Description détaillée de l'inventionDetailed description of the invention

La présente invention permet de déconnecter un rouage de finissage d'un rouage d'affichage, par exemple et de maintenir en place l'un des deux et de préférence le rouage d'affichage.The present invention makes it possible to disconnect a finishing gear from a display gear, for example and to hold one of the two and preferably the display gear in place.

Ainsi, il peut être possible de déconnecter le train d'engrenage du rouage de finissage et le train d'engrenage du rouage d'affichage et de pouvoir générer une friction dans le rouage d'affichage lors du débrayage pour le maintenir en place notamment.Thus, it may be possible to disconnect the gear train from the finishing gear train and the gear train from the display gear train and to be able to generate friction in the display gear during disengagement in order to hold it in place in particular.

Ce débrayage peut être actionné soit par l'intermédiaire du premier mécanisme, soit par un mécanisme interne au mouvement lors du passage d'une fonction.This disengagement can be actuated either by means of the first mechanism, or by a mechanism internal to the movement when a function passes.

La présente invention, illustrée sur la figure 1, se présente sous la forme d'un rouage d'horlogerie 100 configuré pour débrayer un train d'engrenage. Ce rouage d'horlogerie 100 se compose d'un ensemble d'engrenage 110, d'un organe de débrayage 120, d'un organe de maintien 121 et d'un organe de commande 130.The present invention, illustrated in figure 1 , is in the form of a clockwork gear 100 configured to disengage a gear train. This clockwork train 100 consists of a gear assembly 110, a clutch member 120, a holding member 121 and a control member 130.

Comme cela est observable sur la figure 1 et 2, l'ensemble d'engrenage 110 comprend un premier mobile 111 qui peut être une première roue 111 ou un premier mobile 111 comprenant un premier pignon 116, un deuxième mobile 112 qui peut être une deuxième roue 112 ou comprenant au moins un deuxième pignon, et un mobile intermédiaire 113.As can be seen on the figure 1 and 2 , the gear assembly 110 comprises a first mobile 111 which may be a first wheel 111 or a first mobile 111 comprising a first pinion 116, a second mobile 112 which may be a second wheel 112 or comprising at least a second pinion, and an intermediate mobile 113.

Ce mobile intermédiaire 113 peut être disposé entre le premier mobile 111 et le deuxième mobile 112. Selon les modes de réalisation, le mobile intermédiaire 113 peut être disposé entre la première roue 111 et la deuxième roue 112 ou le deuxième pignon ou entre la deuxième roue 112 et la première roue 111 ou le premier pignon 116.This intermediate mobile 113 can be placed between the first mobile 111 and the second mobile 112. According to the embodiments, the intermediate mobile 113 can be placed between the first wheel 111 and the second wheel 112 or the second pinion or between the second wheel 112 and the first wheel 111 or the first pinion 116.

Dans ces configurations, le mobile intermédiaire 113 peut être entraîné par ou peut entraîner le premier mobile 111 et/ou ledit deuxième mobile 112 et par extension, la première roue 111 ou le premier pignon 116, et/ou la deuxième roue 112 ou le deuxième pignon selon les modes de réalisation, de sorte à transmettre le mouvement au mobile intermédiaire 113 et préférence le mouvement rotatif au mobile intermédiaire 113. En effet, comme cela est observable sur les figures 1 et 2, le premier mobile 111 et/ou le deuxième mobile 112 peut être une roue du rouage de finissage ou une roue d'affichage, et le mobile intermédiaire 113 peut être une roue de renvoi en contact avec la roue du rouage de finissage et la roue d'affichage ou avec leurs pignons respectifs.In these configurations, the intermediate mobile 113 can be driven by or can drive the first mobile 111 and / or said second mobile 112 and by extension, the first wheel 111 or the first pinion 116, and / or the second wheel 112 or the second pinion according to the embodiments, so as to transmit the movement to the intermediate mobile 113 and preferably the rotary movement to the intermediate mobile 113. Indeed, as can be observed on the figures 1 and 2 , the first mobile 111 and / or the second mobile 112 can be a wheel of the finishing gear or a display wheel, and the intermediate mobile 113 can be a return wheel in contact with the wheel of the finishing gear and the wheel display or with their respective gears.

