Description

[Technical Field]

[0001] The present invention relates to a container that is loaded onto and unloaded from a container loading / unloading vehicle, and more particularly to a container that is tilted when being loaded onto and unloaded. [Background technology]

[0002] Conventionally, a detachable container disaster relief vehicle has been known, in which rescue equipment necessary for rescue operations in disaster-stricken areas in the event of a disaster such as an earthquake, fire, or flooding is installed inside the container, and the container is configured to be freely loaded and unloaded using an on-board loading and unloading device (see, for example, Patent Document 1). Many types of containers have been proposed for the containers disclosed in Patent Document 1, including those equipped with firefighting equipment, communications equipment, lighting and power supply equipment, and toilet facilities. The vehicle's loading and unloading device is equipped with an L-shaped loading and unloading arm with a hook at its tip, in order to load and unload various containers between the vehicle body and the ground. The loading and unloading arm is rotatable in the fore-and-aft direction of the vehicle relative to the vehicle body. The front wall of the container is equipped with a locking portion that can be engaged and disengaged with the hook of the loading and unloading arm.

[0003] When loading or unloading a container onto or from a vehicle, the loading arm is rotated with its hook locked to the locking portion of the container. The container is tilted while moving from the ground onto the vehicle body or from the vehicle body to the ground.

[0004] Incidentally, many containers with a locking portion on the front wall that can be engaged and disengaged with the hook of a loading arm have a rear opening at the rear. Also, among containers that allow cargo to be loaded and unloaded through the rear opening, there are some that have a double-door rear door at the rear opening (see, for example, Patent Document 2). With such containers with double-door rear doors, cargo is often loaded and unloaded through the rear opening when the container is lowered to the ground or mounted on a vehicle. For example, among containers with double-door rear doors, a type that is used in detachable container disaster relief vehicles such as those described in Patent Document 1 is a hose container.

[0005] Hose containers are used to store large-diameter hoses. These large-diameter hoses are used in large-capacity drainage pump devices that drain water in the event of a flooding disaster. Large-diameter hoses have a flexible main body and a metal connecting portion, and multiple hoses are used by connecting them together. A large number of large-diameter hoses are stored in hose containers and transported by vehicles. Large-diameter hoses are loaded into and unloaded from the hose container when the hose container is lowered to the ground or mounted on the vehicle. When storing the hose container, multiple large-diameter hoses are lined up in an orderly fashion. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 10-59056 [Patent Document 2] Japanese Patent Application Laid-Open No. 2002-347883 Summary of the Invention [Problem to be solved by the invention]

[0007] However, with the conventional hose containers described above, when they are loaded or unloaded by the loading and unloading arms of a container loading and unloading vehicle, they are tilted backward, causing the stored large-diameter hoses to move toward the rear opening due to gravity, resulting in a problem of cargo collapse. When this cargo collapse occurs, the entire large-diameter hose is pushed against the rear door blocking the rear opening of the hose container, placing a load on the rear door. This causes problems such as distortion of the rear door, making it difficult to open and close the rear door, and the large-diameter hose flying out when the rear door is opened. These problems are not limited to hose containers for storing large-diameter hoses, but also occur in other types of containers in which the rear door is opened to load or unload various cargo through the rear opening.

[0008] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide a container that prevents cargo from falling over when loading and unloading onto a container detachable vehicle, and that allows cargo to be easily loaded and unloaded by opening the rear door even after loading and unloading. [Means for solving the problem]

[0009] The inventions disclosed in this specification to solve the above-mentioned problems are configured as follows: That is, a first invention is a container to be loaded onto and unloaded from a container attachment / detachment vehicle, the container comprising: a container body having a rear opening for loading and unloading cargo, a rear door for opening and closing the rear opening, and a cargo shift prevention device arranged in the interior space of the container body, the container comprising: a cargo placement space provided on the floor of the container body; the cargo shift prevention device comprising a movement restriction member arranged at least between the placement space and the rear opening and for restricting movement of cargo placed in the placement space toward the rear opening; left and right ends of the movement restriction member removably attached to or near the inner surface of a side wall of the container body; the movement restriction member being configured to be attached when the container is loaded onto or unloaded from the container attachment / detachment vehicle, and to be detached when loading and unloading the cargo through the rear opening.

[0010] According to the first aspect of the present invention, a movement restricting member is disposed between the cargo placement space in the internal space of the container body and the rear opening of the container body. The movement restricting member can restrict the movement of cargo placed in the placement space toward the rear opening. As a result, even if the container is tilted when loading or unloading a container onto or from a container detachable vehicle, the cargo will not move rearward of the movement restricting member. This prevents the cargo placed in the container placement space from collapsing. Furthermore, when loading or unloading a container, no load is applied to the rear door that blocks the rear opening of the container, preventing deformation of the rear door. Furthermore, preventing deformation of the rear door allows the rear door to be easily opened and closed after the container is unloaded. Furthermore, even after loading or unloading a container, cargo is not pushed against the rear door, preventing cargo from flying out when the rear door is opened. This allows the rear door to be easily opened and cargo to be easily loaded or unloaded, even after loading or unloading a container.

