Abstract

The watch has a slit ring mounted to be locked axially and radially on a set of pinion/stem elements, and an axial locking unit for axially locking another set of the pinion/stem elements secured to the slit ring. The slit ring is mounted in a circular groove made in the former set of the pinion/stem elements. The axial locking unit is formed of an L-shaped arm which is engaged in a hollow e.g. circular groove, made in the latter set of the pinion/stem elements. The locking unit is formed of another slit ring connected to the former slit ring by a rigid arm.

Description

L'invention se rapporte au domaine de l'horlogerie. Elle concerne plus particulièrement une montre du type comportant un élément intérieur tournant muni d'un organe de commande actionnable depuis l'extérieur de la boîte.The invention relates to the field of watchmaking. It relates more particularly to a watch of the type comprising a rotating inner member provided with a control member operable from outside the box.

De telles montres sont connues et commercialisées. Il s'agit, classiquement, de montres de plongée comportant une lunette intérieure tournante. On peut également trouver des montres dont le cadran est tournant afin de créer un effet esthétique ou surprenant, ou des montres munie d'un polarisateur tournant inséré entre le cadran et la glace.Such watches are known and marketed. This is, conventionally, diving watches having a rotating inner bezel. One can also find watches whose dial is turning to create an aesthetic or surprising effect, or watches with a rotating polarizer inserted between the dial and the ice.

Quel que soit le type d'élément tournant, il est actionné à l'aide d'un organe de commande accessible depuis l'extérieur de la boîte. Ce type d'organe de commande est généralement formé d'une tige traversant radialement la boîte, d'une couronne fixée à l'extrémité extérieure de la tige et d'un pignon fixé à son extrémité intérieure. La fixation du pignon à la tige peut être réalisée de différentes façons, amovible ou non.Whatever the type of rotating element, it is actuated using a control member accessible from outside the box. This type of control member is generally formed of a rod passing radially through the box, a ring fixed to the outer end of the rod and a pinion fixed to its inner end. Fixing the pinion to the rod can be achieved in different ways, removable or not.

Un exemple de fixation amovible est présenté dans le document FR 059 626 . Le pignon y est solidaire d'une portion tubulaire fendue axialement de manière à former deux bras élastiques radialement. Un évidement est prévu à l'intérieur de la portion tubulaire, entre les deux bras. Par ailleurs, la tige est munie d'une tête engagée élastiquement dans ledit évidement, de manière à assurer le positionnement axial et radial du pignon sur la tige. Cette structure de l'organe de commande lui permet d'être monté et démonté aisément. Toutefois, son coût est élevé car l'usinage des bras élastiques, de l'évidement et de la tête, est complexe et nécessite un outillage sophistiqué.An example of removable attachment is presented in the document FR 059 626 . The pinion is secured to a tubular portion axially slotted so as to form two radially resilient arms. A recess is provided inside the tubular portion between the two arms. Furthermore, the rod is provided with a head resiliently engaged in said recess, so as to ensure the axial and radial positioning of the pinion on the rod. This structure of the control member allows it to be mounted and dismounted easily. However, its cost is high because the machining of the elastic arms, the recess and the head, is complex and requires sophisticated tools.

Un exemple de fixation non amovible du pignon à la tige est illustré sur la figure 1 qui représente une vue en coupe partielle d'une montre comportant un élément mobile.An example of non-removable attachment of the pinion to the rod is illustrated on the figure 1 which represents a partial sectional view of a watch comprising a movable element.

La montre représentée en figure 1 comporte classiquement une boîte 10 formée d'une carrure 12, d'une coiffe 14 et d'un fond 16 définissant ensemble un logement 18 dans lequel est monté un mouvement 20. Une glace 22 vient obturer la boîte 10 de façon étanche. Le mouvement 20 est surmonté d'un cadran 24. Un dégagement circulaire 26 réalisé dans la carrure 12 forme un épaulement 28 à hauteur du cadran 24. Une lunette tournante 30, interposée entre le cadran 24 et la glace 22, est partiellement logée dans le dégagement circulaire 26, qui assure son positionnement axial et son guidage en rotation. La face inférieure de la lunette tournante 30 comporte une première portion circulaire plate 32a disposée en regard de la périphérie du cadran 24 de façon à la masquer, et une deuxième portion circulaire plate 32b prenant appui sur l'épaulement 28. Elle comporte, en outre, une portion circulaire intermédiaire 32c située entre les première et deuxième portions plates 32a et 32b, et formant une denture de chant 34.The watch represented in figure 1 typically comprises a box 10 formed of a middle part 12, a cap 14 and a bottom 16 together defining a housing 18 in which is mounted a movement 20. An ice 22 closes the box 10 sealingly. The movement 20 is surmounted by a dial 24. A circular clearance 26 formed in the middle part 12 forms a shoulder 28 at the height of the dial 24. A rotating bezel 30, interposed between the dial 24 and the mirror 22, is partially housed in the circular clearance 26, which ensures its axial positioning and its rotation guide. The lower face of the rotating bezel 30 has a first flat circular portion 32a arranged opposite the periphery of the dial 24 so as to mask, and a second flat circular portion 32b bearing on the shoulder 28. It further comprises an intermediate circular portion 32c located between the first and second flat portions 32a and 32b, and forming a toothing 34.

