Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a vehicle locking device for a driver's seat.

(Prior art) Japanese Patent Publication No. 48-7135, which is publicly known, discloses a key cylinder that locks the lock in the locked position, unlocks the lock in the unlocked position, and pulls out the key in the neutral position, and a locking button that uses the key cylinder and the locking button. The door lock device is configured to move the locking lever of the door lock by moving the locking lever of the door lock, and includes a switch that is connected to the key cylinder and locks, unlocks, and takes a neutral position at each position of the key cylinder, and a switch that locks and unlocks the door lock device. a servo motor connected to the locking lever for moving the locking lever to either of the two positions;
When the key cylinder is operated from the neutral position, the switch is activated and the servo motor displaces the locking lever to a locked or unlocked position;
Conversely, when the key cylinder is operated from the locked or unlocked position to the neutral position, the locking lever is left as is, and the connection between the key cylinder, the switch, and the locking lever operates so as to move only the switch to the neutral position. An automatic door lock device is described comprising means.

(Problems to be Solved by the Invention) The above-mentioned known example is a door lock device that includes a key cylinder that has locking, unlocking, and neutral positions, and a locking lever of a door lock that is moved by the key cylinder and locking button. It was invented for a door lock device for a driver's seat.

However, although it is a door lock device for the driver's seat, it has a lock lever that can take both positions to lock and unlock the door lock device, and a lock lever that is connected to the lock lever to move the lock lever to either of the two positions. However, using a servo motor to move the locking lever of the door lock device itself for the driver's seat is troublesome and expensive. The locking lever of the driver's door lock device can be moved simply by operating the key or the sill knob.

Further, in a known example, when the key cylinder is operated from the locked or unlocked position to the neutral position, the locking lever is left as is and only the switch is moved to the neutral position. Although an automatic door lock device comprising a connecting means between the two has been invented, no device has been invented to prevent the rear seat door or passenger seat door from being unlocked even if the door knob attached to the driver's seat door is operated. However, children may be placed in the back seat or passenger seat of a vehicle, so
It is necessary to devise a way to prevent the rear seat and passenger door from being unlocked even if the driver's door is unlocked by operating the sill knob attached to the driver's door.

(Means for Solving the Problems) Therefore, the present invention provides a lock lever 13 that is supported by a shaft 12 and rotates around the shaft 12 between a locked position and an unlocked position, and one end of the lock lever 13. A lock rod 14 is connected to the lock knob and can be moved up and down by manual locking/unlocking operation of the lock knob to displace the lock lever 13 between a locked position and an unlocked position.
, an arc elongated hole 15 centered on the shaft 12 formed at the other end of the lock lever 13;
A switch lever 17 whose base is pivotally supported on 2, and a tip of the switch lever 17 and the lock lever 13
The switch lever 17 is engaged with both the circular arc elongated hole 15 and moved up and down by manual locking/unlocking operation of the key.
and the key rod 16 which displaces the lock lever 13 between the locked position and the unlocked position, and when the switch lever 17 is turned, the solenoid or motor of the lock device other than the driver's seat is energized, It consists of a switch 19 for locking and unlocking the lock device, and the lock lever 13;
The silno rod 14 and the circular arc elongated hole 15
, the switch lever 17, and the switch 1
9 means that even if the lock lever 13 from the locked position is moved to the unlocked position by unlocking the cylinder block 14, the switch lever 17 does not rotate and the switch 19 closes all doors other than the driver's seat. The vehicle locking device for the driver's seat is connected in a manner that prevents the vehicle from being unlocked.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. The present invention shows a lock device attached to a driver's seat,
Reference numeral 1 designates a body of a locking device made of synthetic resin. A recess 4 is formed on the front side of the body 1, and a latch 2 and a latch 3 are mounted within the recess 4.

The latch 2 is rotatably attached to the body 1 via a shaft 5, and has an engagement groove 7 in which the striker 6 engages, a half engagement step 8 in which the latch 3 engages, and a full engagement groove on its outer peripheral surface. A joint portion 9 is formed respectively. Reference numeral 10 denotes a shaft that connects the ratchet 3 to the body 1. In FIGS. 1 and 2, when the ratchet 3 rotates clockwise, it disengages from the half engagement step 8 or the full engagement step 9. and open the door.

The shaft 10 projects to the back side of the body 1, and a release lever 11 is fixed thereto. That is, a ratchet 3 and a release lever 11 are each fixed to the shaft 10, and when the release lever 11 rotates, the ratchet 3 rotates.

A lock lever 13 is pivotally attached to a position below the release lever 11 by a shaft 12. The lock lever 13 protrudes left and right from the shaft 12, and a sill rod 14 is connected to one end (right end) of the lock lever 13. The other end (left end) of the lock lever 13 is provided with an arcuate elongated hole 15 centered on the shaft 12. The lower end of a key rod 16, which moves up and down when a key is operated, is engaged with the arcuate elongated hole 15. The lower end of the key rod 16 also engages with the tip of a switch lever 17 rotatably fixed to the shaft 12.

