  An object of the present invention is to obtain a steering lock device that can reduce the size of the device in consideration of the above facts.

A steering lock device according to a first aspect of the present invention includes a key rotor that is rotated between a locked position and an unlocked position by a rotation operation using a key, and that can be inserted and removed in a state where the key is disposed in the locked position. An ignition cylinder having a control position for restricting rotation of a steering shaft of the vehicle and a release position for releasing the restriction, and being urged in the direction of the restriction position, and the key rotor is A lock member that is moved to the release position by the key rotor when rotated to the lock position, and the lock member that connects the lock member and the ignition cylinder when the lock member is moved to the release position. Is held in the release position, and the key is pulled out from the key rotor. Wherein a coupling means for releasing the connection, wherein the connection means, the provided ignition cylinder, with in a state in which the key is inserted into the key rotor is disposed on the movement locus of the locking member, the key rotor A movement preventing member that is movable outside the movement locus in a state where the key is pulled out, and the movement on the movement locus when the lock member is moved to the release position. And an engagement portion that engages with the blocking member and is released when the movement blocking member can move out of the movement locus .

In the steering lock device according to claim 1, when the key is inserted into the key rotor of the ignition cylinder and the key rotor is rotated from the lock position to the unlock position by the key, the lock member is moved to the release position by the key rotor and connected. The lock member and the ignition cylinder are connected by the means. Thereby, the lock member is held at the release position. On the other hand, the key rotor is rotated from the unlocked position to the locked position, when the key is withdrawn from the key rotor, the connection between the locking member and the ignition cylinder by the coupling member Ru is released. More specifically, when the key is inserted into the key rotor, the movement preventing member provided in the ignition cylinder is arranged on the movement locus of the lock member. When the key rotor is rotated from the lock position to the unlock position and the lock member is moved to the release position, the engaging portion provided on the lock member is engaged with the movement preventing member. Thereby, a lock member and an ignition cylinder are connected. Further, when the key rotor is rotated to the lock position and the key is pulled out from the key rotor, the movement blocking member can move out of the movement locus of the lock member. For this reason, the engagement between the engagement portion provided on the lock member and the movement preventing member is released, and the connection between the lock member and the ignition cylinder is released. Thereby, the lock member is moved to the restriction position by the urging force acting on itself.

  Here, in this steering lock device, the lock member and the ignition cylinder are connected by the connecting means as described above, so that the lock member is held at the release position. Therefore, unlike the conventional steering lock device, it is not necessary to secure a space for swinging the long locking lever, and it is sufficient to secure a space for the lock member to move, so the device can be downsized. .

A steering lock device according to a second aspect of the present invention is the steering lock device according to the first aspect , wherein the engaging portion is movable between a first position and a second position with respect to the lock member, While being urged to the first position, the lock member is moved to the second position while being moved from the restriction position to the release position, and then moved to the second position, and the lock member is moved to the release position. When it reaches, it is moved to the first position by the urging force to engage with the movement preventing member, and the engagement is released by allowing the movement preventing member to move out of the movement locus. It is said.

In the steering lock device according to claim 2, the engagement portion provided in the lock member is provided in the ignition cylinder while the lock member is moved from the restriction position to the release position in accordance with the rotation operation of the key rotor by the key. It hits the movement blocking member and is moved to the second position. When the lock member reaches the release position, the engagement portion is moved to the first position by the urging force acting on the lock member and engages with the movement blocking member. Thereby, an ignition cylinder and a lock member are connected. Further, when the key is pulled out from the key rotor and the movement preventing member can move out of the movement locus of the lock member, the engaging portion is disengaged from the movement preventing member. Thereby, the connection between the ignition cylinder and the lock member is released.

The steering lock device according to a third aspect of the present invention is the steering lock device according to the first or second aspect , wherein the lock member is moved along the axial direction of the key rotor.

In the steering lock device according to the third aspect , the lock member is moved along the axial direction of the key rotor. Therefore, the movement space of the lock member does not unnecessarily expand in the radial direction of the key rotor, and the external dimensions of the device along the radial direction of the key rotor can thereby be reduced.

<First Embodiment>
FIG. 1 is an exploded perspective view showing the configuration of a steering lock device 10 for a vehicle according to a first embodiment of the present invention. 2 to 5 show the configuration of the steering lock device 10 in cross-sectional views. In FIG. 2 to FIG. 5, hatching of some members is omitted for convenience of explanation.

  The steering lock device 10 includes a lock body 12 as a vehicle body attachment member attached to a steering post (not shown) of a vehicle. The lock body 12 has a pair of fixing pieces 14 and 16 fixed to the steering post. is doing. The pair of fixed pieces 14 and 16 are each formed in a semi-cylindrical shape, and are configured to be cylindrical when combined. Each of the pair of fixed pieces 14 and 16 is rotatably connected at one end in each bending direction by a support shaft 18, and is fastened at the other end in each bending direction by a bolt 20. It is fixed to the outer periphery of the steering post.

  In addition, a main body 22 constituting the lock body 12 is integrally connected to one fixed piece 14. The main body portion 22 is formed in a bottomed cylindrical shape, and the inside of the cylinder is a cylinder accommodation hole 24, and an ignition cylinder 26 is accommodated in the cylinder accommodation hole 24.

  The ignition cylinder 26 has a rotor case 28 that is formed in a cylindrical shape and is fitted coaxially in the cylinder accommodation hole 24. As shown in FIG. 6, the cylinder of the rotor case 28 has a rotor housing hole 30, and a rotor body 32 that is formed in a columnar shape and forms a key rotor is coaxially formed in the rotor housing hole 30. Contained. The rotor main body 32 is rotatably supported by the inner peripheral portion of the rotor case 28, and is prevented from being pulled out to one axial direction side (the arrow A direction side in FIGS. 2 to 5) and the other axial direction side (FIG. 2 to FIG. 2). In FIG. 5, it can be moved in the direction of arrow B).

