[0063] After closing the right door section 60 and the left door section 70, the rotating gripping sections 64a, 74a can be grasped and rotated to cause the locking rods 61b, 71b to protrude from the through holes 61a, 71a and be inserted into locking holes in the lower part of the ceiling frame 41 (not shown), thereby locking the door sections 60, 70 and bringing them into the closed state.

[0064] As shown in Figure 13, when opening the right door section 60 and the left door section 70, the rotating gripping sections 64a, 74a are grasped and rotated to insert the locking rods 61b, 71b into the first right door section panel 61 and the first left door section 71, and then the locking rods are removed from the locking holes in the lower part of the ceiling frame 41, and the right door section 60 and the left door section 70 are pulled toward you.

[0065] In addition, when the right door section 60 and the left door section 70 are opened, the right door section 60 and the left door section 70 can be locked and fixed by the door section stoppers 44 attached to the right side and left side of the container 1.

[0066] From the closed state of the right door section 60 and the left door section 70 shown in Figure 14(a), the right door section 60 and the left door section 70 can be pulled forward and folded in two using hinges 63, 73 (not shown) to bring the right side and left side closely into contact with the panel section 30, as shown in Figure 14(b), thereby opening the right door section 60 and the left door section 70.

[0067] 14(c), by tilting the door stopper 44 from a vertically erected state to a horizontal state, the locking rods 61b, 71b protruding from the through-holes 61a, 71a in the upper parts of the first right door panel 61 and the first left door panel 71 can be inserted into the fastening holes 45a of the door stopper 44. This causes the locking rods 61b, 71b of the right door section 60 and the left door section 70 to be locked by the fastening holes 45a of the door stopper 44, and the right door section 60 and the left door section 70 can be fixed in the open state.

[0068] (Container assembly method) Next, a method for assembling the container 1 will be described.

[0069] The assembly method for container 1 is as follows: a packing step S1 in which the column portion 20, the panel portion 30, the ceiling frame portion 40, the shelf portion 50, the right door portion 60, and the left door portion 70 are stacked on top of the lower frame portion 10 and then packed; a delivery step S2 in which the container 1a in the packaged state packaged in the packaging step S1 is loaded onto a vehicle V and delivered to a delivery location; a lower frame assembly step S3 of unpacking the packaged container 1a and attaching the lower frame cover 14 and the lower panel 15 to the lower frame 11; a column attachment step S4 in which the protrusions 12 at the four corners of the lower frame 11 are inserted into the four columns 20, respectively; a panel part mounting step S5 in which the column part 20 mounted on the lower frame 11 in the column part mounting step S4 is inserted into the panel part 30 and mounted; In the panel unit mounting step S5, the convex portions 42 at the four corners of the ceiling frame 41 are inserted into the column portion 20 to which the panel unit 30 has been attached, and the ceiling frame unit 41 is then covered with the ceiling panel 43 in a ceiling frame unit mounting step S6. a shelf mounting step S7 of mounting a shelf 50 in the storage space 2 inside the container 1; a door unit mounting step S8 in which the right door unit 60 and the left door unit 70 are mounted to the panel unit 30 so as to be openable and closable; a cushion material attachment step S9 in which cushion materials 16 are attached to the lower frame portion 10 and the ceiling frame portion 40; a disassembly step S10 of disassembling the container 1 into individual components; It consists of:

[0070] (Packing step) The first step, packing step S1, will be described.

[0071] As shown in Figure 11, the components of the container 1 shown in Figures 1 and 9 are stacked on the lower frame 11, the casters 13 are exposed to allow movement, and the stacked components are wrapped in plastic film to prevent them from shifting, resulting in a packaged container 1a.

[0072] This allows the container 1 to have a small, compact configuration. Furthermore, since the container 1 can be moved by rolling the casters 13 in such a compact configuration, the packed container 1a can be easily moved.

[0073] (Delivery step) The delivery step S2, which follows the packing step S1, will now be described.

[0074] As shown in FIG. 15(b), the container 1a in the packaged state shown in FIG.

[0075] Figure 15(a) shows the state of a vehicle V when a conventional container C, i.e., a container that has been assembled and loaded at a company that manufactures the container, is delivered to the delivery location. Because the conventional container C is assembled, only a certain number of conventional containers C, for example, 10, can be loaded onto the vehicle V.

