Description

[Detailed Description of the Invention] The present invention relates to a pallet with supports that can be stacked without putting a burden on the cargo.

For pallets with supports, it is desirable to lower the supports when not in use in order to increase the efficiency of transporting empty pallets.

Conventionally, as a means of lowering the support column, a raising/lowering type or an insertion/removal type has been implemented.

However, the collapsible column is different from the specially formed fixed column.
The manufacturing cost is high because it is made of square or round tubes that are assembled so that they can be raised and lowered.

In addition, removable support columns are made by fitting ready-made large and small square tubes or large and small round tubes, but there is no one with dimensions that exactly match the inside and outside, so there is a lot of looseness and it is unstable. Sometimes the pillars were lost.

The object of the present invention is to provide a pallet that eliminates the above-mentioned drawbacks of conventional pallets with supports and whose supports can be easily expanded and contracted.

The configuration of the present invention will be explained with reference to the drawings.

FIG. 1 is a front view of the pallet with supports of the present invention when it is in use, and FIG. 2 is a front view when it is not in use. A rectangular frame 1 is provided with telescopic columns 2 at each of its four corners.

At the lower end of the pillar 2 is a plate 3 for preventing displacement during stacking.
is installed.

Each telescopic column 2 consists of a fixed column 4 made of a square tube and a movable column 5 made of a round tube fitted into the fixed column 4 for vertical movement.

Then, at four locations on the outer circumferential surface of the lower end of the round tube movable column 5, there are made holes large enough to fit into the approximately triangular spaces S at the four corners created by the round tube movable column 5 being inscribed in the square tube fixed column 4. There is a protrusion 6.

A notch 7 is provided on each side of the upper end of the fixing column 4 made of a rectangular tube, into which the above-mentioned protrusion 6 can be inserted and engaged.

The fixed column 4 and the movable column 5 are connected by a chain 8.

FIG. 3 shows the details of the state in which the movable column 5 is dropped into the fixed column 4 and the telescopic column 2 is shortened.As shown in FIG. ing.

From this state, the movable column 5 is pulled up until the chain 8 is almost fully extended.

At this time, the protrusion 6 of the movable column 5 protrudes above the upper end of the fixed column 4, but the lower end 51 is still fitted into the fixed column 4.

Next, the movable column 5 is turned 45 degrees to the left or right to align the protrusion 6 with the notch 7, and as shown in FIGS. 5 and 6, when the protrusion 6 is lowered into the notch 7, the movable The column 5 remains in its raised position and holds the telescoping column 2 in its extended state.

The protrusions 6 described above are made of rectangular bar pieces, which penetrate through the movable column 5 in the diametrical direction and are fixed thereto, as shown in FIGS. 4 and 6, and are suitable for heavy-load pallets.

Furthermore, as a protrusion for heavy loads, as shown in FIG. 7 or 8, a round bar piece 61 or a square bar piece 62 is made vertical and its rear half is
It may be fitted into a hole 9 formed in the surface of the movable column 5 and welded.

In the case of a pallet for light loads, as shown in FIG. 9, it is sufficient to withstand the load simply by welding a small piece 63 made of a square or round bar to the outer peripheral surface of the movable column 5 in a shape.

Since the pallet with supports of the present invention has the above-mentioned configuration, the fixed columns (made of square tubes) 4, movable columns (made of round tubes) 5, and protrusions (made of square bars, hexagonal bars, round bars, etc. ) 6 can use commercially available materials as is, resulting in low manufacturing costs, and the round tube has a diameter that can be inserted almost internally into a square tube, so there is no play between the fixed column 4 and the movable column 5. Good stability when stacked.

Expansion and contraction of the column 2 is performed by vertically moving the movable column 5 relative to the fixed column 4 and rotating the movable column 5 by about 45 degrees, which is quick and easy since no screws, tools, etc. are required. It is.

When the column 2 is retracted because it is not in use, the movable column 5 is stored inside the fixed column 4, and since both columns 4 and 5 are connected by a chain 8, there is no risk of losing the movable column 5. Effective as a pallet.
