ABSTRACT:
A pad for providing liquid support on inclined surfaces includes a membrane envelope having two large parallel faces a plurality of collapsible perforated ribs, horizontally oriented within the envelope securing the parallel relationship of the faces, and a plurality of sponge-like bars received between adjacent ribs within the envelope each bar having an uncompressed volume slightly greater than that defined between adjacent ribs and the faces. A liquid fills the capillary or wicking structure of the sponge-like bars within the envelope. The combination of the sponge-like bars, the flexible ribs and atmospheric pressure maintain a hexahedral configuration of the liquid filled pad on an inclined surface.
