Abstract

The time piece has a balance bridge (4) with a base (18) associated to a balance bridge deformation unit formed of an adjusting screw (34). The screw is adjusted to vary the distance between the base and a main plate (14) by the deformation of a plate (10) at level of zones (22, 24) of less mechanical resistance, which are provided on either side of a central part (20) of the plate (10) to localize deformations generated by the screw. The central part where the bearing is arranged moves relative to the main plate to adjust the shake in the balance when the plate (10) is deformed.

Description

La prรฉsente invention concerne une piรจce d'horlogerie mรฉcanique comprenant des moyens de rรฉglage de l'รฉbat d'un mobile tournant, en particulier de l'รฉbat d'un balancier.The present invention relates to a mechanical timepiece comprising means for adjusting the play of a rotating wheel, in particular the play of a balance wheel.

Il est connu du brevet suisse No. 20552 au nom de J. L. Kurtz, dรฉposรฉ le 1er novembre 1899 , un pont de balancier associรฉ ร  des moyens de rรฉglage de la position relative des deux paliers dans lesquels pivotent respectivement les deux extrรฉmitรฉs de l'axe du balancier. Le pont de balancier dรฉcrit est du type simple, c'est-ร -dire avec une seule base fixรฉe ร  une platine et une planche reliรฉe ร  une extrรฉmitรฉ ร  cette seule base et prรฉsentant ร  son autre extrรฉmitรฉ libre une ouverture pour l'agencement d'un palier. Le pont de balancier est fixรฉ ร  la platine par une seule vis de serrage traversant la seule base.It is known from the patent No 20552 on behalf of JL Kurtz, filed on 1 November 1899 , a balance bridge associated with means for adjusting the relative position of the two bearings in which the two ends of the balance shaft respectively pivot. The pendulum bridge described is of the simple type, that is to say with a single base fixed to a plate and a board connected at one end to this single base and having at its other free end an opening for the arrangement of 'a step. The balance bridge is fixed to the plate by a single clamping screw passing through the sole base.

Dans ce document, le rรฉglage de l'รฉbat de l'axe de balancier est effectuรฉ par un ajustement de la hauteur de la planche du pont de balancier. Pour ce faire, il est prรฉvu trois vis de rรฉglage en pรฉriphรฉrie de la vis de serrage. Les trois vis de rรฉglage traversent la base du pont et s'appuient du cรดtรฉ de la platine contre trois autres vis complรฉmentaires dรฉfinissant ainsi trois points d'appui pour les trois vis de rรฉglage. En vissant ou dรฉvissant les trois vis de rรฉglage de maniรจre sensiblement homogรจne, il est ainsi possible de varier la hauteur de la planche du pont de balancier, c'est-ร -dire de varier la distance relative de cette planche ร  la platine. Dans ce document il est prรฉvu que la planche reste horizontale, c'est-ร -dire parallรจle au plan gรฉnรฉral de la platine. Ainsi, l'horloger qui rรจgle l'รฉbat du balancier doit agir sur les trois vis de rรฉglage en les tournant successivement et de maniรจre rรฉpรฉtรฉe jusqu'ร  ce que la planche atteigne une hauteur dรฉfinissant un รฉbat correct pour le balancier. Ceci prรฉsente un dรฉsavantage important pour le montage de la piรจce d'horlogerie et le rรฉglage de l'รฉbat du balancier. De plus, trois vis de rรฉglage augmentent le coรปt de cette piรจce d'horlogerie et leur agencement en pรฉriphรฉrie de la vis de serrage nรฉcessite des dimensions relativement grandes pour la base du pont. Ceci pose un problรจme pour la conception du mouvement horloger et en particulier pour l'agencement du pont de balancier.In this document, the adjustment of the balance axis of the frog is made by adjusting the height of the board of the pendulum bridge. To do this, three adjusting screws are provided at the periphery of the clamping screw. The three adjustment screws pass through the base of the bridge and rest against the side of the plate against three other complementary screws thus defining three points of support for the three adjustment screws. By screwing or unscrewing the three adjustment screws in a substantially homogeneous manner, it is thus possible to vary the height of the board of the balance bridge, that is to say to vary the relative distance of this board to the board. In this document it is expected that the board remains horizontal, that is to say parallel to the general plane of the plate. Thus, the watchmaker who adjusts the balance of the balance must act on the three adjustment screws by turning them successively and repeatedly until the board reaches a height defining a correct frog for the pendulum. This presents an important disadvantage for the assembly of the timepiece and the adjustment of the balance of the balance. In addition, three adjustment screws increase the cost of this timepiece and their arrangement at the periphery of the clamping screw requires relatively large dimensions for the base of the bridge. This poses a problem for the design of the watch movement and in particular for the arrangement of the balance bridge.

