Abstract: Stepladders and related methods of using and manufacturing stepladders are provided. In one embodiment, a stepladder is provided that comprises a top cap, a first assembly and a second assembly. The first assembly has a pair of spaced apart rails pivotally coupled with the top cap. The second assembly includes at least one rail pivotally coupled with the top cap. The first assembly and second assembly are configured to be displaced relative one another such that the stepladder is selectively positionable between a first, deployed state and a second, collapsed state. The first assembly, the second assembly and the top cap are cooperatively configured such that the at least one rail of the second assembly is at least partially nested within an envelope defined by the pair of spaced apart rails of the first assembly with the step ladder is in a collapsed state.

Abstract: A self-propelled stepladder including a moveable platform having a front end, a rear end, a front pair of wheels secured the front end, and a rear pair of wheels secured to the rear end; a motor having a rotor and a fixed stator coupled to the platform and with the stator imparting rotation to the rotor when electrically energized; a drive mechanism coupled to the platform for transferring rotational motion from the rotor to the wheels; a battery coupled to the platform for providing electrical energy to the motor; a switch mechanism coupled to the battery, the motor, and the driving mechanism for allowing the motor to be selectively energized and de-energized and for allowing the rotor of the motor to rotate and thereby impart forward or rearward motion to the platform via the drive mechanism; and a foldable step ladder having legs terminated at free ends; and a coupling mechanism for removably coupling the free ends of the step ladder to the platform in an extended and substantially vertical orientation for
Abstract: An adjustable stepladder comprising a front and rear leg assembly, each having a pair of parallel legs with coupling apertures at their upper ends and elastomeric stoppers at their lower ends, the leg assembly having a plurality of steps extending transversely between the legs with ends coupled to the legs at intermediate points along their lengths, each of the steps being fabricated with an elastomeric coating upon their upper surface, each of the legs being fabricated of a plurality of components with apertures and with the components coupled together in telescoping relationship with a locking pin positionable through alignable apertures in the areas of overlap and a spring interior thereof to hold the locking pin in a preset orientation, the areas of separation being provided beneath the lowermost step, above the uppermost step, and at regions between the steps; a coupling plate having a planar upper surface with an elastomeric sheet thereover with downwardly extending plates with apertures, the apertures
Abstract: A ladder with an electrical supply and a flip top tool holder is provided, which consists of a pair of front side rails with a plurality of steps supported by and between the front side rails. A head step is mounted to the top ends of the front side rails, while a pair of rear support legs are hinged to the head step. A pair of spreaders are provided, with each extending between one of the front side rails and one of the rear support legs, so as to keep the ladder in a self standing position. A component is carried in the head step, for supplying electrical current therefrom. A structure is coupled to the head step, for holding various tools thereto, for use by a person at the ladder.
