【発明の詳細な説明】
本発明は世界の各時間帯別時刻を具体的に地図
地名等に一致させ表示する世界時計に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a world clock that displays the time in each time zone around the world by specifically matching it with a map place name, etc.
旅行者が違う時間帯に旅行した場合、一般にそ
の旅行者は旅行先の時刻に時計を合せる。 When a traveler travels to a different time zone, the traveler generally sets his or her watch to the time at the destination.
しかし、その旅行先と常住地の時間差がどのぐ
らいであるか知らなければ、旅行先の時刻を知ら
ない限り旅行先の時刻に時計を合せる事は出来な
い。 However, unless you know the time difference between your destination and your place of residence, you will not be able to set your clock to the time at your destination unless you know the time at your destination.
従来よりこの種の時計として分針、秒針を止め

旅行先の時刻に合せるもの、又二本の時針を設け
第一時針は常住地時刻を、第二時針は旅行先時刻
を表示すべく操作出来るものもある。 Conventionally, this type of watch has been used to set the time at the destination by moving only the hour hand hourly without stopping the minute and second hands, and also has two hour hands, the first hour hand setting the time at the place of residence, and the second hour hand setting the time at the place of residence. Some can be operated to display the time at the destination.

行先の時刻をすばやく読みとる事は一般の旅行者
では非常に難しいと言わざるを得ない。 However, in either case, it is not possible to set the time correctly unless you know the time difference between your place of residence and your destination, or the time at your destination. In addition, as a way to know the time difference between the place of habitual residence and the destination of travel, the outer register ring is divided into 24 equal parts per hour and placed on the outer periphery of the dial, and the name of the city of habitual residence is displayed on the hour hand by reuse operation. There is something that makes it possible to read the time at a travel destination by comparing it to the current time. However, in this case, the hour hand moves every moment, and you have to operate the reuse every time you know the time at your destination, which is very cumbersome. Also, the hour hand is in the 12-hour system, and the city name ring display board for each time zone is
It is very difficult to read because it is a 24-hour system, and it takes a lot of practice to get used to the 24-hour system, and I have to say that it is very difficult for the average traveler to quickly read the time at a travel destination. I don't get it.
本発明の目的は上記欠点を解決し、常住地の現

A display plate for displaying a 24-hour time zone is provided for an hour hand displaying a time-based time, and in a gear train for simultaneously adjusting the hour hand and the display plate using one operating member. By varying the tooth ratio and adjusting the amount of correction between the two, the gear train ratio was configured so that the 24-hour place name matched the 12-hour hour hand, and the hour hand and place name always matched during normal hand movement. When making corrections, set the rotation angle ratio between the hour hand and place name to 1:
It is configured to rotate at a speed of 1.5.

常の裏廻り機構になつている。 In FIGS. 1 and 2, the winding stem 13 supported by the main plate 25 engages with the mandarin duck 14, and the stroke position of the winding stem 13 is controlled by the engagement of the pin 14b provided on the mandarin mandrel with the back pusher 26. I have decided. The mandarin duck 14 is provided with a pin 14a, which engages with an irregularly shaped groove 15a provided in the switching lever 15, and adjusts the position of the switching tool 16 depending on the winding stem pull-out position.
It constitutes a switching mechanism that selects B and an intermediate position between A and B. The switching wheel 16, which is a correction wheel, constitutes a gear train with the small iron wheel 20 and the Tsuzumi wheel 19, and the Tsuzumi wheel 19 is fitted with a square hole in the corner of the winding stem 13, so the rotation of the reuse is the switching work. This is a normal back-rotating mechanism that is transmitted to the car 16.

角度比にて駆動される様構成されている。 During normal hand movement, the switching wheel 16 is selected at the intermediate position between A and B, and the hands are operated with the second pinion 7, the rear pinion gear 6, the rear pinion 5, the first cylinder gear 1, the index wheel 2, and the second pinion 7. The hour hand 9 is driven through the double cylindrical gear 3 at the same rotation angle ratio as the first cylindrical gear 1, and the display plate 8 is also driven by the first cylindrical gear 1, the index wheel 2, and the third cylindrical gear as a display plate hour wheel. 4, and is driven at the same rotation angle ratio as the first cylindrical gear 1. Since both the hour hand 9 and the display plate 8 are configured to be driven at the same rotational angle ratio as the first barrel gear 1, when the reuse is pulled down by one step, the switching mechanism described above moves the switching wheel 16 to the position A. Select. At this time, the switching vehicle 16
Intermediate wheel 17 and third barrel gear 4 that engage with barrel gear 3
The intermediate wheel 18 engages with the intermediate wheel 18. In this case the second
Since the reduction ratios of the cylindrical gear 3, intermediate wheel 17, third cylindrical gear 4, and intermediate wheel 18 are different, the hour hand 9 is supported by the second cylindrical gear 3, and the display plate 8 is supported by the third cylindrical gear 4.
The first cylindrical gear 1, which is engaged with the Japanese back pinion 5 by the reuse rotation operation, is configured to be driven at different rotation angle ratios.

In this case, the switching wheel 16 will be engaged with the Japanese back kana 5, and by the rotation operation of the reuse, the first cylinder gear 1 and below, the hour hand 9, and the display plate 8 as in the case of normal hand movement.
are driven with equal rotation angle ratio. In addition, the second pinion gear 6 and the second pinion 7 are driven to rotate in the same way as in the conventional pinion device, but the second pinion 7 has a slip mechanism with the second gear and a fourth brake mechanism to prevent the second hand 11 from rotating. Stopping is the same as a conventional analog three-hand watch.

