Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clock having a function of displaying the position of a planet at an arbitrary time, and more particularly, to a function of displaying the position of a planet that changes its position in a constellation when viewed from the ground. It is about a planetary display clock.

[0002]

2. Description of the Related Art Displaying the movement of a celestial body on a watch has been attempted for a long time. Particularly, the display of the phase of the moon and the position of a constellation can be realized by a relatively simple mechanism. Has been

[0003] On the other hand, the planet itself orbits only at a constant rotational speed in a substantially circular orbit around the sun at a fixed orbital period, but the planet viewed from the ground is a fixed position in the constellation. Rather than occupying, it changes its position relative to the constellation with seemingly irregular and complex movements that go back and forth as the date and time progress. The planets that are generally visible in the sky are Mercury, Venus, Mars, Jupiter, and Saturn.
In order to display all of them, quintuple display means is required. Due to the complexity of the movement of the planet and the need for multiple display means, there are few examples of clocks that have the function of displaying the position of the planet.

[0004] For example, the invention of Japanese Utility Model Laid-Open No. 2-89394 is as follows.
As shown in FIG. 13, a large number of display elements are arranged on the display unit,
The display element at the center represents the sun 51, and the display elements 53 arranged along four concentric circles 52 drawn around the sun 51.
Displays the location of the planet when lit. The ellipse 54 indicates the approach of the comet. Also,
It also has a current time display means 55. In the example of FIG. 13, the solar system is displayed with the sun at the center. However, similarly, there is a display of the position of a planet viewed from the ground by arranging a large number of display elements.

[0005] Further, in FIG. 14, a ring-shaped picture plate 56 corresponding to the number of planets is provided in a portion corresponding to the dial of the clock, and the position of the planet is displayed by rotating the picture plate 56 in accordance with the revolution period of the planet. Here is an example of a watch that does. In this example, the second hand 60
The center of the earth 58 is fixed at 12 o'clock around the sun picture 57 provided on the shaft portion of, and the picture board 56 provided with the picture 59 of the planet is rotated.

In the display of the solar system centered on the sun as shown in FIG. 13 and FIG. 14, in order to know the position of a planet viewed from the earth, first, the direction of the sun is known, and each planet You will know the position of the planet from the angle of how far you are from the direction of. However, the diameter of the orbit of the actual planet increases exponentially as the outer planet becomes larger, but in the above example, the orbits of the planets are almost equally spaced due to mechanical limitations, and the display section The actual position of the planet is different from the position obtained in. This difference is more pronounced on the outer planet and cannot be ignored,
A curve 61 for compensating for this is drawn on the back of the windshield of the timepiece shown in FIG.

[0007]

However, in the display of the solar system centered on the sun, the display means can be simplified, for example, by rotating the picture plate at a constant speed. , It is difficult to guess where the planet is currently visible.

For example, Mercury and Venus, whose planets orbits are on the inner side of the Earth, do not appear far away from the Sun. Therefore, the position of the planet can be sufficiently estimated from the angle with respect to the Sun. Other planets may appear far away from the sun, and it is difficult to estimate the position of the planet in terms of the angle to the sun after the sun has set.

When displaying a planetary position by illuminating a large number of display elements and illuminating the display elements, the position of the planet as viewed from the ground surface can be displayed. However, the number of display elements that can be actually mounted on a clock is limited. , Only approximate location can be displayed.

[0010] In order to solve these problems, an object of the present invention is to provide a planet display clock that displays the position of a planet as viewed from the ground in an easy-to-understand manner.

[0011]

In order to achieve the above object, a planetary display clock according to the present invention has a dial having a planet window for displaying the positions of planets and constellations, and a dial below the dial. A transparent constellation plate depicting the constellation rotating near the ecliptic, and a plurality of planet plates below the constellation plate, on a ring depicting two rotating planets 180 degrees apart from each other Constellation plate driving means for driving the constellation plate, planetary plate driving means for driving each planetary plate, planetary plate control means for controlling the rotation of the planetary plate, and any time set and timed And a timing means for outputting information.

