And the rear crosspieces 2A and 2B between the upper ends of the rear vertical columns 2A and 2B.
Are linked. That is, the support members 8A, 8B have their front ends supported by auxiliary members 10A, 10B mounted inside the upper ends of the front vertical columns 1A, 1B, and their rear ends at the rear crosspiece 9A.
Supported at both ends. Then, as shown in FIG.
The width a of the supporting members 8A, 8B is set to be larger than the opening width b of the supported members 4A, 4B, and when the carrying tools loaded with the conveyed goods are stacked, the supporting members 8A, 8B are supported by the inclined surface 8a of the supporting members 8A, 8B. Even when the leg portions 4a on both sides of the members 4A and 4B are abutted and supported, and the upper transporting tool is placed while being shifted left and right, the upper transporting tool is centered by the action of the inclined surface 8a.

Further, on the rear end surfaces of the support members 8A, 8B, the restriction plates 11A, 11 for restricting the rearward movement of the upper-stage carrying tool at the time of storage.
B is installed. As shown in FIG. 2, the inner surface spacing l ₂ of the supporting members 8A, 8B is the outer surface spacing of the rear vertical columns 2A, 2B.
It is set larger than l ₁ . Therefore, this carrying tool is a box-shaped frame structure with the front and top surfaces open,
At the time of nesting, the upper carrying tool can be inserted from the front of the lower carrying tool as shown by the phantom line in FIG.

12A and 12B are side subposts that are detachably installed between the supporting members 8A and 8B and the side girders 3a and 3b of the bottom frame 3, and 13 is the inner crosspiece 9.
The rear subposts are detachably provided between the rear girder 3c of the bottom frame 3 and the bottom girder 3c, and these three subposts 12A, 12B, 13 prevent the articles carried on the bottom frame 3 from falling apart. It is also installed for the purpose of reinforcing the framework structure.

As shown in FIGS. 4 and 5, the mounting portions of the side subposts 12A and 12B are fixed to the mounting plate 14 protruding outward to the lower surface of the intermediate portion of the supporting members 8A and 8B. A side holding cylinder 15 into which the side subposts 12A and 12B can be fitted is hung on the lower surface of the portion. This is because the support members 8A and 8B are located above the bottom frame 3. Further, a locking tool 16 having locking claws 16b formed by bending the tip of the projecting plate 16a downward is fixed to the inner surfaces of the lower ends of the side sub-posts 12A, 12B. On the other hand, on the lower surface of the side girders 3a, 3b of the bottom frame 3 facing the mounting position of the side holding cylinder 15, a locking member 16 is engageable and disengageable.
7 is stuck. The locked member 17 includes a bottom plate 17a and a bottom plate 17a.
The front and rear plates 17b and 17c are formed in a channel shape by the front and rear plates 17b and 17c in which the front and rear of a are bent upward, and the upper ends of the front and rear plates 17b and 17c are fixed to the front and rear positions of the lower surfaces of the side beam members 3a and 3b, respectively. Therefore, by appropriately setting the lengths of the side sub-posts 12A and 12B, after inserting the upper ends of the side sub-posts 12A and 12B into the side holding cylinders 15 up to near the upper limit, the protruding plate 16a of the locking tool 16 is inserted. Is inserted between the front and rear plates 17b, 17c of the locked member 17, and the side subposts 12A, 12B are pulled downward, whereby the locking member 1
It is possible to mount the side subposts 12A and 12B by supporting the protruding plate 16a of the locking tool 16 on the bottom plate 17a of 7 and locking the locking claw 16b to the inner edge of the bottom plate 17a.

As shown in FIG. 6, the mounting portion of the rear sub-post 13 is
A rear holding cylinder 18 into which the upper end of the rear sub-post 13 can be fitted is hung on the lower surface of the middle portion of the inner cross member 9, and the lower end of the rear sub-post 13 is located at a position opposite to the rear holding cylinder 18 on the outer surface of the rear girder 3c of the bottom frame 3. The support cylinder 19a with the receiving plate 19b into which the bracket can be fitted is fixed. Therefore, by setting the rear sub-post 13 to an appropriate length, the upper end of the rear sub-post 13 is inserted near the upper limit of the rear holding cylinder 19, and the lower end is made to face the support cylinder 19a and the rear sub-post 13 is pulled down. This allows the lower end of the rear sub-post 13 to be supported by the support cylinder 19a,
The upper end portion can be attached by engaging the holding cylinder 18.

