BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display structure of a timepiece, and more particularly, to a watch having a new display style.

[0002]

2. Description of the Related Art An ordinary timepiece displays the time by indicating an index on a dial with an hour hand and a minute hand. In recent years, a watch having a new display form has been proposed due to diversification of watch designs and applications. It has been commercialized. For example, there has been a display in which the hour hand and the minute hand are both formed of a disk, and the time is displayed by reciprocating the hour hand and the minute hand within a certain angle.

[0003]

In each of the above prior arts, the hour hand and the minute hand each indicate the time by pointing an index on the dial, and the basic part of the display form has not been changed. For this reason, something new and different from the conventional display mode has been desired.

The present invention has been made in view of the above problems, and has as its object to provide a display structure of a timepiece that realizes a new sense of display.

[0005]

According to the present invention, there is provided a timepiece display structure in which an index is provided on a front surface and is attached to an hour wheel to rotate and display an hour digit of a time by a moving position of the index with respect to a specific stationary position. A minute hand, which is attached to the minute hand wheel and rotates, and displays the minute digit of the time by inserting the index of the hour display plate.

In the timepiece display structure, the time display plate is set to rotate counterclockwise, and the minute hand is set to rotate clockwise.

The indicator in the display structure of the timepiece is rotatably attached to the hour display plate.
It is configured to rotate with the rotation of the hour display plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the display structure of a timepiece according to the present invention, an hour indicator of a time is displayed by moving an index to a specific stationary position by rotating a display plate when an index is provided on a front surface. Further, in this display structure, the minute hand is displayed by rotating the minute hand and pointing the index of the hour display plate.

As described above, since the minute hand displays the minute digit by indicating the index on the moving hour display plate, the rotation speed of the minute hand is adjusted to correspond to the rotation of the hour display plate. ing. That is, when the hour display plate rotates counterclockwise and the minute hand rotates clockwise, when the hour display plate rotates once in 12 hours, the minute hand is set to rotate 11 times in 12 hours. By rotating the hour display plate and the minute hand in this way, the minute hand indicates an accurate time by inserting an index according to the rotation of the hour display plate.

[0010]

FIG. 1 is a front view showing a display structure of a timepiece according to an embodiment of the present invention, and FIG. 2 is a sectional view showing a drive unit thereof. In the figure, reference numeral 2 denotes an hour display plate, and "1-1" is displayed on the front surface thereof.
The indices 4 of “2” are sequentially arranged in the clockwise direction. At this time, the display plate 2 has a circular shape in the present embodiment, and the center thereof is attached to the hour wheel 6 so as to rotate counterclockwise.

Reference numeral 8 denotes a minute hand, which is disposed so as to point the indicator 4 in front of the hour display plate 2 and is mounted coaxially with the hour display plate 2 on the minute hand wheel 10 so as to rotate clockwise. I have.

As shown in FIG. 2, the minute hand wheel 10 is rotated by the rotation of the rotor 12 being transmitted through reduction gears 14 and 16. In a general timepiece, the rotation of the minute hand wheel 10 is transmitted to the hour hand wheel via a minute wheel, but in this embodiment, since the hour hand wheel 6 needs to be rotated counterclockwise, the first date wheel is rotated. The rotation is transmitted to the hour wheel 6 via the minute wheel 18 and the second date minute wheel 20 meshing with the minute wheel 18.

Since the hour display plate 2 and the minute hand 8 in this embodiment rotate in opposite directions, it is necessary to reduce the rotation speed of the minute hand 8 by the rotation speed of the index 4 rotating together with the hour display plate 2. . Therefore, by changing the reduction ratio when the minute hand wheel 10 and the hour hand wheel 6 are driven, the hour hand wheel 6 is set to rotate once every 12 hours, and the minute hand wheel 10 is rotated once every 12 hours.
It is set to make one rotation.

The minute hand 8 has an indicator 4 similar to an ordinary watch.
, The hour display panel 2 displays the hour digit of the time based on how much rotation the indicator 4 has moved with respect to the predetermined specific stationary position.
For this reason, in the present embodiment, the mark 22 is provided on the bezel, the case, or the like, and the mark 22 is set as a specific stationary position. The time digit of the time is displayed depending on which index 4 is located at the place.

In the display structure having the above structure, if the hour display plate 2 and the minute hand 8 are in the state shown in FIG. 1, "12:15" is displayed. When one hour has elapsed from this state, as shown in FIG. 3, the hour display plate 2 rotates 30 degrees counterclockwise and the minute hand 8 rotates 330 degrees clockwise. "1" is mark 2
The minute hand 8 is rotated slightly past the point 2, the minute hand 8 is again rotated to the point where the indicator 4 indicates "3", and "1:15" is displayed.

