Abstract

PURPOSE:To stably take on articles to be loaded when a loading surface is loaded with a plurality of articles in an arranged state, by providing receiving support parts inwardly protruding from the side wall of a leg part or protruding the bottom surface of the leg part. CONSTITUTION:A large number of rib-like receiving support parts 7 having upper surfaces flush with a loading surface 1a protrude from both side surfaces of the leg part 3 at the central part toward the interior of the leg part 3. These receiving support parts 7 prevent a square shape can B from falling to the internal space of the leg part 3 at the central part when said can is loaded on the loading surface 1a. Even when the can B is loaded on the loading surface 1a, the central part of the loading surface is prevented from bending downwardly by the leg part 3 at the central part to have sufficient strength. The mutually opposed parts of two cans B present at the central part are held to the state levitated in the space formed by the leg part 3 at the central part but, since the levitated parts of the cans B are received and supported by the receiving support parts 7, said cans can be stably loaded without falling to the space of the leg part 3 at the central part. Further, the receiving support parts 7 also have function reinforcing the leg part 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a pallet that is integrally formed entirely of a rigid material such as synthetic resin.

[Conventional technology and its problems] Conventionally, cargo receivers have been used as pallets, made entirely of a plate made of synthetic resin or metal, with one or more hollow legs protruding downward from the loading surface. Formed pallets have been proposed (for example, Japanese Utility Model Application No. 61-51335)
.

For pallets that have both left and right ends continuous in the front-rear direction and legs that protrude below the loading surface, when items are loaded on the loading surface, the center portion bends downward, causing strength problems. was there.

Therefore, in the same way as the left and right legs, the legs in the center part are made to continuously protrude downward from the loading surface in the front and back direction, and the loading surface is
The central part was supported by two legs to prevent the central part from bending downward.

However, since the above-mentioned pallet has a space in the center of the loading surface due to the legs, when loading items such as 18V, 1 can or cardboard box, a part of the loaded items may float due to the space. This causes the pallet to become unstable, and when the pallet is moved or tilted, items may fall into the space.

Moreover, articles smaller than the size of this space cannot be loaded.

Therefore, the present invention provides a pallet that can stably load items even when a plurality of items are stacked side by side on the loading surface, and further includes a projecting edge provided on the lower edge of the pallet 18'! , 1 can, and other square cans.

[Means for Solving the Problems] The present invention provides a pallet that is integrally formed of a plate made of a rigid material, and has legs at both left and right ends and at the center that extend downward from the loading surface in the front and back direction. In order to solve the above-mentioned problem, a receiving part is provided in the leg part so that the upper surface thereof is on the same plane as the loading surface by projecting from the side wall and/or from the bottom surface. .

Furthermore, the pallet is provided with grooves for positioning a plurality of objects to be loaded on the m-loading surface at intervals corresponding to the widths of the objects to be loaded in parallel.

[Function] In the first invention, the legs at the center prevent the center from bending downward even when an article is placed on the loading surface. In addition, although there is a space on the loading surface due to the downward protrusion of the central leg, a receiving part is provided that protrudes inward from the side wall of the leg or protrudes from the bottom of the leg. For,
The loaded articles are placed on this receiving part and do not become unstable. Furthermore, this receiving part also plays the role of reinforcing the legs.

In the second invention, the positioning can be performed by fitting the protruding edge of the lower end of the loaded object into the positioning groove, and
Loads can be loaded stably. Furthermore, this positioning groove also plays the role of reinforcing the loading surface.

[Example] Embodiments of the present invention will be described based on the drawings.

In the figure, (A) is made of a relatively hard synthetic resin such as polypropylene resin and polyvinyl chloride resin, or a rigid material such as metal, for example, by press molding or injection molding from a plate. Such a palette is shown.

The pallet (A) of the first embodiment shown in Figs. 1 to 5 can carry, for example, 16 rectangular cans (B) with a capacity of 18 V and a square plane of χ, 4 each on the front, back, left and right sides. It is.

The loading surface area (1) is approximately square, and rising walls (2) of a required height are provided on the four peripheries of the loading surface area (1). Hollow legs (3) whose side surfaces are slightly tapered and continuous in the front-rear direction at both left and right ends and the center of the loading surface area (1).
(4) is formed to protrude downward from the loading surface (la), so that the fork of a forklift can be inserted between the center leg (3) and the end legs (4). It has become.

The upper surface is a loading surface (1a) on both sides of the central leg (3).
) is on the same plane as the rib-shaped support part (7〉) that is on the same plane as the leg part (3
) Multiple inward bulges. This receiving portion (7) prevents square cans (B) from falling into the space within the central leg portion (3) when loaded.

The upper surface of this receiving part (7) is at least 1/2 of the bottom surface of the four square cans (B) loaded in the center of the pallet (A).
Preferably, the legs (
3) It is desirable to form a bulge in the shape of an inward herb.

On the loading surface (1a), there is a protrusion (
A shallow linear positioning groove (5) for fitting the B1)
) (5a) is provided so as to bulge out on the back surface.

Five linear positioning grooves (5) (5a) are provided in the left-right direction from the left end to the right end of the loading surface (1a) for each width interval of the square cans (B), and in the front-rear direction. Four grooves (5) and (5a) for positioning in the left and right direction are provided to intersect with each other at right angles. When 16 cans (B) are loaded along the positioning groove (5) (5a), they are loaded along the dashed-dotted line shown in FIG. In addition, the loading surface (1a
The four positioning grooves (5a) on the four circumferential edges of ) need only have a width that allows at least one protrusion (B1) to fit therein, and the positioning grooves (5) in other parts have at least It is sufficient if there is a width that allows the two projecting edges (B1) to overlap and fit together.

