An apparatus for protecting structures, constructions and the like against earthquakes comprises at least a support having a bottom part (6), a top part (8) disposed above the bottom part and horizontally movable in relation thereto, on which the greater part of the structure rests, and a displacement mechanism disposed between the bottom and top parts (6, 8) allowing a controlled relative displacement of the bottom and top parts (6, 8), in such a way, that a relative horizontal displacement of the bottom and top parts (6, 8) causes a vertical displacement of one of said parts, which is counteracted by a resistance device (7). The displacement mechanism comprises a plurality of roller-shaped devices (10, 11), the shape of these devices (10, 11) and/or the top and/or bottom (6, 8) parts being such that a rolling movement of the roller-shaped devices (10, 11) from an intermediate position causes a vertical displacement of the part fitted with the resistance device (7). |
