Abstract: A manufacture called “earthquake buffer” to protect a building structure from destructive earthquakes as well as to secure its stability under strong winds, comprising two non-resonant rolling friction slide layers positioned above each other on a building footing and consisting of a plurality of cylindrical rollers stretched parallel in a direction of one of the main building axes while being orthogonal to the bars in an alternative slide layer. The slide layers are interlaid with a distributive plate and topped with an inertia block connected to a rigid first floor diaphragm and the building superstructure. With a magnitude of earth movement exceeding a certain threshold, the earthquake buffer permits practically unlimited horizontal excursions of the footing relative to the superstructure while transmitting a dramatically reduced shearing force upwards and preventing any sizable lateral resonant effects in the protected building.

Abstract: A manufacture to protect a structure from destructive earthquakes as well as to secure its stability under the strongest possible wind, having a number of ball transfer units rigidly coupled to a supported superstructure; the same number of pedestal plates supporting the ball transfer units, each having an upper surface having a plurality of curved surfaces with a central depression following the shape of the ball. The force of gravity will keep the structure in its steady initial position when the balls are inset into corresponding depressions at any wind pressure and at slight earthquakes. With magnitude of earth movement exceeding a certain threshold the balls get out of central depressions thus providing a controlled separation of the superstructure from the foundation, and the upper surfaces of pedestal plates with properly designed geometry governs transfer of horizontal movement into the superstructure and prevents hazardous structural vibrations.

Abstract: A manufacture to isolate a structure from earthquake motion of a hazardous magnitude and at the same time to secure its stability under strongest possible wind, which comprises:(a) a number of ball transfer units rigidly coupled to a supported superstructure;(b) the same number of pedestal plates, each having a concave upper surface with an extra central depression following the shape of the ball.The force of gravity will keep the structure in its steady initial position when the balls are inset into corresponding depressions at any wind pressure and at slight earthquakes. With magnitude of earth movement exceeding a certain threshold the balls get out of central depressions, any transfer of horizontal movement to the superstructure dramatically decreases, and hazardous shaking of the earth cannot damage the structure.

Abstract: A manufacture for sheltering people in a case of earthquake emergency using an existing bed. The shelter is designed to protect people on the bed from collapsing structural and nonstructural elements of the building. The shelter has a horizontal frame of shelves for placing the bed on, confiners for fixing the bed, a cover on supports, and a base isolating system of ball-bearing footholds on pedestal plates with concave upper surfaces of proper curvature. Due to properly selected materials, shapes and cross-sections of its elements the shelter provides its own strength under the falling debris, and as a result secures people on the bed, while the base isolating system eliminates horizontal shaking of the shelter and thus prevents people on the bed from being thrown out of protective cover.