[0011] The movement restricting member is configured to be attached when loading and unloading onto and from the container detachable vehicle, but can be removed when loading and unloading cargo through the rear opening. This allows the movement restricting member to be removed when moving cargo from outside the container to the loading space, or when moving cargo from the loading space to outside the container, so the movement restricting member does not get in the way during the loading and unloading of cargo. This makes it easy to load and unload cargo.

[0012] In the second invention, in the first invention, the movement-restricting member is characterized by having a belt main body formed by combining multiple flexible belt members in a lattice pattern, and first connecting fittings for detachably attaching the left and right ends of the belt main body to left and right direction fixing fittings arranged on the inner surface of the side wall portion of the container main body or in its vicinity.

[0013] According to the second aspect of the present invention, the movement restricting member has a flexible, lattice-shaped belt body, so that when the movement restricting member is in use, it can exert its effect of restricting the movement of luggage over a wide area. Furthermore, since it can be folded compactly when not in use, the movement restricting member can be easily handled when not in use. Furthermore, since the belt body is fixed in the left-right direction by the left-right fixing fittings and the first connecting fittings, the movement restricting effect of the movement restricting member can be reliably exerted. Furthermore, the use of the first connecting fittings makes it easy to attach and detach the movement restricting member.

[0014] In a third invention, in the second invention, the cargo collapse prevention device is provided with vertical fixing fittings that are attached to the ceiling surface and / or floor surface of the container body, and the movement restriction member has a second connecting fitting for detachably attaching the upper end and / or lower end of the belt body to the vertical fixing fittings.

[0015] According to the third aspect of the present invention, the belt body is fixed in the vertical direction by the vertical fixing fitting and the second connecting fitting, which ensures that the movement-restricting member exerts its movement-restricting effect. Furthermore, the use of the second connecting fitting makes it easy to attach and detach the movement-restricting member.

[0016] In the fourth invention, in the second or third invention, the cargo collapse prevention device comprises a pair of left and right pillar mounting portions provided on the floor surface, and a pair of left and right pillar members attached to the pillar mounting portions, the pillar members are provided with the left-right direction fixing fittings, and the first connecting fitting of the movement restricting member is attached so as to be freely attached and detached to the left-right direction fixing fittings.

[0017] According to the fourth aspect of the present invention, the left and right ends of the movement-restricting member are detachably attached to the left-right fixing metal fittings of the pillar members near the inner surface of the side wall of the container body. This makes it easier to configure the portion where the movement-restricting member is attached so that it has sufficient strength due to the pillar members, compared to when the movement-restricting member is directly attached to the inner surface of the panel-like side wall of the container body. This ensures that movement of even heavy cargo can be reliably restricted.

[0018] The fifth invention is characterized in that, in the fourth invention, the left-right direction fixing fitting is provided on the rear surface of the pillar member facing the rear opening, and the first connecting fitting is configured to be detachably attached to the left-right direction fixing fitting from behind the pillar member.

[0019] According to the fifth aspect of the present invention, after a container is loaded onto or unloaded from a container attachment / detachment vehicle with the movement-restricting member attached to the pillar member, the cargo may attempt to move rearward and become attached to the movement-restricting member or the pillar member. However, even in this case, the first connecting fitting can be easily removed. That is, the cargo attaches to the front side of the pillar member, not the rear side, so the left-right fixing fitting is not covered by the cargo. This makes it easy to remove the first connecting fitting of the movement-restricting member from the left-right fixing fitting in order to move the cargo from the loading space to outside the container. [Effects of the Invention]

[0020] According to the container of the present invention, the cargo does not collapse when loading or unloading onto or from the container detachable vehicle, and even after loading or unloading, the rear door can be opened to easily load or unload cargo. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0023] FIG. 1 is a side view showing a state in which a container 1 according to one embodiment of the present invention is mounted on a container detachment vehicle 100. As shown in FIG. 1, the container 1 of this embodiment is mainly used for transporting cargo C consisting of multiple large-diameter hoses by the container detachment vehicle 100. That is, the container 1 is used as a so-called hose container. The cargo C is used in a large-capacity drainage pump device that drains water in the event of a disaster such as flooding. The container 1 of this embodiment is configured to be loaded onto and unloaded from the container detachment vehicle 100. The container 1 is transported from a garage to a work site while mounted on the container detachment vehicle 100. When the container detachment vehicle 100 arrives at the work site, the container 1 is temporarily unloaded onto the ground. After work at the work site is completed, the container 1 is loaded back onto the container detachment vehicle 100 and transported from the work site to the garage. In this embodiment, the direction in which the container detachment vehicle 100 moves forward with the container 1 mounted thereon is referred to as the forward direction of the container detachment vehicle 100 and the container 1, and the opposite direction is referred to as the rearward direction. In addition, the right direction relative to the front will be the right side of the container loading / unloading vehicle 100 and the container 1, and the left direction relative to the front will be the left side of the container loading / unloading vehicle 100 and the container 1.

