The coupling and separation between the exercise guide 534 and the exercise guide (see FIG. 13 and 536) and the exercise guide mechanism are the same as those of the first latch device 520.

In the case of the exercise guide part 536, the connection part (see Fig. 6, 1500) is connected to the exercise guide part 526 of the first latch device 520, the movement direction and characteristics of the first latch device The same as the exercise guide 526 of 520.

However, the start of the movement of the exercise guide part 534 of the second latch device 530 is referred to as the rotation of the exercise guide part 524 of the first latch device 520 and the rotation of the connection unit 1500 thereby. There is a difference.

Therefore, the separation operation of the second latch device 530 and the fixing member 550 will be replaced with a description of the separation operation between the first latch device 520 and the fixing member 550 described above.

Positions of the locking portions 524 and 534 of the first and second latch devices shown in FIG. 16 are the same as positions of the locking portions 524 and 534 of FIGS. 15 (a) and 15 (b). 30 is in an open state, and the storage container 100 is in a state of being disposed at the entrance of the storage chamber 20.

At this time, the locking pins (5247, 5347) of the locking portion (524, 534) is located in the extension groove located on the left side of the locking guide groove (112, 122), the locking step (112a, 122a) formed on the front edge of the extension groove It is arranged adjacent to and restricted from moving forward.

Meanwhile, the stoppers 111 and 121 are positioned in the stopper grooves 523 and 533, and the stopper grooves 523 and 533 surround the rear and side surfaces of the stoppers 111 and 121.

In this state, when the door 30 and the storage container 100 are separated and the user pulls the door 30, only the door 30 rotates forward, and the storage container 100 is opened.

The locking pins 5247 and 5347 are located in extension grooves provided on the left side of the locking guide grooves 112 and 122. Since the extension grooves are blocked by the locking step 112a and 122a, the door is closed. Even if the 30 is opened forward, the finishing device locking pins 5247 and 5347 are caught in the locking steps 112a and 122a, and thus the forward movement is limited.

Therefore, smooth opening of the door 30 can be realized.

As described above, the process of coupling and separating between the first latch device 520 and the fixing member 550 is substantially similar to the process of separating and coupling between the second latch device 520 and the fixing member 550. Since the second latch device 530 is only linked to the operation of the first latch device 520 by the connection unit 1500, the second latch device 530 is connected to the second latch device 530 through the description of the first latch device 520. I will replace the description.

In other words. As shown in FIG. 15 (b), the user pushes the door 30 in a state where the fixing member 550 and the first latch device 530 are separated to lift the fixing member 550 as shown in FIG. 15 (a). Enter the latch device 520.

The fixing member 550 is inserted into the insertion guide groove 5211 and pushes the first extension part 5252 of the rotational limiting part 525 back.

As a result, the rotational limiting portion 525 rotates in a clockwise direction, whereby the insertion portion 5255 of the rotational restriction portion 525 extends from the region of the second insertion groove 5245 of the locking portion 524. Departure.

The fixing pin 552 of the fixing member 550 enters the locking groove 5252, and pushes the locking groove 5524 back to rotate the locking portion 524 in a clockwise direction.

When the locking portion 524 rotates clockwise, the movement guide portion 526 connected by the locking portion 524 and the second elastic member 5292 is pulled out.

As a result, the motion guide part 526 rotates counterclockwise.

Accordingly, the first insertion groove 5244 and the insertion portion 5262 of the exercise guide part 526 are close to each other.

When the fixing member 550 completely enters, the locking groove 5524 of the locking portion 524 faces the side, and the fixing pin 552 is surrounded by the locking groove 5252. This will be.

In addition, the insertion part 5252 of the exercise guide part 526 is inserted into the first insertion groove 5244 to limit the rotation of the locking part 526.

As a result, the fixing member 550 may be completely restrained by the locking portion 524 to prevent the fixing member 550 from being separated in the forward direction.

Although the preferred embodiments of the present invention have been described above, the scope of the present invention is not limited to such specific embodiments, and a person of ordinary skill in the art is appropriately within the scope described in the claims of the present invention. Changes will be possible.
