Description

[Detailed Description of the Invention] This invention relates to a cardboard pallet made of cardboard such as cardboard and used for carrying articles on a forklift.

2. Description of the Related Art Conventionally, lightweight and inexpensive corrugated cardboard pallets formed from corrugated cardboard sheets have been widely used as pallets for handling lightweight cargo.

However, as a product of this kind, there is a known
The cargo transport pallet disclosed in Publication No. 794 has a single cardboard board on which the cargo is placed, which has poor pressure resistance and is easily bent and damaged by loads.

In order to solve the above-mentioned problems, this invention provides a cardboard pallet that is lightweight and can be supplied at low cost by reinforcing the loading plate portion as a double plate.

The structure of this invention is made entirely of thick paper such as cardboard, and the loading plate on which the cargo is placed is reinforced with a double plate consisting of an outer and inner upper plate member, and the lower part of this plate is shaped like a tray with a space for inserting a forklift's claw. A lower plate member is fixed, and three rectangular cylindrical legs are fixed to the improvement plate member with a space between the lower plate member and the lower plate member for insertion of a forklift claw, and a plurality of flat plate-like legs are fixed at key points on the upper surface. A reinforcing plate is attached, and the lower plate member is provided with reinforcing and connecting side plates bent upward on four sides, one set of the side plates is formed with a forklift claw insertion hole, and the outer upper plate member is provided with a forklift claw insertion hole. is provided with reinforcing and connecting side plates bent on all four sides.

Hereinafter, embodiments of this invention will be described based on the drawings.

FIG. 1 is an exploded perspective view of the corrugated board pallet of this invention, which is divided into an upper plate member A, a lower plate member B, and an outer upper member C, all of which are made of thick paper such as corrugated cardboard.

In the improvement plate member A, leg members 2 are continuously provided on both edges of a rectangular loading plate 1, and the leg members 2 have narrow fold lines 3a parallel to each other along the edge of the loading plate 1. 3 b, 3 C
, 3d and 3e are provided.

These fold lines are sequentially bent from the outer fold line 3e, and the overlapping plates are joined with fasteners or the like to form legs 4 with a square cross section on the lower surface of the loading plate 1.

The two improvement plate members A are arranged in parallel so that the loading plate 1 forms a continuous plane, and the contacting leg 4 side plate surfaces 5 are fixed with adhesive or the like.

The claw of a forklift can be inserted into the space between the legs 4 of this improving member A.

In addition, a plurality of rectangular reinforcing plates 6 are attached to the main parts of the upper surface of the loading plate 1 to provide reinforcement when loading articles with protrusions. It is also possible to attach it to the upper surface of the loading plate 11 of the member C.

The reinforcing plate 6 is preferably made of strong fiber made by stacking cardboard and pressing it together.

The lower plate member B has narrow side plates bent upward on the four sides of a rectangular bottom plate 7 on which the legs 4 of the improvement plate member A are placed. , a plurality of insertion openings 9 into which forklift claws can be inserted are provided.

One set of side plates 10 is fixed to the side surfaces of the legs 4 on both sides of the improvement plate member A with an adhesive or the like.

The outer upper plate member C is provided with narrow side plates on the four sides of the loading plate 11 that overlaps the upper surface of the loading plate 1 of the improvement plate member A, and the side plates 12 of this left and right set are bent upward, and the lower plate It is fixed to the side plate 8 of member B with a stopper or the like to prevent the loaded articles from sticking out and to prevent damage to the articles due to collision with the claws of a forklift, and one set of side plates 13 is bent downward, Side plate 10 and legs 4 of the lower plate member B
It is fixed together with the side plate and fasteners.

The cardboard pallet according to this invention has the above-mentioned configuration, and all members are formed only from thick paper such as cardboard. The legs 4 are shaped like a box in which members C are fixed together using an overlapping stopper or adhesive, and are subjected to pressure.
The loading plate 1 has a plurality of plate materials stacked on top of each other, and the main parts of the loading plate 1 are reinforced by pasting strong reinforcing plates 6, etc., and side plates are provided to prevent the loaded articles from sticking out and being damaged by forklift nails. It is sufficiently durable for normal cargo handling operations.

In addition, it is more productive to manufacture than relatively simple rectangular members with a similar structure, and the pallets are lightweight, making it easy to carry empty pallets at transportation sites. It can be supplied at a lower cost and is more sanitary than others.
