Abstract

PURPOSE:To secure safety at the time of riding by preventing a shift lever from moving when a key is turned from a lock position to an ACC position, and mechanically fixing an output shaft of a transmission at the ACC position. CONSTITUTION:When a key cylinder 16 is turned from a lock position to an ACC position, a one way movement regulating means 31 prevents a first slider 41 in a block position from moving to a release position. Therefore, the first slider 41 is held at an initial position and a shift lever is held at a parking position. Herewith, since a state of an output shaft of a transmission being mechanically fixed is held, an automobile is never moved by its own gravity even on an inclined road. Moreover, it is possible to instantly change over the key cylinder 16 at an ON position to the ACC position irrespective of a position of the shift lever, to stop an engine. It is possible hereby to secure safety at the time of starting the engine of a vehicle.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a locking device, and particularly to a steering locking device that ensures safety when starting the engine of a vehicle equipped with an automatic transmission.

In vehicles equipped with a shift lever that operates an automatic transmission,
A safety device is provided to prevent the vehicle from suddenly starting when the shift lever is operated from the parking position to another position when starting the engine. For example, as shown in Japanese Utility Model Application Publication No. 64-52935, a safety device configured using electrical means detects the depression state of the brake pedal when the ignition switch is turned on and shifts the shift lever. It is possible to shift from the parking position to another position. This structure is provided with a brake switch that detects depression of the brake pedal and a solenoid that controls pressing of the shift lever knob. When the ignition switch is turned on and the brake switch is turned on, the solenoid moves to a position that allows the shift lever knob to be pressed.

However, with the structure using the above-mentioned electrical configuration, it is not possible to reduce the cost of the safety device, so recently, mechanical safety devices using wires have been developed. For example, Jitsukai Showa 6
4-47432 and Utility Model Application Publication No. 1-154928 disclose an AT shift system in which when the brake pedal is depressed, the engagement between the lock plate and the detent pin is disengaged, allowing the shift lever to be moved from the parking position to another position. A locking device is disclosed. Also, Utility Model Application Hei 1-150877
The publication states 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 the key cylinder cannot be rotated from the ACC position to the lock position unless the shift lever is returned to the parking position. A vehicle key interlock device is disclosed.

Furthermore, Japanese Utility Model Application No. 1-114325 discloses a shift lever lock that allows the shift lever to be moved 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.

However, in the interlock device disclosed in Japanese Utility Model Publication No. 1-150877, after the key is rotated to the ACC position, it is possible to move the shift lever to a position other than the parking position. Further, in the locking device disclosed in Japanese Utility Model Application No. 1-114325, when the key is rotated to the ACC position and the brake pedal is depressed, the shift lever can be moved to a position other than the parking position. That is, when the key is rotated to the ACC position or the ON position, the engagement between the cam protrusion 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 the shift lever is in a position other than the parking position, if the key is turned from the on position to the ACC position and the engine is stopped, the shift lever can be moved to the parking position in the ACC position. However, when starting the engine, if you step on the brake pedal once you turn the key from the lock position to the ACC position, you can move the shift lever to a position other than the parking position, so immediately after starting the engine in the neutral position, If you move the shift lever to the drive position without stepping on the brake, there is a risk of a sudden start. Therefore, with this structure, it is not possible to sufficiently ensure safety when starting the engine. For this reason, move the key from the lock position to ACC.
It is desirable to have a structure in which the shift lever cannot be moved from the parking position to any other position when the shift lever is rotated to the parking position.

Therefore, in response to the above-mentioned request, the present invention has been devised so that when the key is rotated from the lock position to the ACC position, the shift lever
An object of the present invention is to provide a steering lock device that prevents movement of the steering wheel.

A steering lock device according to the present invention includes a key cylinder rotatably arranged within a frame with a key between a lock position for locking the steering shaft and an unlock position for unlocking the steering shaft. a first shift lever connected by wire to a control member for controlling movement of the shift lever for operating the automatic transmission when moving the shift lever from a parking position to another position and movable between an initial position and an operating position; and a second slider cam-connected to the first slider. The second slider moves between a blocking position that prevents movement of the shift lever and a release position that allows movement of the shift lever. The key cylinder or the rotating member connected to the key cylinder has a stopper portion. The stopper portion includes a first stopper surface that prevents the second slider from moving to the release position when the key cylinder is in the lock position, and a first stopper surface that prevents the second slider from moving to the release position when the key cylinder is in the ACC position and the second slider is in the release position. and a second stopper surface that prevents the cylinder from moving to the lock position. A one-way movement restricting means is provided adjacent to the stopper portion. This one-way movement restricting means prevents the second slider from moving to the release position when the key cylinder is in the ACC position and the second slider is in the blocking position, and also prevents the second slider from moving to the release position when the key cylinder is in the ACC position and the second slider is in the blocking position. When the second slider is in the release position, the second slider is allowed to move to the block position.

