Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an improvement in a locking device for controlling locking and unlocking of a vehicle door.

BACKGROUND ART Conventionally, a device for controlling the locking and unlocking of all the doors of a vehicle is operated from outside the vehicle using a door key cylinder on the driver's seat side, as shown in FIG. The locking lever C is rotated by the key lever B which is rotated by the key link A, and the open link D of the driver's door is disengaged from the pressure receiving end F of the open lift lever E as shown in Fig. 5. When the key lever B is rotated, the key lever B is guided to the locked position, or conversely, the pressing end G of the open link D is guided to the unlocked position, that is, directly above the pressure receiving end F of the open lift lever E. When unlocking, unlock switch H is activated to unlock all other doors, and when locking, a micro switch J built in solenoid I that is linked to the rotation of locking lever C operates to unlock all other doors. A structure in which all doors are locked is known.

The locking device shown in FIG. 5 can also be operated by mechanically operating the door locking knob of the driver's door inside the vehicle and rotating the locking lever C using the locking link K. Similarly, the driver's door and all other doors can be locked or unlocked at the same time.

Problems to be Solved by the Invention In the locking device having the structure shown in FIG. Unlock the driver's door and
Even if only the driver tries to get out of the car, all doors including the passenger door are unlocked, making it impossible to unlock or lock only the driver's door, which is not only extremely inconvenient, but also requires the unlock switch H. , the addition of locking solenoids, etc. has disadvantages such as an increase in the number of parts and an increase in the space required for setting.

In view of the current situation, the present invention allows the driver's door to be locked, for example, by operating the key plate of the door key cylinder attached to the driver's door.
At the same time as unlocking, all other doors can be locked or unlocked, and by operating the locking knob attached to the driver's door, you can only unlock or lock that driver's door and lock the other doors. The object of the present invention is to provide a locking device with a relatively simple mechanism that cannot be unlocked, does not require an increase in the number of parts, requires a small installation space, and eliminates the drawbacks of the conventional devices described above.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a locking lever rotatably supported on a fixed shaft, which is connected to the locking lever by rotation in the unlocking direction. The pressing portion of the open link is rotated onto the pressure receiving end of the open lift lever to occupy the unlocked position, and the pressing portion of the open link is placed in the locking position by rotating the locking lever in the locking direction. In a locking device that is rotated outward to occupy a locked position, a pressure receiving part is protruded from the locking lever on a concentric circle close to a fixed axis, and is connected to a key link that is moved up and down by a door key cylinder. The key lever, which is rotated around a fixed axis, is formed with first and second pressing parts that face the pressure receiving part of the locking lever from both front and rear sides in the direction of rotation, and the key lever is rotated around a fixed axis. is a first position in which the first pressing part presses and rotates the pressure receiving part of the locking lever in the unlocking direction to rotate the open link to the unlocking position, and a second position in which the second pressing part is in the locking position. a second position in which the pressure receiving part of the lever is pressed and rotated in the locking direction and the open link is rotated to the locking position; and a gap exists between the first and second pressing parts on both sides of the pressure receiving part; First located,
3 with the neutral position which is intermediate between the second two positions.
The key lever has a solenoid operating solenoid that operates to unlock the locking device of another door in the first position and to lock the locking device of the other door in the second position. When a single switch is provided and the open link is in the locking position and the key lever is in the neutral position, there is a first free movement between the second pressing part of the key lever and the pressure receiving part of the locking lever. A gap is formed, and the length of the first free gap is such that the locking knob on the driver's door side provides a rotation angle that allows the locking lever to rotate the open link to the unlocked position. is selected, and when the open link is in the unlocked position and the key lever is returned to the neutral position, there is a second floating gap between the first pressing part of the key lever and the pressure receiving part of the locking lever. is formed, and the length of the second swing gap is selected to be such that the locking knob on the driver's door side provides a rotation angle that allows the locking lever to rotate the open link to the locked position. The structure is as follows.

