Title: Innovations of Yoshihisa Kohzu
Introduction
Yoshihisa Kohzu is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of engineering, particularly in the design of working machines. With a total of 2 patents, his inventions reflect a commitment to enhancing functionality and safety in machinery.
Latest Patents
Kohzu's latest patents include a counterweight device for arranging accumulators inside the counterweight of a working machine. This innovative device allows for the connection of an accumulator to the piping at the machine body side, enabling the movement of the machine body or work device even when the counterweight is not attached. The design features a counterweight fixed to a mount base at the rear end of a swinging frame, with an accumulator installed inside the counterweight using a temporary placing support structure. This structure can be temporarily placed and attached to the end plate at the swinging frame side before the counterweight is secured.
Another significant invention by Kohzu is a non-slip structure that efficiently prevents slipping without complications caused by a through hole. This non-slip structure is characterized by a portion of a metal plate, such as a steel plate, being sheared to form cutting lines. The protruded piece is then pulled up along these cutting lines to a height that does not exceed the thickness of the steel plate, ensuring that the sheared surface does not create gaps or through holes when in contact with the steel plate.
