  Preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings.

(Overall structure of steering lock device)
1 and 2, reference numeral 1 indicating the whole schematically shows the overall configuration of the steering lock device for a vehicle according to this embodiment. In FIG. 1, the bracket 200 that fixes the steering column 100 is partially broken. In the following description, the direction in which the key K is inserted (right side in FIG. 2) is referred to as the rear, the direction in which the key K is removed (left side in FIG. 2) is referred to as the front, and the key hole of the key K from the front. It is called up, down, left and right.

  As shown in FIGS. 1 and 2, the steering lock device 1 is mainly configured by a key portion 10, a steering lock portion 20, an interlock unit 30, and an ignition switch unit 40. The steering lock device 1 includes a case member 2 that is integrally processed and formed of a metal material such as zinc die casting.

(Key part configuration)
As shown in FIG. 2, a key cylinder 11 is accommodated inside the key portion 10 formed at the front portion of the case member 2. The key cylinder 11 includes a cylindrical cylinder 12 and a cylindrical rotor 13 that is rotatably accommodated in the cylinder 12. The rotor 13 is formed with a key hole 13a for inserting the key K along the axial direction.

  As shown in FIG. 2, a plurality of tumblers 14,..., 14 that are long in the rotor radial direction are accommodated inside the rotor 13 so as to be movable along the rotor axial direction. The free end portion of the tumbler 14 protrudes from the outer peripheral surface of the rotor 13 and engages with the inner peripheral surface of the cylinder 12 in a state where the regular key K is not inserted. Thereby, rotation of the rotor 13 is controlled. On the other hand, when the regular key K is inserted into the rotor 13, each of the tumblers 14 is engaged with the end surface of the key groove shape of the key K, and all the tumblers 14 are retracted from the outer peripheral surface of the rotor 13. Thereby, rotation operation of the rotor 13 is attained.

  As shown in FIG. 2, a slide piece 15 is arranged at the lower part on the front side of the rotor 13 so as to be movable in the rotor radial direction. The outer surface of the slide piece 15 is curved with the same curvature as the outer peripheral surface of the rotor 13. The rotor 13 and the slide piece 15 rotate integrally within the key cylinder 11. With the regular key K inserted into the rotor 13, the end of the slide piece 15 abuts against a part of the key K, so that the movement toward the rotor center is restricted.

  As shown in FIG. 2, a long antilock lever 16 that is a movable member is disposed in parallel to the central axis of the key cylinder 11 below the key cylinder 11, and is vertically moved around the support shaft 16c. It is supported so that it can swing in the direction. A front end portion 16 a that is bent toward the slide piece 15 is formed at the front end of the anti-lock lever 16 on the key hole side. A rear end portion 16 b that can be locked with the steering lock portion 20 is formed at the rear end of the antilock lever 16 by bending.

  An elastic force acts on the front end portion 16a of the anti-lock lever 16 in a direction (upward direction) toward the slide piece 15 by a spring or the like (not shown). When the rotor 13 is in the “LOCK” position or the key K is removed from the key cylinder 11, the elastic force acts to raise the front end portion 16a of the antilock lever 16, and at the same time, the rear end portion 16b lowers. The lock state is released (steering lock permission state).

  A camshaft 17 is connected to the rear shaft 13b of the rotor 13 as shown in FIG. The camshaft 17 has a small-diameter cylindrical inner cylinder portion 17a and a large-diameter cylindrical outer cylinder portion 17b. The inner cylinder part 17a and the outer cylinder part 17b are connected and integrated at the front end edge to form an inner / outer double cylinder structure. A rear shaft 13b of the rotor 13 is fitted and fixed to the inner peripheral surface of the inner cylinder portion 17a. A rear end portion of the inner cylinder portion 17 a protrudes from the case member 2 and is connected to the ignition switch unit 40. Thereby, when the rotor 13 of the key cylinder 11 is rotated by the regular key K, the ignition switch unit 40 is operated via the camshaft 17. A cam surface 17c that slides with the steering lock portion 20 is formed at the lower portion of the one outer cylinder portion 17b.