Function In this invention, for example, when the door key cylinder of the driver's door is used to lock or unlock that door, other doors are also locked or unlocked at the same time by the action of a single switch. When the locking lever attached to the driver's door is operated in the locked state, only the driver's door can be unlocked or locked, regardless of other doors, and only a single switch is required. The space required for installation can be made relatively small.

Embodiment The first figure is a front view of an example of the embodiment applied to the driver's door, with the lock device in the locked state, and the key link 2 with the door key cylinder (not shown).
The key lever 1 operated via the key lever 1 is in the neutral position.

In FIG. 1, the key link 2 is moved up and down in the directions of arrows L and M by rotating the key plate of the door key cylinder (not shown).
A key lever 1 connected to one end pivots around a fixed shaft 3 fixed to a door panel, etc. in the direction of an arrow N,
It is rotated back and forth in the O direction.

A locking lever 4 is also supported on the fixed shaft 3 so as to be rotatable in the directions of arrows N and O, and when the key lever 1 is rotated in the direction of arrow N,
When the first pressing part 5 of the key lever 1 presses the pressure receiving part 6, the key lever 1 is rotated in the direction of the arrow N, and when the key lever 1 is rotated in the direction of the arrow O, the key lever 1
When the pressure receiving part 6 is pressed by the second pressing part 7, it is rotated in the direction of the arrow O.

In the locking lever 4 described above, the pin 9 of the upwardly extending projecting arm 8 is inserted into the long groove hole 1 of the open link 10.
When the locking lever 4 is rotated in the direction of arrow N, the open link 10 is rotated in the direction of arrow P about the shaft 12, and the locking lever 4 is rotated in the direction of arrow O. The structure is such that the open link 10 can be rotated in the direction of arrow Q by the rotation.

The above-mentioned rotation of the locking lever 4 in the direction of arrow N is rotation in the unlocking direction, and rotation in the direction of arrow O is rotation in the locking direction.

When the locking lever 4 is rotated in the unlocking direction in the direction of arrow N and the open link 10 is rotated in the direction of arrow P, the pressing part 13 of the open link 10 is placed on the pressure receiving end 15 of the open lift lever 14. It is rotated to occupy the unlocked position.
In this state, if the open link 10 is moved downward by the doorknob, the door is opened by the open lift lever 14. This situation is shown in FIG.
When the locking lever 4 is rotated in the direction of arrow O from the state shown in FIG. 2, the pressing portion 13 of the open link 10 moves from the state shown in FIG. 2 to the locked position shown in FIG. is made to occupy a position outside the pressure receiving end 15 of.

A switch operating lever 1 is connected to the lower part of the key lever 1 through a pin 17 that engages with a horizontally elongated hole 16.
8 is engaged so that the switch 19 can be turned ON-OFF-ON according to the rotation of the key lever 1.

This switch 19 is inserted into a solenoid circuit of a device that controls the locking and unlocking of all the locking devices outside the driver's door to which the above-mentioned locking device is attached. When the key lever 1 rotates the locking lever 4 in the locking direction, the locking device of the other door is activated to lock, and when the key lever 1 rotates the locking lever 4 in the unlocking direction, the locking device of the other door is activated to unlock.

The aforementioned locking lever 4 also includes a locking link 20 coupled to a locking knob (not shown) attached to the driver's door.
are coupled, and the locking lever 4 is rotated in the unlocking direction shown by the arrow N or the locking direction shown by the arrow O, independently of the operation by the key lever 1.

In FIG. 1, the open link 10 is in the locked position and the key lever 1 is in the neutral position. The dimensions of each member are set so that a first floating gap X is formed, and the length of this floating gap X is determined by the locking link 20 connected to the locking knob on the driver's door side. When the lever 4 is rotated in the unlocking direction in the direction of the arrow N, the locking lever 4 has a rotation angle sufficient to rotate the pressing part 13 of the open link 10 to the unlocked position above the pressure receiving end 15 of the open lift lever 14. Therefore, the above-mentioned rotation of the locking lever 4 has no effect on the key lever 1, and the other doors are kept locked.

