AI Technical Summary
Existing building blocks lack a mechanism to connect block surfaces other than through direct perpendicular contact, limiting design flexibility and connection strength.
A dihedral shape with isosceles triangles connected vertically at their bases and symmetrical holes or recesses allows for parallel connection via diagonal sliding, enabling all sides of tetrahedral blocks to be connected simultaneously.
Enables flexible and robust connections between blocks, allowing designs to be easily modified and maintained without reassembly.

Abstract
Description
[Technical field]
[0001] The present invention is Product Wooden Block , and block set This is regarding. [Background technology]
[0002] Among building block toys, building blocks with interlocking parts allow the maker to create a work of appropriate strength in the shape intended by the maker. They have the advantage of being easy to assemble and disassemble repeatedly, and can be enjoyed according to the maker's creativity, so they are actually used by people of all ages. For practical building blocks, the manufacturer provides pictures or photographs of sample works, and a set is provided with the basic blocks and the accessory blocks necessary to create the presented works, and the work can be completed by connecting these building blocks in the right order. Also, works that are different in shape from the sample can be sufficiently practical if the maker designs them in advance.
[0003] However, practical building blocks have the disadvantage that the block faces that do not have a connecting mechanism and the block faces that have a connecting mechanism only have either a hole or a concave or convex function, so they cannot be connected depending on the combination of contact surfaces.
[0004] This drawback is a major obstacle when it comes to making shapes with blocks, as it makes it difficult to change the design on a whim or inspiration, and can lead to insufficient strength in the connections. Specifically, the surfaces of these practical building blocks are either a hole or a concave block face, a convex block face, or a flat surface, and they can only be connected in combinations of a hole or a concave block face and a convex block face. Furthermore, there is a problem that two or more blocks cannot be connected unless the connecting block faces face each other directly and can move perpendicularly to the connecting surface.
[0005] As an improvement, a two-sided shape is made by connecting two isosceles triangles with a ratio of three sides of 2:√3:√3 perpendicularly at the base, and a mechanism is provided on each of the faces with holes or concave and convex parts at symmetrical positions on the axis of symmetry. This mechanism of connection allows the two faces to be connected even when they cannot face each other directly, by sliding the moving direction at a 45° angle while keeping the faces parallel to each other, and allows two faces to be connected simultaneously on the horizontal and vertical planes. Then, a two-sided block is made by providing a reinforcing plate to maintain the shape and a mechanism to combine it into a tetrahedral block, and two two-sided blocks are combined to make a tetrahedral block. Another method is to cut off the four vertices of a two-sided block to make a square-cut two-sided block, and then combine two square-cut two-sided blocks to make a square-cut tetrahedral block. The method for actually making tetrahedral blocks and square-cut tetrahedral blocks using cardboard and wooden round bars is to cut each part, glue them together with adhesive to make a two-sided block, and then combine two of these to make a tetrahedral block. The method for making them using injection molding of synthetic resin thermoplastic resin is to make an injection mold for a two-sided block, make a two-sided block with a single injection from an injection molding machine, and then combine two of these to make a tetrahedral block. Figure 1 shows the appearance of a tetrahedral block made from cardboard. Figure 2 shows the appearance of a two-sided block made from cardboard. Figure 3 is an explanatory diagram showing how to connect tetrahedral blocks made from cardboard.

[0007] [Non-Patent Document 1] Written by Akira Toyama / Mathematics Square Volume 4 The Three-Dimensional World Japan Library Center Co., Ltd. Summary of the Invention [Problem to be solved by the invention]
[0008] The problem to be solved is that two or more blocks cannot be connected by combinations of contacting block faces with each other in practical building blocks. [Means for solving the problem]
[0009] The main feature of the present invention is that by providing a mechanism for simultaneously connecting two of the four faces of a tetrahedral block or a cut-corner tetrahedral block, contacting block faces between two or more tetrahedral blocks or cut-corner tetrahedral blocks are always connected to each other. Effect of the Invention
[0010] The tetrahedral blocks and corner-cut tetrahedral blocks of the present invention can be connected in sequence one by one up to four times using the bases of the isosceles triangles and corner-cut isosceles triangles as axes, and conversely, they can be removed one by one, so there is an advantage that even if you suddenly change your mind about a design or inspiration, there is little need to reconnect the blocks and you can continue creating the model as is.
