L'invention concerne un mécanisme d'affichage d'horlogerie comportant au moins un rouleau pivotant autour d'un axe de rouleau, le rouleau comportant au moins un volet pivotant autour d'un axe de volet parallèle à l'axe de rouleau et distinct de l'axe de rouleau, ledit au moins un volet comportant au moins une première face et au moins une deuxième face, le mécanisme d'affichage comportant des premiers moyens d'entraînement pour faire pivoter le rouleau autour de l'axe de rouleau, où ledit mécanisme d'affichage comporte des deuxièmes moyens d'entraînement distincts desdits premiers moyens d'entraînement pour faire pivoter au moins un dit volet autour de son dit axe de volet, dans au moins une position déterminée dudit axe de volet par rapport audit axe de rouleauThe invention relates to a clock display mechanism comprising at least one roller pivoting about a roller axis, the roller comprising at least one flap pivoting about a flap axis parallel to the roller axis and distinct the roller axis, said at least one flap having at least a first face and at least a second face, the display mechanism including first drive means for rotating the roller about the roller axis, wherein said display mechanism has second drive means separate from said first drive means for rotating at least one said flap about said flap axis thereof in at least one determined position of said flap axis with respect to said axis. of roll

L'invention concerne encore une montre comportant au moins un tel mécanisme d'affichage.The invention also relates to a watch comprising at least one such display mechanism.

L'invention concerne le domaine des mécanismes d'affichage d'horlogerie, notamment pour montres, et plus particulièrement les mécanismes d'affichage de calendrier.The invention relates to the field of watch display mechanisms, particularly for watches, and more particularly the calendar display mechanisms.

Arrière-plan de l'inventionBackground of the invention

La lisibilité des affichages est une préoccupation majeur en horlogerie, surtout pour les affichages de type calendrier, qui sont difficiles à réaliser dans des formats facilement visibles et déchiffrables par l'utilisateur.The readability of displays is a major concern in watchmaking, especially for calendar type displays, which are difficult to achieve in easily visible and user-readable formats.

Les affichages horlogers sont rarement réalisés par rouleaux car les indications sous cette forme sont gourmandes en épaisseur, en raison du diamètre du rouleau, comportant par exemple jusqu'à 31 indications pour les jours du mois, ou 52 indications pour les semaines de l'année, et incompatibles avec la géométrie particulière d'une montre.The clock displays are rarely made by rolls because the indications in this form are greedy in thickness, because of the diameter of the roll, comprising for example up to 31 indications for the days of the month, or 52 indications for the weeks of the year , and incompatible with the particular geometry of a watch.

Et l'emploi éventuel de caractères de très petite taille nécessite l'emploi de loupes dans l'épaisseur de la glace de montre, qui nuisent fortement à l'esthétique de la montre, tout en restant difficiles à lire.And the possible use of characters of very small size requires the use of magnifying glasses in the thickness of the watch ice, which greatly affect the aesthetics of the watch, while remaining difficult to read.

Les affichages à volet ou à palettes, de type statique, pour pendulettes et autres horloges, sont peu transposables à des montres, car faisant généralement appel à la gravité. Ils sont de plus fragiles et ne peuvent supporter les chocs.The shutter or pallet displays, static type, for clocks and other clocks, can not be transposed to watches because usually using gravity. They are more fragile and can not withstand shocks.

Le document US3964428au nom de ARAI KIYOYUKI décrit un indicateur à volets rotatifs à deux faces, en périphérie d'un tambour rotatif, avec des moyens de guidage des volets maintenus orientés tangentiellement. Lors de la rotation du tambour un mécanisme permet le renversement des volets autour de leur axe propre.The document US3964428 by the name of ARAI KIYOYUKI discloses an indicator with two-sided rotating flaps at the periphery of a rotating drum, with means for guiding the flaps held tangentially oriented. When rotating the drum a mechanism allows the flaps to turn around their own axis.

Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

L'invention est illustrée sur les figures, de façon non limitative, avec des rouleaux des jours de la semaine, du quantième (un rouleau des dizaines et un rouleau des unités), et des mois.The invention is illustrated in the figures, without limitation, with rolls of the days of the week, the date (a roll tens and a roll of units), and months.

La figure 1 illustre par exemple, de façon non limitative, une montre comportant des rouleaux, avec une hauteur de caractères supérieure à 2.20mm, sur un rouleau de diamètre 5.00mm.The figure 1 illustrates for example, without limitation, a watch with rollers, with a character height greater than 2.20mm, on a 5.00mm diameter roll.

Ainsi, l'invention concerne un mécanisme d'affichage 100 d'horlogerie comportant au moins un rouleau 10, prenant sur les figures des références différenciées : 11, 12, 13, 14, pivotant autour d'un axe de rouleau D10. Ce rouleau 10, 11, 12, 13, 14 comporte au moins un volet 20, qui est monté pivotant autour d'un axe de volet D20 parallèle à l'axe de rouleau D10 et distinct de l'axe de rouleau D10. Cet au moins un volet 20 comporte au moins une première face 201 et au moins une deuxième face 202, agencées de façon à ce que l'utilisateur puisse visualiser une seule de ces faces à un instant donné.Thus, the invention relates to a 100 clock display mechanism comprising at least one roller 10, taking in the figures differentiated references: 11, 12, 13, 14, pivoting about a roller axis D10. This roller 10, 11, 12, 13, 14 comprises at least one flap 20, which is pivotally mounted about a flap axis D20 parallel to the roller axis D10 and distinct from the roller axis D10. This at least one flap 20 comprises at least a first face 201 and at least a second face 202, arranged so that the user can view only one of these faces at a given instant.

Le mécanisme d'affichage 100 comporte des premiers moyens d'entraînement 31 pour faire pivoter le rouleau 10, 11, 12, 13, 14, autour de l'axe de rouleau D10.The display mechanism 100 includes first drive means 31 for rotating the roller 10, 11, 12, 13, 14 around the roller axis D10.

