Ultimate functional beauty of kumiki, improved joint details by the combination of kumiki

This kumiki is a combination of Ari and Koshikake, which will be secured once fitted together. In this example, Mechigai is also used in combination. When a tensile force is applied, Ari’s dovetail part causes a force to push the groove part, but the combined use of Mechigai prevents from strength to decrease by cracking. Mechigai also serves as a guide for easier assembly, with increased resistance against misalignment caused by bending of parts.
