Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock device, and more particularly to a steering lock device that ensures safety when starting an engine of a vehicle having an automatic transmission.

2. Description of the Related Art In a vehicle equipped with a shift lever that operates an automatic transmission, a safety device that prevents sudden starting at the time of starting the vehicle that occurs when the shift lever is operated from a parking position to another position when the engine is started is provided. Provided. For example, as shown in Japanese Utility Model Laid-Open Publication No. 64-52935, in a safety device configured by using electric means, when the ignition switch is turned on, the depression state of the brake pedal is detected and the shift lever is operated. It is possible to shift from the parking position to another position. In this structure, a brake switch that detects depression of a brake pedal and a solenoid that controls pressing of a knob of a shift lever are provided. When the ignition switch is switched to the on position and the brake switch is turned on, the solenoid moves to a position that allows the knob of the shift lever to be pressed.

However, in the structure using the above-described electrical configuration, the cost of the safety device cannot be reduced. Therefore, a mechanical safety device using a wire has recently been developed. For example, Akira Kai
Japanese Patent Application Laid-Open Nos. 64-47432 and 1-154928 disclose an AT shift lock in which when the brake pedal is depressed, the lock plate and the detent pin are disengaged and the shift lever can be operated from the parking position to another position. An apparatus is disclosed. Japanese Utility Model Laid-Open Publication No. 1-150877 discloses that after switching the steering lock device to the ACC position, the shift lever can be moved to a position other than the parking position, and if the shift lever is not returned to the parking position, the shift from the ACC position is performed. A vehicle key interlock device in which a key cylinder cannot be rotated to a locked position is disclosed. Furthermore, Japanese Utility Model Laid-Open No. 1-114325 discloses a lock of a shift lever which can move the shift lever from the parking position to another position only when the key cylinder is rotated to the ACC position or the ON position and the brake pedal is depressed. An apparatus is disclosed.

SUMMARY OF THE INVENTION In the interlock device disclosed in Japanese Utility Model Laid-Open No. 1-150877, it is possible to move the shift lever to a position other than the parking position after rotating the key to the ACC position. Further, in the lock device disclosed in the specification of Japanese Utility Model Laid-Open No. 1-114325, when the key is rotated to the ACC position and then the brake pedal is depressed, the shift lever can be moved to a position other than the parking position. That is, the key is AC
The technique suggests that the engagement between the cam projection of the key rotor and the tip of the lock lever is released so that the shift lever can be moved to a position other than the parking position when rotated to the C position or the ON position. When the shift lever is in a position other than the parking position, the key is rotated from the ON position to the ACC position, and when the engine is stopped, the shift lever is moved in the ACC position. This is because it is possible to move to the parking position. However, when starting, once the brake pedal is depressed when turning the key from the lock position to the ACC position, the shift lever can be moved to a position other than the parking position, so depress the brake immediately after starting the engine in the neutral position If the shift lever is moved to the drive position without any trouble, there is a risk of sudden start. Therefore, with this structure, safety at the time of starting the engine cannot be sufficiently ensured. For this reason, it is desirable that a structure in which the shift lever cannot be moved to a position other than the parking position when the key is rotated from the lock position to the ACC position is desirable.

In view of the above, it is an object of the present invention to provide a steering lock device that prevents a shift lever from moving when a key is rotated from a lock position to an ACC position in response to the above demand.

The applicant of the present application has previously described a structure for preventing a shift lever from moving when a key is rotated from a lock position to an ACC position with respect to a vertical steering lock device in which a central axis is arranged substantially parallel to a steering shaft. Filed a patent application. However, for a horizontal steering lock device in which the central axis is disposed at substantially right angles to the steering shaft, a structure for preventing the shift lever from moving when the key is rotated from the lock position to the ACC position has been proposed. Not. Therefore, the present invention provides an interlocking structure between a shift lever and a key cylinder, which is particularly suitable for a horizontal steering lock device.

Means for Solving the Problems In a steering lock device according to the present invention, a key cylinder rotatably arranged by a key in a frame between a lock position for locking a steering shaft and an unlock position for unlocking the steering shaft is provided. A control lever connected to the key plate by a cable and operatively connected to a key cylinder when the shift lever for operating the automatic transmission is moved from the parking position to another position. The control lever swings between a block position that prevents the shift lever from moving and a release position that allows the shift lever to move.

The stopper portion is provided on the key cylinder or a rotating member connected to the key cylinder. The stopper portion includes a first stopper surface for preventing the control lever from swinging to the release position when the key cylinder is at the lock position, and the key cylinder includes:
A second stopper surface that prevents rotation of the key cylinder to the locked position when the control lever is in the ACC position and the control lever is in the release position. The one-way swing restricting means prevents the control lever from swinging to the release position when the key cylinder is at the ACC position and the control lever is at the block position, while the key cylinder is at the ACC position and the control lever is released. When in the position, the control lever is allowed to swing to the block position.

