Abstract

The rotatable watch face supports a ring(57) having bosses(57a) which actuate two push buttons(60,67) so that they make contact with contact strip pairs(66,69) respectively. When the watch face is rotated in one direction, one of the push buttons(67) is actuated to short circuit one pair of contacts(69) and a pulse is sent to the watch microprocessor. On continuation of face rotation the first contact pair(69) remains short circuited and the second push button(60) is actuated to close the second contact pair (66), which sends a new pulse to the microprocessor. Continuation of rotation moves the push button(67) off the contacts(69) which again sends a pulse, whilst the contact pair(66) is still closed by the button(60). Further rotation of the watch face causes the button (60) to move off the contacts(66) and another pulse is sent to the microprocessor. Only when the rotation cycle has been completed is the microprocessor in a state to execute its function. Rotation of the face ring in the opposite direction produces the opposite effect.

La montre représentée à la fig. 1, désignée d'une façon générale par 1, est munie d'un dispositif d'affichage analogique comprenant une aiguille de 12 heures 2, fonctionnant en synchronisme avec une aiguille de minutes 3, une aiguille de 24 heures 4, et une aiguille de secondes 5. Son cadran, désigné par 6, comprend un tour de 12 heures 7, avec lequel coopère l'aiguille 2, et un tour de 24 heures 8, avec lequel coopère l'aiguille 4. La mise à l'heure s'effectue à l'aide d'une couronne 9. La montre 1 est en outre munie d'un dispositif d'affichage digital comprenant une cellule à cristaux liquides (LCD) 10 indiquant, dans l'état de fonctionnement dans lequel la montre est représentée à la fig. 1, le jour de la semaine en 11, le quantième en 12 et le temps de la journée, avant ou après midi, en 13.The watch shown in fig. 1, generally designated by 1, is provided with an analog display device comprising a 12-hour hand 2, operating in synchronism with a minute hand 3, a 24-hour hand 4, and a seconds 5. Its dial, designated by 6, includes a 12 hour lap 7, with which the hand 2 cooperates, and a 24-hour turn 8, with which the hand 4 cooperates. The time is set using a crown 9. The watch 1 is further provided of a digital display device comprising a liquid crystal cell (LCD) 10 indicating, in the operating state in which the watch is shown in FIG. 1, the day of the week in 11, the date in 12 and the time of day, before or after noon, in 13.

La commande des dispositifs d'affichage ne sera pas décrite ici en détail, hormis pour ce qui est des moyens mis en oeuvre à cet effet nécessaires à la compréhension de l'invention, étant connue en soi.The control of the display devices will not be described here in detail, except as regards the means used for this purpose necessary for understanding the invention, being known per se.

La boite de la montre 1, visible principalement à la fig. 5, comprend une carrure-lunette 14 dans laquelle se visse un fond 15, avec interposition d'une garniture d'étanchéité 16, et qui présente une partie 14a en forme de manchette dans laquelle est chassée une glace saphir ou minérale 17, avec interposition d'une garniture d'étanchéité 18. La manchette 14a de la carrure 14 porte, extérieurement, une lunette tournante 19 maintenue en place par une bague à épaulement 20 chassée sur cette manchette.The watch case 1, visible mainly in fig. 5, comprises a middle part-bezel 14 into which a base 15 is screwed, with the interposition of a seal 16, and which has a part 14a in the form of a cuff in which a sapphire or mineral crystal 17 is expelled, with interposition of a seal 18. The cuff 14 has the middle part 14, externally, a rotating bezel 19 held in place by a shoulder ring 20 driven onto this cuff.

Le mouvement de la montre, désigné d'une façon générale par 21, est maintenu en place dans la carrure-lunette 14 par des brides 22 fixées par des vis 23.The movement of the watch, generally designated by 21, is held in place in the middle-bezel 14 by flanges 22 fixed by screws 23.

