Description

La présente invention se rapporte aux dispositifs de commande à poussoir pour montres munies d'une couronne destinée à la mise à l'heure et, lorsqu'elles sont comportent une source d'énergie mécanique, au remontage du barillet. De manière plus précise, elle concerne les montres comportant un poussoir coaxial à la couronne. De telles montres sont, par exemple, décrites et représentées dans l'ouvrage intitulé "Le Chronographe", B. Humbert, Scriptar SA, Lausanne 1955. II s'agit généralement d'un chronographe ou d'un compteur.The present invention relates to push-button controllers for watches equipped with a crown intended for setting the time and, when they include a source of mechanical energy, when reassembled barrel. More specifically, it concerns watches with a pusher coaxial to the crown. Such watches are, for example, described and represented in the book entitled "The Chronograph", B. Humbert, Scriptar SA, Lausanne 1955. This is usually a chronograph or a counter.

Dans le cadre de le présente description, les positions des différents composants disposés à la périphérie de la montre sont définies en référence à la position qu'occuperait une aiguille des heures à un temps donné.In the context of this description, the positions of the different components arranged at the periphery of the watch are defined with reference to the position that would occupy an hour hand at a given time.

Le fait de placer le poussoir concentriquement à la couronne, comme proposé dans le document CH 226715, simplifie la structure de la boíte et peut conférer à la montre une esthétique particulière. Dans la plupart des cas, la couronne se trouve à 3 heures. Cette position est ergonomiquement favorable pour assurer le remontage et la mise à l'heure de la montre. Par contre, une pression sur un poussoir occupant cette position nécessite des mouvements peu naturels. Le but de la présente invention est de pallier cet inconvénient.Placing the pusher concentrically to the crown as proposed in document CH 226715, simplifies the structure of the box and can give the watch a particular aesthetic. In most cases, the crown is at 3 o'clock. This position is ergonomically favorable to reassemble and set the time of the watch. On the other hand, a pressing on a pushbutton occupying this position requires movements not natural. The object of the present invention is to overcome this drawback.

A cet effet, le dispositif selon l'invention est caractérisé en ce qu'il comporte, en outre, un levier monté pivotant sur ladite boíte par l'une de ses extrémités, mobile dans un plan sensiblement parallèle au plan de la montre, comportant, dans sa partie médiane, un point de contact destiné à coopérer avec le poussoir et, à son autre extrémité, une portion de commande, de forme concave.For this purpose, the device according to the invention is characterized in that it comprises, in addition, a lever pivoted on said box by one of its ends, mobile in a plane substantially parallel to the plane of the watch, comprising, in its middle part, a point of contact intended to cooperate with the push button and, at its other end, a control portion, of shape concave.

La combinaison d'un levier avec un poussoir est aussi connue, notamment par les documents US 3759033, EP 0443087 ou CH 13865/75, qui décrive des chronographes ou des compteurs dans lesquels les poussoirs sont intégrés dans la boíte. The combination of a lever with a pusher is also known, in particular by US 3759033, EP 0443087 or CH 13865/75, which describes chronographs or counters in which the pushers are integrated in the box.

Pour que le dispositif remplisse pleinement sa fonction, il est nécessaire que le levier soit fixé solidement à la boíte et disposé de manière à éviter toute action intempestive. C'est pourquoi, dans un premier mode de réalisation, le poussoir comporte un bouton partiellement engagé dans la couronne et formant une protubérance. La boíte comprend, en outre un étrier chevauchant la couronne et le poussoir. Cet étrier est fixé par ses deux extrémités à la carrure. Le levier est monté pivotant sur l'étrier, et s'étend entre la partie chevauchante et le bouton, puis au-delà de l'étrier pour former la portion de commande.In order for the device to perform its full function, it is necessary that the lever is firmly fixed to the box and arranged so as to avoid any untimely action. This is why, in a first embodiment, the pusher has a button partially engaged in the crown and forming a protuberance. The box includes, in addition a stirrup overlapping the crown and the pusher. This stirrup is fixed by its two ends to the build. The lever is pivotally mounted on the caliper, and extends between the part overlap and the button and then beyond the stirrup to form the portion of ordered.

Avantageusement, la boíte comporte un tube dans lequel sont disposés le poussoir et la tige, alors que l'étrier est muni d'une bride fixée à ses deux extrémités et enserrant ce tube.Advantageously, the box comprises a tube in which are arranged the push rod and the rod, while the stirrup has a flange attached to both ends and enclosing this tube.

