Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem, wherein a plurality of display variations cannot have been manufactured since the position of a date indicator driving wheel cannot have been moved in a timepiece displaying 24 hours by the date indicator driving wheel among conventional timepieces, having a date indicator and a 24-hour small-hand display and since each gear wheel is large in a timepiece in which a hour wheel drives both a date indicator driving wheel and a 24-hour wheel. <P>SOLUTION: By reducing the size of each wheel by driving both a date indicator driving wheel 20 and a 24-hour wheel 50 by an intermediate 24-hour wheel 30 driven by an hour wheel 10, it is possible to manufacture a plurality of display variations in the timepiece. By fixing and arranging the date indicator driving wheel 20, at a position in which the 24-hour wheel 50 is not arranged in any variation, it is possible to change the date in a stable manner. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a train wheel arrangement inside a timepiece, and more particularly, to a train wheel arrangement that efficiently performs a variety of pointer positions in a timepiece that performs a multi-needle display with a plurality of small hands while performing a calendar display with a date wheel. .

2. Description of the Related Art Conventionally, a structure for displaying a calendar of a clock has a structure in which a display wheel such as a day, a day of the week, and a month age is sent using a date driving wheel that rotates once a day.
This date-turning wheel that rotates once a day is rotated by a main vehicle called an hour wheel, and an hour hand for displaying a time is attached to the central axis of the hour wheel.
The hour wheel is configured to rotate once in 12 hours. However, when the rotation direction of the date indicator driving wheel is matched with the clockwise rotation, the rotation direction of the date indicator is also clockwise.

Accordingly, when the date indicator in this rotational direction is corrected by fast-forwarding the crown, when the date indicator is corrected by the forward rotation of the crown (clockwise rotation), the date indicator is also rotated clockwise.
When rotating a crown with a human hand, it is natural to rotate the crown in the same direction of rotation (clockwise) as when turning and tightening a general screw. It is a common common perception that it is preferable.

However, when the direction of operating the crown by hand is clockwise, the direction of moving the thumb is 12 o'clock, whereas when the date wheel rotates clockwise, in a general clock with a date window The date wheel rotates in the direction opposite to the direction in which the thumb moves, and the crown operation direction does not match the date wheel rotation direction, resulting in a feeling of strangeness.
Therefore, it can be seen that the direction in which the date wheel rotates in the direction of turning the crown is natural as a human sense and there is no sense of incongruity.

  Therefore, in the case of a timepiece in which the date driving wheel rotates in the clockwise direction, as a method for solving this uncomfortable feeling, without providing an intermediate wheel between the date driving wheel and the hour wheel, the rotation direction of the date driving wheel is In general, it is common to obtain a good feeling of operation by turning the date wheel in the counterclockwise direction so that the rotation direction of the date dial matches the direction in which the crown is fed.

JP 56-162076 (Fig. 2) Japanese Utility Model Publication No. 6-65890 (Fig. 3) JP 2000-314778 A (FIG. 1) Japanese Patent Laid-Open No. 2002-243869 (FIG. 1)

By the way, it is often performed to attach a hand indicating 24 hours or a disk or hand indicating a time difference to such a timepiece with a date wheel. Documents of Patent Documents 1 to 4 exist as disclosure of such timepiece technology.
However, the conventional structure has the following problems. The problem will be described below with reference to the drawings.

Patent Documents 1 and 2 disclose a technique for efficiently performing these displays without increasing the number of display cars by using a date driving wheel that is usually used only for turning the date dial as a display car for 24 hours or a time difference. Is disclosed. FIG. 4a shows the train chain connection.
However, in order to display for 24 hours with a small hand, it is necessary to rotate the date wheel in the clockwise direction from the necessity of rotating the date driving wheel in the clockwise direction. Since the date wheel rotates in the opposite direction to the direction in which the crown is turned with the thumb, the sense of operation is sacrificed.

