Next, the operation of the locking mechanism will be described. First, the operation of the lock portion 10 for fixing the closed state of the suitcase 50 will be described. As shown in FIG. 7 or FIG. 8, when the lever 12 is completely pulled up or completely pushed down, the lever 12 is held in the pulled up or pushed down state by the action similar to the toggle mechanism using the coil spring 18. .

When the lever 12 is pulled up, the lock portion 10 is in the unlocked state, and the lid is open, the pin 13 is moved outside the elongated hole 14 by the coil spring 18 as shown in FIG. It is drawn to the edge. Therefore, the engaged portion 21 occupies a position where it does not interfere with the locking engaging portions B1 and B2. Further, the third lock engaging portion B3 attached to the rotating member 2 is also rotated to a position where it does not interfere with the engaged portion.

Therefore, when the lever 12 is pushed down after closing the lid, the pin 13 is moved to the inner end of the elongated hole 14 by the action of the toggle mechanism, along with the slider 17. With this movement, the engaged portion 21 provided on the slider 17 is caught by the locking engaging portions B1 and B2 provided on the lid side and is engaged with each other. At the same time, the locking claw 29 provided on the outer end of the lever 12 is fitted into the locking hole 32 of the guide rail 1 against the pressing force of the spring 30, and as shown in FIG. It catches on the edge of the hole without stopping. As a result, in this state, the lever 12 cannot be pulled up, and the locking portion 10 is locked.

In this state, which is not locked yet, as shown in FIG. 4, the pair of slide members 3 and 3 are attracted to each other by the pair of protrusions 2 b and 2 b provided on the rotating member 2. Has been. From this state, when the rotating member 2 is rotated to the locking side by the key, the sliding members 3 are moved away from each other as the protrusions 2b and 2b rotate, as shown in FIG. .

Therefore, as shown in FIG. 9, the locking engaging portion 5 at the outer end of each slide member 3 is inserted into the engaging hole 25 a of the locking engaged portion 25 provided on the lever 12. Be done. This prevents the lever 12 from being pulled up even if the locking claw 29 provided on the lock portion 10 is pressed toward the lock release side. That is, the locking mechanism is in the locked state.

Then, when the key inserted into the keyhole 2a is rotated to the unlocking side, the pair of sliding members 3 and 3 are again drawn to each other, and the locking portion 5 for locking is engaged. It comes out of the stop hole 25a and returns to the unlocked state in which the lever 12 can be pulled up. Therefore, if the locking claw 29 is pushed against the pressing force of the spring 30 and the engagement with the locking hole 32 is released, the lock portion 10 is released from the locked state.

In the unlocked state in which the pair of slide members 3 and 3 are pulled together, as shown in FIGS. 7 and 8, the protrusion 44 of the locked state display portion 40 is provided on the slide member 3. It is not in contact with the protrusion 4. Therefore, the display cylinder 41 is kept in the rotating position by the spring 43 so as to display the "OPEN" mark on the display window 26.

From this state, when the pair of slide members 3 and 3 are locked away from each other, the projections 4 push the projections 44 outwardly, as shown in FIG. Therefore, the display cylinder 41 is rotated leftward against the biasing force of the spring 43, and the mark "LOCK" is displayed on the display window 26.

Further, at the time of unlocking in accordance with the locking operation, the third locking portion B3 retracted as shown in FIG. 4 rotates together with the rotating member 2 as shown in FIG. It is moved and protrudes, and as described above, is engaged with an engaged portion (not shown) provided on the lid side case 50B side.

That is, it is possible to lock / unlock the lock portions 10, 10 provided at the two left and right positions at the same time simply by inserting the key into the key hole 2a and turning the key left and right. In addition, it is possible to interlock and disengage the third locking engagement portion B3 provided at an intermediate position between the two locking portions 10 and 10.
