Cet ensemble d'entraînement peut comprendre un premier organe d'entraînement 121 et un deuxième organe d'entraînement 122, comme cela est visible sur les figures 2 à 5A, 5B et 5C.As mentioned previously, the display mechanism may also include a drive assembly 120. This drive assembly may include a first drive member 121 and a second drive member 122 , as can be seen on the figures 2 to 5A , 5B and 5C .

Le deuxième organe d'entraînement 122 peut être disposé sur et/ou dans ledit au moins un élément rotatif 111, et peut être entraîné par le premier organe d'entraînement 121. Ce dernier, c'est-à-dire le premier organe d'entraînement 121, peut être configuré pour coopérer avec le deuxième organe d'entraînement 122 de manière à animer l'élément rotatif 111 d'un mouvement en rotation autour du deuxième axe de rotation 102. The second drive member 122 may be disposed on and / or in said at least one rotary member 111 , and may be driven by the first drive member 121. The latter, that is to say the first member d 'drive 121 , can be configured to cooperate with the second drive member 122 so as to animate the rotary element 111 with a rotational movement about the second axis of rotation 102.

En effet, la vue du mécanisme sur la figure 2 et l'agrandissement de la figure 3 montrent bien que lorsque l'organe indicateur 110 peut être mobile en rotation autour dudit premier axe de rotation 101, le deuxième organe d'entraînement 122 peut être engrené par le premier organe d'entraînement 121 ce qui entraîne l'élément rotatif 111 en rotation autour du deuxième axe de rotation 102 lorsque l'organe indicateur 110 peut être en rotation autour du premier axe de rotation 101. Ainsi, l'élément rotatif 111 peut comprendre une information qui se dévoilera au fur et à mesure que l'organe indicateur 110 tournera autour du premier axe de rotation 101. Bien évidemment, l'élément rotatif 111 peut également représenter un objet, une sculpture et/ou une miniature d'un objet comportant une deuxième information. Ainsi, l'aiguille du cadran, c'est-à-dire l'aiguille qui appartient à un cadran avec une échelle ou une indication, peut être mobile en rotation autour de deux axes bien distincts, et indique deux informations également bien distinctes. La vue en coupe représentée sur la figure 4 montre un exemple d'emplacement du premier organe d'entraînement 121 et du deuxième organe d'entraînement 122. Indeed, the view of the mechanism on the figure 2 and the expansion of the figure 3 clearly show that when the indicator member 110 can be movable in rotation about said first axis of rotation 101 , the second drive member 122 can be meshed by the first drive member 121 which drives the rotary member 111 in rotation around the second axis of rotation 102 when the indicator member 110 can be rotated around the first axis of rotation 101. Thus, the rotary member 111 can include information which will be revealed as the indicator member 110 will rotate around the first axis of rotation 101. Obviously, the rotary element 111 can also represent an object, a sculpture and / or a miniature of an object comprising a second piece of information. Thus, the dial needle, that is to say the needle that belongs to a dial with a scale or an indication, can be rotatable. around two very distinct axes, and indicates two equally distinct pieces of information. The sectional view shown on figure 4 shows an example of the location of the first drive member 121 and the second drive member 122.

La vitesse de l'élément rotatif 111 autour du deuxième axe de rotation 102 peut être donc déterminée par l'emplacement du premier organe d'entraînement 121 et du deuxième organe d'entraînement 122 d'une part et d'autre part par le rapport, par exemple d'engrenage, entre le premier organe d'entraînement 121 et le deuxième organe d'entraînement 122. Par exemple, le premier organe d'entraînement 121 peut être solidaire de l'échelle, comme mentionné précédemment du cadran 105, de l'aiguille des secondes 106, de l'aiguille des minutes 107 ou de l'aiguille des heures 108 et/ou le deuxième organe d'entraînement 122 peut être solidaire, de l'aiguille des heures 108, de l'aiguille des minutes 107 ou de l'aiguille des secondes 106, selon que l'organe indicateur 110 soit l'aiguille des secondes 106, l'aiguille des minutes 107 ou l'aiguille des heures 108. The speed of the rotary element 111 around the second axis of rotation 102 can therefore be determined by the location of the first drive member 121 and of the second drive member 122 on the one hand and on the other hand by the ratio , for example a gear, between the first drive member 121 and the second drive member 122 . For example, the first drive member 121 may be integral with the scale, as mentioned above, of the dial 105 , of the seconds hand 106 , of the minute hand 107 or of the hour hand 108 and / or the second drive member 122 may be integral with the hour hand 108 , the minute hand 107 or the seconds hand 106 , depending on whether the indicator member 110 is the seconds hand 106 , minute hand 107 or hour hand 108.

Par ailleurs, selon où l'élément rotatif peut être placé, un contrepoids 109 peut être nécessaire pour contrebalancer le balourd généré par le poids de l'aiguille des secondes 106, l'aiguille des minutes 107 ou l'aiguille des heures 108 lorsque l'organe indicateur 110 est une aiguille des secondes 106, une aiguille des minutes 107 ou une aiguille des heures 108 respectivement.Also, depending on where the rotating element may be placed, a counterweight 109 may be needed to counterbalance the unbalance generated by the weight of the seconds hand 106 , the minute hand 107, or the hour hand 108 when the weight of the seconds hand 106, the minute hand 107 or the hour hand 108 occurs. The indicator member 110 is a seconds hand 106 , a minute hand 107 or an hour hand 108 respectively.

