Claim 7

In combination, a foundation, an upstanding perimeter wall structure enclosing an interior area of generally regular plan shape within the confines of said perimeter wall structure and with the latter supported from said foundation, a central upstanding roof support column supported at its lower end from said foundation centrally of said interior area, at least an upper portion of said column being hollow, a support structure encircling and supported from an upper portion of said column at a level spaced above the upper portions of said perimeter wall structure and including mounting portions spaced about and outwardly from said column, a roof structure bridging the upper marginal portion of said perimeter wall structure and closely embracing said upper portion of said column to thereby close said interior area from above, said roof structure including downwardly and outwardly inclined roof rafter members spaced about and generally radiating outwardly from said column with their upper inner ends supported from said mounting portions and their lower outer ends supported from upper portions of said perimeter wall structure, outer roof panels secured over said rafters, said roof structure defining an upper central void area defined by upper marginal portions of said roof structure spaced outwardly from and extending about the upper end of said column, a cap structure supported from said upper marginal portions of said roof structure and the upper portion of said column forming a weather closure over said roof structure upper marginal portions and substantially sealed relative thereto, said hollow upper end portion opening upwardly through said cap structure, a space heater structure supported in a lower portion of said interior area adjacent the center portion thereof, said heater structure including a flue duct opening into the interior of said hollow portion of said column below said roof structure, means establishing a seal against air flow from within said interior area below said roof structure outwardly through said central void area, said roof structure defining the vaulted ceiling from said interior area, said interior area being substantially completely open, in vertical directions, from said foundation to said vaulted ceiling, for vertical air flow currents therein, whereby rising convection air currents of heated air may be generated in the central portion of said interior area by said space heater and the hollow portion of said column upwardly through which heated flue gases from said heater are vented and the convection air currents may thereafter move downwardly along the inner surfaces of said vaulted ceiling and perimeter wall structure and thereafter inwardly over said foundation toward said central portion, at least portions of the outer periphery of said central area being partitioned through the utilization of upstanding partitions supported from said foundation and extending inwardly from spaced portions of said perimeter wall structure toward said column, said partitions terminating upwardly, along at least major length portions of the upper marginal edges thereof, below said roof structure and the portions of said interior area defined between adjacent partitions being open from said foundation to said ceiling.