  Also, if you use this structure to change the arrangement of the 24-hour car and try to correspond to another dial design, the 24-hour car also plays the role of a day-turning car. The position of the 24-hour car must be moved from the 3 o'clock position to a well-designed place such as the 2 o'clock position or the 12 o'clock position.

On the other hand, in the drive system of the date wheel, there are a date jumper and a date jumper that regulates the position of the date wheel and a date correction mechanism for the date wheel. In order to send the date wheel stably, these parts need to be properly arranged. However, as described above, if the date driving wheel is also used as a 24-hour vehicle, only the position of the date driving wheel is changed every time the design is changed. There may be a problem that the completion time shifts or the date feeding operation is not performed at all.
On the contrary, if the position of the date jumper or the quick correction mechanism is changed when the date indicator driving wheel is changed for stable date feeding, the change scale becomes large and the cost increases.

  As a method for avoiding this problem, Patent Document 4 (FIG. 1) discloses that the train wheel arrangement from the hour wheel 3 is divided into two systems, and the 24-hour drive from the date indicator driving wheel 7 and the sub-needle intermediate wheel 4. A technique is disclosed in which a sub-hand wheel 5 for displaying is branched to give a degree of freedom in the arrangement of the sub-hand wheel. However, as can be seen from FIG. 1 of Patent Document 4, the method of dividing the train wheel arrangement from the hour wheel into two systems particularly needs to use a wide space in the center.

  Therefore, it is not possible to add another display function, for example, a chronograph function, by utilizing the remaining plane space. FIG. 4B shows the plane arrangement of the train wheel connection and the B column a row of FIG. 2 (hereinafter referred to as FIG. 2Ba in this case).

  When actually changing the arrangement of a car for 24 hours using the technology of Patent Document 4, it is necessary to design a product with a different wheel train arrangement as a separate part from the base. It is also necessary to change the layout of the wheel, date jumper, and quick correction mechanism. And, by changing the design from the base, the number of parts increases for each design, which increases the cost and burden of parts management.

  The present invention is a disadvantage of the prior art, while achieving both a good quick correction operation feeling and a general 24-hour vehicle rotation direction, without changing the arrangement of the date indicator driving wheel, date jumper, and quick correction mechanism. Another object of the present invention is to provide a method that can easily change the arrangement of a 24-hour vehicle with a wide movement range and that can make use of the remaining space for other display functions.

In order to solve the above problems, the arrangement of the hour wheel and date driving wheel of the present invention is fixed.
The hour wheel has a 24-hour intermediate wheel that can be repositioned to mesh with the hour wheel to rotate a 24-hour wheel with a small needle for display once a day. It is characterized by having a date turning intermediate wheel which can mesh with a 24-hour intermediate wheel and rotate the date feeding wheel once a day and which can be changed in arrangement.

By implementing the present invention, the following effects can be obtained.
(1) The hour wheel and the date jumper are branched from the hour wheel via a 24-hour intermediate wheel to a 24-hour date wheel, and the hour wheel, date jumper, and quick-correcting mechanism are fixed, and the date wheel is substantially fixed.
By making it possible to change the position of the 24-hour intermediate wheel, the date-turning intermediate wheel, and the 24-hour vehicle, it is possible to easily and widely change the arrangement of the small hands on the 24-hour display while keeping the date wheel feed stable. it can.
(2) Since the embodiment of branching via the 24-hour intermediate wheel is adopted, the hour wheel and the date driving wheel can be designed to be small.
In addition, since it is not necessary to divide the train wheel from the hour wheel into two systems, the drive system of the date wheel and the 24-hour car can be arranged in a compact manner, and the remaining plane space can be used for other display functions. Can do. FIG. 2Bb shows a planar arrangement according to the present invention, which occupies very little space compared to FIG. 2Ba, which is a conventional wheel train arrangement.
(3) Adding a small needle arrangement of these 24-hour cars and other display functions with the conventional method will result in a new design of the component from the base component, increasing the cost and cost of component management. By utilizing the invention, a plurality of display designs can be implemented by recombination of parts without increasing these burdens.

