たばねを示す。 2 and 3 on the side front surface of the board 1.
As shown in the figure, a first lock lever 11 is connected to the inner handle rod 6 via a support shaft 10.
and a second lock lever 12 latched to the open plate 8 are coaxially supported, and a support shaft 13
A child lever 14 is pivotally supported through a support shaft 15, and a link 16 is pivotally supported at one end on the back of the other end of the second lock lever 12 via a support shaft 15. A first pin 16a that engages with the child lever 14 is protruded from the back surface, and a second pin 16b that engages with the first lock lever 11 and the second lock lever 12 is protruded from the front surface. The guide groove 14a of the child lever 14 to be engaged is formed into a long hole so that the second lock lever 12 can swing freely, and the second pin 1
6b engages with the engagement groove 1 of the first lock lever 11
1a is formed with a locking groove 11b for locking the second pin 16b at one end and a loose fitting groove 11c for loosely fitting the second pin 16b at the other end.
The locking groove 12a of the lock lever 12 is formed in an arc shape along the rotation locus of the second pin 16b so as to always lock the second pin 16b. In the figure, 17 is an opening provided in the base plate 1 to regulate the swing angle of the child lever 14, 18 is a stopper protruding from the child lever 14 to come into contact with the side wall of the opening, and 19 is a cutout of the child lever 14. It shows a spring provided to hold the switch position.

れない。 Since the present invention is constructed as described above, when the child lever 14 is not set as shown in the second figure, the first lock lever 11 and the second lock lever 12 are locked together by the engagement of the second pin 16b. Thus, the inner handle rod 6
The opening plate 8 is rotated by the swinging of the second lock lever 12 in conjunction with the swinging of the first lock lever 11 connected to the latch 3, and the latch 3 is disengaged and unlocked, but the child lever 14 is now switched to the set state. As the link 16 rotates, the link 16 rotates about the support shaft 15, and the second pin 16b moves upward along the locking groove 12a of the second lock lever 12, and this upward movement is caused by the movement of the first lock lever 11. Free fit groove 1
1c, the first lock lever 11 connected to the inner handle rod 6 swings, but the lever 11 only swings in vain and the second lock lever 12
However, the latch 3 is not unlocked.

作を円滑に行わせることができる効果を有する。 In this way, according to the present invention, link 16 is
A locking pin 16a that is pivotally supported on the second lock lever 12 and protrudes from one surface of the link 16 is engaged with a guide groove 14a provided on the child lever 14, and
A locking pin 16b protruding from the other surface of the link 16 concentrically with the locking pin 16a is attached to the second lock lever 12.
Since the locking groove 11b provided in the first lock lever 11 and the loose fitting groove 11c continuous to the other end of the locking groove 11b are selectively engaged with each other through the locking groove 12a provided in the locking lever 11, it is a child lever. 14 is not set, when the inner handle is pulled, the first lock lever 11 connected to it is pulled, and the second lock lever 12 is moved counterclockwise via the locking pin 16b of the link 16 in the engagement groove 11b. When the child lever 14 is in the set state, the locking pin 16b of the link 16 is in the loose fitting groove 11c of the first lock lever 11, and the locking pin 16b of the link 16 is in the loose fitting groove 11c of the first lock lever 11.
The pull of the lock lever 11 is disabled, and in this case, the link 1 that is pivotally supported by the second lock lever 12
6, the locking pin 16b is inserted into the second lock lever 1.
The first lock lever 11 is inserted through the second locking groove 12a.
The locking pin 16a, which is concentric with the locking pin 16b, is connected to the locking groove 14a of the child lever 14 in a switchable manner. In order to engage the link 16, the link 16 is always engaged with the first lock lever 11, the second lock lever 12, and the child lever 14, so that the link 16 can rotate in a stable state, and the rotation operation can be performed smoothly. It has the effect of
