ABSTRACT:
A structure such as a doghouse can be constructed so as to be capable of being folded between an expanded configuration in which parallel side walls are connected by a top, a bottom, and parallel ends and a folded configuration in which the side walls are adjacent to one another. In order to achieve a folding action the top, the bottom and the ends each consists of a set of two parts. The parts of each of these sets extend between the side walls. A first group of hinges are used to pivotally connect the parts of each of the sets to the side walls. A second group of hinges are employed to connect the parts of each set midway between the side walls. All of the hinges of both groups which are secured to the top and the bottom have parallel axes and all of the hinges of both groups secured to the ends have parallel axes. Further, all of the axes of the hinges of the second group are located in a common plane midway between the side walls. In the disclosed preferred structure doors which close through the action of gravity are located on the parts of one of the ends.
