ABSTRACT:
A collapsible tent including a closed loop resilient coilable member, the member being distorted to form at least three support loops. Each support loop adjoins the other support loops along a single portion of its perimeter with the support loops having a common adjoining region. Each support loop has a perimeter substantially the same as that of the other support loops and a membrane attached to the perimeter of the support loop. The membrane extends between the opposing portions of the support loop to restrain the support loop. The tent further includes a base membrane attached to the perimeters of the support loops and extending between the support loops to restrain the support loops in relation to one another. When the tent is expanded, the support loops are in spaced relation to one another around the common adjoining region and are restrained by the membranes. The common adjoining region forms an apex of the tent and the membranes define walls and a base of the tent. When the tent is fully collapsed, the support loops form overlapping loops over one another that are coiled.