[0076] 15(b) shows the state of the vehicle V on which the packaged container 1a of the present invention is loaded and delivered to the delivery location. Since the container 1 is assembled at the delivery location, by combining known pallets that can be combined vertically within the loading platform of the vehicle V to form a space between the top and bottom, a predetermined number of packaged containers 1a, for example 30, can be loaded into the space formed.

[0077] Then, at the location where the containers 1 are delivered, the packed containers 1a are sequentially unloaded from the vehicle V and rolled on the casters 13 to be moved to the assembly location.

[0078] This allows a larger number of packed containers 1a to be loaded onto a vehicle V, and fewer vehicles V are required to load the packed containers 1a, compared to when conventional containers C are delivered in an assembled state.

[0079] (Lower frame assembly step) The lower frame assembly step S3, which follows the delivery step S2, will now be described.

[0080] First, the container 1a in a packaged state that has been moved to the delivery location in the delivery step S2 is unpacked.

[0081] Next, as shown in FIGS. 16 and 17, the lower frame cover 14 is attached to the lower frame 11 so that the protrusions 12 of the lower frame 11 are inserted into the openings 14a of the lower frame cover 14.

[0082] 18 and 19, the lower panel 15 is attached to the lower frame 11 to which the lower frame cover 14 is attached. During attachment, the cutout portions 15a of the lower panel 15 are positioned inside the protrusions 12 at the four corners of the lower frame 11, so the container 1 can be used without the lower panel 15 falling off the lower frame 11 even without fastening it with a fastening member.

[0083] (Pole mounting step) The pillar attachment step S4, which follows the lower frame assembly step S3, will now be described.

[0084] As shown in Figure 20, the convex portions 12 provided at the four corners of the lower frame 11 are inserted into the lower hollow portion 23 which is one end side of the column portion 20. As shown in Figure 21, when the convex portion 12 of the lower frame 11 is inserted into the lower hollow portion 23 of the column portion 20, the mounting hole 24 of the lower hollow portion 23 of the column portion 20 is positioned to align with the female screw hole 12a provided in the convex portion 12 of the lower frame 11. Therefore, the column portion 20 can be fixed to the convex portion 12 of the lower frame 11 by inserting a fastening member into the mounting hole 24 of the column portion 20 and fastening it to the female screw hole 12a.

[0085] Furthermore, the mounting holes 24 in the lower hollow portion 23 of the column portion 20 and the female screw holes 12a in the protrusions 12 are aligned in the oblique direction. Therefore, by inserting the protrusions 12 into the lower hollow portion 23 of the column portion 20 so that the mounting holes 24 and the female screw holes 12a of the protrusions 12 of the lower frame 11 are aligned, the column portion 20, which has a rectangular cross section, can be oriented in the intended direction.

[0086] As a result, if a welded square pipe is used as the column portion 20, a welded seam will be formed in the longitudinal direction of the column portion 20, but this seam can be positioned in the open U-shaped part of the protrusion 12. Then, the protrusion 12 can be smoothly inserted into the lower hollow portion 23 of the column portion 20. Furthermore, the lower hollow portion 23 of the column portion 20 and the protrusion 12 can be brought into surface contact, improving the fastening strength.

[0087] Furthermore, because the mounting holes 24 are formed as countersunk holes, by using countersunk screws as fastening members, the centers of the fastening members, mounting holes 24, and female threaded holes 12a can be aligned simply by fastening, making it possible to easily fix the column 20 in the desired position. Furthermore, because the heads of the countersunk screws can be sunk into the mounting holes 24, the column 20 can be smoothly inserted into the panel 30, which will be described later.

[0088] Furthermore, since the insertion portion 32 of the panel portion 30 covers and conceals the mounting hole 24 of the column portion 20, even if the fastening member loosens, it will not fall off, and unintentional disassembly of the container 1 during use can be prevented.

[0089] (Panel mounting step) Next, the panel mounting step S5, which is performed after the column mounting step S4, will be described.

[0090] As shown in Figure 22, in the pillar mounting step S4, two of the four pillars 20 are inserted into the protrusions 12 of the lower frame 11 on the right side and two on the left side, and one set of pillars 20 is inserted into the insertion opening 32a, which is the opening at the lower end of the insertion portion 32 of the panel portion 30, to mount the two panel portions 30.

