Description

Technical Field

[0001] This invention relates to a handle locking device. Background Technology

[0002] The handle locking device disclosed in Patent Document 1 can switch between a locked state where the handle cannot be turned via the steering shaft, an on state where the vehicle's engine can be started, and an off state where the handle can be turned but the engine cannot be started. These state switching is performed by turning a mechanical key inserted into the keyhole to the locked position, the on position, and the off position.

[0003] Patent Document 1's handle locking device includes, within a housing: a lock cylinder, including a keyhole for inserting a mechanical key; a connector for moving the locking member forward and backward; and a contact bracket for switching the vehicle's power supply state. The lock cylinder and connector are designed to be non-rotatable relative to each other, and the connector and contact bracket are also designed to be non-rotatable relative to each other. Thus, by rotating the mechanical key (the operated member) including the lock cylinder, the connector and contact bracket are rotated integrally.

[0004] Patent Document 1's handle locking device includes a force-applying member that applies force to the locking member in a non-engaged position within the housing, so as to prevent the handle from locking during operation. Furthermore, the handle locking device includes a positioning mechanism that positions the connector and contact bracket, including the operated member, in a locked position, an engaged position, and a disengaged position. The positioning mechanism includes a spring and a ball disposed on the contact bracket, and a recess into which the ball can be inserted. The resistance generated between the ball and the recess by the applied force of the spring, i.e., the resistance to inhibiting the rotation of the contact bracket, is greater than the applied force of the force-applying member of the locking member. Therefore, in the non-operating state of the operated member, rotation inhibition of the contact bracket, including the connector, is achieved.

[0007] Patent Document 1: Japanese Patent No. 4979656 Summary of the Invention

[0008] The problem that the invention aims to solve

[0009] In the handle locking device of Patent Document 1, the contact bracket rotates integrally with the operated component, thus wear of the positioning mechanism (e.g., the recess) is unavoidable. When the resistance generated by the positioning mechanism due to wear is less than the applied force of the force-applying component, the contact bracket, including the joint, can rotate simply by the user contacting the operated component. Therefore, when in contact with the operated component in the locked state, the handle locking device may become accidentally unlocked, thus there is room for improvement in the anti-theft performance of the handle locking device in Patent Document 1.

[0010] The technical problem of this invention is to prevent accidental unlocking of the handle locking device, thereby improving the vehicle's anti-theft capability.

[0011] Solution for solving the problem

[0012] The present invention provides a handle locking device comprising: a rotatable operated member; a connector that rotates coaxially and integrally with the operated member; a contact bracket that rotates coaxially and integrally with the connector; a positioning part that positions the contact bracket when the operated member is rotated to at least a locked position; a locking member that is movable between an engaged position in which the handle engages with a steering shaft to lock the vehicle and a non-engaged position in which the handle is disengaged from the steering shaft to release the lock, and is moved to the engaged position by rotation of the connector achieved by rotation of the operated member toward the locked position; and a force-applying member that applies force to the locking member toward the non-engaged position. In the handle locking device, a rotation limiting part is provided between the connector and the locking member, the rotation limiting part limiting the rotation of the connector when the operated member is in the locked position.

[0013] A rotation limiting part is provided between the connector and the locking member, which restricts the rotation of the connector when the operated member is in the locked position. Therefore, regardless of the wear condition of the positioning part, even if the user touches the operated member when the handle locking device is in the locked state, the rotation limiting part can restrict the rotation of the connector. As a result, the locking member can be maintained in the engaged position by the connector, thus preventing accidental unlocking of the handle locking device and improving vehicle anti-theft capabilities.

[0015] In this invention, accidental unlocking of the handle locking device can be suppressed, thereby improving the vehicle's anti-theft capability. Attached Figure Description

[0040] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0041] (First Implementation)

[0042] Reference Figure 1 The handle locking device 20 of the first embodiment of the present invention is installed in vehicle 1 and can be in the unlocked state that allows the handle 3 to be turned (see reference). Figure 3 ) and the locked state of the steering limit handle 3 (refer to Figure 5 The vehicle 1 in this embodiment is a bicycle (two-wheeled vehicle) with a prime mover. Vehicle 1 can be an automatic two-wheeled vehicle, a four-wheeled car, or other types of vehicles.

[0043] In the attached diagram, the X direction represents the length of vehicle 1, the direction indicated by the arrow is the front, and the opposite direction is the rear. The Y direction represents the width of vehicle 1, and the Z direction represents the height of vehicle 1.

[0044] Reference Figure 1 and Figure 3 The handle locking device 20 includes a switching mechanism 25 and a limiting mechanism 50 mounted on the housing 22. The switching mechanism 25 includes an operating knob 26, a connector 27, a rotary switch 30, a locking member 38, a cover rod 43, and a seat rod 45. The limiting mechanism 50 includes a solenoid 51 and a limiting rod 52, which, as in the past, limits the rotation of the operating knob 26.

[0045] First, refer to Figure 1 An overview of the vehicle 1 equipped with the handle locking device 20 is provided.

[0046] Vehicle 1 is equipped with a smart locking system. Vehicle 1 includes a steering shaft 2, handle 3, cover 4, seat 5, ECU (Electronic Control Unit) 6, authentication unit 7, transceiver unit 8, engine 9, and a separate, dedicated (official) electronic key 15. The electronic key 15 includes a control unit 16 and a transceiver unit 17.

