[Clock specifications]
FIG. 1a is a plan view showing a wrist watch 100 according to an embodiment of the present invention.
1 is a case that is an exterior of the wristwatch 100, 2 is a rotating dial that is arranged in the case 1 and is rotated by an operation of a crown 10 described later, 3 is a fixed dial that is arranged around the rotary dial 2, 4 is a lower-case plate arranged on the rotary dial 2 and displays a 24-hour counter that circulates as the rotary dial 2 rotates, 5, 6 and 7 are hour, minute and second hands, respectively, and 8 is a 24-hour hand. . Reference numeral 2 a denotes a city indicator fixed to the rotary dial 2.
10 is arranged on the side surface of the trunk 1 at 3 o'clock side, the crown for the user to perform time adjustment, operation according to the present invention, etc., 9 is the register ring, 11 is arranged on the side surface of the 9 o'clock side, A crown (2) for operating the ring 9. The register ring 9 is printed with a city name representing an hourly difference, and is held in the barrel 1 so as to be rotatable by a crown (2) 11 disposed on the side face of the 9 o'clock side.

  Of the cities printed on the register ring 9, in this embodiment, the city located at the 12 o'clock position is the home time city, and the hour hand 5, the minute hand 6, and the second hand 7 indicate the time of this time zone. Furthermore, by rotating the crown (2) 11, the register ring 9 is rotated and the home time city can be switched. In order to make the position of the home time city easy to understand, a mark indicating the home time city may be given to the fixed dial 3 or a windshield described later. The 24-hour hand 8 indicates the time of the city time zone indicated by the city indication unit 2a provided on the rotary dial 2. The position indicating the home time city is an example, and may be provided at a position other than the 12 o'clock position.

  In FIG. 1a, the hour hand 5, the minute hand 6, and the second hand 7 indicate the time in the London time zone, which is the home time city, and the 24-hour hand 8 also indicates the time in the London time zone indicated by the city indicator 2a. On the other hand, in FIG. 1b, the hour hand 5, the minute hand 6 and the second hand 7 indicate the time in the London time zone, which is the home time city, as in FIG. 1a, but the 24-hour hand 8 is the time zone in Dubai indicated by the city indicator 2a. Is shown.

    As can be seen from FIG. 1, the hour hand 5, the minute hand 6, and the second hand 7 may overlap the lowercase letter plate 4 and the 24-hour hand 8. Therefore, in particular, the hour hand 5 and the minute hand 6 may be made of a light-transmitting member, or may have a structure in which members disposed under each pointer can be visually recognized, such as a configuration in which only the outer periphery is left and the remaining portion is removed. More preferred.

  In the wristwatch 100, a windshield (not shown) formed of a transparent material such as glass is attached to the case 1 so as to cover the rotating dial 2. A back cover (not shown) is attached to the body 1 on the opposite side of the windshield. In the present specification, the direction in which the windshield of the wristwatch 100 is disposed (the front side in FIG. 1) is referred to as the upper surface side, and the direction in which the back cover is disposed (the back direction in FIG. 1) is referred to as the lower surface side.

  In the present embodiment, the rotary dial 2 is rotated in time difference units by rotating the crown 10, and accordingly, the lower case letter 4 is also moved to the vicinity of the city name (time zone) indicated by the city instruction section 2a. Further, the time indicated by the 24-hour hand 8 also changes in time difference. Thus, the wristwatch can intuitively recognize the approximate time of each city (time zone).

Further, even when the small letter plate 4 moves, the hour letter indicating 24 o'clock of the small letter plate 4 faces the 12 o'clock direction of the wristwatch 100. This is realized by rotating the lower letter plate 4 in the reverse direction by θ when the rotary dial 2 is rotated by a certain angle θ. This facilitates reading of the time of the small letter plate 4.
A specific configuration for realizing the above specifications will be described in detail below.

[Clock structure]
Next, the display mechanism of the wristwatch 100 according to the embodiment of the present invention will be described with reference to FIGS.

  FIG. 2 is an exploded perspective view showing the display mechanism of the wristwatch 100 according to the embodiment of the present invention, and FIG. 3 is a block diagram showing the display mechanism of the wristwatch 100 according to the embodiment of the present invention.

[Conceptual description of structure]
First, a conceptual description of the structure of this embodiment will be given with reference to the block diagram of FIG. The rotation operation of the winding stem 37 to which the crown 10 is fixed is transmitted via the continuous wheel 38 and the small iron wheel 16. The portion from the small iron wheel 16 branches to a system for driving the dial plates 2 and 4 and a system for driving the 24-hour hand 8.

