Abstract
Description
Technical Field
[0001] This invention relates to a clock with a month display. Background Technology
[0002] Previously, clocks with a moon age display were known, which included a time display mechanism for showing the hour and a moon age display mechanism capable of displaying the moon's position or age in sync with the hour. Various techniques have been proposed for these clocks to improve the display and operability of various information.
[0003] For example, Patent Document 1 discloses a structure for an astronomical wristwatch capable of displaying the position of the moon on a dial that displays the time. Furthermore, References 2 and 3 disclose a structure for a clock with a moon age display that, in addition to displaying the time and the position of the moon, can also display the moon age synchronously with the time. Based on the prior art described in Patent Documents 1 to 3, it is possible to display the position of the moon in the sky or the moon age, etc.
[0004] [Prior Technology Documents] [Patent Literature] [Patent Document 1] Japanese Patent Publication No. 6-31721; [Patent Document 2] International Publication No. 2004 / 013708; [Patent Document 3] Japanese Patent Application Publication No. 60-31081. Summary of the Invention
[0005] [The problem the invention aims to solve] However, in the aforementioned prior art, when correcting the month's age or position (hereinafter referred to simply as month age information), the correction is achieved by rotating a knob linked to the time. For example, in correcting a 3-day deviation in the month's position, the knob (i.e., the hour hand) needs to be rotated 3 times (6 times in the case of a 12-hour clock), which is not very practical for operation. Therefore, there is a problem with the operability of correcting month age information in the prior art. Furthermore, there is room for improvement in displaying month age information more accurately.
[0006] Therefore, the object of the present invention is to provide a clock with a month display mechanism that can improve the display of month information and the operability during correction.
[0007] [Solutions for solving the problem] To address the aforementioned issues, one aspect of the present invention provides a clock with a moon age display, comprising: a dial for displaying the time; a moon age display mechanism having a moon wheel that displays the position of the moon synchronously with the time and a moon shadow wheel that displays the moon age based on a phase difference with the moon wheel; and a correction mechanism for correcting moon age information displayed in the moon age display mechanism, the correction mechanism comprising: a first correction mechanism operated by a lever that corrects the moon age information synchronously with the time; and a second correction mechanism having a different input path than the first correction mechanism, correcting the moon age information asynchronously with the time and more rapidly than the first correction mechanism.
[0008] Based on this configuration, a month age display mechanism that operates synchronously with time is provided, thus enabling accurate display of the month's position and age.
[0009] The correction mechanism comprises: a first correction mechanism that corrects the gestational age information synchronously with time via the operation of a handle; and a second correction mechanism with a different input path than the first correction mechanism. The second correction mechanism corrects the gestational age information asynchronously with time and more rapidly than the first correction mechanism. Thus, the user can use two correction modes corresponding to the correction amount. For example, when the correction amount is small, the gestational age information can be finely corrected using the first correction mechanism via the handle. On the other hand, when the correction amount is large (e.g., in cases of deviations of several days), the second correction mechanism can be used for dynamic correction. This eliminates the need for repeated handle rotations, improving operability during correction.
[0010] Therefore, it is possible to provide a clock with a month-age display that can improve the display of month-age information and the operability during correction.
[0011] In addition, the aforementioned lunar age display mechanism has a lunar age transmission wheel that simultaneously applies driving force to the aforementioned lunar wheel and the aforementioned lunar shadow wheel, and the aforementioned second correction mechanism has an operating part that allows the aforementioned lunar age transmission wheel to rotate directly.
[0012] Based on this configuration, the age transmission wheel can be directly rotated by operating the operating part of the second correction mechanism. Therefore, the age information can be corrected quickly.
[0013] In addition, the aforementioned operating part is a rod that rotates the aforementioned age transmission wheel by pushing.
[0014] Based on this configuration, the gestational age information can be easily corrected by pushing the lever. Furthermore, the aforementioned correction function can be achieved with a simple configuration.
[0015] One aspect of the present invention provides a clock with a moon age display, comprising: a dial for displaying the time; and a moon age display mechanism having a moon wheel that displays the position of the moon synchronously with the time and a moon shadow wheel that displays the age of the moon based on a phase difference with the moon wheel, the moon age display mechanism having a power integration mechanism that receives two power sources and integrates the two power sources as one power source and outputs it to at least one of the moon wheel and the moon shadow wheel.
