Description

[Detailed Description of the Invention] The present invention relates to the wheel train of a timepiece, particularly the rear wheel train, and more specifically, the present invention provides an analog electronic timepiece with a time difference correction function,
This invention relates to a rear wheel train of a multi-functional electronic watch with a dual-time function, etc.

Due to recent technological innovations, digital electronic watches that are easy to operate, such as 12 hour ← → 24 hour switching function, dual time function, and time difference correction function, have become popular. However, in the case of analog electronic watches, 12-hour, 24-hour, time difference adjustment functions, etc. are simply added as single functions, and as demand is low, production volumes are also low, and therefore prices are high. There are many. Furthermore, the dual time function of digital electronic watches such as those mentioned above has the disadvantage that although it is possible to know the time in a specified country, it is very inconvenient to know the time difference between Japan and Japan. .

The present invention was made to eliminate the above-mentioned drawbacks, and it is possible to add a 12-hour system and a 24-hour system to analog electronic watches.
The purpose of this product is to provide a multifunctional watch that can simultaneously display a time system, a dual time function, a time difference adjustment function, and multiple functions at the same time. The gist of the present invention is to arrange the secondary hand at a position further away from the main hand so that the hour hand or the secondary hand can be corrected independently.Therefore, the rotation of the correction wheel that can be engaged with the winding stem is transmitted to the gear train group. A second date wheel, which is rotatable as the winding stem at 1b rotates, is disposed in the middle of the gear train group leading from the correction intermediate wheel to the secondary needle, and
The Hi-no-ura car has a second day's Urakana and a second car that slips under a load of more than a predetermined torque for the second day's Urakana.
It has a day reverse gear, and the second day reverse pinion is engaged with the time difference wheel or the sub-hand wheel.

FIG. 3 is a plan view schematically showing the gear train group of the type [], and since the reference numerals are the same as in FIG. 2, a description thereof will be omitted.

Next, the operation will be explained.

From Fig. 1, in Fig. 3, the reduction ratio from the fourth wheel 7 to the center wheel 8 is set to 1/60, and the minute kana 8a and the hinoura car 1
1. The time difference wheel 9 rotates once every 12 hours by setting the reduction ratio to 1/12 to the cylinder transfer wheel 12, the second date wheel 13, and the time difference wheel 9.

Matabun kana 8a, Hinoura car 11, Tsutsu broker car 12,
The reduction ratio leading to the secondary needle intermediary car 21 and the secondary needle car 10 is set to 1/
By setting the number to 24, the secondary needle wheel 10 rotates once every 24 hours. The second hand 4 is on the fourth wheel 7, the minute hand 3 is on the center wheel 8,
The hour hand 2 is attached to the time difference wheel 9, the sub-hand 5 is attached to the sub-hand wheel 10, and the dial 6 has a 12-hour scale at the position corresponding to the hour hand and a 24-hour scale at the position corresponding to the sub-hand 5. Attach a scale. By moving the winding stem 19 to the second pull position 1c, the winding stem 19 and correction wheel 20 are brought into engagement from the first pull position 1b, where the winding stem 19 and the correction wheel 20 are integrated, as will be described later. The connection is released, the dial engages with the gear train, and the minute hand 3,
The secondary hand 5 is adjusted at the specified time by normal operation.

Next, when setting the hour hand 2 independently at a specified time, when the watch 1 is returned to the first pull position 1b, the crest 19a of the winding stem 19 is pushed into the hole in the correction wheel 20, and the correction wheel 20 is moved to the winding stem. 19, the rotation of the reuse 1 is given to the correction intermediary car 17, but since the second day's Ura car 13 has a slip function 13c, the rotation of the correction intermediary car 17 is the same as the second day's Ura kana 1.
3b and not to the second day rear gear 13a. The rotation applied to the second day's back kana 13b is applied to the time difference wheel 9, so that the hour hand 2 can be independently corrected by forward or reverse rotation of the watch 1. When the watch 1 is returned to the normal position 1a, the peak 19a of the winding stem 19 comes out of the hole in the correction wheel 20, and the integration between the winding stem 19 and the correction wheel 20 is released. However, the winding stem 19 spins idly.

Next, other embodiments of the present invention are shown in FIGS. 4 to 6.

FIG. 4 is a sectional view of a main part of an analog electronic timepiece that can be implemented by partially changing the combination arrangement of the wheel train of the wheel train structure type shown in FIG. 2.

23 is the hour wheel, Hino-ura-guruma 11 and 2nd day-ura-guruma 13
The secondary needle wheel 10 is engaged with the secondary needle wheel 13 on the second day.
It meshes with the Similarly to FIG. 2, a slip function 13c is provided between the second date reverse gear 13a and the second date reverse pinion 13b of the second date reverse wheel 13. This gear train structure is called type []. FIG. 5 is a plan view schematically showing the gear train group of the internal mechanism of the gear train structure type [].

