Abstract
Abstract A structure to reduce vibration consists of a rigid bottom plate and a rigid top plate which may act as a vibration reducing platform. The plates are kept separated, in one embodiment, by a large number of fluid-filled separate containers having thin flexible walls. Preferably the containers are spheres held in a web and filled with air at above atmospheric pressure. In another embodiment the plates are separated by an elongated fluid-filled tube which forms a substantially closed curve in plan view.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
113 words
A vibration isolating device consisting of a first panel intended to be positioned on a supporting structure, a second panel adapted to be the platform to support a device to be vibration isolated, and a plurality of at least three fluidfilled containers in one plane positioned between said panels and separating said panels from each other, each container having its wall of flexible sheet material, wherein at least one of said panels has fluid passages leading to its ports at its internal surface, the containers are formed by fixing a film to said panel to form a fluid-tight seal and leaving the film free from the panel at the location of said ports.
Claim 2
Dependent Claim
