Description

Description: BACKGROUND OF THE INVENTION [0001] The present invention relates to a pallet used for transportation and storage of articles, particularly plywood or particle board. [0002] [Prior Art] A known pallet is formed by an upper deck of corrugated cardboard and columns of paper tubes. Many Japanese Patent Laid-Open No. 61-81951 have been proposed. There is also a combination of a top deck and a post of a molded plastic product as in Japanese Utility Model Laid-Open No. 60-78726. Japanese Patent Application Laid-Open No. 51-93036 and the like have the pillars made of metal. [0003] [Problems to be solved by the invention] However, recently, there has arisen a problem of waste disposal and a need for a pallet manufacturer to save space as much as possible in terms of loading and storage efficiency in supplying it to a user. Regarding the problem of waste disposal, a very strict law has recently come out in Germany, in which product manufacturers are obliged to collect packaging materials. Therefore, in order to facilitate waste disposal, it is convenient to use a deck on the top, cardboard pallets made of paper and all the same material. However, JP-A-61-8
Corrugated cardboard pallets such as the 1951 are vulnerable to moisture, and because they are assembled by a pallet maker and then transported to the user for storage, the costs for freight and storage space are high. Actual Kaisho 60-7
As in 8726 and Japanese Patent Laid-Open No. 61-190442, since the columns are made of plastic or metal, they can be assembled prior to use by the user, so the freight and storage space are efficient, but there is a problem of waste disposal because it is a composite material. . In addition, since the pillar is a molded product, its storage space is also a problem. At the end of use, a pallet that can be easily disassembled and saved in a space-saving manner, which also reduces freight costs, has been awaited. [0004] [Means for Solving the Problems] Therefore, a pallet for which waste disposal is easy and which can be easily assembled and disassembled by the user has been awaited. The present invention has been invented to meet the above demands. The feature is that the pillar is plate-shaped, and the pillar projection 31 is inserted into the upper deck hole 11 formed in the upper deck 1 and the retainer groove 22 of the retainer 2, which is also adhered to the lower surface thereof, and the pillar projection 31 is slid. By engaging the strut groove 32 with the strut groove engaging hole 24, the strut body 3 and the upper deck 1 can be detached. As for the material, the upper deck 1, the lower deck 10, and the support columns are the same or similar materials. For example, particle board or plywood is good. [0005] [Operation] The combined structure as described above can be assembled and disassembled with one touch, and the assembled finished product has a high withstand pressure from above and a high strength against sideways shaking.
In addition, as it is easy to assemble and disassemble, it is possible to save space during storage. [0006] [Embodiment] An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an assembled and completed pallet of the present invention. However, only the uppermost part of the pillar body is displayed. Fig. 2 is a perspective view showing a part of the elements for assembling the assembled pallet shown in Fig. 1.
That is, the upper deck 1, the lower deck 10 (not shown), and the retainer adhered to the lower surface of the upper deck 1, that is, the retainer 2 and the pillar main body 3 which is inserted into and slidably engaged with the retainer 2 are illustrated. There is. These four parts are made of the same material or similar materials. Plywood or particle board is good material. It is a plate. The column has a column body 3 and column end faces 33 that support the loads of the upper deck 1 and the lower deck 10 on the upper and lower sides. A column protrusion 31 is provided on the upper portion of the column end face 33 in the horizontal direction. A strut groove 32 is provided between the strut end face 33 and the strut protrusion 31.
Are provided horizontally. On the other hand, the retainer 2 is a component that is adhesively fixed to the upper deck 1 and the lower deck 10. The structure is provided with a retainer groove 22 having a length equal to or greater than the entire length and width of the column protrusion 31. A strut groove engaging hole 24 is provided adjacent to the retainer groove 22.
