Description

[Detailed description of the invention] This invention relates to an educational toy that allows the user to learn the relationship between two patterns by comparing them.

In conventional toys of this kind, two designs are provided on both sides of the toy, separated from each other, and both designs are always displayed. Therefore, since infants only passively look at the two patterns that are already displayed and do not act on their own, their association and memory efforts when recognizing the two patterns are very weak, and the educational effect is low. It was hot. There is some time between looking at the first pattern displayed on one side and turning the pattern support over to see the other side, but there is a second pattern already displayed on the other side. Therefore, the user could simply wait for the displayed pattern to be seen without requiring any effort, guesswork, or memory.

In view of the above points, the purpose of this invention is to provide an educational toy that requires the infant using the toy to make an effort to draw out memories on his or her own, and which can dramatically improve the educational effect.

Next, this invention will be explained based on the drawings.

In this invention, a palm-sized main body, that is, a flat main body a of a size that can be covered on one side with the palm or a size that can be held in the palm is used. Any material such as paper, plastic, wood, or metal can be used, but it is preferable to use a material with good thermal conductivity or a thickness that allows heat to pass through. One side is provided with a first pattern b using ordinary pigments, that is, unchangeable pigments, and the other side is provided with a first pattern b.
A second coloring using a thermochromic dye or this and a general pigment.
A pattern c is formed.

When this thermochromic dye is used alone to form the second pattern, if the surface of the main body is colorless at room temperature, the color is either erased and the pattern cannot be seen, or the color is the same as the surface color of the main body. It is difficult to tell whether there is a pattern, but when the temperature reaches the same level as a person's body temperature, it develops a color or changes to a color different from the surface color of the main body.

The second pattern may be formed from a general pigment, and a thermochromic pigment layer may be formed on the top surface of the second pattern. Ru.

Further, the second symbol has a semantic relationship with the first symbol. For example, if the first pattern is a number, the second pattern is a picture of the number corresponding to the meaning of the number, or if the first pattern is hiragana or katakana, the kana is A picture of an object whose name appears at the beginning of a word is considered a secondary pattern. Alternatively, the second pattern may be a picture of an object that is used in close contact with the object represented by the first pattern. Furthermore, one of the two languages (for example, Japanese) may be used as the first symbol, and the other (for example, English) may be used as the second symbol.

In FIG. 1, d and e are protective materials such as transparent films or sheets.

With the above configuration, while the toy is not held in the palm of the hand or pressed against the body, the first pattern made of general pigment is displayed only on one side of the toy, and nothing is displayed on the other side. Therefore, the user:
By looking at the first pattern, it is possible to think about what the pattern formed on the opposite side is. That is, since the user tries to use their thinking, reasoning, or memory skills, it is expected that these will be improved.

After trying to answer the question, if you hold the toy in your palm or press it against your body to warm it up,
When the temperature reaches the same level as body temperature, the temperature-sensitive color-changing pigment disappears, develops color, or changes color, and the second pattern appears on the other side, so the user can touch the first pattern. You can easily check whether your answers are correct or not. Then, when the body is released from the toy and the temperature returns to normal temperature, the second
The pattern disappears again, so it can be used repeatedly for educational purposes. In addition, the second pattern can easily appear or disappear by simply holding it in the palm of the hand, allowing the user to enjoy learning and education while enjoying the changes.

FIG. 2 shows an example of how it is used, where A is an example of the first symbol and B is an example of the exposed second symbol.

As described above, according to this invention, the user can actively improve his or her thinking, reasoning, or memory skills while enjoying the changes in the patterns.
