Abstract

PURPOSE:To obtain the timepiece which allows the use of the display itself as an interior decoration by dividing the numbers of the date and the characters of the day of the week to two elements and forming these elements in such a manner that the two elements overlap only in the part of the display windows provided on a dial. CONSTITUTION:The numbers from 1 to 31 are respectively partly indicated as a date display 1a in the positions divided to 31 sections on a date wheel 1. The three English letters indicating the day of the week are respectively partly indicated as a day display 2a in the positions divided to 7 sections on a day wheel 2. The numbers from 1 to 12 for time display are marked at equal intervals in a toric shape at the central part on a dial 3. The dial 3 is provided with a date display window 3a indicating the numbers from 1 to 31 when mated with the date display 1a indicated on the date wheel 1 on the rotating locus of the date wheel 1 and is provided with a day display window 3b indicting the characters to designate the day of the week when mated with the day display 21 indicated on the day wheel 2 on the rotating locus of the day wheel 2. While the display is illegible with the date display 1a and the day display 2a alone, the numbers of the date and the characters of the day of the week become legible only when the dial 3 is superposed thereon.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the display of numbers, characters, figures, etc. in a watch.

[Summary of the invention]

Numbers, letters, figures, etc. are divided into two components, one element is provided on a fixed plate, and the other element is provided on a movable plate.

[Conventional technology]

Conventionally, in the display of a clock, a window is provided in a part of the dial as shown in Fig. 5, and the day or day written on the mouth wheel or day wheel placed on the bottom of the dial is displayed through the window. It was displayed through a window installed in a part of the board. [Problems to be solved by the invention] Calendar displays configured as described above have many design constraints and have become commonplace, and the calendar displays themselves cannot be said to be interior decoration. [Means for Solving the Problems] In order to provide a watch in which the display itself can serve as an interior, the present invention divides the display into two components, the first component is in the shape of a window such as a dial, and the other component is in the shape of a window such as a dial. is placed on the intermittent operating plate of the gate wheel, day wheel, etc., and the window area of the fixed plate is made small in order to minimize the covering area of the intermittent operating plate.

[For production]

In the display clock configured as described above, the second display plate rotates periodically and intermittently, so that the display is clearly displayed only in the portion that overlaps with the window of the fixed first display plate. It can be read as

〔Example〕

The present invention will be explained below with reference to FIGS. 1 to 4. On the date wheel l, a part of each of the numbers from ■ to 31 is 3.
A date display 1a is written at each equally divided position. Day wheel 2 has three English letters: MON, TUE. WED. T
HU, FRI. Part of each of SAT and StJN is 7
Day of the week display 2a is displayed in the equally divided positions.
The display surface of the date wheel 1 and the display surface of the day wheel 2 are arranged concentrically on substantially the same plane. On the dial plate 3, numbers 1 to 12 for time display are written in an annular shape at equal intervals in the center. Further, the dial plate 3 is provided with a date display window 3a on the rotation locus of the date dial 1, which shows numbers from 1 to 31 when combined with the date display 1a written on the date dial 1. Further, on the dial plate 3, when combined with the day display 2a written on the day wheel 2, it is displayed from MON to SU.
A day display window 3b showing alphabetic characters up to N is provided on the rotation locus of the day wheel 2.

As a mechanism for moving the date wheel 1 and day wheel 2, a structure shown in FIG. 6 is disclosed. That is, the date wheel 5, which rotates once a day, is engaged with the hour wheel 4, which rotates twice a day, and the hour wheel 4, which rotates twice a day, by a conversion II (not shown) and a slow gear train (not shown). is a date feed pawl 5 that engages with 31 teeth 1b provided at equal intervals on the date wheel 1 and sends one tooth per day.
a, and a day feed pawl 5b that engages with the day star wheel 2b having 7 or 14 teeth provided at equal intervals on the day wheel 2, and feeds the day star wheel 2b with 1 or 2 teeth per day. ing. The date indicator 1 is positioned by a Sunday indicator 6, and the day indicator 2 is positioned by a day indicator 7.

As is clear from FIGS. 1 to 4, it is impossible to read the display using only the day display 1a written on the date wheel 1 or the day display 2a written on the day wheel 2. Only by overlapping the dial plates 3, as shown in sections A and B in FIG. 3, can the display of, for example, 28 of the day and TUE of the day of the week be read.

In the embodiment of the present invention, the outer parts of the numbers and letters are formed in the shape of a window, and the other parts are written on the head wheel and the day wheel. Furthermore, if the color of the display and the window periphery are the same, the ease of reading and the completeness of the interior will be further improved. In addition, if a display IC other than letters or numbers is provided in a part hidden in the outer periphery as shown in Fig. 4, the display on the movable board will become more difficult to read, and the pattern will become more interesting, so it can be used for interior design. Needless to say, the level of perfection as a product will further increase.

In addition, in a clock constructed as in the present invention, the date dial I
Since most of the day wheel 2 is not covered by the dial 3, it is possible to touch the date wheel 1 and the day wheel 2 directly, so it is possible to directly touch the date wheel 1 and the day wheel 2 without providing a date and day adjustment mechanism. It can be corrected by turning.

〔Effect of the invention〕

According to the present invention, by separating characters such as the date and day of the week into two elements, it is possible to read the display only in the area of the display window where the six dial plates are provided, where the two elements overlap, and the other elements can be read. The display is illegible in this area and looks like a pattern, giving the effect that the entire area becomes an interior decoration.