  As shown in FIG. 2, a torsion spring 18 is accommodated in a space formed between the inner cylinder portion 17 a and the outer cylinder portion 17 b of the camshaft 17. One end of the torsion spring 18 is locked to the outer cylinder portion 17b. When the rotor 13 of the key cylinder 11 reaches the “ON” position by rotating the key K, the other end of the torsion spring 18 is locked to the case member 2. When the key K is rotated to the “START” position side, a spring force in a direction to return from the “START” position to the “ON” position acts on the camshaft 17.

(Configuration of steering lock)
As shown in FIG. 2, the steering lock portion 20 formed at the lower portion on the rear side of the case member 2 includes a lock bar 21, a compression spring 22, and a slider 23. The lock bar 21 is formed in a long plate shape from a highly rigid metal material. The lock bar 21 is accommodated in the case member 2 so as to be movable back and forth in a direction parallel to the rotation axis of the rotor 13. The distal end portion of the lock bar 21 is always disposed in a state of projecting from the rear portion of the case member 2 toward the steering column 100 by a compression spring 22 supported by the spring receiving portion 2 f in the case member 2.

  As shown in FIG. 2, a groove 21 a is formed at the upper end of the case member 2 near the front portion of the lock bar 21. A lower end portion of a slider 23 made of a block body is fitted in the groove portion 21a so as to be able to reciprocate in the rotor axial direction. The upper rear end surface of the slider 23 comes into contact with the rear inner wall 2 a of the case member 2, so that the lock bar 21 is prevented from coming off from the case member 2.

  As shown in FIG. 2, a follower portion 23 a that contacts and follows the cam surface 17 c of the camshaft 17 is integrally formed at an upper portion near the rear side of the slider 23. A locking projection 23b that can be locked to the rear end 16b of the antilock lever 16 is formed on the front upper portion of the slider 23. Since the steering lock portion 20 configured as described above is disposed in parallel with the rotor rotation axis of the key portion 10, the steering lock device 1 can be reduced in size.

(Operation of the steering lock device)
Here, referring to FIG. 3, FIG. 3 shows a locked state in which the rotation of the steering shaft 101 is blocked by the lock bar 21 of the steering lock device 1. One end of the semicircular arc-shaped bracket 200 is supported by the hinge block portion 2b of the case member 2 through a hinge shaft 201 so as to be opened and closed. The bracket 200 is opened, the steering column 100 is sandwiched between the case members 2, and the bracket 200 is closed, and the other end of the bracket 200 is fixed to the boss block 2 c of the case member 2 via the bolt 202. A column 100 is attached to the steering lock device 1.

  At the lock position where the lock bar 21 advances to the steering column 100 side, the tip of the lock bar 21 is engaged with the recess 103 of the spline boss 102 fitted to the steering shaft 101, whereby the rotation of the steering shaft 101 is performed. Is regulated. At the unlock position where the lock bar 21 is retracted from the recess 103 of the spline boss 102, the engagement between the lock bar 21 and the spline boss 102 is released and the rotation of the steering shaft 101 is allowed.

  According to the configuration of the steering lock portion 20, in the state where the key K is removed from the key hole 13a, the movement of the slide piece 15 is not restricted and is pushed up by the front end portion 16a of the antilock lever 16, and the antilock lever 16 The rear end portion 16b descends. Accordingly, the locking projection 23b of the slider 23 and the rear end portion 16b of the antilock lever 16 cannot be locked, and the lock bar 21 advances to the lock position by the elastic extension force of the compression spring 22, and the lock bar 21 When the upper rear end surface of the slider 23 fitted in the groove portion 21a comes into contact with the rear inner wall 2a of the case member 2, the lock bar 21 is held at the lock position.

