Abstract
A fan fold vent for covering the opened ridge of a roof allowing ventilation of static air from an attic space of a building consisting of multiple vent sections connected by soft pliable hinges which allow the sections to fold on top of each other and form a stack for easy transportation and handling. The soft, pliable hinges are staggered at each junction of two vent sections, one hinge being on the top surface on the junction and the following hinge being on the bottom surfaces on the junction. Each vent section constitutes a unitary semi-rigid panel adjustable to the configuration of a roof and contains: a support structure on its bottom surface to prevent collapse or warping of the panel; and ventilation means for guiding air from the attic space to the exterior which includes: rows of vent slots and slats running longitudinally on two sides of the panel; and two vertical exterior baffles integral and running parallel with the rows of the slats to create a vacuum over the rows of slots and slats.