[0091] (Ceiling frame mounting step) Next, the ceiling frame part mounting step S6, which is performed after the panel part mounting step S5, will be described.

[0092] As shown in Figure 23, in the pillar mounting step S4, the protrusions 42 at the four corners of the ceiling frame 41 are inserted into the upper hollow portions 21 of the four pillars 20 into which the protrusions 12 of the lower frame 11 have been inserted.

[0093] 24(a) and 24(b), at this time, the upper hollow portion 21 and mounting hole 22 of the column portion 20 inserted into the insertion portion 32 of the panel portion 30 in the panel portion mounting step S5 are configured to be exposed from the insertion opening 32a on the upper end side of the insertion portion 32 of the panel portion 30. This allows a fastening member to be inserted into the mounting hole 22 of the column portion 20 and fastened to the female thread hole 42a, thereby fixing the convex portion 42 of the ceiling frame 41 to the column portion 20.

[0094] As shown in Figure 24(c), after inserting the convex portion 42 of the ceiling frame 41 into the upper hollow portion 21 of the column portion 20, the ceiling panel 43 is placed over the ceiling frame 41. The ceiling panel 43 covers and conceals the mounting holes 22 of the upper hollow portion 21 of the column portion 20, protecting the fastening members that secure the column portion 20 and the ceiling frame 41, and preventing problems such as an object coming into contact with the head of the fastening member and loosening the fastening member or making it impossible to refasten the fastening member.

[0095] (Shelf mounting step) Next, the shelf mounting step S7, which is performed after the ceiling frame mounting step S6, will be described.

[0096] As shown in Figure 25, fastening members are inserted into the mounting holes 32b drilled in the insertion portion 32 of the container 1 and the threaded holes 20a drilled in the pillar portion 20 and tightened, and the shelf fastening frame 54 is attached to the tightened fastening members (see Figure 27).

[0097] Specifically, fastening members are inserted and tightened into the mounting holes 32b drilled in the insertion portion 32 of the panel portion 30 and the female screw holes 20a drilled in the column portion 20. Then, the heads of the tightened fastening members are inserted and locked into the potbelly holes 54a drilled at both ends of the shelf-mounting frame 54 shown in Figure 9(b) to attach the shelf-mounting frame 54.

[0098] As shown in FIG. 25, in this embodiment, shelf fastening frames 54 are attached to the right and left side surfaces of the upper, middle and lower levels in the storage space 2 inside the container 1.

[0099] As shown in Figure 26, a shelf 51 is attached to the storage space 2 inside the container 1 to which the shelf fastening frame 54 is attached. Specifically, as shown in Figure 27, the end of the beam 52 of the shelf 51 is placed on the shelf locking portion 54b of the shelf fastening frame 54. Then, fastening members are inserted into the mounting holes 52a provided at the end of the beam 52 and fastened to the female threaded holes 54c, thereby fixing the shelf 51 to the shelf locking portion 54b.

[0100] (Door mounting step) The door part mounting step S8, which is performed after the shelf part mounting step S7, will now be described.

[0101] As shown in Figure 28, second removable hinges 65, 75 attached to the right door section 60 and left door section 70 are attached to the first removable hinge 33 attached to the panel section 30 via pivot pins 34 not shown.

[0102] 29, after the right door section 60 and the left door section 70 are attached to the container 1, they are closed to cover the opening of the container 1. Then, fastening members are inserted into the mounting holes of the hinges 46 of the door stoppers 44, the mounting holes 43a of the ceiling panel 43, and the female threaded holes 41a of the ceiling frame 41, and tightened to fix the door stoppers 44 to the ceiling panel 43 and the ceiling frame 41.

[0103] (Cushioning material installation step) Next, the cushioning material attaching step S9, which is performed after the door portion attaching step S8, will be described.

[0104] As shown in Figure 30, the cushion material 16 is abutted against the four corners of the ceiling panel 43, and fastening members are inserted and tightened into the mounting holes 16a of the cushion material 16, the mounting holes 43a of the ceiling panel 43, and the threaded holes 41a of the ceiling frame 41, thereby fixing the cushion material 16 to the ceiling panel 43 and the ceiling frame 41.