Ce mécanisme d'affichage 100 comporte des deuxièmes moyens d'entraînement 32, distincts des premiers moyens d'entraînement 31, pour faire pivoter au moins un tel volet 20 autour de son axe de volet D20, dans au moins une position déterminée de l'axe de volet D20 par rapport à l'axe de rouleau D10.This display mechanism 100 comprises second drive means 32, distinct from the first drive means 31, for pivoting at least one such flap 20 about its flap axis D20, in at least one determined position of the flap axis D20 with respect to roller axis D10.

Plus particulièrement, dans ce mécanisme d'affichage 100, une rotation constante des volets 20 en fonction des rouleaux 10, 11, 12, 13, 14, est calculée pour que, à la position d'affichage visible par l'utilisateur, l'indication du volet 20 soit tournée de 180° par tour de rouleau 10, 11, 12, 13, 14.More particularly, in this display mechanism 100, a constant rotation of the flaps 20 as a function of the rollers 10, 11, 12, 13, 14, is calculated so that, in the display position visible to the user, the indication of the flap 20 is rotated 180 ° per roll revolution 10, 11, 12, 13, 14.

Plus particulièrement, les deuxièmes moyens d'entraînement 32 sont agencés pour faire pivoter un seul volet 20 à la fois, indépendamment des autres volets 20 que comporte un rouleau 10, 11, 12, 13, 14.More particularly, the second drive means 32 are arranged to pivot a single flap 20 at a time, independently of the other flaps 20 that comprises a roller 10, 11, 12, 13, 14.

Dans une autre variante, les deuxièmes moyens d'entraînement 32 sont agencés pour faire pivoter de façon synchrone chaque volet 20 que comporte un rouleau 10, 11, 12, 13, 14. Ceci permet d'économiser l'énergie nécessaire au mécanisme d'affichage.In another variant, the second drive means 32 are arranged to synchronously rotate each flap 20 that comprises a roller 10, 11, 12, 13, 14. This saves the energy required for the mechanism display.

Dans la variante préférée, car moins consommatrice d'espace, où les deuxièmes moyens d'entraînement 32 sont agencés pour faire pivoter un seul volet 20 à la fois, plus particulièrement, les deuxièmes moyens d'entraînement 32 sont agencés pour faire pivoter le seul volet 20 en une unique position déterminée de l'axe de volet D20 par rapport à l'axe de rouleau D10.In the preferred embodiment, because less space consuming, where the second drive means 32 are arranged to rotate a single flap 20 at a time, more particularly, the second drive means 32 are arranged to rotate the only one flap 20 in a single determined position of the flap axis D20 with respect to the roller axis D10.

Selon l'invention, les deuxièmes moyens d'entraînement 32 comportent, au niveau de chaque volet 20, au moins un pignon d'entraînement de volet 35 axé sur l'axe de volet D20. Ce pignon d'entraînement de volet 35 est plus particulièrement agencé pour coopérer avec un moyen de commande, que comporte le mécanisme d'affichage 100, pour modifier en séquence ou en continu la position des volets 20 successifs d'un même rouleau 10, 11, 12, 13, 14, ou pour modifier à la demande la position d'un volet 20 déterminé. Il est ainsi possible de modifier à la demande la position d'un volet déterminé.According to the invention, the second drive means 32 comprise, at each flap 20, at least one flap drive gear 35 oriented on the flap axis D20. This flap drive gear 35 is more particularly arranged to cooperate with a control means, which comprises the display mechanism 100, to modify in sequence or continuously the position of the successive flaps 20 of the same roller 10, 11 , 12, 13, 14, or to modify on demand the position of a particular flap 20. It is thus possible to modify on demand the position of a specific component.

Tout particulièrement, une motorisation des deuxièmes moyens d'entraînement 32, ou une commande par une tige de montre, ou un poussoir, une targette, ou similaire, facilite la mise à jour d'un calendrier après un arrêt prolongé d'une montre.In particular, an operator of the second drive means 32, or a control by a watch rod, or a pusher, a bolt, or the like, facilitates the updating of a calendar after a prolonged stop of a watch.

Plus particulièrement, chaque volet 20 comporte, pour son maintien en position d'orientation, une came de volet 25, notamment une came-coeur, comportant autant de points bas 26 que le volet 20 comporte de faces 201, 202. Et le rouleau 10, 11, 12, 13, 14, comporte de préférence au moins un ressort 15 qui est agencé pour exercer un effort sur un sautoir 17 disposé à proximité de chaque came de volet pour l'indexage en position de cette came de volet 25, tel que visible sur les figures 9 et 11.More particularly, each flap 20 comprises, for its maintenance in the orientation position, a flap cam 25, in particular a cam-core, comprising as many low points 26 as the flap 20 has faces 201, 202. And the roller 10 , 11, 12, 13, 14, preferably comprises at least one spring 15 which is arranged to exert a force on a jumper 17 arranged close to each shutter cam for the indexing in position of this shutter cam 25, such as that visible on Figures 9 and 11 .

Dans une variante particulière, tel que visible sur la figure 21, le couple constitué par ce sautoir et ce ressort est avantageusement remplacé par au moins un ressort 15 de forme spéciale, notamment un ressort unique tel qu'illustré, cumulant les deux fonctions de ressort et de sautoir, et qui remplace tous les sautoirs 17 de la variante des figures 9 et 11.In a particular variant, as visible on the figure 21 , the pair constituted by this jumper and this spring is advantageously replaced by at least one spring 15 of special shape, in particular a single spring as illustrated, combining the two functions of spring and jumper, and replacing all the jumpers 17 of the variant of Figures 9 and 11 .

Dans une variante de fonctionnalité similaire, plus particulièrement, chaque volet 20 comporte, pour son maintien en position d'orientation, une came de volet 25 ou une came-coeur comportant autant de points bas 26 que le volet 20 comporte de faces 201, 202, et le rouleau 10, 11, 12, 13, 14 comporte, pour chaque came de volet 25 ou came-coeur, au moins un aimant 70 agencé pour exercer un effort sur la came de volet 25 ou came-coeur en matériau magnétique pour l'indexage en position de la came de volet 25 ou came-coeur, tel que visible sur la figure 17.In a variant of similar functionality, more particularly, each flap 20 comprises, for its maintenance in the orientation position, a shutter cam 25 or a cam-core having as many low points 26 as the shutter 20 has faces 201, 202 , and the roller 10, 11, 12, 13, 14 comprises, for each cam flap 25 or cam-heart, at least one magnet 70 arranged to exert a force on the flap cam 25 or cam-core of magnetic material for indexing in position of the shutter cam 25 or cam-heart, as visible on the figure 17 .

