Abstract
A self-inflating structure consists essentially of a block of open-cell, resiliently compressible, foam material which has been shaped to a desired form and covered with an airtight envelope having a sealable aperture. The structure can be pressed to expel any air or other fluid out of the foam material and any internal void through the aperture. The structure is kept pressed or the aperture is sealed in order to keep it in its collapsed state. Upon release of the pressing form or the opening of the aperture, the block of foam bounces back to its original state sucking in ambient air and restoring the structure to its full size. The method for shaping the foam block includes extruding, machining, and carving with patterned sets of blades or burning wires.