[0047] The steering shaft 2 is rotatably mounted to the vehicle body frame (not shown). The handle 3 is fixed so that it cannot move relative to the steering shaft 2. A handle locking device 20 is bolted to the portion of the vehicle body frame that supports the steering shaft 2. Rotating the operating knob 26 of the handle locking device 20 engages the locking member 38, locking it into the steering shaft 2 and preventing rotation (see reference). Figure 5 On the other hand, by rotating the knob 26, the locking member 38 is released from engagement with the steering shaft 2, thereby releasing the lock on the handle 3 (see reference). Figure 3 ).

[0048] Cover 4 is a structure used to close the gasoline receiving section (not shown) in vehicle 1 in an openable manner. The receiving section can be a structure that receives liquid fuels such as light oil, a structure that receives gaseous fuels such as hydrogen and LP gas, or a structure that receives electricity. Cover 4 is opened by operating the cover lever 43 by operating the operating knob 26 of the handle locking device 20. Cover 4 is closed by a direct closing operation performed by the user.

[0049] Seat 5 is a structure for a user to sit on while the vehicle 1 is in motion. Seat 5 also functions to close a compartment (not shown) of the vehicle 1 in an openable manner. Seat 5 is opened by operating the knob 26 of the handle locking device 20, which activates the seat lever 45. Seat 5 is closed by a direct closing operation performed by the user.

[0050] Based on the detection status of the legitimate electronic key 15 by the authentication unit 7, the ECU (control unit) 6 activates the limiting mechanism 50 of the handle locking device 20, switching the operation knob 26 between an inoperable restricted state and an operable restricted released state. Within a defined detection area around the vehicle 1, the authentication unit 7 wirelessly communicates between the transceiver unit 8 and the transceiver unit 17 of the electronic key 15, and performs key authentication. If the stored legitimate code matches the authentication code received from the electronic key 15, and key authentication is successful, the authentication unit 7 determines that a legitimate electronic key 15 exists within the detection area. Conversely, if the authentication code cannot be received from the electronic key 15, or if the stored legitimate code does not match the authentication code received from the electronic key 15 and key authentication fails, the authentication unit 7 determines that a legitimate electronic key 15 does not exist within the detection area.

[0051] When key authentication is successful, ECU6 activates the solenoid 51 of the limiting mechanism 50, releasing the restriction of the limiting lever 52 on the operating knob 26, allowing the operating knob 26 to rotate (see reference). Figure 3 On the other hand, when the engine 9 stops and key authentication fails, the ECU 6 activates the solenoid 51 of the limiting mechanism 50, thereby limiting the rotation of the operating knob 26 via the limiting rod 52 (see reference). Figure 5 For example, when a user carrying the valid electronic key 15 leaves the vehicle 1 and becomes unable to communicate wirelessly, the key authentication changes from an established state to an invalid state. The ECU 6 can also be structured such that it not only authenticates the key but also detects the operation of the operating knob 26 (e.g., pressing) via a switch (not shown) to activate the limiting mechanism 50.

[0052] Next, the structure of the switching mechanism 25 of the handle locking device 20 will be described in detail.

[0053] Reference Figures 1 to 3 The operating knob 26, connector 27, and rotary switch 30 of the switching mechanism 25 are arranged in series from the rear to the front in the vehicle length direction within the housing 22. The locking member 38, cover rod 43, and seat rod 45 are located in the middle part of the connector 27.

[0054] Combination Figure 2 And refer to Figure 3 The operating knob 26 is an operated component that is installed on the rear side of the housing 22 in the vehicle length direction and is exposed externally to allow operation by the user. When viewed in the vehicle length direction, the operating knob 26 has a cylindrical knob body 26a and a plate-shaped handle 26b that protrudes from the knob body 26a in the vehicle length direction and extends radially.

[0055] In this embodiment, the operating knob 26 can be switched in four ways via the connector 27 through user operation. The first way is to rotate the rotary switch 30 to turn the engine 9 (see reference). Figure 1 The first method switches between an energized state (capable of starting) and a de-energized state (unable to start). The second method is to keep the locking member 38 in a non-engaged position (see reference). Figure 3 ) and engagement position (refer to) Figure 5 The third method involves moving the handle 3 between the unlocked and locked states. The handle 43 is rotated to open the cover 4 (see reference). Figure 1 The fourth method involves rotating the seat lever 45 to switch the seat 5 (refer to...) from the closed state to the open state. Figure 1 The control knob 26 is installed so that it can move forward and backward and rotate with respect to the housing 22 and the connector 27.

[0056] Specifically, the operating knob 26 is mounted relative to the housing 22 in a non-pressed position (see reference). Figure 3 ) and pressing position (refer to Figure 4 The knob 26 moves along the axis (rotation axis) A extending in the length direction of the vehicle. The operating knob 26 is forced to the non-pressed position by the coil spring 28 via the connector 27.

[0057] like Figure 2 As most clearly shown, the operating knob 26 is mounted so that it can rotate about axis A relative to the housing 22, between the engaged position 22b and the locked position 22c, through the disengaged position (initial position) 22a and the seated position 22e. In this embodiment, it will be used to open the cover 4 (see reference 4). Figure 1 The cover position 22d is set to the same rotation angle as the on position 22b. However, the cover position 22d can also be set to a different rotation angle than the on position 22b.

