Abstract: A self leveling stepladder with a universal hinge joint providing many new advantages that traditional a-frame step ladders are not capable to offer.

Abstract: The present invention relates to ladders and, more particularly, various configurations of ladders including straight and extension ladders, as well as to methods relating to the use and manufacture of such ladders. In accordance with one embodiment of the present invention, a ladder is provided that includes a first pair of spaced apart rails and a plurality of rungs extending between and coupled to the first pair of spaced apart rails. The ladder also includes a pair of lateral support members, wherein each support member is selectively displaceable in a lateral direction relative to an associated rail. Additionally, the ladder includes a pair of adjustable legs, each leg having a first end slidably coupled to an associated rail of the first pair of spaced apart rails and being slidably coupled to an associated lateral support member.

Abstract: The assembly includes a first arcuate tube attached to a ladder. A second arcuate tube is slidably disposed in the first arcuate tube. A lock subassembly is disposed on the first arcuate tube for limiting movement of the second arcuate tube relative to the first arcuate tube. A step lever extends along the first arcuate tube and is coupled with the lock subassembly. A first flange and a second flange each extend radially from the first arcuate tube. An actuating member defines a cam surface abutting the second flange. A bar extends through the flanges and attaches to the actuating member. The step lever attaches to the actuating member to move the actuating member and cause the cam surface to slightly deform the first arcuate tube about the second arcuate tube and engage the second arcuate tube. A foot is pivotably disposed at each end of the second arcuate tube.

Abstract: A device for stabilizing a ladder including a first stabilizing member having a predetermined fixed first length, a second stabilizing member having a predetermined fixed second length, a support structure for being mounted to the ladder at a predetermined location, the support structure being mounted to an upper portion of the first and the second stabilizing member, respectively, the support structure for holding the upper portion of the first and the second stabilizing member in proximity of a first frame rail and a second frame rail of the ladder, respectively, such that the first and the second stabilizing members are rotatable around a first axis oriented substantially parallel to rungs of the ladder, and a connecting member having a predetermined length removable mounted to the first and second stabilizing member at a predetermined distance to the upper portion of the first and second stabilizing member.

Abstract: A ladder comprises a pair of main stiles, a series of centrally-hinged rungs with ends articulated to the two main stiles, whereby the ladder can adopt a folded inoperative configuration in which the main stiles are alongside each other and an extended operative configuration in which the main stiles are spaced from each other, and means for stopping the ladder in the extended operative configuration. The main stiles are articulated together at their upper ends and the ladder further includes a single auxiliary stile articulated at its upper end to the two upper ends of the main stiles about an axis substantially perpendicular to the articulation axis of the two main stiles. The auxiliary stile is movable between a position alongside the two main stiles, corresponding to the folded inoperative condition of the ladder, and a position spaced from the main stiles, corresponding to the extended operative condition of the ladder.

Abstract: This invention relates to improvements in TRIPODS and more particularly to tripod connections.The invention includes a link portion which links tripod leg portions either formed as legs for ground contact or as portions for engaging with legs for ground contact so as to enable the legs to be arranged into a tripod like configuration, converging toward one another and interconnected together adjacent an upper portion thereof.The tripod can be in the form of shear legs, scaffolding supports, ladders and the like.

Abstract: A step ladder for use on an uneven surface including an arcuate leveling member adapted to hold the step ladder straight on an uneven surface with means for securing the leveling member in any selected position.
