ABSTRACT:
A foldable shade structure is presented. The structure is disposed around a rectangular center to which are coupled U-cross section inner and outer bases. Each of the four outer ends is hingedly coupled to a leg which comprises a leg base coupled to the outer base and at least one leg segment is smaller than the leg segment or leg base beneath it in the extended mode and fits into it in the folded mold. The leg then rotates 270.degree. to fit into the outer base which rotates 180.degree. to fit into the inner base and each of the four inner bases is folded together forming a rectangular center portion into which the shade can be folded and retained. A cord can then hold the composite together and can be coupled to a handle for carrying purposes.
