Definitions
- the present invention relates to a timepiece control device comprising a control rod that can be actuated in rotation and in traction, and at least one push button, close to the control rod.
- the control rod comprises a first locking system in rotation and traction provided with a locking ring rotatably mounted with reference to the control rod and about the axis defined by the latter, said first locking system being able to occupy a locked position, in which the rotation and / or traction of the control rod is blocked.
- the document FR1471802 proposes a pusher equipped with a ring screwed to the periphery of the pusher and able to be moved longitudinally with reference to the pusher.
- the ring can be positioned so as to abut against the middle part of the watch and thus prevent any actuation of the pusher.
- the document EP1280023 discloses a locking system of a winding stem by means of a compression wrench screwed onto the tube which passes through the box through a bore formed therein.
- the present invention aims to provide an improved system for securing the control members of a watch, particularly for diving in great depths.
- the invention relates to a control device for locking in rotation and in traction a control rod according to claim 1.
- the figure 1 illustrates a timepiece control device according to a preferred embodiment of the invention.
- This device comprises a control rod that can be actuated in rotation and in traction.
- This control rod is typically a winding stem, capable of occupying several axial positions, and allowing the user to arm a mainspring energizing the movement and adjust the display of various time information.
- the winding stem comprises, conventionally, a ring 1 mounted in tension on a tube 9, the latter passing through a middle of a watch case, via an opening in which it is fixed rigidly and sealingly.
- the ring 1 is integrally arranged with a cap 2.
- a threaded pin 14 is kinematically connected, on the one hand to the movement and, on the other hand, to the ring via a pinched tube 6 and a spring 3. This connection does not part of the invention and being known to those skilled in the art, it will not be described in detail.
- the periphery of the tube 9 comprises, consecutively to the part intended to receive the cap 2, on the opposite side to the ring 1, a portion provided with a male-like shape structure 42.
- this form structure male type 42 may be a toothing. It is fixed with reference to the device or the watch case when the device is assembled.
- a stitched ring 13 is mounted on this portion.
- the stitched ring 13 has, at its inside diameter, a female-type shape structure 44, of shape and size corresponding to the male-like shape structure 42.
- the correspondence of the shape structures 42 and 44 allows a displacement relative translation in translation of the stitched ring 13, while serving as guide means thereof.
- the dimensions of the shape structure 44 are defined with reference to the position of the cap 2 and the dimensions of the portion provided with the structure 42, so that the stitched ring 13 can move in translation along a predefined stroke.
- the stitched ring 13 comprises, in addition to the female-type shape structure 44, an annular zone 46 of greater diameter than the structure 44, these two parts being connected by a shoulder 48.
- the annular zone 46 ends, at its free end, with a flank 50 of generally frustoconical shape, narrowing toward the crown.
- a flank 50 of generally frustoconical shape, narrowing toward the crown.
- this sidewall is formed a plurality of through openings, typically of circular shape, in each of which takes place a ball 5, typically made of steel or other equivalent material, for example ceramic.
- the balls 5 are thus housed in these openings, and cooperate on the one hand with compartments 39, visible on the figure 8 and made in the wall of the cap 2, and dimensioned to accommodate each a single ball 5.
- the compartments 39 have an oblong shape allowing the balls 5 to have a game along the longitudinal axis with reference to the compartments, between positions in which the center of the balls is located at the points referenced 64 or 66.
- the balls 5 cooperate with a frustoconical rim 52 of a bearing ring 11, the direction of which is oriented so as to direct the balls 5 towards the compartments 39.
- the support ring 11 is mounted integral with a locking ring 8 which will be described in detail below. Its inside diameter is slightly more large than the outside diameter of the stitched ring 13, so that, in its translational movements mentioned above, the stitched ring 13 moves inside the locking ring 8. As will be detailed below, it is already understood that the translational movements of the stitched ring 13 can induce a pressure of the balls 5 in their housing.
- the support ring 11 is thus mounted integral with the locking ring 8.
- the latter comprises a gripping zone at its periphery, formed for example by raised striations. It is rotatably mounted on the tube 9.
- the locking ring 8 comprises a series of variations of inner diameter, in order to adapt to the shape of the stitched ring 13, while participating in guiding the movements of the latter. Between zones of different diameters, the locking ring 8 has flanges, one of which 54 is particularly located opposite the shoulder of the stitched ring.
