Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an analog world timepiece, and particularly to a specific region (city, country) designated by a conventional format,
For example, the present invention relates to an analog world clock that displays the time of Japan and can read the time of major cities and countries in the world with a time difference so that they can be reset at the same time and that is easy to see and has excellent decorativeness.

[Conventional technology]

Conventional general analog clocks only display the time in a specific area, and the time is displayed by rotating the hour and minute hands clockwise around the center of the fixed dial as the center. ing. However, with the increasing opportunities to see and travel around the world, attention has been paid to a world clock that can display the time of a specific region and the time of major cities in the world with time differences at the same time. There is.

Among such world clocks, Utility Model Application Publication Nos. 16862 and 16865 in 1952 have a world time scale that displays the local time of the world's major cities and countries along the circumference, and the time of the world's major cities and countries. It describes a world clock in which a world city country name display rotating disk displayed in conformity with a place name on the world map centered on the North Pole and a world time display rotating disk making a relative rotary motion relative thereto are added.

[Problems to be solved by the device]

However, the above-mentioned conventional world timepieces have the following drawbacks: (1) Mainly in a specific region (for example, Japan), for example, a timepiece made for Japan Even if it is intended to be used in a world city (eg, New York), it cannot function as a world clock in New York, that is, it cannot change the designated specific area.

This is because the fixed dial has a dual display of the specific regional time display and the world time display fixedly, and it is not possible to readjust the relative relationship between the fixed dial and the rotating display board. This is because the display is fixed.

(2) The displayed world map is unbalanced and very difficult to see.

The problem of the present invention is that any city in the world can be set or adjusted as a world clock whose main purpose is to display the time in a specific city to meet the requirement of (1), and (2 ) It is to provide a world clock that is easy to see and has excellent decoration.

[Means for Solving the Problems]

The present inventor can easily change the specified specific area by enabling the time difference scale position of the world city country name display rotating disk to be adjusted, and the south pole is located around the world city country name display rotating disk. I realized that by displaying a 360-degree world map, it is possible to realize a world clock with a good sense of balance that is easy to see and that is highly decorative.

Thus, the present invention provides: (a) a fixed character having a scale indicating the time of a specific region specified on the 12-hour basis, and having a long hand and a short hand extending radially from the center and rotating clockwise. A disc, and (b) a rotating disc with world city country names that has a time difference scale that displays the time difference between major cities and countries along the circumference and that rotates clockwise with 2RPD (rotation / day), (c) ) Having a world time scale that displays the local time of major cities / countries of the world along the circumference of the circle, and a world time display rotating disc that rotates clockwise at 1 RPD (rotation / day), and the fixed dial, The world city country name rotating disc and the world time display rotating disc are concentrically overlapped, and the minute hand and the minute hand are set to indicate the current time of the area specified on the fixed dial, and the world city country name display. Times The disc and the world time display rotary disk show the time difference scale for representing the designated area on the world city country display rotary disk and the specific world time scale indicating the time of the specific area on the world time display rotary disk indicated by the minute hand. It is set to match the time of the specified specific area on the fixed dial, and when the world city country name rotating disc changes the specified specific area to another area, the time difference scale position is set. The rotation is adjustable so that it can be changed with respect to the fixed dial to represent the time difference of the specific different area to be changed, and the South Pole is located around the world city country display rotary disk.
It provides an analog world clock that displays a 0-degree unfolded world map, which can represent the current time of a specific region, and can easily display the local time in the world in a resettable manner. is there.

Furthermore, it is convenient to display the distinction between day and night on the world time scale of the world time display rotating disk.

[Action]

By rotating the world city country name display rotary disk (M disk) 2RPD and the world time display rotary disk (R disk) 1RPD clockwise, the time of a specific area (Japan) is displayed on the world time difference scale. It matches the time in (Japan), and at the same time, the M board can be adjusted in any city in the world as a world clock whose main purpose is to display the time in that particular city. A world map centered on the South Pole is suitable for a normal clockwise clock, and the map itself is centered on the small Antarctic continent, with continents and islands well dispersed around it, centered on the Arctic continent. It is much easier to see and has excellent decorative properties.

〔Example〕

The world clock of the present invention can be applied to any timepiece such as a table clock, wall clock, wristwatch, pocket watch, and the like.

Here, an analog portable timepiece that is widely used is taken as an example. FIG. 1 shows a display portion of a world clock according to the present invention. Along with the circumference of the fixed dial 1, the time display of a normal analog timepiece is made. That is, there are 60 equal graduations around the fixed dial, and every 5 graduations have a thick graduation. 12 is located on the heavens in the thick graduation and the numbers 1 to 12 are displayed clockwise as the time. There is. By the minute hand 5 that rotates clockwise by 2RPD and the minute hand 3 that rotates clockwise by 1RPH (1 rotation for 1 hour), the designated specific area where this watch is set by the numbers on the fixed dial (Japan Needless to say, the time is displayed. In addition, although not shown, a second hand may be provided.

In the present specification, the "fixed dial" includes not only the one shown in FIG. 1 but also all existing analog clock displays. Numerous display panels are known for decorative purposes and for ease of reading, and their use is not impeded.

The present invention is described below based on this ordinary analog timepiece. By providing the world city country name rotating disk (M disk) 7 and the world time displaying rotating disk (R disk) 9 which rotate in concentric relation, it is possible to eliminate the drawbacks from the past and to flexibly change the specified specific area. It provides a world clock rich in sex.

