8 is a partial perspective view of the upper surface (front portion) of the bottom plate shown in FIG.
In the rail portion 30, a plurality of vertical rollers 32a and horizontal rollers 34a are arranged in a line. A plurality of vertical rollers 32a are attached to frames 32c and 32c (L-shaped as a single unit) arranged so as to have a substantially U-shaped longitudinal section. The rotary shaft 32b of the vertical roller 32a penetrates the frame bodies 32c and 32c horizontally in a bridge state (disposed horizontally with respect to the bottom plate upper surface 15). The vertical roller 32a can rotate vertically around the rotation shaft 32b. And the frame bodies 32c and 32c which have the some vertical roller 32a are arranged in a line in the length direction of the baseplate 16 as a part of rail part 30 (refer FIG. 3).
On the other hand, the horizontal roller 34a is arranged alternately with the above-described frames 32c and 32c (a plurality of vertical rollers 32a) to constitute the rail portion 30. The rotation shaft 34 b of the horizontal roller 34 a is erected vertically with respect to the bottom plate upper surface 15. The horizontal roller 34a can rotate horizontally around the rotation shaft 34b.

On the other hand, the lower end portion (base 26) of the container main body 3 has a concave portion 27 into which the above-described rail portion 30 can be fitted. The concave portion 27 is formed over substantially the entire length of the base 26 corresponding to the rail portion 30 described above. The rail portion 30 is fitted into the concave portion 27 of the container main body 3, and the container main body 3 is mounted on the bottom plate 16 and connected. At this time, the vertical roller 32 a of the rail portion 30 contacts the inner upper surface 27 b of the recess 27. The vertical rotation of the vertical roller 32 a while contacting the inner upper surface 27 b allows the container body 3 to move relative to the bottom plate 16 along the rail portion 30.
Further, the lateral roller 34 a of the rail portion 30 contacts the inner side surfaces 27 a and 27 a of the recess 27. When the horizontal roller 34a rotates laterally while being in contact with the inner side surface 27a, the horizontal roller 34a restricts the movement (backlash) in the horizontal direction (left-right direction) of the container body 3 with respect to the bottom plate 16. Therefore, the play of the container body 3 in the lateral direction with respect to the bottom plate 16 at the time of lifting or moving can be suppressed.

An engaging device 36 for engaging and connecting with the container main body 3 is disposed on the bottom plate upper surface 15 at a position adjacent to the left and right rail portions 30. The engagement devices 36 are arranged inside the container main body 3 with respect to the rail portion 30 described above, and a plurality of the engagement devices 36 are arranged at a predetermined interval (see FIG. 3).
The engagement device 36 includes a support body 44 having an L-shaped longitudinal section, and a pair of rotating shafts 39 and 39 are fixed to the support body 44. The pair of rotating shafts 39, 39 are arranged so as to protrude in a direction perpendicular to the above-described rail portion 30 in the horizontal direction. A rolling roller 38 (an example of a rolling member) is attached to the tip of the rotating shaft 39 so as to be rotatable around the rotating shaft 39.
A hexagonal nut 40 (nut hole 42) for positioning the container body 3 with respect to the bottom plate 16 is fixed between the pair of rotating shafts 39 and 39 so as to face the rail portion 30 as described later.

The base 26 has a flat plate-like projecting portion 25 that projects from the inside of the container body 3 (see FIG. 8 (II)). The overhang portion 25 projects between the above-described rolling roller 38 and the bottom plate upper surface 15. The above-mentioned rolling roller 38 is in contact with the overhanging portion 25 while being rotatable on the upper surface of the overhanging portion 25.
Since the above-mentioned overhang | projection part 25 and the rolling roller 38 are arrange | positioned in the contact | abutting state, the container main body 3 and the baseplate 16 can be lifted in the stable connection state at the time of the lifting of the roof board 12. FIG. Further, when the container body 3 moves along the rail portion 30, the rolling roller 38 in contact with the overhanging portion 25 rolls on the upper surface of the overhanging portion 25 with the movement. For this reason, the movement of the container main body 3 along the rail part 30 is made smoothly.

