Claims 1 / 1 page 2 CN 121742166 A Watchmaking Technology Field Including a Watch Movement Having a Moon Phase Display Device and a Earth Phase Display Device
[0001] The present invention relates to the field of watches, and more particularly to a device for displaying time values on a watch.
[0002] More specifically, the present invention relates to a watch whose movement includes a moon phase display device and a land phase display device. Background Art
[0003] Moon phase displays are quite common in the field of horology, as are land phase displays; in other words, a land phase display is a view of a portion of the Earth from the Moon.
[0004] Moon phase displays or land phase displays greatly increase the complexity of watch movements that include these devices.
[0005] In addition, for aesthetic reasons, it may be desirable to display both the moon phase and the land phase simultaneously.
[0006] The present invention meets this need while simplifying the movement mechanism for simultaneously displaying the moon phase and the land phase to the greatest extent possible. Summary of the Invention

[0014] In a particular embodiment, the shielding member of the geodetic display device has two shielding elements arranged opposite each other in a diametrical direction and extending along a longitudinal axis between a first end through which they are rotated and a free second end.
[0015] In a particular embodiment, each shielding element includes two side edges symmetrical about the longitudinal axis, each side edge forming a convex edge.
[0016] In a particular embodiment, the convex edge has a vertex whose orthogonal projection on the longitudinal axis is closer to the first end of the shielding element than to the second end.
[0017] In a particular embodiment, the geodetic diagram is formed on a disc-shaped support member attached to the structure of a watch movement in a manner without degrees of freedom, for example, by bonding to said structure.
[0018] In a particular embodiment, the shielding member is fixed to the phase tube in a synchronous rotational manner, and the tube wheel attached to the phase tube engages with a driving motion member via an intermediate wheel, the driving motion member including a pivot handle on which the phase tube is rotatably mounted.

[0023] FIG3 shows a cross-sectional view of the table in FIG1 along axis A-A,
[0024] FIG4 shows a perspective view of the shielding member of the phase display device in FIG1.
[0025] It should be noted that these figures are not necessarily drawn to scale for clarity. Detailed Description
[0026] The present invention relates to a watch 10, which includes a watch movement 100, the watch movement 100 including a moon phase display device 11 and a land phase display device 12.
[0027] The watch 10 is also provided with a dial 13, in which a first hole 130 and a second hole 131 are respectively designed to display the land phase and the moon phase, as shown in the front view of FIG1.
[0028] The land phase display device 12 includes a globe diagram 120, which is fixedly arranged relative to the dial 13 and faces the first hole 130. In the exemplary embodiment of the invention shown in the figure, the globe diagram 120 is formed on a disc-shaped support member 121, and the first hole 130 is substantially semi-circular. It should be noted that the support member 121 is plate-shaped, and its outline can adopt any suitable geometry. The support member 121 is attached to the structure of the watch movement 100 in a non-degree-of-freedom manner, preferably using, for example, an adhesive film 122 to bond to the structure. Therefore, the geodetic display device 12 can be easily assembled into the watch movement 100 in an industrial manner.
[0029] The geodetic display device 12 also includes a shield 123 inserted between the globe graphic 120 and the dial 13.
[0030] The shield 123 is arranged to be driven to rotate by a drive mechanism to hide the globe graphic 120. This drive mechanism is preferably formed by a first electric motor 125, the output of which can be seen in the cross-sectional view of FIG3.
[0031] Advantageously, the globe graphic 120 is produced on a background 124, which has the same appearance as the shield 123. For example, the background 124 and the shield 123 have the same monochrome color.
[0032] In a preferred exemplary embodiment, as shown in FIG3, the shield 123 can be pressed into the geodetic tube 126, to which a tube wheel 127 is attached.The tube wheel 127 engages with the drive motion member 128 via the intermediate wheel 129. The drive motion member 128 is preferably directly connected to the first electric motor 125 and includes a pivot 1280 on which the phase tube 126 is slidably mounted. In other words, the shield 123 is fixed to the phase tube 126 such that it rotates with the phase tube 126, while the phase tube 126 is freely pivotable relative to the pivot 1280.
