  • Patent number: 4558476
    Abstract: A flotation type apparatus used to support loads is disclosed, as well as a method for supporting a load with a flotation apparatus. The basic configuration of the apparatus is comprised of three major components, namely, a fluid filled envelope, a resilient material within said envelope, and a gas chamber located below the resilient material and within said envelope. One or more loads are placed upon the upper surface of the fluid filled envelope and are supported by a combination of the forces exerted by the liquid, the resilient material and the gas. The pressures of the liquid and gas may both be varied to alter the supportive force experienced at the surface of the apparatus. The gas chamber may be divided into a plurality of chambers, the pressure in each being individually adjustable to vary the supportive forces felt over the surface of the flotation apparatus.
