Abstract:
A folding staircase for use in a door opening having a threshold. The folding staircase has a pair of stringers that have an upper end and a lower end that is adapted for contacting a ground surface. The stringers are spanned by at least one tread. A hinge is connected to a floor near the door opening and a threshold plate pivotally connected thereto is movable between a use position and a stowed position. The staircase may be provided with a lifting mechanism that biases the staircase and threshold plate toward their stowed positions. The lifting device provides a variable force that provides more rotational force when the staircase would require a user to bear more of its weight and less force when less of the weight of the staircase would be borne by a user.

Claim (Index 10):
The folding staircase of  claim 9 , wherein said threshold plate has a first hinge flange and a second hinge flange;\n a first mounting bracket having a first wall mount flange including an inner edge and a first hinge flange substantially perpendicular thereto and extending from said first wall mount flange oppositely of said inner edge of said first wall mount flange, said first wall mount flange adapted for being affixed to said inner wall surface; a second mounting bracket having a second wall mount flange including an inner edge and a second hinge flange substantially perpendicular thereto and extending from said second wall mount flange oppositely of said inner edge of said second wall mount flange, said second wall mount flange adapted for being affixed to said inner wall surface; said first hinge flange of said threshold plate pivotally connected to said first hinge flange of said first mounting bracket, said second hinge flange of said threshold plate pivotally connected to said second hinge flange of said second mounting bracket, said threshold plate being pivotable about a pivot axis extending through said first and second hinge flanges of said threshold plate, said pivot axis being fixed with respect to said first hinge flange of said first mounting bracket and fixed with respect to said second hinge flange of said second mounting bracket, said threshold plate being pivotally held between said hinge flanges of said mounting brackets.
