Description

La présente invention concerne un dispositif de commande d'une pièce d'horlogerie comprenant un poussoir présentant une tête fixée à un axe monté coulissant dans un tube apte à traverser la carrure de la pièce d'horlogerie et un ressort tendant à pousser la tête vers l'extérieur, en position inactive.The present invention relates to a control device of a timepiece comprising a pusher having a head fixed to a shaft slidably mounted in a tube adapted to pass through the middle part of the timepiece and a spring tending to push the head towards outside, inactive position.

Plus particulièrement, l'invention a pour objet un tel poussoir pouvant être verrouillé dans sa position inactive. Ceci est particulièrement important pour les pièces d'horlogerie comportant des poussoirs de grande dimension qui peuvent saillir de la boîte de la pièce d'horlogerie sur plusieurs millimètres. En effet, pour ces pièces d'horlogerie à poussoirs particulièrement saillants, il arrive que ce ou ces poussoirs soient activés ou actionnés involontairement par des mouvement du porteur de la pièce d'horlogerie par exemple en se cognant contre un meuble.More particularly, the subject of the invention is such a pusher that can be locked in its inactive position. This is particularly important for timepieces with large pushers that can protrude from the timepiece of the watch over several millimeters. Indeed, for these timepieces particularly prominent timepieces, it happens that this or these buttons are activated or actuated involuntarily by movement of the wearer of the timepiece for example by bumping against a piece of furniture.

Un but de la présente invention est d'éviter des actionnements intempestifs des poussoirs d'une pièce d'horlogerie en verrouillant ces poussoirs dans leurs positions inactives afin que l'usager doive procéder à une manoeuvre de déverrouillage du poussoir avant de pouvoir l'actionner pour activer une fonction de la pièce d'horlogerie.An object of the present invention is to avoid inadvertent actuation of the pushers of a timepiece by locking these pushers in their inactive positions so that the user must proceed to an unlocking maneuver before the push button can operate to activate a function of the timepiece.

On connaît un poussoir verrouillable du document CH 350249 mais le verrouillage décrit dans ce document permet de maintenir le poussoir en position activée ce qui est contraire au but recherché par la présente invention.There is a lockable document pusher CH 350249 but the lock described in this document keeps the pusher in the activated position which is contrary to the purpose of the present invention.

Les documents WO2007/113723A2 et CH 697706B1 décrivent des dispositifs de verrouillage d'un poussoir en position inactive comportant une cage ou bague de blocage se vissant sur la tête du poussoir dont l'extrémité de la jupe dépasse la partie du poussoir proche de la boîte de montre en position de blocage et vient buter contre la boîte de montre interdisant ainsi d'actionner le poussoir.The documents WO2007 / 113723A2 and CH 697706B1 describe locking devices of a pusher in an inactive position comprising a cage or locking ring screwing onto the head of the pusher whose end of the skirt protrudes beyond the portion of the pusher close to the watch case in the locking position and comes abut against the watch case thus prohibiting the actuation of the pusher.

Cette cage ou bague de blocage complique et renchérit le poussoir tout en le rendant plus volumineux. De plus, pour que le dévissage de cette cage ou bague de blocage soit facile, il faut que le poussoir ne puisse pas tourner sur lui-même ce qui complique encore sa réalisation.This cage or locking ring complicates and increases the pusher while making it more bulky. In addition, for the unscrewing of this cage or locking ring is easy, it is necessary that the pusher can not turn on itself which further complicates its realization.

Le document EP 1853977B1 décrit un poussoir verrouillable comportant, entre le tube traversant la carrure d'une boîte de montre et la tête du poussoir, une bague de compression vissée sur le tube et permettant, une fois vissée, de comprimer un joint de compression pour augmenter l'étanchéité de la boîte. Dans cette position vissée, cette bague permet également de verrouiller la tête du poussoir en position inactive. Cette bague de compression constitue également une pièce supplémentaire.The document EP 1853977B1 discloses a lockable pusher having, between the tube passing through the middle of a watch case and the pusher head, a compression ring screwed onto the tube and allowing, once screwed, to compress a compression seal to increase the seal of the box. In this screwed position, this ring also locks the pusher head in the inactive position. This compression ring is also an additional piece.