[0033] Advantageously, the moon phase display device 11 includes a display element 110 arranged facing the second hole 131 and rotatable relative to the dial 13. The display element 110 includes two lunar symbols 111 facing each other in the diametrical direction. The display element 110 is preferably in the form of a disc, as shown in the exploded view of FIG2. The shape of the second hole 131 is formed such that the dial constitutes a shield in a manner known per se, which can be hidden behind the shield when the display 110 is rotated.
[0034] Thus, the earth phase and the moon phase can be seen through two separate holes, thereby enhancing the decorative appearance of the watch 10.
[0035] The display 110 of the moon phase display device 11 is driven to rotate by a drive mechanism, which is preferably formed by a second electric motor, different from the first electric motor 125 connected to the shield 123. Thus, the drive mechanism for the moon phase display and the drive mechanism for the earth phase display are independent of each other. This feature is particularly advantageous because it allows the moon phase display and the earth phase display to be set separately.
[0036] The electric motor for driving the shield 123 and the electric motor for driving the display 110 of the moon phase display device 11 are designed to be powered by a power source, preferably by the same battery.
[0037] It should be noted that Table 10 according to the invention may advantageously include an electric motor designed to power each function provided by Table 10, such as current time indication, timing function, indication of additional time zone, date indication, etc.
[0038] Figures 2 and 4 show a preferred exemplary embodiment of the shielding member 123, wherein the shielding member 123 has two identical shielding elements 1230, which are opposite each other in the diametrical direction. Each shielding element 1230 is elongated and extends along a longitudinal axis between a first end and a second end, the first end being the end through which the shielding member 123 rotates, and the second end being a free end.
[0039] Each shielding element 1230 includes two side edges symmetrical about the longitudinal axis, each side edge forming a convex edge 1231.
[0040] In particular, as shown in Figure 4, the convex edge 1231 has a vertex whose orthogonal projection on the longitudinal axis is closer to the first end of the shielding element 1230 than to the second end. A vertex is defined as the point on each side edge that is farthest from the longitudinal axis.
[0041] When the shielding member 123 partially or completely covers the Earth diagram 120, these features allow for the reproduction of the lunar shadow's projection on the Earth as faithfully as possible.
[0042] To display the lunar and terrestrial phases as accurately as possible and to make the appearance of the watch 10 as attractive as possible, the display member 110 of the lunar phase display device 11 and the shielding member 123 of the terrestrial phase display device 12 rotate in opposite directions.
[0043] In particular, in a preferred exemplary embodiment, the first and second motors are controlled by electronic circuitry connected to them, as is known to those skilled in the art.
[0044] It should be noted that, for clarity, components of the watch movement 100 known to those skilled in the art are not described herein and are not shown in the figures.
[0045] Furthermore, it should be noted that the embodiments and uses considered above have been described by way of non-limiting examples, and other variations are therefore conceivable.
[0046] Specifically, the shielding member 123 and the display member 110 may be driven by the same motor, which is designed to be powered by a power source that may or may not be shared.
[0047] Alternatively, the shielding element 123 and the display element 110 may be driven by the same drive mechanism, which is formed by a spring barrel kinematically connected to the speed regulating mechanism.
[0048] In the last two examples above, the display element 110 of the moon phase display device 11 and the shielding element 123 of the earth phase display device 12 can be rotated in opposite directions by a rotatable intermediate wheel arranged in the kinematic chain, which can be easily integrated by those skilled in the art.Page 3 / 3 of the specification 5 CN 121742166 A Figure 1 Figure 2 Page 1 / 2 of the drawings of the specification 6 CN 121742166 A Figure 3 Figure 4 Page 2 / 2 of the drawings of the specification 7 CN 121742166 A Abstract The present invention relates to a watch (10) including a dial (13) and a watch movement (100), the said watch movement comprising a moon phase display device (11) and an earth phase display device (12), the said earth phase display device (12) comprises an earth illustration (120) and a shielding member (123); the said earth illustration is fixedly arranged relative to the dial (13) and faces a first hole (130) formed in the dial (13); the said shielding member (123) is rotated by a driving mechanism and is arranged between the earth illustration (120) and the dial (13); the said moon phase display device (11) comprises a display member (110), which is arranged facing a second hole (131) formed in the dial (13), and is driven by a driving mechanism to rotate relative to the dial (13); the display member (110) comprises two moon illustrations (111).。
