The lower end of the piston 46 cooperates with a recess 49 provided in the stretcher 20, while the head of the piston 46 is in contact with a first return 50 which is rotatably mounted around a screw 51 arranged horizontally in the middle part 21.

Ce premier renvoi 50 actionne un second renvoi 52 monté grâce à un roulement à billes sur un arbre vertical 53 de la carrure (fig. 4A). Le second renvoi 52 entraîne un levier 54 monté sur un arbre vertical 55 de la carrure par l'intermédiaire d'un roulement à billes. L'extrémité recourbée 56 du levier 54 est destinée à actionner la commande 40 ou 41 du mouvement 23. Les deux mécanismes d'actionnement 44, 45 possèdent une construction identique et symétrique par rapport à un plan de symétrie passant par 3 heures et 9 heures, l'un 44 actionnant la commande 40 de départ/arrêt, l'autre 45 la commande 41 de remise à zéro du chronographe.This first reference 50 actuates a second return 52 mounted by means of a ball bearing on a vertical shaft 53 of the middle part (FIG 4A). The second return 52 drives a lever 54 mounted on a vertical shaft 55 of the middle part by means of a ball bearing. The curved end 56 of the lever 54 is intended to actuate the control 40 or 41 of the movement 23. The two actuating mechanisms 44, 45 have an identical and symmetrical construction with respect to a plane of symmetry passing through 3 hours and 9 hours one 44 actuating the command 40 start / stop, the other 45 the control 41 reset the chronograph.

Le mouvement de basculement de la partie mobile 11 suivant les deux sens opposés est limité grâce à deux butées réglables 60 montées par vissage dans le brancard 20 à 6 heures et 12 heures (figure 5).The tilting movement of the movable portion 11 in the two opposite directions is limited by two adjustable stops 60 mounted by screwing into the stretcher 20 at 6 o'clock and 12 o'clock (Figure 5).

L'amplitude de mouvement des leviers 56 est limitée par des vis butée 61 montées sur la carrure 21 (figure 4B).The amplitude of movement of the levers 56 is limited by stop screws 61 mounted on the middle part 21 (FIG. 4B).

Pour stabiliser et équilibrer la partie mobile 11 dans son mouvement de basculement, la carrure 21 est munie de deux poussoirs d'équilibrage 62 (fig. 2 et 6) montés à côté des deux pistons 46 et destinés à coopérer élastiquement avec des creusures 63 prévues dans le brancard 20.In order to stabilize and balance the moving part 11 in its tilting movement, the middle part 21 is provided with two balancing levers 62 (FIGS 2 and 6) mounted next to the two pistons 46 and intended to cooperate elastically with recesses 63 provided for in the stretcher 20.

La pièce d'horlogerie comprend en outre un mécanisme de sélection 66 (figures 2 et 7) monté sur la carrure 21 et comportant un curseur 67 destiné à être actionné par l'utilisateur et un coulisseau 68 vissé sur le curseur.The timepiece further comprises a selection mechanism 66 (Figures 2 and 7) mounted on the middle part 21 and having a slider 67 to be actuated by the user and a slider 68 screwed on the slider.

La face inférieure du coulisseau 68 présente une creusure 69 et est destinée à coopérer avec trois goupilles 70, 71, 72 chassées dans des alésages du brancard 20 pour réaliser une sélection des mouvements de la partie mobile (11).The lower face of the slider 68 has a recess 69 and is intended to cooperate with three pins 70, 71, 72 driven into bores of the stretcher 20 to perform a selection of the movements of the movable part (11).

Dans la position médiane illustrée à la figure 7, aucune des goupilles n'est en contact avec le coulisseau 68, la partie mobile 11 peut donc être pivotée dans les deux sens pour commander les deux fonctions de chronographe départ/arrêt et remise à zéro.In the middle position illustrated in Figure 7, none of the pins is in contact with the slide 68, the movable portion 11 can be rotated in both directions to control the two start / stop chronograph functions and reset.

Lorsque le curseur 67 est poussé vers la droite à la figure 7, la goupille 72 de droite est en contact avec le coulisseau 68 et la partie mobile 11 peut donc uniquement effectuer un mouvement de basculement suivant un sens anti-horaire autour de l'axe de pivotement 32. Un mouvement suivant le sens horaire est empêché. Dans cette position la commande de la fonction départ/arrêt est possible, tandis que la commande de la fonction de remise à zéro est empêchée.When the slider 67 is pushed to the right in FIG. 7, the pin 72 on the right is in contact with the slider 68 and the moving part 11 can therefore only perform a tilting movement in a counter-clockwise direction about the axis. of pivoting 32. A clockwise movement is prevented. In this position the command of the start / stop function is possible, while the control of the reset function is prevented.

