Abstract

The utility model relates to a global clock which is a 24-hour clock. The global clock can simultaneously display the local time of each place in the world, and is the development of a pointer type clock. When in use, the global clock is favorable for information circulation and is convenient for travel across time zones.

Description

Global clock

The utility model relates to a kind of clock and watch, a kind ofly can show the Global clock of local time under the sun simultaneously.

Along with the development of international association, need a kind of clock and watch that can show the full time.Known to the applicant, only the relevant clock and watch application of the Decree of Patent Office of China in 1991 has five.They are: CN2071799U Global Access clock and watch, day for announcing 91.2.20.The CN2072238U universal time-piece, day for announcing 1991.2.27.Time zone, the CN2075355U whole world is logical, uses clock and watch, day for announcing 1991.4.17.CN3009077S World clock clock dial, day for announcing 1991.4.17.CN2090544U24 hour system clock and watch, day for announcing 1991.12.11.

The common feature of above patented claim is that 12 hours systems are all adopted in the every application that relates to universal clock, and are asynchronous with earth rotation; Adopt the clock and watch of making in 24 hours then all not relate to the implication of universal clock.In addition, CN3009077S does not list the Southern Hemisphere in, is unclear on meaning yet.

The utility model adopts 24 hours systems, and axle rotated a week (360 °) in per 24 hours at that time.Hour indicator is discoid, is carved with the figure that the southern hemisphere and northern hemisphere figure overlaps and forms on the disk.Mechanisms such as its minute hand, second hand, calendar are identical with general pointer type wristwatch.

The application can show the local time under the sun simultaneously, compares with above five patented claims, and structure is simpler, and it is more clear to show.

The hour indicator outer toroid limit of Global clock, uniform 24 evenly divideds or numeral, wherein sun mark is carved in 12 positions, and moon mark is carved in 0 position.

The hour indicator of Global clock is a disk, and disc centre is the hour indicator mounting hole, and stamp has southern hemisphere and northern hemisphere to overlap the back figure on the hour indicator.Wherein the Southern Hemisphere is front elevation, and the Northern Hemisphere is anti-view.Two hemispheres uses and disuses lines and color showing respectively, and ocean intersection color is constant, the stack of two hemispheres continent intersection color, and hour indicator is marked with boundary line, time zone and international date line.Generally be carved with one in representative big city, each time zone on the hour indicator at least, mark with color dot or diamond.

Adopt the figure figure after the anti-view in the Southern Hemisphere front elevation and the Northern Hemisphere superposes to form hour indicator, purpose is to make the time on the two hemispheres that is in same time zone be able to synchronous demonstration.Rotated the hour indicator in a week in per 24 hours, actual is exactly the image demonstration of earth rotation.

Below in conjunction with the structure of description of drawings Global clock, minute hand, second hand, three summaries of calendar.1,24 evenly divided dishes; 2, hour indicator.

The factory of any production analog timepiece, only need the hour hand axle rotating speed of original analog timepiece is reduced half, 12 hours system dishes are made into 24 small time takings, the needle-like hour hands are made into disk than the stack back figure that is carved with the southern hemisphere and northern hemisphere map on the disk, can realize that the above method of the utility model is same suitable for clock and table.

Claims

1, a kind ofly can show the clock and watch of local time all over the world simultaneously, it is characterized in that:

Global clock adopts 24 hours systems, and its hour indicator is a disk that is carved with southern hemisphere and northern hemisphere stack figure.

2, Global clock according to claim 1 is characterized in that: the time axle of these clock and watch rotated a week in per 24 hours.

3, Global clock according to claim 1 is characterized in that: 24 evenly divideds or 1-24 numerals are distributed on the outer outer toroid of clock and watch hour indicator, and wherein sun mark is carved in 12 positions, and moon mark is carved in 0 position.

4, Global clock according to claim 1, it is characterized in that, the figure of hour indicator is formed by stacking by the front elevation in the Southern Hemisphere and the anti-view in the Northern Hemisphere, two hemispheres is used different lines and color showing respectively, its mid-continental intersection is superposeed by two kinds of colors, and ocean intersection color remains unchanged.