- the locking ring 8 comprises, on the upper face of the flange 54, that is to say on its face on the side of the ring, a plurality of studs 7 projecting. These are intended to cooperate with a first cam path 56 located on the underside of the shoulder 48 of the stitched ring 13.
- the first cam path 56 has at least a first and a second level.
- the first cam path 56 comprises as many first and second level successions as the locking ring 8 comprises studs 7. These are angularly distributed so as to co-operate in a coordinated manner with either the first level or the second level. the cam path.
- level is meant surfaces located at different distances from the box when the control device is mounted. The transition between the levels is preferably progressively.
- the studs 7 are in free support on the first cam path 56.
- the pads 7 slide on the first cam path 56 and thus press on the stitched ring 13.
- the latter then moves in translation, guided by the cooperation of the male-shaped structures 42 and female 44.
- This has the advantage of avoiding rotating the crown.
- the balls 5 play the role of friction member and are thus pressed into their housing and particularly against the cap 2 and its compartments 39. This pressure creates a strong friction on the cap and, indirectly, on the ring 1, which is immobilized.
- the ring 1 may have a slight clearance in the direction of a pressure translation.
- the center of the balls is located at point 66, allowing a slight clearance to point 64.
- the crown is immobilized in tension.
- the crown is also immobilized in rotation. This defines a first locking system in rotation and traction of the control rod. It will be noted that, by adapting the shape of the compartments 39, the ring 1 could be completely locked in both directions of translation, that is to say in pressure and in tension.
- the locking ring 8 may comprise a second cam path 58 on its underside, that is to say on its face, when the control device is mounted on the side of the watch case.
- this second cam path 58 has at least a first and a second level, the utility of which will appear later. Level is also understood to mean surfaces located at different distances from the box when the control device is mounted. The transition between levels is preferably gradual, as shown by the figure 4 .
- the control device may also comprise at least one first latch 30, intended to be pivotally mounted in the watch case.
- This rocker comprises a first end 30a maintained pressed against the second cam path 58 and a second end 30b may be in contact with a pusher 25 located in the vicinity of the control rod, to block the translation of the latter.
- the pusher 25 not being a direct part of the invention, it will not be described in detail.
- the latch 30 is held in contact with the second cam path 58 by a movable finger 28, subjected to the action of a spring 27 and mounted in the middle part 40 of the watch case.
- the shape of the first end 30a is defined to promote its cooperation and sliding on the second cam path 58.
- the first and second levels of the latter define a first and a second position of the latch 30.
- the second end 30b of the rocker 30 may have a flat surface 30c ending in a bearing zone 30d.
- the latch 30 When the latch 30 is in its first position, it leaves free the pusher 25.
- the flat surface 30c is substantially parallel to the inner face of the pusher 25 and neither this flat surface 30c nor the support zone 30d interferes with the stroke of the pusher.
- the latch 30 When the latch 30 is in its second position, the pusher 25 is blocked.
- the pusher is in the extended position, the bearing zone is in contact with the pusher and locks it in this position. The passage from one to the other of these positions is done by rotation of the locking ring 8, as illustrated on the Figures 4a and 4b .
- the locking ring 8 is rotatably mounted on the tube 9. Its rotation is done without screwing or axial displacement of itself. To improve the operation of the control device and to allow the user to determine whether the locking system is in the locked or free position, the position of the locking ring 8 is indexed. In addition and preferably, its rotational movements are limited between two extreme positions.
- the locking ring 8 comprises, in the vicinity of the second cam path 58, a guide groove 60 in the form of an arc of a circle, inside which a ball of a ball catch 32 engages ( figure 6 ).
- the ends of the groove 60 may comprise a circular recess 62 in which the ball of the pawl 32 may partially engage, in order to mark by a notch the extreme positions of the locking ring 8.

