BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pendulum of a pendulum timepiece, and more particularly to a pendulum device for enhancing a decorative effect.

[0002]

2. Description of the Related Art In recent years, even when electronic circuits for clock circuits have progressed, timepieces having a conventional pendulum are preferred, and a drive circuit for driving a pendulum for decoration is provided in addition to a clock circuit using a crystal oscillator or the like. The pendulum is driven separately from the movement of the hands of the timepiece. And, since this pendulum is provided as a decoration separately from the hand movement, not only the pendulum that follows the conventional pendulum style but also a new decorative effect is desired (for example, the fairness). 1-9031
No. 1-9032), there has been a demand for shapes and movements that have never existed before.

[0003]

In many cases, the conventional decorative pendulum is designed to be hung below the timepiece body and oscillated left and right to enhance the decorative effect.
Today, the proliferation of similar shapes has made it difficult to develop pendulums that have a high decorative effect. Therefore, it is a challenge today to combine unprecedented movement with that of a pendulum to achieve a decorative effect with a relatively simple pendulum mechanism.

[0004]

According to the present invention, there is provided a first pendulum having a horizontal portion and a vertical portion, a horizontal decoration portion arranged on an extension of the horizontal portion of the first pendulum, and a fulcrum from the horizontal decoration portion. And a second pendulum having a balancer at a different position, and an engaging portion for engaging the first pendulum and the second pendulum is formed between the fulcrum of the first pendulum and the fulcrum of the second pendulum.

[0005]

[Operation] Since the present invention is provided with the first pendulum having the horizontal portion and the vertical portion, the horizontal portion of the first pendulum is vertically moved by swinging the vertical portion of the first pendulum to the left and right. Can be rocked to. Further, since the first pendulum is engaged with the second pendulum by the engaging portion, the second pendulum can be swung by the swing of the first pendulum.