[0105] Next, the cushion material 16 is placed against the four corners of the lower frame 11 and the lower frame cover 14, and fastening members are inserted into the mounting holes 16a of the cushion material 16, the mounting holes 14b of the lower frame cover 14, and the threaded holes 11a of the lower frame 11 and tightened to fix the cushion material 16 to the lower frame cover 14 and the lower frame 11.

[0106] Through the above steps, the packaged container 1a can be assembled into the container 1.

[0107] (Disassembly steps) Finally, a disassembly step S10, which is carried out when a part of the container 1 is damaged, will be described.

[0108] As shown in Figures 1, 25 and 26, the container 1 can be assembled by inserting each component or inserting fastening members and tightening and fixing them, so that the container 1 can be delivered and disassembled into individual components again at the location where it will be used without the need for special tools.

[0109] As a result, if a part of the assembled container 1 is damaged, replacement parts for the damaged parts can be ordered, and the container 1 can be easily disassembled at the location where the container 1 is used, the damaged parts can be replaced, and the container can be reassembled to repair the container 1 to an undamaged state. Furthermore, the container 1 can be repaired at the location where the container 1 is used, without having to be delivered to a factory or the like, and the delivery costs required for repairing the container 1 can be reduced.

[0110] Furthermore, as shown in Figure 16, the central portion in the longitudinal direction of the lower frame cover 14 attached to the left and right side surfaces of the lower frame 11 is configured to form a gap between it and the frame that constitutes the lower frame 11.

[0111] This is because the gripping parts 31a for operating the container 1 shown in Figure 12 are attached to the left and right side surfaces of the container 1, and when the container 1 is pushed and moved by gripping the gripping parts 31a, the lower frame cover 14, which is likely to come into contact with facilities or objects first, is deformed to act as a cushion.

[0112] The lower frame cover 14 can also be easily replaced with a new lower frame cover 14 by disassembling the container 1 in the disassembly step S10, thereby allowing the container 1 to be used safely and reducing damage to the locations and facilities where the container 1 is traveling.

[0113] In this embodiment, in the column mounting step S4 and the panel mounting step S5, the column 20 is mounted to the lower frame 11, and then the column 20 is inserted into the panel 30 and mounted thereto. However, the column 20 may be mounted to the panel 30 in advance as a single unit, and then mounted to the lower frame 11.

[0114] Specifically, the four pillars 20 are inserted into the insertion portions 32 of the two panel portions 30 in advance, and the pillars 20 are temporarily fixed to the panel portions 30 at a predetermined position where the mounting holes 24 of the lower hollow portions 23 of the pillars 20 are exposed, thereby integrating the pillars 20 and the panel portions 30.

[0115] As a method of temporary fastening, for example, separate threaded holes or mounting holes for temporary fastening may be provided at predetermined positions on the column portion 20 and the panel portion 30 and fastened using fastening members, or the column portion 20 may be temporarily fixed to the panel portion 30 with adhesive tape or the like.

[0116] Then, the convex portion 12 of the lower frame 11 is inserted into the lower hollow portion 23 of the column portion 20 that is temporarily fixed to the panel portion 30, and then a fastening member is inserted into the mounting hole 24 of the lower hollow portion 23 of the column portion 20 and fastened to the female screw hole 12a of the convex portion 12, thereby fixing the column portion 20 integrated with the panel portion 30 to the lower frame 11. Then, the temporary fixation is released.

[0117] This reduces the number of steps required to assemble the container 1 compared to the case in which the pillars 20 are attached to the lower frame 11 and then inserted into the panel sections 30, as in this embodiment. Furthermore, there is no need to raise the panel sections 30 to a position higher than the pillars 20 attached to the lower frame 11, so the container 1 can be assembled safely and easily.

[0118] Furthermore, by attaching the pillars 20 to the panel portions 30 in advance and integrating them during the packing step S1, the packed container 1a can be made even more compact by the volume occupied by the pillars 20.

[0119] The configuration of the container 1 shown in this embodiment is an example. As long as the container 1 can be packaged, can be assembled and disassembled at the delivery and use location, and can deliver dish baskets and food containers containing tableware between the food service center and the eating location, components may be added or removed. For example, it is possible to add a panel to the interior of the container 1, or to add or remove the configuration of the right door 60 and the left door 70. [Explanation of symbols]