転角度比で回転する。 Furthermore, the index wheel 2 has 24 triangular teeth 2b.
The third cylindrical gear 4 is index-coupled with the triangular teeth 4a provided on the third cylindrical gear 4 holding the display plate 8 by the pressure of the leaf spring 12.
Also rotates at the same rotation angle as the first cylindrical gear 1.
Therefore, if a world map with the North Pole as the center is drawn on the display board 8, as shown in FIG. (one rotation per hour). In other words, each of the wheel trains 1, 2, 3, and 4 constitutes a driving means that rotates at the same rotation angle to drive the hour hand 9 and the display plate 8 at the same speed during normal hand movement. If a 24-hour scale is displayed on the dial 21 as shown in Figure 4, if Japan is 2:29:50, the point in Hawaii is between 23 and 0, and Japan is 18 and 19.
Since it is between the scales, we know that there is a 5 hour time difference, and we know that the current time in Hawaii is 7:29:50. However, as mentioned above, it is extremely troublesome for ordinary people to quickly read this time difference. Therefore, in the present invention, as shown in FIG. The wheel 16 is moved to a position (arrow A in FIG. 2) where it meshes with intermediate wheels 17 and 18 that mesh with the second and third cylindrical gears 3 and 4, respectively. Then, by operating a reuse (not shown), the intermediate wheel 1 is moved through the wheel train of the winding stem 13, the Tsuzumi wheel 19, the small iron wheel 20, and the switching wheel 16.
7 and 18 will be driven. Now, when a world map centered on the North Pole is displayed on the display board 8 as shown in FIG. :1.5, the hour hand 9 coupled to the second barrel gear 3 and the display plate 8 coupled to the third barrel gear 4 rotate at a rotation angle ratio of 1:1.5.

The second cylinder gear 3 and the intermediate wheel 17 in the time difference correction means constitute an hour hand correction wheel train for correcting the hour hand 9, and the third cylinder gear Gear 4 and intermediate wheel 1
8 constitutes a display board correction wheel train for correcting the display board 8.

針10とは日ノ裏関係により修正され、通常針合
せが出来る事は言うまでもない。 As mentioned above, the second cylindrical gear 3 and the first cylindrical gear 1 are
The index is connected to 12 equal parts to correspond to the 12-hour system, and the first cylindrical gear 1 is connected to the converter through each gear train from the Japanese back pinion 5, the Japanese back gear 6, and the second pinion 7. Since it is connected to the rotor, if the index coupling force is set to be weaker than the rotor driving force of the converter, the hour hand 9 connected to the second cylinder gear 3 will rotate at 30 degrees without stopping the minute hand 10 and second hand 11. Rotate at a time (1 hour). Similarly, the third cylindrical gear 4 and the first cylindrical gear 1 are connected through an index wheel 2 into 24 equal parts to correspond to a 24-hour system, and the index coupling force is made weaker than the rotor driving force of the converter. If you leave it there, it will rotate by 15 degrees. As mentioned above, the gear ratio of the intermediate wheels 17 and 18 and the switching wheel 16 is set to 1:1.5, so 1
The hour hand 9 will rotate 30 degrees and the display plate 8 will rotate 45 degrees. Generalizing this, if there is a difference between a certain time band and the current location by n hours, the hour hand 9 only needs to rotate by (30n) degrees, and the display plate 8 only needs to rotate by 24 degrees.
(15n) ° as the minute of the time difference in the time system and the hour hand 9
The sum of the movement due to the correction (30n)゜, that is,
If the watch is rotated by (45n) degrees, the time on the hour hand 9 and the point on the display board 8 will match. For example, if the hour hand 9 is advanced by 5 hours from Figure 4, the hour hand 9 will advance 150 degrees and the display plate 8 will advance 225 degrees, as shown in Figure 5.
The hour hand 9 indicates 7:30, and the point where the display board 8 and the hour hand 9 overlap is Hawaii 8a in FIG. Normally, when setting the needle, by pulling the winding stem 13 one step further, the switching wheel 16 is switched to the position shown by the arrow B in FIG. In this case, the hour hand 9 and the display plate 8 rotate as one, and the minute hand 10 is corrected depending on the relationship between the two sides of the day, and it goes without saying that the hands can be set normally.

易いという利点がある。 FIGS. 6 and 7 show other embodiments in which the display board 8b is ring-shaped and the dial 21a is placed on the inside, and the display board 8b shows the names of representative cities by time zone as shown in FIG. The map is displayed in the opposite direction from the map centered on the North Pole shown on the display board 8. Due to this configuration, the rotation direction of the clock and the direction of the time difference match, so the display is displayed relative to the 30° angle of the hour hand 9. The plate 8b only needs to be rotated by 15 degrees, and since the hour hand can be rotated in the direction of the city name during correction, it is advantageous in that it is easy to adjust intuitively.
尚前記第4図に於ける表示板8には北極点を中
心とした地図を示したが、南極点を中心とした地
図を表示しても本発明を基本的に成立するもので
ある。 Although a map centered on the North Pole is shown on the display board 8 in FIG. 4, the present invention can basically be realized even if a map centered on the South Pole is displayed.