Selon un mode de réalisation, l'élément rotatif peut être placé sur le contrepoids 109 de l'aiguille des secondes 106, de l'aiguille des minutes 107 ou de l'aiguille des heures 108. Dès lors, le contrepoids 109 de l'aiguille peut être mobile à la fois en rotation autour du premier axe de rotation 101 et autour du deuxième axe de rotation 102. According to one embodiment, the rotating element can be placed on the counterweight 109 of the seconds hand 106 , of the minute hand 107 or of the hour hand 108. Therefore, the counterweight 109 of the needle can be movable both in rotation around the first axis of rotation 101 and around the second axis of rotation 102.

L'ensemble d'organe d'entraînement 120, mentionné précédemment, peut se présenter sous la forme d'un ensemble d'engrenages comprenant un premier organe d'engrenage 121 et un deuxième organe d'engrenage 122, un ensemble de micro-roulements comprenant un premier micro-roulement et un deuxième micro-roulement, et/ou un ensemble de paliers comprenant un premier palier et un deuxième palier. Dans certains modes de réalisations, l'ensemble d'organe d'entraînement 120 peut être un joint de cardan, comme cela est représenté sur les figures 5A, 5B et 5C.The drive member assembly 120 , mentioned above, may be in the form of a gear assembly comprising a first gear member 121 and a second gear member 122 , a set of micro-bearings comprising a first micro-bearing and a second micro-bearing, and / or a set of bearings comprising a first bearing and a second bearing. In some embodiments, the drive member assembly 120 may be a universal joint, as shown in FIGS. figures 5A, 5B and 5C .

Dans ce cas, contrairement au paragraphe précédent, c'est le premier organe d'entraînement 121 qui est mobile en rotation autour du premier axe de rotation 101 au lieu de l'organe indicateur 110. En effet, lorsque la première partie 103 du joint de cardan tourne autour du premier axe de rotation 101, la deuxième partie 104, c'est-à-dire l'élément rotatif 111, tourne autour du deuxième axe de rotation 102 sans pour autant être en rotation autour du premier axe de rotation 101. In this case, unlike the previous paragraph, it is the first drive member 121 which is movable in rotation about the first axis of rotation 101 instead of the indicator member 110. In fact, when the first part 103 of the seal of gimbal rotates around the first axis of rotation 101 , the second part 104 , that is to say the rotary element 111 , rotates around the second axis of rotation 102 without however being in rotation around the first axis of rotation 101 .

L'ensemble d'organe d'entraînement peut également comprendre, dans ce mode de réalisation, au moins un troisième organe d'entraînement 123, qui peut être disposé à l'extrémité de l'élément rotatif 110 par exemple, comme cela est visible sur la figure 5A, de sorte à entraîner ladite aiguille des secondes 106, ladite aiguille des minutes 107 ou ladite aiguille des heures 108 autour du premier axe de rotation 101, alors que le joint de cardan anime l'élément rotatif 110 d'une rotation autour du deuxième axe de rotation 102. The drive member assembly may also include, in this embodiment, at least one third drive member 123 , which may be disposed at the end of the rotary member 110 for example, as can be seen. on the figure 5A , so as to drive said seconds hand 106 , said minute hand 107 or said hour hand 108 around the first axis of rotation 101 , while the universal joint drives the rotary element 110 with a rotation around the second axis rotation 102.

En d'autres termes, l'élément rotatif 110 ne se meut qu'autour du deuxième axe de rotation 102. S'il est souhaité avoir un mouvement supplémentaire, il peut être nécessaire d'ajouter au moins un troisième organe d'entraînement 123, de sorte que quand le premier organe d'entraînement 121 est mobile en rotation autour du premier axe de rotation 101, le deuxième organe d'entraînement 122, et par extension l'élément rotatif 111 selon un mode de réalisation, est en rotation autour du deuxième axe de rotation 102, et le troisième organe d'entraînement 123 entraîne l'élément rotatif 111 en rotation autour du premier axe de rotation 101. Ainsi, l'élément rotatif 111 peut comprendre une deuxième information qui se dévoilera au fur et à mesure que l'organe indicateur 110 tournera autour du premier axe de rotation 101 et indique une première information.In other words, the rotary element 110 only moves around the second axis of rotation 102 . If it is desired to have additional movement, it may be necessary to add at least a third drive member 123 , so that when the first drive member 121 is movable in rotation about the first axis of rotation 101 , the second drive member 122 , and by extension the rotary element 111 according to one embodiment, is in rotation about the second axis of rotation 102 , and the third drive member 123 drives the rotary member 111 in rotation around of the first axis of rotation 101 . Thus, the rotary element 111 may include a second information which will be revealed as the indicator member 110 rotates around the first axis of rotation 101 and indicates a first item of information.
