Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet that is received by a forklift and used for carrying loads.

[0002]

2. Description of the Related Art As a conventional pallet of this type, a pallet made of cardboard is known. An example of this is shown in FIGS. 9 and 10, which will be described below with reference to the drawings.
Is a bottom plate made of a corrugated board, and 2 is a leg which is placed on the bottom plate 1 and fixed to the bottom plate 1 by an adhesive. The leg 2 is formed by winding the corrugated board into a tubular shape (paper tube) and setting it to an appropriate length. The cut one is used. Reference numeral 3 denotes a top plate made of a corrugated board which is placed on the leg body 2 so as to be located right above the bottom plate 1 and fixed to the leg body 2 with an adhesive.

[0003]

However, the pallet made of corrugated cardboard having the above-mentioned structure is weak in strength because the top board 3 is a corrugated board, and in order to increase the strength, the top board 3 is used.
However, even if it is configured by using the composite corrugated board, there is a problem in that the top plate 3 is distorted between the legs 2 due to the weight of the transported object from above and the pallet is deformed.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a transportation pallet in which distortion of the top plate due to the weight of the object to be conveyed from above is suppressed.

[0005]

In order to solve this problem, the present invention provides a bottom plate, a leg member mounted on the bottom plate and fixed to the bottom plate by an adhesive, and an adhesive member mounted on the leg member. In a corrugated board pallet comprising a top plate fixed to legs, the top plate is composed of at least three layers of plate portions that are foldably connected to each other, and the plate is connected to the connection portion of the plate portion for bending. The gist of the present invention is to provide a narrow plate portion.

With this configuration, in the corrugated board pallet, the top plate is composed of at least three layers of plate portions which are connected to each other in a freely bendable manner, and the connection part of the plate portions is provided with a narrow plate portion for bending. Since it has many ridges, even if a large weight of the transported object is applied from above the top plate,
The top plate has sufficient strength to withstand its weight and can suppress distortion and deformation of the top plate.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. First, the first embodiment shown in FIGS. 1 to 4 will be described. 11 is a bottom plate made of a corrugated board, 12 is a leg body mounted on the bottom plate 11 and fixed to the bottom plate 11 by an adhesive. The leg 12 is formed by winding a corrugated board in a tubular shape (paper tube) and cutting it to an appropriate length as in the conventional example. Reference numeral 13 denotes a top plate made of a corrugated board placed on the leg 12 so as to be located right above the bottom plate 11 and fixed to the leg 12 with an adhesive.
Specifically, this top plate 13 is a plate portion having the same size as the bottom plate 11.
14, a plate portion 15 continuously provided on both sides of the plate portion 14 and having a width approximately half that of the plate portion 14, and a plate portion 15 and a plate portion 14 continuously provided to the respective plate portions 15.
A plate portion 16 sandwiched between the plate portion 14 and the plate portion 15 and fixed to the plate portion 15 with an adhesive, and further between the plate portion 14 and the plate portion 15 and between the plate portion 15 and the plate portion 16. The plate portion 15 and the plate portion 16 are provided with narrow plate portions 17 and 18 for bending. 19 is a curved line. The folding curve 19 is provided so as to face the same direction as the length direction of the step (wave) of the top plate 13. FIG. 4 shows a completed state of the pallet, and the plate portions 15 at the upper end, which are continuously provided on both sides of the plate portion 14, are configured to be close to each other at the center of the top plate 13 in the width direction.

In the above construction, the pallet has three top plates 13.
It is composed of the plate portions 14, 15 and 16 of the layers and has a narrow width for bending the plate portions 15 and 16 between the plate portions 14 and 15 and between the plate portions 15 and 16. Since it has many ridges with the plate portions 17 and 18, even if a large weight of the transported object is applied from above the top plate 13, the top plate 13 has strength enough to withstand the weight, It is possible to suppress distortion and deformation of the top plate 13.

Next, a second embodiment shown in FIGS. 5 to 8 will be described. In the first embodiment, the top plate 13 is used.
A plate portion 14 having the same size as the bottom plate 11, a plate portion 15 continuously provided on both sides of the plate portion 14 and having a width approximately half that of the plate portion 14, and each plate portion
As a configuration including a plate portion 16 connected to the plate portion 15 and sandwiched between the plate portion 15 and the plate portion 14 and fixed to the plate portion 14 and the plate portion 15 with an adhesive, the size is the same as the bottom plate 11 when viewed from above. However, in the second embodiment, the top plate 13 and the plate portion 20 that is approximately half the size of the bottom plate 11 and the plate portion 20 that is connected to one side of the plate portion 20 are provided.
And a plate portion 21 that has the same size as that of the plate portion 20 and is fixed to the plate portion 20 by an adhesive agent, and a plate portion 21 that is continuously provided on the other side of the plate portion 20 and that has the same size as the plate portion 20 and that overlaps the plate portion 21 The plate portion 22 fixed by the agent is provided. More specifically, the plate
A plate part is provided between the plate part 20 and the plate part 21 and between the plate part 20 and the plate part 22.
21 and the plate portion 22 are provided with narrow plate portions 23 and 24 for bending. 25 is a curved line. The two top plates 13 configured in this manner are placed side by side on the leg body 12 by an adhesive.
However, in the second embodiment, a plate 26 made of a corrugated board of the same size as the bottom plate 11 is fixed to the upper end of the leg 12 by an adhesive in the second embodiment. The top plate 13 is fixed on the plate 26 with an adhesive. The rest of the configuration is the same as that of the first embodiment, and it is possible to provide a pallet provided with the top plate 13 that can withstand the heavy weight of the transported object.

Incidentally, as described in the first embodiment, the folding curves 19 and 25 may be oriented in the same direction as the length direction of the step (wave) of the top plate 13, but the step ( You may make it face a direction orthogonal to the length direction of a wave.

[0011]

As described above, according to the present invention, in the pallet made of corrugated cardboard, the top plate is composed of at least three layers of plate portions that are foldably connected to each other, and the plate portions are connected to the connection portions for bending. Since it has a narrow plate part and many ridges, the top plate has enough strength to withstand the heavy weight of the transported object from the top plate. Distortion and deformation can be suppressed.