FIG. 8a is a block diagram showing the wheel train structure of the date wheel / 24-hour train wheel and the chronograph wheel train. In particular, FIG. 8a-1 shows the basic configuration. Hereinafter, the present invention will be described for each embodiment.
[1] First Embodiment Hereinafter, a first embodiment will be described with reference to the drawings.
In the first embodiment, the arrangement of the date wheel and the 24-hour car will be mainly described.
(1.1) Display Form FIG. 1 is a diagram in which variations of a standard display form (hereinafter sometimes referred to as “face”) and the corresponding train wheel arrangement are summarized in a table form.
A plan view of the drive wheel train configuration of 24-hour car and date wheel in row A,
A plan view of a drive train wheel configuration in which a chronograph train wheel is added to a train wheel of A train to B train,
The display form of each variation is shown in column C. Also,
What is shown in row a is a display form called “lower third”,
The small hands are arranged at 3 o'clock, 6 o'clock, 9 o'clock,
What is shown in line b is a display form commonly called "vertical third",
The small hands are arranged at 12 o'clock, 6 o'clock, 9 o'clock,
What is shown in line c is a display form commonly called “Swiss face”
The small hands are arranged at the Y position, and are arranged at 2 o'clock, 6 o'clock and 10 o'clock.
These three display forms are popular as standard display forms and are required to be prepared as variations.
In the row of FIG. 1C, the small hand 301 at the 6 o'clock position is a chronosecond hand indicating chronosecond and is common to the three display modes, and there is no change in position. The small hand 71a at the 9 o'clock position and the small hand 71b at the 10 o'clock position are chronograph minute hands that indicate the chrono minute, and only the Swiss face in FIG. 1Cc has a different position, but the pointer itself is the same.
Since these chronograph minutes and chronoseconds will be described in a second embodiment described later, detailed description thereof will be omitted.

(1.2) Wheel train configuration In the first embodiment, in order to easily realize these three kinds of small needle arrangements by recombination of the train wheel, the date indicator driving wheel 20, the date jumper 60, and the quick correction mechanisms 151 to 154 are fixed. By changing the arrangement of the 24-hour intermediate wheel 30 and the date-turning intermediate wheel 40 while maintaining the stability of the date feeding, the arrangement of the 24-hour wheel 50 is recombined to the 12 o'clock position, the 2 o'clock position, and the 3 o'clock position. Realize that. This method will be described below.

In FIG. 1Aa, 10 is an hour wheel, 20 is a date driving wheel, 60 is a date jumper, and 120 is a date wheel (date plate). .
Reference numeral 30 denotes a 24-hour intermediate wheel which is driven by the hour wheel 10 and rotates once in 24 hours, and meshes with and drives the 24-hour wheel 50 and the date turning intermediate wheel 40. The 24-hour wheel 50 and the date driving intermediate wheel 40 are the same as those of the prior art except that the 24-hour wheel 50 and the 24-hour intermediate wheel 30 are engaged with each other.

  FIG. 2 shows a comparison of the train wheel size according to the conventional example shown in Patent Documents 3 and 4 and the train wheel size according to the train wheel configuration in the present embodiment. In the prior art of FIG. 2a row, since the hour wheel 20 and the 24-hour wheel 50 are directly driven by the hour wheel 10, each gear is large. On the other hand, in the present invention shown in FIG. 2b, the 24-hour intermediate wheel 30 and the date-turning wheel 20 and the 24-hour wheel 50 are driven via the date-turning intermediate wheel 40, so that each gear is made small. Therefore, the drive systems for the date wheel and the 24-hour car can be arranged in a compact manner, and the remaining plane space can be used for other display functions.

(1.3) Base member (base plate, train wheel bridge)
FIG. 6 is a plan view showing hole positions of base members such as a base plate and a train wheel bridge, which are used in the description of the following embodiments in addition to the present embodiment.
In FIG.
50a is a hole drilled in the base plate for inserting the tenon of the 24-hour car 50 in order to realize the lower third of FIG. 1Ca.
50b is a hole drilled in the base plate for inserting the tenon of the 24-hour car 50 in order to realize the vertical third in FIG.
Reference numeral 50c denotes a hole formed in a base plate for inserting a tenon of a 24-hour car 50 in order to realize the Swiss face of FIG. 1Cc.