[0058] The four switching operations performed by the operating knob 26 are set as follows. In the on / off operation of switching the rotary switch 30 to its energized state, without pressing the operating knob 26 (see...), Figure 3 The operating knob 26 is rotated by means of the pinch handle 26b being in the engaged position 22b and not in the engaged position 22b. During locking and unlocking operations, when switching the engagement state of the locking member 38, the operating knob 26 is pressed (see...). Figure 4 The operating knob 26 is rotated with the handle 26b in the locked position 22c and out of the locked position 22c. During the operation of switching the cover 4 to the open state, the operating knob 26 is pressed (see...). Figure 4The operating knob 26 is rotated by pinching the handle 26b on the cover position 22d. During the operation of switching the seat 5 to the open position, without pressing the operating knob 26 (see...). Figure 3 The operating knob 26 is rotated by pinching the handle 26b in the seat position 22e.

[0059] Reference Figures 3 to 5 The connector 27 is a transmission member used to transmit the operating force of the operating knob 26 to any one of the rotary switch 30, locking member 38, cover rod 43 and seat rod 45 according to the switching operation of the operating knob 26.

[0060] The connector 27 is mounted so that it cannot move relative to the operating knob 26, and is mounted so that it can move forward and backward along axis A and rotate about axis A relative to the housing 22. Thus, the connector 27 can be moved from the non-pressed position (see reference 26) by pressing the operating knob 26. Figure 3 Move to the pressing position (refer to) Figure 4 It can be rotated by operating the knob 26. The connector 27 is moved to the non-pressed position by the coil spring 28 (see reference). Figure 3 Apply force. The top end of the coil spring 28 is locked to the housing 22, and the rear end of the coil spring 28 is locked to the connector 27.

[0061] Reference Figures 6 to 9 The connector 27 has a rod-shaped main portion 27a extending along the length of the vehicle. The main portion 27a extends from the rear to the front along the length of the vehicle in the sequence of locking member 38, seat rod 45, and cover rod 43. At the rear end of the main portion 27a in the length direction, a supported portion 27b is provided, protruding radially outward about axis A. This supported portion 27b is supported by the housing 22 and is rotatable. An operating knob 26 is installed in the supported portion 27b, and the rear end of a coil spring 28 is engaged therein. A limiting bearing portion 27c is provided on the outer periphery of the supported portion 27b, recessed radially inward. This limiting bearing portion 27c limits the rotation of the connector 27 by engaging a limiting rod 52.

[0062] A locking arm 27d and a recess 27e are provided in the main part 27a at positions corresponding to the locking member 38. A pair of engaging protrusions 27f are provided at the top of the main part 27a corresponding to the rotary switch 30. A pair of operating protrusions 27g are provided in the main part 27a at positions corresponding to the cover rod 43 and the seat rod 45. The locking arm 27d, the engaging protrusions 27f, and the operating protrusions 27g will be described in detail later.

[0063] Reference Figure 1 and Figure 3A rotary switch 30 is mounted at the top of the housing 22 along its length. The rotary switch 30 detects the on / off operation of the operating knob 26 via a connector 27 and outputs the corresponding signal to the ECU 6 via a lead (not shown). Thus, the ECU 6 controls the onboard equipment, including the engine 9.

[0064] The rotary switch 30 includes a contact base 31 and a contact bracket 32. The contact base 31 has a fixed terminal (not shown) that is fixed to the housing 22 by bolts. The contact bracket 32 ​​has a movable terminal (not shown) that can contact the fixed terminal and is rotatably mounted on the rear side of the contact base 31 in the vehicle length direction.

[0065] Reference Figure 3 , Figure 4 as well as Figure 8 The contact bracket 32 ​​can be switched to an engaged state, rotating in conjunction with the rotation of the connector 27, by not pressing the operating knob 26, and to a non-engaged state, rotating independently of the connector 27, by pressing the operating knob 26. The connector 27 has a pair of engaging protrusions 27f protruding radially outward from the main portion 27a. At the rear end of the contact bracket 32 ​​in the vehicle length direction, there is an engaging recess 32a corresponding to the engaging protrusions 27f. The engaging recess 32a is formed by a through hole in a roughly "+" shape extending in the vehicle length direction.

[0066] like Figure 3 As shown, when the connector 27 is in the non-pressed position, the engaging protrusion 27f is positioned relative to the engaging recess 32a in the length direction of the vehicle. Therefore, the engaging protrusion 27f can engage with the engaging recess 32a, and thus, when the operating knob 26 is rotated, the contact bracket 32 ​​rotates integrally via the connector 27. On the other hand, as... Figure 4 As shown, when the connector 27 is moved to the pressing position, the engaging protrusion 27f is positioned forward in the vehicle length direction, spaced apart from the engaging recess 32a. That is, the engagement between the engaging recess 32a and the engaging protrusion 27f is released. Therefore, the engaging protrusion 27f cannot engage with the engaging recess 32a, and thus even if the operating knob 26 is rotated, the contact bracket 32 ​​will not rotate integrally via the connector 27, but rather relative rotation of the connector 27 is permitted.

