Description of the Related Art In a storage pallet in which a square tube is established at each corner of a pallet body so that an article placed on the pallet body is protected by this, for example, an article such as an engine is placed on the storage pallet. It is used for when exporting to overseas. With this type of storage pallet, when it is emptied and returned, it is folded by folding it inward and the volume is reduced (hereinafter referred to as "compact") to reduce transportation costs, storage costs, etc. I have to.

[0003]

However, in the conventional storage pallet, it is difficult to fold a heavy square tube unless it is lifted by hand when folding, so it is a heavy labor. It is a heavy burden on the operator because it is easy to handle when handling.

Further, since the volume cannot be changed according to the height of the article, there is a problem that it is not versatile.

The present invention solves the above problems, and an object thereof is to provide a storage pallet that can be easily folded. Another object of the present invention is to provide a storage pallet whose storage volume can be easily increased or decreased.

[0006]

For this purpose, the storage pallet of the present invention is provided with a square tube on the pallet body, and the square tube is divided into a lower base portion and an upper main portion near the root, and the base portion is divided into two parts. The main part is supported by a horizontally inserted support shaft so that the main part can be tilted only inward, and a horizontal surface and an inclined surface continuous with the horizontal surface are formed at the upper end of the base part. By forming a horizontal surface and an inclined surface that are in surface contact with the horizontal surface and the inclined surface, respectively, the main portion can stand on the base portion.

In the storage pallet of the present invention, a square tube is provided upright at each corner of the pallet body, a cutout groove is formed in the upper end opening of the square tube, and the upper end opening is stored in the hollow portion of the square tube. A protrusion that can be freely retracted from and arranged is disposed, and a protrusion piece is formed on the peripheral wall of the cylinder so as to fit in the square tube by being positioned at the corner of the square tube, and the protrusion piece is engaged with the cutout groove. The feature is that the cylinder can be extended.

[0008]

When the storage pallet is to be made compact, the main part is simply pushed to bend and fall inward. On the other hand, at the time of assembly, if the main part is erected, a horizontal plane and an inclined surface continuous with the horizontal plane are formed at the upper end of the base part, and the lower end of the main part is configured to make surface contact with them. The club is self-reliant. Therefore, the assembling work can be easily performed.

Further, since a cylinder which is housed in a hollow cylinder having a hollow portion and which can be freely retracted from the upper end opening is arranged, when the volume of the article is large, this cylinder is pulled out and the projection piece is used as a square cylinder. The storage capacity can be easily increased by engaging with the notch groove.

At the four corners of each corner of the pallet body 1, square tubes 2 are fixed by joining pieces 5 having a plane L shape.

Each of the square cylinders 2 has a lower base portion 3 near the base thereof.
And an upper main part 4 are divided. The base portion 3 extends below the pallet body 1 and has a bowl-shaped grounding portion 6 at its lower end.
Are formed.

A planar U-shaped connecting member 7 is fixed to the outer periphery of the lower end of the main portion 4 by welding, a supporting shaft 8 is horizontally provided at the lower end of the connecting member 7, and the supporting shaft 8 serves as the base 3 The main part 4 is loosely inserted into the shaft hole 9 formed in the upper side wall of the
Is configured so that it can be tilted only inward with the support shaft 8 as a fulcrum.

As shown in FIG. 3, a horizontal surface 10 is formed on the upper end of the base portion 3 in about half thereof, and an inclined surface 11 having a slope of about 15 degrees is formed in the other half thereof, and at the lower end of the main portion 4. Similarly, a horizontal surface 10 'is formed in about half, and an inclined surface 11' having a slope of about 15 degrees is formed in the other half.
The horizontal surface 10 'comes into surface contact with the horizontal surface 10 and the inclined surface 11' comes into surface contact with the inclined surface 11, whereby the base portion 3
The main portion 4 is self-supporting on the upper side, and when an external force in the direction of the arrow is applied as shown in FIG. 2, the contact surface slides so that the main portion 4 can be tilted.

Reference numeral 12 designates a cylinder housed in the main portion 4 having a rectangular tube shape. The upper end of the main portion 4 is opened, and the column 12 is structured so that it can be pulled out from the upper end opening.

A constricted portion 13 having a small outer diameter is formed at a substantially central position of the column 12, and a rotatable member 14 having a cylindrical short tube is rotatably fitted to the constricted portion 13 as shown in FIG. It is crowded. Two projecting pieces 15, 15 are formed on the outer periphery of the rotating body 14 at diagonal positions. When the rotating body 14 is rotated to locate these projecting pieces 15, 15 at the corners of the main part 4, the rotating body 14 is rotated. 14 can be earned in the main part 4 as shown in FIGS.

Further, on the peripheral wall near the lower end of the column 12, projections 16, 16 are formed which travel in the axial direction. However, unlike the projection pieces 15 and 15, the projection pieces 16 and 16 are directly fixed to the column 12. Therefore, the projection pieces 15, 1
5 can be accommodated in the main portion 4 by rotating the cylinder 12 itself and positioning it at the corner of the main portion 4.

Notched grooves 17, 17 are formed in the upper end opening edge of the main portion 4 and are elongated in the vertical direction. When the projection pieces 15, 15 or the projection pieces 16, 16 are engaged with the cutout grooves 17, 17, the column 12 can be held in a state of protruding from the upper end opening of the main portion 4. That is, these projection pieces 15, 15 or the projection piece 1
By engaging the grooves 6 and 16 with the notches 17 and 17, the elongation of the column 12 can be adjusted in two steps.
