Description

La présente invention a pour objet un mouvement d'horlogerie mécanique pour une pièce d'horlogerie telle qu'une montre-bracelet.The present invention relates to a mechanical clock movement for a timepiece such as a wristwatch.

Dans un mouvement d'horlogerie mécanique, pour un assemblage plus facile des composants du mouvement, l'échappement complet et l'organe réglant peuvent être montés prêts à fonctionner sur une plaquette ou un support appelé porte-échappement. Le porte-échappement est ensuite fixé sur le mouvement pour coopérer avec le rouage que l'organe réglant régule. Sur le porte-échappement peuvent notamment être fixés le pont d'échappement, le pont d'ancre (pour un échappement à ancre) et le coq.In a mechanical watch movement, for easier assembly of the components of the movement, the complete escapement and the regulating organ can be mounted ready to operate on a plate or a support called an escapement holder. The escapement holder is then attached to the movement to cooperate with the gear train that the regulating organ regulates. On the escapement holder can in particular be fixed the escapement bridge, the anchor bridge (for an anchor escapement) and the balance cock.

Le document EP 2802942 et le document WO 2008/101802 décrivent, chacun, un organe réglant dit incliné, c'est-à-dire que dans sa position de service, l'axe de l'organe réglant n'est pas parallèle aux axes des mobiles du rouage qu'il régule ou encore que l'organe réglant n'est pas parallèle audit rouage. L'inclinaison de l'organe réglant permet en effet de compenser en partie les effets de la gravité sur ledit organe. Or, avec un organe réglant incliné, les réglages effectués sur le porte-échappement lors du montage de ses composants (échappement et organe réglant) et notamment le partagement de la roue d'échappement et de l'ancre, ont une influence directe sur la coopération entre l'échappement et le rouage, et donc sur la marche du mouvement, puisque le mobile d'échappement est incliné par rapport au rouage du mouvement.The document EP 2802942 and the document WO 2008/101802 each describe a so-called inclined regulating organ, that is to say that in its service position, the axis of the regulating organ is not parallel to the axes of the mobiles of the gear train that it regulates or that the regulating organ is not parallel to said gear train. The inclination of the regulating member makes it possible to partially compensate for the effects of gravity on said member. However, with an inclined regulating organ, the adjustments made to the escapement holder during assembly of its components (escapement and regulating organ) and in particular the division of the escape wheel and the lever, have a direct influence on the cooperation between the escapement and the gear train, and therefore on the rate of the movement, since the escapement wheel set is inclined with respect to the gear train of the movement.

De plus, avec un organe réglant incliné, l'utilisation d'un pignon d'échappement dont les dents ont un profil variable sur sa hauteur permet d'améliorer les conditions d'engrènement, notamment la répartition des efforts entre les dents dudit pignon d'échappement et du mobile d'axe non parallèle avec lequel il coopère. Cependant, avec ce profil variable, l'influence du partagement des composants de l'échappement sur la coopération de l'échappement et du rouage du mouvement est encore plus grande.In addition, with an inclined regulating member, the use of an escapement pinion whose teeth have a variable profile over its height makes it possible to improve the meshing conditions, in particular the distribution of the forces between the teeth of said pinion. escapement and the non-parallel axis mobile with which it cooperates. However, with this variable profile, the influence of the sharing of escapement components on the cooperation of the escapement and the movement train is even greater.

Avec un organe réglant incliné, il serait donc très avantageux de pouvoir régler simplement la position du porte-échappement par rapport au rouage du mouvement une fois que la position de l'échappement et de l'organe réglant, et notamment le partagement de l'échappement et du mobile d'ancre, ont été réglés sur le porte-échappement.With an inclined regulating organ, it would therefore be very advantageous to be able to simply adjust the position of the escapement holder relative to the gear train of the movement once the position of the escapement and of the regulating organ, and in particular the division of the escapement and anchor mobile, have been adjusted on the escapement holder.

Le but de la présente invention est donc de proposer un mouvement d'horlogerie dans lequel la position du porte-échappement par rapport au rouage de finissage du mouvement peut être réglée par une opération simple, ledit porte-échappement portant un échappement et un organe réglant incliné par rapport au rouage qu'il régule.The object of the present invention is therefore to propose a watch movement in which the position of the escapement holder relative to the going train of the movement can be adjusted by a simple operation, said escapement holder carrying an escapement and a regulating organ inclined with respect to the gear train it regulates.