[0067] like Figure 8 As shown, the engaging recess 32a has a pair of first recesses 32b and second recesses 32c that are radially opposed to each other.

[0068] Turn the operating knob 26 to the off position 22a (see reference) Figure 2 When in the non-pressing position (refer to...) Figure 3The connector 27 has a pair of engaging protrusions 27f engaging with a pair of first recesses 32b. Between the circumferential wall of the first recesses 32b and the engaging protrusions 27f, the smallest possible gap is ensured without hindering their engagement and disengagement.

[0069] Turn the operating knob 26 to the locked position 22c (see reference) Figure 2 When pressing, from the pressing position (refer to...) Figure 4 Move to a non-pressing position (see reference) Figure 3 The connector 27 has a pair of engaging protrusions 27f engaging with a pair of second recesses 32c.

[0070] Combination Figure 2 And refer to Figure 3 and Figure 5 A positioning mechanism (positioning part) 33 is provided between the contact bracket 32 ​​and the housing 22. The positioning mechanism 33 is a structure used to position the contact bracket 32 ​​in a way that prevents it from rotating when the operating knob 26 is rotated to the off position 22a, the on position 22b, and the locked position 22c. The positioning mechanism 33 consists of a coil spring 34 and a ball bearing 35, and a positioning recess 36. However, the positioning mechanism 33 may also be composed of a fixed terminal provided by the contact base 31 and a movable terminal provided by the contact bracket 32.

[0071] The coil spring 34 and the ball bearing 35 are respectively disposed in recesses located at radially opposite positions on the contact bracket 32. A positioning recess 36 is formed in the housing 22 and is constituted by a V-shaped groove extending along the length of the vehicle. The positioning recesses 36 are respectively provided at positions corresponding to the ball bearing 35 when the operating knob 26 is rotated to the off position 22a and the on position 22b. As described above, the contact bracket 32 ​​does not rotate during the locking and unlocking operations of the operating knob 26. Therefore, the positioning recess 36 that positions the operating knob 26 in the locked position 22c is shared with the positioning recess 36 that positions the operating knob 26 in the off position 22a.

[0072] Continue to combine Figure 2 And refer to Figure 3 and Figure 5 The locking member 38 can move forward and backward relative to the housing 22 in the vehicle width direction in conjunction with the rotation of the connector 27, which is achieved by the locking and unlocking operation of the operating knob 26. The locking member 38 consists of a cylindrical locking pin 39 and a slider 40 to which the locking pin 39 is fixed.

[0073] The locking pin 39 can be inserted into the insertion hole 22f of the housing 22. This is achieved by placing the operating knob 26 in the pressed state (see reference). Figure 4 From the disengaged position 22a to the locked position 22c, the locking pin 39 advances relative to the housing 22 via the connector 27 and the slider 40 to the engaged position on the outer side in the vehicle width direction (see reference). Figure 5 Thus, the locking pin 39 is engaged in the locking recess 2a of the steering shaft 2 (see reference). Figure 5 ), Lock handle 3 (refer to) Figure 1 On the other hand, by keeping the operation knob 26 in the pressed state (see...) Figure 4 From the locked position 22c to the unlocked position 22a, the locking pin 39, relative to the housing 22, is inserted into the non-engaged position in the vehicle width direction via the connector 27 and the slider 40 (see reference). Figure 3 Therefore, the locking pin 39 disengages from the locking recess 2a of the steering shaft 2 (see reference). Figure 3 Release handle 3 (refer to) Figure 1 ) lock.

[0074] Reference Figures 8 to 10 The locking pin 39 has a flange-shaped mounting portion 39a and a support portion 39b on the base end side opposite to the top end embedded in the steering shaft 2. The mounting portion 39a is for mounting to the slider 40. The support portion 39b is for supporting the non-engaged position (see reference). Figure 3 The structure of one end of the coil spring (force-applying component) 41. The other end of the coil spring 41 is supported by the housing 22.

[0075] The slider 40 is a quadrilateral plate that extends in a direction intersecting axis A. A mounting groove 40a is formed in the slider 40 for mounting the locking pin 39, 39a. Furthermore, a reinforcing portion 40b, thicker than other portions, is provided on the outer periphery of the slider 40, extending in the forward / backward direction (vehicle width direction) of the locking member 38.

[0076] A through hole 40c is formed in the slider 40 for the connector 27 to pass through. The edge of the through hole 40c located on the side of the locking pin 39 forms a sliding contact part (cam follower) 40d. The sliding contact part 40d is slid into contact with the locking arm part (cam) 27d of the connector 27 by the locking and unlocking operation of the operating knob 26, so that the locking pin 39 moves in and out along the vehicle width direction as a whole.

[0077] The sliding contact portion 40d has a thickness that allows the locking arm portion 27d of the connector 27 to slide in the direction extending along axis A. Figure 11 And refer to Figure 12A and Figure 12B When the operating knob 26, including the connector 27, is in the non-pressed position, the locking arm 27d is positioned rearward in the vehicle length direction, spaced apart from the sliding contact portion 40d. Therefore, in this state, even if the operating knob 26 is rotated, it will spin freely, and the locking arm 27d cannot make sliding contact with the sliding contact portion 40d. On the other hand, combined with... Figure 11 And refer to Figure 13A and Figure 13BWhen the operating knob 26, including the connector 27, is in the pressed position, the locking arm 27d is located in the through hole 40c at the corresponding position in the vehicle length direction relative to the sliding contact portion 40d. Therefore, in this state, when the operating knob 26 is rotated, the locking arm 27d can slide into contact with the sliding contact portion 40d.