Description
La présente invention concerne un dispositif de commande de pièce d'horlogerie comprenant une tige de commande susceptible d'être actionnée en rotation et en traction, et au moins un bouton poussoir, voisin de la tige de commande. La tige de commande comporte un premier système de blocage en rotation et en traction doté d'une bague de blocage montée à rotation en référence à la tige de commande et autour de l'axe défini par celle-ci, ledit premier système de blocage étant susceptible d'occuper une position bloquée, dans laquelle la rotation et/ou la traction de la tige de commande est bloquée.The present invention relates to a timepiece control device comprising a control rod that can be actuated in rotation and in traction, and at least one push button, close to the control rod. The control rod comprises a first locking system in rotation and traction provided with a locking ring rotatably mounted with reference to the control rod and about the axis defined by the latter, said first locking system being able to occupy a locked position, in which the rotation and / or traction of the control rod is blocked.
De tels dispositifs sont généralement utilisés dans des montres de plongée. En effet, lors de plongées à de grandes profondeurs, la pression exercée sur les organes de commande, c'est-à-dire sur la tige de remontoir ou sur des poussoirs dont serait munie la montre, est très importante. Outre les problèmes d'étanchéité, la pression peut engendrer l'actionnement intempestif des poussoirs.Such devices are generally used in diving watches. Indeed, during dives at great depths, the pressure exerted on the control members, that is to say, on the winding stem or on pushers which would be provided with the watch, is very important. In addition to the sealing problems, the pressure can cause inadvertent actuation of the pushers.
Des systèmes de blocage des mouvements des poussoirs ou des tiges de remontoir ont été décrits dans plusieurs demandes de brevet. Notamment, le document
Le document
La présente invention a pour but de proposer un système amélioré de sécurisation des organes de commande d'une montre, notamment en vue de plongées dans de grandes profondeurs.The present invention aims to provide an improved system for securing the control members of a watch, particularly for diving in great depths.
De façon plus précise, l'invention concerne un dispositif de commande permettant de bloquer en rotation et en traction une tige de commande selon la revendication 1.More specifically, the invention relates to a control device for locking in rotation and in traction a control rod according to

Comme on peut le voir également sur la
Le pourtour du tube 9 comporte, consécutivement à la partie destinée à recevoir la coiffe 2, du côté opposé à la couronne 1, une portion munie d'une structure de forme de type mâle 42. Typiquement, cette structure de forme de type mâle 42 peut être une denture. Elle est fixe en référence au dispositif ou à la boite de montre lorsque le dispositif est assemblé.The periphery of the tube 9 comprises, consecutively to the part intended to receive the
Une bague brochée 13 est montée sur cette portion. La bague brochée 13 comporte, au niveau de son diamètre intérieur, une structure de forme de type femelle 44, de forme et de dimensions correspondant à la structure de forme de type mâle 42. La correspondance des structures de forme 42 et 44 permet un déplacement relatif en translation de la bague brochée 13, tout en servant de moyen de guidage de celle-ci. Les dimensions de la structure de forme 44 sont définies en référence à la position de la coiffe 2 et aux dimensions de la portion munie de la structure 42, de manière à ce que la bague brochée 13 puisse se déplacer en translation selon une course prédéfinie.A stitched
Plus précisément, la bague brochée 13 comporte, outre la structure de forme de type femelle 44, une zone annulaire 46 de diamètre supérieur à la structure 44, ces deux parties étant reliées par un épaulement 48.More precisely, the stitched
La zone annulaire 46 se termine, au niveau de son extrémité libre, par un flanc 50 de forme générale tronconique, se rétrécissant en direction de la couronne. Dans ce flanc est ménagée une pluralité d'ouvertures traversantes, typiquement de forme circulaire, dans chacune desquelles prend place une bille 5, typiquement réalisée en acier ou un autre matériau équivalent, par exemple en céramique.The
Les billes 5 sont ainsi logées dans ces ouvertures, et coopèrent d'une part avec des compartiments 39, visibles sur la
