Description

Description: TECHNICAL FIELD The present invention relates to a pallet on which a load (various objects) is placed and transported by a forklift, a hand lifter, or the like. More particularly, the present invention relates to a pallet in which a fork such as a forklift can be easily inserted and the strength of the inserted portion is high.

[Prior Art] A pallet carried by a forklift or a hand lifter has a configuration in which legs are provided on the lower surface of a rectangular deck board. This pallet includes a double-sided type in which two deck boards are connected by legs, a single-sided type in which legs are provided on only one side of the deck board, and a skid type.

This deck board is provided with a frame in the shape of a girder formed integrally with synthetic resin, and a plate is often provided in the frame of the frame (for example, Japanese Patent Publication No. 60-55).
No. 374).

[Problems to be Solved by the Invention] The conventional deck board of a pallet has a uniform thickness from the center to the periphery, and the tip of the fork easily hits the side end face of the deck board when the fork is inserted. There was a problem that it was difficult to insert a fork.

Further, there is another problem that the side end surface of the deck board is easily damaged by the contact of the fork tip.

Means for Solving the Problems A pallet according to the present invention includes a substantially rectangular deck board on which a load is loaded on an upper surface, and a plurality of legs protruding from a lower surface of the deck board. The board has a frame extending in the vertical and horizontal directions with respect to the side direction of the deck board, and the frame relates to a pallet which is a cross-shaped combination of plate-like materials whose plate surface is orthogonal to the deck board loading surface.

The pallet according to claim 1, wherein the lower surface of the frame is covered with a plate at the edge of the deck board, and the plate is inclined so as to be higher toward the tip of the edge, and the plate is below the plate. The level portion is provided with an opening for draining water.

The pallet according to claim 2 is characterized in that, in the pallet according to claim 1, a first rib for reinforcing the plate extends toward a tip of the peripheral portion on an upper surface of the plate. It is.

The pallet according to claim 3 is the pallet according to claim 2, wherein a second rib for reinforcing the plate extends in a direction parallel to a side of the deck board on an upper surface of the plate, and the second rib is The base end in the extending direction is connected to a frame or a first rib, and the distal end in the extending direction is separated from the frame or the first rib.

[Operation] In the pallet according to the first aspect, the fork can be easily inserted because the lower surface of the edge of the deck board is inclined. Since the lower surface portion is formed of a plate, the fork that hits the lower surface portion is smoothly guided and inserted in the depth direction. Since this plate is provided with a drain opening, water and dust hardly collect.

In the pallets according to the second and third aspects, the plate is reinforced with ribs, and has extremely high strength. Therefore, even if the fork repeatedly hits, no damage occurs and the durability becomes excellent.

In particular, in claim 3, since a gap is provided between the tip end side of the second rib and the frame or the first rib, water or dust flows toward the lower direction of the plate and the opening is formed. Will be surely discharged.

Embodiment An embodiment will be described below with reference to the drawings.

FIG. 1 is a perspective view of an essential part of a pallet according to an embodiment of the present invention, FIG. 2 is a sectional view taken along the line II-II of FIG. 1, and FIG. FIG. 4 is a sectional view taken along the line IV-IV in FIG.

The pallet 10 according to this embodiment is of a double-sided deck type made of synthetic resin, and has a pair of rectangular board-like deck boards.
12 and 14 are connected via legs 16 and deck board 1
A gap for inserting a fork such as a forklift (not shown) is formed between two and fourteen.

Since the deck boards 12 and 14 have a vertically symmetric configuration, the configuration of the deck board 12 will be described first.

The deck board 12 has a frame 18. The frame 18 extends in the vertical and horizontal directions with respect to the side direction of the deck board 12. The frame 18 is a plate-like material whose plate surface is orthogonal to the deck board loading surface P (see FIG. 2).
18a is formed in a cross-girder shape. In the present embodiment, the plane members 20 and 22 are provided in the grid portion of the frame 18.
The flat material 20 is provided along the loading surface P (upper surface) of the deck board 12, and the flat material 22 is provided along the lower surface of the deck board 12. Openings 20a and 22a are provided in the plane members 20 and 22, respectively.

At the periphery of the deck board 12, the lower surface of the frame 18 is covered with a plate 24. The plate 24 is inclined so as to be higher at the tip of the edge. At the periphery, the frame 18 is also inclined so that the lower surface of the frame 18 follows the plate 24, so that the front end of the periphery is higher.

An opening 26 for draining water is formed in a lower level portion of the plate 24. In order to reinforce the plate 24, a first rib 28 is provided on the upper surface of the plate 24 so as to extend toward the tip of the edge of the deck board. In order to reinforce the plate 24, the second ribs 30, 32
Extend in a direction parallel to the edge of the deck board 12.

The second rib 30 has a proximal end connected to the frame 18, a distal end in the extending direction separated from the first rib 28,
A water passage 34 is formed between the end of the rib 30 and the side surface of the rib 28 (water passage 34). The rib 32 has a base end connected to the rib 28, a tip end separated from the frame 18, and
Distance between the tip of 32 and the frame 18 (water passage 36)
36 are formed. Each of the ribs 30 and 32 has a triangular shape having a downward slope toward the tip end thereof.

The deck board 14 has a vertically symmetric structure with the deck board 12. This pallet 10 is used for deck board 14
Is placed on the floor or the like such that the object is on the lower side, the object is loaded on the loading surface P of the deck board 12. Conversely, when the deck board 12 is placed on the floor or the like so as to be on the lower side, the lower surface side of the deck board 14 which is the floor surface in FIG. 1 becomes the object loading surface.

In the pallet 10 configured as described above, the tip of a fork such as a forklift is inserted into the gap between the deck boards 12 and 14, but when inserting the fork, the edges of the deck boards 12 and 14 are inclined. It is composed of plate 24, so the tip of the fork
Is smoothly guided and inserted between the deck boards 12 and 14. Therefore, the efficiency of the pallet transport operation is improved.

Further, since the pallet 24 is provided with an opening 26 for draining water, water and dust hardly collect on the plate 24. In particular, in the present embodiment, since the water passages 34 and 36 are provided at the tip ends of the ribs 30 and 32, these ribs 30 and 32 are provided.
Even if water or dust is applied to the upper part, they are quickly discharged from the opening 26 through the water passages 36 and 34.

Further, in this embodiment, since the ribs 28, 30, and 32 are provided, the pallet 24 has extremely high strength. Then, even if the fork hits the plate 24, the plate 24 is not damaged, and is extremely excellent in durability.

The above embodiment is an example of the present invention, and the present invention may have a configuration other than that illustrated. For example, in the above embodiment, the frame 18 has the flat members 20 and 22,
Such flat members 20, 22 may be omitted. Although the above embodiment relates to a double-sided pallet, the present invention can be applied to a single-sided or skid-type pallet.

[Effects] As described above, the pallet of the present invention is easy to insert a fork, and has good transport work efficiency. In addition, since the drain opening is provided in the plate at the edge of the deck board, the effect that water and dust hardly collect on this plate is also exerted.

In particular, in the pallets according to the second and third aspects, the plate is reinforced with ribs, so that it has extremely high strength and excellent durability. In particular, in the pallet of claim 3,
Despite the ribs, water and dust are reliably discharged from the upper surface of the plate.