Further, the constellation plate driving means rotates the constellation plate to display the position of the constellation in the time information. The planetary plate driving means rotates the planetary plate together with the constellation plate by causing the planetary plate to elastically contact the constellation plate by biasing means provided below the planetary plate. The planetary plate drive control means calculates and stores the time of the "going out" of each planet, and applies a signal from the planetary come-and-go time calculating means for detecting coincidence with the time information to the projections provided on each planetary plate. It is characterized in that the rotation and the stop of the planetary plate are controlled by the detaching and detaching means that comes off.

The planet window is a substantially semicircular opening provided on the dial, and the straight line of the opening represents the horizon. Due to the planetary plate driving means and the planetary plate control means, while the time information is the time when the planet is submerged and invisible from the ground, the planetary plate can not see either of the pictures of the two planets drawn on the planetary plate from the window It is characterized in that it is stationary at a position and when the time information becomes the time of the "going out" of the planet, the planet plate is rotated at the same speed as the constellation plate.

Further, since the position of the planet can be known from the position of the picture of the planet in the planet window, the constellation near the ecliptic at the time of the time information and the position of each planet are displayed by the constellation plate. The feature is that the position of the planet can be known from the positional relationship with the constellation.

The pawl axle 42, the operating lever shaft 39c, and the release lever shaft 28b are rotatably supported by the movement 27 by bearings that cannot be seen in the drawing.

The detaching lever 28 fixes the tip of a detaching lever spring 28d to the movement 27 to maintain the posture at rest shown in FIG. When the release lever 28 is in a resting position, the tip of the stop arm 28a is a stop protrusion 24d.
And stops the rotation of the planetary plate 24, which is going to rotate to the left in FIG. 5, following the movement of the constellation plate 22. In addition, when the hanging lever 28 is in a resting posture, the feed arm 28c does not contact the stop protrusion 24d even if the planetary plate 24 rotates.

The operating lever 39 fixes the distal end of the operating lever spring 39d to the movement 27 and maintains the stationary posture shown in FIG. When the operating lever 39 is in a resting posture, the operating arm 39a does not contact the hanging lever 28.

Next, a state in which the planetary plate 24 starts rotating by the movement of the release lever 28 via the operating lever 39 due to the rotation of the ratchet wheel 38 will be described with reference to FIG. FIG. 6 shows the ratchet wheel 3
8 shows a state further rotated clockwise in the figure than the state of FIG.

The pawl 38a rotates while the tip of the receiving arm 39b is hooked, the operating lever 39 rotates counterclockwise in the drawing to change the posture, and the operating arm 39a pushes the unlocking lever 28 to lift the unlocking lever 28. Rotate it counterclockwise. When the release lever 28 rotates counterclockwise in FIG.
a is disengaged from the stop projection 24d and the feed arm 28c

FIG. 7 shows a state in which the ratchet wheel 38 is rotated counterclockwise in the figure from the state of FIG. 6 to return the operating lever 39 and the release lever 28 to the resting posture. Since the hanging lever 28 pushes the planetary plate 24 slightly forward, even if the operating lever 39 and the hanging lever 28 are returned to the resting state immediately from the state of FIG.
The d does not get caught on the retaining arm 28a. In order to perform this operation smoothly, the retaining arm 28a is provided with a spring property.

Next, the operation of selecting and operating an arbitrary one of the six release levers 28 will be described. First, since the ratchet wheel 38 is attached to the ratchet axle 42 while changing the angle of each pawl 38a, all the operating levers 39 and the releasing levers 28 are simultaneously released by the clockwise rotation of the pawl wheel 38 in the drawing. Does not work.

