DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet which is lifted by a claw of a forklift inserted and configured to carry a load placed thereon.

[0002]

2. Description of the Related Art Conventionally, a pallet which is lifted up by a claw of an inserted forklift and is configured to carry a loaded luggage, for example, as shown in FIGS. On the upper surface of a plurality of wooden beams 1 having a rectangular cross section arranged in parallel, a wooden upper plate 3 called a plurality of deck boards is stretched, and a water level plane UH on which the load C is placed is formed. There is known a forklift in which a pair of claws insertion portions I are formed in a portion surrounded by the girders 1 and 1 and the upper plate 3. FIG. 17 shows a structure in which a wooden lower plate 2 is stretched on the lower surface of the girder 1.

However, the pallets have the following disadvantages. (A) It is not possible to unload only the luggage C with a forklift. Luggage C placed on the horizontal plane UH of the pallet
Is to insert the claw of the forklift between the lower surface of the load C and the upper horizontal plane UH of the pallet, and try to lower the load with the forklift. In general, there is no gap in which the claw can be inserted, and only the load C is lowered. There is a drawback that you can not do. Therefore, there is no other way than to unload the load C by another means, and until all the load C is unloaded and there is no load on the pallet, even if the pallet alone is to be moved and collected, it cannot be moved.

For example, when a plaster board used as a wall material is transported for a very short distance, it can be directly loaded and unloaded with a forklift. However, in the case of long-distance transportation that requires a truck or the like, it is generally placed on a pallet to prevent breakage and the like. In this case as well, when the forklift claw is inserted between the lower surface of the plaster board and the upper surface of the pallet at the transport destination and the forklift is attempted to be lowered, there is no gap where the claw can be inserted, and only the plaster board is lowered. Can not do. Therefore, the only way to remove the plaster board is by another means, and until all the plaster boards have been dropped and there are no plaster boards on the pallet, the pallet alone cannot be recovered. Thus, the pallets remain at the transport destination, take up space, and must come again at a later date to retrieve the pallets.

[0005] (a) It is difficult or impossible to strap the loaded luggage or remove the strap hung on the luggage. The general baggage C having a flat lower surface and little gap between the pallet and the pallet cannot pass through the band between the horizontal surface UH of the pallet and the baggage C, so that it is difficult or impossible to band the baggage C on the baggage C. It is. Similarly, a band hung only on luggage can be cut with scissors or the like, but it is difficult or impossible to pull out and remove it. Especially metal bands,
If the cutting is continued, the sharp cutting portion protrudes and is dangerous for the operation, so it is necessary to remove it. However, if the user pulls it with bare hands to remove it, it may be injured, which is rather dangerous.

[0006] There are not only wooden pallets but also plastic and metal pallets, but all have the above-mentioned drawbacks because they have a flat upper surface.

[0007]

An object of the present invention is to solve the two drawbacks of the above-mentioned conventional pallet, and to use a forklift to unload only luggage. Are to provide an easy pallet.

[0008]

In order to achieve the above object, a pallet according to the present invention has an upper horizontal surface (UH) on which a load (C) can be placed, and the upper horizontal surface (UH). A pallet, which is formed below the pallet, is formed with a claw insertion portion (I) into which a claw (F) of a forklift that rises and falls is horizontally inserted from a side surface, and is lifted or lowered by lifting and lowering the claw (F) of the forklift; A groove (G) is formed in the upper horizontal surface (UH) so that the claw (F) of the forklift can be inserted horizontally from the side and is parallel to the insertion direction of the insertion portion (I). Is deeper than the claw (F) of the forklift, and the groove width is larger than the width of the claw (F).
The claw (F) at a position lower than the position of the upper horizontal plane (UH) inserted horizontally from the side surface can be raised to a position higher than the position of the upper horizontal plane (UH), and the loaded luggage (C) Only the upper horizontal surface (UH) can be separated and lifted.

According to a second aspect of the present invention, in addition to the configuration of the first aspect, a partition (HP) is provided above the claw insertion portion (I).
The groove (G) is arranged at a distance.

According to a third aspect of the present invention, in addition to the configuration of the first aspect, the claw insertion portion (I) and the groove (G) are arranged adjacent to each other with a partition wall therebetween, and a part of the partition wall is provided. The opening (O) through which the claw (F) of the forklift can freely penetrate is formed.

The symbols in parentheses above correspond to the symbols described in the drawings and the embodiments of the invention described later.

According to the first aspect of the invention, the pawl of the forklift inserted into the groove can freely rise from a position lower than the upper horizontal plane to a higher position beyond the upper horizontal plane, so that it can be mounted on the pallet. Even if the loaded luggage has a flat lower surface, it is easy to insert a claw of a forklift thereunder. Further, only the luggage can be lifted separately from the pallet by lifting and lowering the claw. Thus, during transportation,
Lift and carry only the luggage with a forklift at the destination,
The pallet can be taken down, so that the pallet can be brought back without the need to retrieve the pallet later. As described above, by replacing the claw of the forklift with the claw insertion portion and the groove, not only the transportation of the pallet on which the load is placed, but also the lowering of only the load can be performed by the same forklift. Excellent workability and extremely convenient.

In addition, not only a nail but also a band can be inserted and passed through the groove.
Even for a luggage having a flat lower surface, it is possible to easily strap the luggage only by passing the band through the groove. Further, as described above, the band hung only on the luggage is not restrained by the luggage and the pallet, and can be easily pulled out and removed through the groove when cut. In particular, when the metal band remains cut, a sharp cut portion protrudes, and a metal band that is dangerous for work can be easily removed without cutting force by cutting and pulling.

According to the second aspect, in addition to the functions and effects of the first aspect, if the groove is disposed immediately above the claw insertion portion with a partition wall therebetween, the claw insertion portion and Since the replacement of the claw with the groove is performed only by moving the forklift forward and backward and slightly moving the claw, the workability is excellent.

According to the third aspect, in addition to the operation and effect of the first aspect, there is no need to replace the claw between the claw insertion portion and the groove, so that the forklift does not move forward and backward.
Therefore, the pallet on which the load is placed can be transported and only the load can be loaded and unloaded by using the same forklift by slightly moving the pawl left, right, up and down, which is more convenient.

[0016]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a pallet according to a first embodiment of the present invention, FIG. 2 is a cross-sectional view showing a state where luggage is placed on the pallet of FIG. 1, and FIG. 3 is a forklift of FIG.