[0078] Reference Figure 8 , Figure 10 as well as Figure 11 The sliding contact portion 40d has an inclined edge 40e that is inclined relative to the advancing and retreating direction of the locking member 38 and a locking edge 40f that extends in a direction orthogonal to the advancing and retreating direction of the locking member 38.

[0079] The inclined edge 40e is inclined away from the axis B of the locking pin 39 relative to the direction of advance of the locking pin 39. The inclined edge 40e moves the locking member 38 to the engaged position (see reference) through the sliding contact of the locking arm 27d, achieved by the locking operation of the operating knob 26. Figure 5 On the other hand, the tilting edge 40e, through the rotation of the locking arm 27d achieved by the unlocking operation of the operating knob 26, allows the locking member 38 to move to the non-engaged position (see reference). Figure 3 The tilt angle θ of the tilting edge 40e relative to the moving direction (vehicle width direction) of the locking member 38 is set to the following dimensions: it can ensure the forward distance of the locking member 38 achieved by the locking operation of the operating knob 26 and minimize the force required for operation.

[0080] The locking edge 40f is positioned adjacent to the end of the inclined edge 40e on the non-engaged side. When the locking member 38 moves to the engaged position (see reference...), Figure 5 and Figure 14 When the locking arm 27d of the connector 27 is engaged with the locking edge 40f, the locking edge 40f can also be tilted from the end of the inclined edge 40e in the direction of advancement of the locking member 38.

[0081] Reference Figure 11 , Figure 14 as well as Figure 17 A rotation limiting part is provided between the locking member 38 and the connector 27 to restrict the rotation of the connector 27 in the unlocking operation direction. More specifically, the rotation limiting part consists of a locking arm (first rotation limiting part) 27d provided on the connector 27 and a locking protrusion (second rotation limiting part) 40g provided on the sliding contact part 40d of the slider 40. Figure 2 For reference, when the operating knob 26 is in the locked position 22c, the locking arm 27d and the locking protrusion 40g cooperate to restrict the rotation of the operating knob 26 toward the disconnected position 22a.

[0082] The locking arm 27d of the connector 27 protrudes radially outward from the main portion 27a about the axis A. More specifically, the main portion 27a of the connector 27 has a recess 27e that allows the sliding contact portion 40d of the slider 40 to enter. The locking arm 27d is located on the outer periphery of the portion of the main portion 27a with the recess 27e, and extends circumferentially about the axis A toward the locking operation side of the operating knob 26 (in... Figure 11 and Figure 14 The center is tilted (clockwise).

[0083] Combination Figure 2 And refer to Figure 11 When the operating knob 26 is in the off position 22a, the locking arm 27d extends along the inclined edge 40e. Figure 2 And refer to Figure 14 When the operating knob 26 is in the locked position 22c, the locking arm 27d extends along the axis B of the locking pin 39. The width of the locking arm 27d in the direction extending along axis A is wider than the thickness of the sliding contact portion 40d. The thickness of the locking arm 27d in the circumferential direction around axis A is set as follows: when the locking member 38 moves to the engaged position (refer to...) Figure 5 When this is done, it ensures that the locking member 38 is prevented from moving toward the non-engaged position (see reference). Figure 3 The rigidity of the movement.

[0084] The top portion 27h of the locking arm 27d that slides in contact with the inclined edge 40e of the slider 40 is formed into an arc shape that bulges outward in a generally radial direction. The abutting portion 27i of the locking arm 27d that abuts against the locking edge 40f is formed by the edge formed by the intersection of the arc-shaped top portion 27h and the side portion.

[0085] The locking protrusion 40g of the slider 40 is located between the inclined edge 40e and the locking edge 40f (the intersecting part). When viewed from the direction extending from axis A, the locking protrusion 40g is approximately semi-circular in shape, protruding from the locking edge 40f toward the main part 27a of the connector 27. Thus, as Figure 17 As shown, in the direction of the unlocking operation at connector 27 (in Figure 17 When rotating (in a counter-clockwise direction), the rotation of the connector 27 is restricted by locking the locking arm 27d and the locking protrusion 40g. The radius of curvature of the locking protrusion 40g is preferably as small as possible within the range that can restrict the rotation of the connector 27; in this embodiment, it is set to 0.8 mm.

[0086] like Figure 10As most clearly shown, in the sliding contact portion 40d, the thickness of a portion of the locking edge 40f, including the locking protrusion 40g adjacent to the inclined edge 40e, is thicker than the thickness of the other portions. In other words, the portion of the locking edge 40f including the locking protrusion 40g adjacent to the inclined edge 40e is provided with a block-shaped protrusion 40h that protrudes rearward in the vehicle length direction.