On connaรฎt aussi une piรจce d'horlogerie vendue par la maison Rolex qui possรจde un systรจme de rรฉglage de l'รฉbat du balancier. Dans cette piรจce d'horlogerie, le pont de balancier est du type double, c'est-ร -dire prรฉsentant deux bases agencรฉes aux deux extrรฉmitรฉs de la planche du pont et permettant de fixer ce pont de balancier de maniรจre rigide de part et d'autre du palier agencรฉ sensiblement au centre de la planche. Les deux bases sont respectivement fixรฉes ร  la platine par deux vis de serrage. Chacune des deux vis de serrage est vissรฉe ร  l'intรฉrieur d'un cylindre chassรฉ dans la platine. Ce cylindre prรฉsente ร  l'intรฉrieur un taraudage pour la vis de serrage et un filetage extรฉrieur pour un รฉcrou de rรฉglage. Les deux bases du pont de balancier sont maintenues en appui contre les deux รฉcrous par les deux vis de serrage. Un ressort de friction formรฉ par une rondelle รฉlastiquement dรฉformable est prรฉvue sous l'รฉcrou de maniรจre ร  maintenir la position de celui-ci lorsqu'il n'est pas actionnรฉ par un horloger. Les deux vis de serrage sont prรฉvues respectivement ร  la pรฉriphรฉrie des deux bases respectives de maniรจre ร  permettre de tourner les รฉcrous de rรฉglage qui prรฉsentent des cannelures sur la surface latรฉrale externe pour faciliter leur actionnement ร  l'aide d'un outil appropriรฉ et ainsi le rรฉglage de l'รฉbat du balancier.There is also a timepiece sold by Rolex which has a system for adjusting the balance of the balance. In this timepiece, the balance bridge is of the double type, that is to say having two bases arranged at both ends of the bridge board and for fixing the balance bridge rigidly on both sides. other of the landing arranged substantially in the center of the board. The two bases are respectively fixed to the plate by two clamping screws. Each of the two clamping screws is screwed inside a cylinder driven into the plate. This cylinder has inside a tapping for the clamping screw and an external thread for an adjusting nut. The two bases of the balance bridge are held in abutment against the two nuts by the two clamping screws. A friction spring formed by an elastically deformable washer is provided under the nut so as to maintain the position thereof when not actuated by a watchmaker. The two clamping screws are respectively provided at the periphery of the two respective bases so as to allow the adjusting nuts which have splines to rotate on the outer lateral surface to facilitate their actuation with the aid of a suitable tool and thus the adjusting the balance of the balance.

Le systรจme de rรฉglage de l'รฉbat d'un balancier dรฉcrit ci-avant prรฉsente certains inconvรฉnients. Premiรจrement il est relativement complexe et onรฉreux. En effet, ce systรจme comprend deux piรจces cylindriques, avec un taraudage ร  l'intรฉrieur et un filetage extรฉrieur, qui doivent รชtre chassรฉes dans la platine. De plus, ce systรจme comprend deux รฉcrous de rรฉglage cannelรฉs. Ensuite, pour permettre le rรฉglage de la hauteur de la planche du pont avec le balancier en place, il est nรฉcessaire de prรฉvoir les vis de serrage en bordure extรฉrieure des deux bases et de prรฉvoir un espace libre en pรฉriphรฉrie des deux vis de serrage pour permettre un accรจs aux รฉcrous de rรฉglage qui sortent latรฉralement dessous les bases. Finalement, comme il est รฉgalement prรฉvu de maintenir la planche du pont du balancier horizontal, l'horloger doit actionner successivement les deux รฉcrous de rรฉglage pour varier la hauteur de cette planche jusqu'ร  ce qu'il obtienne l'รฉbat souhaitรฉ pour le balancier. Ensuite, il doit encore visser les deux vis de serrage de maniรจre ร  fixer rigidement le pont de balancier ร  la platine. Ce systรจme de rรฉglage est donc relativement compliquรฉ et nรฉcessite en particulier d'agir sur deux รฉcrous de rรฉglage disposรฉs de part et d'autre du balancier.The balance control system of a balance described above has certain disadvantages. Firstly it is relatively complex and expensive. Indeed, this system comprises two cylindrical parts, with an internal thread and an external thread, which must be driven into the plate. In addition, this system includes two fluted adjusting nuts. Then, to allow adjustment of the height of the bridge board with the balance in place, it is necessary to provide the clamping screws on the outer edge of the two bases and to provide a free space at the periphery of the two clamping screws to allow an access to the adjusting nuts coming out laterally below the bases. Finally, as it is also planned to maintain the board of the horizontal beam bridge, the watchmaker must successively actuate the two adjusting nuts to vary the height of this board until it gets the desired frolicking for the balance . Then he must still screw the two clamping screws so as to rigidly fix the balance bridge to the plate. This adjustment system is relatively complicated and requires in particular to act on two adjusting nuts arranged on either side of the balance.

Un but de la prรฉsente invention est de proposer un dispositif de rรฉglage de l'รฉbat d'un mobile tournant dans une piรจce d'horlogerie, en particulier d'un balancier, qui soit relativement peu onรฉreux et permettant de rรฉgler l'รฉbat du mobile tournant de maniรจre efficace et rapide.An object of the present invention is to provide a device for adjusting the play of a mobile rotating in a timepiece, in particular a balance, which is relatively inexpensive and to adjust the frolicking of the mobile rotating efficiently and quickly.

A cet effet la prรฉsente invention concerne une piรจce d'horlogerie mรฉcanique รฉquipรฉe d'un mobile tournant qui comprend un axe ou arbre dont une extrรฉmitรฉ pivote dans un premier palier portรฉ par un pont et l'autre extrรฉmitรฉ pivote dans un second palier agencรฉ dans une platine, cette piรจce d'horlogerie comprenant des moyens de rรฉglage de l'รฉbat de cet axe ou arbre du mobile tournant Ces moyens de rรฉglage sont formรฉs d'une part par un moyen de fixation classique d'une premiรจre partie du pont ร  la platine qui laisse cette premiรจre partie dans une position fixe relativement ร  la platine et, d'autre part, par un moyen de dรฉformation du pont qui est agencรฉ pour varier la position relative entre une deuxiรจme partie de ce pont et la platine en dรฉformant ce pont, ces premiรจre et deuxiรจme parties รฉtant prรฉvues pour qu'un actionnement du moyen de dรฉformation engendre une variation de la position du premier palier relativement au deuxiรจme palier.For this purpose the present invention relates to a mechanical timepiece equipped with a rotating wheel which comprises an axis or shaft whose one end pivots in a first bearing carried by a bridge and the other end pivots in a second bearing arranged in a platinum, this timepiece comprising means for adjusting the freshness of this axis or shaft of the mobile rotating These adjustment means are formed firstly by a conventional fixing means of a first part of the bridge to the plate which leaves this first part in a fixed position relative to the plate and, secondly, by means of deformation of the bridge which is arranged to vary the relative position between a second part of this bridge and the plate by deforming this bridge, these first and second parts being provided for an actuation of the deformation means causes a variation of the position of the first bearing relative to the second bearing.

