Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated storage box used in offices and the like.

[0002]

2. Description of the Related Art Conventionally, the storage furniture used in offices and the like has been mainly a completed type assembled in a factory in a predetermined box shape, but since such a completed type is bulky, There is a problem that space efficiency during inventory and transportation is poor and so-called distribution cost increases.

For this reason, there has been an increasing number of assembling types in which plate-shaped parts such as a back plate, side plates, or a top plate are separately completed and then assembled on site.

[0004]

In the conventional assembling type storage furniture, plate-like parts such as a back plate, a side plate, or a top plate are separately packaged, and these plate-like parts are bracketed on site. It is designed to be assembled into a predetermined box shape by connecting with screws or screws.

However, in the case where the individual parts are assembled on site, there is a problem in assembly accuracy unless it is left to a skilled worker. In addition, such a device requires a considerable amount of manpower until it is completely installed after being brought into the field. Therefore, some improvement is desired in the recent situation where labor costs are soaring.

Under the recent construction circumstances, the access time for bringing in and installing furniture in a new building is gradually shortened, and a sufficient space for assembling furniture is secured. Things are getting harder. Due to these circumstances, conventional prefabricated furniture is
There are many points to review.

An object of the present invention is to solve the above problems.

[0008]

The present invention takes the following means in order to achieve such an object. That is, the assembled storage furniture according to the present invention includes a back plate, a top plate hinged to the upper edge of the back plate, side plates hinged to the left and right side edges of the back plate, and both side plates. And a connecting means for connecting the both side plates and the top plate at a position where the top plate is orthogonal to the back plate and the top plate is interposed between the inner edge upper edges of the both side plates. .

In order to surely prevent the interference between the left and right side plates in the folded state and to freely set the depth dimension of the storage furniture, the left and right side edges of the back plate are projected forward. It is preferable to make it into a wall-like body, and to attach the side plates to the front ends of the back plates so as to be foldable at the protruding ends of the left and right edges thereof.

When it is desired to accommodate the top plate between the folded left and right side plates and the back plate without any trouble, the top plate is hinged to the front side of the back plate so as to be foldable, and the left and right edge portions of the back plate are folded. The protrusion size of is set to be equal to or larger than the thickness of the top plate.

The side plate may be hinged to the back plate so as to be foldable toward the front side of the back plate.

[0012]

With such a structure, by folding the back plate, the top plate, and the left and right side plates, the bulky state is almost the same as when the independent plate-shaped components are stacked. It becomes possible to

From this state, the left and right side plates are rotated until they are orthogonal to the back plate, and the top plate is rotated to a position interposed between the upper edge portions of the inner side surfaces of the both side plates. The basic box-shaped structure is completed by connecting the both side plates with the top plate.

Since the rear plate, the side plate, and the top plate can be assembled at the manufacturing stage in this factory, it is easy to maintain the assembly accuracy between the components at a high value. is there. Therefore, it is possible to assemble the shape exactly as designed without resorting to skilled workers on site. In addition, since there are few connecting points, on-site assembly work can be performed quickly.

The procedure for assembling this assembling type storage furniture will be specifically described as follows. First, as shown in FIG. 9, the side plates 3 are rotated until they are orthogonal to the back plate 1.
Further, as shown in FIG. 10, the top plate 2 is rotated to a position interposed between the inner side upper edge portions 3a of the side plates 3. Then, the top plate 2 and the side plates 3 are joined by the joining means 4 shown in FIG. Thereafter, as shown in FIG. 11, the front reinforcing member 5 is joined to the side plates 3 by the joining means 4. Finally, as shown in FIG. 12, when the bottom plate 6 is mounted on the front reinforcing member 5 and the reinforcing ribs 14, the assembly is completed.

With such a structure, the back plate 1
The top plate 2 can be superposed on the front surface 1d of the above, and the side plate 3 in front of the top plate 2 can be packed and transported. Therefore, the bulkiness at the time of inventory and transportation can be reduced like the conventional assembly type. Moreover, assembling at the site can be performed easily and quickly as described above, and can be assembled accurately without resorting to a skilled person. Particularly, in the case of this embodiment, each side plate 3 and top plate 2 are
Since they can be connected to each other by one bolt 25, the assembling work can be performed efficiently. Further, in the present embodiment, since the top plate 2 and the side plate 3 are all folded to the front surface 1d side of the back plate 1, they can be assembled in an upright state. That is, the folded and brought-in item on the site is slightly tilted to the rear side while standing upright, and in that state, the left and right side plates 3 are rotated forward. After that, after returning to a normal standing posture, the top plate 2 is rotated to a horizontal position and the side plate 3 is rotated.
You can combine it with. At this time, if the bolts 25 and 55 can be screwed from the inside of the furniture as in the illustrated embodiment, it is possible to assemble without trouble even in a particularly narrow place. Therefore, it is also possible to directly carry it to a predetermined furniture installation position and assemble it on the spot, and a wide space for assembly is not required.

The screwing structure of the side plate to the back plate is as follows.
The present invention is not limited to the embodiment described above, and may be, for example, one shown in FIGS. 13 to 20.
That is, as shown in FIG. 13, the left and right edge portions 1b of the back plate 1 are projected forward, and the side plates 3 are hinged to the projecting ends through the synthetic resin hinge 111. The side plate 3 can be folded on the inner surface side of the back plate 1 as shown in FIG.

In FIG. 15, the rear edges of the left and right edges of the back plate 1 are hinged to the rear edges of the side plates 3 via hinges 211. As shown in FIG. The back plate 1 can be folded on the back side.

In FIG. 17, the hinge 211 is replaced with a synthetic resin hinge 311. Similarly, the side plate 3 can be folded to the back side 1e of the back plate 1 as shown in FIG. I can do it.

In FIG. 19, the side plate 3 is screwed to the back plate 1 by using the L-shaped hinges 411 pivotally attached to the upper and lower end surfaces of the back plate 1. As shown in FIG. 20, the side plate 3 can be folded to the front face 1d side of the back plate 1, and the side plate 3 and the back plate 1 are folded in the folded state. A space S for interposing a top plate 2 (not shown) is formed between the two.

The present invention is not limited to the embodiments described above, and can be further modified without departing from the spirit thereof.

[0029]

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, it can be folded and handled in a flat and low bulk state at the time of inventory and transportation, and space efficiency can be improved. Moreover, in the field, the side plate and the top plate can be assembled into a casing by simply rotating them to a predetermined angle position and connecting them to each other, so the number of assembly steps can be greatly reduced compared to the conventional assembly type. can do. Further, since the back plate, the side plate, and the top plate can be assembled at the manufacturing stage in the factory, it is easy to maintain the assembly accuracy between the components at a high value.
