Description

A world watch {A world watch}

The present invention relates to a world clock that enables local time and time of each country to be identified on a single clock. In particular, it is applicable to each country together with the local time by a dial and a pair of hour hands. It's about a world clock that lets you see time at the same time.

As it is well known, the increase of industrial activities and the development of transportation due to industrial development have caused many countries to travel to many countries around the world.

Accordingly, a number of world clocks have been known that allow local time and other city time such as the United Kingdom to be known by a single clock based on the current time.

For example, if you want to know what time the local time is in the trade or consultation, and the current time in the trading partner country, namely, Washington in the United States, or London in the United Kingdom, you can calculate the local time and the difference by looking at the world time difference table. There is a method of checking the time, but this has the concern that the error occurs due to the calculation by the calculation method along with the complexity of the world timetable, which causes a serious problem in commerce.

In this way, the world clock has been devised to make it easy to know the time of the world.

The world clock divides the dial into 24 equal parts to form each time division column, and the division column describes the country or city corresponding to the division, and the number of 1-24 hours is divided into 1-60 equal parts into the compartment. By printing to the outside, the hour hand, minute hand, and the like are configured as known.

For example, one circle is divided into 24 hours on the clock face, and the name of the country of origin is indicated at that location. That is, when Korea (KOREA) is described at 24 hours, it is arranged in the order of Taiwan (TAIWAN), Indonesia (INDONESIA) ... Australia ... (AUSTRALIA) in the right direction. In addition, a division display scale divided by 60 at a position adjacent to the central axis of the clock is shown, and a transparent disc and a minute hand in which numbers are displayed on the outer circumferential surface of the Arabic numeral 1-24 are mounted on the central drive shaft.

As a result, the time point of each country corresponds to a point where the numbers described in the transparent original plate and the names of the countries described in the clock face 1 correspond to the time of each country, and the point where the minute hand is located indicates the minute of each country.

Accordingly, a scale indicating the names and minutes of each country is displayed on the inside and outside of the clock face, respectively, so that the shape of the watch is different from that of a general clock, and it is not easy to check the time of each country.

Accordingly, in the Republic of Korea Utility Model Registration No. 194563, in order to improve the above-mentioned disadvantages, the clock hour hand constitutes one or more hour hands on a transparent disk made of a transparent material, and the names or countries of the world are displayed on the transparent disk at the end of the hour hand. As described by time zone, as the transparent disc is rotated, the time at which the region name or country name of the transparent disc approaches the time display or number on the front of the clock is configured to be the time of the corresponding region or country.

These world clocks are composed of a large number of hour hands, so that the character part of the clock is a very complicated configuration, the time can not be seen easily, there are many reading errors in confused notation, and accurate time alignment is not achieved. It is causing problems such as discontinuity and difficulty of production.

The present invention has been devised to improve the problems of the conventional world clock. In particular, the accuracy of time and the ease of production due to the simple configuration make it possible to easily see the local time and the time of each country in a single watch. It is for the purpose.

In the usual clock that is connected to the movement by the movement (9) by combining the hour hand (10), minute hand (11) and the second hand with a hole in the center of the clock with a time stamp on the dial,

Comprising the marking compartment (21) of each region divided into 24 equal parts on the disc to indicate the country, region and the rotating test plate (20) with the reference hour (22) to each partition line,

On the dial 30 fixed to the outer clock body of the rotary hour hand 20, 24 hours of daytime 1-12 o'clock day and 1 o'clock o'clock at night are described, and again outside the world time 31 Separate local time (32),

In the shaft hole of the rotary hour hand plate 20, as shown in FIG. 3, the hour hand 10 and the minute hand 11 and the second hand which are interlocked with the movement 9 are coupled to each indicator hand,

The interlocking gear 12 and the hour hand 10 are configured by forming a spur gear 13 on the interlocking shaft 12 together with the interlocking shaft 12 by forming the interlocking shaft 12 outside the hour hand 10. The 1/2 gear 16 interlocked by the drive gear 15 is configured to interlock with the rotating hour hand plate 20 1/2 rotation with respect to the hour hand.

The present invention can be applied to a kind of clock, such as for wall hangings, tabletops, wristwatches, or can be produced for 12 hours or 24 hours, the hour hand is shown the hour hand is divided into 12 hours or 24 hours Of course, the reduction may be arranged so that the hour hand is aligned at the location corresponding to the country or place name.

Hereinafter will be described in detail the effect of the present invention configured as described above

1 is a plan view of an important part of the present invention, Figure 2 is a plan view of the operating state showing a state moved 2 hours in the local time of Figure 1 and Figure 3 is a cross-sectional view of the operating state showing an embodiment state of the present invention As shown therein, the dial 30 is fixed to a normal watch body as shown in FIG. For example, in Korea, the time zone in which Korean time is given is indicated.