Selon un mode de rรฉalisation prรฉfรฉrรฉ, la piรจce d'horlogerie comprend entre lesdites premiรจre et deuxiรจme parties dudit pont au moins une zone de moindre rรฉsistance mรฉcanique dรฉfinissant une zone de dรฉformation localisรฉe ou une articulation flexible entre ces premiรจre et deuxiรจme parties. Dans une variante proposรฉe, cette zone de dรฉformation localisรฉe est dรฉfinie par une rainure transversale effectuรฉe du cรดtรฉ de la face infรฉrieure de la planche du pont.According to a preferred embodiment, the timepiece comprises between said first and second parts of said bridge at least one zone of lower mechanical resistance defining a localized deformation zone or a flexible articulation between these first and second parts. In a proposed variant, this localized deformation zone is defined by a transverse groove made on the side of the underside of the deck board.

Dans une variante prรฉfรฉrรฉe, le pont est double et les premiรจre et deuxiรจme parties dont dรฉfinies par les deux bases du pont. Dans ce dernier cas, il est prรฉvu deux zones de moindre rรฉsistance mรฉcanique dรฉfinies par deux rainures transversales agencรฉes respectivement aux deux extrรฉmitรฉs de la planche, c'est-ร -dire ร  la pรฉriphรฉrie immรฉdiate des deux bases.In a preferred embodiment, the bridge is double and the first and second parts of which defined by the two bases of the bridge. In the latter case, there are two zones of lesser mechanical strength defined by two transverse grooves respectively arranged at both ends of the board, that is to say at the immediate periphery of the two bases.

Finalement, les moyens de rรฉglage de l'รฉbat du mobile tournant sont remarquables par le fait que la variation de la distance entre les deux paliers dans lesquels pivote ce mobile tournant est obtenue par dรฉformation dudit pont qui peut รชtre obtenue par la variation de la position d'un seul รฉlรฉment, notamment d'une seule vis de rรฉglage permettant de dรฉplacer ladite deuxiรจme partie du pont et de dรฉformer ainsi ce pont. Il en rรฉsulte une lรฉgรจre inclinaison de la planche du pont sans effet nรฉgatif sur le pivotement du mobile tournant รฉtant donnรฉ que les tolรฉrances de fabrication nรฉcessitent seulement un ajustement fin de la position de la planche relativement ร  la platine pour obtenir un รฉbat optimal du mobile tournant.Finally, the means for adjusting the fret of the rotating wheel are remarkable in that the variation of the distance between the two bearings in which this rotating wheel pivots is obtained by deformation of said bridge which can be obtained by the variation of the position a single element, including a single adjusting screw for moving said second part of the bridge and thus deform this bridge. This results in a slight inclination of the deck board with no negative effect on the pivoting of the rotating wheel as manufacturing tolerances require only a fine adjustment of the position of the board relative to the plate to obtain an optimal frust of the rotating mobile .

A la figure 1 est reprรฉsentรฉ un premier mode de rรฉalisation d'une piรจce d'horlogerie mรฉcanique 2 รฉquipรฉe d'un mobile tournant et comprenant des moyens de rรฉglage de l'รฉbat de ce mobile tournant selon la prรฉsente invention.In Figure 1 is shown a first embodiment of a mechanical timepiece 2 equipped with a rotating wheel and comprising means for adjusting the play of this rotating wheel according to the present invention.

Le premier mode de rรฉalisation de l'invention sera dรฉcrit ci-aprรจs ร  l'aide des figures 1 ร  7. Le pont dans ce mode de rรฉalisation est un pont de balancier 4 et le mobile tournant est un balancier 6. De maniรจre classique, le balancier 6 comprend un axe dont une premiรจre extrรฉmitรฉ pivote dans un premier palier portรฉ par la planche 10 du pont de balancier. Le premier palier est agencรฉ dans une ouverture d'un porte-piton 8 avec un dispositif pare-choc connu de l'homme du mรฉtier. Le porte-piton 8 repose sur l'assise centrale 12 du pont 4. La deuxiรจme extrรฉmitรฉ de l'axe du balancier pivote dans un second palier agencรฉ dans une platine 14 de la piรจce d'horlogerie 2.The first embodiment of the invention will be described hereinafter with reference to FIGS. 1 to 7. The bridge in this embodiment is a balance bridge 4 and the rotating mobile is a rocker 6. In a conventional manner, the balance 6 comprises an axis of which a first end pivots in a first bearing carried by the board 10 of the balance bridge. The first bearing is arranged in an opening of a bolt carrier 8 with a bumper device known to those skilled in the art. The bolt carrier 8 rests on the central seat 12 of the bridge 4. The second end of the axis of the balance pivots in a second bearing arranged in a plate 14 of the timepiece 2.