[0024] The container loading / unloading vehicle 100 is provided with a loading arm 102 mounted on a vehicle chassis 101 and capable of rotating in the fore-and-aft direction of the vehicle. The loading arm 102 is formed in an L-shape. The loading arm 102 has a hook 102a at its tip. The container 1 is provided with a locking portion 22 to which the hook 102a is engaged for loading and unloading between the vehicle chassis 101 and the ground. When loading the container 1 onto the container loading / unloading vehicle 100, the loading arm 102 is rotated toward the rear of the vehicle. The hook 102a then engages with the locking portion 22 of the container 1 on the ground. From this state, the loading arm 102 is further rotated toward the front of the vehicle, thereby loading the container 1 onto the vehicle chassis 101. Conversely, when the container 1 is to be lowered to the ground, the loading arm 102 is rotated toward the rear of the vehicle. The container loading / unloading vehicle 100 also has rollers 103 at its rear end. The rollers 103 are configured to guide the bottom portion (bottom frame 17 described below) of the container 1 when loading or unloading the container 1. This allows the container 1 to be loaded or unloaded smoothly.

[0025] Fig. 2 is a perspective view of the container 1 according to this embodiment, as seen obliquely from the rear. Fig. 3 is a perspective view of the container 1 according to this embodiment, as seen obliquely from the front, with the folding canopy 40 and rear door 30 in an open state. As shown in Figs. 1 to 3, the container 1 includes a container body 10 having a rear opening 15 for loading and unloading cargo C, a rear door 30 for opening and closing the rear opening 15, a folding canopy 40 for opening and closing an upper opening 16 of the container body 10, and a cargo collapse prevention device 50 disposed in the interior space of the container body 10.

[0026] The container body 10 has a bottom wall 11, a front wall 12, a pair of left and right side walls 13, 13, and a rear frame 14. A pair of left and right bottom frames 17, 17 extending in the front-rear direction and a plurality of lateral frames 23 are attached to the bottom surface of the bottom wall 11. The pair of left and right bottom frames 17, 17 are formed from the rear end to the front end of the bottom wall 11. These bottom frames 17, 17 reinforce the bottom wall 11 and function as rolling surfaces for the rollers 103 of the container loading / unloading vehicle 100 when loading / unloading the container loading / unloading vehicle 100. A plurality of lateral frames 23 extend in the left-right direction and are provided at predetermined intervals in the front-rear direction. A pair of left and right rectangular pillar-shaped legs 19, 19 are attached to the front end of the bottom wall 11. The legs 19, 19 are set to a length such that the bottom frames 17, 17 do not directly contact the ground when the container 1 is placed on the ground. A pair of left and right ground contact rollers 18, 18 are attached to the rear end of the bottom wall 11. The ground contact rollers 18, 18 contact the ground when loading or unloading the container 1, thereby enabling smooth movement of the container 1 in the fore-and-aft direction of the vehicle.

[0027] A front frame 21 is attached to the front wall 12. The front frame 21 branches downward from its upper end, and its lower end is connected to a pair of bottom frames 17, 17. A locking portion 22 is attached to the upper end of the front frame 21. The front frame 21 reinforces the front wall 12 and improves the attachment strength of the locking portion 22. A rectangular rear opening 15 is formed in the rear frame 14. Two rear doors 30 are attached to the left and right ends of the rear frame 14 and are rotatable about a vertical axis. Cargo C can be loaded and unloaded into and from the interior space of the container 1 by opening the rear doors 30. Note that cargo C can also be loaded and unloaded into and from the interior space of the container 1 by opening the folding canopy 40. However, to load and unload cargo C through the upper opening 16 by opening the folding canopy 40, a loading and unloading machine such as a crane is required in addition to the container detachment vehicle 100. Therefore, normally, the rear door 30 is opened and luggage C is loaded and unloaded through the rear opening 15.

