Abstract
An extendible structure that can be collapsed to a shorter length and extended to a longer length. A pair of station members are interconnected by at least three longeron members. Each longeron member has two longeron elements that are pivoted together so they can fold toward one another or aligned to form a column. Each element is pivoted to a respective station member. Stays rigidify the structure when extended, and are opposed by buckling springs (Euler columns) that exert an outward resultant force on each longeron member at its folding point.
