ABSTRACT:
A floor isolation system includes a platform and a multidirectional spring unit. The platform has rolling supports that isolate the platform from lateral movements of a substrate. The platform further has sliding supports that (1) prevent the platform from moving freely during daily service and (2) dampen lateral movements of the platform caused by the lateral movements of the substrate. The multidirectional spring unit links the substrate and the platform to provide a spring force in any horizontal direction that limits the lateral displacements of the platform. The multidirectional spring unit includes a spring secured to the substrate, a fairlead, and a cable having one end secured to the spring and another end passing through the fairlead and secured to the platform.