The stopper is formed integrally with the latch member and is urged by the elastic member. In the embodiment of the present invention, the control lever can swing from the block position to the release position only when the brake pedal is depressed.

The one-way swing restricting means has a latch member disposed in a hole of the key cylinder or the rotating member, and an elastic member for urging the latch member toward the outside of the hole of the key cylinder or the rotating member. The latch member is provided with a radial surface that forms substantially the same plane as the stopper surface, and an inclined surface formed on the back side of the radial surface. When the key cylinder is in the ACC position and the control lever is in the block position, the control lever contacts the radial surface of the latch member to prevent the control lever from swinging to the release position. When the key cylinder is in the ACC position and the control lever is swung from the release position to the block position, the control lever contacts the inclined surface of the latch member and the latch member moves radially inward against the elastic force of the elastic member. Then, the control lever can be swung to the block position.

In another embodiment of the present invention, the one-way swing restricting means includes a stop portion elastically supported by the control lever and an additional stopper provided on the key cylinder or the rotating member. The additional stop has a radial surface that is substantially coplanar with the first stop surface of the stop, and an inclined surface provided on the back side of the radial surface. When the key cylinder is in the ACC position and the control lever is in the blocking position, the stop of the control lever abuts the radial surface of the additional stop to prevent swinging of the control lever to the release position. When the key cylinder is in the ACC position and the control lever is pivoted from the release position to the block position, the stop of the control lever can resiliently ride over the inclined surface of the additional stop to pivot to the block position. The stop has a pin supported in the hole of the control lever, and an elastic member for urging the pin toward the outside of the hole of the control lever.

When the key cylinder is rotated from the lock position to the ACC position, the swing restriction means prevents the control lever in the block position from swinging to the release position. Therefore, the shift lever is held at the parking position, and the output shaft of the transmission is maintained in a mechanically fixed state, so that the vehicle does not move due to its own gravity even on an inclined road. Once the key cylinder is rotated from the ACC position to the ON position, the shift lever can be moved from the parking position to another position. Also, regardless of the position of the shift lever, the key cylinder in the ON position can be immediately switched to the ACC position to stop the engine. Further, when the key cylinder is rotated to the ACC position and the control lever is at the release position, the control lever comes into contact with the second stopper surface of the stopper portion. For this reason,
Since the control lever prevents the rotation of the key cylinder, the rotation of the key cylinder to the locked position is prevented. Therefore,
The driver can recognize that the shift lever is returned to the parking position. In this case, since the one-way swing restricting means allows the shift lever at the release position to swing to the block position, the shift lever can be smoothly returned to the parking position.

The latch member constituting the one-way swing restricting means is arranged in the hole of the key cylinder or the rotating member, and is urged to the outside of the hole by the elastic member. The radial surface of the latch member prevents the control lever in the blocking position from swinging to the release position. The inclined surface of the latch member allows the control lever at the release position to swing to the block position. That is, when the control lever swings to the block position, the latch member is moved radially inward against the elasticity of the elastic member by the inclined surface of the latch member, and the control lever can swing along the inclined surface. Become.

According to another embodiment of the present invention, the movement of the stop provided as the one-way swing restricting means and elastically supported by the control lever is performed by a cam surface provided on the key cylinder or the rotating member. Is regulated by an additional stopper formed as a That is, the stop abuts against the radial surface of the additional stopper. At this time, the swing of the control lever from the block position to the release position is prevented. Also, when the key cylinder is in the ACC position and the control lever is in the release position, the control lever can smoothly move from the release position to the block position because the stop can elastically climb over the inclined surface of the additional stopper. Rocked.

Embodiment An embodiment of the present invention will be described below with reference to FIGS.

First, in FIG. 10 and FIG.
Is rotatably supported via a rotating shaft 116. The shift lever 110 is rotated to a shift position such as a parking position P, a reverse shift position R, a neutral shift position N, and a traveling shift position provided in the opening 121 of the control plate 120. The handle of the shift lever 110 is provided with a knob 111, and the knob 11
1 is pressed by the rod 11 inserted in the control lever tube 112.
3 is transmitted as vertical motion. Further, the shift pin 114 provided at the tip of the rod 113 is pushed down against the elasticity of the spring 115. When the shift pin 114 is engaged with the parking position P by the pressing force of the spring 115 as shown in FIG. 10, the shift lever 110 cannot move from the parking position P to another shift position as shown in FIG. .