  An insertion port 36 for the key 34 is formed at one end in the axial direction (end on the arrow A direction side) of the rotor body 32 disposed on the opening side of the cylinder housing hole 24. A plurality of tumbler accommodation holes 38 are formed in the intermediate portion in the axial direction of the rotor body 32, and tumblers 40 are accommodated in the tumbler accommodation holes 38, respectively. These tumblers 40 allow rotation of the rotor body 32 relative to the rotor case 28 only when the regular key 34 is inserted into the rotor body 32 from the key insertion port 36.

  The rotor body 32 can be rotated between the LOCK position (lock position, position shown in FIG. 7) and the ACC position (unlock position, position shown in FIG. 8) by rotating the key 34, and the ACC position can be changed. Via the ON position (position shown in FIG. 9) set on the opposite side to the LOCK position, and the START position (not shown) set on the opposite side to the ACC position via the ON position. ing. Further, the key 34 is configured such that when the rotor body 32 is in the ACC position, the ON position, and the START position, the tumbler 40 restricts the escape from the rotor body 32, and the rotor body 32 is in the LOCK position. The key 34 can be inserted into and removed from the rotor main body 32 only in the state of being located at the center.

  On the other hand, a camshaft 42 as a cam member formed in a columnar shape is provided between the ignition cylinder 26 and the bottom wall 22 </ b> A of the main body 22 inside the cylinder accommodation hole 24. The camshaft 42 is disposed coaxially with the rotor body 32 and is rotatably supported by the inner peripheral portion of the cylinder accommodation hole 24. A torsion spring 44 is accommodated inside the cam shaft 42, and the cam shaft 42 is always urged toward the LOCK position by the torsion spring 44. A spiral inclined surface 46 (see FIGS. 2 to 5) is formed on the outer peripheral portion of the camshaft 42. The inclined surface 46 corresponds to a plate lock 64 described later.

  A connecting portion 48 projects from the end of the camshaft 42 on the rotor body 32 side. The connecting portion 48 is connected to a connecting hole 50 formed at the other axial end of the rotor main body 32 by so-called spline fitting, whereby the camshaft 42 and the rotor main body 32 cannot be rotated relative to each other, and It is linked so that it can move relative to the direction.

  A torsion coil spring 52 is disposed between the tip of the connecting portion 48 and the bottom wall of the connecting hole 50, and the torsion coil spring 52 urges the rotor body 32 toward one side in the axial direction. . For this reason, the rotor main body 32 is normally arranged at the position shown in FIG. 2, but when it is pushed by the key 34 inserted in the rotor main body 32, the axis line resists the urging force of the torsion coil spring 52. It moves to the other direction side (the arrow B direction side in FIGS. 2 to 5).

  Note that an ignition switch 54 is provided on the opposite side of the camshaft 42 via the bottom wall 22A of the main body 22. The ignition switch 54 is connected to the rotor body 32 by a connecting rod 56 that passes through the bottom wall 22A and the camshaft 42, and the connection of contacts (not shown) is switched as the rotor body 32 rotates.

  On the other hand, a cylindrical stopper pin 86 provided in the rotor case 28 is provided at the other axial end of the rotor main body 32 disposed on the inner side of the cylinder housing hole 24 (the arrow B direction side in FIGS. 2 to 5). Are facing each other. The stopper pin 86 is fitted coaxially and movably in the axial direction into a circular through hole 88 formed at the other axial end of the rotor case 28 (the end on the arrow B direction side in FIGS. 2 to 5). ing. Further, a circular through hole 90 is formed at a position facing the stopper pin 86 on the side wall 22B of the main body portion 22 of the lock body 12.

  Here, in a state where the rotor body 32 is located at the LOCK position shown in FIG. 7, the ON position shown in FIG. 9, and the START position (not shown), the stopper pin 86 has one end in the axial direction thereof (the lower side in each figure above). When the end) hits the outer peripheral portion of the rotor body 32, the rotor case 28 is prevented from moving inward in the radial direction, and is held at the extraction preventing position. In this state, the other end of the stopper pin 86 in the axial direction is fitted into the through hole 90 of the main body 22, so that the displacement of the ignition cylinder 26 with respect to the lock body 12, that is, from the cylinder housing hole 24 of the ignition cylinder 26. The configuration is such that the escape is restricted.

  In addition, an insertion hole 92 into which the other axial end of the stopper pin 86 can be inserted is formed in the outer peripheral portion of the rotor body 32, and this insertion hole 92 is in a state where the rotor body 32 is located at the ACC position. It is provided so as to face the stopper pin 86. For this reason, as shown in FIG. 8, in a state where the rotor main body 32 is located at the ACC position, the stopper pin 86 can be moved to the extraction allowable position (see the dotted line in FIG. 8). When the stopper pin 86 is moved to the extraction allowance position, one end of the stopper pin 86 in the axial direction is pulled out from the through hole 90 of the main body 22, and the restriction on the displacement of the ignition cylinder 26 by the stopper pin 86 is released. Is done.

  On the other hand, a lever 94 is provided on the opposite side of the rotor body 32 from the stopper pin 86. The lever 94 has a long shape along the circumferential direction of the rotor main body 32, and is disposed to face the outer peripheral portion of the rotor main body 32. A concave portion 96 is formed at the center of the lever 94 in the longitudinal direction on the side opposite to the rotor body 32, and a support portion 98 provided on the outer peripheral portion of the rotor case 28 enters the concave portion 96. As a result, the lever 94 is supported by the rotor case 28 and can swing about the support portion 98 as a fulcrum.