  In the drive system of the dial plates 2 and 4, the carrier 29 to which the rotary dial plate 2 is fixed is rotated by the rotation operation of the winding stem 37 via the city correction intermediate wheels (1) to (4) 22 to 25. Thereby, the rotary dial 2 rotates and the lowercase letter 4 moves.

  Further, the rotation of the carrier 29 is transmitted to the lowercase plate wheel 32 to which the lowercase plate 4 is fixed via the lowercase plate intermediate wheels (1), (2) 27, 31, and the lowercase plate 4 is in the opposite direction to the rotating dial plate 2. Rotated. As a result, the 24 o'clock direction of the small letter plate 4 coincides with the 12 o'clock direction of the wristwatch 100.

  In the drive system of the 24-hour hand 8, the 24-hour hand 36 to which the 24-hour hand 8 is fixed is moved via the 24-hour corrected intermediate wheels (1) to (5) 17 to 20 and 40 by rotating the winding stem 37. To drive. Thereby, the time difference of the 24-hour hand 8 can be corrected.

  The 24-hour hand 8 is configured to step by the same drive source (not shown motor and train wheel) as the hour hand 5 (cylinder wheel 15), and is transmitted to the 24-hour intermediate wheel 35.

[Description of specific structure]
Next, a specific structure will be described with reference to FIGS. For grasping the operation, refer to the block diagram of FIG. 3 and the above description as appropriate.

Reference numeral 12 denotes a main plate housed in the trunk 1 and supports various mechanisms of the wristwatch 100.
A center wheel 12, a center wheel 14, and an hour wheel 15 are supported at the center of the main plate 12, and a second hand 7, a minute hand 6, and an hour hand 5 are fixed thereto, respectively. Further, a 24-hour correction intermediate wheel (1) 17 and a 24-hour correction intermediate wheel (2) 18 are arranged on the upper surface side of the main plate 12, and are rotatably held between the main plate 12 and the lower support 21, respectively. . Further, a switching lever (not shown) is disposed on the upper surface side of the main plate 12, and a small wheel 16 is disposed on the upper surface side of the switching lever, and is rotatable between the switching lever and the pressing plate 26. Retained.

  Here, when the winding stem 37 to which the crown 10 is fixed is pulled by one stage, the small wheel 16 is moved from the 24-hour corrected intermediate wheel (1) 17 and the city corrected intermediate wheel (1) 22 to the switching lever. When the crown 10 is in the 0-stage or 2-stage position, the small wheel 16 meshes with the 24-hour corrected intermediate wheel (1) 17 and the city corrected intermediate wheel (1) 22 It has a structure that never happens.

  Further, by rotating the 24-hour corrected intermediate wheel (1) 17, the 24-hour wheel 36 to which the 24-hour hand 8 is fixed can be rotated via a plurality of wheel trains shown in FIG. Similarly, by rotating the city correction intermediate wheel (1) 22, the carrier 29 and the small letter wheel 32 can be rotated through the plurality of wheel trains shown in FIG. Is fixed. The fixing method of the rotary dial 2 is an example, and other methods may be used.

    Next, the drive system for the dial plates 2 and 4 will be described with reference to a sectional view.

  FIG. 4 is a cross-sectional view showing a structure for rotating the carrier 29, and FIG. 5 is a cross-sectional view showing a structure for rotating the lowercase wheel 32.

  On the upper surface side of the lower support 21, a city correction intermediate wheel (1) 22, a city correction intermediate wheel (2) 23 and a city correction intermediate wheel (3) 24 are arranged. Each is held rotatably. Further, the city correction intermediate wheel (4) 25, the lower-case plate intermediate wheel (1) 27, and the 24-hour block 101 are rotatably held between the base 21 and the 24-hour block retainer 28, respectively. The dial 3 is arranged on the upper surface side of the 24-hour block presser 28.

  Here, the 24-hour block 101 is configured by using a carrier 29 having a tooth shape on the outer periphery as a base, and sandwiching a plurality of parts, which will be described later, between a lower-case plate wheel retainer 30 and a 24-hour wheel retainer 34. On the upper surface side of the carrier 29, a small letter plate intermediate wheel (2) 31, a small letter plate wheel 32, and a small letter plate jumper 33 are disposed, and are rotatably held between the carrier 29 and the small letter plate wheel presser 30. Further, a 24-hour intermediate wheel 35, a 24-hour wheel 36, and a 24-hour corrected intermediate wheel (5) 40 are arranged on the lower surface side of the carrier 29, and are held rotatably between the carrier 29 and the 24-hour vehicle presser 34. Is done.

