Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal plate shelf and a metal plate wagon.

[0002]

2. Description of the Related Art A metal plate shelf is generally called a steel shelf, and a metal plate is bent to form a support column and a shelf plate, which are assembled to form a shelf. The metal plate wagon is also called a steel wagon, and casters are attached below the columns to make the steel shelves movable.

Metal plate wagons are used in various fields. For example, it is used to carry tools and products in factories, prepare materials and lab tools in laboratories and carry them to necessary places, and carry food and tableware in cafeterias.

It is convenient that the metal plate shelves and the metal plate wagons for the above-mentioned applications have an open structure. The open structure is a structure having no wall, and an article can be placed on the shelf from any direction, and an article on the shelf can be taken out from any direction. Such a structure is composed of a plurality of shelves and four columns that support the shelves at the four corners. This structure has a large volume when assembled, but it has a small volume when disassembled. Therefore, it has been considered to be assembled and used at the place of use for convenience of storage and transportation. Also, the assembly work at that time was required to be as simple as possible.

Therefore, the conventional metal plate shelf is shown in FIG.
It was assembled as shown in. In FIG. 1, a metal plate shelf is assembled by connecting four columns A and three shelf plates B with bolts C. The pillar A is a metal plate bent in an angle, and the shelf B is a metal plate bent in a shallow rectangular box shape. Shelf board B
Up the pillars A at the four corners of the shelf, and make the corners of the four corners of the shelf B closely contact the angle inner surfaces of the pillars, and fix the contact surfaces with the bolts C.
It should be a shelf.

In this type of shelf, in order to simplify the assembling work, as shown in FIG. 2, two bolts C are used at each corner. That is, only one bolt C is used for one shelf plate on each surface of the column A, and this is fixed with a nut. This is also due to the fact that each surface of the column A was not wide enough to use a plurality of bolts C.

Since the shelf B has a shallow box shape, there is a risk that the tip of the portion corresponding to the side wall may hurt the hand.
In that case, the tip was folded back to round the tip. However, in that case, the folded back was only folded back to the inside of the box-shaped body, and was not folded back to the outside. Also, the folding back was extremely narrow.

The metal plate shelves assembled as shown in FIG. 1 have a drawback in that, when an object is placed on the shelves, the columns are easily tilted when a lateral force is applied. This drawback became more prominent when a caster was attached to the lower part of the column and a metal plate shelf was used as a wagon. That is, when an article is placed on a metal plate wagon and is to be moved, the column is tilted by a slight force to distort the shape of the wagon.

Therefore, as shown in FIG. 2, it was attempted to abut the metal plate or synthetic resin L-shaped reinforcing material D on the inside of the shelf board B and tighten it with bolts C. I couldn't prevent it.

[0010]

SUMMARY OF THE INVENTION The present invention seeks to remedy the above-mentioned drawbacks. That is, the present invention keeps the assembly work as simple as before,
The purpose is to prevent the columns from tilting even when a force is applied laterally to the metal plate shelf or the metal plate wagon.

The inventor has attempted to overcome the above-mentioned drawbacks by improving the shelves. This inventor has a shallow box-shaped shelf, so the tip portion corresponding to the side wall of the box is folded back to the outside, the folded-back portion is notched at the four corners, and the notched ends of the folded-back portion just hit the side surfaces of the column. By doing so, it was found that the tilt of the column can be completely prevented by simply bolting this shelf plate as in the conventional case. The present invention has been completed based on such knowledge.

The present invention comprises a plurality of shelf plates formed by bending a metal plate into a shallow rectangular box shape and four pillars formed by bending the metal plate in an angle. , A metal plate shelf assembled by abutting the corners of the four corners of each shelf plate to the inner surface of the column and fixing them with bolts, a small piece of metal plate is placed outside each edge piece extending in the thickness direction of each shelf plate. A metal plate shelf is provided, wherein the side surface of the column is closely attached to the side surface in the thickness direction of the metal plate piece, and both side surfaces of the column are sandwiched between the side surfaces of the metal plate piece. is there.

The present invention also provides a wagon in which casters are attached below the metal plate shelves so that the metal plate shelves can be moved. That is, the present invention comprises a plurality of shelf plates formed by bending a metal plate into a shallow rectangular box shape, and four support posts formed by bending the metal plate into an angle. , A metal plate shelf assembled by fixing the corners of the four corners of each shelf plate to the inner surface of each strut and fixing them with bolts, a small piece of metal plate outside each edge piece extending in the thickness direction of each shelf plate. Attach the side of the pillar to the side in the thickness direction of the metal plate piece, sandwich both sides of the pillar with the above-mentioned side surfaces of the metal plate piece, and attach casters below each pillar to make the metal plate. The present invention also provides a metal plate wagon, which is characterized in that the shelves can be moved.

When the shelf board 1 used in the present invention is expanded, as shown in FIG. 3, a rectangular parallelepiped board P is formed.
Edge pieces 12, 1 of width x on the four sides of the flat plate 11 made of QRS
3, 14, 15 are attached, and width y is attached to each edge piece.
The folding pieces 16, 17, 18 and 19 are attached. Each folding piece 16, 17, 18, 19
Both ends are notched by a rectangular portion 20 having a length z. Here, the width y is made slightly smaller than the width x. Also, the length z is made equal to the width of the column, as will be explained later.

