[0002]

2. Description of the Related Art As this kind of interior toy, a pair of upper and lower permanent magnets, which rotate around a horizontal axis by a driving force of a motor, are disposed at the back side of a water tank at the front side, and the rotation of the permanent magnets is performed. There is known an apparatus in which a fish body (floating body) with a built-in permanent magnet provided in an aquarium is floated by utilizing a change in a magnetic field caused by the magnetic field.

[0003]

However, this kind of conventional interior toy has the following problems.

That is, in a conventional interior toy, the operation of the fish is relatively simple because the permanent magnet is rotated at the same speed in the same direction about the horizontal axis. Because the fish body is moving by the permanent magnets arranged in the fish tank, the fish body only moves up, down, left and right in only one plane on the back side of the aquarium (there is little movement in the front-back direction). Their movements were limited to swimming, and they could not express delicately the habits of fish.

The present invention has been made in view of the above points, and has as its object to provide an interior toy having a structure that allows a floating body to perform a delicate operation.

[0006]

[0011]

According to the above means, two rotating shafts are rotated in the same direction at different rotational speeds, or
Since the rotation axis of the book is configured to rotate in the opposite direction,
The magnetic field changes subtly with time, and this change causes the floating body to move while swaying up and down or left and right. In addition, since the rotating shaft is arranged in the water tank, the floating body clings to the cover of the rotating shaft depending on the rotation speed of the rotating shaft, rubs itself, or retreats while rubbing the body, changing direction Or For example, if the floating body is a fish, it is as if a real fish is dropping insects attached to the body or eating food. Therefore, the habits of fish can be expressed in detail, which is extremely interesting. Furthermore, since the magnetic field spreads around the shaft around the rotating shaft in the water tank, the floating body will travel in a three-dimensional manner in this water tank, so that it is more interesting and the decorative value is further increased. .

First, the water tank 2 will be described. The water tank 2 is not particularly limited, but is made of plastic and is transparent. In the center of the water tank 2, a small cylinder 2
The small cylinder 22 has an open lower end. On the other hand, a top plate 22a is provided at the upper end of the small cylinder 22. The medium plate 6 provided with the notch for illumination and the coral column 3 are fitted in the small cylinder 22.
Among them, the seaweed body 5 is attached to the middle plate 6.
The coral column 3 is made of soft vinyl, though not particularly limited. A rotating shaft 9 extending in the vertical direction is disposed in the small cylinder 22. A pair of arms 24 and 25 provided on the upper and lower portions of the rotating shaft 9 so as to extend in the horizontal direction are provided. Permanent magnets 26, 26
Is attached. This pair of permanent magnets 26, 26
The arms 24, 25 are so arranged that their polarities are opposite to each other.
Attached to.

As shown in FIG. 4, the rotating shaft 9 includes an upper shaft (rotating shaft) 90 provided with the arm 24 and a lower shaft (rotating shaft) 91 provided with the arm 25. Here, the lower shaft 91 is hollow, and a gear 92 is attached to the lower end thereof. On the other hand, the lower half of the upper shaft 90 has a small diameter, the small diameter portion 90a penetrates the lower shaft 91, and a gear 93 is attached to the lower end thereof through a D cut hole 93a.
The gear 93 and the gear 92 face the inside of the mechanism box 10 (FIG. 3) disposed in the base 20.

As shown in FIG. 3, a mechanism box 10, a battery 11, a light bulb 12, and a motor 13 are arranged in the base 20. A power switch 7 and a lighting switch 8 are provided on the peripheral wall of the base 20.

In the mechanism box 10, the vertical rotating shaft 9 is provided.

Next, the structure of the fish body 4 placed in the water tank 2 will be described. The fish body 4 is not particularly limited, but its outer skin is formed of ABS resin or the like.
The outside of the fish body 4 is formed by injection molding. As shown in FIG. 6, a blow molded float 40 and a columnar permanent magnet 41 are placed inside the fish body 4. The caudal fin 4a of the fish body 4 is attached to be able to swing right and left around the longitudinal axis 42. In addition, this fish 4
In the above, a magnetic body may be provided instead of the permanent magnet 41, but since the magnetic body has no polarity, the fish body 4 does not perform a delicate operation as far as the permanent magnet is provided.

According to the accessory toy 1 of the embodiment configured as described above, the following effects can be obtained.

That is, since the upper shaft 90 and the lower shaft 91 are rotated in opposite directions, the magnetic field changes subtly with time, and this change causes the fish body 4 to sway up and down or left and right, sometimes quickly, and Sometimes, they stop and move around. Further, depending on the rotation speed, when the upper axis 90 and the lower axis 91 are relatively slow, the magnetic field spreads only in the vicinity of the coral column 3, so that the fish 4 clings to the coral column 3, and the coral column 3 flank. Or the fin 41 is rubbed, or the mouth of the coral column 3 is kissed, retreated while kissing, or the direction is changed. It is as if a real fish were dropping insects on the body or eating food. Therefore, the habits of fish can be expressed in detail, which is extremely interesting. Furthermore, since the magnetic field spreads in the radial direction inside the water tank 2 around the cover (small cylinder 22 and coral column 3) of the rotating shaft 9, the fish 4 migrates three-dimensionally in the water tank 2, More interesting and decorative values will be added.

The embodiments of the present invention have been described above. However, the present invention is not limited to the embodiments, and various modifications can be made without changing the gist of the present invention.

For example, in the above embodiment, the rotational speeds of the upper shaft 90 and the lower shaft 91 are fixed. However, the rotational speed can be switched by providing a speed change mechanism in the gear mechanism or by switching the battery. Is also good. Further, a mechanism for continuously changing the speed with the passage of time may be provided. In this way, the movement of the fish body 4 changes over time, so that it becomes more enjoyable.

In the above embodiment, the permanent magnet 26 is used as the magnet on the water tank 2 side, but an electromagnet may be used. Further, in the above-described embodiment, the vertical rotation shaft 9 is provided in the center as the cylindrical water tank 2. However, the water tank 2 may be a box type, and the vertical rotation shaft 9 may be installed in the water tank 2.