In addition, the marking plate 21 of each region divided into 24 equal parts is composed on the original plate, and the city name of the corresponding country or region is marked, and the rotating test plate 20 is formed using the reference line 22 as the reference line. 3 is configured in the movement (9),

Through the hour hand 10, the minute hand 11, and the second hand interlocked with the shaft hole of the rotating hour hand plate 20 by interlocking the respective indicator hands and interlocking the interlocking shaft 12 outside the hour hand. The fixed shaft 21 and the reference hour hand 22 and the rotating hour hand plate 20 which describe the station or the name are fixed, and the power of the hour hand shaft is applied to the interlocked shaft 12. When delivered to 2/1, when the local time is moved by one hour, the rotating hour hand plate 20 is moved by 2/1 rotation.

Accordingly, the movement 9 is a driving device of a clock as known in the art by interlocking the second and minute hands 11 and the hour hand 10 according to its operation.

That is, the second hand and the minute hand 11 interlock with the operation of the movement 9 and the hour hand 10 interlocks with it.

The interlocking operation of the hour hand shaft and the interlocking gear 14 and the interlocking shaft 12 on the same axis by interlocking the drive gear 15 fixed to the hour hand shaft as shown in FIG. By interlocking the spur gear 13 fixed to the) will be rotated by the rotary hour hand plate 20 fixed to the interlocking shaft 12 by 2/1 with respect to the hour hand.

At this time, the minute hand 11 and the second hand are moved in units of minutes and seconds regardless of the universal time.

As an example in FIG. 1, when the local time (32) of Korea is at 0:30, Sydney and Guam indicate 1:30 and 1:30 UTC, which is one hour ahead of Korean time. In contrast, Bangkok is pointing to ⑨ at night two hours later than Korean time, so it is confirmed at 22 pm.

2 hours later is shown in FIG.

That is, when the hour hand (10) angle is 2 hours at 0 ° in Korea's local time (32) at 0:30, the hour hand axis moves to 60 ° clockwise as shown in FIG. The hour hand 10 will point to two o'clock.

In addition, the rotating hour hand plate 20 that is rotated 2/1 on the hour hand shaft is moved 30 ° by 2/1 rotation of the 60 ° rotation of the hour hand shaft. It will indicate the matching time of the hour.

At this time, the Guam checks the local time moved to 3 o'clock in the world and 31 o'clock in Bangkok.

As described above, the present invention rotates the rotating hour hand plate 20 indicating a universal time on a single clock to 2/1 from the movement angle of the local time so as to indicate the world time and the current time in the local time and each region of the world. The present invention provides a very convenient world clock by allowing time to be easily distinguished by a single clock, and is also a useful design that can greatly increase the convenience by being portable by applying the present invention to a wall hanging, a tabletop, and a wristwatch. to be.

Universal time is the average time of the Greenwich Meridian with a longitude of 0 °, and each local time and standard time is determined based on this. The standard time of each country is the common time used in one country or region. It is the average solar time of the province, and the country adopts its own standard time.

For example, in Korea, the average local time of 135 ° east is currently adopted as a standard time, so a difference of 30 minutes can be added.

The reason for this is that every time the hardness of a province differs from its neighbors by 15 °, it uses a different standard time for one hour. In other words, when the longitude is shifted east by 15 °, the standard time is 1 hour earlier, and when it is moved west, the hour is delayed 1 hour. The pictorial representation of these steps is the world's standard time zone. The standard time zone must be considered for the date-change line or it may have a system called daylight saving time, also known as summer time.

For example, Kabul, Bombay, Kalkata, Darwin, etc., 30 minutes faster than the standard time using the time zone 30 of the present invention is shown that 30 minutes early at the time indicated by (+30) is indicated do.

In addition, Melboron and Sydney used one hour early in their local time zones, so they marked one hour earlier in their local time.

That is, Sydney should be marked in the Guam time zone in the marking space 21 located one hour earlier than Seoul in Korea, but as described above, one hour is quickly used to write in the marking space 21 of Seoul time. By matching the notation, the time zone is adjusted according to local characteristics such as summer time.

As described above, the present invention is a useful design that can clearly identify local time together with the accuracy of world time since it is marked up to the characteristics of the region.

As described above, the present invention shows 12 hours of local time and 24 hours of universal time on a single clock, and when the local time rotates by 1 hour 30 °, the rotating hour plate, which is the universal time, rotates by 1 hour 15 ° It is a simple design that indicates world time. It is easy to manufacture, has precise accuracy, and can be applied to small or large sized watches with simple configuration. .