  In the process in which the regular key K is inserted into the keyhole 13a and the rotor 13 rotates from the “LOCK” position to the “ACC” position, the outer surface of the slide piece 15 moves to a position that coincides with the outer peripheral surface of the rotor 13, While pushing down the front end portion 16a of the antilock lever 16, the rear end portion 16b of the antilock lever 16 is raised. At this time, the camshaft 17 rotates in conjunction with the rotation of the rotor 13, and the locking projection 23 b of the slider 23 moves forward together with the follower portion 23 a that is driven by contacting the cam surface 17 c of the camshaft 17. At the same time, the lock bar 21 connected to the slider 23 via the groove 21a is retracted to the unlock position. When the rotated rotor 13 reaches the “ACC” position, the locking projection 23b of the slider 23 is locked to the rear end portion 16b of the antilock lever 16, so that the slider 23 is held and the lock bar 21 is also held in the unlocked position. As a result, after the key K is rotated to the “ACC” position, the steering lock is anti-locked so as not to be erroneously activated.

(Configuration of protector for theft prevention)
The overall configuration of the steering lock device 1 configured as described above is not limited to the illustrated example. The first basic configuration of the steering lock device 1 includes a configuration in which the lock bar 21 is arranged so as to be movable in parallel with respect to the rotation axis of the rotor 13 of the key unit 10, and on the extension line in the moving direction of the lock bar 21. A protector 24 that crosses and covers the outer wall portion of the case member 2 is provided.

  Referring to FIG. 4, FIG. 4 shows the external shape of the protector 24 that prevents unauthorized unlocking. The protector 24 has an upper surface and a rear surface that are open, and is formed in a box shape that covers the outer wall portion of the steering lock portion 20. The protector 24 according to the illustrated example is made of, for example, a magnetic metal material having a thickness of about 2 mm, and is integrally formed of a ferrous material such as cold rolled steel, hot rolled steel, or carbon steel through a forging process such as press working. Is done.

  As shown in FIGS. 2 and 4, the external structure of the protector 24 is an inclined bottom surface portion that covers the lower wall portion of the case member 2 formed along the extension line in the direction in which the lock bar 21 is retracted from the steering column 100. 24a and the horizontal bottom surface part 24b, the front part 24c which covers the front wall part rising from the lower wall part of the case member 2, the left side part 24d which covers the left wall part rising from the lower wall part of the case member 2, and the case member 2 It has four shielding surface portions including a right side surface portion 24e covering the right wall portion rising from the lower wall portion. Of the four shielding surface portions of the protector 24, the free end portions of the three shielding surface portions of the front surface portion 24c, the left side surface portion 24d, and the right side surface portion 24e are formed on the periphery of the steering lock portion 20 of the case member 2. It is covered with the cover part 2g.

  Since the protector 24 that covers the outer wall portion of the steering lock portion 20 in the case member 2 is made of a magnetic metal material, an unauthorized person may pull the lock bar 21 from the outer wall portion of the case member 2 to the unlock position using a strong magnet. However, the magnetic force is induced by the protector 24 and does not act on the lock bar 21. For this reason, fraud using a magnet can be prevented. Since the front surface portion 24c of the protector 24 is disposed on the extension line where the lock bar 21 is retracted, illegal acts using the magnet from the front surface portion 24c can be more effectively prevented.

  As shown in FIGS. 4 and 5, bolt holes 25 a constituting a part of the attachment portion 25 for attaching to the case member 2 are formed in the left side surface portion 24 d and the right side surface portion 24 e of the protector 24. The protector 24 is fastened and fixed to the case member 2 by a one-way countersunk bolt 26 through a bolt hole 25a. A seat rod 24 f that accommodates the head of the one-way countersunk bolt 26 is formed on the insertion side opening peripheral portion of the bolt hole 25 a of the protector 24. The counterbore 24f is formed in a tapered cross-sectional shape that gradually expands concentrically toward the surface side of the protector 24.

