Description

  The present invention operates without tilting when the hour hand rotates, and the national flag of each country that is geometrically written on the dial makes it easy for the user to see the area and time even when viewed from a distance. It is related to the world clock that can be read.

  In general, there are various types of clocks that constantly operate, such as mechanical clocks, electric clocks, water clocks, and hourglasses, as clocks that inform the user of the time.

  However, these clocks only show the time of one country or region, and cannot simultaneously display the time of a plurality of regions (countries) having different time differences from the standard time.

  In order to solve these problems, there are proposals of Korean Patent KR20-0338270, other Korean Patents KR20-0143300, and KR20-0008672 filed by the present applicant in the technical field of the world clock.

  The above-mentioned world clock has a dial and hour / minute / second hands indicating the time in the center. The dial shows the name of each region (country) for each hour difference from the standard time. Yes. Furthermore, a plate on which 12 numbers indicating the names of each region (country) and the time from 1 o'clock to 12 o'clock are attached to the outer peripheral surface so as to rotate in the same direction as the hour hand.

  This world clock is structured as follows. That is, with the passage of time, the plate with the name of the region indicating the country rotates, and the minute hand and the second hand operate as a common clock. In this way, the user can know the current time of the area by looking at the area name and the number of the time that points to the area name, and also looking at the minute hand and second hand.

As in this Korean patent KR20-0338270 and KR20-0143300, the minute hand and the second hand are the same as in a normal timepiece, but the disc-shaped plate of a world clock in which the hour hand is combined into one. Is heavy and difficult to manufacture due to its integrated shape.
In this way, when the watch inserted on the hour hand rotating shaft with the hour hand plate rotating is hung on the wall, the watch loses its levelness and the practicality brought about by the weight balance without deflection is brought about. There is a risk that the accuracy of the time, which can be regarded as the life of the watch, is lost.
Korean Patent KR20-0008672 is a clock that continuously displays the time on the dial. There is a world map in the center of the dial, and the hour hand, the minute hand, and the second hand indicate the current time. In particular, this indicates the day and night of the earth and the moon, but there is a problem that the time in many regions cannot be clearly recognized at a glance when the distance is long.

The purpose of the world timepiece of the present invention is to correct the tilt deflection of the hour hand plate and the fluctuations on the front and back sides that occur when it rotates, which are the problems found in conventional inventions made using existing technology. It is to prevent it from occurring.
Furthermore, another object of the present invention is to make it easy to recognize the time of each region at the same standard time.
