A portable canopy structure may be erected from a collapsed state to an expanded state that shelters a desired surface. The canopy structure includes a dome-like covering that is held in position by a support framework having a plurality of upright support members that are interconnected by a plurality of scissor assemblies. Each upright support member slideably mounts a slide bracket, and a rigid bracket is mounted at its top. The scissor assemblies are connected to these brackets. Preferably the structure is in the form of a parallelepiped, and an internal scissor assembly extends between two facing side scissor assemblies which interconnect the upright supports. The covering extends across the tops of the supports and has side panels which depend downwardly from its perimeter, and the internal scissor assembly supports a central post that helps support the covering. A screen may be positioned around the support structure and may be connected to and be downwardly dependent from the side panels. Guy cords may be provided for the upright support members.

A collapsible canopy shelter adapted to be positioned on the ground, comprising: a plurality of upright corner support members each having a top and bottom and oriented to define vertical edges of a selected geometric configuration; a slide bracket slideably mounted on each of said corner support members and moveable therealong; an edge scissor assembly interconnecting adjacent ones of said corner support members, each respective edge scissor assembly oriented in a generally vertical plane and having one portion pivotally secured to the top of its associated corner support members and another portion pivotally secured to the slide bracket of its associated corner support members, said edge scissor assemblies operative to expand and contract whereby its associated corner support members are caused to move away from and toward one another to vary the dimensions of said geometric configuraiton, said canopy shelter being in an expanded position when said corner support members are moved away from one another and in a collapsed position when said corner support members are moved toward one another; an internal scissor assembly extending across said geometric configuration and connected between at least two of said edge assemblies and operative to expand and contract in response to expansion and contraction of said edge sicssor assemblies; first releasable latch means on each said corner support members for releasably retaining its respective slide bracket adjacent the top of its respective corner support member to retain said canopy shelter in the expanded position; a flexible covering extending across the tops of said corner support members and sized to cover the upper surface of said geometric configuration when said canopy shelter is in the expanded position, said covering including a top panel extending across said upper surface and side panels connected to said top panel and extending downwardly alongside surfaces of said geometric configuration; means along the lower edge of said side panels for releaseably securing said side panels to said corner support members; and an upright interior post secured to the internal scissor assembly and operative to positively support a central portion of said flexible covering when said canopy shelter is in the expanded position.
