Abstract
An air mattress comprising an inflatable and deflatable flexible body enclosing an air chamber having a resilient means urging the opposite upper and lower walls of the body apart while being yieldable to permit the body to be folded and deflated. In one embodiment, removable a closure is attached to the body to be received in a portal in the wall of the body to seal the chamber closed. When the body is unfolded into a generally horizontal or planar position with the portal opened, the resilient means within the body will separate the upper and lower walls of the body drawing air from the atmosphere into the chamber, the portal may then be closed to seal the air in the chamber. The air mattress is illustrated on a foldable bed including frame portions which are foldable into overlying positions to fold and deflate the mattress and which are unfoldable into a horizontal position to unfold and inflate the mattress. In a preferred embodiment, a valve in the portal is actuated to open position to deflate the mattress upon folding of the bed frame and to closed position upon unfolding of the bed frame. A linkage interconnects the valve and the bed frame to actuate the valve in response to folding or unfolding of the bed frame.