Le pont de balancier 4 est un pont double formรฉ de deux bases 16 et 18 agencรฉes respectivement d'un cรดtรฉ et de l'autre de la planche 10 et donc du premier palier agencรฉ dans la partie centrale 20 de ce pont. L'assise 12 pour le porte-piton prรฉsente une รฉpaisseur infรฉrieure ร  celle de la planche 10 dans ses deux parties directement adjacentes ร  cette assise. Selon une caractรฉristique particuliรจre de l'invention, le pont 4 comprend deux zones de moindre rรฉsistance mรฉcanique 22 et 24 agencรฉes respectivement aux deux rรฉgions d'extrรฉmitรฉ de la planche 10, c'est-ร -dire respectivement entre les deux bases 16 et 18 et la partie centrale 20 portant le premier palier pour l'axe du balancier. Ces deux zones de moindre rรฉsistance mรฉcanique sont formรฉes chacune par une zone transversale dรฉfinie par une rainure d'une certaine largeur. Nous reviendrons sur la fonction de ces zones de moindre rรฉsistance mรฉcanique par la suite.The balance bridge 4 is a double bridge formed of two bases 16 and 18 respectively arranged on one side and the other of the board 10 and therefore the first bearing arranged in the central portion 20 of this bridge. The seat 12 for the peg carrier has a thickness less than that of the board 10 in its two parts directly adjacent to this seat. According to a particular characteristic of the invention, the bridge 4 comprises two areas of least mechanical resistance 22 and 24 respectively arranged at the two end regions of the board 10, that is to say between the two bases 16 and 18 respectively. and the central portion 20 carrying the first bearing for the axis of the balance. These two areas of least mechanical strength are each formed by a transverse area defined by a groove of a certain width. We will return to the function of these areas of least mechanical resistance thereafter.

Selon l'invention, il est prรฉvu des moyens de rรฉglage de l'รฉbat du balancier qui sont formรฉs d'une part par un moyen de fixation classique d'une premiรจre partie 16 du pont 4, cette premiรจre partie รฉtant dรฉfinie dans ce mode de rรฉalisation par la base 16. Le moyen de fixation classique est constituรฉ par une vis 30 qui fixe la base 16 ร  la platine 14 de maniรจre rigide en laissant cette base dans une position fixe relativement ร  cette platine, en appui contre cette derniรจre. D'autre part, la deuxiรจme base 18 du pont 4 dรฉfinit une deuxiรจme partie fixรฉe ร  ladite platine au moyen d'une vis de serrage 32. Cette deuxiรจme partie 18 est associรฉe ร  un moyen 34 de dรฉformation du pont 4. Ce moyen de dรฉformation est constituรฉ ici par une vis 34 de diamรจtre relativement grand et percรฉe en son centre. Cette vis de rรฉglage 34 comprend une tรชte plate 36 munie d'une fente permettant de visser cette vis depuis la partie infรฉrieure du pont 4. La vis de rรฉglage 34 comprend en outre un cylindre 38 prรฉsentant un filetage extรฉrieur fin de maniรจre ร  pouvoir varier finement la distance entre la surface externe 37 de la tรชte 36 et la surface infรฉrieure 5 du pont 4. Le trou 40 qui traverse la vis 34 prรฉsente un diamรจtre supรฉrieure ร  celui de la vis de serrage 32, de maniรจre que celle-ci peut รชtre introduite librement dans ce trou traversant 40.According to the invention, there is provided means for adjusting the balance of the balance which are formed on the one hand by a conventional fixing means of a first part 16 of the bridge 4, this first part being defined in this mode of The conventional fastening means is constituted by a screw 30 which fixes the base 16 to the plate 14 rigidly leaving the base in a fixed position relative to this plate, bearing against it. On the other hand, the second base 18 of the bridge 4 defines a second portion fixed to said plate by means of a clamping screw 32. This second portion 18 is associated with a deformation means 34 of the bridge 4. This deformation means is constituted here by a screw 34 of relatively large diameter and pierced at its center. This adjusting screw 34 comprises a flat head 36 provided with a slot for screwing this screw from the lower part of the bridge 4. The adjusting screw 34 further comprises a cylinder 38 having a fine external thread so as to be able to vary finely the distance between the outer surface 37 of the head 36 and the lower surface 5 of the bridge 4. The hole 40 which passes through the screw 34 has a diameter greater than that of the clamping screw 32, so that it can be introduced freely in this through hole 40.

La vis 34 est vissรฉe dans un trou 42 traversant la base 18 du pont 4 Le trou 42 prรฉsente un รฉlargissement dans la partie supรฉrieure de la base 18 avec une surface annulaire sensiblement plane et servant de butรฉe ร  la tรชte de la vis de serrage 32. Cette vis 32 est vissรฉe ร  son extrรฉmitรฉ infรฉrieure dans la platine 14 pour assurer la fixation de la base 18 ร  la platine 14.The screw 34 is screwed into a hole 42 passing through the base 18 of the bridge 4 The hole 42 has an enlargement in the upper part of the base 18 with a substantially flat annular surface and serves as a stop at the head of the clamping screw 32. This screw 32 is screwed at its lower end into the plate 14 to secure the base 18 to the plate 14.

