2. Description of the Related Art Conventionally, in a gate type AT shift lever,
For example, a shift lock device is provided so that the shift lever can perform a select operation from the parking position to the parking release position only when the brake pedal is depressed, such as when starting the vehicle (for example, Japanese Patent Laid-Open No. Hei 4-30).
No. 7162). However, in general, gated AT
In the shift lever, it is desirable that not only the selection operation from the parking position to the parking release position but also the selection operation from the neutral position during traveling to the reverse position is prohibited.

Accordingly, the applicant of the present invention has proposed a shift lock in which a single drive mechanism can inhibit a select operation from a parking position to a parking release position and a select operation from a neutral position to a reverse preparation position under predetermined conditions. The device is proposed. This shift lock device is, for example, as shown in FIG.
1 and a first lock member 103 that rotates around a fulcrum 102 and a link 104
And a second lock member 106 that rotates around the fulcrum 105.

In this shift lock device, normally, the electromagnetic solenoid 101 is not energized, and as shown in FIG. 14, the first lock member 103 protrudes into the movement path 108 of the shift lever 107 at the parking release position P1. The 2 lock member 106 protrudes to the movement path 108 of the shift lever 107 at the reverse preparation position R1. In such a state, even if the driver attempts to select the shift lever 107 from the parking position P to the parking release position P1, one side of the shift lever 107 is locked by the first lock member 10.
3 and the force applied to the first lock member 103 is supported by the inner wall 109 of the shift lever housing. Therefore, the shift lever 107 is locked at the parking position P. Further, even if the driver erroneously performs a select operation from the neutral position N to the reverse position R during traveling, one side of the shift lever 107 collides with the second lock member 106 at the reverse preparation position R1 in the middle thereof. Since the force applied to the second lock member 106 is supported by the inner wall 109 of the shift lever housing, the selection operation to the reverse position R is prevented. However, in such a state, when a selection operation is performed from the reverse position R to the parking release position P1, or when the reverse position R is shifted to the reverse preparation position R1.
When performing the select operation to 1, the shift lever 10
The first and second lock members 103 and 106 abutting on the swing of the pivot 7 rotate around the fulcrums 102 and 105. Therefore, the swing of the shift lever 107 is allowed, and the select operation to the parking release position P1 and the reverse preparation position R1 is enabled. At this time, the first and second
The rotation of the lock members 103 and 106 is performed by the electromagnetic solenoid 10.
1 and is absorbed by the urging means 110 provided in the apparatus.

When the shift lock device detects that the driver starts the engine with a key and that the brake pedal is depressed, the electromagnetic solenoid 1
01 is energized. As a result, as shown in FIG. 15, the first lock member 103 rotates around the fulcrum 102 and retracts from the movement path 108 of the shift lever 107. When the driver performs a select operation from the parking position P to the parking release position P1, the first lock member 103 does not contact the shift lever 107, and the select operation can be continued to the reverse position R side. .

When a brake operation is performed during traveling and the vehicle speed falls below a predetermined speed, the electromagnetic solenoid 101 is similarly energized. As a result, as shown in FIG. 15, the second lock member 106 rotates around the fulcrum 105 and
07 withdraws from the moving route 108. When the driver performs a select operation from the neutral position N to the reverse preparation position R1, the second lock member 106 is attached to the shift lever 107.
Are not in contact with each other, and the selection operation toward the reverse position R can be continued.

[0007]

The above-mentioned conventional shift lock device has the advantage that the select operation can be locked at two locations by using a single drive mechanism, but has a lock member at each location. In addition, since the lock members are connected via the link, the number of parts is large, and as a result, the number of assembly steps when assembling the shift lock device increases. In addition, rattling occurs due to play of the connected lock member and link,
This may cause abnormal noise during operation of the shift lock device.

The present invention has been made in view of such circumstances, and although the select operation can be locked at two or more locations by a single drive mechanism, the number of parts is reduced and assembly is simplified.

