Abstract: An earthquake-proof plinth includes a display floor plate that has an aperture configured to fit a 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; 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.

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.

Abstract: A pedestal capable of quickly, safely, and securely protecting an exhibited ornament and effectively preventing the ornament from being overturned, dropped, or damaged. The pedestal is constituted so as to open a pair of openable shutter plates (6) and (7) by using a support stand (1) whose top and bottom are provided with a pair of openings (5) and (11) so that they are faced to each other, setting the two openable shutter plates (6) and (7) to the top-side opening (5) of the support stand (1) so that they can be closed while butting them each other at the central portion of the opening (5), suspending the upper-end opening margin (12a) of a bag (12) having a cushioning performance to catch the ornament from the lower portion of the bottom-side opening (11), the pedestal further including a drive (20) for the shutter plates and a vibration sensor (22) and operating the drive (20) when the vibration sensor (22) detects vibrations due to an earthquake.