  An interference projection 100 that protrudes toward the rotor body 32 is formed at one end in the longitudinal direction of the lever 94 (the end on the arrow C direction side in FIGS. 7 to 9). The lever 94 uses the support 98 as a fulcrum. By swinging, the interference protrusion 100 is engaged (contacted) or separated from the outer peripheral portion of the rotor main body 32. Further, the other end portion in the longitudinal direction of the lever 94 (the end portion on the arrow D direction side in FIGS. 7 to 9) is disposed between the inner peripheral portion of the cylinder housing hole 24 and the outer peripheral portion of the rotor body 32. A connecting projection 102 that protrudes toward the rotor main body 32 is formed at the other longitudinal end of the lever 94. The connecting protrusion 102 corresponds to a leaf spring 104 as an urging member.

  The leaf spring 104 is formed in a long band shape by a plate-shaped spring material. The leaf spring 104 is provided along the circumferential direction between the inner peripheral portion of the rotor housing hole 30 and the outer peripheral portion of the rotor main body 32 in a state of being curved in an arc shape, and a part of the outer peripheral portion is a rotor. The housing hole 30 is in close contact with the inner periphery. One end portion of the leaf spring 104 in the longitudinal direction is connected (supported) to the other end portion in the axial direction of the stopper pin 86 described above, and the stopper pin 86 is moved in the direction of the extraction preventing position described above by the spreading force of the leaf spring 104. It is energized.

  Further, a connecting hole is formed at the other longitudinal end of the leaf spring 104, and the connecting protrusion 102 of the lever 94 is inserted into this connecting hole. Thereby, the other longitudinal end of the leaf spring 104 is coupled (supported) to the coupling protrusion of the lever 94. That is, the other longitudinal end of the leaf spring is supported by the rotor case 28 via the lever 94, and the other longitudinal end of the lever 94 is separated from the rotor body 32 by the spreading force of the leaf spring 104. While being urged, the interference projection 100 provided at one end portion in the longitudinal direction of the lever 94 is engaged (contacted) with the outer peripheral portion of the rotor body 32 by the spreading force of the leaf spring 104.

  As shown in FIGS. 10 and 11, a guide groove 112 is formed on the outer peripheral portion of the rotor body 32. The guide groove 112 is formed at a position facing the lever 94, and an inclined path 114 formed along the circumferential direction of the rotor main body 32, and a convex part 116 that smoothly continues to one end of the inclined path 114, A curved path 118 provided on the opposite side of the inclined path 114 via the convex part 116, and one side in the axial direction of the rotor body 32 from the inclined path 114, the convex part 116, and the curved path 118 (in FIGS. 10 and 11). And a detour 120 having an entrance connected to the curved path 118 and an exit connected to the ramp 114. In FIGS. 10 and 11, for convenience of explanation, hatching and dots are given to each part of the guide groove 112.

  Here, as shown in FIG. 7, in a state where the rotor main body 32 is disposed at the LOCK position, the interference protrusion 100 of the lever 94 comes into contact with the inclined path 114. Further, in this state, the interference projection 100 interferes with the stepped portion 122 (see FIGS. 10 and 11) formed at the connection portion between the ramp 114 and the detour 120, so that the operation of pushing the rotor body 32 by the key 34 is performed. That is, the rotor main body 32 cannot be moved to the other side in the axial direction.

  Further, when the rotor body 32 is rotated from the LOCK position to the ACC position, the interference protrusion 100 slides on the inclined path 114 (see the arrow E in FIGS. 10 and 11), so that the interference protrusion 100, that is, the length of the lever 94 is increased. One end in the direction is moved radially outward of the rotor body 32 against the urging force of the leaf spring 104. As shown in FIG. 8, when the rotor body 32 reaches the ACC position, the interference protrusion 100 gets over the convex portion 116 and comes into contact with the curved path 118 (see the dashed line in FIG. 11). In this state, the rotation of the rotor body 32 to the LOCK position is restricted by the side surface 117 (see FIGS. 10 and 11) of the convex portion 116 interfering with the interference protrusion 100.

  However, in a state where the rotor main body 32 is disposed at the ACC position, the interference protrusion 100 faces the entrance of the detour 120. The detour 120 and the curved path 118 are smoothly continuous. In this state, the rotor body 32 can be pushed by the key 34. When the rotor main body 32 is pushed, the interference protrusion 100 is released from the interference with the convex portion 116 and enters the detour route 120 (see arrow F in FIG. 11). Since the exit of the bypass 120 is connected to the ramp 114, when the rotor body 32 is rotated to the LOCK position while being pushed in the ACC position, the interference protrusion 100 passes through the bypass 120 and the ramp 114. The rotor main body 32 is rotated to the LOCK position by being moved to the side (see arrow G in FIG. 11).

  On the other hand, as shown in FIG. 9, when the rotor main body 32 is disposed at the ON position and when the rotor main body 32 is disposed at the START position (not illustrated), the interference protrusion 100 contacts the curved path 118. In this state, it is separated from the convex portion 116. In this state, the interference projection 100 interferes with the wall portion 124 (see FIGS. 10 and 11) formed between the curved path 118 and the outer peripheral surface of the rotor body 32, so that the pushing operation of the rotor body 32 can be performed. It becomes the composition which disappears. In FIG. 11, the position of the interference protrusion 100 with respect to the rotor body 32 arranged at the ON position is indicated by a two-dot chain line, and the position of the interference protrusion 100 with respect to the rotor body 32 arranged at the START position is indicated by a dotted line. is there.

  On the other hand, between the cylinder accommodation hole 24 and the one fixed piece 14, one end side communicates with the cylinder accommodation hole 24, and the other end side communicates with the inside of a steering post (not shown). 5 is formed, and a lock bar 60 that is formed in a prismatic shape and constitutes a lock member is housed inside the lock bar housing hole 58. The lock bar 60 engages with a steering shaft (not shown) provided in the steering post to restrict the rotation of the steering shaft (a position shown in FIG. 2) and a release position (the release state where the engagement state is released). 4 (position shown in FIG. 4), and is always urged in the regulated position direction by the urging force of the torsion coil spring 62 provided in the lock bar accommodating hole 58. In the steering lock device 10, the movement direction of the lock bar 60 is set parallel to the axial direction of the rotor body 32.

