The present invention relates to a universal clock that can easily read the time of a specific region, and at the same time can easily grasp the local time, date, day and night of various cities of the world.

The current time around the world is the Greenwich Observatory in the UK with a longitude of 0 °, the midday sun at noon (12 o'clock in the afternoon), and the local time in a 180 ° longitude. We do (12 pm). In addition, the region with a 180 ° longitude is named as a date change line, and the easternmost part of the date change line around the northern hemisphere is defined as one day earlier than the west.

24 hours is the time when the earth rotates 360 ° with respect to the sun, so 15 ° longitude corresponds to 1 hour. From the point of view of the ground in the northern hemisphere, the sun travels from east to west, so if it is located west of the Greenwich Observatory, it is late as long as its longitude ÷ 15; if it is east, it corresponds to longitude ÷ 15. It is as fast as time to do it.

Due to the development of transportation and communication, the globalization of the world has led to the rapid increase in opportunities to travel around the world and business opportunities with companies located in foreign countries. There is a growing need to know the exact local time.

Due to the demands of the times, various methods of informing the local time of each region of the world are provided.

The simplest of these is to calculate the local time of major cities or regions of the world by referring to the "World Time Table" which lists the time difference between the cities of the world. However, this is not only very troublesome, it is necessary to carry around the world timetable all the time, and if you want to know the local time of the city that is not shown on the world timetable, it is difficult to calculate the time.

In order to solve this problem, many offices that have a lot of communication with foreign countries install separate clocks that display the local time of each city in the world.However, this is not only a space for installation and cost but also available only in the space. There is a restriction to install in space.

There are also products that automatically display the city's local time on the longitude across the baseline when the Earth rotates, but it is also impossible to carry because of its bulkiness.

As an alternative, an electronic clock that stores local time information of major cities of the world has been proposed, although it is possible to know and hold the time of another city without calculation, but it requires a separate operation. In addition, there was a clock that was rotated by combining a disc with the hour hand axis of a conventional clock face and marking a number of regions on the disc, but this had a disadvantage in that the region name that could be displayed on the disc was limited. In addition, even if the local time is known, the length of day and night is not constant because the sunrise and sunset times change with the season and the latitude at which the measurer is located. It was difficult to accurately grasp the local condition with the clock according to the technology.

Meanwhile, in recent decades, the development of electronic communication technology and the spread of personal portable communication devices have been rapidly expanding. Therefore, not the conventionally known mechanical mobile watch (for example, a wristwatch) or a simple electronic mobile watch that displays the hour as a number or an hour hand or minute hand on a liquid crystal. The reality is that digital clocks are required.

In addition, according to diversification and sensitization of human desires, a new concept clock is required to recognize the vision of a specific region as an eye and body, that is, a form that can sense nature as it is, not just as a concept of numbers.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a universal clock that can immediately know the local time of each region of the world without any operation.

In addition, an object of the present invention is to provide a universal clock that can immediately know the state of the day and night by grasping the position of the sun at a glance in each region of the world.

That is, an object of the present invention is to provide a universal clock that can immediately grasp the local time of each region of the world and the global environment at that time.

In order to achieve the above object, the present invention, the south pole or the northern hemisphere of the world map is shown in the center of the south pole or the North Pole and the date change line and day and night, the inner plate of the clock rotates one direction in the same direction as the rotation of the earth per day And, it provides a clock having the essential components of the clock plate is divided into the same angle with respect to the center indicating the time and the hour hand to display the time by rotating once a day.

The clock according to the present invention may simply be a digitized real 'clock' or may be a programmed clock displayed on a mobile phone, a PDA, a PC, or the like. Hereinafter, the term "universal clock" or "clock" as used herein is used in this sense.

In the case of the northern hemisphere of the Republic of Korea, the inner plate and hour hand of the clock rotate in the same direction as the rotation of the earth, i.e. counterclockwise (rotating from the top to the left) in the usual sense. On the contrary, in the southern hemisphere, the inner plate and the hour hand of the clock rotate in the clockwise direction (the direction from the top to the right) in the usual sense.

In the illustrated watch of FIG. 1, the scale is marked separately on the watch's outer plate. However, when the watch's case (the actual case or the virtual case on the screen) is present, the outer plate is to be marked on the outer plate without making a separate outer plate. It may be integrated by marking scales and numbers.

According to the clock of the present invention, not only the local time but also the sunrise and sunset state can be seen at a glance without any operation. Because the Earth's axis of rotation is tilted, the sunrise and sunset times change according to the season, and the latitude of the measurer is also affected, so the length of the day and night is not constant. The conventional clock alone was impossible. According to the clock of the present invention, the sunrise and sunset states are displayed in the shade or color difference on the world map (13). The time has elapsed and you can see at a glance how much time remains until sunset. 1, 2, and 3 are diagrams showing an example of the universal clock of the present invention at the time of the spring equinox, winter solstice, and summer solstice, respectively.

On the other hand, in the universal clock of the present invention, an area located between the Hao (12 pm) scale of the outer plate and the date change line of the inner plate in the counterclockwise direction in the ordinary sense is one day in comparison with the region located outside the area. late.

In addition, the watch of the present invention may further include a minute hand 41 rotates once per hour or a minute hand rotates once per hour and a second hand 42 rotates once per minute. On the outer plate of the clock, a scale indicating time and a scale indicating minutes and seconds may be separately displayed as shown in FIG. 1, but minutes and seconds may be displayed together only with a scale indicating time. In addition, as described above, the outer plate and the case representing minutes and seconds may be integrated into the case.