Ce mouvement est électronique et comprend une pile électrique d'alimentation 24 (fig. 2), un microprocesseur 25, un garde-temps 26 constitué par un oscillateur à quartz et quatre moteurs électriques 27, 28, 29 et 30 actionnant respectivement les aiguilles de 12 heures 2, de minutes 3, de secondes 5 et de 24 heures 4. La liaison entre le rotor de chacun de ces moteurs et chacune de ces aiguilles est assurée par des trains d'engrenages visibles en plan à la fig. 2. Seul l'un d'entre deux, celui qui relie le moteur 27 à l'aiguille 2, sera décrit ici en détail, les autres étant identiques ou analogues.This movement is electronic and includes an electric supply battery 24 (fig. 2), a microprocessor 25, a timepiece 26 constituted by a quartz oscillator and four electric motors 27, 28, 29 and 30 respectively actuating the hands. 12 hours 2, minutes 3, seconds 5 and 24 hours 4. The connection between the rotor of each of these motors and each of these needles is ensured by gear trains visible in plan in FIG. 2. Only one of the two, that which connects the motor 27 to the needle 2, will be described here in detail, the others being identical or analogous.

Ainsi, le rotor du moteur 27,désigné par 31(fig.3), porte un pignon 32 en prise avec la roue, désignée par 33, d'un premier mobile intermédiaire dont le pignon, désigné par 34, est en prise avec la roue 35 d'un second mobile intermédiaire dont le pignon, désigné par 36, est en prise avec une roue à canon des heures, désignée par 37, dont le canon 37a porte l'aiguille de 12 heures 2. Le rotor 31 et le premier mobile intermédiaire sont pivotés entre un pont de rouage 38 et la platine du mouvement, désignée par 39. Le deuxième mobile intermédiaire est pivoté entre un pont intermédiaire 40 et un pont de centre 41.Thus, the rotor of the motor 27, designated by 31 (fig. 3), carries a pinion 32 engaged with the wheel, designated by 33, of a first intermediate mobile whose pinion, designated by 34, is engaged with the wheel 35 of a second intermediate mobile whose pinion, designated by 36, is engaged with an hour barrel wheel, designated by 37, whose barrel 37a carries the 12 hour hand 2. The rotor 31 and the first intermediate mobile are pivoted between a gear train bridge 38 and the movement plate, designated by 39. The second intermediate mobile is pivoted between an intermediate bridge 40 and a center bridge 41.

Les différents moteurs forment, avec leur stator, dont celui du moteur 27 est visible en 42 à la fig. 3, avec un pont inférieur 43 (fig.4), et avec la plaque (PCB), désignée par 44, d'un circuit intégré 45, un module indépendant assemblé à l'aide de quatre paires de vis 46 prenant dans quatre paires de canons 47, formant piliers, sertis dans le pont inférieur 43. Les vis 46 et piliers 47 de chaque paire sont situés aux deux extrémités de chaque moteur. Ce module se fixe à la platine 39 à l'aide de vis 48 prenant dans des canons 49, formant entretoises, chassés dans la platine 39.The different motors form, with their stator, of which that of the motor 27 is visible at 42 in FIG. 3, with a lower bridge 43 (fig. 4), and with the plate (PCB), designated by 44, of an integrated circuit 45, an independent module assembled using four pairs of screws 46 taking in four pairs cannons 47, forming pillars, crimped in the lower bridge 43. The screws 46 and pillars 47 of each pair are located at the two ends of each motor. This module is fixed to the plate 39 by means of screws 48 taking in barrels 49, forming spacers, driven into the plate 39.

Le microprocesseur 25 est également porté par la plaque 44 du circuit intégré 45 (fig. 4), de même que la cellule à cristaux liquides (LCD) 10. Celle-ci est fixée à la plaque 44 du circuit intégré avec interposition de deux contacteurs Zebra 50, formant entretoises, au moyen d'une bride de maintien 51. La fig. 4a montre que labride 51 est fixée à la platine 39 à l'aide de vis 52.The microprocessor 25 is also carried by the plate 44 of the integrated circuit 45 (fig. 4), as does the liquid crystal cell (LCD) 10. This is fixed to the plate 44 of the integrated circuit with the interposition of two contactors Zebra 50, forming spacers, by means of a retaining flange 51. FIG. 4 a shows that the flange 51 is fixed to the plate 39 using screws 52.