  Further, a plate lock 64 constituting a lock member is provided between the lock bar 60 and the ignition cylinder 26. The plate lock 64 is formed in a long plate shape, and is disposed in a side of the ignition cylinder 26 and the camshaft 42 in a state parallel to the axis of the cylinder housing hole 24, and the longitudinal direction of the plate body 66. An L-shaped connecting portion 68 is integrally connected to one end portion in the direction (the end portion on the arrow B direction side in FIGS. 2 to 5). The connecting portion 68 is connected to the lock bar 60, and the plate lock 64 is always integrated with the lock bar 60 so as to move (slide) between the restriction position and the release position.

  A driven claw 70 is formed at one end in the longitudinal direction of the plate body 66 so as to face the inclined surface 46 of the camshaft 42 so as to come into contact therewith. The driven claw 70 slides on the inclined surface 46 when the camshaft 42 rotates together with the rotor body 32 from the LOCK position to the ACC position, and the plate lock 64 is moved in the release position direction by this sliding. A force directed in the direction of arrow A in FIG. 2 to FIG. 5 is applied and moved to the release position against the urging force of the torsion coil spring 62.

  When the camshaft 42 reaches the ACC position, as shown in FIG. 3, the driven claw 70 is hooked on one end of the camshaft 42 in the axial direction, so that the plate lock 64 and the lock bar 60 are held at the release position. The Even when the camshaft 42 is disposed at the ON position and the START position, the driven claw 70 is maintained in a state of being hooked on one end of the camshaft 42 in the axial direction, and the plate lock 64 and The lock bar 60 is held at the release position. Further, when the camshaft 42 rotates from the ACC position to the LOCK position together with the rotor body 32, the driven claw 70 is released from being caught on one end in the axial direction of the camshaft 42.

  On the other hand, the other end portion in the longitudinal direction of the plate body 66 (the end portion on the arrow A direction side in FIGS. 2 to 5) is disposed opposite and close to the outer peripheral portion of the rotor case 28, and the plate lock 64 is regulated. 2 (FIG. 2 and FIG. 5), the other end in the longitudinal direction of the plate body 66 is the outer periphery of the other end in the axial direction of the rotor case 28 (the arrow B direction in FIGS. 2 to 5). When the plate lock 64 is positioned at the release position (the state shown in FIGS. 3 and 4), the other end in the longitudinal direction of the plate body 66 is one end in the axial direction of the rotor case 28 (FIGS. 2 to 5). 5 is opposed to the outer periphery of the arrow A direction side).

  A lock piece 72 as an engaging portion is swingably attached to the other longitudinal end of the plate body 66, and the lock piece 72 has a restriction position and a release position together with the plate lock 64 and the lock bar 60. Move between. The lock piece 72 is formed to be sufficiently smaller than the plate lock 64.

  A locking projection 74 that protrudes toward the rotor case 28 is formed at the tip of the lock piece 72 (the end on the arrow A direction side in FIGS. 2 to 5). The lock piece 72 can swing between a first position (a position indicated by a solid line in FIG. 3) and a second position (a position indicated by a two-dot chain line in FIG. 3) with respect to the plate body 66. The first position is always biased by the biasing force of the torsion spring 76. The locking protrusion 74 approaches the outer periphery of the rotor case 28 when the lock piece 72 is disposed at the first position, and is separated from the outer periphery of the rotor case 28 when the lock piece 72 is disposed at the second position. It is supposed to be.

  A through hole 77 is formed on the outer peripheral portion of the rotor case 28 in the axial direction at a position facing the tip end portion of the lock piece 72 in a state where the lock piece 72 is disposed at the release position together with the plate lock 64. A second slide piece 78 serving as a movement blocking member is disposed in the through hole 77. The second slide piece 78 protrudes from the outer peripheral portion of the rotor case 28 and has a protruding position (position shown in FIGS. 2 to 4) disposed on the movement locus of the lock piece 72, and the distal end portion of the rotor case 28. Is retracted from the outer peripheral portion of the lock piece 72 and moved away from the movement locus of the lock piece 72 (position shown in FIG. 5) along the radial direction of the rotor case 28, and is not shown in the figure. The member (spring or the like) is always biased to the retracted position (rotor main body 32 side). An inclined surface 80 is formed at the tip of the second slide piece 78.

  Further, a first slide piece 82 is provided in the rotor body 32 at a position facing the second slide piece 78. The first slide piece 82 is supported so as to be movable in the radial direction with respect to the rotor body 32, and has an inclined surface 84. When the key 34 is inserted into the rotor main body 32 from the key insertion port 36, the first slide piece 82 is brought into contact with the inclined surface 84 so that the key 34 contacts the outer side in the radial direction of the rotor main body 32 (the rotor case 28 side). And the key 34 prevents the rotor body 32 from moving inward in the radial direction.

  Thus, in a state where the first slide piece 82 is moved to the rotor case 28 side, the second slide piece 78 is held by the first slide piece 82 at the above-described protruding position (on the movement locus of the lock piece 72). It has become so. Further, in a state where the key 34 is removed from the rotor main body 32, the first slide piece 82 can move inward in the radial direction of the rotor main body 32. Therefore, the second slide piece 78 is in the retracted position (the lock piece 72). (Outside the movement trajectory).

