However, a 24-hour clock such as Patent Document 1 and a world time difference quick watch such as Patent Document 2 are inconvenient because it is not possible to know the current time in the world easily at a glance regardless of the northern or southern hemisphere. The technical problem of the present invention is to pay attention to such a problem and to realize a convenient double 24-hour clock that can easily and easily know the current time in the world regardless of the northern or southern hemisphere. is there.

Claim 1 is a double 24-hour clock having a dial with a scale as a 24-hour clock and a 24-hour rotating body with a single hand indicating time or a display corresponding to 24 hands or 24 hands. ,
If the front and back watches and the back watch and / or one watch and the other watch have different hemispheres or the same hemisphere, they have a pair of hands. It is a double 24-hour clock characterized by being.
The hand for displaying the time may be a single hand or 24 hands. Alternatively, a display corresponding to 24 hands may be used. In the case of a display corresponding to 24 stitches or 24 stitches, it is better to display on a disc. Then, the timepiece is provided on both the front and back surfaces, and the front timepiece and the backside timepiece display different hemispheres or the same hemisphere. Different hemispheres are the northern and southern hemispheres, and the same hemisphere is only the northern or southern hemisphere.

According to a second aspect of the present invention, when the 24-hour timepiece is provided on both the front and back surfaces and the hands rotate reversely, the front rotating shaft and the back rotating shaft are shared. The double 24-hour clock according to Item 1.
That is, one of the front and back sides has a configuration that does not require a drive source.

According to a third aspect of the present invention, the front and back surfaces and / or the pair of timepieces have a drive source only on one side, and the other does not have the drive source, and the single hand or 24 via a gear, a timing belt, or a chain. The double 24-hour timepiece according to claim 1 or 2, wherein the hand display is configured to rotate. When one gear is interposed, reverse rotation is possible, and when a timing belt or chain is interposed, the same rotation is achieved.

4. A 24-hour timepiece according to any one of claims 1 to 3, wherein an analog display is provided by the single-needle or 24-needle type rotating body, and at least a minute is a digital display. is there. Therefore, analog display and digital display are used together.

As in claim 1, when there are a pair of different 24-hour clocks on the same surface such as both front and back, left and right, top and bottom, and when displaying the time of the northern and southern hemispheres, only the operation of inverting the front and back or the same By simply comparing a pair of 24-hour clocks on the surface, you can know the time of the entire earth. In addition, when displaying only the northern hemisphere or only the southern hemisphere, one hand can be a single hand and the other hand can be provided with a display corresponding to 24 hands or 24 hands. .

If the front and back needles rotate in the reverse direction as in claim 2, the front rotary shaft and the reverse rotary shaft are shared, so one of them does not require a drive source and is inexpensive. Can be realized.

Since the drive source is provided only on one side and the other does not have the drive source as in claim 3 and the single hand or 24-hand display is operated via a gear, a timing belt, or a chain, the hemispheres having different timepieces When displaying the same hemisphere or a single hemisphere, a single drive source is sufficient, which can be realized at low cost.

Since the analog display is performed by the single needle or the 24-needle type rotating body and the minute is the digital display as in the fourth aspect, the display of the single needle or the 24-needle type dial is simplified. Since the minute hand and the second hand are used in combination as in Patent Documents 1 and 2, the 24-hour display looks complicated and makes it difficult to get used to. Therefore, although it is difficult to spread, it becomes easier to see if it is simplified as in the present invention.
When you get used to the 24-hour display, I think it would be fun to bring out a new product that also uses a minute hand and a second hand.

It is the front view and back view which show embodiment of a single hand type front and back timepiece. It is the front view and back view which show embodiment of a 24-hand type front and back timepiece. It is a front view which shows embodiment of the right-and-left type | mold timepiece provided with only a single hand type | mold or only a 24 needle type | mold. It is a front view which shows embodiment of the right-and-left type | mold timepiece provided with both the single needle | hook type | mold and 24 needle | hook type | molds.

Next, an embodiment of how the double 24-hour clock according to the present invention is practically described will be described in detail. 1 and 2 are a front view and a rear view showing an embodiment of a front and back mold, and FIG. 3 and subsequent figures are front views showing a left and right mold embodiment. First, the single needle type shown in FIG. 1 will be described.
The single-needle type is an embodiment in which a person who looks at or uses a 24-hour clock (displayed with a face) is regarded as a single hand 1, 1 ', and the character displayed on the dial 2, 2' is the earth The time corresponding to the longitude of is displayed. The dial 2 is regarded as a person in the northern hemisphere, the single hand 1 is regarded as a person in the northern hemisphere, the dial 2 'is regarded as a person in the southern hemisphere, and the single hand 1' is regarded as a person in the southern hemisphere.

Usually, the sun is positioned directly above at 12 o'clock in the daytime, so the sun S is displayed as well as 12 o'clock on the top. 0 o'clock is arranged directly below, and the interval between 0 o'clock and 12 o'clock is divided into 12 equal parts.
FIG. 1 (1) showing the state seen from the front shows the state of the northern hemisphere seen from the north pole, so the center 3 shows the northern hemisphere and the north pole, and the single needle 1 indicating the person in the southern hemisphere rotates counterclockwise. This is indicated by an arrow. Therefore, the display of the dial 2 is equally divided counterclockwise from 0 o'clock to 24 o'clock.
Fig. 1 (2) showing the state seen from the back side shows the state of the Southern Hemisphere seen from the South Pole, so the center 3 shows the Southern Hemisphere and the South Pole, and the single needle 1 'showing the person in the Southern Hemisphere rotates clockwise. This is indicated by an arrow. Therefore, the display of the dial 2 is equally divided clockwise from 0 o'clock to 24 o'clock.

