DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a calendar clock, and more particularly to a technique for improving the visibility of a calendar display such as a date and a day of the week.

[0002]

2. Description of the Related Art Conventionally, many watches equipped with a calendar display are commercially available. FIG. 7 is an enlarged plan view showing the main body of the wristwatch. A circular dial 11 having a flat circular shape is arranged in the display section of the watch case 10, and the dial 11 is covered with a transparent cover glass 12. A calendar window 11a is formed in the 3 o'clock direction portion of the dial 11, and one number display portion 13a (in the illustrated example, "23") of the date dial 13 arranged on the outer peripheral side from the calendar window 11a. )), And one character display portion 14a (“MON” in the illustrated case) of the day indicator 14 arranged on the inner peripheral side is visually recognized.

[0003]

However, in the above-mentioned conventional wristwatch, there is a problem that the number display portion 13a and the character display portion 14a in the calendar window 11a constituting the calendar display are small, so that it is difficult to recognize the wristwatch. In particular, in the case of elderly people, the calendar display may be of little use because the numbers and characters are difficult to read.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a new timepiece structure which makes it easy to visually recognize a calendar display.

[0005]

Means taken by the present invention to solve the above-mentioned problems are as follows.
A calendar timepiece configured to display a calendar such as a day of the week, provided with a plurality of display wheels provided with a display unit representing a plurality of display contents in a rotating direction, and the calendar window includes a display window of the display unit. A calendar clock in which a part of the display contents is displayed and the display contents of the plurality of display vehicles are combined to form a display concept such as a date and a day of the calendar display.

According to this means, the display concept of the calendar display is constituted by combining the display contents of a plurality of display cars, so that a single display concept such as date, day of the week, etc. It is possible to make the display larger than in the case where it is represented by the display content of the display car, and it is possible to perform a calendar display that is easy for the elderly to see.

[0007] Here, as the display vehicle, a number display array provided with a plurality of display contents corresponding to a single-digit number display of ones digit in a plurality of rings on the display unit; A numeral display array in which a plurality of the display contents corresponding to the single-digit numeral display are arranged in a plurality of rings is arranged so as to be rotatable with a tens wheel provided on the display unit, and the display contents of the first-place wheel are arranged. And the display contents of the tens wheel are configured to be adjacent to each other inside and outside the calendar window, and according to the display contents of the first wheel and the tens wheel shown in the calendar window. It is preferable to display a one-digit or two-digit date.

[0010] According to this means, since the ones digit display portion and the tens digit display portion are configured to be rotatable separately, each digit has a large radial dimension. Since the number display section only needs to represent a single-digit number, there is no need to provide 31 number display sections corresponding to the number of days in the month as in the prior art. Since the number of copies can be reduced, the numeral size in the circumferential direction of each digit can be increased, and the display of the number display unit can be further greatly increased.

In the calendar window, it is preferable that a surface of the display portion of one display wheel and a surface of the display portion of another display wheel are arranged on substantially the same plane. .

[0010] According to this means, by arranging the surfaces of the numeral display array of the first digit and the numeral display array of the tens digit on the same plane, it is possible to enhance the sense of unity of the two-digit numeral display. It is possible to reduce the sense of incongruity with the conventional date display, and to further improve the visibility since there is no step between digits.

In this case, the numeral display array of the tens digit includes "0", "1", "2", and "3" constituted by blanks, numbers, characters, figures, and other patterns. ”, At least“ 0 ”,
It is preferable that a plurality of the display contents corresponding to “1” and “2” are continuously arranged.

In the numeral display array of the tens digit, "0",
Since a plurality of the number display portions corresponding to “1” and “2” are continuously arranged, it is possible to reduce the difference between the feed cycle of the first digit and the feed cycle of the tens digit. Since the speed reduction ratio of the wheel train for driving the tens wheel can be particularly suppressed, the driving mechanism can be simplified and downsized.

In this case, in the number display array of the tens digit, four display contents corresponding to “0” are consecutive and the display contents corresponding to “1” and “2” are provided. It is preferable that one of the display contents corresponding to “3” is formed, and the tens digit is intermittently sent at equal time intervals.

According to this means, since the tens wheel is intermittently sent at equal time intervals, a complicated mechanism of the driving mechanism can be eliminated, and the driving mechanism can be further simplified.

In this case, the number display array of the tens digit has nine consecutive display contents corresponding to "0" and the display contents corresponding to "1" and "2". Is 1
It is preferable that one or two of the display contents corresponding to “3” are formed continuously, and that the tens digit is intermittently sent at equal time intervals.

[0016] According to this means, from the 1st to the 30th or the 31st is automatically sent, and only the number of days at the end of the month is adjusted without any other adjustment work, so that a more practical calendar display can be performed. Can be.

