EXAMPLE As shown in FIGS. 1 to 5, a decorative pendulum device K
Includes a main pendulum 2 swingably provided on the support plate 1, a driven pendulum 3 and a pendulum driving means M which are swingably attached to the main pendulum.

The main pendulum 2 has a lower half portion of a central member 2a formed in a ring shape when viewed from the front, and a rod portion 2b integrally formed with the central member 2a. The rod portion 2b is formed in a state where the portion of the windpipe of the wind instrument is meandering, and the portion of the blowout portion projects outward from the lower left portion of the central member 2a and is positioned upward to the tip portion bent into an L shape. It is provided to do so.

A decorative plate 2c having a shape in which a doll is placed on a large ball is screwed and fixed to a tip portion of a portion of the rod portion 2b corresponding to the blowout port. The right half of the shape of the wind instrument of the rod portion 2b is placed horizontally at the front of the central member 2a when viewed from the front, bent in a U shape, and further bent rearward from the rear of the central member to the right. An overhang is formed, and a portion corresponding to the sound emission opening is formed at the tip of the overhang so as to form an upper right angle of about 30 °.

At a portion corresponding to the sound output port of the rod portion 2b, a decorative plate 2d having a shape in which a doll sits in front of the ball is fixed by screws. A driven pendulum 3 is swingably attached to the decorative plate 2d.

When the upper half of the driven pendulum 3 is viewed from the front,
The doll is shaped like a balloon,
When viewed from the rear side, as shown in FIG. 2, a thin plate-like driven swing rod 8 is swingably attached to the back surface of the decorative plate 2d of the main pendulum 2 via the support shaft 7. The driven swing rod 8 can swing about the support shaft 7 via a driven pendulum bearing 9. A mounting screw 10 is attached to the upper end of the driven swing rod 8.
The follower decorative member 11 is attached through (see FIG. 3). Thus, the main pendulum 2 and the driven pendulum 3 are decorative pendulums that also serve as decorations.

As shown in FIG. 4, the main pendulum 2 is a support plate 1
It is swingably supported by a supporting member 1a protruding from the bearing via a bearing member 2e. The support portion of the support member 1a is formed at the knife edge, and the recessed portion of the bearing member 2e engages with this to minimize the frictional resistance (see FIGS. 1 and 2).

As shown in FIG. 1, the rod portion 2b of the main pendulum 2 is shown.
A driving magnet 5 that constitutes the pendulum driving means M is attached to the back side of the curved portion that protrudes to the left. The pendulum driving means M includes a driving magnet 5, a circuit board 4 attached to the support plate 1, and a drive coil 4a mounted on the circuit board. The drive coil 4a is provided at a position facing the swing locus of the drive magnet 5, and the main pendulum is kept constant by alternately applying a voltage to a drive circuit (not shown) formed on the circuit board 4. It oscillates in a cycle.

As shown in FIGS. 2 and 3, a first permanent magnet 12 is provided on the rear surface of the lower end portion of the driven swing rod 8. Further, a second permanent magnet 6 is provided on the front surface side of the support plate 1 located below the first permanent magnet 12. When the first and second permanent magnets face each other, they repel each other,
That is, they are provided so that the same polarities face each other when they approach each other.

Therefore, when the main pendulum 2 swings, the first
When the permanent magnet 12 of FIG. 2 approaches the second permanent magnet 6, the first permanent magnet 12 swings around the support shaft 7 by the repulsive force of the second permanent magnet 6. At this time, the swinging cycle of the main pendulum 2 is disturbed due to the position of the first permanent magnet 12 or the angle of the driven swing rod 8, etc.
The driven pendulum 3 and the driven pendulum 3 have a surprising and interesting movement.

The movement of the driven pendulum 3 is such that the two permanent magnets 6, 1
Since it can be different depending on the combination of the mounting position of 2, the strength of the magnetic force, the length of the swing rod, etc., it can be set so that each ornamental pendulum device moves differently. Thus, the decorative pendulum device of the present invention is a swing pendulum device in which the main pendulum 2 and the driven pendulum 3 can swing.

The driven pendulum 3 moves with different oscillating angles in different oscillating directions for each cycle of the main pendulum 2, and the periodical movement is repeated for several cycles. Therefore, the period contrast of the driven pendulum 3 with respect to the main pendulum 2 can range from 1 to a random value close to infinity.

