CN2193557Y - Map clock with two kinds of time systems - Google Patents

Abstract

The utility model discloses a map clock which can visually associate time with geographic positions. The utility model is suitable for being used for mastering the local time in the twelve hour system and the twenty-four hour system of all places in the world, and is composed of hands, a transparent clock dial similar to a plane map, a bicolor plane and a rotating shaft. When needing to know the time of a big city in the world, a user can know the local time in the twelve hour system from the hour hand on the clock dial; a scale value displayed on the corresponding bicolor plane below the geographic position of the big city is the universal time in the twenty-four hour system of the big city. If the geographic position of the big city is in an area with a deep color, the big city is at night; an area with a light color represents the day.

Description

Map clock with two kinds of time systems

The utility model belongs to a kind of Chronograph timepiece, two kinds of duration rate systems of particularly a kind of usefulness, and the Chronograph timepiece that can connect the moment value that shows and geographic location.Be suitable for grasping different time all over the world.

Existing Chronograph timepiece is made of pointer, timing clock dial plate, movement assembling.The Chronograph timepiece of selling on the market is exactly this form.When understanding the local time, the pointer of looking at clock and watch promptly know the local time be some, somewhat, several seconds.If know other certain metropolitan times of area in the world, have to spend the calculating time difference and just can know.And same clock and watch can not show with 12 o'clock systems and two kinds of timing of 24 o'clock systems.

Task of the present utility model is that a kind of usefulness 12 hours and 24 hours two kinds of duration rate systems will be provided, and finds out local zone time intuitively, also the Chronograph timepiece of big city, any in the world area zebra time as can be seen.It can connect local time and geographic position.

Task of the present utility model is finished as follows: with earth arctic mid point is the center, after 50 ° of segments to center, the South Pole of south latitude are cast out, it is transparent to be with 50 ° in south latitude that the spherical crown " compression " on the boundary of a piece of land becomes to have, and the plane approximation map of certain intensity is arranged, as dial.Scale on the clock and watch card is the same with clock and watch commonly used to be carved with 12 hours scales that clock.Be equipped with below dial apart from the double-colored plane of garden shape of 0.5 to 5 millimeter of dial, the dial size of double-colored plane and approximate map is consistent, garden Zhou Keyou 0-23 the calibration points corresponding with the equator on double-colored plane.Be divided into punctum 6 from punctum 6 and 18 two double-colored planes of the bundle of lines that is linked to be of punctum and be the light color district to punctum 18 for half garden face of camber line, expression daytime, punctum 18 to punctum 6 is that color region is represented night for half garden face of camber line.The time, minute, second refers to that clock is driven in a clockwise direction by rotation axis and rotates, and double-colored plane makes the speed of double-colored plane to turn around in 24 hours by being contained in forward gear driven rotation axis on the movement, clockwise direction is rotated.

The utility model is easy to use, and available two kinds of duration rate systems are found out local zone time and zebra time intuitively.

Detailed description under doing into below in conjunction with accompanying drawing to the utility model.

Figure one is the utility model structural representation.

(1) is pointer; (2) be dial; (3) be double-colored plane; (4) be rotation axis; (5) be dark district; (6) be the light color district.

With reference to Fig. 1, make local 12 o'clock middle ages of daytime of hour hands indications, and with double-colored plane be 12 o'clock corresponding.When behind the fully-wound, minute, second pointer (1) drives down at rotation axis (4) and rotates by normal clockwise direction, because dial (2) is fixed, so the time of pointer indication is to make the local time in 12 o'clock.Need to understand other parts of the world metropolitan zebra times, see that the scale value on the pairing double-colored plane, this big city (3) is this metropolitan zebra time as long as go up equatorial line from dial (2).Because clock dial (2) is transparent, so can know and find out that double-colored the scale value on (3) clockwise direction below dial (2) equatorial line walks.This metropolitan geographic position is in dark color district (5) the expression night of double-colored (3), then represents daytime in light color district (6).

Claims (4)

1, map clock and watch of forming by pointer (1), movement, dial (2), double-colored plane (3) and rotation axis (4), it is characterized in that pointer (1), map dial (2), double-colored plane (3) according to pointer (1) on dial (2), dial (2) is on the different rotation axiss (4) of the fixed order on double-colored plane (3) in same axle center.

2, according to the map clock and watch of claim 1 regulation, it is characterized in that map dial (2) is is the center with the earth arctic, cast out 50 ° in south latitude to the segment at center, the South Pole, with the transparent almost plane map on the border of 50 ° in south latitude.

3, the map clock and watch of stipulating according to claim 1, it is characterized in that the garden corresponding with the equator of dial (2), double-colored plane (3) be carved with 0 to 23 punctum on week, the bundle of lines that punctum 6 and punctum 18 are linked to be double-colored (3) is divided into the light color district (6) of punctum 18 to punctum 6 dark districts (5) and punctum 6 to punctum 18, two and half garden faces.

4, according to the map clock and watch of claim 1 regulation, it is characterized in that double-colored plane (3) is that rotation axis (4) clockwise on the double-colored plane of forward gear driven (3) on the movement rotates, rotating speed is to turn around in 24 hours.