Il est rappelé ici que les contacteurs Zebra sont constitués par des blocs parallélépipédiques de matière isolante présentant des bandes annulaires métallisées constituant des pistes conductrices. Dans le cas d'espèce, les contacteurs Zebra 50 sont en contact avec la face interne de la cellule à cristaux liquides 10 et avec la face interne de la plaque de circuit intégré 44, assurant la liaison électrique entre ces deux éléments.It is recalled here that the Zebra contactors consist of parallelepipedal blocks of insulating material having metallized annular strips constituting conductive tracks. In this case, the Zebra contactors 50 are in contact with the internal face of the liquid crystal cell 10 and with the internal face of the integrated circuit plate 44, ensuring the electrical connection between these two elements.

L'introduction d'informations dans le microprocesseur 25 s'effectue à l'aide de la lunette tournante 19. Cette dernière porte, sur sa face externe, un disque annulaire mince 53 (fig. 5) logé à l'intérieur d'un rebord extérieur 19a de la lunette, dans lequel il est serti, et dont une cheville 54, chassée dans ladite lunette, assure l'orientation angulaire. Ce disque annulaire 53 est divisé en deux zones concentriques 55, elles-mêmes divisées en segments correspondant à des fuseaux-horaires (fig. 1), lesquels sont munis d'indications géographiques 56 qui permettent de les identifieThe information is entered into the microprocessor 25 using the rotating bezel 19. The latter carries, on its external face, a thin annular disc 53 (fig. 5) housed inside a outer flange 19a of the bezel, in which it is crimped, and having a peg 54, driven in said bezel, ensures the angular orientation. This annular disc 53 is divided into two concentric zones 55, themselves divided into segments corresponding to time zones (fig. 1), which are provided with geographical indications 56 which make it possible to identify them

La lunette tournante 19 porte, sur sa face interne tournée vers la carrure 14 de la boite, une bague 57 dont la face interne présente des bossages 57a (figs. 5 et 6) alternant avec des creusures 58. Cette bague 57 présente des tétons 57b engagés dans des logements correspondants de la lunette 19, ce qui assure son orientation. La carrure 14 porte un manchon 59 dans lequel est logé un poussoir 60, portant une garniture d'étanchéité (O-ring) 61. Ce poussoir est mobile dans le manchon 59 et se déplace perpendiculairement au plan du mouvement. Un ressort de rappel 62 maintient le poussoir 60 en contact avec la bague 57. Ce ressort à boudin prend appui sur une bague 63 sertie à l'extrémité du manchon 59. L'extrémité interne du poussoir 60 porte une bague 64 sur laquelle est collée une bague 65 en caoutchouc conducteur destinée à coopérer, lorsque le poussoir 60 est déplacé par les bossages 57a de la bague 57, avec une paire de lames de contact 66 (figs. 2 et 5) en liaison avec le microprocesseur 25 (fig. 11).The rotating bezel 19 carries, on its internal face turned towards the middle part 14 of the case, a ring 57 whose internal face has bosses 57 a (figs. 5 and 6) alternating with recesses 58. This ring 57 has studs 57 b engaged in corresponding housings of the telescope 19, which ensures its orientation. The middle part 14 carries a sleeve 59 in which is housed a pusher 60, carrying a seal (O-ring) 61. This pusher is movable in the sleeve 59 and moves perpendicular to the plane of movement. A return spring 62 keeps the pusher 60 in contact with the ring 57. This coil spring bears on a ring 63 crimped at the end of the sleeve 59. The internal end of the pusher 60 carries a ring 64 on which is stuck a ring 65 of conductive rubber intended to cooperate, when the pusher 60 is moved by the bosses 57 a of the ring 57, with a pair of contact blades 66 (figs. 2 and 5) in connection with the microprocessor 25 (fig. 11).

