It protrudes further to the back side of the synthetic resin body 1 and is connected to the inner handle via a wire 21.

The ratchet shaft 13 has a cancel lever 5 on the inner door opening lever 19 in FIG.
0 and ratchet 51 are fitted in that order. The cancel lever 50 and the ratchet 51 are connected to each other by a desired means such as a caulking method to form an integral structure. Cancel lever 50
Is formed by processing a relatively thin iron plate,
A shaft hole 52 that engages with the ratchet shaft 13 is provided in the base portion, and a pivot end farther from the shaft hole 52 collides with the cancel pin 38 when pivoted to unlock the lever link 35 from the locked position. When the lever link 35 is moved downward, the cancel projection 53 that moves to the position and the contact portion 39 of the lever link 35 contact to form the contact piece 54 that rotates the ratchet 51.

When the cancel lever 50 rotates about the ratchet shaft 13, the cancel projection 53 is
The cancel pin 38 collides with the lever link 35.
Is moved from the locked position to the unlocked position. In addition, since the tip 59 of the cancel protrusion 53 is bent so as to wind the cancel pin 38, the relationship between the cancel protrusion 53 and the cancel pin 38 is as shown in FIG. As shown in 8, the cancel pin 3 is initially formed by the cancel pin 53.

Further, a part of the ratchet 51 becomes a disengagement piece 57 and protrudes in the direction opposite to the claw 55. When the ratchet 51 is mounted on the ratchet shaft 13, the disengagement piece 57 faces the protrusion 49 of the inner door opening lever 19. When the inner cable 21 is pulled to rotate the inner door opening lever 19 upward, the protrusion 49 pushes up the disengagement piece 57 to lower the claw 55, and the ratchet 51 and the latch 34 are disengaged.

[0021]

[Operation] Next, the operation will be described. (Operation of FIGS. 5 and 6) When the door is closed, the striker 33 on the vehicle body side engages with the engagement groove 58 of the latch 34 of the door side locking device, the latch 34 rotates normally (clockwise), and the ratchet 51.
The pawl 55 engages with the full-lock engagement stepped portion 56 of the latch 34 to prevent the latch 34 from rotating in the reverse direction, thereby completing the door closing. Figure 5
Is locked, even if the outer handle is operated to open the door, the outer door lever 14 is rotated to the left, and the lever link 35 whose upper end is locked by the outer door lever 14 is moved downward in the f direction. , The contact portion 39 of the lever link 35
Does not hit the contact piece 54 on the ratchet 51 side,
Since 9 cannot be opened by moving downward in the direction of arrow f as it is, the door cannot be opened, but when the inner door handle is operated to pull the inner cable 21 and the inner door lever 19 is rotated upward, You can open the door in one motion.

That is, when the inner door handle is opened and the inner cable 21 is pulled, the inner door lever 19 moves upward about the ratchet shaft 13 and is formed on a part of the inner door lever 19. The detachment piece 57 of the ratchet 51 is pushed upward by the protrusion 49 (as shown in FIGS. 5 to 6). Therefore, the ratchet 51 rotates counterclockwise around the ratchet shaft 13, and the cancel lever 50 integrally fixed to the ratchet 51 by means such as a tack or spot welding also rotates counterclockwise and is formed as a part of the cancel lever 50. The canceling protrusion 53 that is also rotated about the ratchet shaft 13. Then, the cancellation protrusion 5
In No. 3, since the cancel pin 38 of the lever link 35 projects within the rotation locus, the cancel protrusion 53
Collides with the cancel pin 38, but the cancel protrusion 5
Since the shape of 3 is a mountain shape as shown in FIG. 8, when the cancel projection 53 rotates in FIGS.
Move to the side.

As described above, when the cancel pin 38 is pushed by the cancel protrusion 53, the lower end side of the lever link 35 is
Since the abutment portion 39 of the lever link 35 comes to face above the abutment piece 54 because the protrusion 36 on the upper portion moves to the outside of the vehicle, the outer handle is operated to open the outer door lever 14. When the lever link 35 is rotated counterclockwise and moved downward in the f direction, the contact portion 39 contacts the contact piece 54 and the door can be opened.

On the other hand, when the ratchet 51 is rotated counterclockwise in FIG. 6, the pawl 55 is rotated and the pawl 55 is disengaged from the full-lock engagement step portion 56. Therefore, the latch 34 is reversed, and in FIG. 6, the door is opened by the elastic force of the seal rubber. That is, at the moment when the pawl 55 is disengaged from the full-lock engagement step portion 56, the door opens due to the elastic force of the sealing rubber. Even if the part 56 comes off, there are individual differences, and depending on the locking device,
In some cases, the claw 55 does not come off the full-lock engagement step 56.