La vis rรฉglage 34 prรฉsente ร  son extrรฉmitรฉ supรฉrieure opposรฉe ร  la tรชte 36 une partie annulaire supรฉrieure prรฉsentant deux fentes 44 diamรฉtralement opposรฉes et agencรฉes pour permettre d'y insรฉrer un tournevis pour tourner cette vis de rรฉglage 34 depuis la face supรฉrieure 46 du pont en l'absence de la vis de serrage 32, comme cela ressort en particulier des figures 4 et 6. Un ressort de friction ayant la forme d'une rondelle incurvรฉe 48 est agencรฉ entre la tรชte 36 de la vis 34 et la surface infรฉrieure 5 de la base 18. Pour assurer un positionnement de cette base 18 dans le plan gรฉnรฉral du mouvement horloger 2, une goupille de positionnement 50 est prรฉvue.The adjusting screw 34 has at its upper end opposite to the head 36 an upper annular portion having two diametrically opposed slots 44 and arranged to allow a screwdriver to be inserted to turn this adjusting screw 34 from the upper face 46 of the bridge in the opposite direction. the absence of the clamping screw 32, as is particularly apparent from FIGS. 4 and 6. A friction spring having the shape of a curved washer 48 is arranged between the head 36 of the screw 34 and the lower surface 5 of the base 18. To ensure positioning of this base 18 in the general plane of the watch movement 2, a positioning pin 50 is provided.

En tournant la vis de rรฉglage 34, on varie la position relative entre la base 18 et la platine 14 รฉtant donnรฉ que la surface infรฉrieure 37 de la tรชte 36 repose sur cette platine. Pour effectuer le rรฉglage de la hauteur de la base 18, on enlรจvera la vis de serrage 32 de maniรจre ร  pouvoir effectuer ce rรฉglage depuis la surface supรฉrieure 46 du pont 4 par l'ouverture traversante 42. Pour ce faire, l'horloger maintiendra par exemple ร  l'aide d'un outil appropriรฉ la vis 34 en appui contre la platine 14 si cela s'avรจre nรฉcessaire Etant donnรฉ que la base 16 est fixรฉe ร  la platine dans une position invariable, un actionnement de la vis de rรฉglage 34 engendre une dรฉformation du pont 4, comme cela est reprรฉsentรฉ ร  la figure 7. Ainsi, en actionnant la vis de rรฉglage 34, on varie la distance entre la base 18 et la platine 14 et on dรฉforme la planche 10 de sorte que la zone centrale 20, oรน est situรฉ le palier supรฉrieur pour l'axe du balancier, subit รฉgalement un dรฉplacement permettant ainsi le rรฉglage de l'รฉbat de ce balancier.By turning the adjustment screw 34, the relative position between the base 18 and the plate 14 is varied since the lower surface 37 of the head 36 rests on this plate. To adjust the height of the base 18, the clamping screw 32 will be removed so as to be able to make this adjustment from the upper surface 46 of the bridge 4 through the through opening 42. To do this, the watchmaker will maintain by example using a suitable tool the screw 34 bearing against the plate 14 if necessary Since the base 16 is fixed to the plate in an invariable position, an actuation of the adjusting screw 34 generates a deformation of the bridge 4, as shown in Figure 7. Thus, by actuating the adjusting screw 34, the distance between the base 18 and the plate 14 is varied and the plate 10 is deformed so that the central zone 20 , where is located the upper bearing for the axis of the balance, also undergoes a displacement thus allowing the adjustment of the balance of this balance.

Comme dรฉjร  dรฉcrit prรฉcรฉdemment, la planche 10 comprend ร  ses deux parties d'extrรฉmitรฉ deux zones 22 et 24 de moindre rรฉsistance mรฉcanique qui dรฉfinissent chacune une zone de dรฉformation localisรฉe ou articulation flexible entre les deux bases 16 et 18. Ces zones de dรฉformation localisรฉe sont obtenues par l'usinage de deux rainures du cรดtรฉ infรฉrieur de la planche 10 qui dรฉfinissent des zones transversales du pont 4 ayant une moindre รฉpaisseur que les deux rรฉgions adjacentes 54 et 56, respectivement 55 et 57. La dรฉformation du pont est ainsi localisรฉe essentiellement dans les deux zones transversales 22 et 24 de sorte que les bases 16 et 18 subissent quasi aucune dรฉformation et la partie centrale 20 de la planche 10 demeure sensiblement plane. De plus, ces zones 22 et 24 permettent de diminuer globalement les tensions engendrรฉes dans le pont de balancier 4 lorsque la base 18 est dรฉplacรฉe en hauteur relativement ร  la base 16. Ainsi, l'ajustement de l'รฉbat du balancier peut engendrer une certaine inclinaison de la partie centrale 20 de la planche 10, mais cette inclinaison demeure faible.As already described above, the board 10 comprises at its two end portions two zones 22 and 24 of least mechanical strength which define each a zone of localized deformation or flexible articulation between the two bases 16 and 18. These zones of localized deformation are obtained by the machining of two grooves on the lower side of the plate 10 which define transverse zones of the bridge 4 having a smaller thickness that the two adjacent regions 54 and 56, respectively 55 and 57. The deformation of the bridge is thus located essentially in the two transverse zones 22 and 24 so that the bases 16 and 18 undergo almost no deformation and the central portion 20 of the board 10 remains substantially flat. In addition, these zones 22 and 24 make it possible to reduce overall the tensions generated in the balance bridge 4 when the base 18 is displaced in height relative to the base 16. Thus, the adjustment of the balance of the balance can generate some inclination of the central portion 20 of the board 10, but this inclination remains low.

