2. Description of the Related Art Conventionally, a method of using a box pallet, a post pallet, or a double-sided type flat pallet has been adopted for stacking multiple pallets each carrying a load, and sometimes a multi-tier rack. There are cases where single-sided or double-sided flat pallets are stored in, but until now,
There was no single-sided flat pallet that could be stacked in multiple stages using only pallets.

SUMMARY OF THE INVENTION According to the present invention, a pallet leg is formed on the upper surface of a pallet, with two straight lines that are orthogonal to the center point of the upper surface and parallel to the peripheral edge of the upper surface as axes of symmetry. The present invention relates to a rectangular single-sided flat pallet having a structure in which deep recesses are arranged at symmetrical positions, and a method for stacking loads in multiple stages by forming a set of two pallets. It is a thing.

[0004]

A square single-sided flat pallet, on the upper surface of which is formed a leg block which is recessed in a shallow plane shape, on two straight lines which are orthogonal to the center point of the upper surface and parallel to the peripheral edge of the upper surface. With respect to each other, each of the block planes is evenly divided into four divided planes by two straight lines orthogonal to each other at the center point of the plane, and among the four divided planes, a corner is contacted at the center point. The two surfaces keep the planar shape as they are as shallow recesses, and the other two surfaces that are also in contact with the corner at the center point are formed with deep recesses to form pallet legs. The deep concave portion and the shallow concave portion of the leg block are symmetrical with respect to two straight lines which are orthogonal to the center point of the pallet upper surface and parallel to the peripheral edge of the upper surface. The deep concave portion and the shallow concave portion are symmetrical with respect to each other. The pallet legs are configured by being placed in the position.
The horizontal top surface of the load mounted on the top surface of the pallet is covered with the top surface of the pallet with the top surface turned downward so that the legs are oriented upwards so that the top surface of the load is horizontal. Cover with. A peripheral wall for locking, which is slightly higher than the upper surface, is provided on the peripheral edge of the upper surface of the pallet.

[0005]

[Function] The horizontal top surface of the load mounted on the upper surface of one pallet is covered with the upper surface of the other inverted pallet facing downward, and the load is further mounted on the pallet leg portion facing upward. When the downward legs of the pallet are placed, due to the mutual relationship between the positions of the deep recesses and the positions of the shallow recesses that form the leg block, the upward legs and the downward legs are in contact with each other on their side surfaces or the like. The four lower legs are formed in one block by adjoining each other and the lower edge faces of the legs contact the lower edge faces of the shallow recesses of the leg blocks. By forming the blocks, the pallets stacked in multiple stages are connected to each other, so that the pallets act stably against external forces such as vibration and upper load. Further, the peripheral wall for locking, which is provided on the peripheral edge of the upper surface of the pallet and is slightly higher than the upper surface, prevents the load from laterally deviating from the upper surface and stabilizes multi-tiered stacking. The shallow upper surface reinforcing grooves, which are formed between the blocks on the upper surface of the pallet, are arranged parallel to the peripheral edge of the pallet, the shallow upper surface reinforcing grooves are arranged diagonally, and the other branched shallow upper surface reinforcing grooves form the legs. Reinforces the strength of the pallet with deep recesses.

Are arranged in symmetrical positions.

A peripheral wall 9 slightly higher than the upper surface 1 of the pallet is provided on the upper peripheral edge 4 so as to be inclined slightly outward and an upper edge 17 of the peripheral wall is attached to the upper surface.

Between the leg blocks 2, a large number of shallow upper surface reinforcing grooves 14 arranged in parallel with the upper surface peripheral edge 4 and shallow upper surface reinforcing grooves 15 arranged along a diagonal line are formed, and in addition, a branched shallow upper surface reinforcing groove is formed. 16 are formed in large numbers.

In FIG. 6, two sets of multi-stage stacking type transportation pallets according to the present invention are used as a set, and a load 2 is loaded on a floor 20.
An example of two-stage stacking by the pallet of the present invention in which No. 1 is mounted is shown. The horizontal top surface of the load 21 mounted on the upper surface 1 of the pallet 22 is covered with the upper surface of the inverted pallet 23, and the leg portion 19 of the pallet 24 having the load 21 similarly mounted on the leg portion 19 facing upward. By putting 19
The four legs 19 form a set, and the side faces 12 of each leg are joined together.
Are close to each other, and the lower edge surface 11 of the leg portion is the lower edge surface 13 of the shallow recess.
One block 10 is formed by contacting with each other. Nine blocks 10 as many as the leg blocks 2 are formed there. Further, the peripheral wall 9 for locking is close to the top side surface and the bottom side surface of the load 21. The top surface of the second-stage load 21 is covered with the upper surface of the inverted pallet 25. By repeating this method of use, a multi-stage stack of three or more stages can be obtained.

In the present embodiment, the present inventor has already disclosed in
The pallets of the present invention are formed by vacuum molding or compression molding by heating a synthetic resin rectangular sheet proposed in No. 102548, JP-A-4-215942 and Japanese Patent Application No. 4-147978.

EFFECTS OF THE INVENTION The multi-stage stacking type transportation pallet and the method of using the same are the flat pallets having a rectangular single-sided shape, but the vibration and the like are caused by the block and the peripheral wall in which four legs are combined. Enables stable multi-stage stacking against external force. If the load on the pallet of the present invention is a small number of large packages, or if the load is a plurality of small packages, the present invention can be used if there is a simple lanyard as much as possible with an automatic lanyard. The stabilizing effect of multi-tiered stacking by the method is greater. The ability to stack in multiple stages without a rack is convenient for storage in the warehouse or truck transportation, etc.When returning empty pallets, it is possible to make two sets as a set, and the same level of bulk as in the case of conventional pallets. It is stored. It is possible to obtain effects such as reduction of physical distribution costs.