[0016] Based on this configuration, a lunar age display mechanism operates synchronously with time, thus accurately displaying the moon's position and age. A power integration mechanism combines two power sources and outputs them as a single power source to the lunar wheel or lunar shadow wheel. Therefore, the moon's position or age can be accurately displayed synchronously with time.
[0017] Therefore, it is possible to provide clocks with a month age display that can improve the visibility of month age information.
[0018] In addition, the aforementioned power integration mechanism is a planetary gear mechanism.
[0019] Based on this configuration, the integrated power function based on the power integration mechanism can be achieved in a small space. Therefore, it is particularly suitable for watches and other devices where space is limited. That is, even in a small space, the month information can be accurately displayed.
[0020] In addition, it also has a power distribution mechanism that distributes the power output from the time wheel synchronized with the aforementioned time into the aforementioned two power sources.
[0021] Based on this configuration, the power output from the hour wheel is distributed into two power sources via a power distribution mechanism. These distributed power sources act on the moon wheel and the moon shadow wheel respectively, thereby enabling accurate display of the moon's position and age in sync with the time. Furthermore, the power source for both the moon wheel and the moon shadow wheel is the same as that for the hour wheel, which serves as the power source for the time display. Therefore, both the time display mechanism and the moon age display mechanism can be implemented based on a single power source, thus simplifying the configuration.
[0022] In addition, in the aforementioned lunar age display mechanism, the phase difference between the aforementioned lunar wheel and the aforementioned lunar shadow wheel changes periodically at 120°.
[0023] Based on this design, the age information can be displayed at an appropriate size on the same plane as the dial. Therefore, it can improve both the design and the user's visual recognition.
[0024] In addition, the aforementioned lunar age display mechanism includes: an hour wheel that is synchronized with the aforementioned time; a lunar age feed wheel that distributes the power transmitted from the aforementioned hour wheel into a first power related to the aforementioned lunar wheel, a second power related to the aforementioned lunar shadow wheel, and a third power related to both the aforementioned lunar wheel and the aforementioned lunar shadow wheel; a lunar age transmission wheel that distributes the aforementioned third power transmitted from the aforementioned lunar age feed wheel into a fourth power related to the aforementioned lunar wheel and a fifth power related to the aforementioned lunar shadow wheel; a first power integration mechanism that is input to the aforementioned first power and the aforementioned fourth power and outputs power to the aforementioned lunar wheel; and a second power integration mechanism that is input to the aforementioned second power and the aforementioned fifth power and outputs power to the aforementioned lunar shadow wheel.
[0025] Based on this configuration, the moon wheel moves by power output from the first power integration mechanism. The position of the moon is displayed by the movement of the moon wheel. Meanwhile, the moon shadow wheel moves by power output from the second power integration mechanism. The age of the moon is displayed by the phase difference between the moon wheel and the moon shadow wheel. Therefore, the age of the moon can be accurately displayed synchronously with time using a relatively simple configuration.
[0026] In addition, it also has a solar position display mechanism with a solar wheel that displays the position of the sun in sync with the aforementioned time.
[0027] Based on this configuration, in addition to time and month information, the position of the sun can also be displayed. Therefore, it can improve the display of various information and enhance user convenience.
[0028] [The effects of the invention] According to the present invention, a clock with a month age display mechanism can be provided, which can improve the display of month age information and the operability during correction. Attached Figure Description

[0040] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, in the following description, components having the same or similar functions will be labeled with the same reference numerals. Also, repeated descriptions of these components will sometimes be omitted. In the following description, the side facing the user's arm when the clock 1 with the month display is worn will sometimes be referred to as the back side, and the opposite side as the watch side.

Figure 3 It was omitted. Figure 2 The front view of the moon plate 31, shadow plate 32 and sun plate 37. Figure 4 Viewed from the back Figure 3 Rear view.
