Abstract
A frame is articulable between erected and a collapsed states and includes first and second frame supports. Each frame support has a pair of center frame members rotatably coupled about a center joint, each of which is selectively moveable between a first position when the frame is in the erected state and a second position when the frame is in the collapsed state. A purlin assembly has first and second purlin members that are rotatably coupled about a purlin mid-joint. A first end of the purlin assembly is pivotally coupled to the first frame support, and a second end of the purlin assembly is pivotally coupled to the second frame support. The purlin assembly is selectively lockable in an extended position when the frame is in the erected state and is rotatable to a folded position when the frame is in the collapsed state.
