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