Patent number: 10287806Abstract: The latch device for the trunk lid of the vehicle includes an electric open lever that causes a ratchet to withdraw from a latch when the electric open lever rotates, and a release actuator that rotates the electric open lever. An output gear that rotates by driving force of the release actuator is provided near the electric open lever, a pair of a first cam projection and a second cam projection with phases shifted from each other by 180 degrees is provided at the output gear, and the output gear is configured such that when the output gear rotates by 180 degrees, the first cam projection abuts against and rotates the electric open lever, and rotation of the output gear is blocked by the second cam projection abutting against the rotated electric open lever.Type: GrantFiled: December 28, 2015Date of Patent: May 14, 2019Assignee: MITSUI KINZOKU ACT CORPORATIONInventors: Takaaki Mizuno, Nao Mizumoto, Tomokazu Ito

Patent number: 8403378Abstract: A base plate is fixed to one of a door and a vehicle body of a vehicle. A latch is pivotally secured to the base plate and engages with a striker of the other of the door and the vehicle body, thereby connecting the door to the vehicle body. A ratchet is pivotally secured to the base plate and engages with the latch to allow the door to be held in a closed position. The base plate is fixed to the door or vehicle body with bolts. The striker which engages with the latch is positioned substantially on a straight line between center of the two bolts.Type: GrantFiled: June 29, 2007Date of Patent: March 26, 2013Assignee: Mitsui Mining and Smelting Co., Ltd.Inventors: Hiroshi Okada, Satoru Nishizawa, Nao Mizumoto

Patent number: 8109542Abstract: A base plate is provided in one of a door and a vehicle body of a vehicle. A latch is pivotally secured to the base plate and engages with a striker of the other of the door and the vehicle body. A ratchet engages with the latch to allow the door to be held in a closed position. An emergency-operating portion is mounted to the base plate and manually operated at the interior of the vehicle, so that the ratchet is released from the latch, which is then released from the striker. The door can be opened.Type: GrantFiled: June 29, 2007Date of Patent: February 7, 2012Assignee: Mitsui Mining and Smelting Co., Ltd.

Patent number: 7517003Abstract: An opening and closing apparatus for an opening and closing body of a vehicle. The opening and closing apparatus includes a reciprocating member movable along a plane perpendicular to a hinge shaft. A connecting member is provided having a first end section fixed to the opening and closing body, and a second end section pivotally attached to the reciprocating member through a connecting shaft. The opening and closing body is moved to open and close through the connecting member upon a movement of the reciprocating member. In the opening and closing apparatus, the connecting member includes two side wall sections apart from each other in a direction parallel with the axis of the connecting shaft. A suppression member is disposed to a stationary body in the vehicle and so engaged between the two side wall sections as to be relatively movable to the connecting member.Type: GrantFiled: July 6, 2006Date of Patent: April 14, 2009Assignee: Mitsui Mining & Smelting Co., Ltd.Inventors: Hiroshi Okada, Nao Mizumoto

Patent number: 7243976Abstract: An opening and closing apparatus for an opening and closing body of a vehicle. The opening and closing apparatus includes a reciprocating member connected at its connecting portion to a motor so as to be moved to reciprocate along a plane perpendicular to a hinge shaft, the reciprocating member having a side surface parallel with the plane perpendicular to the hinge shaft. A connecting member is provided having a first end section pivotally attached to an end portion of the reciprocating member, and a second end section fixed to the opening and closing body. A deflection-suppressing device is provided to a stationary body connected to the vehicle body. A part of the side surface of the reciprocating member is slidably contacted with the deflection-suppressing device and is located between the connecting portion of the reciprocating member and the connecting member.Type: GrantFiled: July 6, 2006Date of Patent: July 17, 2007Assignee: Mitsui Mining and Smelting Co., Ltd.Inventors: Hiroshi Okada, Nao Mizumoto
