Reference numeral 17 denotes a hand-operated cut formed on the lower surface of the bottom plate portion 11. Moreover, the support | pillar part 10 is formed in the hollow shape by forming the reinforcing rib 18 in a grid shape.

  Further, as shown in the perspective views in FIGS. 4 and 5, respectively, the intermediate plastic molded bodies 2a and 2b are formed inwardly from the I-shaped column portion 20 and the lower portion of the column portion. A horizontally projecting bottom plate portion 21 is formed, and a convex portion 22 and a concave portion 23 that can be fitted to each other are formed on the upper surface and the lower surface of the column portion, and the inner edge of the bottom plate portion 21 is lowered in a step shape. A surface 24 is extended. In addition, the support | pillar part 20 is formed in the hollow shape by forming the reinforcing rib 25 in a grid shape. The corner plastic moldings 1a to 1d and the intermediate plastic moldings 2a and 2b can be molded from conductive plastic to prevent charging.

  On the other hand, each of the connecting rods 3a to 3d is formed into a rigid straight bar shape by a metal mold having an L-shaped cross section, and the long connecting rods 3a and 3b and the short connecting rods 3c and 3d are formed by the cutting length. It is formed. The edge members 5a to 5d are narrower than the connecting rods 3a to 3d and are formed in a straight bar shape rigid with a metal mold having a L-shaped cross section. 5b and short edges 5c and 5d are formed. The bottom surface holding member 5f is formed by cutting a constant width band-like rigid metal member to the same length as the long connecting rods 3a and 3b.

  Then, the corner plastic moldings 1a to 1d are arranged at the four corners, and the connecting rods 3a to 3d are arranged so that the inside of the L shape faces inward, and the end portions of the corner plastic moldings 1a to 1d are arranged. As shown in FIG. 6, the connecting rods are connected to each other in a rectangular shape by being put on the bottom plate portion 11 and fixed by inserting screws 70 as shown in FIG. 6, and the intermediate portions of the long connecting rods 3 a and 3 b are intermediate. The plastic moldings 2a and 2b for parts are arranged, and the long connecting rods 3a and 3b are fixed to the bottom plate part 21 with screws 70. Similarly, the edge members 5a to 5d are placed on the support surface 14 of each corner plastic molding and the support surface 24 of both intermediate plastic moldings so that the inside of the L shape faces inward. The rims 70 are connected to each other in a rectangular shape by inserting and fixing the screws 70. As a result, a robust rectangular structural frame 7 is assembled.

  FIG. 6 shows the structural frame body 7 assembled in this way, the four band-shaped buffer members 4a to 4d set on the structural frame body, and one protective plate 6 in an exploded state. Each of the band-shaped buffer members 4a to 4d is cut to the same length as each of the connecting rods, and the protective plate 6 is made of an elastic plate formed into a rectangular shape with low foam plastic, and the protective plate By placing 6 on the edge members 5a to 5d, the protection plate 6 is surrounded by the edge members 5a to 5d, and the protection plate 6 is supported horizontally on the bottom of the frame body. The bottom surface holding member 5f is positioned transversely below the protective plate 6 by screwing both ends to the lower surfaces of the edge members 5c and 5d to prevent the protective plate 6 from drooping.

  Further, as shown in FIG. 7, the band-shaped buffer members 4a and 4b are arranged inside the long connecting rods 3a and 3b, and the band-like buffer members 4c and 4d are arranged inside the short connecting rods 3c and 3d. The plate-like object 8 is horizontally supported by placing the peripheral part of the rectangular plate-like object 8 (the peripheral part of the glass surface in the plasma display panel) on the buffer members 4a to 4d. In the case of this plasma display panel, since the projecting piece 80 projects horizontally outward from the upper part of the corner of the plate-like object, the projecting piece is placed on the locking base portion 15, The plate-like object 8 is fixed immovably by inserting a stop pin 82 into the through hole 81 formed in the protruding piece and the stop hole 16.

  Thus, in this plate-shaped article packing tool, the plate-like article 8 is supported horizontally, and the plate-like article packaging tool on which the plate-like article 8 is similarly supported is placed between the plastic molded body for each corner and the intermediate. As shown in FIGS. 8 and 9, the upper plate load is not applied to the lower plate-shaped object by fitting the protrusions 12 and the recesses 13 and the protrusions 22 and the recesses 23 of the plastic molded part. In addition, it can be stacked in multiple stages in a stable state. For this reason, the exclusive space for storage and transportation is reduced, and logistics costs can be greatly reduced.

  Further, when storing and transporting, as shown in FIG. 10, a buffer sheet (thickness of about 50 mm) 90 is laid on the bottom pallet 9, and the plate-like packing tool is stacked on the paper plate or the required number of steps. A rectangular cylindrical outer box 91 formed of plastic corrugated cardboard or the like is covered to surround the periphery, and the upper end opening is covered by covering the top pallet 92. By wrapping the entire surface in this way, dust, dust and the like can be prevented from entering the inside.

  The protective plate 6 is provided as necessary so that the flat plate is supported by the protective plate 6 even if the glass surface of the flat panel is bent. For this reason, it is possible to store and transport even a large display panel in a horizontal position (horizontal state) without any trouble by this plate-like material packing tool.

  The plate-shaped article packing tool configured as described above can easily cope with the size change of the plate-shaped article to be packed by changing the cutting length of the connecting rods 3a to 3d. In addition, the plastic molded body for the intermediate portion may not be used for a small plate-like material, and the support can be further stabilized by increasing the number of use of the large-sized plate-like material. Therefore, in the present invention, it is possible to pack from a small to a large plate by simply preparing a plastic part for a corner and a plastic part for an intermediate part in advance, thereby reducing costs.

  On the other hand, FIG. 11 and FIG. 12 show a plate-shaped object transport container dedicated to a flat panel such as a plasma display, and the container h made of plastic is integrally formed with a protrusion a on the lower edge of the inner peripheral surface. A prismatic support portion b is integrally formed at an appropriate pitch on the inner peripheral surface of the ridge, and a mounting piece d protruding at the same pitch on the outer peripheral edge of the flat panel c is placed on the support portion b. By doing so, the load of the flat panel c is supported by the support portion b. Thereby, the lower surface (glass surface) e of the flat panel c can be accommodated away from the bottom surface f of the container, and the lower surface e can be protected. In addition, g is a protective plate made of an elastic material made of foamed plastic that is disposed on the bottom surface f as necessary. Even in such a plate-shaped object transport container, dust and dust can be prevented from entering, and stacked in a required number to save storage and transportation costs. Since this plate-shaped material transport container is integrally formed of plastic, there is a disadvantage that only a certain size of the plate-shaped material can be accommodated, but the entry of dust and dust is prevented by stacking. The space can be used effectively.
