(5) embodiment:

The present invention by casing, movement, dial plate, (being printed on the dial of 1-12), second hand, branch is examined and hour indicator (1) is formed.The take up an official post hour hands of the clock and watch that can show in a kind of pointer 12 hours of the world are taken off from the hour hand axle that hour hands are installed, keep minute hand and second hand, hour indicator (1) is contained on the clock and watch hour hand axle that takes off hour hands, just can realize the present invention.Alleged analog timepiece is meant two pins (hour hands and minute hand) or three pins (hour hands, minute hand and second hand) formula clock and watch among the present invention.The present invention is a kind of invention that substitutes hour hands with hour indicator after all.

There is a hole that cooperates with the hour hand axle of clock and watch at the center of the hour indicator among the present invention (1), draws or stamp the figure (2) of hour hands and with 12 circular windows (3) of well-known city, city and 12 arrows (4) that point to different times on hour indicator.The shape of 12 windows can be circular, also can be square or other shapes.It is uniform that 12 windows and 12 arrows are radiation (30 degree).Each window and corresponding arrow are drawn in hour hands on the hour indicator and adjacent arrow and also are 30 degree and distribute on a ray.Hour hands can be drawn in any position of pointing to 1-12 hour numeral in the accompanying drawing, should point to the on-site local time of clock and watch user usually.Circular window on the hour indicator divides upper and lower two parts, represents east, the Western Hemisphere respectively, and the first half is at least one city or regional title in the same time zone, the Eastern hemisphere (or the Western Hemisphere); The title in the latter half at least one city or area in the same time zone, the Western Hemisphere (or Eastern hemisphere), the twenty-four theory district regulation execution that puts in order and formulate by international longitude meeting in each time zone, time zone, two of thing hemisphere places, city sum is 12 on each window.Example: the London in New Zealand's capital Wellington of eastern No.12 District and zero zone is placed on the upper and lower part of the same window, and the time zone sum is 12+0=12, and arrow (4) points at 12 o'clock; The Georgetown, capital, Guyana in Beijing in Dong Ba district and Xisi district is placed on the upper and lower part of the same window, and the time zone sum is 8+4=12, and arrow (4) points at 8 o'clock.East, the city time difference on the Western Hemisphere are 12 on the same window, as the Wellington time be the midnight, the London time then is high noon; Beijing time is at 8 o'clock in afternoon, and the Georgetown time then is at 8 o'clock in the morning.

More than be the pattern and the text layout situation of monoblock type hour indicator of the present invention.City title (literal) on the monoblock type hour indicator window, only horizontal when the accompanying drawing position, As time goes on, hour indicator can rotate along with the hour hand axle of clock and watch, literal on the window can occur tilting or phenomena of inversion, makes troubles for the reading of literal and the grasp of time.In order to address this problem, invented the combined type hour indicator especially.

The combined type hour indicator is made up of disk body (1), 12 time zone discs (3) and 12 little axles (5).Disk body is made by transparent material (as glass, organic glass etc.), with the method for blocking or inlaying disk body is divided into transparent region and zone of opacity.The zone of beating profile line in the accompanying drawing is a zone of opacity.There is a hole that cooperates with the hour hand axle of clock and watch at the center of disk body, has 12 to be the uniform circular transparent window of radiation on the circumference of disk body, window and time zone disc (3) in projection heavy and.On the time zone disc of circular (other shapes also can) eccentric orfice that cooperates with little (5) is arranged, eccentric throw is E.Little axle is contained in the center of the circular transparent window of disk body, and time zone disc (3) is contained on the little axle (5).Time zone disc divides upper and lower two parts, represent east, the Western Hemisphere of the earth respectively, the first half of time zone disc is write at least one city or regional title in the same time zone, the Eastern hemisphere (or the Western Hemisphere), and the latter half is write at least one city or regional title in the same time zone, the Western Hemisphere (or Eastern hemisphere).On the disk body (1) of combined type hour indicator, draw the figure (2) of hour hands and 12 corresponding with circular transparent window be the uniform arrow of radiation (4), each window and corresponding arrow one by on the ray at disk body center, be drawn in one of hour hands on the disk body and 12 arrows on a ray.The time zone sum at place, two cities in east, the Western Hemisphere is 12 on each time zone disc, sees through transparent region (not beating the zone of profile line) and window on the disk body with, can clearly see the city title (literal) on the digital and time zone disc of hour on the dial plate.When clock and watch were run, the disk body that is contained on the clock and watch hour hand axle just rotated synchronously with hour hand axle, and the center of gravity of time zone disc (owing to the reason of off-centre) is in the below of little axle (5) all the time, and the city title (literal) on the time zone disc is in horizontality all the time.The hour hands, arrow and the position of window that are drawn on the combined type hour indicator are in full accord with the monoblock type hour indicator in projection.

The disk body of combined type hour indicator (1) also can be made with opaque material, and 12 circular windows can obtain (Fig. 4) with the method for removing material (hollowing out).At this time need add a back up pad (6) at the back side of disk body, back up pad is connected with disk body, loads onto little axle (5) on back up pad, and time zone disc is contained on the little axle.

Circular transparent window on the disk body among the present invention (1), can be located at the outer shroud (Fig. 1) of the hour numeral of dial plate, also can be located at the interior ring (Fig. 2) of hour numeral, can also all establish window at the inner and outer ring of hour numeral, the window of inner and outer ring is represented different hemisphere respectively.Literal on the time zone disc both can be a Chinese, also can be English or other literal, can also be the array configuration that each window is taked different literals.At patterns such as the national flag of painting various countries on the time zone disc or city city emblems, can realize the present invention equally.

The hour hands of the clock and watch that showed in any pointer 12 hours are in the world taken off from the hour hand axle that hour hands are installed, keep minute hand and second hand, load onto combined type hour indicator of the present invention or monoblock type hour indicator on the hour hand axle of the clock and watch that take off hour hands, common clock and watch just become world clock.
