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： Elevated work platform apparatuses, as well as associated methods, are provided. In one particular embodiment, an elevated platform apparatus is provided comprising a first assembly having a pair of rails coupled with a plurality of rungs, a second assembly hingedly coupled with the first assembly, a platform pivotally coupled with the first assembly and configured to extend to, and engage a portion of, the second assembly. The apparatus further includes a cage associated with the platform. The cage may include at least one bar and at least one gate, the at least one gate being configured to swing in a first direction upon a user stepping on to the platform from the first rail assembly, and then swing back to a closed position after the user is standing on the platform.

摘要： Ladders and ladder components are described herein, including multipurpose and adjustable ladders. In one embodiment, a ladder includes a first assembly having rails and rungs, a second assembly having rails and rungs, and one or more hinges coupling the first and second assemblies together such that the first and second assembly may be positioned relative to one another in at least a position or state and at least a second position or state. A top cap is coupled to the rails of the first assembly, such that when the first and second assemblies are in the first position, the rails of the second assembly do not contact the top cap. When the first and second assemblies are in the second position, each rail of the second assembly is at least partially nested in one of a pair of channels formed in the top cap.

摘要： An alert mechanism (170) for use with a displaceable member of a ladder rung assembly, the alert mechanism (170) being configured to provide an audible alert when the displaceable member is displaced from the first position to the second position, wherein the at least one alert mechanism (170) includes: a pin (190); a collar (200) coupled with the pin (190) and movable relative to the pin (190) between a first collar position and a second collar position; and a detent mechanism (204) configured to hold the collar (200) at the first collar position relative to the pin (190) until a force of a specified magnitude is applied to the collar (200), whereby the collar (200) is displaced from the first collar position toward the second collar position upon application of the force of the specified magnitude.