An example of such a movement of the driven pendulum will be described. In this case, the mass of the driven pendulum 3 needs to be small enough not to change the swing motion of the main pendulum 2. Assuming that the total period of the decorative pendulum including the main pendulum 2 and the driven pendulum 3 is T0, and the period of the driven pendulum is T1, T1 is (1 to
1.2) When adjusted to about T0, the driven pendulum slowly oscillates for one cycle in synchronization with the cycle of the main pendulum. In the most stable state, the driven pendulum oscillates once for one cycle of the main pendulum, and its movement oscillates left and right with three cycles as one cycle.

As another example of the cycle of the driven pendulum, the oscillating circumference T1 of the driven pendulum is adjusted to about 0.5T0 so that the driven pendulum oscillates two reciprocations with respect to one reciprocation of the main pendulum. You can also do it.

FIG. 5 shows, in order, an example of the movement of the driven pendulum 3 in relation to the main pendulum 2, and shows that the driven pendulum swings in the order of the numbers circled on the left side of each drawing. This means that the number 1 is returned to the number 1 again after the number 12, and the driven pendulum 3 is 1 for every 6 cycles of the main pendulum 2.
It shows that the oscillating motion of the cycle is performed.

Although the above-mentioned decorative pendulum device is described as being provided with the driven pendulum only at one end of the main pendulum, the driven pendulum may be provided at both ends of the main pendulum. In FIG. 6, the decorative plate 2c provided at the left end of the main pendulum 2 in the above-described embodiment is replaced with a decorative plate 22d symmetrical to the decorative plate 2d at the right end, and the driven pendulum 3 at the right end is symmetrical to the second follower. A pendulum 23 is provided. Main pendulum 2
On the back surface of the decorative plate 22d of the
The driven swing rod 28 is attached swingably. A third permanent magnet (not shown) is provided on the rear surface side of the lower end portion of the second driven swing rod 28, and on the front surface side of the support plate 1 located below the third permanent magnet. , The fourth permanent magnet 2
6 is provided. The third and fourth permanent magnets are provided in the same relationship as the first and second permanent magnets so as to repel each other when they face each other. As a result, the left and right driven pendulums 3 and 23 oscillate along with the oscillating main pendulum 2, but it is also possible to make different movements by arbitrarily setting the mounting positions of the permanent magnets. So it will be entertaining.

It is desirable that any of the pendulums 2, 3 and 23 be given an arbitrary design to be a decorative pendulum that meets the taste of the consumer. Especially driven pendulum 3,23
It is desirable to consider the balance in the left and right designs of the driven decorative members 11 and 31.

FIG. 7 shows a front state of a watch with a decorative pendulum device to which the decorative pendulum device according to the present invention is attached. A dial 62 and a pointer 63 are provided on the upper front surface of an oval clock frame 61, and a decorative pendulum device K shown in FIG. 1 is provided at a slightly retracted position below the dial.
The upper part of the central member 2a of the decorative pendulum device is hidden behind the lower part of the dial 62. Further, the lower portion of the central member 2a of the main pendulum 2 described above with reference to FIG. 2, the circuit board 4a, and the second permanent magnet 12 are made invisible from the front by the blindfold portion 65 provided in the lower portion of the entire glass 64. is there. In front of the central portion of the central member 2a, there is provided a blindfolding ornament 66 for blinding the supporting plate 1 and the supporting member 1a described above with reference to FIGS. The blindfold decoration 66 is
By designing the key shape of the wind instrument, it is in harmony with the design of the ornamental pendulum device. In this manner, the decorative pendulum device and the timepiece are designed in harmony with each other, and in addition to the swing of the main pendulum, the driven pendulum makes an unexpected movement, thereby increasing the added value of the timepiece.

[0027]

As described above, according to the present invention, the driven pendulum provided on the main pendulum is caused to make a complicated movement by utilizing the repulsive force of the permanent magnet, so that a swinging pendulum device rich in interest can be provided. The driven pendulum can obtain various movements depending on the strength of the repulsive force of the pair of permanent magnets, the length of the driven swing rod, or the combination of the mounting positions. As a result, the driven pendulum can be swung in accordance with the design of the decoration device, so that a decoration pendulum device rich in variety can be obtained. By attaching this to a watch, a watch with a decorative pendulum device having a high added value can be obtained.
