FIG. 3 is an exploded view of the synthetic resin body 1 as viewed from the front side. A high (thick) outer peripheral edge 31 is formed on the outer peripheral portion on the front side of the synthetic resin body 1,
The inside of the outer peripheral edge 31 is a concave portion 32. A striker 33 fixed to the vehicle body side is provided on the latch shaft 11 in the concave portion 32.
(See other drawings). A latch 34 that rotates forward by engaging with the latch 34 is axially fixed, and a lever link 35 is provided on the back side of the latch 34 so as to partially overlap with the latch 34.

At the upper end of the lever link 35, a projection 36 protruding in the rear direction is integrally formed.
Is projected to the back side of the body 1 through the outer door opening 2 and the outer door lever 1 provided on the back side of the body 1.
4 and fixed by pins 37 (FIG. 2). That is, when the back outer door opening lever 14 rotates in the direction a in FIG. 2, the protrusion 36 moves down the outer door opening 2 and the front side lever link 35 is lowered. A cancel pin 38 projecting in the front direction is provided at an upper and lower middle position of the lever link 35, and a part of the lever link 35 is formed by bending a part of the lever link 35 at a right angle in the front direction at a position slightly below the cancel pin 38. A contact portion 39 is formed, and a vertically long slit 40 is formed on the side of the contact portion 39.
To form

An engagement pin 42 provided at one end of a left and right sliding piece 41 made of a synthetic resin is engaged with the slit 40. The left and right sliding piece 41 is formed with a long hole 43 in the left and right direction, and the long hole 43 is fitted to the ratchet shaft 13. A second engaging pin 44 is provided at the other end of the left and right sliding piece 41.
A third engaging pin 45 is provided near the engaging pin 42 on the back side of the left and right sliding piece 41.
5 protrudes to the front side through the lock lever through hole 3 and engages with the forked portion 29. Therefore, when the lock lever 28 is rotated in the direction b, the fork 29 and the third engagement pin 45 are rotated.
The left and right sliding pieces 41 are moved in the direction c in FIG.

The right and left sliding pieces 4 are provided on the ratchet shaft 13.
Switching lever 4 that is superimposed on 1 and rotates by sill knob operation
6 are engaged with the long holes 47. The switching lever 46 moves in the d direction and the e direction by the sill knob operation. When the switching lever 46 moves in the direction d, the second engaging pin 44 is pressed in the direction c by the outer surface of the switching lever 46 to slide the left and right sliding pieces 41 in the c direction. Three engagement pin 45
, The lock lever 28 is rotated in the direction b.

In FIG. 3, a through hole 48 at the base of the inner door opening lever 19 is inserted through the ratchet shaft 13. A part of the lower edge of the inner door opening lever 19 is cut and raised in the front direction to form a projection 49. The pivoting end 20 of the inner door opening lever 19 is connected to the inner opening through hole 4.
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 an inner door opening lever 19 in FIG.
0 and the 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,
The base has a shaft hole 52 that engages with the ratchet shaft 13, and a rotating end farther from the shaft hole 52 collides with the cancel pin 38 when rotated, thereby unlocking the lever link 35 from the locked position. When the lever link 35 is moved downward, the contact projection 39 that contacts the contact portion 39 of the lever link 35 to rotate the ratchet 51 is formed.

When the cancel lever 50 rotates about the ratchet shaft 13, the cancel projection 53 is
Collision with the cancel pin 38 causes 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 shown in FIG. As shown in FIG.
8 just pushes sideways, then change the direction
9 acts to lower the cancel pin 38.

Thus, the pawl 55 of the ratchet 51, which is integral with the cancel lever 50, engages with the full lock engaging step 56 of the latch 34 to prevent the latch 34 from rotating in the reverse direction. Further, a part of the ratchet 51 becomes a detachable piece 57 and protrudes in a direction opposite to the claw 55, and when the ratchet 51 is mounted on the ratchet shaft 13, the detachable piece 57 faces the projection 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 release piece 57 is pushed up by the projection 49 to lower the claw 55, and the engagement between the ratchet 51 and the latch 34 is released.

[0021]

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 lock device on the door side, and the latch 34 rotates forward (clockwise).
The pawl 55 is engaged with the full lock engagement step 56 of the latch 34 to prevent the latch 34 from reversing, thereby completing the door closing. FIG.
Is in the locked state, so that the outer handle is opened, the outer door lever 14 is turned to the left, and the lever link 35 having the upper end fixed to the outer door lever 14 is moved down in the direction f. Abutting portion 39 of the lever link 35
Does not contact the contact piece 54 on the ratchet 51 side,
Since the door 9 cannot be opened because it is simply swinging downward in the direction of arrow f, the door cannot be opened. However, when the inner opening handle is opened to pull the inner cable 21 and the inner opening lever 19 is rotated upward, The door can be opened in one motion.

That is, when the inner cable 21 is pulled by operating the inner opening handle, the inner opening lever 19 moves upward about the ratchet shaft 13 and is formed at a part of the inner opening lever 19. The release piece 57 of the ratchet 51 is pushed upward by the projection 49 (as shown in FIG. 5 to FIG. 6). Therefore, the ratchet 51 turns left around the ratchet shaft 13, and the cancel lever 50 integrally fixed to the ratchet 51 by means such as tacks or spot welding also turns left, forming a part of the cancel lever 50. The cancel projection 53 is also rotated about the ratchet shaft 13. Then, cancel projection 5
Reference numeral 3 denotes a cancel projection 53 because the cancel pin 38 of the lever link 35 projects in the rotation locus.
Collides with the cancel pin 38, but the cancel protrusion 5
Since the shape of 3 is mountain-shaped as shown in FIG. 8, when the cancel projection 53 rotates from FIG. 5 to FIG.
Move to the side.

