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 7):
The folding staircase of  claim 6 , wherein wall mounting flanges, said floor flanges, and said hinge flanges on each of said mounting brackets are joined to form a corner.