[0042] like Figure 1 As shown, clock 1 with a month display is, for example, a wristwatch. Figures 1 to 4As shown, the clock 1 with a moon age display includes an hour display mechanism 2, a moon age display mechanism 3, a sun position display mechanism 4, and a correction mechanism 5. The hour display mechanism 2 has a dial 7 and various hands (not shown) that indicate the hour by pointing to predetermined positions on the dial 7, displaying information related to the hour. The moon age display mechanism 3 has a moon plate 31 and a shadow plate 32 mounted on a base plate 8 on the same plane as the dial 7, displaying information related to the moon, such as the moon's position and its waxing / waning phases (moon age). The sun position display mechanism 4 has a sun plate 37 mounted on the base plate 8 on the same plane as the dial 7, displaying the sun's position. The correction mechanism 5 is configured to correct the moon age information displayed by the moon age display mechanism 3. The various mechanisms will be described in detail below.
[0043] (Time display mechanism) like Figure 1 As shown, the time display mechanism 2 has a dial 7, various hands (hour, minute, second, etc., not shown), and an hour wheel 10 located at the center of the dial 7. On the dial 7, 12-hour scales are depicted at positions corresponding to the various hands. The hour wheel 10 is driven by a movement (not shown) located in the watch 1 with a moon phase display, rotating once every 24 hours. The movement can be, for example, a mechanical automatic or manual winding movement, or a quartz electronic movement, etc. The various hands rotate synchronously with the hour wheel 10 (see also...). Figure 2 For example, the hour hand is connected to the hour wheel 10, which rotates once every 12 hours.
[0044] (Age display mechanism) The month display mechanism 3 includes a month plate 31, a shadow plate 32, and various gear mechanisms that drive the month plate 31 and the shadow plate 32. The month plate 31 and the shadow plate 32 are positioned above the dial 7, with their lower halves overlapping the upper part of the dial 7. The month plate 31 and the shadow plate 32 are positioned further back than the dial 7. Therefore, the upper halves of the month plate 31 and the shadow plate 32 are visually identifiable.
[0045] Figure 5 This is a front view of the moon plate 31 involved in the implementation method. Figure 6 This is a front view of the screen 32 involved in the implementation method.
[0046] like Figure 1 and Figure 5 As shown, the moon plate 31 is formed in the shape of a circular plate with a circular hole 33 of approximately 60° in size relative to the center of rotation. The moon plate 31 represents the position of the moon at a given time. The moon plate 31 is rotated clockwise by various gear mechanisms, which will be described in detail later.
[0047] like Figure 1and Figure 6 As shown, the shadow plate 32 is formed in the shape of a circular plate of the same size as the moon plate 31, and is arranged overlapping the moon plate 31 on its back side. On the shadow plate 32, three circular patterns 35, the same size as the circular holes 33 of the moon plate 31, are depicted at 120° intervals. The three circular patterns 35 are depicted in the same color as the moon plate 31 (e.g., dark blue representing the night sky). The parts of the shadow plate 32 other than the circular patterns 35 are depicted, for example, in the yellow color representing the moon. The age of the moon is indicated by the phase difference between the shadow plate 32 and the moon plate 31. The shadow plate 32 rotates clockwise at a different speed than the moon plate 31 via various gear mechanisms, which will be described in detail later.
[0048] like Figure 3 and Figure 4 As shown, the various gear mechanisms of the lunar age display mechanism 3 are located further back than the dial 7. Specifically, the various gear mechanisms include a moon wheel 24, a moon shadow wheel 25, the aforementioned hour wheel 10, a lunar age feed wheel 11 (the power distribution mechanism of the claim), a lunar age transmission wheel 13, a first lunar age wheel 18, a first planetary gear mechanism 16 (the power integration mechanism and the first power integration mechanism of the claim), a second lunar age wheel 19, a second planetary gear mechanism 17 (the power integration mechanism and the second power integration mechanism of the claim), and first to sixth intermediate wheels 14, 15, 20, 21, 22, and 23.
[0049] Moon wheel 24 is connected to moon plate 31. Therefore, moon plate 31 rotates at the same speed as moon wheel 24. Moon shadow wheel 25 is connected to shadow plate 32. Therefore, shadow plate 32 rotates at the same speed as moon shadow wheel 25. Both moon wheels 24 and moon shadow wheels 25 are driven by a single hour wheel 10. The method of transmitting power from hour wheel 10 to moon wheels 24 and moon shadow wheels 25 will be described below.
[0050] Figure 7 It is along Figure 3 A cross-sectional view of line VII-VII. Figure 8 It is along Figure 4 A cross-sectional view of line VIII-VIII. Figure 9 It is along Figure 3 A cross-sectional view of the IX-IX line.