Le mouvement d'horlogerie selon l'invention est un mouvement mécanique destiné à équiper une pièce d'horlogerie telle qu'une montre-bracelet. Le mouvement d'horlogerie selon l'invention comprend notamment un porte-échappement 1 destiné à porter un échappement complet 3 et un organe réglant 4 et à être fixé sur le bâti 2 du mouvement.The timepiece movement according to the invention is a mechanical movement intended to equip a timepiece such as a wristwatch. The timepiece movement according to the invention comprises in particular an escapement holder 1 intended to carry a complete escapement 3 and a regulating member 4 and to be fixed on the frame 2 of the movement.

Selon l'invention, le porte-échappement 1 est conformé pour qu'une fois monté sur le bâti 2 du mouvement, l'organe réglant 4 soit incliné par rapport au rouage du mouvement qu'il régule et sa position réglable par rapport à ce dernier.According to the invention, the escapement holder 1 is shaped so that, once mounted on the frame 2 of the movement, the regulating member 4 is inclined with respect to the gear train of the movement that it regulates and its position adjustable with respect to this latest.

Plus précisément et selon la forme d'exécution illustrée, le porte-échappement 1 comprend une première portion 1.1 et une seconde portion 1.2 dite portion inclinée 1.2, définissant deux plans non-parallèles entre eux. Le mobile d'échappement 3 ainsi que l'organe réglant 4 sont pivotés sur la portion inclinée 1.2 du porte-échappement 1.More precisely and according to the illustrated embodiment, the escapement holder 1 comprises a first portion 1.1 and a second portion 1.2 called the inclined portion 1.2, defining two non-parallel planes between them. The escapement wheel set 3 as well as the regulating organ 4 are pivoted on the inclined portion 1.2 of the escapement holder 1.

Le mobile d'échappement 3 comprend une roue d'échappement 3.1 solidaire d'un pignon d'échappement 3.2 et une ancre 3.3, tous pivotés entre la portion inclinée 1.2 du porte-échappement 1 et un pont d'échappement 3.4. Le pont d'échappement 3.4 est positionné sur la portion inclinée 1.2 du porte-échappement 1 au moyen de deux plots ou goupilles 3.6 et fixé au moyen de trois vis 3.5. Dans la suite, le terme « plot » seul sera utilisé pour désigner indifféremment un plot ou une goupille. Dans la forme d'exécution illustrée, le pignon d'échappement 3.2 présente une section variable (conique). En variante, ledit pignon d'échappement pourrait être droit (section constante).The escapement wheel set 3 comprises an escapement wheel 3.1 secured to an escapement pinion 3.2 and an anchor 3.3, all pivoted between the inclined portion 1.2 of the escapement holder 1 and an escapement bridge 3.4. The exhaust bridge 3.4 is positioned on the inclined portion 1.2 of the exhaust holder 1 by means of two studs or pins 3.6 and fixed by means of three screws 3.5. In the following, the term “stud” alone will be used to designate either a stud or a pin. In the illustrated embodiment, the escapement pinion 3.2 has a variable section (conical). As a variant, said escape pinion could be straight (constant section).

L'organe réglant 4 comprend quant à lui un balancier 4.1 et un spiral 4.2 et est pivoté entre la portion inclinée 1.2 du porte-échappement 1 et un pont de balancier 4.3. Le pont de balancier 4.3 est positionné sur la portion inclinée 1.2 du porte-échappement 1 au moyen de deux plots 4.4 et fixé au moyen d'une vis 4.5 (visible uniquement sur la figure 1).The regulating organ 4 comprises a balance wheel 4.1 and a hairspring 4.2 and is pivoted between the inclined portion 1.2 of the escapement holder 1 and a balance bridge 4.3. The balance bridge 4.3 is positioned on the inclined portion 1.2 of the escapement holder 1 by means of two studs 4.4 and fixed by means of a screw 4.5 (visible only on the figure 1 ).