A square pipe body is used as the frame component member of the above embodiment.

 Next, a method of using the above-mentioned transportation tool will be described.

If you don't need subposts 12A, 12B, 13
It is used with 12A, 12B and 13 removed, and nesting is done when stacking or not in use. That is, this carrying tool carries the goods to be carried on the bottom frame 3 and carries them by a forklift, a truck, or the like. However, when the goods are carried or stored in a loaded state, as shown by phantom lines in FIG. In addition, the space can be effectively used by stacking the layers vertically. Ie up and down 2
When stacking in steps, use the forklift to move the upper carrier to the lower vertical column 1A, 1 in front of the landed lower carrier.
Lift slightly higher than the upper ends of B, 2A, 2B and move to the left and right to position the front part of the lower supporting members 8A, 8B and the rear parts of the upper supported members 4A, 4B so that they can fit together, and the upper carrying tool By pushing backward to lower the upper supported members 4A, 4B at positions where they abut the regulation plates 11A, 11B, and fit the supported members 4A, 4B of the upper carrying tool to the supporting members 8A, 8B of the lower carrying tool. Let me support you. At this time, as shown in FIG. 5, the lower supporting members 8A, 8B are formed in a mountain-shaped cross section, and the upper supported members 4A, 4B are formed in a U-shape in which the bottom surface is open and are supported. The width a of the members 4A and 4B is the supported members 8A and 8B.
Since it is smaller than the opening width b of the support member 4A, 4B
The lower end a is brought into contact with the inclined surfaces 8a of the support members 8A and 8B to be centered.

When the above-mentioned carrying tool is not used for carrying or stocking a conveyed product, nesting can be performed with a low bulk. That is, at the front part of the landing lower carrying tool, the upper carrying tool to be nested is lifted to a position slightly higher than the upper ends of the locking plates 12A, 12B of the lower carrying tool. Then, from between the front struts 1A and 1B of the lower carrying equipment to the rear struts 2A and 2B of the upper carrying equipment.
And the bottom frame 3 and the supported members 4A, 4B are pushed in, and the upper front pillars above the locking plates 12A, 12B of the lower front pillars 1A, 1B.
1A and 1B face each other and descend. Then, the rear columns 2A, 2B of the upper carrying tool and the supported members 4A, 4B can be landed on the bottom frame 3 of the lower carrying tool and nested as shown by phantom lines in FIG.

Side subpost 12
The A, 12B and the rear sub-post are mounted between the support members 8A, 8B and the bottom frame 3 and between the back cross member 9 and the bottom frame 3, respectively, to carry and store the transported object. At this time, each sub-post 12A, 12B, 13
Is attached to the outside of the bottom frame 3, especially the side subposts 12A,
Since 12B is located substantially at the same position in the front-rear direction as the front vertical columns 1A, 1B, the frontage width L of the carrying tool is not limited by the side posts 12A, 12B. Further, even when the conveyed items are in a loaded state, the side posts 12A and 12B are outside the front width L and the locking tool 16 does not contact the conveyed items, so that they can be easily attached and detached. Further, the rear post 13 can be similarly operated. When nesting when not in use, remove all subposts 12A, 12B, 13 of the carrier other than the lowest stage.

As described above, according to the present invention, since the sub-post is mounted on the outer side of the bottom frame between the support member and the bottom frame, the front width between the front vertical columns is not narrowed. The effective floor surface is not restricted. Moreover, since the locking tool at the lower end of the sub post can be engaged and disengaged from the outside, and the sub post does not contact the inner surface or the inner surface of the sub material and the locking tool does not contact the transported material, the transported material is loaded on the bottom frame. Even inside, the subpost can be easily attached and detached.