[0051] like Figure 3 , Figure 4 as well as Figures 7 to 9As shown, the hour wheel 10 is the hour wheel 10 of the aforementioned time display mechanism 2, rotating once every 24 hours. The hour wheel 10 meshes with the lunar age feed wheel 11 disposed above the hour wheel 10, and the rotational power of the hour wheel 10 is transmitted to the lunar age feed wheel 11. The lunar age feed wheel 11 distributes the power transmitted from the hour wheel 10 into a first power P1 associated with the lunar wheel 24, a second power P2 associated with the lunar shadow wheel 25, and a third power P3 associated with both the lunar wheel 24 and the lunar shadow wheel 25 (see reference). Figure 3 Specifically, the monthly feed wheel 11 meshes with the first intermediate wheel 14 and the second intermediate wheel 15. Furthermore, the first intermediate wheel 14 and the second intermediate wheel 15 mesh with the first planetary gear mechanism 16 and the second planetary gear mechanism 17, respectively. The power transmitted from the monthly feed wheel 11 to the first planetary gear mechanism 16 via the first intermediate wheel 14 is the first power P1. The power transmitted from the monthly feed wheel 11 to the second planetary gear mechanism 17 via the second intermediate wheel 15 is the second power P2.
[0052] Furthermore, a C-shaped feeding claw 12 is coaxially arranged on the back side of the feeding wheel 11. The feeding claw 12 rotates integrally with the feeding wheel 11. The feeding claw 12 is formed such that its end abutment portion can elastically deform in the rotational direction relative to the base end connected to the feeding wheel 11. The abutment portion engages with the external teeth of the feeding drive wheel 13, which is coaxial with the hour wheel 10. Therefore, if the feeding wheel 11 rotates by a predetermined angle and the elastic deformation of the abutment portion exceeds a predetermined value, the abutment portion uses elastic force to push against the external teeth of the feeding drive wheel 13, causing the feeding drive wheel 13 to rotate by one tooth. In this embodiment, the external teeth of the feeding drive wheel 13 have 59 teeth. The power transmitted from the feeding wheel 11 to the feeding drive wheel 13 via the feeding claw 12 is a third power P3.
[0053] The lunar drive wheel 13 distributes the third power P3 transmitted from the lunar feed wheel 11 into a fourth power P4 associated with the lunar wheel 24 and a fifth power P5 associated with the lunar shadow wheel 25. Specifically, the lunar drive wheel 13 meshes with the first lunar wheel 18 and the second lunar wheel 19, respectively. The first lunar wheel 18 further meshes with the first planetary gear mechanism 16 via the third intermediate wheel 20. Thus, the power transmitted from the lunar drive wheel 13 to the first planetary gear mechanism 16 via the first lunar wheel 18 and the third intermediate wheel 20 is the fourth power P4. Similarly, the second lunar wheel 19 meshes with the second planetary gear mechanism 17 via the fourth intermediate wheel 21. Thus, the power transmitted from the lunar drive wheel 13 to the second planetary gear mechanism 17 via the second lunar wheel 19 and the fourth intermediate wheel 21 is the fifth power P5.
[0054] The age positioning rod 57 abuts against the age transmission wheel 13. The age positioning rod 57 is a part used to adjust the rotation direction of the age transmission wheel 13. The age positioning rod 57 has an end portion 57a (see reference). Figure 4 The spring portion of the age positioning rod 57 is a free end capable of elastic deformation. The end portion 57a of the spring portion engages with the teeth of the age transmission wheel 13. The age positioning rod 57 adjusts the rotation of the age transmission wheel 13 by engaging its end portion 57a with the teeth of the age transmission wheel 13. Thus, the age transmission wheel 13 can rotate one step per day with an angular pitch (59 / 360°) identical to the pitch angle of the teeth of the age transmission wheel 13.
[0055] Two power inputs are provided to the first planetary gear mechanism 16 (the first power integration mechanism of the claim), namely, the first power P1 transmitted via the lunar feed wheel 11 and the first intermediate wheel 14, and the fourth power P4 transmitted via the lunar transmission wheel 13, the first lunar wheel 18, and the third intermediate wheel 20. The first planetary gear mechanism 16 integrates the two input power inputs (the first power P1 and the fourth power P4) and outputs them as a single power to the lunar wheel 24. Specifically, the first planetary gear mechanism 16 has a sun gear, a plurality of (three in this embodiment) planetary gears, and an internal gear located on the outermost diameter side. The internal gear has internal teeth formed on the inner circumference and external teeth formed on the outer circumference. The first intermediate wheel 14 meshes with the external teeth of the internal gear. Thus, the first power P1 is transmitted to the internal gear.