Enfin, le document CH 675809A3 décrit un poussoir comportant une couronne fixée à la boîte de montre autour du tube du poussoir et comportant deux fentes de longueurs différentes débouchant sur la face libre de la couronne. Ces fentes coopèrent avec une ailette que comporte la tête du poussoir. Suivant la position angulaire de la tête du poussoir, son ailette coulisse dans l'une ou l'autre de ces fentes, l'une d'elles limitant la course axiale du poussoir pour qu'il ne puisse pas activer la fonction qu'il commande. Ici également une pièce supplémentaire est nécessaire et de plus, pour passer d'une position verrouillée à une position déverrouillée du poussoir, il faut tirer la tête vers l'extérieur de la montre puis la tourner pour faire passer l'ailette de la tête d'une fente à l'autre de la couronne.Finally, the document CH 675809A3 discloses a pusher having a ring fixed to the watch case around the pusher tube and having two slots of different lengths opening on the free face of the ring. These slots cooperate with a fin that includes the head of the pusher. According to the angular position of the pusher head, its fin slides in one or other of these slots, one of them limiting the axial stroke of the pusher so that it can not activate the function it ordered. Here, too, an additional piece is necessary and in addition, to move from a locked position to an unlocked position of the pusher, it is necessary to pull the head towards the outside of the watch and then turn it to pass the fin of the head of the watch. one slot to the other of the crown.

La présente invention a pour but la réalisation d'un poussoir verrouillable dans sa position inactive présentant un faible nombre de pièces et conçu pour que la manoeuvre de verrouillage ou de déverrouillage soit facile à exécuter.The present invention aims to achieve a lockable push in its inactive position with a small number of parts and designed so that the locking or unlocking maneuver is easy to perform.

L'invention a pour objet un poussoir verrouillable comportant un tube ainsi qu'une vis traversant ce tube et guidée par ce tube vissée dans une tête et un ressort disposé entre le tube et la tête tendant à les éloigner l'un de l'autre, caractérisé par le fait que la tête comporte au moins un organe de guidage coopérant avec une rainure longitudinale du tube et avec une rainure de verrouillage du tube formant un angle α avec l'axe de la rainure longitudinale.The invention relates to a lockable pusher comprising a tube and a screw passing through the tube and guided by this tube screwed into a head and a spring disposed between the tube and the head tending to move them away from each other , characterized in that the head comprises at least one guide member cooperating with a longitudinal groove of the tube and with a locking groove of the tube forming an angle α with the axis of the longitudinal groove.

La figure 1 illustre schématiquement une montre bracelet équipée d'un mécanisme auxiliaire tel qu'un second fuseau, un quantième, un chronographe, etc. pouvant être actionné ou corrigé à l'aide d'un poussoir depuis l'extérieur de la boîte de montre. Bien que décrit en référence à une boîte de montre bracelet, le poussoir peut équiper n'importe quelle paroi à travers laquelle un mécanisme doit pouvoir être actionné.The figure 1 schematically illustrates a wristwatch equipped with an auxiliary mechanism such as a second spindle, a calendar, a chronograph, etc. can be operated or corrected with a pusher from outside the watch case. Although described with reference to a wristwatch case, the pusher can equip any wall through which a mechanism must be operable.

La boîte de montre bracelet comporte une carrure 1 et renferme un mouvement d'horlogerie comportant un mécanisme auxiliaire commandé par une bascule 2 dont une extrémité 3 est agencée pour être actionnée par un poussoir 4 depuis l'extérieur de la carrure 1.The wristwatch watch case comprises a caseband 1 and encloses a clockwork movement comprising an auxiliary mechanism controlled by a rocker 2 whose one end 3 is arranged to be actuated by a pushbutton 4 from outside the middle part 1.

