Title: Takami Koyama: Innovator in Elevator Technology
Introduction
Takami Koyama is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of elevator technology, holding a total of 2 patents. His innovative designs have improved the functionality and efficiency of elevator systems.
Latest Patents
Koyama's latest patents include an elevator device and a roller guide assembly. The exemplary roller guide assembly for an elevator device comprises a shaft supporting a roller for engaging a guide rail, a shaft support member that receives the shaft, and a member inserted between the shaft and the shaft support member. This invention allows the shaft to be supported by the shaft support member via an elastic member. When the rollers are biased in the horizontal direction by the guide rail, the member limits the shaft from turning relative to the shaft support member. Additionally, the elevator car, which moves vertically along the hoistway, is equipped with a roller guide assembly guided by a guide rail. The roller guide assembly features a horizontal fixing shaft fixed to a base member and rollers supported by the horizontal fixing shaft. Each roller is designed with a roller outer circumference section, a rolling bearing, an annular rubber, and an inner cylinder. This configuration eliminates the need for a conventional spring or damper mechanism, as the rubber deforms elastically.