Next, the drive system of the 24-hour hand 8 will be described with reference to a sectional view.
6 and 7 are cross-sectional views showing a structure for rotating the 24-hour wheel 36.
A 24-hour correction intermediate wheel (1) 17 and a 24-hour correction intermediate wheel (2) 18 are disposed on the upper surface side of the main plate 12, and are rotatably held between the main plate 12 and the lower support 21, respectively. The 24-hour correction intermediate gears (3) 19a and 19b are respectively arranged on the upper and lower surfaces of the base 21 and are fitted and fixed on the 24-hour correction intermediate axle 19c so that they can rotate with respect to the base 21. Retained. A 24-hour correction intermediate wheel (4) 20 is disposed on the upper surface side of the lower support 21 and is rotatably held between the lower support 21 and the 24-hour block presser 28.

  As described above, by rotating the crown 10 in a one-stage pulling state, the carrier 29 to which the rotating dial plate 2 is fixed and the small letter plate 4 are fixed through the plurality of train wheels shown in FIG. The lowercase wheel 32 and the 24-hour wheel 36 to which the 24-hour hand 8 is fixed are rotated.

[Description of plan view of dial 2, 4 drive system]
Next, a structure for rotating the carrier 29 and the small letter wheel 32 will be described with reference to FIGS. 8a, 9a, and 10a. When the crown 10 is rotated in a one-stage pulling state, the rotation is transmitted to the small wheel 16 via the winding stem 37 and the pinion wheel 38. Here, the small iron wheel 16 meshes with the city correction intermediate wheel (1) 22 and the 24-hour correction intermediate wheel (1) 17. The rotation of the small iron wheel 16 is transmitted by being decelerated by the city correction intermediate vehicle (1) 22, the city correction intermediate vehicle (2) 23, the city correction intermediate vehicle (3) 24, and the city correction intermediate vehicle (4) 25, and the carrier. 29 is rotated. The rotation of the carrier 29 is transmitted to the lowercase plate wheel 32 via the lowercase plate intermediate wheel (1) 27 and the lowercase plate intermediate wheel (2) 31.

  Further, 24 chevron shapes are provided on the outer periphery of the 24-hour wheel train retainer 34 screwed to the carrier 29, and the carrier 29 is rotated 15 degrees as the carrier jumper 39 laterally presses the chevron portion. Is positioned. By positioning the carrier 29 every 15 degrees, the city indicating portion 2a provided on the outer peripheral portion of the rotating dial 2 fixed to the carrier 29 is changed to one of the 24 cities printed on the register ring 9. It is possible to point to.

9a and 10a show the carrier in the clockwise direction from the state of FIG.
It is in the state rotated by a degree. When the carrier 29 rotates clockwise, the chevron 34a portion of the 24-hour wheel train retainer 28 in FIG. 8a moves to the position of the chevron 34a shown in FIG. When it gets over the apex, it moves to the position of the chevron 34a shown in FIG. 10a. By operating in this way, the rotation of the carrier 29 is positioned by 15 degrees.

  In the present invention, in order to make it easy to read the time indicated by the 24-hour hand 8, as shown in FIGS. The watch 100 is oriented in the 12 o'clock direction.

Next, the reduction ratio from the carrier 29 to the small letter wheel 32 will be described. The number of teeth of the carrier 29 is Z ₂₉ , the number of teeth of the gear and the kana of the small letter plate intermediate wheel (1) 27 is Z _27W , Z _27P , and the number of teeth on the outer peripheral side and inner peripheral side of the small letter plate intermediate wheel (2) 31, respectively. _Are Z _31O and Z _31I , respectively, and the number of teeth of the small letter wheel 32 is Z ₃₂ . When the carrier 29 makes one rotation, the rotation speed of the lowercase plate wheel 32 is 0, and the rotation speeds of the lowercase plate intermediate wheel (1) 27 and the lowercase plate intermediate wheel (2) 31 are N ₂₇ and N ₃₁ , respectively.

  Since the train wheel from the carrier 29 to the small letter wheel 32 is composed of an operating gear device, the reduction ratio can be expressed as in equation (1).

[Formula (1)]

Further, the rotation speed N ₃₁ of the small letter plate intermediate wheel (2) 31 when the carrier 29 makes one rotation can be expressed as the following equation (2).

