It is a perspective view.

As shown in the developed view of FIG. 2, the table 1 of the present invention has a square (square or rectangular) top plate 2 and first folding lines 3 and 3 on two opposing sides of the four sides of the top plate 2. And two connecting plates 4, 4 connected to each other via the second folding line 5, on the side of the connecting plates 4, 4 facing the first folding line 3, 3.
5 includes two bent leg plates 6 and 6 connected to each other through a joint 5 and two joint leg plates 7 and 7 which are separate from the above-described components. A third fold line 8 is formed at the center of the top plate 2 in parallel with the first fold line 3.

Two insertion lines 9, 9 are formed on the bent leg plates 6, 6 at right angles upward from the bottom (toward the top plate 2), while the joint leg plates 7, 7 are formed at right angles from the top. Two insertion lines 10, 10 are formed downward, respectively. In addition, the insertion line 1 of the joint leg plates 7, 7
The portion P sandwiched between 0 and 10 is piled up in height almost by the thickness of the sheet material.

Each of the above elements is formed of a sheet material of the double-faced corrugated paper 11. The double-sided corrugated paper 11 is shown in FIG.
As shown in (a) and (b), a two-sided corrugated cardboard is bonded, and a liner is bonded to the outside of the one-sided corrugated cardboard.
Between a and 11b, a coarse mountain center 11d and a fine mountain center 11e are doubly present with the central liner 11c interposed therebetween.
In the embodiment, the second fold lines 5 and 5 and the third fold line 8 are
It is formed by a cut line (cut in the broken line portion in FIG. 2 from the back side of the paper) reaching the center 11d of the coarse mountain from the outer liner 11a, and the center 11e of the fine mountain left uncut. And the liners 11b and 11c correspond to double-faced cardboard, which is a hinge portion. The first folding lines 3 and 3 include a plurality of hinge portions 3c in the middle of a cut line 3a completely penetrating the sheet material and sandwiched by two shortcut lines 3b and 3b intersecting the cut line 3a in a T shape. It is formed at the location.

In FIG. 2, the first fold line 3 is mountain-folded so that the connecting plates 4 and 4 and the bent leg plates 6 and 6 are folded on the lower surface of the top plate 2, and further, the third fold line 8 is valley-folded. For example, as shown in FIG. 6, the connecting plates 4 and 4 plus the folded leg plates 6 and 6 and the top plate 2 can be folded compactly in a folding screen state, and the two joint leg plates 7 and 7 are stacked thereon. .

Next, in order to use the table 1 in the folded state, first, the top plate 2 is opened flat as shown in FIG. Then, the bent leg plates 6 and 6 stand upright with respect to the lower surface of the top plate 2. Then, the insertion lines 10, 10 of the joint leg plates 7, 7 are engaged with the insertion lines 9, 9 of the bent leg plates 6, and pushed in, and the bent leg plates 6, 6 and the joint leg plates 7, 7 are connected as shown in FIG. Combine in a girder shape. As described above, the portion P of the joint leg plates 7, 7 sandwiched by the insertion lines 10, 10.
Since the height is piled up by the thickness of the sheet material, the portion P is brought into contact with and supported by the lower surface of the top plate 2 in an assembled state as shown in FIG. Although the cross-sectional view of FIG. 4 is represented by a single double-faced corrugated paper for simplification of the drawing, the double-faced corrugated paper 11 of FIGS. 5A and 5B is actually used.

[0013]

FIG. 8 is a developed view showing a table according to a second embodiment. Note that the same reference numerals are given to portions having the same or the same functions as those of the first embodiment, and description thereof will be omitted.

In the table 1 of the second embodiment, another joint leg plate 7 is additionally provided between the joint leg plates 7 at both ends, and each joint leg plate 7 is connected to two parallel folding lines 7.
It is characterized in that it has a three-dimensional structure that is bent into a triangle in side view at a and 7a. In the table 1 of the second embodiment, the top plate 2 is evenly supported by three joint leg plates 7, 7, 7 and two bent leg plates 6, 6, and the joint leg plates 7, 7, 7 themselves are also three-dimensional. It is suitable when a single double-faced corrugated paperboard is used as a sheet material because of its high strength structure.

Although the present invention has been described with reference to the first and second embodiments, the present invention is not limited to the above-described embodiments. For example, it is possible to fold flat and assemble without the third folding line 8 formed on the top plate 2.
Of course, if the top plate 2 can be bent by forming the third fold line 8, it is undoubtedly the most preferable embodiment in that the folded form becomes compact.

In the first and second embodiments, the sheet material of the double-sided corrugated paperboard 11 or the single double-faced corrugated paperboard is used. However, plastic cardboard made of synthetic resin may be used. Further, various advertisements such as company products and services can be displayed by using the upper surface of the top plate 2 of the first and second embodiments as an advertisement surface. Furthermore, the number of the joint leg plates 7 and the fold line (for example, although not shown, the first fold line 3
Form a fourth fold line parallel to the second fold line 5 and
The connecting plate 4 is bent in a triangle in a side view. In addition, the number of third folding lines 8 is increased. ) Can also be changed.

[0017]

When the table of the present invention is not used, the connecting plate and the bent leg plate can be folded on the lower surface of the top plate, and the joint leg plate can be folded on the upper or lower portion thereof to be folded into a flat shape. In use, it is only necessary to raise the bent leg plate and connect it with the joint leg plate, so that assembly and folding can be performed very easily and quickly. Therefore, there is an excellent use value as a simple table for cherry blossom viewing, athletic meet, picnic and the like. It can also be used as a simple desk for children.

A third fold line is formed substantially at the center of the top plate in parallel with the first fold line, and the upper edge of the joint leg plate intersects with the third fold line in an assembled state. If it is made to abut on the lower surface of the top plate in the direction, the top plate can be folded and further compactly folded. In addition, since the joint leg plate supports and compensates for a decrease in the strength of the top plate due to the formation of the third fold line, the strength in practical use is sufficient.

Further, at least the top plate, the connecting plate, and the bent leg plate are formed of double-sided corrugated cardboard, and the fold line extends from the liner outside the double-sided corrugated cardboard to one core. If it is formed with score lines, thick and strong double-sided corrugated cardboard can be easily folded, and the remaining part maintains high strength equivalent to double-sided corrugated cardboard. It has an excellent effect that there is no possibility that it will occur.
