Abstract

PURPOSE:To easily read date and a day of week, and to make the titled timepiece thin by fixing a calendar hand to a date indicator which has been provided on the lower part of a ring-shaped dial attached to the center part, and stretching this calendar hand from between a ring-shaped dial and an inside dial. CONSTITUTION:A ring-shaped dial 1 provided with a space whose size exceeds a turning area of an hour hand 13 is attached to a center part. A calendar hand 9 is fixed to a date indicator 7 which has been provided on the lower part of this dial 1. This calendar hand 9 is stretched out from between the ring-shaped dial 1 and an inside dial 4 for filling up its space, and a date which has been put onto its surface is indicated.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a portable watch with a calendar.

(Prior Art) A portable watch with a calendar generally has a date wheel or a mouth wheel and a day wheel disposed below the dial, and these are exposed through a window hole provided in a portion of the periphery of the dial.

For this reason, conventional portable watches with calendars had to have hour, minute, and second hands and a date wheel placed above and below the dial, which not only unnecessarily increased the total thickness of the watch, but also Since it is necessary to read the fine letters below through the window hole, there are disadvantages such as the need for auxiliary means for reading, such as a lens formed on a part of the glass.

(Objective) The present invention was made in view of the above-mentioned disadvantages, and its object is to provide an improved portable watch with a calendar that allows easy reading of the date and day of the week and that can be made as thin as possible. It is about providing.

(Means for Achieving the Object) That is, in order to achieve the object, the present invention has a time indicator and a date on the periphery, and a blank space in the center that is at least larger than the rotating area of the hour hand. The provided ring-shaped dial plate and the inner dial plate, which is large enough to fill the above-mentioned space of the ring-shaped dial plate, are attached so that they are almost on the same plane, and a calendar is attached to the spout located below both dial plates. This portable timepiece with a calendar has a fixed pointer and extends the calendar pointer through the gap between the two dial plates and onto the ring-shaped dial plate.

(Example) The details of the present invention will be described below based on illustrated examples.

FIG. 1 shows an embodiment of the present invention, and the reference numeral 1 in the figure is a ring-shaped dial plate whose central part is punched out as a circular space larger than the rotating area of the hour hand. teeth,
As a dial for time and date display, the time indicator 2 is on the inner circumference of the surface, and the date 3 from 1 to 31 is on the outer circumference.
is attached and fixed to the inner stage 11 of the body 10,
Further, in the circular space of this ring-shaped dial plate 1, an inner dial plate 4 filling this part is integrally attached to the main plate 2 with a dowel 5 so as to form the same plane.

How to use: Below these dials 1.4, there is installed a well-known date wheel 7 that moves once a day for one day using a date wheel and a date dial (not shown). A bottle 8 embedded in a part of the dial 1.4 protrudes above the dial 1.4 through a ring-shaped slit 6 formed between the swing-shaped dial 1 and the inner dial 4, and roughly touches its protruding end. A calendar pointer 9 that rotates at 18 is fixed to the ring-shaped dial 1, and the 31 date marks 3 attached to the outer periphery of the ring-shaped dial 1 are indicated by the forked tips of the calendar pointer 9. It is configured to instruct one in sequence.

In addition, the symbols 13, 14, and 15 in the figure indicate the hour hand, minute hand, and second hand, and the 1st indicates the spout holder, respectively.

According to this embodiment, the ring-shaped dial plate 1 and the inner dial plate 4
The bottle 8 on the spout wheel 7 is made to protrude from the ring-shaped slit 6 between the two, and a calendar pointer 9 along the ring-shaped dial 1 is attached thereto. Not only can the date of the day be read out, but by rotating the calendar hand 9 and the hour hand 13 rotating within the same plane, the total thickness of the watch can be reduced accordingly.

The embodiment shown in Fig. 3.4 has dates 23 from 1 to 31 on the outer periphery of the ring-shaped dial 2 and a large number of window holes 2o corresponding to each date 23. On the other hand, a day plate 39 is provided below the dial 2 which engages with the pinion 38 on the crown shaft 37, and the day of the week marked on the day plate 39 is made to face each window hole 20. In the figure, reference numeral 24 indicates an inner dial plate, 27 a date wheel, and 29 a calendar pointer fixed to a bin 28 on the date wheel 27, all of which are the same as those described in the first embodiment. Since it is configured as follows, further explanation will be omitted.

In this embodiment, if the crown is operated in advance at the beginning of the month to make the day of the week that appears through the window hole 2o coincide with the date of the month, the date and day of the week will be displayed simultaneously by the calendar pointer 29 on the date wheel 27. be able to.

(Effects) As described above, according to the present invention, a ring-shaped dial plate is installed in the center with a space larger than the rotation area VT of the hour hand, and a date dial is provided below the dial plate. A calendar pointer is fixed to the dial, and this calendar pointer is extended over the ring-shaped dial through the gate between the ring-shaped dial and the inner dial that fills the space, and the date marked on that surface is indicated. Because of this structure, even when the date characters are extremely small, it is not only possible to easily read the current date from these arrangements and the position of the calendar pointer.
Since this calendar hand can be rotated at least in the same plane as the hour hand, it is possible to reduce the overlap of this type of calendar hand and make the watch body as thin as possible.