La carrure 14 porte un deuxième dispositif à contacteurs identique à celui décrit ci-dessus et représenté à la fig. 5, diamétralement opposé au premier, avec un léger décalage, dont la tête du poussoir, désignée par 67, est visible aux figs. 6 à 10. La bague de caoutchouc conducteur située à l'extrémité interne de ce poussoir, désignée par 68 (fig. 11), coopère avec une paire de lames de contact 69 (figs. 2 et 11) reliées au microprocesseur 25.The middle part 14 carries a second contactor device identical to that described above and shown in FIG. 5, diametrically opposite to the first, with a slight offset, the head of the pusher, designated by 67, is visible in Figs. 6 to 10. The conductive rubber ring situated at the internal end of this pusher, designated by 68 (fig. 11), cooperates with a pair of contact blades 69 (figs. 2 and 11) connected to the microprocessor 25.

Le nombre des bossages 57a de la bague 57 portée par la lunette tournante 19 est pair de telle manière que, lorsque cette bague est en position de repos, l'un des poussoirs 60 et 67 soit disposé d'un côté d'un bossage 57a et l'autre de l'autre côté du bossage 57a opposé. Cet agencement est schématiquement illustré à la fig. 6 où la bague 57 est partiellement représentée à l'état développé.The number of bosses 57 a of the ring 57 carried by the rotating bezel 19 is even so that, when this ring is in the rest position, one of the pushers 60 and 67 is disposed on one side of a boss 57 a and the other on the other side of the boss 57 a opposite. This arrangement is schematically illustrated in FIG. 6 where the ring 57 is partially shown in the developed state.

Ainsi, les poussoirs 60 et 67 non seulement assurent le court-circuitage et la rupture du court-circuitage des paires de contacts 66 et 69, respectivement, mais jouent en outre le rôle de sautoirs assurant la stabilité (indexage) des positions d'arrêt de la lunette tournante 19.Thus, the pushers 60 and 67 not only ensure the short-circuiting and the breaking of the short-circuiting of the pairs of contacts 66 and 69, respectively, but also play the role of jumpers ensuring the stability (indexing) of the stop positions. of the rotating bezel 19.

Dans les figs. 7 à 10, les deux poussoirs ont été représentés séparés l'un de l'autre d'une distance correspondant à la largeur d'un seul bossage 57a de la bague 57, alors même qu'ils sont diamétralement opposés, avec un léger décalage, ceci pour la clarté de l'exposé. En fait, les deux poussoirs pourront être placés dans une position relative quelconque, pourvu qu'ils soient séparés par une distance qui corresponde à un multiple du pas de la partie festonnée de la bague 57a, plus un léger décalage correspondant à la largeur de deux demi-poussoirs, c'est-à-dire d'un poussoir.In figs. 7 to 10, the two pushers are shown separated from each other by a distance corresponding to the width of a single boss 57a of the ring 57, while they are diametrically opposed with a slight shift, this for the clarity of the presentation. In fact, the two pushers can be placed in any relative position, provided that they are separated by a distance which corresponds to a multiple of the pitch of the scalloped part of the ring 57 a , plus a slight offset corresponding to the width of two half-pushers, that is to say one pushbutton.

Ces figures montrent que lorsque la lunette 19 est déplacée en rotation dans un sens ou dans l'autre, par exemple dans le sens des flèches 70 de ces figures, l'un des poussoirs 60 et 67, dans le cas d'espèce le poussoir 67, est actionné le premier et court-circuite les lames de contact 69. Le poussoir 60 n'est alors pas actionné (fig. 8). Le déplacement de la lunette tournante 19 se poursuivant dans le même sens, le poussoir 67 reste actionné et le poussoir 60 l'est à son tour, court-circuitant la paire de lames de contact 66 (fig. 9). La poursuite du déplacement de la lunette 19, toujours dans le même sens, amène le poussoir 67 à quitter les lames 69 qui, ainsi, ne sont plus court-circuitées,alors que le poussoir 60 reste en position de travail, le court-circuitage des lames de contact 66 se maintenant (fig. 10). Enfin, le déplacement de la lunette tournante se poursuivant encore, les deux poussoirs 60 et 67 sont relâchés et reviennent en position de repos, telle que représenté à la fig. 7, les deux paires de lames 66 et 69 n'étant alors plus court-circuitées. Si, au contraire, la lunette 19 est tournée en sens opposé à celui des flèches 70 des figs. 7 à 10, le même cycle d'opérations se répète, mais le rôle des poussoirs 60 et 67 est alors inversé.These figures show that when the telescope 19 is rotated in one direction or the other, for example in the direction of the arrows 70 of these figures, one of the pushers 60 and 67, in this case the pushbutton 67, the first is actuated and short-circuits the contact blades 69. The pusher 60 is then not actuated (fig. 8). The movement of the rotating bezel 19 continuing in the same direction, the pusher 67 remains actuated and the pusher 60 is in turn short-circuiting the pair of contact blades 66 (fig. 9). Continued movement of the bezel 19, always in the same direction, causes the pusher 67 to leave the blades 69 which, thus, are no longer short-circuited, while the pusher 60 remains in the working position, short-circuiting contact blades 66 now (fig. 10). Finally, the movement of the rotating bezel still continuing, the two pushers 60 and 67 are released and return to the rest position, as shown in FIG. 7, the two pairs of blades 66 and 69 then no longer being short-circuited. If, on the contrary, the telescope 19 is turned in the opposite direction to that of the arrows 70 of FIGS. 7 to 10, the same cycle of operations is repeated, but the role of pushers 60 and 67 is then reversed.

