JP3003992U - World clock with sun hand - Google Patents

Abstract

(57) [Summary] [Objective] The present invention is to provide a world map and date line on the clock body to know the current time and to clarify the position of the sun on the earth in conjunction with the clock. To aim. [Structure] The present invention has a watch body 1 with a world map 2, 12-hour scale 3, 24-hour scale 4, second hand 5, minute hand 6, hour hand 7, sun hand 8, date calendar 9, date change line 10, equator line 1.
In addition to setting 1 and using it as a normal clock, it is useful for setting the schedule of overseas travel by clarifying the position of the sun on the map with the sun needle 8.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a timepiece in which a world map is arranged on a dial of a timepiece and the position of the sun of the day is pointed by a hand.

[0002]

[Prior art]

 In the past, the scale was equally divided into 12 hours, and the minute and hour hands indicate minutes and hours, but the time could be determined, but the position of the sun could not be determined.

[0003]

[Means for solving the problem]

 As the world has become smaller and more people are traveling abroad, there are more and more opportunities to get on the air plane and cross the date line. At such times, if you know where you are and where the sun is at that moment, you will be able to clarify your future actions and plan easily. Furthermore, if the location of the sun in the home country is known, the inconvenience of making a phone call in the middle of the night can be avoided, and the above-mentioned deficiencies will be solved.

[0004]

[Means for Solving the Problems]

 The present invention uses a scale map of a clock as a world map, and a regular 12-hour scale on the outer circumference of the scale and a 24-hour scale indicating the position of the sun on the concentric circle are arranged on the outer periphery of the scale. By driving the second hand, the minute hand, the hour hand of the normal watch from the center of the main unit and the sun hand indicating the position of the sun, and by showing the date change line on the world map, it can be used as a normal watch and at the same time as the sun. You can see that the position changes every moment. This solves the problem by exposing the approximate time (night or day) in other countries.

[0005]

[Work]

 The second hand drives the scale plate on the outer periphery of 60 minutes for one second, and when the second hand makes one rotation (60 seconds), the minute hand drives the scale plate on the outer periphery of 60 minutes by one scale. When the minute hand rotates once (60 minutes), the hour hand drives one scale. When the clock drives one scale (1 hour), the sun needle drives the inner scale plate one scale and points to the position of the sun on the map. When the hour hand makes one revolution, the sun hand moves to the 180 ° position (12:00 on the inner scale), and when the hour hand makes one revolution, the sun hand moves to the 360 ° position (inner periphery). Move to the 24 o'clock on the scale plate.

[0006]

【Example】

 An embodiment will be described below with reference to the accompanying drawings. 1 is a watch body having a normal clock function, 2 is a world map seen from the northern hemisphere, 3 is a scale plate equally divided into 12 hours, and 4 is a scale evenly divided into 24 hours arranged on the equator line of 11 Plate, 5 is a second hand that drives the outer scale plate for 1 / 60th of a minute in 1 second, 6 is a minute hand that drives the outer scale plate for 1 minute by 60, and 7 is a outer scale plate in 1 hour The hour hand to drive the scale by 1 scale, 8 is the sun hand that drives the inner scale plate by 1 scale in 1 hour, 9 is the date calendar that changes for 1 day in 24 hours, 10 is the date change line on the map, and 11 is It is the equator line showing the equator on the world map.

Since one embodiment of the present invention is configured as described above, it goes without saying that the timepiece body 1 can be used as an ordinary timepiece to know the time, and the world map 2 arranged on the scale plate, With the sun needle 8, the current position and time of the sun can be known at the same time.

[0008]

[Effect of device]

 As described above, the world timepiece with sun hands of the present invention can be used not only as a normal timepiece, but also by showing the position of the sun on the earth, when traveling abroad, the position of the sun in the country where one should go. It is possible to know the approximate time by judging, and it is possible to distinguish between am and pm depending on the position of the sun needle.