World city country name display rotating disk (M disk) 7 It has a time difference scale that displays the time difference of the world's major cities and countries along the circumference, and rotates clockwise at 2RPD. M board is
This is to move the time zone position corresponding to a specified specific region to the conventional short hand, that is, the short hand itself. The time of the specified specific area is displayed in the time of the fixed dial pointed to by the time.

A world map based on the time difference centered on the South Pole, a date line can be drawn, and the names of major cities in the world, country names and other related displays (decorations such as national flags) can also be displayed.

A world map centered on the South Pole is suitable for a normal clockwise clock, and the map itself is centered on the small Antarctic continent, with continents and islands well dispersed around it, centered on the Arctic continent. It is much easier to see and has excellent decorative properties.

The disk M also includes a disk-shaped object that becomes a wire work or the like.

World time display rotating disk (R disk) 9 Separate from M disk, it has a world time scale that displays the time of the world's major cities / countries along the circumference, and rotates clockwise at 1RPD, and the circumference of M disk. It is installed so that the world time scale can be seen. Divide the circumference into 24 equal parts (15 degrees), 1 for each half circle
~ 12 or 1 to 24 time numbers (1 to 24 may be omitted by skipping some numbers). Make standard time in each region of the world correspond to the time difference scale.

In addition, it is very convenient to display the day and night separately in black and white or the like. Here, in order to make the division of day and night easy to understand, the semicircle between 6 and 6 is distinguished as a black character (daytime) on a white background, and the remaining semicircle between 6 and 6 is distinguished as a black character and a white character. The day and night partition time is not specified,
For example, it may be divided into 7 to 7, and other light colors and dark colors may be used.

These are the world time scale of the world time display rotating disc 9 and the time difference scale of a specified specific region in the world city country name display rotating disc 7 on the fixed dial 1.
It is set to match the time of the specified specific area indicated by the minute hand. That is, the world time scale (8 on a white background) of the world time display rotary disk 9 is set to match the time (8 am) of the specified specific region (Japan) indicated by the minute hand on the fixed dial 1. Then, the time difference scale of the specified specific region (Japan) on the world city country display rotating disk 7 is set to the display time of the short hand of the specified specific region (8 am
Time) is set.

In the specific example of FIG. 1, the M and R boards are shown as being smaller than the fixed dial, but conversely they are larger than the fixed dial.
That is, it goes without saying that it may be located on the outer periphery thereof.

In the above specific example, the R board is placed between the upper side of the fixed dial and the lower side of the M board, and the time display number of the R board is located inside the peripheral scale of the fixed dial. The board is located.

When using this watch in Japan, set the time difference scale corresponding to the position of Japan on the M board to the direction of the minute hand (current time). This is set by fixing the M board to the short needle shaft by a method such as fitting the M plate into the shaft portion of the short needle during manufacturing and assembly.

In order to change the specific one area to be designated, an expert such as a watchmaker may readjust the fitting position of the M board to the short hand position.

Alternatively, the M board can be rotationally adjusted by a lever from the outside so that a specific designated area can be changed by itself.
This can be easily performed by those skilled in the art by, for example, constructing a double mounting portion including a fixing portion that fixes the M board to the shaft portion of the short needle and a rotating portion that rotatably mounts the M board around the same. Can be configured. Such a mechanism can be easily made in the same manner as the adjustment of the long and short hands.

The minute hand must always point to the position where the fixed dial and the R dial have the same display time. Assuming Japan's time is 8:00 am, the short hand is set to 8:00 on the fixed dial and the long hand is set to heaven's 12 as in a conventional analog clock. In the R dial, 8 in the morning (in this case, 8 in white) matches the fixed dial 8. As for the time of every place in the world other than Japan, the display time on the R board indicated by the corresponding time difference scale on the M board is the time. For example, Honolulu is 1:00 pm and New York is 6:00 pm.

The "minute" time pointed by the hour hand is the same as Japan only in areas with an hour difference. For other areas with a time difference of 30 minutes, the "minute" time pointed by the minute hand is appropriately shifted and read.

When carrying this watch in New York and staying there, for example, readjust the mounting position of the M board to the hour hand or use the external lever to adjust the New York time difference scale of the M board to the New York local time. Align with the fixed dial position. In this way, it is possible to easily change to a world clock that is mainly local.

In short, the M board is to move the time zone position corresponding to the specified specific region to the conventional short hand, that is, the short hand itself, and the time of the specified specific region is the fixed character pointed to by it. The time is displayed on the board. The R board displays the time of the major cities in the world including a specified specific area, and the characters displayed on the R board indicated by the time difference scale corresponding to each area on the M board are the respective times. The time of can be read at a glance. The designated area can be changed by adjusting the time difference scale on the M board.

It is also possible to display a series of code numbers (0 to 23) set with the time difference starting from the date change line. FIG. 2 exemplifies a display unit including an M board for displaying a world map and a code number. The code numbers correspond to the major cities / countries in the world shown in Fig. 1. By the way, code number 0 is Wellington, code number 2 is Canberra, code number 3 is Japan and Seoul, code number 10 is New York and Athens.
.. Code number 22 is Honolulu. FIG. 2 is the same as FIG. 1 in other points.

The time difference is about 1 hour, but there are some areas that are 30 minutes apart, and it is calibrated at a position offset by 7.50 degrees, and other time differences are calibrated as appropriate and correspond to that position. It is better to let them do it.

It is convenient to replace the M board with the time difference scale shifted and displayed during the daylight saving time, and this aspect is also included in the present invention.