Plus particulièrement, les premiers moyens d'entraînement 31 comportent, tel que visible sur les figures 3 et 4, une roue de commande 3120, 3130 dont certaines dents sont supprimées, et qui engrène avec un pignon d'entraînement de rouleau 312, 313, soit directement, soit par l'intermédiaire d'un couple de réduction 3131, pour obtenir la réduction voulue. Ceci permet notamment l'affichage du quantième.More particularly, the first drive means 31 comprise, as visible on the Figures 3 and 4 , a control wheel 3120, 3130 with some teeth removed, and which meshes with a roller drive gear 312, 313, either directly or via a reduction torque 3131, to achieve the desired reduction . This allows in particular the display of the date.

Plus particulièrement, au moins un rouleau 10, 11, 12, 13, 14, comporte au moins une position fixe d'affichage et au moins une position mobile d'affichage par un volet 20 comportant une pluralité de faces 201, 202, tel que visible sur la figure 16. Ceci permet de réaliser un affichage à rouleau avec toutes sortes d'indications dans un volume réduit.More particularly, at least one roller 10, 11, 12, 13, 14 comprises at least one fixed display position and at least one movable display position by a flap 20 comprising a plurality of faces 201, 202, such as visible on the figure 16 . This allows a roller display with all kinds of indications in a small volume.

Plus particulièrement, les premiers moyens d'entraînement 31 comportent un rouage d'entrée 61 qui entraîne une roue principale 60 dont une révolution correspond à la période temporelle d'affichage du rouleau 10, 11, 12, 13, 14, et qui porte une came principale 50 porteuse de secteurs périphériques 51 séparés par des évidements 52, les secteurs périphériques 51 étant d'amplitude inégale, les plus courts correspondant aux positions fixes d'affichage, et les plus longs correspondant aux positions mobiles d'affichage. La came principale 50 coopère avec une came secondaire 40 en croix de Malte excentrée et agencée pour pivoter lors du passage d'un évidement 52. La came secondaire 40 porte une roue secondaire 42 engrenant avec une roue d'entraînement de rouleau 62. La roue principale 60 porte encore une roue principale d'entraînement de volet 63, laquelle engrène elle-même avec un pignon de volet 64 qui est agencé pour commander un pignon d'entraînement de volet 35 axé sur l'axe de volet D20 ou constituant lui-même un tel pignon d'entraînement de volet 35.More particularly, the first drive means 31 comprise an input gear train 61 which drives a main wheel 60, one revolution of which corresponds to the display time period of the roller 10, 11, 12, 13, 14, and which carries a main cam 50 carrying peripheral sectors 51 separated by recesses 52, the peripheral sectors 51 being of unequal amplitude, the shortest corresponding to the fixed display positions, and the longest corresponding to the mobile display positions. The main cam 50 cooperates with a secondary eccentric Maltese cross cam 40 and arranged to pivot during the passage of a recess 52. The secondary cam 40 carries a secondary wheel 42 meshing with a roller drive wheel 62. The wheel main 60 still carries a shutter drive main wheel 63, which meshes itself with a flap gear 64 which is arranged to control a flap drive gear 35 oriented on the flap axis D20 or itself constituting such a flap drive gear 35.

L'invention concerne encore une montre 1000 comportant au moins un tel mécanisme d'affichage 100.The invention also relates to a watch 1000 comprising at least one such display mechanism 100.

Les figures illustrent des modes de réalisation particuliers de l'invention.The figures illustrate particular embodiments of the invention.

La figure 2 illustre un affichage de quantième sur rouleau. Comme 31 jours ne sont pas affichables sur la circonférence d'un rouleau de 5mm de diamètre, ou similaire, les unités et les dizaines sont réparties sur deux rouleaux : quatre chiffres sur un rouleau des dizaines 12, dix chiffres sur un rouleau des unités 13.The figure 2 illustrates a date display on a roll. Since 31 days can not be displayed on the circumference of a roll of 5mm in diameter, or similar, the units and tens are spread over two rolls: four digits on a roll of tens 12, ten digits on a roll of units 13 .

L'entraînement des deux rouleaux se fait par deux roues de commande 3120 et 3130, de 31 dents chacune, où des dents sont supprimées, en correspondance des jours où aucune rotation du rouleau respectif n'est nécessaire.The two rollers are driven by two control wheels 3120 and 3130 of 31 teeth each, where teeth are removed, in correspondence of the days when no rotation of the respective roller is necessary.

La figure 3 montre le rouage d'entraînement du rouleau des dizaines 12 : les premiers moyens d'entraînement 31 comportent une première roue de commande 3120, qui comporte seulement quatre dents présentes sur les 31 dents théoriques, pour entraîner les quatre dents d'une étoile à quatre dents 312 d'entraînement du rouleau des dizaines 12. Un sautoir non représenté sur le dessin est nécessaire pour maintenir la position de l'étoile à quatre dents 312, et finir la fonction d'entraînement.The figure 3 shows the drive train of the dozens roll 12: the first drive means 31 comprise a first control wheel 3120, which has only four teeth present on the 31 theoretical teeth, to drive the four teeth of a four-star 312 dozens roller drive teeth 12. A not shown jumper in the drawing is necessary to maintain the position of the four-tooth star 312, and finish the drive function.

