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.

First claim

The invention claimed is:

1. 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.

2. The ladder of claim 1 , wherein the first arm is directly coupled to the second skirt at a first attachment point and the second arm is directly coupled to the second skirt at a second attachment point, the second attachment point discrete from the first attachment point.

3. The ladder of claim 2 , wherein the first attachment point is aligned with the first side edge of the second portion and the second attachment point is aligned with the second side edge of the second portion.

4. The ladder of claim 1 , wherein the first rail has a first front flange spaced from a first rear flange by a first web, and the second rail has a second front flange spaced from a second rear flange by a second web, the first portion having a first length extending from the first web to the second web, the second portion having a second length extending from the first side edge to the second side edge, the first length greater than the second length.

5. The ladder of claim 1 , wherein the second portion having a proximal edge coupled to the first portion and the first portion has a first depth extending from the first skirt to the second skirt and the second portion has a second depth extending from the proximal edge to the distal edge, the second depth greater than the first depth.

6. The ladder of claim 1 , wherein the distal edge of the second portion includes a lip depending therefrom, the first arm and the second arm coupled to the first portion immediately adjacent to the lip.

7. The ladder of claim 1 , wherein the ladder has a folded configuration and an unfolded configuration, and wherein the deep step is located between about 2 feet and 5 feet from a floor when the ladder is in an unfolded configuration.

8. The ladder of claim 1 , wherein the first portion and the second portion are separate pieces of material.

9. The ladder of claim 1 , wherein the first rail has a first front flange spaced from a first rear flange by a first web and the second rail has a second front flange spaced from a second rear flange by a second web, wherein the first rail and the second rail have a rail periphery defined by a line extending from the first front flange to the second front flange, a line extending from the first rear flange to the second rear flange, the first web, and the second web, and wherein an entirety of the first portion is disposed with the rail periphery.

10. The ladder of claim 9 , wherein a majority of the second portion extends beyond the rail periphery.

11. The ladder of claim 1 wherein the first arm has a channel and the second arm has a channel to strengthen the first and second arms.

12. 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.

13. The ladder of claim 12 , wherein the proximal edge of the extension includes a first lip depending therefrom, and wherein the distal edge of the extension includes a second lip depending therefrom.

14. The ladder of claim 13 , wherein the first lip is coupled to the skirt of the at least one step.

15. The ladder of claim 12 , wherein the first arm includes a first flange portion and a second flange portion, the first flange portion coupled to the tread portion of the extension, and the second flange portion coupled to the skirt of the at least one step.

16. The ladder of claim 15 , wherein the second arm includes a first flange portion and a second flange portion, the first flange portion coupled to the tread portion of the extension, and the second flange portion coupled to the skirt of the at least one step.

17. The ladder of claim 12 wherein the first arm has a channel and the second arm has a channel to strengthen the first and second arms.

18. 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 has a channel and the second arm has a channel to strengthen the first and second arms.