In addition, the watch of the present invention may be further divided into 24 hours at the same angle with respect to the center of the clock plate is displayed in a different color according to the standard time, and may further include a standard time display unit 20 rotates in the rotation direction of the earth at 24 hours. . At this time, the world map of the inner surface of the watch is divided into the same color as the standard time display unit according to the standard time, so that the local time can be immediately known without additional manipulation without calculating the local time. The standard time display can be located anywhere on the watch face. In FIG. 1, an embodiment of the present invention is located between the inner plate and the outer plate of the watch, but is not limited thereto.

In addition, the clock of the present invention may be set in conjunction with the positioning system to automatically set the local time displayed by the needle by automatically applying the time difference to the standard time. The configuration of such a system is briefly shown in FIG. When the Universal Clock according to the present invention equipped with wired / wireless communication means requests the location information of the current location to the Geographic Information System (GPS), the GPS grasps the location information through various known methods, for example, communication with satellites. Send to watch. The universal clock receiving the location information automatically or manually adjusts the local time. In some cases, the GPS may be manufactured integrally with the universal clock. Such a system is particularly useful when traveling in areas where the standard time is different because the time is automatically displayed by applying the local standard time without any separate operation according to the local time.

In addition, the watch of the present invention may further display information about each region of the world. At this time, the term “worldwide” may be a national concept, or may be a regional or sub-administrative area of a particular country (for example, the United States, US states, counties of the United States, Korea, Do-si in South Korea, city-county in Korea, etc.). ) Or a major city in the world. In the case of this system, various information about each region of the world is embedded in the clock of the present invention or linked to related information on the Internet site which holds (latest) information about each region of the world, so that the position on the world map An indication of the key points to local information, such as the weather and local news. If necessary, it is also possible to link the displayed key information with other information to provide a way to get deeper information. Pointing out the location on the world map may utilize any appropriate input means such as an input method using a keyboard, a touch screen, or a mouse click. Practically, for example, marking all major cities in the northern hemisphere on the inner plate of the clock is spatially impossible. Therefore, it is desirable to apply the "tool tip" technique that is well known in the Internet programming industry. For example, a point is displayed at a corresponding location of a main area of the watch's internal map, and when an indicator such as a cursor moves, the area name is displayed using a balloon help technique for a point within a predetermined distance from the cursor, of which a specific area name When selected, various information of the area is displayed in another balloon form.

This series of steps is schematically illustrated in FIG. For example, when the cursor clicks on a specific point (point or city) of the clock plate, city name information of the corresponding point is extracted by the embedded program and transmitted to the server through the wired / wireless communication network. The server extracts various information of the corresponding city and transmits it to the watch through a wired or wireless communication network. Received various information of the corresponding city is displayed on the watch (screen).

Such a system allows a user to easily obtain various information of a region of interest at any time. In this case, the information to be communicated may be in various categories depending on circumstances.

In addition, the clock of the present invention may further include a display indicating the position of the moon and a display indicating the solution in the part indicating noon. The display unit indicating the position of the moon can be arbitrarily located at an appropriate place on the clock face, and is set to rotate once in about 29.5 days, which is the period of the moon's wear and tear. On the other hand, the position of the moon is a physical position according to natural phenomena, but there is a virtual position that is set to be recognized according to the lunar calendar (陰曆). For example, the actual moon is at a specific location in the field of view of the present invention, but the lunar calendar calculates that the virtual moon is located somewhat before or after it. In addition, lunar dates can be displayed at the same time when indicating the position of the moon. In this case, each culture can be selected to determine the date system used. In other words, the Islamic culture that uses the lunar calendar (Tae 陰曆, Islamic translation, Islamic calendar) and the eastern lunar calendar have different date systems so that different dates can be selected.

In these systems, a rough lunar date can be inferred based on the relative positions of the sun and moon. In other words, when the moon is located at noon, such as the sun, the lunar calendar is 30 days. If the moon is located at the opposite location of the sun, it is 15 days of the full lunar calendar.

The clock of the present invention may be a digital or analog clock. The shape can also be appropriately selected for use in portable, tabletop, wall-mounted or online watches.

In this specification, only the shape structure and the rotational speed of each plate are described, but those skilled in the art will be able to easily implement the universal clock of the present invention with reference to the present specification. That is, the universal clock of the present invention can be made not only by a mechanical method by a combination of a drive device and a tooth having a specific rotation ratio, but also by an electronically operated form, for example, a display device such as a liquid crystal or a monitor. will be.

According to the present invention, it is possible not only to accurately read the local time to which the current one belongs, but also to know the local time of any of several regions at a glance without any separate manipulation.

In addition, the present invention is a 24-hour display system that is commercially available, not only can you immediately determine whether the local time is AM or PM, but also has the function of displaying the day and night fluctuated according to each season or location, so that the local day and night status You can visually check at a glance.

In addition, according to the present invention, the local time of the local area is immediately known by the time of the day or later than the time of the user's residence area by the date change line of the clock plate and the line indicating the hao.

In addition, according to the present invention, it is possible to easily know the current lunar date and the state of the moon, such as the full moon or the year, without searching the calendar from the display unit indicating the position of the moon.

In addition, according to the present invention, it is possible to easily obtain not only a local time but also important information related to a city simply by indicating a location of a city of interest on a world map located on a clock.