  Here, when the rotor body 32 is rotated from the LOCK position to the ACC position in a state where the second slide piece 78 is held in the protruding position, that is, in a state where the key 34 is inserted into the rotor body 32, the first slide piece 78 is rotated. The slide piece 82 rotates together with the rotor body 32 to the ACC position. In this state, the second slide piece 78 is held at the protruding position by engaging (contacting) the outer peripheral portion of the rotor body 32. Even when the rotor body 32 is rotated to the ON position or the START position, the second slide piece 78 is held at the removal preventing position by engaging with the outer peripheral portion of the rotor body 32.

  At this time, since the cam shaft 42 rotates together with the rotor body 32 to the ACC position, the lock bar 60, the plate lock 64, and the lock piece 72 slide from the restriction position to the release position. The locking projections 74 of the second slide piece 78 come into contact with (incline on) the inclined surface 80 of the second slide piece 78. Therefore, the lock piece 72 is moved to the second position (position indicated by a two-dot chain line in FIG. 3) against the urging force of the torsion spring 76 by sliding the locking projection 74 and the inclined surface 80, The locking projection 74 gets over the second slide piece 78.

  When the lock bar 60 reaches the release position, the lock piece 72 is moved to the first position (position indicated by the solid line in FIG. 3) by the urging force of the torsion spring 76, and the locking projection 74 is moved to the second slide piece 78. Engage (hook). Thus, the plate lock 64 and the lock bar 60 are connected to the ignition cylinder 26 via the lock piece 72 and the second slide piece 78, and the lock piece 72, the plate lock 64, and the lock bar 60 are attached to the torsion coil spring 62. It is held in the release position against the force.

  On the other hand, as shown in FIG. 4, when the rotor body 32 and the camshaft 42 are rotated from the ACC position to the LOCK position, the second slide piece 78 abuts against the first slide piece 82 again, and the first slide piece 82 It is held in the protruding position. For this reason, the locking projection 74 of the lock piece 72 is maintained in a state of being hooked on the second slide piece 78, and the lock piece 72, the plate lock 64, and the lock bar 60 are held in the release position.

  Further, as shown in FIG. 5, when the key 34 is pulled out from the rotor body 32, the movement of the first slide piece 82 by the key 34 is released, and the holding of the second slide piece 78 by the first slide piece 82 is released. Is done. For this reason, the second slide piece 78 is moved to the retracted position by a biasing force of a biasing member (not shown), and the catch of the locking projection 74 with respect to the second slide piece 78 is released. Therefore, the lock piece 72, the plate lock 64, and the lock bar 60 are slid to the restriction position by the urging force of the torsion coil spring 62, and the lock bar 60 is engaged with a steering shaft (not shown).

  Next, the operation of the first embodiment will be described.

  In the steering lock device 10 configured as described above, the rotor body 32 is disposed at the LOCK position when the key 34 is pulled out from the rotor body 32. In this state, the lock bar 60 is disposed at the restriction position and engaged with the steering shaft, and the rotation of the steering shaft is restricted.

  On the other hand, when the key 34 is inserted into the rotor body 32, the first slide piece 82 provided on the rotor body 32 is blocked by the key 34 from moving inward in the radial direction of the rotor body 32, and provided on the rotor case 28. The second slide piece 78 thus held is held in the protruding position by the first slide piece 82 (see FIG. 2).

  When the rotor body 32 is rotated from the LOCK position to the ACC position by the key 34, the first slide piece 82 rotates to the ACC position together with the rotor body 32. In this state, the second slide piece 78 is moved to the rotor body 32. It is held at the protruding position by engaging with the outer periphery of the.

  At this time, the cam shaft 42 is rotated together with the rotor body 32 from the LOCK position to the ACC position, and the inclined surface 46 of the cam shaft 42 and the driven claw 70 of the plate lock 64 slide. Therefore, a force directed toward the release position acts on the plate lock 64, and the plate lock 64 slides to the release position together with the lock bar 60 and the lock piece 72. 74 hits the inclined surface 80 of the second slide piece 78, and the lock piece 72 is moved to the second position (the position indicated by the two-dot chain line in FIG. 3) against the urging force of the torsion spring 76. The protrusion 74 gets over the second slide piece 78.

  When the lock bar 60 reaches the release position, the lock piece 72 is moved to the first position (position indicated by the solid line in FIG. 3) by the urging force of the torsion spring 76, and the locking projection 74 is moved to the second slide piece 78. Get caught. Accordingly, the lock piece 72, the plate lock 64, and the lock bar 60 are held at the release position against the urging force of the torsion coil spring 62 (see FIG. 3).

  Further, when the rotor body 32 and the camshaft 42 are rotated from the ACC position to the LOCK position, the second slide piece 78 is held at the protruding position by the first slide piece 82. For this reason, the latching protrusion 74 of the lock piece 72 is maintained in the state of being caught by the second slide piece 78, and the lock piece 72, the plate lock 64, and the lock bar 60 are maintained in the release position ( (See FIG. 4).

  On the other hand, when the key 34 is pulled out from the rotor main body 32, the movement prevention of the first slide piece 82 by the key 34 is released, and the holding of the second slide piece 78 by the first slide piece 82 is released. For this reason, the second slide piece 78 is moved to the retracted position by a biasing force of a biasing member (not shown), and the catch of the locking projection 74 with respect to the second slide piece 78 is released. Therefore, the lock piece 72, the plate lock 64, and the lock bar 60 are slid to the restriction position by the urging force of the torsion coil spring 62, and the lock bar 60 engages with a steering shaft (not shown). Thereby, rotation of a steering shaft is controlled (refer to Drawing 5).

  Here, in the steering lock device 10 according to the first embodiment, the plate lock 64 that moves (slides) together with the lock bar 60 as described above is connected to the ignition cylinder 26 via the lock piece 72 and the second slide piece 78. As a result, the lock bar 60 is held in the release position. Therefore, it is only necessary to secure a space for the plate lock 64 to slide inside the lock body 12 and a space for the rock piece 72 that is sufficiently smaller than the plate lock 64 to swing. Unlike the conventional steering lock device described above, it is not necessary to secure a space for oscillating the long locking lever in the device (lock body), and thus the device can be miniaturized.