For example, in FIG. 4, in the second operating lever 39 and the ratchet wheel 38 from the front, the ratchet wheel 3
The claw 38a of FIG. 8 is touching and is in the state immediately before the operation as shown in FIG. 5, but the other five hook wheels 38 do not touch the operation lever 39 because the angle of the claw 38a is changed. When the ratchet axle 42 rotates clockwise about 15 degrees from this state, only the second operating lever 39 from the near side is operated by the ratchet wheel 38 as shown in FIG.
Move the third release lever 28, but do not move the other five actuation levers 39.

Next, it is considered that only the first operation lever 39 and the release lever 28 are operated. By rotating the pawl axle 42 to the predetermined angle counterclockwise in the drawing, an arbitrary one operating lever 39 is selected from the six operating levers 39, and then the pawl axle 42 is rotated clockwise in the drawing. Then, the operation lever 39 is operated.

For example, in order to operate the frontmost operating lever 39 from the state shown in FIG. 4, the pawl axle 42 is rotated 300 degrees counterclockwise in the drawing, and then the pawl axle 42 is turned clockwise in the drawing. Turn 15 degrees.

In FIG. 8, the ratchet wheel 38 is rotating counterclockwise in the direction of the arrow, and the receiving arm 39b reaches the tip of the pawl 38a along the gentle surface of the pawl 38a, and the operating lever 39 is operated. Since the lever 39 is rotated clockwise in the figure,
The counterclockwise rotation of the ratchet wheel 38 does not operate the release lever 28.

In order for the planetary display clock according to the present invention to correctly display the position of the planet, the constellation plate 22 which is a mechanical component of the constellation plate driving means 20 and the planetary plate control means 16 is required.
The position of the planetary plate 24, the ratchet wheel 38, and the release lever 28 are determined by the constellation plate driving means 20 and the planetary plate control means 16.
Must match the position stored by the electronic circuit component.

The origin setting means 19 adjusts the position of the mechanical component to a predetermined reference position in order to match the position of the mechanical component with that stored in the electronic circuit component. And a procedure for adjusting the positions of the constellation plate 22, the planetary plate 24, the ratchet wheel 38, and the release lever 28 stored in the electronic circuit components to the value indicating the reference position, and this procedure will be described. .

The constellation plate 22 is defined as a reference position of the constellation plate 22 at a position where the red-diameter scale 0 degrees provided as a guide to know the position of the planet coincides with the 12 o'clock direction of the clock. Planet plate 24 is a planet window 25a
The position where neither of the pictures 24a and 24b of the planet is visible from is set as the reference position of the planet plate 24. Hanging lever 2
Reference numeral 8 denotes a lever 2 for releasing a posture at rest as shown in FIG.
8 is the reference position.

In FIG. 9, reference numeral 37a denotes a mark indicating the origin position written on the outer periphery of the origin confirmation wheel 37 by engraving and using paint. The reference position of the ratchet wheel 38 is a position where the pawl 38a of the foremost ratchet wheel 38 in FIG. 4 is right above, and when the ratchet wheel 38 is at the reference position, a mark 37a comes to the position of the origin confirmation window 25c. The origin confirmation wheel 37 is fixed to the pawl axle 42 as described above.

Next, the operation of setting the reference position by the origin setting means 19 will be described. Depending on the position of the ratchet wheel 38, there is a possibility that any one of the release levers 28 may be in the operating state. However, by turning the pawl axle 60 counterclockwise in FIG. Can be returned to the posture at rest.

The planet plate 24 is provided with all of the release levers 2.
When 8 is in the resting position, the constellation plate 25 is rotated clockwise by 1
When the planet plates 24 are rotated by 80 degrees or more, when the pictures 24a and 24b of the planets disappear from the planet window 25a, the stop projections 24d are caught on the stop arms 28a and stopped. Painting of the Planet 24
a and 24b are invisible from the planet window 25a.

The constellation plate 22 rotates the constellation plate 22 by operating a button, and adjusts the right ascension of 0 ° on the scale visually drawn on the constellation plate 22 to the 12 o'clock position. Also, the ratchet wheel 38 is
By operating the button, the pawl axle 42 is rotated counterclockwise in FIG. 4, and the position of the mark 37a is visually aligned with the origin confirmation window 25c.

