Abstract:
1. An access ladder for an access hole in a building comprising: a plurality of sections which telescope relative to each other between an extended position, where the sections define a plane and a user can climb the sections, and a retracted position where the sections are folded on each other, several of the sections having at least one step which moves between an unfolded position where the user can stand on the step when the sections are in the extended position, and a folded position when the sections are in the retracted position, each section slides relative to another section of the plurality of sections which it is in contact in order for the sections to telescope, the plurality of sections include a plurality of middle sections, the plurality of sections includes a bottom section which contacts a floor when the sections are in the extended position, the middle and bottom sections have springs which contact the step to cause the step to move into the folded position as the section moves into the retracted position, each section when moving into the retracted position rises until a section is even with a section immediately behind it before being stopped, each section has opposing side rails, the middle sections and the bottom section have a step stop attached to each side rail which contacts and unfolds a folding step attached to a section immediately behind the section to which the stop step is attached as the section to which the stop step is attached moves into the extended position; and a mounting section for attachment to an end of the access hole, the plurality of sections includes a top section which slidingly connects with the mounting section.
