CN2295235Y - World-time wrist watch - Google Patents

Abstract

The utility model discloses a world-time wrist watch, relating to a wrist watch used for simultaneously indicating the time of every time zone in the world, composed of a watch sleeve, a dial disc, pointers, a machine core and a world time zone ring which are arranged in the watch sleeve. The circumference of the dial is marked with 12-hour system scales and 24-hour system scales, which are used for indicating the local time and the world time. The world time zone ring is inlaid on the watch sleeve at the outer circumference of the dial disc and can be manually rotated along the dial disc. Moreover, the circumference is marked with practical time zone marks and representative city names according to the time difference relationships of every practical time zone. A user only needs to align the mark of a local time zone on the word time zone ring to the corresponding world time on the dial disc at any time in any place, and then the time of every time zone can be simultaneously indicated.

Description

Universal watch

The utility model relates to a kind of wrist-watch or pocket-watch that is used for indicating simultaneously each time zone time of the world.

As everyone knows, also in rotation, the cycle of revolution was 1 year when the earth revolved around the sun, and the cycle of rotation promptly is one day.Like this, variation has throughout the year been arranged not only on the earth, and had round the clock alternately and the difference of time order and function.For the ease of worldwide timing, on the geography earth surface is divided into 24 geographical time zones by longitude since cycle of earth rotation be 24 hours, so the time difference in adjacent geographical time zone is 1 hour.

In the social life of reality, countries in the world and area are not all to be as standard time of this country or this area during with geography, also be to delimit out separately practical time zone during based on geography and according to the actual conditions in various countries and area, stipulate out the standard time separately.For example, though the domain of China across 4 geographical time zones, the whole nation unified with Beijing time as the standard time, so the whole of China has only a practical time zone.Japan is the standard time with the Tokyo time, but it differed 1 hour with Beijing time, rather than 2 hours time differences of geography.The U.S. and Australian domain be also across a plurality of geographical time zones, and they are to be the standard time during with geography basically.India and Iran are the standard time with New Delhi, capital and Teheran time respectively, but the time difference in they and adjacent geographical time zone be not 1 hour, but half an hour or 30 minutes.Obviously, practical time zone and in people's social life, have prior practical significance when practical than geographical time zone with when geographical.Particularly, in aviation, navigation, tourism and other international association, not only to accurately grasp the local time, need to grasp simultaneously the utility time of other countries and regions in the world toward contact.Wrist-watch of the prior art and pocket-watch mostly are 12 hours standards greatly, not only can't distinguish daytime and night, and can only indicate the local time, can not indicate the correct time in other time zone simultaneously, therefore can not adapt to the needs of aviation, navigation, tourism and other international association.

The purpose of this utility model promptly is to design a kind of not only can indicate the locality time but also can indicate generation to shield the universal watch of other area when practical simultaneously.

To achieve these goals, the utility model is used to indicate 24 hours standard scales of universal time at the peripheral mark of existing 12 hours standard Watch dail plate scales, table in the dial plate periphery puts and inlays the annular world time zone ring that cooperates with the table cover simultaneously, world time zone's ring is worked in coordination with 24 hours standard dial scales and also can manually be rotated along dial plate, and the time difference relation by each practical time zone on its circumference indicates each practical time zone mark and represents the city title.When needing other time zone time of the indication world, manual world time zone's ring makes corresponding universal time on 24 hours standard dial plates of local time zone markers align, can encircle and 24 hours standard dial plates be indicated other time zone time of the world simultaneously by world time zone.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model universal watch.

Accompanying drawing 1 is the structural representation of the utility model universal watch.

With reference to the accompanying drawings 1, the utility model universal watch mainly is made of table cover and the dial plate, indicator, movement and the world time zone's ring that are installed in the table cover.Dial plate 1 is circular, is fixed on the central authorities of table cover, and its periphery indicates 24 hours standard scales that are used to indicate 12 hours standard scales of local time and are used to indicate universal time.Indicator comprises hour hands 3, minute hand 4 and second hand 5, be installed in dial plate 1 the center and can be respectively by the time needle tubing, minute hand pipe and second hand pipe drive clockwise direction by movement and rotate, rotation period was respectively 12 hours, 60 minutes and 60 seconds.World time zone's ring 6 is an annular, the table that is embedded in the dial plate periphery puts and works in coordination with the table cover, 6 and 24 hours standard dial scales of world time zone's ring are worked in coordination and also can manually be rotated along dial plate 1, and the time difference relation by each practical time zone on its circumference indicates each practical time zone mark and represents the city title.

In the utility model, the effect of 12 hours standard dial plates and indicator is identical with common 12 hours standard wrist-watches, still is used to indicate the local time; Calibration method during with the school mechanism also identical with common 12 hours standard wrist-watches.When needing other time zone time of indication, manual world time zone's ring makes corresponding universal time on 24 hours standard dial plates of local time zone markers align, can encircle and 24 hours standard dial plates be indicated other time zone time simultaneously by world time zone.

The utility model is simple in structure, and is easy to use, except that being particularly suitable for being made into the patterns such as wrist-watch, pocket-watch, also can be made into patterns such as desk clock, wall clock or case clock.

Claims (1)

1, a kind of universal watch that is used for indicating simultaneously each time zone time of the world is made of dial plate, indicator and the movement of showing cover and be installed in the table cover; Dial plate is circular, is fixed on the central authorities of dial plate, and its periphery indicates 12 hours standard scales that are used to indicate the local time; Indicator comprises hour hands, minute hand and second hand, be installed in dial plate the center and can by movement respectively by the time needle tubing, minute hand pipe and second hand pipe drive clockwise direction and rotate, rotation period was respectively 12 hours, 60 minutes and 60 seconds; Feature of the present utility model is to indicate 24 hours standard scales that are used to indicate universal time in the periphery of 12 hours standard scales of described dial plate; Table in described dial plate periphery puts and is inlaid with and shows to overlap the annular world time zone ring of working in coordination, world time zone encircles and 24 hours standard scales of dial plate are worked in coordination also can manually rotate along dial plate, and the time difference by each practical time zone on its circumference concerns that indicating each practical time zone mark represents the city title with each practical time zone.
