    摘要： Ladders and ladder components are provided including a rung assembly that provides an alert to a user of the ladder that they are standing on a particular rung or step. In one example, the lower most rung or step of a ladder includes a rung assembly having an alert mechanism. The alert mechanism may provide an audible and/or other sensory alert to a user when they step on the rung assembly so that the user recognizes their position relative to the ground or supporting surface. In one embodiment, the rung assembly is configured to include a base member, a displaceable member and an alert mechanism, wherein the displaceable member is positioned between the alert mechanism and the base member.

    摘要： Die Erfindung bezieht sich auf eine mehrteilige Leiter (10) mit einer Innenleiter (38), die entlang einer weiteren Leiter (12), verschiebbar ist, wobei die Innenleiter zwischen Holmen (40, 42) verlaufende Auftritte (44, 46, 48) und die weitere Leiter zwischen Holmen (16, 18) verlaufende Sprossen (24, 26, 28, 50) aufweisen. Der unterste Auftritt (44) der Innenleiter (38) ist eine Sprosse und außer der Sprosse (44) sind sämtliche weiteren Auftritte (46, 48, 100, 200, 300) der Innenleiter (38) Stufen.

    摘要： Ladders, ladder components and related methods are provided. In some embodiments, adjustable stepladders are provided which include locking mechanisms that enable height adjustment of the ladder through application of a force towards the rails of the ladder. In other embodiments, spreader mechanisms are provided with cross bracing located and configured to provide additional stability to the ladder while also incorporating a handle that enables efficient collapsing of the ladder while reducing the potential of pinching ones hands or fingers. In another embodiment, a device is provided for selective coupling with the ladder that includes a support or safety rail and an adjustable tray. The device may be coupled with the ladder in a number of different positions including a stowed position.; In another embodiment, a hinge assembly is provided having a magnetic component configured to be magnetically coupled with and temporarily store an object on the ladder.

    摘要： A foldable ladder has a first ladder portion and a second ladder portion hingedly attached to the first ladder portion by a pair of hinge mechanisms. Each hinge mechanism adapted to lock the first and second ladder portions such that the first ladder portion and the second ladder portion form an angle therebetween. The hinge mechanism has a shifting mechanism and a ladder angle selector coupled thereto to allow manual selection of the angle between the first and second ladder portions, and a locking pin to lock the first and second ladder portions at an angular position.