La figure 4 montre le rouage d'entraînement du rouleau des unités 13: les premiers moyens d'entraînement 31 comportent une deuxième roue de commande 3130, qui comporte seulement une partie des 31 dents théoriques, en fonction du type d'affichage réalisé, pour entraîner les dix dents d'un pignon des unités 313 d'entraînement du rouleau des unités 13. La deuxième roue de commande 3130 peut, ainsi comporter ou bien trente dents, ou bien, comme ici, vingt-neuf dents, les deux dents manquantes permettant d'annuler la rotation des unités lors du passage du 31 au 01. Un sautoir non représenté sur le dessin est nécessaire pour maintenir la position du pignon des unités 313 à dix dents, et pour maintenir la position d'affichage.The figure 4 shows the drive train of the roll of the units 13: the first drive means 31 comprise a second control wheel 3130, which comprises only a part of the 31 theoretical teeth, depending on the type of display made, to train the ten The second control wheel 3130 may thus have either thirty teeth or, as here, twenty-nine teeth, the two missing teeth enabling the teeth of a gear wheel 313 for driving the roller of the units 13. cancel the rotation of the units during the passage from 31 to 01. A jumper not shown in the drawing is necessary to maintain the gear position of the units 313 to ten teeth, and to maintain the display position.

Ces principes d'entraînement sont semblables à ceux, bien connus, des affichages de quantième à grand guichets.These training principles are similar to the well-known, large-date calendar displays.

Les figures 5 et 6 illustrent l'affichage des unités sur un rouleau des unités 13. Les dix unités réparties sur la circonférence d'un rouleau de diamètre 5mm ne permettent pas une dimension de caractères assez grande. Aussi le rouleau des unités 13, selon l'invention, comporte plusieurs volets 20A, 20B, 20C, 20D, 20E, portant chacun sur ses au moins deux faces opposées 201, 202, au moins deux chiffres des unités. Dans cet exemple, le rouleau des unités 13 est ainsi divisé, et cinq volets 20 à deux faces portent les dix unités. Ces volets 20 présentent alternativement leurs deux faces 201 et 202 à l'utilisateur, et permettent de doubler la hauteur des caractères des unités.The Figures 5 and 6 illustrate the display of units on a roll of units 13. The ten units distributed around the circumference of a 5mm diameter roll do not allow a large enough character size. Also the roll of units 13, according to the invention, comprises several flaps 20A, 20B, 20C, 20D, 20E, each carrying on its at least two opposite faces 201, 202, at least two numbers of the units. In this example, the roll of the units 13 is thus divided, and five flaps 20 with two faces carry the ten units. These flaps 20 have alternately their two faces 201 and 202 to the user, and allow to double the height of the characters of the units.

Les figures 7 à 11 illustrent la rotation et le maintien en place des volets 20 lors de la rotation du rouleau porteur 10, et de leur rotation propre.The Figures 7 to 11 illustrate the rotation and the holding in place of the flaps 20 during the rotation of the carrier roller 10, and their own rotation.

Les volets 20 peuvent être entraînés en rotation continue relativement à la rotation du rouleau 10, avec un rapport de un demi. Cette solution est simple mais demande de la place sur toute la circonférence du rouleau 10, ce qui n'est pas toujours possible.The flaps 20 can be rotated continuously relative to the rotation of the roller 10, with a ratio of one half. This solution is simple but requires space on the entire circumference of the roll 10, which is not always possible.

Pour limiter l'encombrement du système, il est avantageux d'utiliser la solution décrite ci-après, qui gère une rotation d'un volet 20 en un seul point de la circonférence du rouleau 10. Chaque volet 20 est alors maintenu en position par un sautoir 17, qui collabore avec une came de volet 25, notamment de type came-coeur, à deux positions, montée sur l'axe du volet concerné, dont le point bas 26 coopère avec un saillant du sautoir 17. Un ressort 15, notamment comme sur la figure 7 un ressort à bras multiple, applique un effort sur le sautoir 17 qui maintien la position du volet 20. Un pignon 35 est également monté sur l'axe du volet 20.To limit the bulk of the system, it is advantageous to use the solution described below, which manages a rotation of a flap 20 at a single point of the circumference of the roll 10. Each flap 20 is then held in position by a jumper 17, which collaborates with a shutter cam 25, in particular of the cam-core type, with two positions, mounted on the axis of the flap concerned, the low point 26 of which cooperates with a protrusion of the jumper 17. A spring 15, especially as on the figure 7 a spring with multiple arms, applies a force on the jumper 17 which maintains the position of the flap 20. A pinion 35 is also mounted on the axis of the flap 20.

Ce pignon 35 peut être entraîné par un rouage que comportent les deuxièmes moyens d'entraînement 32, non illustré sur les figures. Dans la variante particulière de la figure 7, les deuxièmes moyens d'entraînement 32 comportent un segment de denture fixe, situé en un point de la périphérie du rouleau 10. Lors de la rotation du rouleau 10, un pignon de volet 35 vient en contact de coopération avec ce segment, ce qui engendre une rotation de 180° du volet 20 concerné.This pinion 35 can be driven by a gear that includes the second drive means 32, not shown in the figures. In the particular variant of the figure 7 the second drive means 32 comprise a stationary tooth segment located at a point on the periphery of the roller 10. On rotation of the roller 10, a flap gear 35 comes into cooperative contact with this segment, which generates a 180 ° rotation of the flap 20 concerned.

Les figures 12 à 14 illustrent, de façon similaire, la rotation d'un rouleau de mois comportant six volets 20. Naturellement, pour réaliser douze indications sur la circonférence, on peut aussi utiliser quatre volets à trois faces, voire trois volets à quatre faces.The Figures 12 to 14 similarly illustrate the rotation of a roll of months having six flaps 20. Of course, to make twelve indications on the circumference, it is also possible to use four flaps with three faces, or even three flaps with four faces.