[0028] FIG. 4 is a perspective view showing the interior of the container 1 according to this embodiment. FIG. 5 is a rear view of the container 1 according to this embodiment with the rear door 30 open to reveal the cargo shift prevention device 50 in use. As shown in FIG. 4, a loading space S for cargo C is provided on the floor surface 11a of the container body 10. The cargo shift prevention device 50 has a movement restriction member 51 that is disposed between the loading space S and the rear opening 15 and that restricts movement of the cargo C loaded in the loading space S toward the rear opening 15. The movement restriction member 51 is configured to be attached when the container is loaded onto or unloaded from the container detaching vehicle 100, and to be detached when the cargo C is loaded or removed from the rear opening 15.

[0029] The load shift prevention device 50 includes a pair of left and right pillar members 52, 52 attached to the floor surface 11a. Left and right ends of a movement restricting member 51 are detachably attached to the pair of left and right pillar members 52, 52. The pillar members 52 are formed from metal square bars such as aluminum alloy. As shown in FIG. 5, the pillar members 52 are formed symmetrically. The vertical length of each pillar member 52 is, for example, approximately 50% to 85% of the distance from the floor surface 11a of the container 1 to the folding canopy 40. A plurality of left and right fixing metal fittings 53 are attached to the rear surface 52a of each pillar member 52 at predetermined intervals above and below. In this embodiment, four left and right fixing metal fittings 53 are attached to each pillar member 52.

[0030] As shown in FIG. 4 , the load-shift prevention device 50 has multiple pairs of pillar mounting portions 54 arranged side by side in the front-to-rear direction of the floor surface 11a. Each pair of left and right pillar members 52, 52 is configured to be attachable to and detachable from any pair of the multiple pairs of pillar mounting portions 54, 54. More specifically, in this embodiment, a total of four pairs of pillar mounting portions 54, 54 are provided from the rear end to the center of the container 1. Each pillar mounting portion 54 is disposed near the side wall portion 13 of the container 1. Each pillar mounting portion 54 is a box with a rectangular cross section whose size follows the outer shape of the pillar members 52 with a rectangular cross section. Each pillar mounting portion 54 is disposed so that its upper end is aligned with the floor surface 11a and protrudes slightly downward from the bottom wall portion 11.

[0031] Of the four pairs of pillar mounting portions 54 arranged in the front-rear direction, one pair of pillar mounting portions 54, 54 is selected. The lower ends of a pair of pillar members 52, 52 are inserted into the selected pair of pillar mounting portions 54, 54. The depth of each pillar mounting portion 54 from the floor surface 11a is set to a depth that is sufficient to withstand the force applied to the pillar member 52 in the front-rear direction. In FIG. 4, the pillar members 52, 52 are attached to the rearmost pair of the four pairs of pillar mounting portions 54, 54. When the pillar member 52 is attached to the pillar mounting portion 54, the rear surface 52a of the pillar member 52 is configured to face the rear opening 15. That is, in this state, the left-right fixing metal fitting 53 faces the rear opening 15.

[0032] Furthermore, for each of the four pairs of pillar mounting portions 54, 54, a plurality of vertical fixing metal fittings 55 are attached at predetermined intervals in the left-right direction to the floor surface 11a between the right pillar mounting portion 54 and the left pillar mounting portion 54. The vertical fixing metal fittings 55 are part of the load shift prevention device 50. In this embodiment, five vertical fixing metal fittings 55 are attached between the right pillar mounting portion 54 and the left pillar mounting portion 54.

[0033] FIG. 6 is a perspective view of the load-shift prevention device 50, seen obliquely from the rear. FIG. 7 is an enlarged view of portion A in FIG. 6. FIG. 8 is a perspective view of the load-shift prevention device of FIG. 6, disassembled into individual components. As shown in FIGS. 6 to 8, the movement restricting member 51 includes a belt main body 511 formed by combining multiple flexible belt members 511a in a lattice pattern, first connecting fittings 513 for detachably attaching the left and right ends of the belt main body 511 to left-right fixing fittings 53 of the pillar members 52, and a second connecting fitting 514 for detachably attaching the lower end of the belt main body 511 to a vertical fixing fitting 55 of the floor surface 11a. As shown in FIG. 7, the left-right fixing fitting 53 includes a base portion 53a attached to the rear surface 52a of the pillar member 52 and a ring portion 53b rotatable about an axis perpendicular to the base portion 53a. The vertical fixing metal fitting 55 has a base portion 55a attached to the floor surface 11a, and a ring portion 55b that is rotatable about an axis in the left-right direction relative to the base portion 55a.

[0034] The belt members 511a of the belt main body 511 are formed from a material such as polyester or nylon. In this embodiment, the belt members 511a are arranged so that four of them extend in the left-right direction and are aligned vertically, and five of them extend vertically and are aligned horizontally. These are then combined in a lattice pattern and connected to each other by adhesive, sewing, rivets, or the like to form the belt main body 511. As shown in FIG. 7, a metal square ring 512 is attached to the end of each belt member 511a. First connecting fittings 513 are connected to the square rings 512 at both left and right ends of the belt members 511a extending in the left-right direction among the multiple belt members 511a of the belt main body 511. The first connecting fittings 513 are formed, for example, by snap hooks.