À cela s'ajoute un organe de débrayage 120 configuré pour déplacer le mobile intermédiaire 113 dans un plan de déplacement entre une position d'embrayage 101, comme le montre un mode de réalisation représenté sur la figure 1, dans laquelle ledit premier mobile 111, ledit mobile intermédiaire 113 et ledit deuxième mobile 112 sont reliés cinématiquement et une position de débrayage 102, comme cela est représenté sur la figure 2, dans laquelle ledit mobile intermédiaire 113 est dégrené du deuxième mobile 112, par exemple. Ainsi, le mobile intermédiaire peut être en mouvement et au contact du premier mobile 111 tout en étant débrayé du deuxième mobile 112, ou vice versa, ce qui permet lors de l'embrayage, c'est-à-dire lors de la remise en contact du mobile intermédiaire 113 avec le premier mobile 111 ou le deuxième mobile 112 d'éviter un contact dent contre dent car le mobile intermédiaire continue à être en mouvement et donc diminue les risques de dommage des mobiles.To this is added a disengagement member 120 configured to move the intermediate mobile 113 in a displacement plane between a clutch position 101, as shown in an embodiment shown in FIG. figure 1 , wherein said first mobile 111, said intermediate mobile 113 and said second mobile 112 are kinematically connected and a disengaged position 102, as shown in figure figure 2 , wherein said intermediate mobile 113 is unhinged from the second mobile 112, for example. Thus, the intermediate mobile can be in motion and in contact with the first mobile 111 while being disengaged from the second mobile 112, or vice versa, which allows during engagement, that is to say when resetting. contact of the intermediate mobile 113 with the first mobile 111 or the second mobile 112 to avoid tooth-to-tooth contact because the intermediate mobile continues to be in motion and therefore reduces the risk of damage to the mobile.

Comme mentionné précédemment, ce rouage d'horlogerie 100 comprend également un organe de maintien 121 pour maintenir le premier mobile 111 et/ou le deuxième mobile 112, et plus particulièrement, l'organe de débrayage 120 peut comprendre l'organe de maintien 121.
En d'autres termes, l'organe de maintien 121 sert de frein 121 ou à freiner le premier mobile 111 et/ou le deuxième mobile 112, selon les modes de réalisation. Le premier mobile 111 et/ou le deuxième mobile 112 peut ou peuvent comprendre une surface de friction 118 et de préférence une denture et/ou une surface périphérique. Cette surface de friction 118 est configuré pour coopérer avec l'organe de maintien 121.As mentioned previously, this clockwork gear 100 also includes a holding member 121 to hold the first mobile 111 and / or the second mobile 112, and more particularly, the disengaging member 120 may include the holding member 121.
In other words, the holding member 121 serves as a brake 121 or to brake the first mobile 111 and / or the second mobile 112, depending on the embodiments. The first mobile 111 and / or the second mobile 112 may or may include a friction surface 118 and preferably a set of teeth and / or a peripheral surface. This friction surface 118 is configured to cooperate with the holding member 121.

Ce frein 121, ou comme mentionné précédemment, cet organe de maintien 121 peut être déplacé par un organe de commande 130 au contact du premier mobile 111 et/ou du deuxième mobile 112 et sert à maintenir le premier mobile 111 et/ou le deuxième mobile 112 en position, c'est-à-dire immobile, lorsque l'organe de débrayage 120 est en position de débrayage 102.This brake 121, or as mentioned previously, this holding member 121 can be moved by a control member 130 in contact with the first mobile 111 and / or the second mobile 112 and serves to hold the first mobile 111 and / or the second mobile 112 in position, that is to say stationary, when the disengaging member 120 is in the disengaging position 102.

Ce même organe de commande 130 peut également déplacer l'organe de débrayage 120 entre la position d'embrayage 101 et la position de débrayage 102, par l'intermédiaire d'un bras d'actionnement 125.This same control member 130 can also move the disengaging member 120 between the clutch position 101 and the disengaged position 102, by means of an actuating arm 125.