A play hole 18 is formed at an intermediate position in the length direction of the switch lever 17, and the switch 19 is inserted into the play hole 18.
The tip of the switch rod 20 is engaged with the pin 21. The switch 19 is connected to a solenoid (or motor) of a locking device for another door, and when the key rod 16 is moved up and down by key operation, the switch 19 is turned on and off to lock and unlock other doors.

The lock lever 13 is formed so as to be freely displaceable between a lock position and an unlock position, similar to a known lever. A protrusion 22 is provided in the center of the lock lever 13 and protrudes upward at a right angle.
is provided with a pin 25 that engages with a vertical elongated hole 24 formed at the lower end of an operating rod 23 that moves up and down. The upper end of the operating rod 23 is connected to the open lever 2 by a shaft 26.
It is pivoted to the end of 9. Open lever 29
The left and right intermediate positions are pivoted by a shaft 30.

When the lock lever 13 is rotated to the unlock position (the state shown in FIGS. 5 and 6), the pin 25 pushes and moves the vertical elongated hole 24 at the lower end of the operating rod 23 to the left, and the release lever 11 is moved. The pressing part 28 of the operating rod 23 comes to face the upper part of the projection 27. In this state, that is, with the pressing part 28 facing the upper part of the protrusion 27, when the door opening handles inside and outside the door are operated to open the door and the opening lever 29 is rotated to the left against the elasticity of the spring 31, the opening lever 29
The operating rod 23, which is pivotally attached to the end of
1 is rotated, the shaft 10 fixed to the release lever 11 rotates, and the latch 3 fixed to the shaft 10 rotates clockwise in FIG. 2 to disengage from the latch 2, releasing the full lock and opening the door.

When the lock lever 13 is rotated to the lock position (the state shown in FIGS. 3 and 4), the pin 25 pushes the vertical elongated hole 24 at the lower end of the operating rod 23 to the right and moves the lock lever 13 to the lock position. From the upper position of the protrusion 27, the pressing portion 28 of the operating rod 23 is removed to the right. In this state, that is, with the pressing part 28 removed from the upper part of the protrusion 27, open the door handles inside and outside the door to open the door and rotate the open lever 29 to the left against the elasticity of the spring 31. Even if the operating rod 23, which is pivotally attached to the end of the door, is lowered, the pressing part 28 is vibrating and cannot rotate the release lever 11, and the ratchet 3 cannot be rotated, so the door cannot be opened. do not have.

As shown in FIG.
When the switch 6 is set to the locked position, the lock lever 13 and the switch lever 17 are set to the locked position, and the switch 19 is turned on in the locked state. Since the key cannot be pulled out in the locked position, it is returned to the neutral position, but even when the key is returned to the neutral position, the lock lever 13 remains in the locked position due to the arcuate elongated hole 15. Further, when the key rod 16 is moved to the unlocked position (FIG. 5) by operating a key, the lock lever 13 and the switch lever 17 are moved to the unlocked position, and the switch 19 is turned on in the unlocked state. Since the key cannot be pulled out in the unlocked position, it is returned to the neutral position, but even when the key is returned to the neutral position, the lock lever 13 remains in the unlocked position due to the arcuate elongated hole 15.

Therefore, as mentioned above, the locking device attached to the driver's door locks and unlocks the driver's door when the key is inserted into the key cylinder attached to the driver's door and the lock is operated. Doors other than the driver's door are also locked and unlocked at the same time, so even when operating the sill knob attached to the driver's door, doors other than the driver's door may be locked and unlocked, such as when a child is in the rear seat. Although there were some problems, the present invention
The relationship between the lock lever 13, the switch lever 17, the switch 19, and the circular arc elongated hole 15 is other than that described above. Even if the position is changed, the switch lever 17 does not move and the switch 19 does not turn on or off, so the rear seat door remains locked.

(effect) Next, we will discuss the effect.

The locking device of the present invention is installed on the driver's door.

When the key is inserted into the key cylinder of the locked driver's seat door and the key is operated from the locked position to the unlocked position beyond the neutral position, the key rod 16 is lowered, as shown in FIGS. 3 to 5.

That is, the key rod 16 in FIG.
5, collides with the inner wall below, and descends further. At the same time, the switch lever 17
The switch 19 is turned on through the switch rod 20 from ON to OFF to ON.

