Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing an assembly-type stand of the present invention.
The assembly-type stand 10 of the present invention is an exhibition stand formed of a columnar rectangular parallelepiped made of paper having an open top and a base and a rectangular cross section. Since the cross section is not rectangular but rectangular frame-shaped, it is clear that it is a hollow columnar rectangular parallelepiped.
In the entire body (length T2 part) 12 in the intermediate region excluding the constant length part T3 from the top of the hollow columnar rectangular parallelepiped and the constant length part T4 from the ground, the four columnar rectangular parallelepipeds It is characterized in that constant width regions on both sides centered on the ridge lines 1a, 1b, 1c, and 1d are folded back inside the columnar rectangular parallelepiped. Since this folded piece extends over the entire length range of the body portion 12, the four top side edge edges of the folded piece are located at the same height. Abbreviated center means that it is not always the center.

In FIG. 1, only the folded piece 121 of the ridge line 1a is shown, but the folded piece is similarly formed on the other ridge lines. The portion on the top side where the folded piece is not formed becomes the load receiving portion 11, and the portion on the ground side becomes the leg portion 13.
The overall height T1 of the assembling stand 10 is preferably about 600 to 1000 mm from the viewpoint of the purpose of exhibition and the ease of picking up the exhibited items. The size of the rectangular frame needs to be large enough to hold the exhibits, and in relation to the overall height, an area that can stably maintain independence is also required.

FIG. 2 is a plan view showing a load receiving portion of the assembled stand. It is a view from the top.
As shown in FIG. 2, four top side edges of the folded pieces 121, 122, 123, and 124 can be seen inside the load receiving portion 11. Since these four edges are located at the same height, they have the characteristic of being able to function as a load receiving portion of the exhibit. It is preferable not to load the load directly on the four edge edges, but to lay a box or a plate material on the four edge edges and load the load on the box body or the plate material. This is to prevent the edges from being damaged and to prevent the exhibits from falling.
The horizontal width H1 and the vertical width H2 of the rectangular frame can be arbitrarily set, but in an extremely flat shape, the strength of the columnar rectangular parallelepiped decreases. Since A4 and B5 size booklets and the like are often placed on the load receiving unit 11, it is necessary to consider the size on which the boxed booklets and the like are placed.

FIG. 3 is a cross-sectional view of the body of the assembled stand.
In the body portion 12, four ridge lines 1a, 1b, 1c, 1d and constant width regions (areas of widths H3 and H4) on both sides having the ridge lines as substantially the center are folded back inside the columnar rectangular parallelepiped. It is preferable to fold back at an angle of 90 degrees with respect to both surfaces sandwiching the ridgeline of the columnar rectangular parallelepiped before folding back (having the ridgeline in between). As a result, the cross section of the body portion 12 is characterized in that it has a cross-shaped dodecagonal frame shape composed of a combination of a concave angle of 90 degrees and a convex angle of 90 degrees. In order to make the concave angle of 90 degrees, H3 and H4 need to have the same width.
Here, the concave angle of 90 degrees means the internal angle of 270 degrees, and the convex angle of 90 degrees means the internal angle of 90 degrees. The length T2 of the body portion 12 is about 400 to 600 mm because it is easy for a walking person to reach out.

FIG. 4 is a bottom view showing the legs of the assembled stand.
As a reinforcing material 131, a box lid-like body having an open ground side is closely attached to the inside of the paperboard material 101 to be incorporated into the leg portion 13. The top plate on the upper side of the box lid should be in contact with the lower ends of the folded pieces 121, 122, 123, 124. The box lid shape does not have to be a complete box lid, and may have a top plate and side plates on four sides. The side plates do not have to be glued together.
The purpose of incorporating the reinforcing material is to strengthen the legs, and a material such as water-resistant corrugated cardboard can be preferably used. The height T3 of the legs may be about 50 to 120 mm.

Here, the size of the folded piece will be examined with reference to FIG.
FIG. 8 shows a rectangular frame having an X on the long side and a Y on the short side. When a folded piece having a length x on one side is formed on the long side X, the length of the remaining side is X-2x. Experimentally, it has been confirmed that X-2x> x is preferable in terms of strength. Therefore, x <(X / 3).
Similarly, y <(Y / 3). Although x and y may have different numerical values, the outer angle of the ridgeline portion cannot be set to 90 degrees in the case of different numerical values as described above.
However, if x and y are too small, practical strength cannot be obtained as a load receiving portion, and therefore, generally, about 20 mm or more is required.

FIG. 5 is a perspective view showing a usage state of the assembled stand.
When using the prefabricated stand 10, a booklet 15 or the like is placed on the load receiving unit 11 and installed in a store, on the street, in a station yard, or the like. It is preferable that the booklet 15 is packed in a booklet box 16 and placed in a box to prevent the booklet 15 from falling or dissipating. Therefore, the size (frontage, depth) of the load receiving portion 11 needs to be determined in consideration of the size of the booklet box 16.

(Embodiment relating to material)
As the paperboard material, in addition to ordinary paperboard, single-sided or double-sided laminated paper with polyethylene or polypropylene can be used, and resin-impregnated paper may be used. It may be double-sided corrugated cardboard or single-sided corrugated cardboard. Although it is called paperboard, it may be a plastic board.
Further, the paperboard material may be colored or patterned.
Single corrugated cardboard or both corrugated cardboard can be used as the reinforcing material of the leg portion 13. It is more preferable if it is water resistant.