[0056] On the other hand, the planet carrier, which connects multiple planetary gears, is also equipped with external teeth, and the third intermediate gear 20 meshes with the external teeth of the planet carrier. Therefore, the fourth power P4 is transmitted to the planet carrier, causing it to rotate around the rotational axis of the sun gear. Thus, each of the multiple planetary gears rotates on its own axis while simultaneously revolving around the rotational axis of the sun gear.
[0057] As the internal gear and the sun gear rotate, the sun gear rotates at a predetermined speed. The sun gear meshes with the moon gear 24 via the fifth intermediate gear 22. Thus, the first planetary gear mechanism 16 functions as a power integration mechanism associated with the moon gear 24, receiving inputs of the first power P1 and the fourth power P4 and outputting a sixth power P6 to the moon gear 24.
[0058] The second power P2, transmitted via the lunar feed wheel 11 and the second intermediate wheel 15, and the fifth power P5, transmitted via the lunar transmission wheel 13, the second lunar wheel 19, and the fourth intermediate wheel 21, are input to the second planetary gear mechanism 17 (the second power integration mechanism of the claim). The second planetary gear mechanism 17 integrates the two input powers (the second power P2 and the fifth power P5) and outputs them as a single power to the lunar shadow wheel 25. Specifically, the second planetary gear mechanism 17 has a sun gear, a plurality of (in this embodiment, three) planetary gears, and an internal gear located on the outermost diameter side. The internal gear has internal teeth formed on its inner circumference and external teeth formed on its outer circumference. The second intermediate wheel 15 meshes with the external teeth of the internal gear. Thus, the second power P2 is transmitted to the internal gear.
[0059] On the other hand, the planet carrier, which connects multiple planetary gears, is also equipped with external teeth, and the fourth intermediate gear 21 meshes with the external teeth of the planet carrier. Therefore, the fifth power P5 is transmitted to the planet carrier, causing it to rotate around the rotational axis of the sun gear. Thus, each of the multiple planetary gears rotates on its own axis while simultaneously revolving around the rotational axis of the sun gear.
[0060] As the internal gear and the sun gear rotate, the sun gear rotates at a predetermined speed. The sun gear meshes with the moon wheel 25 via the sixth intermediate gear 23. Thus, the second planetary gear mechanism 17 functions as a power integration mechanism associated with the moon wheel 25, receiving inputs of the second power P2 and the fifth power P5 and outputting a seventh power P7 to the moon wheel 25.
[0061] In this embodiment, the moon wheel 24 and the moon shadow wheel 25 rotate slightly relative to each other with a phase difference of 120° every 29.5 days (which is the lunar cycle). In this embodiment, this phase difference is caused by the different number of teeth on the third intermediate wheel 20 and the fourth intermediate wheel 21. For example, if the rotational speed of the moon wheel 24 is 1 revolution / 1 day when only the first power P1 is input to the first planetary gear mechanism 16, the tooth ratio of each gear is set such that the rotational speed of the moon wheel 24 is -0.0339 revolutions / 1 day when only the fourth power P4 is input to the first planetary gear mechanism 16. Therefore, when both the first power P1 and the fourth power P4 are input to the first planetary gear mechanism 16, the moon wheel 24 rotates at only 0.9661 revolutions / 1 day. If this is converted to a lunar cycle (29.5 days), it becomes 28.5 revolutions / 29.5 days.
[0062] Furthermore, if the rotational speed of the moon wheel 25 is 1 revolution / day when only the second power P2 is input to the second planetary gear mechanism 17, then the gear ratio of each gear is set such that the rotational speed of the moon wheel 25 is -0.0452 revolutions / day when only the fifth power P5 is input to the second planetary gear mechanism 17. Therefore, when both the second power P2 and the fifth power P5 are input to the second planetary gear mechanism 17, the moon wheel 25 rotates at only 0.9548 revolutions / day. If this is converted to a lunar cycle (29.5 days), it becomes 28.167 revolutions / 29.5 days.
