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 deployment into a long continuous strip or array. Two deployment frames in contact with the stack of panels are rotated to a position perpendicular to the stack. Attached at the outermost ends of each panel hinge are panel rollers. In the accordian folded position, these rollers are alternately located near the top and bottom of the folded stack. The deployment frames each contain an arced raceway for engagement of the upper panel rollers and a straight raceway for engagement of the lower rollers. An upper roller travels down the arced raceway thereby progressively unfolding a pair of hinged panels until they are flat and lie in the deployment plane where they are subsequently extended into the deployed position. For retraction the panels are driven back toward the stack where the upper rollers travel up the arced raceway causing a hinged pair of panels to be refolded together and thereafter be moved into the stack stowage container.
