Description

[Technical Field]

[0001] The present invention relates to a resin pallet that can be connected in a planar direction. [Background technology]

[0002] Pallets (slatted flooring) are used in closets, cupboards, underfloor storage, entryways, verandas, storage sheds, bathrooms, washrooms, changing rooms, locker rooms, etc. Pallets (slatted flooring) are convenient for storage as they do not allow moisture to directly get into the stored items and do not get dirty with garbage. Pallets (slatted flooring) are made from resin, wood, metal, etc., but resin pallets are light and can be molded into various shapes, making them ideal for everyday items. Patent Document 1 proposes connecting multiple resin blocks with openings by inserting a connecting jig into them. Figure 2 of Patent Document 2 proposes connecting flat plates by providing recesses and protrusions on the sides of the flat plates and inserting the protrusions into the recesses.

[0009] The resin pallet of the present invention has a rectangular, flat top surface. The rectangular shape is preferably square or rectangular. The rectangular shape makes it easy to connect multiple pallets in a horizontal direction. The periphery of the top surface forms a side wall surface extending downward, and L-shaped joint portions are integrally molded on the outer sides of two adjacent sides of the top surface, allowing the side wall surfaces to be joined (connected) to the joint portions. This makes it possible to connect multiple pallets in a horizontal direction. Furthermore, the resin pallet of the present invention can be used alone or by connecting multiple pallets, and multiple pallets can be easily connected in a horizontal direction. In the above, flat includes a flat plate with no irregularities, and a matte-like irregularity that does not interfere with placing items on the top surface.

[0010] The resin pallet has multiple legs at the bottom, and it is preferable that the legs have hollow sections extending downward from the top surface. The presence of legs prevents moisture, dirt, mold, bacteria, etc. from below from coming into direct contact with the stored items, allowing for hygienic management and making floor cleaning easier. The multiple legs also allow for stable storage. The legs have hollow sections extending downward from the top surface, which makes them lighter and allows the legs to be inserted when stacked, reducing the volume. Reducing the volume is convenient when not in use and when transporting.

[0011] The cross section of the leg is preferably polygonal or circular. Polygons include any shape such as triangle, square, octagon, star, etc., while circular shapes include circle, ellipse, oval, etc. Such shapes make it convenient to insert the legs into each other. Furthermore, it is preferable that the legs have a tapered shape, with a thick upper part and a thin lower part, so that the legs of another resin pallet can be inserted from above into the hollow part and stacked. This reduces the volume, making it convenient when not in use and during transportation. The taper angle of the leg is preferably 2 to 15 degrees inward from a vertical line from the top surface, more preferably 4 to 10 degrees.

[0012] The resin pallet is preferably at least one selected from the group consisting of pallet (A) with a top surface length of L and width of W, pallet (B) with a top surface length of 1.5L and width of W, and pallet (C) with a top surface length of 1.5L and width of 1.5W. With these dimensions, pallets (A) to (C) can be used individually or can be conveniently connected in any combination to form a rectangle. For example, a small-sized pallet (A) with a top surface length of L = 20 cm and width of W = 20 cm, a medium-sized pallet (B) with a top surface length of 1.5L = 30 cm and width of W = 20 cm, and a large-sized pallet (C) with a top surface length of 1.5L = 30 cm and width of 1.5W = 30 cm can be used individually or can be increased in 10 cm increments from L = 20 cm and width = W = 20 cm.

[0013] For the resin pallet of the present invention, polyethylene, polypropylene, ABS resin, vinyl chloride resin, methacrylic resin, etc. can be used, but among these, polyolefin resins such as polyethylene and polypropylene are preferred.

[0014] The resin pallet of the present invention can be used in closets, cupboards, underfloor storage, entrance halls, verandas, storerooms, bathrooms, washrooms, changing rooms, locker rooms, etc., and is suitable for carrying clothes, bedding, home appliances, food, water, shoes, miscellaneous goods, plants, etc.