The rotation lever 130 is rotatably supported via a shaft 131 at a position substantially below the parking position P of the control plate 120. The pivot lever 130 is formed with a pin engaging end 130a and a cable connecting end 130b extending from both sides of the shaft 131, respectively, and an initial stage in which the shift pin 114 shifts from the parking position P to, for example, the next reverse shift position R. Then, the shift pin 114 presses the pin engagement end 130a, and the rotation lever 130
Is rotated counterclockwise around the shaft 131.
The other end of the cable 140 having one end connected to the control lever 50 of the steering lock device 10 is connected to the connection end 130b. The rotating lever 130 swings around the shaft 131 by the force of each of the pin engaging end 130a and the connecting end 130b.

When the knob 111 of the shift lever 110 is pressed, the shift pin
114 is pushed down against the spring 115, and the rotating lever
It reaches inside the engagement end 130a of 130. When the shift lever 110 is shifted to a position other than the parking position in this position, the shift pin 114 presses the engagement end portion 130a of the rotation lever 130 by the rotation of the shift lever 110, and the rotation lever 110 rotates around the shaft 131. Rotate the entire 130 counterclockwise.

Due to the rotation of the rotation lever 130, the cable 140 is pulled to the left in the drawing at the connection end 130b as shown in FIG.
At the same time, the opening 12 closed by the engagement end 130a
The gap 122 on the first side is opened, and the shift pin 1
14 moves toward another shift position. That is, the rotation of the rotation lever 130 pulls the cable 140. Movement of the shift lever 110 causes the shift pin 114 to rotate.
When the rotating lever 130 is disengaged from the engaging end portion 130a of the 130, the rotating lever 130 is held in an inclined state. When the shift lever 110 is returned to the parking position P again, the shift pin 114 rotates the rotation lever 130 clockwise, and the rotation lever 130 is moved to the eleventh position.
The state shown in FIG. 10 is returned to the state shown in FIG. When the shift lever 110 moves from the parking position P to another position, the cable 140 to which the pulling force is applied is in a pull state. Conversely, when the shift lever 110 is returned to the parking position P, the cable 140 to which a compressive force is applied is in a push state.

The key cylinder 16 is mounted in a hole 24 of a rotating member 23 rotatably and coaxially arranged within the frame 11. In addition, the key cylinder 16 is
Inside, it is pressed outward by a spring 25 disposed between the key cylinder 16 and the rotating member 23. Further, the locking rod 18 is attached so as to be able to advance and retreat from the hole 19 of the frame 11. However, the check lever 20, the dog 22, and the locking rod 18 have the same structure and operation and effect as those disclosed in Japanese Patent Publication No. 60-42055. Also, a key detection member
26 and the key detection switch 27 have the same structure, operation and effect as those disclosed in JP-A-59-3829. Therefore, these detailed explanations are omitted.

As shown in FIG. 1 and FIG.
Is formed. A latch member 31 as a one-way swing restricting means is slidably disposed in the hole 30. In the hole 30, a spring 32 is provided as an elastic member for urging the latch member 31 to the outside of the rotating member 23. The latch member 31 is manufactured in substantially the same manner as a conventionally used disk tumbler. The latch member 31 is formed with a hole 31a through which a pin 33 fixed in the hole 23a of the rotating member 23 passes. As shown, a radial surface 35 and an inclined surface 36 are formed on the protruding end 34 of the latch member 31.

As shown in FIGS. 3 and 4, a stopper 40 is provided on the outer peripheral surface of the rotating member 23. The stopper portion 40 has a first stopper surface 40a and a second stopper surface 40b formed substantially at right angles to the first stopper surface 40a. 4th
As shown in the figure, the frame 11 has a block position (FIG. 4A) that prevents the shift lever 110 from moving and a release position (FIGS. 4B to 4D) that allows the shift lever 110 to move.
A control lever 50 swinging between the control lever 50 is provided. The control lever 50 is used to move the shift lever 110 for operating the automatic transmission from the parking position to another position.
A cable 140 is connected to a rotating lever 130 that controls the movement of the 110. Further, the control lever 50 is provided rotatably supported by the bracket 60 with a shaft portion 51 and fixed to one end of the shaft portion 51 and engageable with the first and second stopper surfaces 40a and 40b of the stopper portion 40. Arm portion 52 provided. At one end of the shaft portion 51, a pin 54 is formed, which is inserted and supported by a hole (not shown) of the bracket 60. Further, a pin 53 disposed in the hole 60a of the bracket 60 and one end of the crank 56 are fixed to the other end of the shaft portion 51. A boss 55 is formed at the other end of the crank 56, and a connecting portion 57 having a keyhole-shaped cross section is formed at an end of the boss 55. The connecting portion 57 is provided with a projecting portion 58 formed in a substantially fan shape.