The stopper portion is formed integrally with the latch member and is biased by an elastic member. In an embodiment of the invention, the slider can only be moved from the blocking position to the releasing position when the brake pedal is depressed.

For example, the movement restricting means includes a latch member disposed within a hole of the key cylinder or rotating member, and an elastic member that biases the latch member toward the outside of the hole of the key cylinder or rotating member. The latch member is provided with a radial surface that is substantially coplanar with the stopper surface, and an inclined surface provided on the back side of the radial surface. When the key cylinder is in the ACC position and the second slider is in the blocking position, the second slider abuts against the radial surface of the latch member to prevent movement of the second slider to the release position.

When the key cylinder is in the ACC position and the second slider is moved from the release position to the block position, the second slider contacts the inclined surface of the latch member and resists the elasticity of the elastic member to move the latch member in the radial direction. You can move it inward and move the second slider to the blocking position.

In another embodiment, the one-way movement restricting means includes a stop portion elastically supported by the second slider and an additional stop portion provided on the key cylinder or the rotating member. The additional stopper portion has a radial surface that is substantially coplanar with the first stopper surface of the stopper portion, and an inclined surface provided on the back side of the radial surface. When the key cylinder is in the ACC position and the second slider is in the blocking position, the stop part of the second slider abuts against the radial surface of the additional stopper part to prevent movement of the second slider to the release position. However, when the key cylinder is in the ACC position and the second slider is moved from the release position to the block position, the stop portion of the second slider elastically overcomes the inclined surface of the additional stopper and moves to the block position. can.

The stop includes a pin supported within the hole of the second slider;
and an elastic member that biases the pin toward the outside of the hole of the second slider.

When the key cylinder is rotated from the lock position to the ACC position, the one-way movement restricting means prevents the first slider in the blocking position from moving to the release position. Therefore, the first slider is held at the initial position and the shift lever
is held in the park position. Therefore, the output shaft of the transmission remains mechanically fixed, so that the vehicle does not move due to its own gravity even on a sloped road. After the key cylinder is rotated from the ACC position to the ON position, the engagement between the second slider and the one-way movement restricting means is disengaged, so move the shift lever from the parking position to another position and shift to the first position. The slider can be moved from an initial position to an activated position. At this time, the second slider is moved from the blocking position to the release position by the cam action of the first slider.

Furthermore, regardless of the position of the shift lever, it is possible to immediately switch the key cylinder in the on position to the ACC position to stop the engine.

Furthermore, when the key cylinder is not rotated to the ACC position and the second slider is at the release position, the second slider abuts against the second stopper surface of the stopper portion. For this reason,
The second slider prevents rotation of the key cylinder and movement of the key cylinder to the locked position is prevented. Therefore, the driver is made aware that the shift lever must be returned to the parking position. In this case, when the shift lever is returned to the parking position, the one-way movement restricting means allows the shift lever in the release position to move to the blocking position, so the second slider is released by the cam action of the first slider. from the position back to the blocking position.

The latch member constituting the one-way movement restricting means is disposed within the hole of the kill cylinder or the rotating member, and is biased to the outside of the hole by an elastic member. The radial surface of the latch member prevents movement of the second slider in the blocked position to the released position. Additionally, the inclined surface of the latch member allows movement of the second slider in the release position to the blocking position. That is, when the second slider moves to the blocking position, the latch member is moved radially inward by the inclined surface of the latch member against the elasticity of the elastic member, and the second slider moves along the inclined surface. It becomes possible.

According to another embodiment of the present invention, the movement of the stop portion provided as the one-way movement restricting means and elastically supported by the second slider is controlled by a cam provided on the key cylinder or the rotating member. It is regulated by an additional stop part designed as a surface. That is, the stop part abuts against a radial surface of the additional stop part. At this time, the second slider is prevented from moving from the block position to the lease position. Further, when the key cylinder is in the ACC position and the second slider is in the release position, the stop part elastically overcomes the inclined surface of the additional stop part, and the second slider smoothly moves from the release position to the block position. will be moved to

Embodiments of the present invention will now be described with reference to FIGS. 1 to 20.

