Title: Hiroyuki Hirose: Innovator in Trigger Switch Technology

Introduction

Hiroyuki Hirose is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of power tools through his innovative designs. With a total of 6 patents, Hirose has established himself as a key figure in the development of trigger switch technology.

Latest Patents

Hirose's latest patents include a sophisticated trigger switch for power tools. This trigger switch features a case with a switching mechanism inside, which is open on one side. A cover is designed to fit inside the case's opening, effectively closing it. The trigger is positioned outside the case and operates the switching mechanism through a sliding action via a plunger. An engaging depression is formed on the inner wall surface of the case's opening edge, while a shoulder is created on the outer peripheral end of the cover. An engaging projection extends outward from the shoulder's side surface, allowing it to engage with the corresponding depression. Additionally, a joint groove is formed by the inner wall surface and the shoulder, which is filled with an adhesive agent.

Another patent disclosed by Hirose involves a trigger switch that includes fixed contacts forming main contacts in series. This switch functions to supply power to a motor and features slide plate parts connected to the fixed contacts. Movable contacts are provided in an actuator that interlocks with an operation part, along with auxiliary contacts that slide on the slide plate parts. When the operation part is drawn, the actuator moves forward, causing the movable contact to make electric contact with the fixed contact, thereby supplying power to the motor. Simultaneously, the auxiliary contact bridges over the slide plate parts to ensure no potential exists between the movable and fixed contacts. Releasing the operation part results in the movable contact separating from the fixed contact, while the auxiliary contact continues to bridge over the slide plate parts.
