Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pallet that prevents cargo on the pallet from collapsing.

[Prior Art] Traditionally, wooden or metal pallets have been widely used for storing and transporting cargo, but these pallets have problems in terms of water resistance, corrosion resistance, and hygiene, and these properties have recently been improved. Synthetic resin pallets have been used since they have excellent properties.

The above-mentioned synthetic resin pallets are manufactured by blow molding, injection molding, etc., but the pallet and the load are sometimes fixed with bands or the like to prevent the load from collapsing.

In this case, in most cases the band is passed through the fork insertion port and tightened, but this method has the disadvantage that the band must be passed through the fork insertion port each time a load is placed, which is time-consuming.

For this reason, in injection molded pallets, a method is used in which a hook is attached to a rubber band and the hook is hooked onto the girder part of the pallet to easily secure the load.

However, in the case of a pallet made by blow molding, in order to hang a hook, it is necessary to make a hole in the side or attach a hook part. In the former case,
There are problems in that it deforms when hooked, and water tends to get inside, which is not sanitary. Furthermore, in the latter case, there are problems with the strength of the mounting portion and the high cost of manufacturing the parts.

[Object of the invention] An object of the present invention is to provide a pallet formed by blow molding which eliminates the above-mentioned drawbacks of the prior art.

[Means for solving the problem] The present invention consists of an outer plate, an inner plate, a side plate around the outer periphery of the double-sided plate, and a required number of reinforcing plates integrally connected across the outer plate and the inner plate. , the inner surface plate has a required number of convex portions having a flat upper surface and parallel to the inner surface plate at the corners, the outer periphery, and the center, and at least one pair of convex portions are formed on the convex portions located at opposite positions among the convex portions. It has a hook hooking recess, and the recess has a first recessed part in which the ridgeline part where the flat surface and the outer surface of the convex part are recessed toward the outer surface plate, and a first recessed part that is in contact with the first recessed part and located on the center side of the convex part. and a rectangular hollow plate-like body consisting of a second recessed part having a larger recess than the first recessed part, and two of the hollow plate-like members are arranged so that the hook hooking recessed parts face each other. This pallet is characterized by its surfaces being connected and fixed together by heat welding.

[Example] Next, the present invention will be explained based on examples.

1 and 2 are diagrams showing an embodiment of the present invention, and FIG. 1 is a plan view of a pallet;
FIG. 2 is a sectional view of the main part taken along the line -- in FIG. 1. The pallet 1 is composed of two hollow plate-like bodies 2, 2. That is, the hollow plate-like body 2 has an outer plate 3 on which a load is placed, an inner plate 4 having nine protrusions 5 projecting thereon,
It consists of an internal reinforcing plate 9 in the longitudinal direction, and has two pairs of hook hooking recesses 7 in the protrusion 5 located approximately at the center of the side of the protrusion having an outer surface 6. The recess 7 is
A first recessed portion 11 in which the ridgeline portion where the flat surface and the outer surface of the convex portion are in contact is recessed toward the outer surface plate, and the first recessed portion 11 is located in contact with the first recessed portion toward the center of the convex portion;
It consists of a second depressed portion 12 having an even larger depression. The pallet 1 is made up of hollow plates 2, 2.
This is a double-sided pallet in which the convex portions 5, 5 of the pallet are opposed to each other, and their respective flat surfaces are connected and integrated by heat welding, and the convex portions 5, 5 serve as supports 8.

The required number of reinforcing plates 9 installed inside the hollow plate-like body 2 are provided at key points, and the outer plate 3 constituting the hollow plate-like body 2
and the double-sided plate 4 are integrally connected. This reinforcing plate 9 is made by welding a part of the parison with the sliding part provided in the mold protruding when air blowing a synthetic resin parison to form the hollow plate body 2.
Thereafter, by returning the sliding portion to the inner surface of the mold and blowing with air, it can be integrally molded with the hollow plate.

Similarly, the hook hook recess 7 can also be formed at the same time.

Further, FIG. 3 is a sectional view of a main part of a pallet showing another embodiment of the present invention. In this case, the reinforcing plate 10
is formed by compression from the direction of the inner surface plate 4.

Examples of how the pallet 1 thus formed is used are shown in FIGS. 4 and 5. FIG. 4 is a front view showing an example of a usage mode, and FIG. 5 is a sectional view of a main part of FIG. 4, explaining hooking. The load 21 is placed on the outer plate 3, and the band 2 is attached to prevent the load from collapsing.
Multiply by 2. For band hanging, the hook 23 of the band 22 is hooked onto the hook hook recess 7 to fix the load on the pallet.

The required number of hook hooking recesses 7 may be provided in pairs at appropriate positions facing each other.
As shown in FIG. 1, two pairs of hook recesses 7 may be provided approximately at the center of each side surface of the pallet.

Further, as shown in FIG. 5, the hook hooking portion of the hook hooking recess 7 supports the bending stress from the hook 23 by both the outer surface 6 and the recess surface 13 (shown in FIG. 2). Therefore, the stress is dispersed, and the hook hook recess 7 has a structure with excellent strength.

[Effects of the invention] (1) According to the invention, the hook of the band that secures the load can be easily hung in the hook hook recess provided on the outer surface of the pallet support, so there is no need to worry about the load collapsing. There is no.

(2) According to the present invention, the hook hook recess is easily formed in one piece during molding, so there is no need to worry about post-processing, and costs can be reduced. It is extremely hygienic as it does not contain dirt.

(3) According to the present invention, there is no need to pass a fixing band through the fork insertion port in order to fix the loaded object.
Another advantage is that work efficiency is improved.

(4) The hook hook recess according to the present invention has excellent bending stress without the need for special measures such as reinforcing ribs.