The control of the electromagnetic solenoid 23 is performed based on a signal indicating the operation state of the ignition switch of the vehicle, a signal indicating that the brake pedal of the vehicle is depressed, and a vehicle speed signal. When the electromagnetic solenoid 23 is energized, the solenoid shaft 23a retracts toward the main body, and rotates the lock member 22 around the support shaft 21. In the present embodiment, the lock member 22 rotates clockwise in FIG. A spring 25 as an urging means is provided on the solenoid shaft 23a, and the spring 25 locks the connector 24 sliding on the solenoid shaft 23a to a maximum extent by the locking member 22.

As shown in FIGS. 1 and 4, the lock member 22 is arranged so that, when the shift lever 10 is in the parking position P, the lock member 22 faces the distal end surface of the engagement projection 20 in the operating position. A first engagement surface 29 extending along the rotation direction, and a first engagement surface 29 extending along the rotation direction of the lock member 22 so as to face the distal end surface of the engagement protrusion 20 when the shift lever 10 is at the neutral position N. 2 engagement surface 30. When the shift lever 10 attempts to enter the parking release position P1 from the parking position P, the first engagement surface 2
9 abuts against the distal end surface of the engagement protrusion 20, and the selection operation from the parking position P along the first direction A to the parking release position P1 is prevented. When the shift lever 10 attempts to enter the reverse preparation position R1 from the neutral position N, the second engagement surface 30 abuts on the distal end surface of the engagement protrusion 20, and the shift lever 10 reverses from the neutral position N along the first direction A. The selection operation to the preparation position R1 is blocked. In this case, the force applied to the lock member 22 from the shift lever 10 is supported by the inner wall of the housing 13 as shown in FIG. When the lock member 22 rotates to the non-operation position, even if the shift lever 10 is swung in the first direction A from the parking position P and the neutral position N, the distal end surface of the engagement protrusion 20 contacts the lock member 22. And a free select operation can be performed.

The lock member 22 is provided with a reverse position release groove 31 that allows the engagement protrusion 20 to enter at the operation position and allows a select operation from the reverse position R along the first direction A. By the reverse position release groove 31, the engagement protrusion 20 which should otherwise collide with the first engagement surface 29 passes through the reverse position release groove 31, so that the shift lever 10 can swing in the first direction A. Becomes

On both sides of the reverse position release groove 31, a parking position establishing sliding surface 32 and a neutral position establishing sliding surface 33 are formed continuously. When the shift lever 10 is operated in the second direction B toward the parking release position P1, the peripheral surface of the engagement protrusion 20 slides on the parking position establishment sliding surface 32. Due to this sliding, a pressing force is applied to the lock member 22, and the lock member 22 rotates to the non-operation position side. Further, when the shift lever 10 is operated to select the reverse preparation position R1 in the second direction B, the peripheral surface of the engagement projection 20 slides on the neutral position establishment sliding surface 33 in the same manner. Lock member 22
Rotates toward the inoperative position. Therefore, the lock member 2
At the time of the operation 2, the select operation to the parking leaving position P1 along the first direction A cannot be performed, but the selecting operation to the parking leaving position P1 along the second direction B is allowed. On the other hand, the selection operation to the reverse preparation position R1 along the first direction A cannot be performed, but the selection operation to the reverse preparation position R1 along the second direction B is allowed.

Next, the operation of the first embodiment will be described with reference to FIGS. It is assumed that the shift lever 10 is at the parking position P before the driving of the vehicle starts. The engagement protrusion is
As shown in FIGS. 5A and 6, the lock member 22 faces the first engagement surface 29. When the driver keeps the ignition switch turned off or turned on but does not depress the brake pedal, the electromagnetic solenoid 23 is not energized. As a result, the shift lever 10 is locked at the parking position P due to the collision between the first engagement surface 29 and the engagement protrusion 20, and cannot enter the parking release position P1.

When the driver turns on the ignition switch and depresses the brake pedal, a signal indicating the operation state of the ignition switch and a signal indicating the operation state of the brake pedal are supplied to the electromagnetic solenoid 23.
The electromagnetic solenoid 23 is energized. As shown in FIG. 5B, the solenoid shaft 23a retracts by the stroke S, the lock member 22 rotates to the non-operation position, and the engagement protrusion 2
The contact between the first engagement surface 29 and the first engagement surface 29 is avoided. Therefore, the shift lever 10 can perform a select operation subsequent to the parking release position P1 from the parking release position P1.

