Abstract
A suspension system for isolating a platform from external vibrations includes spring assemblies suspending the platform. In each spring assembly an elongated outer coil spring is suspended at an upper end thereof from a support structure. A tube is disposed loosely within the outer spring and is attached to a lower end of the spring so as to extend upwardly. An elongated inner coil spring is disposed loosely within the tube and is suspended from an upper point of the tube. The inner spring has a lower end attached to the platform. For friction dampening, o-rings are fitted on the inner spring in sliding contact with the tube.