  Further, in the conventional steering lock device described in the background art section, the locking lever is supported so as to be swingable by, for example, a support shaft attached to the lock body by caulking or the like. In the steering lock device 10 according to the embodiment, since the caulking process as described above is unnecessary, the manufacturing process can be simplified and the manufacturing cost can be reduced.

  Furthermore, in the steering lock device 10 according to the first embodiment, the plate lock 64 is moved along the axial direction of the ignition cylinder 26 (rotor main body 32) together with the lock bar 60. Therefore, the movement space of the plate lock 64 does not unnecessarily expand in the radial direction of the ignition cylinder 26, and the external dimensions of the device (lock body 12) along the radial direction of the ignition cylinder 26 can thereby be reduced.

  Furthermore, in the steering lock device 10 according to the first embodiment, the lock piece 72 attached to the plate lock 64 so as to be swingable and biased to the first position (direction approaching the ignition cylinder 26) is provided. The second slide piece 78 is moved to the second position (in the direction away from the ignition cylinder 26) by hitting the inclined surface 80 of the second slide piece 78, and the second slide piece 78 is overcome. Therefore, in a state where the key 34 is inserted into the rotor main body 32, the second slide piece 78 can always be held at the protruding position, so that the holding mechanism for the second slide piece 78 (the first slide piece 82, the rotor) The outer peripheral portion of the main body 32 can be configured simply.

  In the steering lock device 10 according to the first embodiment, a camshaft 42 is coaxially connected to the rotor body 32 that is rotated by the key 34 on the opposite side to the insertion port 36 of the key 34. ing. For this reason, the installation space of the camshaft 42 is not unnecessarily enlarged in the radial direction of the rotor body 32.

  In addition, a plate lock 64 for connecting the lock bar 60 and the ignition cylinder 26 is disposed on the side in the radial direction of the camshaft 42 coaxially connected to the rotor body 32 and is applied from the camshaft 42. This is a configuration in which the lock bar 60 is moved from the restricting position to the release position together with the locking force. That is, the single plate lock 64 moved along the axial direction of the ignition cylinder 26 is used for both the connection between the lock bar 60 and the ignition cylinder 26 and the transmission of the force from the cam shaft 42 to the lock bar 60. Since it has a function, it is possible to suppress an increase in the number of parts and to suppress an increase in the installation space for the parts.

  In the steering lock device 10 according to the first embodiment, the lock piece 72 (engagement portion) that is swingably attached to the plate lock 64 is caught by the second slide piece 78 (movement preventing member). Thus, the lock bar 60 and the ignition cylinder 26 are connected to each other. However, the present invention is not limited to this, and an elastic member (for example, a leaf spring) provided as an engagement portion provided in the plate lock 64 is used as the second slide. The lock bar 60 and the ignition cylinder 26 may be connected by being hooked on the piece 78. In this case, the elastic member may be formed integrally with the plate lock 64, or may be formed separately and attached to the plate lock 64.

  In the steering lock device 10 according to the first embodiment, the second slide piece 78 is held at the protruding position (on the movement locus of the lock piece 72) in a state where the key 34 is inserted into the rotor body 32. In the state where the key 34 is pulled out from the rotor main body 32, the second slide piece 78 is retracted to the retracted position (outside the movement locus of the lock piece 72). In the state where the second slide piece 78 is inserted into the rotor case 28 and the key 34 is pulled out from the rotor body 32, the second slide piece 78 is moved radially outward of the rotor body 32. It is good also as a structure to be. In this case, for example, when the lock bar 60 is moved to the release position, the locking projection 74 of the lock piece 72 is caught in the through hole 77 of the rotor case 28, and the second slide piece 78 is moved in the radial direction of the rotor body 32. What is necessary is just to set it as the structure by which the catch with respect to the through-hole 77 of the latching protrusion 74 is cancelled | released by moving outside.

  Furthermore, in the steering lock device 10 according to the first embodiment, the lock bar 60 and the plate lock 64 constituting the lock member are separately formed and connected. However, the present invention is not limited to this. The bar 60 and the plate lock 64 may be integrally formed.

Further, in the steering lock device 10 according to the first embodiment, the lock bar 60 is moved along the axial direction of the rotor main body 32 together with the plate lock 64. The plate lock 64 may be moved along the radial direction of the rotor body 32. However, even in this case, the lock bar 60 and the plate lock 64 need to be arranged so that the locking projection 74 of the lock piece 72 faces the second slide piece 78 when the lock bar 60 is moved to the release position. is there.
<Second Embodiment>
Next, a second embodiment of the present invention will be described. Note that configurations and operations that are basically the same as those in the first embodiment are given the same reference numerals as in the first embodiment, and descriptions thereof are omitted.

  12 to 17 are sectional views showing the configuration of the steering lock device 150 according to the second embodiment of the present invention. In FIGS. 12 to 17, for convenience of explanation, some members are not hatched, and the ignition switch 54 and the lever 94 are not shown.

  The steering lock device 150 has basically the same configuration as the steering lock device 10 according to the first embodiment, but differs in the following points.

  The plate lock 152 of the steering lock device 150 has basically the same configuration as the plate lock 64 according to the first embodiment, but the ignition cylinder 26 is disposed at the other longitudinal end of the plate body 154. An engaging portion 156 that protrudes to the side is formed, and the lock piece 72 and the torsion spring 76 according to the first embodiment are omitted.

  The second slide piece 158 of the steering lock device 150 has basically the same configuration as the second slide piece 78 according to the first embodiment, but the second slide piece 158 includes As shown in FIG. 18A, an intrusion portion 160 that protrudes toward the first slide piece 82 and contacts the first slide piece 82 is provided, and the inclined surface 80 according to the first embodiment is omitted. It has been configured.

