Abstract
A vent apparatus () comprises a perforated screen (), a door (), a guide (), and a handle (), and a lever assembly (). The door is adjacent a first face () of the screen and includes at least one arm () that extends through at least one slot in the screen. The guide () is mounted adjacent a second face () of the screen. The handle () is in pivoting connection with the at least one arm and is operative to move relative to the guide to cause the door to move between a closed position () to an open position (). A lever assembly () extends from the handle in pivoting connection with the guide. As the handle moves, the lever assembly is adapted to maintain the handle sufficiently close to the guide such that at least a portion of the handle is operative to slide along the guide.
