Shigeo Oi is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of connector technology, holding a total of seven patents. His work reflects a deep understanding of mechanical design and functionality.

Latest Patents

Among his latest patents, Shigeo Oi has developed a connector that includes a connector body and a retainer. The connector body features a first opening and a second opening. The retainer consists of a first leg and a second leg. A second end part of the retainer is temporarily locked at a position that is separated from the first end part and is displaced in the insertion direction of a first pipe relative to a restriction position. This position restricts the detachment of the first pipe. When the first pipe is inserted into an insertion hole, the temporary locking of the second end part is released, allowing it to move to the restriction position due to a restoring force generated by the elastic deformation of the retainer. Another patent describes a connector that includes a connector body and a retainer, where the retainer is elastically deformable. This design allows for a widening distance between the first leg portion and the second leg portion when a force is applied in the insertion direction.