En effet, l'organe de débrayage 120 comprend un bras d'actionnement 125 par lequel l'organe de commande 130 déplace l'organe de débrayage 120 entre la position d'embrayage 101 et la position de débrayage 102 de sorte à actionner l'organe de débrayage 120 tout en étant distant de l'organe de commande 130. En d'autres termes l'organe de commande 130 peut se trouver à la périphérie de la platine (non représentée) et l'organe de débrayage 120 plus au centre ou de l'autre côté de la platine.Indeed, the disengaging member 120 comprises an actuating arm 125 by which the control member 130 moves the disengaging member 120 between the clutch position 101 and the disengaged position 102 so as to actuate the clutch. disengagement member 120 while being remote from the control member 130. In other words, the control member 130 may be located at the periphery of the plate (not shown) and the disengagement member 120 more in the center or on the other side of the turntable.

Ainsi, il est possible de maintenir en position le rouage d'horlogerie tout en débrayant le mécanisme de sorte à permettre la mise à l'heure par exemple.Thus, it is possible to keep the clockwork wheel in position while disengaging the mechanism so as to allow time setting, for example.

Par ailleurs, l'organe de commande 130 comprend un plot 135 et peut se déplacer entre une première position 131 et une deuxième position 132, comme cela est visible sur les figures. Ce plot 135 est configuré pour être en butée et déplacer le bras d'actionnement 125 de sorte à déplacer l'organe de débrayage 120 de la position d'embrayage 101 vers la position de débrayage 102 lorsque ledit plot 135 se déplace de la première position 131 vers la deuxième position 132.Furthermore, the control member 130 comprises a stud 135 and can move between a first position 131 and a second position 132, as can be seen in the figures. This stud 135 is configured to be in abutment and move the actuating arm 125 so as to move the disengaging member 120 from the clutch position 101 to the disengaged position 102 when said pin 135 moves from the first position. 131 to the second position 132.

Comme cela est visible sur les figures 1 et 2, l'organe de débrayage 120 peut comprendre un premier bras flexible 122 pouvant relier l'organe de maintien 121 à l'organe de débrayage 120. Plus exactement, le premier bras flexible 122 est configuré pour déplacer l'organe de maintien 121 au contact du premier mobile 111 et/ou du deuxième mobile 112 de sorte à amener la surface de maintien 124 au contact du premier mobile 111 et/ou du deuxième mobile 112. Selon les modes de réalisation, l'organe de maintien 121 peut être tangent avec et/ou peut épouser la forme de la surface de friction 118 et de préférence de la denture et/ou de la surface périphérique du premier mobile 111 et/ou du deuxième mobile 112 de sorte que le contact entre la surface de friction 118 et l'organe de maintien 121 est soit ponctuel, soit linéaire ou surfacique. Dans le mode de réalisation des figures 1 et 2, c'est le deuxième mobile qui comprend la surface de friction 118.As can be seen on the figures 1 and 2 , the disengaging member 120 may include a first flexible arm 122 which can connect the retaining member 121 to the disengaging member 120. More exactly, the first flexible arm 122 is configured to move the retaining member 121 in contact. of the first mobile 111 and / or of the second mobile 112 so as to bring the retaining surface 124 into contact with the first mobile 111 and / or of the second mobile 112. According to the embodiments, the retaining member 121 can be tangent with and / or can match the shape of the friction surface 118 and preferably of the toothing and / or of the peripheral surface of the first mobile 111 and / or of the second mobile 112 so that the contact between the friction surface 118 and the 'holding member 121 is either punctual, linear or surface. In the embodiment of figures 1 and 2 , it is the second mobile which comprises the friction surface 118.

Ce premier bras flexible 122 peut faire sailli en porte-à-faux à l'organe de débrayage 120 et peut comporter l'organe de maintien 121. Le premier bras flexible 122 peut être un organe de rappel configuré pour rappeler en position l'organe de maintien 121 à la manière d'un ressort ou se déformer élastiquement selon le mode de réalisation.This first flexible arm 122 can project in a cantilever manner from the disengaging member 120 and may include the holding member 121. The first flexible arm 122 can be a return member configured to return the member to position. support 121 in the manner of a spring or deform elastically according to the embodiment.