Further, the numeral display array of the tens digit corresponds to "0", "1", "2" and "3" which are constituted by blanks, numbers, characters, figures and other patterns. Preferably, the display contents are formed one by one, and the tens digit is intermittently sent at a time interval ratio of 9: 10: 10: 1 or 9: 10: 10: 2 per rotation. .

According to this means, even if the number display portions corresponding to "0", "1", "2" and "3" are formed one by one in the number display array of the tens digit, one is surely provided. Since the number display of the tens digit can be made to correspond to the number display of the tens digit, the number of the tens digit display part can be minimized, and the size of the date display can be further increased.

In this case, in particular, it is desirable to arrange the number display array of the tens digit on the inside in order to enlarge the date display, and the number display array of the first digit indicates "0" to "9". It is desirable to form a number display section corresponding to each one in order to further reduce the number of number display sections of the ones digit and further increase the overall date display.

In each of the above-mentioned means, it is particularly preferable to arrange a plurality of display wheels coaxially in order to effectively use the display area of the clock and to enlarge the calendar display. The calendar display can be made larger by arranging them coaxially with respect to.

Next, an embodiment according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view showing the appearance of a calendar timepiece according to an embodiment of the present invention.
In the present embodiment, the dial 21 disposed in the display section of the watch case 20 is covered with the cover glass 22, and the dial 21 is located at the 3 o'clock position of the dial 21.
a is formed.

On the back side of the dial 21, a first digit wheel 23 and a tens digit wheel 24 are disposed, and “0” is displayed in a numerical display array formed annularly on the outer periphery of the first digit wheel 23. "To" 9 "are displayed in a state of being arranged in the rotation direction. On the other hand, in the numeral display array formed in an annular shape on the outer periphery of the tens wheel 24, numerals “1” to “3” are displayed in a state of being arranged in the rotation direction. Calendar window 21a
Has a number display 23a in the number display array of the first place wheel 24;
Numerals 24a in the numeral display array of the tens digit 24 are visually recognized adjacent to each other, and as a result, are configured to represent a two-digit number for displaying a minimum of 1 and a maximum of 31 dates. .

As shown in FIG. 2, a timepiece movement is accommodated in the timepiece case 20 below the first wheel 23, and an hour wheel 30 connected to the hour hand is disposed above the center of the movement. Have been. The hour wheel 30 is formed with first gear portions 31 and 32 having a circular shape in plan view.
The first gear portion 31 is rotationally driven by a transmission train in the movement, and makes two rotations a day. The first gear portion 31 is
The first driving wheel rotates once a day. The first driving wheel 33 is connected and fixed to the pawl 34, and the pawl 34 is formed on the inner circumference of the first wheel 23 with an internal gear portion 23 b
To rotate the first digit wheel 23 counterclockwise. The internal gear portion 23b has ten teeth, and is driven by a claw 34 that makes one rotation counterclockwise in one day.
Rotates once every 10 days.

The second gear 32 of the hour wheel 30 meshes with the first intermediate gear 35, and the second intermediate gear 36 fixed coaxially with the first intermediate gear 35 meshes with the second drive wheel 37. Second
The driving wheel 37 is connected and fixed to a pawl 38.
Makes one revolution clockwise every two days. A central gear 25 having 15 teeth is fixed on the back of the central part of the tens wheel 24,
The claw 38 engages with the central gear 25.

FIG. 3 shows a plan view of the first and third tens wheels 23 and 24 of this embodiment.
2 schematically shows the cross-sectional structure of the lower part of the dial 21 of the present embodiment shown in FIG. The first wheel 23 is formed in a substantially ring shape, and has an annular numeral display array 23A on the outer peripheral side thereof. The step 23c is provided at the inner edge of the numerical display array 23A.
Is formed, and the outer periphery of the tens wheel 24 is disposed inside the step 23c. An annular numeral display array 24A is also formed on the outer periphery of the tens wheel 24. Ones place car 23
And the surface of the number display array 24A of the tens wheel 24 are flush with each other so as to be substantially the same height.

In the present embodiment, since the numbers are large and are easily visible even to the elderly, the inside of the display frame 21a is displayed at the same height, so that there is less discomfort compared to the conventional date display. It is easy to see.

In the numeral display array 23A of the first digit wheel 23, a total of ten numeral displays 23a each consisting of numbers from "0" to "9" are arranged at equal angular intervals in the circumferential direction. It is printed on. On the other hand, in the numeral display array 24A of the tens wheel 24, "1" to "3"
A total of 11 numeral displays 24a are printed. The number display array 24A is divided into 15 in the circumferential direction, and five “1”, five “2”, and one “3” are printed and displayed in eleven consecutive areas, and the remaining continuous areas are printed. These four areas are blank areas where nothing is printed. This blank part is the tens place “0”
Is a numerical display corresponding to.

