Earthquake-proof plinth to protect an object thereon

Abstract

The present invention is directed to an earthquake-proof plinth having a trapdoor mechanism that can drop an article on a seat right down while keeping the seat horizontal as it originally is, and then, stop the article in the course of dropping by means of a shock-absorbing means, so that the article even with a protrusion(s) can be, as a whole, protected from an impact as it is dropped. The plinth is comprised of a display floor plate that has an aperture dimensioned and shaped to fit a vertically middle section of an article seated on the plinth and that has a seat panel passing through the aperture and supported by a shaft extending vertically downward from the seat panel; a vibration sensor detecting vibrations; a shaft stopper that stops the seat panel and shaft in a shock-absorbing elastic fashion when the article still on the seat panel falls and eventually has its middle section fitted in the aperture of the floor plate; and a retainer that normally retains the shaft in position to keep the seat panel flush with the display floor plate while it releases the shaft in response to a detection signal from the vibration sensor to let the seat panel and shaft drop.
