Definitions

  • the technical field of the present invention concerns that of watchmaking, and more precisely that of display mechanisms.
  • the document JPH01193687A shows indicators that allow both the display of time information and the display of a moving pattern. However, the indicators only show one piece of information.
  • the indicator is mobile in rotation around two distinct axes of said dial, the second hand, the minute hand or the hour hand.
  • said at least one first drive member is secured respectively to said dial, a second hand, a minute hand or an hour hand.
  • said first part is a barrel and/or said second part is the second axis of rotation and extends longitudinally along said at least one indicator member.
  • said at least one drive member assembly is at least one gear assembly comprising at least one first gear member and at least one second gear member, at least one micro-bearing assembly comprising at least one first micro-bearing and at least one second micro-bearing, and/or at least one bearing assembly comprising at least one first bearing and at least one second bearing.
  • said at least one rotating element is a counterweight of said at least one indicator member, a counterweight of a second hand, a counterweight of a minute hand or a counterweight of an hour hand and wherein said at least one indicator member is a body of a second hand, a body of a minute hand or a body of an hour hand.
  • the counterweight of the indicator organ is mobile in rotation around two separate axes.
  • said at least one indicator member is a second hand, a minute hand or an hour hand.
  • said second axis of rotation is coplanar with said dial and said first axis of rotation is in a plane different from said second axis of rotation.
  • 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 arranged at the end of said rotating element so as to drive said second hand, said minute hand or said hour hand around the first axis of rotation.
  • the present invention illustrated in the Figure 1 , is presented in the form of a display mechanism 100 for a watch and more precisely 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 members 120.
  • the indicator member 110 can be mounted to rotate about a first axis of rotation 101 by means of a first part 103 and which can serve as a barrel 103, depending on the embodiments, as can be seen in the 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, the minutes, the 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, pressure, altitude, depth, the weather forecast, the time zone or any other indication relevant to the user.
  • the indicator member 110 can also be movable in rotation around a second axis of rotation 102.
  • This second axis of rotation 102 can be secant and/or perpendicular to the first axis of rotation 101, and, according to one embodiment, this second axis of rotation 102 can be coplanar to the scale or to the dial 105 and the first axis of rotation 101 can 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 composed of a rotary element 111 which can be mounted to rotate about the second axis of rotation 102 by means of the second part 104.
  • the display mechanism may also comprise a drive assembly 120.
  • This drive assembly may comprise a first drive member 121 and a second drive member 122, as can be seen in the Figures 2 to 5A, 5B And 5C .
  • the second drive member 122 may be arranged on and/or in said at least one rotary element 111, and may be driven by the first drive member 121.
  • the latter i.e. the first drive member 121, may be configured to cooperate with the second drive member 122 so as to drive the rotary element 111 with a rotational movement around the second axis of rotation 102.
  • the view of the mechanism on the Figure 2 and the enlargement 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 engaged by the first drive member 121 which drives the rotary element 111 in rotation about the second axis of rotation 102 when the indicator member 110 can be rotated about the first axis of rotation 101.
  • the rotary element 111 can comprise information which will be revealed as the indicator member 110 rotates about 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 information.
  • the hand of the dial that is to say the hand which belongs to a dial with a scale or an indication, can be movable in rotation around two very distinct axes, and indicates two equally distinct pieces of information.
  • the sectional view shown on the Figure 4 shows an example location of the first drive member 121 and the second drive member 122.
  • the speed of the rotating element 111 about the second axis of rotation 102 can therefore be determined by the location of the first drive member 121 and the second drive member 122 on the one hand and on the other hand by the ratio, for example gear ratio, between the first drive member 121 and the second drive member 122.
  • the first drive member 121 can be integral with the scale, as mentioned above, of the dial 105, the second hand 106, the minute hand 107 or the hour hand 108 and/or the second drive member 122 can be integral with the hour hand 108, the minute hand 107 or the second hand 106, depending on whether the indicating member 110 is the second hand 106, the minute hand 107 or hour hand 108.
  • a counterweight 109 may be necessary to counterbalance the imbalance generated by the weight of the second hand 106, the minute hand 107 or the hour hand 108 when the indicating member 110 is a second hand 106, a minute hand 107 or an hour hand 108 respectively.
  • the rotating element can be placed on the counterweight 109 of the second hand 106, the minute hand 107 or the hour hand 108. Therefore, the counterweight 109 of the hand can be movable both in rotation about the first axis of rotation 101 and about 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 micro-bearing assembly comprising a first micro-bearing and a second micro-bearing, and/or a bearing assembly comprising a first bearing and a second bearing.
  • the drive member assembly 120 may be a universal joint, as shown in Figures 5A, 5B and 5C .
  • the first drive member 121 which is rotatable around the first axis of rotation 101 instead of the indicator member 110.
  • the second part 104 i.e. the rotating element 111, rotates around the second axis of rotation 102 without being in rotation around the first axis of rotation 101.
  • the drive member assembly may also comprise, in this embodiment, at least one third drive member 123, which may be arranged at the end of the rotating element 110 for example, as can be seen in the Figure 5A , so as to drive said second 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 of rotation 102.
  • at least one third drive member 123 which may be arranged at the end of the rotating element 110 for example, as can be seen in the Figure 5A , so as to drive said second 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 of rotation 102.
  • the rotating element 110 only moves about the second axis of rotation 102. If additional movement is desired, it may be necessary to add at least a third drive member 123, so that when the first drive member 121 is rotatable about the first axis of rotation 101, the second drive member 122, and by extension the rotating element 111 according to one embodiment, is rotating about the second axis of rotation 102, and the third drive member 123 drives the rotating element 111 to rotate about the first axis of rotation 101.
  • the rotating element 111 may comprise a second information which will be revealed as the indicator member 110 rotates around the first axis of rotation 101 and indicates a first piece of information.