[0087] Combination Figure 5 and Figure 14 And refer to Figure 16A and Figure 16B When the operating knob 26 is in the locked position 22c (refer to...) Figure 2 When the connector 27 is moved to the non-pressed position, the locking arm 27d of the connector 27 is locked to the protrusion 40h of the locking edge 40f. That is, the protrusion 40h protrudes to a position corresponding to the locking arm 27d of the connector 27 in the non-pressed position, and also serves to maintain the locking member 38 in the engaged position.

[0088] Combination Figure 2 And refer to Figure 3 and Figure 8 When the operating knob 26 is in the non-pressed state and in the open position 22a, even if the operating knob 26 is rotated to the seat position 22e in the same rotation direction as the locked position 22c, the locking arm 27d of the connector 27 will not interfere with the protrusion 40h. This is because the angular range from the open position 22a to the seat position 22e is smaller than the angular range from the open position 22a to the locked position 22c.

[0089] Next, the operation of the connector 27 and locking member 38 as described above will be explained.

[0090] Locking handle (see reference) Figure 1 When, such as Figure 11 , Figure 12A as well as Figure 12B As shown, when the operation knob 26 is in the non-pressed position (refer to...) Figure 3 And it is in the disconnected position 22a (refer to) Figure 2 In the current state, press the operation knob 26. Thus, as... Figure 11 , Figure 13A as well as Figure 13B As shown, when the connector 27 moves to the pressing position, the locking arm 27d of the connector 27 moves to the corresponding position in the length direction relative to the sliding contact 40d of the slider 40.

[0091] Next, rotate the operating knob 26 from the off position 22a to the locked position 22c (see reference). Figure 2 Thus, through the rotation of joint 27, the locking arm 27d slides into contact with the inclined edge 40e of slider 40. As a result, as... Figure 14 , Figure 15A as well as Figure 15B As shown, the locking member 38 moves to the engaged position, and the locking arm 27d is locked to the locking edge 40f.

[0092] Next, stop pressing the knob 26. Thus, as... Figure 14 , Figure 16A as well as Figure 16B As shown, when connector 27 moves to the non-pressed position, the locking arm 27d of connector 27 locks into the protrusion 40h, which is part of the locking edge 40f. The result is as follows: Figure 5 As shown, it can maintain the state in which the locking member 38 is engaged with the steering shaft 2 (handle locked state).

[0093] Here, in Figure 5 In the locked state of the handle shown, the ball 35 constituting the positioning mechanism 33 is engaged with the positioning recess 36. Furthermore, the engaging protrusion 27f of the connector 27 engages with the engaging recess 32a of the contact bracket 32. The resistance generated between the ball 35 and the positioning recess 36 by the applied force of the coil spring 34, i.e., the resistance inhibiting the rotation of the contact bracket 32, is greater than the applied force of the coil spring 41 that applies force to the locking member 38 towards the non-engaged position. Therefore, the operating knob 26 is positioned via the connector 27 in a state where it cannot be rotated with a force sufficient for contact.

[0094] In the absence Figure 17 In the case of the locking protrusion 40g shown, when the resistance between the ball 35 and the positioning recess 36 decreases due to wear from years of use, the operating knob 26 can be rotated with a force sufficient for contact. In contrast, in this embodiment, a locking protrusion 40g is provided on the locking edge 40f, including the protrusion 40h, in the sliding contact portion 40d. Therefore, in the unlocking operation direction (in... Figure 17 The rotational force (counterclockwise) acts on Figure 17 When the connector 27 is shown, the locking arm 27d is locked onto the locking protrusion 40g. This restricts the rotation of the connector 27, thus maintaining the locking member 38 in the engaged position. As a result, accidental unlocking of the handle locking device 20 is prevented, improving the anti-theft capability of the vehicle 1.

[0095] On the other hand, when releasing the handle (see reference) Figure 1 When locking, such as Figure 14 , Figure 16A as well as Figure 16B As shown, when the operation knob 26 is in the non-pressed position (refer to...) Figure 5 And it is in the locked position 22c (refer to) Figure 2 In the current state, press the operation knob 26. Thus, as... Figure 14 , Figure 15A as well as Figure 15B As shown, when the connector 27 moves to the pressing position, the locking arm 27d of the connector 27 moves to the corresponding position in the length direction relative to the sliding contact 40d of the slider 40.

[0096] Next, rotate the operating knob 26 from the locked position 22c to the disengaged position 22a (see reference). Figure 2 Therefore, as Figure 11 , Figure 13A as well as Figure 13B As shown, by rotating the connector 27, the locking arm 27d passes over the locking protrusion 40g of the slider 40 and is positioned along the inclined edge 40e, and the locking member 38 moves to the non-engaged position. Then, the pressing operation of the operating knob 26 is stopped. Thus, as... Figure 11 , Figure 12A as well as Figure 12B As shown, connector 27 moves to the non-pressed position. The result is, as... Figure 3 As shown, locking component 38 disengages from steering shaft 2, and handle 3 (see reference) Figure 1 The lock on the handle has been released (handle unlocked).

[0097] Reference Figure 3 as well as Figures 7 to 9 The cover rod 43 is positioned at a distance from the locking member 38 on the front side in the vehicle length direction. A through hole 43a is formed in the cover rod 43 for the connector 27 to pass through. A pair of operating receiving parts 43b protruding inward in a radially opposite position are provided at the edge of the through hole 43a.

