ABSTRACT:
A pair of laterally positioned struts are interconnected by a plurality of rungs, each rung being formed of a pair of pivotally mounted rung sections. A central rod extends between the inner ends of the rung sections of each rung, the central rod being rigid with a fastener member beneath each pair of rung sections. The inner ends of each pair of rung sections are individually pivoted to a fastener member. A pair of diverging stabilizing rods are centrally joined to a joinder member slidably on the central rod and positionable in direct underlying and supporting engagement with the fastener member of the lowermost rung in the open position of the ladder.