  According to the configuration of the protector 24, the free end portions of the front surface portion 24 c, the left side surface portion 24 d, and the right side surface portion 24 e of the protector 24 are attached to the cover portion of the case member 2 in a state where the protector 24 is attached to the case member 2. In addition to being covered with 2 g, the head of the one-way countersunk bolt 26 enters the seat rod 24 f and is disposed at a position deeper than the surface of the protector 24. As a result, an illegal attack on the free end portions of the front surface portion 24c, the left side surface portion 24d, and the right side surface portion 24e of the protector 24 using a bar or the like and an unauthorized attack on the one-way countersunk bolt 26 cannot be performed. The omission of 24 can be effectively prevented.

  Further, in the protector 24 according to the illustrated example, the head of the one-way countersunk bolt 26 has, as shown in FIG. 5, a longitudinal groove 26a that engages with a driver only by clockwise tightening and a longitudinal groove 26a as viewed from the front. A tapered groove 26b that gradually becomes shallower in the counterclockwise direction is formed. Thereby, it becomes extremely difficult to loosen and take out the one-way countersunk bolt 26 using a normal tool, and an illegal act of removing the one-way countersunk bolt 26 can be effectively prevented.

(Configuration of anti-theft deadlock member)
The second basic configuration of the steering lock device 1 according to this embodiment includes an antitheft deadlock member built in the case member 2 in addition to the configuration in which the protector 24 is provided outside the case member 2. That is.

  Referring to FIGS. 2 and 6, these drawings show the internal structure of the steering lock portion 20 for preventing an illegal act of a person who attempts to unlock the steering lock device 1 illegally. According to the illustrated example, the inside of the case member 2 communicates in a direction orthogonal to the moving space formed along the extension line on which the lock bar 21 moves back and forth, and the lock bar 21 cannot be operated in the locked state. A component storage chamber 2d for storing a deadlock member to be locked is formed. A slide member 27, which is a deadlock member, is accommodated in the component accommodating chamber 2d so as to be movable in the vertical direction.

  As shown in FIGS. 2 and 6, a stopper insertion hole 2e communicating with the component housing chamber 2d is formed inside the case member 2. The stopper insertion hole 2 e is arranged in a direction parallel to the moving direction of the lock bar 21 so as to intersect the moving direction of the slide member 27. In this stopper insertion hole 2e, a stopper member 28, which is a deadlock member that operates the slide member 27, is accommodated so as to be movable in the rotor axial direction.

  The slide member 27 is made of a nonmagnetic material, and prevents the lock bar 21 from moving from a locked position where rotation of the steering shaft 101 is prevented to an unlock position where rotation of the steering shaft 101 is allowed. As shown in FIGS. 2 and 6, the slide member 27 is located at a portion where the concave spring receiving portion 27 b that houses the coil spring 27 a and the spring receiving portion 27 b intersect, and the stopper member 28 is fitted and engaged. An engagement groove 27c is formed. The slide member 27 is held by the stopper member 28 while being urged by the coil spring 27a toward a moving space formed along an extension line on which the lock bar 21 moves backward.

  One stopper member 28 is made of a nonmagnetic material, like the slide member 27. As shown in FIGS. 2 and 6, an annular flange-shaped spring receiving portion 28 b that supports the coil spring 28 a is formed on the outer peripheral surface of the stopper member 28. According to the illustrated example, the free end portion of the front surface portion 24 c of the protector 24 is formed as a holding piece that holds the stopper member 28 at a position where the stopper member 28 is not operated. The tip of the stopper member 28 engages with the engaging groove 27c of the slide member 27, and the spring receiving portion 28b of the stopper member 28 comes into contact with the holding piece of the protector 24 so that the movement of the stopper member 28 is prohibited. The slide member 27 is held in a state of being biased by the coil spring 28a toward a position where the stopper member 28 is allowed to move.

(Operation of deadlock member)
Next, the operation of the deadlock member configured as described above will be described with reference to FIG. As shown in FIG. 6A, when the steering shaft 101 is locked as shown in FIG. 6A, the slide member 27 and the stopper member 28 are held in an inoperative state by the holding piece of the protector 24. ing.

