Description

[Detailed description of the invention] This invention is an educational toy equipped with a hollow block body with a suction part.
Specifically, the present invention relates to an educational toy that includes a hollow block body with a suction part that displays numbers, letters, etc. on the front surface, has a suction part on the back surface, and is used by adhering the suction part to a flat board such as a blackboard.

Conventionally, a blackboard has been used as an educational toy for teaching young children the names of letters and objects.

For example, a set includes a block and a blackboard, characters, figures, etc. are displayed on the block attached with a magnet, and the block is used by attracting it to an iron blackboard.

However, in this case, it is necessary to attach a magnet or use an iron blackboard, which increases the cost and makes it heavy, making it inconvenient to carry.

It is an object of the present invention to solve the above-mentioned drawbacks and, in particular, to propose an educational toy comprising a hollow block body integrally constructed with a suction part.

That is, the present invention is characterized in that a suction portion having a suction edge is formed on at least one side of a hollow synthetic resin block body, and the block body having the above structure is suctioned to a planar suction plate.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Note that Fig. 1 is a front view of the block body according to the present invention, and Fig. 2 is a front view of the block body according to the present invention.
The figure is a rear view, and Figure 3 is a front view showing an example of a display board.
FIG. 4 is an explanatory cross-sectional view showing how the block body is used, and FIG. 5 is a cross-sectional view showing another manner in which the recessed portion is arranged.

In FIGS. 1 to 4, reference numeral 1 indicates a hollow block body.

A suction portion 2 is formed on one surface of the block body 1, and a recessed portion 3 is provided in the center of the other surface of the block body 1 to be recessed into the vicinity of the center of the suction portion 2.

The suction part 2 has a raised annular peripheral edge (suction edge) 2a on the surface of the block body 1, and has a concave surface formed inside the peripheral edge 2a, and is pressed onto a flat surface such as a blackboard. As a result, the inside becomes negative pressure and adsorption occurs.

The block body 1 integrally provided with the suction part 2 and the recessed part 3 having the above structure can be easily obtained by blow molding of synthetic resin.

Further, if the block body 1 can be constructed as a hollow body that integrates the suction part 2 and the recessed part 3 in this way, its shape is not limited to a circular shape at the front as shown in the figure, but for example, a triangular shape, It may be configured as a rectangle or the like.

With the above structure, the block body 1 is easily attracted to the suction plate 5 by pressing it against the suction plate 5 such as a blackboard as shown in FIG.

When pressing the block body 1 against the suction plate 5 in this way, the opposite side of the suction part of the block body 1 is pressed.
At this time, if there is no recessed part, the block body 1 is formed by integrally molding the suction part 2 and is therefore soft as a whole, and therefore, when force is applied, the block body 1 will be dented.

The suction portion 2 cannot suction properly unless the suction edge 2a contacts the blackboard 5 evenly.

Therefore, if excessive deformation occurs in a part of the block body 1, the suction edge 2a will not come into contact with the suction surface on average.
Adsorption conditions are also affected.

However, since the block body 1 is formed with a recessed part 3 that is recessed near the suction part from the surface opposite to the suction part 2, just by slightly pushing the surface opposite to the suction part 2, Since the tip of the recessed part 3 presses the center of the suction part 2 and the block body 1 does not deform much, the suction edge 2a contacts the plate 5 on average and can quickly spread outward. .

Note that since the block body 1 has a certain thickness, the concave portion 3 deforms considerably when pressed, and the recessed portion 3 is intended to suppress this deformation and effectively achieve suction. It is not necessary to provide it on the opposite side; for example, as shown in FIG. 5, the recessed part 3' can be formed so as to protrude inward from the center of the suction part 2.

A display board is attached to the surface of the block body 1 on the recessed portion 3 side.

This flexible display board 4 is made of paper, a synthetic resin board, or the like, on which characters or symbols to be taught, such as numbers, katakana, hiragana, and kanji, are displayed.

In this way, when the display board 4 is attached to the surface of the block body 1, since there is the recessed part 3 as described above, there is little deformation even when the block body 1 is pressed, so the display board 4 does not peel off. , will not be damaged.

In summary, the educational toy of the present invention is a hollow block made by blow-molding soft synthetic resin, and is provided with a suction part that can be well adsorbed through a recessed part. It is attracted to the surface to be attracted, is easy to handle, and is safe because it does not require metal parts such as magnets.

In addition, a display board that displays letters, numbers, symbols, etc. is attached to one side of the block, so children can learn letters, numbers, etc. while having fun adhering to the block, which has a high educational effect. can be obtained.

Furthermore, since the block body can be integrally molded by blow molding, it is much cheaper than conventional products.
