The upper ladder section has an upper end pivotally secured to the upper platform and a lower end pivotally secured to the lower ladder section. The lower ladder section has an upper end pivotally attached to both the outer end of the lower platform and the lower end of the upper ladder section in a manner such that the lower ladder section is free to pivot between a folded position next to the upper ladder section and an extended position in which the upper ladder section and the lower ladder section combine to form a straight continuously aligned ladder structure.