Therefore, from the conventional point of view, some safety is expected,
The inner door opening handle 19 is rotated a little extra. Therefore, the canceling pin 38 is pushed out by the canceling projection 53, and the canceling pin 38 may be damaged in some cases. Therefore, in the present invention, this may be damaged.
To solve.

(Operation of FIGS. 7 and 8) According to the enlarged view of FIG. 8, the tip 59 of the cancel projection 53 is bent so as to be covered by the cancel pin 38. Therefore, looking at the relationship between the cancel protrusion 53 and the cancel pin 38, the cancel pin 38 is pushed sideways by the cancel protrusion 53 up to the middle as shown in FIG. 8, but thereafter, the cancel pin 3 is pushed.
It acts to lower 8 by α.

That is, the full-lock engagement stepped portion 56 to the claw 55.
While the cancel pin 38 is pushed laterally by the cancel protrusion 53 until is separated, after the claw 55 is separated from the full-lock engagement stepped portion 56, the cancel pin 38 is lowered.

Therefore, even if the cancel pin 38 is lowered, the contact portion 39 of the lever link 35 and the ratchet 51 are connected.
Since the lever link 35 is lowered by lowering the cancel pin 38 regardless of the other portions because there is a space between the lever link 35 and the abutting piece 54 on the side, the lever link 35 does not abut the outer peripheral wall 31, either. Prevent damage.

[0029]

In the known device, when the inner door handle is operated to open the door, the ratchet is rotated to disengage the pawl from the latch, and at the same time, the lever link is pushed by a part of the ratchet to move the lever. The link is moved to the unlocked position to release the lock with one motion, but the door opening operation with the inner door handle is not the last thing to let the ratchet disengage from the latch, and there is some margin. Are turning excessively. Therefore, the operation of pushing the lever link by a part of the ratchet to laterally fluctuate the lever link to the unlocked position is somewhat excessive, and it collides with the outer wall of the lock recess, so when the inner door handle is fully opened,
The lever link is pushed too much to the side and damaged.

However, according to the present invention, the striker 33 fixed to the vehicle body side, the latch 34 provided on the door side which engages with the striker 33 and rotates, and the full-lock engagement step portion 56 of the latch 34. The claw 55 is engaged with the latch 34
51 for preventing reverse rotation of the outer door and an abutment piece 54 for separation, an outer door opening lever 14 that rotates when the outer door opening handle is opened, and the outer door opening lever 1
4 has a contact portion 39 that is pivotally attached to the lever 4 and that moves downward when the lever 14 rotates to push the contact piece 54 and rotate the ratchet 51 in the disengagement direction, and is laterally displaced between the lock position and the unlock position. And the inner door opening lever 19 that rotates when the inner door opening handle is operated to open and disconnect the ratchet 51 from the latch 34.
When the ratchet 51 is rotated in the detaching direction by the inner door opening lever 19, the ratchet 5
In the one-motion lock in which the lever link 35 is laterally pushed by a part of 1 to move the lever link 35 to the unlock position, the cancel projection 53 is provided on the ratchet 51 side and the cancel pin 38 is provided on the lever link 35 side. The relationship between the cancel protrusion 53 and the cancel pin 38 is provided, but when the ratchet 51 rotates in the detaching direction, the cancel pin 38 is pushed laterally by the cancel protrusion 53 to displace the lever link 35 to the unlock position. , The one-motion lock device for a vehicle is formed in such a shape that the cancel pin 38 can be lowered by the cancel projection 53 when the ratchet 51 is rotated in the detaching direction more than that. Even if the inner door handle is fully opened and the ratchet 51 is swiftly rotated in the disengagement direction, the cancel projection 53 laterally presses the cancel pin 38 halfway, and if the ratchet 51 is further rotated, the cancel projection 53 cancels. Since it acts to lower the pin 38, it does not break. b. No cost is required because only the shape of the cancel protrusion 53 is changed.

Further, in the above description, the cancel projection 53 is formed in a mountain shape, and the tip portion 59 is formed in the cancel pin 38.
The one-motion lock device for the vehicle, which is shaped to cover the top, ensures reliable operation. Further, in the above description, since the cancel projection 53 is a one-motion lock device for a vehicle formed of an elastic body, it is easy to design.
Further, in the above, since the cancel projection 53 is a vehicle one-motion lock device formed on the cancel lever 50 that rotates integrally with the ratchet 51,
Sheet metal is also easy.