In the above embodiment, the hour display plate 2 is rotated in the counterclockwise direction and the minute hand 8 is rotated in the clockwise direction. ,
The minute hand 8 may be rotated counterclockwise. However, in this case, it is necessary to arrange the indices 4 of “1 to 12” sequentially in the counterclockwise direction. For this reason, the display form becomes more novel, but in terms of readability of the time, turning the minute hand 8 having a higher rotation speed in the clockwise direction makes it easier to read the time.

In the above embodiment, the hour display plate 2
Is rotated once in 12 hours.
It is also possible to change to rotate. In this case, the minute hand 8 is set to rotate 23 times in 24 hours, and as shown in FIG.
The hour digit indices 4a of "2" are sequentially arranged in the clockwise direction, and the minute digit indices 4b such as "0, 15, 30, 45" are sequentially arranged in the clockwise direction. As a result, the hour digit and the minute digit are displayed by the hour digit index 4a indicated by the mark 22 and the minute digit index 4b indicated by the minute hand 8, respectively.

FIG. 5 is a front view showing a display structure of a timepiece according to another embodiment of the present invention. In the present embodiment, the time is displayed by rotating both the hour display plate 2 and the minute hand 8 in the clockwise direction as in a normal timepiece. Accordingly, the hour hand wheel 6 and the minute hand wheel 10 for driving the hour display plate 2 and the minute hand 8 respectively remove the second date wheel 20 in FIG. It is configured to rotate through.

At this time, the indicator 4 of the display panel 2 has an hour digit indicator 4a consisting of numerals "1 to 12" arranged in a counterclockwise direction in the vicinity of the outer periphery thereof, and a clockwise indicator inside the hour digit indicator 4a. And a minute digit index 4b formed of a number such as "0, 15, 30, 45".

When both the hour display plate 2 and the minute hand 8 rotate clockwise as in this embodiment, the minute hand 8 is
It is necessary to rotate faster by the rotation speed of
When the hour display plate 2 rotates once every 12 hours, the minute hand 8 moves to 12
It is set to rotate 13 times per hour.

In the second embodiment, the hour digit index 4a at the mark 22 at the specific stationary position is the hour digit of the time, and the minute digit index 4b pointed by the minute hand 8 is the minute digit of the time.

In this embodiment, it is possible to display the time by rotating both the hour display plate 2 and the minute hand 8 in the counterclockwise direction. In this case, the hour digit indicator 4a and the minute digit indicator 4b are used. Need to be arranged in the opposite direction.

It is also possible to display the time for 24 hours by rotating the hour display plate 2 once every 24 hours. In this case, as shown in FIG. 2
It is necessary to change the minute hand 8 to 25 rotations in 24 hours.

In any of the above-described embodiments, when the hour display plate 2 rotates, the index 4 provided on the front surface of the hour display plate 2 also rotates about the rotation center of the hour display plate 2, and the index 4 is a numeral or the like. In this case, the top and bottom may be reversed by the rotation of the hour display plate 2. For this reason, as shown in FIG. 7, the direction of the index may be set in advance so that the lower part of each numeral or the like faces the center of rotation, but to make it easier to read the time,
It is best to attach the indicator 4 to the hour display plate 2 in a rotatable state. That is, as shown in FIG. 8, the indicator 4 is formed by attaching the indicator plate 4c having a number or the like formed on the front surface to the hour display plate 2 so as to be rotatable about the shaft 4d. The shaft 4d is located above the numbers and the like formed on the index plate 4c, and is set so as to support a position off the center of the index plate 4c. Since the position supported by the shaft 4d is eccentric in this manner, the index plate 4c
Will always rotate so that the lower part of the numbers or the like faces vertically downward. For this reason, when the hour display plate 2 rotates, the index plate 4c rotates around the axis 4d with the rotation, and the direction of the numerals and the like on the front surface is always kept constant. As a result, the top and bottom of the index 4 do not reverse, and the time can be easily read.

[0025]

According to the present invention, an hour display plate which displays the hour digit of time and also serves as a dial,
At this time, by using the minute hand for pointing the indicator on the display plate, it is possible to provide a display structure of a timepiece having a new sense of time display mode.

Further, since the hour display plate also functions as a dial, there is no need to provide an independent dial, and the timepiece can be thinned by reducing the space for providing the dial.

Further, the hour display plate is rotated counterclockwise to
By rotating the minute hand clockwise, the time can be easily read.

Also, by attaching the index to the hour display plate in a rotatable state, the direction of the index can be kept constant even when the hour display plate rotates, and the time can be read more easily.
