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 user can stand on the deep step in place objects into the attic without having to climb into the attic. A deep step for a ceiling ladder.

First claim

The invention claimed is:

1. A ceiling ladder comprising:
a frame adapted to fit into the ceiling;
a door that fits into the frame;
a top section fixed to the door having a right top rail, a left top rail in parallel with and opposing the right top rail, and a plurality of top steps having a width attached to the right and left rails; and
a second section rotatably attached to the top section having a right second rail, a left second rail in parallel with and opposing the right second rail, and a plurality of second steps attached to the right second rail and the left second rail, at least one of the second steps being a deep step having a width at least 1.5 inches longer than a width of at least another one of the second steps, the right top rail connected by a first hinge to the right second rail and the left top rail connected to the left second rail by a second hinge so the second section can fold onto the top section into a folded position and unfold from the top section into an unfolded position and the door can be closed into the frame with the top and second sections disposed above the ceiling, when in the unfolded position, the top and second sections align to form the ladder on which a user can climb and reach the ceiling with the at least one of the second steps being the deep step located 2-5 feet below the ceiling, the at least one of the second steps being the deep step is a one-piece extrusion that has a first flange whose right side is fastened to and inside of a front flange of the second right rail and whose left side is fastened to and inside of a front flange of the second left rail, a front horizontal portion that extends at an angle from a top of the front flange, a second flange which extends at an angle down from the front horizontal portion and whose right side is fastened to an inside of a rear flange of the second right rail and whose left side is fastened to an inside of a rear flange of the second left rail; and a rear horizontal portion that extends from the front horizontal portion in a coplanar manner and from the second flange and essentially a right angle, and between and behind the second right rail and the second left rail, with the rear horizontal portion having a length which is shorter than a length of the front horizontal portion and a length of the second flange.

2. The ladder of claim 1 wherein the at least one of the second steps being the deep step is fixed in place between the second right rail and the second left rail.

3. The ladder of claim 2 including a first brace which extends from a rear of the at least one of the second steps being the deep step, that is located behind the second right rail and the second left rail, to the second right rail to transfer loads on the at least one of the second steps being the deep step to the second right rail.

4. The ladder of claim 3 including a second brace which extends from the rear of the at least one of the second steps being the deep step to the second left rail to transfer loads on the at least one of the second steps being the deep step to the second left rail.

5. The ladder of claim 4 wherein the at least one of the second steps being the deep step has a lip which extends down from the rear of the rear horizontal portion.

6. The ladder of claim 5 wherein the first brace attached to the second flange and the rear horizontal portion adjacent to the second right rail, and the second brace is attached to the second flange and the rear horizontal portion adjacent the second left rail, with the lip covering over where the first and second braces attached to the rear horizontal portion.