Le poussoir comporte un tube usiné 5 comportant une collerette 5a et un filetage extérieur 5b formant l'extrémité intérieure du tube usiné 5. Cette extrémité du tube usiné 5 comporte un évidement 5c coaxial au tube usiné 5. La partie extérieure du tube usiné 5, située de l'autre côté de sa collerette 5a comporte un logement 5d de diamètre supérieur ou égal au diamètre de l'évidement 5c débouchant sur la face extérieure du tube usiné 5 et relié par un alésage 5e à cet évidement 5c.The pusher comprises a machined tube 5 comprising a flange 5a and an external thread 5b forming the inner end of the machined tube 5. This end of the machined tube 5 has a recess 5c coaxial with the machined tube 5. The outer part of the machined tube 5, located on the other side of its flange 5a comprises a housing 5d of diameter greater than or equal to the diameter of the recess 5c opening on the outer face of the machined tube 5 and connected by a bore 5e to this recess 5c.

La partie extérieure du tube usiné 5 comporte trois rainures longitudinales 5f pratiquées dans sa surface cylindrique extérieure et débouchant sur sa face supérieure. La surface cylindrique extérieure de la partie extérieure du tube usiné 5 comporte encore trois rainures de verrouillage 5g inclinées d'un angle α par rapport à l'axe des rainures longitudinales 5f débouchant chacune dans une des rainures longitudinales 5f. Ces rainures de verrouillage 5g sont inclinées en direction de la collerette 5a et comportent à leur extrémité éloignée de la rainure longitudinale 5f dans laquelle elles débouchent, une extension axiale 5h formant un cran d'arrêt. La largeur et la profondeur des rainures longitudinales 5f et des rainures de verrouillage 5g sont égales.The outer portion of the machined tube 5 has three longitudinal grooves 5f formed in its outer cylindrical surface and opening on its upper face. The outer cylindrical surface of the outer portion of the machined tube 5 further comprises three locking grooves 5g inclined at an angle α with respect to the axis of the longitudinal grooves 5f each opening into one of the longitudinal grooves 5f. These locking grooves 5g are inclined in the direction of the flange 5a and have at their end remote from the longitudinal groove 5f in which they open, an axial extension 5h forming a detent. The width and the depth of the longitudinal grooves 5f and the locking grooves 5g are equal.

Les rainures longitudinales 5f sont uniformément réparties autour de l'extrémité supérieure du tube usiné et sont donc décalées angulairement de 120°.The longitudinal grooves 5f are uniformly distributed around the upper end of the machined tube and are therefore angularly offset by 120 °.

Le poussoir comporte encore une tête 6 munie d'une jupe cylindrique 6a comportant trois perçages 6b décalés de 120° les uns par rapport aux autres.The pusher further comprises a head 6 provided with a cylindrical skirt 6a having three bores 6b shifted by 120 ° relative to each other.

Des goupilles 6c sont logées dans ces perçages 6b et maintenues en place par une bague 6d sertie sur la jupe 6a de la tête 6. La bague 6d comporte une rainure circulaire 6e débouchant sur sa périphérie à proximité de son extrémité libre.Pins 6c are housed in these holes 6b and held in place by a ring 6d set on the skirt 6a of the head 6. The ring 6d has a circular groove 6 opening on its periphery near its free end.

La tête 6 du poussoir est montée coulissante sur le tube usiné 5, l'extrémité des goupilles 6c coulissant dans les rainures longitudinales 5f du tube usiné 5.The head 6 of the pusher is slidably mounted on the machined tube 5, the end of the pins 6c sliding in the longitudinal grooves 5f of the machined tube 5.

Une vis 7 est vissée dans la tête 6 et s'étend au travers du tube usiné 5, guidée par son alésage 5e et comporte une portion terminale 7a de plus gros diamètre terminée par un six pans 7b.A screw 7 is screwed into the head 6 and extends through the machined tube 5, guided by its bore 5e and has a terminal portion 7a of larger diameter terminated by a hex 7b.

Un ressort 8 est logé autour de la vis 7 dans la tête 6 du poussoir et dans le logement 5d du tube usiné 5 prenant appuis contre le fond de ce logement 5d par deux joints et une rondelle. Ce ressort 8 tend à éloigner la tête 6 de la partie extérieure du tube usiné 5 jusque dans une position où la partie de gros diamètre 7a de la vis 7 vient en butée contre le fond de l'évidement 5c du tube usiné 5.A spring 8 is housed around the screw 7 in the head 6 of the pusher and in the housing 5d of the machined tube 5 bearing against the bottom of this housing 5d by two seals and a washer. This spring 8 tends to move the head 6 away from the outside of the machined tube 5 to a position where the large diameter portion 7a of the screw 7 abuts against the bottom of the recess 5c of the machined tube 5.

