Abstract:
1. A ladder formed with a collapsible platform assembly comprising: a pair of spaced apart side rails; a plurality of rungs including a top rung rigidly connected between said spaced apart side rails, wherein said side rails extend beyond said top rung and said extending portions of said side rails define grab rails to enable a user to walk between said side rails while holding on to said grab rails; a platform rotatably connected directly to said top rung so as to be movable between a collapsed position in which said platform is co-planar relative to said side rails and an extended position in which said platform is not co-planar relative to said side rails to enable said platform to overhang a roof of a building when said ladder is disposed against a building and said top rung of said ladder is at an elevation higher than a lowest elevation of said roof; and a collapsible hand rail assembly including at least two links directly coupled together by a pivot and rotatably connected directly to said platform and rotatably connected directly to one of said side rails so that said hand rail assembly is movable between a storage position wherein said platform and said hand rail assembly are co-planar with said side rails and a use position in which said hand rail assembly is not co-planar with said side rails, said hand rail assembly including at least one hand rail to enable a user to hold on when said collapsible hand rail assembly is in said use position.
