摘要： A patio umbrella that includes a dining table and a fuel-burning radiant heater avoids overheating of the upper canopy by mounting the support on which the upper canopy rests in the shadow cast by a reflector that converges upwardly to a chimney portion. The reflector is affixed to the housing of the combustion chamber. In addition to reflecting radiant heat downwardly onto the table and the diners, the reflector shields the upper canopy support from radiant heat and provides a duct for venting the products of combustion. As the latter pass up through the chimney portion, cooler air is drawn up through the space between the reflector and the upper canopy support thereby preventing hot air from stagnating there. The upper canopy support is mounted to the reflector and spaced above it by a number of insulative ceramic spacers. Brackets affixed to the reflector extend outwardly of the pivotal attachment of the ribs of the umbrella, thereby permitting the ribs to clear the combustion chamber and at the same time shortening the ribs so that when the umbrella is closed the lower ends of the ribs are well above the table top so as not to intrude into the space used for serving food. A safety switch, mounted within the column that supports the heater, extinguishes the heater as the umbrella is closed.
