Patent ID: 7009479

Claim:
A steering column lock for a personal identification card system, comprising: a bi-directional solenoid actuator that linearly shifts a plunger, which is protruded at a lateral side of said bi-directional solenoid actuator; a lever including a blocking part and a pivot axis, which is perpendicular to a linear movement direction of said plunger, said lever being resiliently supported to depress said plunger into a coil part of said bi-directional solenoid actuator by contacting a protruded end of said plunger; an actuating plate integrally installed around said plunger; a permanent magnet mounted between said actuating plate and said coil part of said bi-directional solenoid actuator to provide a magnetic force to said actuating plate; a coil spring that resiliently supports said actuating plate to distance said actuating plate from said permanent magnet; and a cam shaft having a pivot axis, which is perpendicular to said pivot axis of said lever, said cam shaft including a cam whose pivot state is converted according to a pivot state of said blocking part of said lever.
