Abstract: 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 such that a front edge remains in a constant or fixed position relative to the rails to which it is coupled so that a user can rely on a fixed or constant position of the front edge of the assembly when climbing or descending the ladder.

Abstract: Ladders and related methods of using and manufacturing stepladders are provided. In one embodiment, a stepladder is provided that comprises a first assembly hingedly coupled with a second assembly. The first assembly has a pair of spaced apart rails pivotally coupled with one or more rungs. The second assembly includes a pair of space apart rails with one or more bracing members extending therebetween. 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. Upon rotation of the two assemblies relative to one another into a stowed condition, components of the second assembly engage undersurfaces of the rungs effecting rotation of at least a portion of each rung relative to the rails of the first assembly.

Abstract: A ladder is provided which may include a positioning system, a fall arrest system, or both. In one embodiment, a rope and pulley system is provided wherein a first end of the rope is coupled to a base section of the ladder, a second end of the rope is coupled with a fly section of the ladder, and the rope extends between a plurality of pulleys. In one particular embodiment, the rope extends between five different pulleys, two being coupled with the fly section and three being coupled with the base section. At least one portion of the rope may extend along the side of the ladder (e.g., along the side of a rail of the fly section) while another section may extend up the front of the ladder between the rails and in front of the rungs.