La figure 15 illustre la rotation d'un rouleau des unités à cinq volets. Comme exposé plus haut, la rotation d'un rouleau des unités peut se faire avec une roue de 31 dont il manque une ou deux dents pour le passage sur un pignon de dix dents. Pour une rotation de 1/5 de tour par jour, pour un rouleau avec cinq volets, le pignon de dix dents devrait être réduit à cinq dents, géométriquement cette réduction n'est pas possible avec la fonction. Il est donc nécessaire de rajouter une réduction par engrenage avec un couple de réduction : 3132, 3133, correspondant à la réduction voulue. Dans cet exemple, les différentes roues du rouage effectuent:

  • 3130 de 31 dents :1 tour par mois
  • 3132 de 10 dents :1 tour par 10 jours
  • 3133 de 20 dents :1 tour par 10 jours
  • 313 de 10 dents : 1 tour par 5 jours
The figure 15 illustrates the rotation of a roll of five-part units. As explained above, the rotation of a roll of the units can be done with a wheel 31 which lacks one or two teeth for the passage on a pinion of ten teeth. For a rotation of 1/5 turn per day, for a roll with five flaps, the pinion of ten teeth should be reduced to five teeth, geometrically this reduction is not possible with the function. It is therefore necessary to add a gear reduction with a reduction torque: 3132, 3133, corresponding to the desired reduction. In this example, the different wheels of the train perform:
  • 3130 of 31 teeth: 1 turn per month
  • 3132 of 10 teeth: 1 turn per 10 days
  • 3133 of 20 teeth: 1 turn per 10 days
  • 313 of 10 teeth: 1 turn per 5 days

Dans un mode de réalisation particulier à croix de Malte, les premiers moyens d'entraînement 31 comportent un rouage d'entrée 61 qui entraîne une roue principale 60 dont une révolution correspond à la période temporelle d'affichage du rouleau 10, 11, 12, 13, 14, et qui porte une came principale 50 porteuse de secteurs périphériques de géométrie inégale, des secteurs concentriques 51 correspondant aux positions fixes d'affichage, et des secteurs avec évidements 52 et munis de goupilles d'entraînement 5X correspondant aux positions mobiles du rouleau d'affichage10, 11, 12, 13, 14. Cette came principale 50 coopère avec une came secondaire 40 en croix de Malte excentrée, pivotant autour d'un point fixe, et agencée pour pivoter lors du passage d'un évidement 52 et d'une goupille 5X. Cette came secondaire 40 porte une roue secondaire 42 engrenant avec une roue d'entraînement de rouleau 62, et la roue principale 60 porte encore une roue principale d'entraînement de volet 63, laquelle engrène elle-même avec un pignon de volet 64 agencé pour commander un pignon d'entraînement de volet 35 axé sur l'axe de volet D20 ou constituant lui-même un pignon d'entraînement de volet 35.In a particular Maltese cross embodiment, the first drive means 31 comprise an input gear train 61 which drives a main wheel 60, one revolution of which corresponds to the display time period of the roller 10, 11, 12, 13, 14, and which carries a main cam 50 carrying peripheral sectors of unequal geometry, concentric sectors 51 corresponding to fixed display positions, and sectors with recesses 52 and provided with 5X drive pins corresponding to the moving positions of the display roller 10, 11, 12, 13, 14. This main cam 50 cooperates with a secondary eccentric Maltese cross cam 40, pivoting about a fixed point, and arranged to pivot during the passage of a recess 52 and a 5X pin. This secondary cam 40 carries a secondary wheel 42 meshing with a roller drive wheel 62, and the main wheel 60 still carries a shutter drive main wheel 63, which meshes itself with a shutter pinion 64 arranged to controlling a shutter drive gear 35 oriented on the shutter axis D20 or itself constituting a shutter drive gear 35.

Plus particulièrement, la figure 16 illustre une variante particulière cette réalisation à croix de Malte, pour la commande de rotation d'un rouleau à sept indications, correspondant aux jours de la semaine. Dans ce cas des jours de la semaine, le nombre de jours étant un nombre premier, il n'est pas possible de le répartir sur des volets aussi simplement que précédemment. Si le rouleau ne permet pas d'afficher les sept jours sur la circonférence, les solutions sont limitées:

  • rouleau avec six positions fixes et un volet à deux faces ;
  • rouleau avec cinq positions fixes et deux volets à deux faces ;
  • rouleau avec quatre positions fixes et trois volets à deux faces ;
  • rouleau avec une position fixe et deux volets à trois faces ;
In particular, the figure 16 illustrates a particular variant that embodiment of the Maltese cross, for the rotation control of a roller with seven indications, corresponding to the days of the week. In this case days of the week, the number of days being a prime number, it is not possible to distribute it on flaps as simply as before. If the roll does not display the seven days on the circumference, the solutions are limited:
  • roll with six fixed positions and a two-sided flap;
  • roll with five fixed positions and two flaps with two faces;
  • roll with four fixed positions and three flaps with two faces;
  • roller with a fixed position and two flaps with three faces;

La figure 16 décrit la première variante d'un rouleau avec six positions fixes et un volet à deux faces. L'adaptation aux autres variantes peut être réalisée de façon similaire. Les premiers moyens d'entraînement 31 comportent un rouage d'entrée 61, qui entraîne une roue principale 60 dont une révolution correspond à la période temporelle d'affichage du rouleau 10, dans l'application à l'affichage des jours de la semaine, cette roue principale 60 est entraînée de 1/7 de tour par jour.The figure 16 describes the first variant of a roll with six fixed positions and a two-sided flap. The adaptation to the other variants can be carried out in a similar way. The first drive means 31 comprise an input gear train 61, which drives a main wheel 60, one revolution of which corresponds to the display time period of the roll 10, in the application to the display of the days of the week, this main wheel 60 is driven 1/7 turn per day.

Plus généralement, pour un affichage de N périodes, la roue principale 60 est entraînée de 1/N de tour par jour.More generally, for a display of N periods, the main wheel 60 is driven 1 / N of rotation per day.

La roue principale 60 porte une came principale 50, qui est séparée en N secteurs périphériques différents. Ces secteurs périphériques sont de géométrie inégale : des secteurs concentriques 51 correspondent aux positions fixes d'affichage, et des secteurs avec évidements 52 et munis de goupilles d'entraînement 5X correspondent aux positions mobiles du rouleau d'affichage. De plus, l'amplitude angulaire des secteurs concentriques 51 peut être variable, comme on le verra plus loin.The main wheel 60 carries a main cam 50, which is separated into N different peripheral sectors. These peripheral sectors are of unequal geometry: concentric sectors 51 correspond to fixed display positions, and sectors with recesses 52 and provided with drive pins 5X correspond to the mobile positions of the display roller. In addition, the angular amplitude of the concentric sectors 51 may be variable, as will be seen later.

