Document Type and Number:
WIPO Patent Application WO/2017/033707
Kind Code:
A1
Abstract:
A vertical seismic isolation device, with which a movable frame on which an object for seismic isolation is loaded can smoothly move vertically and which is small, lightweight and easy to handle, is provided with: a fixed frame (2); a movable frame (3) disposed above said fixed frame; a support-guiding mechanism (4) for allowing only vertical movement of said movable frame; and a restoring member (5) for keeping a constant spacing between the movable frame (3) and the fixed frame (2). Said support-guiding mechanism (4) is provided with: a track rail (40) laid on the fixed frame (2); a moving block (41) installed on said track rail via multiple rolling elements; a support leg (42), one end of which is connected to the moving block, the other end of which is connected to said movable frame (3) and which converts the vertical movement of the movable frame to movement of the moving block (40); and an auxiliary leg (43), which is set to a length that is half that of the support leg (42), one end of which is connected to an intermediate position of the support leg (42) in the longitudinal direction and the other end of which is connected to the fixed frame (2).
