Abstract: Anti-seismic device for seismically isolating structure relative to ground including first support defining first support plane integrally connectable to upper portion and including two first hinges defining first constant reciprocal distance, second support defining second support plane including two second hinges defining second constant reciprocal distance, third support defining third support plane integrally connectable to lower portion and including two third hinges defining third constant reciprocal distance, and connector defining connection plane perpendicular to third support plane and including at least two first rigid bars, each defining a first non-deformable connection direction and two second rigid bars, each defining a second non-deformable connection direction. First bars transiently constrained to first hinges and second hinge so the first connection directions of first bars cross in the connection plane.

Abstract: Provided is an inertial platform including an upper support that can be integrally attached to a mobile element and defines an upper plane, a base support that can be fixed to the ground and defines a base plane, at least one intermediate support arranged between the base and upper supports, articulated quadrilaterals each including two lower hinges, connected to one of the base or intermediate supports, two upper hinges, connected to one of the intermediate or upper supports, two rods which connect the lower hinges to the upper hinges in a crossed manner, and motor means configured to move the articulated quadrilateral internally according to its single degree of freedom defining an axis of rotation, and each including sensing means to detect the position of the upper plane with respect to the gravitational gradient functionally connected to means of control of the platform and at least to the motor means.
