摘要：A canopy structure is provided and includes a framework unit and a flexiblecovering. The framework unit is formed by a plurality of upright corner members and aplurality of roof support members that are pivotally connected at the top ends of thecorner members and, in an erected position, extend upwardly and inwardly to a centralapex where they are pivotally connected to one another. The roof support members areformed of extendable sections which preferably telescope with respect to one anotherso that the framework unit may move into a collapsed state with the corner support androof support members oriented in closely spaced, parallel relation. Latches are providedto prevent the framework unit from collapsing from the erected position. Constrainingand support structure, preferably in the form of scissor assemblies, interconnect adjacentcorner support members to prevent them from moving apart past the erect state. Thescissor assemblies have one portion pivotally connected to the tops of its associatedcorner supports and another portion pivotally connected to slide brackets on itsassociated corner support member. A cantilever member interconnects each roofsupport member and the slide bracket on its associated corner support member. Thecentral apex may include a spring biased central post to support the peak of the covering

placed on the framework unit. Several framework units may be formed together into alarger canopy structure.
