In the transport container 1 having the above structure, the side plate 4 is installed so as to be fitted into the side surface opening 3a of the frame 3, and the lid 5 is installed so as to be fitted into the upper surface opening 3b of the frame 3. Therefore, there is no possibility that another container or the like will come into direct contact with the side plate 4 or the lid 5 during transportation, so that the side plate 4 or the lid 5 is not easily damaged. Therefore, the transport container 1 has the effect of reducing the cost required for maintenance.

As shown in FIG. 2A or FIG. 2B, the panel constituting the side plate 4 is a corrugated cardboard plate having a hollow structure made of polypropylene, polyethylene, or plastic such as polycarbonate, and has a substantially rectangular shape. , A notch 4a is provided on one side of the rectangle. As described above, since the side plate 4 has a lightweight structure, the replacement work can be easily performed.
Further, as shown in FIG. 2C, the side plate fixing receiver 6 is a metal plate and has a substantially rectangular shape, and one side of the rectangle has the same size as the notch 4a of the side plate 4. A notch 6a is provided.

The engaging claws 12 and the convex portions 13 and 13 of the side plate fixture 7, which will be described later with reference to FIG. 4, are the notch 4a of the side plate 4, the notch 6a of the side plate fixing receiver 6, and the side surface of the square pipe 2. Each of the openings formed by 2a is formed to have a size that allows it to be inserted.
Further, the side plate fixing receiver 6 has a notch 6a and an engaging claw of the side plate fixing tool 7 in the notch 6a and the notch 4a when the side plate 4 is installed in the side opening 3a of the frame 3 with respect to the square pipe 2 of the frame 3. 12 and the convex portions 13, 13 are welded to a position where they can communicate with each other.

As shown in FIGS. 3 and 4, the side plate fixture 7 is engaged with a flat plate-shaped base member 11 having a rectangular shape in a plan view and a back surface 11b in the vicinity of the end portion 11a of the base member 11. It is composed of a claw 12 and a pair of convex portions 13 and 13 arranged on both sides thereof so as to be symmetrical with respect to the engaging claw 12 as a center.
That is, the convex portions 13 and 13 also project from the back surface 11b near the end portion 11a of the base member 11.
The engaging claw 12 is provided substantially in the center in the width direction of the base member 11 (the direction perpendicular to the paper surface in FIG. 4C).

The engaging claw 12 protrudes toward the inner surface 13a of the convex portion 13 when viewed from the side so as to be engaged with the notch 6a in a state of being inserted into the notch 6a of the side plate fixing receiver 6. As described above, the engaging portion 12a is provided, and the inclined portion 12c is provided so as to be tapered from the engaging portion 12a to the tip 12b, and is provided between the base end of the engaging claw 12 and the engaging portion 12a.

Can be done.
At this time, as described above, in the base member 11, the inner wall surface of the opening 11d is formed in a tapered shape so that the opening area on the front surface 11c side is wider than the opening area on the back surface 11b side. Therefore, the movable range of the tool 14 inserted from the opening 11d in order to deform the engaging claw 12 is widened.
Therefore, the above-mentioned work of bending the engaging claw 12 at the tip of the tool 14 can be easily performed.

Here, a method of fixing the side plate 4 to the square pipe 2 of the frame 3 by using the panel fixing structure of the present invention including the side plate fixing receiver 6 and the side plate fixing tool 7 will be described with reference to FIGS. 6 and 7. do.
6 (a) is a cross-sectional view taken along the line FF in FIG. 1 (b), and FIG. 6 (b) shows a state in which the side plate 4 is installed on the square pipe 2 in FIG. 6 (a). It is a figure. 7 (a) and 7 (b) are views showing a state in which the side plate fixing tool 7 is attached to the side plate fixing receiving tool 6 in FIG. 6 (b).
Note that, in FIGS. 6 and 7, only the square pipe 2 in which the side plate fixing receiver 6 is installed is shown out of the 12 square pipes 2 constituting the frame 3. Further, the side plate 4 and the side plate fixture 7 in FIGS. 6 (b), 7 (a), and 7 (b) are shown in FIG. 1 (b) in the same manner as in the case of the square pipe 2 and the side plate fixing receiver 6. It shows the state of being cut by the cross section of the FF line shown.

