Patent number: 10233054Abstract: An elevator car upper handrail apparatus, in which a connecting body is provided between respective ends of first and second side handrails on a landing side. The connecting body includes an opening/closing member which is rotatable between a closed position, in which a path for movement of a worker from a landing to a car upper surface is closed by the opening/closing member, and an open position, in which the path for movement is opened by the opening/closing member. The opening/closing member is configured to return automatically to the closed position. When the opening/closing member is in the closed position, the connecting body transmits an external force applied to one of the first and second side handrails in the width direction of a car to the other of the first and second side handrails.Type: GrantFiled: July 23, 2015Date of Patent: March 19, 2019Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Takahide Ishiguro, Naoyuki Maruyama, Hironobu Kamada, Hideki Miyahara, Kazuya Shindo

Patent number: 9751538Abstract: Provided is a sound absorbing panel that can satisfy the heat resistance properties and melting/dripping resistance properties required inside of a railway vehicle. A pier sound absorbing panel includes five sheets of first through fifth glass cloths that are stacked on an aluminum base plate. The edge section of the fifth glass cloth is affixed to the rear surface of the base plate using an adhesive, and the first through fourth glass cloths are fastened using staples. In other words, the first glass cloth and the base plate are fixed using an adhesive, and this adhesive is prevented from melting by the five sheets of the first through fifth glass cloths. The adhesive that fixes the edge section of the fifth glass cloth at the other surface of the base plate is prevented from melting by the five sheets of the first through fifth glass cloths and the base plate.Type: GrantFiled: October 31, 2013Date of Patent: September 5, 2017Assignees: CENTRAL JAPAN RAILWAY COMPANY, NIPPON SHARYO, LTD.Inventors: Yukio Takahashi, Hiroki Tsunoda, Yuya Futamura, Koichi Hayashi, Naoya Ozawa, Masaki Hase, Naoyuki Maruyama

Patent number: 9617119Abstract: In an elevator apparatus, a hoisting machine includes a driving sheave, and a motor portion that rotates the driving sheave, and is disposed in an upper portion inside a hoistway. A suspending unit is wound sequentially around a first car suspending sheave, a second car suspending sheave, the driving sheave, and a counterweight suspending sheave. The second car suspending sheave, the driving sheave, and the counterweight suspending sheave are disposed on a first side of a car guide rail center line that connects first and second car guide rails when viewed from directly above. A portion of the motor portion is disposed between a back surface of the second car guide rail and a hoistway wall. The driving sheave is disposed so as to overlap with the second car guide rail when viewed from a landing side.Type: GrantFiled: December 7, 2011Date of Patent: April 11, 2017Assignee: MITSUBISHI ELECTRIC CORPORATIONInventor: Naoyuki Maruyama

Publication number: 20130001020Abstract: In a safety system for an elevator, slip detection means detects a slip between a drive sheave and a main rope. A safety gear is mounted to a car, the safety gear being electrically operated by an actuator to cause the car to make an emergency stop regardless of whether a running direction of the car is upward or downward. A safety gear controller cuts power supply to a hoisting machine motor and causes the safety gear to make a braking operation upon detection of the slip between the drive sheave and the main rope by the slip detection means.Type: ApplicationFiled: September 11, 2012Publication date: January 3, 2013Applicant: Mitsubishi Electric CorporationInventors: Hiroshi Kigawa, Naoyuki Maruyama, Eiji Ando