[0063] Through the above, a phase difference of 120° is generated between the lunar wheel 24 and the lunar shadow wheel 25 every 29.5 days. Here, as mentioned above, circular patterns 35 are depicted on the shadow plate 32 at intervals of 120°, which are the same as the set phase difference, so as to schematically show the series of lunar phases during the time it takes for the moon to orbit the earth, from full moon through new moon and back to full moon.
[0064] Furthermore, in the above-described embodiment, a phase difference of 120° is generated by making the number of teeth different on the third intermediate gear 20 and the fourth intermediate gear 21, but a phase difference of 120° can also be generated by using the tooth ratio of other gears.
[0065] (Sun position display mechanism) Figure 10 This is a partial cross-sectional view of the clock 1 with a month display according to the embodiment.
[0066] like Figures 1 to 3 as well as Figure 10 As shown, the solar position display mechanism 4 has a solar plate 37 and various gear mechanisms that drive the solar plate 37. The solar plate 37 rotates about a rotation axis coaxial with the rotation center of the moon plate 31. Viewed from the front, the solar plate 37 is positioned to overlap the outer periphery of the moon plate 31 in the radial direction. The solar plate 37 is formed, for example, in a circular plate shape. The solar plate 37 is positioned further back than the dial 7 and further forward than the moon plate 31. The solar plate 37 indicates the position of the sun at any given time. The solar plate 37 rotates clockwise at a rate of 1 revolution per day via the various gear mechanisms of the solar position display mechanism 4, which will be described in detail later.
[0067] The various gear mechanisms of the solar position display mechanism 4 include a sun gear 28, the aforementioned hour gear 10, and a lunar age feed gear 11. The sun gear 28 is connected to the solar plate 37. Therefore, the solar plate 37 rotates at the same speed as the sun gear 28. The sun gear 28 is driven to rotate by the hour gear 10. The method of transmitting power from the hour gear 10 to the sun gear 28 will be described below.
[0068] As described above, the rotational power of the hour wheel 10 is transmitted to the moon feed wheel 11. The moon feed wheel 11 further engages with the sun wheel 28, which is positioned higher than the moon feed wheel 11. Thus, the rotational power of the hour wheel 10 is transmitted to the sun wheel 28 via the moon feed wheel 11, and the sun wheel 28 rotates.
[0069] (Revising agency) like Figure 4 As shown, the clock 1 with a moon age display has a correction mechanism 5 that corrects the moon age information displayed in the moon age display mechanism 3. The correction mechanism 5 has a first correction mechanism 51 and a second correction mechanism 52. Both the first correction mechanism 51 and the second correction mechanism 52 cause rotational power to act on the moon wheel 24 and the moon shadow wheel 25, but the input paths of the rotational power are different from each other.
[0070] The first correction mechanism 51 operates the handle 53 (see reference) Figure 1 The first correction mechanism 51 rotates the moon wheel 24 and the moon shadow wheel 25 to correct the moon's age information. The crown 53 normally idles, but is rotated when pulled out to a certain position, thereby rotating various hands and the hour wheel 10 via a movement (not shown) inside the watch. In other words, the first correction mechanism 51 is a mechanism that simultaneously corrects the time display and the moon's age information.
[0071] Figure 11 This is a perspective view illustrating the configuration of the second correction mechanism 52 involved in the implementation method.
[0072] The second correction mechanism 52 has a different input path than the first correction mechanism 51, and corrects the month age information more quickly and independently than the first correction mechanism 51. For example... Figure 4 and Figure 11 As shown, the second correction mechanism 52 has two operating sections 55 and 56.
[0073] A pair of operating sections 55 and 56 are provided on the left and right sides of the clock 1 with a month display. In this embodiment, each operating section 55 and 56 is a lever that directly rotates the month transmission wheel 13 by being pushed. The operating sections 55 and 56 have a forward rotation side operating section 55 located on the right side when viewed from the front and a reverse rotation side operating section 56 located on the left side when viewed from the front. The forward rotation side operating section 55 is operated by the user pushing it into the clock, and its end portion 55a located inside the clock engages with the external teeth of the month transmission wheel 13, causing the month transmission wheel 13 to rotate in the positive direction (in the clockwise direction). Figure 11 In the example shown, it rotates clockwise. (Refer to...) Figure 11 (Solid arrow.) Rotation. The forward-rotating side operating unit 55 rotates the month-age transmission wheel 13 by one tooth through a single pushing operation.