At the same time, the protrusion 22 is rotated counterclockwise, and the pin 25 fixed to the protrusion 22 presses the side wall of the upper and lower long holes 24 to the left, so the operating rod 23 rotates to the left about the shaft 26, and the operating rod 23 The pressing portion 28, which is a part of the projection 27, is placed directly above the protrusion 27. In this state,
When the door outside handle is operated to open the door, the open lever 29 rotates counterclockwise around the shaft 30.
The operating rod 23, which is rotatably attached to the tip of the open lever 29 by a shaft 26, is lowered, and its pressing portion 28 pushes the protrusion 27 downward. Therefore, release lever 1
Since the latch 1 rotates around the shaft 10, the latch 3 fixed to the shaft 10 rotates, and the latch 3 and latch 2 are disengaged and the striker 6 is moved from the engagement groove 7. Get out and open the door.

At the same time, the pin 21 engaged with the play hole 18 of the switch lever 17 moves downward, so the switch rod 20 moves downward, energizing the solenoid of the door other than the driver's seat via the switch 19, and Move the lock knobs up all at once to release the lock.

When you get into the car and start driving, the switches are locked all at once, as is well known, and the locking lever 13 of the driver's seat locking device also rotates clockwise as shown in Figure 3. , and the upper and lower elongated holes 2 are opened by the action of the pin 25 of the protrusion 22.
4 to the right so that the pressing part 28 is removed from the protrusion 27.

In this state, even if the open lever 29 is rotated to the left and the operating rod 23 is moved downward as shown in FIG. 4, the pressing part 28 does not come into contact with the protrusion 27, and therefore the pressing part 28 is ineffective. , the door cannot be opened and remains locked.

Therefore, the state indicated by the phantom line 16 in FIG. 3 is the state in which the key is returned to the neutral position and pulled out after the lock has been locked. Even if the lock lever 16 is rotated to the unlocked position, the key rod 16 and the lock lever 13 are connected through the circular arc elongated hole 15, so even if the lock lever 13 is rotated to the left, it will not rotate to the switch lever 17.
Only the lock lever 13 rotates to be in the state shown in FIG. 6, and in this case, the switch lever 17 does not rotate, so the switch 19 does not operate and other doors other than the driver's seat are not unlocked.

(Effects) The conventionally known device described in Japanese Patent Publication No. 48-7135 is a door lock device for the driver's seat, but the locking lever, which has both locking and unlocking positions, is moved by a servo motor. Because of the structure, there are problems in that the structure is troublesome and expensive.

Furthermore, in the known example, when the key cylinder is operated from the locked or unlocked position to the neutral position, the locking lever is left as is and only the switch is moved to the neutral position. Nothing has been done to prevent the rear seats or passenger door from being unlocked even if you operate the front door knob. However, since children are sometimes carried in the rear seat or passenger seat of a vehicle, it is necessary to devise a way to prevent the rear seat or passenger door from being unlocked even if the driver's seat door lock knob is unlocked. .

However, the present invention provides a lock lever 13 that is supported by a shaft 12 and is rotatably displaced around the shaft 12 between a locked position and an unlocked position, and
a lock rod 14 connected to one end and capable of moving up and down by manual locking/unlocking of the lock knob to displace the lock lever 13 between a locked position and an unlocked position;
, an arc elongated hole 15 centered on the shaft 12 formed at the other end of the lock lever 13;
A switch lever 17 whose base is pivotally supported on 2, and a tip of the switch lever 17 and the lock lever 13
The switch lever 17 is engaged with both the circular arc elongated hole 15 and moved up and down by manual locking/unlocking operation of the key.
and a key rod 16 that displaces the lock lever 13 between the locked position and the unlocked position, and when the switch lever 17 is turned, the solenoid or motor of the lock device other than the driver's seat is energized, It consists of a switch 19 for locking and unlocking the lock device, and the lock lever 13;
The silno rod 14 and the circular arc elongated hole 15
, the switch lever 17, and the switch 1
9 means that even if the lock lever 13 from the locked position is moved to the unlocked position by unlocking the cylinder block 14, the switch lever 17 does not rotate and the switch 19 closes all doors other than the driver's seat. Since the vehicle locking device for the driver's seat is linked in a manner that prevents it from being unlocked, (a) the lock lever 13 of the locking device for the driver's seat can be moved between the locked position and the unlocked position by manual operation of the seal knob or manual locking/unlocking operation of the key. Since the locking lever is rotated in between, the structure is simpler and cheaper than the known structure in which the locking lever is moved by a servo motor.

(b) Since the switch 19 is provided to lock and unlock the locking devices other than the driver's seat by energizing the solenoids or motors of the locking devices other than the driver's seat, the locking devices other than the driver's seat can be locked and unlocked in conjunction with each other.

C. The lock lever 13, the sill rod 14, the circular arc elongated hole 15, the switch lever 17, and the switch 19 operate to unlock the sill rod 14 and move the lock lever 13 from the locked position to the unlocked position. Since the switch lever 17 does not rotate even if it is displaced, it is safe when a child is placed in the passenger seat or rear seat.

This effect is achieved.