  Now, when the protector 24 is removed from the case member 2 as shown in FIG. 6B due to an unauthorized act of a person who intends to unlock the steering lock device 1, the spring receiving portion 28b of the stopper member 28 and the protector 28 are protected. The state in which the holding pieces 24 are in contact with each other is released, and the stopper member 28 instantaneously moves in the direction of the rotor axis away from the slide member 27 by the spring force of the coil spring 28a. At the same time, the tip of the stopper member 28 is detached from the engagement groove 27 c of the slide member 27.

  As a result, the slide member 27 immediately falls into a moving space formed along the extension line on which the lock bar 21 is retracted by the spring force of the coil spring 27 a, and the spring receiving portion of the case member 2 that supports the compression spring 22. 2f. As a result, the slide member 27 closes the moving space formed along the extended line in the direction in which the lock bar 21 retracts from the steering column 100, so that the lock bar 21 is held at the lock position, and the lock position is unlocked from the lock position. The lock bar 21 is prevented from moving (deadlock state).

  According to the deadlock structure according to this embodiment, inside the case member 2, the three spaces of the movement space of the lock bar 21, the component storage chamber 2 d, and the stopper insertion hole 2 e intersect each other, and The lock bar 21, the slide member 27, and the stopper member 28 are movably accommodated in the spaces. With such a configuration, it becomes difficult to remove these components illegally, and excellent crime prevention performance against vehicle theft can be obtained.

  According to this deadlock structure, the free end portion of the front surface portion 24c of the protector 24 is covered with the cover portion 2g of the case member 2, and the deadlock member is disposed inside the case member 2 corresponding to the free end portion. Therefore, the front part 24c of the protector 24 becomes an obstacle and it is difficult to break the deadlock member. Thereby, the outstanding crime prevention performance with respect to vehicle theft is obtained.

  From the above, the case member 2 of the steering lock device 1 is mounted within a predetermined time, for example, within 2 minutes after the destruction of the person who intends to unlock the steering lock device 1 is attempted. It is possible to sufficiently satisfy an evaluation standard called Thatcham that must not be removed illegally.

  As is clear from the above description, the steering lock device of the present invention has been described based on the above embodiment, but the present invention is not limited to the above embodiment and illustrated examples, and departs from the gist thereof. It is possible to implement in various embodiments as long as they are not. In the present invention, for example, other modifications as shown below are possible.

(1) In the illustrated example, the configuration example in which the tip of the stopper member 28 is engaged with the engagement groove 27c of the slide member 27 to hold the slide member 27 is illustrated, but the present invention is not limited to this. For example, the slide member 27 may be held by removing the engagement groove 27 c of the slide member 27 and engaging the tip of the stopper member 28 with the lower wall portion of the slide member 27.
(2) In the illustrated example, the sliding member 27 is formed in a moving space formed along an extension line in which the lock bar 21 is retracted by the spring force of the coil spring 27a when the engagement state with the stopper member 28 is released. Although the example of a structure which falls to is illustrated, it is not limited to this. As an example of the modification, for example, when the engagement state with the stopper member 28 is released, the slide member 27 may be dropped by its own weight.
(3) In the illustrated example, the free end portions of the front surface portion 24c, the left side surface portion 24d, and the right side surface portion 24e of the protector 24 are covered with a cover portion 2g formed on the periphery of the steering lock portion 20 of the case member 2. However, it is not limited to this. As an example of the modified example, for example, the cover member 2g of the case member 2 is excluded, and the front end portion 24c, the left side surface portion 24d, and the free end portions of the right side surface portion 24e of the protector 24 are exposed to the outside. Alternatively, the cover 2g may be formed only on the portion of the case member 2 corresponding to the position of the deadlock member.
(4) In the illustrated example, the configuration example in which the free end portion of the front surface portion 24c of the protector 24 is used as a holding piece that holds the stopper member 28 at a position where the movement of the slide member 27 is prohibited is illustrated. Of course, the holding piece can be formed on a surface portion other than the front surface portion 24c of the protector 24, for example, in accordance with the arrangement positions of the slide member 27 and the stopper member 28, for example.
