A canopy structure is provided and includes a framework unit and a flexible covering. The framework unit is formed by a plurality of upright corner members and a plurality of roof support members that are pivotally connected at the top ends of the corner members and, in an erected position, extend upwardly and inwardly to a central apex where they are pivotally connected to one another. The roof support members are formed of extendable sections which preferably telescope with respect to one another so that the framework unit may move into a collapsed state with the corner support and roof support members oriented in closely spaced, parallel relation. Latches are provided to prevent the framework unit from collapsing from the erected position. Constraining and support structure, preferably in the form of scissor assemblies, interconnect adjacent corner support members to prevent them from moving apart past the erect state. The scissor assemblies have one portion pivotally connected to the tops of its associated corner supports and another portion pivotally connected to slide brackets on its associated corner support member. A cantilever member interconnects each roof support member and the slide bracket on its associated corner support member. The central 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 a larger canopy structure.

A canopy structure adapted to be folded and stored in a collapsed state and erected in an expanded state on a support surface, comprising: a canopy framework unit including a plurality of upright corner support members each having a bottom end positionable on the support surface and a top end opposite the bottom end, said corner support members oriented alongside one another in the collapsed state and moveable outwardly apart from one another toward the expanded state, a plurality of roof support members pivotally connected to one another on first pivot axes at first ends thereof to define an apex located centrally of said canopy unit, each said roof support member projecting radially outwardly from said apex to terminate at a second end pivotally connected on a second pivot axis to the top end of a respective corner support member whereby said roof support members and said corner support members form the canopy unit may be folded about said first and second pivot axes into the collapsed state with said roof support members and said corner support members oriented in closely spaced relation to one another, each said roof support member including a pair of extendable sections moveable between a retracted state when said canopy structure is in the collapsed state and an extended state when said canopy structure is in the expanded state, said roof support members sized such that said apex is located above a plane defined by said top ends when the canopy structure is in the expanded state and said roof support members are in the extended state, said roof support members each oriented at an acute angle with respect to said plane, constraining and support means for preventing relative movement of said corner support members outwardly apart from one another past the expanded state and for maintaining lateral stability of the corner support members in the expanded state, and latch means associated with each said roof support member for releaseably retaining the extendable sections of each respective roof support member in the extended state to prevent folding of the canopy structure into the collapsed state and whereby the downward force exerted on said apex exerts an outward force component tending to move said corner support members apart from one another against said constraining means; and a flexible covering sized to extend across the canopy framework unit and be supported by said roof support members to form a top for said canopy structure, said covering having perimeter edge portions extending between the top ends of adjacent ones of said corner support members and a central peak portion exerting a downward force on said apex.
