DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fish toy that allows a plurality of tails to swim in front and rear, right and left, and particularly up and down like a live fish in a water tank.

[0002]

2. Description of the Related Art Conventionally, a large number of swimming toys have been proposed, most of which are based on magnetic force, alternate in polarity, affect fish, and swim underwater. Among the prior arts, for example, Japanese Unexamined Utility Model Publication No. Hei 2-84698 discloses a technique in which a support plate is mounted on a vertical axis rotating shaft each of which is rotated by a motor with a speed reducer, and a plurality of permanent magnets are mounted on the support plate. A tropical fish made of a material having a specific gravity of less than 1 is installed in a water tank placed above it, and a rod-shaped permanent magnet is provided at the bottom of the tropical fish so that it is suspended in water and both magnets are attracted to each other. Therefore, a device for making tropical fish swim as if it were alive has been proposed.

In Japanese Utility Model Laid-Open Publication No. 61-88796,
A swimming body having an outer shape made to imitate a fish or the like, and swimming underwater, and the swimming body is constituted by a turntable attached to an upper end of a separately formed vertical rotation axis and ,
A magnet piece is attached to the swimming body such that one pole faces outward (downward), and a plurality of N-poles and S-poles are arranged on the surface of the turntable so as to be mixed outward (upward). An underwater toy characterized in that the magnets are arranged in a dispersed manner has also been proposed.

[0004]

SUMMARY OF THE INVENTION The aforementioned proposed swimming fish toy driven by a magnet is suspended in water in a state where the swimming fish is made of a material having a smaller specific gravity and equipped with a permanent magnet. Floating in a shape means that the specific gravity is less than 1 as a whole, and reaches the water surface and floats. On the other hand, if the specific gravity is larger than 1, apart from the short time, each of them will sink and reach the water bottom and swim, and cannot stop in the middle of the water.

As one means for solving this problem, the present applicant has already proposed a device as disclosed in Japanese Utility Model Laid-Open Publication No. Sho 60-168895, and made the specific gravity of a swimming fish body less than 1 as a whole and active. By connecting a swimming fish body with a strong lifting power and a driven magnet body driven by a rotating magnet at the bottom of the water with a string, the twisting applied to the string by the rotation of the driven magnet, and the releasing action by the elasticity of the string, The length of the string was expanded and contracted so that the swimming fish could swim up and down. However, since swimming fish bodies were connected by a string, they could not swim freely.

The present invention has been made to solve the above-mentioned drawbacks of the prior art. First, in the swimming operation of the fish itself, there is a degree of freedom in the range and speed of movement, and the fish is limited to a narrow range. Secondly, their movements are varied and unpredictable, and they swim up and down and left and right as well as particularly up and down like live fish, and thirdly, they swim freely with multiple tails approaching or separated from each other. It is done for the purpose of.

[0007]

SUMMARY OF THE INVENTION A water tank having at least a part of the front surface and right and left side surfaces formed transparent is provided, and a buoyancy part and a swimming magnet are balanced, and the specific gravity of the water tank is accommodated in the water tank. A plurality of swimming fish bodies that are slightly larger than the liquid and are adjusted to sink to the bottom of the water tank at a constant sedimentation speed are accommodated in the water tank, and a ring that moves at least vertically in the side such as behind the water tank. the conveyor is mounted by attaching a support plate at predetermined intervals in the annular conveyor, the required number supporting Kahai <br/> and Bei at required intervals magnetic field generating driving magnets each support plate, for the magnetic field generating in interaction with the drive moving magnet and swimming magnet of the swimming for fish, a plurality of said in swimming for fish by applying a lifting force other forces, characterized in that to swim more tail fish as live fish to settle In the tail swimming fish toy.

[0008]

[Function] At least a vertical conveyor that moves in the vertical direction is mounted on the side, such as behind the water tank, and supporting plates are attached to the circular conveyor at required intervals, and a driving magnet for generating a magnetic field is required on each supporting plate. and the supporting Kahai Bei the required number at intervals, since the upper and lower longitudinally field generating driving magnet moves every moment changes the magnetic field with respect to the aquarium, which is not uniform impact on multiple tail fish body, the mobile The resulting magnet action works by interacting with the fish's swimming magnet, so the movement of the swimming fish is
It swims like a live fish, full of variety and unnaturalness.
