Abstract:
1. A selectively collapsible structure comprising: a base; a first side wall rotatably attached to the base, and having angular movement relative to the base between collapsed and erected configurations; a second side wall rotatably attached to the base, and having angular movement relative to the base between collapsed and erected configurations, the first and second side walls having angular movements independent of each other relative to the base; a roof guidingly coupled to both the first side wall and the second side wall and having movement relative to the base guided by angular movement of the first and second side walls between their collapsed and erected configurations; a biasing assembly urging the structure into a fully erected configuration, the biasing assembly having first and second states in which it has relatively greater and lesser amounts of stored energy, respectively, the first and second side walls urged from their collapsed configurations toward their erected configurations by transition of the biasing mechanism from its first state toward its second state; and a standoff assembly having at least two support members, each support member being defined by first and second ends and having a base cap attached to the second end, wherein the base cap further comprises an opening that is sized to matingly receive the first end of a separate support member of a second standoff assembly when the collapsible structure is in a storage configuration.
