Description

[Detailed Description of the Invention] The present invention relates to a door lock device for an automobile, and more particularly, to a door lock device for an automobile that does not have a keyless mechanism.

Door lock devices incorporating a keyless mechanism have become widespread and are installed in various cars.

Although keyless mechanisms have the advantage of being able to easily lock the doors from outside the vehicle without using a key, they also have the disadvantage of making it difficult to unlock the doors if the keys are forgotten inside the vehicle.

Therefore, depending on the type of vehicle, a door lock device without a keyless mechanism is desired.

This invention was developed to meet the above-mentioned needs, and the door does not lock even if the door is closed while the inside button knob on the indoor side is pressed and the open lever that is linked to the door handle is activated. A door lock for automobiles that has a simple structure with an improved lever that functionally connects the locking lever that works with the open lever and the inside bushing knob to ensure the desired operation. The purpose is to provide equipment.

A preferred embodiment of the present invention will be described.

In order to simplify the drawings and explanations and to clarify the gist of the present invention, explanations of the latch and striker of the door lock device 1 will be omitted.

For example, a known configuration disclosed in Japanese Patent Publication No. 47-13328 may be adopted.

Please refer to FIG.

An open lever 4 is pivotally attached to a proper position on a base plate 2 via a pin 3.

One end 6 of the open lever 4 is inserted into an elongated hole of a flange 5 provided on the base plate 2, and controls the rotation range of the open lever 4 about the pin 3.

The open lever 4 is biased clockwise (as viewed in FIG. 1) by a spring I whose one end is locked to the 7-lunge 5 and the other end is locked to the open lever 4.

The open lever 4 is provided with a lock release lever part 8 at a position spaced apart from the pin 3, which cooperates with the indoor/outdoor open handle.

A locking lever 9 is pivotally attached to the base plate 2 via a pin 10 at a position apart from the open lever 4.

The locking lever 9, which is approximately T-shaped, has a pin 10 in the center and a portion 11 that interlocks with the inside bushing knob on one side.
On the other hand, there is a portion 12 that is interlocked with key operations, and further there are a pair of stoppers 13 and 13' that restrict the range of rotation about the pin 10.

The stoppers 13, 13' abut against the side edges of the base plate 2 and control the amount of movement of the locking lever in the clockwise direction button and half-hour direction.

A turn-over spring 14 is stretched between the base plate 2 and the locking lever 9.

A lift lever 15 is pivotally connected to the base plate 2 via a pin 16 between the open lever 4 and the locking lever 9.

The lift lever 15 has a generally oval shape.

The intermediate lever 17, which operatively connects the open lever 4 and the locking lever 9, consists of a first lever 18 and a second lever 19.

The first lever 18 has an elongated hole 20 at one end and is connected to the locking lever 9 via a pin 21, and the other end is pivotally connected to the open lever 4 with the pin 21.

Connect one end of the second lever 19 to the open lever 4 using the pin 26.
the first and second levers 18.19
A spring 2 having a weaker biasing force than the spring 14 is inserted between the springs 14 and 14.
2.

One end 23 of the lift lever 15 can be brought into contact with the end of the second lever 19, and the other end 24 can be brought into contact with the side edge of the first lever 18.

Further, a stopper 25 is provided at a suitable position on the first lever 18 to enable contact with the second lever 19.

In the state shown in FIG. 1, operate the indoor and outdoor open handles to move the open lever 4 in the direction of arrow A,
When the open lever 4 is rotated counterclockwise around the pin 3, the second lever 19 comes into contact with the end 23 of the lift lever 15, and the lift lever 15 is rotated counterclockwise around the pin 16. , enables door opening operation.

At this time, the first lever 18 moves relative to the locking lever 9 along the elongated hole 20 and does not apply any acting force to the locking lever 9.

When the locking lever 9 is rotated clockwise about the pin 10 by operating the key or the inside bush knob, the first and second levers 18 and 19 are rotated.
Rotates counterclockwise around pin 26.

In this state, when a force is applied to rotate the open lever 17 in the direction of arrow A, the second lever 19 is released from the contact relationship with the end 23 of the lift lever 15, so that the second lever 19 is rotated. Since there is no movement and no action is given to the locking lever 9, it is an idle operation.

See Figure 2.

FIG. 2 shows a state in which the door is closed by pressing the inside bush knob and operating the outdoor open handle.

Pushing in the inside bushing knob rotates the locking lever 9 clockwise and brings one stopper 13 into contact with the side edge of the base plate 2.

The clockwise movement of the locking lever 9 also causes the intermediate lever 17 to rotate counterclockwise about the pin 26.

When the outdoor open handle is operated in such a state, the second lever 19 moves downward without coming into contact with the end 23 of the lift lever 15, as shown in FIG.

Next, when the door is closed, a latch (not shown) engages with the striker, and the pawl rotates the lift lever 15 about the pin 16 in the direction of arrow C.

This movement occurs when the end 24 of the lift lever 15 presses the side of the first lever 18, rotates the first lever 18 clockwise while receiving resistance from the spring 22, and rotates the locking lever 9. Rotate clockwise to return the locking lever to the unlocked state.

When you release the outdoor open handle, spring 2
The first lever 18 is moved to the second lever 19 by the force applied by the second lever.
Since the biasing force of this spring 22 is smaller than the biasing force of the turnover spring 14, the locking lever 9 is not displaced.
The door lock device 1 is brought into the state shown in FIG.

As is clear from the above description of the embodiment, the intermediate lever 17 that functionally connects the open lever 4 and the locking lever 9, the first lever 18 that connects both levers 4 and 9, and the open lever 4. The second lever 19 is configured to be able to come into contact with the lift lever 15, and when an acting force is applied from the lift lever 15 to the intermediate lever 17, the first
The button and the second lever 18 and 19 are allowed to move relative to each other, and the locking lever has the function of returning to the unlocked state, so the door can be closed by pushing the inside button knob and operating the outdoor open handle. However, the door cannot be locked.
