Further, the annular portion 81 also regulates the axial movement of the connecting shaft 7. That is, when the lock portion 71 is inserted into the annular portion 81, the lock portion 71 cannot move in the axial direction. Therefore, the handle stopper 8 can also prevent the connecting shaft 7 from unintentionally falling out of the shaft hole 10.

On the other hand, as shown in FIG. 12B, the handle stopper 8 in the first embodiment can be slid in the upward vertical direction along the leg portion 111 of the shaft hole member 11. As a result, the restriction on the lock portion 71 is released, and at the same time, the holding state of the handle portion 72 is also released. Since the connecting shaft 7 can rotate about the shaft hole 10, the handle portion 72 can be tilted toward the front side as shown in FIG. 12 (c). This makes it easier to grip the handle portion 72, and as shown in FIG. 12D, it becomes easier to apply force when the connecting shaft 7 is pulled out from the shaft hole 10 in the axial direction. When the connecting shaft 7 is pulled out from the support column side shaft hole 101, the connection between the support column 3 and the lower panel portions 41 and 51 of the front panel 4 or the rear panel 5 is released.

Here, as shown in FIG. 6, when the upper panel portions 42 and 52 are connected to the left and right side panel 6 by the connecting mechanism 9, the lower panel portions 41 and 51 are the front panel side hinge 43 and the rear surface.

Next, a second embodiment of the foldable container according to the present invention will be described with reference to the drawings. The same or equivalent configurations as those described in the first embodiment described above are designated by the same reference numerals, and the description thereof will be omitted again.

The foldable container 1 of the second embodiment is configured so that the connecting shaft 7 can be pulled out to the support column 3 side, and the handle portion 72 is particularly large on the support column 3 side having a narrow axial direction. It made it possible to form.

As shown in FIG. 14, the connecting shaft 7 in the second embodiment has a length extending to the support column 3 side in a state of being inserted into the shaft hole 10. The shaft hole 10 has a panel side shaft hole 102 opened near the lower end of the front panel 4 and the rear panel 5, and two support column side shaft holes 101 and 101 opened near the lower end of the support column 3.

The handle portion 72 in the second embodiment has one or a plurality of rod-shaped members 721 provided in a direction orthogonal to the axial direction of the connecting shaft 7. Specifically, as shown in FIG. 15, it has two rod-shaped members 721 and a rod-shaped connecting member 722 that connects the tip portions of the rod-shaped members 721 and 721. The length of the rod-shaped member 721 is not particularly limited, but is such that an adult male can grip a fist, and it is preferable that the rod-shaped member 721 has a length of, for example, about 10 cm to 25 cm. That is, since the handle portion 72 in the second embodiment has a narrow width in the axial direction of the support column 3 and cannot be formed large in the axial direction, the length of the rod-shaped member 721 orthogonal to the axial direction is formed long. By doing so, the handle portion 72 is enlarged to make it easy to grip.

As shown in FIGS. 16 and 17, the handle stopper 8 in the second embodiment is provided on the rod-shaped member 721 constituting the handle portion 72, and has a slide portion 82 that can slide along the rod-shaped member 721. The slide portion 82 has a tilt prevention portion 83 formed at the end of the slide portion 82 on the support column side.

The slide portion 82 has two insertion holes 84 and is slidably inserted into the two rod-shaped members 721.

The tilt prevention portion 83 is for preventing the handle portion 72 from tilting, and is formed in the downward vertical direction from the support column side end portion from the slide portion 82. That is, as shown in FIG. 18, the tilt preventing portion 83 is arranged between the connecting shaft 7 and the support column 3 when it is arranged on the base end side of the rod-shaped member 721, and the connecting shaft 7 and the support column are arranged. It is locked to the inner surface 31 of 3. Therefore, the handle portion 72 is locked to the connecting shaft 7 and the support column 3 and cannot be tilted, so that the handle portion 72 is held in a state along the upper vertical direction.

On the other hand, as shown in FIG. 19, the handle stopper 8 can be slid upward along the rod-shaped member 721. When the lower end of the tilt prevention portion 83 is arranged above the connecting shaft 7, the tilt prevention portion 83 is released from the locking force of the connecting shaft 7. As a result, the handle portion 72 can be tilted in the axial rotation direction as shown in FIG.

The lateral slip prevention stopper 12 is locked to the handle portion 72 held in a state along the upward vertical direction by the handle stopper 8 to stop the movement in the axial direction. As shown in FIGS. 18 and 19, the lateral slip prevention stopper 12 in the second embodiment is projected from the support column 3 toward the handle portion 72. As a result, the axial movement of the handle portion 72 is restricted, and it is possible to prevent the connecting shaft 7 from unintentionally falling out of the shaft hole 10. The height to be projected is not particularly limited, but the support column 3 is sufficient to be locked to the handle portion 72 so as not to interfere with the other foldable container 1 when it is installed side by side. It is preferable that it is formed to the extent that it does not go out.

On the other hand, as shown in FIG. 20, when the handle portion 72 is tilted in the axial rotation direction, the restraint of the axial movement of the handle portion 72 by the lateral displacement prevention stopper 12 is released. Therefore, as shown in FIG. 21, the connecting shaft 7 can slide in the axial direction. When the connecting shaft 7 is pulled out from the panel side shaft hole 102, the connection between the support column 3 and the lower panel portions 41 and 51 of the front panel 4 or the rear panel 5 is released. As a result, the front panel 4 and the rear panel 5 can be removed from the gantry 2.

According to the foldable container 1 of the second embodiment as described above, the same effect as that of the first embodiment can be obtained, and the handle portion 72 or the like can be arranged on the support column 3 side.

The foldable container according to the present invention is not limited to each of the above-described embodiments, and can be appropriately modified. For example, the gantry 2 is not limited to a rectangular shape having front and rear edges as long sides, but may be formed in a rectangular shape having left and right edges as long sides, and the length of each side portion may be formed. May be formed in the same square shape.
