  • said second axis of rotation is perpendicular to said first axis of rotation.
  • said at least one drive member assembly comprises a universal joint and at least one third drive member; said at least one third drive member being disposed at the end of said rotary element so as to drive said seconds hand, said minute hand or said hour hand around the first axis of rotation.
  • the present invention illustrated in figure 1 , is in the form of a display mechanism 100 for a watch and more exactly the display mechanism 100 of a watch.
  • this display mechanism 100 may comprise at least one indicator member 110 and at least one set of drive member 120.
  • the indicator member 110 can be mounted to be movable in rotation around a first axis of rotation 101 by means of a first part 103 and which can serve as a barrel 103 , according to the embodiments, as can be observed on the figure. figure 2 .
  • This first part 103 moves opposite a scale and preferably opposite a dial 105 on which can be represented, for example, a scale representing lunar phases, a date and / or a time. , that is to say a scale representing the hours, minutes, seconds or any graduations less than the second such as the hundredth of a second or others.
  • this scale can represent the power reserve, the tachometer, the day of the week, the month of the year, the zodiac, the temperature, the pressure, the altitude, the depth, the weather forecast, the time zone. schedule or any other indication relevant to the user.
  • the indicator member 110 may also be movable in rotation about a second axis of rotation 102.
  • This second axis of rotation 102 may be secant and / or perpendicular to the first axis of rotation 101 , and, according to one embodiment, this second axis of rotation 102 may be coplanar with the scale or with the dial 105 and the first axis of rotation 101 may be in a plane different from that of the second axis of rotation 102.
  • This second axis of rotation 102 extends longitudinally along the indicator member 110 and can be embodied by a second part 104 which extends longitudinally along the indicator member 110.
  • the indicator member 110 can also be made up of a rotary element 111 which can be mounted to be movable in rotation around the second axis of rotation 102 by means of the second part 104.
  • 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 .
  • 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.
  • 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.
  • 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.
  • the rotary element 111 can also represent an object, a sculpture and / or a miniature of an object comprising a second piece of information.
  • 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.
  • 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 .
  • 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.
  • 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.
  • 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.
  • the drive member assembly 120 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.
  • the drive member assembly 120 may be a universal joint, as shown in FIGS. figures 5A, 5B and 5C .
  • the first drive member 121 which is movable in rotation about the first axis of rotation 101 instead of the indicator member 110.
  • 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 .
  • 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.
  • 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.
  • 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 .
  • 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.
