Abstract
A ventilator hatch assembly for vehicles, watercraft and the like, which is characterized by having a hatch member, which is interconnected to a mounting frame restable within a ventilation hatch opening for pivotal movements between alternative open ventilating and closed, latched, non-ventilating positions. The hatch cover and mounting frame are interconnected by separable hinge means and separable flip-action or snap-action latch means which operably cooperate to accommodate rapid opening and closing movements of the hatch cover and also to facilitate complete and rapid removal of the hatch cover from the hatch opening to permit the latter to serve as an emergency exit from the vehicle or craft.
