  • Patent number: 5255479
    Abstract: An escape hatch that is added to an occupied structure by cutting an opening in an exterior wall that is then closed with the main body of the hatch. A pair of pivotally mounted handles are provided on the interior wall of the hatch so that when both handles are pivoted, the hatch may be pushed out so that it falls onto the ground outside the structure and so that the occupants of the structure may then crawl through the opening. An exterior wall of the hatch is larger than the opening so that the hatch cannot be pushed into the interior of the structure by a person outside it. The handles are designed to be opened with minimal force and the hatch construction includes numerous features that ensure against jamming of the hatch when it needs to be opened.
