Abstract
A ceiling ladder having a plurality of sections that can be climbed by a user when in an unfolded position into an attic and that can be folded together into a retracted position to be stored above the ceiling. The ladder has a deep step, which has a width greater than the width of other steps of the ladder, in which is located between about 2-5 feet from the floor when the ladder is in the unfolded position so that a user can stand on the deep step and place objects into the attic without having to climb into the attic.
Claims18
A ladder comprising:
- a first rail;
- a second rail, the second rail spaced from and parallel to the first rail;
- a deep step coupled to the first rail and the second rail, the deep step including a first portion disposed within a footprint of the first rail and the second rail and a second portion projecting beyond the first rail and the second rail, the first portion including a first standing surface with a first skirt and a second skirt depending from the first standing surface, the second portion including a second standing surface that is coplanar with the first standing surface, the second portion having a proximal edge coupled to the first portion, a distal edge opposite the proximal edge, a first side edge, and a second side edge opposite the first side edge;
- a first arm extending from the second skirt to the second portion adjacent to the distal edge, the first arm disposed adjacent to the first side edge;
- and
- a second arm extending from the second skirt to the second portion adjacent to the distal edge, the second arm disposed adjacent to the second side edge;
- wherein the first arm and the second arm are directly coupled to the second skirt.

A ladder comprising:
- a rail assembly including a first rail, a second rail, and a plurality of steps coupled to the first rail and the second rail, the second rail spaced from and parallel to the first rail;
- and
- at least one step of the plurality of steps including an extension that projects from the at least one step beyond the rail assembly, the at least one step having a skirt depending therefrom, the extension including a tread portion with a proximal edge coupled to the skirt, a distal edge opposite the proximal edge, a first side edge, and a second side edge, the extension supported at least in part by a first arm and a second arm, the first arm coupled to the extension adjacent to a junction of the first side edge and the distal edge, the second arm coupled to the extension adjacent to a junction of the second side edge and the distal edge;
- wherein the first arm and the second arm are directly coupled to the skirt of the at least one step.

- a first arm extending from the second skirt to the second portion adjacent to the distal edge, the first arm disposed adjacent to the first side edge;
- and
- a second arm extending from the second skirt to the second portion adjacent to the distal edge, the second arm disposed adjacent to the second side edge;
- wherein the first arm has a channel and the second arm has a channel to strengthen the first and second arms.
