Abstract
According to the present invention, there is provided a retractable staircase for a recreational vehicle. The retractable staircase has a translational section, which includes at least one-step. The translational section moves between an extended and a retracted position relative to the recreational vehicle. In the extended position, a rotational section, which also includes at least one step, moves between a lowered position with the step below the step of the translational section and an upside down and inverted position above the step of the translational section to provide for movement of the translational section to the retracted position.
Claims25
A retractable staircase for a recreational vehicle, comprising:
- a translational section including at least one step, wherein the translational section is moveable between an extended and a retracted position relative to the recreational vehicle;
- a rotational section including at least one step, moveable between a lower position with the at least one step of the rotational section below the at least one step of the translational section when the translational section is in the extended position and an upside down inverted position above the at least one step of the translational section to provide for movement of the translational section to the retracted position;
