Hinge assembly for supporting a fan on a roof

Abstract

A buttressed hinge assembly adjusts to fit a roof in order to hold a fan thereon, which fan is especially suitable for a restaurant roof. The hinge assembly attaches to a roof vent to hold the fan in a proper position, yet permits the fan to be easily moved for cleaning of vent and the fan.
