COLLAPSIBLE SUPPORT STRUCTURE

摘要

A collapsible structure for supporting a surface comprises legs with connecting members therebetween and means for allowing the structure to be transformed between erected and collapsed configurations such that the largest external horizontal dimension of the structure in the collapsed configuration does not exceed the largest external horizontal dimension of the structure in the erected configuration. The transforming means comprises two folding members disposed on opposite sides of the structure. Each folding member is pivoted adjacent the central region thereof and each end of each folding member is pivotably mounted adjacent a corresponding leg of the structure. One or both folding members is provided with a cover member adapted to cover the central pivot region when the structure is in the erected position thereby reinforcing the central pivot joint.