Next, a method of manufacturing the assembly-type stand will be described with reference to FIGS. 6 and 7.
FIG. 6 is a diagram showing a mount of the assembly-type stand and a mount of the leg reinforcing member 131, and FIG. 7 is a diagram showing an assembly process of the assembly-type stand.
First, it is a mount for forming a columnar rectangular parallelepiped having both top and bottom openings and a rectangular frame-like cross section, and has a rectangular surface as a first surface, a second surface, a third surface, and a fourth surface. A columnar rectangular parallelepiped ridge line 1a, 1b, 1c, 1d, which has a narrow glue margin portion adjacent to the first surface, and four fold lines parallel to each ridge line, separated by a constant width L5, L6. A step of preparing a paperboard mount having a fold line for forming the folded piece drawn by the ridge and cut lines k1 to k10 which are upper and lower ends of the folded piece at right angles to the ridge line is performed.
Specifically, the paperboard mount shown in FIG. 6 (A) is produced.
Separately from the mount of the stand, a mount of a box lid is produced as a reinforcing material 131 to be fitted into the legs 13 as shown in FIG. 6 (B). As described above, the reinforcing member 131 may have a top plate and side plates on four sides, and it is not necessary to bond the side plates. This material may be corrugated cardboard or the like.

Next, the glue margin portion of the mount for forming the columnar rectangular parallelepiped and the back edge of the second surface are overlapped and adhered over the entire length to form a columnar rectangular parallelepiped having a rectangular cross section shown in FIG. 7 (A). .. Double-sided tape or the like can be used for adhesion.
Next, four regions surrounded by the notch lines k1 to k10 which are the edge edges of the upper and lower folded pieces and the fold lines drawn at a certain width in parallel with the ridge lines 1a, 1b, 1c, and 1d are formed. , The step of pushing into the inside of the columnar rectangular parallelepiped so that the outer angle at the ridge line is 90 degrees to form four folded pieces 121, 122, 123, 124 is performed. As a result, the columnar body shown in FIG. 7B is obtained. In order to make the outer angle of the ridgeline 90 degrees, it is necessary to set L5 = L6. Finally, a reinforcing material is formed in the rectangular parallelepiped space formed under the four ground-side edge edges of the folded piece. Incorporate 131. The reinforcing material 131 can be in the shape of a box lid with the ground side open.
The reinforcing member 131 is pushed in so as to be in contact with the edge of the folded pieces 121, 122, 123, 124 on the ground side. It is preferable that the reinforcing material 131 and the paperboard material 101 are adhered to each other.
It does not have to be glued. As a result, the assembly type stand 10 is completed.

Examples and comparative examples will be described below, but the dimensions and materials of each part of the product as a practical product are not limited to the examples and can be changed without departing from the scope of claims.
(Example 1)
As the material of the prefabricated stand body, a paperboard of 46 size / 40 kg was used, and the mount shown in FIG. 6 (A) was produced. The dimensions of each part are as follows.
Overall width L1 is 933 mm, overall height T1 is 700 mm, body height T2 is 500 mm, load receiving portion height T3 is 100 mm, leg height T4 is 100 mm, rectangular frame long side width L2 is 262 mm, rectangular frame. The width L3 of the short side of the above was set to 190 mm.
Since the widths L5 and L6 from the ridgeline of the folded pieces were equally set to 50 mm, the total width (L5 + L6) was 100 mm.

Separately, as the reinforcing material 131, a box lid-like body made of the mount of FIG. 6 (B) was produced using double-sided corrugated cardboard having a thickness of 3 mm. Since the long side L7 is 260 mm and the short side L8 is 188 mm, the plate surface has a side length shorter than that of the rectangular frame of the main body. It is considered to be fitted inside the leg portion 13. Further, the height T6 was set to 98 mm. The box lid shape is used because it is used without bonding between the side plates.

The glue margin portion of the mount and the back edge of the second surface were overlapped and adhered over the entire length to form a columnar rectangular parallelepiped having a rectangular cross section shown in FIG. 7 (A).
Next, the four regions surrounded by the cut lines k1 to k10, which are the upper and lower ends, and the fold lines, which are the ridge lines 1a, 1b, 1c, and 1d, separated by 50 mm, are the outer angles of the ridge line. It was fitted inside the columnar rectangular parallelepiped so that the angle was 90 degrees to form four folded pieces 121, 122, 123, 124.
Finally, the reinforcing material 101 was fitted into the rectangular parallelepiped space below the four ground-side edge edges of the folded piece without adhering the sides. As a result, the assembly type stand 10 was completed.

(Example 2)
An assembly-type stand having the same dimensions as in the examples was produced except that 46 size / 36 kg was used as the paperboard material. The leg reinforcing material 101 was manufactured and used with the same material and the same dimensions as in Example 1.

(Comparative Example 1)
Assembled stands having the same materials and dimensions as those in the examples but without the folded pieces 121, 122, 123, 124, and having a rectangular cross section were simply produced.
The leg reinforcing material 101 was manufactured and used with the same material and the same dimensions as in Example 1.

The assembled stands completed in Example 1, Example 2, and Comparative Example 1 were subjected to a durability test with a load (printing paper) of 10.5 kg in weight. In Example 1 and Example 2, a load was applied to the load receiving portion 11, but in Comparative Example 1, since there was no load receiving portion, a plate material was placed on the top and a load was placed on the plate material for the test.

In Example 1 and Example 2, there was no change even after 120 hours had passed, but in Comparative Example 1, it was confirmed that the leg portion 13 was deformed. In Comparative Example 1, it is considered that the lower end of the folded piece does not come into contact with the reinforcing material 131, and the paperboard of the leg receives the entire load.
Since the normal weight (mass) of the exhibited item is about 3 to 4 kg, it was confirmed that the assembled stand of Example 1 or Example 2 has sufficient durability.