[0098] like Figure 2 and Figure 4 As shown, when the operating knob 26 and connector 27 are in the pressed position, a pair of operating protrusions 27g, protruding radially outward from the main portion 27a of connector 27, are located within the through hole 43a of cover rod 43. Therefore, when the operating knob 26 is rotated from the off position 22a to the cover position 22d in this state, the operating protrusions 27g of connector 27 abut against the operating receiving portion 43b, and cover rod 43 rotates. Thus, cover 4 (see reference 4) can be opened via wire 44. Figure 1 ).

[0099] Reference Figure 3 as well as Figures 7 to 9 The seat rod 45 and the cover rod 43 are arranged adjacent to each other on their rear sides along the vehicle length. A through hole 45a is formed in the seat rod 45 for the connector 27 to pass through. A pair of operating receiving parts 45b protruding inward in a radially opposite position are provided on the edge of the through hole 45a.

[0100] like Figure 2 and Figure 3As shown, when the operating knob 26 and connector 27 are in the non-pressed position, the pair of operating protrusions 27g of connector 27 are located within the through hole 45a of seat rod 45. Therefore, when the operating knob 26 is rotated from the off position 22a to the seat position 22e in this state, the operating protrusions 27g of connector 27 abut against the operating receiving part 45b, and seat rod 45 rotates. Thus, seat 5 can be opened via wire 46 (see reference). Figure 1 ).

[0101] Reference Figure 3 and Figure 7 The cover lever 43 and seat lever 45 are forced towards the neutral position by the return spring 47. One end of the return spring 47 is engaged with the cover lever 43, and the other end is engaged with the seat lever 45. When the cover operation and seat operation are stopped, the cover lever 43 and seat lever 45 are returned to the neutral position by the force applied by the return spring 47. As a result, the operating knob 26 is returned to the disengaged position 22a via the connector 27 (see reference). Figure 2 ).

[0102] The handle locking device 20 thus constructed has the following characteristics.

[0103] A rotation limiting portion 27d and a rotation limiting portion 40g are provided between the connector 27 and the locking member 38. These rotation limiting portions 27d and 40g restrict the rotation of the connector 27 when the operating knob 26 is in the locked position 22c. Therefore, regardless of the wear condition of the positioning mechanism 33 (especially the positioning recess 36), even if the user touches the operating knob 26 when the handle locking device 20 is in the locked state, the rotation limiting portion 27d and the rotation limiting portion 40g can restrict the rotation of the connector 27. As a result, the locking member 38 can be maintained in the engaged position by the connector 27, thus preventing accidental unlocking of the handle locking device 20 and improving the anti-theft capability of the vehicle 1.

[0104] The engaging recess 32a of the contact bracket 32 ​​and the engaging protrusion 27f of the connector 27 are disengaged by the movement of the connector 27 to the pressed position, achieved by pressing the operating knob 26. Therefore, when the operating knob 26 is rotated in this state, the connector 27 rotates relative to the contact bracket 32, while the contact bracket 32 ​​does not rotate. This reduces the rotation frequency of the contact bracket 32, thereby suppressing wear on the positioning mechanism 33.

[0105] The structure of the locking member 38 for moving forward and backward by rotating the connector 27 is already complex, and it becomes even more complex by providing rotation limiting parts 27d and 40g. In contrast, the locking member 38 is intentionally composed of two parts: a locking pin 39 having a locking recess 2a that can be inserted into the steering shaft 2, and a slider 40 that can move forward and backward by rotating the connector 27. This allows for a reliable structure including the rotation limiting parts 27d and 40g that move forward and backward by rotating the connector 27.

[0106] The locking pin 39 is always forced to the non-engaged position by the force applied by the coil spring 41. Thus, during the movement of the vehicle 1, the locking member 38 can be reliably prevented from engaging with the steering shaft 2 due to vibration or other factors, thereby locking the handle 3.

[0107] The connector 27 has a locking arm (first rotation limiting part) 27d that protrudes radially outward from the main part 27a of the connector 27 about the axis A of the operating knob 26. Furthermore, the locking member 38 has a locking protrusion (second rotation limiting part) 40g that protrudes from the sliding contact part 40d of the connector 27. Thus, by locking the locking arm 27d of the connector 27 against the locking protrusion 40g of the locking member 38, the rotation of the connector 27 can be reliably limited.

[0108] The sliding contact portion 40d includes: an inclined edge 40e for moving the locking member 38 between an engaged position and a non-engaged position; and a locking edge 40f for locking the connector 27 when the locking member 38 is moved to the engaged position, with a locking protrusion 40g disposed between the inclined edge 40e and the locking edge 40f. Thus, when the locking member 38 is in the engaged position, rotation of the connector 27 caused by rotation of the operating knob 26 from the locked position 22c to the disengaged position 22a can be reliably limited.

[0109] The sliding contact portion 40d of the locking member 38 has a thickness sufficient for the connector 27 to make sliding contact, and the thickness of a portion of the locking edge 40f of the locking protrusion 40g adjacent to the inclined edge 40e is thicker than the thickness of other portions. This increases the strength of the portion of the locking member 38 including the locking protrusion 40g. Furthermore, the protrusion 40h, which is part of the locking edge 40f including the locking protrusion 40g, protrudes to a position where it can be engaged by the locking arm portion 27d of the connector 27 when it is moved to a non-pressed position. Therefore, even when the connector 27 is moved to a non-pressed position, the locking member 38 can be maintained in the engaged position.

