Description

Seasonal From Which A Season Can Be Determined}

The present invention is a watch capable of grasping the seasons, and more specifically, by adding a seasonal plate that rotates 360.99 ° in 24 hours to a watch having a market that rotates once per 24 hours, and the seasonal (months, 24 seasons), It's about a clock that lets you instantly know the relative altitude of the Sun.

The global trend is to use Western-centralized and modernized year-date systems, ie, Gregorian calendar. However, dividing 365 days into one year, one year into twelve months, and each month into 28 to 31 days shows that the lift based on the Earth's cycle of orbit around the sun does not reflect the natural seasonal phenomena of the earth. There are disadvantages. For example, it is easy to remember and find out what month it is by the Gregorian calendar, but what season is it, which of the 28 astronomical numbers in the Asian astronomy, or which of the zodiac signs in the Western constellations? Whether it is in the constellation is not known at all by the calendar. To find this more specialized information, you should consult a full text book or a special calendar.

Therefore, a simple device that can recognize the earth's time cycle by various standards such as 24 seasons, 28 counts, or zodiac sign, rather than the solar calendar, is necessary for professional use, but it is not only about the longing for the various knowledges of the modern people, Its importance is also increasing as a perfumery accessory.

The present invention was devised to solve the need for a specific seasonal cycle as described above, and a clock plate combining a commercial plate (1) rotated once every 24 hours and a seasonal plate (2) divided on the basis of various time periods. By using, we want to provide a clock that can identify the unusual seasonal point in time.

BRIEF DESCRIPTION OF THE DRAWINGS An example which shows the combination of the watch plate of the watch of this invention.

Figure 2 is another example showing the combination of the clock face of the watch of the present invention.

***** Explanation of Drawings *****

1. Commercial 2. Seasonal 3. Separation

4. Visual Reading 5. Separate Edition

The clock of the present invention for achieving the above object is a circular commercial (1) which rotates once every 24 hours, and the division is marked with a 24-division scale at the same angle with respect to the center; A circular seasonal plate (2) rotated 360.99 ° in 24 hours in the same direction as the commercially available plate (1), the scale of which is divided at a predetermined angle by a predetermined criterion being displayed; It is a rotating clock (FIG. 1).

The clock of the present invention may be added with a circular divider 3 which is rotated once per hour and whose division is marked with a 12 division scale at the same angle with respect to the center.

The watch of the present invention is provided with a clock hand such as hour hand, minute hand, and second hand, and the clock plate is divided into 12 parts, so that the hour hand is rotated two times a day, the minute hand is 24 revolutions per hour, and the second hand is rotated once per minute. Unlike a conventional clock that displays a time reading line 4 composed of a visual indicator line or an indication mark fixed separately from each plate, instead of a clock, the time reading line 4 is usually in the 0-o'clock direction (the clock of the present invention is indicated). Rather than the direction of the clock, the direction indicated by the 0 o'clock of a daily two-turn clock, the uppermost part when looking at the clock) is displayed, and the market (1) divided into 24 is displayed on the day instead of rotating the clock hands. The hourly separation of the specific time is displayed in one rotation, and the separation plate 3 divided into twelve displays the minute of the specific time by one rotation per hour. At this time, the division lines divided into subdivisions as necessary may be displayed between the division displays to determine the minutes of a specific time or to accurately read the minutes at the commercial market 1 alone.

In the present specification, 'clockwise' and 'counterclockwise' respectively mean a direction in which a clock hand rotates in a conventional clock and vice versa.

Between each divisional display or divisional display of the commercially available 1 of the present invention, a number from 0 to 24, or 0 to 12 can be displayed continuously from 0 to 12, and 0 to 12 can be displayed to represent the afternoon. You can display 1 to 11 in different colors. You can also determine the altitude of the sun at a specific time by displaying a red dot instead of the number 12. The commercial 1 can be rotated continuously in an analog manner or rotated one space per hour in a digital manner. In each division display of the separation plate 3 of the present invention, the number of 0, 10, 20, ..., 50 or the number of 0, 15, 30, 45 may be displayed for convenience.