30a is a hole drilled in the ground plate for inserting the middle wheel 30 for 24 hours in the case of the lower third and vertical third,
Reference numeral 30b denotes a hole formed in the base plate for inserting a tenon of the intermediate car 30 for 24 hours in the case of a Swiss face.
40a is a hole drilled in the base plate for turning the middle wheel 40 in the case of the lower third and vertical third,
40b is a hole drilled in the main plate for turning the intermediate wheel 40 in the case of a Swiss face.
By providing a side hole for the car to correspond to each display variation, it is possible to cope without creating a new base plate or train wheel bridge.
Incidentally, 30a and 30b, 40a and 40b, 50c and 50b are arranged symmetrically with respect to a line L1 connecting the axis of the hour wheel 10 and the axis of the date indicator driving wheel 20, respectively. It facilitates recombination between the eye and the Swiss face.

(1.4) Change from Lower Third to Vertical Third First, a change from the lower third shown in FIG. 1Ca to the vertical third shown in FIG. 1Cb will be described.
The 24-hour wheel 50 at the 3 o'clock position shown in FIG. 1Aa is moved from 50a which is the 3 o'clock position in FIG. 6 to 50b which is the 12 o'clock position in FIG. Thereby, the arrangement of the 24-hour wheel 50 is changed from the 3 o'clock position in FIG. 1Aa to the position 12 in FIG. 1Ab without changing the positions of the hour wheel 10, the date feeding wheel 20, the 24-hour intermediate wheel 30 and the date turning intermediate wheel 40. It can be changed to the hour position.

This is because the position of the 24-hour intermediate wheel 30 is changed to a straight line connecting the 24-hour intermediate wheel 30 and the hour wheel 10 by using the train wheel connection of the present invention. On the other hand, in this example, the train wheel is arranged so that the display position can be easily changed by arranging the devices at diagonal positions.
Specifically, in order to change from the lower third to the vertical third only by rearranging the 24-hour wheel 50, 30a is approximately equal to an axis L2 passing through the winding stem 140 and a straight line L3 orthogonal thereto. It arrange | positions on the straight line L4 which passes along the center of the hour wheel 10 by the angle to divide. The location on L4 is determined by the meshing and size of the gears.
In this way, if a plurality of positions to be displayed are arranged diagonally in advance with respect to a straight line connecting the intermediate car and the hour wheel, it is easy to move the display car without moving the intermediate car. A display vehicle can be arranged.
The position 30b is determined to be a position symmetrical to L1 that is a straight line connecting the hour wheel 10 and the date indicator driving wheel 20 with respect to the position 30a determined as described above.

(1.5) Change from the lower third to the Swiss face Next, the change from the lower third shown in FIG. 1Ca to the Swiss face shown in FIG. 1Cc will be described.
When changing from the lower third to the vertical third shown in (1.4), there was a space for moving the 24-hour car 50 at the 12 o'clock position, so the change was made only by moving the 24-hour car 50. It was possible.
On the other hand, in the case of this change, the date turning intermediate wheel 40 is present at the 2 o'clock position where the 24-hour car 50 is moved, and therefore the date turning intermediate wheel 40 needs to be moved.
Further, in order to maintain the meshing between the 24-hour wheel 50 and the 24-hour intermediate wheel 30, it is necessary to move the 24-hour intermediate wheel 30 inevitably.

Changes are made as follows.
(1) The position of the 24-hour intermediate wheel 30 is moved from 30a to 30b in FIG.
(2) The date turning intermediate wheel 40 is moved from 40a to 40b in FIG.
(3) The 24-hour car 50 is moved from 50a to 50c.
Thereby, the arrangement of the 24-hour car can be changed from the 3 o'clock position in FIG. 1Aa to the 2 o'clock position in FIG. 1Ac without changing the arrangement of the hour wheel 10 and the date indicator driving wheel 20.

