[Technical field to which the invention belongs]

 The present invention relates to a jellyfish-shaped underwater toy.

[0002]

[Prior art]

 An underwater toy of this type is known from Japanese Patent No. 3072354. It has a shape that resembles a jellyfish, has a solar panel on top, rotates the motor with the power generated by the solar panel, transmits the torque of the motor to the screw provided below the toy, and rotates the screw. This allows the water toy to float in the water without sinking.

By the way, since the solar panel has a flat shape and is arranged on the upper part of the toy body, in order to make it jelly-shaped, it is necessary to cover the upper part with a convex plate whose top is swollen.

According to this configuration, a space is formed between the solar panel and the convex plate, and when air is sealed in this space, buoyancy increases and it is difficult to sink, so a circle is formed at the top of the convex plate. By forming the holes, the water in the water tank may be filled inside.

[0005]

[Problems to be solved by the invention]

 However, even if a circular hole is formed at the top of the convex plate, when the upper end of the underwater toy contacts the water surface, the surface tension of the water surface acts and the water surface acts to pull up the underwater toy. There was a problem that it remained floating.

An object of the present invention is to solve the above problems and to provide an underwater toy that can be reliably sunk again even if the underwater toy floats on the water surface.

[0007]

Means for Solving the Problems In order to solve the above problems, the underwater toy according to the present invention has a shape simulating a jellyfish and has the following requirements. (B) The body of the toy shall include a motor and a screw that floats in the water by the motor. (B) The upper part of the body of the toy is covered with a circular convex plate whose top is swollen, and inside the circular convex plate. A space is formed. (C) A plurality of long holes are formed to penetrate around the top of the circular convex plate. (D) A plurality of projecting pieces are erected near the top of the convex plate. is being done

It is preferable that each of the holes is a long hole, which is formed to be spirally curved from the top, and the protruding piece is formed to rise from an outer end of each of the long holes.

It is preferable that the projecting piece and the hole are formed by cutting and raising the circular convex plate.

Further, it is preferable that the motor is mounted in a closed space of the toy main body, and buoyancy is generated by the closed space.

[0011]

[Embodiment of the invention]

 Fig. 1 is a perspective view of an underwater toy migrating underwater simulating the shape of a jellyfish. Fig. 2 is a longitudinal sectional view of the toy body 1. The toy body 1 is waterproofed with transparent plastic, and a solar panel 2 is sealed on the top. In addition, it is possible to receive light from a lighting means (not shown) provided at the upper part of the water tank in which the underwater toy is placed.

In the center of the toy main body 1, a motor 3 that rotates by electric power generated by the solar panel 2 and a reduction gear 4 that reduces the rotation of its output shaft are arranged. A donut-shaped inner magnet 6 having N and S poles on the same surface is fixed. The motor 3 and the inner magnet 6 are mounted in a closed space of the toy main body 1 so that buoyancy is generated by the closed space. Therefore, a separate float such as styrene foam is not required. Styrofoam, although slow, absorbs water, and is not preferred because the weight of the underwater toy itself gradually increases.

On the other hand, a donut-shaped outer magnet 7 is disposed below the outside of the toy body 1 at a position facing the inner magnet 6, and a vertical shaft 8 projects from the center of the outer magnet 7. The screw 9 is provided at the tip. Thereby, the motor 3 can rotate the screw 9 without being affected by water.

Next, the upper part of the toy main body 1 has a shape imitating an umbrella of a jellyfish head. First, the top is covered with a bulged transparent convex plate 10 made of synthetic resin, and a space is formed inside the convex plate 10.

Further, a plurality of circular holes 11 are formed in a peripheral portion of the convex plate 10, and a plurality of long holes 12 are formed radially around the top portion. Each elongated hole 12 is formed in a spiral shape from the top, and a projecting piece 13 having substantially the same shape as the elongated hole 12 is formed obliquely upright on the elongated hole 12 from the outer end of each elongated hole 12. ing.

The projecting piece 13 and the long hole 12 may be formed by cutting and raising the circular convex plate 10.

At the periphery of the convex plate 10, a soft thin film 14 imitating jellyfish is provided via a soft and slightly rigid transparent support sheet 14 a. A plurality of small magnets 15 are attached to the inner peripheral portion of the thin film 14, and these small magnets 15 are arranged near the outer magnet 7.

A plurality of feet 16 are provided below the toy body 1. Further, a shaft 17 is formed below the central portion of the toy body 1, and a plurality of weight plates 18 are detachably provided on the shaft 17. It is preferable that the weight is adjusted by the weight plate 18 so that the toy body 1 slightly sinks in water.

According to the above configuration, when the underwater toy is put in water, water enters through the circular hole on the periphery of the head and the long hole 12 around the top. When the solar panel 2 receives the illumination light, electric power is generated, the motor 3 rotates, and the inner magnet 6 rotates at the same time. When the magnet 6 rotates, the magnetic field changes. Therefore, a rotational force is transmitted to the outer magnet 7 in synchronization with the rotation, and the screw 9 rotates. For this reason, underwater toys are forced to float underwater. Since the underwater toy is adjusted to sink by the weight plate 18, the underwater toy moves slowly in the water. At this time, the small magnet 15 on the inner peripheral edge of the thin film 14 fluctuates because the small magnet 15 receives an attractive force and a repulsive force alternately due to a change in the magnetic field due to the rotation of the magnet 7. As a result, the thin film 14 pulsates, and the underwater toy can realize more biological movement.

When the underwater toy floats on the water surface W and then receives a force such that the illumination light goes out, such as when the underwater toy sinks again, the underwater toy normally receives the surface tension of the water surface. That is, since the protruding pieces 13 are formed upright from the outer end of each long hole 12, the protruding pieces 13 protrude from the water surface, so that the surface tension effect is hindered. For this reason, the underwater toy can surely sink again.

Since the protruding piece 13 is formed such that each of the long holes 12 is spirally curved from the top, the protruding piece 13 is affected by the water flow, and the underwater toy moves slowly while floating under the influence of the water flow. So the movement is not simple.

Although the underwater toy uses a solar panel as a power source, a battery may be used. Also in this case, since the battery is arranged on the upper part of the head of the underwater toy, a convex plate is attached on the upper part, and a long hole or the like is also formed.

[0023]

[Effect of the invention]

 According to the invention of claim 1, when the underwater toy is forced to sink again, such as when the illumination light is turned off after the underwater toy floats on the surface of the water, the surface of the water toy is usually turned off. Although it is subjected to surface tension, a plurality of protruding pieces are formed upright near the top, and the protruding pieces protrude from the water surface, so that the surface tension effect is hindered. For this reason, the underwater toy can surely sink again.

According to the invention of claim 2, since the projecting piece is affected by the water flow, the underwater toy moves slowly while the underwater toy moves, so that the movement does not become simple.

According to the third aspect of the present invention, since the hole and the projecting piece are formed at one time, work efficiency is good.

According to the invention of claim 4, the motor is mounted in the sealed space of the toy main body, and is configured so that buoyancy is generated by the sealed space. And not.
