Abstract:
A self inflated air cushioned bed comprising:a base having a first adhesion element attached to a top face of the base; multiple air units each provided with at least two air cells securely mounted on top of a substrate that has a second adhesion element attached to a bottom face of the substrate to correspond to the first adhesion element so that the air units are removably mounted on top of the base; at least one unidirectional valve mounted on the substrate to allow air to flow into the at least two air cells, the substrate having a seat formed on top of the substrate and having an air path defined through the substrate and the seat to receive therein the unidirectional valve and a mounting recess, the at least one unidirectional valve having a flange formed to correspond to the mounting recess so that the at least one unidirectional valve is mounted in the seat with the flange received in the corresponding mounting recess; and an expanding device received in each one of the at least two air cells in each of the multiple air units to maintain the at least two air cells in each of the air units to be expanded, whereby when the at least two air cells of each of the air units are expanded due to the expanding device, the at least one unidirectional valve allows air to flow into the at least two air cells of each of the air units so that the air units are maintained inflated.