In the case of this change, it is necessary to move the intermediate date wheel 40 in order to place the 24-hour vehicle 50 at the position where the intermediate date wheel 40 has existed until then. As shown in FIG. 9, this arrangement is possible by securing the arrangement position of the date turning intermediate wheel 40 in either the left or right area of the straight line connecting the date driving wheel and the hour wheel.
This is made possible by arranging 30a and 30b, 40a and 40b, 50c and 50b symmetrically with respect to a line L1 connecting the axis of the hour wheel 10 and the axis of the date indicator driving wheel 20, respectively.

  In the above-described three display modes, the 24-hour wheel 50, which is substantially the same size as the date indicator 20 for one rotation per day, is arranged at 12:00, 2 o'clock, and 3 o'clock, respectively. Is arranged. As described above, by arranging the date driving wheel at a position where the display wheel is not disposed, it is possible to perform stable date feeding while increasing display variations. The position of the date indicator driving wheel 20 is preferably fixed, but if it is a date indicator on the 31st, even if it is moved at an interval of 11.6 ° which is one day, a major problem in the date feeding operation is No.

As described above, it is possible to move the position of the 24-hour car 50 to 12:00, 2 o'clock, 3 o'clock without changing the arrangement of the date indicator driving wheel 20 while using a common base. There is no need to change the arrangement of the date jumper 60 or the quick correction mechanisms 151 to 154 whose arrangement is determined relative to the date indicator 120. Therefore, stable date feeding is possible even if the display form is changed.
Furthermore, the hour wheel 10 always rotates in the clockwise direction because of the attachment of the hour hand. However, the 24-hour wheel 50 is always in the clockwise direction by interposing the 24-hour intermediate wheel 30 with the 24-hour wheel 50. It can also be rotated.

  Since the date indicator driving wheel 20 is also transmitted from the hour wheel 10 to the 24-hour intermediate wheel 30 and the date indicator driving intermediate wheel 40 to be rotated, the date indicator 120 can be rotated counterclockwise. Even when the crown is rotated manually, the date wheel 120 rotates counterclockwise, so that a good operational feeling can be obtained.

In addition, while supporting the above three display modes, it is possible to pack the 24-hour display and day display drive systems in a compact area of approximately 12 o'clock to 3 o'clock. It becomes possible to plan for multi-functionality.
1, 2, 3, 7, 8 b, and 8 c, the difference between the spur gear and the kana teeth is also expressed in the structure of the date driving wheel and the 24-hour wheel. Even when the kana teeth are changed to kana teeth or the connection of kana teeth is changed to flat teeth, the train wheel structure of the present invention can be established.

[2] Second Embodiment Hereinafter, a second embodiment will be described with reference to the drawings.
In the second embodiment, the chronograph train wheel can be efficiently arranged in the space vacated by the first embodiment, and the arrangement of the chronograph train wheel can be devised to increase the display variation efficiently. It shows what is possible.
Hereinafter, description will be made based on the drawings.

FIG. 8a is a block diagram showing a connection configuration of a 24-hour / day wheel train and a chronograph train.
8b and 8c are variations including the arrangement shown in FIG. 1, and can be realized by using the connection of FIG. 8a showing the configuration of the 24-hour / day wheel train and the chronograph train. It is the figure which showed the train wheel arrangement | positioning of the possible display form. 8d and 8e are a block diagram showing a configuration of a 24-hour / day wheel train and a chronograph train wheel and an external view showing a display form that can be realized by each train train block construction.

(2.1) Basic train wheel configuration As shown in the first row of FIG. 8b and the third row of FIG. 8c, when three small hands are displayed, most of the chronograph train wheels have a 24-hour / day wheel train. It is arranged in an area excluding the area from about 12:00 to 3 o'clock, and in particular, it is arranged in an area on the 9 o'clock side with L3 as a boundary (see FIG. 3).
This is because a 24-hour / day wheel train is arranged in the region from 12:00 to 3:00, and a train wheel 151-154 for early correction such as a date wheel is arranged in the region from 3:00 to 6:00. It is.