Chaque court-circuitage et rupture de court-circuitage des lames de contacts 66 et 69 produisant l'envoi d'impulsions de commande au microprocesseur 25, celui-ci pourra ainsi détecter le sens dans lequel est actionnée la lunette tournante 19 et en tenir compte pour ce qui est des informations qu'il envoie aux dispositifs d'affichage de la montre. De plus l'agencement sera tel que ce n'est qu'une fois effectué le cycle complet des opérations illustrées par les figs. 7 à 10 que le microprocesseur pourra accomplir la fonction qui lui aura été dictée. Ainsi, des fausses manipulations interrompues en cours d'exécution, par exemple, resteront sans effet.Each short circuit and short circuit break of the contact blades 66 and 69 producing the sending of control pulses to the microprocessor 25, the latter will thus be able to detect the direction in which the rotating bezel 19 is actuated and to take it into account in terms of the information it sends to the watch display devices. In addition, the arrangement will be such that it is only once the complete cycle of the operations illustrated in FIGS has been carried out. 7 to 10 that the microprocessor will be able to accomplish the function dictated to him. Thus, false manipulations interrupted during execution, for example, will have no effect.

La fig.11 illustre schématiquement les liaisons entre le microprocesseur 25 et les paires de lames de contact 66 et 69, entre le microprocesseur et les moteurs 27, 28, 29 et 30, entre le microprocesseur et la cellule à cristaux liquides 10 par l'intermédiaire d'un décodeur multiple 71 et, enfin, entre la couronne de mise à l'heure 9 et le microprocesseur par l'intermédiaire d'un bloc de contacteurs 72.Fig. 11 schematically illustrates the connections between the microprocessor 25 and the pairs of contact blades 66 and 69, between the microprocessor and the motors 27, 28, 29 and 30, between the microprocessor and the liquid crystal cell 10 by the via a multiple decoder 71 and, finally, between the time setting crown 9 and the microprocessor via a block of contactors 72.

Dans l'exemple représenté, la position angulaire de la lunette 19 détermine, par l'intermédiaire du microprocesseur 25 et du moteur 27, la position de l'aiguille de 12 heures 4. L'agencement est tel qu'en tournant la lunette 19 et son disque 53 de manière à amener une des 24 indications de fuseau horaire 56 en regard du point correspondant à 12 heures du tour d'heures 7, l'aiguille 4 est automatiquement amenée à la position qui désigne l'heure dans ledit fuseau horaire.In the example shown, the angular position of the bezel 19 determines, via the microprocessor 25 and the motor 27, the position of the 12-hour hand 4. The arrangement is such that by turning the bezel 19 and its disc 53 so as to bring one of the 24 time zone indications 56 opposite the point corresponding to 12 o'clock in the hour circle 7, the hand 4 is automatically brought to the position which designates the time in said time zone .

