Abstract: A ladder having a first rail and a second rail. The ladder having a standard rung having a width permanently attached to the first rail and the second rail. The ladder having a first wide rung having a width greater than the width of the standard rung, which is permanently attached to the first rail and the second rail. The ladder having a second wide rung having a width greater than the width of the standard rung, which is permanently attached to the first rail and the second rail. The first wide rung and the second wide rung are disposed in a work zone of the ladder. The work zone of the ladder is where a user typically stands on the ladder while performing tasks. The standard rung is disposed outside the work zone.

Abstract: An extension ladder having a base section and a fly section. The fly section has a right local reinforcement disposed inside a right fly rail of the fly section at locations of highest bending moment of the right fly rail when a force is applied to the right fly rail. The right local reinforcement is shorter than a length of the right fly rail. Loads applied to the right fly rail are transmitted to the right local reinforcement so the right fly rail may be thinner than if there was no right local reinforcement present. A method for producing a ladder rail with a local reinforcement between a top rail flange and a bottom rail flange. A method for using an extension ladder.

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.

Abstract: In some embodiments, a multipurpose ladder has a first inner section. The ladder has a first articulated hinge and a second articulated hinge. The ladder has a second inner section. The ladder has a first outer section. The ladder has a first locking bar. The ladder has a second outer section. The multipurpose ladder may have a plurality of brackets disposed about outer rails of the outer sections. The brackets provide support to each of the outer rails and strengthens them against bending forces so the rails can be thinner and of lighter weight. The ladder may have an ANSI duty rating of 1 A or an ANSI duty rating of 1 AA.