Un organe de commande 36 vient actionner la lunette tournante 30. A cet effet, un trou 38 traverse radialement la carrure 12. Un tube intermédiaire 40 présentant un état de surface intérieur particulièrement soigné, est vissé à l'intérieur du trou 38. Une tige 42 d'axe longitudinal AA est montée à l'intérieur du tube 40 de façon que ses extrémités soient saillantes à l'extérieur et à l'intérieur de la boîte 10. Une couronne 44 est fixée à une première extrémité proximale, tandis qu'un pignon 46 est fixé à une deuxième extrémité distale. L'ensemble tige 42 - couronne 44 - pignon 46 forme l'organe de commande 36 de la lunette 30. Celui-ci est agencé dans la carrure 12 de sorte que le pignon 46 engrène avec la denture de chant 34. La rotation de la couronne 44 actionnée par l'utilisateur, entraîne ainsi la rotation de la lunette 30 à l'intérieur de la boîte 10.A control member 36 actuates the rotating bezel 30. For this purpose, a hole 38 passes radially through the middle part 12. An intermediate tube 40 having a particularly good internal surface state is screwed inside the hole 38. A rod 42 of longitudinal axis AA is mounted inside the tube 40 so that its ends protrude outside and inside the box 10. A ring 44 is fixed at a first proximal end, while a pinion 46 is attached to a second distal end. The stem assembly 42 - crown 44 - pinion 46 forms the control member 36 of the telescope 30. The latter is arranged in the middle part 12 so that the pinion 46 meshes with the edge toothing 34. The rotation of the crown 44 actuated by the user, thus causes the rotation of the telescope 30 inside the box 10.

Le pignon 46 est fixé à l'extrémité distale de la tige 42 par vissage et collage. Ce mode de fixation assure le positionnement axial et angulaire du pignon 46 par rapport à la tige 42, ce qui permet la transmission du mouvement de rotation de l'organe de commande 36 à la lunette 30. Toutefois, on observe qu'une telle fixation par vissage et collage est tellement forte qu'elle est pratiquement définitive. Lors d'un service, il est presque impossible de démonter l'organe de commande 36 sans briser la tige 42. Une solution simple à ce problème consiste à utiliser une tige 42 dont l'extrémité, à section carrée, est engagée dans un trou de pignon 46 également à section carrée. Le pignon 46 est ainsi bloqué angulairement. Le positionnement axial peut être réalisé à l'aide d'un circlips disposé à l'extrémité de la tige 42, dans une gorge située au voisinage immédiat du pignon 46, côté distal. Pour cela, la tige 42 doit être légèrement plus longue que dans le cas de la fixation par vissage - collage, ce qui n'est pas envisageable en raison d'un manque d'espace entre le pignon 46 et le mouvement 20.The pinion 46 is fixed to the distal end of the rod 42 by screwing and gluing. This method of fixing ensures the axial and angular positioning of the pinion 46 relative to the rod 42, which allows the transmission of the rotational movement of the control member 36 to the telescope 30. However, it is observed that such a fixation by screwing and gluing is so strong that it is virtually definitive. During a service, it is almost impossible to disassemble the control member 36 without breaking the rod 42. A simple solution to this problem is to use a rod 42 whose end, with a square section, is engaged in a hole pinion 46 also square section. The pinion 46 is thus angularly blocked. The axial positioning can be achieved using a circlip disposed at the end of the rod 42, in a groove located in the immediate vicinity of the pinion 46, distal side. For this, the rod 42 must be slightly longer than in the case of fixing by screwing - gluing, which is not possible because of a lack of space between the pinion 46 and the movement 20.

L'invention permet de pallier cette difficulté en proposant l'emploi d'une pièce de fixation disposée non pas côté mouvement, comme dans la solution proposée précédemment, mais côté carrure 12. Cette pièce de fixation est ancrée dans la tige 42 et le pignon 46 de manière à assurer le positionnement axial du pignon 46.The invention makes it possible to overcome this difficulty by proposing the use of a fastening part arranged not on the movement side, as in the solution proposed above, but on the middle side 12. This fastening piece is anchored in the rod 42 and the pinion 46 so as to ensure the axial positioning of the pinion 46.