A connector 70 is connected between the control lever 50 and the cable 140. At one end of the connector 70, an opening 71 having substantially the same cross section as the connecting portion 57 of the control lever 50 is formed.
The other end of the connector 70 is connected to the cable end of the cable 140 by the pin 72. The opening 71 having a keyhole-shaped cross section into which the protrusion 58 of the connecting portion 57 is fitted is formed at a large angle, and the connecting portion 57 is rotatable within a certain angle range.
Is inserted into.

4A and 4B show a state in which the control lever 50 is in a block position by hatching, and FIG.
Indicates a state at the release position. When the key cylinder 16 is at the block position shown in FIG. 4A, the arm portion 52 of the control lever 50 at the block position comes into contact with the first stopper surface 40a of the stopper portion 40 and the control lever 50 moves to the release position. Swing is prevented. When the key cylinder 16 is in the ACC position and the control lever 50 is in the release position shown in FIG. 4D, the arm 52 of the control lever 50 is
The key cylinder 16 is prevented from rotating to the lock position by contacting the second stopper surface 40b of the key cylinder 40.

As shown in FIG. 4B, when the key cylinder 16 is in the ACC position and the control lever 50 is in the block position, the control lever 50 is moved to the radial surface 35 of the latch member 31 as shown in FIG.
To prevent the control lever 50 from swinging to the release position. Further, as shown in FIG. 4D, the latch member 31
When the key cylinder 16 is in the ACC position and the control lever 50 is in the release position, the control lever 50 contacts the inclined surface of the latch member 31 and resists the elasticity of the elastic member.
Moves radially inward to allow the control lever 50 to swing to the block position.

In the above configuration, the latch member 31 is
It is located within 30 and is biased out of bore 30 by a spring 32. Key cylinder 16 is locked from the locked position (Fig. 4A).
When rotated to the position (FIG. 4B), the radial surface 35 of the latch member 31 prevents the control lever 50 in the blocking position from swinging to the release position. Therefore, the shift lever 110 is held at the parking position, and the state in which the output shaft of the transmission is mechanically fixed is maintained, so that one end of the shift lever 110 is shifted from the ACC position (FIG. 4B) to the ON position (FIG. 4C). After the key cylinder 16 is rotated, the shift lever 110 can be moved from the parking position to another position. Further, regardless of the position of the shift lever 110, the key cylinder 16 at the ON position can be immediately switched to the ACC position to stop the engine. Further, as shown in FIG. 4D, when the key cylinder 16 is rotated to the ACC position and the control lever 50 is at the release position, the second stopper surface 40b of the stopper portion 40 comes into contact with the control lever 50. Therefore, the control lever 50 prevents the rotation of the key cylinder 16, so that the rotation of the key cylinder 16 to the locked position is prevented. Therefore, the driver can recognize that the shift lever 110 is returned to the parking position.

In this case, the control lever 50 is at the position shown in FIG. 5A. When the control lever 50 swings to the block position, the arm 52 of the control lever 50 comes into contact with the inclined surface 36 of the latch member 31 (FIG. 5B). Further, when the control lever 50 is swung to the block position, the latch member 31 is moved radially inward against the elasticity of the spring 32 by the arm 52 of the control lever 50, as shown in FIG. Since the control lever 50 can swing along the surface 36, the control lever 50 swings to the block position shown in FIG. 5D. Thus, the shift lever 110
Can be smoothly returned to the parking position.

Further, in the embodiment of the present invention, if the shift lever 110 in the parking position is moved to another position by the electric means or the mechanical means only when the brake pedal is depressed, the safety at the time of starting the engine is improved. It will be appreciated that can be improved. In this case, the control lever in the block position can swing to the release position only when the brake pedal is depressed.

Inclined surface 54b. When the key cylinder 16 is in the ACC position and the control lever 50 is in the blocking position, the pin 153 contacts the radial surface 54a of the additional stopper 54 to prevent the control lever 50 from moving to the release position. Therefore, the movement of the control lever 50 from the block position to the release position is prevented. Also, when the key cylinder 16 is in the ACC position and the control lever 50 is moved from the release position to the block position, the pin 153 can move over the inclined surface 54b of the additional stopper 54 elastically and move to the block position. The control lever 50 is smoothly moved from the release position to the block position.

(5) In the above embodiment, the stopper member 40 and the additional stopper portion 54 are provided on the rotating member 23. However, the stopper members 40 and 54 may be formed on the key cylinder 16 instead of the rotating member 23.
