Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to toys.

[0002]

2. Description of the Related Art Conventionally, there is a toy having a connecting block, for example, a plastic toy having a convex portion and a concave portion as shown in FIG.

[0003]

However, this conventional technique has a problem in that if the material is hard, there is a risk of being injured when accidentally hitting it. There is a problem that it cannot be connected and that the connection cannot be made if the accuracy of the product is poor because the material is not flexible. Accordingly, an object of the present invention is to provide a connection block that is safe, flexible, and has a high degree of freedom in connection.

[0004]

The connecting block according to the first aspect of the present invention is characterized in that the connecting block is formed by forming a concave portion and a convex portion on a block made of an elastic material. A connecting block according to a second aspect is characterized in that the elastic material in the connecting block according to the first aspect is made of polyurethane foam or cellulose sponge. A connecting block according to a third aspect is characterized in that, in the connecting block according to the first or second aspect, the shape of the convex portion is increased at the tip.

[0005]

The connection and separation can be freely performed by fitting the concave portion of the block and the convex portion of the block having a shape fitted to the concave portion. In addition, the sponge contracts when connected, so that the sponge is easily connected. After the connection, the sponge in the convex portion in the concave portion is firmly connected to return to the original state, so that the sponge is hard to be detached.

[0006]

Embodiments of the present invention will be described below. The concave portion 2 is formed on three of the six surfaces of the rectangular parallelepiped main body 1 of the connecting block 4 shown in FIG. 1, and the convex portions 3 are similarly formed on the other three surfaces. As shown in FIG. 2, the shape of the projection 3 is such that the tip is larger than the rectangular parallelepiped body 1 side. Each of the rectangular parallelepiped main body 1 and the convex portion 3 is made of an elastic material and is integrally formed. In the structure as described above, when there are a plurality of such connecting blocks 4 and they are used, each connecting block 4 is connected with both hands so that the surface of the concave portion 2 and the surface of the convex portion 3 of the separate connecting block 4 are aligned. Block 4
And apply the force by matching the locations of the concave portion 2 and the convex portion 3. As shown in FIG. 2, the shape of the tip of the projection 3 is made larger than the shape of the recess 2, but the tip of the projection 3 is contracted by applying a force because it is made of an elastic material. The projection enters the inside of the gate 2 and the tip of the projection 3 tries to return to the original state inside the recess 2, so that it is difficult to come off, and the connection block is connected. Also at the time of separation, a force is applied so that the surface of the concave portion 2 and the surface of the convex portion 3 are separated from each other. As described above, connection and separation can be freely performed by temporarily applying a force and making use of the elasticity of the elastic material. For example, as an example of connection using two connection blocks 4, a connection between the short side and the short side as shown in FIG. 3A, and a connection between the long side and the long side as shown in FIG. , FIG.
FIG. 3D shows the connection between the short side and the long side as shown in FIG.
As shown in FIG. 6, there is a connection in which the long side and the long side are shifted by 90 degrees. By performing the connection as shown in FIG. 3 one after another by the plurality of connection blocks 4, various shapes can be created. An example of a form formed as a result of the connection is a giraffe as shown in FIG. Further, as shown in FIG. 5, since the connecting block 4 itself has flexibility, it can be deformed by applying a force to the connected aggregate while being connected.

The present invention is not limited to the above embodiment. For example, the shape of the rectangular parallelepiped main body is not limited to a rectangular parallelepiped, and may be any shape. Also, the shape of the convex and concave portions,
The position is also variously deformable. Further, it goes without saying that the convex portion may be formed even when adhered to the block as a separate body.

[0008]

As described above, conventionally, the connecting block toy made of a hard material is also made of a sponge (polyurethane foam).
By doing so, it is extremely safe because it has the ability to absorb shocks, and because the material itself is flexible, it can be deformed after assembling, and more molding possibilities are obtained. In the past, the only place to use was a daily play area, but by using a sponge, children can wash while playing in the bathroom, which attracts children who do not like bathing.