Grรขce ร  la variante prรฉfรฉrรฉe de l'invention dรฉcrite ici, l'assise 12 du porte-piton demeure plate et soumise ร  relativement peu de tension. On remarquera que l'agencement des zones de moindre รฉpaisseur 22 et 24 sont d'autant plus nรฉcessaire que l'assise 12 du porte-piton est formรฉe par un usinage de la planche 10. Ainsi, l'assise 12 prรฉsente une รฉpaisseur moindre que les rรฉgions pรฉriphรฉriques 54 et 55 ร  cette assise 12, ce qui rend la zone centrale 20 plus facilement dรฉformable. De ce fait, dans la variante reprรฉsentรฉe ร  la figure 8, en absence des zones transversales 22 et 24, le pont 4A prรฉsente sensiblement une dรฉformation en S, la dรฉformation de la planche 10A รฉtant situรฉe substantiellement au niveau de sa partie centrale 20A. Cette variante de rรฉalisation est donc moins avantageuse de sorte que la variante dรฉcrite prรฉcรฉdemment ร  la figure 7 est prรฉfรฉrรฉe. L'homme du mรฉtier pourra concevoir d'autres ponts et d'autres moyens pour rรฉduire les tensions internes dans la planche du pont dรฉformรฉe par les moyens de rรฉglage de l'รฉbat du balancier selon la prรฉsente invention.With the preferred embodiment of the invention described here, the seat 12 of the bolt carrier remains flat and subjected to relatively little tension. It will be noted that the arrangement of the thinner zones 22 and 24 is all the more necessary as the seat 12 of the peg carrier is formed by a machining of the board 10. Thus, the seat 12 has a thickness less than the peripheral regions 54 and 55 at this seat 12, which makes the central zone 20 more easily deformable. Therefore, in the variant shown in Figure 8, in the absence of the transverse zones 22 and 24, the bridge 4A substantially has an S-shaped deformation, the deformation of the board 10A is located substantially at its central portion 20A. This variant embodiment is therefore less advantageous so that the variant described previously in FIG. 7 is preferred. Those skilled in the art can design other bridges and other means to reduce the internal stresses in the board of the deformed bridge by the balance of the equilibrium adjusting means according to the present invention.

La prรฉsente invention est aussi remarquable par le fait que le rรฉglage de l'รฉbat du balancier ou d'un mobile tournant est rรฉalisรฉ par un moyen de dรฉformation du pont concernรฉ, ce moyen de dรฉformation รฉtant agencรฉ de maniรจre ร  รชtre actionnรฉ par la variation de la position d'un seul รฉlรฉment de rรฉglage 34. Ensuite, cette variation peut รชtre effectuรฉe depuis la face supรฉrieure du pont associรฉ au mobile tournant dont l'รฉbat est rรฉglรฉ. Le dispositif de rรฉglage de l'รฉbat selon la prรฉsente invention est relativement simple et donc peu onรฉreux. De plus, l'agencement coaxial de la vis de serrage 32 et de la vis de rรฉglage 34 n'augmente pas l'encombrement du pont.The present invention is also remarkable in that the adjustment of the play of the rocker arm or of a rotating wheel is effected by means of deformation of the bridge concerned, this deformation means being arranged so as to be actuated by the variation of the position of a single adjustment element 34. Then, this variation can be performed from the upper face of the bridge associated with the rotating mobile whose frost is set. The frost control device according to the present invention is relatively simple and therefore inexpensive. In addition, the coaxial arrangement of the clamping screw 32 and the adjusting screw 34 does not increase the overall size of the bridge.

Le montage du dispositif de rรฉglage de l'รฉbat est effectuรฉ aisรฉment en vissant simplement la vis de rรฉglage 34 depuis la face infรฉrieure 5 du pont 4 jusqu'ร  ce que sa tรชte soit environ ร  une certaine hauteur dรฉfinie. Ensuite, le pont peut รชtre assemblรฉ ร  la platine avec le balancier montรฉ dans les deux paliers qui lui sont associรฉs. Ensuite, l'รฉbat du balancier (ou d'un autre mobile tournant) peut รชtre rรฉglรฉ simplement en tournant la vis 34 ร  l'aide de la fente 44 prรฉvue ร  son extrรฉmitรฉ supรฉrieure opposรฉe ร  la tรชte 36, cette extrรฉmitรฉ supรฉrieure รฉtant accessible par un outil depuis la face supรฉrieure 46 du pont au travers de l'ouverture 42 traversant la base 18. Une fois le rรฉglage effectuรฉ, la vis 32 est insรฉrรฉe dans le trou traversant 40 de la vis de rรฉglage 34 et serrรฉe de maniรจre ร  fixer rigidement la base 18 ร  la platine 14. La rondelle รฉlastique 48 assure un maintien de la vis de rรฉglage 34 dans la position prรฉvue. Une fois l'ajustement de la distance entre les deux paliers finement effectuรฉ au moyen de la vis de rรฉglage 34, le systรจme de rรฉglage de la hauteur du pont 4 est masquรฉ et le pont est solidement fixรฉ ร  la platine.The mounting of the lightening adjustment device is easily performed by simply screwing the adjusting screw 34 from the lower face 5 of the bridge 4 until its head is about a certain height. Then the bridge can be assembled to the plate with the rocker mounted in the two bearings associated with it. Then, the equilibrium of the balance (or of another mobile rotating) can be adjusted simply by turning the screw 34 with the slot 44 provided at its upper end opposite the head 36, this upper end being accessible by a tool from the upper face 46 of the bridge through the opening 42 through the base 18. Once the adjustment is made, the screw 32 is inserted into the through hole 40 of the adjusting screw 34 and tightened so as to rigidly fix the base 18 to the plate 14. The spring washer 48 maintains a set screw 34 in the intended position. Once the adjustment of the distance between the two bearings is finely carried out by means of the adjustment screw 34, the height adjustment system of the bridge 4 is masked and the bridge is firmly fixed to the plate.