A cet effet, la bague 57 présente 24 bossages 57a correspondant aux 24 fuseaux horaires. En désignant par 0 et 1 repectivement l'état ouvert (non court-cicuité) et l'état fermé (court-circuité) des paires de contacts 66 et 69, la rotation de la lunette dans le sens des flèches 70 provoque l'envoi au microprocesseur 25 d'impulsions de commande correspondant à la séquence ci-dessous: contacts 66 contacts 69 état de repos 0 0 état 1 0 1 état 2 1 1 état 3 1 0 état de repos 0 0 For this purpose, the ring 57 has 24 protrusions 57a corresponding to the 24 time zones. By designating by 0 and 1 respectively the open state (not short-cicuity) and the closed state (short-circuited) of the pairs of contacts 66 and 69, the rotation of the telescope in the direction of the arrows 70 causes the sending of control pulses corresponding to the sequence below to the microprocessor 25: contacts 66 contacts 69 resting state 0 0 state 1 0 1 state 2 1 1 state 3 1 0 resting state 0 0

Le microprocesseur 25 est programmé pour que chaque telle séquence provoque l'envoi au moteur 27 d'impulsions qui font avancer l'aiguille 4 d'une heure.The microprocessor 25 is programmed so that each such sequence causes pulses to be sent to the motor 27 which advance the hand 4 by one hour.

A l'inverse, la rotation de la lunette dans le sens opposé génère la séquence d'impulsions ci-dessous: contacts 66 contacts 69 état de repos 0 0 état 1 1 0 état 2 1 1 état 3 0 1 état de repos 0 0 Conversely, rotating the bezel in the opposite direction generates the following pulse sequence: contacts 66 contacts 69 resting state 0 0 state 1 1 0 state 2 1 1 state 3 0 1 resting state 0 0

Le microprocesseur 25 est programmé pour que chaque telle séquence provoque l'envoi au moteur 27 d'impulsions qui font reculer l'aiguille 4 d'une heure.The microprocessor 25 is programmed so that each such sequence causes pulses to be sent to the motor 27 which cause the needle 4 to go back one hour.

Lors de ces séquences, si la date du nouveau fuseau horaire dont l'heure est affichée n'est pas la même que celle du fuseau horaire dont l'heure était précédemment affichée, la nouvelle date sera affichée par le dispositif d'affichage digital 10.During these sequences, if the date of the new time zone whose time is displayed is not the same as that of the time zone whose time was previously displayed, the new date will be displayed by the digital display device 10.

L'invention vient d'être décrite en se référant à une montre à fuseaux horaires mais il va de soi qu'elle s'applique à tout type de montre possédant plusieurs modes de fonctionnement, comme par exemple une montre chronographe. Das ce cas, la lunette 19 porte sur son disque 53, en plus de l'indication correspondant au mode montre (par exemple, LOCAL TIME), plusieurs indications correspondant aux différents modes de fonctionnement en chronographe (par exemple, SPLIT, LAP, RESTART, DOWN, DELTA, REGATE, RALLY). Le nombre de bossages 57a est alors égal au nombre total de modes de fonctionnement de la pièce ( soit 8 dans l'exemple donné). La sélection du mode se fait par la rotation de la lunette. Chaque séquence d'impulsions ainsi produites pour amener une indication du disque 53 en regard du point correspondant à 12 heures du tour d'heures 7 fait passer la montre au mode de fonctionnement correspondant à l'indication adjacente du disque 53, soit à gauche, soit à droite, selon le sens de la rotation.The invention has just been described with reference to a time zone watch but it goes without saying that it applies to any type of watch having several operating modes, such as for example a chronograph watch. In this case, the bezel 19 carries on its disc 53, in addition to the indication corresponding to the watch mode (for example, LOCAL TIME), several indications corresponding to the different operating modes in chronograph (for example, SPLIT, LAP, RESTART , DOWN, DELTA, REGATE, RALLY). The number of bosses 57a is then equal to the total number of operating modes of the part (ie 8 in the example given). The mode is selected by rotating the bezel. Each pulse sequence thus produced to bring an indication of the disc 53 opposite the point corresponding to 12 hours of the hour turn 7 switches the watch to the operating mode corresponding to the adjacent indication of the disc 53, either on the left, either to the right, depending on the direction of rotation.
