ABSTRACT:
A new Extendable Pyramid Ladder System for providing a compact stable ladder system which allows the user to access heightened areas by standing on a broad platform while simultaneously providing maximum stability, and for providing compact storage by folding into a swaged shape. The inventive device includes a vertical series of planar support members aligned parallel to one another, a left scissors bracket pivotally secured to the bottom portion of said planar support members, a right scissors bracket secured to the bottom portion of said planar support member opposite of the left scissors bracket where said scissors brackets allow the series of planar support members to extend vertically upward, a recessed handle on the cornice of the top planar support member, and a securing means to retain a swaged shape for the invention when in the storage position. The series of planar support members fit within each other to form a swaged shape for storage. The user may leave the desired number of upper planar support members in the storage position to provide a broad swaged platform for the user to stand upon to reach heightened areas.