Selon un second mode de réalisation, permettant également de fixer solidement le levier à la boíte et éviter toute manoeuvre intempestive, le poussoir comporte une portion annulaire interposée entre la couronne et la carrure et le levier est intercalé entre cette portion annulaire et la couronne.According to a second embodiment, which also makes it possible to fix firmly the lever to the box and avoid any untimely maneuver, the pusher comprises an annular portion interposed between the crown and the middle and the lever is interposed between this annular portion and the crown.

Afin d'assurer une fixation solide et fiable, la carrure est munie d'un plot sur lequel le levier est monté pivotant.In order to ensure a solid and reliable fixation, the middle part is provided with a stud on which lever is pivotally mounted.

De telles solutions sont particulièrement avantageuses lorsque la couronne se trouve à 9 heures et la portion de commande à 8 heures environ, car les organes protubérants se trouvent dans une partie bien protégée, puisque placée du côté du coude. De la sorte, le risque d'accrochage est sensiblement réduit.Such solutions are particularly advantageous when the crown is at 9 o'clock and the control portion at about 8 o'clock, because protruding organs are in a well protected part, since placed on the side of the elbow. In this way, the risk of snagging is substantially reduced.

D'autres avantages et caractéristiques de l'invention ressortiront de la description qui va suivre, faite en regard du dessin annexé, dans lequel:

  • Les figures 1 et 2 montrent un dispositif de commande selon un premier mode de réalisation de l'invention, vu respectivement de dessus et en coupe selon la ligne II-II de la figure 1, et
  • Les figures 3 et 4 représentent un dispositif selon un second mode de réalisation, vu de dessus en plan et en coupe.
Other advantages and features of the invention will emerge from the description which follows, given with reference to the appended drawing, in which:
  • FIGS. 1 and 2 show a control device according to a first embodiment of the invention, viewed respectively from above and in section along line II - II of FIG. 1, and
  • Figures 3 and 4 show a device according to a second embodiment, seen from above in plan and in section.

Les figures 1 et 2 montrent une partie de montre comportant une boíte 10 comportant notamment une carrure 12 et un tube 14 chassé dans un trou de la carrure. Un mouvement de montre, non représenté au dessin, est logé dans la boíte 10. II est de type chronographe, commandé par une tige 16 et par un poussoir 18.FIGS. 1 and 2 show a watch part comprising a box 10 including a middle part 12 and a tube 14 driven into a hole of the build. A watch movement, not shown in the drawing, is housed in the box 10. It is chronograph type, controlled by a rod 16 and by a push 18.

Le tube 14 est formé d'une première portion 14a, engagée dans la carrure 12, et d'une seconde 14b disposée du côté extérieur à cette carrure. La seconde portion 14b comporte une collerette 14c annulaire et une gorge 14d à orientation parallèle à l'axe du tube.The tube 14 is formed of a first portion 14a, engaged in the middle part 12, and a second 14b disposed on the outside of this middle. The second portion 14b has an annular flange 14c and a groove 14d to parallel orientation to the axis of the tube.

La tige 16 porte, à son extrémité extérieure, une couronne 20 destinée à la mise à l'heure et, s'il s'agit d'une montre mécanique, au remontage de la source d'énergie. La couronne 20 comprend une première partie 20a, extérieure et de forme annulaire, une deuxième partie 20b, formant un noyau solidaire de la tige 16 et une troisième partie, intermédiaire, constituée de trois rayons 20c orientés radialement et reliant le noyau 20b à la partie 20a.The rod 16 carries, at its outer end, a ring 20 intended for the time and, in the case of a mechanical watch, when reassembling the energy source. The ring 20 comprises a first part 20a, outer and ring-shaped, a second portion 20b forming a core secured to the rod 16 and a third part, intermediate, consisting of three radially oriented radii 20c and connecting the core 20b to the portion 20a.