Toujours sur les figures, l'organe de débrayage 120 est muni d'une surface de maintien 124, et plus particulièrement l'organe de maintien 121 comprend la surface de maintien 124. Cette surface de maintien 124 peut coopérer avec la surface de friction 118 et de préférence avec la denture et/ou la surface périphérique du premier mobile 111 et/ou du deuxième mobile 112 de sorte à réaliser une friction et/ou un frottement gras avec le premier mobile 111 et/ou le deuxième mobile 112.Still in the figures, the disengaging member 120 is provided with a retaining surface 124, and more particularly the retaining member 121 comprises the retaining surface 124. This retaining surface 124 can cooperate with the friction surface 118. and preferably with the teeth and / or the peripheral surface of the first mobile 111 and / or of the second mobile 112 so as to achieve friction and / or fatty friction with the first mobile 111 and / or the second mobile 112.

Selon un mode de réalisation, cette friction ou ce frottement gras est réalisable totalement ou partiellement grâce à la combinaison de l'organe de maintien 121 comprenant la surface de maintien 124 et du premier bras flexible 122, car, en effet, le premier bras flexible 122 va permettre d'ajuster la force de frottement ou la friction pour maintenir le premier mobile 111 et/ou le deuxième mobile 112 et de permettre à l'utilisateur d'effectuer la mise à l'heure sans avoir à exercer une force trop importante ce qui permet de minimiser l'usure et éviter une casse des pièces. À cet effet, il peut être éventuellement prévu un réservoir sur le premier mobile 111 et/ou le deuxième mobile 112. Ce réservoir peut être configuré pour contenir un lubrifiant pour lubrifier lorsque l'organe de maintien 121 est au contact de la surface de friction 118 et de préférence de la denture et/ou la surface périphérique du premier mobile 111 et/ou du deuxième mobile 112 et ainsi minimiser l'usure de l'organe de maintien 121 et de la surface de friction 118 et de préférence de la denture et/ou la surface périphérique.According to one embodiment, this friction or this fatty friction can be achieved totally or partially thanks to the combination of the holding member 121 comprising the holding surface 124 and of the first flexible arm 122, because, in fact, the first flexible arm 122 will make it possible to adjust the frictional force or the friction to maintain the first mobile 111 and / or the second mobile 112 and to allow the user to set the time without having to exert too much force which makes it possible to minimize wear and avoid part breakage. For this purpose, a reservoir may optionally be provided on the first mobile 111 and / or the second mobile 112. This reservoir can be configured to contain a lubricant for lubricating when the holding member 121 is in contact with the friction surface. 118 and preferably of the teeth and / or the peripheral surface of the first mobile 111 and / or of the second mobile 112 and thus minimize the wear of the retaining member 121 and of the friction surface 118 and preferably of the teeth and / or the peripheral surface.

Ce réservoir peut prendre la forme d'un organe de guidage 119 sur le premier mobile 111 et/ou le deuxième mobile 112 de sorte à guider et/ou à lubrifier ledit moins un organe de maintien 121 lorsqu'il est au contact de la surface de friction 118 et de préférence de la denture et/ou de la surface périphérique dudit premier mobile 111 et/ou dudit deuxième mobile 112.This reservoir may take the form of a guide member 119 on the first mobile 111 and / or the second mobile 112 so as to guide and / or lubricate said at least one holding member 121 when it is in contact with the surface. friction 118 and preferably the teeth and / or the peripheral surface of said first mobile 111 and / or said second mobile 112.

Comme susmentionné, l'organe de maintien 121 est déplacé au contact du premier mobile 111 et/ou du deuxième mobile 112. Ce déplacement est réalisé par un pivotement ou un basculement de l'organe de débrayage 120 autour d'un axe de pivotement 123.As mentioned above, the holding member 121 is moved in contact with the first mobile 111 and / or the second mobile 112. This movement is achieved by a pivoting or a tilting of the disengaging member 120 about a pivot axis 123. .

En effet, l'organe de débrayage 120 est configuré pour pivoter autour de l'axe de pivotement 123 de sorte à se déplacer entre ladite position d'embrayage 101 et ladite position de débrayage 102, ce qui permet le déplacement de l'organe de maintien 121 au contact de ladite surface de friction 118 et selon certain mode de réalisation, l'organe de débrayage 120 peut être une bascule 120.Indeed, the disengaging member 120 is configured to pivot about the pivot axis 123 so as to move between said clutch position 101 and said disengaged position 102, which allows the movement of the disengaging member. maintaining 121 in contact with said surface of friction 118 and according to a certain embodiment, the clutch member 120 may be a rocker 120.