Cette came principale 50 coopère avec une came secondaire 40 en croix de Malte, par les goupilles et les encoches mentionnées ci-dessus. Cette came secondaire 40 est excentrée, pivote autour d'un point fixe, et est agencée pour pivoter lors du passage d'un évidement 52 et d'une goupille 5X.This main cam 50 cooperates with a secondary cam 40 in Maltese cross, by the pins and notches mentioned above. This secondary cam 40 is eccentric, pivots about a fixed point, and is arranged to pivot during the passage of a recess 52 and a pin 5X.

Cette came secondaire 40 porte une roue secondaire 42 qui engrène avec une roue d'entraînement de rouleau 62, elle-même solidaire du rouleau d'affichage 10 concerné.This secondary cam 40 carries a secondary wheel 42 which meshes with a roller drive wheel 62, itself secured to the display roller 10 concerned.

La came secondaire 40 en croix de Malte entraîne ainsi, six jours sur sept, cette roue d'entraînement de rouleau 62 de 1/6 de tour, ce qui correspond aux six positions fixes du rouleau.The secondary cam 40 Maltese cross thus causes, six days out of seven, the wheel drive wheel 62 of 1/6 of a turn, which corresponds to the six fixed positions of the roll.

Le septième jour, la portée 41 de la came secondaire 40 en croix de Malte reste en appui sur le plus long 510 des secteurs concentriques 51, et la came secondaire 40 en croix de Malte ne peut donc pas pivoter. La roue d'entraînement de rouleau 62 n'est pas entraînée, et le rouleau reste alors immobile.On the seventh day, the span 41 of the secondary cam 40 in Maltese cross remains in support on the longest 510 of the concentric sectors 51, and the secondary cam 40 Maltese cross therefore can not rotate. The roller drive wheel 62 is not driven, and the roller then remains stationary.

La roue principale 60 porte encore une roue principale d'entraînement de volet 63, laquelle engrène elle-même avec un pignon de volet 64 agencé pour commander un pignon d'entraînement de volet 35 axé sur l'axe de volet D20, ou bien constituant lui-même un pignon d'entraînement de volet 35.The main wheel 60 further carries a flap drive main wheel 63, which in turn meshes with a flap gear 64 arranged to drive a flap drive gear 35 centered on the flap axis D20, or constituting itself a shutter drive sprocket 35.

Cette roue principale d'entraînement de volet 63 effectue, comme la roue principale 60, 1/7 de tour par jour.This main shutter drive wheel 63 performs, like the main wheel 60, 1/7 turn per day.

Le pignon de volet 64 porte le volet 20 à deux faces, et engrène avec un rapport de 3.5 avec la roue principale d'entraînement de volet 63.The shutter gear 64 carries the two-sided shutter 20 and meshes with a ratio of 3.5 with the shutter drive main wheel 63.

Donc, lorsque la roue d'entraînement de rouleau 62 est immobile, et que la roue principale 60 fait 1/7 de tour, le pignon de volet 64 fait 1/2 tour, avec changement de côté du volet 20.Thus, when the roller drive wheel 62 is stationary, and the main wheel 60 is 1/7 turn, the shutter gear 64 is 1/2 turn, with side change of the shutter 20.

Lorsque la roue d'entraînement de rouleau 62 est libérée et fait 1/6 de tour et que la roue principale 60 fait 1/7 de tour, le pignon de volet 64 fait 1/12 de tour, donc en six jours reprendra sa place de départ.When the roller drive wheel 62 is released and is 1/6 turn and the main wheel 60 is 1/7 turn, the shutter gear 64 is 1/12 turn, so in six days will resume its place departure.

Les figures 17 et 18 illustrent une variante avantageuse de l'invention, où les sautoirs et le ressort assurant le maintien en position des volets sont remplacés par des aimants 70, qui exercent un effort, notamment d'attraction, sur les cames en matériau magnétique.The Figures 17 and 18 illustrate an advantageous variant of the invention, wherein the jumpers and the spring ensuring the holding in position of the flaps are replaced by magnets 70, which exert a force, in particular attraction, on the cams of magnetic material.

Dans un autre mode de réalisation particulier à dentures partielles, en lieu et place des systèmes à croix de Malte décrits ci-dessus, les premiers moyens d'entraînement 31 comportent un rouage d'entrée 61 qui entraîne une roue principale 60 dont une révolution correspond à la période temporelle d'affichage du rouleau 10, 11, 12, 13, 14, et qui porte une came principale 50 porteuse de secteurs périphériques de géométrie inégale: des secteurs concentriques 51 correspondant aux positions fixes d'affichage, et des secteurs comportant des moyens d'entraînement 53 voisins d'évidements 52. La came principale 50 coopère avec une étoile 71 excentrée, pivotant autour d'un point fixe, et agencée pour pivoter lors du passage d'un tel moyen d'entraînement 53, et pour rester dans sa position angulaire quand deux dents 72 qu'elle comporte sont en appui sur un secteur concentrique 51. Cette étoile 71 porte une roue secondaire 70, qui engrène avec une roue d'entraînement de rouleau 62 elle-même solidaire du rouleau 10, 11, 12, 13, 14. La roue principale 60 porte, comme précédemment, une roue principale d'entraînement de volet 63, laquelle engrène elle-même avec un pignon de volet agencé pour commander un pignon d'entraînement de volet 35 axé sur l'axe de volet D20 ou constituant lui-même un pignon d'entraînement de volet 35.In another particular embodiment with partial teeth, instead of the Maltese cross systems described above, the first drive means 31 comprise an input gear train 61 which drives a main wheel 60, a revolution corresponding to at the time of display of the roller 10, 11, 12, 13, 14, and which carries a main cam 50 carrying peripheral sectors of unequal geometry: concentric sectors 51 corresponding to the fixed display positions, and sectors comprising driving means 53 adjacent recesses 52. The main cam 50 cooperates with an off-center star 71, pivoting about a fixed point, and arranged to pivot during the passage of such a drive means 53, and for remain in its angular position when two teeth 72 that it comprises are supported on a concentric sector 51. This star 71 carries a secondary wheel 70, which meshes with a drive wheel r oreleau 62 itself secured to the roller 10, 11, 12, 13, 14. The main wheel 60 carries, as previously, a main impeller drive wheel 63, which meshes itself with a shutter pinion arranged to control a flap drive gear 35 oriented on the flap axis D20 or itself constituting a flap drive gear 35.

