DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block used as an assembling play equipment, and is not provided in a conventional block of this type.
The present invention relates to a block capable of assembling various shapes by joining a large number of blocks formed of triangular prisms.

2. Description of the Related Art Hitherto, there has been a playground equipment used for children's play and called an assembly block. This is a block that has a convex part on one side of the cube and a concave part on many sides. By using many such blocks, the irregularities of the blocks are continuously joined to form various shapes. It is something to prepare. However, since this block merely joins predetermined surfaces, it can be assembled into a substantially fixed shape but has little variability. To compensate for this, we have prepared various types of blocks, such as a cubic shape such as a plate, a rectangle, or a large or small block.However, the disadvantage that they can only be joined in one direction cannot be solved. The cost was high because of the need for

[0003]

In order to solve the problem of various sizes and shapes even when such a conventional block is a cube, one type of block having exactly the same size and shape is formed. However, there is a need to develop blocks capable of assembling various shapes by sequentially joining a large number of blocks that can be joined with the same size and shape.

[0004]

In the present invention, as a means for solving such a problem, there are provided a plurality of hollow triangular prisms having a plurality of concave holes penetrating therein and an outwardly projecting plurality of convex portions. Is a block in which the remaining two surfaces are each formed with only a plurality of concave holes that also penetrate inside, and the blocks have two concave holes and convex portions, or have a concave hole and convex portions. And an assembling play equipment block based on the fact that only the surface of the recess and the hole can be joined.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows each surface of the block 1 of this embodiment. A is a front view, B is a plan view, C is a right side view, D is a rear view, and E is a view showing a slope (hereinafter, a slope). In the description, these are referred to as A-plane, B-plane, C-plane, D-plane, and E-plane). The shape of the block 1 is a hollow triangular prism, and in this embodiment, a concave hole 2 penetrating inside is provided on two surfaces A and C, and three surfaces B, D, and E are similarly formed on the inside. The convex portions 3 are provided alternately with the concave holes 2 penetrating therethrough. As shown in FIG. 2, the arrangement of the concave holes 2 and the convex portions 3 formed on
The center of the convex part 3 or the concave hole 2 formed in the square or right isosceles triangle of each surface A, B, C, D, E of the (triangular prism) is the center of the circumcircle of the square of each surface of the triangular prism. It is set at the center of the same shape as the eight congruent isosceles triangles (intersections of the bisectors of each inner angle) divided by the symmetry axis of the book. Therefore, four concave holes 2 are formed on the surface A, and four concave holes 2 are formed on the surfaces B and E.
Four convex portions 3 are provided in the same manner as the two concave holes 2, eight concave portions 2 are provided on the C surface, and two convex portions 3 are provided on the D surface in the same manner as the two concave holes 2. The reason why only the concave hole 2 is provided without providing the convex portion 3 on the A surface and the C surface is that only the concave hole 2 is provided if the surface without the convex portion 3 is easier to assemble at the time of joining. However, the surface without the convex portion 3 is not limited to the A surface and the C surface, and may be provided on any surface. In addition, the concave portion 2 and the convex portion 3
Are arranged as described above, so as shown in FIG.
The two blocks 1 are joined together at the E side, and
When the pieces are joined to form a quadrangle, the central imaginary line F of the concave hole 2 and the convex portion 3 located at the center is the same as the central imaginary line G of the concave hole 2 and the convex portion 3 located on each surface of the block 1. Becomes FIG. 4 is a diagram for explaining the molding structure of the block 1 in the present embodiment, and illustrates a cross section taken along the line aa of the right side view C in FIG. 1. As shown in FIG. 4, at the time of molding, it is separated into a hollow triangular prism H without a bottom and a bottom plate I, and the bottom plate I is fitted to the bottom of the triangular prism H and fixed using an adhesive. Things. Although the present invention employs a triangular prism block, it may be a cube. In other words, it is equivalent to a cube having the E surfaces of the block 1 according to the present invention joined together to form a cube, and the positions of the concave holes 2 and the convex portions 3 are also the same. Therefore, two concave holes on three sides
And the convex portions 3 are alternately formed, and only the concave holes 2 are formed on the other three surfaces. In FIG. 1, a hollow state is not shown in order to avoid complicating the drawing,
FIGS. 2 and 3 are explanatory diagrams showing the arrangement of the concave holes and the convex portions, so that the convex portions protruding outward are not shown.

[0006]

As described above, according to the present invention, a plurality of hollow holes 2 penetrating inside and a plurality of convex portions 3 projecting outward are formed on any three surfaces of a hollow triangular prism, and the remaining two surfaces are formed on the remaining two surfaces. A block 1 in which only a plurality of concave holes 2 penetrating inside are formed.
And an assembly game based on the fact that the surfaces having the two concave holes 2 and the convex portions 3 or the surfaces having the concave holes 2 and the convex portions 3 and only the concave holes 2 can be joined together. Since it is a component block, this type of conventional block is a block having a convex portion on one side of the cube and a concave portion formed on multiple sides, and using a large number of such blocks, the unevenness between the blocks is continuously formed. By joining together, various shapes were prepared, but since this block simply joins the determined surface to surface, it is possible to assemble it into a nearly defined shape It was scarce. To compensate for this, we have prepared various types of blocks, such as plate-shaped cubes, rectangular squares, and large and small, but the disadvantage that they can only be joined in one direction can not be solved,
In addition, the cost is increased due to the necessity of various types of blocks. However, in the present invention, a concave hole 2 and a convex portion 3 are provided on each surface of one block 1 (for easy assembling and diversification). There is also a surface having only the concave hole 2), and the surfaces can be joined to each other.
Can be assembled into a variety of shapes by joining together. Moreover, the arrangement of the recesses 2 and the projections 3 formed on each surface is such that the center of the projections 3 or the recesses 2 formed on the respective surfaces A, B, C, D and E of the block 1 is Since it is set at the center of the same shape as the eight congruent isosceles triangles divided by the four symmetry axes through the center of the circumcircle of the square of the surface (the intersection of the bisectors of each inner angle), The joining range can be further expanded. In addition, since the block 1 is formed as a hollow triangular prism, the weight can be reduced, and further, the material cost is low, so that not only the cost can be reduced but also the handling becomes easy. In addition, since the recess 2 penetrates the inside, the forming process is easy, and there is no fear that dust is tolerated in the recess 2, which has various effects that are remarkably remarkable.
