Abstract

PURPOSE:To enjoy the eye of a viewing person by the change of the patterns preliminarily applied to both of an hr hand and a min hand indicating a time, by constituting the title apparatus of an hr hand pipe, a min hand pipe, an hr hand holder, a min hand, the first tooth part, the first pinion, the second tooth part and the second pinion. CONSTITUTION:When an hr hand pipe 3 is rotated around its axis, the hr hand 3b held to an hr hand holder 3a is rotated around the axis of the hr hand pipe 3 and the first tooth part 5 on a dial 2 is meshed with the first pinion 6 of the hr hand 3b and, therefore, the hr hand 3b itself is rotated around the axis thereof. In the same way, when a min hand 4 is rotated around its axis, the min hand 4b held to a min hand holder 4a is rotated around the axis of the min hand pipe 4 and the second tooth part 7 on the hr hand holder 3a is meshed with the second pinion 8 of the min hand 4b and, therefore, the min hand 4b itself is rotate around the axis thereof. Therefore, the patterns applied to both of the hr hand 3b and the min hand 4b are changed with the elapse of time.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a timepiece device.

[Prior Art] In a conventional timepiece device, the hour hand and minute hand are directly attached to an hour hand pipe and a minute hand pipe, respectively, which are coaxially fitted and protrude through a dial plate, and display the time.

[Problem to be solved] In conventional clock devices, the color of the hour and minute hands for displaying the time is constant, so there is a problem that there is little change in color and it lacks aesthetic effect. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a timepiece device that is simple in construction and has a high aesthetic effect by showing the color changes of the hour and minute hands.

[Means for Solving the Problems] In order to achieve the above object, the timepiece device of the present invention includes an hour hand pipe and a minute hand pipe that are coaxially fitted and protrude through the dial, and the hour hand pipe and the minute hand pipe. An hour hand holder and a minute hand holder are attached to each tip of the minute hand pipe, and a cylinder extends in the radial direction of both pipes and is held rotatably about its axis by the hour hand holder and minute hand holder. Shaft-shaped hour and minute hands, a first tooth portion fixedly disposed on the dial concentrically with the two pipes, and integrally formed with the hour hand so as to mesh with the first tooth portion. a first pinion formed integrally with the hour hand holder, a second tooth portion integrally formed on the hour hand holder concentrically with the two pipes, and a second tooth portion integrally formed with the minute hand so as to mesh with the second tooth portion. It is equipped with a certain second pinion.

[Operation] According to the timepiece device configured as described above, the hour hand and the minute hand rotate about their respective axes as time passes.

[Example] Examples will be described with reference to the drawings.

As shown in the first diagram, a dial plate 2 is disposed on the front side of a watch body 1, and an hour hand holder 3a and a minute hand holder 4a are attached to the tips of an hour hand vibrator 3 and a minute hand vibrator 4 that protrude through the dial plate 2, respectively. is installed. As shown in FIGS. 2 and 3, the hour hand holder 3a holds the cylindrical-shaft-shaped hour hand 3b, and the minute hand holder 4a holds the cylindrical-shaft-shaped minute hand 4b so that they can rotate freely around their axes. There is. A first tooth portion 5 is fixedly disposed on the dial 2 concentrically with both pipes 3 and 4, and meshes with a first pinion 6 formed integrally with the hour hand 3b. Furthermore, a second tooth portion 7 is integrally formed on the hour hand holder 3a concentrically with both pipes 3 and 4, and meshes with a second pinion 8 that is integrally formed with the minute hand 4b. Note that the hour hand 3b and the minute hand 4b actually have a pattern, although not shown.

Next, the operation will be explained. When the hour hand vibrator 3 rotates around its axis, the hour hand 3b held by the hour hand holder 3a rotates around the axis of the hour hand vibrator 3, and the first tooth 5 on the dial 2 and the hour hand 3b 1st pinion 6
Since the two are in mesh with each other, the hour hand 3b rotates by itself around its axis.

Similarly, when the minute hand pipe 4 rotates around its axis, the minute hand 4b held in the minute hand holder 4a rotates around the axis of the minute hand vibrator 4, and the hour hand holder 3a
Since the upper second tooth portion 7 and the second pinion 8 of the minute hand 4b mesh with each other, the minute hand 4b rotates by itself about its axis. Therefore, the patterns applied to the hour hand 3b and the minute hand 4b change over time.

In this embodiment, the dial plate 2 and the first tooth portion 5 are constructed as separate members, but they may be integrally formed. Furthermore, the hour hand holder 3a and the second tooth portion 7 may be constructed from separate members instead of being integrally formed.

r effect] Since the present invention is configured as described above, the hour hand and the minute hand display the time while rotating on their own axis as time passes, and the patterns previously applied to the hour hand and the minute hand change. Pleasant to the eyes of the beholder. Furthermore, adding color to this pattern provides color variation, which greatly contributes to enhancing the aesthetic effect of the clock device.
