ABSTRACT:
The flexible pivot includes a plurality of pairs of crossed flexible strips, each pair anchored in a pair of blocks at an angle to each other. The strips are displaced from each other edgewise and if they engage at all, engage at centers of their edges which do not move. The strips extend, and are capable of flexing, between the blocks. The intersections of the planes defined by the pairs of strips when unflexed, define a common line which is the axis of the flexible pivot. One of the blocks of each pair is secured firmly to a rigid support and the other block of each pair to a member which is pivoted. The strips are limited to flexing over a very small angle but the member which is pivoted may be mounted remotely from the axis so that the displacement of this member is amplified and is substantial.