Lors de ce pivotement ou de ce basculement, le mobile intermédiaire 113, étant disposé sur l'organe de débrayage 120, est de préférence monté pivotant sur un axe de renvoi 127 pouvant être distinct et/ou distant de l'axe de pivotement 123. En effet, selon un mode de réalisation (non représenté), l'organe de débrayage 120 peut comprendre un pignon coulant monté sur l'axe de pivotement de sorte que l'axe de pivotement et l'axe de renvoi soit d'une part confondu et d'autre part que lorsque l'organe de débrayage 120 se déplace de la position d'embrayage à la positon de débrayage, le pignon coulant pivote en même temps que l'organe de débrayage 120 et est accompagné d'un mouvement de translation vers le bas ou le haut de sorte le mobile intermédiaire 113 ne soit plus en contact avec le premier mobile 111 et/ou le deuxième mobile 112.During this pivoting or this tilting, the intermediate mobile 113, being disposed on the disengaging member 120, is preferably mounted to pivot on a deflection axis 127 which may be separate and / or distant from the pivot axis 123. Indeed, according to one embodiment (not shown), the clutch member 120 may comprise a sliding pinion mounted on the pivot axis so that the pivot axis and the return axis are on the one hand merged and on the other hand that when the disengaging member 120 moves from the clutch position to the disengaging position, the sliding pinion pivots at the same time as the disengaging member 120 and is accompanied by a movement of translation downward or upward so that the intermediate mobile 113 is no longer in contact with the first mobile 111 and / or the second mobile 112.

Ainsi, indépendamment du fait que l'axe de renvoi 127 soit distinct ou confondu de l'axe de pivotement 123, le mobile intermédiaire 113 peut être déplacé entre ladite position d'embrayage 101 et ladite position de débrayage 102 lorsque l'organe de débrayage 120 est déplacé.Thus, regardless of whether the return axis 127 is separate or coincident with the pivot axis 123, the intermediate mobile 113 can be moved between said clutch position 101 and said disengaged position 102 when the disengaging member 120 is moved.

Selon un autre mode de réalisation, le mobile intermédiaire 113 est disposé entre ledit axe de pivotement 123 et le bras d'actionnement 125. Un avantage de cette disposition est de permettre au mobile intermédiaire 113 de rester en mouvement et/ou au contact du premier mobile 111 tout en étant débrayé du deuxième mobile 112, ou vice versa. Ainsi, lorsque l'organe de débrayage 120 se déplace de la position de débrayage 102 vers la position d'embrayage 101, le mouvement du mobile associé au déplacement de l'organe de débrayage 120 réduit les risques d'avoir un contact dent contre dent car d'une part le mobile se déplace dans un plan, faisant un angle compris entre 0° et 10°, notamment entre 0° et 7° et de préférence entre 0° et 5° avec le premier mobile 111 et/ou le deuxième mobile 112, et d'autre part il reste en mouvement. Donc lorsque le mobile intermédiaire 113 revient en position d'embrayage 101, plus exactement lorsque l'organe de débrayage 120 se déplace vers la position d'embrayage 101, le mobile intermédiaire 113 continue sa rotation autour de l'axe de renvoi 127 et vient engrener le premier mobile 111 ou le deuxième mobile 112.According to another embodiment, the intermediate mobile 113 is disposed between said pivot axis 123 and the actuating arm 125. An advantage of this arrangement is to allow the intermediate mobile 113 to remain in motion and / or in contact with the first. mobile 111 while being disengaged from the second mobile 112, or vice versa. Thus, when the disengaging member 120 moves from the disengaging position 102 to the clutch position 101, the movement of the mobile associated with the movement of the disengaging member 120 reduces the risks of having tooth against tooth contact. because on the one hand the mobile moves in a plane, making an angle between 0 ° and 10 °, in particular between 0 ° and 7 ° and preferably between 0 ° and 5 ° with the first mobile 111 and / or the second mobile 112, and on the other hand it remains in motion. So when the intermediate mobile 113 returns to clutch position 101, more exactly when the disengaging member 120 moves towards the clutch position 101, the intermediate mobile 113 continues its rotation around the return axis 127 and engages the first mobile 111 or the second mobile 112.

