Abstract

<P>PROBLEM TO BE SOLVED: To provide a building block type combination block for people of all ages from children to adults to the elderly, combining and piling up right triangular pyramids (regular tetrahedrons) and square pyramids of optional sizes for molding by using a suitable number of only two kinds of solids: right triangular pyramids (regular tetrahedrons) and square pyramids, and besides enabling various molding, although most of the conventional building block type combination blocks are mainly for infants and children as a toy. <P>SOLUTION: The shapes of faces constituting solids of right triangular pyramids (regular tetrahedrons) and square pyramids having the same side length 1 are all equilateral triangles except the base of the square pyramid, and when the solids are combined, the faces of the equilateral triangles are matched to generate continuity, thereby molding various combinations. A suitable number of solids are combined to optionally mold right triangular pyramids (regular tetrahedrons) and square pyramids having an integer multiple of one side length 1 and besides freely mold its similar form and continuous form. Thus, the children to adults and persons of advanced age are allowed to enjoy the process of its creation, and have joy by a sense of achievement to complete a unique molding. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention is a building block that can form various shapes by combining an appropriate number of two types of solids having the same side length l, a regular triangular pyramid (regular tetrahedron) and a regular square pyramid.

  Conventionally, a building block called a general building block is a combination of a plurality of solid shapes of various types to form an unlimited shape (for example, see Patent Document 1) and a plurality of types of specific shapes. There is a block-type assembly block in which an appropriate number of three-dimensional pieces are combined and stacked to form a specific shape (see Patent Document 2).

Japanese Patent Laid-Open No. 9-155072 Published Utility Model Gazette (U) Hei 4-42898

  The blocks that are stacked and combined using multiple solid shapes of various types can be shaped in various ways depending on the combination, but the main purpose is to demonstrate the free imagination of infants, while the special shape The building block type block using a plurality of types of solids is to enjoy a sense of accomplishment obtained by assembling into a specific shape.

  In the present invention, a proper triangular pyramid or pyramidal quadrangular pyramid can be obtained in a desired size by using only a few simple solids of a regular triangular pyramid (regular tetrahedron) and a regular tetragonal pyramid having the same side length l. The purpose is to provide a combination block that can be enjoyed widely from children to the elderly, in addition to being piled up in combination, and enabling various forms such as similar shapes and continuous shapes.

  The invention according to claim 1 is obtained by combining and accumulating two kinds of proper three-dimensional pyramids having a regular triangular pyramid (regular tetrahedron) having the same side length l and a regular square pyramid having the same side length l. In addition to being able to form a regular triangular pyramid (regular tetrahedron) or a regular quadrangular pyramid that is an integral multiple of l, various shapes can be formed.

  In the assembled block according to claim 2, in the assembled block according to claim 1, in order to maintain a stable state in a shape in which each solid is combined and stacked, the vertical stress generated at the time of stacking on all surfaces where each solid is in contact with each other. It has friction resistance or adhesive strength to resist.

  As described above, the present invention combines two types of simple solids, that is, an equilateral triangular pyramid (regular tetrahedron) having the same side length l and an appropriate number of regular tetragonal pyramids, thereby obtaining an integral multiple of l. We provide various modeling objects such as regular triangular pyramid (regular tetrahedron), regular tetragonal pyramid (pyramid type), and similar and continuous types.

  In addition, children, adults, and elderly people can enjoy the process of creating such various shaped objects, and the act of creating and completing unique shaped objects is also effective for brain training and activation.

  The assembled objects can also be appreciated and enjoyed as decorations.

The perspective view which shows the assembly structure of the regular triangular pyramid (regular tetrahedron) and the regular tetragonal pyramid of side length 2l by the assembled block which consists of the regular triangular pyramid (regular tetrahedron) 1 and the regular tetragonal pyramid 2 which have the same side length l. A perspective view showing a configuration of a regular triangular pyramid having a side length of 3 l The perspective view which shows the assembly structure of the regular square pyramid of side length 3l The perspective view which shows the various modeling examples using the solid of this invention

BEST MODE FOR CARRYING OUT THE INVENTION

    The embodiment of the present invention is an equilateral triangular pyramid (regular tetrahedron) having the same side length l shown in 1 of FIG. 1 and a regular quadrangular pyramid having the same side length l shown in 2, and each surface constituting each is appropriate. Align the appropriate number of solids that have the friction resistance.

1 Regular triangular pyramid (regular tetrahedron)
2 Regular square pyramid l Standard length (side length) of one side

Claims (2)

  Two types of solids, the regular triangle pyramid (regular tetrahedron) and regular quadrangular pyramid with the same side length l, are all regular triangles except for the bottom of the regular quadrangular pyramid, so the faces and faces that make up each solid are Continuity is created by matching with each other, and a variety of combined molding is possible. By combining an appropriate number of elements, an equilateral triangular pyramid (regular tetrahedron) or regular quadrangular pyramid that is an integral multiple of the side length can be arbitrarily set. Block-type building blocks that can be combined in size, stacked and shaped, as well as various similar shapes and continuous types.   When three-dimensional objects are combined and stacked, vertical stress acts between the surfaces that are in contact with each other, and if the three-dimensional surfaces are smooth, the surfaces become displaced and become unstable. Therefore, each of the three-dimensional finished surfaces has a moderate frictional resistance or adhesive force, so that the displacement between the contact surfaces can be suppressed and a stable state can be maintained. .
