ABSTRACT:
A ladder apparatus for providing access to an area over an elevated structure, the ladder apparatus including a housing secured to the elevated structure; a ladder pivotally mounted to the housing, the ladder means including an upper ladder section and at least one lower ladder section mounted to the upper ladder section; and a motorized deploying mechanism structured to controllably allow the ladder apparatus to be pivotally and gravitationally deployed from a stowed configuration to a partially deployed configuration, controllably allow the at least one lower ladder section to be longitudinally and gravitationally deployed from the partially deployed configuration to a fully deployed configuration, longitudinally retract the at least one lower ladder section from the fully deployed configuration to the partially deployed configuration, and pivotally retract the ladder apparatus from the partially deployed configuration to the stowed configuration. A control mechanism operatively controls the motorized deploying mechanism. A power source provides electrical energy to the motorized deploying mechanism and to the control mechanism.
