Reinforced spreader ladder step and ladder handle, ladders incorporating same, and related methods

A ladder, comprising:

• a first assembly including a first pair of rails and a plurality of rungs extending between and coupled to the first pair of rails;
• a second assembly including a second pair of rails, the second pair of rails being pivotally displaceable relative to the first pair of rails between a collapsed configuration and an expanded configuration;
• and
• a spreader mechanism comprising a pair of jointed linkages coupled with the first assembly and with the second assembly, the spreader mechanism including a platform component having a consistent cross-section across its lateral width.

A ladder, comprising:

• a first assembly including a first pair of rails and a first plurality of lateral supports extending between and coupled to the first pair of rails;
• a second assembly including a second pair of rails and a second plurality of lateral supports extending between and coupled to the second pair of rails, the second pair of rails being pivotally displaceable relative to the first pair of rails between a collapsed configuration and an expanded configuration;
• and
• a handle coupled to a first rail of the first pair of rails, the handle having an inner end including a tip movable between:
• a first position laterally inward of a laterally innermost surface of a rear wall of a second rail of the second pair of rails;
• and
• a second position contacting or laterally outward of the laterally innermost surface of the rear wall of the second rail of the second pair of rails.
