Title: The Innovative Mind of Shigemitsu Chigira
Introduction: Shigemitsu Chigira, a renowned inventor based in Tokyo, Japan, has made significant contributions to the field of mechanical engineering, particularly in the development of recoil starters. With a total of 5 patents to his name, Chigira's innovations reflect his dedication to enhancing the efficiency and functionality of starting mechanisms in various applications.
Latest Patents: Among Chigira's most notable patents are two designs for recoil starters. The first patent details a recoil starter that comprises a starter case with a reel support shaft and a ratchet guide. The ratchet guide is designed to be rotatably attached to the reel support shaft, ensuring a frictional resistance that optimizes performance. It features a through hole for the insertion of the reel support shaft and a locking portion that securely engages with the shaft's inner periphery, restricting the movement of the ratchet guide along the axial direction when locked.
The second patent further innovates on the recoil starter concept by including a reel support shaft, a rotatable rope reel, and a ratchet member. This configuration allows the ratchet member to swing on the rope reel while being restrained by a swing-prevention portion. The design ensures that when the rope reel rotates for engine starting, the guide portion effectively pushes the ratchet member outward, while also preventing unnecessary swinging when not in contact with the guide.
Career Highlights: Shigemitsu Chigira is currently affiliated with Starting Industrial Co., Ltd., a company that focuses on manufacturing starter mechanisms and related components. His work there has not only advanced the technology behind recoil starters but has also contributed to the company's reputation as a leader in this specialized market.
Collaborations: Throughout his career, Chigira has worked alongside notable colleagues such as Tetsuya Yamada and Tetsuya Kasamatsu. Their joint efforts have fostered a collaborative environment that encourages innovation and the exchange of ideas, resulting in the successful development of various cutting-edge technologies.
Conclusion: Shigemitsu Chigira's inventive spirit and technical expertise have positioned him as an influential figure in mechanical engineering. His patents, especially in the domain of recoil starters, not only illustrate his creativity but also showcase the practical applications of his work in enhancing the efficiency of engine start mechanisms. As he continues his journey at Starting Industrial Co., Ltd., there is no doubt that Chigira will remain a key player in the realm of innovations and inventions.
