[0026] The side wall 5 is provided above the left side rail 24 .

[0027] The rear wall 6 is provided above the back rail 25.

[0028] The door 7 is provided above the right side rail 24 so as to be able to open and close. This door 7 is a double door with two bifold doors on each side (near the front of the container 1 and near the rear of the container 1) of the door 7. When half of the left door (near the rear of the container 1) is opened, one-quarter of the door 7 is opened. When the left door (near the rear of the container 1) is opened entirely, one-half of the door 7 is opened. When half of the right door (near the front of the container 1) is opened, one-quarter of the door is opened. When the right door (near the front of the container 1) is opened entirely, one-half of the door 7 is opened. By opening the left door (near the rear of the container 1) entirely and the right door (near the front of the container 1) entirely, the entire right side of the container 1 can be opened.

[0029] The pair of left and right drainage grooves 8 are fitted into notches (not shown) of multiple cross members 21 along the front-to-rear direction and are bridged over the multiple cross members 21, so that they are provided on both the left and right sides of the floor surface 30 along the front-to-rear direction. Lashing bars 9 are provided inside the pair of left and right drainage grooves 8 so as to run along the drainage grooves 8. Drainage holes 80 are provided at the front and rear of the bottom of the pair of left and right drainage grooves 8. The drainage holes 80 drain water such as rainwater from the drainage grooves 8 below the floor.

[0030] A pair of left and right lashing bars 9 are provided in the drainage groove 8 so as to follow the drainage groove 8. The pair of left and right lashing bars 9 are fixed to the bottom of the drainage groove 8 by supports 90 provided at intervals along the drainage groove 8. The pair of left and right lashing bars 9 are configured in a rod shape so that carabiner hooks 131 (see FIG. 7) provided on lashing belts 130 (see FIG. 7) can be hooked onto them. The pair of left and right lashing bars 9 also have a jagged surface.

[0031] The plurality of lifting hooks 10 are welded to the outside of the pair of left and right main rails 20 at intervals in the front-to-rear direction. These plurality of lifting hooks 10 are provided under the floor, but are exposed from openings 31 in the metal plate 3 that constitutes the floor surface 30.

[0032] The connecting hook 11 is welded to the front of the front rail 23. This connecting hook 11 is connected to the detachable body vehicle 100 when the container 1 is attached to or detached from the detachable body vehicle 100.

[0033] A pair of left and right ground rollers 12 are provided at the rear lower part of the underfloor structure 2. These pair of left and right ground rollers 12 roll when the container 1 is attached to or detached from the detachable body vehicle 100. Furthermore, when the container 1 is lowered from the detachable body vehicle 100, the pair of left and right ground rollers 12 come into contact with the ground together with the pair of left and right legs 13 to support the container 1.

[0034] A pair of left and right legs 13 are provided at the front lower part of the underfloor structure 2. When the container 1 is unloaded from the detachable body vehicle 100, these left and right legs 13 come into contact with the ground together with the left and right pair of ground rollers 12 to support the container 1.

[0035] The multiple locking members 14 are welded to the inside of the rear of the pair of left and right main rails 20 at intervals in the front-to-rear direction. When the container 1 is loaded onto the detachable body vehicle 100, these multiple locking members 14 engage with a locking mechanism (not shown) of the detachable body vehicle 100, thereby preventing the container 1 from falling off.

[0036] Next, a method for securing the cargo 110 loaded in the container 1 will be described with reference to Fig. 7. Fig. 7 is a perspective view showing a state in which the cargo 110 loaded in the container 1 is secured with lashing belts 130.

[0037] When loading cargo 110 into the container 1, a pair of square beams 120 are placed on the floor surface 30 with a gap between them along the left-right direction, and then the cargo 110 is loaded from the side so that it is stretched across the pair of square beams 120. After that, a lashing belt 130 is placed on top of the cargo 110 along the left-right direction, and a pair of carabiner hooks 131 provided on the lashing belt 130 are hooked onto each of the pair of left and right lashing bars 9. The lashing belt 130 is then tightened to secure the cargo 110.

[0038] Next, a method for lifting an empty container 1 with a crane 140 will be described with reference to Figures 8 and 9. Figure 8 is a perspective view showing a state in which an empty container 1 has been lifted with a crane 140. Figure 9 is a perspective view showing the periphery of a lifting hook 10 provided under the floor of the container 1.

[0039] When lifting an empty container 1 with a crane 140, a sling wire sling 150 is used. First, the ring 151 of the sling wire sling 150 is hooked onto the carabiner hook 141 of the crane 140, and the multiple carabiner hooks 152 of the sling wire sling 150 are hooked onto each of the multiple lifting hooks 10. Thereafter, the wire 142 of the crane 140 is wound up, etc., to lift the empty container 1.

