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 9):
A folding staircase adapted for use in a door opening within a wall having an inner wall surface located within an indoor space, and an outer wall surface located in an outdoor space, said door opening including a threshold, said door opening for receiving a door that separates said indoor space from said outdoor space, said door movable between an open position locating said door outside of said opening and a closed position that locates said door within said opening, said folding staircase comprising:\n a pair of stringers spanned by a tread, said staircase having a lower end adapted for contacting a ground surface and an upper end adapted for abutting said outer wall surface; a hinge affixed to said stringers, said hinge having a floor mounting portion and a threshold plate that is pivotally affixed to said floor mounting portion, said threshold plate having a use position wherein said threshold plate overlies said threshold and spans said door opening and a stowed position wherein said threshold plate is located within said indoor space; said door being movable between said open and closed positions when said threshold plate is in said use position and said door being movable between said open and closed positions when said threshold plate is in its stowed position.