Such a movement of the single needle 1, 1 ′ can be driven independently by providing an independent drive source, but in the illustrated embodiment, a drive source is provided on one side, for example, the northern hemisphere side, The rotation axis of the single needle 1 and the rotation axis of the single needle 1 ′ pointing to the dial on the back side indicating the southern hemisphere may be shared, and the driving source on the southern hemisphere side may be omitted.
Now, in such a configuration, assuming that the northern hemisphere is approximately 15:30 as shown in FIG. 1 (1), the southern hemisphere also shows approximately 15:30 as shown in FIG. 1 (2). To be precise, as shown at the bottom of each figure, it can be seen from the digital clock that it is 15:29:30.
By emphasizing the relationship between the earth and its sun, analog features are also emphasized. As a result, the earth can be recognized as a life form, and a new approach to environmental issues arises.

In the single-hand type clock as described above, the relationship between the single hand and the northern and southern hemispheres and the sun can be understood, but the state of the entire earth cannot be known. Therefore, a 24-needle type was invented as shown in FIG. This 24-needle type expression may actually form a disk 4 in which 24 needles are radially pointed to indicate a pointed state like a needle, or 24 needles are radially pointed. You may provide the disk which drew the figure. In short, it is sufficient to have a display corresponding to 24 hands.
And in order to display the main country which shows the longitude of 24, as shown in FIG. 2, the national flag of the country is illustrated on the disk inside the pointed needle. A national flag may be displayed on a pointed needle. A country name or its abbreviation may be described instead of the national flag.

Thus, when using a 24-hand type front and back clock with 24 hands instead of a single hand, I (user) who is a Japanese and South Korea with the same longitude are 12:30 (noon) If so, we can see that it is 0:30 am in Brazil, just opposite the earth.
In FIG. 2 (1) showing the Northern Hemisphere, if London is 3:30 (am), it can be seen that it is 15:30 in Auckland, New Zealand, just opposite the earth.
In the case of Fig. 2 (2), which shows the southern hemisphere, the case of Fig. 1 (2) is exactly the right-handed direction, so if London is 3:30 (am), New Zealand is located just opposite the Earth. You can see that it's 15:30 in Auckland.
In the case of FIG. 2 as well, the 24-needle disk rotates reversely on the front and back sides, so the rotation axis can be shared.

In addition, when I entered the country name with 24 hands clockwise, I felt doubt because China came to the left of Japan and realized that it was related to the country (longitude) as seen from the South Pole.
However, since it is the country's position as seen from the Antarctic side, it is good to go clockwise.
However, there are some people who are comfortable with the time expression in the counterclockwise direction, so I think it should be useful for those people. I think it would be better if you look at the one that you like, that is, the one that looks good.

FIG. 3 (1) shows an example of a configuration arranged on the left and right instead of the single needle type arranged on the front and back in FIG. In the figure, the left side represents the northern hemisphere, and the right side represents the southern hemisphere. Therefore, there is an advantage that the difference between the northern hemisphere side and the southern hemisphere side can be compared at a glance.
FIG. 3 (2) is an example of a configuration arranged on the left and right instead of the 24-needle type arranged on the front and back in FIG. Since the left side represents the northern hemisphere and the right side represents the southern hemisphere in the figure, there is an advantage that the difference between the northern hemisphere side and the southern hemisphere side can be compared at a glance.

In FIG. 3, FIG. 3 (1) is a single needle type on both the left and right sides, and FIG. 3 (2) is a 24 needle type on both the left and right sides. On the other hand, in FIG. 4, although it is a left-right type, in FIG. 4 (1), the left side is a single needle type and the right side is a 24-needle type. Moreover, both indicate the Southern Hemisphere.
In FIG. 4 (2), the left side is a single needle type and the right side is a 24 needle type, both of which show the northern hemisphere. Therefore, one and the other of the pair have a difference between the southern hemisphere and the northern hemisphere, and one and the other of the pair have a difference between a single needle type and a 24-needle type.
Also in the case of the left and right type as shown in FIG. 3 and below, it is not necessary to provide a drive source on each of the left and right sides. That is, if it is necessary to drive in the same direction, a timing belt or a chain may be interposed, and if it is desired to reversely rotate, a gear may be interposed.
In addition, when interposing a gear, a timing belt, or a chain, it is good to interpose between each rotating shaft or between the drive bodies of a rotating shaft.

3 and 4 are examples arranged on the left and right, but a pair of different 24-hour clocks may be arranged vertically and diagonally, and the directions of arranging them on the same plane are arbitrary.
Moreover, when the same surface is insufficient, both front and back surfaces may be used together. That is, when the front and back molds of FIGS. 1 and 2 and the same surface mold of FIGS. 3 and 4 are used in combination, more different 24-hour clocks having different configurations can be arranged.
1 and 2 are limited to 0 degrees and 120 degrees because they are front and back, and the embodiments of FIGS. 3 and 4 are limited to 0 degrees because they are on the same side. The other may be arranged at any angle other than these.

As described above, a pair of northern and southern hemispheres are separately provided on both the front and back sides and the left and right sides, and a single needle type and a 24-needle type are provided on both the front and back sides and the left and right sides, and a drive source is provided only on one side and Since the other drive source can be omitted by sharing gears, timing belts and chains, a 24-hour clock can be realized at low cost, and it can also be used for children's educational materials and international business fields. Can also contribute to the activation of

1.1 'Single needle (person)
2.2 'Dial S Sun display 3 Center (Earth)
4 Disc with an indication equivalent to 24 hands (Earth-enlarged version)