En plaçant le curseur à gauche à la figure 7, les goupilles 70 et 71 sont en contact avec le coulisseau 68 et la partie mobile 11 ne peut être basculée, donc aucune fonction de commande de chronographe ne peut être réalisée.By placing the slider to the left in FIG. 7, the pins 70 and 71 are in contact with the slider 68 and the moving part 11 can not be tilted, so no chronograph control function can be performed.

La figure 7 montre en outre l'assemblage des parties du brancard 20 comportant les deux portions de cornes 14, 15 vissées au châssis 12 grâce aux vis 16. Les faces en regard 75,76 du brancard 20 et de la partie mobile 11 sont usinées de façon à former des surfaces cylindriques à base sphérique avec un interstice très faible permettant un coulissement l'une par rapport à l'autre lors du mouvement de basculement autour de l'axe de pivotement 32 qui constitue l'axe central des surfaces cylindriques.FIG. 7 further shows the assembly of the parts of the stretcher 20 comprising the two horn portions 14, 15 screwed to the frame 12 by means of the screws 16. The facing faces 75, 76 of the stretcher 20 and of the movable part 11 are machined so as to form cylindrical surfaces with a spherical base with a very small gap allowing sliding relative to each other during the tilting movement about the pivot axis 32 which constitutes the central axis of the cylindrical surfaces.

En référence aux figures 8A, 8B et 8C, ce mouvement de basculement est à peine visible du fait de l'interstice très faible entre les parties fixe et mobile 10,11.With reference to FIGS. 8A, 8B and 8C, this tilting movement is barely visible because of the very small gap between the fixed and mobile parts 10, 11.

Les positions de commande de la fonction départ/arrêt (figure 8B) par pression à 12 heures et de la fonction remise à zéro (fig. 8C) par pression à 6 heures se distinguent à peine de la position de repos intermédiaire de la partie mobile 11 (fig. 8A). Grâce à ce mécanisme de basculement autour d'un axe de pivotement 32 bien défini, on obtient un fonctionnement précis et une commande des fonctions très aisée, même avec des gants, tout en évitant des boutons poussoirs gênants et encombrants.The control positions of the start / stop function (FIG. 8B) by pressing at 12 o'clock and the resetting function (FIG 8C) by pressing at 6 o'clock are hardly distinguishable from the intermediate rest position of the moving part. 11 (Fig. 8A). Thanks to this tilting mechanism around a well-defined pivot axis 32, precise operation and easy control of functions are achieved, even with gloves, while avoiding troublesome and bulky push buttons.

Les figures 3C et 7 montrent que la face inférieure du brancard tournée vers le poignet de l'utilisateur présente une partie médiane concave 80 assurant un confort élevé de port. Cette partie médiane est entourée par une partie périphérique 81 plate permettant une position stable de la pièce d'horlogerie disposée sur un support plat.Figures 3C and 7 show that the underside of the stretcher facing the wrist of the user has a concave middle part 80 ensuring a high wearing comfort. This middle portion is surrounded by a flat peripheral portion 81 for a stable position of the timepiece disposed on a flat support.

Il est bien entendu que le mode de réalisation décrit ci-dessus ne présente aucun caractère limitatif et qu'il peut recevoir toutes modifications désirables à l'intérieur du cadre tel que défini par la revendication 1. En particulier, les commandes du mouvement pourront être de toute autre nature, telle que celle d'une montre à répétition, d'une montre à sonnerie, d'une montre à rattrapante, d'une montre à compteurs, d'une montre à deux ou plusieurs fuseaux horaires, etc. Le brancard et la partie mobile pourront présenter une toute autre construction.It is understood that the embodiment described above is not limiting and that it can receive any desirable modifications within the frame as defined by claim 1. In particular, the controls of the movement can be of any other nature, such as that of a repeater watch, a bell watch, a split watch, a meter watch, a watch with two or more time zones, etc. The stretcher and the moving part may have a completely different construction.

La montre pourrait également présenter un double brancard à axes de pivotement croisés permettant des mouvements de basculement autour de deux axes de pivotement perpendiculaires. Les mécanismes d'actionnement et les moyens de sélection pourront avoir une toute autre construction.The watch could also have a double stretcher with crossed pivot axes allowing tilting movements around two perpendicular pivot axes. The actuating mechanisms and the selection means may have a completely different construction.