Le poussoir 4 ainsi constitué est vissé dans un taraudage pratiqué dans la carrure 1 de la boîte de montre correspondant au filetage 5b du tube usiné 5, la collerette du tube usiné venant butter contre la face externe de la carrure 1. Ainsi la tête 6 du poussoir est située à l'extérieur de la boîte de montre tandis que le six pans 7b de la vis 7 du poussoir est situé, en position verrouillée du poussoir (figures 3,4) à proximité immédiate, soit environ 0,2mm, de l'extrémité 3 de la bascule 2 de commande d'un mécanisme logé dans la boîte de montre.The pusher 4 thus formed is screwed into a tapping made in the middle part 1 of the watch case corresponding to the thread 5b of the machined tube 5, the collar of the machined tube coming to bear against the outer face of the middle part 1. Thus the head 6 of the pusher is located outside the watch case while the hexagon 7b of the screw 7 of the pusher is located in the locked position of the pusher ( figures 3,4 ) in the immediate vicinity, about 0.2mm, of the end 3 of the rocker 2 for controlling a mechanism housed in the watch case.

Dans la position verrouillée (figures 3,4) du poussoir, les goupilles 6c de la tête 6 du poussoir sont logées dans le cran d'arrêt 5h des rainures de verrouillage 5g du tube usiné 5 et maintenues dans cette position par le ressort 8. Comme indiqué précédemment, dans cette position verrouillée, le six pans 7b de la vis 7 est situé à une faible distance de l'extrémité 3 de la bascule de commande 2, distance de l'ordre de quelques dixièmes, 0,1 à 0,3 mm par exemple.In the locked position ( figures 3,4 ) of the pusher, the pins 6c of the head 6 of the pusher are housed in the detent 5h locking grooves 5g of the machined tube 5 and held in this position by the spring 8. As indicated above, in this locked position, the hex 7b of the screw 7 is located at a short distance from the end 3 of the control lever 2, distance of the order of a few tenths, 0.1 to 0.3 mm for example.

Dans cette position, si l'usager provoque une poussée axiale, volontaire ou non, sur la tête 6 du poussoir, cette tête 6 et la vis 7 vont se déplacer en direction de l'intérieur de la boîte de montre soit de l'extrémité 3 de la bascule de commande 2 sur une distance correspondant à la longueur de l'extension axiale 5h qui est de préférence inférieure à la distance séparant le six pans 7b de l'extrémité 3 de la bascule 2 lorsque le poussoir est en position verrouillée. De cette façon, la course de la tête 6 et de la vis 7 est stoppée avant que la vis n'entre en contact avec l'extrémité 3 de la bascule de commande.In this position, if the user causes an axial thrust, voluntary or not, on the head 6 of the pusher, this head 6 and the screw 7 will move towards the inside of the watch case is the end 3 of the control lever 2 over a distance corresponding to the length of the axial extension 5h which is preferably less than the distance between the hex 7b of the end 3 of the rocker 2 when the pusher is in the locked position. In this way, the stroke of the head 6 and the screw 7 is stopped before the screw comes into contact with the end 3 of the control lever.

Ainsi, tout déplacement axial de la tête 6 qui n'est pas associé volontairement à une rotation de cette tête 6 ne peut pas provoquer l'actionnement du mécanisme devant être commandé par le poussoir. Cela évite toute commande intempestive de ce mécanisme.Thus, any axial displacement of the head 6 which is not deliberately associated with a rotation of the head 6 can not cause the actuation of the mechanism to be controlled by the pusher. This avoids any untimely control of this mechanism.

