens pré- positionnement facilitent notablement le montage de la piece d'horlogerie. Ce montage est, par exemple, effectué de la manière suivante : chacun des éléments pivotants est d'abord mis en place sur la platine où il est pré-positionneé du fait de l'engagement dudit organe dans un évidement correspondant de la platine. Ensuite, le pont de mécanisme est engagé sur l'ensemble des éléments pivotants ce qui fixe de facon précise les axes de pivotement de ces éléments pivotants dans leur position définitive.Thus, the recesses of the plate and the aforementioned members of the pivoting elements constitute means for pre-positioning these pivoting elements on the plate. These pre-positioning means notably facilitate the mounting of the timepiece. This assembly is, for example, carried out in the following manner: each of the pivoting elements is first put in place on the plate where it is pre-positioned due to the engagement of said member in a corresponding recess in the plate. Then, the mechanism bridge is engaged on all of the pivoting elements which precisely fixes the pivot axes of these pivoting elements in their final position.

Selon un mode de réalisation actuellement préféré, le pont de mécanisme est réalisé en une seule pièce avec le ressort-sautoir qui coopère avec la tirette pour déterminer les positions axiales stables de la tige du mécanisme de commande. Les évidements recevant lesdits organes des éléments pivotants du mécanisme de commande sont des trous réalisés dans la platine. De plus, ledit organe de pré-positionnement. que comporte chaque élément pivotant est constitué par une extrémité d'une pièce axiale chassée dans ledit élément pivotant; l'autre extrémité de cette pièce axiale forme un tourillon pivotant sans jeu latéral dans un trou du pont de mécanisme.According to a currently preferred embodiment, the mechanism bridge is made in one piece with the jumper spring which cooperates with the pull tab to determine the stable axial positions of the rod of the control mechanism. The recesses receiving said members of the pivoting elements of the control mechanism are holes made in the plate. In addition, said pre-positioning member. that each pivoting element comprises consists of one end of an axial piece driven into said pivoting element; the other end of this axial part forms a pivoting pin without lateral play in a hole in the mechanism bridge.

Les caractéristiques et avantage de l'invention seront mieux compris à la lecture de la description donnée ci-dessous d'un mode réalisation de l'invention, description faite en référence aux dessins annexés dans lesquels :

  • - La fig. 1 est une vue en plan d'une partie d'une montre électronique illustrant le mécanisme de commande de celle-ci, qui est du type à tirette, et qui permet notamment sa mise à l'heure et la correction d'un organe indicateur des quantièmes, et
  • - Les fig. 2 et 3 sont des coupes de détails, à échelle agrandie, suivant les lignes II-II et III-III de la fig. 1, respectivement.
The characteristics and advantage of the invention will be better understood on reading the description given below of an embodiment of the invention, description made with reference to the accompanying drawings in which:
  • - Fig. 1 is a plan view of a part of an electronic watch illustrating the control mechanism thereof, which is of the pull type, and which allows in particular its time setting and the correction of an indicator member dates, and
  • - Figs. 2 and 3 are detail sections, to scale enlarged, along lines II-II and III-III of fig. 1, respectively.

La montre représentée sur les dessins comporte un bati de mouvement contenant une platine 1. Une tige de commande 2, actionnable manuellement, est montée rotative et mobile axialement dans le bati. Cette tige de commande sert à la mise à l'heure de la montre, à la correction d'un indicateur des quantièmes (non représenté) ainsi qu'à d'autres fonctions qui ne seront pas indiquées ici en détail, de même que ne seront pas décrits en détail les mécanismes actionnés par le dispositif de commande, ces mécanismes étant étrangers à l'invention.The watch shown in the drawings comprises a movement frame containing a plate 1. A control rod 2, which can be actuated manually, is rotatably mounted and axially movable in the frame. This control rod is used for setting the time of the watch, for correcting a date indicator (not shown) as well as for other functions which will not be indicated here in detail, as well as The mechanisms actuated by the control device will not be described in detail, these mechanisms being foreign to the invention.

