Abstract

(57) [Summary] (Corrected) [Purpose] A scientific toy that uses a ferrite magnet ring as a theme of aesthetics and interest that anyone can be interested in. [Configuration] Rectangular rotating frame 4 with four impellers 3 attached
And the bearing 10, frame 11 and frame that support this
A handle 6 that rotates once is provided. A ferrite magnet 12 or the like, which functions as a magnet stopper, is installed in the lower center of the gantry 11 in order to stabilize the wobbling when the rotating frame 4 is upright. If the frame is set upright, the impellers will rotate together and fall. After dropping, if you rotate the frame 180 degrees, this time you will see the back surface of the blade and fall.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a scientific toy that can be used internationally and is constructed with the theme of aesthetics and interests in order to make a toy that anyone can be interested in using a ferrite magnet ring.

[0002]

[Prior art]

 I understand only the fact that if you put a ferrite magnet ring through a wire and stand it vertically, the ring will drop while rotating, and it seems that a few blades were attached to this ring in parallel and it was commercialized at all. not.

[0003]

[Problems to be solved by the device]

 In order to make a new scientific toy based on the facts described above, we used four magnet rings and attached them with different numbers of blades of one, two, three and four and rotating them. And when the four impellers have fallen downward, turn the rotating frame 180 degrees and show it as the back side again and collect it as one toy. I did.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a rectangular rotating frame with four wires attached through an impeller in parallel, a bearing for supporting this, a frame and a rotating frame are designed to be able to rotate 180 degrees, and there is no fluctuation at the time of conversion. It is composed of a magnetic stopper to prevent it.

In the plan view of the impeller of FIG. 4, one to four blades of different shapes are made from four different ring magnets on each of the 1 ring magnet and attached to the ring magnet with an adhesive. Make a clean impeller by using a pattern of colored origami paper, gold paper or silver paper on the front and back of the blade.

The rotating frame has a rectangular shape, the vertical frame has a rectangular cross section, and the horizontal frame has an L-shaped cross section. Four wires are arranged in parallel in the vertical direction, a ring magnet is passed through the wire, and then a fixed collar is used. Fixed to the horizontal frame. A handle with a hole for the index finger is attached to one outside of the horizontal frame, and it is used when rotating 180 degrees. A short shaft is attached to the center of the left and right vertical frames, and it is held by the left and right bearings with this as the axis of rotation.

Four round seats are attached to each of the upper and lower roots of the wire, passing through the wire. This prevents the inconvenience that one or more blade cuts bite into the edge of the horizontal frame and become difficult to fall downward when turning 180 degrees when the impeller falls diagonally.

A thin lead plate with a width of about 1 cm or a substitute is wrapped around the inner part where the wire penetrates through the round seat and is exposed. This will reduce the magnetic force of the ring magnet and make it easier for the impeller to start falling.

The pedestal has a structure that can hold bearings on each of the upright columns on the left and right, and has an appropriate weight so that it will not fluctuate when switching the rotating frame.

[0010] If you release the hand when the rotating frame is set upright, the frame becomes unstable and lacks stability. Therefore, install a ferrite magnet in the lower center of the frame, and attach it to the outer side of the upper and lower horizontal frames. It acts as a magnet stopper to stabilize the rotating frame.

[0011]

[Effect of device]

 Because the blades of different shapes are attached to the four ring magnets, it looks like falling while rotating to the right or left. One blade is like UFO, and two or more blades are like a butterfly. Moreover, the wings with gold or silver paper reflected on it are glittering, making it a toy that children and adults can be interested in. In addition, you can easily rotate 180 degrees so you can enjoy the rotation of the impeller as many times as you like. It is a toy that is easy to operate, has excellent safety, is robust, and is resistant to failure.
