CN2186924Y - Semi-spherical world time clock - Google Patents

Abstract

The utility model relates to a semi-spherical clock with universal time. A clock shaft with one circle of 12 hours of the existing pointer type clock is additionally provided with a multiple pointer disc which is arranged on an hour hand shaft of the common clock and synchronously runs with an hour hand, wherein, the disc is marked with national flags and cities of countries, and combines the zero time zone of Britain and the middle time zone of New Zealand on the pointer of the same time zone of the disc so that the disc can be used as a time zone disc of the eastern hemisphere or the western hemisphere. The utility model has the advantages of easy fabrication and low cost, is particularly used as a hemisphere universal clock by additionally matching a disc with hemisphere time zones based on the existing clock without changes, and is suitable for clock of various types.

Description

Semi-spherical world time clock

The utility model relates to a kind of universal time hemisphere clock and watch, belong to the clock and watch class in the physical apparatus specialty.

Analog timepiece of the prior art, all can only embody at that time from large-scale wall clock commonly used to personal wrist-watch, during local single standard, the time that can't directly show each time zone, the world, when knowing the time in a certain time zone, needs often need to adopt Calculation Method to calculate, and very inconvenient.Though there are a lot of universal clocks directly perceived to come out in the recent period, all must be the clock movement in 24 hours one weeks, could realize the effect directly perceived of universal time.

The purpose of this utility model is to overcome deficiency of the prior art, designs a kind ofly need not change a social system the universal time-piece that watch and clock movement just can intuitively show major country in the hemisphere time zone (city) standard time at that time.

Hemisphere clock and watch when the utility model provides a kind of pointer-type world, its principal character is to utilize existing analog timepiece, do not change under the situation of structure at its hour circle, hour hands, minute hand, second hand and clock and watch casing, casing, set up a pin disk for a long time, the pin disk is arranged on the hour hand axle and hour hands run-in synchronism for a long time, and the pin disc surfaces has the title and the national flag of the Eastern hemisphere or the Western Hemisphere major country (city) for a long time.The following time zone of the time zone of hemisphere (be circumference 1/2nd, 180 °) or hemisphere all is reflected on the whole disk (whole circumference, 360 °) like this.

When the utility model can intuitively show the Eastern hemisphere or the Western Hemisphere major country (city) standard and when local at interior universal time-piece, only need on the basis of existing clock and watch, to add and join many pointers disk that indicates national flag, just can make clock and watch commonly used at present be designed to universal time hemisphere clock and watch.

Below with reference to accompanying drawing the utility model is described in detail:

Fig. 1 is universal time hemisphere clock and watch schematic surfaces.

As shown in Figure 1, the hour circle (1), hour hands (2), minute hand (3), second hand (4) and watch and clock movement, the casing of existing analog timepiece can remain unchanged, set up a pin disk (5) for a long time, to for a long time, pin disk (5) is arranged on the last and hour hands run-in synchronism of clock and watch hour hand axle (6), when it can intuitively show the standard of the Eastern hemisphere or the Western Hemisphere major country (city) and when local, promptly the time zone below 180 ° or 180 ° is launched into 360 °, has gone up national national flag and the city title of putting on this time zone by different time zone at disk (5).As 180 ° are deployed on 360 ° of disks (5), this moment, Britain was 0 °, just was incorporated in 180 ° of New Zealand just to have become same warp on the disk (5).When Britain was 12 noon, New Zealand was exactly midnight's 0 point, and when New Zealand was 12 noon, Britain was exactly midnight's 0 point.Mutual deviation 12 hours.

As shown in Figure 1, in the time of intuitively showing seven national standards in the Eastern hemisphere, be respectively Britain, Russia, India, Burma, China, Japan, New Zealand etc., need not convert and intuitively to show during above-mentioned seven national standards, as New Zealand is 12 noon, Japan's point in the mornings 9, Chinese 8 points, Russia's 3:00 AM, Britain midnight 12 points.

The utility model can intuitively show to the hemisphere Greenwich mean time to have the advantage that need not to convert, and makes easily, and low being easy to of cost promoted.

Claims (2)

1, a kind of universal time hemisphere clock and watch, comprise: when the movement of clock and watch, casing and the hour circle (1), hour hands (2), minute hand (3), second hand (4), hour hand axle (6), the utility model is characterised in that and also is provided with pin disk (5) for a long time, it is arranged on the hour hand axle (6) on clock and watch surface, when clock and watch were walked, its hour hands (2) rotated synchronously.

2, this clock and watch according to claim 1, its feature is that also pin disk (5) is that the time zone of the Eastern hemisphere or the Western Hemisphere (180 °) or hemisphere following (below 180 °) all is reflected on the whole disk (5) (360 °) for a long time, and can put on the title and the national flag of the country (city) in this time zone on disk (5).