Pour actionner le mécanisme devant être commandé par le poussoir, l'usager doit à partir de la position verrouillée du poussoir (figures 3,4) déplacer axialement la tête 6 jusqu'à une position intermédiaire où les goupilles 6c peuvent s'engager, par une rotation de la tête 6 (figures 6,7) dans les rainures de verrouillage 5g. Puis, l'usager tourne la tête 6 de manière à déplacer les goupilles 6c dans les rainures de verrouillage 5g jusqu'à ce que ces goupilles 6c soient engagées dans les rainures longitudinales 5f correspondantes (figures 8,9).To actuate the mechanism to be controlled by the pusher, the user must from the locked position of the pusher ( figures 3,4 ) axially moving the head 6 to an intermediate position where the pins 6c can engage, by a rotation of the head 6 ( figures 6.7 ) in the locking grooves 5g. Then, the user turns the head 6 so as to move the pins 6c in the locking grooves 5g until these pins 6c are engaged in the corresponding longitudinal grooves 5f ( Figures 8.9 ).

A ce moment, l'usager peut déplacer axialement la tête 6 en direction du tube usiné 5 les goupilles 6c coulissant dans les rainures longitudinales 5g jusqu'à ce que le six pans 7b entre en contact avec l'extrémité 3 de la bascule de commande 2 (figures 10,11). Un déplacement supplémentaire de la tête 6 en direction du tube usiné 5 provoquera alors le déplacement de l'extrémité 3 de la bascule de commande et l'actionnement du mécanisme correspondant (figures 12, 13).At this moment, the user can axially move the head 6 towards the machined tube 5 the pins 6c sliding in the longitudinal grooves 5g until the hex 7b comes into contact with the end 3 of the control lever 2 ( Figures 10.11 ). An additional displacement of the head 6 in the direction of the machined tube 5 will then cause the displacement of the end 3 of the control flip-flop and the actuation of the corresponding mechanism ( Figures 12, 13 ).

Puis en relâchant la pression exercée sur la tête 6, celle-ci revient en position déverrouillée du poussoir (figures 8,9). Si l'usager provoque alors une rotation inverse de la tête 6, les goupilles 6c s'engagent dans les rainures de verrouillage 5g correspondantes puis en fin de rotation dans les crans d'arrêt 5h et le poussoir se retrouve en position verrouillée (figures 3,4).Then releasing the pressure exerted on the head 6, it returns to the unlocked position of the pusher ( Figures 8.9 ). If the user then causes an opposite rotation of the head 6, the pins 6c engage in the corresponding locking grooves 5g and then at the end of rotation in the detents 5h and the pusher is in the locked position ( figures 3,4 ).

Ainsi, avec un tel poussoir verrouillable, l'usager doit avant de pousser sur la tête du poussoir effectuer une rotation de celle-ci de 60° pour qu'il soit alors possible de déplacer axialement le poussoir dans sa course active de commande d'un mécanisme. On empêche ainsi toute commande intempestive de ce mécanisme, le poussoir ne pouvant pas être actif lorsqu'il est dans sa position verrouillée, évitant ainsi tout actionnement intempestif du poussoir.Thus, with such a lockable pushbutton, the user must before pushing on the head of the pusher to rotate it by 60 ° so that it is then possible to move the pusher axially in its active control stroke. a mechanism. This prevents any unwanted control of this mechanism, the pusher can not be active when in its locked position, thus avoiding inadvertent actuation of the pusher.

Dans des variantes d'exécution du poussoir verrouillable, les goupilles peuvent être remplacées par des billes ou autre élément de guidage apte à coopérer avec les rainures longitudinales et les rainures de verrouillage du tube usiné 5. De même, le nombre de goupilles ou de ces organes de guidage et des rainures correspondantes pourrait être différent de trois, par exemple deux ou cinq, ou au moins un.In alternative embodiments of the lockable pusher, the pins may be replaced by balls or other guide element adapted to cooperate with the longitudinal grooves and the locking grooves of the machined tube 5. Similarly, the number of pins or these Guide members and corresponding grooves could be different from three, for example two or five, or at least one.

