Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is applied to products in factories, warehouses, etc.
The present invention relates to a pallet used for loading and unloading articles such as semi-finished products, and further relates to an assembly type flat pallet suitable for storing and transporting pallets.

[0002]

2. Description of the Related Art Conventionally, as a pallet 24 used for loading and unloading work in a factory or warehouse, as shown in FIG. 6, a wooden flat pallet composed of a deck board 22 and a digit 23 is used. Materials made of metal or metal have also been used. Each of these has a structure having a space between the upper deck board and the lower deck board in which a forklift claw can be inserted. Since the wooden pallet was assembled by nails and the steel pallet was assembled by bolts and nuts and welding, disassembly and use was impossible. Moreover, since the resin pallet is integrally molded, it cannot be disassembled. Therefore, since each of the flat pallets has a thickness of 100 mm or more, much space is required for collecting, storing or transporting empty pallets.

[0003]

In the conventional flat pallet described above, since a large amount of space is required for transporting and storing empty pallets, even though the pallets are used in a large amount for cargo handling work on the premises, they are transported. Was not used much for. In this way, it is clear that transportation with cargo loaded on pallets will greatly contribute to the rationalization of logistics, but it will be costly to store and recover empty pallets after transportation, and transportation by pallets will not spread. It was one of the factors.

The present invention has been made in order to eliminate the above-mentioned problems, and an object thereof is to use the same method as a conventional flat pallet at the time of use, but it is less necessary at the time of collection or storage. It is possible to stack so that space is enough.

[0005]

SUMMARY OF THE INVENTION The present invention provides two pallet bodies having a plurality of cavities protruding blocks.
A block provided on each pallet body is rotatably connected by a hinge so that the bottom surfaces of the blocks come into contact with each other, and a hook provided on the back surface of one pallet body engages a clamp provided on the back surface of the other pallet body. It provides a stopped pallet.

[0006]

Since the pallet of the present invention has the above-mentioned structure, the upper and lower pallet bodies form a flat pallet by connecting the hook and the clamp. Further, by removing the clamp and opening the upper pallet main body around the hinge, the pallet can be developed into a sheet shape. Therefore, when stacking sheet-shaped pallets, the cavities of the blocks provided on the pallets are formed with a slope,
The upper and lower blocks are inserted into each other to fit in, and the bulkiness is reduced. Since the hinge has an angle of 45 degrees or more and the lower side of the hinge is open, the hinge of the lower pallet is inserted under the hinge of the upper pallet.
Furthermore, since the clamp is folded and stored so that the clamp rotating portion contacts the clamp fixing portion, there is no interference during stacking.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the pallet 1 is
Two pallet bodies 3 each having a block 2 protruding in a hollow shape on the back surface are rotatably connected by a hinge 4 so that the bottom surfaces of the blocks 2 provided on each of the pallet bodies 3 come into contact with each other, and A hook 6 provided on the back surface of the pallet body 3 is engaged with a clamp 6 provided on the back surface of the other pallet body 3.

The pallet body 3 is formed by using an aluminum wrought material having a thickness of 1.5 mm to 3 mm, and the block 2 is formed on the back surface by press molding.

The block 2 has a cavity 7 on the upper surface side of the pallet body 3 and is formed so as to bulge on the rear surface side. The block 2 is formed on the outer peripheral portion of the pallet body 3 at substantially equal intervals.
One is arranged, and one is arranged in the central portion. The block 2 has a horizontal or rectangular horizontal cross section, an opening wider than the bottom, and a wall surface having a slope.

As shown in FIG. 2, the blocks 2 arranged in the outer peripheral portion and the blocks 2 arranged in the central portion have different shapes, but the blocks 2 having the same shape can be formed. is there. Further, the number of blocks 2 is not limited to nine, and can be selected appropriately.

As shown in FIG. 2, the two pallet bodies 3 constructed as described above are arranged side by side so that the blocks 2 formed on the back surface of the pallet body 3 face in the same direction. It is rotatably connected.

The hinge 4, as shown in FIG.
It comprises a fixed portion 8 formed in a character shape, an arm portion 9 and a rolling portion 10 provided on the arm portion 9 which engage with each other. The rolling portions 10 are engaged with each other and rotated by a hinge shaft 11. It is formed by being pivotally attached as much as possible.

A hook 5 is fixed to an end of the back surface of one pallet body 3, and a clamp 6 engaging with the hook 5 is fixed to an end of the back surface of the other pallet body 3.

As shown in FIG. 4, the hook 5 is composed of a fixing portion 12 and an engaging portion 13, and is fixed to the pallet body 3 at the fixing portion 12. In addition, the clamp 6 has a fixed portion 14
And a clamp body 17 composed of a rotating portion 16 rotatably attached to the fixed portion 14 by a clamp shaft 15 and a support body 18 provided at an end of the rotating portion 16 so as to be rotatable. The handle 19 is supported, and the holder 20 is rotatably supported by the handle 19 and has a substantially U-shape.

The two pallet bodies 3 constructed as described above are folded in two by the hinges 4, the bottom faces 21 of the blocks 2 provided in each are brought into contact with each other, and the holder 20 of the clamp 6 is engaged with the hook 5. The hook 5 and the clamp 6 are engaged by hooking on the portion 13 and tilting the handle 19 to form the pallet 1.

In the above embodiment, the hinge 4 is replaced by 2
Although one piece is provided, one to three pieces can be provided depending on the structure of the pallet, and the pallet body 3 is provided with hinges 4 from the end of the fixed portion 8 of the hinge 4 to the end of the pallet body 3 as needed.
It is also possible to provide a notch 21 having a width of. Also, two hooks 5 and two clamps 6 are provided, but it is also possible to provide one to four hooks due to the structure of the pallet,
If necessary, it can be provided on both sides. Further, the hinge 4, the hook 5 and the clamp 6 are fixed to the pallet body 3 by joining means such as welding, welding or adhesion, or joining means such as bolts, screws or rivets.

In the above embodiment, the pallet body 3 is formed by using an aluminum wrought material. However, a steel plate, a metal plate such as an iron plate, a thermoplastic resin represented by polypropylene, a fiber reinforced thermoplastic resin, or It is also possible to mold a thermosetting resin typified by unsaturated polyester with a resin plate such as FRP reinforced with fibers or to perform injection molding with a resin.

Next, the stacked state of the developed pallets 1 will be described with reference to FIG. FIG. 5 shows the case where the height of the hinges 4 is higher than the distance between the stacked pallets 1, and the notch 21 is provided at the end of the pallet body 3, but when the distance between the pallets 1 is larger than the height of the hinges 4. It is not necessary to provide the cutout portion 21.

When the pallets 1 are stacked, the hinges 4 provided on the upper pallet 1 pass through the notches 21 formed on the lower pallet 1 and are inserted onto the hinges 4 of the lower pallet 1. It fits in shape. At this time, since the clamps are folded and the hooks are thin, they do not interfere with each other.

The pallets stacked as described above can be transported by a forklift.

[0021]

Since the present invention has the above-mentioned structure, it can be used as a flat pallet when two pallet bodies are folded, and after use, the clamp is removed and the upper pallet body and the lower pallet body are expanded. By doing so, it is possible to form a sheet. The above sheet-shaped pallet is
Since they can be stacked with a small gap, the space for storing and collecting pallets is small, and the cost required for them is also small. Further, since the cost for storage and recovery is low, the pallet can be used in the distribution process, which has a very excellent effect that it can greatly contribute to the rationalization of distribution.
