Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a pallet for transporting articles. In particular, the invention relates to a pallet for transporting articles suitable for being manufactured by molding plastic. The pallet for carrying articles according to the present invention is suitable for carrying lightweight items, but is not limited to its use.

[0002]

BACKGROUND OF THE INVENTION It has already become commonplace to manufacture pallets for transporting goods from plastic materials. This pallet is provided with a pallet plate having a substantially flat upper surface on which an article is placed so that it can be handled by a forklift or the like, and legs provided below the pallet plate are provided. The pallet plate and the legs are integrally formed by molding a plastic material.

[0003]

A conventional pallet for carrying articles, which is made of a plastic material, has a pallet plate and legs that are integrally formed. Therefore, it is necessary to provide a pallet having all required dimensions. . Further, since the legs are projected from the pallet plate, there is a problem that a space is required for transportation and storage of the pallet.

The present invention solves the above-mentioned problems in conventional pallets, and provides a pallet for transporting articles which allows pallets of various sizes to be assembled on-site as needed and which is convenient for transportation and storage. Is an issue.

[0005]

In order to solve the above problems, in the present invention, the pallet plate and the legs are configured as separate parts. The pallet plate has a flat shape with cutouts formed in at least four corners, and the legs are attached to each of the cutouts at the four corners of the pallet plate by a fitting. The legs have a hollow shape that opens upward and projects downward, and it is possible to stack a plurality of pallets vertically while the legs are attached to the pallet plate. A feature of the present invention is that the two leg portions arranged along the same edge of the pallet plate are integrally connected.

[0006]

[Effects] In the pallet of the present invention, since the pallet plate and the legs are configured as separate parts before use, the space can be saved during transportation and storage. In use, it can be used simply by attaching the leg part to a predetermined position of the pallet plate. Furthermore, by preparing pallet plates of various sizes, it is possible to obtain a pallet having a desired size by sharing the legs. Further, since the leg portions are hollow so as to open upward and project downward, it is possible to stack the pallets vertically while the leg portions are attached to the pallet plate. The configuration in which the two legs are integrally connected in the present invention brings about the effect of reducing the number of parts, facilitating the handling, and simplifying the manufacturing.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, a pallet 1 as a reference example of the present invention has a pallet plate 2 having a flat shape. The pallet board 2 is
It has square cutouts 2a at the four corners.
A square opening 2b is formed in the center of the pallet plate 2. The legs 3 are attached to the cutouts 2a at the four corners of the pallet plate, and the openings 2b at the center are provided.
A leg 4 is attached to the.

FIG. 2 shows details of the leg portions 3 attached to the four corners of the pallet plate 2. The leg portion 3 has a main body portion 3a which is tapered downward in a quadrangular pyramid shape, and a flange 3b is formed around the upper edge portion of the main body portion 3a. As shown in FIG. 2b, the legs 3 are hollow with an upward opening and the tapered bottom 3c is closed. The peripheral flange 3b is wide on two adjacent sides and narrow on the other two sides. The vicinity of the center of each wide flange portion is cut out as shown in FIG. 2c, and the flange 3 is formed below the cutout portion.
Clamping tabs 3d are integrally formed with a space below b. The distance between the flange 3b and the tab 3d has a dimension corresponding to the thickness of the pallet plate 2. A cylindrical boss 3e is formed on the lower surface of the holding tab 3d so as to project downward. A hole 3f for a fixture is formed through the boss 3e of the tab 3d.

A cross-shaped pedestal 3g is formed on the bottom of the leg portion 3. The pedestal 3g is formed such that when the leg portions 3 having the same shape are vertically stacked, the bottom surface of the upper leg portion rests on the upper surface of the pedestal 3g of the lower leg portion. FIG. 3 shows the leg portion 4 attached to the central opening 2b of the pallet plate 2. The leg portion 4 has a main body portion 4a which is open upward and has a closed bottom portion, and a flange 4b having a uniform width is formed around the upper edge portion of the main body portion 4a. The main body portion 4a is tapered downward, and a step portion 4c is formed in the middle portion of the side surface. On each side of the flange 4b, a cylindrical boss 3d is formed on the lower surface of the central portion.
Is formed, and a hole 3e for a fixture is formed through the boss 3d.
Are formed.

4 and 5 show a state in which the leg portions 3 and 4 are attached to the pallet plate 2. The leg portion 3 is arranged such that the edge portion of the cutout portion 2a at the corner portion of the pallet plate 2 is sandwiched by the flange 3b and the sandwiching tab 3d. The pallet plate 2 has a hole 3f penetrating the flange 3b of the leg portion 3 and the pinching tab 3d.
The holes for the fixtures are formed at the positions overlapping with each other. The legs 3 are positioned so that these holes overlap, and the fixtures 5 are inserted.

FIG. 6 shows details of the fixture 5. Fixture 5
Comprises a lock pin 5a shown in FIG. 6a and a hollow rivet 5b shown in FIG. 6b, both of which pins 5a and rivets 5b are made of a plastic material. The rivet 5b has a hollow tubular portion 5c, and the tubular portion 5c
A dish-shaped head 5d is formed on the upper end of the. Tubular part 5c
In the lower part of the shaft, axial slits 5e are formed at four locations facing each other in the radial direction, and claws 5f protruding outward in the radial direction are formed at the lower end. The lock pin 5a shown in FIG. 6a has a hollow rod-shaped shaft portion 5g, and a disk-shaped head portion 5h is formed at the upper end of the shaft portion 5g.
A recess for receiving the head 5h of the lock pin 5a is formed on the upper surface of the head 5d of the rivet 5b.

When using the fixture 5 having such a structure, first, the rivet 5b is inserted into the holes formed in the pallet plate 2 and the leg portion 3. At this time, since the slit 5e is formed at the tip of the rivet 5b, the rivet 5b is radially reduced and inserted into the hole. Next, the lock pin 5a is inserted into the tubular portion 5c of the rivet 5b. Lock pin 5a
Since the tip of the rivet 5b pushes the tip of the tubular portion 5c of the rivet 5b in the radial direction, the claw 5f engages with the lower surface of the boss 3e of the leg 3 to fix the leg 3 to the pallet plate 2. FIG. 5a shows details of the attachment state of the leg portion 3.

The leg 4 is, as shown in FIGS. 4 and 5b,
It is attached to the lower surface of the pallet board 2. For installation,
The fixture 5 shown in FIG. 6 is used. The attachment method is the same as the attachment of the leg portion 3. 7 and 8 show an embodiment of the present invention. In the embodiments of the present invention, portions corresponding to those of the structure shown in FIGS. 1 to 6 are designated by the same reference numerals, and detailed description thereof will be omitted. In this embodiment, a pair of leg portions 3 arranged along one side of the pallet plate 2 are integrally connected by a connecting member 6. This connecting member 6 is
In addition to the action of connecting the legs 3 to each other, it also acts to increase the rigidity of the pallet itself.

FIG. 9 shows still another reference example. In this reference example, the pallet plate 12 is not provided with a notch, and no opening is formed in the central portion. The leg portions 13 attached to the four corners of the pallet plate 12 and the leg portions 14 attached to the central portion are attached to the lower surface of the pallet plate 12 by being attached thereto. A fixture 5 as shown in FIG. 6 is used for attachment.