The left and right positioning grooves (5) are located on each leg (3) (4)
It is interrupted by (4). The end of this interrupted positioning groove (5) is continuous with a reinforcing circular rib (6) that bulges in the vertical direction on the side surface of each leg (3) (4) (4).

Furthermore, reinforcing ribs (8) are provided on the loading surface (la).
A plurality of grooves are provided in parallel with the positioning groove (5) in a grid pattern so as to bulge out on the back surface. This rib (8) is similar to the positioning groove (5) on each leg (1) (4) (4
), but this broken end is continuous with a reinforcing circular rib (6) that bulges in the vertical direction on the side surface of each leg (1) (4) (4). Furthermore, on the bottom surface of the central leg (3), there is a circular rib (9) that bulges upward in the front-rear direction and is continuous with the vertical rib (6) that bulges out from the front and rear surfaces of the leg (3). ) is provided.

The method of using the pallet (A) of the above embodiment will be explained below.

As shown in FIG. 4, the protrusion (B1) on the lower edge of the square can (B) is connected to the positioning groove (shown by the dashed-dotted line in FIG. 2).
5) and load a total of 16 square cans (B), 4 each on the front, back, left and right, on the loading surface (1a).

Even when the can (B) is placed on the loading surface (1a), the central part of the loading surface (la) does not bend downward due to the legs (3) at the center and has sufficient strength. The mutually opposing parts of the two cans (B) in the center are connected to the legs (3) in the center.
), but since the floating part of the can (B) is supported by the supporting part (7), it will fall into the space of the central leg part (3). It can be loaded stably without any problems. Furthermore, it also serves as reinforcement for the legs (3).

In addition, the positioning grooves (5) provided in a grid pattern make it easy to determine where to place the cans (B), and even when the pallet (A) is tilted or moved, the cans (B)
will not fall down. As a result, there is no need to tighten the straps more than necessary, which improves work efficiency.

Furthermore, with each of the three legs (1) (4) (4),
The pallet (A) can be stably placed on the ground, etc., and the loading surface (
This also serves as reinforcement for 1a). When the fork of the forklift is inserted between the legs (3), (4), and (4), the fork does not shift to the left or right, so the pallet (A) does not shake when the forklift is moved.

In addition, since each of the legs (3) (4) (4) is provided in a tapered shape, empty pallets (A) when not in use can be stored by stacking them low, saving space.

In this example, a shallow linear positioning groove (5) was provided on the loading surface (1a) in order to load square cans (B) having a protruding edge (Bl) on the lower edge. However, when loading small articles with flat bottoms, such as cardboard boxes, the positioning groove (5) is not necessarily necessary, and the receiving portion (7) alone can be used to ensure stable loading.

Figures 6 and 7 show a pallet (A) of the second embodiment, in which square cans (B) with a rectangular plane are arranged four times in the front and back direction.
20 pieces in total, 5 pieces on the left and right sides.

The loading surface (la) of this pallet (A) is rectangular,
Hollow legs (3) (4) (4) with slightly tapered sides are continuous in the front-rear direction from both left and right ends and from the center to the center of the loading surface area (1). It is formed to protrude downward from 1a).

A trapezoidal support H (10
) protrudes continuously in the front-rear direction, and this trapezoidal support part (
The upper surface of 10) is on the same plane as the loading surface (1a).

Both sides of the central leg (3) and the trapezoidal support part (10)
A plurality of inner helical receiving portions (7) bulge out on both sides of the container as in the previous embodiment, and the upper surface of these receiving portions (7) is formed on the same plane as the loading surface (1a). There is.

In addition, on the upper surface of the loading surface (1a) and the trapezoidal receiving portion (10), there is a lattice-like positioning groove <5) (5a ) is provided.

Furthermore, reinforcing ribs (6), (8), and (9) are provided on both sides of the loading surface (1a) and legs (3), (4), and (4), as well as on the bottom of the legs (3) in the center. It is being

When square cans (B) are loaded on this pallet (A), the four cans (B) in the center are loaded on the trapezoidal receiving portion (10). The four cans (B) in the center and one side of the cans (B) on both sides are in a floating state due to the space of the legs (3) in the center. However, since the floating part of the can (B) is supported by the support part (7), the can (B) can be stably loaded without falling into the space.

In this embodiment, the receiving portion is provided in the central leg portion (3), but the present invention is not limited to this, and receiving portions may be provided in each of the left and right legs # (4). Further, although the pallet (A) on which square cans (B) are loaded has been described, the pallet is not limited to this, and may be a pallet on which cans with a rectangular shape or cans with a round shape can be loaded.

[Effects of the Invention] In the first invention, the legs at the center prevent the center from bending downward even when an article is placed on the loading surface, thereby providing sufficient strength. In addition, although there is a space on the loading surface due to the downward protrusion of the central leg, the loaded items are loaded on the receiving part that bulges inside the leg, so that it does not become unstable. This makes it possible to load items smaller than the size of this space, even if they have collapsed inside the legs. This receiving part also serves as reinforcement for the legs.

In the second invention, the articles to be loaded can be easily positioned by fitting the protrusion on the lower edge of the article to be loaded into the positioning groove, and the loaded articles can be more stably placed. There is no need to tie more bands than necessary, or to secure items to the pallet using backing plates, protectors, etc., which improves work efficiency. Furthermore, this positioning groove also plays the role of reinforcing the loading surface.