Plus particulièrement, les figures 19 et 20 illustrent une variante de ce mode de réalisation, qui comporte des dentures partielles. Cette variante est illustrée pour un cas particulier non limitatif d'une version à cinq positions fixes, comportant deux volets mobiles 20B et 20E à deux faces, et sans croix de Malte.In particular, Figures 19 and 20 illustrate a variant of this embodiment, which has partial teeth. This variant is illustrated for a particular non-limiting case of a version with five fixed positions, comprising two movable flaps 20B and 20E with two faces, and without Maltese crosses.

Un pignon entraîneur du rouage d'entrée 61 non représenté effectue 1 tour par jour, et entraîne une roue principale 60, qui fait 1/N, soit ici 1/7 tour par jour.A drive gear of the input train 61 not shown performs 1 revolution per day, and drives a main wheel 60, which is 1 / N, here 1/7 turn per day.

La roue principale 60 porte une came principale 50, qui est séparée en sept secteurs périphériques différents, les secteurs périphériques comportant ou non des moyens d'entraînement (ici constitués par des dents 53), les secteurs concentriques 51 correspondant aux positions fixes d'affichage du rouleau 20, et les secteurs avec moyens d'entraînement 53 correspondant aux positions mobiles du rouleau d'affichage.The main wheel 60 carries a main cam 50, which is separated into seven different peripheral sectors, the peripheral sectors with or without drive means (here constituted by teeth 53), the concentric sectors 51 corresponding to the fixed display positions of the roll 20, and the sectors with drive means 53 corresponding to the movable positions of the display roll.

Cette came principale 50 coopère avec une étoile 71 de 4 dents, maintenue par un sautoir non représenté. Cette étoile de quatre 71 est excentrée, pivote autour d'un point fixe, elle est agencée pour pivoter lors du passage d'un moyen d'entraînement, notamment d'une dent dans la réalisation illustrée, non limitative.This main cam 50 cooperates with a star 71 of 4 teeth, held by a not shown jumper. This star of four is eccentric, pivots about a fixed point, it is arranged to pivot during the passage of a drive means, in particular a tooth in the illustrated embodiment, not limiting.

Les moyens d'entraînement 53 comportant ici des dents, et de préférence combinés à des évidements 52, sont agencés pour engrener avec des dents 72 de l'étoile de quatre 71. Par contre, quand deux dents 72 successives de l'étoile de quatre 71 sont simultanément en appui sur un secteur concentrique 51, l'étoile de quatre 71 ne peut pas tourner.The drive means 53 comprising teeth here, and preferably combined with recesses 52, are arranged to mesh with teeth 72 of the star of four 71. On the other hand, when two successive teeth 72 of the star of four 71 are simultaneously supported on a concentric sector 51, the star of four 71 can not rotate.

L'étoile de quatre 71, pivotée sur la platine, est ainsi agencée pour effectuer 1/4 de tour par jour, sauf deux jours par semaine. Dans l'exemple illustré, quand cette étoile 71 a pivoté du lundi au mardi, elle reste dans sa position le mardi et le mercredi, avant de changer de position entre le mercredi et le jeudi. De la même façon, quand l'étoile 71 a pivoté du vendredi au samedi, elle reste dans sa position le samedi et le dimanche, avant de changer de position entre le dimanche et le lundi. Le volet 20B affichera une première position le mardi, pivotera de 180° du mardi au mercredi, pour afficher une deuxième position le mercredi. De la même façon, le volet 20E affichera une première position le samedi, pivotera de 180° du samedi au dimanche, pour afficher une deuxième position le dimanche. Les autres jours, l'utilisateur verra des affichages fixes en périphérie du rouleau 20 : 20A le lundi, 20C le jeudi, 20D le vendredi.The star of four 71, pivoted on the plate, is thus arranged to perform 1/4 turn per day, except two days per week. In the illustrated example, when this star 71 has rotated from Monday to Tuesday, it remains in its position on Tuesday and Wednesday, before changing positions between Wednesday and Thursday. In the same way, when star 71 has rotated from Friday to Saturday, it stays in its position on Saturday and Sunday, before changing positions between Sunday and Monday. Strand 20B will show a first position on Tuesday, turning 180 ° from Tuesday to Wednesday, to post a second position on Wednesday. In the same way, the 20E component will show a first position on Saturday, pivoting 180 ° from Saturday to Sunday, to post a second position on Sunday. On other days, the user will see fixed displays around the 20: 20A roll on Monday, 20C on Thursday, 20D on Friday.

Cette étoile de quatre 71 porte une roue secondaire 70, qui engrène avec une roue d'entraînement de rouleau 62, elle-même solidaire du rouleau d'affichage 10.This four star 71 carries a secondary wheel 70, which meshes with a roller drive wheel 62, itself secured to the display roller 10.

L'étoile de quatre dents 71 entraîne de fait, cinq jours sur sept, cette roue d'entraînement de rouleau 62 de 1/5 de tour, ce qui correspond aux cinq positions fixes du rouleau.The star of four teeth 71 in fact drives, five days out of seven, this wheel drive wheel 62 of 1/5 of a turn, which corresponds to the five fixed positions of the roller.

Les deux jours supplémentaires, l'étoile de quatre 71 reste en appui sur les secteurs concentriques 51, et ne peut donc pas pivoter. La roue d'entraînement de rouleau 62 n'est pas entraînée, et le rouleau 10 reste alors immobile.The two additional days, the star of four 71 remains in support on the concentric sectors 51, and can not rotate. The roller drive wheel 62 is not driven, and the roller 10 then remains stationary.

La roue principale 60 porte encore une roue principale d'entraînement de volet 63, laquelle engrène elle-même avec un pignon de volet agencé pour commander un pignon d'entraînement de volet axé sur l'axe de volet D20, ou bien constituant lui-même un pignon d'entraînement de volet 35.The main wheel 60 again carries a flap drive main wheel 63, which itself meshes with a shutter gear arranged to drive a flap drive gear centered on the flap axis D20, or itself constituting it. even a shutter drive gear 35.

