Latest Patents

One of his latest patents is a pillar fixing metal fitting. This invention includes a joint base in a groove shape primarily composed of a joint metal. It features a cover spacer capable of supporting the pillar's axial load by covering the joint base. The joint base consists of a plane section in rectangular shape that coincides with the end surface of the pillar, along with a pair of groove walls bent vertically in an L shape. Additionally, the joining plate stands from the plane section and is supported by a welded part that contacts at least the pair of groove walls or groove bottom. The cover spacer also includes a plane section in rectangular shape for supporting the pillar by abutting the pillar's end surface, with a pair of groove walls composed of side edges of the plane section bent vertically in an L shape. A slit is drilled to allow the joining plate to fit into the slit when the cover spacer covers the joint base.

Another significant patent is a building and construction method that enhances workability without causing variations in the quality of buildings. This method allows for the easy joining of materials without special processing by forming mortises. The wooden building constructed by this method includes horizontal and vertical members, such as lower frames, first upper frames, second upper frames, and side joists as horizontal members, along with pillars as vertical members. The lower, first upper, and second upper frames, and side joists include mortises in the longitudinal direction. The first upper frames feature an entire length recessed groove, while the second upper frames include an entire length protrusion. The mortises at the lower frames and the first upper frames are through holes, and the pillars have protrusions at both ends that fit into the mortises.
