Description

[Detailed description of the invention] The present invention relates to the improvement of a decorative pendulum device attached to a watch, and in particular, when one of a plurality of pendulums is oscillated at a predetermined period, other pendulums are is capable of swinging at a predetermined period, and is characterized in that at least the driving pendulum and the driven pendulum swing in different directions.

Conventionally, in a decorative pendulum device for a clock, the pendulum is 1
There is only one pendulum, and a configuration in which this one pendulum swings in the left-right direction or the front-back direction at a predetermined period is known. This type of pendulum device lacked freshness in its dynamic decorative effect and lacked interest in design.

In recent years, pendulum clocks with decorative pendulums have been in high demand for interior design, and there has been a desire to provide a decorative pendulum device with a novel dynamic decorative effect.

The present invention was developed in view of the above-mentioned conventional problems, and its purpose is to enable a plurality of pendulums to swing at a predetermined period in conjunction with the driving of one pendulum, and at least to It is an object of the present invention to provide a pendulum device in which a pendulum and a driven pendulum swing in different directions.

In order to achieve this purpose, the present invention includes at least two support parts arranged in parallel at a predetermined distance on a support plate, and a swinging ball and a swinging rod that are swingably supported by the support parts. at least two swinging parts having a structure that is configured to be able to swing integrally with any one of the swinging parts, and a part of which is arranged close to another swinging part. A swinging rod comprising an engageable elastic member and a swinging drive device capable of continuously swinging a predetermined swinging rod with respect to a support plate, and swingingly driven by the swinging drive device. The oscillating motion of the oscillating section provided with this is transmitted to the other oscillating section via the elastic member, thereby making it possible to oscillate other swinging rods.

The present invention will be explained below based on the embodiments shown in the drawings.

1 to 3 show a pendulum device according to the present invention, in which two knife edges 4 and 6 are provided on the upper surface of a support plate 2 in which a clock train is housed. A mounting portion 12 having a V-groove 8 is swingably supported on the knife edge 4, and a mounting portion 14 having a V-groove 10 is swingably supported on the knife edge 6. An L-shaped elastic member 16 for swinging and biasing the mounting part 14 is fixed to the mounting part 12, and the end of the elastic member 16 is placed on the knife edge 4 side as shown in FIG. Placement section 1 near
4 and is arranged to engage with the corner end 18 of 4. As a result, the mounting portion 14 is supported by the elastic member 16 at its corner end 1.
8 can be easily swung relative to the knife edge 6 by being pressed.

A swinging rod 20 including a clock display pipe 22 and hanging down in the vertical direction is integrally formed on the mounting portion 12. The vicinity of the display pipe 22 of the swinging rod 20 is curved into a substantially semicircular shape, so that the swinging rod 20 can swing without coming into contact with the display pipe 22. Further, a permanent magnet 24 and a swinging ball 26 are fixed to the swinging rod 20, and the permanent magnet 24 is arranged to overlap with a driving coil 28 fixed to the support plate 2, as shown in FIG. It constitutes a driving device. Although not shown, the drive coil 28 is connected to a drive circuit and a power source mounted on the support plate 2, and is electromagnetically coupled to the permanent magnet 24, thereby making it possible to swing the swinging rod 20 at a predetermined period.

A swinging rod 30 including a display pipe 22 and hanging down in the vertical direction is integrally molded on the mounting portion 14, and the vicinity of the display pipe 22 of the swinging rod 30 is curved into a substantially semicircular shape. The swinging rod 30 can swing without coming into contact with the display pipe 22. Further, a swinging ball 32 is fixed to the tip of the swinging rod 30, and the swinging ball 32 is arranged to overlap the swinging ball 26 described above.

The illustrated embodiment is constructed as described above, and its effects will now be described.

4 to 6 are explanatory views of the operation of the pendulum device according to the present invention. As shown in FIG. 4, when the permanent magnet 24 is moved in the direction of arrow A by an electromagnetic action such as an attractive force or a repulsive force generated between the permanent magnet 24 and the drive coil 28, the mounting portion 12
The end of the elastic member 16 is located at the corner end 18 of the mounting section 14.
Press down in the direction shown. As a result, the mounting section 1
4 tilts in the direction of arrow A, and swinging rod 30 moves in the direction of arrow B. Next, the swinging rods 20 and 30 move in opposite directions due to the inertial force caused by the weight of each swinging ball 26 and 32, passing through the state shown in FIG.
It will be in the state shown in the figure. Thereafter, each swinging rod 20, 30 moves in the opposite direction again due to the above-mentioned inertia force. In this way, the swinging rod 20 has a permanent magnet 24
The oscillating action is energized by the electromagnetic action that occurs between the drive coil 28 and the drive coil 28. On the other hand, the swinging rod 30 swings as the swinging motion of the swinging rod 20 is transmitted to the mounting section 14 via the elastic member 16 of the mounting section 12, and the moving direction of the swinging rod 30 is the direction of movement of the swinging rod 20. It is different from.

In the illustrated embodiment, an elastic member 16 is coupled to the mounting section 12, and the swinging motion of the mounting section 12 is transmitted to the mounting section 14 via the elastic member 16, so that the transmission is smooth. When the placing parts 12 and 14 are moved in the same direction by an external force, the elastic member 16 is elastically deformed, thereby preventing damage to the placing parts 12 and 14. Furthermore, although the swing rods 20 and 30 are set to have the same length in the illustrated embodiment, they may have different lengths. Furthermore, in the illustrated embodiment, the mounting portions 12 and 14 having V grooves 8 and 10 are placed on the knife edges 4 and 6, but this is different from the configuration in which the mounting portions 12 and 14 having the knife edges are placed on the seats having the V grooves 8 and 10. The configuration may be such that a placing section is placed thereon.

As explained above, according to the present invention, when one of the plurality of pendulums is driven, the other pendulums swing at a predetermined period. Further, since the pendulum on the driving side and the pendulum on the driven side move in opposite directions, it is possible to provide a novel pendulum device that has never existed before. As a result, the pendulum device according to the present invention has a dynamic decorative effect and is excellent in interior design, and has extremely high practical effects. Furthermore, in this invention, the driven pendulum is linked with the driving pendulum via the elastic member, so even if the driving pendulum and the driven pendulum are actuated in the same direction by an external force, each pendulum will not swing. No parts will be damaged.
