ABSTRACT:
An escape hatch for dwellings, such as mobile homes, is provided with a panel fitting within an external wall opening of such dwelling and equipped with a plurality of peripheral latch assemblies engaging such wall. Each latch assembly has internal and external blades on the opposite faces of the hatch panel, and pivotable on a common pivot pin extending through the panel so that in one position they overlie the adjacent portion of the wall. The internal and external blades are jointed by a guide pin extending through an arcuate slot centered on the pivot pin. Conventional burglar alarm devices may be used in conjunction with the escape hatch.
