Is rotatably attached to the frame body 97 at its upper part. At the time of transportation or storage, as shown in FIG. 11A, other components are folded and overlapped on the bottom wall 94, and the whole is in a thin and flat plate shape. In order to assemble this container 91, first, as shown in FIG.
And then pull up the frame 97 as shown in FIG.
By rotating the side walls 96 and 96 outward and fitting the lower sides to the side edges of the bottom wall 94, as shown in FIG. When the container 91 is assembled, the container 91 is stably fitted when the upper and lower surfaces are stacked, and the container 91 can be folded by a procedure reverse to the above-described assembly. If this container is used upside down, it becomes an exhibition stand.

[0004] However, in these display stands, the top plate and the support portion are separate bodies, and it is necessary to always pair them, and it is inconvenient to assemble, and the number of parts is increased. In order to solve these problems, there is a display stand described in Japanese Utility Model Publication No. 3-40210 previously developed by the present applicant. FIG. 12 shows the display stand. FIG.
FIG. 12A is a perspective view immediately after the start of folding, and FIG. 12B is a perspective view immediately before the end of folding. The display stand 71 has a front panel 72 having a horizontally long rectangular shape on the front and side panels 73R and 7 having a size such that the front panel 72 is divided into two sides.
3L is screwed on each side end so as to form a substantially U-shape in a plane, and a front end is screwed on an upper side of the front panel 72 and L-shaped locking portions are formed symmetrically on both lower surfaces. 74, and a shelf panel 75 supported on the inner surfaces of the front panel 72 and the side panels 73R and 73L. In use, the top panel 74 in the state shown in FIG.
And the shelf panel 75 is mounted on the locking rod 79 to assemble the table. At the time of folding, first, from the state shown in FIG.
Is raised and turned upside down and turned 270 degrees to overlap the front surface of the front panel 72, and the shelf panel 75 is removed, and the L-shape of the top panel 74 is set in the posture shown by the dashed line in FIG. The top panel 7 is locked by the locking portion 78.
It is sufficient to store it overlaid on 4. In this way, the display stand has a front panel 72, side panels 73R and 73L, and a top panel 74.
Are integrated, so there is no longer any need to be careful to keep them in pairs so that they do not fall apart.

[0005]

However, when this display stand is assembled and folded, the top panel 74 is turned by 270 °.
The display stand had to be raised once during the rotation, which was cumbersome. One of the reasons is that elderly people and women, etc., who are not very powerful, can not assemble the display stand alone, and the second reason is that the folded display stand is loaded on a narrow trolley. This is because it is not easy to assemble the best display stand as it is. In the case of the former, this work can be performed by only a weak person if it is not necessary to raise the display stand during the assembly, but a strong person is required if the display stand is raised halfway. In the latter case, carts are often used in recent years, such as folding display stands, loading them on carts, transporting them to warehouses, and placing them in warehouses while loading them on carts. Therefore, if it is possible to assemble display stands one after another with the display stands still loaded on the trolley, it is convenient to take the assembled display stand out of the trolley without taking up space. However, if it is necessary to raise the display stand once during assembly, a separate work space and personnel are required to lower the display stand from the trolley and continue assembly, and there are significant differences in workability and cost. . Therefore, the object of the present invention is to solve the above-mentioned problems, and it is a compact and low-cost display stand having a small number of parts, which does not require dispersing the components of the display stand, and especially a truck. An object of the present invention is to provide a folding display stand that can be easily assembled while being stacked on a floor and has a good appearance.