First, in FIGS. 18 and 19, the shift lever 1
10 is rotatably supported via rotation 0116. The shift lever 110 is rotated to each shift position provided in the opening 121 of the control plate 120, such as a parking position P, a reverse shift position [R1 neutral shift position N, and a travel shift position. There is a knob 11 on the handle of the shift lever 110.
1 is provided, and the pressure of the knob 111 is transmitted as a vertical movement to the rod 113 inserted into the lever tube 112.

Furthermore, the shift pin 11 provided at the tip of the rod 113
4 is pushed down against the elasticity of the spring 115.

The above structure is well known, and as shown in FIG.

A rotary lever 130 as a control member is rotatably supported via a shaft 131 at a position substantially below the parking position MP of the control plate 120. The rotating lever 130 is formed with a pin engaging end 130a and a cable connecting end 130b extending from both sides of the shaft 131, and the shift pin 114 is at an initial stage when the shift pin 114 moves from the parking position IP to the next reverse shift position R, for example. So, shift pin 114
presses the pin engagement end 130a, causing the entire rotating lever 130 to rotate counterclockwise around the shaft 131. Additionally, the steering lock device 1 is connected to the connecting end 130b.

The other end of 40 is connected.

The rotating lever 130 swings around the shaft 131 as a force is applied to 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.
It reaches the inside of the engagement end 130a of the pivot lever 130.

When the shift lever 110 is shifted to a position other than the parking position in this position, the rotation of the shift lever 110 causes the shift pin 114 to move toward the engagement end 13 of the rotation lever 130.

At the connecting end 130b, the cable 140 is pulled to the left in the figure. At the same time, the gap 122 on the opening 121 side, which had been closed by the engaging end 130a, is opened and one gap 122 is opened.
The shift pin 114 moves toward another shift position.

That is, by rotating the one-turn lever 130, the cable 140
is tensed. When the shift pin 114 is disengaged from the engagement end 130a of the rotary lever 130 due to the movement of the shift lever 110, the rotary lever 130 is held in an inclined state. When the shift lever 110 is returned to the parking position P, the shift pin 1.14 rotates the rotary lever 130 clockwise, so that the rotary lever 130 changes from the state shown in FIG. 20 to the state shown in FIG. 18. be returned. When the shift lever 110 moves from the parking position P to another position, the cable 140 to which a tensile force is applied is in a pull state. Conversely, the shift lever 110 is in the parking position [P
A compressive force is applied to the cable 140 as it is returned to the

As shown in FIGS. 1 and 4, a stopper portion 40 is provided on the outer peripheral surface of the rotating member 23. As shown in FIGS. Further, as shown in FIG. 4, the stopper portion 40 has a first stopper surface 40a and a second stopper surface 40b formed substantially perpendicular to the first stopper surface 40a. As shown in FIG. 1, the frame 11 has a block position (FIG. 6A) that prevents movement of the shift lever 110, as shown in FIG.
and a release position that allows movement of the shift lever 110 (
A second slider 50 is provided, which moves between FIG. 6D). Further, the second slider 50 is the first slider 4
1, and an arm part 52 that is provided so as to be able to engage with the first and second stopper surfaces 40a and 40b of the stopper part 40. One end of the driven part 51 contacts the cam surface 42 of the first slider 41, and the other end contacts the spring 4.

As shown in FIG. 6B, when the key cylinder 16 is in the ACC position and the second slider 50 is in the blocking position, the second slider 50 is attached to the radial surface 35 of the latch member 31. The contact prevents the second slider 50 from moving to the release position. Further, as shown in the sixth diagram, the latch member 31 is configured so that the key cylinder 16 is
When the second slider 50 is in the C position and the second slider 50 is in the release position, the second slider 50 contacts the inclined surface of the latch member 31, and the latch member 31 moves radially inward against the elastic force of the elastic member. Then, the second slider 50 is allowed to move to the blocking position.

