Abstract: Gas fire devices are provided that produce a swirling flame by passive means using the kinetic energy of gas exiting through burner ports located in a burner and the kinetic energy of air drawn through louvers or flaps radially positioned on the base of a plenum. Situated above the burner and plenum is a chimney, which surrounds the flame and may be a translucent or transparent material to help observers better see the flame.

Abstract: A novel crankcase and umbrella frame for a crank operated umbrella, which illuminates an area about the umbrella, including an umbrella canopy. Crank umbrella frames generally include a support pole, a base, a plurality of pivoting umbrella ribs, and an operating assembly. The operating assembly provides a crank, a crankcase, and a transmission for opening or closing the umbrella ribs. The crankcase of the present invention houses not only a portion of the crank, but at least one integrated luminaire configured so as to be capable of providing light in a desired direction, including toward a supported umbrella canopy to produce a pleasing and diffuse light. Integrating such luminaire in a low profile, convenient, and aesthetically pleasing manner into the crankcase produces a diffuse light without interfering with the operation of the umbrella canopy or activities in the vicinity of the umbrella.
