Cylinder lock and key device

Claim 1

A cylinder lock and key device in combination with an ignition switch and a wireless lock device, the cylinder lock and key device comprising: a rotor rotatable from a locked off position to an unlocked on position; a cylinder lock body surrounding said rotor and including a coil mounting portion forming a front end portion of said cylinder lock body; a primary coil wound on a coil bobbin mounted in said coil mounting portion, said primary coil being connected to a control device for energizing said primary coil when said rotor is in the unlocked on position; shielding means mounted in said cylinder lock body for preventing magnetic flux of the primary coil from flowing into the cylinder lock body, the shielding means being arranged between the coil mounting portion and the primary coil; and a key having a secondary coil connected to a power cell in a charging circuit, said key being insertable into the cylinder lock body through a central opening in the coil bobbin, said key operable to rotate said rotor to the unlocked on position thereby allowing said control device to energize said primary coil to achieve magnetic coupling of the primary and secondary coils to charge the power cell, the power cell being for powering a signal transmitting circuit for transmitting a signal to the wireless lock device separate from the cylinder lock and key device.
