Patent number: 8753136Abstract: A power feeding plug locking device that locks a power feeding plug to a power feeding inlet. The power feeding inlet is arranged in a machine including a door that can be locked. The locking device includes a lock mechanism of which operational state is shifted between a lock state and an unlock state. The lock mechanism prohibits removal of the power feeding plug from the inlet in the lock state and allows removal of the power feeding plug from the inlet in the unlock state. An operation unit is operated when switching the operational state of the lock mechanism between the lock state and the unlock state. A door lock state confirmation unit confirms whether the door of the machine is locked. A controller controls the operational state of the lock mechanism based on the operation of operation unit whether the door is locked.Type: GrantFiled: September 21, 2011Date of Patent: June 17, 2014Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Takahiro Hirashita, Keiji Kahara, Toshiharu Katagiri, Keigo Nishimoto, Tomohiro Inoue

Patent number: 8698349Abstract: A locking device for a power feeding plug installed in a vehicle. The vehicle includes an inlet that receives the power feeding plug to charge a battery, which powers a motor. A door antenna transmits a verification signal to an electronic key. The locking device includes a lock bar moved between lock and unlock positions. The lock bar blocks the power feeding plug, which is attached to the inlet, when located at the lock position to prohibit removal of the power feeding plug from the inlet. An inlet antenna transmits the verification signal to an area that includes the inlet. The inlet antenna and door antenna are arranged at different locations. A controller moves the lock bar when verification of the electronic key is accomplished in response to the verification signal from the inlet antenna.Type: GrantFiled: May 13, 2011Date of Patent: April 15, 2014Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Naoto Kurumizawa, Keiji Kahara, Toshiharu Katagiri