[0074] The reverse operation unit 56 is operated by the user pushing it into the watch. The end portion 56a located inside the watch engages with the external teeth of the moon phase transmission wheel 13, causing the moon phase transmission wheel 13 to move in the opposite direction (in the reverse direction). Figure 11 In the example shown, it rotates counterclockwise. (Refer to...) Figure 11 (The dashed arrow.) Rotation. The reverse side operating unit 56 causes the lunar drive wheel 13 to rotate one tooth in the reverse direction by one push operation.
[0075] In addition, each operating part 55, 56 may also be provided with a linkage mechanism for transmitting the user's pushing operation to the age transmission wheel 13, or an elastic component that applies force to the operating parts 55, 56 in the left and right directions when no external force is applied to the operating parts 55, 56.
[0076] (Function, Effect) Next, the function and effect of the clock 1 with the month display will be explained.
[0077] The clock 1 with a moon age display according to this embodiment includes: a dial 7 for displaying the time; a moon age display mechanism 3 having a moon wheel 24 that displays the position of the moon synchronously with the time and a moon shadow wheel 25 that displays the moon age based on the phase difference with the moon wheel 24; and a correction mechanism 5 for correcting the moon age information. The correction mechanism 5 includes: a first correction mechanism 51 that is operated by a handle 53 and corrects the moon age information synchronously with the time; and a second correction mechanism 52 that has a different input path than the first correction mechanism 51 and corrects the moon age information asynchronously with the time and more quickly than the first correction mechanism 51.
[0078] Based on this configuration, a month age display mechanism 3 is provided that operates synchronously with time, thus enabling accurate display of the month's position and age.
[0079] The correction mechanism 5 includes: a first correction mechanism 51, which corrects the gestational age information synchronously with time by operating the handle 53; and a second correction mechanism 52, which has a different input path than the first correction mechanism 51. The second correction mechanism 52 corrects the gestational age information asynchronously with time and more rapidly than the first correction mechanism 51. Thus, the user can use two correction modes corresponding to the correction amount. For example, when the correction amount is small, the gestational age information can be finely corrected by using the first correction mechanism 51 with the handle 53. On the other hand, when the correction amount is large (e.g., in cases where there is a deviation of several days), the second correction mechanism 52 can be used for dynamic correction. Therefore, repeated rotation of the handle 53 is unnecessary, improving operability during correction.
[0080] Therefore, a clock 1 with a month-age display can be provided, which can improve the display of month-age information and the operability during correction.
[0081] The lunar age display mechanism 3 has a lunar age transmission wheel 13 that simultaneously provides driving force to the lunar wheel 24 and the lunar shadow wheel 25, and the second correction mechanism 52 has operating parts 55 and 56 that directly rotate the lunar age transmission wheel 13. With this configuration, by operating the operating parts 55 and 56 of the second correction mechanism 52, the lunar age transmission wheel 13 can be directly rotated. Therefore, lunar age information can be quickly corrected.
[0082] Operating units 55 and 56 are levers that rotate the age transmission wheel 13 by pushing the lever. With this configuration, age information can be easily corrected by pushing the lever. Furthermore, the aforementioned correction function can be achieved with a simple configuration.
[0083] The clock 1 with a moon age display has a dial 7 and a moon age display mechanism 3. The moon age display mechanism 3 has a power integration mechanism (a first planetary gear mechanism 16 and a second planetary gear mechanism 17 in the embodiment). The power integration mechanism is input with two power sources and integrates the two power sources as one power source to output to at least one of the moon wheel 24 and the moon shadow wheel 25.
[0084] Based on this configuration, a lunar age display mechanism 3 operates synchronously with time, thus enabling accurate display of the moon's position and age. The first planetary gear mechanism 16 and the second planetary gear mechanism 17 integrate two power sources and output them as a single power source to the lunar wheel 24 or the lunar shadow wheel 25. Therefore, the moon's position or age can be accurately displayed synchronously with time.
[0085] Therefore, a clock 1 with a month age display is provided, which can improve the display of month age information.