The first place wheel 23 includes, for example,
The number string from “0” to “9” may be displayed by repeatedly arranging the number string twice, and may be driven to rotate once in 20 days.

In this embodiment, when the hour wheel 30 attached to the hour hand rotates at a rate of two revolutions per day, the first wheel 23 is moved once every 10 days by the trains shown in FIGS. 2, 4 and 5. It rotates discontinuously once a day at the rate of the circumference. Further, the tens wheel 24 rotates discontinuously once every two days at a rate of one lap every 30 days. Therefore, at the end of the month, the tens wheel 23 and the tens wheel 24
By adjusting the tens digit 24 on the ninth day of each month, a correct calendar display can be performed.

Here, in order to eliminate the need for the adjustment of the ninth day of each month, for example, the numeral display array 24A of the tens digit 24 is divided into 31 in the circumferential direction and nine blanks are continuously arranged at equal intervals. Line up,
What is necessary is to form a numerical display array in which ten “1” s are continuously arranged, ten “2” s are continuously arranged, and two “3” s are continuously arranged. Then, the number of teeth of the central gear 25 fixed to the tens wheel 24 may be 31 and the pawl 38 may be configured to engage with the central gear once a day. The rotation speed of the pawl 38 can be easily changed by the gear ratio of the wheel train transmitted from the hour wheel 30. In this method, the number display must be slightly reduced by forming 31 number displays on the tens wheel 24, but the adjustment operation can be reduced with a simple mechanism.

It is to be noted that the numeral display array of the tens wheel 24 is divided into 30, and 9 spaces, 10 "1", and 10 "2"
And one “3”, the number of teeth of the central gear 25 is 3
By setting the tooth to be sent once a day as 0, one month can be displayed corresponding to the 30th.
In the above configuration, the numerical display arrays are arranged at equal angular intervals, but as long as the time from appearing in the calendar window to being sent to the next display corresponds to the date at equal time intervals. The arrangement of the numerical display is arbitrary.

A blank is displayed in the number display array of the tens digit 24,
"1", "2", "3" are displayed one by one, and the central gear 2
By attaching four pawls 38 engaging with the gear 5 to the gear 37 at irregular intervals and rotating the gear 37 once a month (30 days or 31 days), adjustment of 9 days is unnecessary. can do. Here, the four claws 38 are blank, "1",
9 corresponding to the periods for displaying “2” and “3” respectively:
They are arranged with an angular spacing of a ratio of 10: 10: 1 or 9: 10: 10: 2 (the latter corresponds to 31 days and is more preferred). According to this method, since the number display of the tens digit arranged on the inner peripheral side can be increased, the date can be formed larger. In this case, the tens wheel 24 may be sent in such a manner that the angular intervals of each numeral display are equal angular intervals and the time interval of the above ratio is set. That is, the display may be updated at predetermined time intervals so that the time displayed in the calendar window is linked to the date.

In the above embodiment, the date display is set to the first
Although an example in which the display is made by the two display vehicles of the third and tenth wheels 24 is shown, the calendar display is not limited to the date, but may be the day of the week, the month, or the year. FIG. 6 is an enlarged explanatory view (a), (b) and (c) showing the appearance of the calendar window when the day of the week is constituted by two display vehicles. (A) and (b) display the English display (abbreviated form) of the day of the week in two parts, and (c) display the Japanese display of the day of the week in two parts.

In the above embodiment, the date and the day of the week are displayed by two display vehicles, respectively. However, the present invention uses a plurality of single concepts such as year, month, date, day of the week, etc. , And one concept may be constituted by the display contents of three or more display vehicles. Further, morning / afternoon, age, zodiac, jujube, zodiac, etc. may be adopted as the calendar display.

Further, in the above embodiment, the plurality of display wheels are arranged coaxially about the pointer mounting portion disposed at the center and rotated, but are not necessarily rotated about the pointer mounting portion. It does not need to be performed, and even if they are not formed coaxially, they only need to be adjacent to each other in the calendar window.

[0036]

As described above, according to the present invention, the display concept of the calendar display is formed by combining the display contents of a plurality of display vehicles.
The display can be made larger than in the case where a single display concept such as a day of the week is represented by the display content of a single display car, and a calendar display that can be easily recognized by the elderly can be performed. In particular, the display size in the radial direction of each display vehicle can be increased, and the display size in the circling direction of the display vehicle can also be increased. Since the size can be increased, the calendar display can be configured to have a shape and size that are easy to see.
