3D puzzle

Abstract

Provide a three-dimensional puzzle. [Solution] If part 23 is a piece obtained by removing one corner of a cube with a side equal to the height from a board with a height-length-width ratio of 1:2:3, and part 223 is a piece obtained by removing two corners of a cube with a side equal to the height from a board with a height-length-width ratio of 1:3:3, this three-dimensional puzzle is made up of four parts 23 and one part 223, and can be used to build a cube with a side three times longer than the above cube. This increases the selection of safe toys that can be enjoyed by people of all ages, from young children to the elderly.

Description

[Technical Field]

[0001] This relates to a toy that allows a specific three-dimensional shape to be constructed by combining multiple parts. [Background technology]

[0002] There are toys on the market that allow you to build a large cube by combining multiple parts, such as a toy that allows you to build a large cube from one type of L-shaped part, but there are no toys that allow you to build a large cube from two types of L-shaped parts.

[0004] Increase the selection of safe toys that can be used by everyone from young children to the elderly. [Means for solving the problem]

[0005] If part 23 is a piece obtained by removing one corner of a cube with a side equal to the height from a board with a height, length, and width ratio of 1:2:3, and part 223 is a piece obtained by removing two corners of a board with a height, length, and width ratio of 1:3:3 from one corner of a cube with a side equal to the height, then this is a three-dimensional puzzle consisting of four parts 23 and one part 223, from which a cube with a side three times longer than the cube above can be constructed. [Effects of the Invention]

[0006] The use of the toy of this invention can contribute to the development of intelligence in young children and the maintenance of cognitive function in the elderly. [Brief explanation of the drawings]

[0007] [Figure 1] 1 is a perspective view showing how a cube can be made by combining four parts 23 and one part 223 of the present invention so that the black circles are in contact with each other. [Figure 2] 1 is a perspective view showing that two parts of a cube made of four parts 23 and one part 223 of the present invention can be interchanged. DETAILED DESCRIPTION OF THE INVENTION

[0008] The 3D puzzle of this invention can be made from cypress wood, but the material is not limited to cypress. To prevent injury, the corners and edges are rounded. Another way to play is to observe the surface of the large cube and find the combinations of interchangeable parts. [Example]

[0009] The three-dimensional puzzle of this invention was made by cutting out four pieces 23, each sandwiched between six sides measuring 4cm, 2cm, 2cm, 2cm, 6cm, and 4cm, and one piece 223, each sandwiched between six sides measuring 2cm, 2cm, 4cm, 4cm, 6cm, and 6cm, from a 2cm thick cypress board. It was confirmed that these pieces could be combined to form a cube, and that at least one set of pieces could be interchanged. [Industrial Applicability]

[0010] The three-dimensional puzzle of this invention is expected to be in demand in homes and elderly care facilities, targeting people of all ages, from young children to the elderly.

Claims

[Claim 1] When a piece obtained by removing one cube from a corner of a board with a height, length, and width ratio of 1:2:3 and having a side equal to the height thereof is called piece 23, and a piece obtained by removing two cubes from one corner of a board with a height, length, and width ratio of 1:3:3 and having a side equal to the height thereof is called piece 223, this three-dimensional puzzle is made up of four pieces 23 and one piece 223, and can be used to construct a cube with a side three times longer than the cube described above.