[0035] A plurality of first connecting fittings 513 are attached in the vertical direction to the left and right ends of the belt main body 511, corresponding to the number of belt members 511a in the vertical direction. In this embodiment, four first connecting fittings 513 are attached to each of the left and right ends of the belt main body 511. The four first connecting fittings 513 on the right side of the belt main body 511 are each connected to the ring portions 53b of the horizontal fixing fittings 53 located at corresponding height positions on the right pillar member 52. Similarly, the four first connecting fittings 513 on the left side of the belt main body 511 are each connected to the ring portions 53b of the horizontal fixing fittings 53 located at corresponding height positions on the left pillar member 52. All horizontal fixing fittings 53 are provided on the rear surfaces 52a of the pillar members 52, and therefore all first connecting fittings 513 of the belt main body 511 are configured to be detachably attached to the horizontal fixing fittings 53 from behind the pillar members 52.

[0036] Of the multiple belt members 511a of the belt main body 511, a second connecting fitting 514 is connected to a square ring 512 at the lower end of the belt member 511a extending in the vertical direction. The second connecting fitting 514 is configured, for example, by a snap hook. A plurality of second connecting fittings 514 are attached to the lower end of the belt main body 511 and lined up in the horizontal direction, matching the number of belt members 511a in the horizontal direction. In this embodiment, five second connecting fittings 514 are attached to the lower end of the belt main body 511. The five second connecting fittings 514 are each connected to a ring portion 55b of a vertical fixing fitting 55 located in a corresponding position on the floor surface 11a.

[0037] When the ring portion 55b of the vertical fixing fitting 55 is connected to the second connecting fitting 514 and used, it stands upright relative to the floor surface 11a. On the other hand, when not in use, the ring portion 55b of the vertical fixing fitting 55 is laid down so as to extend along the floor surface 11a. The vertical fixing fitting 55 is always attached to the floor surface 11a with fastening members or the like, but an unused vertical fixing fitting 55 can be used as a loading space S for placing luggage C on.

[0038] In this embodiment, the load shift prevention device 50 includes a flexible auxiliary movement restricting member 56 having a mesh-like structure finer than the grid-like movement restricting member 51. The auxiliary movement restricting member 56 is formed of a material such as polyester, nylon, polyethylene, or rubber. The auxiliary movement restricting member 56 in this embodiment has an overall rectangular shape. The auxiliary movement restricting member 56 includes a mesh-like main surface portion 56a and a reinforcing frame portion 56b that reinforces the periphery of the main surface portion 56a. The vertical length of the auxiliary movement restricting member 56 is set to be, for example, 90% or more of the length from the floor surface 11a to the top end of the pillar member 52 when attached to the pillar mounting portion 54. The horizontal length of the auxiliary movement restricting member 56 is set to be, for example, 90% or more of the distance between the pair of left and right pillar members 52 when attached to the pair of left and right pillar mounting portions 54.

[0039] The auxiliary movement-restricting member 56 is detachably attached to the movement-restricting member 51. The auxiliary movement-restricting member 56 is attached, for example, to the front side of the movement-restricting member 51 (the front side of the vehicle). Since the auxiliary movement-restricting member 56 is set to the above-mentioned size, when attached to the movement-restricting member 51, it extends to the full width between the pair of left and right pillar members 52, 52 and the full vertical length. Therefore, the auxiliary movement-restricting member 56 prevents a small portion of the luggage C from moving rearward from the movement-restricting member 51.

[0040] When loading or unloading cargo C through the rear opening 15 of the container 1, the cargo collapse prevention device 50 having the above-described configuration is at least partially detached, thereby allowing smooth movement of the cargo C between the loading space S and the rear opening 15. For example, when performing the loading or unloading operation, an operator removes the first connecting fitting 513 of the movement restricting member 51 from the left-right fixing fitting 53 of the pair of left and right pillar members 52, 52, and removes the second connecting fitting 514 of the movement restricting member 51 from the up-down fixing fitting 55 of the floor surface 11a. In this case, a gap is provided between the pair of left and right pillar members 52, 52 to allow the cargo C to move. Because the first connecting fitting 513 and the second connecting fitting 514 are made of snap rings, they can be easily attached to and detached from the left-right fixing fitting 53 and the up-down fixing fitting 55. As an alternative method, it is also possible to temporarily remove the pair of left and right pillar members 52, 52, the movement restricting member 51, and the auxiliary movement restricting member 56, and then move the cargo C.

