  • Bed with a plurality of vertically aligned body support members which communicate with a common fluid chamber
    Patent number: 5446933
    Abstract: A bed is described which includes a plurality of body support members telescopically received in and protruding vertically from closely spaced vertically aligned body support guides. A fluid chamber underlies the guides. A downward pressure applied to one body support member is transmitted via fluid in the fluid chamber to all body support members. The body support members are telescopically movable relative to the guides in response to fluid pressure. A pressure counterbalance is provided which exerts pressure upon fluid in the fluid chamber to counter pressure exerted upon fluid in the fluid chamber by a body at rest upon the body support members.