The chronograph train wheel according to the present embodiment includes a chronograph motor rotor 200 to a second chronograph intermediate wheel (1) 210, a second chronograph intermediate wheel (2) 220, and a second chronograph intermediate wheel (3) 230. The second chronograph wheel 300 is driven through two intermediate wheels.
Further, from the second chronograph wheel 300, the minute chronograph wheel is passed through three intermediate wheels: a minute chronograph intermediate wheel (1) 310, a minute chronograph intermediate wheel (2) 320, and a minute chronograph intermediate wheel (3) 330. 400 is driven.

The display mode is changed by arranging the positions of the second chronograph wheel 300 and the minute chronograph wheel 400 mainly in four directions of 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock. However, the chronograph train wheel is formed only when the gears from the rotor 200 to the minute chronograph wheel 400 are engaged with each other, for example, as shown in FIG. Therefore, in order to enable the arrangement change of the second chronograph wheel 300 and the minute chronograph wheel 400 in four directions while maintaining the wheel train configuration in FIG. 8a-1, the minute chronograph intermediate wheel (1) 310, Any one of the minute chronograph intermediate wheel (2) 320 and the minute chronograph intermediate wheel (3) is arranged substantially coaxially with the hour wheel 10 and another chronograph around the middle wheel substantially identical with the hour wheel 10 A system train wheel is arranged. In this embodiment, the minute chronograph intermediate wheel (2) 320 is arranged substantially coaxially with the hour wheel 10. FIG. 7 is a perspective view showing a state in which the minute-counting intermediate wheel (2) 320 and the hour wheel 10 are arranged substantially coaxially.
Block diagrams other than those shown in FIG. 8a-1 will be described as appropriate in the description of display change described later.

  Incidentally, in FIGS. 3 and 7, the minute chronograph intermediate wheel (2) 320 is arranged eccentric with respect to the hour wheel 10 in the 8 o'clock direction. This is to ensure that there is a little space in the 12 o'clock-3 o'clock direction where each gear has a relatively large 24-hour / day driving wheel train, and the intermediate teeth of the hour wheel 10 and the minute chronograph The purpose is to prevent interference with the car (1) 310. As a result, it is possible to secure a space in the 12 o'clock to 3 o'clock direction and to efficiently arrange a large size chronograph intermediate car in a space-saving manner. Become.

(2.2) Base member (base plate, train wheel bridge)
The main plate 130 and the train wheel bridge are also provided with a side hole for coping with the change in the arrangement of the chronograph wheel train.
In FIG.
70a is a hole formed in the base plate for inserting a tense of the minute-counting wheel 400 in order to realize the lower third of FIG. 1Ca and the vertical third of FIG. 1Cb.
Reference numeral 70b denotes a hole formed in the main plate for inserting a tense of the minute chronograph wheel 400 in order to realize the Swiss face of FIG. 1Cc.

60a is a hole formed in the main plate for inserting a tense of the minute chronograph intermediate wheel (3) 330 in the case of the lower third in FIG. 1Ca and the third vertical in FIG. 1Cb.
60b is a hole formed in the main plate for inserting the tense of the minute chronograph intermediate wheel (3) 330 in the case of the Swiss face of FIG. 1Cc.
Reference numeral 60c denotes a hole formed in the main plate for inserting the tense of the minute chronograph intermediate wheel (3) 330 in the case of the second vertical in FIG. 8d-A2.
60a can be arranged at left and right positions symmetrical to the straight line L2 that passes through the axis of the hour wheel 10 and the 9 o'clock display position 70a of the minute chronograph wheel, and similarly 60b is the position of the minute chronograph wheel. Even at the 10 o'clock display position 70b, it can be arranged at left and right positions that are symmetrical with respect to a straight line L5 passing through the axis of the hour wheel and 70b.