On remarquera que la prรฉsente invention peut รฉgalement s'appliquer ร  un mouvement horloger รฉquipรฉ d'un tourbillon et dans lequel l'รฉbat de la cage du tourbillon est ajustรฉ ร  l'aide du dispositif de la prรฉsente invention associรฉ au pont du tourbillon portant un des deux paliers dans lequel pivote la cage du tourbillon.It should be noted that the present invention can also be applied to a watch movement equipped with a vortex and in which the vortex of the tourbillon cage is adjusted by means of the device of the present invention associated with the tourbillon bridge carrying a two bearings in which rotates the vortex cage.

A la figure 9 est reprรฉsentรฉ schรฉmatiquement en coupe un deuxiรจme mode de rรฉalisation d'une piรจce d'horlogerie selon la prรฉsente invention.In Figure 9 is shown schematically in section a second embodiment of a timepiece according to the present invention.

Dans ce mode de rรฉalisation, le pont de balancier 64 est du type simple, c'est-ร -dire avec une base 68 agencรฉe ร  une extrรฉmitรฉ de la planche 70 qui prรฉsente ร  son autre extrรฉmitรฉ libre 72 un premier palier 74 dans lequel pivote l'axe 76 du balancier 6. La seconde extrรฉmitรฉ de l'axe 76 pivote dans un palier 78 agencรฉ dans la platine 14. Les paliers 74 et 78 sont reprรฉsentรฉs de maniรจre schรฉmatique ร  la figure 9. De maniรจre classique, le palier 74 est gรฉnรฉralement associรฉ ร  un dispositif pare-choc connu de l'homme du mรฉtier.In this embodiment, the balance bridge 64 is of the simple type, that is to say with a base 68 arranged at one end of the board 70 which has at its other free end 72 a first bearing 74 in which pivots the axis 76 of the beam 6. The second end of the axis 76 pivots in a bearing 78 arranged in the plate 14. The bearings 74 and 78 are shown schematically in Figure 9. In a conventional manner, the bearing 74 is generally associated with a bumper device known to those skilled in the art.

Les moyens de rรฉglage de l'รฉbat du balancier 6 sont obtenus, selon le principe de la prรฉsente invention, par dรฉformation du pont 64 engendrant une variation de l'inclination de la planche 70 et par consรฉquent une variation de la distance entre les paliers 74 et 78. Pour ce faire, la base 68 comprend deux parties distinctes 80 et 82 sรฉparรฉes par une zone intermรฉdiaire 84 dรฉfinissant une zone transversale de moindre rรฉsistance mรฉcanique permettant une dรฉformation localisรฉe entre les parties 80 et 82 de la base. La partie 80 qui est la plus รฉloignรฉe du palier 74 est fixรฉe rigidement ร  la platine 14 au moyen d'une vis de fixation 30. Cette premiรจre partie 80 est maintenue dans une position fixe et invariable relativement ร  la platine 14 lorsque la vis 30 est serrรฉe. La deuxiรจme partie 82 est รฉquipรฉe d'un dispositif permettant de varier la position de cette partie 82 relativement ร  la platine 14, ce qui engendre une dรฉformation du pont en particulier dans la rรฉgion intermรฉdiaire 84. Ainsi la position relative entre les deux parties 80 et 82 du pont 64 peut รชtre variรฉe, ce qui engendre un dรฉplacement de la planche 70 et en particulier du palier 74 relativement ร  la platine 14. Le moyen de dรฉformation du pont agissant sur la deuxiรจme partie 82 est semblable ร  celui dรฉcrit dans le cadre du premier mode de rรฉalisation. Il ne sera donc pas ร  nouveau dรฉcrit ici.The adjustment means of the balance wheel 6 are obtained, according to the principle of the present invention, by deformation of the bridge 64 causing a variation of the inclination of the board 70 and therefore a variation of the distance between the bearings 74 and 78. To do this, the base 68 comprises two distinct parts 80 and 82 separated by an intermediate zone 84 defining a transverse zone of lower mechanical strength allowing localized deformation between the parts 80 and 82 of the base. The portion 80 which is furthest from the bearing 74 is fixed rigidly to the plate 14 by means of a fixing screw 30. This first part 80 is held in a fixed and invariable position relative to the plate 14 when the screw 30 is tight. The second portion 82 is equipped with a device for varying the position of this portion 82 relative to the plate 14, which causes a deformation of the bridge, especially in the intermediate region 84. Thus the relative position between the two parts 80 and 82 of the bridge 64 can be varied, which generates a displacement of the board 70 and in particular of the bearing 74 relative to the plate 14. The means of deformation of the bridge acting on the second part 82 is similar to that described in the context of the first embodiment. It will not be described again here.

A la figure 10 est reprรฉsentรฉe un autre mode de rรฉalisation du moyen de dรฉformation du pont 4B. Cette alternative peut s'appliquer aux deux modes de rรฉalisation d'une piรจce d'horlogerie selon l'invention dรฉcrits ci-avant. Cependant, le mode de rรฉalisation reprรฉsentรฉ ร  la figure 10 correspond au cas d'un pont double selon le premier mode de rรฉalisation reprรฉsentรฉ ร  la figure 1. Le pont 4B comprend donc une base 18B similaire ร  la base 18 du mode de rรฉalisation de la figure 1.In Figure 10 is shown another embodiment of the deformation means of the bridge 4B. This alternative can be applied to the two embodiments of a timepiece according to the invention described above. However, the embodiment shown in FIG. 10 corresponds to the case of a double bridge according to the first embodiment shown in FIG. 1. The bridge 4B therefore comprises a base 18B similar to the base 18 of the embodiment of the figure 1.