As described above, when the cancel pin 38 is pushed by the cancel projection 53, the lower end of the lever link 35
Since the contact portion 39 of the lever link 35 moves to the upper side of the contact piece 54 because the upper protrusion 36 moves to the outside of the vehicle around the center, the outer handle is opened and the outer door lever 14 is moved. When the lever link 35 is turned to the left and the lever link 35 is moved downward in the direction f, the contact portion 39 comes into contact with the contact piece 54 so that the door can be opened.

On the other hand, the pawl 55 is rotated by the left rotation of the ratchet 51 in FIG. 6, and the pawl 55 is disengaged from the full lock engagement step 56. Therefore, the latch 34 is reversed, and in FIG. 6, the door is opened by the elasticity of the seal rubber. That is, at the moment when the pawl 55 is disengaged from the full lock engagement step 56, the door is opened by the elasticity of the seal rubber. Therefore, it can be said that FIG. There is a solid difference even if the part 56 comes off, and depending on the lock device,
In some cases, the claw 55 does not come off the full lock engagement step 56.

Therefore, in the past, some safety was expected,
The rotation of the inner opening lever 19 by the inner opening handle is slightly extra. For this reason, the pushing-out action of the cancel pin 38 by the cancel projection 53 is made extra by that much, and in some cases, it may be damaged. However, in the present invention, this is shown in FIGS.
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 cover the cancel pin 38. For this reason, looking at the relationship between the cancel projection 53 and the cancel pin 38, as shown in FIG.
8 to lower by α.

That is, from the full lock engagement step 56 to the pawl 55
Until is released, the cancel pin 38 is pushed laterally by the cancel projection 53, but after the claw 55 is separated from the full lock engagement step 56, the cancel pin 38 acts to descend.

However, even if the cancel pin 38 is lowered, the contact portion 39 of the lever link 35 and the ratchet 51
Since the lever link 35 is lowered by lowering the cancel pin 38 irrespective of other parts, since there is a margin between the contact piece 54 on the side and the lever link 35 does not contact the outer peripheral wall 31, Prevent damage.

[0029]

According to the known art, when the inner opening handle is opened, the ratchet is rotated to release the pawl from the latch, and at the same time, the lever is pushed by a part of the ratchet to push the lever link. The link is moved to the unlock position to release the lock in one motion, but the opening operation with the inner opening handle is not the last thing that the ratchet releases from the latch, but gives some margin. Excessive rotation. Therefore, the operation of pushing the lever link by a part of the ratchet and laterally moving the lever link to the unlock position becomes somewhat excessive and collides with the outer wall of the lock recess, so when the inner door handle is fully opened,
The lever link is pushed too far and breaks.

However, according to the present invention, the striker 33 fixed to the vehicle body side, the latch 34 provided on the door side which rotates by engaging with the striker 33, and the full lock engagement step 56 of the latch 34 The pawl 55 is engaged with the latch 34
A ratchet 51 having a contact piece 54 for preventing reverse rotation of the outer opening lever, an outer opening lever 14 which rotates when the outer opening handle is opened, and an outer opening lever 1
4 and has a contact portion 39 which moves downward when the lever 14 rotates and presses the contact piece 54 to rotate the ratchet 51 in the releasing direction. The contact portion 39 is laterally displaced between the lock position and the unlock position. Lever link 35 and an inner door opening lever 19 that rotates when the inner opening handle is opened to release the ratchet 51 from the latch 34.
When the ratchet 51 is rotated in the release direction by the inner door opening lever 19, the ratchet 5
In a 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, a cancel projection 53 is provided on the ratchet 51 side, and a cancel pin 38 is provided on the lever link 35 side. The structure of the relationship between the cancel projection 53 and the cancel pin 38 is such that when the ratchet 51 rotates in the disengagement direction, the cancel projection 53 pushes the cancel pin 38 sideways to displace the lever link 35 to the unlock position. When the ratchet 51 is further rotated in the disengaging direction, the one-motion lock device for a vehicle is formed such that the cancel pin 38 can be lowered by the cancel protrusion 53. a. Even if the inner door opening handle is fully opened and the ratchet 51 is vigorously turned in the detaching direction, the lateral pressing of the cancel pin 38 by the cancel projection 53 is halfway, and further canceling is performed by the cancel projection 53. Since it acts to lower the pin 38, it does not break. b. No cost is required because only the shape of the cancel projection 53 is changed.

In the above description, the cancel projection 53 is formed in a mountain shape, and the tip 59 is provided with the cancel pin 38.
Since the one-motion lock device for vehicles has a shape that covers the top, it operates reliably. Further, in the above, the cancel projection 53 is a one-motion lock device for a vehicle formed of an elastic body, so that the design is easy.
Further, in the above, since the cancel projection 53 is a one-motion lock device for a vehicle formed on the cancel lever 50 that rotates integrally with the ratchet 51,
Sheet metal is also easy.