As described above, when the side plate 4 is installed so as to be fitted into the side opening 3a (see FIG. 1A) of the frame 3, it is installed in the square pipe 2 as shown in FIG. 6A. The side plate 4 is parallel to the side plate fixing receiver 6, and the notch 4a and the notch 6a are in a state where the engaging claw 12 of the side plate fixing tool 7 and the convex portions 13 and 13 can communicate with each other.
Therefore, when the side plate fixture 7 is moved in the direction indicated by the arrow G in FIG. 6 (b), the engaging claw 12 is deformed so that the tip 12b bends toward the back surface 12e, and then the engaging portion 12a becomes. When it passes through the notch 6a of the side plate fixing receiver 6, the deformed state of the tip 12b is restored and the original shape is restored.
Then, as shown in FIG. 7A, the engaging portion 12a engages with the notch 6a (see FIG. 6B) of the side plate fixing receiver 6, so that the engaging claw 12 is used for fixing the side plate. It becomes impossible to separate from the receiver 6. As a result, the side plate 4 is fixed to the frame 3 (see FIG. 1A) in a state of being sandwiched from both sides by the side plate fixing receiver 6 and the side plate fixing tool 7.

On the other hand, in the state shown in FIG. 7A, as shown in FIG. 7B, the thin portion 12d at the tip of the tool 14 inserted into the opening 11d from the side of the front surface 11c of the base member 11 (FIG. 6). (B)) is pushed so that the tip 12b of the engaging claw 12 is pressed until the engaging portion 12a does not engage with the notch 6a (see FIG. 6B) of the side plate fixing receiver 6. When bent, the engaged state of the engaging portion 12a and the notch 6a (see FIG. 6B) is released, and the engaging claw 12 can be detached from the side plate fixing receiver 6.

At this time, since the convex portions 13, 13 are locked to the notch 6a (see FIG. 6B) of the side plate fixing receiver 6, the posture of the base member 11 with respect to the side plate fixing receiver 6 is maintained. .. As described above, in the side plate fixture 7, since there is no possibility that the base member 11 will move arbitrarily when the tool 14 inserted into the opening 11d of the base member 11 is operated, the engaging claw is used by using the tool 14. The work of bending the tip 12b of the 12 can be easily performed.
If the side plate fixture 7 is not provided with the convex portions 13 and 13, it is not easy to perform the work of deforming the engaging claw 12 by the tool 14, but the engaging portion 12a is destroyed by using the tool 14. Then, the engagement state of the engaging portion 12a with the notch 6a (see FIG. 6B) of the side plate fixing receiver 6 can be eliminated. However, in this case, the side plate fixture 7 cannot be used repeatedly.
On the other hand, according to the panel fixing structure according to the present invention, the side plate fixing tool 7 can be removed from the side plate fixing receiving tool 6 without breaking the engaging portion 12a, so that the side plate fixing tool 7 is repeatedly used. It is possible.

As shown in FIG. 7B, the side plate fixing tool 7 is moved in the direction indicated by the arrow H while the engaging claw 12 is deformed by the tool 14, and the notch 6a (notch 6a) of the side plate fixing receiving tool 6 is moved. When the engaging claw 12 is pulled out from the notch 4a (see FIG. 6B) of the side plate 4 (see FIG. 6B), the side plate 4 can be removed from the frame 3 (see FIG. 1A). It becomes a state.

Next, the structure for fixing the lid 5 to the frame 3 will be described with reference to FIGS. 8 to 11.

Here, a method of fixing the lid 5 to the square pipe 2 of the frame 3 by using the lid fixing receiver 8 and the lid fixing tool 9 will be described with reference to FIGS. 12 and 13.
12 (a) is a cross-sectional view taken along the line NN in FIG. 1 (b), and FIG. 12 (b) is a lid 5 so as to be fitted into the upper surface opening 3b of the frame 3 in FIG. 12 (a). It is a figure which shows the state which is installed. 13 (a) and 13 (b) are views showing a state in which the lid fixing tool 9 is attached to the lid fixing receiving device 8 in FIG. 12 (b).
Note that, in FIGS. 12 and 13, only the square pipe 2 in which the lid fixing receiver 8 is installed is shown out of the 12 square pipes 2 constituting the frame 3. Further, the lid 5 and the lid fixture 9 in FIGS. 12 (b), 13 (a) and 13 (b) are shown in FIG. 1 (b) in the same manner as in the case of the square pipe 2 and the lid fixing receiver 8. It shows the state of being cut in the cross section of the NN line shown.

