Embodiments Below, embodiments of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a frame of a steering lock, and a cylinder case 2 is rotatably provided. A knob 3 for rotational operation protruding from the frame 1 is fixed to the front surface of the cylinder case 2 by a pin 3'. The rotor 4 is inside the cylinder case 2.
The tumbler 4a protruding into the groove 2a of the cylinder case 2 is moved backward and rotated by inserting the key 5, as is known in the art, to perform the unlocking operation. An operating rod 7 for an ignition switch 6 is attached to the rear end of the rotor 4, and a cam 7a for a hanger 9 of a locking rod 8 is provided. The hanger 9 is constantly pressed downward by a spring 9'. The locking rod 8 operates integrally with the vertical movement of the hanger 9.

The frame 1 is provided with an electromagnetically actuated main actuator 10, and its main plunger 1
1 can freely approach and separate from the circumferential side of the cylinder case 2. In a check lever case 1' housed in a frame 1, a check lever 13 serving as a holding member for a locking rod 8 is swingably provided on the side of the cylinder case 2 with a movable pin 12 as a fulcrum. The key sensing part 13a can move forward and backward into the rotor 4 through the holes 2b and 4b of the cylinder case 2 and the rotor 4, and the other locking part 13b can be freely engaged with and disengaged from the engagement part 8a of the locking rod 8. The check lever 13 is constantly biased by a coil spring 14 in a direction in which the key sensing portion 13a enters the rotor 4. Coil spring 14 is cover 1
4'. The check lever 13 extends through the movement allowing space 11a of the main plunger 11, and is disposed so as to come into contact with the driving stepped portion 11b.

A sub-actuator 15 is provided in front of the main actuator 10, and a sub-plunger 17 that is attracted against a spring 16 when energized is arranged in a direction intersecting the main plunger 11. The main plunger 11 is provided with a flange-shaped stopper 18, the sub-plunger 17 is provided with a stopper plate 19 that engages with the stopper 18, and the stopper plate 19 is provided with a stopper of the main plunger 11. A notch 19a is formed to allow passage of 18.

In the above configuration, from the state shown in FIG.
a, 20b, 20c... and when they match the stored numbers, the controller 21 issues a matching signal and energizes the sub-actuator 15, which causes the sub-plunger 17 to be sucked against the spring 16. As a result, the stopper plate 19 is moved back from the locus of movement of the stopper 18 so that the stopper 18 passes through the notch 19a, and this state is maintained for a certain period of time.

During this time, the controller 21 outputs a signal for energizing the main actuator 10 for a certain period of time.
When the main actuator 10 is energized, the main plunger 11 moves backward while driving the check lever 13, and is held by a magnet built into the main actuator 10. and,
When the signal output from the controller 21 to energize the sub-actuator 15 is cut off after a certain period of time, the sub-plunger 17 is returned to its original position by the spring 16, and the stopper plate 19 is also returned to its original position. , and hold the main plunger 11 in the released position.

When the main plunger 11 is retracted, the driving step portion 11b drives the check lever 13 against the coil spring 14 to move it from the X position to the Y position in FIG. 6, whereby the key sensing portion 13a is activated. When the locking portion 13b is removed from the cylinder case 2,
is brought into pressure contact with the locking rod 8 and becomes ready for engagement.

In this state, when the cylinder case 2 is rotated via the knob 3, the tumbler 4 inside the cylinder lock
a is engaged with the groove 2a, the rotor 4 also rotates, and the ignition switch 6 is switched from the ACC position to the ON or START position, and the locking rod 8 is connected to the steering shaft (not shown) via the cam 7a. At this time, the locking part 13b of the check lever 13 engages with the engaging part 8a of the locking rod 8, and a lock signal is sent from the controller 21 to the actuator 10 while the car is stopped. Hold this position until

Next, for the locking operation, turn the knob 3 to the LOCK position and press a predetermined button from the keyboard 20, which sends a signal to the controller 21, which receives the signal from the vehicle speed sensor 22 when the car has stopped. After detecting the LOCK position by the lock position detection terminal 23 provided on the ignition switch 6, the sub actuator 15 is energized, and then the main actuator 10 is energized. As a result, the stopper plate 19 is attached to the main plunger 11.
The main plunger 11 returns to its original position close to the cylinder case 2, and the check lever 13
At the same time, when the key sensing part 13a returns to the position where it passes through the cylinder case 2 and engages in the rotor 4, the locking part 13b is released from the locking rod 8, and the locking rod 8 is lowered by the spring 9', and the steering shaft is closed. (not shown) to the locking position. Since the cylinder case 2 is prevented from rotating due to the engagement of the key sensing portion 13a, the knob 3 cannot be rotated.

When unlocking with the key 5, the rotor 4 is rotated while the check lever 13 is moved from the X position to the Z position in FIG. 6 using the key 5 via the key sensing portion 13a.

In addition, the CPU 21a provided in the controller 21
P- with a preset unlock number stored in it.
The ROM 21b, the interface 21c, the power supply circuit 21d, and the output circuit 21e that receives the output from the CPU 21a are connected, and a locking relay 27 and an unlocking relay are connected between the output circuit 21e and the main actuator 10. Connect relay 27'. Further, a relay 28 is connected between this output circuit 21e and the sub-actuator 15.

Effects As described above, the present invention includes a cylinder case rotatably provided within the frame of the steering lock, a knob for rotating the cylinder case, and a rotor rotatably operated by a key provided within the cylinder case. A check lever for holding the locking rod is swingably provided on the side of the cylinder case, and a spring is provided to bias the key sensing part into the rotor, and a main plunger driven by a main actuator is provided. The check lever is provided so as to pass through a space allowing movement of the main plunger, and the check lever is driven when the main plunger is driven by the main actuator, and the main plunger is driven by the main actuator. The locking rod is provided with a sub-actuator and a sub-plunger that selectively maintain the operation of the steering wheel in the locked position and the released position. It is possible to incorporate a check lever for holding the locking rod, and the check lever for holding the locking rod can be operated without any trouble during both operations.
At this time, the sub-plunger is actuated by a sub-actuator that selectively restrains and releases the operation of the main plunger, which is actuated by the main actuator that drives the check lever. Because of this, it has the advantage of being able to reliably prevent unauthorized unlocking when the vehicle is locked and accidental activation of the steering lock while driving.