Le mécanisme de commande de la montre représentée comporte, outre la tige 2, un pignon coulant 19 porté par la tige 2 et un mécanisme de liaison associé ayant pour fonction à la fois d'assurer une transmission de mouvement axiale entre la tige 2 et le pignon 19, et de permettre à ces deux éléments 2 et 19 d'occuper trois positions axiales stables. Ce mécanisme de liaison comprend une tirette 3, articulée sur un tourillon 4, et qui porte une cheville 5 engagée dans une gorge 6 de la tige 2. La tirette 3 porte en outre une cheville 7 coopérant avec l'une ou l'autre de plusieurs encoches 8 que présente la tête 9a, d'un ressort formant sautoir 9.The control mechanism of the watch shown comprises, in addition to the rod 2, a sliding pinion 19 carried by the rod 2 and an associated connecting mechanism having the function both of ensuring an axial movement transmission between the rod 2 and the pinion 19, and allow these two elements 2 and 19 to occupy three stable axial positions. This connecting mechanism comprises a pull rod 3, articulated on a pin 4, and which carries a pin 5 engaged in a groove 6 of the rod 2. The pull rod 3 further carries a pin 7 cooperating with one or the other of several notches 8 presented by the head 9a, of a spring forming a jumper 9.

Le ressort 9 constitue une partie d'une pièce 90 comprenant une semelle 9b fixée à une armature métallique (ou grille) 10, surmoulée dans de la matière plastique 11 formant un substrat pour un module électronique (non représenté) de la montre (fig. 2). La grille 10 surmoulée dans la matière plastique 11 constitue la platine 1 du mouvement de la montre. La fixation de la semelle 9b du ressort 9 est assurée par des vis 12, prenant dans des piliers 13, chassés dans la grille 10. Une pièce métallique d'espacement 100 est interposée entre la platine 1 et la semelle 9b. La pièce d'espacement 100 est, comme la grille 10, surmoulée dans la matière plastique 11.The spring 9 constitutes a part of a part 90 comprising a sole 9b fixed to a metal frame (or grid) 10, overmolded in plastic material 11 forming a substrate for an electronic module (not shown) of the watch (fig. 2). The grid 10 molded in the plastic 11 constitutes the plate 1 of the watch movement. The fixing of the sole 9b of the spring 9 is ensured by screws 12, taking in pillars 13, driven into the grid 10. A metal spacer 100 is interposed between the plate 1 and the sole 9b. Like the grid 10, the spacer 100 is molded into the plastic 11.

Le mécanisme de commande comporte, en outre, une bascule 14, articulée sur un tourillon 15. De facon bien connue, une extrémité 14a de la bascule 14 s'engage dans une gorge annulaire du pignon coulant 19 porté par la tige 2, cette gorge étant délimitée par deux épaulements 2a et 2b que présente le pignon coulant 19. Une extrémité, opposée à la cheville 5, de la tirette 3 coopère avec un bord muni d'encoches 140 de la bascule 14. Cette dernière présente au-delà du tourillon 15, un levier correcteur des quantièmes 16, ce dernier étant articulé sur un tourillon 17 et portant un pignon 18 destiné à commander un mécanisme (non représenté) de correction de l'indicateur des quantièmes. Dans une certaine position axiale de la tige 2, le pignon coulant 19 est en prise avec le pignon 18, ce qui permet d'entraîner ce dernier en rotation.The control mechanism further comprises a rocker 14, articulated on a pin 15. As is well known, one end 14a of the rocker 14 engages in an annular groove in the sliding pinion 19 carried by the rod 2, this groove being delimited ted by two shoulders 2a and 2b that has the sliding pinion 19. One end, opposite the pin 5, of the pull tab 3 cooperates with an edge provided with notches 140 of the rocker 14. The latter has beyond the pin 15 , a date correcting lever 16, the latter being articulated on a pin 17 and carrying a pinion 18 intended to control a mechanism (not shown) for correcting the date indicator. In a certain axial position of the rod 2, the sliding pinion 19 is engaged with the pinion 18, which makes it possible to drive the latter in rotation.

L'ensemble des éléments pivotants du mécanisme de commande, à savoir la tirette 3, la bascule 14 et le levier correcteur des quantièmes 16, sont interposés entre la platine 1 et la pièce 90, que ce soit la partie 9b de celle-ci pour ce qui est de la bascule 14 et du levier 16, ou une partie de prolongement 9c de ladite pièce 90 pour ce qui est de la tirette 3, ce qui maintient en place ces différents éléments pivotants.All of the pivoting elements of the control mechanism, namely the pull tab 3, the rocker 14 and the date correcting lever 16, are interposed between the plate 1 and the part 90, whether this is part 9b of the latter for which is the rocker 14 and the lever 16, or an extension part 9c of said part 90 with regard to the pull tab 3, which keeps these different pivoting elements in place.