Le porte-échappement 1 est destiné à être fixé sur le bâti 2 du mouvement selon l'invention de sorte que le pignon d'échappement 3.2 engrène avec la roue de seconde 5 du rouage de finissage (non illustré) dudit mouvement, pour la régulation de ce rouage de finissage.The escapement holder 1 is intended to be fixed on the frame 2 of the movement according to the invention so that the escapement pinion 3.2 meshes with the second wheel 5 of the going train (not illustrated) of said movement, for regulation of this finishing gear train.

Selon l'invention, le mouvement d'horlogerie comprend des moyens de réglage permettant de régler et fixer la position du porte-échappement 1 sur le bâti 2 et notamment de régler la pénétration des dents du pignon d'échappement 3.2 avec les dents de la roue de seconde 5.According to the invention, the timepiece movement comprises adjustment means making it possible to adjust and fix the position of the escapement holder 1 on the frame 2 and in particular to adjust the penetration of the teeth of the escape pinion 3.2 with the teeth of the second wheel 5.

Dans la forme d'exécution illustrée, les moyens de réglage sont agencés pour faire pivoter le porte-échappement 1 autour d'un plot recevant une première vis de serrage 6.1, le contour de ce plot guidant un premier trou 6.4 de la première portion 1.1 du porte échappement 1 et la première vis de serrage 6.1 étant vissée dans le bâti 2 du mouvement. Les moyens de réglages comprennent en outre un excentrique 6.2 traversant un premier trou oblong 6.5 de la première portion 1.1 du porte-échappement 1 et fixé dans le bâti 2 du mouvement ainsi qu'une seconde vis de serrage 6.3 traversant un second trou oblong 6.6 de la première portion 1.1 du porte-échappement 1 et fixé dans le bâti 2 du mouvement.In the illustrated embodiment, the adjustment means are arranged to cause the escapement holder 1 to pivot around a stud receiving a first clamping screw 6.1, the contour of this stud guiding a first hole 6.4 of the first portion 1.1 of the escapement holder 1 and the first clamping screw 6.1 being screwed into the frame 2 of the movement. The adjustment means further comprise an eccentric 6.2 passing through a first oblong hole 6.5 of the first portion 1.1 of the escapement holder 1 and fixed in the frame 2 of the movement as well as a second clamping screw 6.3 passing through a second oblong hole 6.6 of the first portion 1.1 of the escapement holder 1 and fixed in the frame 2 of the movement.

Le montage et le réglage de l'échappement 3 et de l'organe réglant 4 sur le mouvement selon l'invention sont décrits ci-après. L'échappement 3 et l'organe réglant 4 sont d'abord montés sur la portion inclinée 1.2 du porte-échappement 1 et leur position relative réglée sur ledit porte-échappement 1 hors du mouvement (sur un portage séparé par exemple). En particulier, le partagement de la roue d'échappement 3.2 et de l'ancre 3.3 peut être réglé lors du montage des éléments sur le porte-échappement 1 avant de fixer ledit porte-échappement 1 sur le mouvement selon l'invention.The assembly and adjustment of the escapement 3 and of the regulating member 4 on the movement according to the invention are described below. The escapement 3 and the regulating member 4 are first mounted on the inclined portion 1.2 of the escapement holder 1 and their relative position adjusted on said escapement holder 1 outside the movement (on a separate bearing for example). In particular, the distribution of the escape wheel 3.2 and the anchor 3.3 can be adjusted when mounting the elements on the escapement holder 1 before fixing said escapement holder 1 on the movement according to the invention.

Le porte-échappement 1 est ensuite positionné et fixé sur le bâti 2 du mouvement notamment au moyen des première et seconde vis de serrage 6.1, 6.3 et de l'excentrique 6.2. Pour régler la position du porte-échappement 1 sur le mouvement selon l'invention et donc la pénétration des dents du pignon d'échappement 3.1 avec la roue de seconde 5, on commence par desserrer la seconde vis de serrage 6.3. Le porte-échappement 1 peut alors être pivoté autour du plot qui reçoit la première vis de serrage 6.1, guidé par l'excentrique 6.2, jusqu'à la position voulue du pignon d'échappement 3.2 par rapport à la roue de seconde 5. La seconde vis de serrage 6.3 est ensuite resserrée pour fixer la position du porte-échappement 1 sur le bâti 2.The escapement holder 1 is then positioned and fixed on the frame 2 of the movement in particular by means of the first and second clamping screws 6.1, 6.3 and the eccentric 6.2. To adjust the position of the escapement holder 1 on the movement according to the invention and therefore the penetration of the teeth of the escapement pinion 3.1 with the second wheel 5, one begins by loosening the second clamping screw 6.3. The escapement holder 1 can then be pivoted around the stud which receives the first clamping screw 6.1, guided by the eccentric 6.2, until the desired position of the escapement pinion 3.2 with respect to the second wheel 5. The second tightening screw 6.3 is then tightened to fix the position of the escapement holder 1 on the frame 2.

