Abstract

A ladder is provided. The ladder includes coupling components that couple modular storage elements to the ladder. The ladder includes various components to facilitate moving, carrying, and placing the ladder.

First claim

What is claimed is:

1. A ladder configured to couple to a stackable storage unit, the ladder comprising:
a top shelf comprising an upper surface;
a coupling component extending from the upper surface of the top shelf, the coupling component configured to couple the upper surface of the top shelf to the stackable storage unit, the coupling component comprising a first recessed surface, a first rear wall, a first sidewall extending upward from the first recessed surface, a second sidewall extending upward from the first recessed surface, a first rib extending from the first rear wall and the first sidewall above and offset from the first recessed surface, and a second rib extending from the first rear wall and the second sidewall above and offset from the first recessed surface, the second rib distinct from the first rib, the first recessed surface protruding outward from each of the first rear wall, the first sidewall, and the second sidewall, the first rib protruding outward from each of the first rear wall and the first sidewall parallel to and directly above the first recessed surface such that the first rib, the first recessed surface and the first sidewall collectively partially define a first channel that extends horizontally along the first sidewall from a first closed end at the first rear wall to a first open end, and the second rib protruding outward from each of the first rear wall and the second sidewall parallel to and directly above the first recessed surface such that the second rib, the first recessed surface and the second sidewall collectively partially define a second channel that extends horizontally along the second sidewall from a second closed end at the first rear wall to a second open end;
a pair of front legs pivotally coupled to the top shelf;
a plurality of steps extending between the pair of front legs; and
a pair of back legs pivotally coupled to the top shelf.

2. The ladder of claim 1 , further comprising:
a platform pivotally coupled to the pair of front legs, the platform comprising an upper surface; and
a second coupling component extending from the upper surface of the platform, the second coupling component configured to couple the upper surface of the platform to the stackable storage unit, the second coupling component comprising a second recessed surface, a second rear wall, a third sidewall extending upward from the second recessed surface, a fourth sidewall extending upward from the second recessed surface, a third rib extending from the second rear wall and the third sidewall above and offset from the second recessed surface, and a fourth rib extending from the second rear wall and the fourth sidewall above and offset from the second recessed surface, the third rib and the fourth rib distinct from each other, the second recessed surface protruding outward from each of the second rear wall, the third sidewall, and the fourth sidewall, the third rib protruding outward from each of the second rear wall and the third sidewall parallel to and directly above the second recessed surface such that the third rib, the second recessed surface and the third sidewall collectively partially define a third channel that extends horizontally along the third sidewall from a third closed end at the second rear wall to a third open end, and the fourth rib protruding outward from each of the second rear wall and the fourth sidewall parallel to and directly above the second recessed surface such that the fourth rib, the second recessed surface and the fourth sidewall collectively partially define a fourth channel that extends horizontally along the fourth sidewall from a fourth closed end at the second rear wall to a fourth open end.

3. The ladder of claim 1 , further comprising:
a padding coupled to a leg of one of the pair of front legs or one of the pair of back legs.