[0110] Hereinafter, other embodiments and various modifications of the present invention will be described, in which points not specifically mentioned are the same as in the first embodiment. In the drawings mentioned below, the same reference numerals are used to denote the same elements as in the first embodiment.

[0111] (Second Implementation)

[0112] Reference Figure 18 The handle locking device 20 in the second embodiment replaces... Figure 3 The operating knob 26 shown is different from the handle locking device 20 of the first embodiment in that the operated component is composed of a mechanical key 55 and a lock cylinder 56. In the handle locking device 20 of the second embodiment, no... Figure 1 The electronic key 15 shown is therefore not used. Figure 1 and Figure 3 The limiting mechanism shown is 50.

[0113] The lock cylinder 56 is integrally located at the rear end of the connector 27 in the longitudinal direction. The lock cylinder 56 can also be separately located from the connector 27 and installed so that it can move integrally with the connector 27. The lock cylinder 56 includes: a keyhole 56a for inserting a mechanical key 55; and a plurality of tumblers 57, which are stressed by springs (not shown).

[0114] When the standard mechanical key 55 is not inserted into the keyhole 56a, a portion of the pin 57 protrudes from the lock cylinder 56 and engages with a locking groove (not shown) in the housing 22. This restricts the rotation of the connector 27, including the lock cylinder 56. On the other hand, when the standard mechanical key 55 is inserted into the keyhole 56a, the pin 57 is inserted into the lock cylinder 56, releasing the engagement with the locking groove in the housing 22. This allows the rotation of the connector 27, including the lock cylinder 56.

[0115] The connector 27 has the following features Figure 8 The structure of the locking arm 27d, the positioning mechanism (not shown) of the contact bracket 32, and the locking member 38 are the same as in the first embodiment. Therefore, the handle locking device 20 of the second embodiment can achieve the same function and effect as the first embodiment.

[0116] (Third implementation method)

[0117] Reference Figure 19 and Figure 20 The handle locking device 20 of the third embodiment differs from the handle locking device 20 of the first embodiment in that the contact bracket 32 ​​is mounted so that it rotates integrally with respect to the connector 27. In the handle locking device 20 of the third embodiment, similarly to the first embodiment, a method is used... Figure 1 The electronic key 15 shown is therefore used. Figure 1 and Figure 3 The limiting mechanism shown (not illustrated).

[0118] In the handle locking device 20 of the third embodiment, no... Figure 3The cover rod 43 and seat rod 45 are shown. A structure, as in the third embodiment, that allows the contact bracket 32 ​​to rotate integrally with respect to the connector 27 can also be applied. Figure 18 The handle locking device 20 shown is a second embodiment using a mechanical key 55 and a lock cylinder 56.

[0119] Specifically, no connector 27 or contact bracket 32 ​​is provided in the third embodiment. Figure 3 The engaging protrusion 27f and engaging recess 32a are shown. The top portion 27j of the connector 27 has a non-circular cross-section and is installed in a way that allows it to move in and out relative to the mounting hole 32d in the contact bracket 32, which has a non-circular cross-section corresponding to the top portion 27j, but cannot rotate.

[0120] The connector 27 has the following features Figure 8 The structure of the locking arm 27d, the positioning mechanism (not shown) of the contact bracket 32, and the locking member 38 shown are the same as in the first embodiment. Therefore, the handle locking device 20 of the third embodiment can achieve the same function and effect as the first embodiment.

[0121] It should be noted that the present invention is not limited to the structure of the described embodiments, and various modifications can be made.

[0122] For example, the operated component including the connector 27 (operating knob 26 or mechanical key 55 and lock cylinder 56) can be rotated about axis A, or it can be a structure that cannot move forward or backward along axis A.

[0123] The structure for switching the engagement state of the connector 27 and the contact bracket 32 ​​is not limited to the engagement protrusion 27f and the engagement recess 32a. It can be any structure that switches to the engagement state by not pressing the operation knob 26 and switches to the non-engaged state by pressing the operation knob 26. It can be changed as needed.

[0124] The locking member 38 is not limited to a structure consisting of only two parts: the locking pin 39 and the slider 40. As long as a locking protrusion (rotation restriction part) 40g is provided in the sliding contact portion 40d, it can be composed of one part or three or more parts. In addition, it can also be a structure in which the locking member 38 is not subjected to force in the non-engaged position without using the coil spring 41.

[0125] The rotation limiting part is not limited to a structure consisting of a locking arm (first rotation limiting part) 27d provided on the connector 27 and a locking protrusion (second rotation limiting part) 40g provided on the sliding contact part 40d of the slider 40. It can be any structure that can limit the rotation of the connector 27 when the operating knob 26 is in the locked position 22c, and can be changed as needed.

[0126] The structure for switching the engagement state of the locking member 38 is not limited to the structure consisting of the locking arm (cam) 27d of the connector 27 and the sliding contact part (cam follower) 40d of the locking member 38. It can be any structure that can move the locking member 38 forward and backward in conjunction with the rotation of the connector 27, and can be changed as needed.
