Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a clock that at first glance can tell the world's day and night at the current time.

[0002]

[Prior art]

 Conventionally, there are clocks that display accurate time in each major city in the world.

[0003]

[Problems to be solved by the device]

 Conventional clocks that display the time of each major city in the world display accurate time, but they have the problem of being difficult to see. The present invention has been made in view of such problems of the conventional technology, and the purpose thereof is to understand the day and night parts of the world at a glance, and to make telephone communication with overseas more and more increasing. Not only is it very convenient for dealing with the time difference that is essential for international exchange such as business trips and business trips, but it is also easy for the infant to understand, and the day and night of the world where the whole family can have fun and have fun. It aims to provide a self-explanatory watch.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the clock for understanding the day and night of the world in the present invention arranges a developed map of the world map centered on the North Pole over the entire plane within the base frame of the clock, and arranges it on the upper side. A disc-shaped day / night disc that has a semi-circular portion transparent and the remaining semi-circular portion semi-transparently colored is provided at the position, and the day / night disc is attached to a rotating shaft that rotates once in 24 hours to discriminate day / night. Rotate the board on the development view of the world map. On the contrary, the day / night disc is fixed over the entire plane in the frame, and the development map of the world map is rotated at the lower position.

[0005]

[Action]

 According to the rotation of the earth, the night part of the world is distinguished from the day and night. The translucent part of the plate 3 covers the top of the development map 1 of the world map, so you can see the day and night of the world at a glance.

[0006]

【Example】

 Examples will be described with reference to the drawings. In FIGS. 1 and 2, a development of a world map centered on the North Pole is shown in FIG. 1 in which a circle is attached over the entire plane of the base frame 2 of the watch. The day / night distinguishing plate 3 is made of a plastic thin plate, for example, a transparent circular thin plate such as polyethylene or vinyl chloride resin, and the semi-circular portion is colored semi-transparently to indicate the night area. A rotary shaft which is rotated once in 24 hours by, for example, a reduction gear by a motor drive unit 5 provided on the lower side of the central portion of the exploded view 1 and whose tip portion is projected to the upper side of the exploded view 1 of the world map. It is attached to the tip position of 6 so as to rotate in the horizontal direction, and the day / night distinguishing plate 3 is provided on the development map 1 of the world map so as to rotate once in 24 hours. The known vital time display 7 is inserted in a development view of a world map, for example.

In addition, in FIG. 3, the day / night discriminating plate 3 whose semicircular portion is colored semitransparently 4 is fixed in the base frame 2 of the watch, and the development map 1 of the world map in the lower position is attached to the rotary shaft 16. It may be rotated once in 24 hours. The day / night distinguishing plate 3 is not necessarily limited to a circular shape, but may be formed in a semi-circular shape having only a semi-transparently colored portion 4. Further, the ordinary timepiece is replaced by the ordinary time display device 7. The needle may rotate.

[0008]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. Day and night around the world centering on the Arctic are obvious even from a distance, and it is convenient to use in offices that have transactions with foreign countries, and at home at home with friends and family even for young children. Since the day and night can be discriminated, it is possible for all the family members to talk about each other and have a friendly relationship, which is useful for learning the time difference.

[Brief description of drawings]

FIG. 1 is a vertical cross-sectional view of a clock that shows the world day and night.

FIG. 2 is a plan view of a timepiece that enables day and night of the world to be known.

FIG. 3 is a vertical cross-sectional view showing another embodiment of a timepiece capable of identifying day and night in the world.