In Fig. 5, 1, 17, 19, and 20 are the same as the gear train structure type [], 1 is a reuse, 17 is a correction intermediate car, 19 is a winding stem, 20 is a correction car, and 1
0, 13, and 23 are as explained in FIG.

Next, the operation of another embodiment will be explained. In Fig. 4, by setting the reduction ratio to the minute pinion 8a, the hour wheel 11, and the hour wheel 23 to 1/12, the hour wheel 23 rotates once every 12 hours, and the hour wheel 23 is fixed to the hour wheel 23. 23a, by reducing the reduction ratio to the second day reverse wheel 13 and the auxiliary needle wheel 10 to 1/2, the auxiliary needle wheel 10 rotates once every 24 hours. Then, attach the second hand to the fourth wheel 7, the minute hand to the center wheel 8, the hour hand to the hour wheel 23, and the auxiliary hand to the auxiliary wheel 10, and attach the 12 hour hand to the hour hand corresponding part of the dial as shown in Figure 6. The scale of the system is placed on the corresponding part of the sub-needle.
Attach a time scale and set the minute and hour hands at the designated time using the normal operation at the second pull position 1c of the watch 1. Next, when setting the secondary hand 5 independently at the specified time, the hour hand of the gear train structure type [] is set independently until the forward and reverse rotation of the watch 1 is applied to the second day counter wheel 13. As in the case of performing the above, by returning the crown 1 to the first pull position 1b, the forward and reverse rotations of the crown 1 are applied to the second day reverse wheel 13. The rotation of the second day reverse wheel 13 is given to the auxiliary needle wheel 10;
Since the is equipped with a slip function 13c, the second
The rotation of the hour wheel 13 is not applied to the hour wheel 23.

Therefore, the sub-hand 5 can be adjusted independently at a designated time. Then, each hand setting is completed by returning the watch 1 to the normal position 1a, which is the normal carrying state in which the winding stem is idling.As shown in Fig. This is an analog electronic watch with an independent time correction function, and by setting the dual time to the specified time with the sub hand 5, you can know the dual time time and the time difference at a glance.

Another way to use this type [ ] is to pull out the watch 1 to the first position 1b, set the secondary hand 5 to the 0 o'clock time, and return the watch 1 to the normal position 1a, so that the secondary hand 5 will start rotating, so the time will change. It can also be used as a simple timer because it can measure the progress of the process.

The cylinder pinion 23a fixed to the hour wheel 23 in the gear train structure type shown in Fig. 4, the second day wheel 13,
The reduction ratio leading to the secondary needle wheel 10 is set to 1/1, and the secondary needle wheel 1
By making the 0 rotate once every 12 hours, the hour hand and dual time become analog electronic watches with a dual time adjustment function that displays 12 hours.When used as a simple timer, it is possible to know the time in more detail. I can do it.

FIG. 7 is a plan view showing still another embodiment of the present invention, in which the scale corresponding to the hour hand is formed in a 24-hour system, and the scale corresponding to the sub-hand is formed in a 12-hour system.

This wheel train structure is basically the same as the type shown in FIG. 2 [ ], so to explain it with reference to FIG.
By setting the reduction ratio leading to the time difference wheel 9 to 1/24, the time difference wheel 9 rotates once every 24 hours. By setting the reduction ratio to the needle wheel 10 to 1/12, the auxiliary needle wheel 10 rotates once every 12 hours. A second hand is attached to the fourth wheel 7, a minute hand is attached to the center wheel 8, an hour hand is attached to the time difference wheel 9, and an auxiliary hand is attached to the sub-hand wheel 10.A 24-hour scale is attached to the part of the dial corresponding to the hour hand, and a sub-hand is attached. By attaching a 12-hour scale to the corresponding part, the hour hand can be adjusted as shown in Figure 7.
It is an analog electronic watch with a 24-hour system and a 12-hour dual time system, as well as a dual time function and a function to adjust the hour hand independently.

As described above, according to the present invention, even an analog electronic watch can have a dual time function, a time difference display function, and
Even in electronic watches with multi-functions such as 24-hour system←→12-hour system display function, the second day wheel with a slip function is placed in a separate position from the hour hand axis and sub-hand axis, In addition, the hour hand or the second hour hand can be corrected by rotating the adjustment wheel that engages at the first pull position of the winding stem, which not only makes it possible to obtain a thin watch, but also allows buttons and winders to be used as external operating members. The multi-functional watch described above can be obtained by simply making some improvements to a conventional watch that allows the winding stem to be positioned in three stages, without requiring a complicated structure such as adding a stem. Therefore, such a multi-function watch can be manufactured with a simple structure and at a low price due to its simple structure.Furthermore, various functions can be combined with one basic structure by combining parts or by replacing several parts. By making various changes, we were able to greatly enhance the product appeal of analog electronic watches.
