ABSTRACT:
A convertible roof (20) moves between extended and retracted positions for selectively covering an area, or exposing the area to ambient weather conditions. The roof (20) includes a first panel (26) having a plurality of inflatable tubes (28). One end of each tube connects to one side of the base of the roof and the other end connects to the other side of the roof's base. An air compressor (42) inflates the tubes sequentially via valves (40) and air duct anchor posts (30) or (112) for causing the first panel to move by inflation air pressure. The inflation air pressure causes the first panel to move from a position extending along one end of the base when the tubes are evacuated, to a second position above the base when the tubes inflate for covering the base. The roof will usually, but not necessarily, include a second panel (26) substantially identical to the first panel. The second panel connects to the end of the base of the roof opposite the end the first panel connects to. An air compressor also inflates the tubes of the second panel and causes the second panel to move by inflation air pressure in substantially the same way as the first panel.
