  • Patent number: 8376767
    Abstract: A locking device that prevents unauthorized removal of a power feeding plug from an inlet. The locking device is provided with a lock mechanism, which includes a lock member that locks the power feeding plug to the inlet, and an operation member, which is operated at least when shifting the lock mechanism to a lock state. The operation member applies an operation force to the lock member to mechanically move the lock member and shift the lock mechanism to a lock state.

  • Patent number: 8357001
    Abstract: A locking device that locks a power feeding plug to an inlet of an plug-in vehicle to restrict removal of the power feeding plug from the inlet. The locking device includes a housing coupled to the inlet. The housing covers a peripheral portion of the inlet and includes a hook port that receives the hook when the power feeding plug is inserted into the inlet. A lock bar, which is arranged in the housing, moves between a lock position, in which the lock bar locks the hook to the inlet, and an unlock position, in which the lock bar permits the hook to move relative to the inlet. The lock bar, when located at the lock position, blocks the hook, which is hooked to the inlet, to restrict removal of the housing from the inlet.

  • Publication number: 20130015951
    Abstract: A lock device for a power supplying plug arranged in a vehicle that performs wireless communication with an electronic key. The lock device includes a charge ECU that restricts unauthorized removal of the power supplying plug from an inlet of the vehicle. The vehicle includes antennas that transmit a wireless signal. A first one of the antennas relates to permission for removal of the power supplying plug. A second one of the antennas relates to unlocking or permission for unlocking of a door. A charge ECU stops transmitting the wireless signal from the first antenna when the vehicle is parked and the second antenna transmits the wireless signal. The charge ECU stops the transmission of the wireless signal related to the unlocking of the door when the wireless signal related to removal of the power supplying plug is transmitted.

  • Publication number: 20120238122
    Abstract: A power plug locking device that prevents unauthorized removal of a power plug from an inlet includes a lock member pivoted about its axis. The lock member is pivoted between a lock position, at which the lock member locks the power plug to the inlet, and an unlock position, at which the lock member releases the power plug from a state locked to the inlet. A manual operation unit is manually operated to pivot the lock member from the unlock position to the lock position. A position holding unit is formed to hold the lock member at the lock position and maintain the power plug in a locked state with the lock member.

  • Patent number: 8251734
    Abstract: A locking device that locks a power feeding plug to a power receiving connector, one of the power feeding plug and the power receiving connector including a hook, the other one of the power feeding plug and the power receiving connector including a catch, the locking device including a lock bar that is moved between a first lock position, at which it holds the hook on the catch and a first unlock position, at which it permits the hook to move away from the catch. A wire is moved between a second lock position, at which it is engaged with the lock bar and restricts movement of the lock bar to the first unlock position, and a second unlock position, at which it is disengaged from the lock bar and permits movement of the lock bar to the first unlock position. A motor is arranged at a position separated from the power receiving connector. A cam transmits the driving force of the motor to the wire.

  • Patent number: 8206172
    Abstract: A plug lock structure that locks a power feeding plug to an inlet, which is fixed to a power feeding subject. The inlet includes a catch. The power feeding plug includes a hook, hooked to the catch, and an operation portion, which separates the hook from the catch. The plug lock structure includes a lock member pivoted in a direction in which the lock member forces the hook against the catch and a direction in which the lock member moves away from the catch together with the hook. A lock block is moved between a first position, at which the lock block permits pivoting of the lock member when the hook moves from the hooked state, and a second position, at which the lock block restricts pivoting of the lock member by contacting the lock member when the hook moves from the hooked state.

  • Publication number: 20120083148
    Abstract: 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.

  • Publication number: 20110287649
    Abstract: 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.

  • Patent number: 6886426
    Abstract: In a shift lever apparatus, a shift position can be changed from a ā€œPā€ shift position only by turning a shift lever to a right side of a vehicle. Unless a brake is operated, it is possible to maintain a state in which a stopper portion is disposed in a right side of the vehicle in an abutting portion. Therefore, the abutting portion abuts the stopper portion, and the shift lever cannot be turned to the right side of the vehicle. When the brake is operated, a rotary plate is rotated in accordance that the shift lever turns to the right side of the vehicle. Accordingly, the abutting portion does not abut the stopper portion, and the shift lever can be turned to the right side of the vehicle.

  • Patent number: 6857335
    Abstract: A manipulation lever can be manipulated to select a first mode for automatically changing the drive range of an automatic transmission or a second mode for changing the drive range by manually manipulating the manipulation lever. The manipulation lever is shifted between the first mode in which a control lever moves mechanically with the manipulation lever and the second mode in which the control lever does not move with the manipulation lever. A first guide portion guides the manipulation lever and a second guide portion guides the clutch lever. When the manipulation lever is arranged at the drive position, the first and second guide portions permit the manipulation lever to be disengaged from the clutch lever. When the manipulation lever is arranged at positions other than the drive position, the first and second guide portions keep the manipulation lever to be engaged with the clutch lever.
