Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door lock device used for a side door of an automobile, and more particularly to a door lock device equipped with a missed locking mechanism.

Various door lock devices of this type have been proposed in the past, but there have been problems in that the number of component parts is large and the mechanism is complicated.

The present invention has been made in view of this problem, and its purpose is to provide a door lock device with a simple structure.

Hereinafter, the present invention will be explained in detail using the drawings.

In Figs. 1 to 8, 1 is a base plate, 2 is a body made of synthetic resin, and these are integrally laminated with a booklet machine screw 3. As shown in FIG. 3, a latch 5 is pivotally supported by a pin 4, a spring 6 rotates and urges the latch 5 in the disengagement direction via a pin 5c attached to the latch 5, and a center pin 7 is used. a rotatably supported pawl 8; a spring 9 that biases the pawl 8 toward the latch 5;
A slide block 11 and the like are provided to remove the play of the striker 10 when it is in the engaged state with the latch 5. ”]
A circular hole 8a is bored in the pole 8, and the tip of the bottle 12b, which is caulked to the A-punch lift lever 12, is inserted into the long hole 2a bored in the body 2.
It is inserted slowly and can be handled easily. As a result, the ball 8 rotates in conjunction with the open lift lever 12, and the range of rotation is limited to the range where the bottle 12b comes into contact with the inner wall of the elongated hole 2a, similar to the open lift lever 12. It will be done.

The open lift lever 12 is attached to the body 2 so as to be coaxial and rotatable with the outer lever 13, and its cut-out portion (engaging portion) 12a has a middle portion pivotally attached to the arm portion 13a of the outer lever 13. 10 lever 14
The hook 148 can be engaged with and disengaged from the hook 148. The outer lever 13 is urged to rotate clockwise in FIG. 1 by a spring 15, and its overall shape is shown in FIG. 6, and an outside handle (not shown) is attached to the arm portion 13a. A cut-and-raised portion 13C of the contact portion 13b1 and a stopper 13d at the time of full stroke 1-loak are provided. Further, one end of the locking lever 6 is rotatably attached to the end of the tenth locking lever 14 opposite to the seven hooks 14a by a snap, and the other end of the locking lever 16 is rotatably attached. , is attached to the 20th pulling lever 17 by similar means. The middle part of the twentieth locking lever 17 is pivotally attached to the inside of the side part 2b of the body 2, and the other end is connected to an inner lock button (not shown). The spring 1' 7a maintains the moderation of this 20th pulling lever 17.

Reference numeral 18 denotes an inner lever whose middle portion is pivoted inside the side portion 2b of the body 2, and whose one end is connected to an inside handle (not shown). A long hole 18a extending vertically in FIG. 7 is bored at the other end, and the bottle 19 is inserted into the long hole 18a.
7 (in the radial direction of the bottle 19). The cut-out portion 13C of the outer lever 13 is located close to the circumferential surface of the bin 19, and is adapted to move in conjunction with the inner lever 18 when in contact with the bin 19. Reference numeral 20 denotes a lever pivotally attached to the outside of the side portion 2b of the body 3-2 at its center, and the arm portion 20a
A long hole 20b is bored in the hole 20b, into which the bottle 19 is inserted.

Next, the operation of the embodiment apparatus having the above configuration will be explained.

Figures 1 to 8 show the unlocked state when the door is closed, but when opening the door in this state from inside the vehicle,
Operate the inside handle to move the inner lever 18 to the second position.
The tenth pulling lever 14 pivoted to the arm portion 13a of the outer lever 13 is rotated in the counterclockwise direction in the figure, and the outer lever 13 is rotated in the counterclockwise direction in FIG. 1 via the pin 19. Push down to the bottom of Figure 1.

This pushing down action causes the hook 14a of the tenth pulling lever 14 to push the raised portion 12a of the open lift lever 12, causing the open lift lever 12 to rotate in the counterclockwise direction in FIG. Due to the rotation of the bin 12b due to the rotation of the open lift lever 12,
When the latch 5 is removed, the locking pawl 5a and the ball 8 are disengaged, and the latch 5 is rotated clockwise in FIG. moves and the door becomes open. To open the unlocked door from outside the vehicle when the door is closed, operate the outside handle, rotate the outer lever 13 counterclockwise in FIG. Just move it to the bottom of the diagram. As a result, the door can be opened with the same operation as when opening the door from inside the vehicle.

When the unlocked door is locked from inside the vehicle, the 20th locking lever 16 rotates counterclockwise in FIG.
As the locking rod 16 is pulled up, the tenth locking lever 14 rotates counterclockwise in FIG.
Leave the open lift lever 12.

In such a locked state, even if the outside handle is operated and the outer lever 13 is rotated counterclockwise, the hook 14a of the tenth locking lever 14 will no longer touch the cut-out portion 12a of the open lift lever 12. It is possible to maintain the locked state by simply swinging without making contact.

In order to obtain the closed state again after opening m, the door lock device main body may be pressed against the slides 1 to 10.

That is, the latch 5 is held against the spring 6 until the latch 5 is engaged with the ball 8 as shown in FIG.
All you have to do is make i[+. In this case, even if the tenth locking lever 14 is in the position shown in FIG. 1 when the door starts closing, and also in the locked position, the door will be in the unlocked state after closing. The reason for this is that even if it is in the locked position, in order to move to the position shown in Fig. 3, the ball 8 must be rotated further counterclockwise than the position shown in Fig. 3 once. During this swinging, the cut-out portion 12a of the open lift lever 12 comes into contact with the tenth pulling lever 14 and rotates it in the clockwise direction in FIG. (This is called a canceling action.) However, if the tenth locking lever 14 in the locked position is pushed downward in FIG. 1 by operating the outside handle and the door is closed in this state, a so-called keyless lock can be performed. That is, when the operation (closing the door) is performed as described above, the open lift lever 1
Even if the cut-out portion 12a of No. 2 rotates in the counterclockwise direction in FIG. Therefore, even if you let go of the outside handle after closing the door, the locked state is ensured.

As explained above, the present invention pivots the tenth pulling lever to the arm portion of the outer lever that rotates according to the movement of the inside handle and the outside handle, and one end of the tenth pulling lever is It is connected to the 20th pulling lever via a rod, a hook is formed at the other end of the 10th pulling lever, and an engaging part that engages and disengages with the hook is provided on the open lift lever. When the ball and the latch are disengaged, the 20th pulling lever is used to release the 10th locking lever.
This is done by releasing the hook of the pulling lever from the engaging portion of the open lift lever. Therefore,
According to the present invention, it is possible to realize a door lock device having an extremely small number of parts and a simple structure.