Le poussoir 18 comporte une pièce tubulaire 22 et un bouchon 23 fixé à l'extrémité de la pièce 22 pour fermer le trou se trouvant du côté extérieur à la boíte 10. La pièce tubulaire 22 est munie, dans sa portion voisine du bouchon 23, de trois gorges 22a s'étendant sur toute sa partie disposée à l'extérieur du tube 14, dans lesquelles sont engagés les rayons 20c. On relèvera que la distance axiale du noyau 20b et des rayons 20c au bouchon 23 est de l'ordre de 1 mm environ. II est, de la sorte, possible d'assurer un déplacement suffisant du poussoir pour commander le mécanisme auquel il est associé et de la couronne lors de la fonction de mise à l'heure.The pusher 18 comprises a tubular piece 22 and a plug 23 fixed to the end of the piece 22 to close the hole on the outside of the box 10. The tubular part 22 is provided, in its adjacent portion of the cap 23, of three grooves 22a extending over its entire portion disposed outside the tube 14, in which the spokes 20c are engaged. It will be noted that the axial distance from the core 20b and 20c spokes to the plug 23 is of the order about 1 mm. It is thus possible to ensure a displacement enough pusher to control the mechanism with which it is associated and of the crown during the time setting function.

Le bouchon 23 dépasse de la couronne 20 pour former un bouton destiné à appliquer une pression pour commander une fonction de la montre.The cap 23 protrudes from the crown 20 to form a button intended for apply pressure to control a function of the watch.

Un étrier 24, formant une boucle autour de la couronne 16 et du poussoir 18, est fixé sur le tube 14 par une bride 26, rendue solidaire de l'étrier 24 par des vis 28. Plus précisément, l'étrier 24 et la bride 26 comportent une gorge annulaire identifiée par la lettre a dans laquelle la collerette 14aest engagée, ce qui bloque axialement l'étrier 24. Une creusure 26b est pratiquée dans la bride 26, parallèlement à la gorge 14d, de même largeur et de même longueur. Une clavette 30 est disposée dans le logement formé par la gorge 14d et la creusure 26b, bloquant, ainsi, l'étrier en rotation.A stirrup 24, forming a loop around the ring 16 and the pusher 18, is fixed on the tube 14 by a flange 26, made integral with the stirrup 24 by screws 28. More precisely, the stirrup 24 and the clamp 26 comprise an annular groove identified by the letter in which the collar 14aest engaged, which axially locks the bracket 24. a recess 26b is formed in the flange 26, parallel to the groove 14d of the same width and the same length. A key 30 is disposed in the housing formed by the groove 14d and the recess 26b, thereby blocking the stirrup in rotation.

L'étrier 24 porte un levier 32, monté pivotant par l'une de ses extrémités 32a au moyen d'une goupille 34 engagée dans trous du levier 32 et de l'étrier 24. Le levier 32 est mobile dans un plan sensiblement parallèle au plan de la montre, qui est définit par la surface de son cadran.The stirrup 24 carries a lever 32 pivotally mounted by one of its ends 32a by means of a pin 34 engaged in holes of the lever 32 and the stirrup 24. The lever 32 is movable in a plane substantially parallel to the plane of the watch, which is defined by the surface of its dial.

Le levier 32 comporte, dans sa partie médiane 32b, un point de contact destiné à coopérer avec le poussoir 18, en prenant appui sur le bouchon 23. L'autre extrémité 32c constitue une portion de commande, de forme concave.The lever 32 comprises, in its median part 32b, a point of contact intended to cooperate with the pusher 18, bearing on the stopper 23. The other end 32c constitutes a control portion, of concave shape.

Le dispositif de commande comporte, en outre, un ressort assurant le retour du poussoir 14 ainsi que des joints d'étanchéités pour éviter la pénétration d'eau dans le mouvement. Ces pièces ne seront pas décrites de manière plus détaillées, car ne faisant par partie de l'invention.The control device further comprises a spring ensuring the return of the pusher 14 as well as seals to prevent penetration of water in the movement. These pieces will not be described more detailed because not part of the invention.

Le dispositif tel que décrit permet s'assurer les fonctions suivantes.The device as described allows to ensure the following functions.

Lorsque le dispositif se présente dans la position représentée au dessin, l'application d'un couple sur la couronne 20 a pour effet de faire tourner la tige 16, ce qui arme la source d'énergie de la montre s'il s'agit d'une pièce mécanique. Ce mouvement de rotation fait également tourner le poussoir 18, sans conséquence.When the device is in the position shown in the drawing, the application of a torque on the ring 20 has the effect of rotating the rod 16, which forces the power source of the watch if it is a coin mechanical. This rotational movement also turns the pusher 18, without consequence.

