Abstract: An articulating frame for a shelter includes a plurality of struts pivotally connected to each other to define a skeletal structure that is adapted to be articulated between a folded condition and an erected condition. The skeletal structure in the erected condition includes a segmented arch that defines an interior space. The skeletal structure is adapted to support an associated outer shell covering. The frame includes at least one double-scissor linkage segment including four of the plurality of struts. The four struts include: (i) first and second struts each with opposite inner and outer ends, the first and second struts bring pivotally connected to each other at a first pivot point located between their respective inner and outer ends; and, (ii) third and fourth struts each with opposite inner and outer ends, the third and fourth struts being pivotally connected to each other at a second pivot point located between their respective inner and outer ends.
