A quickly erectable structure includes expandable/collapsible top and bottom assemblies that are interconnected to facilitate forming an enclosure and to facilitate taking down the enclosure. Specifically, the bottom assembly includes a plurality of interconnected X-shaped subframes that combine to form a telescoping scissor frame. The top assembly includes a plurality of inverted foldable Y-shaped subframes attached together and to a top of the telescoping scissor frame in a manner that combines the two to form a stable umbrella-like overcenter top frame attached atop the telescoping scissor frame. A drawstring mechanism is attached to a peak of the structure to hold the top frame in an expanded position. Flexible covers are attached to the two frames, and a drawstring arrangement on the top cover allows flaps to be lifted to form 360 degrees of windows.

1. A quickly erectable structure comprising:an expandable/collapsible top apparatus having a top internal frame and a flexible top cover attached to and supported by the top internal frame for movement between an expanded position and a collapsed position, the top internal frame including rigid top frame members pivotally attached together to define a peak where the top frame members extend radially from the peak, the top internal frame further including rigid right/lower and left/lower frame members pivotally attached to a bottom of each one of the top frame members at an overcenter joint, the right/lower and left/lower frame members forming an inverted “Y” shape with the associated top frame member when in the expanded position but forming a dense stack of substantially parallel frame members when in the collapsed position, a lower end of each right/lower frame member being pivotally attached to a lower end of the next adjacent one of the left/lower frame members so that, when expanded, the right/lower and left/lower frame members form a zigzag pattern around and spaced from the peak; a releasable support structure attached to the peak and each of the top frame members for selectively holding the top apparatus in the expanded position; and an expandable/collapsible bottom apparatus having a bottom internal frame supporting the top apparatus, and including a flexible bottom cover supported by the bottom internal frame, the bottom apparatus being expandable to form a geometric shape having sides and being collapsible for compact storage, wherein the bottom internal frame includes a crisscrossing pattern of pivotally interconnected pairs of frame members that form repeating “X” shapes. 2. The structure defined in claim 1, wherein the top internal frame is positioned completely within the bottom internal frame when in the collapsed position.3. The structure defined in claim 1, wherein the top and bottom apparatus are interconnected and characteristically do not include loose pieces.4. The structure defined in claim 1, wherein the top apparatus forms a roof that is dome-shaped and outwardly concave, such that the top apparatus simulates an umbrella shape.5. The structure defined in claim 1, wherein the top and bottom apparatus have a total height and size comparable to a golf bag when collapsed, such that the structure is adapted to be easily stored in a vehicle trunk.6. The structure defined in claim 1, wherein the jointed frame members of the top apparatus include an intermediate joint that moves overcenter when the top frame is moved between the collapsed and expanded positions.7. The structure defined in claim 1, wherein the bottom internal frame, when expanded, forms a free-standing, self-supporting structure that is stable, even when positioned on uneven ground.8. An erectable structure comprising:an expandable/collapsible bottom apparatus having a bottom internal frame and a flexible bottom cover supported by the bottom internal frame, the bottom apparatus being expandable to form a geometric shape having sides and being collapsible for compact storage; and an expandable/collapsible top apparatus having a top internal frame and a flexible top cover supported by the top internal frame, the top internal frame having a plurality of radially-extending jointed frame members arranged in an umbrella-simulating arrangement, the jointed frame members being integrally attached to and supported by the bottom internal frame and having joints movable overcenter to an expanded position to form a roof over the geometric shape and movable to a collapsed position in the bottom internal frame for compact storage as a unit with the bottom apparatus, wherein the bottom internal frame includes bottom frame members and further includes a stake pivotally attached to one of the bottom frame members and the bottom cover, the stakes being movable between a use position oriented toward a ground surface and a storage position oriented away from the ground surface, and including a holder for holding the stakes in the storage position.