The strut groove engaging hole 24 is equal to or larger than the total length of the neck portion formed by the two strut grooves 32. Both ends of the strut groove engaging hole 24 form a strut protrusion support piece 21 that receives the load of the strut protrusion 31. On the other hand, the upper deck 1 is provided with upper pillar holes 31 for preventing the movement of the pillar protrusions 31 and the pillar protrusions 31 when the pillar protrusions 31 slide into the pillar groove engaging holes 24. Adhesive 23 is appropriately applied to the surface of the retainer 2 and the upper surface deck hole 11 is aligned with the retainer groove 22 and the post groove engaging hole 24 to be fixed by adhesion. In this embodiment, the upper deck hole 1
Although 1 is a quadrangle that can be easily processed, its shape is not limited to a quadrangle, and any shape is possible as long as the support protrusions 21 for the support pillars are secured. The width of the strut groove 32 is equal to or larger than the thickness of the retainer 2. The adhesive 23 may be fixed with nails. Retainer groove 22
Need not be rectangular as long as the pillar protrusion 31 can be easily inserted. The upper deck 1, the lower deck 10, the retainer 2, and the pillar body 3 use, for example, a 9 mm particle board, and the pillar body 3 does not necessarily have to have the same thickness, but the retainer groove 22 is equal to the pillar material thickness. Or
It only has to be wider than that. As for the processing method of these four parts, if the thickness is about 9 mm, it is possible to punch using a combination of a steel rule die and a hydraulic press machine. Alternatively, it can be made using a drilling machine and an automatic grooving machine. It can also be manufactured with a carbon dioxide laser cutting machine. Material thickness is 9
If it is thicker than mm, punching becomes difficult. For example, 18
When the thickness of millimeter is required, it is also possible to stack two 9 millimeters. For 9mm thickness, 3mm material is 3
It is also possible to stack sheets. If the material has a thickness of 3 mm, it can be produced at high speed with an automatic punching machine for paper making. As shown in FIG. 2, these pillar bodies 3 are inserted from below in alignment with the pillar projections 31 and the retainer grooves 22 provided in the retainer 2. When the column end surface 33 comes to the position of the lower surface of the retainer 2, the column body 3 slides. The arrow in FIG. 2 indicates the moving direction. Then, the pillar protrusion 31 is slid and fixed on the pillar protrusion supporting piece 21. By sliding in the opposite direction, the pillar protrusion 31 can be detached from the retainer groove 22. Although the shape of the lower deck 10 is the same as that of the upper deck 1 in the embodiment, it is not limited thereto. That is, the actual exploitation 49
It is also possible in the case where there is no lower deck 10 itself as in No. -32074. At that time, the lower pillar protrusion 3 to be grounded
1, the support groove 32 is unnecessary. Also, instead of a single plate, there may be a case where it is in the form of an elongated plate with three rows as in Japanese Utility Model Laid-Open No. 58-130931. It is also possible that the column protrusion 31 projects slightly from the upper deck hole 11. In that case, it is possible to prevent the luggage placed on the upper deck from slipping sideways. FIG. 3 is a plan view of the retainer 2. When sliding, the strut groove 32 hits the hole slope 26 and a strong resistance is met, and it is possible to prevent the strut from dropping off during transportation. The hole slope 26 can be provided on the outer periphery of the upper deck hole 11. Although it is inclined in this embodiment, it is also possible to form a protrusion. The retainer 2 has a rectangular shape, but is not limited thereto. That is, it may have the same size as the upper deck 1. Further, by constructing an elongated member having three horizontal holes in FIG. 1 as one unit and adhering it to the back surface of the upper deck 1, the strength of the upper deck 1 in the lateral direction can be doubled. The retainer 2 need not be pre-bonded to the upper deck 1 before the strut body 3 is inserted into the retainer 2. That is, at the time of initial assembly, it is also possible to engage all of the support body 3 and the retainer 2 and then apply an adhesive to fix and mount the upper deck 1. [0007] [Advantages of the Invention] (A) In the present invention, since the materials of all parts of the pallet are made of the same or similar wood materials, they can be easily disposed of at the time of disposal. (B) In the present invention, the pallet manufacturer does not assemble and complete the product, but assembles it by the user himself without carrying it in. In particular, the user may assemble it as needed. Even when compared with the case where a paper tube is used for the supporting column, the supporting column of the present invention has a plate shape, and thus saves space. (C) Since the present invention is an assembling method, it can be disassembled as needed to save space and be reused. If the pallet is damaged, it can be disassembled so that only the damaged parts can be replaced. (D) Since the present invention is slippery in the case of a particle board or a plywood, the pillar protrusions 31 are provided on the upper deck hole 11
By making it jump out a little, it will be non-slip.
It can also be tapped when disassembling.
