Collapsible frame structure

摘要

A collapsible frame structure has an upper frame section connected to a base frame section by a plurality of hinged struts. Both the upper frame and the base frame section comprise a pair of opposed rigid frame members pivotally connected by opposed hinged frame members. The hinged members fold inward of each section to collapse the section and extend outward to expand the section. The hinged struts fold inward of the structure to raise and lower the upper section relative to the base section. A pair of winches mounted to the base frame section and operatively connected to the struts extend the struts to raise the upper frame section above the base frame section to an operative frame position. Stabilizing members are mounted to an upper portion of the struts to balance the weight of the upper section upon the struts, thus enabling the struts to extend.
