Abstract
In one embodiment, a shelter includes a first hub configured to be moveably coupled to a plurality of support linkages. The shelter excludes a second hub different than the first hub. The shelter includes a support linkage from the plurality of support linkages. The support linkage is pivotally coupled to the first hub. The support linkage is moveable between a collapsed configuration and an expanded configuration. The support linkage includes a first member and a second member pivotally coupled to the first member. An angle formed by an intersection between a longitudinal axis defined by the first member and a longitudinal axis defined by the second member is less than 180 degrees when the support linkage is in its collapsed configuration. The angle is greater than 180 degrees when the support linkage is in its expanded configuration.