L'articulation des éléments pivotant 3, 14 et 16 du mécanisme de commande est assurée pour tous ceux-ci de façon identique, comme illustré par la fig. 3 pour ce qui est du levier correcteur 16. Ce dernier porte, chassé sur lui, le tourillon 17 s'engageant librement, mais sans jeu appréciable, dans un trou 101 correspondant de la semelle 9b du ressort de tirette 9, ce trou formant palier pour ledit tourillon 17.The articulation of the pivoting elements 3, 14 and 16 of the control mechanism is ensured for all of them in an identical manner, as illustrated in FIG. 3 with regard to the correcting lever 16. The latter carries, driven onto it, the pin 17 freely engaging, but without appreciable play, in a corresponding hole 101 in the sole 9b of the pull spring 9, this hole forming a bearing for said pin 17.

Chacun des tourillons 4,15 et 17 présente une tête coaxiale de forme cylindrique 4a, 15a et 17a respectivement, s'engageant avec jeu dans un trou 20 de forme cylindrique ménagé dans la platine 1 à partir de la face de cette dernière tournée vers les éléments pivotants 3,14 et 16. Les trous 20 ménagés dans la platine 1 servent, lors du montage de la montre, à pré-positionner les différents éléments pivotants 3, 14 et 16 du mécanisme de commande. La pièce 90 sert de palier de pivotement de ces éléments pivotants, une fois le montage de la montre terminé.Each of the pins 4,15 and 17 has a coaxial head of cylindrical shape 4a, 15a and 17a respectively, engaging with play in a hole 20 of cylindrical shape formed in the plate 1 from the face of this latter facing towards the pivoting elements 3,14 and 16. The holes 20 provided in the plate 1 are used, during assembly of the watch, to pre-position the various pivoting elements 3, 14 and 16 of the control mechanism. The part 90 serves as a pivot bearing for these pivoting elements, once the assembly of the watch has been completed.

Ainsi, la pièce formant ressort-sautoir de tirette 90 non seulement maintient en place les éléments pivotants 3, 14 et 16 du mécanisme de commande de la montre mais, qui plus est, assure leur pivotement.Thus, the part forming the pull-rod jumper spring 90 not only keeps the pivoting elements 3, 14 and 16 of the watch control mechanism in place but, moreover, ensures their pivoting.

Lors du montage de la montre, on place d'abord les têtes 4a, 15a, 17a des tourillons 4, 15, 17, sur lesquelles auront été préalablement chassés, respectivement la tirette 3, la bascule 14 et le levier 16, dans les trous 20 correspondants dans la platine 1 pour que la tirette, la bascule et le levier correcteur soient approximativement en place sur la platine.When mounting the watch, the heads 4a, 15a, 17a of the pins 4, 15, 17 are first placed, on which the pull tab 3, the lever 14 and the lever 16, respectively, have been driven into the holes 20 correspondents in plate 1 so that the pull tab, the rocker and the correcting lever are approximately in place on the plate.

La pièce formant ressort de tirette 90 est alors mise en place, les tourillons 4, 15 et 17 s'engageant dans les trous 20 correspondants de ladite pièce 90. Cet engagement est facilité par le fait que les extrémités des tourillons sont chanfreinés, comme indiqué en 21 à la fig. 3, pour ce qui est du cas du tourillon 17. Les éléments pivotants du mécanisme de commande sont ainsi amenés dans leur position exacte dans laquelle ils seront maintenus par le serrage des vis 12.The pull rod spring part 90 is then put in place, the pins 4, 15 and 17 engaging in the corresponding holes 20 of said part 90. This engagement is facilitated by the fact that the ends of the pins are chamfered, as indicated at 21 in fig. 3, in the case of the pin 17. The pivoting elements of the control mechanism are thus brought into their exact position in which they will be held by tightening the screws 12.

Bien entendu, au lieu des trous 20 coopérant avec les têtes de tourillon 4a, 15a, 17a, on pourrait réaliser sur la platine 1 d'autres évidements de pré-positionnement capables chacun de coopérer avec un organe de forme convenable prévu sur un élément pivotant, afin de positionner avec jeu les axes des éléments pivotants, au moment où ces derniers sont mis en place sur la platine avant que ne soit montée la pièce 90 formant ressort-sautoir de tirette.Of course, instead of the holes 20 cooperating with the trunnion heads 4a, 15a, 17a, one could make on the plate 1 other pre-positioning recesses each capable of cooperating with a member of suitable shape provided on a pivoting element , in order to position with play the axes of the pivoting elements, at the moment when the latter are put in place on the plate before the part 90 forming the spring-jumper of the pull tab is mounted.

Par ailleurs, la platine 1 constituée partiellement en matière plastique peut être autre qu'une grille métallique surmoulée dans de la matière plastique.Furthermore, the plate 1 partially made of plastic material may be other than a metal grid molded in plastic material.
