CN2293849Y - Universal clock - Google Patents

Abstract

The utility model relates to a universal clock. A dial disc has a 24-hour scale system. An hour pointer shaft also rotates a circle in 24 hours. An hour pointer is a disc. The disc is printed with a southern hemisphere map of the earth and divided into 24 time zones according to longitudes. Moreover, the disc is marked with international date lines and main city names of every time zone, such as Beijing, Tokyo, London, etc. The time of every time zone can be respectively represented. A minute pointer and a second pointer are unchanged. The outer circle of 24-hour scales of the dial disc is still divided by 60 scales for the minute pointer and the second pointer to indicating minute and second values. Two date windows are simultaneously arranged above a 0-o'clock mark of the dial disc. Different dates of locations at both sides of an international date line can be respectively displayed. The utility model can simultaneously display the time of every place in the world on one clock. The utility model is convenient for a user's life.

Description

A kind of world clock

The utility model belongs to the improvement of Chronograph timepiece.

Before the utility model was made, clock was generally and turned around in 12 hours or 24 hours, but they all can only indicate a certain zone time in the world, just all need can not use a clock jointly with the clock indication various places time separately all over the world.Need know the occasion of time all over the world simultaneously, as International airport, harbour, TV station etc., the clock more than just need using several simultaneously, extremely inconvenient.

Task of the present utility model is for overcoming a kind of improved clock that the above-mentioned deficiency of existing in prior technology provides.

The utility model is to improve realization on the basis of existing technology, it comprises clock shell, clock dial, hour hands, minute hand, second hand, and clock dial is 24 small time taking systems, it is characterized in that hour hands are a disk, uniform 24 scales, and indicate each big city title such as Beijing, Tokyo, London by its time zone, place.

Fig. 1 is the utility model front view

Fig. 2 divides local enlarged drawing for clock portion among Fig. 1

Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing:

According to Fig. 1, shown in Figure 2: 1 is clock dial among the figure, clock dial is 24 small time taking systems, uniform 24 scales, and 4 is minute hand, 5 is second hand, 3 is hour hands, and these hour hands are a disk, are divided into 24 time zones by longitude, corresponding with 24 small time taking systems of clock dial 1, and indicate each big city title of the world by its time zone, place, as Beijing, Tokyo, London etc., represent each location time with it.The hour hands disk revolved and turns around in 24 hours, and is synchronous from turning around from West to East with the earth.The hour hands disk is corresponding with clock dial like this, can demonstrate the time point in each time zone, the world simultaneously, as: 0 point is pointed in Beijing, and morning has been pointed to a bit in Tokyo, and London still is points in afternoons 16 yesterday.Minute hand, the second hand of clock and watch are constant., be used for minute hand, second hand and indicate the every minute and second value respectively still by 60 lattice calibration in clock dial 24 small time taking outer rings.

Two date windows 2 can be established in 0 o'clock of clock dial 1 top, can be painted with earth the Southern Hemisphere map and international date line on the hour hands disk 3, show on the hour hands disk international date line both sides same date not all over the world respectively with two date windows.International date line is crossed 0 point, the regional new daystart of modified line back, and the Qi Qu city enlarges gradually; The area of date line front, scope is dwindled gradually, up to finishing near 0 again.0 of clock dial is arranged at the top, and is identical with the map up north and down south, represent earth sun night simultaneously dorsad; Bottom 12 points are represented noon of the forward sun.

The utility model can also be designed to watch style or desk clock formula.

The utility model image, demonstrate the space-time concept(ion) of the earth intuitively, can point out the time all over the world simultaneously, adapted to modern civilization people life requirement efficiently.

Claims (3)

1, a kind ofly can show the world clock of time all over the world simultaneously, comprise clock shell, clock dial (1), hour hands (3), minute hand (4), second hand (5), clock dial (1) is 24 small time taking systems, it is characterized in that hour hands (3) are a disk, uniform 24 scales, and indicate each big city title such as Beijing, Tokyo, London by its time zone, place.

2, world clock according to claim 1 is characterized in that 0 o'clock top of said clock dial (1) is provided with two date windows (2), and the hour hands disk is painted with earth the Southern Hemisphere map and international date line on (3).
