Description

[Detailed description of the invention] Industrial field of application This invention is a pallet used when quadrilateral pallets used for cargo handling operations such as fork lifts are stacked up and down in multiple tiers with the required amount of cargo loaded.・Regarding supporters.

Prior art and its problems In general, this type of pallet supporter consists of a pair of support frames made of metal pipes or the like that are formed in a downward U-shape from a horizontal rod portion and leg rod portions on both sides. By erecting the leg rods on both sides on the diagonal corners of the quadrilateral pallet via mounting brackets, etc., the horizontal rods of both support frames are arranged to intersect with each other above the pallet. .

However, if the total height of the cargo loaded on the rectangular pallet is low, for example, the height of each individual cargo is low and it is impossible to stack them due to strength or stacking stability, or it is impossible to stack them above a certain level. In this case, a dead space is formed in the upper part of the inner space of the pallet supporter, which reduces the space utilization rate when storing pallets in multiple stacks in a warehouse, etc. There was a problem in that cargo handling efficiency decreased due to a decrease in cargo volume.

Means to Solve the Problem This invention has a pallet supporter with a structure that allows the installation of horizontal shelves, and when the total height of the cargo stacked on the pallet is low, the horizontal shelves can be attached to create multi-tiered cargo. It is possible to solve the dead space by separating cargo or loading different types of cargo on horizontal shelves, thereby improving space utilization and cargo handling efficiency.In addition, the shelf holders for installing horizontal shelves can be attached and removed. The purpose is to be flexible and to provide good installation stability.

That is, for the above purpose, the pallet supporter according to this invention is formed in a downward U-shape from a horizontal rod portion and hollow leg portions on both sides, and the hollow leg portions on both sides are aligned with the diagonal angle of the quadrilateral pallet. A pair of support frames are installed vertically on the pallet so that the horizontal rods intersect with each other above the pallet.
A shelf support bar is provided horizontally between the hollow leg rods on the sides, and each of the shelf support bars is inclined diagonally downward from the base end side to the front side of the bar body at both ends of the bar body. A locking rod having a substantially dogleg shape when viewed from the side is protruded by the inclined portion and the hanging tip portion that hangs down continuously from the sloped portion, and the locking rod of the shelf support beam is provided on the circumferential surface of each hollow leg rod portion. It is provided with a vertically long locking hole that can be inserted into the inside.

Embodiments Hereinafter, this invention will be explained based on illustrated embodiments.

In the figure, 1 is a quadrilateral pallet for cargo handling, 2
A pair of support frames 3, 3 and a plurality of shelf supports 4, 4...
The pallet supporter 5 is comprised of four mounting fittings for mounting the pallet supporter 2 on the pallet 1. Each support frame 3 has a horizontal rod part 6 made of a metal pipe, and hollow leg parts 7, 7 on both sides whose upper ends are inserted into short cylinder parts 6a, 6a projecting downward from both ends of the horizontal rod part 6. It is structured in a letter shape. By erecting both support frames 3, 3 with their respective leg rod portions 7, 7 at diagonal positions of the pallet 1 via the mounting brackets 5, the mutual horizontal rod portions 6, 6 can be attached to the pallet 1 at diagonal angles. They are arranged so as to intersect at the top.

Each shelf support bar 4 has locking rods 9, 9 made of metal rods protruding from both ends of a crosspiece body 8 made of a square pipe by welding. A sloped portion 9 that slopes diagonally downward toward the front side of the
a and a drooping end portion 9b that hangs down continuously from the lower end portion 9b to form a substantially dogleg shape in side view. However,
These shelf support bars 4 have vertical locking holes 10 bored in the circumferential surfaces of the hollow leg rods 7, 7 between the hollow leg rods 7, 7 on the two opposing sides of the pallet 1, respectively. , 10 by fitting and inserting the locking rods 9, 9 at both ends thereof, it is installed horizontally at the inner position of both hollow leg rods 7, 7 so that both sides are at the same height.
Reference numeral 11 denotes a horizontal shelf placed on the shelf supports 4, 4 on both sides.

Each of the locking holes 10 of the hollow leg rod portion 7 has a shape such as an ellipse in which the vertical length is slightly longer than the horizontal length, and the horizontal length, that is, the width in the horizontal direction is approximately the same as or slightly larger than the diameter of the locking rod 9. A plurality of hollow leg rods 7 are provided at required intervals in accordance with the required number of shelf mounting stages.

The shelf support bar 4 is installed by supporting the shelf support bar 4 in a state in which the hanging ends 9b, 9b of the locking rods 9, 9 are forward and approximately horizontal, and inserting both hanging ends 9b, 9b into the locking holes 10. , 10 horizontally, the entire shelf support bar 4 may be rotated upward about 90 degrees around the locking rods 9, 9. As a result, each locking rod 9 has its hanging end portion 9b facing downward as shown in FIG. It won't come off unless you do.

In this installed state, the upper surface 8a of the crosspiece main body 8 becomes a horizontal surface, and can support the horizontal shelf 11 in a stable state, and the weight of the horizontal shelf 11 and the cargo loaded thereon locks the inclined portion 9a of the locking rod 9. Because it acts downward so as to bite into the hole 10, the shelf support bar 4
The mounting condition becomes more stable. In addition, when the horizontal shelf 11 becomes essential due to the total height of the cargo, or when the pallet supporter 2 is removed from the pallet 1 for storage or transportation, each shelf supporter 4 should be moved in the opposite direction from when it was installed. It can be easily removed by rotating downward. Therefore, this pallet supporter 2 can be used with shelves or without shelves depending on the total height of the cargo loaded on the pallet 1, and the number of shelves in the state with shelves can also be changed. The dead space inside the supporter can be eliminated to greatly improve the space utilization rate and cargo handling efficiency, and moreover, a stable loading state can be realized without fear of the horizontal shelf 11 falling off carelessly.

In the above embodiment, an example is shown in which the bar body 8 of the shelf support bar 4 is a square pipe, but the bar body 8 may have other shapes such as a round pipe or an angle material. Further, in this invention, the number of locking holes 10 provided in each hollow leg portion 7 of the support frame 3 may be one, and the number of shelves may be one.

Effects of the invention The pallet supporter according to this invention is equipped with removable shelf supports, and by using the shelf supports to install horizontal shelves, pallets can be configured in multiple stages. Therefore, when the total height of the cargo to be loaded on the pallet is low, it is possible to load the cargo on the horizontal shelf as well to eliminate the dead space inside the pallet supporter, thereby improving space utilization. On the other hand, if the total height of the cargo is high, it is also possible to remove the shelf supports and use it in the normal usage mode. In addition, the above-mentioned shelf support beam is installed between the hollow leg portions of the support frame via locking rods of a specific shape that protrude from both ends of the crossbody body, so it is difficult to connect the horizontal shelf and the load on it. The weight of the loaded cargo makes the installed state more stable, and there is an advantage that it can be easily attached and detached by rotating the structure. In addition, this pallet supporter can be easily manufactured at low cost because both the structure of the shelf support itself and the structure for mounting it are extremely simple.
