[Problem to be solved by the invention]

In the above-mentioned pallets with constant vertical and horizontal dimensions, it is necessary to prepare many types of pallets with different vertical and horizontal dimensions in advance, and if pallets that differ in size from the cargo are used, for example, the pallet When the size of the pallet is larger than the size of the cargo, there is a waste of space, and when the size of the pallet is smaller than the size of the cargo, there are problems such as instability during transportation. In addition, in the case of the above-mentioned pallet whose size is variable, the extended pallet, divided molded product, multiple divided pieces, two or more pallet constituent members, etc. disclosed in each publication have constant vertical and horizontal dimensions. Because things are combined, the size that changes in the vertical and horizontal dimensions is an integral multiple of the extended pallet, divided molded product, divided piece, component member, etc. For example, if the vertical and horizontal dimensions are changed arbitrarily. It is not possible to assemble pallets, and in this case, extended pallets with different vertical and horizontal dimensions,
There was a problem in that a pallet of a desired size could not be assembled unless a wide variety of divided molded products, divided pieces, constituent members, etc. were prepared. Furthermore, when assembling pallets with arbitrarily changed vertical and horizontal dimensions, it is troublesome to connect them, and there is also the problem that much labor and time are required for assembly and disassembly. The present invention has been made to solve the above problems.

[Means to solve the problem]

In order to achieve the above object, the present invention makes it possible to assemble a pallet of planar quadrilaterals on which cargo is loaded, using blocks of a plurality of planar quadrilaterals, and blocks with the same vertical and horizontal dimension ratios and blocks with different horizontal and vertical dimension ratios. In the assembly type pallet, each of the plurality of blocks has the same thickness, has fork insertion holes into which forks of a forklift are inserted in the front-rear direction and left-right direction, and has fork insertion holes that engage with the outer periphery of the quadrilateral. Protrusions and engaging recesses are provided, connecting holes are formed in the outer peripheral corners, and cross connecting pieces or flat connecting pieces that can be fitted into and removed from the connecting holes of opposing blocks are provided. Assemble multiple types of pallets with different vertical and horizontal dimensions by connecting multiple blocks with the same dimensions, or multiple blocks with different vertical and horizontal dimensions, and connecting the vertical or horizontal parts of each with the same length. It is characterized by the fact that it is possible.

[Effect]

With the above configuration, the present invention can easily assemble and disassemble a pallet of a desired size by combining a plurality of blocks with different vertical and horizontal dimensions, and can be assembled appropriately depending on the size of the cargo. Pallets of various sizes can be assembled and used. Moreover, by preparing about three types of blocks with different vertical and horizontal dimensions, it is possible to arbitrarily assemble many types of pallets.

【Example】

An embodiment of the present invention will be described below with reference to the drawings. In Figs. 1 to 3, reference numeral 1 designates one block that composes the pallet. This block 1 is integrally molded from reinforced synthetic resin, has a constant thickness 2, and The fork of the fork wrist (not shown) in the thickness 2 is in the front and back direction,
Front and rear fork insertion holes 3 and left and right fork insertion holes 4, which can be inserted from either the left or right direction, are provided. Further, the block 1 has a quadrilateral planar shape, and a pair of engagement protrusions 5 and an engagement recess 6 are provided on the outer periphery of the block 1.
are formed in a shape that allows them to engage and disengage from each other and to exhibit sufficient strength when engaged. Furthermore, connection holes 7 are formed at the four corners of the block 1, passing through them in the vertical direction. When the four blocks 1 are engaged as shown in FIG. 5, a cross connecting piece 8 shown in FIG. , two blocks 1 as shown in FIG.
When the blocks 1 are engaged in a planar manner, the planar connecting pieces 9 shown in FIG. 6 are fitted, and as shown in FIG. The corner pieces 10 shown are fitted. Then, a cross connection piece 8, a plane connection piece 9,
The corner pieces 10 are wedge-shaped so that when they are fitted into the connecting holes 7, they cannot be easily pulled out in the vertical direction. The block 1 is, for example, shown in FIGS.
As shown in Figure 2, the length and width are 40 x 40 cm, A is 40 x 30 cm, B is 40 x 30 cm, and 30 x 30 cm is C. Prepare a 120 x 120 screen as shown in Figure 13.
It is possible to arbitrarily assemble pallets from cm to 90 x 90 cm. During this assembly, three vertical or horizontal rows are engaged in a rectangular shape, and then three sets of rows are engaged with each other to assemble a quadrilateral pallet. A planar connecting piece 9 is fitted to the connecting portion, and a corner piece 10 is fitted to the corner portion. By engaging the blocks 1 and connecting the connecting pieces 8 to 10 in this manner, ten types of pallets having different vertical and horizontal dimensions as shown in FIG. 13 can be assembled. Furthermore, by varying the engagement lengths of the blocks and combining them, it is possible to assemble pallets suitable for loads of various sizes. In a prefabricated pallet with such a configuration,
Depending on the size of the cargo to be loaded on the pallet, for example, the vertical and horizontal dimensions may be 120 x 120 as shown in Figure 13.
Ten types are easily assembled, from cm-2 to 90 x 90 cm, and the fork of the forklift can be inserted either vertically or horizontally to transport them. In this way, if the size of the cargo and the size of the pallet match, not only can stable transportation be possible, but also it is possible to load the cargo into a container, for example, or to place loaded pallets side by side in a warehouse or material storage area. In this case, there is no wasted space between items. Furthermore, the pallets are firmly engaged by the engaging protrusions 5 and the engaging recesses 6, and are also connected by the cross connecting pieces 8 and the planar connecting pieces 9, so they have sufficient strength. Since the corner pieces 10 are fitted, the pallet as a whole is formed flat and is easy to use.

【Effect of the invention】

As explained above, according to the assembly type pallet of the present invention, a plurality of blocks can be connected by engaging projections and engaging recesses, connecting holes and removable cross connecting pieces, planar connecting pieces, etc. , pallets with different vertical and horizontal dimensions can be assembled by being connected to each other, so pallets of the desired size that matches the size of the cargo can be easily assembled and used in a short time, and are stable. This allows for easy transportation, and there is no waste of space for loading cargo. Further, it is easy to disassemble and there is no problem in terms of strength. Moreover, the assembled pallets are
It is possible to transport by inserting a fork from either the left or right direction, and by preparing several types of blocks with different vertical and horizontal dimensions, a pallet of the desired size can be assembled, so it is possible to assemble a large number of pallets of a certain size in advance. Compared to the case where different types of pallets are prepared, the amount of materials used can be significantly reduced, and no space is required to store multiple types of pallets.