[0041] FIG. 9 is a side view showing a state in which a container 1 according to this embodiment is being loaded onto or unloaded from the container detachment vehicle 100. Consider a case in which cargo C is placed in the loading space S of the container 1, and then the container 1 is loaded onto the container detachment vehicle 100. In this case, immediately before the loading operation, an operator attaches the first connecting fitting 513 of the movement restricting member 51 to the left-right fixing fitting 53 of the pair of left and right pillar members 52, 52, and attaches the second connecting fitting 514 of the movement restricting member 51 to the up-down fixing fitting 55 of the floor surface 11a. The operator also attaches the auxiliary movement restricting member 56 to the front of the movement restricting member 51. In this way, the cargo shift prevention device 50 is put into a usable state. Then, with the cargo shift prevention device 50 in this usable state, the container 1 is loaded onto the container detachment vehicle 100.

[0042] During the loading operation of the container 1, as shown in Figure 9, after the hook 102a of the loading arm 102 of the container loading / unloading vehicle 100 is engaged with the engaging portion 22 of the container 1, the loading arm 102 is rotated toward the front of the vehicle. At this time, the container 1 is tilted backward. As a result, a force due to gravity acts on the cargo C in the container 1, tending to move it backward. At this time, the movement restricting member 51 and auxiliary movement restricting member 56 of the cargo collapse prevention device 50 support the cargo C, thereby restricting the movement of the cargo C toward the rear. As a result, the cargo C does not collapse, and the cargo C does not get pushed against the rear door 30.

[0043] When the container 1 is unloaded after being transported to a destination while loaded on the container detaching vehicle 100, the movement is the reverse of the loading operation. Therefore, even during this unloading operation, the container 1 is tilted backward. At this time, the movement restricting member 51 and the auxiliary movement restricting member 56 of the cargo collapse prevention device 50 support the cargo C, thereby restricting the rearward movement of the cargo C. As a result, the cargo C does not collapse, and the cargo C does not push against the rear door 30.

[0044] FIG. 10 is a side view showing a modified installation position of the movement restricting member 51 and the pillar members 52 of the cargo shift prevention device 50 (the side wall 13 is removed in this view). When cargo C to be loaded into the container 1 requires use of almost the entire floor surface 11a of the container 1, it is preferable to arrange the movement restricting member 51, the auxiliary movement restricting member 56, and the pair of left and right pillar members 52, 52 in positions near the rear opening 15 as shown in FIG. 4. However, depending on the type and quantity of cargo C, the cargo C may be placed in the placement space S excluding the rear portion of the floor surface 11a, as shown in FIG. 10. In such a case, arranging the movement restricting member 51, the auxiliary movement restricting member 56, and the pair of left and right pillar members 52, 52 in positions near the rear opening 15 creates a large space between the cargo C and the movement restricting member 51. If loading or unloading of the container 1 is performed in this state, the movement restricting member 51 and the auxiliary movement restricting member 56 cannot immediately restrict the rearward movement of the cargo C, which may cause the cargo C to collapse.

[0045] Therefore, in this embodiment, the size of the space between the front and rear of the luggage C placed in the placement space S and the movement restricting member 51 can be adjusted. Specifically, of the multiple pairs of pillar mounting portions 54 arranged side by side in the front-rear direction of the floor surface 11a, any pair of pillar mounting portions 54, 54 is selected to attach a pair of left and right pillar members 52, 52. The movement restricting member 51 and the auxiliary movement restricting member 56 are also attached using the pillar members 52, 52. At this time, the pair of pillar mounting portions 54, 54 is selected so as to optimize the size of the space between the front and rear of the luggage C and the movement restricting member 51. In FIG. 10 , of the four pairs of pillar mounting portions 54 arranged side by side in the front-rear direction of the floor surface 11a, the second pair of pillar mounting portions 54, 54 from the front is selected. With this configuration, the movement restricting member 51 and the auxiliary movement restricting member 56 can exhibit their cargo collapse prevention effects according to the size of the placement space S required by the luggage C.

[0046] As described above, the container 1 according to this embodiment includes the container body 10 having the rear opening 15 for loading and unloading cargo C, the rear door 30 for opening and closing the rear opening 15, and the cargo shift prevention device 50 arranged in the interior space of the container body 10, and is loaded onto and unloaded from the container detachment vehicle 100. A loading space S for cargo C is provided on the floor surface 11a of the container body 10. The cargo shift prevention device 50 includes a movement restriction member 51 arranged between the loading space S and the rear opening 15 and for restricting movement of cargo C placed in the loading space S toward the rear opening 15. The left and right ends of the movement restriction member 51 are detachably attached near the inner surface of the side wall portion 13 of the container body 10. The movement restriction member 51 is configured to be attached when the container is loaded onto or unloaded from the container detachment vehicle 100, and to be detachable when loading and unloading cargo C through the rear opening 15.