[0040] As described above, the container 1 has a front wall 4, side walls 5, and rear wall 6 on all four sides, a door 7, and an opening at the top, and is detachably mounted on a detachable body vehicle 100. The container 1 is equipped with drainage grooves 8 provided along the front-to-rear direction on each of the left and right sides of the floor surface 30, and rod-shaped lashing bars 9 provided in the drainage grooves 8 along the drainage grooves 8, to which carabiner hooks 131 provided on the lashing belts 130 are hooked.

[0041] According to such a container 1, the lashing bar 9 is provided inside the drainage groove 8, so that the lashing bar 9 does not hinder the loading and unloading of the cargo 110.

[0042] In addition, in the container 1, the lashing bar 9 has a jagged surface.

[0043] According to such a container 1, the surface of the lashing bar 9 has a jagged shape, so that when cargo is secured with the lashing belt 130, movement of the carabiner hook in the forward and backward directions can be prevented.

[0044] The container 1 is detachably mounted on a detachable body vehicle 100 and has a door 7 on its side for loading and unloading cargo from the side. The container 1 is provided with an underfloor structure 2 including a pair of left and right main rails 20 spaced apart along the front-to-rear direction, a plurality of cross members 21 suspended over the pair of left and right main rails 20 spaced apart along the front-to-rear direction, and a plurality of sub-rails 22 suspended over the plurality of cross members 21 spaced apart along the front-to-rear direction. The container 1 is also provided with a metal plate 3 provided on the underfloor structure 2 and constituting a floor surface 30.

[0045] According to this container 1, in which cargo 110 is loaded and unloaded from the side, the underfloor structure 2 includes a plurality of sub-rails 22 that are suspended over a plurality of cross members 21 at intervals along the fore-and-aft direction, so that even when a pair of square beams 120 are placed on the floor surface 30 at intervals along the left-right direction and then cargo is loaded from the side so as to be suspended over the pair of square beams 120 (see FIG. 7 ), it is possible to prevent the metal plates 3 that form the floor surface 30 from bending. By employing this underfloor structure 2, the strength of the container 1 can be increased.

[0046] In addition, in the container 1, the multiple cross members 21 have notches 210 at the portions where the multiple sub-rails 22 are spanned, and the multiple sub-rails 22 are fitted into the notches 210 of the multiple cross members 21, so that the upper surfaces of the multiple sub-rails 22 are at the same height as the upper surfaces of the multiple cross members and form a lattice together with the multiple cross members.

[0047] According to such a container 1, the upper surfaces of the multiple sub-rails 22 are flush with the upper surfaces of the multiple cross members 21, and the multiple sub-rails 22 form a lattice with the multiple cross members 21, so that even when a pair of square beams 120 are placed on the floor surface 30 at a distance from each other along the left-right direction and then cargo is loaded from the side so as to be spanned across the pair of square beams (see FIG. 7), it is possible to further prevent the metal plates 3 forming the floor surface 30 from bending. By employing such an underfloor structure 2, the strength of the container 1 can be further increased.

[0048] The container 1 has a front wall 4, side walls 5, and rear wall 6 on all four sides, and a door 7, and is open at the top, and is detachably mounted on a detachable body vehicle 100. The container 1 comprises an underfloor structure 2, a plurality of lifting hooks 10 welded to the underfloor structure 2, and a metal plate 3 provided on the underfloor structure 2 to form a floor surface 30, with a plurality of openings corresponding to the plurality of lifting hooks 10.

[0049] According to such a container 1, since the multiple lifting hooks 10 are welded to the underfloor structure 2, the strength of the four walls 4, 5, 6 and the frame of the door 7 is not required, compared to when the multiple lifting hooks 10 are provided above the four walls 4, 5, 6 or the frame of the door 7. This allows the container 1 to be made lighter.

[0050] In addition, in the container 1, the underfloor structure 2 includes a pair of left and right main rails 20 spaced apart from each other along the fore-and-aft direction, and a plurality of cross members 21 suspended over the pair of left and right main rails 20 spaced apart from each other along the left-right direction, and a plurality of lifting hooks 10 are welded to the main rails 20.

[0051] According to such a container 1, since the multiple lifting hooks 10 are welded to the main rail 20, the strength of the four walls 4, 5, 6 and the frame of the door 7 is not required, compared to when the multiple lifting hooks 10 are provided above the four walls 4, 5, 6 or the frame of the door 7. Therefore, the weight of the container 1 can be reduced.

[0052] The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the spirit and technical concept of the present invention. In other words, the position, size, length, number, shape, material, etc. of each component can be changed as appropriate.

[0053] For example, in the above embodiment, the container 1 has a door 7 on the right side, and cargo 110 is loaded and unloaded from the right side. However, the present invention is not limited to this, and any container may be used as long as it has a door on the side, and cargo is loaded and unloaded from the side. In other words, the container may have a door on the left side, and cargo is loaded and unloaded from the left side. [Explanation of symbols]