Plus précisément, l'invention concerne une pièce d'horlogerie comportant une boîte et une glace définissant ensemble un logement pour un mouvement, et comportant, en outre, un élément mobile en rotation actionné par un organe de commande comprenant une tige d'axe longitudinal AA traversant radialement la boîte, une couronne montée sur une première extrémité proximale de la tige et un pignon monté solidaire en rotation sur une deuxième extrémité distale de la tige, caractérisé en ce que l'organe de commande est muni d'une pièce de fixation axiale du pignon sur la tige, disposée du côté proximal de la tige, la pièce de fixation comprenant :

  • une bague fendue montée bloquée axialement et radialement sur un premier des éléments pignon / tige, et
  • des moyens de blocage axial du deuxième des éléments tige / pignon, solidaires de la bague fendue,
More specifically, the invention relates to a timepiece comprising a box and an ice defining together a housing for a movement, and further comprising a rotatable member actuated by a control member comprising a longitudinal axis rod AA crossing the box radially, a crown mounted on a first proximal end of the rod and a pinion mounted rotatably mounted on a second distal end of the rod, characterized in that the control member is provided with an axial attachment piece of the pinion on the rod disposed on the proximal side of the stem, the fastener comprising:
  • a split ring mounted axially and radially locked on a first of the pinion / rod elements, and
  • axial locking means of the second of the rod / pinion elements, integral with the split ring,

Grâce à la pièce de fixation disposée du côté proximal de la tige 42, l'organe de commande 36 de l'élément tournant peut être démonté et remonté sans risque de cassure de la tige 42. D'autres caractéristiques et avantages de la présente invention ressortiront plus clairement de la description détaillée qui suit d'un exemple de réalisation d'une montre selon l'invention, cet exemple étant donné à titre purement illustratif et non limitatif seulement, en liaison avec les dessins annexés sur lesquels :

  • la figure 2 illustre une vue en coupe partielle d'une montre selon l'invention, et
  • la figure 3 représente une vue partielle éclatée d'un mode de réalisation avantageux d'un organe de commande présent sur la montre selon l'invention.
Thanks to the fastener disposed on the proximal side of the rod 42, the control member 36 of the rotating element can be disassembled and reassembled without risk of breakage of the rod 42. Other features and advantages of the present invention will emerge more clearly from the following detailed description of an exemplary embodiment of a watch according to the invention, this example being given for purely illustrative and non-limiting purposes only, in conjunction with the accompanying drawings in which:
  • the figure 2 illustrates a partial sectional view of a watch according to the invention, and
  • the figure 3 represents an exploded partial view of an advantageous embodiment of a control member present on the watch according to the invention.

La montre représentée en figure 2, comporte, à l'image de la montre représentée en figure 1, une boîte 10 formée d'une carrure 12, d'une coiffe 14 et d'un fond 16 définissant ensemble un logement 18 dans lequel est monté un mouvement 20. Une glace 22 vient obturer la boîte 10 de façon étanche. Le mouvement 20 est surmonté d'un cadran 24. Une lunette tournante 30 munie d'une denture de chant 34 est interposée entre le cadran 24 et la glace 22. Elle est actionnée par un organe de commande 36, comportant une tige 42, une couronne 44 et un pignon 46.The watch represented in figure 2 , has, like the watch represented in figure 1 , a box 10 formed of a middle part 12, a cap 14 and a bottom 16 together defining a housing 18 in which is mounted a movement 20. An ice 22 closes the box 10 sealingly. The movement 20 is surmounted by a dial 24. A rotating bezel 30 provided with a toothing 34 is interposed between the dial 24 and the mirror 22. It is actuated by a control member 36, comprising a rod 42, a crown 44 and pinion 46.

La montre représentée en figure 2 se distingue de la montre représentée en figure 1 en ce que le pignon 46 n'est pas vissé et collé à l'extrémité intérieure de la tige 42. En effet, le pignon 46 est monté solidaire en rotation à l'extrémité de la tige 42. Une pièce de fixation 48 amovible, située côté proximal de la tige 42, est ancrée dans la tige 42 et le pignon 46 de façon à assurer le positionnement axial de ce dernier. La pièce de fixation 48, est, par ailleurs, en appui sur le tube intermédiaire 40 de sorte qu'elle s'oppose à un déplacement axial de la tige 42 vers l'extérieur de la carrure 12.The watch represented in figure 2 differs from the watch shown in figure 1 in that the pinion 46 is not screwed and adhered to the inner end of the rod 42. In fact, the pinion 46 is rotatably mounted at the end of the rod 42. A removable fastener 48, located proximal side of the rod 42, is anchored in the rod 42 and the pinion 46 so as to ensure the axial positioning of the latter. The fixing piece 48 is, moreover, resting on the intermediate tube 40 so that it opposes axial displacement of the rod 42 towards the outside of the middle part 12.