La bague d'appui 11 est montée solidaire d'une bague de blocage 8 qui va être décrite en détails ci-après. Son diamètre intérieur est légèrement plus grand que le diamètre extérieur de la bague brochée 13, de sorte que, dans ses déplacements en translation mentionnés ci-dessus, la bague brochée 13 se déplace à l'intérieur de la bague de blocage 8. Comme on le détaillera ci-après, on comprend déjà que les déplacements en translation de la bague brochée 13 peuvent induire une pression des billes 5 dans leur logement.The
La bague d'appui 11 est donc montée solidaire de la bague de blocage 8. Cette dernière comprend une zone de préhension à sa périphérie, formée par exemple de stries en relief. Elle est montée à rotation sur le tube 9. La bague de blocage 8 comprend une série de variations de diamètre intérieur, afin de s'adapter à la forme de la bague brochée 13, tout en participant au guidage des déplacements de cette dernière. Entre des zones de diamètres différents, la bague de blocage 8 présente des rebords, dont un 54 est particulièrement situé en regard de l'épaulement de la bague brochée.The
La bague de blocage 8 comprend, sur la face supérieure du rebord 54, c'est-à-dire sur sa face située du côté de la couronne, une pluralité de plots 7 en saillie. Ces derniers sont destinés à coopérer avec un premier chemin de came 56 situé sur la face inférieure de l'épaulement 48 de la bague brochée 13. Le premier chemin de came 56 présente au moins un premier et un deuxième niveaux. Le premier chemin de came 56 comprend autant de successions de premier et deuxième niveaux que la bague de blocage 8 comprend de plots 7. Ceux-ci sont répartis angulairement de manière à tous coopérer de manière coordonnée soit avec le premier niveau soit avec le deuxième niveau du chemin de came. On entend par niveau, des surfaces situées à des distances différentes de la boite lorsque le dispositif de commande est monté. Le passage entre les niveaux se fait de préférence progressivement. Les plots 7 sont en appui libre sur le premier chemin de came 56.The
Ainsi, en entraînant la bague de blocage 8 en rotation, les plots 7 glissent sur le premier chemin de came 56 et pressent ainsi sur la bague brochée 13. Cette dernière se déplace alors en translation, guidée par la coopération des structures de forme mâle 42 et femelle 44. Ceci a pour avantage d'éviter de mettre en rotation la couronne. Les billes 5 jouent le rôle d'organe de friction et se trouvent ainsi pressées dans leur logement et particulièrement contre la coiffe 2 et ses compartiments 39. Cette pression créé une forte friction sur la coiffe et, indirectement, sur la couronne 1, qui se trouve immobilisée. On pourra relever que, selon le mode de réalisation préféré et grâce à la forme oblongue des compartiments 39, la couronne 1 peut présenter un léger jeu dans le sens d'une translation en pression. C'est-à-dire que, en position verrouillée, le centre des billes est situé au point 66, autorisant un léger jeu jusqu'au point 64. En revanche, la couronne est immobilisée en traction. La couronne est également immobilisée en rotation. On définit ainsi un premier système de blocage en rotation et en traction de la tige de commande. On notera que, en adaptant la forme des compartiments 39, la couronne 1 pourrait être complètement bloquée dans les deux sens de translation, c'est-à-dire en pression et en traction.Thus, by driving the
En outre, la bague de blocage 8 peut comprendre un deuxième chemin de came 58 sur sa face inférieure, c'est-à-dire sur sa face située, lorsque le dispositif de commande est monté, du côté de la boîte de montre. Tout comme pour le premier chemin de came 56, ce deuxième chemin de came 58 présente au moins un premier et un deuxième niveaux, dont l'utilité apparaîtra par la suite. On entend également par niveau, des surfaces situées à des distances différentes de la boite lorsque le dispositif de commande est monté. Le passage entre les niveaux se fait de préférence progressivement, comme le montre la
Dans une variante préférée, le dispositif de commande selon l'invention peut encore comporter au moins une première bascule 30, destinée à être montée pivotante dans la boîte de montre. Cette bascule comporte une première extrémité 30a maintenue appuyée contre le deuxième chemin de came 58 et une deuxième extrémité 30b susceptible d'être au contact d'un poussoir 25 situé au voisinage de la tige de commande, pour bloquer la translation de ce dernier. Le poussoir 25 ne faisant pas directement partie de l'invention, il ne sera pas décrit en détails. La bascule 30 est maintenue au contact du deuxième chemin de came 58 par un doigt mobile 28, soumis à l'action d'un ressort 27 et monté dans la carrure 40 de la boite de montre. La forme de la première extrémité 30a est définie de manière à favoriser sa coopération et son glissement sur le deuxième chemin de came 58. Les premier et deuxième niveaux de ce dernier définissent une première et une deuxième position de la bascule 30.In a preferred variant, the control device according to the invention may also comprise at least one
