Title: Shigenobu Sugasawa: Innovator in Chain Technology
Introduction
Shigenobu Sugasawa is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of chain technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest inventions is a chain and chain guide plate designed to suppress noise during chain traveling while also achieving cost reduction and space saving. This chain includes first plate rows and second plate rows, with each first plate row featuring a guide plate that has a guide slide contact section. This section comes into slide contact with an inner side guide and extends asymmetrically relative to an imaginary center line. The design ensures that lines drawn by the guide slide contact sections of multiple guide plates remain continuous in the chain's longitudinal direction.
Another significant patent is the ratchet type tensioner. This device features a toothed rack on its plunger and a pawl that cooperates with the rack. A recess is strategically placed between the front end of the rack and the protruding end of the plunger. In the initial stages of operation, the pawl can enter the recess, allowing the plunger to protrude and retract freely within a limited range. As the chain controlled by the tensioner elongates, the pawl engages with the rack to limit the plunger's retraction.
