Description

World time marker

Technical field

The present invention relates to time set, particularly relate to a kind of world's device of zebra time Anywhere of indicating.

Background technology

Regulation in the world: that warp by former address, Royal Observatory Greenwich, London is decided to be 0 ° of warp,, west each minute do 180 °, according to 20 ° of coils with 160 ° of east longitudes of west longitude the earth is divided into two hemisphere of thing traditionally eastwards.And one week of earth rotation needs 24 hours, promptly per hour by 15 ° of longitudes.For standard unified time, stipulate in the world to be divided into a time zone every 15 ° of longitudes, promptly the whole world is divided into 24 time zones, with 0 ° of warp is central meridian, time zone or be called the zero zone from 7.5 ° in west longitude turns to 7.5 ° of east longitudes, be divided into eastern No.12 District, western No.12 District eastwards westwards successively, it is a time zone that east No.12 District, western No.12 District are respectively striden 7.5 ° of longitudes, each time zone all with local time of local area central meridian as the common time of using of the whole district, 180 ° of warps between thing 12 time zones as international date line.Therefore, exist the time difference between each time zone in the world, and present wrist-watch only has hour hands, minute hand, second hand and index dial usually, the time that can only show some time zones, people just need adjust according to the time difference when crossing over different time zone accordingly, make troubles to the user.

Summary of the invention

At the deficiencies in the prior art, purpose of the present invention just provides a kind of World time marker that can indicate each time zone time of the world simultaneously.

For achieving the above object, a kind of World time marker of the present invention, comprise minute hand, second hand, index dial and actuating unit, one end of minute hand and second hand is arranged on the center of index dial, actuating unit drives minute hand and second hand rotates along index dial, also comprise dial plate and time zone disc, the center of described dial plate and time zone disc overlaps with the center of described index dial; Wherein, described index dial is an every minute and second drypoint scale, and the outside surface of this every minute and second drypoint scale circumferentially is divided into 60 equal portions along it, be used for the representative minute and second; The outside surface of described dial plate circumferentially is divided into 24 sub-districts along it, and each sub-district is represented one hour respectively; The outside surface of described time zone disc circumferentially is divided into 24 sub-districts along it, and each sub-district is represented one of them time zone in 24 time zones, the world respectively; Scale mark overlaps during zero second scale mark of the zero of described every minute and second drypoint scale and dial plate zero, and described actuating unit drives per 24 hours of described dial plate and turns around along its center.

Further, described actuating unit is a machine power.

Further, described actuating unit is an electronics power.

Further, the arrow that all has a sensing dial plate on each sub-district of described time zone disc.

Further, each sub-district of described time zone disc shows with east, 12 time zones, west respectively.

Further, each sub-district of described time zone disc shows with the representative cities in east, 12 time zones, west respectively.

Compared with prior art, World time marker of the present invention can indicate simultaneously the correct date of any place, the world, the time, minute, second, no matter go to another time zone by international date line or by a time zone, all do not need to adjust calendar or hour hands, be specially adapted to aviation, military affairs, diplomacy and international association etc. and relate to the occasion that all parts of the world time changes.

Embodiment

Among Fig. 1-3, World time marker is made up of every minute and second drypoint scale 1, dial plate 2, time zone disc 3 and actuating unit (not shown), every minute and second drypoint scale 1, dial plate 2 and time zone disc 3 are circle, their center of circle overlaps, be provided with minute hand 4 and second hand 5 at circle centre position, second hand 5, minute hand 4 and time zone disc 3 are rotated in a clockwise direction under actuating unit drives.The outside surface of every minute and second drypoint scale 1 circumferentially is divided into 60 equal portions along it, is used to represent 60 minutes or 60 seconds.The outside surface of dial plate 2 circumferentially counterclockwise is divided into 24 sub-districts along it, have one day 24 hours respectively, the outside surface of time zone disc 3 circumferentially is divided into 24 sub-districts along it, represent 24 time zones, the world respectively, scale mark overlaps during zero second scale mark of the zero of every minute and second drypoint scale 1 and dial plate 2 zero.The moving circle of second hand 5 revolutions, minute hand 4 rotates lattice; Minute hand 4 rotates a circle, and dial plate 2 rotates a time zone, and promptly dial plate 2 turned around along its center in per 24 hours.Along clockwise direction, the sub-district of time zone disc 3 is followed successively by Dong12Qu, Dong11Qu ... Dong2Qu, Dong1Qu, zero district, Xi1Qu, Xi2Qu ... Xi11Qu and Xi12Qu, wherein, Dong12Qu and Xi12Qu account for a sub-district altogether.All have the cusp of a sensing dial plate 2 on each sub-district of time zone disc 3, be called pointer P, because Dong12Qu and the west shared pointer P in 12 districts, so have only 24 pointer P altogether.Actuating unit and the present actuating unit that wrist-watch and clock adopted are basic identical, and the telecontrol equipment that just will have the hour hands of clock and watch now makes the telecontrol equipment of dial plate 2 into, and by setting, and guarantee that dial plate 2 at the uniform velocity rotated a circle around the center of circle to get final product in 24 hours.

If time of the Dong12Qu of the earth is decided to be standard time of the earth, it promptly is the up-to-date time in the whole world, and the time of Xi12Qu is exactly the oldest global time like this.When the zero flag point of dial plate 2 reaches a certain time zone pointer P point, then this time zone begins to enter standard day district, its anticlockwise border become immediately standard day the district with the mark day before yesterday district the separatrix, this separatrix also will be moved 15 ° and reach new position westwards, nature can be read the date in this time zone thus, the hour hands P in this time zone also just reads the period sequence number from dial plate 2 simultaneously, just knows also thus what time this time zone is.0 period was zero point, and 1 period is for a bit, and the like, because of the minute, second in each time zone all is identical, so minute hand and second can be shared, minute hand and second hand can shared index dials.So zebra time of the present invention, display can be read the whole world correct time for standard day or mark day before yesterday Anywhere.As long as proofreaied and correct initial value, when and where do not need to do any adjustment later on.

For example the cosmonaut is when flying around the earth, leap 20 multi-turns from West to East around the earth on the same day, if they wonder the time under the sun, can read corresponding day Hour Minute Second just only need on the annulus of time zone, find out the pointer in corresponding time zone, and not need to adjust clock and watch; Equally, do not need in each grand hotel, International airport to have hung the clock and watch of tens indication different time zone times yet.

In addition, each sub-district of time zone disc can also be used the representative cities in east, 12 time zones, west respectively, represent as cities such as Beijing, New York, Tokyo, London, be convenient for people to the time on this ground of more intuitive understanding, actuating unit can also adopt the present electronic watch and the power of quartz watch simultaneously, and World time marker of the present invention is made electronic watch, quartz watch etc.
