Next, the operation will be described. When the lock lever 13 is brought to the unlock position as shown in FIG. 3 by operating the key or the sill knob, the protrusion 14d of the vertically moving link rod 14 moves to the lower end of the elongated hole 16, and the contact surface 18a of the second open lever 18
And confront each other. In this state, when the outer handle is opened and the first open lever 15 is rotated counterclockwise a through the rod 17, the protrusion 14d is laterally moved by the long hole 16 of the first open lever 15, so that the contact surface 18a Press
The second open lever 18 rotates counterclockwise about the shaft 6, and
The connecting rod 24 engaged with the cylindrical portion 23 protruding from the open lever 18 is moved down along the arc hole 22 to release the ratchet 7 from the latch 5 and open the door.

When the lock lever 13 is brought to the lock position by operating a key or a sill knob as shown in FIG. 4, the protrusion 14d of the vertically moving link rod 14 moves to the upper end of the elongated hole 16, and the protrusion 14d Opposed to the idling groove 18b. In this state, even if the outer handle is opened to rotate the first open lever 15 counterclockwise, the protrusion 14d
Is only engaged with the idling groove 18b and the second open lever 1
Since the ratchet 8 does not rotate and the ratchet 7 cannot be disengaged from the latch 5, the door cannot be opened.

However, even if the lock lever 13 is in the lock position as shown in FIG. 4, if the inner handle is opened to move the rotary lever 20 upward as shown by the arrow b, the second open by the rotary lever 20 is performed. One end 1 of lever 18
9 is moved upward, the second open lever 18 rotates counterclockwise about the shaft 6, and the connecting rod 24 engaged with the cylindrical portion 23 protruding from the second open lever 18 is directly moved along the arc hole 22. And the ratchet 7 can be released from the latch 5 to open the door. At the same time, the left rotation of the second open lever 18
The protrusion 14 of the vertically moving link rod 14 is
Press d to switch lock lever 13 to unlock position
I can. This action is a one-motion mechanism. In the one motion of the present invention, unlike the known example, the lever is not interposed between the second open lever 18 and the ratchet 7, and the second open lever 18 and the ratchet 7 are directly connected, so that the one motion is light. Move.

When the door is closed with the lock lever 13 in the locked position as shown in FIG.
Is engaged with the striker 8 and rotates, so that the rotation of the latch 5 causes the ratchet 7 to be pushed outward by the convex portion 5a formed on the outer periphery of the latch 5 (the convex portion 5).
a is pushed outward twice because there are two places). Therefore, at the time of closing the door, the second open lever 18 rotates to push down the convex portion 14c of the vertically moving link rod 14 by the engagement surface 18c of the other end 21 of the second open lever 18,
The vertically moving link rod 14 is moved downward, and this movement switches the lock lever 13 to the unlock position. At the same time, the protrusion 14d of the vertically moving link rod 14 moves to the lower end in the elongated hole 16 and comes to face the contact surface 18a of the second open lever 18, which serves as a self-cancellation mechanism.
This self-cancelling mechanism also differs from the known example in that the lever is not interposed between the ratchet 7 and the second open lever 18 but is directly connected, so that it moves slightly.

As shown in FIG. 4, when the door is closed while the lock lever 13 is in the locked position and the outer handle is opened, the door can be closed without self-cancellation. FIG. 7 shows this state. When the outer handle is opened, the first open lever 15 rotates slightly counterclockwise as compared with FIG. 4 and the projection 14 d is moved to the right by the elongated hole 16. Moving to the right, the projection 14c also moves to the right, and faces the lower part of the fitting groove 18d. When the door is closed in this state, the latch 5 rotates by engaging with the striker 8, and the protrusion 5 a of the latch 5 is formed.
Therefore, even if the ratchet 7 is pushed outward and the second open lever 18 is rotated counterclockwise, the vertically movable link rod 14 cannot be pushed down by the engaging surface 18c of the second open lever 18, and the door can be closed with the lock. .