Le mode de rรฉalisation de la figure 10 se distingue essentiellement de celui dรฉcrit ร  l'aide des figures prรฉcรฉdentes par le fait que la vis de fixation de la base 18B ร  la platine 14 n'est pas coaxiale ร  la vis 94 de rรฉglage de l'รฉbat du balancier. En effet, la vis 94, servant ร  la dรฉformation du pont 4B et ร  la variation de la position relative entre la base 18B et la platine 14, est agencรฉe entre la vis de serrage 32 et la planche 10 du pont 4B. On notera de suite que cette vis 94 peut รฉgalement รชtre agencรฉe de l'autre cรดtรฉ de la vis 32. La vis de rรฉglage 94 se distingue de la vis 34 des autres modes de rรฉalisation par le fait qu'elle ne prรฉsente pas de trou traversant et par le fait que son extrรฉmitรฉ supรฉrieur 96 est visible et accessible depuis la face supรฉrieure 46 du pont 4B alors que la vis de serrage 32 est mise en place dans le trou traversant 98 effectuรฉ dans la base 18B. L'extrรฉmitรฉ 96 de la vis 94 prรฉsente une fente 44B permettant de tourner cette vis 94 et donc de varier la distance entre la base 18B et la platine 14. Pour augmenter cette distance, l'horloger desserrera รฉvidemment la vis 32.The embodiment of FIG. 10 differs essentially from that described with the aid of the preceding figures in that the fixing screw of the base 18B to the plate 14 is not coaxial with the adjusting screw 94 the swing of the pendulum. Indeed, the screw 94, used for the deformation of the bridge 4B and the variation of the relative position between the base 18B and the plate 14, is arranged between the clamping screw 32 and the board 10 of the bridge 4B. Note that this screw 94 can also be arranged on the other side of the screw 32. The adjustment screw 94 differs from the screw 34 of the other embodiments in that it does not have a through hole and in that its upper end 96 is visible and accessible from the upper face 46 of the bridge 4B while the clamping screw 32 is placed in the through hole 98 made in the base 18B. The end 96 of the screw 94 has a slot 44B for rotating the screw 94 and thus to vary the distance between the base 18B and the plate 14. To increase this distance, the watchmaker will obviously loosen the screw 32.

Ce dernier mode de rรฉalisation du dispositif de rรฉglage de l'รฉbat du balancier prรฉsente certains avantages mais รฉgalement certains inconvรฉnients. L'actionnement du moyen de dรฉformation 94, formรฉ ici รฉgalement par un seul รฉlรฉment, peut รชtre effectuรฉ tout en laissant la vis de fixation 32 en place dans son trou 98. La vis de rรฉglage 94 est massive et donc moins onรฉreuse que la vis correspondante 34. Par contre, ce mode de rรฉalisation est plus encombrant et nรฉcessite notamment des dimensions de la base 18B supรฉrieures aux dimensions de la base 18 du premier mode de rรฉalisation.This last embodiment of the device for adjusting the balance of the hoist has certain advantages but also certain disadvantages. Actuation of the deformation means 94, formed here also by a single element, can be performed while leaving the fixing screw 32 in place in its hole 98. The adjusting screw 94 is solid and therefore less expensive than the corresponding screw 34. By cons, this embodiment is more bulky and in particular requires dimensions of the base 18B greater than the dimensions of the base 18 of the first embodiment.

Finalement, on mentionnera que dans un autre mode de rรฉalisation similaire au deuxiรจme mode reprรฉsentรฉ ร  la figure 9, la vis de rรฉglage 34 associรฉe ร  la vis de serrage 32 peut รชtre remplacรฉe par une seule vis semblable ร  la vis 94 reprรฉsentรฉe ร  la figure 10. Dans ce cas, le pont 64 sera usinรฉ de telle maniรจre que le rรฉglage de l'รฉbat du balancier nรฉcessite toujours et impรฉrativement de dรฉvisser la vis de rรฉglage 94 de maniรจre ร  รฉloigner le palier 74 du palier 76. Ainsi, la tรชte 36 de la vis 94 restera en appui contre la surface de la platine 14 par la rรฉsistance mรฉcanique due ร  la dรฉformation du pont 64. La section de la partie intermรฉdiaire 84 sera sรฉlectionnรฉe de maniรจre ร  permettre une dรฉformation de cette zone en dรฉvissant la vis de rรฉglage 94 tout en garantissant une force suffisante exercรฉe sur la tรชte 36 pour la maintenir plaquรฉe contre la platine 14 lorsque la vis 30 est serrรฉe.Finally, it will be mentioned that in another embodiment similar to the second embodiment shown in FIG. 9, the adjusting screw 34 associated with the clamping screw 32 can be replaced by a single screw similar to the screw 94 shown in FIG. In this case, the bridge 64 will be machined in such a way that the adjustment of the balance of the balance always and imperatively requires unscrewing the screw of adjustment 94 so as to distance the bearing 74 from the bearing 76. Thus, the head 36 of the screw 94 will rest against the surface of the plate 14 by the mechanical strength due to the deformation of the bridge 64. The section of the intermediate part 84 will be selected to allow deformation of this area by unscrewing the adjusting screw 94 while ensuring sufficient force exerted on the head 36 to keep it pressed against the plate 14 when the screw 30 is tightened.
