[0003]

In the above-mentioned container, all of the front and rear panels and the left and right panels are disassembled from the bottom panel and laminated on the upper surface of the bottom panel. Therefore, when the container is reused, it is necessary to assemble each of the front, rear, left and right panels with respect to the bottom panel, and to engage and connect adjacent panels with corner fittings. In addition, each time a container is stored in the container, the collection set must be bolted to the four corners of the upper surface to enable stacking of the container. It also takes a lot of time and effort to make a component unit.

As described above, when container components are laminated to form a component unit, collection set fittings are erected at the four corners of the bottom panel. It is merely a plug-in engagement from above. Therefore, when the stacked units are stacked, there is room for improvement in that the vertical unit rows are easily wobble and lack stability.

An object of the present invention is to make it possible to easily assemble the front and rear panels and the left and right panels with respect to the bottom panel, and to stack the front, rear and left and right panels on the upper surface of the bottom panel when not in use to form one component unit. SUMMARY OF THE INVENTION It is an object of the present invention to provide a transport container that can be compactly packed as a package, and thus can significantly save the space required for storing and transporting the container when not in use. SUMMARY OF THE INVENTION An object of the present invention is to enable one of the front and rear panels and the left and right panels to be folded and stored in a bottom panel in an assembling type container, so that a series of operations for assembling the container and folding and storing are reduced. The goal is to ensure that the process can be performed quickly and without error.
Another object of the present invention is to provide a transport container which can stably stack containers or folded container parts without wobbling, and thus can reliably prevent collapse of the load during transportation.

One of the front and rear lock rods 35 is inserted into and engaged with a lock hole 36 provided in the column 17, and the other lock rod 35 is similarly locked and engaged. The remaining left and right panels 3 are fitted into the left and right base frames 6 in the same manner, and furthermore, the front and rear locking rods 35 are respectively engaged with the front and rear columns 17 by lock engagement. When the front and rear panels 2 are assembled to the corner posts 8 in advance, the front and rear panels 2 are respectively erected, and the lower portions thereof are fitted into the front and rear base frames 5, and the pins 23 are inserted into the recesses 24 in the same manner as described above. Can be held upright simply by engaging with it.

When the container is not used, the above-mentioned panels are laminated on the upper surface of the bottom panel 1 to form a component unit. First, the lock bars 35 on the front and rear sides of one of the left and right panels 3 are respectively unlocked to release the lock engagement state with the front and rear panels 2, and in this state, the left and right panels 3 are pulled out from the left and right base frames 6. Similarly, the other left and right panels 3 are separated from the front and rear panels 2 and the bottom panel 1. Next, the front and rear panels 2 at the rear of the container (the side where the undulation shaft 21 is lower) are lifted along the corner posts 8, and the lower part thereof is extracted from the front and rear base frames 5, and the pins 23 are simultaneously extracted from the concave portions 24. In this state, the front and rear panels 2 are tilted inwardly, and the engagement recess 20c at the lower end of the undulating groove 20 is engaged with the shaft portion 21c of the undulating shaft 21 as shown by the imaginary line in FIG. As a result, the front and rear panels 2 are received by the left and right base frames 6 of the bottom panel 1 and maintain a horizontal posture. Similarly, the front and rear panels 2 in front of the container
Is separated from the front and rear base frames 5, tilted in an inward shape, and stacked on the upper surface of the front and rear panels 2 folded earlier.

After the pair of front and rear panels 2 are folded and laminated as described above, the pair of left and right panels 3 are sequentially laminated on the upper surface thereof, so that the container assembled in a rectangular box shape can be occupied in the occupied space. Compact as a small component unit. The component units are stored or transported in a warehouse or the like in a state of being stacked in multiple stages. In this stacked state, as shown in FIG. 6, the female post 10 of the upper part unit is received by the corner post 8 of the lower part unit, and the upper floor contact frame 1 is received.
A pair of front and rear panels 2.2 and right and left panels 3.3 are housed between the lower panel 1 and the lower bottom panel 1.1. In other words, the upwardly protruding dimension of the corner post 8 may be set to be larger than the total thickness of the four panels 2 and 3 stacked on the bottom panel 1.

The panel lock body 33 of the above embodiment is constituted by using the lock rod 35 and the lock hole 36 which engage with each other as lock elements, but this is not necessary. For example, a hook is provided on the column 17 side, and the front and rear panels 2 can be pulled toward the left and right panels 3 by a lever link type latch which is engaged and disengaged from the hook, so that adjacent panels can be locked and fixed. . Further, as the panel lock body 33, a pin that simultaneously engages with the corner post 8 and the column 17,
A bolt or the like screwed into 17 can be used. When the support 17 is formed as a dedicated part for each of the right hand and the left hand, it is not necessary to form the undulating groove 20 in a longitudinally symmetric shape.