[0086] The power integration mechanism is a planetary gear mechanism. Based on this configuration, the power integration function based on the planetary gear mechanism can be achieved in a small space. Therefore, it is particularly suitable for applications such as watches where space is limited. That is, even in a small space, the month information can be accurately displayed.
[0087] The clock 1 with a moon age display also has a power distribution mechanism (moon age feed wheel 11 in the embodiment) that distributes the power output from the hour wheel 10, which is synchronized with the time, into two power sources. According to this configuration, the power output from the hour wheel 10 is distributed into two power sources via the moon age feed wheel 11. The distributed power acts on the moon wheel 24 and the moon shadow wheel 25 respectively, thereby enabling accurate display of the moon's position and age in sync with the time. Furthermore, the power source for the moon wheel 24 and the moon shadow wheel 25 is the same as that for the hour wheel 10, which serves as the power source for the time display. Therefore, the time display mechanism 2 and the moon age display mechanism 3 can be implemented based on a single power source. Consequently, the configuration can be simplified.
[0088] In the moon phase display mechanism 3, the phase difference between the moon wheel 24 and the moon shadow wheel 25 changes periodically at 120°. Based on this configuration, moon phase information can be displayed at an appropriate size on the same plane as the dial 7. Therefore, it improves both design aesthetics and the user's visual readability.
[0089] The lunar age display mechanism 3 includes an hour wheel 10 synchronized with time, a lunar age feed wheel 11, a lunar age transmission wheel 13, a first power integration mechanism (a first planetary gear mechanism 16 in one embodiment), and a second power integration mechanism (a second planetary gear mechanism 17 in one embodiment). The lunar age feed wheel 11 distributes the power transmitted from the hour wheel 10 into a first power P1 associated with the lunar wheel 24, a second power P2 associated with the lunar shadow wheel 25, and a third power P3 associated with both the lunar wheel 24 and the lunar shadow wheel 25. The lunar age transmission wheel 13 distributes the third power P3 transmitted from the lunar age feed wheel 11 into a fourth power P4 associated with the lunar wheel 24 and a fifth power P5 associated with the lunar shadow wheel 25. The first planetary gear mechanism 16 is input with the first power P1 and the fourth power P4 and outputs a sixth power P6 to the lunar wheel 24. The second planetary gear mechanism 17 is input with the second power P2 and the fifth power P5 and outputs a seventh power P7 to the lunar shadow wheel 25. According to this configuration, the lunar wheel 24 operates by the sixth power P6 output from the first planetary gear mechanism 16. The position of the moon is displayed by the movement of the moon wheel 24. Additionally, the moon shadow wheel 25 is operated by the seventh power P7 output from the second planetary gear mechanism 17. The age of the moon is displayed by the phase difference between the moon wheel 24 and the moon shadow wheel 25. Therefore, the age of the moon can be accurately displayed synchronously with time using a relatively simple configuration.
[0090] The clock 1 with a moon phase display also includes a sun position display mechanism 4 with a sun wheel 28 that displays the sun's position in sync with the time. With this configuration, in addition to the time and moon phase information, the sun's position can also be displayed. Therefore, the display of various information is improved, enhancing user convenience.
[0091] Furthermore, the scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the present invention.
[0092] For example, in the above embodiment, the phase difference between the moon plate 31 and the shadow plate 32 is 120°, but it is not limited to this. For example, the gear ratio of the gear train can also be set such that the phase difference between the moon plate 31 and the shadow plate 32 is 90° or 180°, etc. When the phase difference is 90°, four circular patterns 35 can be drawn on the shadow plate 32. Similarly, when the phase difference is 180°, two circular patterns 35 can be drawn on the shadow plate 32.
[0093] The operating parts 55 and 56 may not be levers. For example, the operating parts 55 and 56 may be a second handle (not shown) directly connected to the month-age transmission wheel 13 in a rotatable manner.
[0094] In the above embodiments, planetary gear mechanisms 16 and 17 are used as power integration mechanisms, but the method is not limited to this. The power integration mechanism can also be a mechanism other than a planetary gear mechanism. For example, the power integration mechanism can also be a sliding mechanism.
[0095] Furthermore, without departing from the spirit of the present invention, the constituent elements in the above embodiments can be appropriately replaced with well-known constituent elements, and the above embodiments can also be appropriately combined.
