ABSTRACT:
A collapsible structure comprising a close fitting cover which substantially encapsulates a light weight superstructure made up of a pair of U shaped, generally vertically extending members having ground engaging legs and a pair of U shaped generally horizontally extending members pivotally interconnected with the vertically extending members at locations elevated with respect to the ground. Certain of the pivotally interconnected members are constructed of different sizes and are freely pivoted relative to one another so that the structure can be collapsed into a highly compact configuration wherein the structural members nest within one another.
