Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a time signal clock equipped with a time signal wheel, and more particularly, to a structure for indicating the setting of the time signal hand of a time signal clock.

(Prior Art) When attaching a pointer to a time signal clock, the pointer is attached in accordance with the time signal, and it is required that the time signal can be easily and reliably confirmed. In response to this, the applicant has previously
He proposed the idea of Utility Model Application No. 60-29294.

This is equipped with a time reporting time indicator on a time reporting car that rotates once every 12 hours, and a see-through part that looks into the indicator.
The time signal clock was provided on a cover that covered the car corresponding to the time signal.

(Problem to be solved by the invention) However, in the above invention, when an indicator appears on the transparent part, the pointer is attached to match the indicator on the dial plate based on the number of the indicator, so the dial and the pointer are There were times when a slight positional shift occurred between the two. Therefore, in order to avoid such positional deviations, the work must be done carefully and carefully, leaving room for improvement in terms of workability.

(Means for Solving the Problems) The present invention takes the above-mentioned idea one step further and aims to provide a time signal clock in which the hands can be attached without causing any misalignment between the dial and the hands. be.

That is, the present invention provides a time signal clock in which a time indicator is provided on a time signal car that rotates once every 12 hours, and a see-through portion for viewing the indicator is provided in a cover that covers the time signal car. The hour wheel is provided with scales at predetermined intervals, a see-through part through which the scale can be seen is provided on a cover that covers the date wheel, and a mark is provided on the outer periphery of the scale see-through part. The scale is provided so that when the lever is lowered, the scale on the minute wheel and the mark on the scale see-through part match.

(Example) The present invention will be explained below based on the illustrated example.

Fig. 1 is an external perspective view of a movement showing an embodiment of the present invention, Fig. 2 is a plan view showing a part of the structure of the movement, and Fig. 3 is a longitudinal cross-sectional view showing the developed gear train. The corresponding time signal wheel 1 is a rotating body that rotates once every 12 hours, and is provided with the numeral 3 as a time signal indicator, similar to the above-described invention.

The time signal wheel 1 is driven by an hour wheel 7 that meshes with a gear 5 provided on the same axis, and a driving force is applied from a diagonal wheel 11 that meshes with a minute hand pinion 9. A conductive portion 13 made of copper foil is patterned on the surface of the time signal wheel 1, and this pattern has 12 contact portions 13a for causing the time signal clock to strike each hour on the hour. A contact plate is installed near the time signal wheel 1, and the contact plate has a plurality of elastic contact levers 15 connected to the conductive portion 13.
It is configured to extend upward and press the conductive part 13. A cover 17 covering the time signal wheel 1 is provided with a see-through portion 19 for viewing the numeral 3.

In the embodiment, as shown in FIG.
When the contact lever 23 falls into the position 1, a reed switch (not shown) is activated, and the time signal position is detected by the contact lever 15 in contact with the conductive portion 13, thereby generating a time signal sound.

Further, in the present invention, scales 11a are provided at predetermined intervals on the dial 11 of the day, and a cover 17 that covers the dial 11 of the day is provided with a see-through portion 25 through which the scale 11a is viewed.
Further, a mark 25a is provided on the outer periphery of the scale transparent portion 25.

In the embodiment, the cover that covers the dial 11 is the same as the cover that covers the time signal wheel 1, and therefore the see-through section 19 and the scale see-through section 25 can be conveniently viewed from the same direction. It is.

Further, in the present invention, when the contact lever 23 falls into the minute hand cam 21, the scale 11a of the minute wheel 11 and the mark 25a of the scale see-through part 25 are provided so as to match.

In the time signal clock of the present invention configured as described above, the time signal wheel 1 is rotated by the driving force transmitted through the hour wheel 11 and the hour wheel 7.
During one rotation of the contact lever 15, the contact lever 15 appropriately contacts the patterned contact portion 13a, and sends a time signal to the IC through the contact plate. For example, as in the example,
When a 6 o'clock time signal is sent, the number 3 of "6" appears on the transparent section 19. On the other hand, the scale transparent part 2
5, look at the scale 11a of the sun wheel 11 and mark the scale 1.
When 1a coincides with the mark 25a of the transparent scale part 25, 6 is on the hour, so confirm this and set the hand to 6 o'clock and attach it.

(Effect of the invention) As explained above, this invention improves the time reporting time index.
In the time signal clock, which is provided on a time signal wheel that rotates once every 12 hours, and in which a see-through part through which the indicator can be seen is provided on a cover that covers the time signal wheel, a scale at a predetermined interval is provided on the date wheel. Further, a transparent part through which the scale can be seen is provided on a cover that covers the rear wheel of the day, and a mark is further provided on the outer periphery of the scale transparent part,
When the contact lever falls into the minute hand cam, the scale on the minute wheel and the mark on the transparent scale section are provided so that they match, so the scale on the minute hand wheel and the mark on the transparent scale section are aligned. It is the hour when they match,
Therefore, since it is only necessary to attach the pointer at that position, it is possible to avoid positional deviations that occur due to subtle differences in the conventional way of grasping the hour, that is, misalignment between the dial and the pointer. The pointer can be attached to the pointer, and the workability of attaching the pointer can be improved.