Since the position and state of the mechanical component become the reference position by the above operation, the stored position of the electronic circuit component is adjusted to a value indicating the reference position by operating a button. The position or state of the mechanical component matches the value stored in the electronic circuit component.

Next, the planet plate 24 of the planetary display clock according to the present invention is composed of two planet pictures 24a separated from each other by 180 degrees.
The operation of displaying the movement of the planets in FIGS. 24 and 24b will be described with reference to the outermost planet plate 24, the Saturn plate 35 as a representative.

In FIG. 11, the picture 24a of the planet becomes visible from the planet window 25a by the rotation of the planet plate 24, and displays the position of the planet. At this time, another planet picture 24b is a planet picture 24a
And 180 degrees apart, and remains hidden under the dial 25.

In FIG. 12, when the planet plate 24 further rotates and the picture 24a of the planet reaches the horizontal portion on the right side of the planet window 25a and disappears from the planet window, the rotation of the planet plate 24 is stopped by the planet plate control means 16. To indicate that the planet has died. On the back side of the planet plate 24, there is provided another set of the hooking / unlocking means 18, the hooking projection 24d for hooking / removing, and the feeding dent 24e at a position 180 degrees away from each other.
The rotation of the planetary plate 24 can be stopped at the position where the sun sinks.

When the picture 24a of the planet is submerged, the picture 24b of the other planet is located on the left side of the planet window 25a.
When the time information 15 becomes the time of the next "going out" of the planet, the picture 24b of the planet can be immediately shown.

The planet does not always appear at the same position with respect to the constellation, but it appears that the position of the planet gradually changes within the constellation as the date and time progress. This indicates that the time of the planet's "departure" is not constant but changes with the progress of the date and time.

In the planetary display clock according to the present invention, the planet plate 24
In addition, two pictures 24a and 24b of two planets 180 degrees apart from each other are provided, so when one picture 24a of the planet is submerged, the picture 24b of the other planet is already on the left side of the planet window 25a and the next When the time of the planet's “out” comes, the picture 24b of the planet can be shown immediately, so even if the time of the planet's “out” gradually advances with the progress of the date and time, At the time of “exit”, the picture 24b of the planet can be shown in the planet window 25a to display the position of the planet.

Next, an operation for displaying the position of a planet at an arbitrary time in the planetary display clock according to the present invention will be described. First, while confirming the time by means of the arbitrary time display means 14, a desired arbitrary time is set to the timekeeping means 13 by the arbitrary time setting means 12 by operating a button. Then, automatically, first, all the release levers 2
8 takes a resting posture to stop the planet plate 24, the constellation plate 22 rotates clockwise from the current position by 180 degrees, so that the pictures 24a or 24b of all the planets cannot be seen from the planet window 25a, and then The time 12 hours before the time set by the arbitrary time setting means 12 is output from the clocking means 13 as time information 15, and the constellation plate driving means 20 obtains the position of the constellation plate 22 corresponding to the time information 15 and obtains the constellation plate. Rotate 22 at fast forward.

Next, the time measuring means 13 outputs the time of the set time.
The time information 15 from the time before the time to the set time is 1
Output in fast forwards every minute. In accordance with the time information 15 output by this fast forward, the constellation plate driving means 20
When the time information 15 coincides with the time of "going out" of the planet, the planetary plate control means 16 releases the locking of the corresponding planetary plate 24 and rotates the planetary plate 24 together with the constellation plate. .

When the time information 15 becomes the date and time set by the arbitrary time setting means 12, the position of the planet at the set time is displayed in the planet window 25a. After this, timekeeping means 1
3 outputs the time information 15 clocked by the clock signal 26 from the oscillation circuit 10, so that the display position of the planet moves every moment. Therefore, by setting the current time as an arbitrary time, this planet display clock displays the current planet position.
