ABSTRACT:
A self-supporting umbrella canopy has a high strength-to-weight ratio and the ability to compactly fold flat. The umbrella canopy uses a series of collapsible, closed cross-section cells to provide its support and to provide weather protection for a person or persons below. The closed cross-section cells are attached to each other in series so that the umbrella canopy may conveniently unfurl in a radial manner. Construction of the umbrella canopy lends itself to automated processes. Due to the self-supporting nature of the collapsible, closed cross-section cells, lightweight and inexpensive waterproof materials may be used to construct the umbrella canopy.
