Abstract
Present embodiments provide a roof fan assembly with numerous improvements. The roof fan assembly includes a cover which allows for a fan shroud to be opened. The structure includes a base clamp which connects to the roof of an RV. The base clamp includes a fan and motor which push or pull air out from the RV or into the RV. The base clamp includes a worm gear assembly which includes a worm gear structure to open and close the shroud. The arm may include a sleeve which moves relative to the arm and connects to the shroud at the opposite end. The base clamp includes mounts for connecting the base clamp to the roof as well as allowing for connection of the cover to the fan assembly as a whole. Still further, the structure provides integrated hinges in the base clamp to allow connection of the shroud to the base clamp for pivotal movement.
