Latest Patents
Koketsu's latest patents include a unique through anchor and a method for manufacturing the same. In his design for a seat belt device, the through anchor features a groove that provides a boundary between a molded part and a resin piece. This design ensures that the boundary remains inconspicuous. Additionally, a projection part of a mold is strategically placed between the synthetic resin materials during the molding process. This prevents the heat from the molten synthetic resin material from directly affecting the resin piece on the surface of the through anchor.
Another significant aspect of his through anchor invention is its ability to disperse residual stress caused by thermal contraction, thereby reducing the risk of crack formation in the resin molding portion. The through anchor consists of a metal plate covered by a resin molding portion. Notably, a notch portion is formed in regions near the boundary, exposing part of the metal plate to the environment. This design allows for better thermal contraction management, minimizing the risk of cracks in the resin molding portion.
