Abstract: The present invention provided an air hose that is configured to be used in conjunction with an air compressor. The air hose includes a tube portion having open proximal and distal ends. The tube portion includes a flat upper portion and lower portion connected at their ends to a pair of rounded shoulders that give the tube portion a substantially rectangular cross section in a collapsed state. The hose further includes radial plies that extend within the cross section across the upper, lower portions, and around the rounded shoulders. The radial plies bias the upper and lower portions together into a collapsed state, wherein the upper and lower portions are parallel and substantially in contact with one another. The upper and lower portions expand from a collapsed state to an expanded state when compressed air is forced therethrough giving the tube portion a substantially rounded cross section.

Abstract: A pneumatic air hose is formed from an inner elastic tubular member surrounded by an outer inelastic tubular member. In use, one end of the air hose is connected to an air compressor and the end to a pneumatic tool. When engaged, the pneumatic air hose and inner elastic tubular member expand to an extended state while the outer tubular sleeve is extended along with the inner tubular member to a length greater than the original non-extended state. Upon disengagement of the air compressor, the expandable hose resumes its original non-extended state.