[Formula (2)]

The number of teeth Z ₂₉ , Z _27W , Z of each of the carrier 29, the small letter plate intermediate wheel (1) 27, the small letter plate intermediate wheel (2) 31, and the small letter plate wheel 32 so that the expressions (1) and (2) are satisfied. _27P , Z _31O , Z _31I and Z ₃₂ are determined.

  By setting such a reduction ratio, the 24 o'clock direction of the small letter plate 4 can be directed to the 12 o'clock direction of the wristwatch 100 regardless of the position of the center of the small letter plate wheel 32.

Further, the small letter wheel 32 has a certain play in the rotation direction due to the backlash of the train wheel between the carrier 29 and the small letter wheel 32. In order to prevent rattling of the lowercase plate 4 in the rotational direction, the lowercase plate jumper 33 laterally presses the tooth profile of the lowercase plate wheel 32. In order to make the 24 o'clock direction of the small letter plate 4 point to the 12 o'clock direction of the wristwatch 100 when the carrier 29 is positioned every 15 degrees, the number of teeth Z ₃₂ of the small letter plate wheel 32 is an integral multiple of 24. It is suitable to set to.

  With the above structure, the rotary dial 2 is positioned every 15 degrees while the crown 10 is rotated in a one-stage pulling state while the 24 o'clock direction of the lowercase letter plate 4 faces the 12 o'clock direction of the wristwatch 100. Can be rotated.

[Explanation in Plan View of 24-Hour Hand 8 Drive System]
Next, a structure for rotating the 24-hour wheel 36 will be described with reference to FIGS. 8b, 9b, and 10b. In the movement of the wristwatch 100, a driving source such as a barrel wheel or a rotor (not shown) rotates the hour wheel 17 to which the hour hand 5 is fixed via a plurality of train wheels. Further, the hour wheel 17 rotates the 24-hour wheel 36 via the 24-hour intermediate wheel 35. The 24-hour pinion 36a of the 24-hour wheel 36 is meshed with the 24-hour corrected intermediate wheel (5) 40, and the rotation from the drive source is the 24-hour corrected intermediate wheel (4) 20 and the 24-hour corrected intermediate wheel (3) 19. , 24 hour correction intermediate wheel (2) 18, and 24 hour correction intermediate wheel (1) 17. Here, rotation from a drive source (not shown) is transmitted to the 24-hour corrected intermediate wheel (1) 17 via the 24-hour wheel 36, but during normal hand movement, that is, when the crown 10 is at the 0-stage position. As described above, the small iron wheel 16 does not mesh with the 24-hour corrected intermediate wheel (1) 17 and the city corrected intermediate wheel (1) 22. Therefore, during normal hand movement, rotation from a drive source (not shown) is transmitted from the 24-hour wheel 36 to the city correction intermediate wheel (1) 22 via the small iron wheel 16 and the carrier 29 is not rotated.

  Further, when the crown 10 is rotated in a one-stage pulling state, the rotation is transmitted to the small wheel 16 through the winding stem 37 and the pinion wheel 38. Here, the small iron wheel 16 meshes with the city correction intermediate wheel (1) 22 and the 24-hour correction intermediate wheel (1) 17. The rotation of the small iron wheel 16 is 24 hour correction intermediate wheel (1) 17, 24 hour correction intermediate wheel (2) 18, 24 hour correction intermediate wheel (3) 19, 24 hour correction intermediate wheel (4) 20, 24 hour correction. The vehicle is decelerated and transmitted by the intermediate wheel (5) 40, and rotates the 24-hour wheel 36. Here, the rotation of the 24-hour gear 36b is transmitted to the hour wheel 15, but it has a holding torque to prevent the hour wheel from rotating due to slip torque of the center wheel 14 or holding torque of a rotor (not shown). Yes. Therefore, the 24-hour pinion 36a and the 24-hour gear 36b are press-fitted and fitted in a rotatable manner, so that the time indicated by the hour hand 5, the minute hand 6, and the second hand 7 arranged at the center of the wristwatch 100 is changed for 24 hours. Only the needle 8 is rotatable.

  Here, the 24-hour correction wheel train and the city correction wheel are arranged so that the carrier 29 and the 24-hour correction intermediate wheel (5) 40 rotate at the same rotation speed when the crown 10 is rotated in the one-stage pulling state. If the reduction ratio of the row is determined, when the carrier 29 is rotated once, the kana 36a can be rotated once for 24 hours. Therefore, independent of the hour hand 5, the minute hand 6, and the second hand 7, the 24-hour hand 8 can display a total of 24 time zones per hour.