De préférence, les moyens de réglage sont agencés pour permettre d'ajuster la distance entre les axes du pignon d'échappement 3.2 et de la roue de seconde 5 d'environ +/- 0,2 mm, de manière encore plus privilégiée et comme illustrée aux figures d'environ, +/- 0,1 mm.Preferably, the adjustment means are arranged to make it possible to adjust the distance between the axes of the escapement pinion 3.2 and of the second wheel 5 by approximately +/- 0.2 mm, in an even more privileged manner and as shown in figures approximately, +/- 0.1 mm.

La forme d'exécution ci-dessus a été décrite à titre d'exemple et des variantes sont bien entendu possibles sans sortir du cadre de l'invention telle que définie dans les revendications.The above embodiment has been described by way of example and variants are of course possible without departing from the scope of the invention as defined in the claims.

Dans la forme d'exécution illustrée, les moyens de réglage sont agencés pour permettre la rotation du porte-échappement autour d'un point de pivot par rapport au bâti 2. En variante, les moyens de réglage pourraient permettre la translation du porte-échappement ou toute combinaison d'une translation et d'une rotation.In the illustrated embodiment, the adjustment means are arranged to allow the rotation of the escapement holder around a pivot point relative to the frame 2. Alternatively, the adjustment means could allow the translation of the escapement holder or any combination of translation and rotation.

De plus, selon l'invention, l'excentrique 6.2 pourrait être remplacé par tout organe de réglage approprié comme une vis sans fin ou un élément s'appuyant sur une came, tandis que les première et/ou seconde vis de serrage 6.1, 6.3 pourraient être remplacées par tout organe de serrage approprié.In addition, according to the invention, the eccentric 6.2 could be replaced by any appropriate adjustment member such as a worm or an element resting on a cam, while the first and/or second tightening screws 6.1, 6.3 could be replaced by any appropriate tightening device.

De même, dans la forme d'exécution illustrée, le déplacement du porte-échappement 1 pour son réglage se fait dans un plan essentiellement parallèle au plan de la roue de seconde 5 et du rouage de finissage du mouvement ou encore dans un plan essentiellement parallèle au plan d'appui du porte-échappement sur le mouvement (ledit plan d'appui est parallèle au plan de la première portion 1.1 dans la forme d'exécution illustrée). De manière générale, le mouvement et le porte-échappement du mouvement selon l'invention sont agencés pour permettre le réglage de la position du porte-échappement une fois monté sur le mouvement dans un plan non parallèle au plan de l'échappement 3 et de l'organe réglant 4. En effet, un déplacement du porte-échappement dans un plan de réglage non parallèle au plan de l'échappement permet de régler la pénétration du pignon d'échappement avec la roue de seconde (distance entre les axes non parallèles) tout en limitant les modifications sur la hauteur relative entre ledit pignon d'échappement et la roue de seconde. Une variation de la hauteur relative est notamment problématique avec un pignon d'échappement conique (section non constante).Similarly, in the illustrated embodiment, the movement of the escapement holder 1 for its adjustment takes place in a plane essentially parallel to the plane of the second wheel 5 and of the movement finishing train or even in a plane essentially parallel to the support plane of the escapement holder on the movement (said support plane is parallel to the plane of the first portion 1.1 in the illustrated embodiment). In general, the movement and the escapement holder of the movement according to the invention are arranged to allow adjustment of the position of the escapement holder once mounted on the movement in a plane not parallel to the plane of the escapement 3 and of the regulating organ 4. Indeed, a displacement of the escapement holder in an adjustment plane not parallel to the escapement plane makes it possible to adjust the penetration of the escapement pinion with the second wheel (distance between the non-parallel axes ) while limiting modifications to the relative height between said pinion escapement and the seconds wheel. A variation of the relative height is particularly problematic with a conical escapement pinion (non-constant section).