When the brake pedal is not depressed, the electromagnetic solenoid 23 is not energized and the lock member 22 is in the operating position. Shift lever 1 in reverse position R
0 faces the reverse position release groove 31 as shown in FIGS. 5 (A) and 7. Even if the driver selects the shift lever 10 to the parking release position along the first direction A, the engagement projection 20 enters the reverse position release groove 31 as shown in FIG. can do. In FIG. 5A, when the shift lever 10 is subsequently operated in the second direction B, the engagement protrusion 20 slides on the parking position establishment sliding surface 32. Lock member 2
2 is pressed downward against the urging force of the spring 25, and the parking separation position P1 is established. When the shift lever 10 is selectively operated from the parking release position P1 to the parking position P along the first direction A, the engagement projection 20 is disengaged from the parking position establishment sliding surface 32.

Similarly, when the electromagnetic lever 23 is not energized and the shift lever 10 is selectively operated from the reverse position R in the second direction B to the neutral position N, the engagement projection 20 slides to establish the neutral position. Face 3
3 slide on. The lock member 22 is pressed downward against the urging force of the spring 25, and the reverse preparation position R1 is established. When the shift lever 10 is operated in the first direction A from this state, the engagement projection 20 is disengaged from the neutral position establishment sliding surface 33. A neutral position N is established.

Shift lever 1 in neutral position N
At 0, the engagement projection 20 faces the second engagement surface 30 as shown in FIGS. As a result, the collision between the second engagement surface 30 and the engagement protrusion 20 causes the shift lever 1 to move.
0 is locked to the neutral position N and cannot enter the reverse preparation position R1. Electromagnetic solenoid 2
As long as 3 is not energized, the lock member 22 maintains the operating position, and can freely establish the neutral position N, the drive travel position D, the third gear travel position D3, the second gear travel position D2, and the low gear position L.

According to the first embodiment, the single lock member 22 prevents the selection operation from the parking position P to the parking release position P1 and the selection operation from the neutral position N to the reverse preparation position R1. Can be achieved, the number of parts can be reduced even though the select operation can be locked at two or more places by a single drive mechanism, and as a result, the number of assembling steps when assembling the shift lock device is reduced. be able to. Further, unlike the related art, rattling due to play of the lock member and the link does not occur, and generation of abnormal noise during operation of the shift lock device can be prevented.

FIG. 9 shows a shift lock device according to a second embodiment of the present invention. In the second embodiment, the lock member 22 has a third surface that extends along the rotation direction of the lock member 22 so as to face the distal end surface of the engagement protrusion 20 when the shift lever 10 is at the drive travel position D. It is characterized in that an engagement surface 40 is provided. Other configurations are the same as those of the first
Since the configuration is the same as that of the embodiment, the same configuration is denoted by the same reference numeral, and the detailed description is omitted.

In the second embodiment, the shift lever 1
When the drive travel position D is to enter the low gear preparation position L1 from the drive travel position D, the third engagement surface 40 abuts on the distal end surface of the engagement projection 20 and the drive travel position D along the first direction A
The selection operation from the low gear preparation position L1 to the low gear preparation position L1 is blocked. According to this configuration, in addition to the prevention of the select operation in the first embodiment, the select operation from the drive traveling position D to the low gear position L cannot be performed until the brake pedal is depressed and decelerated. .
The drive travel position D may be the second gear travel position D2 or the like as long as it is a travel position adjacent to the low gear position L.

The lock member 22 is provided with a drive running position establishing slide surface 41. Shift lever 10

By the reverse position release groove 59, the engagement projection 56, which should otherwise collide with the lock member 51, passes through the reverse position release groove 59, so that the shift lever 55 can swing from the reverse position R.