  Here, the steering lock device 150 is configured such that the second slide piece 158 is disposed at the protruding position when the intrusion portion 160 is in contact with the first slide piece 82. In addition, in a state where the second slide piece 158 is disposed at the protruding position, the distal end portion (the end portion opposite to the intrusion portion 160) of the second slide piece 158 is disposed on the movement locus of the engagement portion 156. When the plate lock 152 is moved to the release position together with the lock bar 60 and the second slide piece 158 is held at the protruding position, the engaging portion 156 engages with the distal end portion of the second slide piece 158. (To be caught). Accordingly, the plate lock 152 and the lock bar 60 are held at the release position.

  Further, in a state where the second slide piece 158 is disposed at the retracted position, the distal end portion of the second slide piece 158 is configured to retract out of the movement locus of the engaging portion 156. For this reason, when the engaging portion 156 is hooked on the second slide piece 158 as described above and the second slide piece 158 is moved to the retracted position while the plate lock 152 and the lock bar 60 are held at the release position, The engagement between the engaging portion 156 and the second slide piece 158 is released, and the plate lock 152 is moved together with the lock bar 60 to the restricted position by the urging force of the torsion coil spring 62.

  On the other hand, the rotor main body 162 of the steering lock device 150 has basically the same configuration as the rotor main body 32 according to the first embodiment, but as shown in FIGS. 19 and 20, the rotor main body 162. A recess 164 is formed on the outer peripheral portion at one end in the axial direction. In FIG. 19 and FIG. 20, for convenience of explanation, dots are given to the surface of the first slide piece 82.

  The concave portion 164 has an elongated shape along the circumferential direction of the rotor body 162, and a part of the concave portion 164 is configured by cutting out a part of the first slide piece 82. In addition, inclined surfaces 166 and 168 are formed at both ends of the recess 164 along the circumferential direction of the rotor main body 162. The recess 164 is disposed so as to face the intrusion portion 160 of the second slide piece 158 while the rotor main body 162 is rotated from the LOCK position to the ACC position. The intrusion portion 160 can enter the recess 164. Has been.

  Here, in the steering lock device 150, the second slide piece 158 is urged toward the rotor main body 162 by an urging member (not shown) as in the first embodiment, so that the rotor main body 162 is locked. When rotating from the position to the ACC position, the intrusion portion 160 enters the recess 164 through the inclined surface 166 during the rotation (see arrow J in FIGS. 19 and 20), and the second slide piece 158 is moved. It is moved to the retracted position (see FIG. 18B).

  At this time, since the lock bar 60 and the plate lock 152 are moved to the release position, the engaging portion 156 approaches the second slide piece 158, but the second slide piece 158 is moved to the retracted position as described above. Thus, the engagement (collision) between the engaging portion 156 and the second slide piece 158 is avoided (see FIG. 13).

  When the rotor body 162 is rotated to the vicinity of the ACC position (in the second embodiment, when the rotor body 162 is rotated 45 degrees from the LOCK position), the lock bar 60 and the plate lock 152 are released. As the position reaches the position, the intrusion portion 160 comes into contact with the inclined surface 168 (see FIG. 18B). When the rotor body 162 is further rotated toward the ACC position from this state, the second slide piece 158 receives a force directed toward the protruding position by the sliding of the intrusion portion 160 and the inclined surface 168. It has become. As a result, the intrusion portion 160 comes out of the recess 164 (see the arrow K in FIGS. 19 and 20), and the second slide piece 158 is moved to the protruding position.

  Further, as shown in FIG. 18C, in the state where the rotor body 162 has reached the ACC position (in the second embodiment, the rotor body 162 is rotated 55 degrees from the LOCK position), the second The slide piece 158 is held at the protruding position by the intrusion portion 160 coming into contact with the outer peripheral portion (holding surface 170) of the rotor body 162. For this reason, as shown in FIG. 14, the engaging part 156 moved to the release position is caught by the second slide piece 158, and the lock bar 60 and the plate lock 152 are held at the release position.

  In FIG. 19 and FIG. 20, for convenience of explanation, a region (holding surface 170) where the intrusion portion 160 contacts is hatched in the outer peripheral portion of the rotor body 162. In FIG. 20, the position of the intrusion portion with respect to the rotor main body 162 arranged at the LOCK position is indicated by a one-dot chain line, and the position of the intrusion portion 160 with respect to the rotor main body 162 arranged at the ACC position is indicated by a dotted line. Further, in the steering lock device 150, even when the rotor main body 162 is disposed at the ON position and the START position, the second slide piece 158 has the intrusion portion 160 in contact with the outer peripheral portion (the holding surface 170) of the rotor main body 162. Thus, it is held at the protruding position. Therefore, even in this state, the lock bar 60 and the plate lock 152 are held in the release position.

  On the other hand, when the rotor main body 162 is rotated from the ACC position to the LOCK position, the rotor main body 162 is pushed at the ACC position as in the steering lock device 10 according to the first embodiment. However, when the rotor body 162 is pushed in this way, the rotor body 162 moves relative to the second slide piece 158 in the axial direction as shown in FIG. 164 is displaced in the axial direction of the rotor body 162 with respect to 164 (see arrow L in FIGS. 19 and 20). Even in this state, the second slide piece 158 is held at the protruding position by the intrusion portion 160 coming into contact with the outer peripheral portion (holding surface 170) of the rotor body 162. Therefore, even in this state, the lock bar 60 and the plate lock 152 are held in the release position.

  Further, even when the rotor body 162 that has been pushed in at the ACC position is rotated to the LOCK position, the second slide piece 158 causes the intrusion portion 160 to slide with the outer peripheral portion of the rotor body 162 (FIG. 19). And the arrow M in FIG. 20). Therefore, even in this state, the lock bar 60 and the plate lock 152 are held in the release position.