Dans cette variante préférée, la deuxième extrémité 30b de la bascule 30 peut présenter une surface plane 30c se terminant par une zone d'appui 30d. Lorsque la bascule 30 est dans sa première position, elle laisse libre le poussoir 25. Comme on peut le voir sur la
La bague de blocage 8 est montée libre en rotation sur le tube 9. Sa rotation se fait sans vissage, ni déplacement axial d'elle-même. Pour améliorer le fonctionnement du dispositif de commande et permettre à l'utilisateur de déterminer si le système de blocage est en position bloquée ou libre, la position de la bague de blocage 8 est indexée. En outre et de préférence, ses mouvements de rotation sont limités entre deux positions extrêmes. Comme on peut le voir sur la
Dans un mode de réalisation préféré, le dispositif de commande selon l'invention est agencé pour bloquer simultanément les déplacements de la tige de commande et d'un poussoir 25, de préférence de deux poussoirs situés de part et d'autre de la tige de commande. Dans ce dernier cas, on a deux bascules disposées symétriquement par rapport à la tige de commande, identiques à ce qui a été décrit ci-dessus.In a preferred embodiment, the control device according to the invention is arranged to simultaneously block the movements of the control rod and a
Le deuxième chemin de came 58 comprend alors deux successions d'un premier et deuxième niveaux, diamétralement opposés deux à deux (
Les positions des plots 7 en saillie et du premier chemin de came 56, d'une part, et la position du deuxième chemin de came 58, d'autre part sont agencées de manière à ce que la tige de commande et les deux poussoirs soient bloqués simultanément, de préférence lorsque la bague de blocage 8 occupe l'une de ses positions extrêmes. Ainsi, on peut considérer que le deuxième chemin de came 58 est un élément mobile en fonction de la position occupée par le premier système de blocage. A l'inverse, lorsque la bague de blocage 8 est dans l'autre de ses positions extrêmes, la tige de commande et les deux poussoirs 25 sont libres d'être actionnés.The positions of the
Ainsi, lorsque la bague de blocage 8 est dans sa première position extrême, correspondant à une position libre du dispositif de commande, les plots 7 ne poussent pas la bague brochée 13 en direction de la couronne et les billes 5 ne sont pas pressées dans leur logement. La tige de commande est libre en rotation et en traction. Les bascules 30 sont appuyées sur le premier niveau du deuxième chemin de came 58 et sont dans leur position libre. Les poussoirs 25 peuvent être actionnés en translation.Thus, when the
L'utilisateur amène la bague de blocage 8 dans sa deuxième position extrême, par exemple par une rotation d'environ 90°, déterminée par la rainure de guidage, cette position correspondant à une position bloquée du dispositif de commande. Les plots 7 poussent alors la bague brochée 13 en direction de la couronne, la bague brochée 13 se déplaçant en translation grâce aux structures de forme 42 et 44. Les billes 5 se trouvent alors pressées dans leur logement, bloquant la tige de commande en rotation et en traction. Simultanément, les bascules 30 sont appuyées sur le deuxième niveau du deuxième chemin de came 58 et sont dans leur position bloquée. Les poussoirs ne peuvent plus être actionnés en translation.The user brings the
Par une rotation de 90° de la bague de blocage 8 dans le sens inverse, on ramène le dispositif de commande à sa position libre.By a 90 ° rotation of the
On pourra encore remarquer sur la
Ainsi est proposé un dispositif de commande permettant, par une simple rotation d'une bague de blocage, de verrouiller les déplacements d'une tige de commande (en pratique, d'une tige de remontoir). Dans une variante avantageuse, le dispositif de commande permet, simultanément au verrouillage de la tige de commande, de verrouiller également les déplacements d'un ou de plusieurs poussoirs.Thus is proposed a control device allowing, by a simple rotation of a locking ring, to lock the movements of a control rod (in practice, a winding stem). In an advantageous variant, the control device makes it possible, simultaneously with the locking of the control rod, to also lock the movements of one or more pushers.
Le mode de réalisation ci-dessus n'a été donné qu'à titre d'exemple non limitatif et seules les revendications déterminent la portée de l'invention.The above embodiment has been given by way of non-limiting example and only the claims determine the scope of the invention.
