Abstract: A collapsible storage structure for the storage of an object includes a base having front and rear ends and on or over which the object can be placed. The base comprises a pair of longitudinally extending, spaced, parallel rails. A plurality of inverted, substantially U-shaped canopy supports span the base from one rail to the other and are mounted so as to be foldable with respect to the base. A canopy is carried on the canopy supports, the arrangement being such that, when the canopy supports are in a collapsed configuration, the object can be positioned with respect to the base, whereafter the canopy supports can be displaced to an configuration in which the canopy covers the object. A transport mechanism comprises a pair of carriages. One carriage is slidably arranged on each rail, the carriages carrying at least certain of the canopy supports and being displaceable between a first position in which the canopy supports are collapsed and a second position in which the canopy supports are erected.
