US Patent 7984518 Animal escape system

An animal escape device has a central plate, an upper plate and a pair of side plates. The central plate depends downwardly at an angle and has a lower edge positionable in a swimming pool beneath the surface of the water, an upper edge, and parallel side edges. The upper plate is positionable on a deck of the pool and has an interior edge coupled to the upper edge of the central plate and has an exterior edge and side edges. Each of the side plates has a top edge coupled to an associated one of the side edges of the central plate. Each side plate has a bottom edge positionable entirely within the pool and a top edge partially within the water. The side plates form obtuse angles with respect to the central plate.
