Introduction

Yasuo Sekikawa is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of aviation technology, particularly in the design of cockpit doors for aircraft. With a total of 3 patents to his name, Sekikawa's work focuses on enhancing safety and functionality in aircraft design.

Latest Patents

One of his latest patents is a latch device for the cockpit door of an aircraft. This innovative latch device is designed to detect pressure reduction in the cockpit and release a bolt and stopper device to prevent the cockpit door from unexpectedly opening due to impact. The main latch device features a frame fixed to the door panel, with a latch base that can pivot around a pin. A bolt is inserted into a catch in conjunction with a door handle, while a holding/releasing portion secures the latch base. When a pressure difference occurs between the cockpit and cabin, a pressure-sensing piston activates, rotating a trigger and flapper to release the latch base. Additionally, a stopper device regulates the movement of the trigger in response to impact forces.

Another significant patent involves the design of the cockpit door itself. This cockpit door includes a hinge on one surface and a latch device on the other side, operable only from the cockpit. The door panel is reinforced with multiple layers of sheets bonded with thermoplastic adhesives, incorporating aromatic polyamide fiber and a honeycomb panel. A titanium alloy reinforcement plate is used to cover the gap between the door body and flap, ensuring structural integrity.