On réalise ainsi un mouvement d'horlogerie comprenant un porte-échappement qui permet de porter un échappement et un organe réglant incliné par rapport à un rouage du mouvement et dont le réglage de la position sur le mouvement est simplifié. En effet, comme avec un porte échappement et un échappement traditionnel (non incliné), l'ensemble échappement et organe-réglant peut être assemblé et réglé hors du mouvement directement sur le porte-échappement. Le porte-échappement peut être ensuite placé sur le bâti et sa position réglée par une opération simple pour garantir la meilleure pénétration du pignon d'échappement et de la roue de seconde, sans risquer de devoir régler à nouveau le partagement ou un autre paramètre de l'échappement ou de l'organe réglant sur le porte-échappement. De plus, le réglage du porte-échappement permet également en une opération simple d'absorber les variations des tolérances des différents éléments du mouvement (bâti, ponts,...).A watch movement is thus produced comprising an escapement holder which makes it possible to carry an escapement and a regulating member inclined with respect to a gear train of the movement and the adjustment of the position of which on the movement is simplified. Indeed, as with an escapement holder and a traditional escapement (not inclined), the escapement and regulating organ assembly can be assembled and adjusted outside the movement directly on the escapement holder. The escapement holder can then be placed on the frame and its position adjusted by a simple operation to guarantee the best penetration of the escapement pinion and the seconds wheel, without the risk of having to re-adjust the division or another parameter of the escapement or the regulating organ on the escapement holder. In addition, the adjustment of the escapement holder also makes it possible, in a simple operation, to absorb the variations in the tolerances of the various elements of the movement (frame, bridges, etc.).

Claims (9)

  1. Timepiece movement comprising an escapement (3), a regulating member oscillating in a given plane (4) arranged to regulate a finishing going train (5) of the movement and an escapement support (1) bearing the regulating member (4) and the escapement (3) and intended to be fixed to the movement such that, once fixed to the movement, the regulating member (4) is not in parallel with the plane of the finishing going train (5) regulated thereby, said movement further comprising regulation means shaped to allow the regulation of the position of the escapement support (1) on the movement with respect to the finishing going train (5), the regulation means being arranged to allow the translational and/or rotational displacement of the escapement support (1), and the regulation means comprising a regulation member (6.2) to guide the displacement of the escapement support (1) as its position is being regulated and at least one locking member (6.1, 6.3) to lock the escapement support (1) in a given position on the movement with respect to the finishing going train (5), said regulation member comprising an eccentric, an endless screw or an element bearing against a cam.
  2. Timepiece movement as claimed in claim 1, characterised in that the regulation means are arranged such that the position of the escapement support (1) on the movement with respect to the finishing going train (5) can be regulated in a plane which is not in parallel with the plane of the regulating member (4), preferably in a plane substantially in parallel with the bearing plane of the escapement support (1) on the movement.
  3. Timepiece movement as claimed in any one of the preceding claims, characterised in that the escapement support (1) comprises a first portion (1.1) and a second portion (1.2) forming a non-zero angle therebetween, the second portion (1.2) bearing the escapement (3) and the regulating member (4), the escapement support (1) being fixed to the movement via the first portion (1.1).
  4. Timepiece movement as claimed in any one of the preceding claims, characterised in that the locking member is a locking screw (6.1, 6.3).
  5. Timepiece movement as claimed in any one of the preceding claims, characterised in that the regulating member (4) is of the balance-hairspring type (4.1, 4.2); and in that the escapement (3) comprises an escapement wheel (3.1) fixedly attached to an escapement pinion (3.2) and engaged with watch pallets (3.3), the escapement pinion (3.2) being arranged to cooperate with the finishing going train (5) of the movement.
  6. Timepiece movement as claimed in the preceding claim 5, characterised in that the escapement pinion (3.2) has a constant cross-section.
  7. Timepiece movement as claimed in claim 5, characterised in that the escapement pinion (3.2) has a variable cross-section.
  8. Timepiece movement as claimed in any one of claims 5 to 7, characterised in that the movement and the escapement support (1) are shaped to allow in particular the regulation of the penetration of the escapement pinion (3.2) with a mobile (5) of the finishing going train of the movement with which it meshes.
  9. Timepiece comprising a timepiece movement as claimed in any one of the preceding claims.
