    摘要: A low-bed type seismic isolator for a display case, which includes: at least two lines of arcuate X-rails (3) fixed to a lower plate (1) on a foundation and having lower central portions and higher end portions; at least two lines of arcuate Y-rails (4) fixed to a lower surface of an upper plate (2) above the X-rails (3) and having higher central portions and lower end portions in a direction perpendicularly to the X-rails; connection blocks (5) having lower portions clamping the X-rails, upper portions clamping the Y-rails, and a disk spring provided at the central portions thereof; absorbers (8) disposed on the ends of the X-rails and Y-rails and recesses which fixedly accommodates support legs (7) fixed to the lower surface of the upper plate and protruded downwardly from a seismic isolation object. The seismic isolator does not substantially change the height of a seismic isolation object, and can be applied, for instance, to a display case of a museum, so as to provide the effective seismic isolation as well as to facilitate an inspection to a displayed exhibit The additional provision of casters makes it possible to readily move the seismic isolator to any arbitrary place.