In the above configuration, the latch member 31 is disposed within the hole 30 of the rotation member 23 and is biased toward the outside of the hole 30 by the lever spring 32 . The key cylinder 16 is in the locked position (Fig. 6A)
) to the ACC position (FIG. 6B), the radial surface 35 of the latch member 31 prevents movement of the second slider 5° in the blocking position to the release position. Therefore, the cam surface 42 of the first slider 41 contacts one end of the driven portion 51, the arm portion 52 contacts the first stopper surface 40a, and the second slider 50 is moved from the blocking position to the release position. This prevents the first slider 41 from moving from the initial position to the operating position. The shift lever 110 is held at the parking position, and the output shaft of the transmission remains mechanically fixed. -Dan, A
After the key cylinder 16 is rotated from the CC position (FIG. 6B) to the ON position N (FIG. 6C), the arm portion 52 comes off the radial surface 35 of the latch member 31, so the shift lever
110 can be moved from the parked position to other positions. At this time, the second slider 5o is moved from the blocking position to the release position by the inclined surface 41c of the first slider 41 against the elasticity of the spring 43. Also, regardless of the position of the shift lever 110, the key cylinder 16 in the on position is immediately switched to the ACC position,
It is possible to stop the engine. Furthermore, as shown in Figure 6, when the key cylinder 16 is rotated to the ACC position and the second slider 50 is at the release position, the second slider 50 hits the second stopper surface 40b of the stopper portion 4o. come into contact with

Therefore, the second slider 50 prevents the key cylinder 16 from rotating, thereby preventing the key cylinder 16 from moving to the lock position. Therefore, the driver can be made aware of returning the shift lever 110 to the parking position. At this time, if the shift lever 110 is moved to the parking position.

The first slider 41 is returned from the operating position to the initial position as shown in FIGS. 8 to 10. Therefore, the second slider 50 moves from the release position shown in FIG. 7A to the blocking position shown in FIG. 7 due to the elasticity of the spring 43. At this time, the arm portion 52 of the second slider 50 comes into contact with the inclined surface 36 of the latch member 31 (FIG. 7B) L, as shown in FIG. The latch member 31 is moved radially inward against the elasticity of the spring 32, allowing the second slider 50 to move along the inclined surface 36, so that the second slider 50 is moved to the block position shown in Figure 7. Move to.

In this way, the shift lever 110 can be smoothly returned to the parking position.

In the above configuration, the latch member 31 is disposed within the hole 30 of the rotation member 23 and is biased toward the outside of the hole 30 by the lever spring 32 . The key cylinder 16 is in the locked position N (Fig. 6A)
) to the ACC position II (FIG. 6B), the radial surface 35 of the latch member 31 prevents the second slider 50 in the blocking position from moving to the release position. Therefore, since the shift lever 110 is held at the parking position, the vehicle does not move due to its own gravity even on a sloped road. One end, ACC position (Fig. 6B
) to the on position (FIG. 6C), the shift lever 110 can be moved from the parking position to any other position.

Further, in the embodiment of the present invention, if the shift lever 110 from the parking position is moved to another position by electrical means or mechanical means only when the brake pedal is depressed, safety at the time of starting the engine can be improved. It is understood that it is possible to improve

In this case, the slider in the blocking position can only be moved to the release position when the pre-pedal is depressed.

Various modifications can be made to the above-described embodiments of the invention. For example, as shown in FIG. 7, a hole 151 formed in the second slider 50 is provided with a spring 152 and a pin 152 as a stop portion biased outwardly by the spring 152 as a one-way movement restricting means. It will be done. In FIG. 7, parts that are the same as those shown in other figures are designated by the same reference numerals, and explanations thereof will be omitted. The additional stopper section 54 is formed as a cam surface on the rotating member 23, and the first stopper surface 40a of the stopper section 40
It has a radial surface 54a that forms substantially the same plane as the radial surface 54a, and an inclined surface 54b provided on the back side of the radial surface 54a. When the key cylinder 16 is in the ACC position and the second slider 50 is in the blocking position, the pin 153a abuts against the radial surface 54a of the additional stopper portion 54 to prevent the second slider 50 from moving to the release position. do. Therefore, movement of the second slider 50 from the blocking position to the release position is prevented. Further, when the key cylinder 16 is in the ACC position and the second slider 50 is moved from the release position to the block position, the pin 153 elastically overcomes the inclined surface 54b of the additional stopper portion 54 and moves to the block position. Therefore, the second slider 50 is smoothly moved from the release position to the block position.

Further modifications to embodiments of the invention are possible.

(4) Additional stopper portion 5 integrated with latch member 31
It is also possible to form 4 and to elastically protrude from the hole of the rotation member 23 or the key cylinder 16 by means of a spring.

(5) Instead of the pin 153, an elastic piece of synthetic resin or metal may be provided on the second slider 5o, either integrally or separately, and engaged with the stopper part 40 and the additional stopper part 54.

As mentioned above, the steering lock device according to the present invention can prevent the shift lever from moving when the key is rotated from the lock position to the ACC position. is securely fixed. Therefore, movement of the vehicle due to movement of the shift lever from the lock position to the ACC position is prevented, and safety during riding can be ensured.