9 is a partial cross-sectional view of the lower side portion of the front part of the shipping container shown in FIG.
A positioning bar 18b is attached to the base 26 through a through hole 47 at a position corresponding to the arrangement position of the engagement device 36 described above. The positioning bar 18b can be inserted into the nut hole 42 of the hexagon nut 40 at the tip 18e. The positioning bar 18b is formed with two flanges 18c and 18d having a diameter larger than that of the through hole 47 fitted around the shaft. The outer flange 18c is disposed outside the base 26. The internal flange 18d is for preventing the positioning bar 18b from coming off, and is disposed in the space 26a inside the base 26.
By pushing the positioning bar 18 b into the container body 3, the tip end portion 18 e of the positioning bar 18 b is inserted into the hexagon nut 40 (nut hole 42) of the engagement device 36 described above. Thereby, the container main body 3 and the baseplate 16 are fixed so that relative movement is impossible. The handle 18 a is held, the positioning bar 18 b is pulled out from the through hole 47, and the tip end 18 e of the positioning bar 18 b is pulled out from the nut hole 42 of the engaging device 36. Accordingly, the positioning and fixing of the container main body 3 with respect to the bottom plate 16 is released, and the container main body 3 and the bottom plate 16 can be moved relative to each other.

FIG. 10 is a side view of the shipping container.
A method for folding the shipping container 2 will be described. A position (neutral position) in which the container body 3 matches the position of the bottom plate 16 in the length direction of both is used as a reference.
The container body 3 is moved with respect to the bottom plate 16 so that the container body 3 is located behind the neutral position and the front portion of the bottom plate upper surface 15 is exposed. In this state, the front door 14a is rotated and folded toward the inside of the container body 3. Next, the container main body 3 is moved with respect to the bottom plate 16 so that the container main body 3 is positioned in front of the neutral position and the rear portion of the bottom plate 16 is exposed. In this state, the rear door 14b is turned and folded toward the inside of the container body 3.

FIG. 11 is a perspective view of the shipping container in a displaced state during lifting. FIG. 12 is a partial longitudinal sectional view of the shipping container of FIG.
Next, the lid 4 of the cylinder body 6 of the roof plate 12 is opened, and the fork 52 of the forklift 50 is inserted into the opening 5 of the cylinder body 6 to engage them. At this time, the reinforcing plates 13 at the upper four corners inside the shipping container 2 are folded into the shipping container 2 to release the basic state of the shipping container 2. When the container body 3 and the bottom plate 16 are lifted in a connected state via the engagement device 36, the rotation shafts 22a of the central hinges 22 are located at the inner positions of the transport container 2 (the rotation shafts 21a of the upper hinge 21). It is displaced to a position (substantially on a straight line connecting the rotation axis 29a of the lower hinge 29). For this reason, the pair of left and right side wall plates 28 and 28 are in a displacement state in which the central hinges 22 and 22 are folded inward substantially in synchronization with each other. Then, the roof plate 12 is lowered to the placement surface 60, and the side wall plates 28, 28 are folded inside the container main body 3.
The shipping container 2 in the folded state has a height dimension of about 1/3 as compared with the box-type basic state (see FIGS. 2 and 5). By stacking the transport containers 2 in a folded state, a plurality of transport containers can be efficiently conveyed.

Further, in the above-described transport container 2 and the folding method thereof, the engaging work is completed by storing the fork 52 of the forklift 50 in the cylinder body 6. The roof plate 12 can be lifted in a state where the upper surface of the fork 52 is in contact with the inner upper surface 6a of the cylinder body 6 (without a gap). For this reason, the roof board 12 can be lifted without rattling.
Since the folding work is performed by the forklift 50, the operator does not need to contact the side wall plates 28, 28. For this reason, folding work can be performed safely. Further, the folding work itself may be a simple work of raising and lowering the shipping container 2 with respect to the placement surface 60.

The shipping container of the present invention is not limited to the appearance, configuration, processing, display example, and the like described in the present embodiment, and various modifications, additions, and deletions can be made without changing the gist of the present invention.
In the transport container 2 in the present embodiment, the example in which the cylindrical member 10 is used as the engaging portion has been described. On the other hand, when using a lifting device having a hook-like holding claw portion such as a crane, the engaging portion may be a member having a hole with which the hook-like holding hook portion can be engaged. In this case, in order to lift the roof plate 12 stably, the engaging portions may be arranged near the four corners of the roof plate 12.
Moreover, in the container 2 for transport in this Embodiment, the example which attaches the cylindrical member 10 to the roofboard 12 upper surface was demonstrated. Unlike this, the tube body 6 may be attached to the upper surface inside the roof plate 12. In this case, the forklift 50 inserts the fork 52 into the cylinder body 6 from the front-rear direction of the transport container 2.
