Abstract

The utility model relates to a universal clock. The clock only change an hour hand into a world time zone place name plate on the basis of an existing clock. Representative city names in world time zones are arranged into a circle or a spiral circle according to the positions of the time zones on a disc. The time difference between two cities at eastern and western hemispheres in a same angle on an inner ring and an outer ring is twelve hours. The structure of clock is simple, convenient and practicable. The clock can be widely used for organizations, institutions and individuals for controlling local times or times of other time zones in the world.

Description

Universal clock

The utility model belongs to a kind of clock and watch of representing each time zone time of the world simultaneously.

The world in information age today, along with development of productivity and progress of science and technology, with frequent, people not only will know the local time more closely for the contact of human society and international contacts, and increasing people also usually needs to know the time in other time zones, the world.For example, people go abroad because of thing, fly New York by air, by plane from Beijing, not only will know the Beijing time of taking off, and also will understand the New York time that aircraft arrives.And existing clock and watch can't be represented, and are very inconvenient.

The purpose of this utility model is that research is a kind of simple in structure, convenient and practical, with low cost, represents the clock and watch of local time and other time zone times of the world simultaneously.

Technical solution of the present utility model is: a kind of clock and watch of representing each time zone time of the world simultaneously.Under the situation of the volume that does not change existing clock and watch, profile, gearing, according to per 24 hours of the earth from circling (360 °), and existing clock and watch are 12 hours walking (rotation) circles (360 °), one 24 hours weeks of earth rotation are existing clock and watch walking 2 circles, passing through any relative coils of the earth, 12 hours principle of thing hemisphere both sides time phase difference.The utility model is by casing for clock and watch, gearing, world time zone's place name dish connects the major-minor hour hands, minute hand, second hand, dial is formed, its special character is that expression is by circumference or helix and 12 grids that the time zone dividing line is formed on world time zone's place name dish, mark has representational city, each time zone, world title, zone position is arranged in circle or spiral coil on time, time zone (western No.12 District) in time zone of new daystart (eastern No.12 District) and end in old a day is the head of circle or spiral coil, tail, the east of the same angle of Internal and external cycle, two city time phase differences in the Western Hemisphere 12 hours.Clear for ease of expression on less wrist-watch, can select representational important city, the most frequently used time zone, world title to be arranged in a circle, at thickness or the color differentiating of the thing hemisphere city of same circle title, in order to avoid the time entanglement with mesh lines.

Time zone central meridian in the expression local time connects main hour hands, the central meridian in other time zones is with one section scale or pointer vice hour hands, main hour hands are represented the local time, the center scale in other time zones or pointer (secondary hour hands) are represented other time zone times, and some country is not adopted with the time zone is the standard time of unit, city title when not being whole with the difference of " GMT (Greenwich mean time) ", as New Delhi, Teheran, Kabul, Rangoon etc., be shown in the inboard or the outside of city title circle of the whole time difference by the time location tables.Thereby represent each time zone time of the world simultaneously.

The utility model is compared with existing clock and watch, and the advantage that has is that function is more complete, more convenient practicality.Existing clock and watch can only be represented the local time, when these clock and watch can be represented the locality simultaneously with and time in other time zones, the world, made things convenient in international contacts and the activities involving foreign nationals clocking requirement to other time zone times of the world.

The drawing of accompanying drawing is described as follows:

1---world time zone's place name dish (being connected as a single entity) with main hour hands 3

2---dial

3---main hour hands (being connected as a single entity) with world time zone place name dish 1

4---minute hand

5---second hand

6---the center scale (secondary hour hands) on other time zone central meridians

7---the time zone dividing line

8---distinguish the thick frame or the mark in east, city, the Western Hemisphere

World time zone's place name dish 1 and main hour hands 3 are connected as a single entity, this dish is gone up expression world time zone's representational city title, zone position is arranged in spiral coil or 2 circles (Fig. 1, Fig. 2) on time, time zone (western No.12 District) in time zone of new daystart (eastern No.12 District) and end in old a day is the initial and end of circle or spiral coil, middle time zone is connected the east of the same angle of Internal and external cycle, two city time phase differences in the Western Hemisphere 12 hours (as Wellington and London) with the Dong Yi district.Clear for ease of expression on less wrist-watch surface, can select representational important city, the most frequently used in the world time zone to be arranged in 1 circle or spiral coil (Fig. 3), drive world time zone's place name dish 1 and main hour hands 3, minute hand 4, second hand 5 walkings (rotation) by gearing.Main hour hands walking (rotation) week is 12 hours, and minute hand week of walking is one hour, and second hand week of walking is one minute.