The rotational direction of the commercial plate 1 and the separator plate 3 of the present invention should be the same. When each plate rotates counterclockwise, the order of the displayed number of hours and minutes is clockwise, and when each plate rotates clockwise, And the display order of minutes is shown counterclockwise. Therefore, in the present invention, the commercially available plate 1 and the separator plate 3 can be rotated clockwise or counterclockwise at the same time. In addition, the commercially available 1 of the present invention may be larger or smaller than the separation plate 3.

In the clock according to the present invention, the seasonal plate 2 rotates 360.99 ° in 24 hours in the same direction as the commercial plate 1, which is 365 days while the commercial plate 1 and the seasonal plate 2 rotate in the same direction. It is a speed at which the seasonal plate 2 is rotated with respect to the commercial plate 1 while the commercial plate 1 rotates 365. As a result, the seasonal plate 2 is further rotated with respect to the commercial plate 1 by an angle corresponding to one day while the commercial plate 1 is rotated one time, that is, one day passes.

In the clock according to the present invention, the scale of the season plate 2 is the angle by the ratio of the number of days belonging to each month of the Gregorian calendar, the angle formed by 28 numbers around the celestial pole, or the angle formed by the zodiac. It can be divided into

When displaying the lunar month on the seasonal version (2), the number of each month is displayed between the scale and the scale, and the angle between the scale and the center of the seasonal version (2) is [the number of days in the month × 360 ° ÷ 365 ].

Number 28 is the name of the Oriental astronomical map of the constellation clusters around the ecliptic celestial path through the sun, and is distributed in various positions and angles around the North Pole in the celestial sphere. The zodiac is derived from Western astronomy and is a constellation that is divided into 12 equal parts of the ecliptic from the vernal equinox. It is composed of infantry palace and twin arch. The zodiac is also called sheep, bulls, twins, crabs, lions, maidens, libra, scorpions, archers, goats, water bottles, and pisces.

In addition, the watch according to the present invention rotates 360.99 ° in 24 hours in the same direction as the commercial (1) and seasonal plates (2) in the center thereof, and may be provided with a star plate (5) drawn with major constellations near the North Pole. (FIG. 2).

At this time, the rotational speed of the separate plate 5 is derived by the following calculation.

During the day, the Earth revolves around 0.99 ° (= 360 ° ÷ 365 days). In the meantime, the Earth rotates once, but it must rotate about 0.99 ° further in the center of the sun to rotate once. Therefore, the time for one rotation of a star is about 3.9 minutes (= 0.99 ° × 60 minutes ÷ 15 °) faster than the time for one rotation of the sun. Therefore, the night sky swells about 3.9 minutes earlier every day and loses early. By this calculation, the rotational speed of the separate plate 5 is set to 360.99 ° rotation in 24 hours.

Therefore, when the user sees the watch of the present invention, the time at that time is determined by the commercial (1), the separation (3), and the time indicator, and then by the display of the seasonal edition (2) corresponding to the noon of the commercial (1). By the asterisk 5, the major constellations of the celestial north pole at that time can be easily grasped.

Each plate in the present invention as described above can be determined in a variety of sizes for convenience. For example, it can also be made small in order of the commercial 1, the separation 3, and the seasonal 2, and can also change the order. However, the separate plate 5 should always be installed in the center of the clock plate.

In this specification, only the shape structure and rotation speed of each plate are described, but a person skilled in the art to which the present invention pertains may easily implement the watch of the present invention with reference to the present specification. That is, the clock of the present invention may be made not only by a mechanical method by a combination of a driving device and a tooth having a specific rotation ratio, but also by a display device such as a liquid crystal or a monitor by an electronic method.

The watch of the present invention includes a commercial plate (1) that rotates once per 24 hours, a seasonal plate (2) and a separate plate (5) that rotate at an appropriate speed, so that the state of the moon, the 24 seasons, and the current sun are relative to each other. Easily identify altitude and constellation locations.
