Title: Yuichi Shibata: Innovator in Coil Spring Technology

Introduction

Yuichi Shibata is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of coil spring technology, holding a total of 2 patents. His innovative designs have enhanced the functionality and efficiency of coil spring devices.

Latest Patents

Shibata's latest patents include a coil spring device that features a main body spring and an insulator. The insulator is designed with a support groove that extends around a coil axis, into which the lower end portion of the main body spring is fitted. This design ensures that the lower end adheres to the inner surface of the support groove. The inner surface is equipped with multiple spacer protrusions that support the outer peripheral surface of a wire rod. Notably, the inclination angles of the side wall surfaces of adjacent spacer protrusions differ from each other, enhancing the device's performance.

Another patent describes a coil spring that also includes a main body spring and an insulator. In this design, the support groove extends in an angle range of 180° or more and 360° or less around the coil axis. The volume of the spacer protrusions occupying the gap between the inner surface of the support groove and the outer peripheral surface of the wire rod is larger at the center portion than at other areas, optimizing the spring's functionality.