[0047] According to the above configuration, the movement restricting member 51 is disposed between the placement space S for the cargo C in the internal space of the container body 10 and the rear opening 15 of the container body 10. The movement restricting member 51 can restrict movement of the cargo C placed in the placement space S toward the rear opening 15. As a result, when loading or unloading the container 1 onto or from the container detaching vehicle 100, even if the container 1 is tilted, the cargo C will not move rearward of the movement restricting member 51. This can prevent the cargo C placed in the placement space S of the container 1 from collapsing. Furthermore, when the container 1 is loaded or unloaded, no load is applied to the rear door 30 that blocks the rear opening 15 of the container 1, so deformation of the rear door 30 can be prevented. Furthermore, since deformation of the rear door 30 can be prevented, the rear door 30 can be easily opened and closed after the container 1 has been loaded or unloaded. Furthermore, even after the container 1 has been loaded or unloaded, the luggage C is not pushed against the rear door 30, so the luggage C will not fly out when the rear door 30 is opened. This makes it possible to easily open the rear door 30 and load or unload the luggage C even after the container 1 has been loaded or unloaded.

[0048] Furthermore, the movement restricting member 51 is configured to be attached when loading or unloading the container detaching vehicle 100, but can be removed when loading or unloading the luggage C through the rear opening 15. This allows the movement restricting member 51 to be removed when moving the luggage C from outside the container 1 to the loading space S, or when moving the luggage C from the loading space S to outside the container 1, so the movement restricting member 51 does not get in the way during the loading or unloading of the luggage C. This makes it easy to load or unload the luggage C.

[0049] In the above embodiment, the movement-restricting member 51 has a belt main body 511 formed by combining multiple flexible belt members 511a in a lattice pattern, and a first connecting fitting 513 for removably attaching the left and right ends of the belt main body 511 to the left-right fixing fittings 53 of the pillar members 52, 52.

[0050] According to the above configuration, the movement restricting member 51 has a flexible, lattice-shaped belt body 511, so that when the movement restricting member 51 is in use, it can exert a movement restricting effect on the luggage C over a wide area. Furthermore, because it can be folded compactly when not in use, the movement restricting member 51 can be easily handled when not in use. Furthermore, because the belt body 511 is fixed in the left-right direction by the left-right fixing fittings 53 and the first connecting fittings 513, the movement restricting effect of the movement restricting member 51 can be reliably exerted. Furthermore, the use of the first connecting fittings 513 makes it easy to attach and detach the movement restricting member 51.

[0051] In the above embodiment, the cargo collapse prevention device 50 includes a vertical fixing metal fitting 55 attached to the floor surface 11a of the container body 10. The movement restricting member 51 has a second connecting metal fitting 514 for detachably attaching the lower end of the belt body 511 to the vertical fixing metal fitting 55.

[0052] According to the above configuration, belt main body 511 is fixed in the vertical direction by vertical fixing fitting 55 and second connecting fitting 514, thereby reliably exerting the movement restricting effect of movement restricting member 51. Furthermore, use of second connecting fitting 514 makes it easy to attach and detach movement restricting member 51.

[0053] In the above embodiment, the load shift prevention device 50 includes a pair of left and right pillar mounting portions 54, 54 provided on the floor surface 11a, and a pair of left and right pillar members 52, 52 attached to the pillar mounting portions 54, 54. A left-right fixing metal fitting 53 is provided on the pillar member 52. A first connecting metal fitting 513 is detachably attached to the left-right fixing metal fitting 53.

[0054] According to the above configuration, the first connecting fitting 513 is detachably attached to the right-direction fixing fitting 53 of the pillar member 52 near the inner surface of the side wall 13 of the container body 10. As a result, compared to when the movement-restricting member 51 is attached directly to the panel-like side wall 13 of the container 1, the portion where the movement-restricting member 51 is attached can be easily configured to have sufficient strength due to the pillar members 52, 52. This ensures that movement of even heavy cargo C can be reliably restricted.

[0055] In the above embodiment, the left-right fixing fitting 53 is provided on the rear surface 52a of the pillar member 52 facing the rear opening 15. The first connecting fitting 513 is configured to be detachably attached to the left-right fixing fitting 53 from behind the pillar member 52.

[0056] According to the above configuration, after loading / unloading the container 1 onto / from the container detaching vehicle 100 with the movement restricting member 51 attached to the pillar member 52, the cargo C may attempt to move rearward and come into close contact with the movement restricting member 51 or the pillar member 52. However, even in this case, the first connecting fitting 513 can be easily removed. That is, the cargo C comes into close contact with the front side of the pillar member 52, not with the rear surface 52a of the pillar member 52, and therefore the left-right fixing fitting 53 is not covered by the cargo C. This makes it easy to remove the first connecting fitting 513 of the movement restricting member 51 from the left-right fixing fitting 53 in order to move the cargo C from the loading space S to outside the container 1.