As described above, when the lid 5 is installed so as to be fitted into the upper surface opening 3b (see FIG. 1 (a)) of the frame 3, it is installed in the square pipe 2 as shown in FIG. 12 (a). The lid 5 is parallel to the lid fixing receiver 8, and the through hole 5a and the through hole 8a are in a state where the engaging claw 16 of the lid fixing tool 9 and the convex portions 17 and 17 can communicate with each other.
Therefore, when the lid fixture 9 is moved in the direction indicated by the arrow P in FIG. 12B, the engaging claw 16 is deformed so that the tip 16b is bent in the direction of the back surface 16e, and then the engaging portion 16a is formed. When the lid fixing receiver 8 passes through the through hole 8a, the deformed state of the tip 16b is restored and the original shape is restored.
Then, as shown in FIG. 13A, the engaging portion 16a engages with the through hole 8a of the lid fixing receiver 8, so that the engaging claw 16 cannot be disengaged from the lid fixing receiver 8. .. As a result, the lid 5 is fixed to the frame 3 (see FIG. 1A) so as to be sandwiched from above and below by the lid fixing receiver 8 and the lid fixing tool 9, so that the lid 5 cannot be opened or closed.

On the other hand, in the state shown in FIG. 13A, as shown in FIG. 13B, the thin portion 16d at the tip of the tool 14 inserted into the opening 15d from the side of the front surface 15c of the base member 15 (FIG. 11). (See (b)) is pushed, and the tip 16b of the engaging claw 16 is bent until the engaging portion 16a does not engage with the through hole 8a of the lid fixing receiver 8. The engaged state of the through hole 8a (see FIG. 12B) is eliminated, and the engaging claw 16 can be detached from the lid fixing receiver 8.
At this time, since the convex portions 17 and 17 are engaged with the through holes 8a of the lid fixing receiver 8, the posture of the base member 15 with respect to the lid fixing receiver 8 is maintained.
As described above, in the lid fixing tool 9, since there is no possibility that the base member 15 will move arbitrarily when the tool 14 inserted into the opening 15d of the base member 15 is operated, the engaging claw is used by using the tool 14. The work of bending the tip 16b of 16 can be easily performed.

If the lid fixture 9 is not provided with the convex portions 17 and 17, it is not easy to perform the work of deforming the engaging claw 16 by the tool 14, but the engaging portion 16a is destroyed by using the tool 14. Then, the engagement state of the engaging portion 16a with the through hole 8a of the lid fixing receiver 8 can be eliminated. However, in this case, the lid fixture 9 cannot be used repeatedly.
On the other hand, according to the panel fixing structure according to the present invention, the lid fixing tool 9 can be removed from the lid fixing receiving tool 8 without breaking the engaging portion 16a, so that the lid fixing tool 9 is used repeatedly. It is possible.

As shown in FIG. 13B, the lid fixing tool 9 is moved in the direction indicated by the arrow Q while the engaging claw 16 is deformed by the tool 14, and the through hole 8a of the lid fixing receiving tool 8 ( When the engaging claw 16 is pulled out from the through hole 5a (see FIG. 12B) of the lid 5 (see FIG. 12B), the lid 5 can be opened and closed.
As described above, in the panel fixing structure of the present invention including the side plate fixing receiver 6 and the side plate fixing tool 7 or the lid fixing receiving tool 8 and the lid fixing tool 9, the side plate fixing tool 7 and the lid fixing tool can be easily operated. 9 engages with the side plate fixing receiver 6 and the lid fixing receiver 8, respectively, or the engaged state thereof is easily released.

Therefore, according to the panel fixing structure of the present invention, the work of fixing the side plate 4 and the lid 5 to the frame 3 of the transport container 1 in a state where they can be easily attached and detached can be easily and efficiently performed.
Further, by operating the tool 14 inserted into the openings 11d and 15d from the front surface side of the base members 11 and 15 to elastically deform the engaging claws 12 and 16, the side plate 4 fixed to the frame 3 can be easily formed. It can be removed and the lid 5 can be easily opened and closed.
Since such a panel fixing structure is used for the transport container 1, it is not necessary to provide a screw hole for screwing the side plate 4 and the lid 5 to the square pipe 2. Therefore, it is possible to prevent a situation in which the load is wet, the square pipe 2 is expanded and deformed, or the square pipe 2 is rusted by the water that has entered through the screw hole and the gap between the screws. Further, unlike the case where the side plate 4 and the lid 5 are screwed to the square pipe 2, the process of manually fixing the screw and then applying the silicone agent to the head of the screw does not occur, so that the side plate 4 and the lid do not occur. Even if 5 is damaged or deteriorated, the replacement work thereof can be easily performed in a short time. Therefore, in the transport container 1, it is possible to reduce the cost required for maintenance.

Here, a case where the side plate fixture 7 in the panel fixing structure of the present invention is manufactured by injection molding will be described with reference to FIGS. 14 and 15.
