摘要： A linkage (160, 300) for constraining the motion of a reference member (162, 302) along a reference axis (164, 306) with a substantial degree of motion along this axis while exhibiting good resistance to side forces and moments as well as off-axis motions. In one form the linkage includes two pairs of flexure elements (168, 170 and 172, 174), each flexure element having a vertex end portion and at least one distal end portion. The flexure elements of each pair are connected so that their corresponding pairs of distal end portions are coupled to each other. Each of the coupled distal end portions is connected by a rigid link (176, 178) to the corresponding pair of connected distal end portions of the other pair of flexure elements so that the junction of the distal end portions of each coupled pair are separated by a predetermined distance in the direction of the reference axis. The vertex portions of corresponding ones of the flexure elements of each pair is connected to the reference member (162). The two vertex portions coupled to the reference member (162) are separated by the predetermined distance in the direction of the reference axis (164). The vertex portions of the other flexure elements are connected to the support member at points separated by the predetermined distance in the direction of the reference axis (164).
