Abstract

The utility model discloses timers used in the whole world which are serial products divided into two classes and six species. A first class is provided with an earth rotary clock; a second class is provided with a sun rotary clock. The two classes clocks can display the zonetime in each time zone and local times in the whole world. The accuracy of the timer is similar to a common clock (only displaying the local time of one place). The timer can visually analogize the earth rotation, can clearly display the divisions of timezones, and can be used as a teaching aid.

Description

Whole world clock

The utility model relates to horology, especially as global timer.

Because what international association was particularly traveled increases, people are to showing that the interest of the clock and watch in the moment grows with each passing day all over the world.To the research in this field, though there are many people to set foot in, fail widespread usage so far, its reason is that these work remain the defective in various degree, are difficult to promote.Though disclosed CN85100204 patented claim in 86 years has certain progress, the scale and the literal of its branch dish, hour indicator are still quite a lot of, and be very not eye-catching, do not adopt map, terrestrial globe directly perceived like that again mutually, moreover desire to ask every minute and second to calculate, and it is very not convenient to use.

Task of the present utility model be to provide a kind of easy to use, directly perceived, eye-catching, certain degree of accuracy is arranged and the technology less complex can show the clock and watch of time all over the world.

The Whole world clock series of products of six kinds of patterns of two classes have been designed for this reason.

The first kind is revolved clock for ground, revolves to the branch Northern Hemisphere clock, revolves to the Southern Hemisphere clock and global the three kinds of patterns of clock of revolving.

Revolving to the Northern Hemisphere clock has three timing pieces except that movement, the firstth, the hour indicator (1) that rotates a circle every day counterclockwise, be painted with on the hour indicator along the earth's axis to Northern Hemisphere perspective view, the arctic is positioned at the garden heart.Be painted with 48 warps, 24 longitudes when distinguishing wherein for each, and other 24 be the longitude of each time zone boundary of drawing with another kind of color.Hour indicator outer rim (Chi Daochu) is carved with vernier graduation.The time disk center (limit) structure that local hour hands are installed is arranged.The secondth, time ring (2).The internal diameter of this ring is slightly larger than the hour indicator external diameter, and sliding fit does not have friction and is as the criterion when relatively rotating with it.Garden week 24 five equilibriums, each branch is that preface marks 0～23 24 numeral with the counter clockwise direction, is further divided into six five equilibriums between adjacent two branches.The 3rd parts are the local hour hands (3) that can be installed in easily on the hour indicator.One expansion place is arranged near the tip of this pin, outer rim Cheng Yuan arc, superimposed with the hour indicator outer rim, last quarter (with the time web identical) vernier graduation, the end of pin has the structure that is installed on the hour indicator.

Hour indicator is installed on the gear shaft of revolution every day one, and time ring is installed on the core frame, places outside the hour indicator immovably.The hour indicator one week simulation every day earth rotates from West to East, during carry on it 24 districts warp be equivalent to 24 pointed week day twenty-four theory, the number when numeral on the Shi Huan provides, scale mark provide very several, and vernier graduation provides mark with the situation that meets of ring high scale.When desiring to ask the somewhere, local hour hands are positioned on the hour indicator, the center line of pin are overlapped with the warp on this ground, pointer and with vernier provide the local time on this ground.

To revolve clock similar with revolving to the Southern Hemisphere clock and the Northern Hemisphere, hour indicator (4 ^-) pattern be along ground axial projection the Southern Hemisphere figure, clockwise direction circles every day.Shi Huan (5) increases progressively for the clockwise direction numeral.The local hour hands in the local hour hands and the Northern Hemisphere together.

Revolve clock globally and be ground, the Northern Hemisphere and revolve the two ends that the hour indicator that clock and ground, the Southern Hemisphere revolves clock is loaded on same rotating shaft respectively, towards on the contrary, the hour indicator that makes Northern Hemisphere clock counterclockwise, the rotation of the hour indicator clockwise direction of the Southern Hemisphere clock.

Second class is a day rotating clock, also has to revolve clock Northern Hemisphere day, revolve clock the Southern Hemisphere day and revolved three kinds on clock in global day.Day rotating clock and ground revolve clock hour indicator, the time ring delineation identical, its difference is that hour indicator fixes, and the time ring rotate.Time ring clockwise direction every day in the Northern Hemisphere rotates a circle.Ring counterclockwise rotates a circle every day during the Southern Hemisphere.Clock the day is revolved in the whole world when then being two in south, north, and ring places the two ends of same rotating shaft respectively, rotates synchronously, and ring is clockwise during the Northern Hemisphere, encircles during the Southern Hemisphere to rotate counterclockwise.Anthropomorphic dummy's visual sense sun band all day twenty-four theories from the rotation of east orientation west.The method of its indication time-division is rotating just the same with ground.

Clock of the present utility model can be read the whole world during each time zone easily with warp, makes local hour hands can read Anywhere local time easily.Its precision to one minute, identical with general (no second hand) clock accuracy, manufacturing process can adopt former clock and watch manufacturing process substantially, has only change seldom.Global clock is demonstrated earth spin on mechanism, can be used as teaching aid again and use.

Description of drawings: Fig. 1 is that the hour indicator of the Northern Hemisphere (revolve or day revolve) clock in time encircles; Fig. 2 is that the hour indicator of the Southern Hemisphere (revolve or day revolve) clock in time encircles; Fig. 3 is local hour hands; Fig. 4 revolves the side view of clock for whole world day; Fig. 5 is the utility model front elevation.

Most preferred embodiment 1 doubles the number of teeth of the hour hand gear of existing seat formula mechanical clock, makes the existing clock doppio lunghezza di tempo of its rotating ratio.South, north two hemispheres hour indicator are contained in the two ends of wheel shaft respectively; Ring is contained in respectively on the core frame and the corresponding position of hour indicator during the north and south two hemispheres.Shi Huan is last to replace " 12 " numeral with red sun figure.Vernier graduation is, the time ring between two words every being divided into six five equilibriums, on the hour indicator during two districts line be divided into five five equilibriums at interval so that hour indicator and the time encircle the high scale line on time, provide the even number branch, and when misalignment, provide odd number of points.Local time drypoint degree and pronunciation and hour indicator are together.The shell of clock is made the two sides cloche, and that adorns respectively on two hour indicators of north and south that local hour hands (the first holding position when dispatching from the factory is 120 ° of east longitudes) have just become a seat formula revolves clock globally.If desired, certainly make hanging or console mode.Also available electroclock of movement or quartz analog clock.
