DETAILED DESCRIPTION OF THE INVENTION
As shown in an exploded perspective view of FIG. 1, an enlarged exploded perspective view of the main part of FIG. 2, a development view of the foot clogs of FIG. 3, and an enlarged vertical sectional view of the main part showing the assembled state of FIG. It is a paper pallet formed of cardboard (or paperboard) to be inserted into 60, and may be placed under the box 60, or the article may be placed directly without the box 60. First, an outline of the configuration of the paper pallet is shown. The bottom plate 1 is inserted into the bottom of the box 60. On the bottom plate 1, a plurality of foot clogs 10 are arranged and fixed substantially in parallel. Reinforcement frame 40 assembled in a lattice shape with foot clogs 10 is attached. The upper plate 50 is attached on the foot clogs 10 and the reinforcing frame 40 assembled in a lattice shape. The paper pallet having the above-described configuration can be used without using the bottom plate 1 and only having the foot clogs 10 and the reinforcing frame 40 assembled in a lattice shape.
[0009]
Hereinafter, each configuration will be described in detail. The box 60 is formed to be foldable. The bottom plate 1 inserted into the bottom of the box 60 is a rectangular flat plate made of cardboard or cardboard.
[0010]
The foot clog 10 to be mounted on or attached to the bottom plate 1 is formed from a single rectangular plate 11 shown in FIG. Four parallel folding lines (chain lines) 12 are drawn that connect the opposing sides with a straight line and bend them inward. In the central piece 11a of the rectangular plate, four cutout holes 13 and four cutout holes 14a that become the cutout recesses 14 when the plate 11 is folded into a prismatic shape are intermittently provided in parallel with the folding line 12.
[0011]
The cutout hole 13 is provided in a direction orthogonal to the folding line 12, and the length of the cutout hole 13 is the width of the inner surface when the foot clog 10 is horizontally installed. A fold line (chain line) 15 passing through both ends of the cutout hole 13 and parallel to the fold line 12 is bent inward.
[0012]
When the plate 11 is bent into a prismatic shape to form a foot clog 10, the cutout recess 14 fits a part of the reinforcement frame 40 when the foot clog 10 and the reinforcement frame 40 are assembled in a lattice shape as shown in FIG. 1. It is a recess. A first fixing member 20 is formed in the notch recesses 14 at both ends, and a first fixing member 21 is formed in the two notch recesses 14 in the center. These are bent at the upper end of the notch recess 14 shown by the dotted line in FIG. The bending direction of the first fixing members 20 and 21 is a direction orthogonal to the folding lines 12 and 15. The widths of the first fixing members 20 and 21 are slightly longer than the width of the inner surface of the foot clog 10 so that the inner wall surface of the foot clog 10 can be strongly pressed when folded into the foot clog 10. A U-shaped notch 22 is provided at the tip of the first fixing member 20. The tip of the first fixing member 21 is linear, but a notch similar to the U-shaped notch 22 may be formed.
