ABSTRACT:
A collapsible, or deployable, truss unit to be combined with a multiplicity of other similar units in an array for the construction of, for example, medium to large size frameworks in outer space. Each truss unit comprises two substantially rectangular arrangements of four rigid side members pivotally joined to one another, to be directed toward the opposite sides of the framework constructed, and four rigid cross members extending between the joints of the two rectangular arrangements of the side members. A flexible brace or braces are arranged diagonally of each rectangular arrangement of the side members. Two diagonally opposite ones of the four cross members have each a hinge assembly mounted thereto for longitudinal displacement. Each movable hinge assembly has two rigid diagonal members pivoted thereto each at one end, the other ends of the diagonal members being pivoted to two diagonally opposite ones of the four joints of one rectangular arrangement of side members. So constructed, the truss units can be each compactly held together during transportion and can be readily deployed into cubic or like shape in place of assemblage.
