At the bottom of both ends of the back panel body 10 are shown figures 11 to 13.
As shown in the figure, a plate 20 is fixed to the rear wheel via rivets 22 or the like. Here, the rear wheel mounting plate 20 has a common shape to ensure compatibility, and before fixing it to the bank panel body 10, a rotation stop pin 28 is installed on the left side of the left rear wheel mounting plate 20. A rotary connecting pin 27 is installed upright on the right side of the plate 20 for mounting the right rear wheel.

To attach the wheels after rain, the rear axle 11 is attached to the plate 20 by inserting it into the locking piece 23 and tightening the bolt 33.

In FIGS. 15 to 17, both side panel bodies 40 are
A front wheel mounting plate 5o is fixed to each front end.

Here, when mounting the front wheel, the plate 50 has a common shape for compatibility, and the front wheel is fixed to the side panel body 40.
A locking plate 56 is attached to each position.

To attach both front wheels, the front wheels 41 are attached to the plate 50 by inserting them into the locking pieces 53 or tightening the bolts 61.

When connecting the bank panel body 10 and the left side panel body 40, the left rear wheel is attached by engaging the pin hole 49 with the detent pin 28 provided upright from the plate 2o.

Then, by connecting the adjacent vertical rod portions 12b and 42b with the connecting tool 70, the two are integrated at right angles.

Further, when connecting the bank panel body 10 and the right side panel body 40, the right rear wheel is attached by engaging the pivot hole 48 with the rotary connecting pin 27 which is set up from the plate 20. By connecting the adjacent vertical rod portions 12b and 42b with the connecting tool 70, both are connected to be relatively rotatable around the pin axis of the rotary connecting pin 27.

As mentioned above, when connecting via the connector 70, first, as shown by the imaginary lines in FIG. 2, both vertical rod portions 12h are connected.

Connecting members 71A and 71B are opposed to each other on the outside of 42b. Then, the two front flat cylindrical portions 73A, 73B and the two cast half cylindrical portions 74A, 74B are brought close to each other and fitted onto the vertical rod portions 42b, 12b, respectively, as shown by solid lines in FIG. At this time, the back side locking pin 16 is positioned in the locking holes 79A, 79B, and the front half-cylindrical portions 73A, 73
A side locking pin 46 is located below B. Then, as shown in FIG. 5, by using both coupling holes 75A and 75B and integrating both coupling plate parts 72A and 72B with rivets (bolts and nuts) 80, both panels are connected via the connecting tool 70. The desired connection between bodies 10.40 can be made. Note that when integrating with the rivet 80, the connecting member 71A,

Fit it onto b. And both coupling plate parts 124A, 124
The base side of the member 122 is inserted into the receiver between B and the stepped portions 129A and 129B are used for positioning. Next, the matched coupling holes 125A and 125B and the through hole 130A,
By driving the rivet 133 between the rivets 130B, the flange 121 and the receiver member 122 are integrated, and thus the second holder 20 can be attached. Note that the second holder 120 is attached above the side locking pin 46.

The article carrier 1 assembled as described above is constructed by opening the right side panel body 41 perpendicularly to the pack panel body 10, and horizontally swinging the heath panel body 85 through the hinge device 2. Loading and unloading of the load can be carried out by placing the load on the lower frame 43 of the side panel body 40 and locking the lifting device 90. At this time, the locking device 90 moves the lock pin 95 out and out against the tension spring 97 as shown by the imaginary line in FIG. 21, and the first stopper 98 passing through the through hole 93A It is strongly engaged with the edge 99 by the biasing force of the spring 97 in the diagonal direction. As described above, by horizontally swinging the base panel body 85, the lock hole 55 of the locking plate 56 is closed.
The lock pin 95 faces the. In this state, insert your hand under the base panel body 85 and move the operating portion 95m of the lock pin 95 toward you against the tension spring 97.

As a result, the first stopper 98 comes off the edge 99, and the first lock pin 95 projects outward due to the urging force of the tension spring 97, and the locking plate 56 is moved as shown by the solid line in FIG. 21 and in FIG. Engage with lock hole 55.

Note that the second stopper 100 protrudes from the outer side plate portion 92B.
It is regulated by coming into contact with.

When loading and unloading cargo, both holders 100°120
is raised, the locking recesses 117 and 126 are spaced apart from the side locking pin 46 as shown by the imaginary line in FIG. By being lowered, as shown by the imaginary lines in FIG. 25, there are fewer protrusions at the entrance formed by both vertical rod portions 42b. After loading the cargo, both holders 11
Return 0.120 to its original state, 1'- and Fig. 24. The locking portion 105b of the stay 105 is engaged with the locking hole 127 as shown by the solid line.

Note that when loading and unloading cargo, it is not necessary to use both holders 1.
10.120 does not need to be rotated. In addition, by forming three locking recesses 117° and 126 for one side locking pin 46, it is possible not only to engage in both rotated positions, but also to hold the first holding Q 110. Attach it to the right side panel body 40 and attach the second holder [20] to the left side.

When a load is being transported by the article transport device 1, each panel body 10, 40 has sufficient bending strength, so that it will not be deformed by the internal pressure of the load.

In other words, since the horizontal members 15 and 45 have a channel-shaped cross section, sufficient bending strength can be obtained without significantly increasing the weight or size. Welding to the vertical rod portions 12b, 42b can be performed at a sufficient distance along the recesses 68, 69. Further, the folded portions 66 and 67 can further improve the bending strength of the cross members 15 and 45 by 6ζ, and the arcuate shape of the folded portions 66 and 67 allows for smooth contact and sliding contact of the load.

When the article carrier l is unused after being transported as expected and unloaded, the stay 105 is first removed from the second holder 120. Then, as described above, after the opening pin 95 is pulled out against the tension spring 97, the base panel body 85 is rotated upward via the hinge device 2 to be aligned with the back panel body 1o. Then, the rod pin 95 is moved to protrude again to protrude to the rear of the vertical rod portion 42b attached later.

Next, the right side panel body 40 is rotated around the pin axis via the connector 70 and the rotary connecting pin 27, and is brought along the bank panel body IO side. Thereby, it can be folded into an L shape when viewed from above and stored.

Effects of the Invention According to the present invention having the above configuration, when the bank panel body and the side panel body are connected via the connecting tool, first, the connecting members facing each other on the outside of both vertical rod portions are brought close to each other. , both front semi-cylindrical parts and rear semi-cylindrical part can be fitted onto the vertical rod parts, and by integrating the reconnection plate part, the connection between the two panel bodies can be made via the connecting tool. The desired connection can be made. When stopping like this,
The rear end side of the coupling plate part can be positioned by a back side locking pin locked in the locking hole, and the front end side can be positioned by one front semi-cylindrical part by a side side locking pin. The other front semi-cylindrical portion can be positioned with respect to one of the two through the abutment surface, so that the connection can be easily and accurately performed without any positional deviation. The connecting position can always be kept in the fixed position by engaging the locking pin, and it will not move downward due to vibrations during use, so the rotation of the cylindrical body can always be performed smoothly. .
