Technical Field
[0001] This invention relates to the field of clocks and watches, and more particularly to a device for displaying time values on clocks and watches.
[0002] More specifically, the present invention relates to a watch whose movement includes a moon phase display device and a ground phase display device. Background Technology
[0003] Moon phase displays are quite common in the watchmaking industry, and so are terrestrial phase displays; in other words, terrestrial phase displays show a portion of the Earth visible from the Moon.
[0004] Moon phase displays or terrestrial phase displays greatly increase the complexity of watch movements that include these devices.
[0005] Additionally, for aesthetic reasons, it may be desirable to display both the lunar phase and the Earth phase simultaneously.
[0006] This invention meets this requirement while simplifying the motion mechanism for simultaneously displaying lunar and terrestrial phases to the greatest extent possible. Summary of the Invention
[0007] Therefore, the present invention relates to a watch including a dial and a watch movement, the watch movement including a moon phase display device and a ground phase display device.
[0008] The geodetic display device includes a globe and a shield. The globe is fixed relative to the dial and faces the first hole in the dial. The shield is driven to rotate by a drive mechanism and is inserted between the globe and the dial.
[0009] The moon phase display device includes a display element arranged facing a second hole formed in the dial and driven by a drive mechanism to rotate relative to the dial. The display element includes two moon diagrams.
[0010] In certain embodiments, the invention may also include one or more of the following features, which may be used individually or in any technically feasible combination.
[0011] In a particular embodiment, the shielding element and the display element are driven to move by two separate drive mechanisms, each formed by an electric motor designed to be powered by a power source.

[0014] In a particular embodiment, the shielding element of the ground phase 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 that are symmetrical about the longitudinal axis, and each side edge forms 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 shading element than to the second end.
[0017] In a particular embodiment, the globe is formed on a disc-shaped support that is attached to the structure of the watch movement in a non-degree-of-freedom manner, for example, by bonding it to the 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 the driving motion member via an intermediate wheel. The driving motion member includes a pivot handle, on which the phase tube is mounted in a rotatable manner.

[0021] Figure 1 A front view of a table including a device for displaying lunar phases and terrestrial phases, according to a preferred embodiment of the present invention, is shown.

[0023] Figure 3 Show Figure 1 The table in the image is a cross-sectional view along axis AA.
[0024] Figure 4 Show Figure 1 A perspective view of the shielding element of the ground phase display device.
[0025] It should be noted that these figures are not necessarily drawn to scale for clarity. Detailed Implementation
[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 ground phase display device 12.
[0027] Table 10 also includes a dial 13, in which the first hole 130 and the second hole 131 are designed to display the Earth phase and the lunar phase, respectively. Figure 1 The front view is shown in the image.
[0028] The geodetic display device 12 includes a globe diagram 120, which is fixedly arranged relative to the dial 13 and faces the first aperture 130. In the exemplary embodiment of the invention shown in the figures, the globe diagram 120 is formed on a disc-shaped support 121, and the first aperture 130 is substantially semi-circular. It should be noted that the support 121 is plate-shaped, and its outline can adopt any suitable geometry. The support 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. 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 shielding member 123 inserted between the globe map 120 and the dial 13.
[0030] The shielding element 123 is arranged to rotate by a drive mechanism to conceal the globe illustration 120. This drive mechanism is preferably formed by a first electric motor 125, the output of which can be... Figure 3 As seen in the cross-sectional view.
[0031] Advantageously, the globe illustration 120 is generated on the background 124, and its appearance is identical to that of the masking element 123. For example, the background 124 and the masking element 123 have the same monochrome color.
[0032] In a preferred exemplary embodiment, such as Figure 3 As shown, the shielding member 123 can be pressed into the phase tube 126, and the tube wheel 127 is attached to the phase tube 126. The tube wheel 127 engages with the drive mechanism 128 via an intermediate wheel 129. The drive mechanism 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 shielding member 123 is fixed to the phase tube 126 such that it rotates with the phase tube 126, while the phase tube 126 can pivot freely relative to the pivot 1280.
[0033] Advantageously, the moon phase display device 11 includes a display element 110 arranged facing the second aperture 131 and rotatable relative to the dial 13. The display element 110 includes two opposing moon symbols 111 along the diametrical direction. The display element 110 is preferably in the form of a disc, such as... Figure 2 As shown in the exploded view, the second hole 131 is shaped such that the dial forms a shield in a manner known per se, which can be hidden behind the shield when the display 110 is rotated.
[0034] Therefore, the terrestrial and lunar phases can be seen through two separate holes, thus enhancing the decorative appeal of Table 10.
[0035] The display element 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 shielding member 123. Therefore, the drive mechanism for the moon phase display and the drive mechanism for the terrestrial phase display are independent of each other. This feature is particularly advantageous because it allows for separate installation of the moon phase display and the terrestrial phase display.
[0036] The motor for driving the shield 123 and the 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, additional time zone indication, date indication, etc.
[0038] Figure 2 and Figure 4 A preferred exemplary embodiment of the shielding member 123 is shown, 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 is rotated, and the second end being a free end.
[0039] Each masking element 1230 includes two side edges that are symmetrical about the longitudinal axis, each side edge forming a convex edge 1231.
[0040] Especially Figure 4 As shown, the convex edge 1231 has a vertex whose orthogonal projection on the longitudinal axis is closer to the first end of the shading element 1230 than to the second end. The vertex is defined as the point on each side edge that is farthest from the longitudinal axis.
[0041] When the masking element 123 partially or completely covers the Earth diagram 120, these features enable the reproduction of the moon's shadow projection on the Earth as faithfully as possible.
[0042] In order to display the lunar and terrestrial phases as accurately as possible and to make the appearance of Table 10 as attractive as possible, the display element 110 of the lunar phase display device 11 and the shielding element 123 of the terrestrial phase display device 12 rotate in opposite directions.
[0043] In particular, in a preferred exemplary embodiment, the first motor and the second motor are controlled by electronic circuits connected to them, as is known to those skilled in the art.
[0044] It should be noted that, for clarity, the 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 element 123 and the display element 110 can be driven by the same motor, which is designed to be powered by a power source that can be shared or not.
[0047] Alternatively, the shielding member 123 and the display member 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 lunar 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, and can be easily integrated by those skilled in the art.
