Abstract (en)
[origin: WO2019171184A1] An anti-seismic device (1 ) is provided for seismically isolating a structure (2) relative to the ground (3) comprising a first support (4) defining a first support plane (4a) integrally connectable to an upper portion and comprising at least two first hinges (40) defining a first constant reciprocal distance (d'), a second support (5) defining a second support plane (5a) comprising at least two second hinges (50) defining a second constant reciprocal distance (d"), a third support (6) defining a third support plane (6a) integrally connectable to a lower portion and comprising at least two third hinges (60) defining a third constant reciprocal distance (d'"), and connection means (7) defining a connection plane (7a) perpendicular to the third support plane (6a) and comprising at least two first rigid bars (70), each defining a first non-deformable direction of connection (70a) and two second rigid bars (71 ), each defining a second non-deformable direction of connection (71 a), wherein the first bars (70) are transiently constrained to a first hinges (40) and a second hinge (50) so that said first directions of connection (70a) of the first bars (70) cross in said connection plane (7a), and wherein the second bars (71 ) are transiently constrained each to a second hinges (50) and a third hinge (60) so that said second directions of connection (71 a) of said second bars (71 ) cross in said connection plane (7a).