  When the rotor main body 162 reaches the LOCK position and the pushing operation is released, the rotor main body 162 moves toward one end in the axial direction of the cylinder housing hole 24 by the biasing force of the torsion coil spring 52 as shown in FIG. Then, the intrusion portion 160 of the second slide piece 158 comes into contact with the first slide piece 82. Accordingly, the second slide piece 158 is held in the protruding position by the first slide piece 82, and the lock bar 60 and the plate lock 152 are maintained in the release position.

  On the other hand, when the key 34 is pulled out from the rotor main body 162 arranged at the LOCK position, the first slide piece 82 can move inward in the radial direction of the rotor main body 162, whereby the second slide piece by the first slide piece 82 is obtained. The holding of 158 is released, and the second slide piece 158 is moved to the retracted position by a biasing force of a biasing member (not shown). As a result, the engagement of the engaging portion 156 with respect to the second slide piece 158 is released, and the lock bar 60 and the plate lock 152 are moved to the restriction position by the urging force of the torsion coil spring 62, as shown in FIG.

  In the steering lock device 150, other components are basically the same as those of the steering lock device 10 according to the first embodiment.

  Next, the operation of the second embodiment will be described.

  In the steering lock device 150 configured as described above, the rotor body 162 is disposed at the LOCK position when the key 34 is pulled out from the rotor body 162. In this state, the lock bar 60 is disposed at the restriction position and engaged with the steering shaft, and the rotation of the steering shaft is restricted.

  On the other hand, when the key 34 is inserted into the rotor body 162, the first slide piece 82 provided on the rotor body 162 is blocked by the key 34 from moving inward in the radial direction of the rotor body 162, and provided on the rotor case 28. The second slide piece 158 thus held is held in the protruding position by the first slide piece 82 (see FIG. 12).

  When the rotor body 162 is rotated from the LOCK position to the ACC position by the key 34, the first slide piece 82 is rotated together with the rotor body 162 to the ACC position, and the intruding portion 160 of the second slide piece 158 is moved to the rotor body 162. It enters into the recess 164. Thereby, the second slide piece 158 is moved to the retracted position.

  At this time, the camshaft 42 is rotated together with the rotor body 162 from the LOCK position to the ACC position, and the inclined surface 46 of the camshaft 42 and the driven claw 70 of the plate lock 152 slide. Therefore, a force directed toward the release position acts on the plate lock 152, and the plate lock 152 slides to the release position together with the lock bar 60. However, as described above, the second slide piece 158 is moved to the retracted position. Therefore, it is avoided that the engaging portion 156 of the plate lock 152 collides with the second slide piece 158 (see FIG. 13).

  When the rotor main body 162 is rotated to the vicinity of the ACC position (in this embodiment, when the rotor main body 162 is rotated 45 degrees from the LOCK position), the lock bar 60 and the plate lock 152 reach the release position. At the same time, the intrusion portion 160 hits the inclined surface 168. When the rotor body 162 is further rotated toward the ACC position from this state, the intrusion portion 160 slides on the inclined surface 168, the intrusion portion 160 comes out of the recess 164, and the second slide piece 158 is moved to the projecting position. The

  Further, in a state where the rotor main body 162 has reached the ACC position (in this embodiment, the rotor main body 162 is rotated 55 degrees from the LOCK position), the second slide piece 158 has the intrusion portion 160 of the rotor main body 162. By contacting the outer peripheral portion (holding surface 170), it is held at the protruding position. For this reason, the engaging part 156 moved to the release position is caught by the second slide piece 158, and the lock bar 60 and the plate lock 152 are held at the release position (see FIG. 14).

  On the other hand, when the rotor body 162 is pushed in at the ACC position, the rotor body 162 moves relative to the second slide piece 158 in the axial direction as shown in FIG. Thus, the rotor body 162 is displaced in the axial direction (see FIG. 15). Even in this state, the second slide piece 158 is held at the protruding position by the intrusion portion 160 coming into contact with the outer peripheral portion (holding surface 170) of the rotor body 162, and the lock bar 60 and the plate lock 152 are held at the release position. Maintained.

  Further, when the rotor main body 162 that has been pushed in at the ACC position is rotated to the LOCK position, the second slide piece 158 causes the intrusion portion 160 to slide with the outer peripheral portion (holding surface 170) of the rotor main body 162. The state held in the protruding position is maintained, and the lock bar 60 and the plate lock 152 are maintained in the released position.

  When the rotor main body 162 reaches the LOCK position and the pushing operation is released, the rotor main body 162 moves to one end side in the axial direction of the cylinder accommodation hole 24 by the urging force of the torsion coil spring 52, and the second slide piece 158. The intruding portion 160 contacts the first slide piece 82 (see FIG. 16). Accordingly, the second slide piece 158 is held in the protruding position by the first slide piece 82, and the lock bar 60 and the plate lock 152 are maintained in the release position.

  On the other hand, when the key 34 is pulled out from the rotor main body 162 arranged at the LOCK position, the first slide piece 82 can be moved inward in the radial direction of the rotor main body 162, and thus the second slide piece 158 by the first slide piece 82. Is released, and the second slide piece 158 is moved to the retracted position by a biasing force of a biasing member (not shown). As a result, the engagement of the engaging portion 156 with respect to the second slide piece 158 is released, and the lock bar 60 and the plate lock 152 are moved to the restriction position by the biasing force of the torsion coil spring 62 (see FIG. 17).

  The steering lock device 150 having the above configuration also has basically the same operations and effects as the steering lock device 10 according to the first embodiment. In addition, since the steering lock device 150 has a configuration in which the lock piece 72 according to the first embodiment is omitted, the device can be further downsized.
