FOLDABLE/COLLAPSIBLE STRUCTURES

摘要

The present invention relates to a collapsible/foldable structure that ma y include a top roof and a bottom platform. A pair of sidewalls may be provi ded each of which may be pivotally attached to the roof. The sidewalls may i nclude at least two side section such as an upper and middle section. The si dewalls may also include a lower side section. The upper and middle sections may be pivotally attached to one another and the middle and lower side sect ion may be pivotally attached to one another so that the upper and middle si dewall sections can be pivoted inwardly towards the bottom platform to provi de a collapsed condition. The sidewalls may also each contain an outer and a n inner surface thereof wherein the outer surface of the upper side wall and the outer surface of the adjacent middle side wall form an angle that is gr eater than 180 degrees when the structure is in an expanded or collapsed con dition. In addition, the inner surface of the middle wall section may overli e the inner surface of the upper wall section in a collapsed condition.