[0015] The following description will be given with reference to the drawings, in which the same reference numerals denote the same parts. Fig. 1A is a schematic front perspective view of a small-sized resin pallet 1 according to one embodiment of the present invention, and Fig. 1B is a schematic rear perspective view of Fig. 1A. This resin pallet 1 has a rectangular, flat top surface 2. The periphery of the top surface 2 is formed with side wall surfaces 3 extending downward. L-shaped joint portions 4a-4d are integrally molded on the outside of two adjacent sides of the top surface 2. By joining the side wall surfaces 3 to the joint portions 4a-4d, multiple pallets can be connected in a flat manner. There are a total of 16 legs 6 at the bottom of the resin pallet 1. The legs 6 have hollow portions 5 that extend downward from the top surface 2. The legs 6 of another pallet can be inserted into these hollow portions for stacking. The thickness of the top surface, side wall surfaces, legs, etc. of the resin pallet 1 is preferably 1 to 5 mm, more preferably 1.5 to 4 mm, and even more preferably 2 to 3 mm. The resin pallet 1 can be molded using an injection molding machine or the like.

[0016] Fig. 2A is a schematic front perspective view of a medium-sized resin pallet in one embodiment of the present invention, and Fig. 2B is a schematic rear perspective view of Fig. 2A. Fig. 3A is a schematic front perspective view of a large-sized resin pallet in one embodiment of the present invention, and Fig. 3B is a schematic rear perspective view of Fig. 3A. Although the sizes, number of joints, and number of legs and hollow parts differ, the basic shape is the same as Fig. 1.

[0017] Figure 4 is a schematic plan view of one or more connected resin pallets of the same or different sizes in one embodiment of the present invention. Although not shown in Figure 4, the small size shown in Figure 1 is 20 x 20 cm, so if this is included, the vertical length L can be increased in 10 cm increments from 20 cm, and the horizontal length W can be increased in 10 cm increments from 20 cm.

[0018] FIG. 5A is a schematic explanatory diagram of two stacked resin pallets according to one embodiment of the present invention, and FIG. 5B is a schematic side view of ten stacked pallets. As shown in FIG. 5A, by inserting the legs 6 of the upper pallet into the hollow portion 5 of the lower pallet, wasted space is eliminated, allowing for compact stacking. As shown in FIG. 5B, even when ten pallets are stacked, the height remains at 23 cm. This is convenient for storage and transportation when not in use. The pallet shown in FIGS. 5A-B is an example of a pallet with a height of 50 mm. When ten pallets are stacked, the total height is 50 mm x 10 pallets = 500 mm, but it fits into a 23 cm space, which is approximately 46% of the total, eliminating approximately 54% of wasted space when stored.

[0019] Fig. 6 is a schematic six-view diagram of a small-sized resin pallet in one embodiment of the present invention. Fig. 7 is a schematic six-view diagram of a medium-sized resin pallet in one embodiment of the present invention. Fig. 8 is a schematic six-view diagram of a large-sized resin pallet in one embodiment of the present invention. [Example]

[0020] The present invention will be described below using examples, but is not limited to these examples.

[0021] Example 1 Pallet 1 shown in Figures 1 and 6 was molded using polypropylene resin with an injection molding machine. The top surface was 200mm long and 200mm wide, the side wall height was 16mm, the overall height was 50mm, the width of the L-shaped joint was 30mm, the width of the slit pointing upward in the L-shaped joint was 2.5mm, the top surface of the hollow part of the leg was 20 x 20mm, the taper angle of the leg was tilted inward from the vertical by 6.5 degrees, and the wall thickness was 2.2mm. This resin pallet allows multiple pallets to be connected in a flat manner by joining the side wall surfaces at the joints, and is convenient because it does not take up much space when stacked for storage.

[0022] Example 2 The same procedure as in Example 1 was carried out, except for the use of Figures 2 and 7. This resin pallet also had side wall surfaces that could be joined at the joints, allowing multiple pallets to be connected in a flat manner, and was convenient because it did not take up much space when stacked for storage.
