Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an underwater toy that moves underwater.

[0002]

[Prior art]

 Generally, a battery is often used as a power source of a toy. This is because batteries do not require cables or the like, and are easy to replace. However, in underwater toys that swim or operate in water, the batteries must be sealed in water because they are used in water. Similarly, when batteries are used, the power is greater than that of solar panels, so a means for deceleration is required, the movement is mechanical, and the motor and reduction gear connected to the batteries are waterproofed. Need.

[0003] However, the propulsion screws and wheels need to come into contact with water and the water bottom. Therefore, if the output shaft operatively connected to the motor and the drive shaft of the screw or wheel are made coaxial, the common shaft must be sealed with a waterproof seal in the middle.

[0004]

[Problems to be solved by the invention]

 However, in order to waterproofly seal the middle of the shaft, it is necessary to form a bulkhead in the middle of the shaft, penetrate the shaft through the shaft hole formed in the bulkhead, and seal between the shaft hole and the shaft. As for the method, this is technically very difficult.

An object of the present invention is to solve the above problems and to provide a motor and an underwater toy capable of completely waterproofing an output shaft and a drive shaft thereof with a simple structure.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the underwater toy according to the present invention has the following requirements. (B) The toy body has a shrimp shape. (B) The motor and the output shaft operatively connected to the motor are housed and arranged in a sealed container inside the toy body. C) A first magnet is fixed to an end of the output shaft, and the first magnet is disposed near a side wall of the container. (D) The first magnet is provided outside the container. The second magnet is rotatably disposed at a position opposed to the side wall with respect to the above (E) A driving means is connected to the second magnet (F) The driving means is a toy body (A) The power source of the motor is a solar panel.

[0007]

[Embodiment of the invention]

 FIG. 1 is a perspective view of an underwater toy simulating the shape of a shrimp. In FIG. 1, a solar panel serving as a power source is shown. And is arranged to receive light from above. The underwater toy is adjusted so as to sink to the bottom of the water.

As shown in detail in FIG. 2, a motor 4 and a reduction gear 5 (crown gear 5 a and spur gear 5 b) are arranged at the center of the toy body 3, and an output shaft 6 has an N pole and an S pole. A doughnut-shaped first magnet 7a on the same surface is fixed, and these are hermetically housed in a waterproof container 8 which is a continuous one.

On the other hand, a doughnut-shaped second magnet 7b is disposed opposite to the first magnet 7a with a partition 9 which is one side wall of the container 8 interposed therebetween. Is fixed. The rotation of the small pulley 30 is transmitted to the large pulley 32 through the rubber belt 31 at a reduced speed. The large pulley 32 is fixed to a drive shaft 33, and two linear members 34 having elasticity are attached to both ends of the drive shaft 33 at positions shifted from each other by 180 degrees. A transparent ball 35 is attached to the tip of each linear member 34.

According to the above configuration, when any surface of the solar panel 1 receives sunlight or illumination light, electric power is generated, the motor 4 rotates, and at the same time, the output shaft 6 and the first magnet 7a rotate. When the first magnet 7a rotates, the magnetic field changes, so that the second magnet 7b rotates in synchronism with this, and its rotational force is transmitted from the small pulley to the large pulley 32, and the drive shaft means 10 rotates. I do. Since the two linear members 34 operate alternately to kick the bottom of the water, the shrimp-type underwater toy operates to intermittently jump.

The feet are made of a thin film of rubber, and swing so as to follow the vibration of the toy main body 3 and changes in the water flow.

As described above, the motor 4 sealed in the container 8, the output shaft operatively connected to the motor 4, and the first magnet 7 a fixed to the output shaft drive the second magnet 7 b outside the container 8. Since the shaft can be rotated, it can be operated in water without being affected by water.

Further, the shrimp-type underwater toy operates underwater using electric power generated by the solar panel 1 as a power source. The electric power of the solar panel 1 is obtained by irradiating a light source for illumination or light from the sun, and there is no need to replace it like a battery, which is convenient. In addition, since the power obtained from the solar panel 1 is smaller than that of the battery, the rotation of the linear member 34 is also slow, resulting in a biological movement.

[0014]

[Effect of the invention]

 According to the invention of claim 1, the second magnet and the drive shaft outside the container are connected by the motor sealed in the container, the output shaft operatively connected to the motor, and the first magnet fixed to the output shaft. Because it can be rotated, it can be operated in water without being affected by water. Therefore, the shrimp-type underwater toy can be operated so as to jump by the linear material.

Further, since the power source of the motor is a solar panel, the underwater toy operates underwater by using the power generated by the solar panel as a power source. The power of the solar panel is obtained by irradiating light from the light source for the lighting and the sun.It is not necessary to replace it like a battery, so it is convenient and uses the energy of light, which is supplied inexhaustibly. Therefore, it can be used semi-permanently. Moreover, since the energy is not so large, it is suitable for expressing slow biological movement.
