Abstract: A flexure mechanism, the basic elements of which comprise a foundation plate, and a mounting plate which is desirably mounted generally parallel to the foundation plate and which is secured from the foundation plate by a series of flexible support elements, the support elements being secured to the foundation plate in a generally circular configuration and which incline conically, inwardly, into attachment to the mounting plate, also in a generally circular configuration. If the point of convergence of the support elements lies in the plane of the distal surface of the mounting plate, the foundation plate will move, in two degrees of freedom relative to the foundation plate much as if the two plates are pivotally connected to each other. The support elements may be adjustably mounted to the foundation plates and mounting plates, and means may be provided to move the mounting plate relative to the foundation plate.