  With the above structure, as shown in FIG. 1a, the hour hand 5, the minute hand 6, and the second hand 7 indicate the time of the London time zone, which is the home time city, and the 24-hour hand 8 also indicates the time zone of London indicated by the city indicator 2a. When the wristwatch 100 showing the time moves the city indicator 2a to a position indicating an arbitrary city by rotating the crown 10 by one step, the hour hand 5, the minute hand 6, and the second hand 7 are set to the home time city. While indicating the time, the 24-hour hand 8 can indicate the time of the time zone of the city indicated by the city instruction unit 2a.

  In the embodiment of the present invention, when the home time city is switched, the hour hand 5, the minute hand 6, and the second hand 7 are corrected by a known method in which the crown 10 is rotated in a two-stage pulling state. However, the correction method is an example, and other methods may be used.

[Modification]
(1) In the above embodiment, the time difference is set to 1 hour and the angle unit to which the rotating dial 2 is sent is 15 degrees, but the time difference is 1/2 hour (30 minutes) and the angle unit is 7.5 degrees. It is also good. More finely, the time difference may be 1/4 hour (15 minutes) and the angle unit may be 3.75 degrees.

  Which one should be selected may be determined in consideration of the clock specifications and the processing accuracy of the parts.

(2) Although the 24-hour hand is displayed on the lower-case plate 4 for the 24-hour display, the 24-hour hand 8 is used in this embodiment, it may be displayed using a disk or the like.

(3) The type of timepiece may be an electronic timepiece or a mechanical timepiece, and the drive energy source is not particularly limited. Even in the case of an electronic timepiece, a charging system power source provided with a power generation source may be used in addition to the primary battery. If at least one of the rotary dial 2 and the fixed dial 3 is made of a light transmissive member, a solar timepiece can be realized.

(4) The information indicated by the small clock on the upper surface of the small letter plate 4 is not limited to the 24-hour display, and may be a 12-hour display.

(5) In the present embodiment, the small letter plate 4 is arranged on the upper surface of the rotary dial 2, but the present invention is not limited to this. A hole may be formed in the rotary dial 2 and the lower case letter 4 may be disposed in the hole. In that case, the lowercase letter plate 4 can be arranged on the same plane as the rotary dial plate 2, and the thickness can be reduced.

(6) In the present embodiment, the 12 o'clock position of the small letter plate 4 always faces upward, but the present invention is not limited to this. Depending on the design and specifications, any time (such as 1 o'clock) may always be upward.

(7) Although the present embodiment has been described as a world clock that makes use of the feature of the invention that “the direction of the lowercase plate 4 does not change even if the position of the lowercase plate 4 changes”, it is not limited to this. For example, if the lower-case plate 4 is expressed as “N” at the 12 o'clock position, “S” at the 6 o'clock position, and the 24-hour hand 8 is a small magnet hand, the position of the compass can be changed arbitrarily. It is possible to make a watch with a compass, which is expected to be applied to a wide range of functions.

(8) The step of the 24-hour hand 8 (24-hour wheel 36) is the same drive source as that of the hour hand 5 (hour wheel 15), but may be a different drive source. In the case of an electronic timepiece, the position of the hour hand 5, the minute hand 6, the second hand 7 and the carrier 29 displayed by a known method can be determined inside the microcomputer. Regardless of the position of the hour hand 5, the minute hand 6 and the second hand 7, the 24-hour hand 8 can be rotated to an arbitrary position, so that the city name representing the time difference is printed on the fixed dial 3 or a windshield (not shown). be able to. The home city setting may be indicated by the second hand 8 by a certain operation, but is not limited thereto. By doing so, the crown (2) 11 and the register ring 9 are not necessary, and the cost can be reduced.

(9) Although the present embodiment is configured such that the user can move the center position of the 24-hour hand 8 by rotating the crown 10 in a one-stage pulling state, it may be configured such that the user cannot move it. When assembling the movement, the central position of the 24-hour hand 8 can be obtained even if the crown 10 is rotated in a single pulling state by not incorporating at least one of the carrier drive mechanisms (22-25, 27, 31). Can be configured so that it cannot be moved.
In this way, it is possible to provide a plurality of types of timepieces in which the center position of the 24-hour hand 8 is changed with one movement.
