Prior Art and its Problems Greenhouses are primarily used in the winter and are often not needed in the summer. Also,
Storage sheds, bicycle parking lots, etc. are often used only during rainy days or at night, and are often not needed during the daytime on sunny days. Therefore, foldable and easily assembled buildings as shown in FIG. 7 have conventionally been used as greenhouses, storerooms, bicycle storage areas, etc. This foldable simple assembly building 21 is
A pair of left and right support members 22 are attached to the wall W of the house at a predetermined interval in the left-right direction at approximately the same height as the ground G, and a plurality of support members 22 are approximately U-shaped and have both ends pivoted to the support members 22. The seat support frame 23 is made up of a seat support frame 23, and a seat 24 stretched across all the seat support frames 23, and when the seat 24 is stretched out, it forms approximately four semicircles when viewed from the side. However, with such a simple assembly building 21, it is not possible to cover a tall object as shown by the chain line A in FIG. It was necessary to increase the size of the building, which created a problem in that a wasted space 25 was created within the building 21. Therefore, as shown in FIG.
It has been considered that the seat support frame 23 is moved a predetermined distance above the ground G and attached to the wall W, and the seat support frame 23 at the lower end is rotated further downward. However,
In this building 21, the distance l between the lower end and the wall W
is smaller than that shown in FIG. 7, and there was a problem that it was impossible to store items with a large width in the front and back direction. Moreover, there was a problem in that a large gap 26 was formed between the seat support frame 23 at the lower end and the wall W.

The purpose of this invention is to provide a foldable and easily assembled building that solves the above problems.