Pour effectuer la mise à l'heure de la montre, il suffit de tirer la couronne 20 vers l'extérieur. Cela est possible, à cause du jeu compris entre les parties 20b et 20c de la couronne 20 et le bouchon 23. En tournant ensuite la couronne 20, on corrige la position des aiguilles, grâce à un mécanisme bien connu, associé au mouvement de la montre.To set the time of the watch, simply pull the crown 20 outwards. This is possible because of the game between the parties 20b and 20c of the ring 20 and the cap 23. Then turning the crown 20, the position of the needles is corrected thanks to a well known, associated with the movement of the watch.

Le poussoir 18 permet de commander une fonction complémentaire, par exemple un chronographe, une première pression provoquant le démarrage du mécanisme de chronographe, une deuxième son arrêt et une troisième la mise à zéro des aiguilles. Pour commander ces fonctions, il suffit de presser sur l'extrémité 32c du levier 32 avec un doigt. On relèvera que la forme concave de cette extrémité permet de bien positionner le doigt chargé d'appliquer la pression.The pusher 18 makes it possible to control a complementary function, for example example a chronograph, a first pressure causing the start of the chronograph mechanism, a second one stop and a third one zeroing the needles. To control these functions, just press on the end 32c of the lever 32 with a finger. It will be noted that the form concave of this end allows to properly position the loaded finger to apply the pressure.

La présence de ce levier 32 fait que la force à appliquer pour commander le poussoir n'est pas orientée selon l'axe de ce poussoir. Un tel décalage est favorable. En effet, la couronne de mise à l'heure se trouve généralement à 3 heures, ce qui correspond à la position la plus favorable pour remonter la montre. Cette orientation est, par contre peu propice à exercer une pression. En outre, comme le poussoir dépasse de la couronne, il existe un risque d'accrochage.The presence of this lever 32 makes the force to be applied to control the pusher is not oriented along the axis of this pusher. Such a shift is favorable. In fact, the time setting ring is generally at 3 hours, which corresponds to the most favorable position to go up the shows. This orientation is, on the other hand, not very conducive to exerting pressure. In addition, as the pusher protrudes from the crown, there is a risk hooking.

Ce risque est éliminé en plaçant la couronne à 9 heures. De plus, la présence du levier permet de décaler l'orientation de la force à appliquer selon la direction 8 heures-2 heures, ce qui est nettement plus favorable.This risk is eliminated by placing the crown at 9 o'clock. In addition, the presence the lever is used to shift the orientation of the force to be applied according to the 8 to 2 o'clock direction, which is significantly more favorable.

Dans le mode de réalisation du dispositif représenté aux figures 3 et 4, on retrouve la boíte 10, la carrure 12, le tube 14, la tige 16, le poussoir 18, la couronne 20 et le levier 32. Dans cette configuration, la couronne 20 se trouve à l'extérieur, alors que le poussoir 18, intercalé entre le tube 14 et la tige 16, est de forme annulaire et s'arrête, axialement, au-delà du tube 14, mais laissant, entre lui et la couronne, un espace dans lequel est logé le levier 32.In the embodiment of the device shown in FIGS. 3 and 4, found the box 10, the middle part 12, the tube 14, the rod 16, the pusher 18, the 20 and the lever 32. In this configuration, the crown 20 is located outside, while the pusher 18, interposed between the tube 14 and the rod 16, is annular in shape and stops, axially, beyond the tube 14, but leaving, between him and the crown, a space in which is housed the lever 32.

La carrure 12 comporte un plot 12a muni d'un trou 12b et d'une fente 12c. L'extrémité 32a du levier 32, percée d'un trou 32d, est glissée dans la fente 12c et montée pivotante sur le plot au moyen d'une goupille 34 engagée à force dans l'un ou l'autre des trous 12b et 32d.The middle part 12 comprises a stud 12a provided with a hole 12b and a slot 12c. The end 32a of the lever 32, pierced with a hole 32d, is slid into the slot 12c and pivotally mounted on the stud by means of a pin 34 engaged to in one or the other of the holes 12b and 32d.

Ce deuxième mode de réalisation permet de placer le poussoir dans une position normalement inaccessible à une pression d'un doigt, tout en simplifiant considérablement la structure de l'ensemble, et plus particulièrement de la couronne et du poussoir. De plus, il n'est plus nécessaire d'avoir un étrier pour retenir le levier, celui-ci étant maintenu par la couronne.This second embodiment makes it possible to place the pusher in a normally inaccessible position at the touch of a finger, while greatly simplifying the structure of the whole, and more particularly of the crown and the pusher. Moreover, it is no longer necessary to have a stirrup to hold the lever, the latter being maintained by the crowned.
