US Patent 8434196 Multi-axis compliant hinge

Multi-axis compliant hinges used in conjunction with strut elements to form a collapsible structure. The hinges behaves similar to a pin-clevis hinges but have increased compliance during the deployment sequence allowing connected struts to translate and rotate finite amounts relative to each other. Once deployed, the hinges lock out to form strong and stiff joints. The hinge uses two opposing resilient tape spring surfaces for each axis. The opposing tape spring surfaces of each axis are joined together by rigid inserts at their ends opposite the common connection point and to which structural members or struts are connected.
