Abstract

The invention provides a full time zone clock disc for real-time display of time in different zones, composed of hands and a clock face, where the clock face is an external disc marked with 24-hour full time, there is a hour disc concurrently acting as a hand, and a world map with a pole of the earth as a centre is marked on the hour disc. It adopts a module-24 clock disc, changes a hour hand into a hour disc, which uniformly rotates a circle every 24 hours, clockwise and this direction consistent with the direction where the earth rotates from the west to the east, thus the time in some zone of the world is the marked time the joint line between the zone and the central dot points to, therefore it can reflect the time in each time zone and even in each place and has advantages of full display of time in full time zones, strong visual display and miniaturization.

Description

The full time-zone clock dish

One, technical field

The present invention relates to a kind of dial of full-time system global clock, especially the full time-zone clock dish.

Two, background technology

By prior art, with the time of a dial indication different time zone, perhaps use world time zone's synoptic diagram on big plane, the mode that shows with electronics under each city is put on the time, and is used as the airport; Perhaps the world clock with tower booth formula shows city name and time around in order, and this mode often is the decoration on avenue and square.

Prior art has following shortcoming: (1) is difficult to comprise global all regions; (2) and usually the profile difference of clock and watch is very big; (3) all can not do to such an extent that the fully small and exquisite individual of making wears; (4) can not show dynamically intuitively which area, the world is in daytime, which area is in night.

Three, technology contents

Technical matters: the invention provides a kind of full time-zone clock dish that can comprehensively reflect the district from all parts of the world time, it is strong to have intuitive, the advantage of Miniaturizable.

Technical scheme: the present invention is a kind of full time-zone clock dish that is used for showing simultaneously the different regions time, form by pointer and clock face, clock face is the outer dish that indicates 24 hour full-time time, be provided with the double hour indicator of doing pointer in the dish outside, to have with earth limit be the world map in the center of circle to sign on hour indicator.

Technique effect: 1. the present invention adopts 24 system dial plates, change hour hands into hour indicator, give on it that to have with earth limit be the map at center, especially having identified is the signal area, the world in the center of circle with the Geophysical South Pole, dial plate be just down 0 point, just 12 points, the orientation of also representing the sun, a positive left side is 6 points, the positive right side is 18 points, the boundary that 6 and 18 s' line is equivalent to daytime and night is the approximate location of circle in morning and evening, dial plate indicate global time zone, international date line and interested city, hour indicator is fixed on the hour hand axle with circle centre position, turn round by enclosing at the uniform velocity with per 24 hours one clockwise, and this direction is consistent with earth sense of rotation from West to East, like this, the time in a certain zone is the identified time on the outer dish that line pointed to of this area and centre point in the world, so the present invention can reflect each time zone, whole world time in each place even, has the advantage of the detailed time showing in full-time district; The present invention is daytime near half hour indicator of 12 positions, and opposite half hour indicator in addition then just in time is night, therefore, this indication intuitive is strong, because this structure of the present invention can be made the very little clock of volume, so, the present invention can realize miniaturization, and can be used for carrying.In a word, just can show that with a dial time of whole world all regions, the Dynamic continuous display world is in the part on daytime and is in the part at night, it is strong to have intuitive, the advantage of Miniaturizable.2. the top of outer dish is 12 points, the below is 0 selecting for use, make the area on the hour indicator that enters half zone be in daytime, area on the half region hour indicator then enters night, this Scheme Selection just and people the perception experience of the earth and position of sun relation is matched, therefore, these technical measures have more increased intuitive of the present invention.

Four, description of drawings

Fig. 1 is a structural representation of the present invention.

Five, specific embodiments

The present invention is a kind of full time-zone clock dish that is used for showing simultaneously the different regions time, form by pointer and clock face, clock face is the outer dish 1 that indicates 24 hour full-time time, coil outside and be provided with the double hour indicator 2 of doing pointer in 1, to have with earth limit be the world map of centre point to sign on hour indicator 2, the present invention is externally coiled and the definite of hour indicator mutual alignment relation can have many kinds to select, that is: 12 can be positioned at any on the outer dish and not blocked part by hour indicator, be positioned at its symmetric points zero point, consider the intuitive that clock shows, it is the world map of centre point that present embodiment is marked with the Geophysical South Pole at hour indicator 2, and coiling 1 top point midway outward is 12 points, and the below mid point is zero point, the left mid point is 6 points, right-hand mid point is 18 points, is marked with international date line at hour indicator 2, and the center of circle of hour indicator is located on the hour hand axle, time alignment with arbitrary time zone, aim at such as 0 time zone (universal time also claims GMT (Greenwich mean time)), at this moment other local times must be accurate.Make the at the uniform velocity clockwise direction operation of hour indicator with per 24 hours 1 circles, then the time of all regions all can read in the world, and the part that is in daytime and night in addition also can intuitively be found out.

Claims (3)

1, a kind of full time-zone clock dish that is used for showing simultaneously the different regions time, form by pointer and clock face, it is characterized in that clock face is the outer dish (1) that indicates 24 hour full-time time, be provided with the double hour indicator (2) of doing pointer in the dish (1) outside, having with earth limit in the last sign of hour indicator (2) is the world map in the center of circle.

2, full time-zone clock dish according to claim 1, it is characterized in that being marked with the Geophysical South Pole at hour indicator (2) is the world map centre point, and the top point midway of outer dish (1) is 12 points, and the below mid point is zero point, the left mid point is 6 points, and right-hand mid point is 18 points.

3, full time-zone clock dish according to claim 1 and 2 is characterized in that being marked with international date line at hour indicator (2).