Dans l'exécution illustrée, la carrure 1 est munie d'un cache cylindrique 9 dans lequel coulisse la bague 6d lors des déplacements axiaux de la tête 6. La hauteur de ce cache 9 est telle que lorsque le poussoir est en position verrouillée (figures 3,4), la rainure circulaire 6e de la bague 6d est invisible, tandis qu'elle est visible lorsque le poussoir est en position déverrouillée (figures 10,11). Ceci permet à l'usager de voir immédiatement dans quelle position se trouve le poussoir. Pour le rendre plus visible, la rainure circulaire peut être colorée. Dans une variante, la bague 6d peut ne pas comporter de rainure circulaire mais simplement un repère ou une ligne colorée.In the embodiment illustrated, the middle part 1 is provided with a cylindrical cover 9 in which the ring 6d slides during axial displacements of the head 6. The height of this cover 9 is such that when the pusher is in the locked position ( figures 3,4 ), the circular groove 6e of the ring 6d is invisible, while it is visible when the pusher is in the unlocked position ( Figures 10.11 ). This allows the user to see immediately in which position is the pusher. To make it more visible, the circular groove can be colored. In a variant, the ring 6d may not have a circular groove but simply a marker or a colored line.

Comme on le voit, le poussoir verrouillable comporte un dispositif de verrouillage du type à bayonnette constitué des rainures longitudinales 5f, des rainures de verrouillage 5g et des goupilles 6c qui imposent à l'utilisateur de communiquer à la tête 6 du poussoir un mouvement combiné de rotation et le déplacement axial pour passer de sa position verrouillée à sa position active de commande de manière à éviter tout actionnement intempestif du mécanisme commandé par le poussoir.As can be seen, the lockable pusher comprises a bayonet type locking device consisting of longitudinal grooves 5f, locking grooves 5g and pins 6c which force the user to communicate to the head 6 of the pusher a combined movement of rotation and axial displacement to move from its locked position to its active control position so as to avoid inadvertent actuation of the mechanism controlled by the pusher.

Il va de soi qu'un tel poussoir verrouillable peut équiper autre chose qu'une boîte de montre, il peut être vissé sur toute sorte de boîte ou de paroi servant de support au poussoir.It goes without saying that such a lockable pusher can equip something other than a watch case, it can be screwed on any kind of box or wall serving as support for the pusher.

Néanmoins, ce mouvement combiné de la tête du poussoir s'obtient en pratique par une rotation de la tête, l'utilisateur n'étant pas obligé de volontairement déplacer celle-ci axialement, le dispositif étant conçu pour qu'un couple imposé à la tête du poussoir provoque automatiquement le déplacement axial de celle-ci nécessaire à son verrouillage ou son déverrouillage.Nevertheless, this combined movement of the pusher head is obtained in practice by a rotation of the head, the user is not obliged to deliberately move it axially, the device being designed so that a torque imposed on the pusher head automatically causes the axial displacement thereof necessary for locking or unlocking.

Ceci est obtenu par la position des goupilles par rapport aux rainures de verrouillage tant en position verrouillée que déverrouillée. En fait dans ces positions, les goupilles sont soit dans les crans d'arrêt soit dans les rainures longitudinales mais positionnées de telle sorte qu'elles dépassent déjà l'entrée dans les rainures de verrouillage de sorte qu'une rotation de la tête provoque automatiquement la course axiale nécessaire au passage des goupilles dans les rainures de verrouillage.This is achieved by the position of the pins relative to the locking grooves in both locked and unlocked positions. In fact in these positions, the pins are either in the detents or in the longitudinal grooves but positioned so that they already protrude beyond the entrance into the locking grooves so that a rotation of the head automatically causes the axial stroke necessary for the pins to pass through the locking grooves.

Dans des variantes, la construction de la tête du poussoir pourrait être différente en pratique, la bague 6d peut être supprimée et la goupille 6c pouvant être solidarisée différemment sur la jupe 6a de la tête 6 ou même venue d'une pièce de fabrication avec celle-ci.In variants, the construction of the pusher head could be different in practice, the ring 6d can be removed and the pin 6c can be secured differently on the skirt 6a of the head 6 or even come from a workpiece with that -this.

Le cache 9 est évidemment optionnel de même que la rainure circulaire 6e.The cover 9 is obviously optional as well as the circular groove 6e.

Le poussoir verrouillable selon l'invention est simple, ne nécessite qu'un minimum de pièces et est facile à manoeuvrer.The lockable pusher according to the invention is simple, requires only a minimum of parts and is easy to maneuver.