La structure de l'organe de commande 36 équipant la montre selon l'invention, et, en particulier, le mode de fixation du pignon 46 sur la tige 42, apparaissent plus clairement sur la figure 3. L'extrémité distale 50 de la tige 42 est à section carrée. Une gorge circulaire 52 est pratiquée au voisinage de l'extrémité 50. Le pignon 46 comporte une portion dentée 54 destinée à coopérer avec la denture de chant 34, et une courte tige 56 dans laquelle est pratiquée une gorge circulaire 58. Le pignon 46 est percé d'un trou central 60 à section carrée. L'extrémité distale à section carrée 50 de la tige 42 est engagée dans le trou 60 à section carrée, de sorte que le pignon 46 est positionné angulairement et radialement par rapport à la tige 42. Bien entendu, toute autre forme de section permettant la transmission d'un couple, tel qu'une section triangulaire ou hexagonale, est susceptible d'être employée.The structure of the control member 36 equipping the watch according to the invention, and in particular the method of fixing the pinion 46 on the rod 42, appear more clearly on the figure 3 . The distal end 50 of the rod 42 is square section. A circular groove 52 is formed in the vicinity of the end 50. The pinion 46 has a toothed portion 54 intended to cooperate with the toothing 34, and a short rod 56 in which is formed a circular groove 58. The pinion 46 is pierced a central hole 60 with a square section. The distal end 50 of square section 50 of the rod 42 is engaged in the hole 60 of square section, so that the pinion 46 is positioned angularly and radially relative to the rod 42. Of course, any other form of section allowing the transmission of a torque, such as a triangular or hexagonal section, is likely to be employed.

La pièce de fixation 48 est formée d'une bague 62 et d'un bras rigide en L 64 solidaire de la bague 62 et s'étendant axialement depuis sa périphérie. La bague 62 est fendue de manière à présenter une certaine flexibilité radiale, la fente s'évasant légèrement vers l'extérieur. Cette caractéristique facilite le montage de la bague 62 par pression sur une pièce cylindrique. La bague 62 est montée dans la gorge 52 de sorte qu'elle est positionnée axialement et radialement sur la tige 42. Le bras rigide en L 64 est alors engagé dans la gorge 58, ce qui a pour effet de bloquer le pignon 46 axialement. Ainsi monté, l'organe de commande 36 peut remplir sa fonction de transmission du mouvement de rotation de la couronne 44 à la lunette tournante 30, tout en étant facilement démontable.The fastener 48 is formed of a ring 62 and a rigid L-shaped arm 64 integral with the ring 62 and extending axially from its periphery. The ring 62 is slotted so as to have a certain radial flexibility, the slot flaring slightly outwards. This feature facilitates the mounting of the ring 62 by pressure on a cylindrical piece. The ring 62 is mounted in the groove 52 so that it is positioned axially and radially on the rod 42. The rigid L-shaped arm 64 is then engaged in the groove 58, which has the effect of locking the pinion 46 axially. Thus mounted, the control member 36 can fulfill its function of transmitting the rotational movement of the ring 44 to the rotating bezel 30, while being easily removable.

Bien entendu, la montre selon l'invention ne se limite pas au mode de réalisation qui vient d'être décrit et diverses modifications et variantes simples peuvent être envisagées par l'homme du métier sans sortir du cadre de l'invention tel que défini par les revendications annexées.Of course, the watch according to the invention is not limited to the embodiment just described and various modifications and simple variants can be envisaged by the skilled person without departing from the scope of the invention as defined by the appended claims.

On notera, par exemple, que la gorge circulaire 58 pourrait être remplacée par une simple creusure dans laquelle est engagé le bras en L 64. Dans une deuxième variante, la pièce de fixation pourrait être formée de deux bagues du type de la bague 62, reliées ensemble par un bras rigide. Dans une troisième variante, l'extrémité 50 et la courte tige 56 pourraient être percées d'un trou perpendiculaire à l'axe AA de la tige 42. Le bras L 64 serait alors formé d'une portion rigide s'étendant axialement et d'une tige s'étendant radialement dans les trous pratiqués dans l'extrémité 50 et la tige 56. Enfin, on notera que l'organe de commande 36 peut actionner tout élément tournant, tel qu'une lunette, un cadran ou un polarisateur.It will be noted, for example, that the circular groove 58 could be replaced by a simple recess in which the L-shaped arm 64 is engaged. In a second variant, the fastener could be formed of two rings of the type of the ring 62, connected together by a rigid arm. In a third variant, the end 50 and the short rod 56 could be pierced with a hole perpendicular to the axis AA of the rod 42. The arm L 64 would then be formed of a rigid portion extending axially and from a rod extending radially in the holes formed in the end 50 and the rod 56. Finally, it will be noted that the control member 36 can actuate any rotating element, such as a bezel, a dial or a polarizer.