The shelf board 1 used in the present invention is made by bending the metal plate shown in FIG. 3 as shown in FIG. In FIG. 4, the folding pieces 16, 17, 18, 19
Are in the same direction with respect to the flat plate 11, and are edge pieces 12, 1 respectively.
First, it is folded back so as to overlap with 3, 14, and 15. Then, the edge pieces 12, 13, 14, and 15 are bent so as to stand upright with respect to the flat plate 11 together with the folded pieces, as shown by the edge piece 12, and the entire box shape is shallow. Become a body. At this time, the folding pieces 16, 17, 1
Bend each edge piece so that both 8 and 19 are outside the box-shaped body.

The shallow box-like body thus produced is then provided with bolt holes for connecting with columns at the corners corresponding to the side walls of the corners of the four corners, and becomes the shelf board 1 usable in the present invention. Since this shelf board 1 is characterized by the structure of the corner portions at the four corners, the corner portions are enlarged and shown in FIG.

The shelf board 1 shown in FIG. 5 has a shallow box shape having a flat plate 11 as a bottom and edge pieces 12 and 13 as side walls. Since the width y of the folded pieces 16 and 17 is made slightly smaller than the width x of the edge pieces 12 and 13, the edge pieces 12 and 13 are formed.
The folding pieces 16 and 17 folded back along the
At least the upper half of the edge pieces 12, 13 are covered, and the lower ends of the folding pieces 16, 17 are located slightly above the lower ends of the edge pieces 12, 13. Since the folding pieces 16 and 17 are cut out at the corners of the shelf only in the rectangular portion having the length z, the edge pieces 12 and 13 are exposed only in the rectangular portion having one side z. At the center of each exposed portion, the above-mentioned bolt holes 41, 42 are provided.
Is provided.

On the other hand, the column 6 has an angled shape and is composed of two pieces 61 and 62 which are orthogonal to each other, and each piece 61 and 62 has the same width. Since this width is the length z, when the support column 6 is brought into contact with the corner portion of the shelf board 1, the side surfaces 63 and 64 of the support column 6 are cut by the folding pieces 16 and 17 as shown in FIG. The side surfaces 161 and 171 thus formed are in close contact with each other. Thus, the column 6 is sandwiched between the folding pieces 16 and 17 on both side surfaces 63 and 64. In this state, the bolt holes are aligned with each other, the bolts are inserted therethrough, and the nuts are fitted to connect the support columns 6 and the shelf board 1.

When the shelf plate 1 and the supporting column 6 are fixed with bolts in this manner, the supporting column 6 is folded back to form the folding piece 1 as shown in FIG.
It will be closely sandwiched between 6 and 17. At this time, if the widths of the folding pieces 16 and 17 cover more than half of the widths of the edge pieces 12 and 13, both side surfaces 63 and 6 of the supporting column 6 are covered.
4 comes into close contact with the side surfaces 161 and 171 of the folding pieces 16 and 17 over a considerable length, so that the column 6 has no room for tilting with respect to the shelf board 1.

In FIGS. 3 to 6, the folding pieces 16, 1 are shown.
7, 18, 19 are edge pieces 12, 13, 14, 15 respectively
The example in which the side surfaces 161, 171 and the like that are to be attached integrally with and are to be brought into close contact with the support pillar 6 is formed by folding back. However, the parts corresponding to the side surfaces 161, 171 and the like can be provided without folding. For example, as shown in FIG. 7, small pieces 31 and 32 of a metal plate are prepared in advance, and the metal plate made by cutting is formed on the outer surface extending in the thickness direction of a conventional shallow box-shaped shelf plate. Pieces 31, 3
Sides 3 to which 2 should be attached by welding, etc. and should be closely attached to the support
It is also possible to form the shelf board 1 by forming 11 and 321.

Thus, according to the present invention, a plurality of small pieces of metal plate are attached to the outside of the shelf plate along the surface extending in the thickness direction, and the side surface of the small piece of each metal plate extending in the thickness direction is supported. Of the metal plate is required to be sandwiched between the side faces of the metal plate.

The shelf board 1 can be used as a dish-like one having a spill stopper in the periphery by fixing the shelf 11 with the flat plate 11 downward to form a box-shaped body. When the box-shaped body described above is reversed and the flat plate 11 is turned up and the shelf plate 1 is fixed to the support column 6, it can be used as a flat plate without spill stopper.

FIG. 8 is a metal plate according to the present invention, which is assembled by fixing the uppermost tier to a dish shape and the lower two tiers to a flat plate and fixing a total of three shelf boards 1 to four struts 6. The shelf is shown. Further, in FIG. 9, similarly, the uppermost tier is made into a dish shape, and the lower two tiers are flat plates, so that a total of three shelf boards 1 and four support pillars 6 are provided.
1 shows a wagon according to the present invention, which is made by attaching a flexible caster to the lower part of each column.

[0025]

According to the present invention, the shelf plate is formed into a shallow box shape as in the conventional case, and a small piece of a metal plate is attached to the outside of the surface extending in the thickness direction of each shelf plate, and the metal plate extending in the thickness direction of the shelf plate is attached. Since the shelves are made so that the sides of the plate pieces come into close contact with the side surfaces of the columns, simply by fixing the shelf plates and the columns with bolts, the two sides of the columns are placed between the side faces of the metal plate pieces. Sandwiched between
The columns can be prevented from tilting with respect to the shelves.
Therefore, it is possible to obtain a metal plate shelf and a metal plate wagon that are not easily tilted by the conventional assembling operation only by improving the shelf plate. In this respect, the effect of the present invention is great.