[0057] In the above embodiment, the load shift prevention device 50 has a flexible auxiliary movement restricting member 56 in a mesh-like shape with finer mesh than the lattice-like movement restricting member 51. The auxiliary movement restricting member 56 is detachably attached to the movement restricting member 51.

[0058] According to the above configuration, it is possible to prevent an increase in the weight of the lattice-shaped movement restricting member 51 that withstands the load from the cargo C, while the auxiliary movement restricting member 56 can prevent small portions of the cargo C from moving through the gaps in the lattice of the movement restricting member 51 toward the rear opening 15 of the container body 10. This makes it possible to reliably exert the cargo movement restriction effect while reducing the overall weight of the cargo collapse prevention device 50. Note that a lattice-shaped member such as the movement restricting member 51 and a mesh-shaped member such as the auxiliary movement restricting member 56 may be integrated into one movement restricting member.

[0059] FIG. 11 is a side view showing a container 1A according to another embodiment with cargo shift prevention devices 50 attached to the front and rear of cargo C. As shown in FIG. 11, the container 1A also has multiple pairs of pillar mounting portions 54 at the front of the floor 11a of the container main body 10A. This allows pairs of left and right pillar members 52, 52 and movement restricting members 51 to be attached to both the front and rear of the floor 11a of the container 1A. The cargo C is positioned between the front movement restricting member 51 and the rear movement restricting member 51. When the container 1A is transported by a vehicle, the front movement restricting member 51 can prevent the cargo C from striking the front wall of the container 1A during sudden deceleration. The rear movement restricting member 51 can also prevent the cargo C from striking the rear door 30 of the container 1A during sudden acceleration. When the container 1A is unloaded from the vehicle, the rear movement restricting member 51 can prevent the cargo C from pressing against the rear door 30.

[0060] 12A and 12B are rear views showing movement-restricting members 51B, 51C, and 51D attached directly to the wall surfaces of container bodies 10B and 10C in containers 1B and 1C according to other embodiments, respectively. (a) is a rear view showing one movement-restricting member 51B attached, and (b) is a rear view showing two movement-restricting members 51C and 51D attached. The containers 1B and 1C in FIG. 12 do not include the folding canopy 40 and pillar members 52 as in the containers 1 and 1A described above. In FIG. 12A, the movement-restricting member 51B is sized to extend from the floor to the ceiling of the container body 10B. The movement-restricting members 51B are attached to the wall surfaces of the container body 10B at six locations: two on the left end, two on the right end, one on the upper end, and one on the lower end.

[0061] Specifically, the movement restricting member 51B is provided with first connecting fittings 513B at two locations on each of the left and right ends. Two left-right fixing fittings 53B are provided on the inner surfaces of the left and right wall portions of the container body 10B. The first connecting fittings 513B of the movement restricting member 51B are detachably attached to the left-right fixing fittings 53B of the container body 10B. The movement restricting member 51B is also provided with second connecting fittings 514B at one location each on the upper and lower ends. One vertical fixing fitting 55B is provided on each of the ceiling and floor surfaces of the container body 10B. The second connecting fitting 514B of the movement restricting member 51B is detachably attached to the vertical fixing fitting 55B of the container body 10B. Note that the vertical fixing fittings 55B may be provided only on the ceiling surface of the container body 10B, and the second connecting fitting 514B at the upper end of the movement restricting member 51B may be attached to the vertical fixing fitting 55B on the ceiling surface.

[0062] In FIG. 12(b), two movement restricting members, a left-side movement restricting member 51C and a right-side movement restricting member 51D, are attached to the container body 10C. The left-side movement restricting member 51C and the right-side movement restricting member 51D are formed to be the same size. Two left-side fixing fittings 53C are provided on the inner surface of the left wall of the container body 10C. Two left-side fixing fittings 53D are provided on the inner surface of the right wall of the container body 10C. Two first connecting fittings 513C are provided on the left end of the left-side movement restricting member 51C. The first connecting fittings 513C of the left-side movement restricting member 51C are detachably attached to the left-side fixing fittings 53C of the container body 10C. Two first connecting fittings 513D are provided on the right end of the right-side movement restricting member 51D. The first connecting fittings 513D of the right-side movement restricting member 51D are detachably attached to the left-side fixing fittings 53D of the container body 10C. The right end of the left movement restricting member 51C and the left end of the right movement restricting member 51D are detachably connected by connecting fittings 57 at two locations.
