Abstract: An improved isolator includes a bar of elongated base-forming members adapted to be mounted to a supporting surface and an elongated load-supporting bar adapted to support the load connected to, and supported above, the base-forming bars by a pair of arched flexural supports. Each support is formed of a series of individual flexural elements. The flexural elements are oriented or biased at an acute angle with respect to the horizontal, the first group of elements being biased in an angle opposed to that of the second group. The invention demonstrates more symmetrical response over an equivalent conventional isolator and permits further tuning of isolator response in accordance with load requirements.