Now, when the key link 2 is moved forward in the direction shown by the arrow L by the door key cylinder (not shown) in the locked state shown in FIG.
The key lever 1 rotates in the direction of arrow N around a fixed shaft 3, and when its first pressing portion 5 comes into contact with the pressure receiving portion 6 of the locking lever 4, the key lever 1 presses the locking lever 4. The key lever 1 is rotated in the direction of arrow N, which is the unlocking direction, and the key lever 1 assumes the first position.

As the locking lever 4 rotates in the unlocking direction in the direction of arrow N, the pin 9 of the protruding arm 8 presses the right side edge of the long slot 11 of the open link 10, so the open link 10 rotates in the direction of the arrow P. The pressing part 13 is moved by the open lift lever 14.
is brought to the unlocked position above the pressure receiving end 15 of the locking device, and the unlocking operation of the locking device is completed. This state is the second
This is the state shown in the figure.

When this state is reached, the switch operating lever 18, which is secured to the horizontal slot 16 of the key lever 11 with a pin 17, also moves downward, turning the switch 19 ON.
Activates the solenoid to unlock all other door locking devices.

When the above-mentioned operation is completed, the key plate of the key cylinder (not shown) is released, and the key lever 1 is returned to the neutral position shown in FIG. 1, and becomes the state shown in FIG. 3.

At this time, the dimensions of each member are set so that a second free movement gap Y is formed between the first pressing part 5 of the key lever 1 and the pressure receiving part 6 of the locking lever 4. The length of the gap Y is determined by the pressure of the open link 10 when the locking lever 4 is rotated in the locking direction in the direction of arrow O by the locking link 20 connected to the locking knob on the driver's door side (not shown). The length is such that a sufficient rotation angle can be given to the locking lever 4 to rotate the portion 13 from the pressure receiving end 15 of the open lift lever 14 to the locked position shown in FIG. 1.

Since the rotation of the locking lever 4 described above has no effect on the key lever 1, the other doors are kept unlocked.

Now, in the unlocked state shown in FIG. 3, the upward movement of the key link 2 shown by the arrow M caused by the operation of the door key cylinder (not shown) causes
When the key lever 1 is rotated in the direction shown by the arrow O, the second pressing portion 7 presses the pressure receiving portion 6 of the locking lever 4, and the locking lever 4 is rotated.
The key lever 1 is also rotated in the locking direction indicated by the arrow O, and the key lever 1 occupies the second position. This locking lever 4
When the open link 10 is rotated in the locking direction, the open link 10 is rotated in the direction of the arrow Q by the action of the projecting arm 8, pin 9, and long slot 11, and the pressing portion 13 is released from the pressure receiving end 15 of the open lift lever 14. 4, and the locking device is brought into the locked position shown in FIG.

By rotating the key lever 1 in the direction of arrow O, the switch actuating lever 18 moves upward, and the switch 19
is set to another ON state, and the solenoid is activated to lock the locking devices of all other doors.

Subsequent release of the key plate of the door key cylinder returns the key lever 1 to the neutral position again, resulting in the state shown in FIG.

Effects The locking device according to the present invention has the configuration and operation described above. For example, if the locking device according to the present invention is installed on the driver's door, the locking device according to the present invention can be locked by operating the door key cylinder of the door. When the driver's door is locked or unlocked, all other doors can also be locked or unlocked.

Also, when operating the locking knob on the driver's door,
Only the driver's door is unlocked or locked, and other doors are not affected by the unlocking or locking of the driver's door.

In addition, the locking and unlocking operations of the locking devices of other doors can be controlled by turning the key lever ON-OFF-ON of a single switch for activating the solenoid, and the locking and unlocking operation of only the driver's door is neutral. The first and second floating portions are formed between the first and second pressing portions of the key lever occupying the position and the pressure receiving portion of the locking lever located between the two pressing portions at a position close to the fixed axis. Since this can be done by simply setting the length of the gap, the width of the locking device can be kept short and the locking device installation space can also be kept small.