Par ailleurs, l'organe de débrayage 120 comprend éventuellement un deuxième bras flexible 126 configuré pour déplacer l'organe de débrayage 120 de la position de débrayage 102 vers la position d'embrayage 101 lorsque l'organe de commande 130, et par extension le plot 135 susmentionné, se déplace de la deuxième position 132 vers la première position 131. Plus particulièrement, ce deuxième bras flexible 126 peut se déformer élastiquement et ainsi de déplacer le mobile intermédiaire 113 d'une manière plus souple vers la position d'embrayage 101.Furthermore, the disengaging member 120 optionally comprises a second flexible arm 126 configured to move the disengaging member 120 from the disengaged position 102 to the clutch position 101 when the control member 130, and by extension the abovementioned stud 135, moves from the second position 132 to the first position 131. More particularly, this second flexible arm 126 can be elastically deformed and thus move the intermediate mobile 113 in a more flexible manner towards the clutch position 101 .

Enfin, le rouage d'horlogerie 100 peut comprendre une goupille 139 de sorte que lorsque le bras d'actionnement 125 est en butée contre cette goupille 139 en première position 131 ou en position d'embrayage 101, le mobile intermédiaire 113 et au moins un des premier ou deuxième mobiles 111, 112, sont en contact au niveau de leurs cercles primitifs respectif de sorte que la transmission du mouvement soit optimale.Finally, the clockwork gear 100 can include a pin 139 so that when the actuating arm 125 is in abutment against this pin 139 in the first position 131 or in the clutch position 101, the intermediate mobile 113 and at least one first or second mobile 111, 112, are in contact at their respective pitch circles so that the transmission of the movement is optimal.

En somme, la figure 1 représente l'organe de commande 130 tirant l'organe de débrayage 120 par l'intermédiaire du plot 135 qui contraint le deuxième bras flexible 126 de l'organe de débrayage 120.In short, the figure 1 shows the control member 130 pulling the disengaging member 120 by means of the stud 135 which forces the second flexible arm 126 of the disengaging member 120.

L'organe de débrayage 120 est en butée contre la goupille 139 et comprend le mobile intermédiaire 113, aussi appelé renvoi 113, qui engrène avec la roue du deuxième mobile 112. L'organe de maintien 121 de l'organe de débrayage 120 n'est pas en contact avec la surface de friction 118 et de préférence avec la denture et/ou la surface périphérique. Ainsi, le premier mobile 111 entraine le deuxième mobile 112 par l'intermédiaire du mobile intermédiaire 113.The disengaging member 120 is in abutment against the pin 139 and comprises the intermediate mobile 113, also called return 113, which meshes with the wheel of the second mobile 112. The retaining member 121 of the disengaging member 120 n ' is not in contact with the friction surface 118 and preferably with the toothing and / or the peripheral surface. Thus, the first mobile 111 drives the second mobile 112 via the intermediate mobile 113.

Sur la figure 2, l'organe de commande 130 est déplacé et le plot 135 perd son contact avec le deuxième bras flexible 126 et vient en contact avec le bras d'actionnement 125 de l'organe de débrayage 120 ce qui le déplace en rotation. Le renvoi 113 reste engrené avec le pignon du premier mobile 111 mais dégrène avec le deuxième mobile 112. L'organe de maintien 121 vient en contact avec la surface de friction 118 et de préférence avec la denture et/ou la surface périphérique par l'intermédiaire de l'organe de maintien 121 ce qui maintien le deuxième mobile 112 en place, au jeu d'engrenage près.On the figure 2 , the control member 130 is moved and the stud 135 loses its contact with the second flexible arm 126 and comes into contact with the actuating arm 125 of the clutch member 120 which moves it in rotation. The return 113 remains meshed with the pinion of the first mobile 111 but disengages with the second mobile 112. The retaining member 121 comes into contact with the friction surface 118 and preferably with the toothing and / or the peripheral surface via the intermediate of the retaining member 121 which keeps the second mobile 112 in place, except for the gear play.

Ainsi, le premier mobile 111 continue à tourner et le deuxième mobile 112 est arrêté et maintenu par l'organe de débrayage 120 via l'organe de maintien 121.Thus, the first mobile 111 continues to rotate and the second mobile 112 is stopped and held by the disengaging member 120 via the holding member 121.