Cette roue principale d'entraînement de volet 63 effectue, comme la roue principale, 1/7 de tour par jour.This main shutter drive wheel 63 performs, like the main wheel, 1/7 turn per day.

Les pignons de volets portent les volets 20B et 20E à deux faces, et engrènent avec un rapport de 3.5 avec la roue principale d'entraînement de volet 63.The flap gables have the two-sided flaps 20B and 20E, and mesh with a ratio of 3.5 with the flap drive main wheel 63.

Donc, lorsque la roue d'entraînement de rouleau 62 est immobile, et que la roue principale 60 fait 1/7 de tour, le pignon de volet fait 1/2 tour, avec changement de côté du volet 20 concerné.Thus, when the roller drive wheel 62 is stationary, and the main wheel 60 is 1/7 turn, the shutter gear is 1/2 turn, with side change of the flap 20 concerned.

Lorsque la roue d'entraînement de rouleau 62 est libérée et fait 1/5 de tour et que la roue principale 60 fait 1/7 de tour, le pignon de volet fait 1/10 de tour, donc en 5 jours reprendra sa place de départ.When the roller drive wheel 62 is released and is 1/5 turn and the main wheel 60 is 1/7 turn, the shutter gear is 1/10 turn, so in 5 days will resume its place of departure.

Les figures 22 à 26 représentent, de façon schématisée, une variante pour un affichage des années bissextiles 400. Cet affichage des années bissextiles 400 peut se faire par une ou plusieurs aiguilles, notamment et non limitativement dans l'exemple des figures avec une aiguille triple 401 à 120°, dans le prolongement de l'axe 402 du rouleau des mois, face à un affichage complémentaire bissextile 403, notamment comportant de façon usuelle des repères tels que 1, 2, 3, L, ou B, ou similaire. Une étoile 404, maintenue par un sautoir 405, entraîne cette aiguille triple 401, et est elle-même entraînée par un levier excentré 406 solidaire d'un volet 407. Dans l'exemple illustré, la rotation de l'étoile 404 se fait par un levier excentré 406 solidaire du volet 407 des mois de mars/septembre. Lorsque ce volet 407 pivote par l'intermédiaire du secteur denté 408, celui-ci pousse d'un cran l'étoile 404, tel que visible saur les figures 24 et 25. Le rouleau fait un tour en six mois, au mois de juillet le levier ne déclenche pas la rotation de l'étoile.The Figures 22 to 26 schematically represent a variant for a leap year display 400. This display leap years 400 can be done by one or more needles, including and not limited to the example of the figures with a triple needle 401 to 120 °, in the extension of the axis 402 of the roll of months, in front of a leap-supplementary display 403, in particular conventionally comprising markers such as 1, 2, 3, L, or B, or the like. A star 404, held by a jumper 405, drives this triple needle 401, and is itself driven by an eccentric lever 406 integral with a flap 407. In the illustrated example, the rotation of the star 404 is made by an eccentric lever 406 secured to the shutter 407 of the months of March / September. When this flap 407 pivots through the toothed sector 408, the latter pushes the star 404 one notch, as can be seen by the Figures 24 and 25 . The roller makes a turn in six months, in July the lever does not trigger the rotation of the star.

La figure 27 illustre une autre variante de maintien des volets 407 sans sautoir, et avec entraînement par une denture partielle, avec un guidage par une circonférence extérieure 420 en contact avec le volet 407 lui-même. Notamment, tel que visible sur la figure 27, le volet 407 est guidé en position par deux dents 410, 411, de son pignon d'entraînement 409. Celui-ci peut avoir une ou plusieurs dents supprimées, au niveau d'un évidement 412, pour faciliter la fonction. L'appui se fait avantageusement sur une circonférence de guidage partielle extérieure ou intérieure, par deux dents délimitant une circonférence de rotation croisant la circonférence de guidage. Ce croisement limite la rotation des rouleaux sur leurs axes. La circonférence de guidage est interrompue sur une portion 421 permettant la rotation. Cette rotation est pilotée par un segment de denture 408 prévu à cet effet. Celui-ci peut comme sur la figure, faire partie de la circonférence de guidage 420.The figure 27 illustrates another variant of maintaining the flaps 407 without jumper, and driven by a partial toothing, with a guide by an outer circumference 420 in contact with the flap 407 itself. In particular, as visible on the figure 27 , the flap 407 is guided in position by two teeth 410, 411, of its drive pinion 409. This can have one or more teeth removed, at a recess 412, to facilitate the function. The support is advantageously on an outer or inner partial guide circumference, by two teeth delimiting a circumference of rotation intersecting the guiding circumference. This crossing limits the rotation of the rollers on their axes. The guiding circumference is interrupted on a portion 421 allowing rotation. This rotation is controlled by a gear segment 408 provided for this purpose. This can, as in the figure, be part of the guiding circumference 420.

De la même manière, dans une variante de volet sans sautoir, le volet peut être guidé directement par une circonférence extérieure en contact avec le volet lui-même. De cette façon, la circonférence de guidage est interrompue pour laisser passer le volet. Le pignon d'entraînement peut alors se retrouver dans la configuration de la variante des figures 7 à 11, ou encore dans celle des figures 17 et 18.In the same manner, in a variant of flap without jumper, the flap can be guided directly by an outer circumference in contact with the flap itself. In this way, the guide circumference is interrupted to let the flap. The drive pinion can then be found in the configuration of the variant of the Figures 7 to 11 , or in that of Figures 17 and 18 .

Les différentes variantes de l'invention permettent de réaliser des affichages à rouleaux de toutes sortes d'indications dans le volume réduit d'une montre de dimension normale, avec notamment une épaisseur totale de l'ordre de 10 mm à l'extérieur des glaces, ou de la glace et du fond. Les volets ne sont en contact avec aucune partie de la montre, et ne sont soumis à aucun choc ou frottement dans le cadre de leur fonctionnement normal.The different variants of the invention make it possible to produce roller displays of all kinds of indications in the reduced volume of a watch of normal size, with in particular a total thickness of the order of 10 mm outside the windows. , or ice and bottom. The flaps are not in contact with any part of the watch, and are not subjected to any shock or friction as part of their normal operation.
