System for the modification of the rigidity and damping properties of structural joints

A system for the modification of the rigidity and damping properties of structural joints, said system comprising

• at least an intermediate coupling structure (3) adapted receive, at both sides thereof, the application of two structures (1, 2) to be coupled;
• first and second releasable blocking means (6) adapted to immobilize, in a mutual coupling relation, a first of said structures (1, 2) with a first part of said intermediate structure (3) and the second of said two structures to be coupled with a second opposite part of said intermediate structure;
• a set of first extended bistable components (7), with a first feature of structural resistance, spaced around an internal periphery of said intermediate coupling structure and adapted to be fixed at one of their ends to an inner face of said first structure (1) to be coupled and, at the other end, are secured to an inner face of said intermediate coupling structure (3), each one of said first bistable components (7) being in a partially bent condition when said first structure is blocked with respect to said intermediate structure due to the action of said first releasable blocking means (6);
• a set of second extended bistable components (8), with a second feature of structural resistance greater than that of said first bistable components (7), spaced around the internal periphery of said intermediate coupling structure and adapted to be fixed at one of their ends to the inner face of said first structure (1) to be coupled and at the other end adapted to be fixed to an inner face of said second structure (2), each one of said second bistable components (8) being in a partially bent condition when said first structure (1) is blocked in a coupling relation with said second structure (2) through said intermediate structure (3) and by the action of said first and second releasable blocking means (8), whereby a series of reference structural features, are defined.
