ABSTRACT:
A mechanism for deploying and retracting an isogrid structure particularly suited for use in supporting low weight reflective or absorbtive surfaces, characterized by a plurality of hinged isogrid panels stowed in an accordian folded stack arranged for automatic deployment into a long continuous strip or array. Two deployment arms in contact with the stack of panels are rotated to a position perpendicular to the stack, carrying with them the first panels. Thereafter the panels are extended by powered sprockets which engage the panel edges. A shutter bar sequentially releases pairs of panels during deployment. For retraction, the sprockets drive the panels back toward the stack where a creaser bar hinges pairs of panels which are thereafter folded into a stack by means of the shutter bar capturing and stowing each folded pair of panels.