As in the above-described embodiment, a parking position establishing sliding surface 60 and a neutral position establishing sliding surface 61 are continuously formed on both sides of the reverse position release groove 59. When the shift lever 55 is selected from the parking release position P1 to the parking position P along the second direction B, the peripheral surface of the engagement protrusion 56 slides on the parking position establishment sliding surface 60. Due to this sliding, the lock member 51 is pushed downward against the urging force of the spring 25 (see FIG. 13B), and rotates to the inoperative position side. Further, when the shift lever 55 is operated to select the reverse preparation position R1 in the second direction B, the peripheral surface of the engagement protrusion 56 slides on the neutral position establishment sliding surface 61 in the same manner. As a result, the lock member 51 rotates to the non-operation position side.

Therefore, when the lock member 51 is operated, the select operation from the parking position P along the second direction B to the parking release position P1 cannot be performed, but on the contrary, from the parking release position P1 to the parking position P
Select operation to is allowed. Further, the selection operation from the neutral position N to the reverse preparation position R1 cannot be performed, but the selection operation from the reverse position R to the reverse preparation position R1 is permitted.

When the driver turns on the ignition switch and depresses the brake pedal in the same manner as in the above-described embodiment, a signal indicating the operation state of the ignition switch and a signal indicating the operation state of the brake pedal are provided. Is supplied to the electromagnetic solenoid 23. As a result, the electromagnetic solenoid 23 is energized, and the lock member 51 is turned downward to operate.
Select operation of the shift lever 55 is permitted.

Further, similarly to the above-described second embodiment, the lock member 51 has a third engagement surface 62 along the second direction B for preventing the second gear traveling position D2 from entering the low gear preparation position L1. Is formed. This third engagement surface 62
Are formed on the protrusion 63 in the same manner as the second engagement surface 54. Therefore, as shown in FIG. 13A, when the lock member 51 is in the operating position, when the shift lever 55 is swung from the second gear traveling position D2 to the low gear preparation position L1, the third engagement surface 62 becomes The distal end surface 56b of the engagement protrusion 56 is abutted, and the selection operation from the second gear traveling position D2 along the first direction A to the low gear preparation position L1 is prevented. On the other hand, when the vehicle speed becomes lower than or equal to the predetermined speed due to the operation of the brake pedal or the like, the electromagnetic solenoid 23 operates to rotate downward as shown in FIG. Is enabled, and the select operation from the second gear traveling position D2 to the low gear preparation position L1 is permitted.

As shown in FIG. 11, the projection 63 is
From the low gear position L to the low gear preparation position L along the direction B
A running position establishment sliding surface 64 that is an upward slope toward 1 is provided. Therefore, when the shift lever 55 is moved from the low gear position L to the low gear preparation position L1, the peripheral surface (lower surface) of the engagement projection 56 is the running position establishing sliding surface 64.
Slide on top. Due to this sliding, the lock member 51 is pushed downward against the urging force of the spring 25 (see FIG. 13B), and rotates to the inoperative position side. As a result, the selection operation from the low gear position L to the low gear preparation position L1 and further to the second gear traveling position D2 is permitted.

As described above, even when the parking position P and the parking release position P1 are arranged along the second direction B, by using the end surface of the lock member in the second direction B, the first and second positions described above are used. As in the case of the second embodiment, a single lock member can prevent the shift lever from being selected in a predetermined direction.

[0055]

As described above, the single lock member can prevent the selection operation from the parking position to the parking release position and prevent the selection operation from the neutral position to the reverse preparation position. Although the selection operation can be locked at two or more places by the drive mechanism, the number of parts is reduced, and as a result, the number of assembling steps when assembling the shift lock device can be reduced. Further, unlike the related art, rattling due to play of the lock member and the link does not occur, and generation of abnormal noise during operation of the shift lock device can be prevented.

Further, simply providing the first and second engagement surfaces on the lock member makes it possible to simply and reliably prevent the selection operation.

Further, the selection operation from the traveling position to the low gear position can be effectively prevented. As a result, the number of components can be reduced although the selection operation can be locked at three or more locations by a single drive mechanism.

Further, simply by providing the first, second and third engagement surfaces on the lock member, it is possible to simply and reliably prevent the selection operation.
